Description

Technical Field

[0002] The groove processing of the existing bearing inner ring and outer ring usually requires two processes, namely rough processing and fine processing, and the rough processing and fine processing are respectively processed by two different grinders. Among them, the rough processing is directly completed by the grinder, and the fine processing is completed by the superfinishing machine.

[0003] Since different equipment is used, manual transfer is required. In addition, the friction of rough machining and fine machining also requires manual loading. This leads to more manual intervention in the groove machining of the inner and outer rings of the bearing, which affects the overall production efficiency and is not conducive to cost control.

DETAILED DESCRIPTION

[0041] The present application is further described in detail below in conjunction with the accompanying drawings.

[0042] In the description of the present application, it should be understood that the terms "up", "down", "left", "right", etc., indicating directions or positional relationships are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as a limitation on the present application.

[0043] An automated bearing grinding production line, such as Figure 1 As shown, it includes a feeder 10, a transfer mechanism 40, at least one grinder 20 and at least one superfinishing machine 30. The number of grinders 20 and superfinishing machines 30 is the same. In this embodiment, two grinders 20 and two superfinishing machines 30 are provided.

[0044] Refer to the attached Figure 2 and Figure 3The loader 10 includes a loader body 100, a loader cart 110, a loader conveying mechanism 130, and a loader robot 120 for transferring materials on the loader cart 110 to the loader conveying mechanism 130. The loader conveying mechanism 130 and the loader robot 120 are installed on the loader body 100. An opening for the loader cart 110 to enter is provided on the loader body 100. The parts, i.e., the inner rings or outer rings of the bearings, are arranged and stacked on the loader cart 110. The stacking requirement is that multiple axial arrangements are placed to form an arrangement on a horizontal plane, and then stacked in the vertical direction to form multiple layers.

[0045] The loading robot 120 includes a horizontally arranged insertion rod 122 and a three-axis moving mechanism 121 for driving the insertion rod 122 to move. The three-axis moving mechanism 121 can drive the insertion rod 122 to perform XYZ three-axis movement. By controlling the three-axis moving mechanism 121 to control the insertion rod 122 to penetrate into the axially arranged parts, a row of parts arranged axially can be taken out.

[0046] The feeding and conveying mechanism 130 includes a conveyor belt 131 and a pushing cylinder 132. The feeding end of the conveyor belt 131 is located inside the loader body 100, and the discharging end extends out of the loader body 100. The pushing cylinder 132 is arranged at the discharging end of the conveyor belt 131, and the feeding end is provided with a U-shaped baffle 133 for removing parts from the insertion rod 122.

[0047] When the loading robot 120 unloads, the insertion rod 122 and the parts thereon are placed together at the feed end of the conveyor belt 131, and the insertion rod 122 needs to be mounted on the U-shaped baffle 133, and the parts are all located on the conveyor belt 131. At this time, the axial movement of the insertion rod 122 is controlled along its length to separate the insertion rod 122 from the parts, and the conveyor belt 131 transports the parts box to the discharge end.

[0048] Refer to the attached Figure 3 and Figure 4 The transfer mechanism 40 includes a plurality of material storage boxes 410, a transfer manipulator 420 that can move between the material storage boxes 410 and the feeding port of the grinding machine 20 or / and the superfinishing machine 30, and a truss 430 for the transfer manipulator 420 to slide and install. The number of the material storage boxes 410 is the sum of the number of the feeder 10 and the grinding machine 20, and the material storage boxes 410 are connected with the discharge port of the feeder 10 and the discharge port 22 of the grinding machine. After the conveyor belt 131 on the feeder 10 transports the parts to the discharge end, the parts are pushed into the material storage box 410 by the push cylinder 132.

[0049] The storage box 410 is tilted, and a rotating cylinder 411 is provided at the bottom of the storage box 410. The height of the storage box 410 is lower than the diameter of the part. The tilt direction of the storage box 410 is changed by rotating the cylinder 411 so that it can cooperate with the transfer robot 420 to realize part grabbing.

[0050] The truss 430 is located above the grinder 20 and the superfinishing machine 30, and the transfer robot 420 is a lifting robot. The transfer robot 420 includes a lifting assembly 421 slidably mounted on the truss 430, and a clamp 422 mounted below the lifting assembly 421. The clamp 422 includes two clamps with inclined bottoms. The two clamps are controlled by a clamping cylinder to achieve a clamping action. The parts are clamped by the tilting setting of the bottom of the clamp and the tilting of the storage box 410. Among them, the upper loading port 21 of the grinder and the upper loading port 31 of the superfinishing machine are both inclined channels, and the inclination directions of the clamps, the upper loading port 21 of the grinder and the upper loading port 31 of the superfinishing machine are the same.

[0051] like Figure 5 As shown, the grinder 20 includes a main body 200, and a feed channel 210, a discharge channel 220, a grinding disc 230, a placement mechanism 240, a swing arm 250 and a driving element 260 installed on the main body 200. The feed channel 210 and the discharge channel 220 are both inclined. The top end of the feed channel 210 is the feed port of the grinder 20, the bottom end of the discharge channel 220 is the discharge port 22 of the grinder, and the top end is the drop port.

[0052] The placement mechanism 240 is located at one side of the grinding disc 230 . A material collector 280 is provided at the bottom end of the feed channel 210 . The driving element 260 is a motor. The driving element 260 can control the swing arm 250 to swing back and forth between the material collector 280 and the placement mechanism 240 .

[0053] The material collector 280 includes a material collecting barrel 281 whose upper end is connected to the feeding channel 210, a limit baffle 282 located at the bottom of the material collecting barrel 281 and rotatably connected to the main body 200, and a reset member 283 for providing an upward rotation tendency force to the limit baffle 282. The reset member 283 can be a torsion spring, a tension spring or a compression spring. In this embodiment, the reset member 283 is a compression spring. The swing arm 250 is provided with an insertion shaft that can be inserted into the part. After the insertion shaft is inserted into the part, the swing arm 250 swings to perform the feeding action. When feeding, the part is driven to overcome the tendency force of the reset member 283 to make the limit baffle 282 rotate downward.

[0054] In addition, in order to avoid the situation that when there are no parts in the collecting barrel 281, the insertion of the insertion shaft causes the parts to be blocked and unable to fall, thereby causing the swing arm 250 to rotate idly. Figure 7 An elastic positioning bead 2821 is provided on one of the limit baffle 282 and the main body 200, and an arc groove 2822 cooperating with the elastic positioning bead 2821 is provided on the other. In this embodiment, the elastic positioning bead 2821 is provided on the limit baffle 282, and the arc groove 2822 takes the rotation axis of the limit baffle 282 as the center of the circle.

[0055] Among them, when the limit baffle 282 is not subjected to force and when subjected to force, the elastic positioning beads 2821 are respectively located at the two ends of the arc groove 2822. In this embodiment, they are located at the top of the arc groove 2822 when not subjected to force, and at the bottom of the arc groove 2822 when subjected to force. In this way, when the swing arm 250 is reset to the position of the collector 280, when the limit baffle 282 is not subjected to external force, the limit baffle 282 is located on the moving path of the plug shaft, so that the plug shaft will be blocked by the limit baffle 282 until the part falls and pushes the limit baffle 282 to rotate clockwise to avoid the plug shaft, so that the plug shaft can be directly inserted into the part; and when subjected to force, the limit baffle 282 is located below the moving path of the plug shaft.

[0056] The stress state refers to Figure 6 The state shown in the figure is when a part is located above the limit baffle 282, while the unstressed state refers to the state when there is no part on the limit baffle 282. When the swing arm 250 is feeding, the swing arm 250 drives the part to move, so that the limit baffle 282 moves downward. During this process, the elastic positioning bead 2821 is forced to shrink and separate from the arc groove 2822. After the part is separated from the limit baffle 282, the limit baffle 282 rotates counterclockwise under the action of the restoring force of the restoring member 283, so that the elastic positioning bead 2821 returns to the arc groove 2822, and the limit baffle 282 returns to the stressed state or the unstressed state.

[0057] A limiting plate 201 is provided on the main body 200 . The limiting plate 201 is located above the blanking opening of the discharge channel 220 . A channel for parts to pass through is formed between the limiting plate 201 and the main body 200 .

[0058] Refer to the attached Figure 8 and Fig. 9 The swing arm 250 can slide axially on the rotating shaft of the driving element 260. Specifically, a slider 251 is provided on the swing arm 250, and a slide groove 261 is provided on the rotating shaft. A spring 263 is provided between the swing arm 250 and the rotating shaft of the driving element 260 to provide the swing arm 250 with a tendency to move toward the main body 200. A positioning pin 252 is provided between the swing arm 250 and the rotating shaft of the driving element 260 for axially positioning the swing arm 250 away from the main body 200. A positioning hole 262 is provided on the rotating shaft for inserting the positioning pin 252. A spring is provided at one end of the positioning pin 252 away from the rotating shaft to keep it in contact with the rotating shaft.

[0059] The swing arm 250 is provided with a limit switch 253 for releasing the positioning pin shaft 252, and the main body 200 is provided with a limit block 202 for cooperating with the limit switch 253. During operation, when the driving element 260 controls the swing arm 250 to reset back to the position of the collector 280, the limit switch 253 abuts against the limit block 202 and makes the limit switch 253 in a state of releasing the positioning pin shaft 252, so that the swing arm 250 moves toward the main body 200 to insert the insertion shaft into the part.

[0060] The limit switch 253 is a block slidably mounted on the swing arm 250, the other end of the block extends out of the swing arm 250, and the sliding direction of the block is perpendicular to the swing arm 250 and the rotating shaft. A spring is also installed between the limit switch 253 and the swing arm 250, and the spring keeps the limit switch 253 moving away from the positioning pin shaft 252.

[0061] Among them, in this embodiment, a through hole 2521 is provided in the middle position of the positioning pin shaft 252 for the limit switch 253 to pass through, and a guiding inclined surface cooperating with the building block is provided in the through hole 2521, so that after the limit switch 253 is inserted into the through hole 2521, the positioning pin shaft 252 can be pushed to move upward to compress the spring. At this time, the positioning pin shaft 252 is separated from the positioning hole 262, and under the trend force of the closing spring 263, the insertion shaft on the swing arm 250 moves toward the main body 200 and is inserted into the part.

[0062] like Figure 5 and Fig.10 As shown, a separation device 270 is provided between the swing arm 250 and the main body 200, which can drive the swing arm 250 to slide axially. The separation device 270 includes a guide block 272 provided on the swing arm 250, and a one-way guide assembly 271 for cooperating with the guide block 272. Fig.11 and Fig.12 The one-way guide assembly 271 includes an arc-shaped guide rail 2711 arranged on the outside of the discharge channel 220, a sliding block 2712 slidably installed on the arc-shaped guide rail 2711, a return spring 2713 for keeping the sliding block 2712 at the end of the arc-shaped guide rail 2711 close to the collecting barrel 281, a guide member 2714 slidably installed on the sliding block 2712, and an elastic member 2715 for keeping the guide member 2714 against the bottom of the arc-shaped guide rail 2711.

[0063] The sliding block 2712 is in an arc-shaped structure, so that it can slide on the arc-shaped guide rail 2711 along the arc direction. A mounting groove is provided on one side of the arc-shaped guide rail 2711. The sliding block 2712 is installed by inserting a bolt from outside the mounting groove and rotating it to connect to the sliding block 2712. The bolt does not abut against the side wall of the arc-shaped guide rail 2711, and only limits the sliding block 2712 in the groove depth direction so that it will not separate from the arc-shaped guide rail 2711. In addition, it should be noted that the structure using bolts is relatively simple, but it does not mean that the sliding block 2712 can only be connected in this way.

[0064] Refer to the attached Fig.13 The bottom of the arc guide rail 2711 is an inclined surface, and one end close to the collecting barrel 281 is higher than the other end. The maximum depth of the arc guide rail 2711 is greater than or equal to the length of the guide member 2714. The end surface of the guide member 2714 that contacts the arc guide rail 2711 is set in an arc shape to reduce friction.

[0065] A guide slope 2721 is provided on the side of the guide block 272 away from the grinding disc 230 or / and the side of the guide member 2714 facing the grinding disc 230. In this embodiment, the guide slope 2721 is provided on the side of the guide block 272 away from the grinding disc 230. In addition, in order to reduce the resistance when the swing arm 250 pushes the sliding block 2712 to move toward the grinding disc 230, a slope is also provided on the side of the guide member 2714 facing away from the grinding disc 230. When the swing arm 250 is reset to the position of the collector 280, the separation device 270 controls the swing arm 250 to move axially from the open state to the closed state, and the limit plate 201 limits the separation of the parts from the swing arm 250 so that the parts fall into the blanking port and enter the discharge channel 220.

[0066] In addition, a retaining spring 2716 is provided on the side of the sliding block 2712 relative to the reset spring 2713. When not under force, the sliding block 2712 is located between the two ends of the arc guide rail 2711. On the one hand, it can prevent the sliding block 2712 from colliding when it is reset; on the other hand, when the swing arm 250 is reset, when the sliding block 2712 moves toward the collector 280, under the action of the inclined surface of the bottom wall of the arc guide rail 2711, the guide member 2714 will extend further outward from the sliding block 2712 to form a protrusion. In this way, the axial movement distance of the swing arm 250 can be increased, thereby reducing the protrusion height of the guide block 272 on the swing arm 250, reducing the contact and collision with other components caused by its excessive height when the swing arm 250 swings to form interference.

[0067] An axial locking structure is provided between the swing arm 250 and the rotating shaft of the driving element 260. Fig.14As shown, the axial locking structure includes a docking groove 291 and a docking protrusion 292 respectively provided on the rotating shafts of the swing arm 250 and the driving element 260. In this embodiment, the docking groove 291 is provided on the rotating shaft of the driving element 260, and the docking protrusion 292 is provided on the swing arm 250. The docking protrusion 292 is located at one end of the slider 251 on the swing arm 250, and the docking groove 291 is communicated with the slide groove 261 provided on the rotating shaft.

[0068] In addition, a magnetic attraction structure is provided on the butt end surfaces of the butt groove 291 and the butt protrusion 292. When the swing arm 250 is in the split state, the butt groove 291 and the butt protrusion 292 are controlled to cooperate under the magnetic attraction force. In this way, when the swing arm 250 drives the parts to move toward the placement mechanism 240, under the action of magnetism, the butt groove 291 and the butt protrusion 292 are first matched, and then the shaft drives the swing arm 250 to swing. When passing through the guide 2714, the axial movement of the swing arm 250 is locked due to the cooperation of the butt groove 291 and the butt protrusion 292, so the guide 2714 can only be driven to move by compressing the reset spring 2713 until the swing arm 250 passes through the guide 2714 and reaches the placement mechanism 240.

[0069] During the process of the swing arm 250 returning to the position of the collector 280, the swing arm 250 rotates counterclockwise. When the guide block 272 contacts the guide member 2714, it should be noted that the magnetic attraction force of the docking groove 291 and the docking protrusion 292 is greater than the initial trend force of the retaining spring 2716. In this way, the retaining spring 2716 is compressed first to drive the guide member 2714 to move, and the guide block 272 will extend the protrusion outward when it moves. When the retaining spring 2716 reaches a certain trend force or the sliding block 2712 moves to the end, the docking groove 291 and the docking protrusion 292 are separated. Preferably, they are separated after the sliding block 2712 moves to the end. In this way, the extending height of the guide block 272 can be maximized. At the same time, it can also more stably drive the swing arm 250 to move axially. After the docking groove 291 and the docking protrusion 292 are separated, the guiding slope of the guide block 272 abuts against the guide member 2714, driving the swing arm 250 to move axially while swinging until the positioning pin shaft 252 is inserted into the positioning hole 262 to lock the swing arm 250 axially again.
