[0002] A grinder is a machine tool that uses abrasive tools to grind the surface of a workpiece. Most grinders use high-speed rotating grinding wheels for grinding.

[0020] During operation, through the cooperation of the first limit assembly and the second limit assembly, when supporting the rod-type products, the first limit assembly can be used to limit the front and rear directions of the end that needs to be polished, and the second support seat 7 can be used to support the other end of the rod-type products. At the same time, the second limit assembly can be used to limit the upper end of the rod-type products. At this time, the rod-type products can be more stably located in the first support seat 3 and the second support seat 7, and the rod-type products are not prone to tilting or deviation. In this way, the five-axis linkage CNC tool grinder can be used to perform more stable processing operations on the rod-type products.

[0021] Furthermore, two groups of first limiting components are provided, and are symmetrically distributed front to back, and are both installed on the upper end of the first supporting seat 3. The first limiting components include a first limiting wheel 20, a fixed seat 22, a rotating frame 21, a fixed shaft 23, a rotating block 24, a telescopic rod 25 and a spring 26. The upper end of the first supporting seat 3 is fixedly connected to the fixed seat 22, the spring 26 and the telescopic rod 25. The outer end of the fixed seat 22 is rotatably connected to the rotating frame 21. The interior of the rotating frame 21 is rotatably connected to the first limiting wheel 20. The interior of the rotating frame 21 is fixedly connected to the fixed shaft 23. The circumferential surface of the fixed shaft 23 is fixedly connected to the rotating block 24. The ends of the telescopic rod 25 and the spring 26 away from the first supporting seat 3 are fixedly connected to the rotating block 24.

[0022] During work, place the end of the bar product that needs to be processed in the first supporting seat 3. Before placing it, it is necessary to rotate the rotating frame 21 along the fixed seat 22 so that the rotating frame 21 rotates in the direction away from the first supporting seat 3. At the same time, the spring 26 and the telescopic rod 25 are stretched until the rotating frame 21 drives the first limiting wheel 20 to rotate to a suitable position, and then the bar product can be placed. After the placement is completed, slowly release the rotating frame 21. At this time, under the action of the spring 26, the rotating frame 21 can drive the first limiting wheel 20 to rotate along the fixed seat 22 in the direction close to the bar product until the first limiting wheel 20 tightly squeezes the bar product, so that the front and rear directions of the bar product can be limited.

[0023] Furthermore, the second limiting assembly includes a movable plate 27, a sliding hole 16, a movable frame 15, a second limiting wheel 12, a connecting rod 10 and a fixed rod 11. A sliding hole 16 is provided on the front end surface of the fixed frame 9. The sliding hole 16 is slidably connected to the movable frame 15 inside. The movable frame 15 is rotatably connected to the second limiting wheel 12 inside. The second limiting wheel 12 is located at the upper end of the second support seat 7. The upper end of the movable frame 15 is rotatably connected to the connecting rod 10. A movable plate 27 is provided on the top of the fixed frame 9. The movable plate 27 is slidably connected to the fixed frame 9. The movable plate 27 is fixedly connected to the fixed rod 11 inside. The fixed rod 11 passes through the connecting rod 10, and the connecting rod 10 and the fixed rod 11 are rotatably connected.

[0024] During operation, after the placement of the rod-like product is completed, one end of the rod-like product is located in the first support seat 3, and the other end is located in the second support seat 7. With the cooperation of the first support seat 3 and the second support seat 7, the rod-like product can be stably supported. Then the driving component is controlled to operate so that the movable plate 27 drives the fixed rod 11 to move backward, and then the connecting rod 10 rotates and moves. Under the action of the connecting rod 10, the movable frame 15 drives the second limiting wheel 12 to gradually move downward until the second limiting wheel 12 is pressed on the upper end of the rod-like product. In this way, with the cooperation of the second limiting wheel 12 and the second support seat 7, the upper and lower directions of the rod-like product can be limited.

[0025] Furthermore, the driving assembly includes a support plate 13 and an electric push rod 14 . The two fixing frames 9 are fixedly connected via the support plate 13 . The electric push rod 14 is fixedly connected inside the support plate 13 . The output end of the electric push rod 14 is fixedly connected to the moving plate 27 .

[0026] During operation, the electric push rod 14 is controlled to operate, so as to drive the movable plate 27 to move forward and backward along the fixed frame 9 .

[0027] Furthermore, the displacement adjustment component includes a bearing seat 18, a threaded rod 8 and a motor 17. The upper end of the fixed plate 1 is fixedly connected to the bearing seat 18. Two bearing seats 18 are provided and are symmetrically distributed on the left and right. The threaded rod 8 is rotatably connected inside the two bearing seats 18. The threaded rod 8 penetrates the second movable platform 6 to the right, and the second movable platform 6 is threadedly connected to the threaded rod 8. The upper end of the fixed plate 1 is fixedly connected to the motor 17 through a support frame, and the output shaft end of the motor 17 is fixedly connected to the threaded rod 8.

[0028] During operation, the motor 17 can drive the threaded rod 8 to rotate. Under the action of the threaded rod 8, the second movable platform 6 can drive the first movable platform 5 to move left and right along the slide rail 4, which will change the distance between the second movable platform 6 and the support platform 2, and then change the distance between the first support seat 3 and the second support seat 7. At this time, it is convenient to use the first support seat 3 and the second support seat 7 to support rod products of different lengths.

[0029] Furthermore, a guide rod 19 is fixedly connected to the rear end of the fixed frame 9 , the movable frame 15 extends backward and passes through the sliding hole 16 , and the guide rod 19 penetrates the movable frame 15 , and the movable frame 15 is slidably connected to the guide rod 19 .

[0030] During operation, under the action of the guide rod 19, the movable frame 15 can be lifted and lowered more stably.

[0031] Working principle:

[0032] The fixed plate 1 is installed in the five-axis linkage CNC tool grinder, and then the displacement adjustment component is controlled to operate according to the length of the bar product. Under the action of the displacement adjustment component, the distance between the first support seat 3 and the second support seat 7 matches the length of the bar product. Then, the rotating frame 21 is rotated along the fixed seat 22 to make the rotating frame 21 rotate away from the first support seat 3. At the same time, the spring 26 and the telescopic rod 25 are stretched until the rotating frame 21 drives the first limiting wheel 20 to rotate to a suitable position, and then the end of the bar product to be processed can be placed in the first support seat 3. After the placement is completed, the rotating frame 21 is slowly released. At this time, under the action of the spring 26, the rotating frame 2 1 drives the first limiting wheel 20 to rotate along the fixed seat 22 toward the direction of the bar product until the first limiting wheel 20 tightly squeezes the bar product, so that the front and rear directions of the bar product can be limited. At the same time, the end and the middle and rear ends of the bar product will also be located in the two second support seats 7, and then the driving component is controlled to operate. Under the action of the second driving component, the second limiting component can limit the upper end of the other end of the bar product. At this time, the bar product can be more stably located in the first support seat 3 and the second support seat 7, and the bar product is not prone to tilting or offsetting. In this way, the five-axis linkage CNC tool grinder can be used to perform more stable processing operations on the bar product.
