Description

Technical Field

[0001] The utility model relates to a kind of tooling field, specifically a clamping tool for the spline shaft inclined oil hole of a wind power gearbox. Background Technique

[0002] Due to the advantages of pollution-free and low construction cost, wind power generation has developed rapidly in recent years.

[0003] In a wind power gearbox, the internal and external splines need an inclined oil hole to connect lubricating oil for lubrication and cooling. Since this inclined oil hole has an angle with the center hole of the spline shaft, therefore, the processing of this inclined oil hole requires a machining center, with a relatively high cost. Content of the Utility Model

[0004] The utility model provides a clamping tool for the spline shaft inclined oil hole of a wind power gearbox, aiming to solve the shortcomings of the prior art, realizing the processing of the spline shaft inclined oil hole of a wind power gearbox on an ordinary drilling machine, with simple operation, reducing the requirements for equipment, reducing costs, and improving versatility.

[0005] The technical solution adopted by the utility model to solve its technical problems is as follows:

[0006] A clamping tool for the spline shaft inclined oil hole of a wind power gearbox, characterized in that:

[0007] The spline shaft is placed on the upper surface of the inclined panel, and the screw passes through the through hole of the inclined panel and is then screwed into the screw hole on the lower end surface of the spline shaft at the corresponding position;

[0008] The stud passes through the shaft hole of the spline shaft;

[0009] The lower end of the stud passes through the through hole of the inclined panel, and the round nut is screwed on the part of the stud exposed under the lower surface of the inclined panel, and the round nut abuts against the lower surface of the inclined panel;

[0010] The upper end of the stud passes through the through hole of the pressing plate, and the round nut is screwed on the part of the stud exposed above the upper surface of the pressing plate and presses tightly on the upper surface of the pressing plate, and the lower surface of the pressing plate presses tightly on the upper end surface of the spline shaft;

[0011] One end of the inclined panel abuts against the upper surface of the workbench;

[0012] The upper end of the connecting thread of the supporting stud is screwed and connected to the corresponding screw hole of the inclined panel; the lower end of the supporting stud abuts against the upper surface of the workbench.

[0014] The axis of the stud coincides with the axis of the shaft hole of the spline shaft.

[0015] The lower end of the support stud is spherical.

[0016] The included angle A between the center line of the inclined oil hole and the center line of the spline shaft is the same as the included angle B between the inclined panel and the upper surface of the workbench.

[0017] The advantages of the present utility model are as follows:

[0018] The present utility model can realize the processing of the inclined oil hole of the spline shaft of the wind power gearbox on an ordinary drilling machine, with simple operation, reduced requirements for equipment, and reduced costs.

[0024] The spline shaft 4 is placed on the upper surface of the inclined panel 6. Four screws 7 respectively pass through four through holes 60 evenly distributed on the circumference of the inclined panel 6, and are then screwed into four through holes 40 evenly distributed on the lower end surface of the spline shaft 4 at corresponding positions.

[0025] The stud 2 passes through the shaft hole 41 of the spline shaft 4 and coincides with the axis of the shaft hole 41.

[0026] The lower end of the stud 2 passes through the through hole 61 of the inclined panel 6. The round nut 51 is screwed on the part of the stud 2 exposed on the lower surface of the inclined panel 6, and the round nut 51 abuts against the lower surface of the inclined panel 6;

[0027] The upper end of the stud 2 passes through the through hole 11 of the pressure plate 1. The round nut 52 is screwed on the part of the stud 2 exposed on the upper surface of the pressure plate 1 and presses tightly on the upper surface of the pressure plate 1. The lower surface of the pressure plate 1 presses tightly on the upper end surface of the spline shaft 4, so that the spline shaft 4 is fixed on the inclined panel 6.

[0028] One end of the inclined panel 6 abuts against the upper surface 91 of the workbench 9.

[0029] The connecting thread at the upper end 32 of the support stud 3 is screwed and connected to the corresponding screw hole 62 in the inclined panel 6; the lower end 31 of the support stud 3 abuts against the upper surface 91 of the workbench 9.

[0030] The lower end 31 of the support stud 3 is a spherical surface polished at the top of the cylindrical surface.

[0031] At this time, the included angle A between the center line of the inclined oil hole 8 and the center line of the spline shaft 4, and the included angle B between the inclined panel 1 and the upper surface 91 of the workbench 9 are the same, and the center line of the inclined oil hole 8 is perpendicular to the horizontal plane.

[0032] The using process of the tooling of the utility model:

[0033] The using process of the tooling:

[0034] 1: According to the angle of the included angle A between the center line of the inclined oil hole 8 and the center line of the spline shaft 4, select the appropriate length of the support stud 3 to ensure that the angle of the included angle B between the inclined panel 1 and the horizontal plane (i.e., the upper surface 91 of the workbench 9) is consistent with the included angle A. In this way, the center line of the inclined oil hole 8 is perpendicular to the horizontal plane;

[0035] 2: One end 32 of the support stud 3 has a connecting thread, and one end 31 is a spherical surface polished at the top of the cylindrical surface;

[0036] 3: Screw the connecting thread at one end 32 of the support stud 3 and connect it to the corresponding screw hole 62 in the inclined panel 6; one end 32 of the support stud 3 abuts against the upper surface 91 of the workbench 9.

[0037] 4: The lower end of the stud 2 passes through the through hole 61 of the inclined plate 6, and the round nut 51 is screwed on the portion of the stud 2 exposed from the lower surface of the inclined plate 6, and the round nut 51 is tightly against the lower surface of the inclined plate 6;

[0038] 5: Lift the spline shaft 4, place the center of the spline shaft 4 on the inclined plate 6 along the stud 2, the stud 2 passes through the shaft hole 41 of the spline shaft 4 and coincides with the axis of the shaft hole 41, and align the four circumferentially evenly distributed screw holes 40 on the lower end surface of the spline shaft 4 with the four circumferentially evenly distributed through holes 60 of the inclined plate 6, and screws 7 pass through the through holes 60 and are screwed into the screw holes 40, so that the spline shaft 4 is positioned on the inclined plate 6;

[0039] 6: The upper end of the stud 2 passes through the through hole 11 of the pressure plate 1, and the round nut 52 is screwed on the end of the stud 2 passing through the through hole 11 and pressed tightly against the upper end surface of the pressure plate 1. The lower end surface of the pressure plate 1 presses the upper end surface of the spline shaft 4, so that the spline shaft 4 is fixed on the inclined plate 6.

[0040] At this point, the clamping tooling is completed, and the drill bit of the drilling machine can directly and normally process the inclined oil hole 8 vertically.

[0041] By controlling the length of the support stud 3, the angle B between the inclined plate 1 and the horizontal plane (ie, the upper surface 91 of the workbench 9) can be adjusted, so that the inclined oil holes 8 of different angles can be processed on a common drilling machine.
