Description
Technical field
The utility model relates to field of mechanical technique, particularly relates to a kind of fixture.
Technical background
Fixture is the critical piece of building-block machine, and existing centralizer is generally fixed, has centered positions and easily occur the shortcoming of deviation, also have and be not suitable for clamping central portion in addition, or need moving interval large, use shortcoming not too easily.
Summary of the invention
The purpose of this utility model is exactly for above-mentioned shortcoming, and a kind of centralized positioning automatically centering fixture is accurately provided.
The technical solution of the utility model is achieved in that a kind of automatically centering fixture, comprise base, on base, there is the projection protruding upward both sides, in projection, have in the Bing hole, hole that screw mandrel is installed screw mandrel is installed, screw mandrel has wire rod thread between two projections, it is characterized in that: described wire rod thread in two protruding centre positions on the screw mandrel of both sides being the screw thread of silk of reversing each other, one end of screw mandrel has the parts of moving, on the screw mandrel of both sides, protruding centre position, two cramping bodies are also installed, above described cramping body, be to clamp position, the retaining part of described cramping body is the opening of " V " shape, below cramping body, there is the Holding seat being arranged on screw mandrel, on Holding seat, there is the clamping hole of interspersed screw mandrel, it in clamping hole, is the screw thread that coordinates screw mandrel.
Say further, the described parts of moving are that screw mandrel one side is installed hydraulic motor, hydraulic motor connection wire rod.
The beneficial effects of the utility model are: such automatically centering fixture has centralized positioning advantage accurately; The described parts of moving are that screw mandrel one side is installed hydraulic motor, and hydraulic motor connection wire rod has that clamping is convenient, advantage rapidly.
Brief description of the drawings
Fig. 1 is the main TV structure schematic diagram of the utility model.
Wherein: 1, base 2, projection 3, screw mandrel 4, cramping body 5, clamp position 6, hold base 7, hydraulic motor.
specific embodiments:
Below in conjunction with accompanying drawing, the utility model is further described.
As shown in Figure 1, a kind of automatically centering fixture, comprise base 1, on base, there is the projection 2 protruding upward both sides, in projection, have in the Bing hole, hole that screw mandrel is installed screw mandrel 3 is installed, screw mandrel has wire rod thread between two projections, it is characterized in that: described wire rod thread in two protruding centre positions on the screw mandrel of both sides being the screw thread of silk of reversing each other, one end of screw mandrel has the parts of moving, on the screw mandrel of both sides, protruding centre position, two cramping bodies 4 are also installed, above described cramping body, be to clamp position 5, the retaining part of described cramping body is the opening of " V " shape, below cramping body, there is the Holding seat 6 being arranged on screw mandrel, on Holding seat, there is the clamping hole of interspersed screw mandrel, it in clamping hole, is the screw thread that coordinates screw mandrel.
In the time that parts rotation is moved in rotation, screw mandrel rotation, screw mandrel one side is moved left because screw thread drives cramping body, another section of screw mandrel is owing to being the screw thread of reversion, it drives cramping body above to move to the right, whether the always position at center, position in the middle of such two cramping bodies, need not often appraise and decide folder workpiece in the position at center, has advantage of the present utility model.
Say further, the described parts of moving are that screw mandrel one side is installed hydraulic motor 7, hydraulic motor connection wire rod.
Above embodiment is only part embodiment of the present invention, but aim of the present invention is not limited to this, and any those skilled in the art is in the field of the invention, and the variation of doing or modification and further expansion are all encompassed in the scope of the claims of the present invention.
Claims (2)
