CN201890559U - Middle connector of suspension conveyor chain - Google Patents

Abstract

The utility model relates to a middle connector of a suspension conveyor chain, which consists of a connector body with through holes. The connector body is punched by using a metal sheet. The cross section of the connector body is U-shaped. Corresponding through holes are arranged on the two arms of the U-shaped connector body. Raised pits are arranged in the middles of the upper edges and the lower edges of the two arms. The middle connector is originally made of integral square steel on which holes are punched, and has the disadvantages that the weight is heavy, the machining workload is great, the machining speed is low, the arc surfaces of the two ends of the square steel are required to be machined, the time and the effort are consumed, the material wastage is serious and the machining difficulty is great. The middle connector is currently punched by using the metal sheet and has the advantages that the middle connector is easy to machine and manufacture, the two ends are not required to be additionally machined, the time, the material and the labor are saved and the production cost is greatly reduced. The conveyor chain needs a plurality of middle connectors. Since the structure of the middle connector is improved and the weight is reduced, the weight of the entire conveyor chain is greatly reduced, the material is saved, the machining workload is reduced, the machining accuracy is improved and the conveying power of a conveyor can be reduced.

Description

The center coupling of suspension conveyer chain bar

Technical field

The utility model relates to the vitals in a kind of overhead chain conveyor, connects the attaching parts of each carrier bar on the chain, the center coupling of suspension conveyer chain bar.

Background technology

The suspension conveyer chain bar is to be promoted by actuating device, makes the parts of operation continuously in sealing side's rail, and it plays a part to hang the load-bearing object and transmits object in conveyer.Therefore it can also finish the space curve operation in various levels and the vertical surface along with the various directions and the various curve shape of track except moving linearly.Chain is whole the vitals in the overhead chain conveyor, and its quality quality directly has influence on the safety and steady operation of conveyer and the service life of conveyer.

Conveyor line production is all adopted in now a lot of enterprise, the especially productions of household appliances industry, uses the conveying that a large amount of suspension conveyer chain bars carries out load-bearing and transmits object.But the center coupling that chain uses on the existing market still is processed into through punching with the single-piece square steel, and then two ends is carried out the processing of arc surface, and not only processing trouble processing capacity is gone back waste material greatly.Chain be the product that has a large capacity and a wide range be again the rapid wear product, center coupling on it is again the strength member on the chain, every pitch chain bar all needs to couple together with the carrier bar of this center coupling with each band chain wheel, so the use amount of center coupling is very big on the chain.

Summary of the invention

Technical problem to be solved in the utility model is: the center coupling of a kind of suspension conveyer chain bar is provided, with the supporting use of suspension conveyer chain bar, its simple in structure, easy processing and fabricating, economical with materials also, thus also alleviate the weight of whole piece suspension conveyer chain bar and reduced productive costs.

The technical scheme in the invention for solving the above technical problem is: the center coupling of suspension conveyer chain bar, form by last fittings body by through hole, described fittings body is made by metallic plate punching, its cross section is the U font, on two arms of U font corresponding through hole is arranged, there is the pit of projection in the upper and lower edge in the middle of two arms.

Compared with prior art, advantage of the present utility model is, formerly becomes deal heavy with single-piece square steel material perforation processing, and processing capacity is big, process velocity is slow, also needs do arc surface processing to its two ends of square steel, time-consuming, effort, the greatly also difficult processing of waste of material.Now make with metallic plate punching, easy processing and fabricating, two ends need not remake other processing yet, saves time, material-saving, saving of labor greatly reduce productive costs.Chain need be with a lot of center couplings, because of the improvement of center coupling structure, alleviating of weight alleviates the weight of whole chain self greatly, not only saved material and reduced processing capacity, also improve working accuracy, can reduce the transmission power of conveyer again.

The specific embodiment

Below in conjunction with accompanying drawing embodiment of the present utility model is further described:

Fittings body 1 usefulness metallic plate punching is made, the cross section of fittings body is the U font, and an end opening, end sealing have corresponding through hole 3 on two arms of fittings body 1 open end, upper and lower edge at two arm through holes, 3 places has extrusion process to go out the pit 2 of projection, is used to make bearing pin 6 location.

When bearing pin 6 inserted in fittings body 1 closed end, the pit 2 at the upper and lower edge of fittings body was spacing to it, makes bearing pin can not move to open end on a large scale.

During use, bearing pin 6 is passed successively the cavity of following carrier bar 7, fittings body 1 closed end respectively, through hole on the top carrier bar 7, and the carrier bar 7 and the fittings body 1 of above and below connected into the integral body that can vertically rotate with spring cotter 5, also be horizontally through through hole on the carrier bar 4 that left and right direction places and the through hole 3 on the fittings body 1 with bearing pin 6, with spring cotter 5 but left and right carrier bar 4 and fittings body 1 are connected into the integral body of lateral rotation, this is for connecting into doubly-linked carrier bar list guide wheel chain as shown in Figure 3.

Also can connect into the chain of other specifications and shape as required.

Claims (1)

1. suspension conveyer chain bar center coupling, by on have the fittings body (1) of through hole to form, it is characterized in that described fittings body (1) made by metallic plate punching, its cross section is the U font, corresponding through hole (3) is arranged on two arms of U font, and there is the pit (2) of projection in the upper and lower edge in the middle of two arms.
