Description

Technical Field

[0001] This utility model relates to the technical field of brake caliper tooling equipment, specifically an auxiliary tooling for assembling brake calipers for electric vehicles (EHB). Background Technology

[0002] An electric vehicle EHB assembly line refers to a production line used to assemble electro-hydraulic braking systems. EHB is a brake-by-wire technology developed from traditional hydraulic braking systems. It uses an electric motor as a power source, replacing the traditional vacuum booster and achieving electronic control of the braking system. This assembly line is specifically used to produce and assemble various components required for EHB systems, including key components such as motors, hydraulic units, and brake calipers. Brake calipers are an important component of the automotive braking system, having functions such as decelerating, stopping, or maintaining a stopped state for moving parts.

[0003] In the prior art, Chinese utility model patent with publication number CN216227846U discloses a brake piston assembly fixture, including a radial drilling machine, with a brake cylinder body fixedly connected to the lower part of the radial drilling machine. A piston hole is formed on the inner side of the brake cylinder body, and a threaded hole is formed on the inner wall of the piston hole. A piston is mounted inside the piston hole. This fixture allows for precise docking of the piston, and its structure is reasonable, simple, and ingenious, fully realizing the rapid and safe assembly of new brake pistons.

[0004] However, the aforementioned device did not effectively remove the dust from the inner wall of the piston hole before installing the brake caliper piston. As a result, the dust remaining inside the brake caliper body and piston during operation exacerbates the wear between the brake caliper piston and the piston hole, affecting the service life of the brake caliper. Therefore, it does not meet the existing requirements. To address this, we propose an auxiliary tooling for assembling the brake caliper of an electric vehicle EHB. Utility Model Content

A filter screen 19 is installed in the middle of the interior of the housing 4. An air pump 18 is installed behind the filter screen 19.

[0023] The clamping mechanism 2 includes a U-shaped plate 201. A first electric push rod 203 is installed on the front end face of the U-shaped plate 201. A clamping plate 202 is fixedly connected to the rear end face of the first electric push rod 203. Rubber pads are installed on opposite sides of the outer surfaces of the clamping plate 202 and the U-shaped plate 201. The bidirectional moving mechanism 7 includes a short shaft. The short shaft is installed on the upper end face of the base 1 through a transverse groove. Threaded rods are installed at both ends of the short shaft. Threaded plates are sleeved on the outer surface of the threaded rods. The clamping mechanism 2 can limit the brake caliper.

[0024] The upper end face of the threaded plate is fixedly connected to the lower end face of the U-shaped plate 201, and the thread directions of the two threaded rods are opposite. A forward and reverse motor is installed on one side of the transverse groove through the motor cavity. The forward and reverse motor is fixedly connected to one end of one of the threaded rods through a coupling. The other end of the other threaded rod is rotatably connected to the inner wall of the transverse groove through a bearing. By controlling the operation of the forward and reverse motors, the threaded rods can be driven to rotate, and the two threaded plates can move simultaneously in the direction of approaching or moving away.

[0025] The output end of the rotary motor 17 is fixedly connected to the upper end face of the rotating shaft 10 via a vertical shaft. An anti-slip pad is fixedly connected to the outer surface of the arc plate 12. The support plate 13 is a strip plate, the partition plate 15 is a circular plate, and the lifting seat 6 is a circular shell with the opening facing downward. The shell 4 and the lifting seat 6 are connected by a connecting pipe. One end of the connecting pipe passes through the lifting seat 6 and extends to the top of the partition plate 15.

[0028] When using the auxiliary tooling for assembling the brake caliper of the EHB electric vehicle, first connect the power supply. Before installing the brake caliper piston, install the brake caliper body on the base 1 using the clamping mechanism 2. Then, insert the piston into the outer side of the rotating shaft 10. Turn on the switch of the second electric push rod 11 so that the four arc-shaped plates 12 can move outward and abut against the inner wall of the piston. Turn on the switch of the hydraulic cylinder 5 so that the lifting seat 6 moves downward, driving the piston down into the piston hole. Turn on the switch of the fan body 16 so that the air blown out by the fan body 16 pushes the sealing plate 1406 away from the inner side of the round hole 1405. The spring 1402 is compressed, and the air is blocked through the gap between the sealing plate 1406 and the air outlet 9. The dust inside the piston hole on the brake caliper body is blown out. After the dust is blown out, the air pump 18 can be turned on to draw the blown dust into the inside of the housing 4 through the air inlet 8 and connecting pipe. At the same time, the dustproof mechanism 14 is provided inside the air outlet 9 to prevent dust from entering the lifting seat 6 through the air outlet 9. After the piston hole on the brake caliper body is cleaned, the rotary motor 17 is started. The rotary motor 17 drives the rotating shaft 10 to rotate, thereby realizing the rotational installation of the piston on the brake caliper body. This utility model can perform dust removal treatment by blowing and sucking dust from the piston hole on the brake caliper body, reducing wear between the piston and the piston hole and improving the service life of the brake caliper.
