toggle hold-down clamp

In 2019, SPEP has released a full family of toggle clamps to its catalog.   These are a fantastic addition to our industrial access hardware because toggle clamps are like the wall-mounted light switch of the manufacturing world.   They are used for situations that require workpieces to go “on” and “off” consistently, reliably and easily.  They are used on applications that vary from test fixtures to manufacturing jigs to pressure vessels.  While the large collection may be a little intimidating when you’re getting introduced, the selection of the right one based on functionality of these versatile tools are quickly learned.

Toggle clamp used on fixture

First, toggle clamps are simple mechanisms that hold things together.  They generally consist of 3 primary components that are of interest:

  1.  a handle: the user-interface to operate the mechanism
  2.  a clamping arm: the contact point with the assembly or workpiece
  3.  a base: the permanent attachment point.  

There are also linkages that affect the motion (or stroke), and attributes like the holding capacity and the clamping force.  While applications may vary, I’ve found that most people that need toggle clamps aren’t really concerned with these details because it’s more of a size & function application (and the application generally doesn’t come close to the holding capacity or clamping force).  However, just to be complete:  the “Holding Capacity” is how much force is required to overcome the clamp when it is in the locked position and the “Clamping Force” is how much force the clamp can push down on a work piece.        

Toggle Clamps work base on a simple linkage-system.  The system “locks” or “clamps” when it is over-center.  When a clamp is in the “locked” or “over-center” position, it can only be released by pulling the handle or by overcoming the holding capacity. 

There are three basic toggle movements:  vertical-hold down clamps  (force is perpendicular to the base), horizontal-push clamps (force is parallel to the base) and horizontal-pull clamps (force is also parallel to the base, but hooking or pulling something in- also known as a squeeze clamp). 

Within each category, there are several variations of handle movements. 

Furthermore, there are several items in our catalog that aren’t located in the toggle section that could be used for the “Pull” Toggle functionality (aka- the “Squeeze” Toggle):

These are generally called “Draw latches” and are considered very close cousins to the toggle switch.  They are used in a similar applications.  If you want to sound like a pro, try using the following terminology:

As an engineer at SPEP (a supplier of industrial access hardware- like hinges, latches & handles), I'm fortunate to work in industries spanning everything from controls to medical devices to RVs.  Even though we have more than 3000 items in our catalog, we have more than 3000 additional products that are custom made for per customer request.   As you can imagine, these additional products are a result of working on fast-paced projects.  In order for these projects to be successful, we need to generate and turn-around prototypes, drawings & digital models quickly. 
 

While I’ve picked-up a few tricks by taking (and teaching) some SolidWorks courses and certifications (like the CSWA & CSWP).   I’ve found a separate methodology based on 2 principles.  The first is to try to get really good at a few moves (instead of knowing every move).  This comes from a Bruce Lee quote: “I don’t fear someone who knows a thousand different kicks.  I fear someone who has practiced a kick a thousand times.”  The second principle is to minimize time clicking in menus, and maximize time designing parts. This is done by working smart and using a variety of hot keys & mouse gestures.

In order to break the habit of clicking in the Command Manager and using the Feature Manager, force yourself to practice by going in “Jedi Training Mode”.  This is done by pressing F9 (hide Feature Manager Tabs) and F10 (hide Command Manager). 
 

One last tip before getting into the shortcuts. Remember that shortcut keys are almost entirely customizable. If there is a certain feature you like but it’s buried away on a remote menu you can give it its very own shortcut through the options menu.

  1. Before you get started- see if the parts exist already.  We load all our catalog parts on a variety of sites including our website (www.spep.com),  3D Content Central and www.3dx-us.com.  There are other places like McMaster-Carr, Grainger and GrabCAD.com that are also fantastic resources.  If those don’t work perfectly, feel free to kit-bash them (more on that later).  If you need something from our catalog adjusted for your application, let us know and we’ll work on it.  
     
  2. “s”  (Shortcut-superman key) – this shortcut key is genius and situational.  It will adjust depending on what type of file you are working on AND what you are doing in that files (for example: making a sketch in part mode is different from inserting a part in a drawing).

  3. Mouse gestures – also situational.  I’m better at using this in sketch mode than anywhere else. For those of you who don’t know how to activate this- hold your right mouse button down and drag.  You will see a circle with 4 icons in a ring surrounding your mouse cursor.  Simply sweep the cursor to one of the icons.

  4. Right mouse button (situational)- this opens a good number of commands.  Please note- #2, 3 & 4 are the Trinity of hot keys.   Almost every possible function of SolidWorks is available from these 3.

  5. “f” (fit on screen).  I find myself sometimes looking at a blank screen.  This is an easy way to get a part that is either zoomed-out or zoomed-in way too far quickly centered back on your screen.
     
  6. Ctrl-Tab (toggle between open files).  This is similar to using “Alt-Tab” to toggle between open applications on your computer but you can use to toggle between different parts that you have open within SolidWorks.  It’s fantastic when you’re working on an assembly.

  7. Enter (repeat previous command).  I find that this comes in most handy when adding rounds & draft.
     
  8. Ctrl-8 (orient normal to plane)- get away from using the view cube or the heads-up display.  Both of those take multiple clicks.  Ctrl-1, 2, 3, 4, 5, 6, 7 (orientation).  These seem difficult to remember at first BUT it makes sense if you think about it.  Control 1 TOP, Control 2 BOTTOM, Control 3 RIGHT, etc…
     
  9. “a” – This is great for toggling between an arc and a line in sketch mode OR different “types” in sketch mode (for instance- a center point rectangle vs a corner rectangle)

  10. Other window hotkeys (Ctrl-Z, Ctrl-C, Ctrl-V, Ctrl-N, Ctrl-O).   If you use and apply these in SolidWorks, you’ll find that you automatically get faster at using Microsoft Office products as well.  So- as soon as you open SolidWorks, try to hit “Ctrl-O” to open an existing file or “Ctrl-N” to open new file instead clicking.   

If you discipline yourself to use these shortcuts for 30 days, you’ll find yourself spending more time on building and less time digging through menus.  This will make you far more proficient in your classes, give you a higher chance to pass the CSWP but most importantly, the speed you want when you are making your latest creation.
