Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of brake production, and in particular to an automatic assembling device for a noise-reducing brake. BACKGROUND

[0002] With the rapid development of modern industry, the automobile industry has also entered a steady growth period of connotative development, and the improvement of vehicle quality has become the mainstream of development. Brake noise, body vibration and engine noise are among the most important comprehensive indicators for measuring the quality of automobile design and manufacturing. Brake vibration and noise are caused by vibration of the brake during operation. When the automobile brakes, not only does the front axle load increase and the rear axle load decrease, increasing the vibration of the vehicle, but both disc and drum brakes will produce vibration and cause serious noise. Brake noise and vibration exist widely in various vehicles, not only seriously affecting the braking performance and driving comfort of the automobile, but also causing noise pollution in the city.

[0003] The patent document with the patent number CN216343575U discloses a brake noise reduction structure and a brake. The brake noise reduction structure includes a shaft sleeve, a friction disc and an elastic member. The friction disc is sleeved on the outer periphery of the shaft sleeve and can rotate with the shaft sleeve. The friction disc has a mounting portion. The elastic member is arranged on the mounting portion. The elastic member has an abutting portion that can abut against the outer periphery surface of the shaft sleeve in the radial direction of the friction disc. The elastic member has a pre-tightening force that causes the abutting portion to approach the center of the friction disc. The brake includes the above-mentioned brake noise reduction structure. The brake noise reduction structure and the brake provided by the utility model prevent the friction force between the shaft sleeve and the friction disc from increasing, which facilitates installation. The stable cooperation between the shaft sleeve and the friction disc achieves noise reduction.

[0004] However, in actual production process, the inventor found that the existing brake assembling device has the following defects: manual assistance is required for assembly, the degree of automation is low, the production cost is high, and the assembly precision is insufficient. At the same time, the structure design of the existing brake is unreasonable. Not only does the local noise reduction result in poor noise reduction effect, but also the noise reduction structure is prone to wear and tear after long-term use, which reduces the noise reduction effect and service life. Moreover, the overall assembly sequence design is unreasonable, which leads to low assembly efficiency and cannot guarantee product quality, resulting in low yield. SUMMARY

[0059] In detail, in use, after the first telescopic rod 521 is extended until the support block 421 supports the outer side of the elastic sheet 13, the clamping plates 523 are closed and clamped to the two ends of the elastic sheet 13, at this time, the second sensor detects the distance between the two clamping plates 523, and detects whether the shape of the elastic sheet 13 is qualified for the first time, then in the process of shortening the first telescopic rod 521 to pull the elastic sheet 13 away from the top die 513, the top die 513 forces the elastic sheet 13 to open, the first sensor detects the maximum pulling force of the first telescopic rod 521, and further reflects whether the elastic force of the elastic sheet 13 is qualified, the second sensor detects the distance between the two clamping plates 523 when the elastic sheet 13 is opened to the maximum, and detects whether the shape of the elastic sheet 13 is qualified for the second time, the detection accuracy is high, and subsequent rework and product quality problems are avoided, finally, after rotating and moving the first telescopic rod 521 to deliver the elastic sheet 13 to the outer side of the shaft sleeve 12, the first telescopic rod 521 is extended to clamp the elastic sheet 13 into the mounting seat 121 of the shaft sleeve 12.

[0079] In detail, the rubber ring conveyor 61 conveys the gasket 14 outside the first supporting rods 62 and positions the gasket 14 by the supporting plate 63, then the first supporting rods 62 cooperate with the supporting plate 63 to position and expand the gasket 14, and cooperate with the second supporting rods 64 to further expand the gasket 14, then the second supporting rods 64 are moved out of the gasket 14 after the second telescopic rod 41 is inserted into the gasket 14, and the gasket 14 is forced to move until being positioned in the annular groove 122 under the guidance of the guide groove 131 of the elastic sheet 13, and then the first supporting rods 62 are moved out of the gasket 14, so that the gasket 14 is positioned and mounted in the guide groove 131 and the annular groove 122.

[0080] It should be noted that the gasket 14 is a rubber over-latex gasket, and the rubber ring conveyor 61 used for conveying the gasket 14 is a prior art, and the gasket 14 itself and the mounting method are prior arts, which are not described in detail here.

[0081] Working process:

[0082] Firstly, the first conveying assembly 23 cooperates with the first supporting assembly 22 to position and support the friction disc 11 on the supporting table 21, and after the second conveying assembly 44 cooperates with the positioning assembly 43 to position and support the shaft sleeve 12 on the supporting table 21, the filling mechanism 3 fills the first elastic member 16 and the top block 15 into the mounting groove 111 of the friction disc 11 in sequence, and the second supporting assembly 42 positions and supports the positioned shaft sleeve 12 on the second telescopic rod 41.

[0083] Then, the forming assembly 51 forms the elastic sheet 13, and after the first assembling assembly 52 cooperates with the detection mechanism to take down the elastic sheet 13 from the forming assembly 51 and detects the elastic sheet 13, the first assembling assembly 52 positions and mounts the elastic sheet 13 on the shaft sleeve 12 supported by the second supporting assembly 42 on the second telescopic rod 41.

[0084] Then, the first support rod 62 cooperates with the support plate 63 to position and expand the gasket 14, and after the second support rod 64 further expands the gasket 14, the second telescopic rod 41 extends into the gasket 14, the second support rod 64 first moves out of the gasket 14, and under the guidance of the guide groove 131 on the elastic sheet 13, the gasket 14 is forced to move until it is positioned in the annular groove 122, thereby moving the first support rod 62 out of the gasket 14, the gasket 14 is installed into the guide groove 131 and the annular groove 122, and the elastic sheet 13 is limited to avoid large dislocation movement;

[0085] Finally, the second telescopic rod 41 extends into the friction disc 11, and under the mutual extrusion of the elastic sheet 13 and the friction disc 11, the shaft sleeve 12 is positioned and centered, avoiding the gasket 14 from being severely cut during assembly between the shaft sleeve 12 and the friction disc 11, until the first elastic member 16 forces the top block 15 to top into the guide groove 131 of the elastic sheet 13, thereby positioning and assembling the brake 1.
