Description

Technical Field

[0001] This utility model relates to the field of repair tooling technology, and more specifically, to an electric wheel clamp repair tooling. Background Technology

[0002] As a key braking device, wheel-side brakes are usually installed on the driven wheels of large equipment or vehicles. These driven wheels are part of the running gear. They use the huge force released by the disc spring in the cylinder to force the brake pads to fit tightly against the wheel, so as to achieve a reliable braking effect whether the equipment is in motion or stationary.

[0003] When a brake malfunctions, such as piston wear or ball screw damage, and requires repair or replacement, technicians need to carefully remove the connecting pin on the brake assembly. Once the pin is safely removed, the entire brake assembly can be removed to make room for subsequent repair work. Then, a jack is used to push the ball screw out.

[0004] However, since the fit between the pin and the brake assembly is usually an interference fit, the resistance is relatively large during disassembly. Direct hammering is not only inefficient, but may also cause irreversible damage to the parts. Similarly, the ball screw is also installed with an interference fit, which increases the disassembly burden for the workers. Therefore, it is necessary to improve and optimize it. Summary of the Invention

[0005] In order to overcome the shortcomings of the existing technology, this utility model provides an electric wheel clamp repair tool, which has the advantage of reducing labor burden.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an electric wheel clamp repair fixture, comprising a jack, a push-out fixture, a pull-out fixture, and a connector, wherein a U-shaped fixing frame is fixedly provided on the left side of the push-out fixture, and support feet are fixedly installed at the four corners of the bottom of the push-out fixture, and a jack is placed inside the push-out fixture.

[0007] A hollow jack is placed on the front side of the ejection fixture. A telescopic cylinder is movably installed inside the hollow jack. A connector is threaded onto the left side of the telescopic cylinder. A fixing cylinder is detachably installed on the left side of the connector.

[0008] The pull-out fixture includes a fixed cylinder, a lead screw is rotatably installed inside the fixed cylinder, a gasket is provided between the nut of the lead screw and the outer wall of the fixed cylinder, a limit cylinder is rotatably installed on the outer wall of the lead screw, a pin puller is movably installed inside the limit cylinder, and a threaded hole is opened inside the pin puller, the threaded hole and the lead screw are threadedly connected.

[0009] As a preferred embodiment of this utility model, a connecting groove is provided on the left outer wall of the connector;

[0010] The outer wall of the fixed cylinder is provided with a telescopic groove, and an installation block is movably installed inside the telescopic groove. The installation block and the inner wall of the telescopic groove are elastically connected by a spring, and the top of the installation block extends through the inside of the connecting groove.

[0011] As a preferred technical solution of this utility model, a flange is fixedly provided on the left side of the pin puller, and the flange can be engaged into the pin retaining plate groove.

[0012] As a preferred embodiment of this utility model, a fixed base is fixedly installed on the bottom and right side of the jack. The fixed base and the inner wall of the ejector tool are in contact with each other, which is responsible for stabilizing the jack.

[0013] As a preferred technical solution of this utility model, the brake can be locked and fixed between the inside of the ejection fixture and the jack to ensure that no tilting occurs and that it can withstand the force required for ejection.

[0014] As a preferred embodiment of this utility model, the mounting block is in the shape of a right trapezoid, and the inclined surface of the mounting block is opened to the right.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] 1. This utility model utilizes the operation of a hollow jack to pull the pin shaft puller to the right using a telescopic cylinder, further causing the flange to pull out the pin shaft. The jack and electric wheel clamp are then secured by a push-out fixture. Finally, the jack pushes the ball screw of the electric wheel clamp out from the U-shaped fixed frame by pushing it to the left. Compared to traditional devices, this device uses a hollow jack for power and a pin shaft puller for the pull-out operation, followed by a jacking operation. It is simple and convenient to use, greatly improving maintenance efficiency, reducing labor costs, and enhancing worker safety during maintenance.

[0017] 2. This utility model allows the mounting block to be retracted into the telescopic groove by pressing it down, thus eliminating the need for a fixed connection between the fixing cylinder and the connector. The mounting block then fixes the fixing cylinder and the connector by inserting the fixing cylinder into the connector. Compared to traditional devices, this device allows for easy assembly and disassembly of the fixing cylinder, further enabling the assembly and disassembly of the pull-out tooling. This ensures seamless switching between ejection and pulling operations, reduces workload, improves work efficiency, and enhances maintenance quality. Attached Figure Description

Detailed Implementation

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] like Figures 1 to 6 As shown, this utility model provides a repair fixture for an electric wheel clamp, including a jack 1, a push-out fixture 2, a pull-out fixture 3, and a connector 5. A U-shaped fixing frame 8 is fixedly installed on the left side of the push-out fixture 2, and support legs 7 are fixedly installed at the four corners of the bottom of the push-out fixture 2. The jack 1 is placed inside the push-out fixture 2.

[0027] A hollow jack 20 is placed on the front side of the ejector tool 2. A telescopic cylinder 6 is movably installed inside the hollow jack 20. A connector 5 is threaded on the left side of the telescopic cylinder 6. A fixing cylinder 9 is detachably installed on the left side of the connector 5.

[0028] The pull-out fixture 3 includes a fixed cylinder 9, a lead screw 10 is rotatably mounted inside the fixed cylinder 9, a gasket 11 is provided between the nut of the lead screw 10 and the outer wall of the fixed cylinder 9, a limiting cylinder 12 is rotatably mounted on the outer wall of the lead screw 10, a pin puller 13 is movably mounted inside the limiting cylinder 12, and a threaded hole 15 is opened inside the pin puller 13, which is threadedly connected to the lead screw 10.

[0029] When the electric wheel clamp needs to be disassembled and repaired, the operator first moves the hollow jack 20 to a suitable position, and then engages the flange 14 on the left side of the pin puller 13 with the pin's retaining plate groove. At this time, the operator starts the hollow jack 20, causing the telescopic cylinder 6 inside the hollow jack 20 to move to the right. The telescopic cylinder 6 pulls the fixed cylinder 9 to the right through the connector 5. The fixed cylinder 9 is connected to the pin puller 13 through the screw 10, further causing the pin puller 13 to pull the pin shaft to the right, completing the first step of the disassembly. After the pin shaft is disassembled, the ball screw can be removed. At this time, the operator places the electric wheel clamp inside the ejector fixture 2, ensuring that the electric wheel clamp and the U-shaped fixed frame 8 are engaged. Then, the operator starts the jack 1, causing the output shaft to be ejected to the left, pushing the ball screw of the electric wheel clamp out from the left side of the U-shaped fixed frame 8, completing the disassembly.

[0030] The hollow jack 20 operates to pull the pin puller 13 to the right by the telescopic cylinder 6, which in turn pulls the pin out through the flange 14. The jack 1 and the electric wheel clamp are then secured by the ejector fixture 2. The jack 1 pushes the electric wheel clamp out to the left, causing the ball screw of the electric wheel clamp to be ejected from the U-shaped fixed frame 8. Compared to traditional devices, this device uses the hollow jack 20 for power and the pin puller 13 for the extraction operation, followed by the jack 1 for the ejection operation. It is simple and convenient to use, which can greatly improve maintenance efficiency, reduce labor costs, and improve the safety of workers during maintenance.

[0031] The connector 5 has a connecting groove 16 on its left outer wall;

[0032] The outer wall of the fixed cylinder 9 is provided with a telescopic groove 17, and an installation block 18 is movably installed inside the telescopic groove 17. The installation block 18 and the inner wall of the telescopic groove 17 are elastically connected by a spring 19, and the top of the installation block 18 extends through the inside of the connecting groove 16.

[0033] When the pull-out fixture 3 needs to be disassembled, the operator presses the mounting block 18 downward through the connecting groove 16, so that the mounting block 18 is housed inside the telescopic groove 17. The fixing relationship between the fixing cylinder 9 and the connector 5 is further canceled, so that the fixing cylinder 9 can be removed. If the pull-out fixture 3 needs to be reinstalled, the operator aligns the telescopic groove 17 and the connecting groove 16, and inserts the fixing cylinder 9 into the connector 5. When the fixing cylinder 9 is displaced, the inclined surface of the mounting block 18 will abut against the outer wall of the connector 5, thereby being housed inside the telescopic groove 17. After the fixing cylinder 9 is installed, the mounting block 18 will be reset by the elastic potential energy of the spring 19, thereby fixing the connector 5 and the fixing cylinder 9.

[0034] By pressing the mounting block 18, it is retracted into the telescopic groove 17, thereby eliminating the fixing relationship between the fixing cylinder 9 and the connector 5. The mounting block 18 is then inserted into the connector 5 through the fixing cylinder 9, which fixes the fixing cylinder 9 and the connector 5. Compared with traditional devices, this device can easily disassemble and assemble the fixing cylinder 9, further realizing the disassembly and assembly of the pull-out tool 3, ensuring the switching between ejection and pulling operations, reducing workload, improving work efficiency, and improving maintenance quality.

[0035] The pin puller 13 has a flange 14 fixedly installed on its left side, which can be engaged in the pin retaining plate groove.

[0036] The pin puller 13 can pull the pin shaft to the right through the flange 14, completing the first step of disassembly.

[0037] The jack 1 is fixedly installed with a base 4 at its bottom and right side. The base 4 and the inner wall of the ejector tool 2 are in contact with each other, which is responsible for stabilizing the jack 1.

[0038] The jack 1 is secured and protected by the fixed base 4 to ensure the stable operation of the jacking operation.

[0039] The brake can be locked between the inside of the ejector tool 2 and the jack 1 to ensure that there is no tilting and that it can withstand the force required for ejection.

[0040] The ejector tool 2 and the U-shaped fixing frame 8 ensure the stability of the electric clamp wheel and further ensure the standardization of component assembly and disassembly.

[0041] The mounting block 18 is a right trapezoid, and the inclined surface of the mounting block 18 is opened to the right.

[0042] The inclined surface design of mounting block 18 enables unidirectional fixation of mounting block 18.

[0043] Working principle and usage process of this utility model:

[0044] When the electric wheel clamp needs to be disassembled and repaired, the operator first moves the hollow jack 20 to a suitable position, and then engages the flange 14 on the left side of the pin puller 13 with the pin's retaining plate groove. At this time, the operator starts the hollow jack 20, causing the telescopic cylinder 6 inside the hollow jack 20 to move to the right. The telescopic cylinder 6 pulls the fixed cylinder 9 to the right through the connector 5. The fixed cylinder 9 is connected to the pin puller 13 through the screw 10, further causing the pin puller 13 to pull the pin shaft to the right, completing the first step of the disassembly. After the pin shaft is disassembled, the ball screw can be removed. At this time, the operator places the electric wheel clamp inside the ejector fixture 2, ensuring that the electric wheel clamp and the U-shaped fixed frame 8 are engaged. Then, the operator starts the jack 1, causing the output shaft to be ejected to the left, pushing the ball screw of the electric wheel clamp out from the left side of the U-shaped fixed frame 8, completing the disassembly.

[0045] When the pull-out fixture 3 needs to be disassembled, the operator presses the mounting block 18 downward through the connecting groove 16, so that the mounting block 18 is housed inside the telescopic groove 17. The fixing relationship between the fixing cylinder 9 and the connector 5 is further canceled, so that the fixing cylinder 9 can be removed. If the pull-out fixture 3 needs to be reinstalled, the operator aligns the telescopic groove 17 and the connecting groove 16, and inserts the fixing cylinder 9 into the connector 5. When the fixing cylinder 9 is displaced, the inclined surface of the mounting block 18 will abut against the outer wall of the connector 5, thereby being housed inside the telescopic groove 17. After the fixing cylinder 9 is installed, the mounting block 18 will be reset by the elastic potential energy of the spring 19, thereby fixing the connector 5 and the fixing cylinder 9.
