Abstract
The utility model relates to a drill jig positioning mechanism which can especially be applied to a drill jig fixture with a comparatively large inner bore widely and the drill jig fixture adopts a positioning method of one plane-two pins. In the drill jig positioning mechanism, a footstock and a drill jig are assembled in a transition fit manner. A centring block fits a taper surface of a centring shaft with a cone head and the fit is fixed through a slotted countersunk head screw and a spring in a cover plate. A cushion block is pressed on a to-be-processed work piece. The tightness degree of the fit between the taper surface of the centring shaft and the centring block is adjusted by pulling a wrench to adjust a shouldered screw as well as a bolt on the centring shaft with the tapered head. An effective positioning fit between the positioning mechanism and the inner bore of the work piece is achieved timely according to the dimensional tolerance of the inner bore. Thus, the drill jig positioning mechanism has advantages of simple structure, convenient usage, high working efficiency and high positioning precision.
Description
Technical field
This is practical to relate to a kind of drill jig detent mechanism device, particularly a kind of being widely used on the drill jig that locate mode is a plane and two pits (the workpiece endoporus the is bigger) anchor clamps.
Background technology
In locate mode widely is on the drilling jig gripper of plane and two pits, general employing solid cylinder alignment pin and solid rhombus alignment pin location, and workpiece the dimensional tolerance in aperture of hole system processing normally change, the accuracy of manufacture tolerance of cylinder alignment pin is very important, workpiece the dimensional tolerance control in aperture of hole system processing bad, can influence the position error of subsequent handling with the location, hole, thereby the workpiece that influences subsequent handling processing just causes dimension overproof easily, reach the quality accident that workpiece is scrapped, so the cylinder alignment pin on the drilling jig gripper of plane and two pits is very crucial.At present, locate mode is on the drilling jig gripper of plane and two pits widely, and general employing solid cylinder alignment pin and solid rhombus alignment pin are located and guaranteed that it exists troublesome poeration, the drilling jig gripper heaviness, and work efficiency is low, the shortcoming of low precision.
Summary of the invention
The technical problems to be solved in the utility model provide a kind of simple in structure, easy to use, work efficiency is high, positioning accuracy is high and drill jig detent mechanism device.
The technical solution of the utility model is as follows: a kind of drill jig detent mechanism device comprises footstock, conehead centration axis, cover plate, cushion block, band shoulder nut, center bridge, flat key, spring, slotted countersunk flat head screw.Wherein, footstock and the assembling of drill jig interference fits, fixing the fixing of spring that reach of the slotted countersunk flat head screw of cone match on cover plate of center bridge and conehead centration axis, cushion block is pressed on the workpiece of being processed.
Thereby the degree of tightness that the utility model is pulled the screw rod on band shoulder nut and the conehead centration axis by spanner makes the conical surface adjusted on the conehead centration axis and the expansion and the contraction of center bridge, and timely dimensional tolerance size according to the aperture reaches effectively to locate with the endoporus of workpiece and cooperates; So it is simple in structure, easy to use, work efficiency is high, positioning accuracy is high.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Specific embodiments
Below in conjunction with accompanying drawing the specific embodiment of the present utility model is described in detail.
As shown in the figure, a kind of drill jig detent mechanism device comprises footstock 1, conehead centration axis 2, cover plate 3, cushion block 4, band shoulder nut 5, center bridge 6, flat key 7, spring 8, slotted countersunk flat head screw 9; Footstock 1 and the assembling of drill jig interference fits, center bridge 6 is pressed on the workpiece of being processed with slotted countersunk flat head screw 9 fixing, the cushion blocks 4 fixing and spring 8 of cone match on cover plate 3 of conehead centration axis 2.Thereby the degree of tightness of pulling the screw rod on band shoulder nut 5 and the conehead centration axis 2 by spanner makes the conical surface of adjusting on the conehead centration axis and the expansion and the contraction of center bridge, and timely dimensional tolerance size according to the aperture reaches effectively to locate with the endoporus of workpiece and cooperates
The above; it only is preferred embodiment of the present utility model; be not that the utility model is done any pro forma restriction; every foundation technical spirit of the present utility model all still belongs to the protection domain of technical solutions of the utility model to any simple modification, equivalent variations and modification that above embodiment did.
