Description

Technical Field

[0001] The invention relates to the technical field of gear processing, and in particular to an inner ring smoothness processing device and a processing method for gear processing. Background Art

[0002] Gears are widely used in mechanical transmission, so they come in many sizes and types. After the gears are manufactured, the inner rings often need to be smoothed to ensure their accuracy and aesthetics. For smaller gears, the inner rings can often be polished manually because the workload is not large. However, for some larger gears, if they are polished manually, the workload will be very large and the speed will be slow, which will affect the delivery process of the gears. Therefore, a gear processing inner ring smoothness processing device is needed. However, the existing gear processing inner ring smoothness processing device has the following problems:

[0003] 1. Since there are many types of gears, the inner ring sizes often vary. The existing inner ring smoothness processing devices for gear processing are often designed for gears with a certain inner ring size and can only perform grinding processing on gears with a fixed inner ring size, which greatly reduces its applicability;

[0004] 2. When the existing inner ring smoothness processing device for gear processing is used to grind the inner ring of the gear, it is usually ground in one direction, which leads to incomplete grinding. The inner ring of the gear is more likely to have grinding marks, affecting the smoothness.

[0005] In view of the above problems, it is urgent to carry out innovative design based on the existing inner ring smoothness processing device for gear processing. Summary of the invention

[0006] The purpose of the present invention is to provide an inner ring smoothness processing device and a processing method for gear processing, so as to solve the problem proposed in the above background technology that the existing inner ring smoothness processing device for gear processing can often only grind an inner ring of one size, and can only grind in one direction during grinding, which easily causes grinding marks on the inner ring of the gear and affects the smoothness.

[0007] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: an inner ring smoothness processing device for gear processing, comprising an operating table, a first electric cylinder, a clamping mechanism, a second electric cylinder and a motor, a through hole is opened in the middle position of the top of the operating table, and the first electric cylinder is fixed on both sides of the top of the operating table, and the output end of the first electric cylinder is connected to the clamping mechanism, a support frame is fixed to the operating table on the side of the first electric cylinder away from the clamping mechanism, and the bottom of the support frame is provided with a second electric cylinder, and the output end of the second electric cylinder is installed with a mounting seat, and a motor is provided on the side of the mounting seat, a first device bin is installed at the bottom of the mounting seat, and a sleeve is provided inside the first device bin, and the sleeve passes through the first device bin, and a first screw rod is installed inside the sleeve, the first screw rod passes through the first device bin, and the second device bin is fixed on the outer side of the first screw rod away from the first device bin. The cam is an angularly-shaped member which is fixed to the side of the second gear box and has a first end which is adapted to move relative to the first gear box.

[0008] Preferably, the sleeve is fixedly connected to the output end of the motor, and the sleeve and the first device compartment form a relatively rotating structure.

[0009] Preferably, the first screw rod and the sleeve form a relative sliding structure, and the first screw rod and the first device compartment are threadedly connected.

[0010] Preferably, the mounting rod is sleeved on the outside of the fixed shaft, and the mounting rod and the fixed shaft form a relatively rotating structure.

[0011] Preferably, a central axis of the second gear is parallel to a central axis of the first gear, and the second gear is meshingly connected to the first gear.

[0012] Preferably, the second bevel gear and the first bevel gear are perpendicular to each other, and the second bevel gear and the first bevel gear are meshingly connected.

[0013] Preferably, the side cross-section of the movable rod is in a "U" shape, the movable rod is threadedly connected to the second screw rod, and the movable rod and the second device compartment form a relative sliding structure.

[0014] Compared with the prior art, the invention has the following beneficial effects: the inner ring smoothness processing device for gear processing can process the smoothness of gears with inner rings of different sizes, and can grind the gears in two directions, so that the grinding can be more comprehensive and sufficient;

[0015] 1. Through the threaded connection between the movable rod and the second screw rod, the sliding connection between the movable rod and the second device bin, and the meshing connection between the second bevel gear and the first bevel gear, the operator can adjust the distance between the rubber sheet and the first screw rod by rotating the rotating rod, so that the sandpaper can be closely attached to the inner ring of gears of different sizes to process their glossiness, which greatly increases the applicability of the device;

[0016] 2. Through the sliding connection between the sleeve and the first screw rod, and the threaded connection between the first screw rod and the first device bin, the motor can drive the sleeve to rotate while driving the first screw rod to move up and down continuously, so that the sandpaper can continuously rotate and grind the inner ring of the gear while continuously moving up and down to further grind the inner ring of the gear, which can make the grinding more comprehensive and sufficient.
