Description

Large spline shaft processing device

technical field

The utility model relates to a large spline shaft processing device, which belongs to the technical field of machine tools.

Background technique

At present, in the heavy machinery and equipment manufacturing industry, such as the steel rolling equipment manufacturing industry, some commonly used large-sized shafts need to be processed with external splines, but the existing large-scale spline milling machines have limited processing capacity and cannot process such super-sized shafts , and customizing such a large spline processing milling machine is expensive, and the utilization rate is low, so it is very impractical.

Utility model content

Based on the above deficiencies in the prior art, the technical problem to be solved by the utility model is to provide a large spline shaft processing device, which has a wide application range and is economical and practical.

The large-scale spline shaft processing device described in the utility model includes a workbench located on a horizontal ground, positioning fixtures are provided at both ends of the workbench, a ground groove is provided on one side of the workbench, and a tool moving device is arranged in the ground groove. The tool moving device includes a horizontal moving box, which is installed on a linear rail, and a tool holder is installed on the horizontal moving box, and the tool holder is connected to the horizontal moving box through a vertical guide rail. The machine is connected to the tool holder through the screw drive mechanism.

Fix the shaft to be processed on the positioning fixture, the tool moving device can drive the tool holder to move horizontally and vertically, and the tool can also move forward and backward relative to the tool holder. The adjustment range is large, and large spline shafts can be processed. .

A number of V-shaped support blocks are installed between the two positioning fixtures of the workbench to ensure the stability of the workpiece and improve the machining accuracy.

The workbench is provided with several parallel T-shaped slots, and according to the size of different workpieces to be processed, the positioning fixture is fixed on the corresponding T-shaped slots with T-shaped bolts.

Compared with the prior art, the utility model has the following beneficial effects:

The design of the large spline shaft processing device is reasonable, not only suitable for spline processing of ordinary size range workpieces, but also suitable for spline processing of large size shafts, and can also replace the tool for boring and drilling, high utilization rate, economical and practical .

detailed description

Embodiments of the utility model are further described below in conjunction with the accompanying drawings:

As shown in Figures 1 and 2, the large-scale spline shaft processing device includes a workbench 2 located on a horizontal ground 1. Positioning fixtures 6 are provided at both ends of the workbench 2, and a ground groove 8 is provided on one side of the workbench 2. The slot 8 is provided with a tool moving device, which includes a horizontal moving box 5, which is mounted on a linear rail. On the box 5, the top of the horizontally moving box 5 is provided with a worm gear reducer, and the worm gear reducer is connected to the tool holder 3 through a screw drive mechanism.

Several V-shaped support blocks 7 are installed between the two positioning fixtures 6 of the workbench 2 .

The workbench 2 is provided with several parallel T-shaped slots.

When in use, first fix the positioning fixture 6 on the workbench 2 according to the size of the workpiece to be processed, then fix the axis to be processed on the positioning fixture 6, the linear rail 9 drives the horizontal moving box 5 to move horizontally and adjust, and the turbine reducer drives the tool The frame 3 moves vertically for adjustment, and the tool can also be fed back and forth relative to the tool frame 3. The adjustment range is large, and large spline shafts can be processed.

Different cutting tools can also be replaced for boring and drilling processing, which improves the utilization rate and is economical and practical.
