Abstract
The utility model relates to a cylindrical work piece presss from both sides tight positioner, including the base, pressing from both sides tight arm and support frame, the support frame is fixed on the base, presss from both sides tight arm and is L shape, and the one end of pressing from both sides tight arm is connected with the support frame rotation, and the other end that presss from both sides tight arm is relative with the base, and open one side that the base is relative with pressing from both sides tight arm has first recess, and the one end that the tight arm of clamp is relative with the base is left there is the second recess, and first recess and second recess are arc, and first recess forms the round hole with the cooperation of second recess, is connected with reset spring between tight arm of clamp and the support frame, during the clamping work piece, pulling open the tight arm of clamp and making it keep away from the base, put into the first recess on the base with the work piece, loosen and press from both sides tight arm, press from both sides tight arm and rebound under reset spring's effect, the second recess is tight with the work piece clamp with first recess, simple structure, and the operation of being convenient for, it is with low costs.
Description
Technical field
The utility model relates to work piece holder technical field, especially a kind of cylindrical work clamping and positioning device.
Background technology
Jig is a kind of device in order to clamping workpiece (with guiding cutter) on lathe, and its effect is by Workpiece fixing, to make workpiece acquisition relative to the tram of lathe and cutter, and workpiece is reliably clamped.Employing fixture is installed, and can determine the mutual alignment between workpiece and lathe, cutter exactly, the positional precision of workpiece is ensured by fixture, and not by the impact of workman's technical merit, its machining accuracy is high and stable.Use fixture clamping workpiece, workpiece just can be made promptly to locate and clamp without the need to centering, significantly reduce unproductive time; Improve the rigidity of workpiece with fixture clamping workpiece, therefore can strengthen cutting data; Can use more than one piece, multi-station clamp clamping workpiece, and adopt efficient clamp system, these factors are all conducive to raising labour productivity.In addition, after adopting fixture, constant product quality, percent defective declines, and can arrange the workman that industrial grade is lower, significantly reduce production cost.Use special fixture can change the purposes of former lathe and expand the scope of application of lathe, realize one-machine-multi-function.Such as, after boring template fixture installed by lathe or arm drilling machine, just can carry out boring processing to box body hole system; Also lathe can be changed into broaching machine by special fixture to use, to give full play to the effect of universal machine tools.
Utility model content
The technical problems to be solved in the utility model is: in order to solve existing jig complex structure, problem that cost is higher, provide the cylindrical work clamping and positioning device that a kind of structure is simple, cost is low.
The utility model solves the technical scheme that its technical problem adopts: a kind of cylindrical work clamping and positioning device, comprise base, clamp arm and bracing frame, support frame as described above is fixed on base, described clamp arm is L shape, one end and the bracing frame of described clamp arm are rotationally connected, the other end of described clamp arm is relative with base, side relative with clamp arm on described base has the first groove, one end relative with base on described clamp arm has the second groove, described first groove and the second groove are circular arc, described first groove and the second groove fit form circular hole, back-moving spring is connected with between described clamp arm and bracing frame.
During clamping workpiece, pull open clamp arm and make it away from base, workpiece is put into the first groove on base, unclamp clamp arm, clamp arm rebounds under the effect of back-moving spring, and the second groove and the first groove are by Workpiece clamping.
Further, in order to increase the contact area of the second groove and workpiece, make clamping more reliable, described clamp arm is provided with the fixture block widened near one end of base, described second groove is opened on described fixture block.
Further, in order to by Workpiece clamping, the face that described base is relative with fixture block is inclined-plane, and the lower surface of described inclined-plane and fixture block fits tightly.
The beneficial effects of the utility model are, during clamping workpiece, pull open clamp arm and make it away from base, workpiece is put into the first groove on base, unclamp clamp arm, clamp arm rebounds under the effect of back-moving spring, and the second groove and the first groove are by Workpiece clamping, structure is simple, and convenient operation, cost is low.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated.
