Abstract

The invention relates to a fixture, in particular to an expending block floating fixture which comprises a fixture base body, a pressing arm, two clamping jaws and a sliding rod, wherein the pressing arm is taken as a force application device, and the middle part of the pressing arm is articulated on the fixture base body; the two clamping jaws are used for clamping a workpiece; the sliding rod is arranged on the fixture base body and can slide up and down along the fixture base body; the middle part of the sliding rod is provided with a bar-shaped hole; the two clamping jaws are crossed with each other and pass through the bar-shaped hole; the lower ends of the clamping jaws are articulated on the fixture base body, and the upper ends of the clamping jaws are used for fixing the workpiece; the lower part of the sliding rod is connected with a vertical bolt which sequentially passes through the fixture base body and a spring; the spring is pressed onto the base body by a nut capable of sliding on the vertical bolt; a driven end of the pressing arm leans against and is connected with the lower part of the nut; and a driving end of the pressing arm is taken as a force application end. The expending block floating fixture has the beneficial effects that the clamping device is ingenious and reasonable in arrangement as well as free in stretching, contracting and clamping.

Description

A kind of expansion block stationary fixture that floats
Technical field:
The present invention relates to a kind of stationary fixture, especially a kind of expansion block stationary fixture that floats.
Background technology:
Anchor clamps and grip device are widely known by the people, and are widely used for manufacturing, and particularly, anchor clamps have various reference surfaces and point, and parts or instrument can accurately be located.In many process, general application anchor clamps, so that these parts can keep correct position relationship in for example punching press, riveted joint, welding, the process of pasting or solidifying, anchor clamps are considered to requisite parts in the processing industry, and be the vitals of calculating processing cost, also be the vitals that requires in process of production logistics to consider, most position fixing process all utilize anchor clamps to realize.
Anchor clamps need to arrange or choose according to profile and the size of workpiece, and the anchor clamps that utilize expansion block and spring cooperate to clamp need reach, and transmission performance is stable, conveniently regulate and be easy to the characteristics such as frock.
?
Summary of the invention:
The technical problem to be solved in the present invention is: provide a kind of transmission performance stable, conveniently regulate and be easy to the unsteady stationary fixture of expansion block of frock.
In order to solve the above problems, the invention provides the unsteady stationary fixture of a kind of expansion block and comprise clip base, be hinged on pressure arm on the clip base as force application apparatus and middle part, two jaws of clamping work pieces, on clip base and along its slide bar that slides up and down, described slide bar middle part is provided with bar hole, described jaw intersection is also passed bar hole, the lower end of jaw is hinged on clip base, the upper end fixation workpiece, the bottom of described slide bar is connected with vertical bolt, this vertical screw bolt passes clip base, spring and by can spring being expressed on the matrix at the nut that vertical bolt slides, the driven end of pressure arm is connected to the nut below, the drive end of pressure arm is as the force side, the upper surface of described slide bar is provided with a vertical hole of running through with bar hole, be provided with the rocker piece of regulating by bolt in this vertical hole, this rocker piece is positioned at the cross part top of two jaws.
The use principle of expansion block floating clamp: because the spring between nut and the clip base drives vertical bolt and slide bar, so that be connected that with slide bar the rocker piece that connects compresses jaw downwards, so that jaw is in the state of clamping.Come clamping work pieces with these anchor clamps, need by the pressure arm Compress Spring, so that move on the vertical bolt band moving slide-bar, unclamp jaw thereby move on the rocker piece, unclamp workpiece.
Use the unsteady stationary fixture of expansion block of technical solution of the present invention that following benefit is arranged: 1, because the bottom of slide bar is connected with vertical bolt, this vertical screw bolt passes clip base and spring also are expressed to spring on the matrix by nut, and the driven end of pressure arm is connected to the nut below, can upwards press nut by pressure arm, so that spring-compressed, drive vertical bolt and slide bar and move up, rocker piece just can unclamp workpiece, not to the pressure arm application of force, spring action, rocker piece compresses jaw; 2, described jaw is that two jaws that can mutually slide form, and when promoting slide-bar, can unclamp simultaneously and clamp jaw.
The right arm of described jaw is U-shaped forked, and left arm is dumbbell shaped, and described left arm snaps fit onto in the right arm, and jaw can play one from spacing effect, and so that jaw does not produce interference.
 
Description of drawings:
Fig. 1 is the structural representation of the unsteady stationary fixture of present embodiment expansion block;
Fig. 2 is the structural representation of Fig. 1 jaw.
The specific embodiment:
Below in conjunction with drawings and Examples technical solution of the present invention is further specified:
As depicted in figs. 1 and 2: the unsteady stationary fixture of a kind of expansion block comprises clip base 1, be hinged on pressure arm 3 on the clip base 1 as force application apparatus and middle part, two jaws 7 of clamping work pieces, on clip base 1 and along its slide bar that slides up and down 2, slide bar 2 middle parts are provided with bar hole, jaw 7 intersections are also passed bar hole, the lower end of jaw 7 is hinged on clip base 1, the upper end fixation workpiece, the bottom of slide bar 2 is connected with vertical bolt 4, this vertical bolt 4 passes clip base 1 successively, spring 6 and the nut 5 by sliding at vertical bolt 4, nut 5 is expressed to spring 6 on the matrix, the driven end of pressure arm 3 is connected to nut 5 belows, the drive end of pressure arm 3 is as the force side, the upper surface of slide bar 2 is provided with a vertical hole of running through with bar hole, be provided with the rocker piece 8 of regulating by bolt in this vertical hole, this rocker piece 8 is positioned at the cross part top of two jaws.
The use principle of expansion block floating clamp: because the spring 6 between nut 5 and the clip base 1 drives vertical bolt 4 and slide bar 2, so that the rocker piece 8 that slide bar 2 connects compresses jaw 7 downwards, so that jaw 7 is in the state of clamping.Come clamping work pieces with these anchor clamps, by pressure arm 3 Compress Springs 6, so that move on the vertical bolt 4 band moving slide-bars 2, unclamp jaw 7 and unclamp workpiece thereby move on the rocker piece 8.
The right arm of jaw 7 is U-shaped forked, and left arm is dumbbell shaped, and left arm snaps fit onto in the right arm, and jaw 7 can play one from spacing effect, and so that jaw 7 discord slide bars 2 produce interference.
Above-described only is preferred embodiment of the present invention; should be understood that; for a person skilled in the art; under the prerequisite that does not break away from structure of the present invention; can also make some distortion and improvement; these also should be considered as protection scope of the present invention, and these can not affect effect of the invention process and practical applicability.
