Description

Technical Field

[0001] This utility model relates to the field of brake processing technology, and in particular to a fixing structure for processing brake housing. Background Technology

[0002] In the brake manufacturing process, the machining accuracy of the brake housing directly affects the overall performance and safety stability of the brake. The fixing effect of the brake housing during machining is one of the core factors that determine the machining accuracy.

[0003] Existing manual bolt clamping structures rely on manually tightening multiple bolts to secure the brake housing to the clamping plates. However, due to subjective differences in manual force and varying force transmission efficiency at different bolt locations, inconsistent clamping force between different clamping plates is prone to occur. Over-clamping in some areas can lead to irreversible plastic deformation of the brake housing, while under-clamping in others can cause workpiece displacement during milling, drilling, and other machining processes, ultimately resulting in dimensional deviations. Furthermore, to meet assembly and functional requirements, the brake housing typically features irregular structures such as raised reinforcing ribs and recessed mounting grooves on its outer surface. Traditional clamping structures often use fixed flat clamping plates that can only contact smooth surfaces. When facing uneven surfaces, the flat clamping plates only contact some raised areas, leaving recessed areas suspended, leading to scattered and unstable clamping points. To overcome these disadvantages, this invention provides a fixing structure for brake housing machining. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a fixed structure for processing brake housings.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a fixed structure for machining a brake housing, comprising a machining table, a first slot on one side of the machining table, a first slider slidably connected to the first slot, a second slot on one side of the machining table, a second slider slidably connected to the second slot, an air chamber fixedly connected to one side of the second slider, an air inflation component on one side of the first slider, a clamping component on one side of the air chamber, and a power component on one side of the machining table and located on both sides of the second slot.

[0006] Furthermore, a second limiting rod is fixedly connected to the second slot, and the second limiting rod and the second slider are slidably connected. A first limiting rod is fixedly connected to the first slot, and the first limiting rod and the first slider are slidably connected.

[0007] Furthermore, the inflation assembly includes an air pump fixedly connected to one side of the first slider, a connecting rod fixedly connected to one side of the air pump, one end of the connecting rod fixedly connected to one side of the inflation chamber, a metal air pipe fixedly connected to the air pump output port, one end of the metal air pipe fixedly connected to the air inlet of the inflation chamber, a solenoid valve fixedly connected to the metal air pipe, and a pressure sensor fixedly connected to one side of the inflation chamber, the detection end of the pressure sensor penetrating through the inflation chamber and located inside the inflation chamber.

[0008] Furthermore, the clamping assembly includes several sliding holes formed on one side of the inflation chamber, a sliding rod slidably connected to the sliding holes, a sealing plate fixedly connected to one end of the sliding rod inside the inflation chamber, a sealing strip fixedly connected to one side of the sealing plate, a spring fixedly connected to one side of the inflation chamber and around the sliding holes, a rotating seat fixedly connected to one end of the sliding rod, a rotating block rotatably connected to the rotating seat, a clamping plate fixedly connected to one side of the rotating block, and one end of the spring fixedly connected to one side of the rotating seat.

[0009] Furthermore, the power assembly includes an electric hydraulic cylinder fixedly connected to one side of the processing table and to both sides of the second slot, a limit plate fixedly connected to one side of the processing table and to both sides of the second slot, and the output end of the electric hydraulic cylinder fixedly connected to one side of the air chamber through the limit plate.

[0010] Furthermore, a control board is fixedly connected to one side of the processing table, a driver is fixedly connected to one side of the control board, a PLC controller is fixedly connected to one side of the control board and located on the side of the driver, a control panel is fixedly connected to one side of the PLC controller, the control panel and the PLC controller are electrically connected, and the PLC controller and the driver are electrically connected.

[0011] The beneficial effects of this utility model are:

[0012] In use, this invention achieves uniform control of clamping force through an inflation assembly. During processing, an air pump inflates the inflation chamber, creating uniform pressure. This pressure acts synchronously on multiple sealing plates, pushing them to move the sliding rods within the sliding holes. Ultimately, the clamping plates at the ends of each sliding rod move synchronously towards the brake housing and apply clamping force. Because the pressure inside the inflation chamber is uniform and the structures of each sealing plate and sliding rod are identical, it ensures that each clamping plate exerts the same clamping force on the brake housing. This effectively avoids the problem of excessive or insufficient local force caused by structural errors in traditional mechanical clamping, preventing deformation or displacement of the brake housing during processing due to uneven force. Furthermore, the rotating connection structure between the rotating block and the rotating seat in the clamping assembly allows the clamping plates to adaptively adjust their angle according to the surface shape of the brake housing, improving adaptability to brake housings of different specifications and surface conditions. It also enhances clamping stability and avoids processing wobbling caused by loose contact between the clamping plates and the housing surface. Attached Figure Description

A connecting rod 14 is fixedly connected to one side of the air pump 9. One end of the connecting rod 14 is fixedly connected to one side of the inflation chamber 13. A metal air pipe 15 is fixedly connected to the output port of the air pump 9. One end of the metal air pipe 15 is fixedly connected to the air inlet of the inflation chamber 13. A solenoid valve 16 is fixedly connected to the metal air pipe 15. A pressure sensor 17 is fixedly connected to one side of the inflation chamber 13. The detection end of the pressure sensor 17 penetrates through the inflation chamber 13 and is located inside the inflation chamber 13, and is used to inflate the inflation chamber 13.

[0023] like Figure 1-3 As shown, the clamping assembly includes several sliding holes 18 on one side of the inflation chamber 13. A sliding rod 19 is slidably connected to the sliding hole 18. A sealing plate 23 is fixedly connected to one end of the sliding rod 19 inside the inflation chamber 13. A sealing strip 24 is fixedly connected to one side of the sealing plate 23. A spring 20 is fixedly connected to one side of the inflation chamber 13 and around the sliding hole 18. A rotating seat 21 is fixedly connected to one end of the sliding rod 19. A rotating block 25 is rotatably connected to the rotating seat 21. A clamping plate 22 is fixedly connected to one side of the rotating block 25. One end of the spring 20 is fixedly connected to one side of the rotating seat 21 for clamping the brake housing.

[0024] like Figure 1-3 As shown, the power assembly includes an electric hydraulic cylinder 26 fixedly connected to one side of the processing table 1 and both sides of the second slot 10. A limit plate 27 is fixedly connected to one side of the processing table 1 and both sides of the second slot 10. The output end of the electric hydraulic cylinder 26 passes through the limit plate 27 and is fixedly connected to one side of the inflation chamber 13, and is used to drive the inflation chamber 13 to move towards the brake housing.

[0025] like Figure 1-3 As shown, a control board 2 is fixedly connected to one side of the processing table 1, a driver 3 is fixedly connected to one side of the control board 2, a PLC controller 4 is fixedly connected to one side of the control board 2 and the driver 3, a control panel 5 is fixedly connected to one side of the PLC controller 4, the control panel 5 and the PLC controller 4 are electrically connected, and the PLC controller 4 and the driver 3 are electrically connected, which is used to control the equipment on the device.

[0026] Working principle: First, check whether the whole device is intact. The operator operates the control panel 5 to control the equipment on the device through the PLC controller 4, and uses the driver 3 to make the electric hydraulic cylinder 26 on the processing table 1 move synchronously.

[0027] In use, the brake housing to be processed is first placed on the processing table 1. The electric hydraulic cylinders 26 located on both sides of the second slot 10 are started. The output end of the electric hydraulic cylinder 26 pushes the air chamber 13 to move. At this time, the second slider 11, which is fixedly connected to the air chamber 13, slides along the second limit rod 12 in the second slot 10. At the same time, the air chamber 13 drives the air pump 9 to move synchronously through the connecting rod 14. The first slider 7 on one side of the air pump 9 slides along the first limit rod 8 in the first slot 6, so that the clamping mechanism moves smoothly towards the brake housing until the clamping plate 22 is close to the surface of the housing. Then, the air pump 9 of model GV-0.25 / 8 is started, and the solenoid valve 16 on the metal air pipe 15 is opened. The gas generated by the air pump 9 is injected into the air chamber 13 through the metal air pipe 15. As the gas in the air chamber 13 increases, a uniform pressure is formed inside. This pressure acts on the multiple sealing plates 23 in the air chamber 13, pushing the sealing plates 23 to move. The slide bar 19 slides outward along the slide hole 18, and the rotating seat 21 at the end of the slide bar 19 moves accordingly, so that the clamping plate 22 on the rotating block 25 applies clamping force to the brake housing synchronously. During this process, the pressure sensor 17 of model ifmPQ3050 on one side of the air chamber 13 detects the internal pressure in real time. When the pressure reaches the target value set by the control panel 5, the pressure sensor 17 sends a signal to the PLC controller 4. The PLC controller 4 controls the air pump 9 to stop working and closes the solenoid valve 16. At this time, due to the uniform pressure in the air chamber 13, the clamping force of each clamping plate 22 on the brake housing is completely consistent, avoiding uneven local force. During the contact process between the clamping plate 22 and the brake housing, the surface of the brake housing has unevenness. The clamping plate 22 will be subjected to the reaction force of the housing surface at the moment of contact, which drives the rotating block 25 to rotate flexibly around the rotating seat 21 until the surface of the clamping plate 22 is completely in contact with the uneven contour of the housing.
