Abstract
The invention discloses a connecting structure of a step tripod and a main wheel axle seat, which comprises a tripod and a main wheel axle seat, wherein one axial end of the main wheel axle seat is vertically turned outwards and extends to form a flange, a stamping convex connection part is arranged on one side of the flange facing the tripod, and a stamping concave connection groove which is meshed and fixed with the stamping convex connection part is arranged on the tripod. The invention has high connection strength and simple processing technology, and saves the production cost.
Description
Technical field
The present invention relates to the connection structure of a kind of step spider and main wheel axle bed, relate in particular to the connection structure of a kind of light-duty escalator step spider and main wheel axle bed.
Background technology
The main wheel axle bed is by aluminium, cast steel die cast in the prior art, and the material cost height also need carry out the processing of machine pincers, and tooling cost is expensive and deadweight is bigger.Existing main wheel axle bed generally is connected on the step spider by fastener, fastener is connected with easily loosening unreliable factor, therefore some main wheel axle bed is fixed by especially spot welded mode of welding and spider, though it is a kind of more firm type of attachment that spot welding connects, but spot welded solder joint outward appearance is random and not attractive in appearance, after aluminium sheet spot welding was intact, the processing of also need electroplating or spray paint was to remedy the defective that spot welding destroys the corrosion resistance of aluminium sheet.
Summary of the invention
The object of the invention provides the connection structure of a kind of step spider and main wheel axle bed, and its Joint strenght height, processing technology are simple, have saved productive costs.
Technical scheme of the present invention is: the connection structure of a kind of step spider and main wheel axle bed, comprise spider and main wheel axle bed, the flange that the axial end of described main wheel axle bed vertically turns up and extends to form, described flange is provided with the punching press convex jointing part towards a side of spider, and described spider is provided with and the fixing stamped female access slot of described punching press convex jointing part interlock.
Further, above-mentioned spider and main wheel axle bed all are that steel plate is stamped to form output height, steady quality.
Further, the bottom land of described stamped female access slot is wider than notch, and the cooresponding filling of described punching press convex jointing part shape also is connected in the stamped female access slot.Such connection structure is firm stable, and the punching press convex jointing part is difficult for deviating from the stamped female access slot.Also can be out of shape the welding that causes each other between the outer wall of the convex jointing part of punching press simultaneously and the inwall of stamped female access slot, make that the connection between the two is more firm by punching press.
Further, above-mentioned punching press convex jointing part and stamped female access slot are after the platen surface of described flange and spider reclines mutually, the arranged outside punch of flange, the cooresponding die of the arranged outside of spider and punch, pass through punch process, the die that punch squeezes into plate to be connected, under further squeezing action, the spider plate material of the flange plate material Extruding die side of punch side, make the plate distortion of in die, " flowing ", promptly produce one and both do not have seamed edge, a carrot-free again point of connection by what stamped female access slot and punching press convex jointing part formed.
Obviously, also die and punch switch can be provided with in the said process, the punching press convex jointing part that then processes is positioned on the spider, and the stamped female access slot is positioned on the main wheel axle bed.
Further, the flange of described main wheel axle bed also is provided with locating convex block towards a side of spider, and described spider is provided with and the cooresponding knock hole of locating convex block.When the two is installed together, can at first position in the knock hole with the insertion of the locating convex block on main wheel axle bed spider.Simultaneously passing the outer end of knock hole at locating convex block can also the riveting distortion and fix with knock hole steel plate on every side.
Advantage of the present invention is:
1. spider and main wheel axle bed bonded assembly intensity height: the plate material at connection location is extruded, and its mechanical characteristics is improved, and simultaneously at the point of connection place, material does not have the damage of tearing, and promptly unstressed concentrating is so dynamic Joint strenght height.
2. help environmental protection: compare with spot welding, the present invention adopts punching press to connect, and need not to electroplate or spray paint processing.
3. economy is good: spider of the present invention has been connected work simplification with the main wheel axle bed, and spider and main wheel axle bed can pass through the steel plate punch process simultaneously, has therefore reduced productive costs.

The specific embodiment
Below in conjunction with drawings and Examples the present invention is further described:
Embodiment: as shown in Figures 1 to 4, the connection structure of a kind of step spider and main wheel axle bed, comprise spider 1 and main wheel axle bed 2, the flange 3 that described main wheel axle bed 2 axial ends vertically turn up and extend to form, described flange 3 is provided with punching press convex jointing part 4 towards a side of spider 1, and described spider 1 is provided with and the fixing stamped female access slot 5 of described punching press convex jointing part 4 interlocks.
The bottom land of described stamped female access slot 5 is wider than notch, and the cooresponding filling of described punching press convex jointing part 4 shapes also is connected in the stamped female access slot 5.
Described spider and main wheel axle bed all are that steel plate is stamped to form, and stamped female access slot 5 and punching press convex jointing part 4 platen surface for flange 3 platen surface of main wheel axle bed 2 and spider 1 are close to the back punching press and are processed to form.
The flange 3 of described main wheel axle bed 2 also is provided with locating convex block 6 towards a side of spider 1, and described spider 1 is provided with and locating convex block 6 cooresponding knock holees.Be used for playing positioning action in that spider 1 and main wheel axle bed 2 joints are added man-hour.Simultaneously passing the outer end of knock hole at locating convex block can also the riveting distortion and fix with knock hole steel plate on every side, further strengthens the Joint strenght between spider 1 and the main wheel axle bed 2.
Joint strenght height of the present invention, processing technology are simple, have saved productive costs.
