Abstract
The utility model provides a measure anchor clamps of bone screw tooth form on projecting apparatus, includes chassis fixing base, chassis roating seat and the rotatory round pin of linking, the chassis roating seat is fixed on the fixing base of chassis through the activity of rotatory interlinkage round pin, the both ends of chassis roating seat set up the stand respectively, wherein set up the sharp fixed column of nail on the stand of one end, set up head of a nail fixed column on the stand of the other end, and follow closely sharp fixed column and head of a nail fixed column sets up in opposite directions. Insert the helix angle angular gauge block in the gap that turns over between chassis fixing base and chassis roating seat, and the angle of helix angle angular gauge block is the same with bone screw's helix angle, opens the light source and shines the work piece to avoid bone screw and go up because of the partial tooth form that helix angle sheltered from, thereby can carry out effectual measurement to the work piece in process of production, with the qualification rate of guaranteeing the work piece product.
Description
Technical field
This utility model relates to the technical field of apparatus detection, a kind of fixture measuring bone screw tooth form on projector.
Background technology
At present in machining process, need screw tooth form is measured, error can not be controlled during measuring, often cause tool selection mistake, so that product is defective, ultimately results in screw operation and can not effectively be attached fixing.Existing detection means relative efficiency is relatively low.
Utility model content
The technical problems to be solved in the utility model is to provide a kind of fixture measuring bone screw tooth form on projector.
This utility model is adopted the technical scheme that by solving technical problem present in known technology:
The fixture measuring bone screw tooth form on projector of the present utility model, including base plate fixing holder, chassis rotating seat and rotary link pin, chassis rotating seat is movably fixed on base plate fixing holder by rotary link pin, arranges lead angle angle block gauge between the gap that chassis rotating seat and base plate fixing holder mutually turn over；The two ends of chassis rotating seat are respectively provided with column, wherein arrange nail tip on the column of one end and fix post, the column of the other end arrange the head of a nail and fixes post, and nail tip fixes post and the head of a nail is fixed post and is oppositely arranged.
This utility model can also use techniques below measure:
Nail tip fixes post and the coaxial setting of post fixed by the head of a nail.
Nail tip is fixed the tail end of post and is arranged stop nut, and nail tip is fixed post and through the through hole on its respective side column and is slidably connected with column, and fixes in nail tip and arrange thrust spring between stigma end and column.
The head of a nail is fixed post and through the through hole on its respective side column and is fixed with column by locking nail.
The angle of lead angle angle block gauge is the lead angle of bone screw.
Lead angle angle block gauge is two, is separately positioned in the gap, both sides that chassis rotating seat turns over.
This utility model has the advantage that with good effect:
In the fixture measuring bone screw tooth form on projector of the present utility model, base plate fixing holder and the chassis rotating seat of flexible connection are set, the gap turned between base plate fixing holder and chassis rotating seat is inserted lead angle angle block gauge, and the angle of lead angle angle block gauge is identical with the lead angle of bone screw, open light source workpiece is irradiated, thus avoid the part tooth form sheltered from bone screw because of lead angle, thus workpiece effectively can be measured in process of production, to ensure the qualification rate of workpiece product.Not only screw tooth form angle can be measured but also the defect on workpiece can have been detected by this utility model, and facilitate processing and inspection, improve efficiency in process of production, reduce man-hour.
Accompanying drawing explanation
Fig. 1 is the structural representation of the fixture measuring bone screw tooth form on projector of the present utility model；
Fig. 2 is the fixture of measurement bone screw tooth form schematic diagram in the measurements on projector of the present utility model.
Detailed description of the invention
Below by way of the drawings and specific embodiments, the technical solution of the utility model is described in detail.
As depicted in figs. 1 and 2, the fixture measuring bone screw tooth form on projector of the present utility model, including base plate fixing holder 1, chassis rotating seat 2 and rotary link pin 3, chassis rotating seat is movably fixed on base plate fixing holder by rotary link pin, arranges lead angle angle block gauge 9 between the gap that chassis rotating seat and base plate fixing holder mutually turn over；The two ends of chassis rotating seat are respectively provided with column 4, nail tip is wherein set on the column of one end and fixes post 6, arranging the head of a nail on the column of the other end and fix post 7, nail tip fixes post and the head of a nail is fixed post and is oppositely arranged, and fixes post and the head of a nail is fixed and fixed bone screw 10 between post in nail tip.
Nail tip fixes post and the coaxial setting of post fixed by the head of a nail, in order to workpiece is effectively projected by projection light source.
Nail tip is fixed the tail end of post and is arranged stop nut, nail tip is fixed post and through the through hole on its respective side column and is slidably connected with column, and fix in nail tip thrust spring 5 is set between stigma end and column, nail tip fixes post can ensure the chucking power to bone screw by thrust spring, can also meet the size adjusting needs of different bone screw simultaneously.
The head of a nail is fixed post and through the through hole on its respective side column and is fixed with column by locking nail 8, can adjust the link position that the head of a nail is fixed between post and column as required, to adapt to the measurement demand of different size screw.
The angle of lead angle angle block gauge is the lead angle of bone screw, thus evades the obstruction that profile of tooth is projected by lead angle in projection.
Lead angle angle block gauge is two, is separately positioned in the gap, both sides that chassis rotating seat turns over.
The above, it it is only preferred embodiment of the present utility model, not this utility model is made any pro forma restriction, although this utility model is open as above with preferred embodiment, but, it is not limited to this utility model, any those skilled in the art, in the range of without departing from technical solutions of the utility model, certainly the technology contents of announcement can be utilized to make a little change or modification, become the Equivalent embodiments of equivalent variations, in every case it is the content without departing from technical solutions of the utility model, any simple modification above example made according to technical spirit of the present utility model, equivalent variations and modification, belong in the range of technical solutions of the utility model.
