Description

Technical Field

[0001] This utility model relates to the field of brake assembly, and more particularly to a caliper pin press-fitting device. Background Technology

[0002] Brake calipers generally consist of a caliper body and a return spring. The return spring is positioned and fixed using a pin, and in current technology, the pin is typically installed manually. Due to the large size of the caliper body, the significant pre-set elastic force of the spring, and the small size of the pin hole, manual installation is labor-intensive, difficult to align, and inefficient. Utility Model Content

[0003] This utility model addresses the shortcomings of existing technologies by providing a caliper pin press-fitting device.

[0004] To solve the above-mentioned technical problems, the present invention provides a solution through the following technical method: Caliper pin press-fitting equipment, including base, positioning fixture, and press-fitting unit; The base has an installation platform, and the positioning fixtures and pressing units are installed on the installation platform. The positioning fixture is fixedly installed on the installation platform and is used to position and install the caliper equipment. After placement, the caliper pin axis is parallel to the movement direction of the pressing unit. The pressing unit is fixedly installed on the mounting platform. It has a first horizontal pushing mechanism. The front end of the first horizontal pushing mechanism is connected to an assembly part with an assembly pin. The front end of the assembly part has a detachable pressing head. It also includes a longitudinal push unit, and the first transverse push mechanism is installed on the longitudinal push unit and can be driven by the longitudinal push unit to move longitudinally.

[0005] Preferably, the first lateral push unit includes a lateral push electric cylinder and a slide rail, with the assembly installed at the front end of the lateral push electric cylinder and slidingly engaging with the slide rail.

[0006] Preferably, the system also includes a second horizontal pushing mechanism, which includes a column fixedly supported on the mounting platform. The column is located on the left and right sides of the first horizontal pushing unit, and the second horizontal pushing mechanism is located directly above the first horizontal pushing mechanism. The second horizontal pushing mechanism includes a second guide rail, on which a support plate is slidably mounted, and a second horizontal pushing cylinder, which is connected to the support plate and drives the support plate to slide along the second guide rail.

[0007] Preferably, it also includes a vertical pressing cylinder, the piston rod end of which is connected to a pressure rod, a pressure plate is connected to the pressure rod, and a support guide rod is fixedly installed on the pressure plate. The support guide rod and the pressure rod are both vertically arranged parallel to each other. The guide rod passes through the support plate and extends above it and slides with the support plate.

[0008] Preferably, a second guide rod is fixedly installed on the lower side of the top plate, and a first elastic support is provided on the support plate below the second guide rod. Under the drive of the vertical cylinder, the second guide rod presses on the first elastic support to accumulate elastic potential energy.

[0009] Preferably, a second elastic support for clamping is fixedly installed below the pressure plate.

[0010] Compared with existing technologies, this solution has the following advantages: This solution positions and fixes the caliper by positioning, and then elastically presses the caliper from above to prevent it from shaking and ensure that the caliper surface is not damaged.

Detailed Implementation

[0015] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments.

[0016] Example 1 The caliper 90 pin pressing equipment includes a base 1, a positioning fixture 2, and a pressing unit 3; The base 1 has an installation platform 4, and the positioning fixture 2 and the pressing unit 3 are installed on the installation platform 4. Positioning fixture 2 is fixedly installed on the installation platform 4 and is used to position and install caliper 90 equipment. After placement, the axial direction of the pin of caliper 90 is parallel to the movement direction of pressing unit 3. The pressing unit 3 is fixedly mounted on the mounting platform 4. It has a first horizontal pushing mechanism 5, and the front end of the first horizontal pushing mechanism 5 is connected to an assembly part 6 for mounting pins. The front end of the assembly part 6 has a detachable pressing head 7. The first horizontal pushing mechanism 5 is driven by an electric cylinder 9, or alternatively, by a motor driving a ball screw structure. Electric control offers higher precision than pneumatic control and is easier to program.

[0017] Since two pins are being pressed in, a longitudinal push unit 8 is also included. A first transverse push mechanism 5 is mounted on the longitudinal push unit 8 and can be driven by the longitudinal push unit 8 to move longitudinally, thus allowing the installation of the second pin after the first pin is installed. This achieves fully automated installation. The longitudinal push unit 8 includes a longitudinal push cylinder 81, a longitudinal push slide rail 82, and a longitudinal push platform 83. The first transverse push mechanism 5 is mounted on the longitudinal push platform 83, which can move along the longitudinal push slide rail 82 under the drive of the longitudinal push cylinder 81.

[0018] Specifically, the first lateral push unit includes a lateral push electric cylinder 9 and a slide rail 10. The assembly 6 is installed at the front end of the lateral push electric cylinder 9 and slides in cooperation with the slide rail 10. Specifically, the front end of the electric cylinder 9 is provided with a piston rod, which is installed on the slide rail 10. The assembly 6 is fixedly installed at the front end of the piston rod and has a hole for a positioning pin. During operation, the assembly 6 pushes the pin to move laterally, causing the pin to be pushed into the corresponding mounting hole of the brake.

[0019] Specifically, it also includes a second horizontal push mechanism 11, which is used to position the upper end of the caliper 90 so that the caliper 90 will not shake or jump during the installation of the pin.

[0020] The specific second horizontal pushing mechanism 11 includes columns 12 fixedly supported on the mounting platform 4. The columns 12 are located on the left and right sides of the first horizontal pushing unit, and the first horizontal pushing unit is supported on the upper end of the columns 12. There are four columns 12, two on the left and two on the right.

[0021] The second horizontal push mechanism 11 is located directly above the first horizontal push mechanism 5. The second horizontal push mechanism 11 includes a second guide rail 13, on which a support plate 14 is slidably mounted, and also includes a second horizontal push cylinder, which is connected to the support plate 14 and drives the support plate 14 to slide along the second guide rail 13.

[0022] Preferably, the system also includes a vertical pressing cylinder 15, with a pressure rod 16 connected to the piston rod end of the vertical pressing cylinder 15. A pressure plate 17 is connected to the pressure rod 16, and a support guide rod 18 is fixedly installed on the pressure plate 17. The support guide rod 18 and the pressure rod 16 are both arranged vertically and parallel to each other. The guide rod passes through the support plate 14 and extends above it, and slides with the support plate 14. The system also includes a top plate, which is fixed to the upper end of the support guide rod 18.

[0023] Specifically, in this embodiment, a second guide rod 19 is fixedly installed on the lower side of the top plate, and a first elastic support member 20 is provided below the second guide rod 19 on the support plate 14. Under the drive of the vertical cylinder, the second guide rod 19 presses against the first elastic support member 20 to accumulate elastic potential energy. The first support member includes a support rod and a spring disposed within the support rod, belonging to a spring rod structure. The first elastic support member 20 can assist the piston of the vertical cylinder in returning to its original position during retraction.

[0024] A second elastic support 21 for clamping is fixedly installed below the pressure plate 17. The second elastic support 21 is used to abut against the upper end of the caliper 90 to ensure the reliability of the caliper 90. The structure of the second elastic support 21 is the same as that of the first elastic support 20.

[0025] During operation, the pin is inserted into the assembly channel on the table (not shown in the diagram); specifically, it is a long cylindrical structure with an internal channel. The caliper 90 is then placed in the positioning fixture 2. The second horizontal push mechanism 11 is activated, causing the pressure plate 17 to move directly above the caliper 90. Then, a vertical cylinder moves the pressure plate 17 downwards, and the second elastic support 21 elastically presses against the back of the caliper 90. The first horizontal push mechanism 5 is activated, and its electric cylinder 9 moves the assembly part 6 into the assembly channel, pushing the pin into the corresponding hole in the caliper 90. Clearly, this hole is coaxial with the channel. After the pin is pushed into place, the second pin is assembled. The vertical push cylinder is activated, pushing the axis of the second horizontal push mechanism 11 so that it is collinear with the axis of the second pin hole.

[0026] This solution positions and fixes the caliper 90 using a positioning method, and then elastically presses the caliper 90 from above to prevent it from shaking and to ensure that the surface of the caliper 90 is not damaged. Then, a horizontal push mechanism is used to feed the pin. The design of the double horizontal push mechanism can ensure the horizontal push speed at the front end and the horizontal push accuracy at the rear end, thus ensuring the reliability and accuracy of the assembly.
