A kind of double-screw bolt leveling formula fixture
Technical field
The present invention relates to clamp technology field, in particular to a kind of double-screw bolt leveling formula fixture.
Background technology
The applicable product parts of existing fixture is single, can not realize the assembling of Multiple Type product conllinear, to production, make troubles, the position of positioning hole of the close product workpiece of different model is different, need separated time to produce or change fixture to realize mixed production, consume more time and manpower, efficiency is low.
Summary of the invention
The object of the present invention is to provide a kind of double-screw bolt leveling formula fixture, the problem lowering efficiency causing to solve the single applicability of existing fixture.
For realizing the object of the invention, the technical scheme adopting is: a kind of double-screw bolt leveling formula fixture, comprise worktable panel, be positioned at the clamp bottom board on worktable panel, at least two locating pieces, locating piece is rounded and rotate and to be arranged on clamp bottom board, is fixedly installed alignment pin on locating piece; The lower surface of locating piece offers blind hole, is provided with spacer pin in blind hole, between the bottom surface, hole of spacer pin and blind hole, is provided with spring; The corresponding spacer pin position of clamp bottom board offers the spacing hole matching with spacer pin; Clamp bottom board is rectangle and its corner location offers top tapped through hole; The tapped through hole position, corresponding top of worktable panel is formed with the lower thread through hole identical with top tapped through hole; In top tapped through hole and lower thread through hole, be connected with double-screw bolt; On double-screw bolt, be connected with two nuts, a top that is positioned at clamp bottom board, another is between clamp bottom board and worktable panel.
Further, the end of described spacer pin is hemispherical.To enter more smoothly spacing hole as guiding.
Further, described spacer pin is at least two.
Further, described locating piece is rotated and is arranged on clamp bottom board by bearing.
The invention has the beneficial effects as follows, alignment pin can be realized rotation change location by locating piece on clamp bottom board, and the spacing hole inserting under the active force of spring by spacer pin on clamp bottom board is realized fixing, different product workpiece is used to different alignment pins, but also can realize the location that an alignment pin meets different workpieces by a plurality of spacer pins are set, solve the applicable single problem of fixture in the past, improved applicability and the efficiency of fixture.And the double-screw bolt by four jiaos of clamp bottom boards and nut the levelness of clamp bottom board is adjusted and regulate after can be locked by the nut of clamp bottom board top, realize the fine setting of different angles, improved the degree of accuracy, without workbench is carried out to Level tune, operation is more prone to simple.

The specific embodiment
Below by specific embodiment, also by reference to the accompanying drawings the present invention is described in further detail.
Fig. 1 to Fig. 3 shows double-screw bolt leveling formula fixture provided by the invention, comprise worktable panel 7, be positioned at clamp bottom board on worktable panel 71, at least two locating pieces 2, on locating piece 2, be fixedly installed alignment pin 3, locating piece 2 is rounded and rotate and to be arranged on clamp bottom board 1; The lower surface of locating piece 2 offers blind hole, is provided with spacer pin 4 in blind hole, between the bottom surface, hole of spacer pin 4 and blind hole, is provided with spring 5; Corresponding spacer pin 4 positions of clamp bottom board 1 offer the spacing hole 6 matching with spacer pin 4; Clamp bottom board 1 is rectangle and its corner location offers top tapped through hole; The tapped through hole position, corresponding top of worktable panel 7 is formed with the lower thread through hole identical with top tapped through hole; In top tapped through hole and lower thread through hole, be connected with double-screw bolt 8; On double-screw bolt 8, be connected with 9, one tops that are positioned at clamp bottom board 1 of two nuts, another is between clamp bottom board 1 and worktable panel 7.
The lower end of locating piece 2 is provided with construction section, and construction section is connected on clamp bottom board 1 by bearing, offers the groove that holds locating piece 2 on clamp bottom board 1.The end of spacer pin 4 is hemispherical, to insert better more smoothly spacing hole 6.Spacer pin 4 is at least two, can realize the location that an alignment pin 3 meets different workpieces.
The diameter of top tapped through hole and lower thread through hole is 8mm.Double-screw bolt 8 and nut 9 are made by stainless steel.During adjusting, the nut 9 between rotary work deck plate 7 and clamp bottom board 1 can be realized adjusting, finally by tightening the nut 9 of clamp bottom board 1 top, can fix.
The foregoing is only the preferred embodiments of the present invention, be not limited to the present invention, for a person skilled in the art, the present invention can have various modifications and variations.Within the spirit and principles in the present invention all, any modification of doing, be equal to replacement, improvement etc., within all should being included in protection scope of the present invention.
