Description

Technical Field

[0001] This utility model relates to the field of lifting fixtures, and in particular to a high-temperature quenched lifting fixture for brake discs. Background Technology

[0002] In the automotive parts manufacturing industry, brake discs are a critical safety component, and their processing quality directly affects the vehicle's braking performance. High-temperature quenching is a core process for improving the strength and wear resistance of brake discs. This process requires heating the brake discs to a specific high temperature followed by rapid cooling. During this process, because the brake discs are at a high temperature, manual handling not only poses significant safety hazards but also makes it difficult to ensure operational precision. Therefore, specialized lifting fixtures are needed to complete the transfer and positioning of the brake discs before and after quenching.

[0003] Currently, commercially available lifting fixtures for high-temperature quenching of brake discs typically consist of a bracket, grippers, a drive cylinder, and a clamping plate. Their working principle involves the drive cylinder providing power to open and close the grippers, allowing them to engage with the clamping plate to clamp and release the brake disc. During clamping, the friction generated between the grippers and the clamping plate stably holds the brake disc, facilitating its transfer between the quenching equipment and the conveying device.

[0004] However, in practical use, the distance adjustment between the jaws and the clamping plate in existing high-temperature quenching and lifting fixtures for brake discs is very complicated. Operators often have to use additional tools to disassemble, adjust, and reinstall the relevant connecting parts, which not only consumes a lot of time and manpower, but also makes it difficult to accurately control the distance between the two. Improper distance can easily lead to unstable clamping of the brake disc or damage due to excessive clamping. Therefore, a high-temperature quenching and lifting fixture for brake discs is proposed to solve the above problems. Utility Model Content

Detailed Implementation

[0033] 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.

[0034] Reference Figure 1 - Figure 3 This utility model provides an embodiment of a high-temperature quenching lifting fixture for brake discs, comprising multiple lifting brackets 1. The lifting brackets 1 are used to adjust the height of the entire fixture to adapt to different working scenarios. Each lifting bracket 1 is fixedly connected to a rotating shaft 2 at its bottom. The rotating shaft 2 is used to connect the lifting bracket 1 to a fixing block 3, so that the fixing block 3 can rotate at a certain angle around the rotating shaft 2, increasing the flexibility of the fixture. Each rotating shaft 2 is fixedly connected to two ends of a fixing block 3, which is used to fix a clamping plate 4 and stably support the clamping plate 4 below the rotating shaft 2. Multiple clamping plates 4 are fixedly connected to the bottom of the multiple fixing blocks 3. The clamping plates 4 are used to cooperate with the grippers 5 to clamp the brake disc, providing support and positioning for the grippers 5. An adjustment component is provided on one side of the multiple clamping plates 4.

[0035] The adjustment assembly includes a second rotating shaft 16, one end of which is rotatably connected to one side of the clamping plate 4. The second rotating shaft 16 is used to transmit the rotational force of the handle 19, driving the transmission assembly to operate. A transmission assembly is provided at one end of the second rotating shaft 16, which is used to fix the gripper 5 after adjusting its position to prevent the gripper 5 from shifting during clamping. A connecting rod 17 is fixedly connected to the other end of the second rotating shaft 16. The connecting rod 17 is used to connect the second rotating shaft 16 and the third rotating shaft 18, transmitting the rotation of the second rotating shaft 16 to the third rotating shaft 18. The third rotating shaft 18 is fixedly connected to the other end of the connecting rod 17, connecting the connecting rod 17 and the handle 19, allowing the handle 19 to rotate around it, facilitating the operator to apply force. The handle 19 is rotatably connected to the outer wall of the third rotating shaft 18, allowing the operator to grip it. Rotating the handle 19 drives the entire adjustment assembly to operate. The transmission assembly includes a worm gear 15 and fixed rods 21. One end of the worm gear 15 is fixedly connected to one end of a rotating shaft 16. The worm gear 15 rotates in cooperation with a worm wheel 14, transmitting the rotational force of the rotating shaft 16 to the worm wheel 14. Multiple fixed rods 22 are fixedly connected at both ends to the inner wall of the clamping plate 4. The fixed rods 22 are used to fix the worm wheel 14 and the gear 13, enabling them to rotate stably. The outer wall of the fixed rods 22 is fixedly connected to the worm wheel 14 and the gear 13. The worm wheel 14 meshes with the worm gear 15, and the worm wheel 14 and worm gear 15 cooperate to reduce speed and improve adjustment accuracy. The gear 13 cooperates with the rack 11 to convert rotation into linear motion, driving the rack 11 to move. A slot 21 is provided at the bottom of the clamping plate 4. The slot 21 provides space for the sliding of the fixed plate 12, allowing the fixed plate 12 to move stably along the slot 21. Multiple fixed plates 12 are slidably connected to the inner wall of the slot 21. The fixed plates 12 are used to fix the rack 11, driving the rack 11 to move synchronously. A rack 11 is fixedly connected to the inner wall of multiple fixed plates 12. The rack 11 meshes with the gear 13. The rack 11 moves linearly under the drive of the gear 13, thereby driving the gripper 5 to move. A gripper 5 is fixedly connected to one end of the rack 11. The gripper 5 cooperates with the clamping plate 4 to clamp the brake disc, realizing the gripping and transfer of the brake disc. A temperature control component is provided on one side of the gripper 5. The temperature control component is used to cool down the gripper 5 when it is working at high temperature, thereby extending the service life of the gripper 5.

[0036] Reference Figure 1 , Figure 4 and Figure 5The temperature control component includes a water tank 9, which is located on one side of the clamp 5. The water tank 9 is used to store cooling water and provide a water source for water circulation. A locking block 10 is fixedly connected to one side of the clamp 5. The locking block 10 is used to fix the water tank 9 so that the water tank 9 can be stably installed on one side of the clamp 5. The water tank 9 and the locking block 10 are engaged. A water inlet pipe 6 is threadedly connected to one side of the water tank 9. The water inlet pipe 6 is used to transport the cooling water in the water tank 9 to the inside of the clamp 5. A water outlet pipe 7 is threadedly connected to the other side of the water tank 9. The water outlet pipe 7 is used to send the water that has absorbed heat in the clamp 5 back to the water tank 9 to form a water circulation. The inlet pipe 6 is a two-ended pipe. One end of the pipe is connected to the water tank 9 and the input end of the solenoid valve 8, respectively. The other end of the pipe is connected to the output end of the solenoid valve 8 and extends into the inside of the clamp 5. At the same time, an outlet pipe 7 is fixedly connected to it. The other end of the outlet pipe 7 extends to the outside of the clamp 5 and is connected to the inside of the water tank 9. A fixing bracket 20 is fixedly connected to one side of the solenoid valve 8. The fixing bracket 20 is used to fix the solenoid valve 8 and prevent the solenoid valve 8 from shaking during operation. The other end of the fixing bracket 20 is fixedly connected to the bottom of the water tank 9. The inlet pipe 6 and the outlet pipe 7 cooperate to form a water flow channel inside the clamp 5, so that the cooling water can flow in the clamp 5 and carry away the heat.

[0037] Working principle: During the adjustment of the distance between the jaw 5 and the clamping plate 4, the worm gear 15, which is fixedly connected to one end of the rotating shaft 16, is driven to rotate by manually rotating the handle 19. Since the worm gear 15 meshes with the turbine 14, the turbine 14 is fixedly connected with the gear 13, and the gear 13 meshes with the rack 11, the handle 19 will drive the rack 11 to move inside the multiple fixed plates 12 through the worm gear 15 and the turbine 14 during the rotation. Since the rack 11 is fixedly connected to one side of the jaw 5, the external force can rotate the handle 19 to achieve the purpose of adjusting the distance between the jaw 5 and the clamping plate 4. This solves the problem that the distance adjustment between the jaws 5 of the traditional lifting clamp is inconvenient and requires the replacement of the clamp, and enhances the convenience and applicability of the lifting clamp.

[0038] When the gripper 5 is working at high temperature, the solenoid valve 8 is activated, which drives the water inlet pipe 6 to draw water from the water tank 9. The water enters the inside of the gripper 5 through a pipe on one side, then splits into two pipes on the other side, and finally flows out through the water outlet pipe 7 on the other side and back into the water tank 9. This circulating water system continuously cools the entire gripper 5 when it is working at high temperature, which solves the problem of surface oxidation and wear that shortens the life of traditional clamps when working at high temperature, enhances the continuous working ability of the clamp, and improves work efficiency.

[0039] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
