Description

Technical Field

[0001] The present invention relates to the technical field of grinding machine tools, and more specifically, to an external circle grinding and chamfering device and method for gear processing. Background Art

[0002] The external circle grinding and chamfering device for gears, as a core tool in the field of precision machining, focuses on finely grinding the outer circle edge of gears, aiming to achieve extremely high dimensional accuracy and excellent surface quality. However, in the current production process, the operation efficiency of this device is often limited by the cumbersome and intermittent manual operation.

[0003] Specifically, in the traditional operation mode, workers first need to manually and precisely clamp and fix the gear workpiece using a fixture. This process not only requires a high degree of concentration and skill but also consumes valuable time. Subsequently, the grinding and chamfering machine finely grinds the gear under control. Once the chamfering operation is completed, manual intervention is required for unloading, and the above steps are repeated for loading and fixing the next gear workpiece. This highly manual loading and unloading process is not only cumbersome and time-consuming but also leads to discontinuity in the production process, significantly reducing the overall work efficiency. In view of this, we propose an external circle grinding and chamfering device and method for gear processing. Summary of the Invention

[0025] A method for using an external circle grinding and chamfering device for gear processing includes the following steps:

[0026] S1. During use, it is necessary to cooperate with an external robotic arm. The gear to be processed is clamped and placed in the feeding component by the external robotic arm. After the gear is clamped and fixed by the adjusting component, the robotic arm can be released and then grab the remaining gears and place them again.

[0027] S2. When the external robotic arm finishes clamping the gear and places it outside the adjusting component, the adjusting component will adsorb the gear and drive it to move downward. When the gear contacts the separating component, the adjusting component will release the clamping of the gear. At this time, the gear will free-fall to the bottom of the feeding component. Since when the first driver operates, several connecting plates will move outside the first driver and reciprocate in the form of a conveyor belt. When the connecting plate provided with the positioning component enters below the feeding component, the pressing block will press down the positioning component through the inclined surface due to contact with the lower part of the feeding component, causing the positioning component to contract. After entering the feeding component, the positioning component will reset under the action of elastic force and be located at the installation part in the middle of the gear. At this time, the sealing component will squeeze the gas inside it to the positioning component due to contact with the tooth plate, causing the positioning component to deform while fixing the inside of the gear, thereby driving the gear to slide out of the feeding component and enter the corner grinder along the operation of the first driver.

[0028] S2.1. When the first driver operates, the first driver will drive the connecting plate to circulate outside it, causing the connecting plate to form a conveyor belt outside the first driver. When the pressing block drives the inclined groove in contact with the lower part of the feeding cylinder through the inclined surface, the pressing block will squeeze the sliding cylinder to move into the sliding sleeve due to the pressure when contacting the feeding cylinder. After entering the feeding cylinder, the spring will squeeze the sliding cylinder to reset. At this time, the sliding cylinder and the positioning plate are located at the hollow position of the gear inside the feeding cylinder. As the positioning plate drives the gear to move, it will contact and squeeze the baffle to flip along the pin shaft, thereby taking out the gear to be processed. During this process, the driven gear will contact the baffle on the left, causing the driven gear to rotate and drive the screw rod to rotate at the same time. At this time, the screw rod will move upward under the action of the internal thread of the nut, thereby squeezing the gas in the sealing shell to the sliding sleeve through the piston plate. Subsequently, the gas will enter the air pipe and several telescopic pipes along the air inlet hole.

[0029] S2.2. When the external robotic arm clamps the gear and places it in the feeding cylinder, as the second driver operates, the conveyor will continue to run. At this time, the electromagnetic gripper will adsorb and clamp the gear placed in the feeding cylinder by the external robotic arm. As the conveyor continues to run, the gear will gradually move downward. When the gear contacts the insulating spacer, the insulating spacer will extrude the gear because its shape matches the internal shape of the electromagnetic gripper. At this time, the gear loses adsorption and will directly fall to the bottom of the discharging cylinder under the action of gravity.

[0030] S3. As the first driver operates, after the gear enters the corner grinder along the connecting plate and is processed, the gear will slide out again under the drive of the connecting plate and the positioning component. At this time, the driven gear will contact the right gear, and the driven gear will rotate reversely due to contact with the right tooth plate, causing the lead screw to rotate and move downward in the nut, thereby extracting the air discharged into the telescopic tube. At this time, the positioning plate resets. As the connecting plate moves, when the connecting plate drives the gear to move to the far right and continues to move, the gear will fall into the external collection box when the connecting plate flips due to losing clamping.

[0031] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0032] 1. In the present invention, by designing the positioning component, adjustment component, tooth plate and sealing component, when the external robotic arm finishes clamping the gear and places it outside the adjustment component, the adjustment component will adsorb the gear and drive it to move downward. When the gear contacts the separation component, the adjustment component will release the clamping of the gear. At this time, the gear will free-fall to the bottom of the feeding component. Since when the first driver operates, several connecting plates will move outside the first driver and reciprocate in the form of a conveyor belt. When the connecting plate provided with the positioning component enters below the feeding component, the pressing block will press down the positioning component through the inclined surface due to contact with the lower part of the feeding component, causing the positioning component to contract. After entering the feeding component, the positioning component will reset under the action of elastic force and be located at the installation part in the middle of the gear. At this time, the sealing component will squeeze the gas inside it into the positioning component due to contact with the tooth plate, causing the positioning component to deform while fixing the inside of the gear, thereby driving the gear to slide out of the feeding component and enter the corner grinder along the operation of the first driver, enabling the device to automatically complete the feeding, unloading and corner grinding of the gear only by setting the position of the robotic arm. On the one hand, it reduces the situation of inconsistent gear processing quality caused by human participation in the gear corner grinding process. On the other hand, through the continuous feeding of the external robotic arm, the device can cyclically take out the gears in the feeding component, and can automatically fix and unload, reducing the cumbersome operation process, thereby reducing the time required for processing gears, and further improving the efficiency of the device for processing gears.

[0033] 2. The present invention also designs a sealing component and an extrusion block. When the first driver operates, the first driver drives the connecting plate to circulate outside it, causing the connecting plate to form a conveyor belt outside the first driver. When the extrusion block contacts the inclined groove driven by the lower part of the feeding cylinder through the inclined surface, the extrusion block will squeeze the sliding cylinder to move into the sliding sleeve due to the pressure when contacting the feeding cylinder. After entering the feeding cylinder, the spring will squeeze the sliding cylinder to reset. At this time, the sliding cylinder and the positioning plate are located at the hollow position of the gear inside the feeding cylinder. As the positioning plate drives the gear to move, it will contact and squeeze the baffle to flip along the pin shaft, thereby taking out the gear to be processed. During this process, the driven gear will contact the baffle on the left side, causing the driven gear to rotate and drive the screw rod to rotate. At this time, the screw rod will move upward under the action of the internal thread of the nut, thereby squeezing the gas in the sealing shell through the piston plate into the sliding sleeve. Subsequently, the gas will enter the air delivery pipe and several telescopic pipes along the air inlet hole. Since several telescopic rods will push the positioning plate outward when extending, the positioning plate will automatically clamp and fix the gear, ensuring that the device can guarantee the fixing effect of the gear when positioning the gear and transporting it to the corner grinder for processing, and can be automated without human participation, reducing the cost of human participation in processing gears.

[0034] 3. The present invention also designs a feeding component, an adjusting component and a separating component. When the external robotic arm clamps the gear and places it in the feeding cylinder, as the second driver operates, the conveyor will continue to run. At this time, the electromagnetic gripper will adsorb and clamp the gear placed in the feeding cylinder by the external robotic arm. As the conveyor continues to run, the gear will gradually move downward. When the gear contacts the insulating separator, the insulating separator will extrude the gear because its shape matches the internal shape of the electromagnetic gripper. At this time, the gear loses adsorption and will directly fall to the bottom of the discharging cylinder under the action of gravity, enabling the device to neatly place the materials in the feeding cylinder in sequence by cooperating with the external robotic arm for feeding, and neatly arranging the gears by electromagnetic adsorption, avoiding the difficulty of taking out the gear through the sliding cylinder due to the wrong angle of the gear placed in the feeding cylinder, ensuring the stability of the device during use, and improving the coherence of the device during feeding.

[0054] As Figures 1 to 8As shown, an external cylindrical grinding and chamfering device and method for gear processing according to the present invention include

[0055] The body mechanism 1 includes a body housing 101, support legs 102 provided below the body housing 101, a corner grinder 103, and a first driver 104. Among them, the corner grinder 103 is located above the body housing 101, and the first driver 104 is provided on one side of the body housing 101; and, the conveying mechanism 2 includes a plurality of connecting plates 201, hinges 202 connected to the plurality of connecting plates 201, a positioning assembly 203, a sealing assembly 206, a nut 207 and a toothed plate 209 provided below the sealing assembly 206. Among them, the number of toothed plates 209 is two, the number of positioning assemblies 203 is several, and several positioning assemblies 203 are all provided on the connecting plates 201. The distance between two adjacent positioning assemblies 203 is two connecting plates 201. The sealing assembly 206 is provided below the positioning assembly 203, and the toothed plate 209 overlaps with the sealing assembly 206;And, the feeding mechanism 3 includes a fixed frame 301, a feeding component 302, an adjusting component 303 arranged on one side of the feeding component 302, a separating component 304, and a discharging component 305. Among them, the fixed frame 301 is connected to the feeding component 302, the separating component 304 is fixedly connected inside the adjusting component 303, and the discharging component 305 is arranged below the feeding component 302. By designing the positioning component 203, the adjusting component 303, the toothed plate 209, and the sealing component 206, when the external robotic arm finishes clamping the gear and places it outside the adjusting component 303, the adjusting component 303 will adsorb the gear and drive it to move downward. And when the gear contacts the separating component 304, the adjusting component 303 will release the clamping of the gear. At this time, the gear will free-fall to the bottom of the feeding component 302. Since when the first driver 104 operates, several connecting plates 201 will move outside the first driver 104 and reciprocate in the manner of a conveyor belt. And when the connecting plate 201 provided with the positioning component 203 enters below the feeding component 302, the pressing block 204 will press down the positioning component 203 through the inclined surface 205 due to contacting the lower part of the feeding component 302, causing the positioning component 203 to contract. And after entering the feeding component 302, the positioning component 203 will reset under the action of elastic force and be located at the installation part in the middle of the gear. At this time, the sealing component 206 will squeeze the gas inside it to the positioning component 203 due to contacting the toothed plate 209, causing the positioning component 203 to deform while fixing the inside of the gear. Thus, it drives the gear to slide out of the feeding component 302 and enter the chamfering machine 103 along the operation of the first driver 104, enabling the device to automatically complete the feeding, discharging, and chamfering of the gear only by setting the position of the robotic arm. On the one hand, it reduces the situation of inconsistent gear processing quality caused by human participation in the gear chamfering process. On the other hand, through the continuous feeding of the external robotic arm, the device can cyclically take out the gears in the feeding component 302, and can automatically fix and discharge them, reducing the cumbersome operation process, thereby reducing the time required for processing gears, and further improving the efficiency of the device for processing gears.

[0056] In an embodiment of the present invention, the lower part of the body housing 101 is fixedly connected to the tops of a plurality of support legs 102, the upper part of the body housing 101 is tightly welded to the lower part of the corner grinder 103, the front of the body housing 101 is fixedly connected to the first driver 104, one side of the connecting plate 201 is fixedly connected to the hinge 202, a plurality of connecting plates 201 are hinged to each other through the hinge 202, a plurality of positioning components 203 are respectively arranged above the plurality of connecting plates 201, the top of the positioning component 203 is fixedly connected to the lower part of the pressing block 204, an inclined surface 205 is formed above the pressing block 204, the lower part of the positioning component 203 is communicated with the upper part of the sealing component 206, the lower part of the sealing component 206 is fixedly connected to a plurality of positioning blocks 208, and the lower parts of the plurality of positioning blocks 208 are tightly welded to the upper part of the same nut 207. Two of the sealing components 206 are respectively engaged with two toothed plates 209, and the two toothed plates 209 are arranged oppositely. The connecting plate 201 is arranged inside the body housing 101, and the plurality of connecting plates 201 are in transmission connection with the first driver 104. One of the toothed plates 209 is arranged on the left side of the inner wall of the body housing 101, and the other toothed plate 209 is arranged on the right side of the inner wall of the body housing 101. By designing the feeding component 302, the adjusting component 303 and the separating component 304, when an external robotic arm clamps a gear and places it in the feeding cylinder 3021, as the second driver 3034 operates, the conveyor 3032 will continuously run. At this time, the electromagnetic gripper 3033 will adsorb and clamp the gear placed in the feeding cylinder 3021 by the external robotic arm. And as the conveyor 3032 continuously runs, the gear will gradually move downward. When the gear contacts the insulating separator 3042, the insulating separator 3042 will extrude the gear because its shape matches the internal shape of the electromagnetic gripper 3033. At this time, the gear loses adsorption and will directly fall to the bottom of the discharging cylinder under the action of gravity, so that the device can cooperate with the external robotic arm to place the materials neatly in the feeding cylinder 3021 in sequence after feeding, and neatly arrange the gears by electromagnetic adsorption, avoiding the difficulty of taking out the gear through the sliding cylinder 2032 due to the wrong angle of the gear placed in the feeding cylinder 3021, ensuring the stability of the device during use, and improving the coherence of the device during feeding.

[0057] In an embodiment of the present invention, the positioning component 203 includes a sliding sleeve 2031. A sliding cylinder 2032 is slidably connected inside the sliding sleeve 2031. A sealing plate 2033 is fixedly connected to the bottom end of the sliding cylinder 2032. The upper part of the sealing plate 2033 is fixedly connected to the bottom end of the air delivery pipe 2036. An air inlet hole 2034 is formed below the sealing plate 2033. The sealing plate 2033 is communicated with the air delivery pipe 2036 through the air inlet hole 2034. A spring 2035 is sleeved outside the sliding cylinder 2032. Two ends of the spring 2035 are respectively fixedly connected to the upper part above the sealing plate 2033 and the upper part of the inner wall of the sliding sleeve 2031. The air delivery pipe 2036 is communicated with a plurality of telescopic pipes 2037. The other ends of the plurality of telescopic pipes 2037 respectively pass through the sliding cylinder 2032 and are fixedly connected to a plurality of positioning plates 2038. The plurality of positioning plates 2038 are all clamped outside the sliding cylinder 2032. The top end of the sliding cylinder 2032 is fixedly connected to the lower part of the extrusion block 204.

By designing the sealing component 206 and the extrusion block 204, when the first driver 104 operates, the first driver 104 will drive the connecting plate 201 to circulate outside it, so that the connecting plate 201 forms a conveyor belt outside the first driver 104. When the extrusion block 204 drives the inclined groove 3023 in contact with the lower part of the feeding cylinder 3021 through the inclined surface 205, the extrusion block 204 will extrude the sliding cylinder 2032 to move into the sliding sleeve 2031 due to the pressure when contacting the feeding cylinder 3021. After entering the feeding cylinder 3021, the spring 2035 will extrude the sliding cylinder 2032 to reset. At this time, the sliding cylinder 2032 and the positioning plate 2038 are located at the hollow position of the gear inside the feeding cylinder 3021. As the positioning plate 2038 drives the gear to move, it will contact and extrude the baffle 3053 to flip along the pin shaft 3051, so as to take out the gear to be processed. During this process, the driven gear 2065 will contact the baffle 3053 on the left side, causing the driven gear 2065 to rotate and drive the lead screw 2064 to rotate at the same time. At this time, the lead screw 2064 will move upward under the action of the thread in the nut 207, so as to squeeze the gas in the sealing shell 2061 into the sliding sleeve 2031 through the piston plate 2062. Subsequently, the gas will enter the air delivery pipe 2036 and a plurality of telescopic pipes 2037 along the air inlet hole 2034,Since several telescopic rods will push the positioning plate 2038 outward when extending, the positioning plate 2038 will automatically clamp and fix the gear, ensuring that the device can guarantee the fixing effect of the gear when positioning the gear and then transporting it into the angle grinder 103 for processing, and it can be automated without human participation, reducing the cost of human participation in processing gears.

The feeding component 302 and the adjusting component 303 are both located above several connecting plates 201. The feeding component 302 includes a feeding cylinder 3021. A fixing ring 3022 is fixedly connected to the outside of the feeding cylinder 3021. An inclined slot 3023 is opened on the left side below the feeding cylinder 3021. A discharging slot 3024 is opened on the right side below the feeding cylinder 3021. The feeding cylinder 3021 is fixedly connected to the two fixing frames 301 through the fixing ring 3022. The position of the inclined slot 3023 is adapted to the position of the inclined surface 205 of the extrusion block 204. The discharging component 305 is arranged in the discharging slot 3024. As the first driver 104 operates, when the gear enters the angle grinder 103 along the connecting plate 201 and is processed, the gear will slide out again under the drive of the connecting plate 201 and the positioning component 203. At this time, the driven gear 2065 will contact the right gear. The driven gear 2065 will rotate reversely because it contacts the right toothed plate 209, causing the lead screw 2064 to move downward while rotating in the nut 207, thereby pumping out the air discharged into the telescopic tube 2037. At this time, the positioning plate 2038 resets. As the connecting plate 201 moves, when the connecting plate 201 drives the gear to move to the rightmost side and continues to move, the gear will fall into the external collection box when the connecting plate 201 flips due to losing the clamping, enabling the device to complete automatic release of the clamping and collection of the processed gear, further improving the automation degree of the device while reducing the use difficulty of the device and ensuring the processing efficiency of the gear.

[0059] As another embodiment of the present invention, the adjusting assembly 303 includes a protective housing 3031. Inside the protective housing 3031, a conveyor 3032 is provided. The conveyor 3032 is composed of a chain and a conveyor roller. On one side of the conveyor 3032, a second driver 3034 is provided. Outside the conveyor 3032, a power supply 3035 is provided. A number of electromagnetic grippers 3033 are fixedly connected outside the conveyor 3032. The protective housing 3031 is fixedly connected to the feeding cylinder 3021. The separating assembly 304 includes mounting blocks 3041. The number of mounting blocks 3041 is two, and the two mounting blocks 3041 are fixedly connected to the same insulating spacer 3042. Retaining frames 3043 are fixedly connected to both sides of the insulating spacer 3042. The shape of the insulating spacer 3042 is adapted to the shape of the inner wall of the electromagnetic gripper 3033. The mounting blocks 3041 are fixedly connected inside the feeding cylinder 3021. The discharging assembly 305 includes a pin shaft 3051. A baffle 3053 is fixedly connected outside the pin shaft 3051. A coil spring 3052 is provided outside the pin shaft 3051. The two ends of the coil spring 3052 are respectively fixedly connected to the baffle 3053 and the pin shaft 3051. The pin shaft 3051 is fixedly connected in the discharging groove 3024. The baffle 3053 is hinged to the feeding cylinder 3021 through the pin shaft 3051. The shape of the baffle 3053 is adapted to the shape of the discharging groove 3024. By providing the coil spring 3052 and the baffle 3053, due to the continuous operation of the connecting plate 201, when the connecting plate 201 drives the gear to move through friction, the baffle 3053 can block the gear, avoiding the situation that the gear not connected to the positioning assembly 203 slides out under the drive of the connecting plate 201, ensuring the safety of the device during use;

[0060] Through the cooperation of the spring 2035, it is ensured that the extrusion block 204 can move down stably when contacting the inclined groove 3023 of the feeding cylinder 3021, and after completely entering the feeding cylinder 3021, the elastic force of the spring 2035 can push the extrusion block 204 and the sliding cylinder 2032 to reset. On the one hand, the stability of the movement of the extrusion block 204 is ensured, and on the other hand, it is ensured that the sliding cylinder 2032 can be located inside the gear, ensuring the fixing effect of the positioning plate 2038 on the gear.

[0061] Working principle: This embodiment provides an external circular grinding and chamfering device and method for gear processing. During use, it is necessary to cooperate with an external robotic arm to clamp and place the gear to be processed on the feeding assembly 302 through the external robotic arm. After the gear is clamped and fixed by the adjusting assembly 303, the robotic arm can be released and grab the remaining gears and place them again;

[0062] When the external robotic arm finishes clamping the gear and places it outside the adjustment component 303, the adjustment component 303 will adsorb the gear and drive it to move downward. When the gear contacts the separation component 304, the adjustment component 303 will release the clamping of the gear. At this time, the gear will free-fall to the bottom of the feeding component 302. Since the first driver 104 is running, several connecting plates 201 will move outside the first driver 104 and reciprocate in the form of a conveyor belt. When the connecting plate 201 provided with the positioning component 203 enters below the feeding component 302, the extrusion block 204 will press down the positioning component 203 through the inclined surface 205 due to contact with the lower part of the feeding component 302, causing the positioning component 203 to contract. After entering the feeding component 302, the positioning component 203 will reset under the action of elastic force and be located at the installation part in the middle of the gear. At this time, the sealing component 206 will squeeze the gas inside it to the positioning component 203 due to contact with the tooth plate 209, causing the positioning component 203 to deform while fixing the inside of the gear, thereby driving the gear to slide out of the feeding component 302 and enter the chamfering device 103 along the operation of the first driver 104;

[0063] When the first driver 104 is running, the first driver 104 will drive the connecting plate 201 to circulate outside it, causing the connecting plate 201 to form a conveyor belt outside the first driver 104. When the extrusion block 204 drives the inclined groove 3023 in contact with the lower part of the feeding cylinder 3021 through the inclined surface 205, the extrusion block 204 will squeeze the sliding cylinder 2032 to move into the sliding sleeve 2031 due to the pressure when contacting the feeding cylinder 3021. After entering the feeding cylinder 3021, the spring 2035 will squeeze the sliding cylinder 2032 to reset. At this time, the sliding cylinder 2032 and the positioning plate 2038 are located at the hollow position of the gear in the feeding cylinder 3021. As the positioning plate 2038 drives the gear to move, it will contact and squeeze the baffle 3053 to flip along the pin shaft 3051, thereby taking out the gear to be processed. During this process, the driven gear 2065 will contact the baffle 3053 on the left, causing the driven gear 2065 to rotate and drive the lead screw 2064 to rotate at the same time. At this time, the lead screw 2064 will move upward under the action of the internal thread of the nut 207, thereby squeezing the gas in the sealing shell 2061 to the sliding sleeve 2031 through the piston plate 2062. Subsequently, the gas will enter the air pipe 2036 and several telescopic pipes 2037 along the air inlet hole 2034;

[0064] When the external robotic arm clamps the gear and places it into the loading cylinder 3021, as the second driver 3034 operates, the conveyor 3032 will keep running. At this time, the electromagnetic gripper 3033 will adsorb and clamp the gear placed in the loading cylinder 3021 by the external robotic arm. And as the conveyor 3032 keeps running, the gear will gradually move downward. When the gear contacts the insulating spacer 3042, the insulating spacer 3042 will extrude the gear because its shape matches the internal shape of the electromagnetic gripper 3033. At this time, the gear loses adsorption and will directly fall to the bottom of the discharging cylinder under the action of gravity;

[0065] As the first driver 104 operates, after the gear enters the chamfering machine 103 along the connecting plate 201 and is processed, the gear will slide out again under the drive of the connecting plate 201 and the positioning assembly 203. At this time, the driven gear 2065 will contact the right gear, and the driven gear 2065 will rotate reversely because it contacts the right toothed plate 209, causing the lead screw 2064 to rotate and move downward in the nut 207, thereby pumping out the air discharged into the telescopic tube 2037. At this time, the positioning plate 2038 resets. And as the connecting plate 201 moves, when the connecting plate 201 drives the gear to move to the rightmost side and continues to move, the gear will fall into the external collection box when the connecting plate 201 flips because it loses clamping.

However, as long as they do not depart from the spirit of the present invention, they are within the protection scope of the present invention.

After the gear is clamped and fixed by the adjustment assembly (303), the robotic arm can be released and the remaining gear can be grabbed and placed again; S2. When the external mechanical arm has finished clamping the gear and placed it outside the adjustment component (303), the adjustment component (303) will absorb the gear and drive the gear to move downward, and when the gear contacts the separation component (304), the adjustment component (303) will loosen its grip on the gear, and the gear will fall freely to the bottom of the feeding component (302). When the first driver (104) is running, a plurality of connecting plates (201) will move outside the first driver (104) and reciprocate in the manner of a conveyor belt, and when the connecting plate (201) provided with the positioning component (203) enters below the feeding component (302), the extrusion block (204) The positioning component (203) will be pressed downward by the inclined surface (205) due to contact with the bottom of the feeding component (302), causing the positioning component (203) to shrink. After entering the feeding component (302), the positioning component (203) will be reset under the action of elastic force and located at the installation position in the middle of the gear. At this time, the sealing component (206) will contact the tooth plate (209) and squeeze the internal gas into the positioning component (203), causing the positioning component (203) to deform and fix the inside of the gear, thereby driving the gear to slide out of the feeding component (302) and enter the angle grinder (103) along the operation of the first driver (104); S2.

1. When the first driver (104) is in operation, the first driver (104) drives the connecting plate (201) to circulate outside the first driver (104), so that the connecting plate (201) forms a conveyor belt outside the first driver (104), and when the extrusion block (204) drives the inclined groove (3023) to contact the lower part of the loading barrel (3021) through the inclined surface (205), the extrusion block (204) will squeeze the slide (2032) to move into the sliding sleeve (2031) due to the pressure when it contacts the loading barrel (3021), and after entering the loading barrel (3021), the spring (2035) squeezes the slide (2032) to reset, and at this time, the slide (2032) and the positioning plate (2038) are located in the gear hollow in the loading barrel (3021). and as the positioning plate (2038) drives the gear to move, it contacts the baffle (3053) and squeezes the baffle (3053) to flip along the pin shaft (3051), thereby bringing out the gear to be processed. In this process, the driven gear (2065) contacts the baffle (3053) on the left side, so that the driven gear (2065) rotates and drives the screw rod (2064) to rotate. At this time, the screw rod (2064) moves upward under the action of the internal thread of the nut (207), thereby squeezing the gas in the sealing shell (2061) into the sliding sleeve (2031) through the piston plate (2062). Subsequently, the gas enters the gas delivery pipe (2036) and the plurality of telescopic pipes (2037) along the air inlet hole (2034); S2.2, when the external mechanical arm clamps the gear and places the gear in the upper barrel (3021), as the second driver (3034) operates, the conveyor (3032) will continue to operate. At this time, the electromagnetic clamp (3033) will adsorb and clamp the gear placed in the upper barrel (3021) by the external mechanical arm, and as the conveyor (3032) continues to operate, the gear will gradually move downward. When the gear contacts the insulating isolation sheet (3042), the insulating isolation sheet (3042) will squeeze out the gear due to its shape matching the internal shape of the electromagnetic clamp (3033). At this time, the gear loses adsorption and falls directly to the bottom of the lower barrel under the action of gravity; S3.

At this time, the driven gear (2065) will contact the right gear. The driven gear (2065) will rotate in the opposite direction due to contact with the right tooth plate (209), so that the screw rod (2064) rotates in the nut (207) and moves downward, thereby extracting the air discharged into the telescopic tube (2037). At this time, the positioning plate (2038) is reset, and as the connecting plate (201) moves, when the connecting plate (201) drives the gear to move to the far right and continues to move, the gear will lose its clamping and fall into the external collection box when the connecting plate (201) flips.
