Abstract

This invention discloses a cutting device for bearing processing, relating to the field of bearing steel pipe cutting. It includes a worktable and a cutting device, as well as a support platform. A placement groove is provided on the support platform for placing the pipe to be cut. A conveying mechanism is used to move the pipe to the cutting station. The conveying mechanism includes a lifting component and a pushing component. The lifting component is located at the bottom of one end of the placement groove near the cutting station and is used to move the pipe away from the placement groove. The pushing component is located at the bottom of the other end of the placement groove away from the cutting station and can move along the length of the placement groove to push the pipe towards the cutting station. This bearing processing cutting device, by setting up the lifting component and the pushing component, lifts the pipe to a certain height, separating the contact surface between the pipe and the placement groove, reducing friction and resistance during the movement of the pipe, and preventing frequent contact between the pipe and the placement groove, significantly reducing wear and improving equipment lifespan.

Description

Technical Field

[0001] This invention relates to bearing steel tube cutting technology, specifically to a cutting device for bearing processing. Background Technology

[0002] In the bearing processing, both the inner and outer rings of the bearing need to be cut. Existing cutting devices generally use a V-shaped support platform for limiting and moving the pipe. The continuous operation can be achieved simply by pushing the pipe on the V-shaped support platform. For example, Chinese invention patent CN117718532A discloses a precision automotive bearing processing cutting device. It uses an opening clamping component to drive two central clamping components to perform synchronous clamping movements, clamping the steel pipe in the center. The end to be cut and the end of the steel pipe in the material direction are respectively clamped and fixed by the two central clamping components. The steel pipe will not shift when it is cut, avoiding subsequent cut correction and improving the cutting accuracy of the bearing ring.

[0003] For example, Chinese invention patent with publication number CN117123844A discloses a raw material cutting device for processing bearing races. Through an automated adjustment structure, it can further improve the processing efficiency of bearing races, so that the limiting structure does not need to be manually adjusted according to the different thicknesses of each cut when the race is being cut.

[0004] However, due to the increased weight of the pipe fittings, their surface is in closer contact with the surface of the support platform. The resistance encountered when the pipe fittings move is greater, and direct movement of the pipe fittings can easily lead to surface wear. Defects that appear on the support platform after wear can also easily cause positioning deviations of the pipe fittings, thus affecting the quality of the pipe fittings and the cutting effect. Summary of the Invention

[0005] The purpose of this invention is to provide a cutting device for bearing processing to overcome the above-mentioned shortcomings of the prior art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a cutting device for bearing processing, comprising a worktable and a cutting device, and further comprising:

[0007] A support platform with a placement slot for placing the pipe to be cut.

[0008] The cutting station consists of two parallel clamping members that hold the pipe, and there is a gap between the two clamping members that allows the cutter of the cutting device to move.

[0009] A conveying mechanism for moving a pipe fitting to a cutting station includes a lifting member and a pushing member. The lifting member is located at the bottom of one end of the placement groove near the cutting station and is used to move the pipe fitting away from one end of the placement groove. The pushing member is located at the bottom of the other end of the placement groove away from the cutting station and is capable of moving along the length of the placement groove and pushing the pipe fitting toward the cutting station.

[0010] Furthermore, the lifting member includes a bracket that is movable in a vertical direction to have a first state away from the bottom of the pipe and a second state away from the placement slot, the bracket being connected to a drive member A for driving its movement.

[0011] Furthermore, the pusher includes a push plate connected to a B-drive member for driving its movement.

[0012] Furthermore, the B driving component includes a slide table, a push plate is mounted on the slide table, and two guide rods are slidably connected to both ends of the slide table. The two guide rods are located at the bottom of the placement groove and are fixedly connected to the inner walls of both ends of the support platform.

[0013] Furthermore, the pusher also includes two support rods, which are installed on the side of the push plate near the cutting station via an adjusting component. The two support rods can move vertically to a position where they abut against the bottom of the pipe. The bottom of the push plate is rotatably connected to the top of the slide table, and the axis of rotation at the rotatable connection is located on the side away from the plane where the end of the pipe is located.

[0014] Furthermore, the adjusting component includes a slider, a groove is provided on one side of the push plate, the slider is slidably connected to the groove, two support 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 passes through the push plate and is rotatably connected to the inner wall of the push plate.

[0015] Furthermore, the A-drive component includes a disc-shaped cam, with a rotating shaft fixedly connected to one side of the disc-shaped cam. A roller is provided above the disc-shaped cam and abuts against its side. A rotating rod is rotatably connected to the center of the roller. One end of the rotating rod is fixedly connected to the bottom of the bracket. The A-drive frame also includes a horizontally arranged hollow frame. The rotating rod is located in the middle of the hollow frame, and its other end is rotatably connected to the hollow frame. Two sliding rods are fixedly connected to both ends of the frame. The sliding rods are slidably connected to the inner wall of the support platform. One end of the rotating shaft is connected to a motor for driving its rotation.

[0016] Furthermore, the B driving component includes a cylindrical cam and a driven rod. The driven rod abuts against one side of the cylindrical cam. One end of the driven rod is fixedly installed at one end of the hollow frame, and the axis of the driven rod is parallel to the axis of the rotation shaft. A ratchet limiting component is provided between the slide table and the hollow frame. A sliding column is fixedly installed at the other end of the hollow frame. The surface of the sliding column is slidably connected to the inner wall of the support platform. A second spring is provided 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] Furthermore, the ratchet limiting component includes two ratchet plates disposed on the top of the hollow frame, and ratchet blocks that cooperate with the ratchet plates for limiting. A movable cavity is provided in the slide table for the two ratchet blocks to slide longitudinally. The tops of the two ratchet blocks are fixedly connected by the same connecting plate. Two first springs are installed in the movable 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 passes through the slide table and is slidably connected to the top of the slide table.

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

[0019] 1. This cutting device for bearing processing, by setting up lifting and pushing components, lifts the pipe to a certain height, so that the contact surface between the pipe and the placement groove is separated, reducing the friction and resistance of the pipe during movement, and preventing the pipe from frequently contacting the placement groove, thus significantly reducing wear and improving the service life of the equipment.

[0020] 2. The cutting device for bearing processing moves the pipe in an inclined and separated posture by lifting only one end of the pipe. Compared with setting two lifting members at both ends of the pipe to lift the pipe at the same time, the inclined pipe has a lower center of gravity and higher stability for the same maximum lifting height, and the kinetic energy required to lift the pipe is also relatively low.

[0034] 100. Pipes. Detailed Implementation

[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 with reference to the accompanying drawings.

[0036] For examples, please refer to Figure 1 - Figure 10 A cutting device 2 for bearing processing includes a worktable 1 and a cutting device 2, and further includes:

[0037] Support platform 3, on which a placement groove 31 is provided, the placement groove 31 is used to place the pipe 100 to be cut;

[0038] The cutting station 4 consists of two parallel clamping members 41, which clamp the pipe 100, and there is a gap between the two clamping members 41 for the cutting blade of the cutting device 2 to move.

[0039] The conveying mechanism 5 is used to move the pipe to the cutting station 4. The conveying mechanism 5 includes a lifting member 51 and a pushing member 52. The lifting member 51 is located at the bottom of one end of the placement groove 31 near the cutting station 4. It is used to move the pipe so that one end is away from the placement groove 31. The pushing member 52 is located at the bottom of the other end of the placement groove 31 away from the cutting station 4. It can move along the length of the placement groove 31 and push the pipe to the cutting station 4.

[0040] In one embodiment of the present invention, the placement groove 31 has a V-shaped cross-section, and a through groove 32 is provided at the bottom of the support platform. During the cutting operation, the steel pipe to be cut is placed in the placement groove 31, such as... Figure 1 As shown;

[0041] In one embodiment of the invention, the lifting member 51 includes a bracket 511, which is movable in a vertical direction to have a first state away from the bottom of the pipe and a second state away from the placement slot 31. The bracket 511 is connected to an A drive member 512 for driving its movement.

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

[0043] In one embodiment of the invention, the pusher 52 includes a push plate 521 connected to a B drive member 522 for driving its movement.

[0044] In one embodiment of the present invention, the B driving component 522 includes a slide table 5221, a push plate 521 is mounted on the slide table 5221, and two guide rods 5222 are slidably connected to both ends of the slide table 5221. The two guide rods 5222 are located at the bottom of the placement groove 31 and are fixedly connected to the inner walls of both ends of the support platform 3.

[0045] Compared to directly pushing the pipe fitting onto the placement groove 31 of the support platform 3, lifting the pipe fitting to a certain height separates the contact surfaces between the pipe fitting and the placement groove 31. This helps reduce the resistance encountered during pipe fitting movement and the degree of wear between the pipe fitting and the placement groove 31. It should be noted that after one end of the pipe fitting is lifted, part of its weight acts on the bracket 511, and another part of the weight acts on the contact area between the other end of the pipe fitting and the placement groove 31. The contact area at this point is very small, so the force required to push the pipe fitting is also smaller. However, this can lead to increased wear at this point. Therefore, a method is provided to solve the above problems, specifically:

[0046] The pusher 52 also includes two support rods 523, which are mounted on the side of the push plate 521 near the cutting station 4 via 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 slide table 5221, and the axis of rotation 5122 at the rotatable connection is located on the side away from the plane where the end of the pipe fitting is located. Figure 7 As shown, it should be noted that the purpose of the rotation axis 5122 being located on the side away from the plane where the end of the pipe is located is to ensure that when the push plate 521 rotates, the end of the pipe will not move toward the surface of the placement groove 31, but will separate from the surface of the placement groove 31.

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

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

[0049] In one embodiment of the present invention, the adjusting member 524 includes a slider 5241, a groove 5242 is provided on one side of the push plate 521, the slider 5241 is slidably connected to the groove 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 passes 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 to the top of the push plate 521 and is connected to a rotating handle, the support position of the support rod 523 is adjusted by rotating the threaded rod 5243, during adjustment, the two support rods 523 should be pressed against the bottom of the pipe, so that when the other end of the pipe is lifted, it can be supported by the two support rods 523.

[0050] In one embodiment of the present invention, another mode of movement for the lifting member 51 and the pushing member 52 is provided, specifically:

[0051] The A-drive component 512 includes a disc cam 5121, with a rotating shaft 5122 fixedly connected to one side of the disc cam 5121. A roller 5123 is provided above the disc cam 5121 and abuts against its side. 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-drive frame also includes a horizontally arranged hollow frame 5125. The rotating rod 5124 is located in the middle of the hollow frame 5125, and its other end is rotatably connected to the hollow frame 5125. Two sliding rods 5126 are fixedly connected to both ends of the frame. The sliding rods 5126 are slidably connected to the inner wall of the support platform 3.

[0052] One end of the rotating shaft 5122 is connected to the motor 5127 for driving its rotation. By driving the rotating shaft 5122 to rotate, the disc cam 5121 is driven to rotate, which in turn drives the roller 5123 to move up and down in the vertical direction. This allows the bracket 511 to move up and down. It should be understood that the maximum upward stroke corresponds to the height of the pipe end, and the maximum downward stroke should separate the bracket 511 from the bottom of the pipe so that the pipe can be placed on the placement groove 31.

[0053] The B-drive component 522 includes a cylindrical cam 5223 and a driven rod 5224. The driven rod 5224 abuts against one side of the cylindrical cam 5223. One end of the driven rod 5224 is fixedly installed at one end of the hollow frame 5125, and the axis of the driven rod 5224 is parallel to the axis of the rotation shaft 5122. A ratchet stop 525 is provided between the slide table 5221 and the hollow frame 5125. When the ratchet stop 525 is activated, the slide table 5221 can only move along the pipe conveying direction. The hollow frame 5125... A sliding column 5258 is fixedly installed at one end. The surface of the sliding column 5258 is slidably connected to the inner wall of the support platform 3. A second spring 5257 is provided 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 platform 3 away from the hollow frame 5125. A retaining ring is provided at the end of the sliding column 5258. The other end of the second spring 5257 abuts against one side of the retaining ring.

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

[0055] The ratchet limiting component 525 includes two ratchet plates 5251 disposed on the top of the hollow frame 5125, and ratchet blocks 5252 that limit and cooperate with the two ratchet plates 5251. A movable cavity 5253 is provided in the slide table 5221 for the two ratchet blocks 5252 to slide longitudinally. The tops of the two ratchet blocks 5252 are fixedly connected by the same connecting plate 5254. Two first springs 5255 are installed in the movable cavity 5253. The elastic force of the first springs 5255 acts on the connecting plate 5254 and the two ratchet blocks 5252, so that they have a downward tendency. A pull rod 5256 is fixedly connected to the top of the connecting plate 5254. One end of the pull rod 5256 passes through the slide table 5221 and is slidably connected to the top of the slide table 5221.

[0056] Driven by the cylindrical cam 5223 and in cooperation with the second spring 5257, the follower moves horizontally, thereby moving the hollow frame 5125. When the hollow frame 5125 moves towards the cutting station 4, the ratchet plate 5251 engages with the ratchet block 5252, causing it to move the slide table 5221 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 will not cause the slide table 5221 to move. It should be noted that when the hollow frame 5125 moves away from the cutting station 4, the first spring 5255 should be set to satisfy the following: the ratchet plate 5251 acts on the ratchet block 5252 to contract so that the maximum thrust on the slide table 5221 is not greater than the minimum force required for the slide table 5221 to move along the guide rod 5222.

[0057] In one embodiment of the present invention, the two ratchet blocks 5252 can be configured to move independently, and the teeth of the two ratchet plates 5251 can be staggered, such as... Figure 9 As shown, at this time, the ratchet block 5252 is slidably connected to the connecting plate 5254 on the opposite side. The two first springs 5255 act on the two ratchet blocks 5252 respectively. By offsetting the teeth of the ratchet plate 5251 by a certain distance, the minimum moving distance for the ratchet plate 5251 and the ratchet block 5252 to cooperate is reduced. That is to say, when the two ratchet plates 5251 are basically perfectly symmetrically arranged, the cooperation between the ratchet block 5252 and the ratchet plate 5251 requires at least the movement of two adjacent teeth to ensure that the movement of the ratchet plate 5251 can push the ratchet block 5252. By setting the two ratchet plates 5251 to be offset by a certain distance, this minimum moving distance is reduced. For example, the teeth on the ratchet plate 5251 can be set to be located in the middle position of two opposite teeth of the other ratchet plate 5251 (see...). Figure 10 (The two dashed lines indicate the staggered positions). At this time, the minimum distance will be shortened to half the distance between two adjacent teeth. This makes the distance moved by the pipe fitting more consistent each time it is cut, thereby making the width tolerance of the pipe fitting smaller and improving the dimensional stability of the cutting operation.

[0058] In one embodiment of the present invention, the disc cam 5121 and the cylindrical cam 5223 have a certain engagement method. The disc 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 rotational 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 dashed lines indicate the boundaries between each interval; a is the position corresponding to the disc cam 5121, and b is the position corresponding to the cylindrical cam 5223.) Figure 6During clockwise rotation in the indicated direction (the hollow arrow indicates the position of roller 5123 and driven wheel), the bracket 511 switches from the first interval to the second state, and the pusher 52 does not function; in the second interval, the bracket 511 remains in the second state, and the pusher 52 moves the pipe towards the cutting station 4; in the third interval, the bracket 511 switches back to the first state, and the pusher 52 does not function; in the fourth interval, the bracket 511 remains in the first state, and the pusher 52 does not function (the hollow bracket moves away from the cutting station 4, but due to the ratchet limiter 525, the pusher 52 will not return);

[0059] By integrating the disc cam 5121 and the cylindrical cam 5223, the drive cam can precisely control the movement of the bracket 511 and the pusher 52. Especially when the bracket 511 switches states, it can respond promptly, ensuring that the movement of the pusher 52 is smooth and precise, effectively improving the system's working efficiency and operational accuracy. It also reduces the number of parts, making the overall equipment more compact and easier to install. The integrated design also makes the transmission between the disc cam 5121 and the cylindrical cam 5223 more direct, reducing contact and friction between multiple parts, which helps extend the service life of the equipment and reduce the frequency and cost of maintenance. Since the disc and cylindrical cams 5223 are fixedly connected as one unit, the adjustment and calibration process is also simplified, reducing the complex steps that may be encountered when adjusting each cam individually.

[0060] In one embodiment of the present invention, the clamping member 41 includes a base 411 and a pressure plate 412. The base 411 is also V-shaped and is adapted to the height of the placement groove 31. The pressure plate 412 can move in the vertical direction, so that when the cutting device 2 cuts the pipe, it presses the pipe onto the base 411. After the cutting is completed, the pressure plate 412 moves upward to release the pressing state and moves to a height that does not obstruct the conveying of the pipe. The movement of the pressure plate 412 can be driven by a cylinder, a hydraulic cylinder or an electric telescopic rod, which are existing technologies and will not be described in detail here.

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

[0062] Equipment Phase:

[0063] Place the pipe to be cut in the placement slot 31 of the support table 3, move the slide table 5221 to make the push plate 521 press against the end of the pipe, and then rotate the threaded rod 5243 to adjust the position of the support rod 523 so that the support rod 523 presses against the bottom of the end of the pipe to provide a certain support force. Adjust the position of the pipe 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 parts 41 until the pipe is cut.

[0066] Next, the pressure 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 to move. Specifically, the end of the pipe closest to the cutting station 4 is first lifted to a certain height, making it tilted. At this time, the other end of the pipe 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 tilted pipe towards the cutting station 4. With the setting of the cylindrical cam 5223 and the cooperation of the ratchet limit member 525, the pipe is kept at a certain distance. After the movement, the lifting member 51 descends to make the end of the pipe descend. The pipe will be placed in the placement groove 31 and the clamping member 41 in a horizontal state. The cutting device 2 can be started to complete the cutting here. At the same time, the driving cam continues to rotate, and the hollow support will return to the starting position. The above process will continue in the next cutting, so as to continuously cut the pipe. The cut product is the semi-finished bearing outer ring. The cut semi-finished product can be collected for further processing.

[0067] In one embodiment of the present invention, since debris is generated during the cutting process, some of the debris may remain on the support plane of the base 411 of the clamping member 41. Whether the pipe is pushed directly on the placement groove 31 or the pipe is moved in an inclined posture as in this solution, the presence of debris may cause gaps (blocking between the pipe and the corresponding support plane) at the contact points between the pipe and the support plane and the surface of the placement groove 31, resulting in a certain tilt of the cutting surface during cutting and affecting the stability of the cutting dimensions. In the method of directly pushing the pipe in the placement groove 31, since the pipe is always present at the clamping member 41 near the pipe during operation, the debris at this location is often difficult to clean. Once the debris is large and gets stuck between the pipe and the corresponding support plane during the movement of the pipe, it is easy to cause damage. This can cause deep scratches on the pipe surface or cause the pipe end to warp, which are difficult to eliminate even with the clamp 41. However, by lifting the end of the pipe when it moves, the pipe can be separated from the support plane of the clamp 41. After separation, the debris can be moved away under its own weight. Furthermore, a nozzle (not shown in the figure) can be installed at the clamp 41, facing the support plane. The nozzle is connected to an air source and sprays a certain pressure gas to blow away the debris in the corresponding area, so that the corresponding support plane can be kept clean each time the pipe moves. It should be understood that the support plane refers to the surface of the pipe when it is being cut, the surface of the base 411 of the clamp 41, and the surface of the placement groove 31 near the cutting device 2 (the range that the cutting debris can move to).

[0068] In one embodiment of the present invention, the cutting device 2 further includes a feeding plate 6 disposed at the cutting station 4. After the pipe is cut, when the pipe is raised to a certain height and conveyed to the cutting station 4 by the above-mentioned method of moving the pipe, the end of the pipe to be cut can push the top of the outer ring of the bearing that is standing on the base 411 after cutting, so that it tilts onto the feeding plate 6 and finally slides into the collection box 7.

[0069] The foregoing has only described certain exemplary embodiments of the present invention by way of illustration. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the foregoing drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
