Description

Technical Field

[0001] The utility model relates to the technical field of brake caliper detection, in particular to a drag detection automatic clamping mechanism. Background Technique

[0002] As is well known, after dynamic supercharging, during the piston return process, the brake pads and the brake disc still fit and rub against each other, and the resulting frictional torque is the drag torque, which has a certain impact on fuel consumption and braking noise. Therefore, it is necessary to detect the drag torque of the brake caliper.

[0003] After retrieval, the utility model patent with the Chinese patent publication number CN211042565U discloses a drag detection automatic clamping mechanism, which includes a drag detection tooling and an automatic tightening mechanism installed on the drag detection workbench. The drag detection tooling includes a vertically arranged tooling support plate. A tooling hardening backing plate and a positioning strip are installed behind the tooling support plate. The tooling hardening backing plate fits with the installation surface of the brake caliper bracket. The positioning strip supports the bottom of the brake caliper. The tooling support plate is connected with a locking screw that passes through the installation hole of the brake caliper bracket and locks and fixes the brake caliper. The automatic tightening mechanism includes a tightening gun and a telescopic cylinder. When the automatic tightening mechanism operates normally, the telescopic cylinder and the tightening gun act simultaneously. The tightening gun drives the locking screw in the drag detection tooling assembly to rotate. The telescopic cylinder makes the tightening gun move back and forth through a connecting plate, so as to automatically screw the locking screw into the caliper bracket installation hole to achieve automatic clamping at the drag detection station.

[0004] Although the above technical solution solves the problem of automatic clamping at the drag detection station, in the above technical solution, the brake caliper is fixed by the positioning strip, the locking screw, the positioning block and the tooling support plate. However, the bottom structures and sizes of different brake calipers may be different. Therefore, it is necessary to design and adjust the positioning strip, the locking screw, the positioning block and the tooling support plate for each type of brake caliper to ensure accurate support and positioning, which has a high cost and delays the work efficiency of workers. To solve the above problems, therefore, a drag detection automatic clamping mechanism is needed. Content of the Utility Model

By operating the auxiliary column 15, especially the first handle 23 at its top, the rotating rod 9 can be driven to rotate, and then the clamping blocks 2 move towards each other to clamp the brake caliper. The detachable design of the auxiliary column 15 makes the entire drag detection automatic clamping mechanism more flexible, and it can be disassembled and installed according to different usage scenarios and requirements. Small holes are formed in each clamping block 2, and threaded columns 20 are threadedly connected to the inner walls of the small holes. Rubber pads 21 are fixedly connected to the tops of the threaded columns 20. The function of the threaded column 20 is to rotate through the thread and cooperate with the rubber pad 21 to increase the contact area between the clamping block 2 and the main body 1, preventing rotation during the installation of the drag detection automatic clamping mechanism and affecting the installation efficiency. The material and structural design of the rubber pad 21 make it difficult for the clamping block 2 to rotate during the installation of the drag detection automatic clamping mechanism, thus improving the installation efficiency.

[0053] Working principle:

[0054] When the drag detection automatic clamping mechanism is in use, first place the drag detection automatic clamping mechanism at the required position, and then install the drag detection automatic clamping mechanism on the main body 1. The specific operation is as follows: First, the staff places the clamping block 2 on the main body 1, and then presses the first handle 23 by hand. The movement of the first handle 23 drives the movement of the auxiliary column 15. The movement of the auxiliary column 15 drives the movement of the rotating column 22. The movement of the rotating column 22 drives the movement of the connecting rod 10. At the same time, the movement of the auxiliary column 15 drives the movement of the rubber strip 24, so that the rubber strip 24 contacts the main body 1 to complete the fixation of the main body 1.
