Description

A kind of positioner

Technical field

The utility model relates to a kind of positioner, specifically, is that a kind of semiconductor that is used for is made the positioner of motion module with respect to stuck-module.

Background technology

In traditional positioner, generally adopt frock to position.This kind locate mode is that a frock at first is installed on motionless workpiece, the moving movement workpiece makes the motion workpiece combine with motionless workpiece on frock then, makes motion workpiece location by frock, and by alignment pin the motion workpiece is positioned on the motionless workpiece, again frock is dismantled at last.

The device that this kind utilizes frock to position, the position fixing process complexity, and need design frock in addition, increase cost; Simultaneously, it is too loaded down with trivial details to adorn the station-keeping mode that unloads again earlier, has reduced production efficiency.In addition, adopt the alignment pin location can cause further degree of regulation, and in maintenance engineering, need to dismantle the motion workpiece and motionless workpiece is reorientated, will produce the shortcoming of resetting process complexity, especially after resetting repeatedly, positioning accuracy also can reduce.

Number of patent application is that 200510024015.2 Chinese patent has also disclosed a rapid repeated positioning device.On the motion workpiece, positioning roller is set in the device of this patent, on motionless workpiece, is provided with a long and short two guide rail.When the motion workpiece is installed in the process of motionless workpiece, must guarantee that roller rolls on long guideway, must guarantee also that simultaneously the groove of positioning roller moves on short lead rail, after the pre-installation, carry out the location of x and y direction again by alignment pin.The defective of this kind device is that the groove of very possible roller can not accurately cooperate with short lead rail in pre-installation process, thereby causes pre-failure of installing.In addition, accurately locate by adopting alignment pin after the pre-installation, also possess in traditional positioner, adopt alignment pin cause repeating to install loaded down with trivial details, degradation shortcoming under the positioning accuracy.

The utility model content

The purpose of this utility model is to provide a kind of accurate rapid repeated positioning device, and it has high orientation precision, and the location is quick and resetting is simple.

For achieving the above object, positioner of the present utility model comprises motionless workpiece and motion workpiece, wherein, described motion workpiece one side is provided with at least one contact block, a groove and one one end are housed in the hook in the groove, and on motionless workpiece, be provided with lifting subassembly and a hook positioning component that cooperates with hook of cooperating with contact block, between motionless element and motor element contact, be provided with one pad at least.

Compared with prior art, positioner of the present utility model all is that the face by motionless workpiece and motion workpiece contacts and positions, have the function that promotes and locate simultaneously concurrently, need not special frock, and by the further degree of regulation of pad, regulate fast, resetting is simple, and then has improved operating efficiency.
