Abstract
The utility model discloses a hydraulic self-centering tension pin mechanism which comprises a base and an end cover. The end cover is positioned above the base, a circular hole is arranged in the center of the base, a piston, an ejector block, sliders and positioning columns are mounted in the circular hole, the sliders are respectively connected with the ejector block and the positioning columns, and the piston is connected with the ejector block by a bolt and is used for driving the ejector block to move vertically, so that the positioning columns are driven to be enlarged or shrunk radially. The hydraulic self-centering tension pin mechanism has the advantages of accuracy in hydraulic centering, capabilities of quickly clamping a workpiece and providing continuous clamping force, easiness in machining and manufacturing, simplicity and convenience in assembly and maintenance, low work friction force and high work efficiency.
Description
Technical field
The utility model relates to the Machining Technology field, particularly relates to a kind ofly can accurately locating, clamping fast, and the hydraulic self-centering that the continues clamping force pin mechanism that rises is provided.
Background technology
Generally be smooth circular alignment pin as location and clamping element in the mechanical industry at home at present, prismatic pin, the rise clamp mechanism of guide and driving of elasticity; General all is the size of being determined alignment pin by the size of product endoporus, its weak point is that this type of location was easy to generate the location, requirement on machining accuracy is higher, the requirement strictness that is installed, inefficiency, accurate positioning is poor, can not process the product of minor diameter, can not provide lasting clamping force, the effect of influence processing.
The utility model content
(1) technical problem that will solve
Problem to be solved in the utility model provides a kind of hydraulic self-centering pin mechanism that rises, to overcome defective of the prior art.
(2) technical scheme
For achieving the above object, the utility model provides a kind of hydraulic self-centering pin mechanism that rises, and comprises base and end cap, and described end cap is positioned at described base top;
Described base center is provided with circular hole, piston, jacking block, slide block and reference column are installed in the described circular hole, described slide block links to each other with reference column with described jacking block respectively, described piston links to each other by bolt with jacking block, described piston be used for to drive moving up and down of jacking block, thereby it is big or dwindle to drive the radially change of reference column;
Described jacking block is the double inclined plane structure, and surface slope is 60 degree;
Described reference column is the double inclined plane structure, and surface slope is 60 degree;
Described piston jacket has the O RunddichtringO.
Further, described reference column is provided with elongated slot, is provided with in the elongated slot be used to making the directed holding screw that slides of reference column.
Further, described reference column is a plurality of.
Further, the double inclined plane on the described jacking block matches with the double inclined plane of described reference column, and the double inclined plane of described reference column is free to slide at the double inclined plane of jacking block.
(3) beneficial effect
Compared with prior art, the technical solution of the utility model has the following advantages: centering accurately can realize the quick-clamping workpiece, and lasting chucking power can be provided, and is easy to processing and manufacturing, and the assembling maintenance is easy, and the frictional force of work is little, high efficiency.
Description of drawings

The described piston 6 outer O RunddichtringOs 9 that are with.
Described reference column 5 is provided with elongated slot, is provided with in the elongated slot be used to making the directed holding screw 3 that slides of reference column.
Described reference column 5 is a plurality of.
Double inclined plane on the described jacking block 2 matches with the double inclined plane of described reference column 5, and the double inclined plane of described reference column 5 is free to slide at the double inclined plane of jacking block 2.
The hydraulic self-centering pin mechanism that rises also comprises oil circuit mouth 10.
As shown in Figure 2, hydraulic pressure has two oil circuit mouths of one-in-and-one-out; Promote piston during oil-feed and move up the reference column spreading; Oppositely oil-feed then promotes piston and moves down the reference column contraction.
The utility model hydraulic self-centering rises by pin mechanism centering accurately, can realize the quick-clamping workpiece, and lasting chucking power can be provided, and be easy to processing and manufacturing, the assembling maintenance is easy, and the frictional force of work is little, high efficiency.
The above only is preferred embodiment of the present utility model; should be understood that; for those skilled in the art; under the prerequisite that does not break away from the utility model know-why; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
