Description

Technical Field

[0001] This utility model relates to the field of machining technology, and in particular to a gear deburring mechanism. Background Technology

[0002] The complete gear machining process includes multiple steps such as precision turning, gear hobbing, and heat treatment. After the gear hobbing process, a large number of burrs will be left on one end face of the gear. Gear deburring is also an important step in the gear machining process. Its main purpose is to improve the flatness and smoothness of the gear surface and increase the smoothness of gear operation.

[0003] Traditional deburring methods mainly rely on manual operation, such as using sandpaper, files and other tools for manual polishing. This is difficult to meet the needs of modern high-efficiency production, and it is also difficult to guarantee the consistency and quality of deburring. In addition, manual operation has significant safety hazards and increases the risk of workplace accidents. Utility Model Content

[0004] In order to overcome the shortcomings of existing deburring methods that mainly rely on manual operation, are inefficient and pose safety hazards, this utility model provides a gear deburring mechanism.

[0005] The technical solution of this utility model is: a gear deburring mechanism, comprising:

[0010] The first bearing is slidably mounted on the support shaft and located on the upper side of the bearing housing;

[0011] A deburring tool is positioned on the outside of the first bearing;

[0012] The second bearing is slidably mounted on the support shaft and located above the first bearing;

[0013] The top cover is slidably mounted on the support shaft, located above the second bearing; and

[0014] Bolts, threaded connections are made to the top of the support shaft to secure the top cover to the support shaft.

[0015] In one embodiment, it further includes:

[0016] The bearing cover is slidably mounted on the support shaft, located between the first and second bearings.

[0017] In one embodiment, both the lower part of the support base and the upper part of the bearing base are provided with limiting rings, and the spring is located between the upper and lower limiting rings.

[0018] In one embodiment, the spring is a rectangular spring.

[0019] In one embodiment, the end faces of the support and bearing housing have notches that allow them to interlock and provide a certain buffer space.

[0020] In one embodiment, the end face notches of the support and the bearing housing are evenly distributed.

[0021] In one embodiment, the second bearing is a thrust ball bearing.

[0022] In one embodiment, the bolt has an internal hexagonal hole at the top.

[0023] In one embodiment, the first bearing and the deburring tool are connected by an interference fit.

[0024] In one embodiment, the deburring tool is made of cemented carbide.

[0025] The beneficial effects of this utility model are as follows: 1. Through the design of components such as spring, first bearing and deburring tool, this utility model can realize the automatic removal of burrs on the end face of gears, reducing the need for manual intervention. Moreover, due to the buffering function of the spring, the end face of the gear will not be scratched, ensuring product quality. By installing the support shaft on the machine tool, gear hobbing and deburring are integrated together, improving processing efficiency and saving time costs for changing processes.

[0032] The present invention will now be described more fully below with reference to the accompanying drawings, in which presently preferred embodiments of the invention are shown. However, the present invention may be embodied in many different forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided for thoroughness and completeness and to fully convey the scope of the invention to those skilled in the art.

[0033] A gear deburring mechanism, such as Figures 1-4 As shown, the assembly includes a support shaft 1, a support seat 2, a spring 3, a bearing seat 4, a first bearing 5, a deburring tool 6, a second bearing 8, a top cover 9, and bolts 10. The support shaft 1 is slidably equipped with the support seat 2 and the bearing seat 4, which are located above the support seat 2. A spring 3 connects the support seat 2 and the bearing seat 4. The first bearing 5 is located on the upper side of the bearing seat 4, and the deburring tool 6 is located on the outer side of the first bearing 5. The second bearing 8 and the top cover 9 are located on the upper side of the first bearing 5 from bottom to top. Bolts 10 are threadedly connected to the top of the support shaft 1, and bolts 10 secure the first bearing 5, the bearing cover 7, and the second bearing 8 to the support shaft 1.

[0034] In use, the support shaft 1 is fixed on the machine tool to ensure the stability of the entire mechanism. Then, the position is adjusted so that the cutting edge of the deburring tool 6 is flush with the end face of the gear to be processed. After positioning, the gear is temporarily removed, and the deburring mechanism is raised 2-3 mm along the Z direction of the spindle. Then, the gear is loaded into the tooling during gear hobbing. At this time, the lower end face of the gear will press against the deburring tool 6, causing the spring 3 to compress, thereby ensuring close contact between the deburring tool 6 and the gear. During gear hobbing, the deburring tool 6 can effectively remove the burrs generated on the lower end face of the gear.

[0035] like Figure 2 As shown, it also includes a bearing cover 7, an upper bearing cover 7 on the first bearing 5, a bearing cover 7 that is slidably connected to the support shaft 1, and a bearing cover 7 located between the first bearing 5 and the second bearing 8. The bearing cover 7 provides a certain degree of protection for the first bearing 5.

[0036] Both the lower part of the support base 2 and the upper part of the bearing housing 4 are provided with limiting rings. The spring 3 is located between the upper and lower limiting rings. The limiting rings at the lower part of the support base 2 and the upper part of the bearing housing 4 are used to support and compress the spring 3. The limiting ring at the upper part of the bearing housing 4 is also used to support the first bearing 5.

[0037] Spring 3 is a rectangular spring. Compared with round or other shaped springs 3, rectangular springs have higher elasticity and more stable compression performance, which can provide a longer service life and more consistent pressure distribution while ensuring sufficient pressure.

[0038] The end faces of the support base 2 and the bearing housing 4 have notches that can lock each other in place and provide a certain buffer space. The notches on the end faces of the support base 2 and the bearing housing 4 are evenly distributed. While maintaining the connection stability of the support base 2 and the bearing housing 4, a certain degree of relative movement is allowed, thereby playing a buffering role, reducing the impact of vibration generated during processing on the equipment, and protecting the internal components from damage.

[0039] The second bearing 8 is a thrust ball bearing. Thrust ball bearings can withstand large axial loads and can effectively support the axial loads generated by the pressure during the deburring process, ensuring the stable operation of the entire mechanism and extending its service life.

[0040] Bolt 10 has an internal hexagonal hole at the top, which facilitates the installation and removal of bolt 10. It can be easily operated with an internal hexagonal wrench, making subsequent maintenance and adjustment work convenient.

[0041] The first bearing 5 and the deburring tool 6 are connected by an interference fit, which can ensure synchronous rotation between the tool and the bearing and can withstand certain axial and radial loads.

[0042] The deburring tool 6 is made of cemented carbide to ensure the wear resistance and sharpness of the cutting edge.

[0043] The above embodiments are provided for those skilled in the art to implement or use the present invention. Those skilled in the art can make various modifications or changes to the above embodiments without departing from the inventive concept of the present invention. Therefore, the protection scope of the present invention is not limited to the above embodiments, but should be the maximum scope that conforms to the innovative features mentioned in the claims.
