Description
Technical field
The present invention relates to a kind of anchor clamps of lathe, be specifically related to a kind of Digit Control Machine Tool anchor clamps of clamping thin cylinder.
Background technology
At present, the thin cylinder part is widely used in machining and field such as life production etc., and it has in light weight, compact conformation, advantage such as little takes up room.But the machining accuracy of thin cylinder class part is wayward: this type part is used machined into usually, and its main processes is: 1) planar end surface, thick thorax hole; 2) rough turn cylindrical; 3) smart thorax hole; 4) finish turning cylindrical; 5) planar end surface.The problem that faces in the prior art is: problems such as cylindrical and endoporus often appear in this type of part after turning coaxiality deviation is big, the circularity of endoporus and cylindrical and cylindricity are overproof.
Traditional anchor clamps comprise three-jaw card etc., have used the clamping cylinder, damage cylinder outer wall easily.Though also have the fixing anchor clamps of some point that adopts rigidity contacts,,, all can make workpiece produce incomparable inconsistent strain because clamping sum of errors clamping force is inhomogeneous no matter be circle or cylindrical in fixing; In addition; The point contact is fixing also can to make heat in metal cutting conduct unbalanced generation thermal deformation difference; Cause workpiece after completion of processing unloads from anchor clamps; Can cause its internal stress redistribution because cancelling external force and inhomogeneous cooling, workpiece produces secondary deformation, reduces the machining accuracy of thin cylinder part greatly.
Summary of the invention
Goal of the invention: in order to overcome the deficiency that exists in the prior art; The present invention provides a kind of Digit Control Machine Tool anchor clamps with ball and elastic groove; These anchor clamps can not damage cylinder outer wall in the process of clamping thin cylinder; And in the thin cylinder process, thin cylinder can not be out of shape, and the thin-walled crudy is good.
Technical scheme: for realizing above-mentioned purpose; A kind of Digit Control Machine Tool anchor clamps of the present invention with ball and elastic groove; Comprise the workpiece clamping body, be positioned at workpiece clamping body head connector, be positioned at first locking body on the workpiece clamping body afterbody peripheral circumferential, be positioned at second locking body on the peripheral circumferential of workpiece clamping body middle part; The outward-dipping formation tapering of the outer wall inclined-plane of said workpiece clamping body afterbody, the inwall of the first locking body afterbody are provided with and the suitable tapering inclined-plane of workpiece clamping body afterbody; Second locking body and workpiece clamping body are through being threaded, and the second locking body periphery is provided with the control crank bar; Described workpiece clamping body afterbody along the circumferential direction is interval with the strip elastic groove.
The number of said strip elastic groove is 12, and 12 strip elastic grooves along the circumferential direction evenly distribute; The degree of depth of each strip elastic groove is 75mm, and width is 2 mm.
Described first locking body and the contacted endface position of second locking body are provided with movable steel ball.
The number of described steel ball is six, and the circumference of six movable steel ball edge second locking bodies evenly distributes.
The number of said control crank bar is three, and three control crank bars evenly distribute along second locking body is peripheral.
Beneficial effect: a kind of Digit Control Machine Tool anchor clamps of the present invention with ball and elastic groove; Structure is ingenious, through at workpiece clamping body afterbody elastic groove being set, and clamping external enclosing at workpiece and puts first locking body and second locking body; Can be so that clamping and lock the thin cylinder workpiece and be unlikely to cause the thin cylinder workpiece deformation or damage the workpiece outer wall; Requirement when satisfying processing thin-walled cylindrical workpieces guarantees the crudy of thin cylinder, improves the working (machining) efficiency of thin cylinder workpiece; Can avoid occurring defect ware, can reduce production costs and improve the performance of enterprises.
Description of drawings
Fig. 1 is a Digit Control Machine Tool clamp structure sketch map of the present invention.
The specific embodiment
Below in conjunction with accompanying drawing the present invention is done explanation further.
As shown in Figure 1; A kind of Digit Control Machine Tool anchor clamps of the present invention with ball and elastic groove; Comprise workpiece clamping body 2, be positioned at workpiece clamping body 2 heads connector 1, be positioned at first locking body 5 on the workpiece clamping body 2 afterbody peripheral circumferential, be positioned at second locking body 3 on the workpiece clamping body 2 middle part peripheral circumferential; The outward-dipping formation tapering of the outer wall inclined-plane of workpiece clamping body 2 afterbodys, the inwall of first locking body, 5 afterbodys are provided with and the suitable tapering inclined-plane of workpiece clamping body 2 afterbodys; Second locking body 3 and workpiece clamping body 2 are through being threaded, and second locking body, 3 peripheries are provided with control crank bar 4; Described workpiece clamping body 2 afterbodys along the circumferential direction are interval with strip elastic groove 7.
Wherein, the degree of depth and the width of the number of strip elastic groove 7, each strip elastic groove 7 can be selected according to user demand, and for example, the number of strip elastic groove 7 can be 3 ~ 16, is preferably 6,8,12; The degree of depth is 50 ~ 90mm, is preferably 60 mm, 65mm, 70mm, 75mm, 80mm; Width is 1.5 ~ 3.5 mm, is preferably 2 mm, 2.5 mm.
In the present embodiment, the number of strip elastic groove 7 is 12, and 12 strip elastic grooves 7 along the circumferential direction evenly distribute; The degree of depth of each strip elastic groove 7 is 75mm, and width is 2 mm.First locking body 5 and second locking body, 3 contacted endface position are provided with movable steel ball 6.The number of movable steel ball 6 is six, and the circumference of six movable steel ball 6 edges second locking bodies 3 evenly distributes.The number of control crank bar 4 is three, and three control crank bars 4 are along the 3 peripheral evenly distributions of second locking body.Workpiece clamping body 2 firmly is connected through bolt 8 or screw with connector 1.
The present invention in use; At first correct sectional fixture is held operating grip bar 4 second locking body 3 is pushed away semi-circumference to workpiece clamping body 2 cephalad direction, and workpiece clamping body 2 is promptly at relaxation state; Begin clamping workpiece this moment; In the time of in workpiece correctly is placed in workpiece clamping body 2, holds control crank bar 4 second locking body 3 is rotated semi-circumference to workpiece clamping body 2 caudal directions, can will be held workpiece locking.
