Abstract

A mechanical clamping spring collet for holes comprises a clamp body, wherein one end of the clamp body is provided with a boss. The outer circumference of the boss is evenly provided with a plurality of grooves, tensioning blocks are arranged in the grooves, and an end face of the boss is provided with a tensioning device for tensioning the tensioning blocks. When the mechanical clamping spring collet for the holes is used, the collet is fixed on a spindle of a lathe through screws, workpieces are installed and fixed on the clamp body through limit screws, then inner holes of tensioning workpieces of tensioning bolts are rotated to position and clamp the workpieces, and accordingly processing can be performed. After processing, the workpieces can be demounted by rotating the tensioning bolts reversely.

Description

A kind of hole mechanical grip collet
Technical field
The utility model relates to a kind of mechanical grip frock, relates in particular to a kind of hole mechanical grip collet, is used for excircle of workpiece and end face semifinishing and fine finishining, belongs to technical field of mechanical manufacturing equipment.
Background technology
China was manufacturing in recent years develops the development that has spurred machining tool and tool-making rapidly, numerical control machining center and hydraulic pressure, air-actuated jaw obtain widely applying, but machinery manually clamping device simple in structure because of it, do not need external power, use cost is low still obtains widely applying in certain occasion.
This type of hole with mechanical grip collet structure as shown in Figure 1 in the past, comprise a chuck body 1, at chuck body 1 and tensioner bolt 2, as shown in Figure 2, evenly have three axial grooves on the end face of chuck body 1 and form three tensioner lobe 7 double as tensioner elements through Quenching Treatment simultaneously, the position that is positioned at three tensioner lobe 7 centers on the chuck body 1 is provided with screw 8, is provided with tensioner bolt 2 in the screw 8.
The anchor clamps using method for this chuck to be fixed on the lathe spindle by screw, load onto workpiece to be processed 6 and tighten the endoporus that makes tensioner lobe 7 tensioner workpiece 6, and locate and clamp in conjunction with stop screw 3 by tensioner bolt 2.Because it is simultaneously axially grooved that tensioner lobe 7 parts of chuck body 1 need be carried out Quenching Treatment, radial deformation is inhomogeneous and uncontrollable after the heat treatment, tensioner lobe part owing to rotation produces the actual quick condition that is in of centrifugal force, makes the processed workpiece form and position tolerance not reach the drawing requirement in workpiece processing simultaneously; Simultaneously, chuck body 1 double as tensioner element, fragile integral replacing, the use cost height of needing in the use.
The utility model content
Problem to be solved in the utility model provides a kind of hole of satisfying workpiece Geometrical Tolerance Principle, long service life mechanical grip collet frock.
In order to address the above problem, the utility model by the following technical solutions:
A kind of hole mechanical grip collet comprises:
Chuck body, an end of chuck body has boss;
Evenly be provided with several grooves on the excircle of described boss;
Tightening piece is installed in groove,
The end face of described boss is provided with and is used for the swelling device of tensioner tightening piece.
Following the utility model is to the further improvement of former such scheme:
A wherein end of described tightening piece is fixedlyed connected with boss, and the other end is projected into the outside of raised head face, and its end is provided with inwardly protruded lug boss, and lug boss is a pyramidal structure.
Further improve:
The tensioner bolt of described swelling device for being threaded with boss.
Further improve:
Described tensioner bolt has the afterbody of a taper that matches with lug boss;
Making the tightening piece footpath outwards move tensioner workpiece endoporus by rotation tensioner bolt locatees and clamps.
Further improve:
The quantity of described tightening piece is three.
Further improve:
The end face of described boss has the groove to the end face sunken inside;
Bottom at this groove has screw;
The tensioner bolt is threaded with screw.
Further improve:
Described chuck body is provided with the stop screw that is used for fixing workpiece.
During use, this chuck is fixed on the lathe spindle by screw, load onto workpiece, and workpiece is fixed on the chuck body by stop screw, after making workpiece location and clamping by the endoporus that rotates tensioner bolt tensioner workpiece then, just can process, completion of processing, reverse rotation tensioner bolt just can unload workpiece.
The utility model separates chuck body and tightening piece, further process again after the assembling of processing back separately separately, tightening piece carries out Quenching Treatment separately as the tensioner element, can change separately as consumable accessory, the anchor clamps life-span is extended greatly, practical reliable, use the workpiece accuracy of this chuck processing to satisfy drawing and instructions for use fully, anchor clamps intensity has obtained enhancing, improve and improved more than 3 times service life, chuck body changes monoblock type into, has eliminated floating in the clamp body work simultaneously, makes the Geometrical Tolerance Principle after frock can satisfy workpiece processing.
The utility model is described in further detail below in conjunction with accompanying drawing with embodiment.
