Abstract

The invention discloses a multi-workpiece positioning fixture, and belongs to the technical field of fixtures. The multi-workpiece positioning fixture comprises a workbench panel, a fixture bottom plate positioning on the workbench panel, and at least two positioning blocks, wherein the positioning blocks are circular and are rotationally arranged on the fixture bottom plate; positioning pins are fixedly arranged on the positioning blocks; the lower surfaces of the positioning blocks are provided with blind holes; limiting pins are arranged in the blind holes; springs are arranged between the limiting pins and the bottom surfaces of the blind holes; the fixture bottom plate is provided with limiting holes matched with the limiting pins corresponding to the positions of the limiting pins; the fixture bottom plate is provided with two transversely-formed sliding chutes; the sliding chutes penetrate through the upper and lower surfaces of the fixture bottom plate; the upper surface of the workbench panel is provided with two longitudinally-formed T-shaped grooves. The positions of the positioning pins are changed rotationally through the positioning blocks, and the limiting pins are inserted into the limiting holes in the fixture bottom plate for fixing under the acting force of the springs. Different positioning pins are used for different product workpieces, so that the adaptability of the fixture is enhanced, and the efficiency is increased.

Description

A kind of multi-work piece positioning fixture
Technical field
The present invention relates to clamp art, in particular to a kind of multi-work piece positioning fixture.
Background technology
The product parts that existing fixture is suitable for is single, the assembling of Multiple Type product conllinear can not be realized, make troubles to production, 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 multi-work piece positioning fixture, the problem lowered efficiency caused with the single applicability solving existing fixture.
For realizing the object of the invention, the technical scheme adopted is: a kind of multi-work piece positioning fixture, comprise worktable panel, the clamp bottom board be positioned on worktable panel, at least two locating pieces, locating piece rounded and rotate be arranged on clamp bottom board, locating piece is fixedly installed alignment pin; The lower surface of locating piece offers blind hole, is provided with spacer pin in blind hole, between spacer pin and the bottom surface, hole of blind hole, be provided with spring; The corresponding spacer pin position of clamp bottom board offers the spacing hole matched with spacer pin; Clamp bottom board offers the chute of two horizontally sets, and the through upper and lower surface to clamp bottom board of chute, the upper surface of worktable panel offers two T-slots longitudinally arranged.
Further, the end of described spacer pin is hemispherical.To enter spacing hole more smoothly as guiding.
Further, described spacer pin is at least two.
Further, described locating piece is rotated by bearing and is arranged on clamp bottom board.
The invention has the beneficial effects as follows, alignment pin can realize rotating change location by locating piece on clamp bottom board, and realize fixing by the spacing hole that spacer pin inserts on clamp bottom board under the force of a spring, different alignment pins is used to different product workpiece, but also the location of different workpieces is met by arranging multiple spacer pin to realize an alignment pin, solve fixture in the past and be suitable for single problem, improve applicability and the efficiency of fixture.And the combination of horizontal concrete chute and longitudinal T-slot, there is larger adjustable range, clamp bottom board and working panel are surperficial Full connected substantially, press-fiting in process, the stability of clamp bottom board is high compared to the modification stability of clamp body in prior art, not easily occur, offset or slip etc., being conducive to guarantee press-fits precision, and structure is simple and practical.
