Description
Technical field
It the utility model is related to machining field, and in particular to a kind of eccentric hoop car grinds internal clamp.
Background technology
The eccentric hoop inner bore surface roughness of sliding-vane pump requires high, only can not meet that precision will using turnery processing
Ask, it is necessary to which grinding is carried out after turnery processing can be only achieved required surface roughness, existing processing method is first will
Clamping workpiece carries out turnery processing on lathe, will then add by carrying out grinding on the clamping workpiece of turnery processing to grinding machine
Work, workpiece are needed by clamping twice, and due to lathe, the different clamping devices that it is used are also different with the operating principle of grinding machine, and
Two sleeve clamps can not meet two kinds of car, mill processing modes simultaneously, and clamping time and effort consuming, processing efficiency are low twice.
The content of the invention
The utility model discloses a kind of eccentric hoop car to grind internal clamp, and clamping is efficient and convenient, and clamped one time meets that car is ground
Two kinds of processing modes.
The further improvement project of the utility model is：
Eccentric hoop car grinds internal clamp, including the end plate being fixed on main shaft, and the outer face center of end plate, which is provided with, accommodates work
The detent of part, the axis of the main shaft and the centerline collineation of inner hole of workpiece, set on the end plate on the outside of the detent
There is the pressing plate of workpiece pressing, the pressing plate is bolted on the outer face of the end plate, the bottom land of the detent
Tool bore is provided with away, the hole wall of workpiece exceeds to walk the hole wall of tool bore.
The further improvement project of the utility model is that the cell wall of the detent is provided with two card convexs, two cards
The convex locating slot being provided with respectively with Workpiece periphery face is fixed.
The further improvement project of the utility model is, the pressing plate includes the fixed block of rectangle, before the bottom surface of fixed block
End, which is provided with, compresses projection, and bolt is threadedly coupled through the through hole that fixed block is provided with end plate, and the aperture of the through hole is more than spiral shell
The screw diameter of bolt, the compression projection are pressed on the end face of workpiece.
The further improvement project of the utility model is that the detent is exposed in the outer face of the workpiece.
The utility model has advantages below compared with prior art：
The utility model is simple in construction, and eccentric hoop is placed on the locating slot for making its both sides in detent and card convex engaging just
Step positioning, rotate pressing plate and it is compressed projection and push down the outer face of eccentric hoop then clamping screw, whole eccentric hoop are fixed on end
In the detent of plate, fixed form is firm, swift to operate, and eccentric hoop endoporus is conllinear with main shaft, during main axis endoporus and its
Rotate coaxially without departing from the center of circle, facilitate lathe tool to enter bistrique when interior hole machined, main shaft do not rotate and can also pass through endoporus and carry out inner circle
The attrition process of hole wall, clamped one time are adapted to two ways processing, improve production efficiency.

Embodiment
Eccentric hoop car mill internal clamp as shown in Figure 1, 2, including the end plate 2 being fixed on main shaft 1, the outer end of end plate 2
Face center is provided with the detent 3 for accommodating workpiece, and the profile of detent 3 is consistent with workpiece, and workpiece is put into detent, embedding
Enter end plate.The axis of main shaft 1 and the centerline collineation of the endoporus of workpiece 4, endoporus rotates not eccentric during main axis, is easy to bistrique 13
Feed and process with lathe tool.The end plate in the outside of detent 3 is provided with the pressing plate 5 of workpiece pressing 4, and pressing plate 5 is fixed on by bolt 6
On the outer face of end plate 2, briquetting axial compression workpiece, its movement, firm position are prevented.The bottom land of detent 3 is provided with feed
Hole 7, the hole wall of workpiece 4 exceed to walk the hole wall of tool bore 7, prevent tool feeding from bumping against with end plate, cutter and end plate are caused to damage.
In the present embodiment, the cell wall of detent 3 is provided with two card convexs 8, two card convexs 8 respectively with the outer peripheral face of workpiece 4
The locating slot 9 being provided with is fixed, and is positioned on circumferencial direction, prevents workpiece from rotating.Pressing plate 5 includes the fixed block 10 of rectangle,
The bottom surface front end of fixed block 10, which is provided with, compresses projection 11, and bolt 6 connects through the through hole 12 that fixed block 10 is provided with and the screw thread of end plate 2
Connect, the aperture of through hole 12 is more than the screw diameter of bolt 6, and the compression projection 11 is pressed on the end face of workpiece 4, unclamps bolt
Briquetting can rotate around screw rod, so as to conveniently be placed and taken out workpiece, clamping screw briquetting axial compression workpiece.Workpiece 4
The detent 3 is exposed in outer face, and the compression projection of briquetting can be directly born against on the outer face of workpiece.
The application method of this fixture：Workpiece is placed in detent, and the card convex in detent is caught in work
In the locating slot of part both sides, rotate briquetting and it is compressed projection and push down the outer face of workpiece, tighten bolt cup of assaulting fortified position and be fixed on end
On plate, cutter is located at end plate side, and feeding lathe tool during main axis carries out turnery processing, after the completion of tool magazine tool changing, lathe tool is changed
Into bistrique, bistrique is fed in inner hole wall, completes grinding.
