Description

Technical Field

[0001] The utility model relates to the technical field of gear chamfering, and more specifically, to a gear chamfering machine. Background Art

[0002] In the process of producing and preparing gears, according to the different usage requirements of the gears produced, the prepared gears need to be adaptively chamfered and polished, and the chamfering process needs to be completed by a chamfering machine; as an indispensable process in gear production, the chamfering machine has been widely used in this process with the advancement and development of technology.

[0003] After searching, for example, a Chinese patent application with publication number CN205218226U discloses a gear chamfering machine, in which the camshaft to be chamfered is mounted on a workpiece mounting seat, and then an electric grinding head is used to chamfer the gear on the camshaft. After one chamfer is completed, the stepper motor is moved to drive the turntable to rotate, and the rotating turntable drives the camshaft to rotate to perform the next chamfering work; the electric grinding head swings left and right through the operation of the rocker cylinder and the rocker arm. This technology has the advantages of simple structure and easy operation. It can be used to quickly chamfer gears, not only with fast processing speed, but also with good processing quality and low cost. The chamfering machine is easy to maintain, which reduces maintenance costs.

[0004] However, when the above solution is used, it can only chamfer and grind gears with a uniform diameter. If you want to chamfer gears of other diameters, you can only replace the equipment, which is less practical. In addition, the above solution uses a rocker cylinder to realize the rocking of the electric grinding head, and can only chamfer and grind the upper surface of the gear. When grinding the lower surface, the gear needs to be disassembled and installed in reverse, which is more troublesome to operate. Utility Model Content

[0026] like Figure 1 and 2 As shown, the utility model provides a gear chamfering machine, including a workbench 1: a grinder 8 is movably provided at the upper end of the workbench 1, a grinding head 9 is fixedly provided at the output end of the grinder 8, a stepper motor 4 is fixedly provided at the lower end of the workbench 1 through a flange, the output end of the stepper motor 4 passes through the inner side of the workbench 1, a rotating shaft 5 is fixedly provided at the output end of the stepper motor 4, a gear fixing plate 6 is fixedly provided at the upper end of the rotating shaft 5, and a controller 7 is fixedly provided at the upper end of the workbench 1.

[0027] In order to be able to chamfer and grind gears of different diameters, a movable adjustment device 2 capable of driving the grinder 8 to move is provided on the upper end of the workbench 1, and is used to adjust the position of the grinder 8 according to the gear diameter;

[0028] like Figure 3 As shown, the mobile adjustment device 2 includes a first cylinder 21, the first cylinder 21 is fixedly connected to the upper end of the workbench 1 through a bracket, a moving block 22 is fixedly provided at the output end of the first cylinder 21, and sliders 25 are fixedly provided on both sides of the moving block 22, and two limit plates 23 are fixedly provided at the upper end of the workbench 1. A limit groove 24 is provided on the side where the two limit plates 23 are close to each other, and the two sliders 25 are respectively located on the inner sides of the limit grooves 24. A second cylinder 26 is fixedly provided at the upper end of the moving block 22, and a fixing frame 27 is fixedly provided at the upper end of the second cylinder 26. A rotating motor 10 is fixedly provided on one side of the fixing frame 27 through a flange, and the output of the rotating motor 10 The output end passes through one side of the fixed frame 27, and the operation of the first cylinder 21 can drive the moving block 22 to move. In order to ensure smooth movement, the slider 25 and the limiting groove 24 on one side of the limiting plate 23 are used for sliding limitation, so that the lateral adjustment of the fixed frame 27 can be achieved, and gears with different diameters can be chamfered and polished. When it is necessary to polish the back side of the gear, the first cylinder 21 is contracted and then coordinated with the contraction of the second cylinder 26. After the contraction of the second cylinder 26 is completed, the output end of the first cylinder 21 is reset, so that the grinding end 9 contacts the back side of the gear, so that the back side of the gear can be chamfered and polished.

[0029] Furthermore, in order to be able to chamfer and grind both sides of the gear, a swing grinding device 3 capable of driving the grinder 8 to swing is provided on the upper end of the movable adjustment device 2, and is used to drive the grinder 8 to swing in a fan-shaped trajectory;

[0030] like Figure 4As shown, the swing grinding device 3 includes a grinder fixing frame 31, which is fixedly arranged on the outer surface of the grinder 8. The two sides of the grinder fixing frame 31 are hinged to the upper end of the fixing frame 27 through hinge blocks. Two connecting blocks 33 are fixed on one side of the fixing frame 27. The two connecting blocks 33 are close to each other on one side and a slide groove 34 is respectively opened. The lower end of one side of the grinder fixing frame 31 is hinged to a rocking rod 32 through a hinge seat. The lower end of the rocking rod 32 is penetrated by a slide rod 35. The outer surface of the slide rod 35 is hinged to two transmission rods 36. The two transmission rods 36 are respectively located on both sides of the rocking rod 32. The two ends of the connecting block 33 are respectively inserted into the inner side of the slide groove 34.

During the reciprocating movement, the slide bar 35 is limited by the slide groove 34. The slide bar 35 and the rocking rod 32 drive the grinder fixed frame 31 to swing, and its swing trajectory is fan-shaped. When the grinding end 9 is adjusted to any side of the gear, the chamfering grinding effect can be achieved.

[0031] The working principle is as follows: when the present invention is in use, the gear is fixed on the gear fixing plate 6, and the position of the grinder 8 and the grinding end head 9 is adjusted by the movable adjustment device 2 according to the gear diameter. After the adjustment is completed, the grinder 8 is started and the swinging grinding device 3 swings the grinder 8 and the grinding end head 9, and then the stepping motor 4 drives the rotating shaft 5 and the gear fixing plate 6 to rotate slowly, so as to achieve the effect of gear chamfering and grinding. When one side of the gear is polished, the movable adjustment device 2 is used to move the grinding end head 9 to the lower end of the gear, so as to achieve the effect of chamfering and grinding the back side of the gear, which reduces the trouble of disassembling and turning the gear over as a whole, and can achieve chamfering and grinding of gears of different diameters, thereby improving the practicality and convenience of the present invention.

[0032] In addition, it is worth noting that the control processes of electronic devices such as the first cylinder 21, the second cylinder 26, the stepper motor 4, the rotating motor 10 and the grinder 8 in the present invention are all implemented by the controller 7.
