Workpiece multi-stage positioning device applied to numerical control milling machine

Abstract

The invention discloses a workpiece multi-stage positioning device applied to a numerical control milling machine, and belongs to the technical field of workpiece positioning. The workpiece multistage positioning device comprises a base, a through hole is formed in the upper surface of the base, a two-way threaded rod is arranged in the through hole, the two ends of the two-way threaded rod are rotatably connected to the two sides of the inner wall of the through hole through bearings, the outer surface of the two-way threaded rod is in threaded connection with two threaded caps, and the upper surfaces of the threaded caps are fixedly connected with the lower surface of a pushing and pressing assembly. According to the workpiece multi-stage positioning device applied to the numerical control milling machine, the threaded rod, the threaded caps, an air guide plate, a pressing plate, push plates, a first piston plate, a second piston plate and a pressure valve are arranged, the two push plates can limit the two sides of a workpiece, and compared with traditional repeated operation, by means of the scheme, the burden of workers is relieved, the purpose of multi-stage positioning of the workpiece is achieved, the workpiece is not prone to deviation in the machining process, and the machining precision of the workpiece is improved.

Description

technical field [0001] The invention belongs to the technical field of workpiece positioning, in particular to a multi-level workpiece positioning device applied to a numerically controlled milling machine. Background technique [0002] CNC milling machine, also known as CNC milling machine, English means milling machine controlled by digital signal of electronic meter. CNC milling machine is an automatic processing equipment developed on the basis of general milling machine. The processing technology of the two is basically the same, and the structure is somewhat similar. CNC milling machines can be divided into two categories without tool magazines and with tool magazines. Among them, CNC milling machines with tool magazines are also called machining centers. , flexible processing units, etc. are all produced on the basis of CNC milling machines and CNC boring machines, both of which are inseparable from the milling method. Since the NC milling process is the most complex...

Problems solved by technology

[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides a workpiece multi-level positioning device applied to CNC milling machines, which solves the problem of press-fitting and fixing various positions of the workpiece through multiple sets of pressing blocks and bolts, and repetitive operations. It brings a large burden to the staff, and the processing efficiency is low; at the same time, when the workpiece is fixed by the pressing block, the workpiece can only be stressed in one direction, and the multi-level positioning of the workpiece cannot be achieved, and the workpiece is easy to shift its position during processing. question
