[0002] The automotive brake caliper bracket is an important part of the automotive braking system and is used to install hydraulic pistons and brake pads. During the driving of the vehicle, the brake disc rotates with the wheel, and the brake caliper bracket remains stationary. When braking, the brake pads installed on the brake caliper bracket clamp the brake disc under the push of the hydraulic piston to complete the braking function. The automotive brake caliper bracket plays an irreplaceable role in the entire vehicle.

[0003] In the prior art, when manufacturing automotive brake caliper brackets, positioning fixtures are usually required to fix the brake caliper brackets on the CNC machine tools for machining. During the above fixing process, the automotive brake caliper brackets need to be transferred from the storage station to the positioning fixtures by manual handling. Since the machining process often involves multi-stage machining and the automotive brake caliper brackets need to be transferred between different CNC machine tools, the manual handling method does not meet the production requirements, and it has the problems of high labor intensity of workers and easy occurrence of safety accidents.

[0004] The inventor's search found that there is currently no fixture for clamping automotive brake caliper brackets to transfer them from the storage station to the positioning fixtures, or to transfer them from one positioning fixture to another positioning fixture. Summary of the Utility Model

[0005] Aiming at the deficiencies of the prior art, the purpose of the present utility model is to provide a fixture for clamping automotive brake caliper brackets, which can transfer the automotive brake caliper brackets from the storage station to the positioning fixtures, or from one positioning fixture to another positioning fixture with the assistance of a manipulator; the present utility model solves the problems of high labor intensity of workers and easy occurrence of safety accidents.

[0006] The above technical purpose of the present utility model is achieved through the following technical solutions:

[0007] A fixture for clamping automotive brake caliper brackets includes a mounting frame. Claw assemblies for actively clamping automotive brake caliper brackets are arranged at the four end corners on one side surface of the mounting frame, and a connection head for connecting with a manipulator is arranged on the other side surface of the mounting frame.

[0008] Optionally, the jaw assembly includes a first connecting seat and a second connecting seat; a hydraulic cylinder is provided on the first connecting seat, and a first clamping plate for actively pressing against the outer side of the automotive brake caliper bracket is arranged on the movable end of the hydraulic cylinder; at least one linear bearing for preventing the first clamping plate from rotating is provided on the first connecting seat, and the movable end of the linear bearing is fixedly connected to the first clamping plate; a second clamping plate for actively pressing against the inner side of the automotive brake caliper bracket and adapted to the first clamping plate to form a gripper for clamping the automotive brake caliper bracket is arranged on the second connecting seat; both the first connecting seat and the second connecting seat are fixedly connected to the mounting bracket.

[0009] Optionally, a positioning cone for actively inserting into the mounting hole on the automotive brake caliper bracket to achieve a positioning effect is arranged on the first clamping plate.

[0010] Optionally, a buffer block for preventing dents on the automotive brake caliper bracket during the clamping process is arranged on the second clamping plate.

[0011] Optionally, a universal joint air nozzle for cleaning foreign objects adhering to the buffer block is arranged on the second clamping plate.

[0012] Optionally, a proximity switch for adjusting the sliding stroke of its movable end and thus adjusting the clamping force of the first clamping block and the second clamping block on the automotive brake caliper bracket is arranged on the hydraulic cylinder.

[0013] Optionally, a positioning pin is arranged on the mounting bracket to facilitate the positioning and calibration of the mounting bracket by the manipulator.

[0025] The present utility model will be described in detail below with reference to the accompanying drawings and embodiments.

[0026] The present utility model provides a fixture for clamping an automotive brake caliper bracket, as Figure 1-6 shown, which includes a mounting frame 1. Claw assemblies 2 for actively clamping an automotive brake caliper bracket 3 are provided at the four end corners of one side surface of the mounting frame 1, and a connector 11 for connecting with a manipulator is provided on the other side surface of the mounting frame 1.

[0027] In this embodiment, a claw assembly 2 is fixedly installed at the four end corners of the bottom surface of the mounting frame 1 by existing means such as screws and welding; among them, the two claw assemblies 2 located at the left end or the right end of the mounting frame 1 are arranged in parallel, and both clamp or release different automotive brake caliper brackets 3 simultaneously; the two claw assemblies 2 located at the upper side or the lower end of the mounting frame 1 are arranged in mirror symmetry, and both can clamp different automotive brake caliper brackets 3 simultaneously or non - simultaneously. A connector 11 is fixedly installed at the center position of the top surface of the mounting frame 1 by existing means such as screws and welding.

[0028] In one application scenario, the manipulator drives the fixture to move to the storage station through the connector 11. Then, the two jaw assemblies 2 located at the left end of the mounting frame 1 respectively grip an automotive brake caliper bracket 3. Then, the manipulator moves to the first CNC machine tool according to a preset trajectory. At this time, the two jaw assemblies 2 located at the right end of the mounting frame 1 respectively grip the processed automotive brake caliper bracket 3 on the positioning fixture and leave the positioning fixture. The manipulator rotates 180 degrees and transfers the two unprocessed automotive brake caliper brackets 3 located at the left end of the mounting frame 1 to the positioning fixture for processing. Then, the manipulator moves to the second CNC machine tool again according to the preset trajectory. At this time, the two jaw assemblies 2 located at the left end of the mounting frame 1 respectively grip the processed automotive brake caliper bracket 3 on the positioning fixture on the second CNC machine tool and leave the positioning fixture. The manipulator rotates 180 degrees and transfers the automotive brake caliper bracket 3 that has been processed by the first CNC machine tool and is located at the right end of the mounting frame 1 to the positioning fixture for processing. Then, the manipulator moves to the finished product storage station again according to the preset trajectory, and the two jaw assemblies 2 located at the left end of the mounting frame 1 respectively release the automotive brake caliper bracket 3 that has been processed by the second CNC machine tool. Then, the manipulator moves to the storage station again according to the preset trajectory to perform the next cycle.

[0029] In the present utility model, a jaw assembly 2 is provided at each of the four end corners of the mounting frame 1, so that the jaw assembly 2 can actively grip the automotive brake caliper bracket 3 and is connected to the manipulator through the connector 11. Under the multi-directional movement of the manipulator, the automotive brake caliper bracket 3 is transferred from the storage station to the positioning fixture, or transferred from one positioning fixture to another positioning fixture. The transfer process does not require the participation of workers, solving the problems of high labor intensity of workers and easy occurrence of safety accidents, and having the advantage of high safety factor.

[0030] Furthermore, the jaw assembly 2 includes a first connecting seat 21 and a second connecting seat 22; a hydraulic cylinder 23 is provided on the first connecting seat 21, and a first clamping plate 24 for actively pressing against the outer side of the automotive brake caliper bracket 3 is provided on the movable end of the hydraulic cylinder 23; at least one linear bearing 25 for preventing the first clamping plate 24 from rotating is provided on the first connecting seat 21, and the movable end of the linear bearing 25 is fixedly connected to the first clamping plate 24; a second clamping plate 26 for actively pressing against the inner side of the automotive brake caliper bracket 3 and adapted to the first clamping plate 24 to form a gripper for gripping the automotive brake caliper bracket 3 is provided on the second connecting seat 22; both the first connecting seat 21 and the second connecting seat 22 are fixedly connected to the mounting frame 1.

[0031] As Figure 3-6As shown, the first connecting seat 21 and the second connecting seat 22 are respectively fixedly installed on the outer side and the inner side of the mounting bracket 1 (the inner side is closer to the center of the mounting bracket 1) by screws. A hydraulic cylinder 23 and two linear bearings 25 are fixedly installed on the first connecting seat 21 by screws. The two linear bearings 25 are respectively located on both sides of the hydraulic cylinder 23 and are symmetric about it. The movable ends of the hydraulic cylinder 23 and the two linear bearings 25 are fixedly connected to the first clamping plate 24 by threads, thereby driving the first clamping plate 24 to slide reciprocally in the direction of the second clamping plate 26. The first clamping plate 24 and the second clamping plate 26 are arranged in parallel to clamp the automotive brake caliper bracket 3 movably.

[0032] By installing at least one linear bearing 25 on the first connecting seat 21, the jaw assembly 2 increases the number of force application points of the first clamping plate 24, thereby improving the stability of the automotive brake caliper bracket 3 during the clamping and transfer processes, preventing it from falling due to the rotation of the first clamping plate 24 during the clamping process, and reducing the risk of it colliding with the CNC machine tool.

[0033] Furthermore, a positioning cone 27 is provided on the first clamping plate 24 for movably inserting into the mounting hole 31 on the automotive brake caliper bracket 3 to achieve a positioning effect.

[0034] As Figure 3-6 shown, the two positioning cones 27 are both installed on the left and right ends of the first clamping plate 24 by threaded connection, and their specific positions correspond one-to-one to the mounting holes 31 on the automotive brake caliper bracket 3. Inserting the positioning cone 27 into the mounting hole 31 facilitates the quick positioning and clamping of the automotive brake caliper bracket 3 on the one hand, and on the other hand, plays the role of a "pin", preventing the automotive brake caliper bracket 3 from falling off the first clamping plate 24 and the second clamping plate 26 during the transfer process, and reducing the risk of it colliding with the CNC machine tool.

[0035] Furthermore, a buffer block 28 is provided on the second clamping plate 26 to prevent the automotive brake caliper bracket 3 from being dented during the clamping process.

[0036] As Figure 3-6 shown, the buffer block 28 is made of elastic rubber and is installed on the side of the second clamping plate 26 close to the first clamping plate 24 by screws. It can prevent the second clamping plate 26 or the first clamping plate 24 from squeezing out dents, scratches, etc. on the surface of the automotive brake caliper bracket 3 due to excessive clamping force.

[0037] Furthermore, a universal joint air nozzle 29 is provided on the second clamping plate 26 to clean foreign objects adhering to the buffer block 28.

[0038] As Figure 3-6As shown, two universal joint air nozzles 29 are fixed on the second clamping plate 26 by clamping, and are respectively located at both ends of the buffer block 28. After the universal joint air nozzles 29 are connected to the compressed air pipe, compressed air is regularly blown out to blow away foreign matters adhering to the buffer block 28, preventing dents, bruises, etc. from being extruded on the surface of the automotive brake caliper bracket 3 during the clamping process.

[0039] Furthermore, a proximity switch 231 is provided on the hydraulic cylinder 23 for adjusting the sliding stroke of its movable end, thereby adjusting the clamping force of the first clamping block and the second clamping block on the automotive brake caliper bracket 3.

[0040] As Figure 3-6 shown, the proximity switch 231 is installed in the chute on the hydraulic cylinder 23. When the proximity switch 231 senses that the movable end of the hydraulic cylinder 23 extends to a preset position, it feeds back a signal to the controller, and then controls the hydraulic cylinder 23 not to slide out of the cylinder block through the oil supply pipeline. That is to say, the proximity switch 231 can prevent the clamping force from being too large due to the excessive sliding stroke of the hydraulic cylinder 23, and prevent dents, bruises, etc. from being extruded on the surface of the automotive brake caliper bracket 3 by the second clamping plate 26 or the first clamping plate 24.

[0041] Furthermore, as Figure 1 shown, a positioning pin 12 for facilitating the positioning and calibration of the manipulator to the mounting bracket 1 is provided on the mounting bracket 1 by means of threaded connection, thereby improving the efficiency of the debugger during the debugging process of the manipulator.

[0042] The above are only the preferred embodiments of the present invention. The protection scope of the present invention is not limited to the above embodiments. All technical solutions falling within the idea of the present invention belong to the protection scope of the present invention. It should be pointed out that for those of ordinary skill in the art, several improvements and refinements made without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
