[0010]The beneficial effects of this utility model are as follows: When in use, the mounting base is installed on the tailstock of the machine tool. When the shaft to be processed is fixed by the two ends of the machine tool, the shaft to be processed does not contact the V-groove. After processing, the tailstock tip moves backward in the tailstock of the machine tool to release the shaft to be processed. The shaft to be processed then falls into the V-groove and is supported, thus preventing damage caused by falling due to lack of support after processing. At the same time, after processing, the tailstock tip can directly release the shaft, allowing the worker to directly remove it when unloading, which improves unloading efficiency.

Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of shaft component processing equipment, specifically relating to an auxiliary support frame for shaft component processing. Background Technology
[0002] When machining shaft components, they are usually clamped together by a chuck and a center or two centers. However, for shaft components, especially long shaft components, after machining, the center at the rear end will move backward, causing the rear end of the shaft to fall directly downward, thus damaging the machined shaft. Currently, to prevent this from happening, the shaft is usually manually held after machining, and then the tailstock center is released. This operation method increases the unloading time, thereby reducing efficiency. Utility Model Content
[0003] This utility model aims to provide an auxiliary support frame for machining shaft-type parts, which can be fixed on the tailstock of a machine tool to prevent the shaft from falling and being damaged when the shaft-type parts are finished and the tailstock tip is released.
[0004] Therefore, the technical solution adopted by this utility model is as follows: an auxiliary support frame for machining shaft-type parts, including a mounting base, a connecting member parallel to the axis of the shaft to be machined is provided on the mounting base, and a support member is provided at the other end of the connecting member through an adjustable mounting structure. A V-groove is provided at the upper end of the support member. The adjustable mounting structure includes an adjusting hole provided on the connecting member, a threaded rod provided below the support member, and locking nuts located on the upper and lower sides of the adjusting hole are screwed onto the threaded rod, with the outer diameter of the locking nuts being larger than that of the adjusting hole.
[0005] As a preferred embodiment of the above scheme, the threaded rod is configured as a bolt welded to the bottom of the support member, and the bolt head is welded to the support member.
[0006] Further preferably, the mounting base is provided with two mounting holes for fixing to the tailstock of the machine tool, and one mounting hole is a strip-shaped hole extending front and back, and the other mounting hole is a strip-shaped hole extending left and right.
[0007] Further preferably, the mounting base is provided with a top relief groove.
[0008] Further preferably, the connector is provided with a groove that matches the mounting base, and the connector and the mounting base are connected by welding.
[0009] More preferably, the distance between the bottom of the V-groove and the bottom of the shaft to be processed is between 5-10mm, and the V-groove is located below the center of gravity of the shaft to be processed.
[0010] The beneficial effects of this utility model are as follows: When in use, the mounting base is installed on the tailstock of the machine tool. When the shaft to be processed is fixed by the two ends of the machine tool, the shaft to be processed does not contact the V-groove. After processing, the tailstock tip moves backward in the tailstock of the machine tool to release the shaft to be processed. The shaft to be processed then falls into the V-groove and is supported, thus preventing damage caused by falling due to lack of support after processing. At the same time, after processing, the tailstock tip can directly release the shaft, allowing the worker to directly remove it when unloading, which improves unloading efficiency.

[0014] The present invention will be further described below with reference to embodiments and accompanying drawings:
[0015] like Figure 1-2 As shown, an auxiliary support frame for machining shaft-type components mainly consists of a mounting base 10, a connecting member 20, a support member 30, and an adjustable mounting structure. The mounting base is used to mount the entire support frame onto a machine tool tailstock 60. A connecting member 20 parallel to the axis of the shaft to be machined is provided on the mounting base 10. At the other end of the connecting member 20, the support member 30 is mounted via the adjustable mounting structure. A V-groove 31 for auxiliary support of the shaft to be machined is provided at the upper end of the support member 30. The adjustable mounting structure allows for adjustable mounting of the support member on the connecting member, thus making the entire support frame suitable for supporting shafts of various specifications.
[0016] The specific structure of the adjustment installation structure includes an adjustment hole 21 on the connector 20, a threaded rod 40 below the support 30 with a larger diameter than the adjustment hole, and locking nuts 50 located on the upper and lower sides of the adjustment hole on the threaded rod 40 with an outer diameter larger than the adjustment hole 21. When the two locking nuts are clamped on the connector, the support can be fixed after adjustment, and the distance between the V-groove and the axis to be machined can be adjusted by adjusting the position of the two locking nuts on the threaded rod.
[0017] Preferably, the threaded rod 40 is configured as a bolt welded to the underside of the support member 30, and the bolt head is welded to the support member 30. A groove matching the bottom of the mounting base 10 is provided on the connector 20, and the connector 20 and the mounting base 10 are connected by welding, wherein the groove is used for positioning the connector during welding to the mounting base.
[0018] To facilitate the installation of the mounting base and the machine tool, the mounting base 10 is provided with two mounting holes 11 for fixing to the tailstock of the machine tool. One mounting hole 11 is a strip-shaped hole extending front and rear, and the other mounting hole 11 is a strip-shaped hole extending left and right, which facilitates the adjustment of the installation position and ensures that the connecting part is parallel to the axis of the shaft to be processed. Since the mounting base is installed on the tailstock of the machine tool, it is preferable to provide a center clearance groove 12 on the mounting base 10.
[0019] To ensure effective support during material handling, after installation, the bottom of the V-groove 31 should be 5-10mm away from the bottom of the shaft to be processed. The position of the V-groove 31 should be adjusted so that it is below the center of gravity of the shaft. Because of the small distance between the V-groove and the workpiece, this support frame can also be used to assist in material loading. During loading, one end of the shaft is supported by a center pin, and the other end by the V-groove. Then, during clamping movement, the center pin at the other end will lift and clamp the shaft along the center pin hole, thus achieving shaft clamping. In this process, only the shaft needs to be placed; it is not necessary to hold it until it is clamped, thereby improving loading efficiency.
