Description

A kind of hydraulic pressure holding device
Technical field
Field of machining is the utility model is related to, a kind of hydraulic pressure holding device is related to by it.
Background technology
Deep hole machining occupies very important status in field of machining, accounts for the 40% of hole machined amount.With section The progress of technology, the emergence of novel high-strength, high rigidity and high value difficulty deep hole processing part, workpieces processing are being processed The continuous improvement required in depth, machining accuracy and processing efficiency so that deep hole machining becomes the critical process of mechanical processing And processing difficulties.Traditional processing method is increasingly difficult to meet or even not reach present deep hole machining in precision, effect at all Requirement in rate, material.
Utility model content
In order to preferably adapt to the needs of modern processing, the utility model provides a kind of hydraulic pressure holding device.
Embodiment:
A kind of hydraulic pressure holding device, including oil cylinder, compacting part and circuit parts, oil cylinder are located at the top of compacting part, Circuit parts are located at compacting part side, it is characterised in that:The compacting part include mandril, auxiliary device, column, pressing sleeve, Hold assembly, the mandril upper end are equipped with spill deep hole, and lower end is provided with deep hole, are set on the compacting part at end floor beam center Hole is equipped with, is used to place piston in hole, the length of the piston is identical with the depth of mandril upper end spill deep hole, described auxiliary Device is helped to be fixed on column, the hold assembly is arranged on the base of compacting part.
Further, the both sides of the auxiliary device are fixed on column across mandril with nut, the auxiliary device Side set two quarter butts from mandril another side stretch out.
Further, the pressing sleeve is up-narrow and down-wide, the width of pressing sleeve top narrower part and the width of mandril lower end deep hole Identical, the height of pressing sleeve top narrower part is identical with the depth of mandril lower end deep hole.
Further, the central axes of the mandril are overlapped with the central axes of hold assembly.
The beneficial effects of the utility model:Oil cylinder is set on the utility model, is acted on using in-oil cylinder oil pressure and promotes top Bar moves downward, so as to compress the part of clamped member grip, improves the efficiency of mechanical processing, simplifies mechanical structure, Make operating process more simple and effective.
Brief description of the drawings
Fig. 1 is the diagrammatic cross-section of the utility model;
Fig. 2 is the overall structure diagram of the utility model.
Embodiment
Specific embodiment of the present utility model is described in detail below in conjunction with the accompanying drawings.
As depicted in figs. 1 and 2, a kind of hydraulic pressure holding device, including oil cylinder 1, compacting part 2 and circuit parts 3, oil cylinder 1 Positioned at the top of compacting part 2, circuit parts 3 are located at 2 side of compacting part, it is characterised in that:The compacting part 2 includes top Bar 4, auxiliary device 5, column 6, pressing sleeve 7, hold assembly 8,4 upper end of mandril are equipped with spill deep hole 9, and lower end is provided with deep hole 10, hole 11 is set at end floor beam center on the compacting part 2, is used to place piston 12, the piston 12 in hole 11 Length it is identical with the depth of 4 upper end spill deep hole 9 of mandril, the auxiliary device 5 is fixed on column 6, the clamping part Part 8 is arranged on the base of compacting part 2.
The both sides of the auxiliary device 5 are fixed on column 6 across mandril 4 with nut, the side of the auxiliary device 5 Two quarter butts 13 are set to be stretched out from mandril another side.
The pressing sleeve 7 is up-narrow and down-wide, the width of 7 top narrower part of pressing sleeve and being of same size for 4 lower end deep hole 10 of mandril, The height of 7 top narrower part of pressing sleeve is identical with the depth of 4 lower end deep hole 10 of mandril.
The central axes of the mandril 4 are overlapped with the central axes of hold assembly 8.
Hold assembly in the utility model tightly clamps part, and 4 top of mandril is provided with piston 12, and 12 top of piston is Oil cylinder 1, under the action of oil pressure, piston 12, which moves down, promotes dynamic mandril 4 to hold out against the part that clamped component 8 clamps downwards, described Auxiliary device 5 is to ensure that the central axes of mandril 4 are overlapped with the central axes of hold assembly 8, so as to accurate compressing component.
The advantages of basic principle, main feature and the utility model of the utility model has been shown and described above.This reality It is not restricted to the described embodiments with new, the above embodiments and description only describe the original of the utility model Reason, the utility model also has various changes and modifications on the premise of not departing from the spirit and scope of the utility model, these changes Change and improve and both fall within claimed the scope of the utility model.The utility model requires protection scope is by appended right Claim and its equivalent define.
