Device for removing burr from inner pin hole of gear shifting oscillating bar

[0017] In the following, the present invention will be further explained through the embodiments and the accompanying drawings:

[0018] Combine image 3 , Figure 4 As shown, a gear shift lever inner pin hole deburring equipment consists of a base 1, a support column 2, a drive motor 3, an advance and retreat knife drive cylinder 4, a cemented carbide rotary file 5, a sliding support plate 6, and a car swing rod sleeve column 7. Two connecting rods 8, two return springs 9, two support blocks 10, four bearings 11, four mounting shafts 12, two automobile swing rod anti-rotation blocks 13, two limit plates 14, several Hexagonal bolts 15, manual swing rod 16, mounting bracket 17, hoop plate 18, plastic tube 19 and so on. Except for the advance and retreat knife driving cylinder 4, the mounting bracket 17 and the hoop plate 18, the deburring equipment has a symmetrical structure.

[0019] The support column 2 is installed on the base 1, and the top of the support column 2 is provided with an organic head, and the head is composed of a driving motor 3, an advance and retreat knife driving cylinder 4, and a cemented carbide rotary file 5, etc. The drive motor 3 drives the cemented carbide rotary file 5 to rotate, and the forward and retreat drive cylinder 4 drives the cemented carbide rotary file 5 to move up and down. The forward and backward knife drive cylinder 4 is fixed on the side wall of the support column 2 through the mounting bracket 17. The lower end of the piston rod of the forward and backward knife drive cylinder 4 is connected with the hoop plate 18, and the hoop plate 18 is fixedly sleeved on the knife of the cemented carbide rotary file 5. Seat, thereby driving the cemented carbide rotary file 5 to move up and down. The head of a traditional vertical machine tool consists of a drive motor, a manual turntable and a tool. The drive motor drives the tool to rotate, and the manual turntable drives the tool up and down through a rack and pinion mechanism. The head of this machine is replaced by a manual turntable by a cylinder driven by the forward and backward knife. Compared with the manual turntable, the control accuracy and automation are higher.

[0020] A sliding support plate 6 is provided on the base 1, and the width of the middle part of the sliding support plate 6 is smaller than the width of the upper and lower ends to form a neck 6a. The sliding support plate 6 is made of three steel plates with different widths, which are upper, middle, and lower, and are fixedly connected as a whole. An automobile swing rod sleeve column 7 and an automobile swing rod anti-rotation block 13 are fixedly arranged above the sliding support plate 6. The automobile swing rod sleeve column 7 is located directly below the cemented carbide rotary file 5, and there are two automobile swing rod anti-rotation blocks 13, which are located directly behind the automobile swing rod sleeve column 7 and are arranged symmetrically. The diameter of the automobile swing rod sleeve column 7 matches the diameter of the shift shaft mounting hole of the workpiece, and the spacing of the automobile swing rod anti-rotation block 13 matches the width of the ball head of the workpiece.

[0021] A manual swing rod 16 is hinged at the middle position of the front side wall of the sliding pallet 6, and the manual swing rod 16 can swing left and right, as shown by the arrow in the figure. Preferably, the manual swing lever 16 is sheathed with a hollow plastic tube 19. The left and right sides of the sliding support plate 6 are each provided with a connecting rod 8 extending left and right, a return spring 9 is sleeved on the connecting rod 8, and a support block 10 for supporting the connecting rod 8 is provided on the outside of each connecting rod 8. The support block 10 is fixed on the base 1, the inner end of the connecting rod 8 is fixed on the side wall of the sliding bracket 6, the outer end of the connecting rod 8 extends out of the corresponding support block 10, and the outer end of the connecting rod 8 has 端头8a. Two bearings 11 arranged at intervals on the front and rear sides of the sliding support plate 6 are provided for guiding the left and right movement of the sliding support plate 6, a total of four bearings 11 are arranged in a rectangular shape. The bearings 11 are installed and fixed by their respective mounting shafts 12. A limit plate 14 is provided on the left and right sides of the neck 6a of the sliding pallet 6 to limit the left and right movement of the sliding pallet 6, and the front and back of each limit plate 14 The two ends are respectively fixed on the two mounting shafts 12 on the same side. The height of the limit plate 14 shall not be greater than the height of the neck 6a of the sliding support plate 6 to ensure that the limit plate 14 can extend into the neck 6a of the sliding support plate 6.

[0022] Preferably, the base 1 is divided into three layers from bottom to top, and is fastened together by a number of external hexagon bolts 15. The support block 10 is fixed above the second layer and abuts against the side edge of the third layer.
