Abstract
Description
Technical field
The utility model belongs to machining technique with the apparatus field, is specifically related to a kind of simple in structurely, easy and simple to handle, can effectively keep the clamping device of shell inner hole of workpiece machining accuracy.
Background technology
On lathe, during processing technology thin-wall circular tube kind part, no matter being car outer rim or bore hole, is all more difficult, the especially processing of endoporus.This be due in working angles because the radial rigidity of getting instant result is very low, under cutting force, the effect of clamping power, very easily produce flexural deformation, thereby cause occurring oval or the large kidney-shaped phenomenon in middle little both sides.In addition, such part, owing to adding the poor radiation in man-hour, also very easily produces distortion, makes size and form and position tolerance not reach drawing requirement.In order to address this problem, except the rigidity of taking to improve process system, select rational cutting data, the measure such as fully cooling, matter of utmost importance to be solved is to reduce the impact of the suffered non-homogeneous radial load of workpiece on workpiece deformation, and because installation way is improper, cause often the problem place of the distortion of thin wall cylinder parts, severe patient even can cause the breakage of part to scrap.For this reason, develop a kind of simple in structurely, easy and simple to handle, process reliable and stablely, the clamping device that can effectively keep shell inner hole of workpiece machining accuracy is the key addressed this problem.
The utility model content
It is a kind of simple in structure, easy and simple to handle that the purpose of this utility model is to provide, and working stability is reliable, can effectively keep the clamping device of shell inner hole of workpiece machining accuracy.
The purpose of this utility model is to realize like this, comprise supporting base, clamping device, on described supporting base, anchor ear device is set, described clamping device comprises moving anchor ear and quiet anchor ear, described moving anchor ear and quiet anchor ear are oppositely arranged, and both are by the affixed cooperation of screw rod.
The utility model adopts static-dynamic anchor ear fit structure, is equivalent to add equably a prestressing force in shell workpiece periphery, makes piece-holder stressed more even, has solved thin-wall workpiece easily because being subject to the inhomogeneous problem on deformation caused of chucking power.On moving anchor ear, connecting handle is set, is easy for installation and removal.The utility model is simple in structure, utilizes the pre-embedded bolt fit structure, ensured integrally-built firm, working stability, safe and reliable; Not only operation is easier, quick for installation, and has effectively guaranteed dimensional accuracy and the yield rate of processing work.
The accompanying drawing explanation
Fig. 1 is the utility model overall structure and working state schematic representation;
In figure: 1-moves anchor ear, 2-Connection Block, the quiet anchor ear of 3-, 4-rest pad, 5-supporting base, 6-T type draw-in groove, 7-setscrew nut, 8-screw rod, 9-locking nut, 10-workpiece.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail, but never in any form the utility model is limited, and any conversion of doing based on the utility model, all fall into the utility model protection domain.
As shown in Figure 1, the utility model comprises supporting base 5, clamping device, on described supporting base 5, clamping device is set, and described clamping device comprises moving anchor ear 1 and quiet anchor ear 3, and described moving anchor ear 1 and quiet anchor ear 3 are oppositely arranged, and both are by the affixed cooperation of screw rod 8.
Described quiet anchor ear 3 is arranged on supporting base 5.
Between described quiet anchor ear 3 and supporting seat 5, rest pad 4 is set.
Described rest pad 4 is wedge shape, is symmetrical arranged, to adapt with quiet anchor ear 3 outer rims.
Described moving anchor ear 1 both sides correspondence arranges Connection Block 2.
Described Connection Block 2 is " L " type structure, and the connecting hole corresponding with supporting base 5 is set on it.
Between described Connection Block 2 and supporting base 5, by screw rod 8, connect.
Described moving anchor ear 1 and quiet anchor ear 3 are semi-annular shape, and the two internal diameter and workpiece 10 outer rims adapt.
Described screw rod 8 lower ends coordinate with setscrew nut 7 lockings in the T-shaped draw-in groove 6 that defaults in workbench.
Also be provided with the locking nut 9 matched with supporting seat 5, setscrew nut 7 on described screw rod 8, jointly to coordinate, the utility model be locked on the workbench of lathe.
Operation principle of the present utility model and the course of work:
The utility model adopts static-dynamic anchor ear fit structure, is equivalent to add equably a prestressing force in shell workpiece periphery, makes piece-holder stressed more even, has solved thin-wall workpiece easily because being subject to the inhomogeneous problem on deformation caused of chucking power.On moving anchor ear, Connection Block is set, is easy for installation and removal.During work, will need processing work to be horizontally placed on quiet anchor ear, press clamping shown in accompanying drawing 1, then adjust moving anchor ear compression, calibration of workpieces, upper end mill head, can carry out other operation.
