Technical Field

[0001] The invention relates to the technical field of shaft body processing equipment, and in particular to a hydraulic shaft body processing positioning device. Background Art

[0002] With the continuous advancement of mechanical manufacturing technology, the requirements for workpiece clamping are also increasing. The pursuit of convenient operability, precise positioning ability, efficient time management, multifunctionality of tooling (that is, a set of tooling can be applied to multiple processing needs), wide general adaptability, and ensuring the safety and efficiency of the operation process have become the core elements of tooling design in the field of mechanical processing. Tooling, as an indispensable part of the mechanical manufacturing industry, its performance and quality are directly related to processing efficiency and product quality.

[0003] In the current processing practice for hydraulic shafts, workpiece positioning is a key link. Traditional practices generally rely on positioning pins to achieve precise positioning of the workpiece.

This manual positioning method is not only time-consuming, but also the accuracy is limited by the skills and experience of the operator, which may affect the accuracy and efficiency of subsequent processing. Once the position of the workpiece is manually confirmed to be correct and aligned with the machine tool processing output end, the mechanical processing process can be started to perform cutting, grinding or other forms of processing operations. However, in the process of using the prior art, after the processing of one end of the shaft body is completed, the shaft body needs to be removed first, and then the direction is turned, and the other end of the shaft body is aligned with the machine tool output end for subsequent processing.

[0027] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0028] Example 1

[0029] Reference Figure 1-3 A hydraulic shaft body processing and positioning device comprises a bearing base 1, and a machine tool processing part 2 fixed at one end of the top of the bearing base 1, a processing head 3 is arranged on one side of the machine tool processing part 2, a support plate 4 is installed above the bearing base 1, a vertical frame 5 is fixed on the top of the support plate 4, a processing positioning mechanism is installed between the support plate 4 and the vertical frame 5, the processing positioning mechanism is used to fix the hydraulic shaft body, the processing positioning mechanism comprises a driving assembly and a force assembly, the driving assembly is installed on the top of the support plate 4, and the force assembly is installed on the inner side of the driving assembly.

[0030] The driving assembly includes a first motor 6, a bearing seat 7, a worm 8 and a fan-shaped worm gear 9. The first motor 6 is fixed at one end of the top of the support plate 4. Two bearing seats 7 are fixed to the top of the support plate 4 and close to the first motor 6. A worm 8 is rotatably connected between the two bearing seats 7. The output end of the first motor 6 passes through one of the bearing seats 7 and is fixed to the worm 8. The outer side of the worm 8 is meshed with a fan-shaped worm gear 9. When the first motor 6 is started, the output end of the first motor 6 drives the worm 8 to mesh with the fan-shaped worm gear 9 to rotate, thereby causing the multiple telescopic cylinders 14 to push the shaft body to move toward a position away from the center of the fixed cylinder 11 until the multiple telescopic cylinders 14 release the fixation of the shaft body.

[0031] A fixing cylinder 11 is fixed to the top of the stand 5, and both ends of the fixing cylinder 11 are rotatably connected with docking rings 10. The inner side of the fan-shaped worm gear 9 is fixed to one of the docking rings 10, and the two docking rings 10 are fixed by a locking tension rod 12. A fixing annular protrusion is provided on the outer side of the fixing cylinder 11, and the fixing annular protrusion is rotatably connected to the docking ring 10 to prevent the docking ring 10 from detaching from the outside of the docking ring 10.

[0032] The force-generating assembly includes a first rotating protrusion 13, a telescopic cylinder 14, a second rotating protrusion 15 and a movable rod 16. A plurality of first rotating protrusions 13 are evenly and rotatably connected on one side of the docking ring 10, and a telescopic cylinder 14 is fixed on the inner side of the first rotating protrusion 13. A plurality of second rotating protrusions 15 are evenly and rotatably connected on both ends of the fixed cylinder 11, and a movable rod 16 is fixed on the inner side of the second rotating protrusion 15. The movable rod 16 is slidably connected to the inner side of the telescopic cylinder 14, and a cavity is opened on the inner side of the telescopic cylinder 14, and the cavity is slidably connected to the movable rod 16.

[0033] The outer sides of the telescopic cylinders 14 are all sleeved with rubber sleeves, and the outer sides of the rubber sleeves are all provided with anti-skid patterns. When multiple telescopic cylinders 14 position and fix the center of the shaft body, the rubber sleeves can increase the friction between the telescopic cylinders 14 and the shaft body, and can also provide buffering protection.

[0034] Example 2

[0035] Embodiment 1 is further optimized, specifically, as Figure 4-6 As shown, a flip positioning mechanism is installed between the bearing base 1 and the support plate 4, and the flip positioning mechanism is used to adjust the position of the support plate 4. The flip positioning mechanism includes a force-applying component and a carrying component. A frame 17 is fixed to the top of the bearing base 1 and one end away from the machine tool processing part 2. The inner side of the frame 17 is equipped with a force-applying component, and the inner side of the force-applying component is equipped with a carrying component.

[0036] The force-applying assembly includes a second motor 18, a swing arm 19, a sleeve column 20, a transmission force guide frame 21, a fan-shaped toothed disc 23, a second-order transmission column 24 and a force guide gear 25. The second motor 18 is fixed to the bottom of the frame 17, and the output end of the second motor 18 passes through the frame 17 and is fixed with a swing arm 19. The top of the swing arm 19 is fixed with a sleeve column 20. The outer side of the sleeve column 20 is slidably connected with the transmission force guide frame 21. One end of the transmission force guide frame 21 is rotatably connected with a matching support shaft 22, and the matching support shaft 22 is fixed to the frame 17. The outer side of the matching support shaft 22 and the position above the transmission force guide frame 21 is rotatably connected with a fan-shaped toothed disc 23. The bottom of the fan-shaped toothed disc 23 is fixed with a second-order transmission column 24. The second-order transmission column 24 and the transmission force guide frame 21 The inner side is slidingly connected, and one side of the fan-shaped toothed disk 23 is meshed with a guide gear 25. When the second motor 18 is started, the output end of the second motor 18 drives the swing arm 19 to push the transmission guide bar frame 21 to rotate through the sleeve column 20, so that the transmission guide bar frame 21 pushes the second-order transmission column 24 to rotate, so that the fan-shaped toothed disk 23 meshes with the guide gear 25 to rotate, and the guide gear 25 drives the vertical shaft 26 and the docking mounting plate 28 to rotate synchronously. When the fan-shaped toothed disk 23 rotates half of its own amplitude, the second motor 18 is controlled to stop rotating. At this time, the guide rail 29 flips half a circle, so that the other end of the shaft body in the fixed cylinder 11 corresponds to the position of the processing head 3, and then the electric module 30 is started to control the distance between the shaft body and the processing head 3.

[0037] The mounting assembly includes a vertical shaft 26, a mounting frame 27, a docking mounting plate 28, a guide rail 29 and an electric module 30. The vertical shaft 26 is fixed to the top of the guide gear 25. The outer side of the vertical shaft 26 is rotatably connected to the mounting frame 27. The mounting frame 27 is fixed to the frame 17. The top of the vertical shaft 26 is fixed with a docking mounting plate 28. The top of the docking mounting plate 28 is fixed with a guide rail 29. The top of the guide rail 29 is provided with an electric module 30, which is fixed to the support plate 4. When the shaft body is positioned and fixed, the electric module 30 is started, so that the electric module 30 drives the support plate 4 to move along the outer side of the guide rail 29 until the shaft body contacts the processing head 3, which is convenient for subsequent processing operations.

[0038] From the above, we can know that:

[0039] The present invention is directed to a technical problem: In the current processing practice for hydraulic shafts, workpiece positioning is a key link. Traditional practices generally rely on positioning pins to achieve precise positioning of the workpiece. This process often requires manual intervention by the operator to ensure that the center of the workpiece is accurately aligned with the machine tool processing output end through visual judgment and manual adjustment. This manual positioning method is not only time-consuming, but also the accuracy is limited by the skills and experience of the operator, which may affect the accuracy and efficiency of subsequent processing. Once the position of the workpiece is manually confirmed to be correct and aligned with the machine tool processing output end, the mechanical processing process can be started to perform cutting, grinding or other forms of processing operations. However, in the process of using the prior art, after the processing of one end of the shaft body is completed, the shaft body needs to be removed first, and then the direction is turned, and the other end of the shaft body is aligned with the machine tool output end for subsequent processing. The operation is time-consuming and labor-intensive; the technical solutions of the above-mentioned embodiments are adopted. At the same time, the implementation process of the above-mentioned technical solution is:

[0040] The electrical components in this device are all existing technologies, and their models are only one of them. As long as the electrical components can achieve the purpose of this device, they can be used. All electrical components in the device are connected to their adapted power supplies through wires, and appropriate controllers should be selected according to actual conditions to meet control requirements. The specific connection and control sequence should refer to the following working principle, and the electrical connection between the electrical components is completed in the working sequence. The detailed connection means are well-known technologies in the art. The following mainly introduces the working principle and process, and no longer explains the electrical control;

[0041] The device is moved to the designated area, and then the device is electrically connected to the external power supply. First, the shaft body is placed on the inner side of the fixed cylinder 11, and then the first motor 6 is started. The output end of the first motor 6 drives the worm 8 to engage the fan-shaped worm gear bar 9 to rotate, so that the fan-shaped worm gear bar 9 drives one of the docking rings 10 to rotate. Because the two docking rings 10 are fixed by the locking and tightening rod 12, the docking ring 10 is rotatably connected to the fixed cylinder 11, the fixed cylinder 11 is fixed to the stand 5, the first rotating protrusion 13 is rotatably connected to the docking ring 10, the second rotating protrusion 15 is rotatably connected to the fixed cylinder 11, and the telescopic cylinder 14 is slidably connected to the movable rod 16. Therefore, when the docking ring 10 drives the first rotating protrusion 13 to rotate, since the movable rod 16 is slidably connected to the telescopic cylinder 14, the movable rod 16 can be continuously retracted into the telescopic cylinder 14, so that multiple telescopic cylinders 14 push the shaft body to move toward a position close to the center of the fixed cylinder 11, until multiple telescopic cylinders 14 position and fix the shaft body, so that the shaft body is aligned with 3, which is convenient for subsequent precise processing.

[0042] Through the above configuration, the present application can certainly solve the above technical problems and achieve the following technical effects:

[0043] The present invention realizes automatic flipping and repositioning of the shaft body during the processing process through the structural design of the processing positioning mechanism and the flipping positioning mechanism, allowing the shaft body to be automatically flipped to the other end without human intervention after completing the processing of one end, and accurately aligning the processing head 3 of the machine tool processing part 2, so as to seamlessly connect to the next stage of processing, which not only significantly reduces the time waste and labor cost in the processing process, but also greatly improves the processing accuracy and efficiency, and opens up a new way for efficient and high-precision processing of hydraulic shaft bodies.
