Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of clamps, and in particular relates to a pneumatic clamp with a protective function. Background Art
[0002] In the plastic processing industry, products need to be clamped by robots. The robot's clamping arm is controlled by pneumatic or electric means. The existing clamps do not have corresponding protective devices and cannot be installed with detection switches, resulting in an inability to provide feedback signals to the robot and low flexibility in use. Utility Model Content
[0003] In order to solve the above technical problems, the utility model provides a pneumatic clamp with a protective function, which has the advantage of high flexibility.
[0004] In order to achieve the above object, the technical solution of the utility model is as follows:
[0005] A pneumatic clamp with a protective function comprises: a clamp body, on which an air pipe connection assembly is installed; and clamp arms symmetrically arranged on both sides of the clamp body, on which a clamp head is installed, and on which a protective pad is installed.
[0006] As a preferred solution of the utility model, the air pipe connection assembly includes: a tailstock connected to the clamp body, and an air pipe joint provided on the tailstock and extending into the clamp body.
[0007] To implement the above technical solution, the arrangement of the air pipe joint facilitates the movement of the pneumatic clamp.
[0008] As a preferred solution of the utility model, a piston is installed between the clamp arms, and the piston is arranged on the clamp body.
[0009] To implement the above technical solution and the arrangement of the piston, the extension between the clamping arms can be better achieved.
[0010] As a preferred solution of the utility model, sealing members are installed at both ends of the piston.
[0011] By implementing the above technical solution and setting the sealing element, the stability of the piston movement is improved.
[0012] As a preferred solution of the utility model, a hinge shaft is installed between the two clamping arms.
[0013] As a preferred solution of the utility model, a magnetic switch is installed between the clamp body and the tailstock.
[0014] To implement the above technical solution and set the magnetic switch, the pneumatic clamp can be precisely controlled.
[0015] In summary, the utility model has the following beneficial effects:
[0016] The air pipe interface is connected to the power supply. When ventilation is carried out, the gas enters the shell through the air pipe interface. During the ventilation process, the internal pressure increases, causing the two sets of pistons to move outward, causing the clamping arms to move, and under the action of the hinge shaft, the product is clamped; in this process, the spring is squeezed and has a restoring force. When the air is cut off, the clamping arm returns to its initial state.
[0017] By changing the air pipe to an embedded type, the joint is protected and the removal and installation of the air pipe are facilitated; the setting of the magnetic ring improves the flexibility of the use of the pneumatic clamp, and the position of the magnetic switch can be adjusted according to the size of the product to adapt to different product sizes.

[0024] Example
[0025] A pneumatic clamp with protective function, such as Figure 1 to Figure 2As shown, it comprises: a clamp body 1 on which an air pipe connection assembly is installed; and clamp arms 4 symmetrically arranged on both sides of the clamp body 1 , on which a clamp head 5 is installed, and on which a protective pad 6 is installed.
[0026] The air pipe connection assembly includes: a tailstock 2 connected to the fixture body 1, and an air pipe joint 3 arranged on the tailstock 2 and extending into the fixture body 1. The air pipe joint 3 adopts an embedded design to protect the air pipe joint 3.
[0027] When the gas is connected, the clamping arms 4 move, so that the clamping head 5 clamps the product; a piston 7 is installed between the clamping arms 4, and the piston 7 is arranged on the clamp body 1.
[0028] Specifically, sealing members 8 are installed at both ends of the piston 7, a hinge shaft 9 is installed between the two clamp arms 4, and the rubber pad installed on the clamp head 5 is of a buckle-embedded type for easy replacement.
[0029] Finally, a magnetic switch is installed between the clamp body 1 and the tailstock 2, and a magnetic ring is installed near the magnetic switch to improve the signal transmission between the magnetic switch and the magnetic ring. The magnetic ring moves with the piston 7, and the position of the magnetic switch is adjusted according to the size of the product to clamp or release the product. Under the action of the feedback signal, the air is cut off to release the product.
[0030] The air pipe interface is connected to the power supply. When ventilation is performed, the gas enters the shell through the air pipe interface. During the ventilation process, the internal pressure increases, causing the two groups of pistons 7 to move outward, causing the clamping arm 4 to move, and under the action of the hinge shaft 9, the product is clamped; in this process, the spring is squeezed and has a restoring force. When the air is cut off, the clamping arm 4 returns to its initial state.
[0031] By changing the air pipe to an embedded type, the joint is protected and the removal and installation of the air pipe are facilitated; the setting of the magnetic ring improves the flexibility of the use of the pneumatic clamp, and the position of the magnetic switch can be adjusted according to the size of the product to adapt to different product sizes.
