Description

Technical Field

[0001] The utility model relates to the technical field of gear grinding machines, in particular to a gear grinding machine for gear processing. Background Art

[0002] A gear grinding machine is a gear processing machine that uses a grinding wheel as a grinding tool to process cylindrical gears or certain gears (helical gears, bevel gears, etc.) and the tooth surface of the tool. The gear grinding machine is mainly used to eliminate deformation after heat treatment and improve gear accuracy.

[0003] The gear grinding machine in the prior art will generate a large amount of debris during the gear grinding process. In order to reduce the pollution of the debris to the environment and reduce the harm to the health of the processing personnel, a dust suction mechanism is installed at the processing site. When in use, by starting the vacuum cleaner, the debris generated by the grinding is transported to the collection box through the cooperation of the dust suction pipe and the conveying pipe, which is convenient for subsequent centralized cleaning. At the same time, the debris and dust that are not sucked by the dust suction mechanism will fall from the filter to the collection box below, which has a good effect in collecting debris and dust, thereby improving the cleaning efficiency, reducing the pollution to the environment, and reducing the harm to the health of the processing personnel.

[0004] However, in actual use, some debris and dust will adhere to the filter, causing the debris to accumulate and clump. After long-term use, the filter will be blocked, making the filter unable to filter, and workers will need to clean it manually, which increases the labor intensity of the workers and increases the labor cost. Utility Model Content

[0005] The purpose of the utility model is to provide a gear grinding machine for gear processing to solve the problems raised in the above background technology.

[0008] Preferably, a rubber block is fixedly connected to the bottom end of the dust suction mechanism, the rubber block fits with the collection box, and the collection box is connected with the guide groove.

[0009] Preferably, the connecting block matches the cam, the bottom end of the connecting block fits with the outside of the cam, and the connecting block is slidably connected to the inside of the guide groove.

[0010] Preferably, the limiting grooves on the upper and lower sides are symmetrically distributed, and the outer portion of the clamping block is slidably connected to the inner portion of the limiting groove.

[0011] Preferably, one end of the spring is fixedly connected to the inner wall of the limiting groove, and the other end of the spring is fixedly connected to the left side of the clamping block.

[0012] Preferably, the outer right side of the clamping block is engaged with the inner part of the clamping slot, and the front end of the pull rod is fixedly connected with a handle.

[0013] Compared with the prior art, the beneficial effect of the gear grinding machine for gear processing proposed by the utility model is: by using a cam to oscillate the filter, the debris and dust on the filter will be shaken off and then fall into the inside of the collection box through the guide groove, so that the debris and dust will not adhere to the filter, and workers do not need to clean it manually, thereby reducing the labor workload of workers and reducing labor costs.

The front and rear sides of the filter screen 2 are fixedly connected with connecting blocks 3, so that the filter screen 2 can move when the connecting block 3 moves. The connecting block 3 is slidably connected to the inside of the guide groove 4, and the guide groove 4 limits the internal connecting block 3, so that the connecting block 3 can slide up and down smoothly. The internal rotation of the body 1 is connected with four cams 6, and the body 1 limits the internal cams 6, so that the cams 6 will not deviate when rotating. The connecting block 3 matches the cam 6, and the bottom end of the connecting block 3 fits with the outside of the cam 6, so that each cam 6 can drive the connecting block 3 to slide up and down.

[0025] When it is necessary to clean the debris and dust on the surface of the filter 2, the cam 6 is rotated so that the cam 6 can push the connecting block 3 to move up and down. The four cams 6 are designed opposite to each other, so that the four connecting blocks 3 can move up and down in sequence, and then drive the four corners of the filter 2 to move up and down respectively, so that the filter 2 can shake the debris and dust, so that the debris and dust will not adhere to the surface of the filter 2, so that workers do not need to manually clean the debris and dust on the surface of the filter 2, thereby reducing the labor intensity of workers and reducing labor costs.
