Description

Technical Field

[0001] This utility model relates to the field of cable routing technology, and in particular to a grinding machine for round dies. Background Technology

[0002] A round die is a thread-machining tool used to machine or correct external threads. The round die has an overall ring-shaped structure with multiple tap walls spaced apart on its inner circumference. Each tap wall has multiple high-strength tap grooves tapped longitudinally. The cutting force of these tap grooves is used to machine the external threads of bolts. After tapping the tap grooves of the round die, burr-like tap edges remain on the resulting grooves, requiring precise grinding of the tap edges using a grinding machine.

[0003] Existing grinding machines are equipped with grinding wheels, most of which are fixed in design. When operators need to perform tap groove grinding, they need to manually adjust the placement angle of the round die to adapt to the specific grinding angle required for different tap groove specifications. However, manual operation may introduce errors, resulting in unstable processing accuracy. Furthermore, operators need to spend extra time and effort to adjust and calibrate the equipment to ensure the accuracy of the grinding operation, thereby reducing the processing efficiency of the equipment.

[0022] 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.

[0023] Reference Figures 1-3 This utility model provides an embodiment of a grinding machine for round dies, comprising a support platform 1, a support column 5 fixedly connected to the top of the support platform 1, a slide rod 8 slidably connected to one side of the support column 5, an electric push rod 6 fixedly connected to the other side of the support column 5, a connecting plate 7 fixedly connected to the output end of the electric push rod 6, one side of the connecting plate 7 fixedly connected to the top of the slide rod 8, a fixing plate 9 fixedly connected to the bottom of the slide rod 8, a ball bearing 19 provided at the bottom of the fixing plate 9, a limit slider 11 fixedly connected to the bottom of the fixing plate 9, a limit groove 13 formed inside the ball bearing 19, and a limit slider 11 slidably connected to the outer wall of the limit slider 11. The inner wall of groove 13 has a ball 19 that is slidably connected to a limiting slider 18. A limiting groove 12 is opened inside the ball 19. The outer wall of the limiting slider 18 is slidably connected to the limiting groove 12. A rotating ring 17 is rotatably connected to the bottom of the fixed plate 9. A rotating ring 16 is rotatably connected to the bottom of the fixed plate 9. A motor 14 is fixedly connected to the bottom of the fixed plate 9. A motor 15 is fixedly connected to the bottom of the fixed plate 9. One side of the rotating ring 17 is fixedly connected to the output end of the motor 14. One side of the rotating ring 16 is fixedly connected to the output end of the motor 15. A grinder 10 is fixedly connected to the bottom of the limiting slider 18.

[0024] Specifically, when finely adjusting the grinding angle of the circular die, firstly, motor 14 is started. Motor 14 is connected to rotating ring 17 via a synchronous belt drive system. When rotating ring 17 starts to rotate under the drive of motor 14, the limiting slider 18 installed inside it moves accordingly. The limiting slider 18 slides along the limiting groove 12 inside the ball 19. Through this transmission process, the angle adjustment of the grinder 10 in the lateral direction is achieved. At the same time, motor 15 starts to work, which can drive rotating ring 16 to rotate. When rotating ring 16 rotates, the pushing surface will contact the limiting slider 18 and apply a pushing force. Under the push of rotating ring 16, the limiting slider 18 drives the ball 19 to move. 9 rotates. When the ball 19 rotates, the limiting slider 11 slides in the rotating ring 17 inside the ball 19. This structural design allows the ball 19 to rotate longitudinally, realizing the adjustment of the longitudinal angle of the grinder 10. With the coordinated cooperation of the motor 14 and the motor 15, by controlling the linkage of components such as the rotating ring 16, the rotating ring 17, the limiting slider 11 and the limiting slider 18, the deflection angle of the grinder 10 in three-dimensional space can be precisely adjusted. Whether it is grinding the plane of the round die or trimming the cutting edge of the complex curved surface, this adjustment system can quickly and accurately adjust the grinder 10 to the required angle, ensuring high precision and high quality of the grinding operation and meeting the processing needs of round dies of different specifications.

[0025] Reference Figure 1 A heat dissipation grille 2 is fixedly connected to one side of the inside of the support platform 1, and a control panel 3 is fixedly connected to one side of the inside of the support platform 1.

[0026] Specifically, the equipment is equipped with a heat dissipation grille 2, which can better dissipate heat and prevent overheating from damaging internal parts, thus effectively increasing the service life of the equipment. At the same time, a control panel 3 is provided on the support platform 1, which can make the equipment more convenient to operate and effectively reduce the difficulty of operating the equipment.

[0027] Reference Figure 1 and Figure 4 A processing table 4 is fixedly connected to the top of the support platform 1. A rotating plate 22 is rotatably connected inside the processing table 4. A motor 23 is fixedly connected inside the processing table 4. The bottom of the rotating plate 22 is fixedly connected to the output end of the motor 23. A slide rail 24 is fixedly connected inside the processing table 4. A moving block 27 is slidably connected to the outer wall of the slide rail 24. A pull rod 26 is rotatably connected inside the moving block 27. One side of the pull rod 26 is rotatably connected inside the rotating plate 22. A sliding groove 21 is opened inside the processing table 4. A connecting block 25 is fixedly connected to the top of the moving block 27. The outer wall of the connecting block 25 is slidably connected to the inside of the sliding groove 21. A clamping block 20 is fixedly connected to the top of the connecting block 25.

[0028] Specifically, when performing the grinding operation of the round die, the operator first places the round die to be processed horizontally on the top of the processing table 4. Then, the motor 23 starts running, driving the rotating plate 22 to rotate, thereby pulling the pull rod 26. The other end of the pull rod 26 is connected to the moving block 27 through a joint bearing. This connection method allows the pull rod 26 to swing at a small angle when transmitting the pulling force, ensuring smooth movement. This drives multiple moving blocks 27 to slide towards the center along the linear guide rail inside the processing table 4. The moving blocks 27 are rigidly connected to the connecting block 25. When the moving blocks 27 slide towards the center, the clamping blocks 20 move synchronously through the connecting block 25. The three clamping blocks 20 position and clamp the round die from different directions, ensuring that the round die remains accurately fixed during the grinding process. After the round die is positioned and clamped, the slide rod 8 slides downward in the vertical direction under the drive of the electric push rod 6, driving the grinder 10 to penetrate into the round die for grinding.

[0029] Working principle: When sharpening a round die, the die can be placed on top of the machining table 4. The rotating plate 22 is controlled by motor 23 to rotate. The rotation of the rotating plate 22 synchronously pulls the pull rod 26, causing the pull rod 26 to simultaneously drive multiple moving blocks 27 to slide towards the center. The moving blocks 27, through the connecting block 25, drive the clamping block 20 on top of the machining table 4 to move towards the center, thereby positioning and clamping the round die on the machining table 4. Then, the electric push rod 6 drives the sliding rod 8 downwards through the connecting plate 7, causing the grinder 10 at the bottom of the sliding rod 8 to grind the round die. When adjusting the sharpening angle, the rotating ring can be driven by motor 14. When the rotating ring 17 rotates, it will drive the limiting slider 18 to slide along the limiting groove 12 inside the ball 19, thereby adjusting the angle laterally. At the same time, the rotating ring 16 can be driven by the motor 15 to rotate, and the rotating ring 16 pushes the limiting slider 18, which will drive the ball 19 to rotate. The fixed limiting slider 11 can slide in the rotating ring 17 inside the ball 19, thereby rotating the ball 19 longitudinally. This controls the adjustment of the longitudinal angle of the limiting slider 18. With the cooperation of both, the deflection angle of the grinder 10 can be controlled.

[0030] 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.
