Description
Technical field
The utility model relates to a kind of fixture, what be specifically related to is a kind of for turning nut flange face fixture.
background technology
In fastener products, flange surface nut is applied greatly on a large scale because of its simple in structure, fastening area.The common structure of flange surface nut is: comprise outer-hexagonal body, in outer-hexagonal body, establish screwed hole, flange face is established in the lower surface of outer-hexagonal body.Because flange surface nut is generally to make by upsetting method processed, so its flange face need to carry out turning processing, object one is to make flange face keep smooth, the 2nd, and make flange face keep vertical with the screwed hole center of nut.And at present flange surface nut adds and normally positions with nut top end face carrying out flange face turning man-hour, so can not ensure that flange face and screwed hole center have very high vertical precision, and reality is, increasing client need to have the flange surface nut of higher vertical precision.And comparatively speaking, the fixture of prior art neither be very convenient to the clamping of nut workpiece, structure neither be very simple.
Summary of the invention
In view of the problem of current known technology existence, the technical problems to be solved in the utility model is to be to provide between a kind of nut flange face that makes turning processing and the screwed hole center of nut to have higher vertical precision, and clamping workpiece facilitates, turning nut flange face fixture simple in structure.
The utility model is implemented by the following technical programs:
Turning nut flange face fixture, it is characterized in that: comprise chuck, sliding sleeve, swollen nail and pull bar, chuck comprises anterior external screw thread and rear portion taper shank, the nut workpiece for the treatment of turning flange face is screwed on anterior external screw thread, rear portion taper shank is inserted in the inner hole of spindle of turning equipment, before and after having, chuck connects the axially extending bore at its center, the front end aperture of axially extending bore becomes the large female cone that forms, the cylindrical of described chuck is offered many axial groovings, axially grooving from front portion externally threaded front end face to the front end face of rear portion taper shank, described swollen nail is movable setting before and after doing in axially extending bore, the head of swollen nail has the outer cone matching with described female cone, outer cone and female cone are oppositely arranged, described sliding sleeve is fixed on the afterbody of swollen nail, slide over inner hole of spindle and do front and back slip setting, described pull bar is fixedly connected with sliding sleeve.
Adopt the turning nut flange face fixture of technique scheme, nut workpiece is screwed on the anterior external screw thread of chuck and positions with the screwed hole of nut, then carry out swelling realization fixing nut workpiece by double thread hole, carry out again the turning processing of flange face by the lathe tool of turning equipment, so, the flange face processing will have high vertical precision with screwed hole center, can be controlled in 0.05mm.Meanwhile, as can be seen from above, fixture is very convenient to the clamping of nut workpiece, and its structure is also very simple.
As preferably, described axial grooving is laid with four on the cylindrical circumference of chuck.
Brief description of the drawings
The utility model has following accompanying drawing:
Fig. 1 is structural representation of the present utility model,
Fig. 2 is the right view of Fig. 1.
Detailed description of the invention
Describe details and the operation principle of the utility model specific embodiment in detail below in conjunction with accompanying drawing:
As shown in the figure, turning nut flange face fixture of the present utility model, comprise chuck, sliding sleeve 2, swollen nail 5 and pull bar 1, chuck comprises anterior external screw thread 6 and rear portion Morse taper shank 4, the nut workpiece 7 for the treatment of turning flange face is screwed on anterior external screw thread 6, rear portion Morse taper shank 4 is inserted in the inner hole of spindle 3 of turning equipment, before and after having, chuck connects the axially extending bore at its center, the front end aperture of axially extending bore becomes the large female cone 8 that forms, the cylindrical of described chuck is offered four axial groovings 10, the axially front end face of grooving 10 from the front end face of anterior external screw thread 6 to rear portion Morse taper shank 4, described swollen nail 5 is movable setting before and after doing in axially extending bore, the head of swollen nail 5 has the outer cone 9 matching with described female cone 8, outer cone 9 is oppositely arranged with female cone 8, described sliding sleeve 2 is threaded connection mode and is fixed on the afterbody of swollen nail 5, sliding sleeve 2 slides and arranges before and after inner hole of spindle 3 is done, described pull bar 1 is fixedly connected with sliding sleeve 2 by the screw thread of drawhead.
Application process of the present utility model is: the nut workpiece 7 for the treatment of turning flange face is screwed on the anterior external screw thread 6 of chuck and is positioned with the screwed hole of nut 7, then by pulling back pull bar 1, pull bar 1 drives sliding sleeve 2, sliding sleeve 2 drives swollen nail 5 to move backward, so the outer cone 9 of swollen nail head pushes externally threaded female cone 8, external screw thread 6 elasticity are opened, the screwed hole of nut is carried out to swelling realization being fixedly clamped to nut workpiece 7, and then by the lathe tool of turning equipment, the flange face of nut workpiece is carried out to turning processing, because the processing of flange face is that screwed hole center taking nut is as positioning datum, so the flange face processing will have high vertical precision with screwed hole center, can be controlled in 0.05mm.
