Abstract

The utility model relates to a clamp positioning quick-switch mechanism. The clamp positioning quick-switch mechanism comprises a base, a bracket, a rotating shaft and at least one positioning pin, the bracket is provided with two supporting arms which are spaced and extend upwards, the rotating shaft is connected with the bracket and the base so that the bracket can rotate on the base by making the rotating shaft as the center, the bottom of the bracket is connected with the at least one positioning pin, the bracket is provided with a plurality of pin holes, and the positioning pins are inserted in the pin holes of the bracket. The rotating shaft is provided with a spring; the spring applies downward force to the bracket through the rotating shaft so that the bracket can be pulled upwards and rotate by 180 degrees, and then the positioning pins are inserted into the pin holes of the bracket; the rotating shaft is located at the position, deviating from the centers of the two supporting arms, between the two supporting arms of the bracket.

Description

Fixture location quick switching mechanism

Technical field

The utility model relates to fixture location quick switching mechanism.

Background technology

Present stage, the automobile industry vehicle is of a great variety, in the process of exploitation, finds that there is a lot of shape of product structures similar, and for similar part, the transformation by assembling jig can reach equipment and share, cost-saving, the advantage of saving the development time.Although yet product is similar, but be not just the same, to take into account a plurality of product structures when transformation, meet again productive temp, need the operation of convenient operation work simultaneously, this is problem demanding prompt solution in industry always.

The utility model content

The utility model relates to fixture location quick switching mechanism

For realizing the fixture location quick switching mechanism of described purpose, it comprises pedestal, carriage, rotating shaft and at least one alignment pin, carriage has isolated upwardly extending two trailing arms, rotating shaft connects carriage and pedestal, so that carriage can be rotated centered by rotating shaft on pedestal, the bottom of carriage is connected with described at least one alignment pin, a plurality of pin-and-holes are arranged on carriage, alignment pin is inserted in the pin-and-hole of carriage, spring is housed in rotating shaft, spring is applied with downward power by rotating shaft to carriage, so that carriage can be pulled upwardly and turn over 180 degree, again alignment pin is inserted in the pin-and-hole of carriage, the position at the center of departing from two trailing arms of rotating shaft between two trailing arms of carriage.

Described fixture location quick switching mechanism, wherein, the bottom of carriage is connected with two described alignment pins, and two alignment pins are symmetrical centered by rotating shaft, and on pedestal, corresponding two described alignment pins have two described pin-and-holes.

Then be automatically positioned on pedestal because carriage can be pulled up rear rotation 180 degree, so the operation of convenient operation work, reach the purpose of quick switching.

The accompanying drawing explanation

Fig. 1 is the main pseudosection of fixture location quick switching mechanism.

Fig. 2 is the left view of fixture location quick switching mechanism.

Fig. 3 is the top view of fixture location quick switching mechanism.

Fig. 4 is that the axle of fixture location quick switching mechanism is surveyed view.

The specific embodiment

As shown in Figures 1 to 4, fixture location quick switching mechanism comprises pedestal 1, carriage 2, rotating shaft 3 and two alignment pins 7.Carriage 2 has isolated two trailing

arms

21, 22, rotating shaft 3 connects carriage 2 and pedestal 1, so that carriage 2 can be rotated centered by rotating shaft 3 on pedestal 1, the bottom of carriage 2 connects two alignment pins 7, two pin-and-holes (as shown in the figure) are arranged on carriage 2, alignment pin 7 is inserted in the pin-and-hole of carriage 2, spring 5 is housed in rotating shaft 3, spring 5 is applied with downward power by rotating shaft 3 to carriage 2, carriage 2 can be pulled upwardly and be turned over 180 degree and alignment pin 7 is inserted in the pin-and-hole of carriage 2 again, rotating shaft 3 is positioned at two trailing arms 21 of carriage 2, depart from two trailing arms 21 between 22, the position at 22 center.

Previous embodiment is utilized the eccentric throw principle, uses rotating shaft 3 to add the structure of alignment pin 7, and carriage 2 is rotated to 180 °, makes in two carriage 2(figure and only shows a carriage) spacing just in time is in the width range of two products.

Previous embodiment is when work, spring 5 is housed in rotating shaft 3, make carriage 2 that a downward pulling force be arranged, the fixing alignment pin 7 in two ends stretches in the pin-and-hole of pedestal 1, during the product switching, carriage 2 is up drawn, make alignment pin 7 deviate from pedestal 1, then carriage is turned over to 180 °, then insert in pin-and-hole, complete switching.Therefore be convenient to manual operations.

The top of two trailing

arms

21,22 is provided with nylon cushion block 6, is mainly used in the fixture location.

In other embodiments, alignment pin 7 can be at least one.
