When cutting the pins, the optical module is usually clamped by a clamp first, and then the pins of the optical module are cut. At the same time, the clamping and pin cutting operations are respectively driven by their own driving sources such as cylinders. As the number of cylinders increases, the probability of failure will increase, thereby affecting the efficiency of pin cutting. Utility Model Content

[0003] The utility model provides a pin cutting device to solve the above-mentioned deficiencies of the prior art and solves the current method of separately controlling the pin cutting and positioning, so as to reduce the failure rate.

A moving rod is provided on the L-shaped plate, and an outer moving plate is provided at the outer end of the moving rod at the same height, and a pair of vertical rods are passed through the outer moving plate, and mounting end plates are installed at the upper and lower ends of the vertical rods, and the mounting end plates are installed on the vertical plate. A spring is sleeved on the vertical rod, and the spring is located between the outer moving plates.

[0008] By means of the second fan-shaped plate and the fan-shaped plate, when they are driven by the rotating shaft to rotate, the cutters can be brought close to each other, and then the pin cutting operation can be performed. In addition, the clamps can be brought close to each other, and the optical module can be clamped by the clamps. At the same time, when operating, the clamps are first brought close to each other by the second fan-shaped plate, and then the optical module is clamped by the clamps.

[0009] Furthermore, a plurality of groups of limiting grooves are respectively provided on the upper and lower walls of the cushion block to facilitate limiting the pins.

[0011] Furthermore, the inner wall of the clamping plate is provided with a plurality of arc grooves to avoid damage to the optical module during clamping.

[0012] Furthermore, a clamping groove is provided on the peripheral side of the arc-shaped groove, thereby ensuring the axial limiting effect of the optical module.
