Description

Technical Field

The utility model relates to a cutter for workpiece surface machining, in particular to a distance-adjustable double-sided synchronous machining cutter based on counter-force locking connection.

Background

The surface of the workpiece is required to be subjected to turning, grinding and other processing treatments, and a general processing method is that a cutter is kept fixed, the workpiece is driven to rotate, and rough processing or finish processing of the surface of the workpiece is finished, for example, a turning tool is a cutter for turning the surface of the workpiece.

As shown in fig. 1, a conventional machining method for machining the surface of a workpiece 3 is to use a single-sided machining tool, that is, a tool bit 2 mounted at one end of a tool bar 1 is used to machine one surface of the workpiece 3, the tool bar 1 is fixed on a machine tool, the workpiece 3 is mounted on a rotating shaft, and the surface of the workpiece 3 contacts with the cutting edge of the tool bit 2 during the high-speed rotation process of the workpiece 3, so as to finish the machining.

In practical application, two side surfaces of some workpieces need to be machined, such as a connecting flange at the end part of a rotating shaft, two side grinding machining is needed, if the cutter is adopted, two times of machining are needed, or two cutters are installed simultaneously for machining, the efficiency of the former is low, the synchronism between the two cutters is not guaranteed, the consistency of machining two sides of the workpiece is poor, and two installation stations are needed.

In order to improve the machining efficiency and simultaneously ensure the consistency of machining of the two sides of a workpiece, a double-sided synchronous machining tool is ideal, the double-sided synchronous machining tool is provided with two tool bars and two tool bits, the two tool bars are parallel to each other, the two tool bits are respectively arranged at one ends of the two tool bars, the other ends of the two tool bars are fixedly connected or integrally formed, the tool can synchronously machine the two sides of the workpiece, the efficiency is improved, the machining consistency of the two sides of the workpiece is good, and only one installation station is needed.

However, the two cutter bars of the traditional double-sided synchronous processing cutter are fixedly connected or integrally formed, the distance cannot be adjusted, and different cutters are required to process workpieces with different thicknesses, so that the adaptability of the cutters is poor, and the enterprise cost is increased; meanwhile, since the distance between the two tool bits cannot be adjusted, the machining amount of the two sides of the workpiece cannot be adjusted, and the tool bit is not applicable to workpieces requiring finish machining.

Therefore, if a double-sided synchronous machining tool with an adjustable distance between two tool bars can be provided, and the adjustment mode is simple, feasible, quick and efficient, the problems can be solved.
