Abstract
The utility model discloses a tractor truck frame for extruding plastic profiles. The tractor truck frame comprises a machine rack, a lever mechanism fixedly arranged on the machine rack, and an upper truck frame arranged on the machine rack; an automatic balancing device is arranged between the upper truck frame and the lever mechanism as well as the machine rack; the automatic balancing device comprises a connection board, a pull rod, a support and a butterfly spring; the lower end of the connection board is fixed on the side face of the upper truck frame; the both ends of the pull rod are respectively movably connected with the upper end of the connection board and the support by a shaft with a round through hole and the butterfly spring and the support is fixed on the machine rack. With the adoption of the technical scheme, the butterfly spring has certain elastic deformation and the elastic deformation is not large; and therefore, the balancing force in the utility model is basically kept unchanged. Accordingly, the balance of the upper truck frame can be effectively adjusted, and the structure is simple.
Description
Technical field
The utility model relates to a kind of plastic irregular profile and extrudes subsidiary engine hauling machine track frame, especially comprises frame, is fixed on the leverage on the frame and places the plastic irregular profile of the last track frame on the frame to extrude using the hauling machine track frame.
Background technology
The track frame that plastic irregular profile is extruded the subsidiary engine hauling machine comprises frame, is fixed on the leverage on the frame and is positioned at the last track frame on the frame that section bar is clipped between track frame and the frame.Section bar is before getting into hauling machine, and last track frame needs to open, and treats that section bar gets into when going up the track frame region, will go up track frame again and move downward, and to clamp section bar, the rotation through crawler belt pulls out section bar.In the process that last track frame moves up and down, because the leverage that adopts has only a fulcrum to be used for supporting on the last track frame, in the process of moving up and down, be difficult to reach balance so go up track frame, influence normal section bar production.
Usually the way that solves this difficult problem is to lay particular stress on cylinder of side increase at last track frame to be used for balance.Because being used for the cylinder of balance is to guarantee by the compressed air that has certain pressure; Track frame is in the process of moving up and down on the lever drives; The equilibrant force that cylinder provided can not be synchronous fully with the motion of last track frame, causes in the process of moving up and down, being difficult to reach balance.
The utility model content
The technical problem that the utility model will solve provides a kind of plastic irregular profile simple in structure, that can effectively realize balance and extrudes and use the hauling machine track frame.
The technical scheme that the utility model adopted is: plastic irregular profile is extruded and is used the hauling machine track frame; Comprise frame, be fixed in the leverage on the frame and place the last track frame on the frame; Be provided with automatic balancing arrangement between last track frame and leverage and the frame; Said automatic balancing arrangement comprises connecting plate, pull bar, bearing, butterfly spring; The lower end of described connecting plate is fixed on the side of track frame, and the two ends of pull bar flexibly connect through axle, butterfly spring and the connecting plate upper end of band round tube hole, the bearing that is fixed on the frame respectively.
Adopt technique scheme, because butterfly spring has certain elastic deformation, and the elastic deformation amount is little, and the equilibrant force that is provided remains unchanged basically, the balance that therefore can regulate track frame effectively, and simple in structure.
Description of drawings
Fig. 1 is the structural representation of the utility model.
The specific embodiment
Elaborate below in conjunction with the specific embodiment of accompanying drawing to the utility model.
As shown in Figure 1; The plastic irregular profile of the utility model is extruded with the hauling machine track frame and is comprised frame 11, is fixed on the leverage 2 on the frame 11 and places the last track frame 1 on the frame 11; Be provided with automatic balancing arrangement between last track frame 1 and leverage 2 and the frame 11, described automatic balancing arrangement comprises connecting plate 3, axle 1, axle 25, pull bar 6, bearing 7, axle 38, butterfly spring 9, nut 10, and described connecting plate 3 is fixed on track frame 1 two sides; Each connecting plate 3 is provided with and axle one 4 suitable circular holes and the platform affixed with axle 25; Circular hole is joined to be incorporated in the circular hole and is rotated on described axle 1 and the connecting plate 3, and each one 4 is provided with the circular hole suitable with pull bar 6, and described axle 25 is fixed on the connecting plate 3; Each 25 be provided with leverage 2 on circular hole suitable the axle; Described bearing 7 is fixed on the frame 11, and each bearing 7 is provided with and axle 38 suitable circular holes, with the suitable axle of leverage 2; Described axle 38 is joined to be incorporated in the circular hole with the circular hole on the bearing 7 and is rotated; Each 38 is provided with the circular hole suitable with pull bar 6, and described pull bar 6 cooperates with circular hole on axle 1 and the axle 38, and is equipped with the screw thread suitable with nut 10 at the two ends of passing axle 1 and spools 38; Described butterfly spring 9 passes pull bar 6 and is placed on axle 38 two ends respectively; Threaded engagement on the balance when reaching adjustment and go up track frame 1 and move up and down through leverage 2 through the quantity that axle 38 two ends butterfly springs 9 are set, described nut 10 and pull bar is placed on the two ends of axle 1, butterfly spring 9 respectively.
