Description

A kind of clamping device that is used for the processing of revolving body surface hole
Technical field:
The utility model relates to a kind of clamping device, particularly a kind of clamping device that is used for the processing of revolving body surface hole.
Background technology:
Revolving body is adding man-hour, often need carry out hole processing such as hole milling, boring on the surface.At present, the clamping device that is used for the processing of revolving body surface hole generally adopts V-block to support the middle part of revolving body, this kind form is for the revolving body of processing different-diameter, support in the middle of it and be difficult to guarantee clamp the position concentric with two ends, and V-block can not clamping work pieces, and machining accuracy is difficult to guarantee; Simultaneously, existing clamping device, two ends all adopt tail spindle to clamp, and its positioning accuracy is lower, and it is less to clamp activity, and is not quick detachable after part is loaded onto, and for batch machining, the processing uniformity is poor, and production efficiency is lower.
Summary of the invention:
The utility model has overcome deficiency of the prior art, provide a kind of simple in structure, clamping precision is high, workpiece convenient disassembly, production efficiency height, can be used for the clamping device of different-diameter revolving body surface hole processing.
In order to solve the problems of the technologies described above, the utility model is achieved through the following technical solutions:
A kind of clamping device that is used for the processing of revolving body surface hole, holding out against end by inwall tensioner end, middle clamping bracing frame and activity forms, the middle bracing frame that clamps holds out against between the end at inwall tensioner end and activity, and wherein, inwall tensioner end is made up of gyroaxis and the tensioner cover that is enclosed within its axle head; Middle clamp bracing frame by about two movable supporting frames forms, two V-type framves of being made up of ball bearing are installed on the movable supporting frame of the left and right sides axisymmetrically by adjustment; Activity hold out against end by lifting axe with hold out against axle bed and form, it is installed on the guide rail of workbench base plate, and connects with cylinder.
For ease of the tensioner degree of control, the adjustment stopping means is set at inwall tensioner end to revolving body.
For guaranteeing the gyroaxis concentric of lifting axe and inwall tensioner end, the described axle bed lower surface that holds out against is set to the inclined-plane, and the voussoir that upper surface is the inclined-plane thereunder is set.
Compared with prior art, the beneficial effects of the utility model are:
(1) but in the middle of clamp the bearing height free adjustment of bracing frame, can be used for the clamping of different-diameter revolving body, and left and right sides V-type frame can clamp part, guaranteed higher processing precision;
(2) inwall tensioner end adopts tensioner cover tensioner part, and its tensioner activity is bigger, the part convenient disassembly, and the efficient height carries out the end face location by stopping means and tensioner cover to part simultaneously, the positioning accuracy height, the processing high conformity is fit to the clamping of producing in batches.
Description of drawings:
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is a cross-sectional view of the present utility model;
Fig. 3 is the structural representation of clamping bracing frame of the present utility model;
The specific embodiment:
Below in conjunction with the accompanying drawing and the specific embodiment the utility model is described in further detail:
In conjunction with illustrated in figures 1 and 2, the clamping device that is used for the processing of revolving body surface hole holds out against end 3 by inwall tensioner end 1, middle clamping bracing frame 2 and activity and forms.
Inwall tensioner end 1 is made up of gyroaxis 11 and tensioner cover 12, and tensioner cover 12 is placed in gyroaxis 11 axle heads; Simultaneously stop screw 13 is set, adjusts the fitting limit of length controlled system tensioner cover 12 with the gyroaxis 11 of stop screw 13, thereby control tensioner degree revolving body in the position of overlapping 12 end faces with respect to tensioner of inwall tensioner end 1.
Activity holds out against end and 3 is installed on the guide rail 5, and connects with cylinder 4, and cylinder 4 can be controlled movable top and tightly hold 3 to move along guide rail 7; As shown in Figure 2, activity holds out against end 3 by lifting axe 31 with hold out against axle bed 32 and forms, is gyroaxis 11 concentrics that guarantee in lifting axe 31 and the inwall tensioner end 1, and the lower surface that holds out against axle bed 32 is set to the inclined-plane, and the voussoir 33 that upper surface is the inclined-plane thereunder is set.
The middle bracing frame 2 that clamps holds out against between the end 3 at inwall tensioner end 1 and activity.As shown in Figure 3, middle clamp bracing frame 2 by about two movable supporting frames 21 form, movable supporting frame 21 is installed on the T type bottom land seat 23, can move along T type groove; Two V-type framves of being made up of ball bearing 22 are installed on the left and right sides movable supporting frame 21 axisymmetrically by adjusting.
During the clamping revolving body workpieces, at first regulate the bearing height that holds out against height and rolling wheel support 22 of lifting axe 31, guarantee that inwall tensioner end 1, middle clamping bracing frame 2 and activity hold out against end 3 three part concentrics; Then revolving body is put between middle two movable supporting frames 21 that clamp in the bracing frame 2 that unclamped, and the one end is placed on the tensioner cover 12, cylinder 4 work, promote the other end jack-up of lifting axe 31 with revolving body, part is along with lifting axe 31 carries out moving of axial little stroke under the effect of cylinder 4, and the inner conical surface that promotes tensioner cover 12 closely cooperates with the male cone (strobilus masculinus) of gyroaxis 11, and tensioner is overlapped 12 and strutted, with the revolving body tensioner; The movable supporting frame 21 that slides then, two V-type framves 22 support and clamp part about making, and at last movable supporting frame 21 are locked, and this moment, part was clamped fully.
