Very harmful.
Summary of the invention
For the defect overcoming above-mentioned prior art to exist, it is an object of the invention to provide a kind of line cutting locating clip
Tool, this positioning fixture structure is reasonable in design, makes workpiece directly to position in fixture, carries out line cutting, saves multiple tracks auxiliary
Operation, improves part production efficiency.
The present invention is to be achieved through the following technical solutions:
A kind of line cutting positioning fixture, including L-type chuck body, L-type chuck body is to be connected with workbench
Fixed edge, this fixed edge arranges bracer, and forms the locating piece of the first spherical location, set inside a bracer
There is auxiliary jacking device, be additionally provided with housing screw at the top of a bracer；It is provided with location inside the another side of L-type chuck body
Body, positioning body upper end is provided with two spacers, and lower end is provided with the second spherical location.
Described auxiliary jacking device is made up of top-fastening rod, spring and blanking cover；Spring one end is connected with bottom top-fastening rod, another
End is connected with blanking cover.
Described spacer is in " V " type structure, and spacer is made up of antifriction alloy.
It is additionally provided with the head alive of the compression for preventing from weighing wounded workpiece in housing screw end, compresses head of living by nylon material system
Become.
Prop up bracer, locating piece and positioning body to be connected with L-type chuck body by screw respectively.
Compared with prior art, the present invention has a following useful technique effect:
Line cutting positioning fixture disclosed by the invention, including the chuck body being of an L-shaped structure, chuck body be
The fixed edge being connected with workbench, the inner side of fixed edge forms the locating piece with the first spherical anchor point, and is used for installing
A bracer of auxiliary jacking device and housing screw, forms two spacers of band and the inside the another side of chuck body
The positioning body of two spherical anchor points, positions for workpiece.When using this fixture clamping workpiece, workpiece is fixed with interfix benchmark
Position, makes the cantilevered out chuck body in linear cutter position；During clamping workpiece, the spring force produced by fixture auxiliary jacking device makes work
Part is fitted voluntarily with spacer and spherical anchor point, then compresses with housing screw, can be with extremely convenient ground clamping workpiece, and surely
Fixed reliable, it is suitable for similar structures workpiece alignment cutting processing use, the workpiece being especially suitable for the cutting of profile overall wire is used.Workpiece is straight simultaneously
It is connected in fixture location, linear cutter, eliminates cast location alloy, remove the multiple tracks aided processes such as location alloy, simplify
Technique, improves part production efficiency.
Further, auxiliary jacking device is made up of top-fastening rod, spring and blanking cover；Two spacers on positioning body are V
Type antifriction alloy spacer, when clamping workpiece, unclamps top-fastening rod and makes it rely on spring force top tight workpiece, it is possible to fully ensure that workpiece
Two V-type antifriction alloy spacers of cross section positioning datum and this fit tightly, by tightening housing screw so that it is contact workpiece table
Face, it is achieved the clamping to workpiece.
Further, in order to prevent workpiece damage, being additionally provided with compression head alive in housing screw end, this compression lives head by Buddhist nun
Dragon material is made.
