DETAILED DESCRIPTION
[0019] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.
[0020] Reference Figure 1 The present invention provides a grinding tool for gear production, which mainly includes an operating table 1, on which are disposed a slide 2, a grinding mechanism 3, a gear rack 4, and a baffle 5. The gear rack 4 is provided in the middle of the slide 2 for placing the gear to be ground. The grinding mechanism 3 is provided on one side of the gear rack 4 and is responsible for grinding the gear. The baffle 5 is provided on the other side of the gear rack 4.
[0021] Reference Figure 2The grinding mechanism 3 includes a grinding bracket 301 , on which a gear pressing block 303 is slidably provided. A lifting cylinder 302 is installed on the top of the grinding bracket 301, and the piston rod of the lifting cylinder 302 is connected to the gear pressing block 303. Driven by the lifting cylinder 302, the gear pressing block 303 can move up and down, pressing the gear on the gear frame 4. A propulsion support plate 304 is slidably installed on the grinding bracket 301 below the gear pressing block 303, and a grinding motor 306 and a propulsion cylinder 305 are installed on the propulsion support plate 304. The grinding motor 306 and the propulsion support plate 304 are slidingly connected, and the cylinder body of the propulsion cylinder 305 is fixedly connected to the propulsion support plate 304, and its piston rod is connected to the grinding motor 306. Driven by the propulsion cylinder 305, the grinding motor 306 can move horizontally on the propulsion support plate 304, so that the folding brush 6 assembled on its output shaft is inserted into the shaft hole of the gear for grinding. An electric push rod is also installed at the bottom of the operating table 1 for pushing the propulsion support plate 304 to move up and down, so that the output shaft of the grinding motor 306 is coaxial with the gear on the gear rack 4 to adapt to gears of different specifications.
[0022] Reference Figure 3 The folding brush 6 includes a telescopic tube 601 and a plurality of polishing support plates 609. A connecting piece 608 is installed between the polishing support plate 609 and the end of the telescopic tube 601. The two ends of the connecting piece 608 are respectively hinged to the polishing support plate 609 and the telescopic tube 601. The polishing support plate 609 is also provided with a detachable polishing sheet 611 for easy replacement and maintenance. At the same time, it is also possible to select the appropriate polishing sheet material and particle size according to different polishing requirements to further improve the polishing effect. A slidable slip ring 606 is sleeved on the telescopic tube 601. A push rod 607 is installed between the slip ring 606 and the connecting piece 608. One end of the push rod 607 is hinged to the slip ring 606, and the other end is rotatably connected to the middle of the connecting piece 608. The slip ring 606 slides on the telescopic tube 601 to open or close the polishing support plate 609 to the telescopic tube 601 through the push rod 607. A rotating portion 605 is provided at one end of the telescopic tube 601 adjacent to the baffle 5. A connecting rod 602 is also mounted within the telescopic tube 601. One end of the connecting rod 602 is connected to the output shaft of the grinding motor 306, and the other end is slidably disposed within the telescopic tube 601. A strip-shaped through-hole 604 is formed in the telescopic tube 601, and a guide block 603 is fixed to the connecting rod 602. The guide block 603 passes through the strip-shaped through-hole 604 and is connected to the slip ring 606. A tension spring 610 is installed between the guide block 603 and one end of the telescopic tube 601.
[0023] In order to facilitate the understanding of the present invention, the following Figure 1 - Figure 3 The working principle of this solution is described in detail:
[0024] Before grinding, the gear rolls down along the slide 2 into the gear frame 4, and the gear pressure block 303 descends to fix it. When the folding brush 6 is not expanded, the grinding support plate 609 is in a retracted state, and the propulsion cylinder 305 pushes the folding brush 6 into the gear shaft hole; when the rotating part 605 contacts the baffle 5, the connecting rod 602 pushes the slip ring 606 so that the grinding support plate 609 will be expanded and close to the inner wall of the gear shaft hole, and the grinding motor 306 rotates to grind the gear shaft hole. In actual application, the rotating part 605 can be selected from components such as thrust ball bearings to reduce the friction between the telescopic tube 601 and the baffle 5; it is also conceivable that a positioning device can also be provided on the baffle 5 to position the rotating part 605 so as to improve the concentricity of the output shaft of the grinding motor 306 and the gear, making the grinding process more stable; in addition, by adjusting the distance between the baffle 5 and the gear frame 4, the expansion degree of the grinding support plate 609 can be adjusted to adapt to gear holes of different specifications;
[0025] The grinding support plate 609 is limited by the piston rod stroke of the propulsion cylinder 305. By adjusting the position of the propulsion cylinder 305 on the propulsion support plate 304 or replacing the propulsion cylinder 305 with a different stroke, the opening range of the grinding support plate 609 can be adjusted.
[0026] Reference Figure 4 The gear rack 4 comprises a support 401 and two U-shaped plates 404 on either side. The spacing between the two U-shaped plates 404 is adjustable to accommodate gears of varying thicknesses, ensuring that the gears that roll into them remain vertical. Two gear shafts 405 are positioned between the two U-shaped plates 404 to support and position the gears, preventing them from rotating during grinding. A blanking wedge 403 is positioned between the two gear shafts 405, and a blanking cylinder 402 is mounted at the bottom of the support 401 to drive the blanking wedge 403 for automatic blanking.
[0027] The specific embodiments of the present invention described above do not limit the scope of protection of the present invention. Any other corresponding changes and modifications made based on the technical concept of the present invention should be included in the scope of protection of the claims of the present invention.
