Description

Technical Field

[0001] The utility model relates to the technical field of positioning tooling, in particular to a clutch input shaft grinding positioning tooling. Background Art

[0002] The main purpose of clutch input shaft grinding is to improve surface accuracy, ensure dimensional accuracy, improve surface roughness, remove processing marks, and meet assembly requirements. Grinding of clutch input shaft is of great significance to improving the performance, stability and reliability of the clutch. Through reasonable grinding process and parameter selection, high-quality processing effects can be achieved to meet the use requirements of the clutch.

[0003] In the process of implementing the solution, the inventors found that the following problems existed in the prior art and have not been well solved: since the two ends of the key shaft are clamped by a clamp and driven by a rotating mechanism to rotate during grinding, and are also moved left and right during grinding by a left and right moving mechanism, but because it is a clamping limit and the grinding process involves downward pressure, there is a certain probability that the input shaft will have a slight positional deviation when being ground, resulting in unfinished grinding defective products after the input shaft is not ground, which requires rework during subsequent quality inspection, causing unnecessary trouble. Utility Model Content

[0004] The main purpose of the utility model is to provide a clutch input shaft grinding and positioning tool, which can effectively solve the problems in the background technology.

[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0006] The clutch input shaft grinding and positioning tooling comprises a workbench, with four mounting seats arranged above the workbench, through holes being bored at the front and rear ends of the mounting seats, a number of screw holes being equidistantly bored at the positions of the through holes on the workbench, screw rods being inserted through the through holes, nuts being threadedly connected to the outer walls of the screw rods, support tubes being fixed on the tops of the mounting seats, push rod motors being fixed on the inner bottom ends of the support tubes, support rods being inserted at the inner top ends of the support tubes, support frames being fixed on the tops of the support rods, two of the support frames being provided with transverse rollers, and the other two support frames being provided with vertical rollers.

[0007] Preferably, the bottom of the nut is in contact with the top of the mounting seat respectively, and the bottom of one end of the screw rod passes through the through hole and is respectively inserted into the inside of the screw hole and threadedly connected therewith.

[0008] Preferably, the output ends of the push rod motors are respectively fixedly connected to the bottom ends of the support rods inserted into the support tubes.

[0009] Preferably, the outer wall of the support rod is provided with a plurality of splines, the inner wall of the support tube is provided with a plurality of key slots, and the splines are respectively inserted into the key slots and slidably connected thereto.

[0010] Preferably, the number of vertical rollers in the two support frames is no less than two.

[0011] Preferably, the transverse roller and the vertical roller are rotatably connected to supporting frames with matching positions respectively.

[0012] Compared with the prior art, the utility model has the following beneficial effects:

[0013] 1. When the clamping mechanism clamps the input shaft and performs rotational grinding through the rotating mechanism, the transverse roller at the end of the input shaft away from the grinding workpiece supports the input shaft during rotation. When the input shaft is driven by the left and right moving mechanism to reciprocate left and right, the vertical roller supports the input shaft when it moves left and right, so that the downward force during grinding will not cause the input shaft to deviate, thereby enabling the input shaft to have a supporting and positioning effect during the grinding process, while also ensuring the success rate of the grinding process.

[0014] 2. When the rotation and left and right movement are switched, the push rod motor in the support tube works, and the lifting and lowering of the push rod motor will drive the support rod and the support frame to lift and lower together, so that the transverse roller and the vertical roller follow the lifting and lowering. When rotation is required, the transverse roller rises and contacts the outer wall at the bottom of the input shaft, while the vertical roller descends and does not contact the outer wall at the bottom of the shaft, thereby providing support during rotation. When left and right reciprocating movement is required, the vertical roller rises and contacts the shaft body, while the transverse roller descends and does not contact it, thereby providing support during left and right movement, thereby avoiding the influence of the transverse roller or vertical roller on its movement during different movements.

[0015] 3. After the through holes on the mounting seat are matched with the screw holes at different positions, the screw rod is passed through the bottom end of the through hole and threadedly connected to the screw hole, and the nut is connected to the nut through the top end of the screw rod through the through hole, so that the mounting seat can be installed on the workbench, and the mounting seat can be adjusted according to the length of the input shaft, so that the horizontal roller and the vertical roller can support and position the input shaft with an appropriate length during grinding.

[0021] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0022] like Figure 1-4 As shown, the clutch input shaft grinding and positioning tooling includes a workbench 1, four mounting seats 2 are arranged above the workbench 1, through holes 4 are drilled at the front and rear ends of the mounting seats 2, a number of screw holes 3 are drilled at equal intervals at the positions of the through holes 4 on the workbench 1, screw rods 5 are inserted through the through holes 4, nuts 6 are threadedly connected to the outer walls of the screw rods 5, support tubes 7 are fixed on the tops of the mounting seats 2, push rod motors 8 are fixed on the inner bottom ends of the support tubes 7, support rods 9 are inserted on the inner top ends of the support tubes 7, support frames 10 are fixed on the tops of the support rods 9, two of the support frames 10 are provided with transverse rollers 11, and the other two support frames 10 are provided with vertical rollers 12.

[0023] Specifically, the bottom of the nut 6 is in contact with the top of the mounting seat 2, and the bottom of the screw rod 5 passes through one end of the through hole 4 and is inserted into the inside of the screw hole 3 and threadedly connected thereto, so that the workbench 1 and the mounting seat 2 are convenient for disassembly and assembly.

[0024] Specifically, the output ends of the push rod motor 8 are fixedly connected to the bottom ends of the support rod 9 inserted into the support tube 7. The outer wall of the support rod 9 is provided with a plurality of splines 91, and the inner wall of the support tube 7 is provided with a plurality of key grooves 71. The splines 91 are respectively inserted into the key grooves 71 and slidably connected thereto, so that the lifting and lowering of the support frame 10 is more stable.

[0025] Specifically, the number of the vertical rollers 12 in the two support frames 10 is no less than two, so as to provide a better supporting and positioning effect during movement.

[0026] Specifically, the transverse roller 11 and the vertical roller 12 are rotatably connected to the supporting frame 10 at matching positions.

[0027] Working principle: When the clamping mechanism clamps the input shaft and performs rotational grinding through the rotating mechanism, the transverse roller 11 at the end of the input shaft away from the grinding piece supports the input shaft during rotation. When the input shaft is driven by the left and right moving mechanism to move back and forth left and right, the vertical roller 12 supports the input shaft when it moves left and right, so that the downward pressure during grinding will not cause the input shaft to deviate, thereby enabling the input shaft to have a supporting and positioning effect during the grinding process, while also ensuring the success rate of the grinding process. When the rotation and left and right movement are switched, the push rod motor 8 in the support tube 7 works, and the lifting and lowering of the push rod motor 8 will drive the support rod 9 and the support frame 10 to lift together, so that the transverse roller 11 and the vertical roller 12 follow the lifting and lowering. When rotation is required, the transverse roller 11 rises and moves with the input The bottom outer wall of the shaft is in contact, while the vertical roller 12 is lowered and does not contact the bottom outer wall of the shaft, thereby providing support during rotation. When it is necessary to move back and forth left and right, the vertical roller 12 rises and contacts the shaft body, and the transverse roller 11 is lowered and does not contact it, thereby providing support during left and right movement, thereby avoiding the transverse roller 11 or the vertical roller 12 from affecting its movement during different movements. After the through-holes 4 on the mounting seat 2 are matched with the screw holes 3 at different positions, the screw rod 5 is passed through the bottom end of the through-hole 4 and is threadedly connected to the screw hole 3, and the nut 6 is connected to the nut 6 through the top end of the screw rod 5 through the through-hole 4, thereby enabling the mounting seat 2 to be installed on the workbench 1, thereby enabling the mounting seat 2 to adjust its position according to the length of the input shaft, so that the transverse roller 11 and the vertical roller 12 can support and position the input shaft with an adapted length during grinding.
