DETAILED DESCRIPTION

[0028] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0029] like Figures 1-8The processing device of a special-shaped bearing outer ring part shown in the figure includes a processing workbench 1, a stationary seat 2, and a rotating seat 3. The stationary seat 2 is fixedly installed on the table of the processing workbench 1. The stationary seat 2 is used as a functional platform and can be installed with auxiliary devices. The rotating seat 3 is rotatably sleeved on the outside of the stationary seat 2. Along the rotation direction of the rotating seat 3, there are successively provided with a loading station 31, a primary processing station 32, a secondary processing station 33 and a discharge station 34. The outer edge of the rotating seat 3 is connected to the outer edge of the rotating seat 3 and is installed with an outer ring clamp 4. The outer ring clamp 4 can install a bearing outer ring workpiece. The outer ring clamp 4 and the bearing outer ring workpiece rotate with the rotating seat 3 and flow through the loading station 31, the primary processing station 32, the secondary processing station 33 and the discharge station 34. The loading station 31 A loading robot 5 is installed correspondingly, and the loading robot 5 can automatically grab the bearing outer ring workpiece and install it in the outer ring clamp 4. The primary processing station 32 is correspondingly installed with a primary processing device 6, and the primary processing device 6 can form the first groove on the bearing outer ring workpiece. The secondary processing station 33 is correspondingly installed with a secondary processing device 7, and the secondary processing device 7 can form the second groove on the bearing outer ring workpiece. The discharging station 34 is correspondingly installed with an output slide 341 and a discharging device 8. The bearing outer ring workpiece that has been processed twice is already a finished product. At the discharging station 34, it is pushed out of the outer ring clamp 4 by the discharging device 8, and then slides down the output slide 341 for output. The discharging device 8 is installed on the stationary seat 2, as shown Figure 9 and Figure 10 As shown in the figure, there are two grooves on the bearing outer ring workpiece, one on the outer wall of the bearing ring and the other on the side end face of the bearing ring. Therefore, the bearing outer ring workpiece needs to be placed in a different position during the processing. When the bearing outer ring workpiece is placed vertically, the outer wall groove can be processed. When the bearing outer ring workpiece is placed horizontally, the side end face groove can be processed. Figure 1As shown, the present invention is provided with a retaining rod groove 11 and a horizontal retaining frame 12 on the surface of the processing workbench 1, and the outer ring clamp 4 includes an outer ring clamp 42 which is flipped and installed. The outer ring clamp 42 can clamp the outer ring workpiece of the bearing, and the bottom of the outer ring clamp 42 is connected with an upright retaining rod 421. When the upright retaining rod 421 is inserted into the retaining rod groove 11, the outer ring clamp 42 remains in an upright state. Both assembly and one-time processing require the outer ring clamp 42 to remain in an upright state. Therefore, the retaining rod groove 11 is set corresponding to the movement stroke of the outer ring clamp 4 from the assembly station 31 to the one-time processing station 32. During this stroke of the outer ring clamp 4, the upright retaining rod 42 1 is always in the retaining rod groove 11, and the outer ring clamp 42 is always kept in an upright state. Both secondary processing and discharge require the outer ring clamp 42 to remain in a horizontal state. Therefore, the horizontal retainer 12 is set corresponding to the movement stroke of the outer ring clamp 4 from the secondary processing station 33 to the discharge station 34. The outer ring clamp 42 can be flipped and laid down on the horizontal retainer 12. The horizontal retainer 12 can keep the outer ring clamp 42 in a horizontal state. The present invention uses the rotary seat 3 to circulate the bearing outer ring workpiece, and automatically completes the operations of clamping, primary processing, secondary processing, and discharge of the bearing outer ring workpiece during the circulation. The present invention has the advantages of high degree of automation and high production efficiency.

[0030] like Figure 2 As shown, the outer wall of the rotary seat 3 is connected to a transmission ring gear 35, and the processing workbench 1 is installed with a rotary power assembly 36. The rotary power assembly 36 includes a motor 361 and a driving gear 362. The driving gear 362 is connected to the output end of the motor 361. The driving gear 362 is meshed with the transmission ring gear 35. The motor 361 can drive the driving gear 362 to rotate. The motor 361 drives the rotary seat 3 to rotate through the meshing relationship between the driving gear 362 and the transmission ring gear 35. Figure 1 As shown, there are four outer ring clamps 4 installed, and the four outer ring clamps 4 are evenly connected to the outer edge of the rotary seat 3. The four outer ring clamps 4 correspond to the assembly station 31, the primary processing station 32, the secondary processing station 33 and the discharge station 34 respectively. Each time the motor 361 is started, it drives the rotary seat 3 to rotate ninety degrees, and each time there is an outer ring clamp 4 that falls on the corresponding station. In this way, as the rotary seat 3 rotates, the processing and production of the bearing outer ring workpiece can be continued.

[0031] like Figure 3 As shown, the outer ring clamp 4 also includes a plate seat 41, two plate seats 41 are symmetrically installed, and two shaft heads 4221 are symmetrically connected on both sides of the outer ring clamp 42. The outer ring clamp 42 is flipped and installed on the two plate seats 41 through the shaft heads 4221. The bearing outer ring workpiece is clamped in the outer ring clamp 42. The switching between the upright state and the horizontal state is achieved by flipping the outer ring clamp 42. Figure 4 and Figure 5As shown, the outer ring fixture 42 includes a fixture body 422, a V-shaped positioning block 423, and a clamping plate 424. The V-shaped positioning block 423 is fixedly connected to the fixture body 422. The V-shaped positioning block 423 has a groove, which can stably position the bearing outer ring workpiece. A clamping release cylinder 425 is installed on the side of the fixture body 422. The clamping plate 424 is connected to the piston rod end of the clamping release cylinder 425. The extension and retraction of the piston rod of the clamping release cylinder 425 can make the clamping plate 424 move away from or close to the V-shaped positioning block 423. There are two clamping release cylinders 425, which are symmetrically installed and extend and retract synchronously. When the clamping plate 424 is away from the V-shaped positioning block 423, the outer ring can be clamped. The opening effect of the clamp 42 allows for unloading and loading operations. The open state of the outer ring clamp 42 appears at the loading station 31 and the unloading station 34. When the clamping plate 424 is close to the V-shaped positioning block 423, the clamping state of the outer ring clamp 42 can be achieved. The bearing outer ring workpiece is positioned and clamped in the outer ring clamp 42. In the primary processing station 32 and the secondary processing station 33, the outer ring clamp 42 must remain clamped. In the present invention, the thickness of the V-shaped positioning block 423 must be less than the thickness of the bearing outer ring workpiece. Only when the clamping plate 424 is close to the V-shaped positioning block 423 can a clamping effect be formed on the bearing outer ring workpiece on the V-shaped positioning block 423.

[0032] like Figure 1As shown, the retaining rod groove 11 is arc-shaped. When the retaining rod groove 11 matches the outer ring clamp 42 in the upright state, the movement path of the upright retaining rod 421, the retaining rod groove 11 does not affect the rotation of the swivel seat 3, the retaining rod groove 11 only plays the role of maintaining the outer ring clamp 42 in the upright state, and when the swivel seat 3 rotates, the upright retaining rod 421 can slide along the arc length direction of the retaining rod groove 11, and the retaining rod groove 11 is provided with an outlet end 111 and an inlet end 112. The outlet end 111 extends toward the secondary processing station 33 after passing the primary processing station 32. During the first groove processing, the outer ring workpiece of the bearing needs to be kept upright, so the outer ring clamp 42 of the primary processing station 32 also needs to be kept upright, which requires the retaining rod groove 11 to cover the stroke of the primary processing station 32. Therefore, the outlet end 111 of the retaining rod groove 11 needs to pass through the primary processing station 32, and the inlet end 112 passes through the assembly station After passing the processing station 32 once, the outer ring clamp 42 and the bearing outer ring workpiece need to be switched to a horizontal state. Therefore, the present invention installs a flip drive vertical plate 13 on the table top of the processing workbench 1, one end of the flip drive vertical plate 13 is connected to the outlet end 111 of the retaining rod groove 11, and the other end of the flip drive vertical plate 13 extends in an arc toward the outer edge of the swivel seat 3, and the upright holding rod 421 slides out of the outlet end 111 of the retaining rod groove 11 and contacts the flip drive vertical plate 13. Figure 1 As shown, since the arc of the flip driving vertical plate 13 is different from the retaining rod groove 11, its outer end extends close to the outer edge of the rotary seat 3, so it can form a toggle effect on the upright retaining rod 421, and the flip driving vertical plate 13 can cause the outer ring clamp 42 to flip (clockwise flip). The horizontal retaining frame 12 includes a horizontal operating table 121 and a guide arc plate 122. The horizontal operating table 121 and the guide arc plate 122 are of the same height. The two horizontal operating tables 121 are respectively arranged at the secondary processing station 33 and the discharge station 34. The guide arc plate 122 is connected to the horizontal On the side of the operating table 121, a section of the guide arc plate 122 extends toward the outlet end 111 of the retaining rod groove 11. After the flip driving vertical plate 13 causes the outer ring clamp 42 to flip, the fallen outer ring clamp 42 contacts the guide arc plate 122 to form a horizontal state. The other section of the guide arc plate 122 extends toward the inlet end 112 of the retaining rod groove 11. The guide arc plate 122 can ensure that the outer ring clamp 42 can perform rotational motion in a horizontal state. The two horizontal operating tables 121 are large platforms, which play a role in work support and can facilitate the completion of secondary groove processing and discharging operations.

[0033] The outer ring clamp 42 completes the discharge operation in a horizontal state, but needs to be reset to an upright state after discharging so that a new bearing outer ring workpiece can be added. Therefore, the present invention also designs a flip reset component 43 on the outer ring clamp 4, and the flip reset component 43 includes a shaft frame 431 and a rotating shaft 432. The shaft frame 431 is fixedly installed on the plate base 41, and the rotating shaft 432 is rotatably installed on the shaft frame 431. One end of the rotating shaft 432 is connected to a gear column 433, and the other end is connected to a first transmission gear 434. One of the outer ring clamps 42 The shaft head 4221 extends outward and is connected to the second transmission gear 435. The first transmission gear 434 and the second transmission gear 435 are bevel gears. The first transmission gear 434 and the second transmission gear 435 are meshed with each other. The gear column 433, the rotating shaft 432, the first transmission gear 434 and the second transmission gear 435 form a series of transmission effects, which can drive the outer ring clamp 42 to flip. A reset drive gear plate 436 is fixedly installed on the top plane of the stationary seat 2. The reset drive gear plate 436 is arranged on the movement trajectory of the gear column 433. On the line, during the rotational movement of the outer ring clamp 4, the flip reset component 43 will only take effect when the flip reset component 43 moves to the reset drive tooth plate 436 position (the flip reset component 43 does not play a substantial role in other stroke positions). When the flip reset component 43 moves to the reset drive tooth plate 436, the reset drive tooth plate 436 and the gear column 433 can form a meshing engagement, and the meshing transmission of the reset drive tooth plate 436 and the gear column 433 can drive the gear column 433, the rotating shaft 432, and the first transmission gear A series of movements of the wheel 434 and the second transmission gear 435 eventually switch the outer ring clamp 42 from a horizontal state to an upright state. The meshing transmission of the reset drive gear plate 436 and the gear column 433 is set in the movement stroke of the outer ring clamp 4 from the discharge station 34 to the loading station 31. After the outer ring clamp 42 is flipped and upright, the upright retaining rod 421 at its lower end just enters the entrance end 112 of the retaining rod groove 11. The entrance end 112 of the retaining rod groove 11 is set as a trumpet mouth, which can ensure that the upright retaining rod 421 slides in smoothly.

[0034] like Figure 5 As shown, the bottom of the V-shaped positioning block 423 is provided with two discharge holes 426, as shown in FIG. Figure 1As shown, the discharging device 8 includes a discharging push cylinder 81 and a discharging ejector rod 82. The discharging push cylinder 81 is fixedly installed on the top plane of the stationary seat 2. Two discharging ejector rods 82 are connected to the piston rod end of the discharging push cylinder 81. The size of the discharging ejector rod 82 matches the discharging through hole 426. The discharging ejector rod 82 is installed opposite the discharging station 34. After the outer ring clamp 42 falls on the discharging station 34, the outer ring clamp 42 is automatically released from the clamping. The discharging ejector rod 82 is pushed by the piston rod of the discharging push cylinder 81 to move toward the outer ring clamp 42 and is inserted into the outer ring clamp 42 through the discharging through hole 426 to push out the processed bearing outer ring workpiece. The output slide 341 is installed at an angle, and the high point of the output slide 341 extends to the discharging station 34. The pushed-out bearing outer ring workpiece just falls into the output slide 341 and slides out naturally.

[0035] The first processing of the bearing outer ring workpiece is to process the groove on the outer wall of the ring and punch the groove position, such as Figure 1 As shown, the primary processing device 6 includes a screw drive base 61, a first milling cutter device 62 and a punching device 63. The first milling cutter device 62 and the punching device 63 are installed in parallel. The first milling cutter device 62 and the punching device 63 are transmission-connected to the screw drive base 61. The screw drive base 61 is an existing common screw drive mechanism and will not be introduced here. Driven by the screw drive base 61, the first milling cutter device 62 and the punching device 63 can move along the length direction of the screw drive base 61. The first milling cutter device 62 and the punching device 63 can pass through the primary processing station 32 in sequence to complete the grooving and punching operations in sequence. The first milling cutter device 62 is equipped with a first milling cutter 621, as shown in FIG. Figure 6 As shown, when the first milling cutter device 62 moves to the primary processing station 32, the groove on the outer wall of the bearing outer ring workpiece is milled by the lateral movement of the first milling cutter 621 (the bearing outer ring workpiece is in an upright state, so the outer wall groove can be processed). After the first milling cutter device 62 completes the operation, the punching device 63 moves to the primary processing station 32, as shown in FIG. Figure 7 As shown, three drill rods are installed on the drilling device 63, which drill holes downward at the same time to complete the drilling operation of three oil filling holes at the same time.

[0036] The second processing of the bearing outer ring workpiece is to open a groove for installation and positioning on the side wall of the ring, such as Figure 1As shown, the secondary processing device 7 includes a second milling cutter device 71 and a telescopic push cylinder 73. The second milling cutter device 71 is connected to the piston rod end of the telescopic push cylinder 73. The telescopic push cylinder 73 can drive the second milling cutter device 71 to move telescopically. When the second milling cutter device 71 moves toward the secondary processing station 33, it can perform the side end face groove processing operation. Since the outer wall groove and the side end face groove have position requirements, the second milling cutter device 71 is installed with a second milling cutter 711 and a positioning plug-in 72. The second milling cutter 711 and the positioning plug-in 72 The positional relationship is fixed. When the positioning plug-in 72 is first positioned and inserted into the groove machined by the first milling cutter device 62, and then the side end face groove machined by the second milling cutter 711, its position accuracy can meet the requirements. The positioning plug-in 72 includes a rod frame 721 and a positioning rod 722. The rod frame 721 matches the outer wall groove size of the bearing outer ring workpiece. When positioning, the rod frame 721 falls into the outer wall groove of the bearing outer ring workpiece, and the positioning rod 722 is inserted into the three oiling holes, so that the second milling cutter 711 can be accurately positioned.

All technical solutions based on the concept of the present invention are within the scope of protection of the present invention.
