Wixroyd Side-Thrust Pins 32810 - 32890
What is...
Wixroyd Side-Thrust Pins are an economical way to clamp, hold and position components - from low height PCB's to relatively large castings. Side-Thrust Pins come in a variety of sizes.
Applications
Simple to mount, easy to use and space saving.
- Easy handling.
- Minimum mounting space.
- Easy and rapid changeover.
- Ideal for flat pieces.
- Reduced clamping times.
- Constant clamping pressure.
Typical Applications
Side-thrust Pins find applications in the following industries and more:
- Automotive
- Aviation
- Electronics
- Computing
- Plastics
- Medical
- Precision engineering
- Tool manufacturing
Positioning and clamping even extremely flat parts (e.g. metal sheets and printed circuit boards).
Positioning and clamping round metal using the deep drawing effect.
Space saving positioning and clamping from the inside to the outside.
Positioning and clamping different profiles when welding. Material expansions compensated by flexibility of the Side-thrust Pin.
Installation
Calculating formulae for pin location (x) and pin positioning (k)
Pin Location (x)
Please refer to the part tables for dimension x, or use the following formulae.
AÂ Â When workpiece height is higher than C-r, x is calculated by:
BÂ When workpiece height is lower than C-r, x is calculated by:
Pin Positioning (k)
For positioning co-ordinates:
Formula Key:
- W = Workpiece width (tolerance)
- F- = Prestressing
- F+ = Stress (range of spring tolerance)
- F = [(F-) + (F+)] - nett of prestress & stress
- T = Workpiece Tolerance
- Y = Workpiece Height
- B = Diameter of selected Side-thrust Pin
- C = Height of selected Side-thrust Pin
- r = Radius of selected Side-thrust Pin
- X = Distance between side thrust pin and workpiece edge
- S = Diameter of positioning dowel or stop
- K = Hole centre distance between positioning down/stop and Side-thrust Pin
General Guidance
The best selection of Side-thrust Pins is made with consideration to the following four factors:
a) Pin Size Ø
b) Pin material
c) Sealed or non-sealed pin
d) Required pin force
Pin size Ø
| Pin size Ø | Application |
| 3 mm | Circuit boards, thin metals |
| 4 mm | Electronics, measuring equipment, small precise parts |
| 5 mm | Drilling jogs, sheet metal, measuring devices, welding fixtures |
| 6 mm | Fixtures for light machine parts and castings |
| 8 mm | Fixtures for medium machine parts and castings |
| 10 mm | Fixtures for heavy machine parts and castings |
Pin Material
Plastic Pins for sensitive parts. Stainless Steel Pins in corrosive environments.
Sealed or Non-sealed Pin
Use Side-thrust Pins with seal
e.g. 32820, 32850 etc.
| Application | Situation |
| Milling, drilling, reaming, broaching, honing, engraving | Machining |
| Washing, polishing, painting, sand blasting | After machining |
Use Side-thrust Pins without seal
e.g. 32810, 32840 etc
| Gluing, welding, hard soldering | Prior to machining |
| Gripping, inserting, fitting | Final mounting |
| Measuring, controlling, loading | Quality assurance |
| Soft soldering, checking | Processing circuit boards |
