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 have gradually become apparent: First, the bending performance 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 fit with square holes or rectangular slots requires additional adapters, resulting in structural redundancy; to solve the above problems, rectangular shafts came into being. Through non-circular cross-section design, their bending section modulus is significantly improved, and they can withstand greater bending moments under the same material conditions; at the same time, the direct fit characteristics of rectangular shafts with guide grooves, sliders and other parts simplify the structural design and improve space utilization.

[0003] Currently, the machining of rectangular shafts requires the use of a cutting device to create multiple mounting holes or limiting holes on the shaft. Most existing cutting devices utilize advanced laser cutting technology. The metal shaft must first be stably secured to a specially designed cutting device to prevent displacement or shaking during the cutting process, ensuring the precise positioning and dimensional accuracy of the cut holes. Once secured, the laser cutting assembly within the cutting device activates. The high temperature of the laser rapidly melts and vaporizes the material on the metal shaft surface, allowing the cut holes to be made. However, this process inevitably generates waste material that falls into the shaft.

[0004] For example, the Chinese patent document with the announcement number CN110576268B discloses an automated laser tube cutting machine, including a tube storage warehouse, an automatic loading device, a laser tube cutting machine and a tube support mechanism arranged in sequence. The tube storage warehouse transports the tubes to the automatic loading device, and the automatic loading device transports the tubes to the laser tube cutting machine for cutting. The tube support mechanism is used to support the tubes during the processing of the laser tube cutting machine; the laser tube cutting machine includes a tube cutting bed, a front chuck, a rear chuck, a laser cutting head assembly, a laser cutting head mounting seat, a drilling and tapping machine and a control system. The front chuck is arranged on the tube cutting bed, and the rear chuck is slidably connected along the tube cutting bed. The rear chuck can move along the length direction of the tube bed. The drilling and tapping machine passes through two oppositely arranged laser cutting head mounting side plates and is fixedly connected to the laser cutting head mounting seat. The drilling and tapping machine is arranged toward the tube to be cut. The pipe is fixed by the front chuck and the rear chuck, and then when the front chuck and the rear chuck move, the drilling and tapping machine can open holes in different positions of the pipe. The drilling and tapping machine is set on the laser cutting head mounting seat. The automated laser pipe cutting machine can not only cut the pipe, but also drill and tap the cut pipe.

[0005] In the above-mentioned related technologies, holes can be drilled in pipes by using a drilling and tapping machine. However, since the drilling and tapping machine is arranged above the pipe, after the hole is drilled in the pipe, the waste will fall into the pipe under the action of gravity. When multiple holes are opened along the length of the pipe, the waste that falls into the middle of the pipe needs to be removed from the chuck after the hole is drilled. Then the removed pipe is placed vertically, and the waste inside the pipe will fall from the opening at the end of the pipe, thereby achieving the purpose of cleaning the waste. When the pipe is relatively long and heavy, it is inconvenient to stand up the pipe after the hole is drilled. In addition, when both ends of the pipe are in a blocked state, the fallen waste is even more difficult to be cleaned, resulting in the problem of very inconvenient waste cleaning during the entire hole drilling process. Summary of the Invention

[0006] The present application provides a shaft processing device, which aims to solve the problem in the related art that it is inconvenient to clean the waste material inside the shaft.

[0007] The present application provides a shaft processing device that adopts the following technical solution:

[0008] The cutting tool of the present invention is a kind of cutting tool of the present invention, and its cutting tool is a kind of cutting tool of the present invention.

[0009] By adopting the above technical solution, when cutting a hole in a shaft, one of the support assemblies is first placed in the shaft so that the upper support rod abuts against the end face of the shaft, and then the other support assembly is placed below so that the lower support assembly corresponds to the laser cutting assembly. Then, the hydraulic oil in the upper support cylinder tends to flow into the lower support cylinder under the action of gravity. After the corresponding position of the lower support assembly is cut, it makes way for the lower support rod. Then, the upper hydraulic oil flows downward into the lower support cylinder. The hydraulic oil flowing into the lower support cylinder will push the support rod upward, and finally eject the cut waste. At this time, the hydraulic oil in the upper support cylinder drops, and the support rod moves downward under the action of gravity. The support rod moves to the inside of the shaft, and the support cylinder moves downward under the action of gravity. The support cylinder moves to the bottom. At this time, the clamping assembly moves, driving the shaft and the two support assemblies arranged inside the shaft to move simultaneously. During the movement, the ejected material is cleaned to reduce the cut waste from falling into the inside of the shaft, thereby achieving the purpose of convenient waste cleaning. Then, when cutting other positions below, the above steps are repeated.

[0010] Optionally, the laser cutting assembly is provided with a pushing assembly for pushing the ejected waste material off the shaft, the pushing assembly includes a mounting rod provided on the laser cutting assembly and a pushing rod fixed on the mounting rod, and the pushing rod is arranged at an angle.

[0011] By adopting the above technical solution, as the waste is successfully ejected, the support assembly located above 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 to it will play a key role. The clamping assembly uses its unique mechanical structure to achieve a firm and reliable clamping of the shaft, ensuring that the shaft will not deviate or shake during subsequent movement.

[0012] Optionally, a support plate for contacting the cutting 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.

[0013] 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 more effectively.

[0014] 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 both slidably connected to the mounting plate.

[0015] 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.

[0016] 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 cylinder is fixed on the adjustment block, the adjustment screw is passed through the adjustment block, and is threadedly connected to the adjustment block.

[0017] 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 cylinders can be set according to the requirements of the opening, which is more convenient when cutting.

[0018] 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.

[0019] 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.

[0020] Optionally, a counterweight block is fixedly mounted on the bottom of the mounting block.

[0021] By adopting the above technical solution, under the action of the counterweight block, when the upper support plate and the inner wall of the cutting hole are separated, the upper support tube can slide downward faster.

[0022] Optionally, a slide groove is provided on the mounting plate, a T-shaped slider slidably connected in the slide groove is fixedly mounted on the mounting block, and lubricating oil is provided in the slide groove.

[0023] By adopting the above technical solution, the lubricating oil has extremely low viscosity and excellent lubricating properties, and can form a uniform and long-lasting oil film on the contact surface of the T-slider and the slide groove; when the T-slider slides along the slide 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 caused by the friction between rough surfaces; as the friction force is greatly reduced, the sliding of the mounting block on the mounting plate becomes smoother and more efficient, and the lubricating oil can not only reduce friction loss, but also absorb and disperse the heat generated during the movement to a certain extent, preventing material deformation or damage due to local overheating, which enables the mounting block to move on the mounting plate in a more stable and precise manner.

[0024] Optionally, the support tube is provided with a connecting assembly for connecting to the connecting pipe, the connecting assembly includes a mounting tube rotatably connected to the support tube and a connecting ball rotatably connected to the connecting pipe, and the connecting pipe is threadedly connected to the connecting ball.

[0025] By adopting the above technical solution, when the upper support tube moves downward, the mounting tube will rotate on the support tube, reducing the bending of the connecting tube, thereby facilitating the sliding of the support tube.

[0026] Optionally, a plurality of abutment balls are rotatably connected to a side of the mounting plate away from the support plate.

[0027] By adopting the above technical solution, when the support plate below pushes out the waste and the support plate abuts against the inner wall of the cutting hole, the upper support rod and support plate move downward under the action of gravity, and slide on the mounting plate during the movement. When the sliding mounting block abuts against the bottom of the slide groove, it drives the mounting plate to move downward at the same time. Under the action of the abutment ball, the friction force of the mounting plate when moving can be reduced.

[0028] In summary, this application includes at least one of the following beneficial technical effects:

[0029] 1. During the alternating movement of the two support plates, the cut waste will be ejected alternately, and then under the action of hydraulic oil, the purpose of driving the support plates to move without driving can be achieved.

[0030] 2. After the cut waste is ejected, the upper support assembly moves to the bottom, and then the clamping assembly drives the shaft and support assembly to move. During the movement, the push rod pushes the ejected material away from the shaft, thereby achieving the purpose of automatically cleaning the shaft.

[0031] 3. Under the action of the counterweight, when the upper support plate and the inner wall of the cutting hole are separated, the upper support tube can slide downward faster. BRIEF DESCRIPTION OF THE DRAWINGS

[0040] The following combination Figure 1-Figure 7 This application is described in further detail.

[0041] The embodiment of the present application discloses a shaft processing device. Figure 1 and Figure 2 A shaft 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. The laser cutting assembly 1 is used to drill holes in different positions of the shaft or to cut the shaft. When cutting the shaft, the shaft can be cut into a required length by the laser cutting assembly 1; a clamping assembly 3 for fixing the shaft and a limiting assembly 4 for limiting the position of the shaft are arranged on the mounting frame 01; the support assembly 2 is used to eject the cutting waste from the upper surface of the shaft, which can reduce the cutting waste from entering the interior of the shaft, and a pushing assembly 8 for pushing the ejected waste away from the shaft is arranged on the mounting frame 01. When only a hole is opened on the upper surface of the shaft, when the shaft moves, the cutting waste can be pushed away from the shaft under the action of the pushing assembly 8, thereby achieving the purpose of automatic cleaning.

[0042] 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. Then, after the shaft is clamped by the clamping assembly 3, it is passed through the limiting assembly 4 and is below the laser cutting assembly 1. At this time, the shaft is tilted upward, and the laser cutting assembly 1 in this embodiment only cuts holes on the upper surface of the shaft.

[0043] Reference 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 forward and backward on the mounting shell 11, and can thus cut holes or cut off the shaft.

[0044] Reference 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 provided on the sliding frame 31. In addition, a second driving assembly for driving the clamping assembly 3 to move toward the direction close to the laser cutting assembly 1 is provided on the mounting frame 01.

[0045] Reference Figure 1The first drive assembly includes a first drive 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 wrapped around the driving wheel and the driven wheel at the same time. The 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, the specific structure of the three-jaw chuck 32 is not described in detail in this embodiment; the rotation of the first drive motor will drive the driving wheel to rotate, and under the action of the connecting belt, the driving shaft and the driven wheel set on the driving shaft will 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 drill holes on other surfaces of the shaft member, holes can be drilled on different surfaces of the shaft member by rotating the three-jaw chuck 32. At the same time, when no opening is needed, the shaft member can also be cut off, thereby achieving the purpose of both drilling and cutting the shaft member.

[0046] Reference Figure 1 The second driving assembly 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 engaged with each other. When the second driving motor rotates, the driving gear is driven to rotate. Under the action of the driving rack, the entire clamping assembly 3 will move away from or close to the laser cutting assembly 1, making it easier to adjust the position of the shaft.

[0047] Reference Figure 1 The limiting assembly 4 includes a mounting plate 41 fixed on the laser cutting assembly 1 and a plurality of limiting members 42 slidably connected to the mounting plate 41. In this embodiment, four limiting members 42 are provided, and the four limiting members 42 are evenly arranged along the circumference of the mounting plate 41. The two relatively arranged limiting members 42 form a group, and the two groups of limiting members 42 are staggered along the length direction of the shaft; the limiting member 42 includes a limiting frame 421 slidably connected to the mounting plate 41 and a limiting roller 422 rotatably connected to the limiting frame 421. At the same time, a control assembly is provided on the mounting plate 41, and the control assembly is used to drive the four limiting members 42 to approach or move away from each other, thereby limiting the shaft to be cut. Since the limiting roller 422 abuts against the shaft, when the shaft moves, the shaft can drive the limiting roller 422 to rotate, thereby limiting the position of the shaft while adjusting the position of the shaft.

[0048] Reference Figures 1 to 3Inside the shaft, a mounting plate 02 for mounting two support assemblies 2 is located. Mounting plate 02 extends along the length of the shaft, and multiple abutment balls 03 are located at the bottom of mounting plate 02. These abutment balls 03 are spaced apart along the length of the shaft. Under the force of gravity, abutment balls 03 abut the bottom of the shaft, causing mounting plate 02 to move downward in the direction of the shaft's inclination. During the sliding process, abutment balls 03 abut against the bottom wall of the shaft and are simultaneously connected to mounting plate 02 through rotation. This reduces friction during the downward movement of mounting plate 02, ultimately making it easier for mounting plate 02 to slide downward.

[0049] Reference Figures 2 to 6 Two adjusting components 5 are provided on the mounting plate 02. The two adjusting components 5 are arranged on two sides of the mounting plate 02, and the support component 2 is arranged on the adjusting component 5. The two support components 2 correspond to the two adjusting components 5 one by one; the adjusting component 5 includes a mounting block 51 slidably connected to the mounting plate 02, an adjusting block 52 slidably connected to the mounting block 51, and an adjusting screw 53 rotatably connected to the mounting block 51. The mounting block 51 is provided with a mounting groove with an opening facing upward, and the mounting groove is arranged along the length direction of the mounting plate 02. The adjusting block 52 is slidably connected in the mounting groove, and the adjusting screw 53 is passed through the adjusting block 52 to move 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 mounting block 51, and then the position of the adjusting block 52 on the mounting block 51 can be adjusted, so that it is more convenient to adjust the positions of the two support components 2.

[0050] Reference Figures 2 to 6 A T-shaped slider 61 is fixedly mounted on the mounting block 51, and a chute 62 is provided on the mounting plate 02. The chute 62 extends along the length of the mounting plate 02, with one end of the chute 62 extending through the mounting plate 02 and the other end being blocked. The blocked end is positioned downward. The T-shaped slider 61 slides within the chute 62, which is filled with lubricating oil. This lubricating oil reduces friction when the mounting block 51 slides on the mounting plate 02. One end of the chute 62 is penetrated, while the other end of the chute 62 on the mounting plate 02 is open, making it easier for the T-shaped slider 61 to engage within the chute 62.

[0051] When in use, in order to prevent the T-shaped slider 61 from detaching from one end of the slide groove 62, a blocking block 63 is installed at the end of the slide groove 62 where the opening is set. The blocking block 63 is made of elastic rubber material, and the opening at one end of the slide groove 62 can be blocked by squeezing the blocking block 63; in addition, in order to facilitate the blocking block 63 to be inserted into the slide groove 62, a chamfer is provided on the blocking block 63; at the same time, in order to facilitate the sliding of the mounting plate 02 in the shaft, the shaft is set to a hollow structure, which can reduce the weight of the mounting plate 02.

[0052] Reference 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 arranged in the support cylinder 21. In this embodiment, the support cylinder 21 is fixed to the adjustment block 52 by means of bolts. The support rod 22 includes a blocking portion 221 and a supporting portion 222. The blocking portion 221 is slidably connected to the support cylinder 21. The blocking portion 221 is set to an elastic material. The supporting portion 222 is fixed on the blocking portion 221, and the supporting portion 222 extends out of the support cylinder 21. When the support portion 222 extends out of the support cylinder 21, The end thread is connected with an adjusting sleeve 25, which is sleeved on the support part 222. At the same time, a support plate 24 is fixedly installed on the adjusting sleeve 25. The support plate 24 is used to abut the cut waste, and then the hydraulic oil 23 is used to push the support rod 22 to move upward. During the movement of the support rod 22, the support plate 24 will be pushed to move, and the cut waste will be pushed out of the surface of the shaft through the support plate 24, thereby achieving the purpose of facilitating the cleaning of the waste. By setting the support plate 24, the contact area with the waste can be increased, thereby reducing the waste from the cutting hole falling into the inside of the shaft.

[0053] Since two support assemblies 2 are provided, and the two support assemblies 2 are provided on two adjustment assemblies 5, the positions of the two support assemblies 2 can be adjusted by 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 staggered, and then when the support assemblies 2 move, they can not affect each other.

[0054] Reference Figures 2 to 6 A connecting assembly 7 is provided on the support cylinder 21. Since two support cylinders 21 are provided, two connecting assemblies 7 are also provided. A connecting pipe 64 is provided between the two connecting assemblies 7. The hydraulic oil 23 between the two support cylinders 21 is connected through the connecting pipe 64. In this embodiment, the connecting pipe 64 is set as a rubber hose.

[0055] When the support assembly 2 is placed horizontally, the support plates 24 on the two support assemblies 2 are at the same height. Due to the inclined setting of the shaft, when the support assembly 2 is inserted from the opening at one end of the shaft, one support assembly 2 is inside the shaft and the other support assembly 2 is outside the shaft. At this time, the two support assemblies 2 are inclined. When the support assembly 2 is manually installed, the support plate 24 of the lower support assembly 2 is aligned 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, and the side of the upper support plate 24 abuts against the end face of the shaft. Since the side of the upper support plate 24 abuts against the end face of the shaft, the position of the two support assemblies 2 can be limited at this time to prevent the support assemblies 2 from moving downward along the inclined shaft under the action of gravity. When the upper support plate 24 is limited by the end face of the shaft, the lower support cylinder 21 will move to the limit position, and the position corresponding to 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 slide groove 62 , and the T-shaped slider 61 on the upper mounting block 51 abuts against the blocking block 63 of the slide groove 62 .

[0056] Since the hydraulic oil 23 in the upper support cylinder 21 is at a higher position, it tends 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, the top wall of the shaft is not cut, and the position of the lower support plate 24 is limited under the action of the end face of the shaft; at this time, the clamping assembly 3 and the shaft move upward at the same time. During the movement of the shaft, the two support assemblies 2 inside the shaft and the mounting plate 02 will move upward at the same time. When the lower support plate 24 corresponds to the outer laser cutting assembly 1, the shaft stops moving. At this time, the distance between the two support plates 24 is the distance between adjacent cutting holes, and the shaft corresponding to the lower support plate 24 is cut by the laser cutting assembly 1. After the cutting is completed, the lower support plate 24 loses support, and the hydraulic oil 23 in the upper support cylinder 21 will flow through the connecting pipe The component 7 and the connecting pipe 64 enter the support cylinder 21 below. As the hydraulic oil 23 in the lower support cylinder 21 increases, the hydraulic oil 23 in the lower support cylinder 21 will push the support rod 22 and the support plate 24 to move upward. During the movement, the cut waste will be pushed out of the upper surface of the shaft. At the same time, the lower support plate 24 will abut against the inner wall of the cutting hole. As 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 will be flush with the inner top wall of the shaft. Finally, under the action of gravity, the upper support component 2 and the mounting plate 02 will move downward. At this time, the support component 2 moved to the bottom supports the position that needs to be cut later. Repeating the above steps can achieve the purpose of opening a hole on the upper surface of the shaft and facilitate the cleaning of waste.

[0057] Reference Figures 2 to 6 To reduce friction between the support plate 24 and the inner top wall of the shaft, a plurality of rolling balls 241 are rotatably connected to the support plate 24. Hydraulic oil 23 pushes the rolling balls 241 on the support plate 24 against the inner top wall of the shaft, improving the movement of the support plate 24 during its downward movement. To increase the potential energy of the support tube 21's downward movement, a counterweight 04 is fixedly mounted on the mounting block 51. The specific weight of the counterweight 04 can be selected based on actual needs to ensure that the support tube 21 can move downward to the designated position under the action of gravity.

[0058] Reference Figures 2 to 7 The connecting assembly 7 includes a mounting tube 71 rotatably connected to the support tube 21 and a connecting ball 72 rotatably connected to the connecting tube 64. The mounting tube 71 includes a first connecting portion 711 rotatably connected to the support tube 21 and a second connecting portion 712 fixed on the first connecting portion 711. The first connecting portion 711 and the second connecting portion 712 are vertically 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 tube 64 is fixed on the mounting portion 722 and is detachably connected to the mounting portion 722. Since the connecting tube 64 is rotated on the support tube 21 through the mounting tube 71, the mounting tube 71 can be rotated on the support tube 21 during the downward movement of the upper support tube 21, thereby reducing the bending of the connecting tube 64.

[0059] Reference Figures 2 to 7 The pushing assembly 8 includes a mounting rod 81 arranged on the mounting shell 11 and a pushing rod 82 fixed on the mounting rod 81. The mounting rod 81 is arranged in a direction perpendicular to the movement of the shaft. The pushing rod 82 abuts against the upper surface of the shaft, and the pushing rod 82 is arranged at an angle. When the ejected waste and the shaft move upward along the inclined direction of the shaft at the same time, the pushing rod 82 will push the waste to move, so that the waste will automatically detach from the shaft.

[0060] Reference Figures 2 to 7A counterweight 04 is also fixedly mounted 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 downward in an inclined direction. Specifically, the mounting rod 81 moves downward in the mounting housing 11 in a direction perpendicular to the movement of the shaft. Then, under the action of gravity, the push rod 82 abuts against the upper surface of shafts of different sizes, thereby allowing shafts of different sizes to be cleaned. In addition, the push rod 82 can fit more tightly against the upper surface of the shaft. In the initial state, the shaft is not under the push rod 82. Then, during the movement of the shaft, the staff needs to move the push rod 82 upward. When the shaft moves under the push rod 82, the push rod 82 is released. The push rod 82 abuts against the upper surface of the shaft under the action of the counterweight 04. Then, during the upward movement of the shaft, the push rod 82 pushes the waste away from the upper surface of the shaft, thereby achieving the purpose of automatically cleaning the waste.

[0061] The implementation principle of a shaft processing device in an embodiment of the present application is: first, fix the shaft on the clamping assembly 3, then pass the shaft through the limiting assembly 4, and set the shaft at an angle so that the shaft is below the laser cutting assembly 1. Adjust the position between the two support cylinders 21 as needed so that the distance between the two support cylinders 21 is the distance required for the hole to be opened, and then place a support assembly 2 into the shaft, and the side of the other support plate 24 abuts against the end face of the shaft. The upper support assembly 2 is preliminarily positioned under the action of the end face of the shaft. At the same time, due to the inclined setting of the shaft and the mounting plate 02, the other support assembly 2 will move to the bottom under the action of gravity. At this time, one support assembly 2 is above and the other support assembly 2 is below.

[0062] The clamping assembly 3 and the shaft are driven to move by the second driving assembly until the support plate 24 at the bottom corresponds to the laser cutting assembly 1 above, and then the shaft is drilled by the laser cutting assembly 1 above. After the drilling is completed, the cut waste has no pressure on the support plate 24 at the bottom, and 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 to move upward. In the process of the lower support rod 22 moving upward, it will lift the cut waste below, so that the lower support plate 24 will abut against the side wall of the lower cutting hole. At the same time, the hydraulic oil in the upper support cylinder 21 23 is reduced, the upper support rod 22 will move downward under the action of gravity, and the upper support plate 24 will no longer abut against the end face of the shaft. The upper support tube 21 and the support rod 22 will move downward under the action of gravity. During the downward movement, the T-shaped slider 61 will abut against the end face of the slide groove 62, and at this time, it will drive the mounting plate 02 to move at the same time, so that the upper support assembly 2 moves to the bottom, and then the clamping assembly 3 and the shaft are driven to move by the second driving assembly. During the movement of the shaft, the internal support assembly 2 will also move, and under the action of the push rod 82, the ejected waste will be pushed away from the shaft. Under the action of the support plate 24, the waste can be reduced from entering the interior of the shaft, thereby achieving the purpose of automatically cleaning the waste.

[0063] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
