Description

Technical Field

[0001] This invention relates to an automatic loading and unloading processing device for a bearing inner ring groove grinding machine, belonging to the field of industrial automation processing. Background Technology

[0002] In the context of intelligent upgrading in the manufacturing industry, intelligent automated processing equipment is gradually replacing traditional processing equipment that requires a lot of manpower.

[0003] As one of the most common components in industry, the method of manufacturing bearings is related to the production efficiency and cost of bearings. The bearing inner ring is an important component of bearings. At present, many processing enterprises still use manual clamping and loading or semi-automatic loading and unloading to process the bearing inner ring. This results in low processing efficiency and more labor costs. In addition, the bearing inner ring is at a high temperature after grinding, which may also cause injury to the operators. Summary of the Invention

[0006] It also includes a correction conveyor belt section 5, which is used to correct the misaligned inner ring of the bearing to be processed on the slant conveyor belt section 4.

[0007] The primary screening conveyor belt section 1 is provided with a multi-stage primary screening mechanism section 3. The multi-stage primary screening mechanism section 3 includes multiple primary screens and an anti-overflow front baffle 301. Each primary screen is fixed to the pre-reserved fixing groove 110 on the raised rear baffle 108 on both sides of the primary screening conveyor belt section 1 by primary screen fixing screws 109 through the screw holes on both sides. Each primary screen can be adjusted within the fixing groove 110 according to the inner ring of the bearing to be processed with different thicknesses and sizes. The vertical distance between the multiple primary screens and the primary screening conveyor belt body 106 in the primary screening conveyor belt section 1 decreases step by step along the forward direction.

[0008] The primary screening conveyor belt section 1 includes a primary screening conveyor belt body 106, which is driven by a primary screening conveyor belt drive motor 101 mounted on the primary screening drive load plate 102 through a two-stage reduction of the primary screening conveyor belt drive belt 104 and the primary screening conveyor belt drive pulley 103. Its running direction is to transport the inner ring of the bearing to be processed on the primary screening conveyor belt section 1 to the inclined conveyor belt section 4. Furthermore, primary screening conveyor belt baffles 105, heightened front baffles 107, and heightened rear baffles 108 are installed on both sides of the primary screening conveyor belt section 1.

[0009] The inclined conveyor belt section 4 includes an inclined conveyor belt body 401.

The corrective conveyor belt body 502 has an upper corrective conveyor belt baffle 504 on its upper side and a lower corrective conveyor belt baffle 503 on its lower side. A corrective conveyor belt transition baffle 513 is installed below the lower corrective conveyor belt baffle 503, and a corrective conveyor belt transition baffle extension baffle 514 is installed in front of the corrective conveyor belt transition baffle 513.

[0011] The lower baffle 503 of the correction conveyor belt is connected to the bearing plate 511 of the correction conveyor belt on both sides by two sets of double slider guide rails 501 and heightening blocks 512, and there is a correction conveyor belt screw slide 510 in the middle connected to the bearing plate 511 of the correction conveyor belt. The correction conveyor belt screw slide 510 is driven by a handwheel 509.

[0012] The feeding conveyor belt section 6 includes a feeding conveyor belt body 608. The feeding conveyor belt body 608 is driven by a feeding conveyor belt drive motor 606, which reduces speed twice via a feeding conveyor belt drive belt 603 and a feeding conveyor belt drive pulley 604. The direction of movement is to transport the inner ring of the bearing to be processed forward. The left side of the feeding conveyor belt body 608 is a left baffle 607, and the right side of the feeding conveyor belt body 608 is a right baffle 610. The right baffle 610 has a rectangular feeding groove 609.

[0013] The processing fixture part 8 includes a fixture support 801, a fixture base 802, and an electromagnetic adsorption ring 804, a side top block 806, and a bottom top block 803 installed on the fixture base 802; a roller 805 is respectively on the side top block 806 and the bottom top block 803, and the fixture base 802 is installed on the fixture support 801.

[0014] The triangular loading and unloading integrated mechanism 9 includes a triangular loading and unloading plate 901. Annular electromagnets 902 are respectively installed at the three corners of the triangular loading and unloading plate 901. Each annular electromagnet 902 contains three electromagnet rings with different diameters: a first electromagnet ring 910, a second electromagnet ring 911, and a third electromagnet ring 912. The triangular loading and unloading plate 901 is driven by a triangular loading and unloading plate drive motor 905, and the annular electromagnets 902 are powered by a power supply control device 903.

The triangular loading and unloading integrated mechanism moving control motor 906 is fixed by the triangular loading and unloading integrated mechanism moving control motor bracket 907.

[0015] The beneficial effects of this invention are:

[0016] 1. Compared with existing devices, this invention has a higher level of automation and higher loading and unloading efficiency. By coordinating different conveyor belt sections, a batch of bearing inner rings to be processed, randomly poured into the beginning of the primary screening conveyor belt, can be transformed at the outlet of the loading conveyor belt into a state where the end face is parallel to the right baffle of the loading conveyor belt, and there is no overlap in the radial and axial directions, and they are arranged in an orderly manner at a certain interval. Then, through the unique triangular structure of the triangular loading and unloading integrated device, the bearing inner rings to be processed at the loading trough of the loading conveyor belt and the bearing inner rings already processed in the processing fixture can be simultaneously adsorbed. And through rotational motion, the bearing inner rings to be processed at the loading trough are sent to the processing fixture to complete the loading, while the bearing inner rings already processed in the processing fixture are sent to the unloading guide rail to complete the unloading.

[0017] 2. The present invention incorporates a design in the multi-stage primary screening mechanism, the correction conveyor belt section, the feeding conveyor belt section, and the triangular loading and unloading integrated mechanism section that can be adjusted according to the different radial and thickness dimensions of the inner ring of the bearing to be processed. This design can adapt to batches of inner rings of bearings with different radial and thickness dimensions within a certain range, and has stronger compatibility compared to existing devices.

[0018] 3. By adding rollers to the side top block and bottom top block in the machining fixture part, the present invention can greatly reduce the wear on the machined surface and give the machined bearing inner ring a better surface quality. Attached Figure Description

Detailed Implementation

[0032] The invention will be further described below with reference to the accompanying drawings and embodiments, but the scope of the invention is not limited to the description.

[0033] Example 1: As Figure 1-12As shown, an automatic loading and unloading processing device for a bearing inner ring groove grinding machine includes: a primary screening conveyor belt section 1, an inclined conveyor belt section 4, a correction conveyor belt section 5, a loading conveyor belt section 6, a triangular loading and unloading integrated mechanism section 9, and a processing fixture section 8. The primary screening conveyor belt section 1 transports the bearing inner ring to be processed to the inclined conveyor belt section 4, and the inclined conveyor belt section 4 transports the bearing inner ring to be processed from the inclined conveyor belt section 4 to the loading conveyor belt section 6. The triangular loading and unloading integrated mechanism section 9 adsorbs the bearing inner ring to be processed transported on the loading conveyor belt section 6, and simultaneously adsorbs the already processed bearing inner ring on the processing fixture section 8. After rotational motion, a new bearing inner ring to be processed is loaded onto the processing fixture section 8, and the previously processed bearing inner ring is unloaded into the unloading box 11 via the unloading guide rail 10. Furthermore, the bearing inner ring to be processed is loaded onto the processing fixture section 8, processed by a grinding tool on the grinding machine processing unit 7, and then moved away from the processing fixture section 8 after processing.

[0034] Furthermore, it also includes a correction conveyor belt section 5, which is used to correct the misaligned inner ring of the bearing to be processed on the slant conveyor belt section 4.

[0035] Furthermore, the primary screening conveyor belt section 1 is provided with a multi-stage primary screening mechanism section 3. The multi-stage primary screening mechanism section 3 includes multiple primary screens and an anti-overflow front baffle 301. Each primary screen is fixed to the pre-reserved fixing groove 110 on the raised rear baffle 108 on both sides of the primary screening conveyor belt section 1 by primary screen fixing screws 109 through the screw holes on both sides. Each primary screen can be adjusted within the fixing groove 110 according to the inner ring of the bearing to be processed with different thicknesses and sizes. Moreover, the vertical distance between the multiple primary screens and the primary screening conveyor belt body 106 in the primary screening conveyor belt section 1 decreases step by step along the forward direction. In an embodiment of the present invention, the multi-stage primary screening mechanism is a three-stage primary screening mechanism, which consists of an anti-overflow front baffle 301, a first-stage primary screen 302, a second-stage primary screen 303, and a third-stage primary screen 304. The anti-overflow front baffle 301 is installed at the inlet of the first-stage primary screen 302. The first-stage primary screen 302, the second-stage primary screen 303, and the third-stage primary screen 304 are respectively fixed to the pre-reserved fixing grooves 110 on the raised rear baffles 108 on both sides of the primary screening conveyor belt 1 using primary screen fixing screws 109 through their respective screw holes. The vertical distance between the first-stage primary screen 302, the second-stage primary screen 303, the third-stage primary screen 304 and the primary screening conveyor belt 106 decreases progressively (in addition, each primary screen can be adjusted within the fixing groove 110 range according to the inner ring of the bearing to be processed with different thicknesses). Figure 4As shown, in the multi-stage primary screening mechanism 3, the first-stage primary screen 302, the second-stage primary screen 303, and the third-stage primary screen 304 are trapezoidal (optionally, the first-stage primary screen 302 is a right-angled trapezoid with the side where the anti-overflow front baffle 301 is installed as the right-angled leg, the second-stage primary screen 303 is an isosceles trapezoid, and the third-stage primary screen 304 is a right-angled trapezoid with the leg closest to the inclined conveyor belt 4 as the right-angled leg), and their screening parts are made of hard brushes, which can provide sufficient screening force without damaging the inner ring of the bearing to be processed. Furthermore, the trapezoidal design of each stage ensures that the inner ring of the bearing to be processed will not get stuck on a certain stage during the screening process. Each primary screen is equipped with... The threaded holes are fixed to the pre-reserved fixing grooves 110 on the raised back baffles 108 on both sides of the primary screening conveyor belt section 1. Each primary screening stage can be adjusted within the fixing grooves 110 according to the different thicknesses of the bearing inner rings to be processed, ensuring that the first primary screening stage 302 can stack the bearing inner rings to be processed in a maximum of three layers in the axial direction, the second primary screening stage 303 can stack the bearing inner rings to be processed in a maximum of two layers in the axial direction, and the third primary screening stage 304 can distribute the bearing inner rings to be processed in a single layer in the axial direction. The first primary screening stage 302 is equipped with an anti-overflow front baffle 301 to ensure that the bearing inner rings to be processed are not squeezed to the upper part of the third primary screening mechanism during the screening process.

[0036] Furthermore, such as Figure 2 , 3 As shown, the primary screening conveyor belt section 1 is at a 135-degree angle to the feeding conveyor belt section 6 on the horizontal plane, with an allowable installation error of ±2 degrees. It includes the primary screening conveyor belt body 106, which is driven by the primary screening conveyor belt drive motor 101 mounted on the primary screening drive bearing plate 102 through a two-stage reduction of the primary screening conveyor belt drive belt 104 and the primary screening conveyor belt drive pulley 103. Its running direction is to transport the inner ring of the bearing to be processed on the primary screening conveyor belt section 1 to the inclined conveyor belt section 4. Furthermore, the primary screening conveyor belt section 1 is equipped with a primary screening conveyor belt baffle 105, a heightened front baffle 107, and a heightened rear baffle 108 on both sides.

[0037] Furthermore, such as Figure 5As shown, the inclined conveyor belt section 4 is at a 60-degree angle to the horizontal plane, with an allowable installation error of ±2 degrees. It includes an inclined conveyor belt body 401. The inclined conveyor belt body 401 is driven forward by a feeding conveyor belt drive motor 606 mounted on the feeding drive support plate 605 in the feeding conveyor belt section 6. This motor, after two reductions via the feeding conveyor belt drive belt 603 and feeding conveyor belt drive pulley 604, simultaneously drives the inclined conveyor belt drive shaft 404 to rotate. This is achieved through a pair of inclined conveyor belt drive bevel gears 601 and the inclined conveyor belt drive belt 405 mounted next to the right baffle 610 of the feeding conveyor belt and on the inclined conveyor belt drive support plate 602. The inclined conveyor belt body 401 travels in the direction of transporting the inner rings of the bearings to be processed on the inclined conveyor belt section 4 to the feeding conveyor belt. In section 6, the inclined conveyor belt body 401 has a right baffle 406 on the right side, a left baffle 402 on the left side, and a transition baffle 403 below. The upper end of the transition baffle 403 is fixed to the right baffle 406 and the left baffle 402, and the lower end is fixed to the right baffle 610 of the loading conveyor belt section 6. The transition baffle 403 ensures that the inner ring of the bearing to be processed on the inclined conveyor belt body 401 can smoothly enter the loading conveyor belt section 6. The inclined conveyor belt body 401 has strip-shaped protrusions parallel to the working direction, which can provide support for the correction work of the correction conveyor belt section 5 and ensure that the inner ring of the bearing to be processed will not slip on the inclined conveyor belt body 401 when being corrected.

[0038] Furthermore, such as Figure 6 , 7 As shown in Figure 8, the correction conveyor belt section 5 includes a correction conveyor belt body 502. The correction conveyor belt body 502 is driven by a correction conveyor belt drive motor 508 fixed on the correction conveyor belt drive support plate 507, which is decelerated by the correction conveyor belt drive belt 506 and the correction conveyor belt drive pulley 505. Its working direction is to move backward toward the inclined conveyor belt section 4. The correction conveyor belt body 502 has an upper correction conveyor belt baffle 504 on its upper side and a lower correction conveyor belt baffle 503 on its lower side. A correction conveyor belt transition baffle 513 is installed below the lower correction conveyor belt baffle 503. A correction conveyor belt transition baffle extension baffle 514 is installed in front of the correction conveyor belt transition baffle 513.

[0039] Furthermore, the lower baffle 503 of the correction conveyor belt is connected to the bearing plate 511 of the correction conveyor belt on both sides by two sets of double slider guide rails 501 and heightening blocks 512, and a correction conveyor belt screw slide 510 is connected to the bearing plate 511 in the middle. The correction conveyor belt screw slide 510 is driven by a handwheel 509. When changing the batch thickness of the inner ring of the bearing to be processed, the position of the correction conveyor belt section 5 needs to be adjusted by the handwheel 509 so that the distance between the transition baffle 513 of the correction conveyor belt and the transition baffle 403 of the inclined conveyor belt is slightly larger than the thickness of the inner ring of the bearing to be processed. This ensures that the correction conveyor belt body 502 can successfully correct the inner ring of the bearing to be processed whose end face does not contact the inclined conveyor belt body 401, so that the inner ring of the bearing to be processed falling into the loading conveyor belt section 6 has its end face parallel to the right baffle 610 of the loading conveyor belt and has no axial overlap.

[0040] Furthermore, such as Figure 5 As shown, the feeding conveyor belt section 6 includes a feeding conveyor belt body 608. The feeding conveyor belt body 608 is driven by a feeding conveyor belt drive motor 606 mounted on the feeding drive load-bearing plate 605, which reduces speed twice via the feeding conveyor belt drive belt 603 and the feeding conveyor belt drive pulley 604. The direction of movement is to transport the inner ring of the bearing to be processed forward (i.e., towards the triangular loading and unloading integrated mechanism section 9). The left side of the feeding conveyor belt body 608 is a left baffle 607, and the right side is a right baffle 610. The right baffle 610 has a rectangular feeding groove 609, which allows the triangular loading and unloading integrated mechanism section 9 to complete the feeding smoothly. The feeding conveyor belt body 608 has evenly distributed barbed protrusions, which ensures that the inner ring of the bearing to be processed on the feeding conveyor belt body 608 is arranged in an orderly manner at certain intervals according to the distribution of the barbed protrusions.

[0041] Furthermore, such as Figure 9 , 10 As shown, the inclined conveyor belt transition baffle 403 and the correction conveyor belt transition baffle 513 are equipped with an exit baffle first section 611 at the front end, and an exit baffle second section 612 is installed on the inclined conveyor belt right baffle 406. The position of the exit baffle first section 611 is just enough to allow the inner ring of the bearing to be processed on the feeding conveyor belt body 608 to pass through individually without radial overlap, while the exit baffle second section 612 can prevent the inner ring of the bearing to be processed from passing over the exit baffle first section 611. The positions of the exit baffle first section 611 and the exit baffle second section 612 can be appropriately adjusted according to the different sizes of the inner ring of the bearing to be processed through their screw grooves. When the actual need exceeds the adjustable range, the exit baffle first section 611 and the exit baffle second section 612 of appropriate size can be replaced.

[0042] Furthermore, such as Figure 11 As shown, the triangular loading and unloading integrated mechanism 9 includes a triangular loading and unloading tray 901. Annular electromagnets 902 are respectively installed at the three corners of the triangular loading and unloading tray 901. Each annular electromagnet 902 contains three electromagnet rings with different diameters: a first electromagnet ring 910, a second electromagnet ring 911, and a third electromagnet ring 912. The triangular loading and unloading tray 901 is driven by a triangular loading and unloading tray drive motor 905, and the annular electromagnets 902 are powered by a power supply control device 903. The triangular loading and unloading tray drive motor 905 is installed... The triangular loading and unloading tray drive motor bracket 904 and the power supply control device 903 are mounted on the triangular loading and unloading integrated mechanism load plate 909. The triangular loading and unloading integrated mechanism load plate 909 is mounted on the triangular loading and unloading integrated mechanism moving platform 908. The triangular loading and unloading integrated mechanism moving platform 908 is controlled by the triangular loading and unloading integrated mechanism moving control motor 906. The triangular loading and unloading integrated mechanism moving control motor 906 is fixed by the triangular loading and unloading integrated mechanism moving control motor bracket 907. The sizes of the first electromagnet ring 910, the second electromagnet ring 911, and the third electromagnet ring 912 decrease from large to small. Different sizes of electromagnet rings can be selected according to the different radial dimensions of the inner rings of the bearings to be processed in batches. The triangular loading and unloading tray 901 is driven to rotate by the triangular loading and unloading tray drive motor 905, and the power supply control device 903 supplies power to the annular electromagnet 902, and controls the type of electromagnet ring used and when the electromagnet ring has attraction. The triangular loading and unloading tray drive motor 905 is mounted on the triangular loading and unloading tray drive motor bracket 904 to ensure stability. The triangular loading and unloading tray drive motor bracket 904 and the power supply control device 903 are mounted on the triangular loading and unloading integrated mechanism load plate 909. The load plate is mounted on the triangular loading and unloading integrated mechanism moving table 908. The moving table is controlled by the triangular loading and unloading integrated mechanism moving control motor 906, so that the triangular loading and unloading tray 901 can make linear movements away from and towards the loading conveyor belt section 6.

[0043] Furthermore, such as Figure 12As shown, the machining fixture part 8 includes a fixture support 801, a fixture base 802, and an electromagnetic adsorption ring 804, a side top block 806, and a bottom top block 803 mounted on the fixture base 802; a roller 805 is respectively mounted on the side top block 806 and the bottom top block 803, and the fixture base 802 is mounted on the fixture support 801. The machining fixture part 8 consists of an electromagnetic adsorption ring 804 as the main body, and a side top block 806 and a bottom top block 803 as auxiliary components. They are mounted on the fixture base 802. Each of the side top block 806 and the bottom top block 803 has a roller 805. During machining, the electromagnetic adsorption ring 804 adsorbs the inner ring of the bearing to be machined. The side top block 806 and the bottom top block 803 hold the inner ring of the bearing to be machined against the surface to be machined through the roller 805, thereby overcoming the radial force during machining. At the same time, as machining progresses, the surface to be machined gradually becomes the machined surface. The roller 805 in contact with it can greatly reduce the friction on the machined surface, thereby ensuring the quality of the machined surface.

[0044] Furthermore, such as Figure 1 As shown, the unloading guide rail 10 is installed below the loading conveyor belt section 6, receiving the processed bearing inner rings transported by the integrated loading and unloading mechanism section 9, and guiding the processed bearing inner rings into the unloading box 11. Because this invention adopts a design that allows for simultaneous loading and unloading, the design ensures that the end faces of the bearing inner rings to be processed on the loading conveyor belt body 608 are parallel to the right baffle of the loading conveyor belt, and that the bearing inner rings to be processed, which are arranged neatly at a certain interval without axial or radial overlap, are all in the same plane as the bearing inner rings to be processed correctly clamped on the processing fixture section 8 and the processed bearing inner rings on the unloading guide rail 10.

[0045] Furthermore, the inclined conveyor belt body 401 has strip-shaped protrusions parallel to the working direction; the correction conveyor belt body 502 has strip-shaped protrusions perpendicular to the working direction, which can provide sufficient correction force to correct the inner ring of the bearing to be processed, whose upper end face of the inclined conveyor belt section 4 is not in contact with the inclined conveyor belt body 401, to the correct state where the end face is in contact with the inclined conveyor belt body 401; the feeding conveyor belt body 608 has barbed protrusions evenly distributed.

[0046] The working process of this invention:

[0047] like Figure 2As shown, a basket of bearing inner rings 2 to be processed can be randomly poured into the beginning of the primary screening conveyor belt section 1 by manual labor or machine, as shown in state 201. After being conveyed by the primary screening conveyor belt body 106 and passing through the multi-stage primary screening mechanism section 3, the originally messy bearing inner rings to be processed are transformed into a flat state with only one layer and the end face in contact with the primary screening conveyor belt body 106, as shown in state 202. The primary screening conveyor belt body 106 continues to convey the bearing inner rings to be processed to the inclined conveyor belt section 4. When the inner ring of the bearing to be processed falls into the inclined conveyor belt 401, if all goes smoothly, its end face should be in contact with the inclined conveyor belt 401 and laid flat on the inclined conveyor belt, as shown in 203. If the end face of the inner ring of the bearing to be processed does not contact the inclined conveyor belt 401 but falls in a rolling manner, as shown in 204, then when it rolls down and contacts the correction conveyor belt 502, it will be corrected to the correct state by the strip-shaped protrusions on the correction conveyor belt 502 working together with the strip-shaped protrusions on the inclined conveyor belt 401. Here, the working direction of the correction conveyor belt 502 is towards the inclined belt. The conveyor belt moves backward on one side. This working direction ensures that the incorrect position of the inner ring of the bearing to be processed is corrected smoothly, and at the same time, the inner ring of the bearing to be processed is moved slightly backward. This ensures that there will be no transitional congestion of the inner ring of the bearing to be processed at the first section 611 and the second section 612 of the outlet baffle. After the correction of the correction conveyor belt section 5, and under the joint constraint of the inclined conveyor belt transition baffle 403 and the correction conveyor belt transition baffle 513, the inner rings of the bearings to be processed falling into the feeding conveyor belt body 608 are all in a state where the end face is parallel to the right baffle 610 of the feeding conveyor belt and there is no axial overlap, as shown in 205. Driven by the feeding conveyor belt 608, the inner ring of the bearing to be processed is transported forward. When it reaches the first section 611 and the second section 612 of the exit baffle, their joint obstruction causes the inner ring of the bearing to be processed, which originally overlapped radially as shown in 206, to be flattened. After passing through the first section 611 and the second section 612 of the exit baffle, the inner ring of the bearing to be processed becomes a state in which the end face is parallel to the right baffle 610 of the feeding conveyor belt, with no overlap in the axial and radial directions, and is neatly arranged at a certain interval according to the barbed protrusions on the feeding conveyor belt 608, as shown in 207.The extension baffle 514 of the transition baffle 513 installed in front of the transition baffle 514 of the straightening conveyor belt ensures that the inner ring of the bearing to be processed on the feeding conveyor belt will not tip over during transportation to the rectangular feeding trough. When the inner ring of the bearing to be processed is transported to the feeding trough 609, the triangular loading and unloading mechanism 9 is responsible for loading and unloading. During loading and unloading, when the annular electromagnet 902 located at the feeding trough 609 of the feeding conveyor belt 6 uses an electromagnet ring of appropriate size to attract the inner ring of the bearing to be processed, and at the same time, the annular electromagnet 902 located at the processing fixture 8 uses an electromagnet ring of appropriate size to attract the inner ring of the processed bearing, the triangular loading and unloading mechanism 9... The material tray 901 needs to be moved away from the loading conveyor belt 6 and the processing fixture 8 by the triangular loading and unloading integrated mechanism moving control motor 906. After moving away from the material tray 901 by a distance exceeding the thickness of the inner ring of the bearing to be processed, the moving motion stops. At this time, the triangular loading and unloading tray drive motor 905 works, driving the triangular loading and unloading tray 901 to rotate. This causes the inner ring of the bearing to be processed, which is attracted by the annular electromagnet 902 located at the loading groove 609, to move to the processing fixture 8. At this time, the annular electromagnet 902, which was originally at the processing fixture 8, has attracted the inner ring of the bearing to be processed and transported it to the unloading guide rail 10. At this point, the triangular loading / unloading tray 901, controlled by the triangular loading / unloading integrated mechanism movement control motor 906, moves the triangular loading / unloading integrated mechanism moving table 908 closer to the loading conveyor belt section 6, the processing fixture section 8, and the unloading guide rail 10. When the triangular loading / unloading tray 901 moves back to its previous position, the annular electromagnet 902 at the processing fixture section 8 and the unloading guide rail 10 respectively releases the inner ring of the bearing to be processed and the inner ring of the already processed bearing. The inner ring of the bearing to be processed at the processing fixture section 8 is attracted by the electromagnetic attraction ring 804 of the processing fixture section 8 to complete the loading. At the same time, the inner ring of the already processed bearing at the unloading guide rail 10 rolls along the unloading guide rail 10 into the unloading box 11 to complete the loading. Next, the triangular loading and unloading tray 901, through the triangular loading and unloading integrated mechanism movement control motor 906, controls the triangular loading and unloading integrated mechanism moving table 908 to move it away from the loading conveyor belt section 6 again until the position where the previous movement ended. The inner ring of the bearing to be processed at the processing fixture section 8 is completed. The triangular loading and unloading tray 901, through the triangular loading and unloading integrated mechanism movement control motor 906, controls the triangular loading and unloading integrated mechanism moving table 908 to move it closer to the loading conveyor belt section 6 until the position before it moved away is reached. This completes one loading and unloading process cycle, and the next loading and unloading cycle begins until all the inner rings of the bearings to be processed are processed.

[0048] If the radial or thickness dimensions of the inner ring of the bearing to be processed change, the position of each stage of the multi-stage primary screening mechanism 3 can be adjusted through the pre-reserved fixing grooves 110 on the raised back baffles 108 on both sides of the primary screening conveyor belt 1; the position of the correction conveyor belt 5 can be adjusted through the handwheel 509 of the correction conveyor belt 5; the positions of the first section 611 and the second section 612 of the outlet baffle can be adjusted appropriately through the screw grooves, or the first section 611 and the second section 612 of the outlet baffle can be replaced with outlet baffles of appropriate size; the power supply control device 903 of the triangular loading and unloading integrated mechanism 9 can be used to make the annular electromagnet 902 use an electromagnet ring of appropriate size to attract the inner ring of the bearing to be processed and the inner ring of the processed bearing, so that the whole device can adapt to the new bearing inner ring batch with the new radial and thickness dimensions.

[0049] Applying the above technical solution, the three-stage primary screening mechanism is partially installed on the primary screening conveyor belt. In conjunction with the inclined conveyor belt, the correction conveyor belt, and the feeding conveyor belt, along with the outlet baffle on the feeding conveyor belt, a batch of bearing inner rings to be processed, randomly poured into the beginning of the primary screening conveyor belt, is transformed at the outlet of the feeding conveyor belt into a state where the end face is parallel to the right baffle of the feeding conveyor belt, with no overlap in the radial and axial directions. The triangular loading and unloading integrated mechanism utilizes its annular electromagnets mounted at the three corners to achieve simultaneous loading and unloading. The processing fixture uses top blocks with rollers, ensuring reliable clamping while significantly reducing wear on the processed surface. The unloading guide rail and unloading box collect the processed bearing inner rings transported by the triangular loading and unloading integrated mechanism. This invention has a high degree of automation, greatly reducing labor costs. Simultaneous loading and unloading effectively improves production efficiency, and the improved processing fixture ensures the quality of the processed workpiece surface.

However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
