Description

Technical Field

[0001] This invention belongs to the field of shaft turning technology, specifically relating to a shaft part turning device for mechanical equipment research and development prototype preparation. Background Technology

[0002] In the process of developing new mechanical products, a large number of shaft and rod samples are needed for mechanical testing, and many of them are machined for locally hollow shafts with the same outer diameter but different inner diameters.

[0003] Patent publication number CN118404105B relates to the field of shaft machining technology and discloses a turning device for machining shaft parts. The device includes a frame, on which a centering tip and a centering rod are mounted for clamping both ends of a shaft. A centering housing is mounted on the frame, and a centering disk is mounted at the end of the centering housing. The centering tip and the centering disk are coaxially mounted. A drive housing and a drive motor are mounted on the side of the frame away from the centering housing. A drive shaft is rotatably connected to the drive housing and is driven by the drive motor. The centering rod is movably connected to the drive shaft. A clamping seat is mounted on the side of the drive housing adjacent to the centering housing. A chuck for increasing the clamping effect of the shaft is slidably mounted on the clamping seat. The centering rod is driven by the chuck. During the process of the shaft contacting and abutting the centering rod, the chuck moves, achieving the effect of shaft-side clamping. Furthermore, the use of clamping balls reduces wear or adverse effects on the shaft itself.

[0004] In existing technology, the chuck moves during the contact and movement of the shaft with the center rod, thus achieving the effect of shaft-side clamping. However, when machining a long shaft on one side, relying solely on a three-jaw chuck for single-side clamping can cause the shaft to sag due to its own weight if the shaft is suspended too long. Furthermore, since the outer diameter of the shaft is completely uniform, with only the internal hole diameter differing, operators may easily pick up shafts with different inner diameters for machining. Additionally, the large shaft length makes manual loading and correction time-consuming and labor-intensive. Moreover, since the shaft is only stressed at one end, it is prone to tilting and slipping during unloading. Furthermore, when the spray pipe is subjected to external force, the cutting fluid spray may deviate from the shaft cutting point. Summary of the Invention

[0005] The various embodiments of the disclosed technology involve a shaft part turning equipment for the research and development of a mechanical device that can visually remind the operator that the solid block and the inner hole of the shaft part are mismatched when the wrong shaft part is picked, so that the shaft part cannot be properly tightened and the operator can stop work in time to replace the shaft part.

[0006] According to the disclosed embodiments, a turning device for shaft parts used in the research and development of mechanical equipment includes a turning table, a turning frame slidably mounted on the top of the turning table, a three-jaw chuck rotatably mounted on the left side of the turning frame, and an anti-sway component. The anti-sway component includes a shaft member, an adjusting groove, an elastic telescopic rod, an adjusting frame, an adjusting frame, a solid block, a hollow groove, a limiting rod, and a limiting spring. The shaft member is disposed inside the three-jaw chuck. The adjusting frame is fixedly mounted on the top of the turning table. The adjusting frame rotatably penetrates the left and right walls of the adjusting frame. The adjusting groove is formed on the circumferential surface of the adjusting frame. The elastic telescopic rod is fixedly mounted on the left side of the adjusting frame. The solid block is rotatably mounted on the right side of the adjusting frame. The hollow groove is formed on the right side of the solid block. The limiting rod slidably penetrates the left and right walls of the solid block. The limiting spring is disposed between the solid block and the limiting rod. When the turning frame moves to the left, it causes the three-jaw chuck to move to the left. When the three-jaw chuck moves to the left, it causes the shaft member to move to the left. When the shaft member moves to the left, it comes into contact with the solid block.

[0007] In some implementations, a support plate is fixedly installed on the top of the turning table, and a lead screw is rotatably installed between the support plate and the adjusting frame. The lead screw is threadedly connected to the turning frame, and the support plate is used to support the lead screw. A groove is provided on the left side of the shaft member, and a solid block is used to abut against the groove and support the turning part of the shaft member. When the inner wall of the shaft member contacts the solid block, the solid block will seal the inside of the shaft member.

[0008] In some implementations, a rubber gasket is provided on the surface of the solid block to increase the sealing between the solid block and the shaft. A slide rail is fixedly installed on the top of the turning table, and a moving device is provided on the top of the slide rail. When the limiting rod moves to the left, it will compress the limiting spring to generate deformation and store force. At the same time, when the limiting rod moves to the left, it will contact the free end of the elastic telescopic rod and limit the free end of the elastic telescopic rod.

[0009] In some implementations, a fall arrestor and a spray system are also included. The fall arrestor reduces the operator's workload when loading and unloading materials, and the spray system sprays cutting fluid onto the machined portion of the shaft. The fall arrestor includes a load-bearing frame, a support frame, a support roller, a linkage plate, a linkage roller, a fall arrestor rack, a toothed plate, and a gear. The load-bearing frame is fixedly installed on the top of the turning table, the support frame is slidably installed on the inner wall of the load-bearing frame, the support roller is rotatably installed on the top of the support frame, the linkage plate is fixedly installed on the left side of the turning table, the linkage roller is rotatably installed on the left side of the linkage plate, the fall arrestor rack is slidably installed on the left side of the load-bearing frame, the fall arrestor rack is fixedly installed on the inner wall of the fall arrestor frame, the toothed plate is fixedly installed on the front side of the support frame, and the gear is rotatably installed on the left side of the load-bearing frame. When the support frame moves upward, it drives the support roller to move upward, and the upward movement of the support roller contacts the shaft and supports the middle part of the shaft.

[0010] In some implementations, the anti-fall rack meshes with a gear, the toothed plate meshes with a gear, and a spring is provided between the gear and the load-bearing frame. The spring can drive the gear to reset, and the downward movement of the toothed plate to reset will cause the gear to rotate clockwise. The clockwise rotation of the gear will cause the anti-fall rack to move upward, and the upward movement of the anti-fall rack will cause the anti-fall frame to move upward.

[0011] In some implementations, a spring is provided between the support frame and the turning table. The spring can drive the support frame to reset. The bottom right side of the support frame is set as an inclined surface. Setting the bottom right side of the support frame as an inclined surface can reduce the friction when the support frame contacts the linkage roller. The top of the anti-fall frame is set as an arc surface. Setting the top of the anti-fall frame as an arc surface can improve the fit of the shaft member. When the linkage roller moves to the left, it will contact the inclined surface of the support frame and squeeze the support frame. The support frame moves upward under the squeeze of the linkage roller.

[0012] In some implementations, the spray assembly includes a placement frame, an arc-shaped groove, a protective rod, a protective roller, a rotating seat, and a protective groove. The placement frame is fixedly installed on the right side of the adjusting frame. The arc-shaped groove is formed on the circumferential surface of the solid block. The protective rod slides through the bottom of the placement frame. The protective roller is rotatably installed at the bottom of the protective rod. The rotating seat is rotatably installed on the inner wall of the placement frame. The protective groove is formed on the circumferential surface of the rotating seat. When the protective roller moves upward, it will drive the protective rod to move upward. When the protective rod moves upward, it will contact the protective groove and limit the rotation seat.

[0013] In some implementations, the protective roller contacts the arc-shaped groove, a protective spring is provided between the placement frame and the protective rod, the protective spring can drive the protective rod to reset, and a placement hole is provided on the top of the rotating seat, through which the spray pipe can be fixed.

[0014] This invention provides a turning device for shaft parts used in the research and development of mechanical equipment. It has the following beneficial effects: 1. This invention involves moving the shaft to the left to contact the solid block. The solid block supports the inner wall of the shaft, preventing deformation during machining and avoiding uneven machining caused by excessive shaft length and sagging at the machining end. The contact between the solid block and the inner wall of the shaft forms a seal, preventing chips or cutting fluid from entering the hollow cavity of the shaft and reducing post-processing steps.

[0015] 2. This invention allows for the switching of different specifications of solid blocks by manually rotating the adjustment frame after opening the elastic telescopic rod. This allows for the adaptation of shafts with different inner diameters without the need to disassemble and replace the solid blocks. If the wrong shaft is selected, the solid block and the inner hole of the shaft will not match and will not be able to tighten properly. This provides a clear reminder to the operator that the wrong specification has been selected, allowing for timely work stoppage and replacement of the shaft. Furthermore, once the shaft is tightened, the solid block will be locked to prevent the shaft from shaking.

[0016] 3. In this invention, the support roller moves upward to contact the shaft and support the middle part of the shaft. When the turning frame moves to the left, the support roller can be raised to support the middle part of the shaft and improve the machining accuracy of the shaft.

[0017] 4. After the turning process is completed, the fall arrestor moves upward and contacts the shaft, thereby reducing the operator's lifting strength. The fall arrestor is automatically raised through the linkage of the toothed block plate and gears, reducing the operator's lifting load, thereby reducing the operator's labor intensity for lifting materials and reducing the safety hazards caused by the shaft falling.

[0018] 5. In this invention, the upward movement of the protective roller will drive the protective rod to move upward. The upward movement of the protective rod will contact the protective groove and limit the rotation seat. By lifting the protective roller during turning, the orientation of the spray pipe can be fixed, thereby preventing the spray pipe from being deviated due to collision. Attached Figure Description

[0021] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments.

[0022] Please see Figure 1 - Figure 8 One embodiment of the present invention is: a turning device for shaft parts used in the research and development of mechanical equipment, including a turning table 1, a turning frame 2 slidably mounted on the top of the turning table 1, a three-jaw clamp 4 rotatably mounted on the left side of the turning frame 2, and an anti-sway component; the anti-sway component includes a shaft member 5, an adjusting groove 7, an elastic telescopic rod 8, an adjusting frame 9, an adjusting frame 10, a solid block 11, a hollow groove 12, a limiting rod 13, and a limiting spring 14. The shaft member 5 is disposed inside the three-jaw clamp 4. The adjusting frame 9 is fixedly mounted on the top of the turning table 1. The adjusting frame 10 rotatably penetrates the left and right walls of the adjusting frame 9. The adjusting groove 7 is formed on the circumferential surface of the adjusting frame 10. The elastic telescopic rod 8 is fixedly mounted on the left side of the adjusting frame 9. The solid block 11 rotates through the adjusting frame 9. The hollow slot 12 is opened on the right side of the solid block 11, and the limiting rod 13 slides through the left and right walls of the solid block 11. The limiting spring 14 is set between the solid block 11 and the limiting rod 13. The solid block 11 will support the inner wall of the shaft member 5, thereby preventing the shaft member 5 from deforming during machining. At the same time, it will prevent the shaft member 5 from being too long and causing the machining end to droop, resulting in uneven machining. If the wrong shaft member 5 is picked, the solid block 11 and the inner hole of the shaft member 5 will not match and will not be able to be properly tightened. This will visually remind the operator that the wrong specification has been selected, and work should be stopped in time to replace the shaft member 5. Several solid blocks 11 with different diameters are set on the right side of the adjusting frame 9, and multiple solid blocks 11 are correspondingly set with multiple adjusting slots 7.

[0023] A support plate 3 is fixedly installed on the top of the turning table 1. A lead screw 6 is rotatably installed between the support plate 3 and the adjusting frame 9. The lead screw 6 is threadedly connected to the turning frame 2. The support plate 3 is used to support the lead screw 6. A groove is provided on the left side of the shaft member 5. A solid block 11 is used to abut against the groove and support the turning part of the shaft member 5. When the inner wall of the shaft member 5 contacts the solid block 11, the solid block 11 will seal the inside of the shaft member 5. The solid block 11 fits into the inner hole of the shaft member 5 to form a seal, thereby preventing chips or cutting fluid from entering the hollow inner cavity of the shaft member 5 and reducing post-processing steps.

[0024] A rubber gasket is provided on the surface of the solid block 11. The rubber gasket can increase the sealing between the solid block 11 and the shaft member 5. A slide rail is fixedly installed on the top of the turning table 1. A moving device is provided on the top of the slide rail. When the limiting rod 13 moves to the left, it will compress the limiting spring 14 to generate deformation and store force. At the same time, when the limiting rod 13 moves to the left, it will contact the free end of the elastic telescopic rod 8 and limit the free end of the elastic telescopic rod 8. After the shaft member 5 is tightened, it will directly lock the solid block 11 to prevent the shaft member 5 from shaking. The limiting rod 13 passes through the left and right walls of the adjusting frame 10.

[0025] In this embodiment, when the turning frame 2 is in operation: a servo motor is provided on the right side and the output end of the servo motor is fixedly connected to the three-jaw chuck 4; a drive motor is provided on the right side of the support plate 3 and the output end of the drive motor is fixedly connected to the lead screw 6; after the shaft 5 is placed into the three-jaw chuck 4, the three-jaw chuck 4 is started to clamp the shaft 5; at the same time, the drive motor operates to drive the lead screw 6 to rotate; the rotation of the lead screw 6 will drive the turning frame 2 to move to the left; the movement of the turning frame 2 to the left will drive the three-jaw chuck 4 to move to the left. The movement of the three-jaw chuck 4 to the left will cause the shaft 5 to move to the left. The shaft 5 will then contact the solid block 11, which will support the inner wall of the shaft 5. After the shaft 5 contacts the solid block 11, the servo motor will be activated to rotate the three-jaw chuck 4. The rotation of the three-jaw chuck 4 will then rotate the shaft 5, which in turn will rotate the solid block 11. A turning device is mounted on the top of the mobile device. When the shaft 5 rotates, the mobile device will move the turning device forward. When the shaft 5 is moved forward, it will be turned with the rotating shaft 5. When different inner diameter shafts 5 need to be machined, the free end of the elastic telescopic rod 8 is manually pushed upward to disengage from the adjustment frame 10. Then, the adjustment frame 10 is manually rotated to drive the solid block 11 to rotate, thereby switching between solid blocks 11 of different diameters to fit shafts 5 with different inner diameters. When the inner wall of the shaft 5 is in contact with the solid block 11, the solid block 11 will seal the inside of the shaft 5 to prevent turning chips from entering the inside of the shaft 5. Simultaneously, when the shaft member 5 moves to the left to prepare for machining, it will contact the limiting rod 13 and squeeze the limiting rod 13 to move to the left. The movement of the limiting rod 13 to the left will squeeze the limiting spring 14 to deform and store force. At the same time, the movement of the limiting rod 13 to the left will contact the free end of the elastic telescopic rod 8 and limit the free end of the elastic telescopic rod 8, thereby preventing the solid block 11 from loosening during turning and causing the shaft member 5 to shake. If the wrong shaft member 5 is picked up, the solid block 11 and the inner hole of the shaft member 5 will not match and will not be able to tighten properly.

[0026] Please see Figure 1 - Figure 8 Based on the above embodiments, another embodiment of the present invention further includes a fall protection component and a spraying component. The fall protection component is used to reduce the intensity of loading and unloading by the operator, and the spraying component is used to spray cutting fluid onto the machined part of the shaft member 5. The fall protection component includes a load-bearing frame 151, a support frame 152, a support roller 153, a linkage plate 154, a linkage roller 155, a fall protection frame 156, a fall protection rack 157, a toothed plate 158, and a gear 159. The load-bearing frame 151 is fixedly installed on the top of the turning table 1, the support frame 152 is slidably installed on the inner wall of the load-bearing frame 151, and the support roller 153 is rotatably installed on the support frame. At the top of 152, the linkage plate 154 is fixedly installed on the left side of the turning frame 2, the linkage roller 155 is rotatably installed on the left side of the linkage plate 154, the fall arrestor 156 is slidably installed on the left side of the load-bearing frame 151, the fall arrestor rack 157 is fixedly installed on the inner wall of the fall arrestor 156, the toothed plate 158 is fixedly installed on the front side of the support frame 152, and the gear 159 is rotatably installed on the left side of the load-bearing frame 151. When the support roller 153 moves upward, it will abut against the shaft member 5 and support the middle part of the shaft member 5. When the turning frame 2 moves to the left, the support roller 153 can be raised, thereby supporting the middle part of the shaft member 5 and improving the machining accuracy of the shaft.

[0027] The anti-fall rack 157 meshes with the gear 159, and the toothed plate 158 meshes with the gear 159. A spring is installed between the gear 159 and the load-bearing frame 151. The spring can drive the gear 159 to reset. The downward movement of the toothed plate 158 to reset will drive the gear 159 to rotate clockwise. The clockwise rotation of the gear 159 will drive the anti-fall rack 157 to move upward. The upward movement of the anti-fall rack 157 will drive the anti-fall frame 156 to move upward. The anti-fall frame 156 is automatically raised through the linkage of the toothed plate 158 and the gear 159, reducing the load on the operator and thus reducing the labor intensity of the operator when unloading materials.

[0028] A spring is installed between the support frame 152 and the turning table 1. The spring can drive the support frame 152 to reset. The bottom right side of the support frame 152 is set as an inclined surface. The inclined surface of the bottom right side of the support frame 152 can reduce the friction when the support frame 152 contacts the linkage roller 155. The top of the fall arrestor 156 is set as an arc surface. The arc surface of the top of the fall arrestor 156 can fit the shaft member 5. When the linkage roller 155 moves to the left, it will contact the inclined surface of the support frame 152 and squeeze the support frame 152. The support frame 152 moves upward under the squeeze of the linkage roller 155, reducing the safety hazard caused by the shaft member 5 falling.

[0029] The spray assembly includes a placement frame 161, an arc-shaped groove 162, a protective rod 163, a protective roller 164, a rotating seat 166, and a protective groove 167. The placement frame 161 is fixedly installed on the right side of the adjusting frame 9. The arc-shaped groove 162 is opened on the circumferential surface of the solid block 11. The protective rod 163 slides through the bottom of the placement frame 161. The protective roller 164 is rotatably installed on the bottom of the protective rod 163. The rotating seat 166 is rotatably installed on the inner wall of the placement frame 161. The protective groove 167 is opened on the circumferential surface of the rotating seat 166. By lifting the protective roller 164 during turning, the orientation of the spray pipe can be fixed, thereby preventing the spray pipe from being offset due to collision. After the turning is completed, the servo motor can drive the shaft 5 to rotate to the initial position, ensuring that the protective rod 163 falls back and unlocks.

[0030] The protective roller 164 contacts the arc groove 162. A protective spring 165 is provided between the placement frame 161 and the protective rod 163. The protective spring 165 can drive the protective rod 163 to reset. The top of the rotating seat 166 has a placement hole, through which the spray pipe can be fixed. During the turning process, the shaft member 5 will drive the solid block 11 to rotate quickly. The rapid rotation of the solid block 11 causes the protective roller 164 to be pushed up again before it resets downward, thereby preventing the protective roller 164 from continuously jumping up and down on the outer circle of the solid block 11. In addition, the protective rod 163 is long, and even a slight drop can continuously limit the rotation seat 166.

[0031] In this embodiment, when the turning frame 2 moves to the left, it will cause the linkage plate 154 to move to the left. The linkage plate 154 moving to the left will cause the linkage roller 155 to move to the left. The linkage roller 155 moving to the left will contact the inclined surface of the support frame 152 and squeeze the support frame 152. The support frame 152 moves upward under the squeeze of the linkage roller 155. The upward movement of the support frame 152 will stretch the spring and cause it to deform. At the same time, the upward movement of the support frame 152 will cause the support roller 153 to move upward. The upward movement of the support roller 153 will abut against the shaft member 5 and support the middle part of the shaft member 5. After the turning process is completed, the turning frame 2 moves to the right to reset, which will cause the linkage plate 154 to move to the right. The linkage plate 154 moves to the right, which will cause the linkage roller 155 to move to the right. The linkage roller 155 moves to the right and will disengage from the support frame 152, causing the support frame 152 to move downward to reset under the elastic force of the spring. The downward reset of the support frame 152 will cause the toothed block plate 158 to move downward to reset. The downward reset of the toothed block plate 158 will cause the gear 159 to rotate clockwise. The clockwise rotation of the gear 159 will cause the anti-fall rack 157 to move upward. The upward movement of the anti-fall rack 157 will cause the anti-fall frame 156 to move upward. The upward movement of the anti-fall frame 156 will contact the shaft member 5, thereby reducing the operator's loading strength and reducing the possibility of the shaft member 5 falling directly.

[0032] A spraying device is installed on the left side of the adjusting frame 9. A spraying pipe is installed between the spraying device and the rotating seat 166. When the solid block 11 rotates, it will contact the protective roller 164 and squeeze the protective roller 164 to move upward. The upward movement of the protective roller 164 will squeeze the protective spring 165 to deform and store force. At the same time, the upward movement of the protective roller 164 will drive the protective rod 163 to move upward. The upward movement of the protective rod 163 will contact the protective groove 167 and limit the rotating seat 166, thereby preventing the rotation of the rotating seat 166 during the turning operation from causing the spraying direction of the cutting fluid to deviate from the turning point. After the turning operation is completed, the solid block 11 returns to its initial position, causing the protective rod 163 to move downward and reset under the elastic force of the protective spring 165. The downward movement of the protective rod 163 will disengage from the protective groove 167 and release the limit on the rotating seat 166.

[0033] The above description is merely a preferred embodiment of this application, but the scope of protection of this application is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this application, based on the technical solution and application concept of this application, should be included within the scope of protection of this application.
