Description

Technical Field

[0001] This utility model relates to an automatic gear polishing mechanism, belonging to the technical field of mechanical automation. Background Technology

[0002] Automated mechanical production technology is inextricably linked to systems engineering, computer technology, electronics, hydraulic and pneumatic technology, and automatic control technology. With the rapid development of industrial automation technology in my country and the increasing demands on automation technology, coupled with the growing national investment in artificial intelligence in recent years, the prevalence of industrial automation is gradually becoming a reflection of a nation's comprehensive strength.

[0003] Gears are commonly used mechanical transmission components. They have teeth on their rims, and the meshing of these teeth transmits power, speed, or direction of motion. Gear polishing is a crucial step in gear finishing, using processes such as grinding, lapping, honing, and chamfering to improve gear precision, surface finish, and performance. Currently, manual polishing is typically done by handheld electric polishers, but this method lacks precision and can easily affect the accuracy of the polished gears. Furthermore, the simple method of fixing gears during operation makes it difficult to ensure stability during polishing, often leaving burrs at the tooth roots after polishing. Therefore, there is an urgent need for an automatic gear polishing mechanism to solve the problems mentioned in the background. Utility Model Content

[0004] The summary section of this application is intended to provide a brief overview of the concepts, which will be described in detail in the detailed description section below. This summary section is not intended to identify key or essential features of the claimed technical solutions, nor is it intended to limit the scope of the claimed technical solutions.

[0005] To address the problems and shortcomings of existing technologies, the purpose of this utility model is to provide an automatic gear polishing mechanism that enables simultaneous operation of three parts: a grinding head polishes the gear end face, a wire brush polishes the inner edges of the gear teeth, and a motor drives the gear to rotate sequentially to the next inner tooth for further polishing. This improves assembly efficiency, increases product yield, and reduces production costs, thereby solving the problems mentioned in the background section.

[0006] To achieve the above objectives, this utility model provides the following technical solution: It includes a gear and a base plate. A motor is connected to the bottom of the base plate, and the output shaft of the motor passes through the base plate and connects to a chuck. A gear fixing post extends into the opening of the chuck, and the gear is sleeved on the outside of the gear fixing post. A rotary cylinder and a sliding cylinder are connected to the top of the base plate via a support seat. Both the rotary cylinder and the sliding cylinder are connected to handheld grinders. The two handheld grinders are respectively connected to a grinding head and a wire brush, and both the grinding head and the wire brush correspond to the gear.

[0007] Preferably, both the rotary cylinder and the slide cylinder are connected to a grinding machine mounting bracket via an adapter plate, and the two grinding machine mounting brackets are respectively connected to the handheld grinding machine. The grinding machine mounting brackets are connected to the slide cylinder and the rotary cylinder via adapter plates, and then the handheld grinding machine is connected to the grinding machine mounting brackets. The grinding machine mounting brackets enhance the stability of the handheld grinding machine during operation, thereby improving the precision of the finished gears.

[0008] Preferably, a retaining ring is also fitted onto the outside of the gear retaining post and secured with screws, with the retaining ring positioned above the gear. After being connected and secured with screws, the retaining ring is fitted onto the outside of the gear retaining post and fixed above the gear. The retaining ring effectively secures the gear's position, preventing rotation during grinding and polishing, thereby further improving the precision of the finished gear.

[0009] Preferably, a protective sleeve is fitted over the outside of the chuck, with the lower end of the protective sleeve connected to the base plate and the upper opening of the protective sleeve fitted over the outside of the chuck. By fitting the protective sleeve over the outside of the chuck and connecting it to the top of the base plate, the protective sleeve not only protects the chuck but also secures it, further improving the stability of the gears during operation.

[0010] Preferably, the thickness of the wire brush does not exceed twice the size of the gear's internal teeth. Because the gear's internal teeth are relatively small, the thickness of the wire brush bristles is set to not exceed twice the size of the gear's internal teeth. That is, within this range of twice the size, the wire brush can effectively clean the rolled edges of the gear's internal teeth.

[0011] Preferably, the gear holder can be replaced according to the size of the gear. Replacement is simple: just remove the existing gear holder from the chuck and install the new gear holder onto the chuck.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This invention features a simple structure and easy operation, enabling automatic grinding and polishing of gears. Specifically, it comprises three synchronously operating parts: a motor-controlled gear rotation for sequential grinding and polishing of the gear's internal teeth; a rotary cylinder driving a wire brush to grind and polish the gear's internal teeth; and a sliding cylinder driving a grinding head to grind and polish the gear's end faces. Furthermore, a grinding machine mounting bracket enhances the stability of the handheld grinder during operation, improving the precision of the finished gear. A retaining ring further secures the gear, preventing rotation during grinding and polishing, thus further enhancing the precision of the finished gear. The gear mounting bracket can be replaced according to the gear's size, increasing its versatility. This invention significantly reduces the physical labor of R&D personnel, improves assembly efficiency, increases product yield, and reduces production costs. Attached Figure Description

While some embodiments of this disclosure are shown in the drawings, it should be understood that this disclosure can be implemented in various forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided to provide a more thorough and complete understanding of this disclosure. It should be understood that the accompanying drawings and embodiments of this disclosure are for illustrative purposes only and are not intended to limit the scope of protection of this disclosure.

[0019] It should also be noted that, for ease of description, only the parts relevant to the utility model are shown in the accompanying drawings. Unless otherwise specified, the embodiments and features described in this disclosure can be combined with each other.

[0020] This disclosure will now be described in detail with reference to the accompanying drawings and embodiments.

[0021] This embodiment provides an automatic gear polishing mechanism, such as... Figure 1 As shown: It includes a gear 5 and a base plate 1. A motor 2 is connected to the bottom of the base plate 1. The output shaft of the motor 2 passes through the base plate 1 and connects to a chuck 4. The opening of the chuck 4 extends into and connects to a gear fixing post 11, and the gear 5 is sleeved on the outside of the gear fixing post 11. A rotary cylinder 3 and a sliding cylinder 7 are connected to the top of the base plate 1 through a support seat. Both the rotary cylinder 3 and the sliding cylinder 7 are connected to hand-held grinders 6. The two hand-held grinders 6 are respectively connected to a grinding head 9 and a wire brush 10. Both the grinding head 9 and the wire brush 10 correspond to the gear 5.

[0022] This embodiment also includes a grinder mounting bracket 8 connected to both the rotary cylinder 3 and the slide cylinder 7 via an adapter plate. The two grinder mounting brackets 8 are respectively connected to a handheld grinder 6. The thickness of the wire brush 10 does not exceed twice the size of the internal teeth of the gear 5. The grinder mounting brackets 8 enhance the stability of the handheld grinder 6 during operation, thereby improving the precision of the finished gear 5. Because the internal teeth of the gear 5 are relatively small, the bristle layer thickness of the wire brush 10 is set to not exceed twice the size of the internal teeth of the gear, so as to cleanly polish the rolled edges of the internal teeth of the gear 5.

[0023] This embodiment also includes a retaining ring fitted onto the gear retaining post 11 and fixed with screws, with the retaining ring positioned above the gear 5. The gear retaining seat 11 can be replaced according to the size of the gear 5. The retaining ring and screws secure the gear 5 in place, preventing rotation during grinding and polishing, thereby further improving the precision of the finished gear 5. When replacing the gear retaining seat 11, simply remove the existing gear retaining seat 11 from the chuck 4 and install the new gear retaining seat 11 on the chuck 4.

[0024] This embodiment also includes a protective sleeve 12 fitted over the outside of the chuck 4. The lower end of the protective sleeve 12 is connected to the base plate 1, and the upper opening of the protective sleeve 12 is fitted over the outside of the chuck 4. The protective sleeve not only protects the chuck but also fixes it, further improving the stability of the gear during operation.

[0025] Method of using this utility model

[0026] The connection of this utility model is as follows: a motor 2 is connected below the base plate 1, and a rotary cylinder 3 is connected above it, with the output shaft of the motor 2 passing through the rotary cylinder 3 on the base plate 1. The output shaft of the rotary cylinder 3 is connected to a chuck 4, and the upper opening of the chuck 4 extends into a gear fixing post 11. A gear 5 is sleeved on the outside of the gear fixing post 11. The gear 5 is locked and firmly fixed to the gear fixing post 11 using a fixing ring and screws (since the fixing ring is a common mechanical component, it is not shown in the attached drawings). A slide cylinder 7 is connected to the top of the base plate 1 via a support base, and the rotary cylinder 3 is also connected via a support base. Both the slide cylinder 7 and the rotary cylinder 3 are equipped with adapter plates to connect to a grinder mounting frame 8, and a handheld grinder 6 is fixedly connected to the grinder mounting frame 8. One handheld grinder 6 is connected to a grinding head 9, and the other handheld grinder 6 is connected to a wire brush 10. The slide cylinder 7 drives one of the handheld grinders 6 and the grinding head 9 to move up and down in a straight line, while the rotary cylinder 3 drives the other handheld grinder 6 and the wire brush 10 to rotate. Specifically, a protective sleeve 12 is fitted over the outside of the chuck 4 and connected to the top of the base plate 1. The protective sleeve 12 protects the chuck 4 and also secures it.

[0027] In the initial preparation stage, after the gear is initially formed on a CNC machine tool, the gear in the rough machining state is removed. First, a gear fixing post 11 that matches the gear is selected, and the gear fixing post 11 is installed in the chuck 4 and locked. Then, the gear 5 to be polished is fitted onto the gear fixing post 11 and locked and fixed to the gear fixing post 11 with screws to prevent the gear 5 from rotating during the polishing process. Finally, the positions of the grinding head 9 and the wire brush 10 are adjusted to ensure that the grinding head 9 can accurately contact the end face of the gear 5, and also to ensure that the wire brush 10 is tangent to the gear 5.

[0028] After the operator completes the above preparations, press the start switch to rotate motor 2. Motor 2 drives gear 5 to rotate, controlling the rotation of gear 5 to polish the internal teeth between the gear teeth. The slide cylinder 7 drives the grinding head 9 to press down and perform the polishing operation on the gear end face, while the rotary cylinder 3 drives the wire brush 10 to rotate and perform the polishing operation on the internal teeth of the gear. Each time the wire brush 10 finishes polishing one gear internal tooth, motor 2 drives gear 5 to rotate to the next gear internal tooth to continue polishing. Motor 2, slide cylinder 7, and rotary cylinder 3 operate sequentially, first polishing the gear end face, then polishing the gear internal teeth. Because the size of the gear internal teeth is small, the thickness of the wire brush 10 cannot exceed twice the size of the gear internal teeth. Within this range, the wire brush 10 can clean the rolled edges of the gear internal teeth.

[0029] In the description of this utility model, it should be understood that the indicated orientation or positional relationship is based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing this utility model and simplifying the description, and is not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0030] In addition to the embodiments described above, this utility model may have other implementation methods. Those skilled in the art can still modify the technical solutions described in the above embodiments, or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
