As long as it is a mechanism that requires multiple fixed points for linear motion and rotary motion, indexing pins(plunger) can be used for positioning.
The indexing pin(plunger) consists of a pin body, a pin head, a handle, and a built-in spring.
Indexing pins(plungers) are generally used for mechanical devices, fixtures, molds, automated machinery, etc.
Indexing plungers usually have the following types: reset indexing plungers, self-locking indexing plungers, full-thread indexing plungers, short-threaded indexing plungers, indexing plungers with flange, indexing plungers with pull ring, handle type Indexing plungers, T-shaped indexing plungers.
The indexing pin(plunger) is suitable for various occasions such as the indexing, positioning and stop limit of the fixture.
Boyi company refers to the international standard Elesa+Ganter E+G standard indexing plungers.











Reset type indexing plunger
1. The front end is usually in a prominent state;
2. The front end retracts when the knob is pulled out;
3. If you release the knob, the front end will restore the protruding state through the action of the built-in spring force;
Self-locking indexing plunger
1. The front end is usually in a prominent state;
2. The front end retracts when the knob is pulled out;
3. If you rotate 90° while keeping it pulled out, the retracted state of the front end can be locked;
4. When unlocking the locked state, only need to rotate 90° while maintaining the pulled out state;
5. If the knob is released, the front end will restore the protruding state through the action of the built-in spring force;
Flange type indexing plungers:
1. With flange, adjustable left and right directions;
2. The body has no thread, and the flange part has two installation holes, which can be fixed by locking the flange with countersunk screws;
Compact indexing plunger
1. The total length is 2/3 of the ordinary index pin, which can be used in a small space;
2. This type of indexing pin has a hexagonal plane, when the pin head is in the retracted position, it can be easily installed and tightened with a hexagonal wrench;
Short thread
1. This type of indexing pin has a compact size and a short threaded part, which is suitable for installation of thin metal plates;
2. In view of its shape, this kind of index pin can assist in locking during installation, and can also be used as an index pin;
3. When self-locking, rotate the pull ring 90° to fix it in one position;
1.Inventory: a large amount of inventory for customers to choose.
2. Delivery time: 1-3 days, except for customized products.
The toggle clamp buckle is designed according to the mechanical principle of the double rocker mechanism in the plane four-bar mechanism, and its basic structure is composed of four components such as a connecting rod, a frame and two connecting rods;
When the two hinge points of the connecting rod and the connecting rod and the hinge point of one of the connecting rod and the frame are in the same straight line, the mechanism is at the dead center position. At this time, no matter how big the reaction force (except destructive reaction force) is, the pressed work piece cannot loosen the indenter. This is the dead-point clamping principle in mechanical mechanics;
Clamping force refers to the maximum pressing force of the indenter on the workpiece when the clamp is in the locked position without mechanical deformation. This pressing force is generated when the indenter is adjusted to the position closest to the mounting seat on the lever arm. The pressure of the indenter on the workpiece is not constant. It varies with the different positions of the indenter on the arm. When it is far away from the mounting seat, the clamping force decreases;
