Problems solved by technology

[0003] Using the above scheme, use the three-jaw chuck in the machining center to fix the spline shaft. On the one hand, because the spline shaft is short, you need to manually place the spline shaft in the slot of the three-jaw chuck, and The hand-held spline shaft is calibrated multiple times in the card slot to ensure the concentricity of the spline shaft, that is, it is more troublesome to fix, and there is room for improvement

Embodiment 1

[0045] like figure 1 and figure 2As shown, a tooling for a spline shaft includes a mounting plate 1 that is similar to a rectangular parallelepiped. Both ends of the mounting plate 1 in the length direction are provided with mounting grooves 11 for mounting on a processing machine tool. The middle part of the mounting plate 1 is fixed with a rectangular parallelepiped. The clamping plate 2 is provided with a plurality of spline gaps 21 on the long side of the clamping plate 2 for snap-fitting with the protrusions on the spline shaft. In this embodiment, there are four spline gaps 21 . A rectangular sliding groove 12 is provided on the mounting plate 1, and a rectangular parallelepiped abutting plate 3 is slidably provided in the sliding groove 12. The long side of the abutting plate 3 close to the clamping plate 2 is provided with an abutting flower. The abutting notch 31 on the radially outermost side wall of the key shaft, and the number and position of the abutting notch...

Embodiment 2

[0052] like Figure 4 and Figure 5 As shown, a tooling for a spline shaft differs from Embodiment 1 in that:

[0053] The drive group assembly also includes extension springs 42, two extension springs 42 are provided, the mounting plate 1 is located on the side of the abutment plate 3 away from the clamping plate 2, and an insertion groove 13 is provided, and there are two insertion grooves 13, two insertion grooves 13 The length direction of the grooves 13 is parallel to the sliding direction of the abutment plate 3, and the two embedding grooves 13 are arranged symmetrically along the length direction of the mounting plate 1. Two extension blocks 32 are provided. The two extension blocks 32 are respectively embedded in the two insertion grooves 13 , and the corresponding two tension springs 42 are respectively embedded in the two insertion grooves 13 .

[0054] Since the structures and installation methods of the two tension springs 42 are the same, any one of the two ten...

Embodiment 3

[0058] like Image 6 As shown, a tooling for a spline shaft differs from Embodiment 1 in that:

[0059] The drive assembly 4 includes a linear cylinder 43, which is fixed on the mounting plate 1, and the linear cylinder 43 is located in the middle of the abutment plate 3, and the end of the piston rod of the linear cylinder 43 is fixed with a concave connecting plate 6 by bolts, The abutment plate 3 is fixed on the opening end of the connecting plate 6 , and the movement direction of the piston rod of the linear cylinder 43 is parallel to the sliding direction of the abutment plate 3 .

[0060] The method of using the tooling will be further elaborated below in conjunction with specific actions: In actual use, the linear cylinder 43 is used to directly drive the abutment plate 3 to slide on the mounting plate 1 along the direction close to the clamping plate 2 and away from the clamping plate 2, high degree of automation.

Abstract

The invention discloses a tooling for a spline shaft and a using method thereof, and relates to the technical field of spline processing. The block forms a snap fit spline notch, and the mounting plate is slid along the direction away from the spline notch to be provided with an abutment plate, and the corresponding spline notch on the abutment plate is provided with a spline for abutting against the spline. The axis is radial to the abutting notch on the outermost side wall, and a driving assembly for driving the abutting plate to slide is arranged on the mounting plate. The present invention can realize the positioning and fixing of multiple spline shafts at one time by using the tooling, and then fix the mounting plate on the processing machine tool to complete the fixing operation of multiple spline shafts, which simplifies the fixing steps of the spline shafts. Thereby, the processing efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of spline processing, in particular to a tooling for a spline shaft and a using method thereof. Background technique [0002] The spline shaft is a kind of mechanical transmission part. There are longitudinal key grooves on the outer surface of the shaft, and the rotating parts sleeved on the shaft also have corresponding key grooves, which can keep synchronous rotation with the shaft. In the existing technology, such as Figure 7 As shown, there is a spline shaft, including a spline shaft body 10, the shaft body length of the spline shaft body 10 is relatively short, and a through hole 20 is opened on the spline shaft body 10, and the diameter of the spline shaft body 10 is Cutting grooves 30 are formed symmetrically on both sides of the direction, and a plurality of protrusions 40 are arranged in a circular array on the spline shaft body 10 along its circumferential direction. For the formation of the cut...
