Abstract

The utility model discloses an automatic rivet jumping device used for a quadrangular head riveting machine. The automatic rivet jumping device is composed of at least one pair of automatic rivet jumping units. The automatic rivet jumping units comprise air cylinders, bases, positioning blocks, movable blocks and counters. The bases are fixedly connected with one side surface of an upper beam of the quadrangular riveting machine. The air cylinders are fixedly arranged at the upper portion of the bases. The positioning blocks are arranged in sliding channels in the bases. Upper portions of the movable blocks are arranged at the upper beam of the quadrangular riveting machine and abut against the positioning blocks. The working end of one air cylinder is fixedly connected with one end, which is extended out of one sliding channel of one base, of one positioning block. The counters are electrically connected with reversing valves of the air cylinders. The automatic rivet jumping device used for the quadrangular riveting machine has following beneficial effects: a rivet jumping pitch number is set on the counters; the movement of the air cylinders is controlled by the counters; riveting head machining operation is not carried out on set chain links so that quadrangular riveting machining operation carried out on the chain links with different pitch numbers is achieved; and the automatic rivet jumping device is capable of enhancing machining efficiency and machining precision and lowering production cost and labor intensity of workers and is very suitable for automation production of an assembly line for chain link products.

Description

Four jiaos of head riveters are with automatically jumping riveting device

Technical field

The utility model belongs to head riveter technical field, is specifically related to four jiaos of head riveters with automatically jumping riveting device.

Background technology

At present, chain products is carried out to die processing, the general method adopting has two kinds: a kind of method is to carry out die processing by tearing the first hanging joint of whole good chain open again, and articulating joint need to additionally expend man-hour, affects working (machining) efficiency; Another kind method is that the chain assembling is first carried out to die processing regardless of chain length, according to required joint number, tear open whole again, although this method does not affect working (machining) efficiency, but the carrier bar removing and bearing pin cannot reuse because die processing produces deformation, increased production cost, in addition, this deformation cause tear open whole force rate not die to tear whole power open much bigger, make for a long time in this way tearing the infringement of the equipment such as whole oil cylinder open larger.In a word, these two kinds of methods all have problems from aspects such as working (machining) efficiency, production cost, personnel's utilizations, are unfavorable for chain products automatic production line work production.

Summary of the invention

The above-mentioned defect existing in order to overcome prior art field, the purpose of this utility model is, provide a kind of four jiaos of head riveters with automatically jumping riveting device, can complete four jiaos of die processing of different joint number chains, both machining accuracy, working (machining) efficiency had been improved, guarantee service life of equipment, reduce production costs again and labor strength, be applicable to very much the automated production of chain products streamline.

Four jiaos of head riveters that the utility model provides are with automatically jumping riveting device, it is automatically jumped riveting unit by least one pair of and forms, described automatic jumping riveting unit comprises cylinder, pedestal, locating piece, movable block, described pedestal is bolted to connection the side at four jiaos of head riveter upper beams, described cylinder is fixedly arranged on the top of pedestal, described locating piece is arranged in the slideway of base interior, and one end extends in four jiaos of head riveter upper beams, described movable block top is arranged in four jiaos of head riveter upper beams and holds out against locating piece, described movable block and four jiaos of head riveter upper beams are slidably matched, the working end of described cylinder is fixedly connected with one end that locating piece stretches out base slideway, it also comprises counter, and described counter is electrically connected to the reversal valve of cylinder.

Four jiaos of head riveters that the utility model provides are with automatically jumping riveting device, its beneficial effect is: on counter, set and jump riveting joint number, then by the action of counter controls cylinder, to setting chain link, do not carry out die processing, realized four of different joint number chains jiaos of die processing, both improve working (machining) efficiency, machining accuracy, reduced again production cost and labor strength, be applicable to very much the automated production of chain products streamline.
