Description

Technical Field

[0001] The present application relates to the technical field of shaft processing, and in particular to a shaft processing device. Background Art

[0002] In mechanical transmission and load-bearing systems, shaft parts are core basic components. Traditional cylindrical shafts are widely used due to their easy processing and uniform stress distribution. However, with the increasing demand of modern industry for lightweight equipment, compact space and adaptability to special working conditions, the limitations of cylindrical shafts are gradually emerging: First, the bending resistance is limited by the moment of inertia of the circular cross-section, which makes it difficult to meet high-load bending scenarios (such as large-scale engineering machinery cantilevers and high-precision linear guides); second, the coordination with square holes or rectangular slots requires additional adapters, resulting in structural redundancy; to solve the above problems, rectangular shafts came into being. Through the non-circular cross-section design, the bending section modulus is significantly improved, and it can withstand greater bending moments under the same material conditions; at the same time, the direct coordination characteristics of the rectangular shaft with guide grooves, sliders and other parts simplify the structural design and improve space utilization.

[0003] At present, in the process of processing rectangular shafts, it is necessary to open multiple mounting holes or limit holes on the shafts through a cutting device. Most of the existing cutting devices use advanced laser cutting technology. In specific operations, the metal shaft must first be stably fixed on a specially designed cutting device to ensure that the shaft will not be displaced or shaken during the cutting process to ensure the position accuracy and size accuracy of the cutting hole. After the fixation is completed, the laser cutting component in the cutting device will be started. Under the high temperature of the laser, the material on the surface of the metal shaft will quickly melt and vaporize, thereby realizing the cutting and opening operation on the surface of the shaft. However, in this process, waste material that is cut off will inevitably be generated and will fall into the inside of the shaft.

[0004] For example, a Chinese patent document with the publication number CN110576268B discloses an automated laser pipe cutting machine, which includes a pipe storage bin, an automatic loading device, a laser pipe cutting machine, and a pipe support mechanism arranged in sequence. The pipe storage bin transports pipes to the automatic loading device, and the automatic loading device transports the pipes to the laser pipe cutting machine for cutting. The pipe support mechanism is used to support the pipes during the processing of the laser pipe cutting machine. The laser pipe cutting machine includes a pipe cutting bed, a front chuck, a rear chuck, a laser cutting head assembly, a laser cutting head mounting seat, a drilling and tapping integrated machine, and a control system. The front chuck is arranged on the pipe cutting bed, and the rear chuck is slidably connected along the pipe cutting bed. The rear chuck can move along the length direction of the pipe bed. The drilling and tapping integrated machine passes through two relatively arranged laser cutting head mounting side plates and is fixedly connected to the laser cutting head mounting seat. The drilling and tapping integrated machine is arranged facing the pipe to be cut. The pipes are fixed by the front chuck and the rear chuck. Then, when the front chuck and the rear chuck move, the drilling and tapping integrated machine can open holes at different positions of the pipes. There is a drilling and tapping integrated machine on the laser cutting head mounting seat. Through the automated laser pipe cutting machine, not only can pipes be cut, but also the pipes to be cut can be drilled and tapped.

[0005] In the above related technology, the drilling and tapping integrated machine can be used to open holes in the pipes. However, since the drilling and tapping integrated machine is arranged above the pipes, after the holes are opened in the pipes, the waste materials will fall into the pipes under the action of gravity. When multiple holes are opened along the length direction of the pipes, the waste materials that fall to the middle position of the pipes need to be removed from the chuck after the holes are opened, and then the removed pipes are placed vertically. The waste materials inside the pipes will fall from the openings at the ends of the pipes, thereby achieving the purpose of cleaning the waste materials. When the pipes are relatively long and heavy, it is not convenient to stand up the pipes after the holes are opened. In addition, when both ends of the pipes are blocked, the fallen waste materials are even more difficult to clean, resulting in the problem that it is very inconvenient to clean the waste materials during the entire hole-opening process. Summary of the Invention

[0006] This application provides a shaft part processing device, aiming to solve the problem that it is inconvenient to clean the waste materials inside the shaft parts in the related technology.

[0007] The shaft part processing device provided by this application adopts the following technical solutions: A shaft machining device includes a mounting frame and a laser cutting assembly arranged on the mounting frame. A clamping assembly and a limiting assembly are arranged on the mounting frame. It also includes two support assemblies arranged inside the shaft. The support assemblies are used to support the cut waste. The heights of the clamping assembly, the limiting assembly, and the laser cutting assembly gradually increase along the moving direction of the shaft, so that the shaft to be cut is inclined. The support assembly includes a support cylinder slidably connected inside the shaft, a support rod slidably connected inside the support cylinder, and hydraulic oil arranged inside the support cylinder. The hydraulic oil is used to push the support rod to move upward. The hydraulic oil in the two support cylinders is communicated through a connecting pipe. When the cutting of the shaft corresponding to the lower support assembly is completed, the hydraulic oil in the upper support cylinder flows downward into the lower support cylinder under the action of gravity, causing the support rod in the lower part to move upward to eject the waste cut below, and the support rod abuts against the inner wall of the cutting hole. The support rod in the upper support cylinder moves downward, and the upper support cylinder moves to the lower part of the lower support assembly under the action of gravity.

[0008] By adopting the above technical solution, when cutting a cutting hole in a shaft, first place one of the support assemblies into the shaft so that the upper support rod abuts against the end face of the shaft. Then the other support assembly is located below, making the lower support assembly correspond to the laser cutting assembly. Then, the hydraulic oil in the upper support cylinder has a tendency to flow downward into the lower support cylinder under the action of gravity. After the position corresponding to the lower support assembly is cut, it serves the purpose of making way for the lower support rod. Then the hydraulic oil in the upper part flows downward into the lower support cylinder. The hydraulic oil flowing into the lower support cylinder will push the support rod to move upward, and finally eject the cut waste. At this time, the hydraulic oil in the upper support cylinder drops, and the support rod will move downward under the action of gravity. The support rod moves into the shaft, and the support cylinder moves downward under the action of gravity. The support cylinder moves to the lowest position. At this time, the clamping assembly moves to drive the shaft and the two support assemblies arranged inside the shaft to move simultaneously. During the movement, the ejected materials are cleaned to reduce the cut waste from falling into the shaft, thereby achieving the purpose of facilitating the cleaning of the waste. Then, when cutting other positions below, repeat the above steps.

[0009] Optionally, a pushing assembly for pushing the ejected waste away from the shaft is arranged on the laser cutting assembly. The pushing assembly includes a mounting rod arranged on the laser cutting assembly and a pushing rod fixed on the mounting rod. The pushing rod is inclined.

[0010] By adopting the above technical solution, as the waste is successfully ejected, the upper support assembly will begin to move toward the lower end of the shaft according to the preset trajectory. When the upper support assembly moves to the designated position below, the clamping assembly closely connected thereto will play a key role. The clamping assembly can firmly and reliably clamp the shaft through its unique mechanical structure, ensuring that the shaft will not deviate or shake during subsequent movement.

[0011] Optionally, a support plate for abutting against the cut waste is provided on the support rod, and one end of the support plate facing away from the support rod is rotatably connected to a rolling ball.

[0012] By adopting the above technical solution, under the action of the support plate, the waste is ejected more stably and the tilting of the waste is reduced. In addition, under the action of the rolling ball, the upper support tube and the support plate move downward under the action of gravity, which reduces the friction between the support plate and the top of the shaft, making the support plate and the support tube slide down better.

[0013] Optionally, each of the support tubes is provided with an adjustment assembly, and the two adjustment assemblies are connected via a mounting plate, so that the two support tubes are slidably connected to the mounting plate.

[0014] By adopting the above technical solution, under the action of the two adjustment components, the two mounting tubes are both slidably connected to the mounting plate, so that the two mounting tubes are more stable when moving.

[0015] Optionally, the adjustment assembly includes a mounting block slidably connected to the mounting plate, an adjustment block slidably connected to the mounting block, and an adjustment screw rotatably connected to the mounting block, the end of the support tube is fixed on the adjustment block, the adjustment screw is passed through the adjustment block, and is threadedly connected to the adjustment block.

[0016] By adopting the above technical solution, rotating the adjusting screw can drive the adjusting block to slide on the mounting block, and then adjust the position of the supporting assembly on the adjusting block, so that the distance between the two supporting tubes can be set according to the requirements of the opening, which is more convenient when cutting.

[0017] Optionally, an adjustment sleeve is fixedly mounted on one end of the mounting plate away from the rolling ball, the adjustment sleeve is mounted on the support rod, and the adjustment sleeve and the support rod are threadedly connected.

[0018] By adopting the above technical solution, when cutting shafts of different sizes, since the adjusting sleeve is threadedly connected to the support rod, the position of the support plate can be adjusted by rotating the support plate, so that the support plate can push out waste in different shafts.

[0019] Optionally, a counterweight block is fixedly mounted on the bottom of the mounting block.

[0020] By adopting the above technical solution, under the action of the counterweight block, when the upper support plate is separated from the inner wall of the cutting hole, the downward sliding speed of the upper support cylinder can be made faster.

[0021] Optionally, a sliding groove is formed in the mounting plate, a T-shaped slider slidably connected in the sliding groove is fixedly mounted on the mounting block, and lubricating oil is provided in the sliding groove.

[0022] By adopting the above technical solution, the lubricating oil has an extremely low viscosity and excellent lubricating performance, and can form a uniform and persistent oil film on the contact surface between the T-shaped slider and the sliding groove; when the T-shaped slider slides along the sliding groove under the drive of an external force, this oil film plays a key isolation role, effectively preventing direct contact between metal surfaces, thereby greatly reducing the resistance generated by the mutual friction of rough surfaces; with the significant reduction of the frictional force, the sliding of the mounting block on the mounting plate becomes smoother and more efficient. The lubricating oil can not only reduce frictional losses, but also absorb and disperse the heat generated during the movement to a certain extent, preventing material deformation or damage caused by local overheating, which enables the mounting block to move on the mounting plate in a more stable and precise manner.

[0023] Optionally, a connection assembly for connecting with the connecting pipe is provided on the support cylinder, and the connection assembly includes a mounting pipe rotatably connected to the support cylinder and a connecting ball rotatably connected to the connecting pipe, and the connecting pipe is threadedly connected to the connecting ball.

[0024] By adopting the above technical solution, during the downward movement of the upper support cylinder, the mounting pipe will rotate on the support cylinder, reducing the situation of the connecting pipe being bent, thereby facilitating the sliding of the support cylinder.

[0025] Optionally, a plurality of abutting balls are rotatably connected to the side of the mounting plate away from the support plate.

[0026] By adopting the above technical solution, when the lower support plate ejects the waste material and the support plate abuts against the inner wall of the cutting hole, the upper support rod and the support plate move downward under the action of gravity, and will slide on the mounting plate during the movement. When the sliding mounting block abuts against the bottom of the sliding groove, it will drive the mounting plate to move downward simultaneously. Under the action of the abutting balls, the frictional force during the movement of the mounting plate can be reduced.

[0027] In summary, the present application includes at least one of the following beneficial technical effects: 1. During the alternating movement of the two support plates, the cut waste materials will be alternately ejected, and then under the action of the hydraulic oil, the purpose of driving the support plate to move without a drive can be achieved.

[0028] 2. After the cut waste is ejected, the upper support assembly moves downward, and then the clamping assembly drives the shaft member and the support assembly to move. During the movement, the push rod pushes the ejected material away from the shaft member, thereby achieving the purpose of automatically cleaning the shaft member.

[0029] 3. Under the action of the counterweight, when the upper support plate is separated from the inner wall of the cutting hole, the downward sliding speed of the upper support cylinder can be made faster. Description of the Drawings

Detailed Embodiments

[0038] The following will Figures 1-7 further describe the present application in detail.

[0039] An embodiment of the present application discloses a shaft part processing device. Refer to Figure 1 and Figure 2 , a shaft part processing device includes a mounting frame 01 arranged on the ground, a laser cutting assembly 1 arranged on the ground, and two support assemblies 2 arranged inside the shaft part. The laser cutting assembly 1 is used to open holes at different positions of the shaft part or to cut the shaft part. When cutting the shaft part, the shaft part can be cut into a required length through the laser cutting assembly 1; a clamping assembly 3 for fixing the shaft part and a limiting assembly 4 for limiting the position of the shaft part are arranged on the mounting frame 01. The support assembly 2 is used to push the cutting waste out of the upper surface of the shaft part, which can reduce the cutting waste from entering the inside of the shaft part. And a pushing assembly 8 for pushing the ejected waste away from the shaft part is arranged on the mounting frame 01. When only holes are opened on the upper surface of the shaft part, when the shaft part moves, under the action of the pushing assembly 8, the cutting waste can be pushed away from the shaft part, achieving the purpose of automatic cleaning.

[0040] In this embodiment, the heights of the clamping assembly 3, the limiting assembly 4, and the laser cutting assembly 1 gradually increase along the length direction of the shaft part. Then, after the shaft part is clamped by the clamping assembly 3, it is passed through the limiting assembly 4 and is located below the laser cutting assembly 1. At this time, the shaft part is arranged obliquely upward, and the laser cutting assembly 1 in this embodiment only cuts holes in the upper surface of the shaft part.

[0041] Refer to Figure 1 , the laser cutting assembly 1 includes a mounting shell 11 arranged on the ground and a laser cutting body 12 arranged on the mounting shell 11. The laser cutting body 12 can move up and down, left and right, and front and back on the mounting shell 11, and thus can cut and open holes in the shaft part or perform a cutting-off process.

[0042] Refer to Figure 1 , the clamping assembly 3 includes a sliding frame 31 slidably connected to the mounting frame 01 and a three-jaw chuck 32 rotatably connected to the sliding frame 31. A first driving assembly for driving the three-jaw chuck 32 to rotate is arranged on the sliding frame 31. In addition, a second driving assembly for driving the clamping assembly 3 to move in a direction close to the laser cutting assembly 1 is arranged on the mounting frame 01.

[0043] Refer to Figure 1, the first driving component includes a first driving motor fixed on the sliding frame 31, a driving wheel fixed on the output shaft of the first driving motor, a driving shaft rotatably connected to the sliding frame 31, a driven wheel fixed on the driving shaft, and a connecting belt wound around the driving wheel and the driven wheel at the same time. One end of the driving shaft away from the driven wheel is fixedly connected to the three-jaw chuck 32. Since the three-jaw chuck 32 belongs to the prior art, in this embodiment, the specific structure of the three-jaw chuck 32 will not be described in detail. When the first driving motor rotates, it drives the driving wheel to rotate. Under the action of the connecting belt, it drives the driving shaft and the driven wheel arranged on the driving shaft to rotate, thereby driving the three-jaw chuck 32 and the shaft member fixed on the three-jaw chuck 32 to rotate. When it is necessary to open holes on other surfaces of the shaft member, the three-jaw chuck 32 can be rotated to open holes on different surfaces of the shaft member. At the same time, when the opening is not required, the shaft member can also be cut off, so as to achieve the purpose of opening holes and cutting off the shaft member.

[0044] Refer to Figure 1 , the second driving component includes a second driving motor fixed on the sliding frame 31, a driving gear fixed on the second driving motor, and a driving rack fixed on the mounting frame 01. The driving rack and the driving gear are meshed. When the second driving motor rotates, it drives the driving gear to rotate. Under the action of the driving rack, the entire clamping component 3 moves away from or close to the laser cutting component 1, so as to facilitate the adjustment of the position of the shaft member.

[0045] Refer to Figure 1 , the limiting component 4 includes a mounting disc 41 fixed on the laser cutting component 1 and a plurality of limiting members 42 slidably connected to the mounting disc 41. In this embodiment, four limiting members 42 are provided, and the four limiting members 42 are evenly arranged along the circumferential direction of the mounting disc 41. Two relatively arranged limiting members 42 are in a group, and the two groups of limiting members 42 are arranged in a staggered manner along the length direction of the shaft member. The limiting member 42 includes a limiting frame 421 slidably connected to the mounting disc 41 and a limiting roller 422 rotatably connected to the limiting frame 421. At the same time, a control component is arranged on the mounting disc 41, and the control component is used to drive the four limiting members 42 to approach or move away from each other, so as to limit the shaft member to be cut. Since the limiting roller 422 abuts against the shaft member, when the shaft member moves, the shaft member can drive the limiting roller 422 to rotate, so as to limit the position of the shaft member and adjust the position of the shaft member at the same time.

[0046] Refer to Figures 1 to 3, an installation plate 02 for installing two support components 2 is arranged inside the shaft part. The installation plate 02 is arranged along the length direction of the shaft part, and a plurality of abutting balls 03 are arranged at the bottom of the installation plate 02. The plurality of abutting balls 03 are arranged at intervals along the length direction of the shaft part. Under the action of gravity, the abutting balls 03 abut against the bottom of the shaft part. Under the action of gravity, the installation plate 02 will move downward along the inclined direction of the shaft part. During the sliding process, since the abutting balls 03 are in contact with the bottom wall of the shaft part, and at the same time the abutting balls 03 are rotatably connected to the installation plate 02, the friction force during the movement of the installation plate 02 can be reduced during the downward movement of the installation plate 02, and finally it is more convenient for the installation plate 02 to slide downward.

[0047] Refer to Figures 2 to 6 , two adjusting components 5 are arranged on the installation plate 02. The two adjusting components 5 are arranged on two sides of the installation plate 02, and the support components 2 are arranged on the adjusting components 5. The two support components 2 and the two adjusting components 5 correspond one by one; the adjusting component 5 includes an installation block 51 slidably connected to the installation plate 02, an adjusting block 52 slidably connected to the installation block 51, and an adjusting screw 53 rotatably connected to the installation block 51. An upward-opening installation groove is formed in the installation block 51, and the installation groove is arranged along the length direction of the installation plate 02. The adjusting block 52 is slidably connected in the installation groove. The adjusting screw 53 passes through and moves on the adjusting block 52 and is threadedly connected to the adjusting block 52. By rotating the adjusting screw 53, the adjusting block 52 can be driven to slide on the installation block 51, and then the position of the adjusting block 52 on the installation block 51 can be adjusted, so that it is more convenient to adjust the positions of the two support components 2.

[0048] Refer to Figures 2 to 6 , a T-shaped slider 61 is fixedly installed on the installation block 51. At the same time, a chute 62 is formed in the installation plate 02. The chute 62 is formed along the length direction of the installation plate 02, and one end of the chute 62 penetrates through the installation plate 02, and the other end is in a blocked state. The blocked end is below. The T-shaped slider 61 is slidably connected in the chute 62. At the same time, lubricating oil is arranged in the chute 62. Under the action of the lubricating oil, the friction force when the installation block 51 slides on the installation plate 02 is smaller. One end of the chute 62 is in a penetrating state. At this time, one end of the chute 62 on the installation plate 02 is in an open state, and then it is convenient for the T-shaped slider 61 to be clamped in the chute 62.

[0049] During use, in order to prevent the T-shaped slider 61 from detaching from one end of the chute 62, a blocking block 63 is installed at the open end of the chute 62. The blocking block 63 is made of elastic rubber material. The open end of the chute 62 can be blocked by squeezing the blocking block 63; in addition, in order to facilitate the insertion of the blocking block 63 into the chute 62, a chamfer is arranged on the blocking block 63; at the same time, in order to facilitate the sliding of the installation plate 02 in the shaft part, the shaft part is arranged as a hollow structure, and at this time the weight of the installation plate 02 can be reduced.

[0050] Referring to Figures 2 to 6 , the support assembly 2 includes a support cylinder 21 fixed on the adjustment block 52, a support rod 22 slidably connected to the support cylinder 21, and hydraulic oil 23 disposed within the support cylinder 21. In this embodiment, the support cylinder 21 is fixed to the adjustment block 52 by bolts. The support rod 22 includes a plugging portion 221 and a support portion 222. The plugging portion 221 is slidably connected within the support cylinder 21. The plugging portion 221 is made of an elastic material. The support portion 222 is fixed to the plugging portion 221 and extends out of the support cylinder 21. An adjustment sleeve 25 is threadedly connected to the end of the support portion 222 extending out of the support cylinder 21. The adjustment sleeve 25 is sleeved on the support portion 222. At the same time, a support plate 24 is fixedly installed on the adjustment sleeve 25. The support plate 24 is used to abut against the cut waste. Then, the hydraulic oil 23 is used to push the support rod 22 upward. During the movement of the support rod 22, the support plate 24 will be pushed to move. The cut waste is pushed out of the surface of the shaft member through the support plate 24, thereby achieving the purpose of facilitating the cleaning of the waste. Through the arrangement of the support plate 24, the contact area with the waste can be increased, thereby reducing the waste from falling into the interior of the shaft member through the cutting hole.

[0051] Since two support assemblies 2 are provided and the two support assemblies 2 are arranged on two adjustment assemblies 5, the positions of the two support assemblies 2 can be adjusted through the adjustment assemblies 5, and then the two support assemblies 2 support two cutting holes at different distances. In this embodiment, the two support assemblies 2 are arranged in a staggered manner, and when the support assemblies 2 move, they will not affect each other.

[0052] Referring to Figures 2 to 6 , a connection assembly 7 is provided on the support cylinder 21. Since two support cylinders 21 are provided, two connection assemblies 7 are also provided. A connection pipe 64 is arranged between the two connection assemblies 7. The hydraulic oil 23 between the two support cylinders 21 is communicated through the connection pipe 64. In this embodiment, the connection pipe 64 is a rubber hose.

[0053] When the support assembly 2 is placed horizontally, the support plates 24 on the two support assemblies 2 are at the same height. Since the shaft member is inclined, when the support assembly 2 is inserted into the opening at one end of the shaft member, one support assembly 2 is inside the shaft member and the other support assembly 2 is outside the shaft member. At this time, the two support assemblies 2 are inclined. When manually installing the support assembly 2, align the support plate 24 of the lower support assembly 2 with the first cutting hole to be cut. Since there is no cutting hole at the corresponding position of the lower support assembly 2, the hydraulic oil 23 cannot flow downward. The hydraulic oil 23 makes the upper surface of the upper support plate 24 flush with the upper surface of the shaft member, and the side surface of the upper support plate 24 abuts against the end surface of the shaft member. Since the side surface of the upper support plate 24 abuts against the end surface of the shaft member, the positions of the two support assemblies 2 can be limited at this time, preventing the support assembly 2 from moving downward along the inclined shaft member under the action of gravity. When the end surface of the shaft member limits the upper support plate 24, the lower support cylinder 21 will move to the limit position, and the corresponding position of the lower support plate 24 is the position where the first cutting hole needs to be opened. At the same time, under the action of gravity, the T-shaped slider 61 on the lower mounting block 51 abuts against the end of the chute 62, and the T-shaped slider 61 on the upper mounting block 51 abuts against the blocking block 63 of the chute 62.

[0054] Since the hydraulic oil 23 in the upper support cylinder 21 is at a relatively high position, there is a tendency to flow into the lower support cylinder 21 under the action of the connecting pipe 64. Since the lower support plate 24 abuts against the top wall of the shaft member and the top wall of the shaft member is not cut, the position of the lower support plate 24 is limited by the end surface of the shaft member. At this time, the clamping assembly 3 and the shaft member move upward simultaneously. During the movement of the shaft member, the two support assemblies 2 and the mounting plate 02 inside the shaft member will move upward simultaneously. When the lower support plate 24 corresponds to the outer laser cutting assembly 1, the shaft member stops moving. At this time, the distance between the two support plates 24 is the distance between adjacent cutting holes. The laser cutting assembly 1 cuts the shaft member corresponding to the lower support plate 24. After cutting is completed, the lower support plate 24 loses support, and the hydraulic oil 23 in the upper support cylinder 21 will enter the lower support cylinder 21 through the connecting assembly 7 and the connecting pipe 64. Since the hydraulic oil 23 in the lower support cylinder 21 increases, the hydraulic oil 23 in the lower support cylinder 21 will then push the support rod 22 and the support plate 24 upward. During the movement, the cut waste will be pushed out of the upper surface of the shaft member, and at the same time, the lower support plate 24 will abut against the inner wall of the cutting hole. Since the hydraulic oil 23 in the upper support cylinder 21 decreases, the upper support rod 22 and the support plate 24 will move downward under the action of gravity, and the upper surface of the upper support plate 24 is flush with the inner top wall of the shaft member. Finally, under the action of gravity, the upper support assembly 2 and the mounting plate 02 will move downward. At this time, the support assembly 2 that has moved downward supports the position to be cut subsequently. By repeating the above steps, the purpose of opening holes on the upper surface of the shaft member and facilitating the cleaning of waste can be achieved.

[0055] Referring to Figures 2 to 6 , in order to reduce the friction between the support plate 24 and the inner top wall of the shaft member, a plurality of rolling balls 241 are rotatably connected to the support plate 24. Then, under the action of the hydraulic oil 23, the rolling balls 241 on the support plate 24 are pushed to abut against the inner top wall of the shaft member. During the downward movement of the support plate 24, the movement effect of the support plate 24 can be better. In order to increase the potential energy of the downward movement of the support cylinder 21, a counterweight 04 is fixedly installed on the mounting block 51. The specific weight of the counterweight 04 can be selected according to actual needs to ensure that the support cylinder 21 can move downward to a specified position under the action of gravity.

[0056] Referring to Figures 2 to 7 , the connecting assembly 7 includes a mounting pipe 71 rotatably connected to the support cylinder 21 and a connecting ball 72 rotatably connected to the connecting pipe 64. The mounting pipe 71 includes a first connecting portion 711 rotatably connected to the support cylinder 21 and a second connecting portion 712 fixed to the first connecting portion 711. The first connecting portion 711 and the second connecting portion 712 are perpendicularly arranged. The connecting ball 72 includes a rotating portion 721 and a mounting portion 722. The rotating portion 721 rotates on the second connecting portion 712. The connecting pipe 64 is fixed to the mounting portion 722 and is detachably connected to the mounting portion 722. Since the connecting pipe 64 rotates on the support cylinder 21 through the mounting pipe 71, during the downward movement of the upper support cylinder 21, the mounting pipe 71 can rotate on the support cylinder 21, thereby reducing the bending of the connecting pipe 64.

[0057] Referring to Figures 2 to 7 , the pushing assembly 8 includes a mounting rod 81 provided on the mounting housing 11 and a pushing rod 82 fixed to the mounting rod 81. The mounting rod 81 is arranged in a direction perpendicular to the movement direction of the shaft member. The pushing rod 82 abuts against the upper surface of the shaft member and is inclined. During the upward movement of the ejected waste material and the shaft member along the inclined direction of the shaft member, the pushing rod 82 will push the waste material to move, so that the waste material can automatically separate from the shaft member.

[0058] Referring to Figures 2 to 7, a counterweight 04 is also fixedly installed on the mounting rod 81. In this embodiment, the mounting rod 81 is slidably connected to the mounting housing 11. Under the action of the counterweight 04, the mounting rod 81 and the push rod 82 tend to move obliquely downward. Specifically, the mounting rod 81 moves downward on the mounting housing 11 along the direction perpendicular to the movement of the shaft member, and then the push rod 82 can abut against the upper surface of shaft members of different sizes under the action of gravity, so as to clean shaft members of different sizes, and in addition, the push rod 82 can be more tightly attached to the upper surface of the shaft member. In the initial state, the shaft member is not under the push rod 82. Then, during the movement of the shaft member, the staff needs to move the push rod 82 upward. When the shaft member moves under the push rod 82, release the push rod 82. The push rod 82 abuts against the upper surface of the shaft member under the action of the counterweight 04. Then, during the process of the shaft member moving obliquely upward, the push rod 82 will push the waste away from the upper surface of the shaft member, so as to achieve the purpose of automatically cleaning the waste.

[0059] The implementation principle of an axial member processing device according to an embodiment of the present application is as follows: First, fix the axial member on the clamping assembly 3, then pass the axial member through the limiting assembly 4, set the axial member obliquely, and place the axial member under the laser cutting assembly 1. Adjust the position between the two support cylinders 21 as required so that the distance between the two support cylinders 21 is the distance for opening a hole. Then, place a support assembly 2 into the axial member, and the side surface of the other support plate 24 abuts against the end surface of the axial member. The upper support assembly 2 is initially positioned under the action of the end surface of the axial member. At the same time, since the axial member and the mounting plate 02 are obliquely arranged, the other support assembly 2 will move downward under the action of gravity. At this time, one support assembly 2 is above and the other support assembly 2 is below.

[0060] Drive the clamping assembly 3 and the shaft member to move through the second drive assembly until the support plate 24 below and the laser cutting assembly 1 above correspond to each other. Then, use the laser cutting assembly 1 above to drill a hole in the shaft member. After the hole drilling is completed, the cut waste has no pressure on the support plate 24 below. Then, the hydraulic oil 23 in the upper support cylinder 21 will enter the lower support cylinder 21 through the connecting pipe 64 under the action of gravity. The hydraulic oil 23 entering the lower support cylinder 21 will push the lower support rod 22 upward. During the upward movement of the lower support rod 22, it will lift the cut waste below, causing the lower support plate 24 to abut against the side wall of the lower cut hole. At the same time, the hydraulic oil 23 in the upper support cylinder 21 decreases, and the upper support rod 22 will move downward under the action of gravity. The upper support plate 24 no longer abuts against the end face of the shaft member. The upper support cylinder 21 and the support rod 22 move downward under the action of gravity. During the downward movement, the T-shaped slider 61 will abut against the end face of the chute 62. At this time, it will drive the mounting plate 02 to move simultaneously, causing the upper support assembly 2 to move to the lowest position. Then, drive the clamping assembly 3 and the shaft member to move through the second drive assembly. During the movement of the shaft member, the internal support assembly 2 will also move. Under the action of the push rod 82, the ejected waste is pushed away from the shaft member. Under the action of the support plate 24, the entry of waste into the interior of the shaft member can be reduced, thereby achieving the purpose of automatically cleaning the waste.

[0061] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereby. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application should be covered within the protection scope of the present application.
