Description

Technical Field

[0001] The present invention relates to the technical field of bearing processing, and specifically to a positioning tooling assembly and process for bearing processing. Background Art

[0002] A bearing is an important component in contemporary mechanical equipment. Its main function is to support the mechanical rotating body, reduce the friction coefficient during its movement, and ensure its rotation accuracy.

[0003] According to the different friction properties of the moving elements, bearings can be divided into two categories: rolling bearings and sliding bearings. During the bearing processing, arc grooves need to be opened on the inner ring and outer ring of the bearing components. In the traditional method, different positioning clamps need to be adopted according to the processing positions for processing. However, in practice, when mass-producing bearings, using different positioning clamps for bearing components not only requires more workstations but also prolongs the bearing processing time.

Detailed implementation manners

[0035] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0036] Embodiment 1

[0037] Provide a positioning tooling assembly for bearing processing, including a stand 100, a turntable 200, a carrier board 300 and a positioning mechanism.

[0038] Please refer to Figure 1 , above the stand 100, there is a material pipe 100. The stand 100 has a processing station. The material pipe 100 is used to accommodate the bearing parts to be processed, and the bearing parts can fall vertically along the material pipe 100.

[0039] Please refer to Figure 1 , Figure 2, The turntable 200 is rotatably arranged on the gantry 100. A number of material receiving areas 210 are arranged on the turntable 200. The turntable 200 is connected with a motion component 400, which can drive the turntable 200 to rotate to sequentially guide the bearing components in the material to fall into the material receiving areas 210 and move to the processing station. That is, the motion component 400 can drive the turntable 200 to rotate so that the material receiving areas 210 thereon are aligned with the material pipe 100, the discharge end of the material pipe 100 is unobstructed, and the bearing components can smoothly fall and enter the feeding area. Thus, the bearing components are driven by the rotation of the turntable 200 to move to the processing station;

[0040] Please refer to Figure 1 , Figure 2 , The carrier plate 300 is located at the processing station and is used to carry the bearing components. The carrier plate 300 is rotatably connected to the gantry 100, and the upper surface of the carrier plate 300 is flush with the upper surface of the gantry 100, so that the bearing components can smoothly move onto the carrier plate 300 for processing when driven by the turntable 200, and can leave the carrier plate 300 when driven by the turntable 200 after processing.

[0041] Please refer to Figure 1 , Figure 2 , The positioning mechanism includes an adjustment component 500 and a power component 600 arranged on the carrier plate 300. The adjustment component 500 is used to adjust the bearing components to be in the same position on the carrier plate 300 each time and keep them fixed. The power component 600 is power-connected to the carrier plate 300 to rotate the bearing components fixed on the carrier plate 300 for simultaneous processing of the inner and outer rings. That is, the bearing components are in the same position each time and can rotate. During processing, different tool heads can contact the inner and outer rings of the bearing components under the drive of an external driving device, and the movement stroke of the tool heads is fixed. That is to say, the consistency and processing accuracy of processing the bearing components are ensured, the processing time is shortened, and there is no need for manual transfer and loading and unloading of materials.

[0042] Embodiment 2

Please refer to Figure 3, a convex edge 120 is provided on the outside of the rack 100, a guide groove 220 is formed on the return disk 200, and the groove and the convex edge 120 form a channel. The channel communicates with the tops of a number of feeding areas. The material pipe 100 is vertically butted against the channel, so that the bearing parts to fall are partially exposed from the material pipe 100, and are laterally limited at the upper and lower ends by the material pipe 100 and the channel, realizing direct observation of the state of the bearing parts to fall. Thus, during the large-batch processing of bearing parts, once it is found that the bearing parts are not exposed from the bottom of the material pipe 100 in time, it indicates that the number of bearing parts in the material pipe 100 is insufficient or there is a problem with the falling of the bearing parts in the material pipe 100, which is convenient for timely replenishing the bearing parts or timely detecting, inspecting and checking. At the same time, the exposed bearing parts are in contact with the channel, the bottom is limited by the channel, and the top is limited by the material pipe 100. When the return disk 200 rotates, the exposed bearing parts have good stability and are not easily deflected when falling into the feeding area.

[0044] Please refer to Figure 4 , the motion assembly 400 includes a first motor 410 installed on the rack 100 and a shaft rod 420 connected to the return disk 200. The shaft rod 420 passes downward through the rack 100 and is connected with a driven gear 421. The output end of the first motor 410 is connected with a driving gear 411, and the driving gear 411 meshes with the driven gear 421.

[0045] Please refer to Figure 4 , the material receiving area 210 is laterally open, a notch is formed at both ends of the convex edge 120, the driving gear 411 is connected with a rotating shaft 430 passing upward through the rack 100, the top of the rotating shaft 430 is connected with a lining frame 431, a push rod 440 is hinged on the upper side of the rack 100, the lining plate is movably connected with the push rod 440 through a movable rod 450, and the first motor 410 drives the return disk 200 to rotate intermittently through the meshing of the driving gear 411 and the driven gear 421, and drives the lining frame 431 to rotate with the rotating shaft 430, so that the movable rod 450 drives the push rod 440 to reciprocate to push the processed bearing parts out of the material receiving area 210. That is, while the first motor 410 drives the return disk 200 to drive the bearing parts to feed on the rack 100, it can drive the push rod 440 to reciprocate to push the processed bearing parts out from the notch, realizing automatic discharging of the bearing parts.

[0046] Embodiment 3

[0047] Provide a positioning tooling assembly for bearing processing, please refer to Figure 5 , Figure 6, the adjusting assembly 500 includes a recessed area formed on the carrier plate 300. A lifting rod 510 is movably inserted through the recessed area, and the lifting rod 510 can move up and down relative to the recessed area. A backing plate 520 is fixedly connected to the top of the lifting rod 510. Two contact sections 530 are provided on the inner circle of the recessed area. The contact sections 530 extend in an arc shape and gradually expand outward, and the two contact sections 530 are connected end to end, forming a retaining platform 531 at the connection of the head and the tail. Two groups of moving plates 521 are slidably arranged on the backing plate 520. One end of each group of moving plates 521 is connected to the backing plate 520 through an elastic member 522. A resisting block 523 is arranged on the upper side of each group of moving plates 521. The elastic member 522 includes a telescopic rod and a spring wound around the telescopic rod. When the bearing component moves to the carrier plate 300 at the processing station, the two ends of the two groups of moving plates 521 that are far away from each other respectively contact a contact section 530. Thus, the elastic member 522 is compressed to make the two resisting blocks 523 approach each other.

[0048] Preferably, please refer to Figure 5 , Figure 6 , a plurality of discharge holes are provided on both the gantry 100 and the recessed area, so that part of the debris generated at the processing station can be directly discharged through the discharge holes, and the other part can be pushed out through the discharge holes under the action of the movement of the bearing component on the turntable 200.

[0049] Please refer to Figure 7 , the power assembly 600 includes a second motor 610 installed on the gantry 100. The adjusting assembly 500 further includes a first electric cylinder 540 installed on the gantry 100. The movable end of the first electric cylinder 540 is rotatably connected to the lifting rod 510 through a bushing 511. The second motor 610 is drivingly connected to the carrier plate 300. Preferably, the second motor 610 drives the carrier plate 300 through a pulley group. The first electric cylinder 540 drives the lifting rod 510 to drive the two resisting blocks 523 to move upward out of the recessed area. The second motor 610 drives the carrier plate 300 to rotate forward. The moving plates 521 move relative to the contact sections 530 to the retaining platform 531 through the elastic members 522, so that the two resisting blocks 523 extend outward to push the bearing component to move to a fixed position and press tightly against the bearing component. It should be noted that the two groups of moving plates 521 are symmetrically distributed with respect to a central plane of this fixed position. That is, the two resisting blocks 523 move upward away from the recessed area under the drive of the first electric cylinder 540, and then move away from each other, so that the bearing component moving to the carrier plate 300 is pushed by the two resisting blocks 523 to move to the fixed position.

[0050] Please refer to Figure 7 , after the bearing component moves to the fixed position, the second motor 610 drives the carrier plate 300 to rotate forward again, so that the carrier plate 300 drives the bearing component to rotate. At this time, the two ends of the two moving plates 521 that are far away from each other are respectively pushed by the retaining platform 531 and can rotate simultaneously with the bearing component. That is to say, the two resisting blocks 523 also rotate synchronously during this process and press against the bearing component.

[0051] Please refer to Figure 7 and Figure 8 Figure 8

[0052] After the bearing component is processed, the second electric cylinder 550 drives the ring plate 560 to reset upward, the second motor 610 drives the carrier plate 300 to reverse, so that the moving plate 521 moves away from the contact section 530 relative to the stop block 531, bringing the two abutting blocks 523 closer together. The first electric cylinder 540 drives the lifting rod 510 to drive the two abutting blocks 523 to move downward out of the concave area, and the first motor 410 drives the turntable 200 to rotate, taking the processed bearing component away from the carrier plate 300.
