Description
Technical Field
[0001] This application relates to the field of grinding equipment, and in particular to a gear grinding tool. Background Technology
[0002] A gear is a mechanical component with teeth on its rim that continuously meshes to transmit motion and power. During the production process, gears are usually ground or polished to remove impurities, oxide layers, or defects from their surface.
[0003] Typical grinding tools use a brush and a snap-fit mechanism for connection and fixation, and grind the gears by high-speed rotation. When grinding the gears, the brush will wear and lose bristles because the gear surface has a toothed structure. The snap-fit mechanism also makes it difficult to replace the brush. Summary of the Invention
[0004] To address the aforementioned problems, this application provides a gear grinding tool.
[0005] The gear grinding tool provided in this application adopts the following technical solution:
[0006] A gear grinding tool includes a drive component, a drive shaft, a mounting component, a brush housing, a brush component, a pressing component, and a connecting component. The drive component is connected to the drive shaft and provides drive for the rotation of the drive shaft. The brush housing is inserted into the drive shaft, and the mounting component fixes the brush housing to the drive shaft. The brush housing is divided into two sections: a mounting cylinder and an inner concave shell. The mounting cylinder communicates with the inner concave shell and is inserted into the drive shaft. The brush component is embedded in the inner concave shell. The pressing component covers the brush component and communicates with the mounting cylinder. The connecting component passes through the pressing component and connects to the brush housing.
[0007] By adopting the above technical solution, the driving component provides drive through the driving shaft. The mounting sleeve of the brush shell is fixedly installed on the driving shaft by the mounting component. Then, the brush is embedded in the concave shell, and the pressing component is simultaneously embedded in the concave shell. The pressing component fixes the brush between the pressing component and the concave shell. The position of the pressing component is then fixed by the connecting component, so that the brush can be driven by the driving component and the driving shaft to rotate at high speed to provide gear grinding. When the brush needs to be replaced after long-term use, the pressing component can be opened by the connecting component to remove the brush from the concave shell, thus achieving the function of convenient replacement.
[0008] Optionally, the mounting component has an external thread on its surface, the mounting cylinder has an insertion port, the drive shaft has a threaded hole, and the mounting component passes through the insertion port and is screwed into the threaded hole.
[0009] By adopting the above technical solution, the mounting part is screwed into the threaded hole, so that the mounting cylinder is fixed on the drive shaft by the mounting part. When the drive shaft rotates at high speed, the mounting cylinder will not rotate with it. When it is necessary to separate for maintenance or replacement, the mounting part is unscrewed from the threaded hole and disengaged from the insertion port of the mounting cylinder. The mounting cylinder loses the fixing effect of the mounting part and can be pulled out along the drive shaft.
[0010] Optionally, the inner wall of the mounting cylinder is provided with internal threads, and the connecting member is a connecting bolt, which passes through the pressing member and is screwed to the mounting cylinder.
[0011] By adopting the above technical solution, the connecting bolts are continuously tightened to press the clamping parts, making it impossible for the clamping parts to detach from the connecting bolts. At the same time, the clamping parts will also work with the concave shell to clamp the brush parts, thus fixing the brush parts. When replacement is required, the connecting bolts can be unscrewed from the mounting sleeve to loosen the clamping parts. The clamping parts can be taken out from the concave shell, and the brush parts that have lost their clamping effect can be taken out from the concave shell for replacement.
[0012] Optionally, the brush component has a through-hole, the concave shell has a through-part, and the brush component is inserted into the through-hole and the through-part.
[0013] By adopting the above technical solution, after the through part and the through opening are inserted, the position of the brush part will not deviate when it contacts and grinds the gear. The through part can be used to limit the position and ensure the stability of the brush part during grinding.
[0014] Optionally, the pressing member has a fitting opening, which is inserted into the through part.
[0015] By adopting the above technical solution, the fitting opening allows the through part to be embedded synchronously, so that the position of the pressing part is also fixed by the through part, and the pressing part cannot be loosened during high-speed rotation, thus improving the stability of the connection.
[0016] Optionally, the connector includes an outer pressure plate, a connecting post, and a snap-fit part; the connecting post is installed on the outer pressure plate, and the pressing member is connected to the outer pressure plate through the connecting post; the snap-fit part is connected to the outer pressure plate; the through-hole is hollow inside and has a snap-fit interface; the through-hole extends into the fitting opening and is inserted into the snap-fit part until the snap-fit part snaps into the snap-fit interface.
[0017] By adopting the above technical solution, the snap-fit part gradually snaps into the through part until it snaps into the snap-fit interface. The pressing part can then be pressed onto the brush part by the outer pressure plate and the connecting post, achieving a quick fixing effect.
[0018] Optionally, the number of the through-holes is multiple, and the number of the through-holes, through-holes, fitting holes and snap-fit parts are the same and correspond one-to-one.
[0019] By adopting the above technical solution, and through the cooperation of multiple through-hole parts and snap-fit parts, the multi-point limiting and multi-point fixing functions are achieved, making the installation effect more stable.
[0020] Optionally, the snap-fit portion is pivotally connected to the outer pressure plate and extends outward from the end of the outer pressure plate away from the through portion.
[0021] By adopting the above technical solution, the snap-fit part rotates along the outer pressure plate and disengages from the snap-fit interface during rotation, thereby causing the outer pressure plate and the pressing part to lose their fixing effect, making it convenient to disassemble and replace the new brush part.
[0022] In summary, this application includes at least one of the following beneficial technical effects:
[0023] 1. The drive unit provides drive through the drive shaft. The mounting sleeve of the brush shell is fixedly installed on the drive shaft by the mounting component. Then, the brush is embedded in the inner concave shell, and the pressing component is simultaneously embedded in the inner concave shell. The pressing component fixes the brush between the pressing component and the inner concave shell. The position of the pressing component is fixed by the connecting component, so that the brush can be driven by the drive unit and the drive shaft to rotate at high speed to provide gear grinding. When the brush needs to be replaced after long-term use, the pressing component can be opened by the connecting component to remove the brush from the inner concave shell, so as to achieve the purpose of convenient replacement.
[0024] 2. The mounting part is screwed into the threaded hole, so that the mounting cylinder is fixed on the drive shaft by the mounting part. When the drive shaft rotates at high speed, the mounting cylinder will not rotate with it. When it is necessary to separate for maintenance or replacement, the mounting part is unscrewed from the threaded hole and disengaged from the insertion port of the mounting cylinder. The mounting cylinder loses the fixing effect of the mounting part and can be pulled out along the drive shaft.
[0025] 3. The connecting bolts are continuously tightened to press the clamping parts, making it impossible for the clamping parts to come off the connecting bolts. At the same time, the clamping parts will work with the inner concave shell to clamp the brush parts, thus fixing the brush parts. When replacement is required, the connecting bolts can be unscrewed from the mounting sleeve to loosen the clamping parts. The clamping parts can be taken out from the inner concave shell, and the brush parts that have lost their clamping function can be taken out from the inner concave shell for replacement.
[0026] 4. After the through part and the through opening are inserted, the position of the brush part will not deviate when it contacts and grinds the gear. The through part can be used to limit the position and ensure the stability of the brush part during grinding. Attached Figure Description

[0036] The following is in conjunction with the appendix Figure 1 - Appendix Figure 3 This application will be described in further detail below.
[0037] This application discloses a gear grinding tool.
[0038] A gear grinding tool, reference Figure 1 As shown, it includes a drive component 1, a drive shaft 2, a mounting component 3, a brush housing 4, a brush component 5, a pressing component 6, and a connecting component 7. The drive component 1 is connected to the drive shaft 2 and provides the drive for the rotation of the drive shaft 2. The drive component 1 can be a drive motor, and the drive shaft 2 is connected to the drive end of the drive motor, so that the drive motor can drive the drive shaft 2 to rotate at high speed.
[0039] The brush housing 4 is inserted into the drive shaft 2. The mounting part 3 fixes the brush housing 4 and the drive shaft 2 in place, so that the brush housing 4 and the drive shaft 2 will not separate. When the drive shaft 2 rotates at high speed, it can drive the brush housing 4 to rotate synchronously, and the mounting part 3 makes the brush housing 4 stably connected.
[0040] The brush housing 4 is divided into two sections: a mounting cylinder 41 and an inner concave shell 42. The mounting cylinder 41 and the inner concave shell 42 are connected, and the mounting cylinder 41 is inserted into the drive shaft 2. The inner diameter of the mounting cylinder 41 matches the outer diameter of the drive shaft 2, so that the drive shaft 2 can be inserted into the mounting cylinder 41. Then, the drive shaft 2 and the mounting cylinder 41 are fixed by the mounting piece 3, thereby achieving synchronous drive.
[0041] The brush part 5 is embedded in the concave shell 42. The brush part 5 is the brush body, with several bristles distributed out. The roots of all the bristles are tied together and embedded in the concave shell 42. The pressing part 6 covers the brush part 5. The pressing part 6 can be a pressing cover. The pressing cover presses the brush part 5 into the concave shell 42. At the same time, the pressing cover has a pressing opening, which is connected to the mounting cylinder 41.
[0042] The connector 7 passes through the press-fitting part 6 and can be connected to the brush. The function of the connector 7 is to fix the press-fitting part 6 so that the press-fitting part 6 presses down on the brush part 5, so as to prevent the brush part 5 from being dispersed when it rotates at high speed or comes into contact with gears for grinding. It also serves to hold the brush part 5 between the press-fitting part 6 and the brush shell 4.
[0043] Specifically, the drive component 1 provides drive through the drive shaft 2. The mounting sleeve 41 of the brush housing 4 is fixedly mounted on the drive shaft 2 through the mounting component 3. Then, the brush component 5 is embedded in the concave shell 42, and the pressing component 6 is simultaneously embedded in the concave shell 42. The pressing component 6 fixes the brush component 5 between the pressing component 6 and the concave shell 42. The position of the pressing component 6 is then fixed through the connecting component 7, so that the brush component 5 can be driven by the drive component 1 and the drive shaft 2 to rotate at high speed to provide gear grinding. When the brush component 5 needs to be replaced after long-term use, the pressing component 6 can be opened through the connecting component 7 to remove the brush component 5 from the concave shell 42, so as to achieve convenient replacement.
[0044] Furthermore, the surface of the mounting part 3 is provided with external threads, and the mounting part 3 can be equipped with mounting bolts, with the external threads on the outer surface providing screw fastening.
[0045] The mounting cylinder 41 has an insertion port 411, and the drive shaft 2 has a threaded hole. The mounting part 3 passes through the insertion port 411 and is screwed into the threaded hole. By screwing the mounting part 3 into the threaded hole, the mounting cylinder 41 is fixed to the drive shaft 2. When the drive shaft 2 rotates at high speed, the mounting cylinder 41 will not rotate with it. When it is necessary to separate for maintenance or replacement, the mounting part 3 is unscrewed from the threaded hole and disengaged from the insertion port 411 of the mounting cylinder 41. The mounting cylinder 41 loses the fixing effect of the mounting part 3 and can be pulled out along the drive shaft 2.
[0046] Furthermore, the inner wall of the mounting cylinder 41 is provided with internal threads, and the connecting part 7 is a connecting bolt 71. The connecting bolt 71 passes through the pressing part 6 and is screwed into the mounting cylinder 41. After the internal threads are provided in the mounting cylinder 41, the connecting bolt 71 can be continuously screwed into it. The connecting bolt 71 continuously tightens the pressing part 6, so that the pressing part 6 cannot be separated from the connecting bolt 71. At the same time, it will also work with the inner concave shell 42 to clamp the brush part 5, thereby fixing the brush part 5. When replacement is required, the connecting bolt 71 can be unscrewed out of the mounting cylinder 41 to loosen the pressing part 6. The pressing part 6 can be taken out from the inner concave shell 42, and the brush part 5, which has lost its clamping effect, can be taken out from the inner concave shell 42 for replacement.
[0047] Further, refer to Figure 2 As shown, the brush 5 has a through-hole 51 and the inner concave shell 42 has a through-hole 421. The brush 5 is inserted into the through-hole 421 through the through-hole 51. After the through-hole 421 is inserted into the through-hole 51, the position of the brush 5 will not deviate when it is grinding the gear. It can be limited by the through-hole 421 to ensure the stability of the brush 5 during grinding.
[0048] Furthermore, refer to Figure 2 or Figure 3As shown, the pressing part 6 has a fitting opening 61, which is inserted into the through part 421. The fitting opening 61 allows the through part 421 to be inserted synchronously, so that the position of the pressing part 6 is also fixed by the through part 421, and the pressing part 6 cannot loosen during high-speed rotation, thus improving the stability of the connection.
[0049] In another embodiment, reference Figure 2 and Figure 3 As shown, the connector 7 includes an outer pressure plate 72, a connecting post 73, and a snap-fit part 74; the connecting post 73 is installed on the outer pressure plate 72, and the pressing part 6 is connected to the outer pressure plate 72 through the connecting post 73. The connecting post 73 provides the gap between the pressing part 6 and the outer pressure plate 72. Several connecting posts 73 can be provided to ensure the stability of the connection.
[0050] The snap-fit part 74 is connected to the outer pressure plate 72. The through part 421 passes through the fitting opening 61 and snaps into the snap-fit part 74. The snap-fit part 74 can be a snap-fit post with elasticity, and has tapered snap-fit protrusions on both sides.
[0051] The through part 421 is hollow inside and has a locking interface 4211. The through part 421 extends into the fitting opening 61 and is inserted into the locking part 74 until the locking part 74 locks into the locking interface 4211. When the conical locking protrusion is in contact with the opening of the through part 421, the conical surface contacts the opening and squeezes the locking protrusion, causing the locking protrusion to shrink. When it moves to the locking interface 4211, it loses the pressing effect of the inner wall of the through part 421 and unfolds, thereby locking into the locking interface 4211, thus fixing the outer pressure plate 72 and the pressing part 6.
[0052] Furthermore, the number of through-holes 421 is provided, and the number of through-holes 421, through-holes 51, fitting holes 61 and snap-fit parts 74 are the same and correspond one to one. Through the cooperation of multiple through-holes 421 and snap-fit parts 74, the function of multi-point limiting and multi-point fixing is achieved, making the installation effect more stable.
[0053] Furthermore, the snap-fit part 74 is pivotally connected to the outer pressure plate 72 and extends outward from the end of the outer pressure plate 72 away from the through part 421. The function of the pivotal connection is that the snap-fit part 74 rotates along the outer pressure plate 72 and disengages from the snap-fit interface 4211 when rotating, so that the outer pressure plate 72 and the pressing part 6 lose their fixing effect, making it convenient to disassemble and replace the new brush part 5.
[0054] This method involves first pressing the outer pressure plate 72 and the pressing part 6 towards the inner concave shell 42, so that the snap-fit part 74 is partially disengaged from the snap-fit interface 4211, and then rotating until the snap-fit part 74 is completely disengaged from the snap-fit interface 4211. This makes the snap-fit part 74 disengage more smoothly, and the connecting part 7 and the pressing part 6 can more easily loosen the brush part 5.
[0055] The embodiments described in this specific implementation are preferred embodiments of this application and are not intended to limit the scope of protection of this application. Identical components are represented by the same reference numerals. Therefore, all equivalent changes made to the structure, shape, and principle of this application should be covered within the scope of protection of this application.
