Description

Technical Field

[0001] This utility model relates to the field of secondary processing technology for spline shafts, specifically to a device for facilitating secondary processing of holes and grooves in spline shafts. Background Technology

[0002] Splined shafts are a type of mechanical transmission, functioning similarly to flat keys, semi-circular keys, and bevel keys—transmitting mechanical torque. They have longitudinal keyways on their outer surface, and rotating components fitted onto the shaft also have corresponding keyways to maintain synchronous rotation with the shaft. While rotating, some splined shafts can also slide longitudinally along the shaft, such as gearbox shift gears.

[0003] When machining holes and grooves on a splined shaft, it is necessary to clamp the splined shaft firmly to ensure machining accuracy and to ensure that the opening and grooving are stable enough to guarantee the machining effect. The clamping fixtures currently used are not flexible in application and can easily block the opening position on the end face of the splined shaft or the groove position on the outer surface of the splined shaft, thus hindering the machining. Utility Model Content

[0004] This utility model aims to solve one of the technical problems existing in the prior art or related technologies.

[0005] Therefore, the technical solution adopted by this utility model is as follows:

[0006] A device for facilitating secondary machining of holes and grooves on a splined shaft includes a support mechanism and a fastening mechanism. The support mechanism includes a splined shaft and two support seats movably sleeved at both ends of the splined shaft. The fastening mechanism includes multiple threaded rods slidably passing through the support seats, two nuts screwed to the threaded rods, a guide shell connected to one end of the threaded rods, a slider slidably installed inside the guide shell, multiple bolts screwed to one side of the guide shell, and a locking block connected to the slider. The locking block is movably engaged with the splined shaft.

[0007] By adopting the above technical solution, the threaded rod is moved along the support base, and the position of the guide shell connected to the threaded rod on the spline shaft is adjusted so that it avoids the machining hole and groove. Then, the nut is tightened, and the slider is moved along the guide shell so that the locking block is aligned with the groove opened on the spline shaft. Then, the bolt is tightened to fix the slider as a whole. Then, the support base is sleeved on the outside of the spline shaft, and multiple locking blocks cooperate to firmly lock the spline shaft, preventing the spline shaft from shifting during secondary processing and making the processing operation smoother.

[0008] In a preferred embodiment, the present invention can be further configured such that: the support base has multiple insertion holes suitable for threaded rod insertion, the multiple insertion holes are equally spaced and arranged in three rows, and the three rows of insertion holes are arranged in a ring.

[0010] In a preferred embodiment, the present invention can be further configured such that the two nuts on the threaded rod are respectively attached to both sides of the support base.

[0011] In a preferred embodiment, the present invention can be further configured such that the slider is convex and the length of the slider is one-quarter of the length of the guide shell.

[0012] In a preferred embodiment, the present invention can be further configured such that: a plurality of bolts on the guide shell are equally spaced and arranged in a fan shape, and the inner ends of the bolts extend into the interior of the guide shell.

[0030] Furthermore, the slider 240 is configured as a convex shape, and the length of the slider 240 is set to one-quarter of the length of the guide shell 230. The shape design of the slider 240 ensures that the slider 240 will not detach from the guide shell 230.

The layout design of the sockets 300 can precisely control the outward movement distance of the threaded rod 210, ensuring that the locking block 260 can be locked with any size splined shaft 110.

[0035] Example 3:

[0036] Combination Figure 3-4 As shown, in the above embodiment, the two nuts 220 on the threaded rod 210 are respectively attached to both sides of the support base 120. The arrangement of the nuts 220 provides conditions for fixing the threaded rod 210 and the support base 120.
