Description

Technical Field

[0001] The utility model belongs to the technical field of gear shaft processing, and in particular relates to a gear shaft repairing device. Background Art

[0002] A gear shaft refers to a mechanical part that supports rotating parts and rotates with them to transmit motion, torque or bending moment. It is generally in the shape of a metal round rod, and each section can have different diameters. The parts that perform rotary motion in the machine are installed on the shaft. During use, the radial surface of the gear shaft is prone to circumferential wear due to the influence of the use environment. When the gear shaft surface wears and consumes a lot, it will have an adverse effect on the movement of parts on the shaft. However, the gear shaft still has a certain use value at this time, so it needs to be repaired for long-term use. At present, the gear shaft repair process requires grinding and polishing. Most of them are done manually, and only a small part uses semi-automatic equipment to complete the grinding and polishing.

[0003] As patent application number CN202221456166.0, a gear shaft repair device includes a bracket supported at both ends of the gear shaft, a support mechanism arranged on the lower side of the middle end of the gear shaft, and a grinding mechanism arranged on the support mechanism, wherein the support mechanism includes a sliding seat, a support assembly, and a linear drive member for driving the support assembly to slide along the axial direction of the gear shaft; the grinding mechanism includes two C-shaped slide rails, a C-shaped fixed plate slidably connected to the C-shaped slide rails, a plurality of grinding assemblies, and a reciprocating drive assembly for driving the C-shaped fixed plate to slide back and forth, the C-shaped slide rails and the C-shaped fixed plate are both annular with a notch for the gear shaft to enter and exit, and the grinding assembly includes a grinder for grinding the gear shaft. The utility model has the effect of improving the problems in the prior art that the handheld grinder used to grind the worn parts of the gear shaft has a large grinding intensity, high labor intensity, low grinding efficiency, and affects the health of the staff.

[0004] The prior art realizes automatic grinding and repair of the outer surface of the gear shaft through the settings of a bracket, a grinding assembly, and a driving part, but there are still certain shortcomings: when the worn surface of the gear shaft is ground and repaired, the entire outer cylindrical surface near the repair point needs to be ground, so a setting that can support and rotate the entire gear shaft is required. The prior art only completes the placement of the gear shaft through the bracket, and cannot ensure that the gear shaft can rotate stably, which is not convenient for the repair of the gear shaft. Utility Model Content

[0005] In order to overcome the deficiencies of the prior art, the utility model provides a gear shaft repairing device.

[0006] The utility model adopts the arrangement of a three-jaw chuck, an anti-skid pad, a hard clamping block and a hard inner rod, so that one end of the gear shaft can not only obtain a large-area anti-wear clamping treatment but also obtain a hard clamping fixation at multiple points, and cooperates with multiple extensions and multi-point supports at the other end, so that the gear shaft is not only easy to install but also can rotate stably during repair, thereby improving the repair quality of the gear shaft.

[0007] In order to achieve the above-mentioned purpose, the utility model provides the following technical solutions: a gear shaft repair device, including an operating table, a fixed plate, a fixed plate fixedly arranged on one side of the upper end face of the operating table, a three-jaw chuck rotatably arranged on the end face of the fixed plate, a plurality of claws evenly slidingly arranged along the circumferential direction on the three-jaw chuck, each of the claws is provided with a detachable connection block, a non-slip pad made of soft metal is arranged on the end face of the connection block, a plurality of non-slip grooves are arranged on the arc surface of the non-slip pad, a plurality of hard clamping blocks are arranged on the non-slip pad between the plurality of non-slip grooves, a movable plate is slidably arranged on one side of the operating table, and a jacking tube is arranged on one side of the movable plate. The non-slip pad made of soft metal and the hard clamping block can effectively clamp and fix one end of the gear shaft.

[0008] Preferably, a screw driver is arranged on the end surface of the operating table, a first driving motor for driving is arranged at one end of the screw driver, a slide is slidably arranged on the screw driver, and a movable plate is connected to the end surface of the slide.

[0009] Preferably, a pushing cylinder is provided on the end surface of the movable plate, and the output end of the pushing cylinder is rotatably connected to a jacking tube.

[0010] Preferably, each of the claw end surfaces is provided with a stepped groove, and the stepped groove is provided with a plurality of mounting holes that cooperate with the connection block. The step groove enables one end of the connection block to abut against the stepped surface of the step groove, thereby improving the fixing effect of the connection block.

[0011] Preferably, anti-skid pads are provided on both side end surfaces of each of the claws, so that the vibration transmitted to the connecting block can be absorbed in time, thereby ensuring the stability of one end of the gear shaft.

[0012] Preferably, a plurality of hard inner rods are evenly arranged on the end surface of the jacking tube in the circumferential direction, and a conical jacking block is arranged outside each of the hard inner rods. The arrangement of the hard inner rods and the conical jacking block can extend the support distance for one end of the gear shaft.

[0014] In summary, compared with the prior art, the beneficial effects of this solution are:

[0015] The utility model arranges the connecting block and the claw as well as the anti-skid pad and the hard clamping block, so that one end of the gear shaft can not only obtain a large-area lossless clamping and centering treatment, but also obtain hard clamping and fixing at multiple points, so that the gear shaft can be effectively fixed and the anti-skid pad can be easily replaced after long-term use, which effectively improves the applicability of the equipment.

[0016] The utility model arranges the jacking tube, the hard inner rod and the conical jacking block so that both ends of the gear shaft can be quickly clamped and fixed. Not only can the supporting distance of the other end of the gear shaft be extended, but also a good supporting effect can be guaranteed, so that the gear shaft can be repaired stably.

[0027] In order to enable those skilled in the art to better understand the solution of the present invention, the technical solution in the embodiment of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiment of the present invention. Embodiment 1:

[0028] refer to Figure 1-10A gear shaft repair device comprises an operating table 10 and a fixed plate 11. The fixed plate 11 is fixedly arranged on one side of the upper end surface of the operating table 10. A three-jaw chuck 12 is rotatably arranged on the end surface of the fixed plate 11. A plurality of claws 20 are uniformly and slidably arranged on the three-jaw chuck 12 along the circumferential direction. A detachable connecting block 23 is arranged on each claw 20. A non-slip pad 25 made of soft metal is arranged on the end surface of the connecting block 23. A plurality of non-slip grooves 26 are arranged on the arc surface of the non-slip pad 25. A plurality of hard clamping blocks 27 are arranged on the non-slip pad 25 between the plurality of non-slip grooves 26. A movable plate 13 is slidably arranged on one side of the operating table 10. A jacking tube 18 is arranged on one side of the movable plate 13.

[0029] The fixed plate 11 is fixedly arranged at one end of the upper end surface of the operating table 10. The three-jaw chuck 12 is a prior art that can be driven mechanically or hydraulically. This article will not elaborate on it in detail. The three-jaw chuck 12 can be rotated as a whole, and can automatically complete the centering clamping process of the gear shaft in conjunction with multiple jaws 20. The arc surface of the anti-skid pad 25 at one end of the connecting block 23 outside each jaw 20 is expanded outward, which can increase the clamping surface and improve the clamping effect. The multiple anti-skid grooves 26 on the arc surface are all V-shaped, which can effectively increase the clamping friction and provide clamping stability. In this relationship, the anti-skid pad 25 is made of soft metal material to avoid clamping damage. Multiple hard clamping blocks 27 are made of hard metal material and embedded in the arc surface of the anti-skid pad 25. The outer end surface of the hard clamping block 27 is provided with anti-skid particles. When the anti-skid pad 25 is clamped as a whole, multiple points of hard support and fixation can be formed on the outer cylindrical surface of the gear shaft to improve the fixing effect.

[0030] After the three-jaw chuck 12 completes the clamping process of one end of the gear shaft, the movable plate 13 and the jacking tube 18 can move toward the other end of the gear shaft. The jacking tube 18 and the three-jaw chuck 12 are coaxial, and the jacking tube 18 can clamp and fix the other end of the gear shaft, so that the gear shaft can rotate stably, completing the grinding and repair process.

[0031] refer to Figure 4 A rotating table 19 is arranged on one side of the three-jaw chuck 12 on the end surface of the fixed plate 11 , and a second driving motor 22 is arranged in the rotating table 19 . The output end of the second driving motor 22 is connected to the end surface of the three-jaw chuck 12 .

[0032] After the three-jaw chuck 12 completes clamping of one end of the gear shaft, when the gear shaft needs to be polished and repaired, the output end of the second drive motor 22 can drive the three-jaw chuck 12 to rotate, thereby driving the gear shaft to rotate, so as to adjust the repair point on the surface of the gear shaft.

[0033] refer to Figure 7-9 A stepped groove 29 is provided on the end surface of each claw 20 , and a plurality of mounting holes 28 cooperating with the connecting block 23 are provided on the stepped groove 29 .

[0034] The stepped groove 29 provided on the claw 20 allows one end of the connecting block 23 to abut against the stepped surface of the stepped groove 29, thereby improving the radial fixing effect of the connecting block 23. The connecting block 23 is provided with a hole that cooperates with the mounting hole 28. The staff can fix the connecting block 23 on the claw 20 through the mounting hole 28 and bolts.

[0035] refer to Figure 1 A screw driver 15 is arranged on the end surface of the operating table 10, and a first driving motor 17 for driving is arranged at one end of the screw driver 15. A slide 16 is slidably arranged on the screw driver 15, and a movable plate 13 is connected to the end surface of the slide 16.

[0036] The output end of the first driving motor 17 is connected to the screw driver 15, and can drive the screw driver 15. When driven, the screw driver 15 will drive the slide 16 and the movable plate 13 on the slide 16 to move, so that the other end of the gear shaft can be abutted and clamped.

[0037] refer to Figure 2 A pushing cylinder 14 is arranged on the end surface of the moving plate 13 , and a pushing pipe 18 is rotatably connected to the output end of the pushing cylinder 14 .

[0038] The output end of the push cylinder 14 can push the jacking tube 18 to move, thereby providing supporting pressure to the other end of the gear shaft.

[0039] refer to Fig.10 A plurality of hard inner rods 30 are evenly arranged on the end surface of the jacking tube 18 along the circumferential direction, and a conical jacking block 21 is arranged on the outside of each hard inner rod 30 .

[0040] The hard inner rod 30 is made of hard metal material and is evenly distributed on the end surface of the top moving tube 18. It can provide multiple uniform support points while reducing the contact area with the gear shaft end surface to ensure the clamping stability. The conical top block 21 is made of non-slip elastic rubber to avoid damage and ensure the contact effect. The above arrangement can extend the support position when the end of the gear shaft also needs to be repaired, ensuring that the end of the gear shaft is stably repaired and improving the practicality of the device. Embodiment 2:

[0041] On the basis of or different from the first embodiment, reference Figure 6-9 Each claw 20 is provided with an anti-slip pad 25 on both side end surfaces.

[0042] Each anti-skid pad 25 is made of elastic shock-absorbing material, and a plurality of convex strips are arranged on the outer end surface. When the connecting block 23 is sleeved on the outside of the claw 20, the outer end surface of the anti-skid pad 25 will contact the inner wall surface of the connecting block 23, so that when the connecting block 23 and the anti-skid pad 25 are used to clamp the gear shaft for movement for repair, the vibration generated can be partially absorbed by the anti-skid pad 25, thereby ensuring the stability of clamping.
