Abstract
The utility model relates to a high accuracy thin wall deep hole valve barrel centre gripping frock, it includes mount pad (1) at rear, its characterized in that be provided with annular centre gripping cover on mount pad (1), annular centre gripping cover comprises three centre gripping cover segmentation (2), leaves the clearance between the three centre gripping cover segmentation (2), centre gripping cover segmentation (2) is including construction section (2.2) in the 13 ring covers (2.1) and 13 ring cover (2.1) the outsides, construction section (2.2) two at least fixing bolt (3) and mount pad (1) fixed connection through radially arranging. The utility model discloses contact earlier during with traditional centre gripping improves to the face contact, has increased the lifting surface area for the clamping is stable during with the processing of car generation mill, and the clamping is out of shape for a short time, solves thin wall deep hole valve barrel with the yielding hole that results in in man -hour precision oval and that the bore depth results in is low, the roughness is low, and realize the hole and the closed angle of step face and locate no burr, reach sealed requirement.
Description
Technical field
The utility model relates to a kind of high accuracy thin wall and deep hole valve pocket clamping tooling.
Background technology
At present, the main dependence on import of domestic high-end hydraulic pressure valve pocket, by the restriction of design of part and existing processing mode, cylindrical Φ 60mm, endoporus Φ 44mm, hole depth is difficult to reach drawing requirement more than the deep hole thin wall component endoporus of 90mm, and the endoporus abroad for meeting this type of part requires also to use expensive high accuracy inner circle mill; My department by the experiment of equipment, frock, technique and improvement, to realize with car for mill technology processing endoporus to 0.003mm cylindricity and 0.0013mm circularity, Ra0.3 μm roughness; And realize the sharp corner impulse-free robustness of endoporus and step surface, reach seal request.In previous experiments process, find that the part circularity processed is always bad, by analysis, reason is because part external diameter is larger greatly, frock retaining part is incomplete, produce in process caused by distortion, therefore seek a kind of clamping to stablize, the high accuracy thin wall and deep hole valve pocket clamping tooling that clamping deformation is little is particularly important.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, provides one to make to stablize with clamping during car generation mill processing, the high accuracy thin wall and deep hole valve pocket clamping tooling that clamping deformation is little.
The purpose of this utility model is achieved in that
A kind of high accuracy thin wall and deep hole valve pocket clamping tooling, it comprises the mount pad at rear, it is characterized in that described mount pad is provided with ring gripping cover, described ring gripping cover is made up of three retaining sleeve segmentations, gap is left between three retaining sleeve segmentations, described retaining sleeve segmentation comprises the construction section outside 1/3 ring set and 1/3 ring set, and described construction section is fixedly connected with mount pad by least two set bolts of radial arrangement.
Compared with prior art, the beneficial effects of the utility model are:
First contact when tradition clamps by the utility model high accuracy thin wall and deep hole valve pocket clamping tooling is improved to face contact, increase lifting surface area, make to stablize with clamping during car generation mill processing, clamping deformation is little, solves thin wall and deep hole valve pocket and adds that the inner hole precision that the oval and hole depth of the yielding endoporus caused in man-hour causes is low, roughness is low; And realize the sharp corner impulse-free robustness of endoporus and step surface, reach seal request.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model high accuracy thin wall and deep hole valve pocket clamping tooling.
Fig. 2 is the A-A sectional view of Fig. 1.
Wherein:
Mount pad 1
Retaining sleeve segmentation 2,1/3 ring set 2.1, construction section 2.2
Set bolt 3.
Detailed description of the invention
See Fig. 1 and Fig. 2, a kind of high accuracy thin wall and deep hole valve pocket clamping tooling that the utility model relates to, it comprises the mount pad 1 at rear, described mount pad 1 is provided with ring gripping cover, described ring gripping cover is made up of three retaining sleeve segmentations 2, leave gap between three retaining sleeve segmentations 2, described retaining sleeve segmentation 2 comprises the construction section 2.2 outside 1/3 ring set 2.1 and 1/3 ring set 2.1, and described construction section 2.2 is fixedly connected with mount pad 1 by two set bolts 3 of radial arrangement.
During use, high accuracy thin wall and deep hole valve pocket is arranged in ring gripping cover, then construction section 2.2 is regulated to be installed on the position of mount pad 1, thus make the outer wall of the inwall locking high accuracy thin wall and deep hole valve pocket of three retaining sleeve segmentations 2, now between three retaining sleeve segmentations 2 and the outer wall of high accuracy thin wall and deep hole valve pocket, forming surface contacts, the retaining part of high accuracy thin wall and deep hole valve pocket clamping tooling increases, high accuracy thin wall and deep hole valve bush part stressed evenly.
Claims (1)
