Description

Technical Field

[0001] The utility model relates to the technical field of numerically controlled machine tool equipment, in particular to an external supporting device for a numerically controlled lathe. Background Art

[0002] CNC lathe is one of the most widely used CNC machine tools. It is mainly used for cutting and processing of inner and outer cylindrical surfaces of shaft parts or disc parts, inner and outer conical surfaces of arbitrary taper angles, complex rotary inner and outer curved surfaces, and cylindrical and conical threads, and can perform grooving, drilling, reaming, reaming and boring, etc. In daily production and processing, bars are usually installed on CNC lathes for processing, but if the bar is too long, it will be difficult for the bar axis to coincide with the lathe chuck axis, and the bar will shake during processing, which will reduce the processing accuracy, increase the product scrap rate, increase production costs, and waste production resources.

[0003] In a Chinese utility model patent with authorization announcement number CN211192913U, an external support device for a CNC lathe is disclosed, including a CNC lathe and a support device, characterized in that the support device includes a base, a telescopic rod and a mounting frame, the base includes a bottom plate and a column, the column is configured as a hollow column, square grooves are provided at both left and right ends of the upper surface of the column, a slide rail channel is provided at the lower end of the square groove, the telescopic rod passes through the square groove through the slide rail channel, and the mounting frame is vertically arranged on the telescopic rod, which solves the problem that the traditional bar material is too long, so that the axis of the bar material is difficult to coincide with the axis of the lathe chuck.

[0004] However, in the above patent, the method for fixing the rods is to place the rods between the placement plate and the cover plate in the placement frame, and then fix the rods by fixing bolts. The operation is cumbersome, time-consuming and labor-intensive, and only single-specification mixed materials can be fixed. When different rods need to be fixed, the placement plate and the cover plate need to be replaced, which affects the normal processing of the CNC lathe, reduces processing efficiency, and increases production costs.
