Description

Technical Field

[0001] This utility model relates to the field of spring brake chamber technology, specifically to an auxiliary device for disassembling and assembling a spring brake chamber. Background Technology

[0002] The spring brake chamber is an important component of the automotive braking system. It is divided into two types: double diaphragm spring brake chamber and combined spring brake chamber. It is mainly used to eliminate vibration and change the transmission characteristics to achieve a comfortable driving state. The spring brake chamber can perform mechanical movement in a gas-liquid two-phase mixture state. It is widely used in the transmission systems of mechanical equipment, steam turbines and other applications. During use, the diaphragm, spring, seals and other components in the spring brake chamber may be damaged due to wear, aging or failure. In order to ensure the normal operation of the braking system and driving safety, it is necessary to repair or replace these damaged components.

[0003] However, existing spring brake chamber disassembly and assembly devices lack auxiliary disassembly and assembly structures and cannot drive the spring brake chamber disassembly and assembly devices to move, resulting in low disassembly and assembly efficiency. Therefore, we propose a spring brake chamber disassembly and assembly auxiliary device. Utility Model Content

[0004] To address the problems in the existing technology, this utility model provides an auxiliary device for disassembling and assembling a spring brake chamber. This new spring brake chamber disassembly and assembly device has an auxiliary disassembly and assembly structure and can drive the spring brake chamber disassembly and assembly device to move, thereby effectively improving the efficiency of disassembly and assembly.

[0005] The technical solution adopted by this utility model to solve its technical problem is a spring brake chamber disassembly and assembly auxiliary device, including a base plate, a spring brake chamber, a drive assembly and an electric screwdriver. A mounting base is provided at one end of the top of the base plate, and the spring brake chamber is installed at the upper end of the mounting base. A drive assembly is provided at the other end of the top of the base plate. The drive assembly includes a stepper motor, a lead block and a lead screw. A lead block is provided on one side of the stepper motor, and the output end of the stepper motor is connected to the lead screw, which passes through the lead block.

[0006] A mounting shell is provided on one side of the spring brake chamber. Electric screwdrivers are evenly installed around the periphery of the mounting shell. The output end of the electric screwdriver is connected to an internal hex screwdriver bit. A first connecting plate is installed on one side of the spring brake chamber through a hex head bolt. The internal hex screwdriver bit is sleeved around the hex head bolt. A second connecting plate is installed on the top of the screw block. One side of the mounting shell is connected to the second connecting plate through a connecting rod.

[0007] By adopting the above technical solution, the new spring brake chamber disassembly and assembly device has an auxiliary disassembly and assembly structure and can drive the spring brake chamber disassembly and assembly device to move, thereby effectively improving the efficiency of disassembly and assembly.

[0008] Specifically, the drive assembly also includes guide rods and limiting blocks. Guide rods are provided on both sides of the lead screw. The limiting block is fixedly installed at one end of the top of the base plate. One end of the guide rod is connected to the mounting base, and the other end of the guide rod passes through the lead screw and is connected to the limiting block.

[0009] By adopting the above technical solution, the limiting block can support the guide rod, and the guide rod can guide the movement of the lead screw.

[0010] Specifically, a slide rail is provided on one side of the top of the base plate, and the bottom of the wire block is located inside the slide rail.

[0011] Specifically, the other end of the lead screw is connected to the limiting block via a bearing.

[0012] Specifically, a flexible pad is provided on the inner side of the top of the mounting base.

[0013] By adopting the above technical solution, the flexible pad is made of silicone material, which plays a role in anti-slip and enhances the stability of the spring brake chamber.

[0014] The beneficial effects of this utility model are as follows: The spring brake chamber disassembly and assembly auxiliary device of this utility model, through the cooperation of a stepper motor, a lead screw, and a lead block, drives the mounting housing and an electric screwdriver to move via lead screw transmission. The operator places the hexagonal screwdriver bit at the end of the electric screwdriver around the hexagonal head bolt and turns on the electric screwdriver to remove the hexagonal head bolt, thus completing the disassembly of the spring brake chamber. Furthermore, the stepper motor, lead block, and lead screw, through lead screw transmission, drive the second connecting plate, connecting rod, mounting housing, and electric screwdriver away from the spring brake chamber, thereby disengaging the mounting housing and electric screwdriver from the spring brake chamber.

[0021] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0022] To improve the efficiency of disassembly and assembly, such as Figure 1-4 As shown, the spring brake chamber disassembly and assembly auxiliary device of this utility model includes a base plate 1, a spring brake chamber 3, a drive assembly 4, and an electric screwdriver 7. A mounting base 2 is provided at one end of the top of the base plate 1, and the spring brake chamber 3 is installed at the upper end of the mounting base 2. The drive assembly 4 is provided at the other end of the top of the base plate 1. The drive assembly 4 includes a stepper motor 401, a lead block 402, and a lead screw 403. The lead block 402 is provided on one side of the stepper motor 401, and the output end of the stepper motor 401 is connected to the lead screw 403. The lead screw 403 passes through the lead block 402.

[0023] A mounting shell 5 is provided on one side of the spring brake air chamber 3. Electric screwdrivers 7 are evenly installed around the periphery of the mounting shell 5. The output end of the electric screwdrivers 7 is connected to an internal hex screwdriver bit 12. A first connecting plate 6 is installed on one side of the spring brake air chamber 3 through a hex head bolt 10. The internal hex screwdriver bit 12 is sleeved around the hex head bolt 10. A second connecting plate 8 is installed on the top of the screw block 402. One side of the mounting shell 5 is connected to the second connecting plate 8 through a connecting rod 9.

[0024] In use, the stepper motor 401, lead screw 403 and lead block 402 work together to drive the mounting shell 5 and electric screwdriver 7 to move through lead screw transmission. The operator puts the internal hex screwdriver bit 12 at the end of the electric screwdriver 7 around the hex head bolt 10, turns on the electric screwdriver 7, and removes the hex head bolt 10, thereby completing the disassembly of the spring brake air chamber 3.

[0025] Stepper motor 401, lead block 402 and lead screw 403 drive the second connecting plate 8, connecting rod 9, mounting shell 5 and electric screwdriver 7 to move away from spring brake chamber 3 through lead screw transmission, thereby driving mounting shell 5 and electric screwdriver 7 to disengage from spring brake chamber 3.

[0026] For example, such as Figure 2 As shown, the drive assembly 4 also includes a guide rod 404 and a limiting block 405. Guide rods 404 are provided on both sides of the lead screw 403. The limiting block 405 is fixedly installed on one end of the top of the base plate 1. One end of the guide rod 404 is connected to the mounting base 2. The other end of the guide rod 404 passes through the lead screw block 402 and is connected to the limiting block 405.

[0027] In use, the limiting block 405 can support the guide rod 404, and the guide rod 404 can guide the movement of the lead screw 403.

[0028] For example, such as Figure 1 , Figure 2 As shown, a slide rail 11 is provided on one side of the top of the base plate 1, and the bottom of the wire block 402 is located inside the slide rail 11.

[0029] When in use, the slide rail 11 can enhance the smoothness of the movement of the wire block 402.

[0030] For example, such as Figure 4 As shown, the other end of the lead screw 403 is connected to the limiting block 405 via the bearing 14.

[0031] In use, this method allows the lead screw 403 to rotate smoothly.

[0032] For example, such as Figure 2 As shown, a flexible pad 13 is provided on the inner side of the top of the mounting base 2.

[0033] When in use, the flexible pad 13 is made of silicone material to prevent slipping and enhance the stability of the spring brake chamber 3.

[0034] When using this utility model, the personnel place the spring brake air chamber 3 to be disassembled on the top of the mounting base 2. The flexible pad 13 can play an anti-slip role and prevent the spring brake air chamber 3 from sliding.

[0035] Furthermore, the stepper motor 401 in the drive assembly 4 can drive the lead screw 403 to rotate, and the lead screw 403 can drive the lead block 402 to move linearly. The lead block 402 can then drive the mounting housing 5 and the electric screwdriver 7 to move through the lead screw transmission. The operator puts the hexagonal screwdriver bit 12 at the end of the electric screwdriver 7 around the hexagonal head bolt 10, turns on the electric screwdriver 7, and can remove the hexagonal head bolt 10, thereby completing the disassembly of the spring brake chamber 3.

[0036] Furthermore, the stepper motor 401, lead block 402 and lead screw 403 drive the second connecting plate 8, connecting rod 9, mounting shell 5 and electric screwdriver 7 to move away from the spring brake chamber 3 through the lead screw transmission, thereby driving the mounting shell 5 and electric screwdriver 7 to disengage from the spring brake chamber 3.

[0037] Furthermore, during the movement of the wire block 402, the slide rail 11 can limit the movement of the wire block 402 at the bottom of the wire block 402, and the guide rods 404 on both sides of the lead screw 403 can also limit the movement of the wire block 402, thereby enhancing the stability of the wire block 402 during movement.
