[0001] The invention relates to the technical field of disc sleeve parts processing, and in particular to a vertical punching and slotting composite processing device for disc sleeve parts. Background Art

[0002] Disc sleeve parts generally refer to rotating parts with relatively small axial dimensions and relatively large radial dimensions. They usually have a center hole and are used to be installed on the shaft to achieve functions such as rotational motion or positioning.

[0003] When processing the axle disc used on tricycles, it is necessary to drill holes in its circumference and open a keyway in the central axle hole. Currently, drilling and opening the keyway are performed separately. After opening the keyway, the workpiece needs to be removed and installed on a punching machine for drilling. Drilling and grooving operations cannot be performed at the same time. Multiple disassembly and assembly of parts result in low processing accuracy, and there are safety hazards when using it. Therefore, we propose a vertical punching and slotting composite processing device for disc sleeve parts to solve the above problems. Summary of the invention

DETAILED DESCRIPTION

[0031] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more explicit definition of the protection scope of the present invention. The directional terms mentioned in the present invention, such as "up", "down", "front", "back", "left", "right", "top", "bottom", etc., are only referenced to the directions of the attached drawings. Therefore, the directional terms used are used to illustrate and understand the present invention, rather than to limit the present invention.

[0032] like Figure 1-7 The vertical punching and slotting composite processing device for disc sleeve parts shown in the figure is mainly used for processing tricycle axle discs, comprising a base frame 1, a column 2 is fixed on the base frame 1, a table 3 with a through hole in the middle is installed on one side of the column 2, a tooling plate 31 for mounting a workpiece is arranged in the middle of the table 3, both sides of the table 3 are fixedly connected to the column 2 through support plates, the stability of the table 3 is enhanced by the side support plates, and at the same time, the waste chips generated during drilling are shielded, a circular hole is opened in the middle of the tooling plate 31, and four first mold holes 311 are arranged on the outside of the circular hole;

[0034] The fixed die seat 7 includes a first fixed seat 71, a second fixed seat 72 and a pressing plate 73, both of which are "concave" shaped structures. By placing the workpiece in the first fixed seat 71, the outer wall of the first fixed seat 71 limits the left and right directions of the workpiece, and the middle of the first fixed seat 71 and the second fixed seat 72 are both provided with positioning convex ribs 711, and the setting of the positioning convex ribs 711 facilitates centering the workpiece. Four second die holes 712 are provided on the outer side of the positioning convex ribs 711, and the second die holes 712 are opposite to the first die holes 311. The first fixing seat 71 is aligned, and a plurality of springs 713 are circumferentially arranged at the edge of the inner bottom surface of the first fixing seat 71. The springs 713 are evenly distributed around the center of the first fixing seat 71. When the plug 64 is lifted up during the slot processing, the tool vibration phenomenon will occur during the contact with the workpiece. The setting of the spring 713 can buffer the workpiece in the tool lifting step, reduce the vibration when the plug 64 contacts the workpiece, thereby improving the processing accuracy and the service life of the plug 64. At the same time, after the workpiece processing is completed, the workpiece can be ejected by the setting of the spring 713, which is convenient for the workpiece to be taken out;

The driving gear 59 and the driven gear 58 are both located in the assembly cavity, and a cover is detachably connected to the bottom of the assembly cavity. The driving motor 54 is installed at the bottom of the cover. The setting of the cover facilitates the assembly of the driving gear 59 and the driven gear 58.

[0040] Secondly, the slot mechanism includes a third servo motor 65 fixed on the column 2 and a drag box 6 installed on the guide rail 4. A third ball screw 66 is fixed on the output shaft of the third servo motor 65. The third ball screw 66 is threadedly connected to the drag box 6.

[0042] Furthermore, a piano cover 67 is directly provided between the drag box 6 and the third servo motor 65. The piano cover 67 covers the guide rail 4. The piano cover 67 protects the upper part of the drag box 6 to reduce the entry of impurities such as dust.

[0043] In this embodiment, the device is used to process the axle disc of a tricycle. At present, in the tricycle industry, the gap between the axle disc of a tricycle and the axle has an error of more than ten threads, and the matching degree is poor. When the device is used, the workpiece is placed in the first fixed seat 71, and the peripheral disc is centered by the positioning convex ridge 711, and then the second fixed seat 72 is placed in the first fixed seat 71, and the pressing plate 73 is covered in the second fixed seat 72 again and connected to the tooling plate 31 by bolts to fix it on the tooling plate 31, and the axle disc is squeezed to fix the axle disc, and the initial position of the mounting seat 53 is adjusted by the first servo motor 51, and the initial position of the towing box 6 is adjusted by the third servo motor 65;

[0044] The driving motor 54 is turned on, and the driving motor 54 drives the driving gear 59 to rotate, and drives all the power rods 55 to rotate through the driven gear 58 meshing therewith, so that the drill bit 57 rotates, and the first servo motor 51 continues to rotate, driving the mounting seat 53 to rise, and at the same time drives the drill bit 57 to rise to perform a drilling operation on the workpiece;

[0045] While the workpiece is being drilled, the third servo motor 65 drives the drag box 6 to descend, and the second servo motor 61 drives the key-insertion power head 63 to move left and right. The third servo motor 65 and the second servo motor 61 drive the plug 64 to reciprocate and process the slot on the workpiece. By drilling and opening keyways on the disc and sleeve parts from the top and bottom directions at the same time, multiple clamping of the disc and sleeve parts is avoided, thereby improving the processing accuracy of the disc and sleeve parts and improving the processing efficiency.
