Description

Technical Field

[0001] The utility model relates to the technical field of automobile suspension, in particular to a clamping and positioning device for assembling piston caliper parts. Background Art

[0002] In modern automotive manufacturing, particularly in the areas of suspension and safety braking, the assembly process of the brake caliper assembly plays a crucial role. As the core actuator in the braking system, the brake caliper is responsible for quickly and effectively generating braking force when the driver depresses the brake pedal through close contact with the brake disc, ensuring safe and smooth deceleration or stopping of the vehicle. Therefore, the assembly precision and efficiency of the brake caliper are directly related to the braking performance and driving safety of the entire vehicle.

[0003] However, the current brake caliper assembly process, especially in the critical step of bolt tightening, is quite cumbersome and inefficient.

After the bolt tightening is completed, the entire piston caliper is visually inspected and functionally tested to ensure that the assembly quality meets the requirements.

[0029] Please refer to Figures 3 to 7 As an embodiment of the present invention, the positioning mechanism 9 includes a connecting plate 901, wherein the connecting plate 901 is fixedly connected to the front end of the support seat 8; a movable arm 902 is provided at the front end of the connecting plate 901, wherein the movable arm 902 is a bent structure; one end of the movable arm 902 is rotatably connected to the connecting plate 901 through a seat bearing 903, wherein the other end of the movable arm 902 extends above the support seat 8 and is fixedly installed with a positioning block 904; a bolt locking assembly 905 is provided at the upper end of the connecting plate 901, wherein the bolt locking assembly 905 is arranged on one side of the movable arm 902; the bolt locking assembly 905 includes a shell 9051, wherein the lower end of the shell 9051 is fixedly connected to the connecting plate 901; a latch shaft 9052 is installed in the shell 9051, wherein a through hole 906 adapted to the latch shaft 9052 is opened on the movable arm 902, and the latch shaft 9052 passes through the through hole 906 on the movable arm 902 and extends outward.

[0030] In the above-described scheme, the connecting plate 901 is firmly fixed to the front end of the support seat 8, and the connecting plate 901 ensures the stability and accuracy of the positioning mechanism 9 in the overall structure; the movable arm 902 is the key movable component in the positioning mechanism 9, wherein the movable arm 902 is designed as a bending structure to adapt to different assembly requirements, and one end of the movable arm 902 is rotatably connected to the connecting plate 901 through a seat bearing 903. This design allows the movable arm 902 to rotate freely within a certain range to adapt to caliper tooling 11 of different shapes and sizes; the other end of the movable arm 902 extends to above the support seat 8, and a positioning stop block 904 is fixedly installed at this end, wherein the positioning stop block 904 is a key component to ensure the precise positioning of the caliper tooling 11, and the shape and size of the positioning stop block 904 need to be designed according to the specific requirements of the caliper tooling 11.

[0031] Furthermore, the pull-bolt locking assembly 905 is located at the upper end of the connecting plate 901 and is arranged on one side of the movable arm 902, wherein the pull-bolt locking assembly 905 includes a shell 9051, the lower end of which is fixedly connected to the connecting plate 901 to form a stable installation base; a latch shaft 9052 is installed in the shell 9051, and the latch shaft 9052 is a key component for locking the position of the movable arm 902; a through hole 906 that is compatible with the latch shaft 9052 is pre-opened on the movable arm 902. When the movable arm 902 is rotated to the desired position, the latch shaft 9052 can pass through the through hole 906 on the movable arm 902 and extend outward, thereby locking the position of the movable arm 902; the user can control the movement of the latch shaft 9052 by operating the pull-bolt locking assembly 905 (such as pulling or rotating the pull-bolt), thereby realizing the locking and unlocking of the movable arm 902. This design makes the operation of the positioning mechanism 9 simple and quick, and improves the assembly efficiency.

[0032] Before assembly begins, the angle of the movable arm 902 is rotated according to the specific requirements of the caliper tooling 11, so that the positioning block 904 on the movable arm 902 can abut against the limit block 1104 on the caliper tooling 11; when the movable arm 902 is adjusted into position, the bolt locking assembly 905 is operated to insert the pin shaft 9052 into the through hole 906 on the movable arm 902 to lock the position of the movable arm 902. At this time, the positioning block 904 firmly abuts against the limit block 1104 on the caliper tooling 11 to achieve precise positioning; during the assembly process, the positioning mechanism 9 remains locked to ensure that the caliper tooling 11 will not move or deflect due to external force.

[0034] In the above-mentioned solution, the latch positioning block 907 is located on the side of the movable arm 902 away from the housing 9051, ensuring that it can provide stable support and positioning when the latch shaft 9052 locks the movable arm 902; the lower end of the latch positioning block 907 is fixedly connected to the connecting plate 901, and this fixing method usually adopts bolts, welding or other mechanical connections to ensure that the latch positioning block 907 will not loosen or fall off during assembly and use; a positioning hole 908 is opened on the latch positioning block 907, and the shape, size and position of the positioning hole 908 are adapted to the top of the latch shaft 9052. This design makes the latch shaft 9052 firmly fixed when inserted into the movable arm 9 02 through hole 906, it can be further inserted into the positioning hole 908 of the latch positioning block 907, thereby achieving a double locking effect; the use of the latch positioning block 907 in conjunction with the latch shaft 9052 can ensure that the movable arm 902 maintains a stable position and angle in the locked state, thereby improving the positioning accuracy of the caliper tooling 11; the latch positioning block 907 provides additional support and positioning points for the latch shaft 9052, thereby enhancing the overall stability of the positioning mechanism 9 and preventing displacement or loosening due to external force during assembly; through the double locking design, the locking and unlocking operation process of the movable arm 902 is simplified, and the assembly efficiency is improved.

[0035] Furthermore, before assembly begins, the pin positioning block 907 has been firmly mounted on the connecting plate 901, and the positioning hole 908 thereon has been checked for compatibility with the top end of the pin shaft 9052 to ensure that the two can cooperate smoothly; according to the specific requirements of the caliper tooling 11, the position and angle of the movable arm 902 are adjusted so that the positioning block 904 can abut and cooperate with the limit block 1104 on the caliper tooling 11; when the movable arm 902 is adjusted into place, the pin shaft 9052 is inserted into the through hole 906 on the movable arm 902 by operating the pull bolt locking assembly 905. As the pin shaft 9052 continues to advance, its top end will enter the positioning hole 908 of the pin positioning block 907 to achieve double locking; after the pin shaft 9052 is fully inserted into the positioning hole 908, the movable arm 902 is firmly locked in the desired position; at this time, the positioning block 904 is tightly against the caliper tooling 11 to achieve precise positioning and fixation.

The position and angle of the movable arm 902 are adjusted, and the latch shaft 9052 is inserted into the through hole 906 of the movable arm 902 through the bolt locking assembly 905. As the latch shaft 9052 moves, the limit lever 9055 slides in the limit slot 9054 until it reaches the predetermined position and is locked into the corresponding position of the limit slot 9054. At this time, the latch shaft 9052 and the movable arm 902 are locked in the predetermined position; when the position of the movable arm 902 needs to be adjusted, the bolt locking assembly 905 can be reversed to unlock the latch shaft 9052 and the movable arm 902. At this time, the limit lever 9055 is disengaged from the limit slot 9054, and the latch shaft 9052 can move freely, thereby realizing the adjustment of the movable arm 902.
