A kind of alignment pin rotary type pressing machine
Technical field
The present invention relates to press-loading device field, in particular to a kind of alignment pin rotary type pressing machine.
Background technology
The product parts that the fixture of existing pressing machine 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 alignment pin rotary type pressing machine, the problem lowered efficiency caused with the single applicability solving existing pressing machine.
For realizing the object of the invention, the technical scheme adopted is: a kind of alignment pin rotary type pressing machine, comprise frame and be positioned at the positioning fixture in frame, positioning fixture comprises clamp bottom board and at least two locating pieces, locating piece is fixedly installed alignment pin, and locating piece is rounded and rotation is arranged on clamp bottom board; 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.
Further, the end of described spacer pin is hemispherical.
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 pressing machine in the past and be suitable for single problem, improve applicability and the efficiency of pressing machine.
