Description

Technical Field

[0001] The utility model relates to the technical field of automobile wheel hub cooling clamping, in particular to a cooling device for automobile wheel hub machining. Background Technique

[0002] The cooling device for automobile wheel hub machining is mainly to ensure that the wheel hub material will not be damaged or deformed due to high temperature during the machining process. The traditional cooling methods mainly include air cooling and water cooling. The air cooling method blows air to the wheel hub surface through a fan, and uses air convection to take away heat. This method is simple and easy to implement, but the heat dissipation effect is limited and it is difficult to meet the requirements of high-precision machining. The water cooling method sprays cooling water to the wheel hub surface through a water circulation system, and uses the heat conduction and evaporation heat absorption of water to reduce the temperature of the wheel hub. Although the water cooling method has a better heat dissipation effect, there are problems such as large water resource consumption and environmental pollution.

[0003] According to CN202222168938.7 disclosed in the Chinese patent, in this application document, through the setting of the moving frame, the wheel hub to be cooled is placed. Through the push of the cylinder on the moving frame, the wheel hub can move into the reservoir for cold zone cooling operation, thus avoiding manually placing the wheel hub into the reservoir, saving manpower and improving the safety protection effect on workers when cooling the wheel hub;

[0004] Although the moving frame in the application document can effectively handle the problem of inconvenient operation, however, when in use, different specifications and models of wheel hubs require different fixtures for clamping. The adaptability of the existing fixtures is poor and they cannot adapt to wheel hubs of various specifications and models, so it is necessary to frequently replace the fixtures, increasing the production cost and operation complexity. For this reason, we propose a cooling device for automobile wheel hub machining. Content of the Utility Model

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0022] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0023] Please refer to Figures 1-3 , a cooling device for machining automotive wheel hubs, including a base 1, first support rods 2, support blocks 3, hydraulic rods 4, coolant tanks 5, coolant pipes 6, and automotive wheel hubs 18. Four first support rods 2 are fixedly connected to the top of the base 1, a support block 3 is fixedly connected to the top of the four first support rods 2, a hydraulic rod 4 is fixedly connected to the bottom of the support block 3, a coolant tank 5 is fixedly connected to the outside of the hydraulic rod 4, a coolant pipe 6 is fixedly connected to the outside of the coolant tank 5, and an automotive wheel hub 18 is movably connected between the top of the base 1 and the four first support rods 2. Further included are:

[0024] The clamping structure is arranged at the bottom of the hydraulic rod 4 and is used to fix the vehicle wheel hub 18. The clamping structure includes a third support rod 19, a clamping block 20 and a fixing shaft 21. Three groups of third support rods 19 are fixedly connected to the top of the base 1. A clamping block 20 is movably connected between the three groups of third support rods 19, and the clamping block 20 is in an "I" shape. Fixing shafts 21 are inserted at the corresponding positions of the clamping block 20 and the three groups of third support rods 19. The outer side of the clamping block 20 is movably connected to the outer side of the vehicle wheel hub 18. When in use, the "I"-shaped design of the clamping block 20 enables it to be movably connected between the third support rods 19. The fixing shaft 21 passes through the corresponding positions of the clamping block 20 and the third support rods 19, enabling the clamping block 20 to rotate around the fixing shaft 21. When it is necessary to clamp the vehicle wheel hub 18, the outer side of the clamping block 20 is movably connected to the outer side of the vehicle wheel hub 18 to form a surrounding clamping structure;

[0025] The adjusting structure is arranged at the top of the base 1 and is used to adjust the clamping force on the vehicle wheel hub 18.

[0026] Furthermore, a pressing block 17 is movably connected to the top of the vehicle wheel hub 18. Two groups of clamping blocks 16 are fixedly connected to the outer side of the pressing block 17. The other ends of the two groups of clamping blocks 16 are fixedly connected to a connecting rod 11.

[0027] Furthermore, the adjusting structure includes a second sliding groove 12 and a threaded rod 13. A second sliding groove 12 is opened at one end of the connecting rod 11, and the inner wall of the second sliding groove 12 is movably connected to a threaded rod 13.

[0028] Furthermore, a nut 14 is movably connected to the corresponding position at the top of the threaded rod 13 and the top of the connecting rod 11. A spring 15 is sleeved on the outer side of the threaded rod 13 and the corresponding position at the bottom of the connecting rod 11. The bottom of the threaded rod 13 is fixedly connected to the top of the base 1. Through the nut 14, due to the threaded fit between the nut 14 and the top of the threaded rod 13, the nut 14 will move up and down on the threaded rod 13. The movement of the nut 14 will drive the lifting of the movable rod 10, thereby adjusting the clamping force of the pressing block 17 and the clamping blocks 16 on the vehicle wheel hub 18. The spring 15 is used to provide an additional clamping force to ensure that the vehicle wheel hub 18 remains stable during the processing. When the nut 14 moves upward, the spring 15 is compressed to provide a downward elastic force; when the nut 14 moves downward, the spring 15 releases the elastic force to help the movable rod 10 reset.

[0029] Furthermore, two sets of second support rods 7 are fixedly connected to the top of the base 1. The tops of the two sets of second support rods 7 are fixedly connected with a slider 8. A first sliding groove 9 is formed in the top of the slider 8. The other end of the movable rod 10 is connected to the slider 8. Therefore, when the slider 8 moves in the first sliding groove 9, the movable rod 10 will also move accordingly. The design of the first sliding groove 9 allows the movable rod 10 to perform stable horizontal movement, ensuring that the pressing block 17 and the clamping block 16 can accurately clamp the automobile wheel hub 18.

[0030] Furthermore, the other end of the connecting rod 11 is fixedly connected with a movable rod 10. The top of the movable rod 10 is movably connected to the inner wall of the first sliding groove 9. When the movable rod 10 moves, the clamping block 16 and the pressing block 17 are driven by the connecting rod 11 to approach or move away from the automobile wheel hub 18 together, realizing the clamping or loosening operation.

[0031] Working principle:

[0032] During use, the clamping block 20 is designed in an "I" shape and can be movably connected between the third support rods 19. The fixed shaft 21 passes through the corresponding positions of the clamping block 20 and the third support rods 19, enabling the clamping block 20 to rotate around the fixed shaft 21. When it is necessary to clamp the automobile wheel hub 18, the outer side of the clamping block 20 is movably connected to the outer side of the automobile wheel hub 18 to form a surrounding clamping structure. When the movable rod 10 moves, the clamping block 16 and the pressing block 17 are driven by the connecting rod 11 to approach or move away from the automobile wheel hub 18 together, realizing the clamping or loosening operation. Through the nut 14, due to the threaded fit between the nut 14 and the top of the threaded rod 13, the nut 14 will move up and down on the threaded rod 13. The movement of the nut 14 will drive the lifting of the movable rod 10, thereby adjusting the clamping force of the pressing block 17 and the clamping block 16 on the automobile wheel hub 18. The other end of the movable rod 10 is connected to the slider 8. Therefore, when the slider 8 moves in the first sliding groove 9, the movable rod 10 will also move accordingly. The design of the first sliding groove 9 allows the movable rod 10 to perform stable horizontal movement, ensuring that the pressing block 17 and the clamping block 16 can accurately clamp the automobile wheel hub 18. The spring 15 is used to provide an additional clamping force to ensure that the automobile wheel hub 18 remains stable during the processing. When the nut 14 moves upward, the spring 15 is compressed to provide a downward elastic force. When the nut 14 moves downward, the spring 15 releases the elastic force to help the movable rod 10 reset.
