[0002] As a type of machine tool, thread grinding machines have a wide range of applications. They can be used to process thread gauges, thread rolling rollers, ball screws, ball nuts, worm gears, taps, hobs, thread milling cutters, and other threaded parts. Thread grinding machines have a complex structure and many components, including a grinding wheel chuck for mounting the grinding wheel.

[0003] Existing grinding wheel chucks are insufficient in improving grinding stability and reducing grinding noise. Utility Model Content

[0004] The purpose of this invention is to provide a grinding wheel chuck with shock-absorbing blades for a thread grinding machine, which can effectively improve the stability of grinding wheel rotation, improve grinding stability and grinding effect, and reduce grinding noise. At the same time, each component can be flexibly and conveniently disassembled and assembled.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A grinding wheel chuck with vibration-absorbing blades for a thread grinding machine includes a grinding wheel chuck, a grinding wheel chuck cover plate is sleeved on one end of the grinding wheel chuck, a grinding wheel is clamped between the grinding wheel chuck cover plate and the grinding wheel chuck, the optimal grinding diameter of the grinding wheel is 480 mm, and multiple vibration-absorbing blades are installed on the edges of both the grinding wheel chuck and the grinding wheel chuck cover plate, with portions of the vibration-absorbing blades adhering to the outer surfaces of both sides of the grinding wheel.

[0007] By adopting the above technical solutions, the grinding stability of the grinding wheel can be effectively improved, the polarization amplitude during grinding can be reduced, and the grinding effect can be improved.

[0008] Furthermore, the shock-absorbing blade includes a reinforcing steel plate and a nylon sheath, the nylon sheath being wrapped around the outside of the reinforcing steel plate.

[0009] By adopting the above technical solutions, the overall structural strength and shock absorption performance of the shock-absorbing blades are ensured.

[0010] Furthermore, multiple second connection holes are provided on the outer surfaces of the grinding wheel chuck, the grinding wheel chuck cover plate, and the shock-absorbing blades.

[0011] By adopting the above technical solution, it is easy to install and disassemble the vibration-absorbing blades.

[0012] Furthermore, multiple shock-absorbing blades on the same side are arranged in a circular array and connected end to end.

[0013] By adopting the above technical solution, it can be ensured that the shock-absorbing blades perform stable shock absorption operation.

[0014] Furthermore, a heat sink is installed on one outer surface of the grinding wheel chuck cover plate, and the heat sink, the grinding wheel chuck, and the outer surface of the grinding wheel chuck cover plate are all provided with corresponding first connecting holes.

[0015] By adopting the above technical solution, the heat sink base can be easily installed and disassembled.

[0016] Furthermore, multiple blades are fixedly connected to the outer surface of the heat sink base, and a flow guide is fixedly connected to the outside of the blades. An exhaust channel is provided between the flow guide and the base of the heat sink base.

[0017] By adopting the above technical solution, airflow can be effectively driven to achieve efficient heat dissipation.

[0018] In summary, the beneficial technical effects of this utility model are as follows:

[0019] 1. This utility model allows for the installation of a 500 mm diameter grinding wheel between the grinding wheel chuck and the grinding wheel chuck cover plate when grinding ball screws using a thread grinder. Multiple shock-absorbing blades are then installed at the edges of the grinding wheel chuck and the grinding wheel chuck cover plate, with the blades resting against the outer surfaces of the grinding wheel. This enables effective grinding. When grinding the surface finish of the ball screw, the shock-absorbing blades effectively improve the stability of the grinding wheel, thus enhancing the grinding stability of the ball screw. When the diameter of the grinding wheel is reduced to 480 mm, the shock-absorbing blades are removed, and the surface grinding of the ball screw continues. Since the outermost diameter of the shock-absorbing blades is 460 mm, removing the blades avoids collisions during grinding. Furthermore, because the grinding wheel wears down evenly at the grinding end, the grinding spacing is optimal, resulting in the best possible surface grinding operation for the ball screw.

[0020] 2. This utility model, through the arrangement of the heat sink base, blades, and air guide, allows the heat sink base to be installed simultaneously with the grinding wheel. When the grinding wheel chuck rotates, it effectively drives the heat sink base to rotate. At this time, the blades that rotate with the heat sink base can effectively guide the air and allow the air to be discharged from the exhaust groove of the air guide. The discharged air can effectively blow onto the grinding wheel, thereby enabling heat dissipation during the grinding process, effectively improving grinding stability, and significantly enhancing practicality.

[0024] The method of this utility model will be further described in detail below with reference to the accompanying drawings.

[0025] Reference Figure 1 , Figure 2 A grinding wheel chuck with shock-absorbing blades for a thread grinding machine includes a grinding wheel chuck 1, a grinding wheel chuck cover plate 3 sleeved on one end of the grinding wheel chuck 1, and a grinding wheel 2 clamped between the grinding wheel chuck cover plate 3 and the grinding wheel chuck 1. The optimal grinding diameter of the grinding wheel 2 is 480 mm. Multiple shock-absorbing blades 4 are installed on the edges of both the grinding wheel chuck 1 and the grinding wheel chuck cover plate 3. Partial sections of the shock-absorbing blades 4 are attached to the outer surfaces of both sides of the grinding wheel 2. Each shock-absorbing blade 4 includes a reinforcing steel plate 5 and a nylon sleeve 6, with the nylon sleeve 6 covering the outside of the reinforcing steel plate 5. Multiple corresponding second connecting holes 11 are provided on the outer surfaces of the grinding wheel chuck 1, the grinding wheel chuck cover plate 3, and the shock-absorbing blades 4. Multiple shock-absorbing blades 4 on the same side are arranged in a circular array and connected end to end. This allows for the grinding of ball screws with a diameter of 500 mm using the thread grinding machine. The grinding wheel 2 is installed between the grinding wheel chuck 1 and the grinding wheel chuck cover plate 3. Then, multiple shock-absorbing blades 4 are installed at the edges of the grinding wheel chuck 1 and the grinding wheel chuck cover plate 3, so that the shock-absorbing blades 4 can abut against the outer surfaces of both sides of the grinding wheel 2. At this time, effective grinding operation can be performed. When grinding the surface finish of the ball screw, the shock-absorbing blades 4 can effectively improve the stability of the grinding wheel 2, thereby effectively improving the grinding stability of the ball screw. When the diameter of the grinding wheel 2 is worn down to 480 mm, the shock-absorbing blades 4 are removed, and then the surface grinding operation of the ball screw continues. Since the outermost contour diameter of the shock-absorbing blades 4 is 460 mm, the removal of the shock-absorbing blades 4 can avoid collisions during grinding. Also, since the grinding end of the grinding wheel 2 is worn down evenly, the grinding spacing is optimal, so the surface grinding operation of the ball screw can be performed in the best condition.

[0026] Reference Figure 1 , Figure 2A heat sink 8 is installed on one outer surface of the grinding wheel chuck cover 3. The outer surfaces of the heat sink 8, the grinding wheel chuck 1, and the grinding wheel chuck cover 3 are all provided with corresponding first connecting holes 7. Multiple blades 9 are fixedly connected to the outer surface of the heat sink 8. A guide shroud 10 is fixedly connected to the outside of the blades 9. An exhaust groove is provided between the guide shroud 10 and the base of the heat sink 8. Through the arrangement of the heat sink 8, blades 9, and guide shroud 10, the heat sink 8 can be installed at the same time as the grinding wheel 2. When the grinding wheel chuck 1 rotates, it can effectively drive the heat sink 8 to rotate. At this time, the blades 9 that rotate with the heat sink 8 can effectively guide the air and make the air exit from the exhaust groove of the guide shroud 10. The exhaust air can effectively blow onto the grinding wheel 2, thereby performing heat dissipation during the grinding process, effectively improving grinding stability and practicality.

[0027] Working principle: In use, a 500 mm diameter grinding wheel 2 is installed between the grinding wheel chuck 1 and the grinding wheel chuck cover plate 3. Then, multiple shock-absorbing blades 4 are installed at the edges of the grinding wheel chuck 1 and the grinding wheel chuck cover plate 3, so that the shock-absorbing blades 4 can abut against the outer surfaces of both sides of the grinding wheel 2. At this time, effective grinding operation can be performed. When grinding the surface finish of the ball screw, the shock-absorbing blades 4 can effectively improve the stability of the grinding wheel 2, thereby effectively improving the grinding stability of the ball screw. When the diameter of the grinding wheel 2 is worn down to 480 mm, the shock-absorbing blades 4 are removed, and then the surface grinding operation of the ball screw continues. Because the outermost edge of the shock-absorbing blades 4... With a side profile diameter of 460 mm, removing the shock-absorbing blades 4 can prevent collisions during grinding. Furthermore, since the grinding end of the grinding wheel 2 is evenly worn and the grinding spacing is optimal, the ball screw surface grinding operation can be performed in the best condition. The heat sink 8 can be installed at the same time as the grinding wheel 2. When the grinding wheel chuck 1 rotates, it can effectively drive the heat sink 8 to rotate. At this time, the blades 9 that rotate with the heat sink 8 can effectively guide the air and allow the air to be discharged from the exhaust groove of the guide shroud 10. The discharged air can effectively blow onto the grinding wheel 2, thereby performing heat dissipation during the grinding process and effectively improving grinding stability.
