Description

Technical Field

[0001] This utility model belongs to the field of positioning column processing technology, specifically referring to a positioning column processing device. Background Technology

[0002] In the field of mechanical manufacturing, positioning pins are important positioning components, and their machining quality and efficiency directly affect the accuracy of mechanical assembly and the production cycle. Currently, traditional positioning pin machining devices widely use three-jaw chucks to fix the workpiece. In actual machining, the three-jaw chuck can only fix one end of the positioning pin. When the other end of the positioning pin needs to be cut, it must be removed from the chuck, readjusted, and fixed in position. This process is not only cumbersome and time-consuming, but also prone to positioning errors due to repeated clamping, reducing machining accuracy.

[0003] Since the positioning pins are usually cylindrical and have different shapes at both ends, traditional processing equipment cannot cut both ends at the same time and can only use segmented processing, resulting in low processing efficiency and difficulty in meeting the ever-increasing production demand. Utility Model Content

[0004] In view of the above situation and to overcome the defects of the prior art, this utility model provides a positioning post processing device, which effectively solves the problem that the two ends of the positioning post cannot be cut and processed at the same time.

[0005] To achieve the above functions, the technical solution adopted by this utility model is as follows: a positioning column processing device, including a base and an annular support frame, the support frame is fixed on the base, an annular rotating frame is rotatably provided inside the support frame, an adjustable annular fixed frame is provided inside the rotating frame, a cylinder is symmetrically provided on the inner wall of the fixed frame, a clamping plate is fixed at the movable end of the cylinder for clamping the positioning column, and cutting structures are provided on both sides of the support frame;

[0006] The outer wall of the rotating frame is provided with an annular rack, and the inner wall of the support frame is provided with mounting frames at equal intervals. Gears that mesh with the annular rack are rotatably connected to the mounting frames, and a motor connected to the gear is mounted on one of the mounting frames.

[0007] Preferably, the inner wall of the support frame is equipped with limit frames that rotate relative to the rotating frame at equal intervals.

[0008] Preferably, the cutting structure includes an external frame and a threaded rod. The external frame is fixed to the outer wall of the support frame, and a second motor is mounted on the external frame. One end of the threaded rod is connected to the second motor, and the other end is horizontally rotatably mounted on the outer wall of the limiting frame. A movable block that is pressed against the inner wall of the support frame is threaded onto the threaded rod. A second cylinder perpendicular to the direction of the threaded rod is fixed on the movable block. A mounting block is fixed to the movable end of the second cylinder, and a cutter is fixed on the mounting block by screws. The cutting edge shapes and functions of the two cutters are different.

[0009] Preferably, a motor is installed on the inner wall of the rotating frame, and a rotating shaft is fixedly connected to the output end of the motor. The end of the rotating shaft away from the motor is fixedly connected to the fixed frame.

[0010] Preferably, the annular rack and the annular rotating frame are integrally cast, and the module of the rack matches the module of the gear, and the rotation axis of the gear is parallel to the axis of the support frame.

[0011] Preferably, the inner surface of the clamping plate is provided with an anti-slip pad, and the stroke range of the cylinder is adjusted by programming through an external controller to accommodate positioning pins of different diameters.

[0012] The beneficial effects of the above-mentioned structure are as follows: Through the design of the annular support frame, the annular rotating frame and the cutting structure on both sides, the two ends of the positioning column can be cut at the same time. Compared with the traditional processing device that requires multiple clamping and segmented processing, the processing time is greatly shortened and the production efficiency is significantly improved.

[0020] like Figure 1-4 As shown, the positioning column processing device proposed in this utility model includes a base 1 and an annular support frame 2. The support frame 2 is fixed on the base 1. An annular rotating frame 3 is rotatably provided inside the support frame 2. An adjustable annular fixed frame 4 is provided inside the rotating frame 3. Cylinders 5 are symmetrically provided on the inner wall of the fixed frame 4. A clamping plate 6 is fixed to the movable end of the cylinder 5 for clamping the positioning column. The inner surface of the clamping plate 6 is provided with an anti-slip pad. The stroke range of the cylinder 5 is adjusted by programming through an external controller to adapt to positioning columns of different diameters. Cutting structures 7 are provided on both sides of the support frame 2.

[0021] like Figure 1 , 2As shown, the inner wall of the support frame 2 is equipped with limit frames 12 that rotate relative to the rotating frame 3 at equal intervals, limiting the rotation of the rotating frame 3. The outer wall of the rotating frame 3 is provided with an annular rack 8. The inner wall of the support frame 2 is provided with mounting frames 9 at equal intervals. The mounting frames 9 are rotatably connected to gears 10 that mesh with the annular rack 8. One of the mounting frames 9 is equipped with a motor 11 connected to the gear 10. The annular rack 8 and the annular rotating frame 3 are integrally cast, and the module of the rack matches the module of the gear 10. The rotation axis 20 of the gear 10 is parallel to the axis of the support frame 2.

[0022] like Figure 4 As shown, the cutting structure 7 includes an outer frame 13 and a threaded rod 14. The outer frame 13 is fixed on the outer wall of the support frame 2. A second motor 15 is installed on the outer frame 13. One end of the threaded rod 14 is connected to the second motor 15, and the other end is horizontally rotatably mounted on the outer wall of the limit frame 12. A moving block 16 is threadedly connected to the threaded rod 14 and pressed against the inner wall of the support frame 2. A second cylinder 17 perpendicular to the direction of the threaded rod 14 is fixed on the moving block 16. A mounting block 21 is fixed to the movable end of the second cylinder 17. A cutter 18 is fixed on the mounting block 21 by screws. The cutting edge shape and function of the two cutters 18 are different.

[0023] like Figure 2 As shown, a motor 19 is installed on the inner wall of the rotating frame 3. A rotating shaft 20 is fixedly connected to the output end of the motor 19. The end of the rotating shaft 20 away from the motor 19 is fixedly connected to the fixed frame 4. The rotating shaft 20 and the fixed frame 4 are driven by the motor 19 to rotate in the horizontal direction to adjust the angle.

[0024] In practical use, the positioning post is placed in the clamping plate 6, and the cylinder 5 is started to clamp and fix the positioning post in the clamping plate 6. According to the processing requirements of the positioning post, a suitable cutter 18 is selected for installation. The motors 15 in the cutting structures 7 on both sides are started respectively. The motors 15 drive the threaded rod 14 to rotate. Through the threaded transmission, the moving block 16 moves along the threaded rod 14 to adjust the horizontal position of the cutter 18. Then, the cylinder 17 is started. The cylinder 17 drives the mounting block 21 and the cutter 18 to move vertically so that the cutter 18 reaches the predetermined cutting position. The motor 11 is started. The motor 11 drives the gear 10 to rotate.

[0027] After the two ends of the positioning post are machined, first turn off the cutting power system, and then retract the cutters 18 on both sides to their initial positions through cylinder 17 and motor 15. Then, start cylinder 5 to release the clamping plate 6 and remove the machined positioning post from the annular fixing frame 4, completing the entire machining process.
