The utility model content
Deviation easily appears in the purpose of this utility model when being to overcome the crossbeam that has Rear frame of loader now, cause loader interference problem to occur in follow-up assembling or in using, designed a kind of positioner that assembles the loader crossbeam, this positioner simple in structure, easy to use, low cost of manufacture, utilize its structure can be effectively with the install crossbeam accurate positioning, the position of crossbeam can be limited, so that the steady quality behind the vehicle frame after the assembling, guarantee the use safety of loader, loader can not occur and interference problem occur in follow-up assembling or in using.
The purpose of this utility model is achieved through the following technical solutions: a kind of positioner that assembles the loader crossbeam, comprise the location-plate that two ends are parallel, described location-plate is an arc, sidewall is cambered surface, and radian is 3rad to 4rad, be provided with through hole on the location-plate, through hole runs through the parallel end faces of location-plate, and the inwall of through hole is provided with screw thread.
Further, described radian is 3.14rad.
Further, one of them end face evagination of described location-plate forms boss, and boss is along the end face setting of cambered surface, and the sidewall of boss and cambered surface are in same plane.
Further, the height of described boss is 1mm to 3mm, and the width of boss is 1mm to 3mm.
Further, the height of described boss is 2mm.
Further, the width of described boss is 2mm.
Further, be provided with the circular groove of end face concave shaped of boss in the described location-plate, and the central lines of the center line of groove and through hole, the diameter of groove is greater than the diameter of through hole.
Further, the degree of depth of described groove is 1mm to 3mm.
Further, the degree of depth of described groove is 2mm.
In sum, the beneficial effects of the utility model are: this positioner simple in structure, easy to use, low cost of manufacture, utilize its structure the position of crossbeam can be limited effectively with the install crossbeam accurate positioning, so that the steady quality behind the vehicle frame after the assembling, guarantee the use safety of loader, loader can not occur and interference problem occur in follow-up assembling or in using.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Mark and corresponding component title in the accompanying drawing: 1-location-plate; 2-through hole; 3-groove; 4-screw thread; 5-boss.
The specific embodiment
Below in conjunction with embodiment and accompanying drawing, the utility model is described in further detail, but embodiment of the present utility model is not limited only to this.
Embodiment:
As shown in Figure 1, a kind of positioner that assembles the loader crossbeam, comprise the parallel location-plate in two ends 1, described location-plate 1 is an arc, sidewall is cambered surface, and radian is 3rad to 4rad, is provided with through hole 2 on the location-plate 1, through hole 2 runs through the parallel end faces of location-plate 1, and the inwall of through hole 2 is provided with screw thread 4.Location-plate 1 utilizes its arcuate structure, so that increase with the contact area of locating hole, specific structure can be so that the assembling and positioning of crossbeam be accurate, conveniently weld and assemble at crossbeam, screw thread 4 in the through hole is used for the installation shaft base part, be convenient to be connected with miscellaneous part, convenient multiple fixing.
Described radian is 3.14rad.Rad is the unit of radian, 3.14 radian, so that location-plate 1 is the semicircle state, stressed effect is better, locates more stable.
