Specially-shaped part clamping equipment of numerically-controlled lathe

Abstract

The invention provides specially-shaped part clamping equipment of a numerically-controlled lathe, belongs to the technical field of tool fixtures, and aims to solve the problems that existing tool fixtures of numerically-controlled lathes are single in function, specially-shaped parts cannot be clamped directly, the production precision is difficult to guarantee and the production quality is reduced. The equipment comprises an upper clamping plate; each of the upper clamping plate and a lower clamping plate adopts the half-cylindrical-pipe-shaped structure; the front end of the upper clampingplate and the front end of the lower clamping plate are distributed in the half-horn shapes. According to the equipment, an upper cushion block and a lower cushion block are added to the outside of aspecially-shaped casing pipe part, a first arc-shaped surface is formed at the front end of the upper cushion block, a second arc-shaped surface is formed at the front end of the lower cushion block,the arc-shaped surfaces are matched with the horn mouth part of the specially-shaped casing pipe part in diameter, the specially-shaped casing pipe part is clamped between the cushion blocks during clamping, the middle section of the part can be thickened, the horn mouth can be avoided, the specially-shaped casing pipe part can be clamped firmly, the specially-shaped part can be clamped easily and quickly, the influence of the specially-shaped part on production and machining can be eliminated, and the production quality is guaranteed.

Description

technical field [0001] The invention belongs to the technical field of fixtures, and more specifically relates to a clamping device for special-shaped parts of a numerically controlled lathe. Background technique [0002] The sleeve currently produced is different from ordinary cylindrical sleeve parts in that its two ends are bell mouths, which belong to special-shaped parts. The two ends are thicker than the middle section, which brings difficulties to the CNC car clamping. [0003] For example, the application number: CN201620418148.1 The present invention relates to a numerical control processing equipment, in particular to an automatic clamping fixture of a numerical control lathe. The technical solution is as follows: an automatic clamping fixture for a numerically controlled lathe, including at least two clamping claws and a mounting plate, a space for clamping a workpiece that can be opened and closed is provided between each clamping claw, and the clamping claw inc...
