Automatic processing equipment for keyway in through hole

Abstract

The invention discloses automatic machining equipment for keyways in through holes. The automatic machining equipment comprises a hydraulic pump, a motor and a control device. The hydraulic pump is connected with two hydraulic cylinders, one hydraulic cylinder is connected to the upper portion of a toolbar, the other hydraulic cylinder is connected with a clamping push rod of a clamping device, the motor is connected with a feeding device, and the control device is connected with the hydraulic pump and the motor. The automatic machining equipment has the advantages that the hydraulic pump and the motor are controlled according to set parameters by the aid of the control device with integrated circuits, two hydraulic systems are controlled by the hydraulic pump, and the toolbar can move up and down under the control of one hydraulic system so that the keyways can be automatically completely machined, and workpieces can be positioned by a clamping system under the control of the other hydraulic system; the feeding device can be driven by the motor to automatically advance and retreat, and accordingly a keyway cutting feed effect and post-cutting yielding and relieving effects can be realized; integral machining procedures are automatically controlled, accordingly, the automatic machining equipment is convenient to operate, is safe and is particularly suitable for conditions where keyways are difficult to machine by common equipment, energy can be saved, and the production efficiency can be greatly improved.

Description

technical field [0001] The invention relates to mechanical processing equipment, in particular to key groove processing, and more specifically to an automatic processing equipment for key grooves in through holes. Background technique [0002] There are slotting method, planing method, broaching method and wire cutting method for processing inner hole keyway. The slotting method requires a special machine tool, and the tool is easy to damage; the planing method is inefficient; the broaching method is expensive to manufacture; the wire cutting method is suitable for small-diameter workpieces, but for large-diameter workpieces and wider, deeper and longer keyways Processing does not have an advantage. In addition, the above methods generally have problems such as many processing steps, long time, and low efficiency. Contents of the invention [0003] In order to overcome the above disadvantages, improve the degree of automation and improve work efficiency, the present inve...
