Description

Quick-replacement positioning device for die

Technical Field

The utility model mainly relates to the mould production field especially relates to a mould quick replacement positioner

Background

The mould production often need process the product of different shapes, consequently often need change the mould, and the positioner of mould plays very important effect in stamping die, before stamping forming, at first need guarantee that the finished piece location is accurate, then when carrying out stamping work, positioner does not take place to interfere with last mould and relevant work subassembly. In the prior art, positioning is generally performed by a positioning frame, the positioning frame is a standard part and is arranged around a male die or a female die in a lower die of a stamping die during use, and a workpiece is positioned by a positioning part. For a workpiece with a large fluctuation profile and a stamping die with a small closing height, the positioning frame is easy to interfere with the upper die and the related working assembly, so that a space avoiding the positioning frame needs to be processed on the die, the design difficulty of the die is increased, the processing cost of the die is increased, and the development cost of the die is increased. According to the invention, the positioning device is additionally arranged on the workbench, so that the position of the die is quickly fixed, the low efficiency and the error of manual positioning are avoided, and the accuracy and the efficiency of processing can be improved.

SUMMERY OF THE UTILITY MODEL

To the above defect of prior art, the utility model provides a mould quick replacement positioner, which comprises a bracket 5, the symmetry is equipped with two clamping jaw devices on the support 5 and is used for the centre gripping location, clamping jaw device includes cylinder 1, connecting piece 2 and clamping jaw 4, connecting piece 2 is connected to the effect end of cylinder 1, connecting piece 2 is fixed at support 5 upper surface through round pin axle 3, clamping jaw 4 is connected to the other end that cylinder 1 was kept away from to connecting piece 2, two the upper surface center department at support 5 is fixed to 1 symmetry of cylinder, two the 4 symmetries of clamping jaw set up, and inwards centre gripping or unclamp simultaneously under the drive of two cylinders simultaneously, be equipped with fixed connection spare 7 that is used for fixing on the mould on support 5.

In use, the positioning device is fixed on one side of a die through the fixed connecting piece 7, the two cylinders 1 stretch out and draw back simultaneously to drive the two connecting pieces 7 to move, and under the action of the pin shaft 3, the power of the connecting pieces 7 is transmitted to the clamping jaws 4, so that the clamping jaws 4 simultaneously clamp inwards or simultaneously loosen to position a workpiece.

Preferably, two of the cylinders 1 are fixed at both ends of a connection fixing member 6, and the connection fixing member 6 is fixed at the center of the upper surface of the bracket 5.

In order to adjust the action angle of the air cylinder to change the action angle of the clamping jaw, preferably, two air cylinders 1 are fixed at two ends of the connecting and fixing piece 6 through screws.

Preferably, the bottom end of the support 5 is provided with two legs for fixing and supporting.

Preferably, the clamping surface of the clamping jaw 4 is provided with a cushion 401.

Preferably, the cushion 401 is made of rubber.

The utility model has the advantages that:

this positioner fixes the finished piece through clamping jaw device, and it fixes in one side of mould through the support simultaneously, does not influence the work of mould, and its centre gripping angle can be adjusted, and its clamping jaw has been changed, and the suitability is high, and the practicality is strong, has realized the quick replacement location of mould.
