Device for broaching spline and using method thereof

Abstract

The invention belongs to the technical field of broaching machines and discloses a device for broaching a spline and a using method thereof. The device for broaching the spline comprises a machine body and a base. The machine body is provided with a main slide carriage, a workbench and a tool feeding device. The main slide carriage and the workbench both can move up and down along the machine body. The workbench can clamp a workpiece. The tool feeding device is provided with at least two broaching tools and can drive any broaching tool to be connected to the main slide carriage in a sliding manner. The base is located on the bottom of the machine body and provided with a lower tool clamping base for clamping the broaching tools. According to the device for broaching the spline, the tool feeding device is used for driving any broaching tool to be connected to the main slide carriage in a sliding manner, the main slide carriage descends to the lower tool clamping base along the machine body, and so that the broaching work of the broaching tool on the workpiece is completed; and after broaching, the tool feeding device changes the tool to repeat the operation, and therefore the devicefor broaching the spline can achieve the one-time clamping beneficial effect without repeatedly mounting or demounting the workpiece.

Description

technical field [0001] The invention relates to the technical field of broaching machines, in particular to a device for broaching splines and a method for using the device. Background technique [0002] The bulldozer terminal wheel reducer and gearbox are the core components of the whole machine, and the gear is the key component of the core component. The power of the gear and the spline shaft is basically transmitted by splines or keyways. Splines and keyways in gears are usually processed by broaching, that is, the broaching machine drives the broach to move linearly along the inner hole of the workpiece. However, as the diameter, length, and depth of the inner spline hole increase, the broaching force tonnage of the broaching machine and the length of the broach will increase accordingly, which brings great difficulties to the production of the broaching machine and the broaching tool.

Problems solved by technology

[0003] In the existing technology, two-knife processing is generally used in batches, that is, the rough broaching of the spline is completed at one time, the finishing broach is replaced, and then the fine broaching of the spline is completed again. This method is labor-intensive, low in efficiency, and costly. high

In addition, there is a double-bed broaching machine that can realize one-time positioning of the workpiece, that is, after the rough drawing of the spline, the worktable is rotated or moved to the finishing station for finishing the spline, but the volume of the machine tool for this process is large (equivalent to twice that of an ordinary broaching machine), the weight is too large, which causes great difficulties for the transportation and installation of the machine tool; at the same time, the cost of the machine tool is high (twice the cost of a single machine tool), and it occupies a large area
