Abstract

A kind of turning clamp, the axle sleeve that it comprises locating shaft and is connected as a single entity with locating shaft, blind flange is installed with at the oral area bolt of the inner unthreaded hole of axle sleeve, internal thread hole is shaped with in blind flange centre, a piston is set in the unthreaded hole of axle sleeve, bowl-type spring is provided with between piston and blind flange, at piston and axle sleeve be marked with liquid plastics in the unthreaded hole closed, the axle sleeve in liquid plastics interval arranges a screw, and the utility model has the advantage that the quick and easy clamping force of clamping work pieces is comparatively large, can not destroy screw thread.

Description

A kind of turning clamp
Technical field
The utility model relates to a kind of turning clamp, and particularly relate to a kind of threaded portion being used for holding workpiece, the turning clamp of cutted thread end working position, belongs to turning clamp technical field.
Background technology
As everyone knows; in Tutrning Process; often can run into some with the workpiece having screw thread handle, this kind of workpiece processes thread handle prior to other working position in process, clamps afterwards and process threaded shanks on lathe; then other position is processed; owing to processing screw thread in such cases, when with the thread handle clamping processed, often double thread is causing certain destruction; to this, also there is no good way at present.
Summary of the invention
The purpose of this utility model is: provide a kind of turning clamp, is used for specially clamping some with the workpiece having screw thread handle, and other position is carried out to the fixture of turning.
A kind of turning clamp described in the utility model, the axle sleeve that it comprises locating shaft and is connected as a single entity with locating shaft, described axle sleeve inside is shaped with unthreaded hole, blind flange is installed with at end, the aperture bolt of unthreaded hole, internal thread hole is shaped with in blind flange centre, a piston is set in the unthreaded hole of axle sleeve, bowl-type spring is provided with between piston and blind flange, at piston and axle sleeve be marked with liquid plastics in the unthreaded hole closed, the axle sleeve in liquid plastics interval arranges a screw, and described screw end gos deep into liquid plastics interval.
Operation principle of the present utility model is: be screwed in the middle internal thread hole of blind flange by needing the threaded shanks of processing work, make head and the piston contact of the threaded shanks of workpiece, now, tighten screw, because screw makes liquid plastics expand, described in, piston is just moved, piston holds out against the head of threaded shanks, thus makes workpiece be in clamped condition.
Beneficial effect: the utility model, due to after employing said method, not only has the advantage that clamping work pieces is quick and easy, meanwhile, also has the advantage that clamping force is comparatively large, can not destroy screw thread.
Accompanying drawing explanation
Accompanying drawing 1 is structural representation of the present utility model;
Shown in Fig. 1: 1, position axle; 2, axle sleeve; 3, screw; 4, liquid plastics; 5, piston; 6, bowl-type spring; 7, bolt; 8, blind flange; 9, unthreaded hole; 10, workpiece.
Detailed description of the invention
By reference to the accompanying drawings 1, detailed description of the invention of the present utility model is:
Its axle sleeve (2) of comprising locating shaft (1) and being connected as a single entity with locating shaft (1) of the utility model, in the process manufactured, by the structure that locating shaft (1) and axle sleeve (2) are made of one,
Unthreaded hole (9) is shaped with in axle sleeve (2) inside, to ensure that there is higher coaxial accuracy between unthreaded hole (9) and locating shaft (1), blind flange (8) is installed with in the end, aperture bolt (7) of unthreaded hole (9), internal thread hole is shaped with in blind flange (8) centre, the precision of processing parts in order to ensure, the internal thread hole of blind flange (8) central part should have higher coaxial accuracy with locating shaft, a piston (5) is set in the unthreaded hole (9) of axle sleeve (2), bowl-type spring (6) is provided with between piston (5) and blind flange (8), at piston (5) and axle sleeve (2) be marked with liquid plastics (4) in the unthreaded hole (9) closed, the axle sleeve (2) that liquid plastics (4) is interval arranges a screw (3), it is interval that liquid plastics (4) is goed deep in described screw (3) end.
When using the utility model, the locating shaft (1) of the utility model device is clamped in three of lathe to grab on chuck or directly and be connected with the main shaft of lathe, be screwed in the middle internal thread hole of blind flange (8) by needing the threaded shanks of processing work (10), the head of the threaded shanks of workpiece (10) is contacted with piston (5), now, tighten screw (3), because screw (3) makes liquid plastics expand, described, piston (5) is just moved, piston (5) holds out against the head of threaded shanks, thus make workpiece (10) be in clamped condition, now, namely processing can be carried out to workpiece.
