Abstract

The utility model relates to a positioning device for a hydraulic press mold changing car. The utility model is characterized in that a fixed plate is arranged on the car body of the mold changing car; the upper end and the lower end of the fixed plate are respectively and fixedly provided with an upper hinge seat and a fixed block with a perpendicular pin hole which are opposite vertically; a positioning pin is inserted in the pin hole of the fixed block; the upper hinge seat and the positioning pin are respectively hinged on an upper connecting plate and a lower connecting plate; a side hinge seat is fixed to one side edge between the upper hinge seat and the fixed block on the fixed plate; the side hinge seat is hinged on an air cylinder with a piston rod which is provided with a protruding head of which the end head is fixedly provided with a hinge frame; the upper connecting plate hinged on the upper hinge seat is crossed in line with the lower connecting plate hinged on the positioning pin, and the two connecting plates are all hinged on the hinge frame fixed to the end head of the piston rod; a positioning groove corresponding to the fixed block is arranged beside the travel track of the mold changing car. The utility model has the advantages of realized accurate positioning of the mold changing car, compact structure and prolonged service life of the air cylinder which can be in a better stress state.

Description

The positioner of hydraulic press die change dolly

Technical field

The utility model belongs to the parts of forcing press auxiliary device, particularly relates to a kind of positioner of hydraulic press die change dolly.

Background technology

Die change dolly at the present mold changing systems that hydraulic press was equipped with, when mold exchange more, in order to make the die change dolly be parked in preposition, usually adopt the dead block that installing is fixed on the track of carriage walking to position by the stop position of travel switch sender to dolly, the locate mode of this structure, because the wearing and tearing that the long-term use of block causes, and the reaction force of dolly when stopping to cause displacement, can make the location inaccuracy of dolly, this is for the die change dolly that need be used with other device, will make a big impact, for example at the push-pull chain that adopts one section both sides band roller during as the actuated element of template transmission device, because push-pull chain needs to walk in chain walking groove, thereby will be respectively on the template conveying device, the walking groove of push-pull chain is installed on the table top of connection platform in the middle of on the table top of die change dolly and the dolly side, thereby need the accurate location of die change dolly, to realize the accurate butt joint of each push-pull chain walking groove.

Summary of the invention

The utility model provides a kind of die change dolly of mold changing systems that makes accurately to locate for solving the technical problem that exists in the known technology, with the walk positioner of the accurate hydraulic press die change dolly that docks of groove of the push-pull chain of installing on the table top that is implemented in the push-pull chain walking groove installed on the dolly and the top and fixed platform of template transmission device.

The technical scheme that the utility model is taked for the technical problem that exists in the solution known technology is:

A kind of positioner of hydraulic press die change dolly, fixed head perpendicular to the dolly table top is installed on the car body of die change dolly one end, be fixed with free bearing and fixed block respectively in that the top and bottom of fixed head are vertically opposite with vertical pin-and-hole, be fitted with alignment pin in the vertical pin-and-hole of fixed block, on last free bearing and alignment pin, be hinged with upper junction plate and lower connecting plate respectively, be fixed with the side free bearing at the side between last free bearing and fixed block on the fixed head, be hinged with afterbody on the side free bearing and have earrings, be fixed with the cylinder of hinge frame on the piston rod end that head stretches out, on the last free bearing on hinged upper junction plate and the alignment pin hinged lower connecting plate straight line intersect and be hinged on jointly on the fixing hinge frame of piston rod end, be provided with the locating slot relative in that the track of die change carriage walking is other with described fixed block.

Advantage and the good effect that the utlity model has are: can start cylinder during to the precalculated position of track terminal point at the die change carriage walking, the piston rod of cylinder is released alignment pin by the connecting plate hinged with it, insert it into the accurate location of realizing the die change dolly in the locating slot that is contained on the track, simultaneously owing to be not directly to promote the alignment pin location with cylinder, so just avoided the deficiency of the long installing space that causes of cylinder body, make compact conformation and make cylinder be in a stress preferably, prolonged the service life of cylinder.

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is the vertical view of Fig. 1;

Fig. 3 is that the A-A of Fig. 1 is to cutaway view.

The last free bearing of number in the figure: 1-; The 2-fixed head; The 3-upper junction plate; 4-cuts with scissors frame; The 5-bearing pin; The 6-lower connecting plate; The 7-bearing pin; The 8-alignment pin; The 9-fixed block; The last location-plate of 10-; Location-plate under the 11-; The 12-locknut; 13-side free bearing; The 14-bearing pin; The 15-cylinder.

The specific embodiment

For further understanding summary of the invention of the present utility model, characteristics and effect, exemplify following examples now, and conjunction with figs. is described in detail as follows:

See also Fig. 1 to Fig. 3, the positioner of hydraulic press die change dolly, fixed head 2 perpendicular to the dolly table top is installed on the car body of die change dolly one end, the top and bottom of fixed head are vertically opposite have with bolting respectively on free bearing 1 and fixed block 9 with vertical pin-and-hole, be fitted with alignment pin 8 in the vertical pin-and-hole of fixed block, be hinged with upper junction plate 3 at last free bearing, be hinged with lower connecting plate 6 with bearing pin 7 on the alignment pin, be fixed with side free bearing 13 at the side between last free bearing and fixed block on the fixed head, be hinged with the cylinder 15 that afterbody has earrings with bearing pin 14 on the side free bearing, be fixed with hinge frame 4 with locknut 12 on the piston rod end that its head stretches out, on the last free bearing on hinged upper junction plate and the alignment pin hinged lower connecting plate straight line intersect by bearing pin 5 and be hinged on jointly on the fixing hinge frame of piston rod end, at the other locating slot that is provided with of the track of die change carriage walking, locating slot is made of the last location-plate 10 and the following location-plate 11 that have circle hole groove, they are fixed on the side of track, the diameter of the diameter of the circle hole groove on the last location-plate and alignment pin lower end matches, the alignment pin that stretches out in the time of can making the die change dolly walk to the precalculated position of track terminal point like this is stuck in the circular hole of locating slot, the die change cart stationary firmly is not subjected to displacement, guarantee accurate localization, cylinder links to each other with control device with the source of the gas of the pneumatic system of hydraulic press by flexible pipe.
