Description

Technical Field

[0001] This utility model relates to the field of automotive brake disc technology, specifically to an automotive brake disc surface heat treatment device. Background Technology

[0002] As a key component of the automotive braking system, the performance of the brake disc directly affects vehicle safety. During braking, the brake disc must withstand enormous friction and high temperatures, thus requiring excellent wear resistance, thermal fatigue resistance, and sufficient strength. Heat treatment is an important process for improving the performance of brake disc materials. Proper heat treatment can adjust the internal structure of the brake disc, increasing its hardness, wear resistance, and thermal fatigue resistance, thereby extending its service life and ensuring vehicle braking safety.

[0003] Existing heat treatment devices for automotive brake discs often fail to ensure uniform heating across all parts of the disc during the heating process. Some devices use a fixed heating method, where the brake disc does not rotate during heating. This results in areas near the heat source becoming excessively hot, while areas farther from the heat source remain cooler, creating a significant temperature gradient. This uneven temperature distribution leads to microstructural differences in the brake disc after heat treatment, causing uneven hardness, deformation, and other problems, severely impacting the quality and performance of the brake disc. Utility Model Content

[0004] The purpose of this invention is to provide a heat treatment device for the surface of automotive brake discs to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a heat treatment device for the surface of an automotive brake disc, comprising a worktable, a rotating clamping mechanism provided on the top left side of the worktable, and a heating mechanism provided on the top right side of the worktable; The rotating clamping mechanism includes fixed columns, which are symmetrically fixedly connected to the top left side of the worktable. Fixed seats are fixedly connected to the top of the four fixed columns, and servo motors are fixedly connected to the bottom of the fixed seats. A turntable is fixedly connected to the output end of the servo motor, and a housing is fixedly connected to the top of the turntable. A bidirectional lead screw is rotatably connected to the back of the inner wall of the housing, and a crank is fixedly connected to the front end of the bidirectional lead screw. Limiting rods are symmetrically fixedly connected to the front and rear sides of the inner wall of the housing. Moving plates are symmetrically threaded onto the surface of the bidirectional lead screw. Moving frames are symmetrically fixedly connected to one side of each of the two moving plates, and clamping blocks are fixedly connected to the other ends of the two sets of moving frames. A placement plate is fixedly connected to the top of the housing.

[0006] Preferably, the front of the housing has a hole that matches the bidirectional lead screw, and the surface of the bidirectional lead screw passes through and is rotatably connected to the hole.

[0007] Preferably, one side of each of the two movable plates has a hole that matches the limiting rod, and the two movable plates are slidably connected to the surface of the limiting rod through the hole. The limiting rod limits the two movable plates, so that the two movable plates move towards each other as the bidirectional lead screw rotates.

[0008] Preferably, the top of the box has a groove, and the surface of the movable frame extends through and slides back and forth within the groove.

[0009] Preferably, the heating mechanism includes an L-shaped base, which is fixedly connected to the top right side of the workbench. A hydraulic cylinder is fixedly connected to the top right side of the L-shaped base, and a connecting plate is fixedly connected to the output end of the hydraulic cylinder. A connecting rod is fixedly connected to the left side of the connecting plate near the top, and a heating block is fixedly connected to the other end of the connecting rod. A support plate is fixedly connected to the bottom left side of the L-shaped base, and a power supply body is fixedly connected to the bottom right side of the L-shaped base.

[0010] Preferably, the top of the L-shaped base has a groove near the left side that matches the connecting plate, and the surface of the connecting plate is slidably connected to the groove from side to side. The power supply body is connected to the heating block via a power cord.

[0011] Preferably, the support plate has a hole on its left side near the top that matches the connecting rod, and the connecting rod passes through the surface of the hole and slides left and right in the hole. The support plate supports the connecting rod, allowing the connecting rod to move stably left and right.

[0012] Compared with the prior art, the present invention provides a heat treatment device for the surface of automotive brake discs, which has the following beneficial effects: This automotive brake disc surface heat treatment device features a rotating clamping mechanism with a stable foundation built by fixed columns and seats. A servo motor drives a turntable to rotate the housing, enabling the brake disc placed on the mounting plate to rotate precisely and stably. This design ensures uniform heating of all parts of the brake disc during heat treatment, effectively avoiding quality defects caused by uneven local heating and improving the overall performance of the brake disc after heat treatment. The combination of a two-way lead screw and a crank handle allows the operator to easily rotate the two-way lead screw by manually cranking the handle, which in turn drives two moving plates to move towards each other under the limiting action of the limit rod. This adjustment method is flexible and convenient, quickly adapting to the clamping needs of brake discs of different sizes, greatly improving the versatility and practicality of the device. At the same time, the combination of the moving frame and the clamping block ensures effective clamping of the brake disc, preventing displacement during rotation and ensuring the smooth progress of the heat treatment process.

[0013] The automotive brake disc surface heat treatment device uses a hydraulic cylinder to drive the connecting plate, which in turn moves the connecting rod and the heating block left and right. This design allows the heating block to quickly and accurately approach or move away from the brake disc, achieving precise control of the heating process. When heating is required, the heating block can quickly reach the designated position for heating, and after heating is completed, it can be moved away in time to avoid overheating the brake disc, thus improving the accuracy and efficiency of heat treatment.

[0018] This utility model provides the following technical solution: Example 1: Please refer to Figure 1-4 This utility model provides a technical solution: a heat treatment device for the surface of an automobile brake disc, including a workbench 1, a rotating clamping mechanism 2 arranged on the top left side of the workbench 1, and a heating mechanism 3 arranged on the top right side of the workbench 1. The rotary clamping mechanism 2 includes fixed columns 21, which are symmetrically fixed to the top left side of the workbench 1. Fixed seats 22 are fixedly connected to the top of the four fixed columns 21. Servo motors 23 are fixedly connected to the bottom of the fixed seats 22. Turntables 24 are fixedly connected to the output end of the servo motors 23. A housing 25 is fixedly connected to the top of the turntables 24. A bidirectional lead screw 26 is rotatably connected to the back of the inner wall of the housing 25. A crank handle 27 is fixedly connected to the front end of the bidirectional lead screw 26. Limiting rods 28 are symmetrically fixed to the front and rear sides of the inner wall of the housing 25. Moving plates 29 are symmetrically threaded to the surface of the bidirectional lead screw 26. Moving frames 211 are symmetrically fixed to one side of the two moving plates 29. Clamping blocks 212 are fixedly connected to the other end of the two sets of moving frames 211. A placement plate 213 is fixedly connected to the top of the housing 25.

[0019] The front of the housing 25 has a hole that matches the bidirectional lead screw 26, and the surface of the bidirectional lead screw 26 passes through and is rotatably connected to the hole.

[0020] Two movable plates 29 have holes on one side that match the limiting rod 28, and the two movable plates 29 are slidably connected to the surface of the limiting rod 28 through the holes. The limiting rod 28 limits the two movable plates 29, so that the two movable plates 29 move towards each other as the bidirectional lead screw 26 rotates.

[0021] The top of the housing 25 has a slot, and the surface of the movable frame 211 is penetrated and slidably connected to the slot.

[0022] Example 2: Please refer to Figure 5-6 Furthermore, based on Example 1, heating mechanism 3 is obtained.

[0023] The heating mechanism 3 includes an L-shaped base 31, which is fixedly connected to the top right side of the workbench 1. A hydraulic cylinder 32 is fixedly connected to the top right side of the L-shaped base 31. A connecting plate 33 is fixedly connected to the output end of the hydraulic cylinder 32. A connecting rod 34 is fixedly connected to the left side of the connecting plate 33 near the top. A heating block 35 is fixedly connected to the other end of the connecting rod 34. A support plate 36 is fixedly connected to the bottom left side of the L-shaped base 31. A power supply body 37 is fixedly connected to the bottom right side of the L-shaped base 31.

[0024] The top of L-shaped base 31 is provided with a groove near the left side that matches the connecting plate 33. The surface of the connecting plate 33 is penetrated and slidably connected to the groove. The power supply body 37 is connected to the heating block 35 through a power cord.

[0025] The support plate 36 has a hole on its left side near the top that matches the connecting rod 34. The connecting rod 34 passes through the surface of the hole and slides left and right. The support plate 36 supports the connecting rod 34, allowing the connecting rod 34 to move left and right stably.

[0026] In actual operation, when this device is in use, four fixed columns 21 are symmetrically fixed to the top left side of the workbench 1, and their top ends are all fixedly connected to the fixed base 22, providing a stable support foundation for the entire rotating clamping mechanism 2. The servo motor 23 installed at the bottom of the fixed base 22 serves as the power source. When the servo motor 23 starts, its output end drives the turntable 24 to rotate. Since the top of the turntable 24 is fixedly connected to the housing 25, the rotation of the turntable 24 will synchronously drive the housing 25 to rotate. A bidirectional lead screw 26 is rotatably connected to the back of the inner wall of the housing 25, and a crank handle 27 is fixedly connected to the front end of the bidirectional lead screw 26. The operator can rotate the bidirectional lead screw 26 by cranking the crank handle 27. Limit rods 28 are symmetrically fixedly connected to the front and rear sides of the inner wall of the housing 25. Holes matching the limit rods 28 are opened on one side of the two moving plates 29, so that the moving plates 29 can slide back and forth on the surface of the limit rods 28 through the holes. The function of the limit rods 28 is to limit the moving plates 29. To prevent the moving plate 29 from rotating along with the double-acting screw 26, the moving plate 29 is ensured to move only in a straight line along the limit rod 28. The double-acting screw 26 is symmetrically threaded with moving plates 29. When the double-acting screw 26 rotates, according to the principle of thread transmission, the two moving plates 29 will move towards each other as the double-acting screw 26 rotates. Each moving plate 29 is symmetrically fixedly connected to a moving frame 211 on one side. The other end of the two sets of moving frames 211 is fixedly connected to a clamping block 212. The top of the housing 25 is fixedly connected to a placement plate 213. When placing the brake disc, it is placed on the placement plate 213. Then, the crank handle 27 is turned to rotate the double-acting screw 26, which drives the two moving plates 29 to move towards each other. Then, the moving frame 211 moves the clamping block 212 closer to the brake disc, and finally the brake disc is clamped and fixed. At this time, the servo motor 23 is started, and the turntable 24 drives the housing 25 to rotate, which in turn makes the clamped brake disc rotate together, preparing for subsequent uniform heating. L-shaped base 31 is fixedly connected to the top right side of the workbench 1. A hydraulic cylinder 32 is fixedly connected to the top right side of the base. The output end of the hydraulic cylinder 32 is fixedly connected to a connecting plate 33. A groove matching the connecting plate 33 is opened near the left side of the top of the L-shaped base 31. The surface of the connecting plate 33 passes through the groove and slides left and right. This design provides stable guidance for the left and right movement of the connecting plate 33. When the hydraulic cylinder 32 is started, its output end will push or pull the connecting plate 33 to move left and right in the groove. A connecting rod 34 is fixedly connected to the left side of the connecting plate 33 near the top. The other end of the connecting rod 34 is fixedly connected to a heating block 35. Therefore, the movement of the connecting plate 33 will drive the connecting rod 34 and the heating block 35 to move left and right together. A support plate 36 is fixedly connected to the bottom left side of the L-shaped base 31. A hole matching the connecting rod 34 is opened near the top of the left side of the support plate 36. The surface of the connecting rod 34 passes through the hole and slides left and right. The support plate 36 supports the connecting rod 34, ensuring its stability as it moves the heating block 35 left and right, preventing wobbling and ensuring the heating block 35 accurately approaches or moves away from the brake disc. The power supply body 37 is fixedly connected to the bottom right side of the L-shaped base 31. The power supply body 37 is connected to the heating block 35 via a power cable, providing power to the heating block 35. When the brake disc begins to rotate under the action of the rotating clamping mechanism 2, the hydraulic cylinder 32 is controlled to push the connecting plate 33 to the left, thereby moving the connecting rod 34 and the heating block 35 to the left, bringing the heating block 35 closer to the surface of the brake disc. The heating block 35 generates heat after being energized, heating the surface of the rotating brake disc to achieve heat treatment. After heat treatment, the hydraulic cylinder 32 is controlled to pull the connecting plate 33 to the right, moving the heating block 35 away from the brake disc, completing the entire heat treatment process.
