Description

Technical Field

[0001] The present invention relates to the technical field of grinding of hollow gear shafts, and particularly to a processing device for grinding the inner hole surface of a hollow gear shaft. Background Art

[0002] The processing device for a hollow gear shaft is a device or system specifically designed for grinding or processing the inner hole surface and the outer cylindrical surface of a hollow gear shaft. The processing device includes a grinding machine, which is the basic equipment for processing the hollow gear shaft and provides the necessary rotational and feeding motions. The spindle end of the grinding machine is usually used to install a fixture to fix and support the hollow gear shaft to be processed. One end of the hollow gear shaft is inserted into the inner hole of the fixture, and its inner hole is abutted and positioned against the conical outer cylindrical surface of the floating center. The gear-shaped surface on the outer circle of the other end is abutted and positioned against the outer cylindrical surface of the needle roller. Then, the compression nut is rotated to push the spring chuck to contract inward, so that the outer cylindrical surface of the needle roller presses against the gear-shaped surface of the hollow gear shaft. After starting the grinding machine motor, the hollow gear shaft rotates with the grinding machine spindle and the fixture and grinds the machining position of its inner hole surface.

[0003] When the hollow gear shaft is clamped on the grinding machine by a chuck, a large amount of debris will be generated during the grinding of the inner hole surface of the hollow gear shaft. The debris will fall on the grinding machine, and the accumulation of debris will affect the use of the grinding machine. At the same time, debris will also accumulate in the inner hole surface of the hollow gear shaft, affecting the grinding of the inner hole surface. Summary of the Invention

Specific embodiments

[0021] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0022] Refer to Figures 1-6 , a processing device for grinding the inner hole surface of a hollow gear shaft, including a grinder main body 1 and a screw 204. A lathe chuck 2 and a dust collection assembly 3 are arranged on the grinder main body 1. The hollow gear shaft that needs to be subjected to inner hole surface grinding is clamped on the lathe chuck 2.

[0023] An installation hole 201 is opened inside the lathe chuck 2. A circular plate 203 is installed on one side of the lathe chuck 2. A motor base 205 is installed on the side wall of the circular plate 203 through a screw 204. A motor 206 is installed on the motor base 205. A fan 207 is installed on the output shaft of the motor 206. The fan 207 is arranged inside the installation hole 201. After the inner hole surface of the hollow gear shaft is ground, the fan 207 is used to clean the debris. The motor 206 drives the fan 207 to rotate inside the installation hole 201, generating strong wind to efficiently clean the inner hole surface of the ground hollow gear shaft, preventing debris residue from affecting the quality and subsequent use of the gear shaft.

[0024] The dust collection assembly 3 includes a mounting plate 301 which is mounted on the grinder main body 1. On the top surface of the mounting plate 301, a bottom plate 303 is mounted. On the top surface of the bottom plate 303, a U-shaped plate 304 and a baffle 305 are provided. A magnet 6 is arranged between the U-shaped plate 304 and the baffle 305. The third threaded rod 7 and the threaded sleeve 8 firmly connect the U-shaped plate 304 and the baffle 305, preventing the U-shaped plate 304 and the baffle 305 from shaking or misaligning during the processing, ensuring the adsorption effect of the magnet 6 and the stability of the dust collection assembly.

[0025] The magnet 6 is arranged at the bottom end of the lathe chuck 2. The debris generated during the internal hole surface grinding of the hollow gear shaft falls on the magnet 6. The hollow gear shaft is made of magnetic materials such as steel. The debris generated by the grinding of the hollow gear shaft can be adsorbed by the magnet 6, improving the production efficiency and the safety of the working environment. The magnet 6 strongly adsorbs the ferromagnetic debris generated by the grinding of the hollow gear shaft, preventing the debris from splashing everywhere, avoiding the wear of other parts of the processing device by the debris, and also reducing the risk of the operator being scratched by the debris, improving the safety of the working environment.

[0026] A bracket 101 is mounted on the grinder main body 1. Both the lathe chuck 2 and the mounting plate 301 are mounted on the bracket 101. The bracket 101 provides a firm support for the lathe chuck 2 and the mounting plate 301, ensuring that the entire processing device remains stable during operation, reducing vibration, and being beneficial to improving the grinding accuracy of the internal hole surface of the hollow gear shaft. A threaded groove 202 is opened on the side wall of the lathe chuck 2. A round plate 203 is in threaded fit inside the threaded groove 202. The threaded groove 202 of the lathe chuck 2 and the round plate 203 are in threaded fit. During installation, only the round plate 203 needs to be screwed into the threaded groove 202, and the disassembly is also very convenient, facilitating the maintenance or replacement of components such as the round plate 203 and the motor base 205 and the motor 206 mounted on it.

[0027] Ventilation openings 208 are opened on the round plate 203. Through holes are opened on the round plate 203. The output shaft of the motor 206 extends outside the through hole of the round plate 203. The ventilation openings 208 on the round plate 203 allow air to circulate, preventing a closed space from being formed in the mounting hole 201 when the fan 207 works, being beneficial to heat dissipation, and at the same time enabling the debris cleared out to be better discharged. Two side plates 302 are mounted at one end of the mounting plate 301. The two side plates 302 are mounted on the bracket 101 by bolts. The side plates 302 of the mounting plate 301 are mounted on the bracket 101 by bolts. The installation process is simple, facilitating the positioning and fixing of the mounting plate 301, and also facilitating the overall disassembly and maintenance of the dust collection assembly.

[0028] Two orifice plates 307 are formed in the mounting plate 301. A first threaded rod 308 is installed inside each of the two orifice plates 307. Two first cylinders 306 are installed on the bottom surface of the bottom plate 303. The first cylinders 306 are sleeved on the first threaded rods 308. One end of each first threaded rod 308 is threadedly engaged with a nut 309. The nut 309 is arranged outside the mounting plate 301. The cooperation of the first threaded rod 308 with the first cylinder 306 and the nut 309 facilitates the disassembly of the bottom plate 303 on the mounting plate 301.

[0029] Threaded cylinders 5 are installed on the opposite side walls of the U-shaped plate 304. A second threaded rod 501 is threadedly engaged inside the threaded cylinder 5. The end of the second threaded rod 501 is threadedly engaged with a threaded ring 502. The threaded ring 502 is arranged outside the U-shaped plate 304. Removing the threaded ring 502 facilitates the setting of a baffle 305 between the two side walls of the U-shaped plate 304. A second cylinder 4 is installed on the bottom surface of the baffle 305. The second cylinder 4 is sleeved on the threaded cylinder 5.

[0030] Through holes are formed in both the U-shaped plate 304 and the baffle 305. A third threaded rod 7 is passed through the inside of the through holes. Threaded sleeves 8 are threadedly engaged at both ends of the third threaded rod 7. Removing the third threaded rod 7 and the threaded sleeves 8 facilitates the disassembly of one end of the baffle 305 from the U-shaped plate 304, enabling the baffle 305 to be flipped through the second threaded rod 501 and the threaded ring 502, ensuring the disassembly and installation of the magnet 6.

[0031] When using the processing device to grind the inner hole surface of the hollow gear shaft, the hollow gear shaft is clamped on the lathe chuck 2 of the support 101 on the lathe main body 1. The lathe chuck 2 is used for limiting and fixing the hollow gear shaft during processing. Operate the lathe main body 1 so that the components on the lathe main body 1 can grind the inner hole surface of the hollow gear shaft. The chips generated during the grinding process fall onto the magnet 6 of the dust collection assembly 3. The magnet 6 adsorbs the chips. After the inner hole surface of the hollow gear shaft is ground, start the motor 206 so that the fan 207 blows air in the mounting hole 201, enabling the strong wind generated by the fan 207 to clean the chips ground in the mounting hole 201 and the inner hole surface.
