Description

Technical Field

[0001] The utility model relates to the technical field of production equipment for motorcycle or tram accessories, in particular to an integrated machine for brake caliper detection and shock absorber vacuum oil injection. Background Technique

[0002] A brake caliper can also be called a brake cylinder. There are pistons inside the caliper. The function of the caliper is to push the brake pads to clamp the brake disc, so as to decelerate the vehicle. After the brake pads clamp the brake disc, kinetic energy can be converted into heat energy. The braking system is an important system in an automobile, which is related to the driving stability and safety of the vehicle. At present, each manufacturer simulates the working state of the caliper through airtightness detection and air charging and discharging detection to judge whether the product is qualified.

[0003] Shock absorbers are widely used in automobiles or motorcycles, etc., to buffer the vibration between the frame and the body, so as to improve the ride comfort of the vehicle. Before the shock absorber is assembled, it needs to be leak-tested first. After the test is completed and it is determined that the shock absorber has good sealing performance, oil needs to be injected into it at the oil injection port of the shock absorber. The common oil injection method is vacuum oil injection.

[0004] At present, current manufacturers need to match different proprietary equipment for the above two detection processes and cannot share them. This not only increases the production cost, but also increases the process positions with multiple pieces of equipment, wasting manpower and floor space. In view of the above technical problems, the inventor specifically designed an integrated machine for brake caliper detection and shock absorber vacuum oil injection, combining the two processes into one piece of equipment for sharing.

[0030] The control principle of the present utility model when detecting the working state of the brake caliper is as follows:

When the positive pressure air source 2 supplies air pressure, the detection switching valve 6 is electrified, the AP channel of the detection switching valve 6 is opened, the pressure maintaining valve 14 is opened, the positive pressure passes through, the positive pressure enters the inside of the caliper, and the caliper piston is pushed out to achieve the clamping state of the caliper;

[0032] 2. When the positive pressure air source 2 stops supplying, the vacuum pump 1 works, the detection vacuum valve 15 is opened, the detection switching valve 6 is de-energized, the PR channel of the detection switching valve 6 is opened, the pressure maintaining valve 14 is opened, the negative pressure passes through, the air pressure inside the caliper is pumped out, the inside of the caliper is in negative pressure, and the piston retracts to achieve the loosening state of the caliper.

[0037] 1. The vacuum pump 1 works, the vacuum pumping valve 16 is opened, the air in the oil injection pipeline 7 and the inside of the shock absorber is pumped out, so that the inside of the shock absorber is in a negative pressure state.

[0038] 2. When the vacuum pump 1 stops working, the oil fluid circulation valve 12 works and is opened, the hydraulic oil inside the small oil cylinder 11 enters the large oil cylinder 9 through the oil fluid circulation valve 12, and drives the air inside the oil injection pipeline 7 into the large oil cylinder 9.

[0039] 3. The positive pressure air source 2 supplies air pressure to enter, the oil injection valve 17 is opened, the RA channel of the oil injection switching valve 13 is opened, and the positive pressure pushes the hydraulic oil inside the large oil cylinder 9 into the inside of the shock absorber.
