Description

Technical Field

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

[0002] Burrs are tiny protrusions or flashes formed on the tooth surface, tooth tip, and tooth root during gear machining. Deburring is an important process in gear machining, as it can improve the precision and transmission performance of gears, prevent burrs from affecting the meshing accuracy of gears, make gear transmission smoother and more accurate, and reduce vibration and noise. It can also improve the surface quality of gears, prevent burrs from scratching the surfaces of mating parts, and improve the reliability and service life of gear systems.

[0003] Chinese Patent Publication No. CN220739691U discloses a burr removal mechanism for gear processing, comprising a supporting rotating structure, processing teeth, an adjusting moving structure, and a lifting cleaning structure.

Detailed Implementation

[0022] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0023] Reference Figure 1-5A burr removal mechanism for gear processing includes a support base 1, a three-jaw chuck 2 fixedly mounted on the top of the support base 1, and a cleaning assembly 3 disposed on the top of the support base 1. The cleaning assembly 3 includes a support slide 301, a movable slide 302, a lead screw 303, a support platform 304, a limiting slider 305, a connecting slider 306, a rotary motor 307, a grinding disc 308, a protective cover 309, and a stepper motor 310. The support slides 301 are arranged in parallel on the top of the support base 1, and the movable slides 302 are located on the top of the support base 1 and between the support slides 301. The lead screw 303 is rotatably connected to the movable slide 302. The top of the support platform 304 is slidably connected to the top of the support base 1. The limiting sliders 305 are fixedly connected to the bottom of the support platform 304 in parallel distribution. The connecting slider 306 is fixedly connected to the bottom of the support platform 304 and located between the limiting sliders 305. The rotary motor 307 is fixedly installed on the right side of the support platform 304. The output end of the rotary motor 307 extends through to the left side of the support platform 304. The grinding disc 308 is threadedly connected to the output end of the rotary motor 307. The protective cover 309 is threadedly connected to the left side of the support platform 304 and located outside the grinding disc 308. The stepper motor 310 is fixedly installed on the right side of the support base 1.

[0024] Limiting slider 305 is adapted to support slide 301, connecting slider 306 is adapted to moving slide 302 and threadedly connected to lead screw 303, and stepper motor 310 is drivenly connected to lead screw 303.

[0025] The installation of the three-jaw chuck 2 secures the gear by supporting the inner ring of the gear. The grinding disc 308 grinds the surface of the gear, removing burrs. The protective cover 309, larger than the three-jaw chuck 2, covers its outer side. The cleaning component 3 is set up by starting the stepper motor 310, which rotates the output end of the stepper motor 310 and drives the lead screw 303 to rotate. During the rotation of the lead screw 303, due to the threaded connection with the connecting slider 306 and the adaptation of the limiting slider 305 with the support groove 301, the support platform 304 moves closer to the three-jaw chuck 2 with the fixed gear until the protective cover 309 completely covers the three-jaw chuck. On the outside of disc 2, the rotary motor 307 is then started to drive the grinding disc 308 to rotate, and as the support platform 304 moves, the surface of the gear is ground to remove burrs. The debris generated during the grinding process is blocked by the protective cover 309. In this utility model, the stepper motor 310 drives the lead screw 303 to rotate, which causes the support platform 304 to move. During the movement, the rotary motor 307 drives the grinding disc 308 to grind the surface of the gear, thereby effectively removing burrs from the gear surface. Furthermore, the installation of the protective cover 309 can collect the debris generated during the grinding process, preventing debris from flying and improving the safety of workers in deburring operations.

[0026] Furthermore, the protective cover 309 has a positive thread 3091 on the right side and a negative thread 3092 on the right inner wall of the support platform 304. The positive thread 3091 and the negative thread 3092 are compatible. A baffle 3093 is fixedly connected to the left inner wall of the protective cover 309.

[0027] The installation of baffle 3093 can reduce the diameter of the left side of protective cover 309, thereby preventing debris from falling and facilitating the collection of debris; the opening of positive thread 3091 and negative thread 3092 makes it convenient for workers to disassemble protective cover 309, thereby making it easier for workers to clean the debris inside protective cover 309.

[0028] Furthermore, the three-jaw chuck 2 includes an outer cover 201. The inner right side wall of the outer cover 201 is provided with a limiting groove 202 in a circular array. The limiting groove 202 is slidably connected to a limiting slider 203. A toggle rod 204 is fixedly connected to the left side of the limiting slider 203.

[0029] A self-locking motor 205 is fixedly installed on the left side of the outer cover 201. The output end of the self-locking motor 205 extends into the interior of the outer cover 201. A transmission disk 206 is fixedly connected to the output end of the self-locking motor 205. The inner wall of the transmission disk 206 is provided with transmission grooves 207 arranged in a ring array. The transmission grooves 207 are adapted to the toggle lever 204.

[0030] The opposite side of the limiting slider 203 is arc-shaped, which can improve the contact with the inner ring of the gear and avoid damage to the inner ring of the gear. The transmission groove 207 is arc-shaped. By starting the self-locking motor 205, the self-locking motor 205 drives the transmission disk 206 at the output end to rotate. During the rotation of the transmission disk 206, the transmission groove 207 on the inner wall moves the actuating rod 204, thereby causing the limiting slider 203 to move. During the movement, the limiting slider 203 can support the inner ring of the gear and fix the gear, thus improving the safety of gear placement.

[0031] Furthermore, a support block 4 is fixedly connected to the left side of the support platform 304, and support columns 5 are fixedly connected to the bottom of the support base 1 in a rectangular array. Anti-slip pads 6 are fixedly connected to the bottom of the support columns 5.

[0032] The installation of support block 4 increases the safety of support platform 304, and the installation of anti-slip pad 6 increases friction with the anti-slip surface, thereby improving the safety and stability of the device.

[0033] In summary:

[0034] When using the device, first place it in a suitable position and install the grinding disc 308 and the protective cover 309.

[0035] Then, the gear is placed outside the limiting slider 203, and the self-locking motor 205 is started, so that the self-locking motor 205 drives the transmission disk 206 at the output end to rotate. During the rotation of the transmission disk 206, the transmission groove 207 on the inner wall moves the actuating rod 204, thereby causing the limiting slider 203 to move. During the movement, the limiting slider 203 can support the inner ring of the gear and fix the gear.

[0036] Finally, the stepper motor 310 is started, causing the output end of the stepper motor 310 to rotate while driving the lead screw 303 to rotate. During the rotation of the lead screw 303, due to the threaded connection with the connecting slider 306 and the adaptation of the limiting slider 305 with the support groove 301, the support platform 304 is driven to move closer to the three-jaw chuck 2 with the fixed gear until the protective cover 309 completely covers the outside of the three-jaw chuck 2. Then, the rotary motor 307 is started to drive the grinding disc 308 to rotate, and as the support platform 304 moves, the surface of the gear is ground to remove burrs. The debris generated during the grinding process is blocked by the protective cover 309 to prevent debris from flying.
