Description

Technical Field

[0001] This utility model relates to the field of automotive parts processing technology, specifically to a pneumatic clamping and drilling device for brake pads. Background Technology

[0002] Brake pads, also known as brake discs, are key safety components of the braking system in automobiles and other motor vehicles. They convert the vehicle's kinetic energy into heat energy through friction with the brake disc or brake drum, thus slowing the vehicle down and bringing it to a stop. They are generally composed of a steel plate, an adhesive heat insulation layer, and friction materials. They can be divided into disc brake pads and drum brake pads. According to the material, they are classified into asbestos (banned), semi-metallic, low-metallic, NAO, ceramic, etc. They are required to have a suitable coefficient of friction, good wear resistance, stable heat fade, and low noise. There is no fixed standard for replacement cycle, which is affected by factors such as driving habits. You can check the thickness to determine whether it needs to be replaced.

[0003] In the existing technology for drilling brake pads, there are many drawbacks that affect processing efficiency. On the one hand, the processing procedure is cumbersome and has a low degree of automation. It requires the brake pads to be transported to the drilling device and then manually positioned. This not only consumes a lot of manpower, but also makes it difficult to guarantee the accuracy of manual positioning, which is prone to deviation and leads to unstable processing quality. On the other hand, even if some existing technologies use mechanical processing methods, the number of brake pads that can be processed at one time is usually small. If processing efficiency is to be improved, multiple processing heads for drilling are required, resulting in high costs. Utility Model Content

[0004] To overcome the shortcomings of existing technologies, the purpose of this utility model is to provide a pneumatic clamping and drilling device for brake pads. During brake pad drilling, two rotating tables are provided. A second servo motor of the first drive assembly drives the brake pad to rotate synchronously via a first synchronous pulley and a transmission belt. The drilling assembly has two different drilling positions. On one rotating table, the drive assembly with a clamping component rotates the brake pad to complete part of the hole processing in conjunction with drilling. The other rotating table can be clamped or wait. After processing, the brake pad is transferred to the next machine for secondary drilling. The two operations are synchronized to improve efficiency. The drilling assembly also uses a similar multi-transmission connection method to reduce the number of drive devices. After the brake pad is moved to the rotating table, the motor with a baffle pushes it according to a preset trajectory and force to ensure accurate positioning.

[0005] The objective of this utility model is achieved through the following technical solution:

[0006] A pneumatic clamping and drilling device for brake pads includes a frame, brake pads placed on the frame, and slots formed in the brake pads; it also includes a first drive assembly, a second drive assembly, and a screw drive component mounted on the frame and mounted on a first connecting frame. A material handling assembly is mounted on the output end of the screw drive component, a clamping assembly is mounted on the output end of the first drive assembly, and a drilling assembly and a power transmission assembly are mounted on the output end of the second drive assembly. A first servo motor is mounted on the frame, and a straightening plate is mounted on the first servo motor. The screw drive component drives the material handling assembly to move horizontally along a predetermined track, the first drive assembly drives the clamping assembly to rotate on the frame, and the second drive assembly drives the drilling assembly and the power transmission assembly to move horizontally along the predetermined track.

[0007] In one optional embodiment, two rotating slots are provided on the frame, and a rotating disk is rotatably arranged in the rotating slot. A first synchronous pulley is fixedly connected to the lower end of the rotating disk. The first drive assembly includes a fixed frame mounted on the frame, a second servo motor mounted on the fixed frame, and a first transmission belt rotatably connected to the two first synchronous pulleys. The output end of the second servo motor is connected to the first synchronous pulley. The second servo motor is used to drive the first synchronous pulley to rotate. When the first synchronous pulley rotates, the first transmission belt sleeved on it drives the two rotating disks to rotate synchronously.

[0008] In one optional embodiment, the clamping assembly includes a double-headed cylinder mounted on a rotating disk, a pin mounted on the output end of the double-headed cylinder, the pin being inserted into a slot on the brake pad, and multiple limiting rotating pins mounted on the frame, the outer wall of the limiting rotating pins being in contact with the arc-shaped outer wall of the brake pad.

[0009] In one optional embodiment, the second drive assembly includes a second cylinder mounted on the frame, a placement platform mounted on the output end of the second cylinder, a plurality of limiting sleeves mounted on the frame, and a plurality of sliding columns mounted on the placement platform. The sliding columns slide on the placement platform, and the second cylinder is used to drive the placement platform to move closer to or away from the frame in a horizontal direction.

[0010] In one optional embodiment, the drilling assembly includes a second connecting frame mounted on a placement platform, two drilling machines mounted on the second connecting frame, a drill bit mounted on the output end of the drilling machine, and a second synchronous pulley mounted on the input end of the drilling machine.

[0011] In one optional embodiment, the power transmission assembly includes a third servo motor mounted on the frame, a first sprocket mounted on the output end of the third servo motor, a second sprocket mounted on a second synchronous pulley, a chain sleeved on the second sprocket and the first sprocket, and a second transmission belt sleeved on the two second synchronous pulleys.

[0012] In one optional embodiment, the material handling assembly includes a first cylinder mounted on the output end of a lead screw drive, a connecting plate mounted on the output end of the first cylinder, and an electromagnet mounted on the connecting plate.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] 1. The two drilling positions on the drilling assembly are different. On one rotating table, the drilling assembly drills a hole at a fixed position by rotating. During the drilling process, the first drive assembly drives the clamping assembly to rotate the brake pad. In conjunction with the drilling of the hole at a specific position on the drilling assembly, the processing of part of the hole on the brake pad is completed. Then, the brake pad is transferred to the next rotating table by the transmission device for secondary drilling. The two operations can be performed simultaneously. That is, while the first drilling is being performed on one rotating table, the other rotating table can clamp the brake pad or wait for transfer, which greatly increases the number of brake pads processed per unit time and improves the overall processing efficiency.

[0015] 2. In the first drive assembly, the output end of the second servo motor is connected to the first synchronous pulley. When the first synchronous pulley rotates, the first transmission belt fitted on it drives the two rotating disks to rotate synchronously. Through the combination of a second servo motor, the first synchronous pulley, and the first transmission belt, the synchronous drive of the two rotating disks is realized, reducing the number of drive devices. At the same time, the drilling assembly also uses the above method to reduce the number of drive devices.

[0016] 3. After the brake pads are moved to the designated position on the rotating disc, the motor drives the baffle to push the rear end of the brake pads. The baffle pushes the brake pads to the appropriate position according to the preset trajectory and force, ensuring that the position of the brake pads on the rotating disc is accurate.

[0032] This utility model provides an embodiment in which the second drive assembly includes a second cylinder 5 mounted on a frame 1, a placement platform 501 mounted on the output end of the second cylinder 5, a plurality of limiting sleeves 105 mounted on the frame 1, and a plurality of sliding columns 502 mounted on the placement platform 501.

The second sprockets 511 drive the second synchronous pulleys 507 to rotate. The second synchronous pulleys 507 drive another second synchronous pulley 507 to rotate through the second transmission belt 508, thereby causing the drill bits 506 on the four drilling machines 505 to rotate. When the second cylinder 5 is opened, it drives the drilling machine 505 to drill holes in the brake pad 3.

[0033] This utility model provides an embodiment in which a material handling assembly includes a first cylinder 2 mounted on the output end of a lead screw drive 102, a connecting plate 201 mounted on the output end of the first cylinder 2, and an electromagnet 202 mounted on the connecting plate 201. The lead screw drive 102 drives the first cylinder 2 to move horizontally. A set of magnetic attractors on one side of the connecting plate 201 on the first cylinder 2 moves to the brake pad 3 on the conveyor belt. Then, the first cylinder 2 drives the electromagnet 202 to move downward to magnetically attract the brake pad 3. Then, the lead screw drive 102 transports it to the rotating disk 404. The process is repeated. The brake pad 3, which has completed the first hole-opening operation, is transported to the second rotating disk 404 by the electromagnet 202 for the second hole-opening operation. The process is repeated. The material handling assembly transports the brake pad 3 after the two hole-opening operations to the subsequent processing operations.

[0034] Working principle: The lead screw drive component 102 consists of a housing, a lead screw, a threaded sleeve, and a drive motor. The housing is mounted on the first connecting frame 101. The output end of the drive motor is connected to the lead screw. The threaded sleeve is threaded onto the lead screw. The first cylinder 2 is mounted below the threaded sleeve. By turning on the drive motor, the lead screw rotates, causing the threaded sleeve to move. This causes the lead screw drive component 102 to move the first cylinder 2 horizontally. The first cylinder 2 moves the connecting plate 201 and the electromagnet 202 above the brake pad 3 on the conveyor belt. The first cylinder 2 also moves the electromagnet 202 downwards. 02. The brake pads 3 are magnetically attracted, and then the lead screw drive 102 moves the brake pads 3 onto the rotating disk 404. The first servo motor 106 is turned on, driving the straightening plate 107 to rotate and straighten the positions of the two brake pads 3. The second servo motor 401 drives the first synchronous pulley 402 to rotate. The first synchronous pulley 402 drives the two rotating disks 404 to rotate synchronously through the first transmission belt 403. The double-headed cylinder 405 on the rotating disk 404 is turned on, and its output end insert 406 is inserted into the slot 301 on the brake pad 3 to clamp the brake pad 3, while limiting the rotation of the column. The outer wall of 104 fits against the arc-shaped outer wall of the brake pad 3 for positioning. The second cylinder 5 is activated, driving the placement platform 501 to move horizontally closer to the brake pad 3. The third servo motor 503 is activated, and its output end first sprocket 509 drives the two second sprockets 511 to rotate via chain 510. The second sprockets 511 drive the second synchronous pulley 507 to rotate. The second synchronous pulley 507 drives another second synchronous pulley 507 to rotate via the second transmission belt 508, causing the drill bits 506 on the four drilling machines 505 to rotate. As the placement platform 501 moves closer to the brake pad 3, drilling begins. Machine 505 drives drill bit 506 to make a first hole in brake pad 3. After the first hole is made, first cylinder 2 moves brake pad 3 to another rotating disk 404 for a second clamping through lead screw transmission 102. Second servo motor 401 drives brake pad 3 to rotate again. Second cylinder 5 drives placement table 501 to approach brake pad 3 again. Third servo motor 503 drives drill bit 506 to rotate again to make a second hole in brake pad 3. After the two holes are made, first cylinder 2 moves brake pad 3 to the subsequent processing area through lead screw transmission 102.

Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
