Description

High precision grinding inner hole clamp
Technical field
The utility model relates to a kind of grinding machine fixture, specifically a kind of high precision grinding inner hole clamp, belongs to component of machine processing technique field.
Background technology
In prior art, the parts fixation mode that general-purpose grinder is conventional when carrying out grinding endoporus to part has three-jaw clamping, four paws clamping and the clamping of T-shaped dish etc.When there being concentricity requirement to the endoporus of grinding and cylindrical, just need to need check and correction part benchmark cylindrical when clamping, the existing installation way cycle is long, and every grinding part all needs again to proofread, not only production efficiency is very low, and machining accuracy also cannot be guaranteed, and qualification rate is low.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, provides a kind of high precision grinding inner hole clamp, and its structure is simple, and reasonable in design, convenient mounting and clamping, can enhance productivity greatly, improves machining accuracy.
Technical scheme according to the utility model provides: high precision grinding inner hole clamp, it is characterized in that: comprise pull bar, clamp body, collet and locking nut, described clamp body is for loading in grinding machine spindle endoporus, and the Morse's taper of the Morse's taper of clamp body outer surface and grinding machine spindle endoporus is adaptive; Described pull bar is contained in clamp body rear end, and it is concrete that pull bar is used for strain clamp; In the chamber that described collet is assemblied in clamp body front end and with locking nut locking, collet is used for clamping part to be processed.
As further improvement of the utility model, described collet adopts ER series of spring clips head or SD series of spring clips head.
As further improvement of the utility model, the diameter of part clamping range of described ER series of spring clips head is φ 2mm-φ 34mm, and the diameter of part clamping range of SD series of spring clips head is φ 2mm-φ 25mm.
As further improvement of the utility model, when the endoporus of grinding and the concentricity requirement of cylindrical are 0.01mm-0.02mm, described collet adopts ER series of spring clips head; When the endoporus of grinding and the concentricity requirement of cylindrical are 0.005mm-0.01mm, described collet adopts SD series of spring clips head.
As further improvement of the utility model, for being threaded between described pull bar clamp body, the precession depth adjustable of pull bar in clamp body.
compared with prior art, tool has the following advantages the utility model:
(1) structure is simple, reasonable in design, greatly can enhance productivity, cut down finished cost.
(2) parts fixation is convenient, reliable, and repetitive positioning accuracy is high, can improve machining accuracy.
(3) with machine tool chief axis with the use of clamp body and with clamp body with the use of collet be all removable, can the part kind of grinding many, applied widely.
Accompanying drawing explanation
Fig. 1 is structure and the applicable cases schematic diagram of the utility model embodiment.
Detailed description of the invention
Below in conjunction with concrete drawings and Examples, the utility model is described in further detail.
As shown in the figure: the high precision grinding inner hole clamp in embodiment is formed primarily of parts such as pull bar (1), clamp body (3), collet (4) and locking nuts (5).
As shown in Figure 1, described clamp body (3) is for loading in grinding machine spindle (2) endoporus, and the Morse's taper of the Morse's taper of clamp body (3) outer surface and grinding machine spindle (2) endoporus is adaptive; Described pull bar (1) is contained in clamp body (3) rear end, and pull bar (1) is for strain clamp concrete (3); The chamber that described collet (4) is assemblied in clamp body (3) front end is interior also with locking nut (5) locking, and collet (4) is for clamping part to be processed (6).
In the utility model, described collet (4) can adopt ER series of spring clips head (4) or SD series of spring clips head (4).Part (6) the diameter clamping range of described ER series of spring clips head (4) is φ 2mm-φ 34mm, and part (6) the diameter clamping range of SD series of spring clips head (4) is φ 2mm-φ 25mm.When the endoporus of grinding and the concentricity requirement of cylindrical are 0.01mm-0.02mm, described collet (4) adopts ER series of spring clips head (4); When the endoporus of grinding and the concentricity requirement of cylindrical are 0.005mm-0.01mm, described collet (4) adopts SD series of spring clips head (4).
As shown in Figure 1, in the utility model embodiment, for being threaded between described pull bar (1) clamp body (3), the precession depth adjustable of pull bar (1) in clamp body (3).
During embody rule, clamp body (3) is filled in [different types of grinding machine spindle (2) Morse's taper is different, then process the clamp body (3) of different Morse's taper according to grinding machine] in grinding machine spindle (2), operation pull bar (1) strain clamp concrete (3); Be contained in collet (4) by processed part (6), locking nut (5) screws and is fixedly clamped by part to be processed (6).Like this for the part (6) having batch machining, without the need to proofreading benchmark cylindrical during each grinding, reloading the loading of a part (6) as long as locking nut (5) is screwed out, shortening process time, improve production efficiency, cut down finished cost.
