[0011] Please see Figures 1 to 8 The brake caliper clamping device provided in this embodiment includes a first clamping part 100, a second clamping part 200, a connector 300, and a quick-change connector 400. The first clamping part 100 includes a first mounting base 110, a telescopic device 120, and a support claw 130; The telescopic device 120 is fixedly connected to the first mounting base 110. The output ends of the telescopic device 120 are symmetrically arranged on both sides of the first mounting base 110. The support claw 130 is fixedly connected to the output end of the telescopic device 120 and is slidably connected to the first mounting base 110. The second clamping part 200 includes a second mounting base 210, a gripper 220, and a lifting device 230; The lifting device 230 is fixedly connected to the second mounting base 210, the gripper 220 is fixedly connected to the output end of the lifting device 230, and the gripper 220 is slidably connected to the second mounting base 210. The two ends of the connector 300 are fixedly connected to the first mounting base 110 and the second mounting base 210 respectively, and the quick-connect connector 400 is fixedly connected to the first mounting base 110 or the second mounting base 210.
[0012] In practice: The first clamping part 100 can clamp the brake pad support of the brake caliper, including a first mounting base 110, a telescopic device 120, and a support claw 130. The telescopic device 120 is fixedly connected to the first mounting base 110. The telescopic device 120 is preferably a telescopic cylinder, which is pneumatic, electric, or hydraulic. The telescopic cylinder is a double-headed telescopic cylinder, or a combination of two or four telescopic cylinders. The output ends of the telescopic cylinder are symmetrically arranged on both sides of the first mounting base 110. The support claw 130 is fixedly connected to the output end of the telescopic device 120. The telescopic device 120 synchronously drives the support claws 130 on both sides to extend or retract. In order to ensure the extension effect of the support claw 130, guide holes 115 are provided on both sides of the first mounting base 110. One or two guide blocks are provided on the side of the support claw 130 facing the first mounting base 110, and the guide blocks are located in the guide holes 115. When the first clamping part 100 is working, the telescopic device 120 drives the support claws 130 on both sides of the first mounting base 110 to move outward until they abut against the inner wall of the brake caliper pad support, thereby fixing the brake caliper pad support. The support claws 130 are made of materials such as stainless steel, and the support surface of the support claws 130 that contacts the pad support is fitted with rubber or plastic pads to avoid damage to the surface of the brake caliper.
[0013] The first clamping part 100 and the second clamping part 200 are fixedly connected by a connector 300, which clamps and fixes the brake pad support and mounting plate of the brake caliper, respectively. A quick-change connector 400 is provided on the first clamping part 100, and the brake caliper clamping device is connected to the robot through the quick-change connector 400.
[0014] The second clamping part 200 includes a second mounting base 210, a gripper 220, and a lifting device 230. The lifting device 230 is preferably a telescopic cylinder, and can be pneumatic, electric, or hydraulically operated. The second mounting base 210 is symmetrical, with a through hole in its center. The lifting device 230 is mounted on one side of the second mounting base 210, and its output end extends through the through hole to the other side of the second mounting base 210. Downward-extending fixing plates with guide grooves are provided on both sides of the second mounting base 210. The gripper 220 is located on the side of the second mounting base 210 away from the lifting device 230. A hook 226 is connected to the base 225 of the gripper 220 via a connecting beam 2255 located within the guide groove. Under the action of the lifting device 230, the gripper 220 moves up and down along the guide groove. The hook 226 includes a fixed plate 2265 and side claws 2266. The side claws 2266 have an inwardly extending structure, and each hook 226 includes two side claws 2266. The side claws 2266 are located inside the fixed plate 2265 and at both ends of the fixed plate 2265. The use of two side claws 2266 can better match the structure of the brake caliper mounting plate. When the robot drives the second gripping part 200 to grip the brake caliper, one of the side claws 2266 passes through the notch on the side of the mounting plate from top to bottom. Then, the robot drives the second gripping part 200 to move laterally, so that all the side claws 2266 move to directly below the mounting plate. The lifting device 230 drives the gripper 220 to move upward until the side claws 2266 and the second mounting base 210 abut against the bottom and top of the mounting plate, respectively, thereby achieving the clamping and fixing of the brake caliper mounting plate.
[0015] In actual operation, the first clamping part 100 and the second clamping part 200 are used in conjunction. During operation, using the brake caliper mounting plate as the mounting reference, the robot moves the second clamping part 200 of the transfer assembly to the brake caliper mounting plate side, aligns it with the entry position of the mounting plate, and drives the second clamping part 200 to move towards the mounting plate. After the movement reaches the preset displacement (the side claw 2266 moves to below the mounting plate), the robot pauses its vertical movement and instead drives the transfer assembly to move along the front-back direction of the mounting plate (the first clamping part 100 faces the brake pad support) until the support claw 130 of the first clamping part 100 aligns with the caliper. The telescopic cylinders of the first clamping part 100 and the second clamping part 200 begin to operate. The gripper 220 of the second clamping part 200 moves upward along the mounting plate under the action of the telescopic cylinder, cooperating with the second mounting seat 210 to clamp the mounting plate. The support claw 130 of the first clamping part 100 moves outward under the action of the telescopic cylinder, supporting the brake pad support. Both the first clamping part 100 and the second clamping part 200 have moved into position. The entire clamp and brake caliper form a stable whole. The robot drives the brake caliper to complete a series of movements, ensuring that the brake caliper can be accurately moved to the designated position.
[0016] The first and second clamping parts of the aforementioned brake caliper gripping device are fixedly connected by a connector, allowing them to work together to simultaneously clamp the brake caliper at the brake pad support and mounting plate positions. When the telescopic device of the first clamping part is activated, it drives the support claw to move synchronously inward or outward. When moving outward, it abuts against the brake pad support, thus clamping it. When the second clamping part is activated, the lifting device drives the steering gear to move upward or downward. When moving upward, the claw clamps the mounting plate against the second mounting seat, thus fixing the mounting plate. Combined with quick-connect couplings on the first or second mounting seat, it can be integrated with a robot to achieve automatic gripping and transfer of the brake caliper by the robot.
[0017] As one possible implementation, guide holes 115 are provided on both sides of the first mounting base 110, and a guide plate (not shown in the figure) is provided on the side of the support claw 130 facing the first mounting base 110. The guide plate is slidably connected to the guide hole 115.
[0018] The guide plate on the support claw 130 is connected to the guide hole 115 on the first mounting base 110, which provides guidance for the movement of the support claw 130 and ensures the fixing effect of the support claw 130 on the brake pad support.
[0019] As one possible implementation, a protective pad is provided on the side of the support claw 130 away from the first mounting base 110.
[0020] The protective pad is made of rubber or plastic and reduces damage to the brake pad when the support claw 130 contacts the brake pad support.
[0021] As one possible implementation, the gripper 220 includes a base 225 and a hook 226; the base 225 is fixedly connected to the output end of the lifting device 230, and connecting beams 2255 are provided on both sides of the base 225, and the hook 226 is fixedly connected to the connecting beams 2255. The second mounting base 210 has guide grooves on both sides, and the connecting beam 2255 is located in the guide grooves.
[0022] Furthermore, the hook 226 includes a fixed plate 2265 and side claws 2266; the fixed plate 2265 is fixedly connected to the connecting beam 2255, and the side claws 2266 are arranged on both sides of the fixed plate 2265 and extend inward.
[0023] The base 225 of the gripper 220 is connected to the output end of the lifting device 230, allowing it to move downwards or upwards under the action of the lifting device 230. The side grippers 2266 abut against the lower surface of the mounting plate when gripping it, and abut against the upper surface of the mounting plate when fixing it. The side grippers 2266 and the second mounting plate 210 clamp and fix the mounting plate in both vertical and horizontal directions. The guide grooves, in conjunction with the connecting beams 2255 on both sides of the base 225, provide guidance for the lifting and lowering of the gripper 220, ensuring the stability of the second gripping part 200 when gripping the mounting plate.
[0024] In the description of the above embodiments, specific features, structures, materials, or characteristics may be combined in any suitable manner in one or more embodiments or examples.
[0025] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
