Description

Technical Field

[0001] The present invention relates to the cutting technology of bearing steel pipes, and particularly to a cutting device for bearing processing. Background Art

[0002] During the bearing processing, both the inner and outer rings of the bearing need to be cut. The existing cutting devices generally place the pipe directly on the V-shaped support table for positioning and movement, and only need to push the pipe to move on the V-shaped support table to perform continuous operations. For example, in the Chinese invention patent with the publication number CN117718532A, a precision automobile bearing processing and cutting device is disclosed. It drives two centering clamping components to synchronously perform clamping movements through the opening and clamping components, clamps the steel pipe in the center, and the cut end and the end of the steel pipe in the incoming material direction are respectively clamped and fixed by the two centering clamping components. The steel pipe will not shift during cutting, avoiding subsequent incision correction and improving the cutting accuracy of the bearing ring.

[0003] Another example is the Chinese invention patent with the publication number CN117123844A, which discloses a raw material truncation device for bearing seat ring processing. Its automated adjustment structure can further improve the processing efficiency of the bearing seat ring, enabling the ring to be cut without manually adjusting the limiting structure according to the different thicknesses of each cut.

[0004] However, due to the increased weight of the pipe, the contact between its surface and the surface of the support table is relatively tight, and the resistance encountered during the movement of the pipe is large. Directly moving the pipe easily causes surface wear of the pipe, and the defects that appear on the support table after wear are also likely to cause deviation in the positioning of the pipe, thus affecting the quality and cutting effect of the pipe. Summary of the Invention

[0005] The purpose of the present invention is to provide a cutting device for bearing processing to solve the above deficiencies in the prior art.

[0006] To achieve the above purpose, the present invention provides the following technical solution: A cutting device for bearing processing, including a workbench and a cutting device, further including:

[0007] A support table, on which a placement groove is provided, and the placement groove is used for placing the pipe to be cut;

[0008] A cutting station, which is composed of two parallel clamping members. The clamping members clamp the pipe, and there is a gap between the two clamping members for the cutter of the cutting device to move.

[0009] A conveying mechanism, which is used to move pipe fittings to a cutting station. The conveying mechanism includes a lifting member and a pushing member. The lifting member is arranged at the bottom of one end of the placing groove close to the cutting station, and is used to move the pipe fitting so that one end thereof is away from the placing groove. The pushing member is arranged at the bottom of the other end of the placing groove away from the cutting station, and can move along the length direction of the placing groove and push the pipe fitting towards the cutting station.

[0010] Further, the lifting member includes a bracket, which can move in the vertical direction to have a first state away from the bottom of the pipe fitting and a second state to move the pipe fitting away from the placing groove. The bracket is connected to an A driving member for driving its movement.

[0011] Further, the pushing member includes a push plate, and the push plate is connected to a B driving member for driving its movement.

[0012] Further, the B driving member includes a slide table. The push plate is installed on the slide table. Two guide rods are respectively slidably connected to both ends of the slide table. The two guide rods are located at the bottom of the placing groove and are fixedly connected to the inner walls of both ends of the support table.

[0013] Further, the pushing member further includes two supporting rods, and the two supporting rods are installed on one side of the push plate close to the cutting station through an adjusting member. The two supporting rods can move in the vertical direction to a position where they abut against the bottom of the pipe fitting. The bottom of the push plate is rotatably connected to the top of the slide table, and the rotation axis at the rotation connection is located on one side away from the plane where the end of the pipe fitting is located.

[0014] Further, the adjusting member includes a slider. A chute is formed on one side of the push plate. The slider is slidably connected to the chute. The two supporting rods are symmetrically installed on one side of the slider. A threaded rod is threadedly connected to the inner wall of the slider. One end of the threaded rod is rotatably connected to the inner wall of the push plate, and the other end of the threaded rod penetrates through the push plate and is rotatably connected to the inner wall of the push plate.

[0015] Further, the A driving member includes a disk-shaped cam. One side of the disk-shaped cam is fixedly connected to a rotating shaft. A roller is arranged above the disk-shaped cam and abuts against its side surface. The center of the roller is rotatably connected to a rotating rod. One end of the rotating rod is fixedly connected to the bottom of the bracket. The A driving frame further includes a horizontally arranged hollow frame body. The rotating rod is located in the middle of the hollow frame body, and the other end thereof is rotatably connected to the hollow frame body. Two slide rods are fixedly connected to both ends of the frame body. The slide rods are slidably connected to the inner wall of the support table. One end of the rotating shaft is connected to a motor for driving its rotation.

[0016] Further, the B driving member includes a cylindrical cam and a follower rod. The follower rod abuts against one side of the cylindrical cam. One end of the follower rod is fixedly installed at one end of the hollow frame body, and the axis of the follower rod is parallel to the axis of the rotating shaft. A ratchet limiting member is arranged between the sliding table and the hollow frame body. A sliding column is fixedly installed at the other end of the hollow frame body. The surface of the sliding column is slidably connected to the inner wall of the support table. A second spring is arranged at one end of the sliding column. The elastic force of the second spring acts on the sliding column to make the sliding column tend to move away from the cylindrical cam.

[0017] Further, the ratchet limiting member includes two ratchet plates arranged on the top of the hollow frame body. A ratchet block which is in limiting cooperation with them is arranged above the two ratchet plates. An activity cavity for the two ratchet blocks to slide longitudinally is opened in the sliding table. The tops of the two ratchet blocks are fixedly connected by the same connecting plate. Two first springs are installed in the activity cavity. The elastic force of the first springs acts on the connecting plate and the two ratchet blocks to make them tend to move downward. A pull rod is fixedly connected to the top of the connecting plate. One end of the pull rod penetrates through the sliding table and is slidably connected to the top of the sliding table.

[0018] Compared with the prior art, a cutting device for bearing processing provided by the present invention has the following beneficial effects:

[0019] 1. For the cutting device for bearing processing, by arranging a jacking member and a pushing member, the pipe fitting is jacked up to a certain height, so that the contact surface between the pipe fitting and the placement groove is separated, reducing the friction and resistance during the movement of the pipe fitting, and making the pipe fitting and the placement groove no longer contact frequently, significantly reducing wear and improving the service life of the equipment.

[0020] 2. For the cutting device for bearing processing, by only lifting one end of the pipe fitting, the pipe fitting moves in an inclined posture separated from the placement groove. Compared with arranging two jacking members at both ends of the pipe fitting to lift the pipe fitting simultaneously, when lifting the same maximum height, the center of gravity of the inclined pipe fitting is lower, its stability is higher, and the kinetic energy required to lift the pipe fitting is also relatively lower.

[0034] 100, pipe. Detailed implementation manners

[0035] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0036] For the embodiments, please refer to Figure 1 - Figure 10 , a cutting device 2 for bearing processing, including a workbench 1 and a cutting device 2, further including:

[0037] A support table 3, on which a placement groove 31 is provided, and the placement groove 31 is used to place the pipe 100 to be cut;

[0038] A cutting station 4, which is composed of two clamping members 41 arranged in parallel. The clamping members 41 clamp the pipe 100, and there is a gap between the two clamping members 41 for the cutter of the cutting device 2 to move;

[0039] A conveying mechanism 5, which is used to move the pipe fitting towards the cutting station 4. The conveying mechanism 5 includes a lifting member 51 and a pushing member 52. The lifting member 51 is arranged at the bottom of one end of the placement groove 31 close to the cutting station 4, and is used to move the pipe fitting so that one end thereof is away from the placement groove 31. The pushing member 52 is arranged at the bottom of the other end of the placement groove 31 away from the cutting station 4, and can move along the length direction of the placement groove 31 and push the pipe fitting towards the cutting station 4.

[0040] In an embodiment of the present invention, the cross-section of the placement groove 31 is V-shaped, and a through groove 32 is provided at the bottom of the support table. When performing cutting operations, place the steel pipe to be cut in the placement groove 31, as Figure 1 shown;

[0041] In an embodiment of the present invention, the lifting member 51 includes a bracket 511, and the bracket 511 can move in the vertical direction to have a first state away from the bottom of the pipe fitting and a second state to move the pipe fitting away from the placement groove 31. The bracket 511 is connected to an A driving member 512 for driving its movement;

[0042] In the second state, the bracket 511 moves upward and passes through the through groove 32, jacking up one end of the pipe fitting by a certain height, so that the axial direction of the pipe fitting forms a certain inclination angle with the length direction of the placement groove 31. At this time, the contact position between the surface of the pipe fitting and the surface of the placement groove 31 is reduced, and only the end away from the cutting station 4 still contacts the surface of the placement groove 31. Then, the pushing member 52 provided at this end is used to push the pipe fitting to move.

[0043] In an embodiment of the present invention, the pushing member 52 includes a push plate 521, and the push plate 521 is connected to a B driving member 522 for driving its movement;

[0044] In an embodiment of the present invention, the B driving member 522 includes a sliding table 5221, a push plate 521 is installed on the sliding table 5221, two guide rods 5222 are respectively slidably connected to both ends of the sliding table 5221, and the two guide rods 5222 are located at the bottom of the placement groove 31 and fixedly connected to the inner walls of both ends of the support table 3;

[0045] Compared with the way of directly pushing the pipe fitting to move on the placement groove 31 of the support table 3, after the pipe fitting is lifted by a certain height, the contact surface between the pipe fitting and the placement groove 31 is separated, which is beneficial to reducing the resistance suffered by the pipe fitting during movement and the wear degree between the pipe fitting and the placement groove 31. It should be noted that after one end of the pipe fitting is lifted, a part of its weight acts on the bracket 511, and part of the weight also acts on the contact part between the other end of the pipe fitting and the placement groove 31, and the contact area of this part is very small. At this time, the force required to push the pipe fitting to move is also small. However, this will cause the wear of this part to be aggravated. Therefore, a way to solve the above problems is provided. Specifically:

[0046] The pushing member 52 further includes two support rods 523, and the two support rods 523 are installed on the side of the push plate 521 close to the cutting station 4 through an adjusting member 524. The two support rods 523 can move vertically to a position where they abut against the bottom of the pipe fitting. The bottom of the push plate 521 is rotatably connected to the top of the sliding table 5221, and the axis line of the rotating shaft 5122 at the rotating connection is located on the side away from the plane where the end of the pipe fitting is located. As Figure 7 shown, it should be noted that the purpose of the axis line of the rotating shaft 5122 being located on the side away from the plane where the end of the pipe fitting is located is to ensure that when the push plate 521 rotates, the end of the pipe fitting will not move towards the surface of the placement groove 31, but will be separated from the surface of the placement groove 31;

[0047] When one end of the pipe fitting is lifted, the other end will be supported by the two support rods 523, and the push plate 521 will rotate by a certain angle. At this time, the end of the pipe fitting located at the push plate 521 will also be separated from the surface of the placement groove 31. The movement of the push plate 521 will cause the pipe fitting to move in an inclined posture separated from the placement groove 31. Compared with the prior art in which two lifting members 51 are provided at both ends of the pipe fitting to lift the pipe fitting simultaneously, when lifting the same maximum height, the center of gravity of the inclined pipe fitting is lower, its stability is higher, and the kinetic energy required to lift the pipe fitting is also relatively lower;

[0048] In this way, the pipe fitting can be limited within the placement groove 31 during cutting, and can be separated from the placement groove 31 during the movement after cutting (for the next cutting operation), avoiding friction between the pipe fitting and the placement groove 31 during the movement of the pipe fitting.

[0049] In one embodiment of the present invention, the adjusting member 524 includes a slider 5241. A chute 5242 is formed on one side of the push plate 521. The slider 5241 is slidably connected to the chute 5242. Two support rods 523 are symmetrically installed on one side of the slider 5241. A threaded rod 5243 is threadedly connected to the inner wall of the slider 5241. One end of the threaded rod 5243 is rotatably connected to the inner wall of the push plate 521. The other end of the threaded rod 5243 penetrates through the push plate 521 and is rotatably connected to the inner wall of the push plate 521. The upper end of the threaded rod 5243 extends above the push plate 521 and is connected with a rotating handle. By rotating the threaded rod 5243, the support position of the support rod 523 is adjusted. When adjusting, the two support rods 523 should be pressed against the bottom of the pipe fitting, so that the pipe fitting can be supported by the two support rods 523 when the other end of the pipe fitting is lifted up.

[0050] In one embodiment of the present invention, another moving mode of the jacking member 51 and the pushing member 52 is provided. Specifically:

[0051] The A driving member 512 includes a disk-shaped cam 5121. A rotating shaft 5122 is fixedly connected to one side of the disk-shaped cam 5121. A roller 5123 is arranged above the disk-shaped cam 5121 and abuts against its side surface. A rotating rod 5124 is rotatably connected to the center of the roller 5123. One end of the rotating rod 5124 is fixedly connected to the bottom of the bracket 511. The A driving frame further includes a horizontally arranged hollow frame body 5125. The rotating rod 5124 is located in the middle of the hollow frame body 5125, and the other end thereof is rotatably connected to the hollow frame body 5125. Two sliding rods 5126 are fixedly connected to both ends of the frame body. The sliding rods 5126 are slidably connected to the inner wall of the support table 3.

[0052] One end of the rotating shaft 5122 is connected to a motor 5127 for driving its rotation. By driving the rotation of the rotating shaft 5122 to drive the rotation of the disk-shaped cam 5121, the disk-shaped cam 5121 drives the roller 5123 to move up and down in the vertical direction, so that the bracket 511 can move up and down. It should be understood that the maximum upward movement stroke corresponds to the rising height of the end of the pipe fitting, and the maximum downward movement stroke should separate the bracket 511 from the bottom of the pipe fitting so that the pipe fitting can be placed on the placement groove 31.

[0053] The B driving member 522 includes a cylindrical cam 5223 and a follower rod 5224. The follower rod 5224 abuts against one side of the cylindrical cam 5223. One end of the follower rod 5224 is fixedly installed at one end of the hollow frame body 5125, and the axis of the follower rod 5224 is parallel to the axis of the rotating shaft 5122. A ratchet limiting member 525 is arranged between the sliding table 5221 and the hollow frame body 5125. When the sliding table 5221 is under the action of the ratchet limiting member 525, it can only move along the pipe conveying direction. A sliding column 5258 is fixedly installed at the other end of the hollow frame body 5125. The surface of the sliding column 5258 is slidably connected to the inner wall of the support table 3. A second spring 5257 is arranged at one end of the sliding column 5258. The elastic force of the second spring 5257 acts on the sliding column 5258 to make the sliding column 5258 tend to move away from the cylindrical cam 5223. Specifically, one end of the second spring 5257 abuts against the side of the support table 3 away from the hollow frame body 5125. A retaining ring is arranged at the end of the sliding column 5258, and the other end of the second spring 5257 abuts against one side of the retaining ring;

[0054] One end of the follower rod 5224 can abut against the cylindrical cam 5223 through a set rotating wheel to reduce the friction between the follower rod 5224 and the cylindrical cam 5223.

[0055] The ratchet limiting member 525 includes two ratchet plates 5251 arranged on the top of the hollow frame body 5125. A ratchet block 5252 which is limited and matched with the two ratchet plates 5251 is arranged above the two ratchet plates 5251. An activity cavity 5253 for the two ratchet blocks 5252 to slide longitudinally is opened in the sliding table 5221. The tops of the two ratchet blocks 5252 are fixedly connected through the same connecting plate 5254. Two first springs 5255 are installed in the activity cavity 5253. The elastic force of the first springs 5255 acts on the connecting plate 5254 and the two ratchet blocks 5252 to make them tend to move downward. A pull rod 5256 is fixedly connected to the top of the connecting plate 5254. One end of the pull rod 5256 penetrates through the sliding table 5221 and is slidably connected to the top of the sliding table 5221;

[0056] The follower moves horizontally under the drive of the cylindrical cam 5223 and in cooperation with the second spring 5257, thereby driving the hollow frame 5125 to move. When the hollow frame 5125 moves towards the cutting station 4, the ratchet plate 5251 engages with the ratchet block 5252, causing it to drive the slide 5221 to move a fixed distance. When the hollow frame 5125 moves away from the cutting station 4, the teeth on the ratchet plate 5251 push the ratchet block 5252 to compress the first spring 5255, so that the movement of the ratchet plate 5251 does not drive the slide 5221 to move. It should be noted that when the hollow frame 5125 moves away from the cutting station 4, the setting of the first spring 5255 should satisfy that the maximum thrust of the ratchet plate 5251 acting on the ratchet block 5252 to contract it is not greater than the minimum force when the slide 5221 can move along the guide rod 5222.

[0057] In an embodiment of the present invention, the two ratchet blocks 5252 can also be arranged to move independently, and the teeth of the two ratchet plates 5251 are arranged staggeredly, as Figure 9 shown. At this time, the opposite side of the ratchet block 5252 is slidably connected to the connecting plate 5254, and the two first springs 5255 act on the two ratchet blocks 5252 respectively. By staggering the teeth of the ratchet plate 5251 by a certain distance, the minimum moving distance of the cooperation between the ratchet plate 5251 and the ratchet block 5252 is reduced. That is to say, when the two ratchet plates 5251 are basically symmetrically arranged, the cooperation between the ratchet block 5252 and the ratchet plate 5251 requires at least the distance between two adjacent teeth to move to ensure that the movement of the ratchet plate 5251 can push the ratchet block 5252. By setting the two ratchet plates 5251 to stagger by a certain distance, this minimum moving distance is reduced. For example, the teeth on the ratchet plate 5251 can be located at the middle position between two teeth on the opposite side of another ratchet plate 5251 (see Figure 10 , the two dotted lines indicate the staggered positions). At this time, the minimum distance will be shortened to half of the distance between two adjacent teeth, which makes the moving distance of the pipe fitting more consistent each time it is cut, and further makes the width tolerance of the cut pipe fitting smaller, improving the dimensional stability of the cutting operation;

[0058] In an embodiment of the present invention, the disk cam 5121 and the cylindrical cam 5223 have a certain cooperation mode. The disk cam 5121 and the cylindrical cam 5223 are fixedly connected as a whole to form a driving cam. The driving cam is divided into four rotation intervals, namely the first interval (a1, b1), the second interval (a2, b2), the third interval (a3, b3) and the fourth interval (a4, b4), see Figure 6 (the dotted lines indicate the boundary positions of each interval, a is the position corresponding to the disk cam 5121, and b is the position corresponding to the cylindrical cam 5223). Taking Figure 6During the clockwise rotation in the indicated direction (the hollow arrow indicates the positions of the roller 5123 and the driven wheel), when in the first interval, the bracket 511 switches to the second state and the pusher 52 does not act; when in the second interval, the bracket 511 maintains the second state and the pusher 52 moves the pipe fitting towards the cutting station 4; when in the third interval, the bracket 511 switches to the first state and the pusher 52 does not act; when in the fourth interval, the bracket 511 maintains the first state and the pusher 52 does not act (the hollow bracket moves away from the cutting station 4, but due to the action of the ratchet limiting member 525, the pusher 52 does not return).

[0059] By integrating the disk cam 5121 and the cylindrical cam 5223, the driving cam can precisely control the movements of the bracket 511 and the pusher 52. Especially when the state of the bracket 511 switches, it can respond in a timely manner, ensuring that the movement process of the pusher 52 is stable and precise, effectively improving the working efficiency and operation accuracy of the system, reducing the number of components, making the overall equipment more compact and easy to install; the integrated design also makes the transmission between the disk cam 5121 and the cylindrical cam 5223 more direct, reducing the contact and friction between multiple components, helping to extend the service life of the equipment, and reducing the frequency and cost of maintenance; since the disk and the cylindrical cam 5223 are fixedly connected as a whole, the adjustment and calibration process also becomes simple, reducing the complex steps that may be encountered when adjusting each cam individually.

[0060] In an embodiment of the present invention, the clamping member 41 includes a base 411 and a pressing plate 412. The base 411 is also V-shaped and is adapted to the height of the placement groove 31. The pressing plate 412 can move in the vertical direction, so as to press the pipe fitting against the base 411 when the cutting device 2 cuts the pipe fitting. After cutting is completed, the pressing plate 412 moves upward to release the pressing state and moves to a height that does not obstruct the conveyance of the pipe fitting. The movement of the pressing plate 412 can be driven by a cylinder or a hydraulic cylinder or an electric telescopic rod, which is a prior art and will not be specifically described herein.

[0061] The specific implementation scenario of the cutting device 2 is as follows:

[0062] Equipment stage:

[0063] Place the pipe fitting to be cut in the placement groove 31 of the support table 3, move the sliding table 5221 so that the push plate 521 abuts against the end of the pipe fitting, and then rotate the threaded rod 5243 to adjust the position of the support rod 523 so that the support rod 523 abuts against the lower part of the end of the pipe fitting to provide a certain supporting force, adjust the position of the pipe fitting so that it is located at the cutting station 4.

[0064] Cutting stage:

[0065] Start the cutting device 2, the cutter of the cutting device 2 moves downward, and moves along the gap between the two clamping members 41 until the pipe fitting is cut completely;

[0066] Next, the pressing plates 412 of the two clamping members 41 move upward, and the lifting member 51 and the pushing member 52 of the conveying mechanism 5 cooperate to drive the pipe fitting to move. Specifically, one end of the pipe fitting close to the cutting station 4 is first lifted by a certain height to make it in an inclined posture. At this time, the other end of the pipe fitting is also separated from the surface of the placement groove 31 under the support of the push plate 521 and the support rod 523. Then, the pushing member 52 moves the inclined pipe fitting towards the cutting station 4. Due to the setting of the cylindrical cam 5223 and the cooperation of the ratchet limiting member 525, the pipe fitting moves a certain distance. After the movement, the lifting member 51 descends to lower the end of the pipe fitting, and the pipe fitting will be placed horizontally in the placement groove 31 and the clamping member 41. Starting the cutting device 2 can complete the cutting here. At the same time, the driving cam continues to rotate, and the hollow bracket will return to the starting position, and the above process will be continued during the next cutting, so as to continuously cut the pipe fitting. The cut product is the semi-finished bearing outer ring. Collecting the cut semi-finished products can then be further processed.

[0067] In an embodiment of the present invention, since debris will be generated during the cutting process, some debris may remain on the supporting plane of the base 411 of the clamping member 41. Whether the pipe fitting is directly pushed on the placement groove 31 or the pipe fitting is moved in an inclined posture in this solution, the presence of debris may cause a gap (blocked between the pipe fitting and the corresponding supporting plane) at the contact position between the pipe fitting and the supporting plane and the surface of the placement groove 31, resulting in a certain inclination of the cutting surface during cutting and affecting the stability of the cutting size. In the way of directly pushing the pipe fitting on the placement groove 31, since there is always a pipe fitting at the clamping member 41 close to the pipe fitting during operation, the debris at this place is often difficult to clean. Once the debris is relatively large and gets stuck between the pipe fitting and the corresponding supporting plane during the process of pushing the pipe fitting to move, it is easier to cause deeper scratches on the surface of the pipe fitting or the end of the pipe fitting to warp. Even through the fixation of the clamping member 41, it is difficult to eliminate. By lifting the end of the pipe fitting when the pipe fitting moves, the pipe fitting can be separated from the supporting plane of the clamping member 41. After separation, the debris will be able to move away under its own weight. Further, a nozzle (not shown in the figure) can be provided at the clamping member 41. The nozzle faces the supporting plane, and the nozzle is connected to a gas source and sprays gas with a certain pressure to blow the debris at the corresponding part, so that the corresponding supporting plane can be kept clean every time the pipe fitting moves. It should be understood that the supporting plane refers to the surface of the pipe fitting when it is in the cutting state, its surface and the surface of the base 411 of the clamping member 41 and the surface of the placement groove 31 near the cutting device 2 (the range where the cutting debris can move).

[0068] In one embodiment of the present invention, the cutting device 2 further includes a blanking plate 6 disposed at the cutting station 4. After the pipe fitting is cut, by the above-described moving manner of the pipe fitting, when the pipe fitting is lifted to a certain height and conveyed to the cutting station 4, the to-be-cut end of the pipe fitting can push the top of the outer ring of the bearing standing on the base 411 after cutting, causing it to fall on the blanking plate 6 and finally slide into the collection box 7.

[0069] Only some exemplary embodiments of the present invention have been described by way of illustration above. Without doubt, for those of ordinary skill in the art, the described embodiments can be modified in various different ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and description are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
