Description

Technical Field

[0001] This utility model relates to the field of engine cooler manufacturing, and more specifically, to an engine cooler processing fixture. Background Technology

[0002] The engine cooler is a crucial component of the engine cooling system, its primary function being heat dissipation to ensure the engine is not damaged by overheating during normal operation. The engine cooler works by circulating coolant between the engine and the radiator, transferring heat generated by the engine to the radiator, and then dissipating the heat into the atmosphere through a fan and airflow, thus maintaining the engine at a suitable operating temperature. In this process, the cooler plays a critical role in heat dissipation. The production process of engine coolers requires the use of fixtures to ensure that the various components of the cooler maintain the correct position and shape during processing and assembly. Using fixtures improves production efficiency, ensures product quality, and reduces errors from manual operation.

[0003] Most existing engine cooler fixtures have non-replaceable chucks, meaning the fixture can only be used for specific models, sizes, and shapes of engine coolers. When different models of coolers need to be produced, the entire fixture needs to be replaced, which increases production costs and complexity. Furthermore, changing the fixture requires workers to spend time disassembling and replacing the entire fixture, which is not only cumbersome but also increases downtime and reduces production efficiency. Therefore, we propose an improved engine cooler machining fixture. Utility Model Content

[0004] To address the problems mentioned above, this utility model provides the following technical solution:

[0005] An engine cooler machining fixture includes a worktable. A first drive mechanism is provided at the bottom of the worktable. The output end of the first drive mechanism is connected to a first bidirectional lead screw. A movable frame is threaded to both ends of the first bidirectional lead screw. The movable frame is slidably connected to the worktable. A mounting base is fixedly installed on the movable frame. A second drive mechanism is provided on the side wall of the mounting base. The output end of the second drive mechanism is connected to a second bidirectional lead screw. An L-shaped locking rod is threaded to both ends of the second bidirectional lead screw. A mounting block is provided on the front of the mounting base. A clamping head is fixedly installed on the front of the mounting block. A connecting groove is provided on the mounting base. A connecting rod is fixedly installed on the back of the mounting block. The connecting groove matches the connecting rod. A locking groove is provided on the connecting rod. The locking groove matches the L-shaped locking rod. A handle is fixedly installed on the mounting block.

[0006] As a preferred technical solution of this utility model, the first driving mechanism includes a first brake reduction motor fixedly installed at the bottom of the workbench, and the output end of the first brake reduction motor is fixedly connected to a first bidirectional lead screw.

[0007] As a preferred technical solution of this utility model, the second drive mechanism includes a second brake reduction motor fixedly installed on the side wall of the mounting base, and the output end of the second brake reduction motor is fixedly connected to a second bidirectional lead screw.

[0008] As a preferred technical solution of this utility model, sliders are fixedly installed on both inner side walls of the movable frame, and slide rails are provided on both side walls of the worktable, with the slide rails matching the sliders.

[0009] As a preferred technical solution of this utility model, a switch group is provided on the front of the workbench, and the switch group is electrically connected to the first brake reduction motor and the second brake reduction motor respectively.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0011] This invention utilizes a second braking reduction motor. The output of the second braking reduction motor drives a second bidirectional lead screw to rotate. The rotation of the second bidirectional lead screw causes two L-shaped locking rods to move simultaneously, inserting them into the locking grooves on the connecting rod. This allows workers to quickly change the chuck when producing different models of coolers without replacing the entire fixture, reducing downtime and improving production efficiency. It solves the problem in existing technologies where replacing the entire fixture is required when producing different models of coolers, which increases production costs and complexity. Furthermore, workers need to spend time disassembling and replacing the entire fixture, which is not only cumbersome but also increases downtime and reduces production efficiency.

The output end of the first driving mechanism is connected to a first bidirectional lead screw 12. The output end of the first driving mechanism drives the first bidirectional lead screw 12. A movable frame 2 is threadedly connected to the threads at both ends of the first bidirectional lead screw 12. The rotation of the first bidirectional lead screw 12 drives the movable frame 2 to move. The movable frame 2 is slidably connected to the worktable 1. A mounting base 3 is fixedly installed on the movable frame 2. The movement of the movable frame 2 drives the mounting base 3. A second driving mechanism is provided on the side wall of the mounting base 3. The output end of the second driving mechanism is connected to a second bidirectional lead screw 4. The output end of the second driving mechanism drives the second bidirectional lead screw 4 to rotate. The second bidirectional lead screw 4 has L-shaped locking rods 5 threaded at both ends. Rotation of the second bidirectional lead screw 4 drives the two L-shaped locking rods 5 to move simultaneously. The mounting base 3 has a mounting block 6 on its front side. The mounting base 3 drives the mounting block 6 to move. A clamping head 7 is fixedly installed on the front side of the mounting block 6. The mounting block 6 drives the clamping head 7 to move, so that the clamping head 7 clamps the engine cooler, which can then be processed. The mounting base 3 has a connecting groove 8. A connecting rod 17 is fixedly installed on the back of the mounting block 6. The connecting groove 8 matches the connecting rod 17. A locking groove 9 is opened on the connecting rod 17. The locking groove 9 matches the L-shaped locking rod 5. A handle 10 is fixedly installed on the mounting block 6. By holding the handle 10, the mounting block 6 can be lifted.

[0028] Specifically, the first drive mechanism includes a first brake reduction motor 13 fixedly installed at the bottom of the workbench 1. The output end of the first brake reduction motor 13 is fixedly connected to the first bidirectional lead screw 12. The output end of the first brake reduction motor 13 drives the first bidirectional lead screw 12 to rotate.

[0029] Specifically, the second drive mechanism includes a second brake reduction motor 11 fixedly installed on the side wall of the mounting base 3. The output end of the second brake reduction motor 11 is fixedly connected to the second bidirectional lead screw 4, and the output end of the second brake reduction motor 11 drives the second bidirectional lead screw 4 to rotate.

[0030] Specifically, sliders 14 are fixedly installed on both inner side walls of the movable frame 2, and slide rails 15 are provided on both side walls of the worktable 1. The movable frame 2 drives the sliders 14 to slide along the slide rails 15, and the slide rails 15 and sliders 14 are matched. The above design, through the design of the slide rails 15 and sliders 14, enables the movable frame 2 to move smoothly.

[0031] Specifically, a switch group 16 is provided on the front of the workbench 1, and the switch group 16 is electrically connected to the first brake reduction motor 13 and the second brake reduction motor 11 respectively.

Their structural principle and usage method are existing technologies and will not be described in detail here.

[0033] Working principle: When in use, first remove the original clamping head 7, then select the appropriate clamping head according to the different models of coolers. Next, hold the handle 10 to lift the mounting block 6. The mounting block 6 drives the connecting rod 17 and inserts the connecting rod 17 into the connecting groove 8. Then, start the second brake reduction motor 11. The output end of the second brake reduction motor 11 drives the second double-acting screw 4 to rotate. The rotation of the second double-acting screw 4 drives the two L-shaped locking rods 5 to move simultaneously, so that the L-shaped locking rods 5 are inserted into the locking grooves 9 on the connecting rod 17. In this way, when different models of coolers need to be produced, the workers can quickly change the clamping head without having to change the entire fixture, reducing downtime and thus improving production efficiency.

[0034] Place the engine cooler between the two clamping heads 7, then start the first brake reduction motor 13. The output end of the first brake reduction motor 13 drives the first double-acting lead screw 12 to rotate. The rotation of the first double-acting lead screw 12 drives the moving frame 2 to move. The moving frame 2 drives the slider 14 to slide along the slide rail 15. At the same time, the moving frame 2 drives the mounting base 3 to move. The mounting base 3 drives the mounting block 6 to move. The mounting block 6 drives the clamping head 7 to move, so that the clamping head 7 clamps the engine cooler, and then subsequent processing can be carried out.
