Abstract
A welded frame of a large-size wheeled tractor comprises a cushion block, reinforcing ribs, a left side plate, a right side plate, support blocks, a rear end plate, a front end plate and supports. The front end plate is mortised with the front parts of the left side plate and the right side plate; the rear parts of the left side plate and the right side plate are mortised with the rear end plate; and the front parts and the rear parts of the left side plate and the right side plate are respectively provided with the reinforcing ribs. Two sides of the front side plate are provided with mortises which are butted with tenons arranged at the front parts of the left side plate and the right side plate. The inner sides of the middle parts of the left side plate and the right side plate are provided with the support blocks, while the outer sides are provided with the supports. The rear ends of the left side plate and the right side plate are respectively provided with a pin hole deep into a body between two sides of the rear end plate, a pin is knocked into the pin hole, and the pin hole is riveted to be small so that the pin can not escape out. With the adoption of the combination of the tenons, the pin and the rivet, welding jigs are not needed when the frame is assembled, in addition, the welding seams are the least, the deformation is the smallest, and both the strength and the rigidity of the frame can effectively meet requirements. The problems of deformation and centralized stress in the welding are effectively resolved.
Description
Technical field
The utility model belongs to the trac. field, relates to a kind of large-scale wheel-tire tractor welded frame.
Background technology
At present, in China's trac. industry,, still be client's application requirements no matter, all to there being the posture wheel-tire tractor that to a certain degree demand is arranged from the skill upgrading angle along with the raising of wheel-tire tractor power and the improvement of function.Vehicle frame is the vitals of trac., and when the great advantage of using these parts was trac. overhaul and engine maintenance or replacing, trac. need not disconnected waist to carry out, and this is the trac. form that the agricultural machinery client welcomes most.Have the posture tractor frame beam that application is all arranged at home and abroad, but the overwhelming majority is a Casting Parts.Grinding tool is simple, cost is low, product is out of shape advantages such as fast, that manufacturing process is simple and welded frame has.Yet, only welding technique is used for vehicle frame, shortcoming such as it is poor to have a weld strength, and shock-resistant mechanical characteristics and fatigue resistance are weak.
The utility model content
The purpose of this utility model is to provide a kind of can overcome above-mentioned shortcoming, the large-scale wheel-tire tractor welded frame that adopts technology such as tenon, pin, weldering, riveting to combine.
The technical solution of the utility model is: large-scale wheel-tire tractor welded frame comprises: cushion block, preceding reinforced rib, right side board, back-up block, back reinforced rib, lower back panel, front end-plate, left side board, support.With front end-plate and left side board, the anterior joggle of right side board, left side board, right side board rear portion and lower back panel joggle, left side board, the forward and backward position of right side board are furnished with preceding reinforced rib, back reinforced rib respectively.
Described front end-plate both sides are provided with mortise A, connect with left side board, the anterior tenon that is provided with of right side board.
Described left side board, inboard, right side board middle part have been provided with back-up block, arranged outside has support.
Respectively there are 2～5 pin-and-hole B described left side board, right side board rear end, and this pin-and-hole is deep in lower back panel two lateral bodys, squeeze into pin, pin can not be jumped out the riveting of pin-and-hole mouth.
The utility model can reach following beneficial effect: adopt tenon, pin, riveting combination to need not welding jig in the time of can making the group vehicle holder, and it is minimum to reach weld seam, distortion is minimum, and the strength and stiffness of vehicle frame can both satisfy by actv..Actv. has overcome the distortion in the welding and the problem of stress concentration.
Description of drawings
Accompanying drawing is the structural representation of the large-scale wheel-tire tractor welded frame of the utility model.
The specific embodiment
As shown in drawings, the large-scale wheel-tire tractor welded frame of the utility model uses technology mode groups such as some steel plate tenons, pin, weldering, riveting to stand and forms, the anterior trac. front rack that connects, and the rear portion connects gear box of tractor, middle installation tractor engine.Large-scale wheel-tire tractor welded frame comprises: cushion block 1, preceding reinforced rib 2, right side board 3, back-up block 4, back reinforced rib 5, lower back panel 6, front end-plate 7, left side board 8, support 9.Front end-plate 7 and left side board 8, right side board 3 anterior joggles, left side board 8, right side board 3 rear portions and lower back panel 6 joggles, left side board 8, right side board 3 forward and backward positions are furnished with preceding reinforced rib 2, back reinforced rib 5 respectively.
Front end-plate 7 both sides are provided with mortise A, connect with left side board 8, the right side board 3 anterior tenons that are provided with; Left side board 8, inboard, right side board 3 middle part have been provided with back-up block 4, arranged outside has support 9; Respectively there are 2～5 pin-and-hole B left side board 8, right side board 3 rear ends, and this pin-and-hole is deep in 6 liang of lateral bodys of lower back panel, squeezes into pin, pin can not be jumped out the riveting of pin-and-hole mouth.
Front end-plate 7 is used to connect front rack (being used to install front driving axle), and lower back panel 6 connects gear box of tractor, and left and right cushion block 1 and left and right back-up block 4 are used to install tractor engine.Reinforced rib 2 and left and right back reinforced rib 5 are mainly used in the wrench deformation of vehicle frame perpendicular to working direction before left and right.Respectively there are 2～5 pin-and-hole B left side board 8, right side board 3 rear ends, and this pin-and-hole is deep in left side board 8,3 liang of lateral bodys of right side board, squeezes into pin, pin can not be jumped out the riveting of pin-and-hole mouth.All the other lap-joints use fillet welding to carry out full weld, carry out corresponding heat treatment and machinework and form.
