[0017] As shown in Figs. 1-2 A kind of precision automatic detection equipment clamp, it is applied to automatic detection equipment, wherein the embodiment includes clamp base 1, the clamping station 2 for placing the product to be detected in the middle of clamp base 1 and multiple clamping cylinders 3 for clamping the product to be detected around the clamping station 2, each clamping cylinder 3 bottom is fixed with bearing seat 4, each bearing seat 4 is movably arranged on the clamp base 1, for being able to adjust position according to the shell shape of product to be detected, further including locking assembly 5, for being able to fix clamping cylinder 3 to adjustment position.

[0018] The clamp base 1 of the embodiment is disc-shaped, with clamping station 2 in the middle, and multiple clamping cylinders 3 are distributed in the circumference of clamp base 1, the action of the cylinder can be driven by compressed air, the internal piston moves under the action of air pressure to clamp the product to be detected in the middle clamping station 2, which can provide uniform and accurate clamping force, ensure the stability of workpiece position during processing, and is beneficial to improve processing accuracy. And bearing seat 4 is provided at the bottom of each clamping cylinder 3 and movably mounted on clamp base 1, so that clamping cylinder 3 can adjust position according to the shell shape of product to be detected. So that the clamp can flexibly adapt to products of different shapes, especially for irregularly shaped side walls of the product to be detected, through reasonable layout, it can be more accurately positioned and clamped, avoiding the situation that clamping is not firm or deviated due to irregular shape. Clamping cylinder 3 is fixed in the adjusted position by locking assembly 5, which can ensure the stability of the clamp after adjusting the position, prevent the position of the clamp from changing due to vibration or external interference during detection, ensure the stability of the product on the clamping station 2, and prevent detection errors caused by inaccurate clamp position.

[0019] As shown in Fig. 1As shown, the end face of the clamp base 1 of the embodiment is provided with an annular guide rail 11 around the clamping station 2, and the bottom of the bearing seat 4 is provided with a sliding block 41 slidably mounted on the annular guide rail 11. Specifically, a annular guide rail 11 is fixed on the end face of the clamp base 1 around the middle clamping station 2, and the bottom of each clamping cylinder 3 bearing seat 4 has a sliding block 41 matched with the annular guide rail 11, and the bearing seat 4 is slidably mounted on the guide rail through the sliding block 41, which helps to ensure that the bearing seat 4 can move smoothly along the track to accurately adjust the position of each clamping cylinder 3 to clamp different shapes of objects to be clamped and detected.

[0020] As shown, Fig. 2 The locking assembly 5 of the embodiment includes a locking groove 51 opened around the side edge of the clamp base 1, a T-shaped bolt 52 arranged in the locking groove 51, a clamping piece 53 arranged on the side edge of the clamp base 1 and fixedly connected with the bearing seat 4 at one end, and a tightening member 54. The T-shaped bolt 52 includes a clamping plate 521 located in the locking groove 51 and a threaded column 522 extending out of the locking groove 51, and the tightening member 54 is threadedly connected with the threaded column 522. Specifically, the locking groove 51 opened on the side edge of the clamp base 1 is a slot for accommodating and fixing the T-shaped bolt 52, which is designed to have a certain depth and width and a T-shaped cross section to ensure that the T-shaped bolt 52 can be stably slid or positioned therein. The T-shaped bolt 52 is composed of the clamping plate 521 and the threaded column 522, wherein the clamping plate 521 is located in the locking groove 51 and has an arc shape matching the locking groove 51 to fit the inner wall of the locking groove 51, and the fitting surface has friction lines. The clamping piece 53 is fixed at one end of the bearing seat 4 and has a shape matching the side edge of the clamp base 1 for clamping with the clamping plate 521. The tightening member 54 is threadedly connected with the threaded column 522, and when the user rotates the tightening member 54, the threaded column 522 is pulled, and the clamping plate 521 of the T-shaped bolt 52 gradually approaches the clamping piece 53 and the side edge of the clamp base 1 in the locking groove 51, and then the two are locked together to prevent the clamping cylinder 3 from moving when working.

Specifically, the arrangement of the rubber contact piece 31 can effectively protect the surface of the product to be detected from mechanical damage. When the end of the telescopic rod of the clamping cylinder 3 contacts the product, the softness and elasticity of the rubber material can absorb the impact force, thereby avoiding scratches or indentations on the product caused by direct metal contact.

[0022] Further, and including a control system for receiving external signals to start or stop the operation of each of the clamping cylinders 3. Specifically, the control system is mainly responsible for receiving external signals, and according to the signal to start or stop the operation of the cylinder. The control system will usually integrate sensors, switches, PLCs (programmable logic controllers), solenoid valves and other components to achieve accurate control of the cylinder. According to the number of clamping surfaces of the clamped object, the same number of clamping cylinders 3 can be controlled to work.

[0023] In summary, the beneficial effects of the embodiment are: the embodiment drives the pistons of the plurality of clamping cylinders 3 driven by the control system to generate uniform clamping force, ensuring the position of the product to be detected in the clamping station 2 is stable. Avoid the problems of uneven force and insecure clamping that may be caused by traditional mechanical clamping. The carrier seat 4 can slide on the annular guide rail 11 on the clamp base 1, so that the position of the clamping cylinder 3 can be flexibly adjusted according to the shape of the product to be detected. It can adapt to various shapes of products to be detected, especially for irregularly shaped products with complex outer walls, it can accurately position and clamp. Even for irregularly shaped products, the clamp can effectively clamp, avoiding the problem of insecure clamping or misalignment caused by irregular shape. The locking assembly 5 cooperates with the clamping piece 53 through the T-shaped bolt 52, which ensures that the clamping cylinder 3 can be stably fixed at the specified position after adjustment. By rotating the tightening member 54, the T-shaped bolt 52 is tightened, thereby pressing the clamping piece 53 to firmly fix the clamping cylinder 3, avoiding unstable clamp position caused by vibration or external interference, thereby ensuring detection accuracy and consistency. The telescopic rod end of each clamping cylinder 3 is provided with a detachable rubber contact piece 31, which can effectively prevent mechanical damage to the surface of the product to be detected during clamping.
