[0002] With the continuous development of industrial manufacturing, the high-precision positioning performance of mechanical systems has become increasingly important. Ball screw technology has attracted much attention due to its excellent high-precision positioning performance. Ball screw technology is a transmission method based on rolling friction, which achieves rotation and linear motion through the contact between the ball and the threaded screw. Compared with traditional screw transmission, ball screw technology reduces sliding friction, improves transmission efficiency and accuracy, has low return error and high repeatability, and can achieve precise position control. The main processing technologies for ball screws are turning + grinding and hard milling. The turning + grinding process uses soft turning, quenching, hard turning, and grinding to process the thread raceway. The hard milling thread process uses a dedicated precision CNC milling machine CBN tool to mill the thread raceway on the hardened light bar. Both processes can improve processing efficiency and accuracy.

[0025] Working principle: A driving assembly is provided inside the feed box 61 to facilitate the transmission of power to the screw rod 63 so that the slide box 64 on its surface can move horizontally. The length of the screw rod 63 and the two polished rods 62 is equal to the length of the processing table 2, which is suitable for the production of roller screws of different lengths. The setting of cylinder 1 66 and cylinder 2 68 can adjust the distance between the cutter body 610 and the surface of the roller screw according to different production requirements. The cutter body 610 and the mounting seat 69 are detachable, which is convenient for replacing different cutter bodies 610 and increasing the convenience of operation. The slide box 64 is L-shaped, which provides The stability of the slide box 64 when it moves on the processing table 2 is improved. By setting the adjustment mechanism 6, the accuracy of the cutter body 610 and the roller screw in the production process can be ensured, thereby improving production efficiency and product quality. A control panel is also provided on the mold bed body 1. The setting of the control panel is convenient for controlling the working status of the feed box 61, the screw rod 63, the cylinder 1 66 and the cylinder 2 68, thereby improving production efficiency. The roller screw is placed on the processing table 2 on the mold bed body 1, and the roller screw is processed by the cutter body 610. During processing, the roller screw is clamped and fixed by the chuck 5, and then the headstock box 3 can drive the roller screw to move. The speed of the roller screw is adjusted by the headstock 3 according to the actual needs. After that, the staff can fix the cutter body 610 in the mounting seat 69 by the cooperation of the bolts and nuts. Then, the staff controls the cylinder 1 66 to start. The telescopic end of the cylinder 1 66 drives the movable frame 67 to move in the support frame 65, so that the movable frame 67 is located above the roller screw. The setting of the cylinder 2 68 is convenient for controlling the mounting seat 69 and the cutter body 610 to move in the direction of the roller screw, so that the cutter body 610 contacts the surface of the roller screw. Under the rotation of the roller screw, according to the production needs of the roller screw, The cutter body 610 is moved toward the inside of the roller screw so that the slot of the roller screw can be adjusted. At the same time, the setting of the feed box 61 drives the screw rod 63 to rotate. The outer surface thread of the screw rod 63 drives the slide box 64 screwed thereto to move horizontally, and it can be cyclically advanced from left to right. At this time, the slide box 64 is set with the light rod 62, which increases the stability of the slide box 64 when it moves and improves the accuracy during production. The setting of the positioning rod 611 makes it easy to fasten the slide box 64 to the screw rod 63 when the device is not in use, so that the subsequent staff can take out the workpiece, thereby improving production automation and reducing manual labor intensity.

[0026] The second end of the base 711 is connected to the connecting rod 77 and is slidably matched with the base 71. The lower end of the base 71 is detachably connected to the upper end of the processing table 2, which is convenient for quick disassembly or installation. Through the cooperation of the second side plate 711 and the connecting rod 77, the accurate positioning of the roller screw can be ensured during the production process, thereby improving production efficiency and product quality. In addition, one side of the spring 710 is fixedly connected to one side of the positioning plate 79, and the other side of the spring 710 is fixedly connected to one side of the inner wall of the movable groove 76, ensuring that the roller screw is accurately fixed in the position during operation. The bolt connection between the base 71 and the processing table 2 is convenient for the staff to adjust the position of the positioning mechanism 7 according to actual needs. The material of structure 7 is made of high-strength steel to ensure its durability and stability in long-term use. While ensuring the production accuracy of the roller screw, it also improves the production efficiency and product quality. The inner wall of side plate 1 72 is provided with an arc clamping plate 73, and the inner side of the arc clamping plate 73 is provided with a rubber pad 74. The top front end of the base 71 is provided with a driving seat 75, and the inner wall of the driving seat 75 is provided with a movable groove 76. The inner wall of the movable groove 76 is provided with a connecting rod 77 for sliding. The end of the connecting rod 77 away from the side plate 2 711 is provided with an operating handle 78. The middle part of the outer wall of the connecting rod 77 is provided with a positioning plate 79, and the inner side wall of the positioning plate 79 is provided with a spring 710. The setting of the spring 710 makes the side plate 2 711 and the side plate 1 72 close to each other abut. The arrangement can ensure that the roller screw has good stability and accuracy during operation, thereby improving the production efficiency and quality of the roller screw. The base 71 can be installed on the processing table 2 by bolts. By acting on the operating handle 78, the staff pulls the connecting rod 77 to make the connecting rod 77 slide on the inner wall of the driving seat 75. At this time, the positioning plate 79 can slide in the movable groove 76 to stretch the spring 710, and the connecting rod 77 can drive the side plate 711 to move outward. The setting of the operating handle 78 can operate the connecting rod 77 so that the side plate 711 can move outward stably together, which can facilitate the placement of the roller screw in the arc clamping plate 73, improve the effect of operating the side plate 711, and cooperate with the tailstock 8 to stabilize the roller screw. The second side plate 711 is fixed, and the distance between the arc clamping plate 73 on the moving side plate 711 and the arc clamping plate 73 on the side plate 1 is increased, so that the roller screw can be placed between the two arc clamping plates 73, and a roller screw can be placed between the two arc clamping plates 73, so that the roller screw can be installed in the processing table 2. The inner side of the arc clamping plate 73 is bonded with a rubber pad 74, and the rubber pad 74 has a certain elasticity, so that the rubber pad 74 can protect the outer surface of the roller screw and facilitate the placement of the roller screw in the two arc clamping plates 73. Afterwards, the staff releases the operating handle 78, which can reset the side plate 711 under the elastic action of the spring 710, so that the two arc clamping plates 73 clamp the roller screw, so that the roller screw is stably located in the arc clamping plate 73.Therefore, the mold bed body 1 can perform positioning processing on the roller screw, which has a simple structure and is easy to operate, and can improve the production efficiency of the roller screw.
