DETAILED DESCRIPTION OF THE EMBODIMENTS

[0018] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0019] Please refer to Figure 1 - Figure 2 , an embodiment of the present utility model provides a numerical control turning, milling and knurling compound machine, including: a frame 1 and a spindle mechanism installed on the frame 1.

[0020] Among them, as Figure 1 - Figure 2 shown, a support table 2 is installed on the top of the frame 1, a first slide rail 5 is fixedly connected to the support table 2, a second slide rail 6 is slidably installed on the first slide rail 5, the spindle mechanism includes a first servo motor 3, the first servo motor 3 is installed on the top of the frame 1, a chuck 4 is fixedly connected to the rotating shaft of the first servo motor 3, and a movable plate 7 is slidably installed on the second slide rail 6.

[0021] During use, the workpiece is clamped by the chuck 4 in the spindle mechanism, and the workpiece is driven to rotate by the first servo motor 3. The movable plate 7 can move on the second slide rail 6 through the second servo motor 12, which is convenient for controlling the movement of the knurling roller 9 to press against the surface of the workpiece.

[0022] In this embodiment, as Figure 1 - Figure 4 shown, two fixing plates 8 are symmetrically installed on the top of the movable plate 7. A threaded rod 18 is rotatably installed on the adjacent side of the two fixing plates 8. Two internal threaded cylinders 14 are symmetrically threadedly connected to the threaded rod 18. The adjacent ends of the two internal threaded cylinders 14 are rotatably installed with snap rings 16 through bearings. Two knurling rollers 9 are symmetrically arranged on the outer wall of the threaded rod 18. Semi-circular plates 17 are provided at both ends of each knurling roller 9. The outer diameter of the semi-circular plate 17 is smaller than the inner diameter of the snap ring 16. When the planes of the two knurling rollers 9 are spliced together, the two semi-circular plates 17 form a ring.

[0023] When installing the knurling roller, the two split knurling rollers 9 are buckled on the outer wall of the threaded rod 18 to form a complete knurling pattern. At this time, the two internal threaded cylinders 14 are synchronously moved and closed along the threaded rod 18 towards both ends of the knurling roller 9, and the semi-circular plates 17 are made to enter the snap rings 16 to ensure that the snap rings 16 squeeze the two ends of the knurling roller 9 to achieve a stable effect. The length of the threaded rod 18 is not less than 15 cm, and different knurling rollers 9 with a length greater than 15 cm can be installed on the threaded rod 18.

[0024] Furthermore, referring to Figure 2, a second servo motor 12 is installed on one side of the second slide rail 6. The rotating shaft of the second servo motor 12 is fixedly connected to a lead screw 13. The lead screw 13 is located inside the first slide rail 5. The lead screw 13 penetrates through the movable plate 7. The movement of the printing roller body 9 is achieved by starting the second servo motor 12 to drive the rotation of the lead screw 13, so that the movable plate 7 can move along the first slide rail 5 under the rotation of the lead screw 13, thereby completing the movement of the printing roller body 9.

[0025] As Figure 1 shown, a movable bracket 10 is slidably installed on the first slide rail 5. A collet 11 is installed on the movable bracket 10. The movable bracket 10 can move on the first slide rail 5, and the collet 11 can clamp the end of the columnar workpiece.

[0026] Specifically, four slots 19 are symmetrically arranged on the plane of one printing roller body 9, and four insertion blocks 15 are symmetrically arranged on the plane of the other printing roller body 9. When the two planes of the printing roller body 9 are spliced together, the insertion blocks 15 can be inserted into the slots 19 to avoid misalignment of the roller body.

[0027] Summarize and sort out the working steps of this solution according to the above technical solution: When the present utility model is used, the workpiece is clamped by the chuck 4 in the main shaft mechanism, and the first servo motor 3 is used to drive the workpiece to rotate. The movable plate 7 can move on the second slide rail 6 through the second servo motor 12, so as to control the movement of the printing roller body 9 to be pressed against the surface of the workpiece.

[0028] Among them, when installing the printing roller, two half printing roller bodies 9 are buckled on the outer wall of the threaded rod 18 to form a complete knurling pattern. At this time, the two internal thread cylinders 14 are synchronously moved and approached along the threaded rod 18 towards both ends of the printing roller body 9, and the semi-circular plate 17 enters the snap ring 16, ensuring that the snap ring 16 presses the two ends of the printing roller body 9 to achieve a stable effect, enabling the printing roller in the turning and milling knurling compound machine to be quickly disassembled and assembled, and adapting printing rollers of various lengths and sizes to be installed on the threaded rod 18 without disassembling the printing roller bracket, meeting the processing requirements of different workpieces.

[0029] Parts not involved in the present utility model are the same as the prior art or can be implemented by the prior art. Although the embodiments of the present utility model have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirits of the present utility model. The scope of the present utility model is defined by the appended claims and their equivalents.
