Description

Technical Field

[0001] This utility model relates to the field of spline shaft machining technology, and more specifically, to a spline shaft machining fixture. Background Technology

[0002] Splined shafts are a type of mechanical transmission, similar in function to parallel keys, semicircular keys, and wedge keys, all of which transmit mechanical torque. They have longitudinal keyways on the outer surface of the shaft, and the rotating parts fitted on the shaft also have corresponding keyways, which can keep them rotating synchronously with the shaft. While rotating, some can also slide longitudinally on the shaft, such as gearbox shift gears.

[0003] Existing spline shaft machining fixtures, when machining long spline shafts, require machining only one end of the spline shaft, so only the other end of the spline shaft can be fixed, causing an imbalance and easily leading to errors during machining.

[0004] No effective solutions have yet been proposed to address the problems in the relevant technologies. Utility Model Content

[0005] In view of the problems in the related technologies, this utility model proposes a spline shaft machining fixture to overcome the above-mentioned technical problems existing in the existing related technologies.

[0006] Therefore, the specific technical solution adopted by this utility model is as follows:

[0007] A spline shaft machining fixture includes two sets of symmetrically arranged supports, with a transversely connected beam between the two sets of supports. The top of each support is provided with a clamping mechanism for clamping the spline shaft. The clamping mechanism includes a clamping plate one and a clamping plate two symmetrically arranged. Each clamping plate one and the clamping plate two has a clamping groove on one side that is close to each other. The clamping plate one and the clamping plate two are provided with a fixed shaft at the bottom of the clamping groove. A push-pull rod is movably connected to the fixed shaft.

[0008] Preferably, the clamping mechanism further includes a U-shaped frame, the top of which is provided with a rotating shaft that is movably connected to the first clamping plate and the second clamping plate, and the first clamping plate and the second clamping plate are provided with a movable shaft that passes through the U-shaped frame.

[0009] Preferably, the U-shaped frame has a travel hole for the movable shaft to move, and the bottom end of the push-pull rod is movably connected to a connecting shaft that passes through the U-shaped frame.

[0010] Preferably, the U-shaped frame has a second stroke hole for the connecting shaft to move, and a hydraulic cylinder connected to the end of the connecting shaft is provided on one side of the U-shaped frame.

[0011] Preferably, there are four sets of clamping plates one and four sets of clamping plates two, and the push-pull rods are arranged at an angle.

[0012] Preferably, the bracket is provided with an electrically operated telescopic rod for adjusting the height of the clamping mechanism.

[0013] Preferably, a rubber pad is provided in the clamping groove.

[0014] The beneficial effects of this utility model are as follows: by setting up a clamping mechanism, different spline shafts can be positioned, effectively preventing the spline shafts from moving during processing, thereby improving processing efficiency and avoiding the problem of imbalance when fixing one end, which can easily lead to errors during processing.

These drawings are mainly used to illustrate the embodiments and can be used in conjunction with the relevant descriptions in the specification to explain the operating principles of the embodiments.

The components in the figures are not drawn to scale, and similar component symbols are usually used to represent similar components.

[0023] According to an embodiment of the present invention, a spline shaft machining fixture is provided.

[0024] Example 1:

[0025] like Figure 1-4 As shown, the spline shaft machining fixture according to an embodiment of the present utility model includes two sets of symmetrically arranged brackets 1, with a transversely connected crossbeam 2 between the two sets of brackets 1. The top of each bracket 1 is provided with a clamping mechanism 3 for clamping the spline shaft. The clamping mechanism 3 includes a clamping plate 4 and a clamping plate 5 symmetrically arranged. A clamping groove 6 is provided on the side of the clamping plate 4 and the clamping plate 5 that are close to each other. A fixed shaft 7 is provided at the bottom of the clamping groove 6 of the clamping plate 4 and the clamping plate 5. A push-pull rod 8 is movably connected to the fixed shaft 7.

[0026] Example 2:

[0027] like Figure 1-4 As shown, the clamping mechanism 3 also includes a U-shaped frame 9. The top of the U-shaped frame 9 is provided with a rotating shaft 10 that is movably connected to the clamping plate 4 and the clamping plate 5. The clamping plate 4 and the clamping plate 5 are provided with a movable shaft 11 that passes through the U-shaped frame 9. The U-shaped frame 9 is provided with a stroke hole 12 for the movable shaft 11 to move. The bottom end of the push-pull rod 8 is movably connected to a connecting shaft 13 that passes through the U-shaped frame 9. The U-shaped frame 9 is provided with a stroke hole 14 for the connecting shaft 13 to move. A hydraulic cylinder 15 is provided on one side of the U-shaped frame 9 that is connected to the end of the connecting shaft 13.

[0028] Example 3:

[0029] like Figure 1-4 As shown, there are four sets of clamping plates 4 and four sets of clamping plates 5, and the push-pull rod 8 is inclined. The bracket 1 is provided with an electric telescopic rod 16 for adjusting the height of the clamping mechanism 3, and a rubber pad is provided in the clamping groove 6.

[0030] To facilitate understanding of the above-mentioned technical solutions of this utility model, the working principle or operation method of this utility model in actual process will be described in detail below.

[0031] In practical applications, the spline shaft to be processed is first placed between clamping plate 4 and clamping plate 5 of clamping mechanism 3. The hydraulic cylinder 15 is started to drive the connecting shaft 13 to move down. The connecting shaft 13 drives clamping plate 4 and clamping plate 5 to rotate in the same direction around the pivot 10 through the push-pull rod 8, so that clamping plate 4 and clamping plate 5 clamp and fix the spline shaft. At this time, the hydraulic cylinder 15 is stopped to achieve positioning of different spline shafts. This avoids the problem of imbalance when fixing one end, which can easily lead to errors during processing.

[0032] In summary, by utilizing the above-mentioned technical solution of this utility model, the clamping mechanism 3 enables the positioning of different spline shafts, effectively preventing the spline shafts from moving during processing, thereby improving processing efficiency and avoiding the problem of imbalance when one end is fixed, which can easily lead to errors during processing.
