Described the first screw rod lower end sliding fit refers to that the work nest longitudinal section is " protruding " shape in work nest and by the work nest vertical spacing, and the lower end of the first screw rod is provided with one and is convenient to the fixture block moved on spacing the first screw rod, and fixture block is positioned at work nest.
A rotation spanner is fixed in the upper end of the second screw rod.
Described briquetting front end lower surface is inclined to set.
The beneficial effects of the utility model are: after adopting above structure, the utility model fixture compared with prior art, have the following advantages: the utility model workbench is provided with at least two clamping devices that can simultaneously realize vertical and Level tune, be that clamping device on the utility model can be realized horizontal movement, horizontally rotates and move up and down, so, can adjust according to the size of workpiece to be processed, the scope of application is wider.
As preferably, described clamping device comprises briquetting, the first screw rod, the second screw rod, the briquetting middle part is provided with a word hole, and the first screw rod upper end is through the word hole in the middle part of briquetting and, through upper and lower two lock nuts locking, the first screw rod lower end sliding fit is in work nest and by the work nest vertical spacing; The upper end of the second screw rod and briquetting rear portion are spirally connected, and lower end and the worktable upper surface of the second screw rod offset.Simple in structure, be convenient to manufacture.
As preferably, described the first screw rod lower end sliding fit refers to that the work nest longitudinal section is " protruding " shape in work nest and by the work nest vertical spacing, and the lower end of the first screw rod is provided with one and is convenient to the fixture block moved on spacing the first screw rod.Simple in structure, be convenient to manufacture.
As improvement, a rotation spanner is fixed in the upper end of the second screw rod, is conveniently twisting the second screw rod 4.
As preferably, described briquetting front end lower surface is inclined to set, and plays a guide effect.

The specific embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
Shown in Fig. 1-Fig. 4, the utility model discloses a kind of fixture, it comprises workbench 1, on described workbench 1, table is provided with many horizontal operation grooves 1.1, it also comprises at least two clamping devices that can simultaneously realize vertical and Level tune, the lower end sliding fit of clamping device (be hereinafter mention the first screw rod 3 lower end sliding fits in work nest 1.1) in the work nest 1.1 of workbench 1.
Described clamping device comprises briquetting 2, the first screw rod 3, the second screw rod 4, briquetting 2 middle parts are provided with a word hole 2.1, the first screw rod 3 upper ends pass a word hole 2.1 at briquetting 2 middle parts and, through upper and lower two lock nuts, 3.1 lockings, the first screw rod 3 lower end sliding fits are in work nest 1.1 and by work nest 1.1 vertical spacings; The upper end of the second screw rod 4 and briquetting 2 rear portions are spirally connected, and the lower end of the second screw rod 4 and workbench 1 upper surface offset.A word hole 2.1 of briquetting 2 is passed in the upper end of the first screw rod 3, and with two lock nuts 3.1, briquetting is locked on the first screw rod 3.The first screw rod 3 shows that through a word hole 2.1 of briquetting 2 briquetting 2 can, with respect to the first screw rod 3 horizontal movements (length that motion amplitude is a word hole 2.1), unclamp two lock nuts 3.1 simultaneously and can realize moving up and down and horizontally rotating of briquetting 2.Described the second screw rod 4 and briquetting 2 rear portions be spirally connected refer to briquetting 2 rear portions be provided with the second screw rod 4 on the screwed hole 2.2 that matches of screw thread.
Described the first screw rod 3 lower end sliding fits refer to that work nest 1.1 longitudinal sections are " protruding " shape in work nest 1.1 and by work nest 1.1 vertical spacings, the lower end of the first screw rod 3 is provided with one and is convenient to the fixture block 3.2 moved on spacing the first screw rod 3, and fixture block 3.2 is positioned at work nest 1.1.Realized the vertical spacing of the first screw rod 3, simultaneously the first screw rod 3 can be in the interior slip of work nest 1.1, or skids off from work nest 1.1, then slides in another one work nest 1.1, with this, is applicable to the workpieces to be processed of different sizes.
A spanner 5 for rotation is fixed in the upper end of the second screw rod 4, is conveniently twisting the second screw rod 4.
Described briquetting 2 front end lower surfaces are inclined to set, and play a guide effect.
Operation principle of the present utility model is: shown in Fig. 4, workpiece 6 is put on workbench 1, according to the size of workpiece 6, select the riding position of clamping device, select which work nest 1.1, then pull the first screw rod 3 in the interior slip of work nest 1.1, choose an applicable position.Then regulate moving horizontally of briquetting 2, briquetting 2 is pressed in to workpiece 6 upper surfaces, rotate as required briquetting 2, adjust to an applicable position simultaneously; Turn two lock nuts 3.1, briquetting is pressed on to workpiece 6 upper surfaces, stir spanner 5 simultaneously, drive the second screw rod 4 rotations, make briquetting 2 rear portions upwarp, realize that briquetting 2 front ends compress.The combination of the first screw rod 3 and the second screw rod 4, realized effective clamping work pieces 6 of briquetting 2.The utility model can be adjusted according to the size of workpiece to be processed the clip position of clamping device, can use the workpiece of the large low height of multiple difference, and the scope of application is wider.
