Problems solved by technology

Due to the special application and importance of the loader, the improvement of the loader has become an important development trend. In the loader, the rear frame is an important part, which plays the role of connection and stability. There is a large beam on the frame, which is an important part of the rear frame. The volume and weight of the large beam are large. When assembling, they are all mechanically hoisted. It is impossible to grasp it only by experience, and it is prone to deviation. When the error After exceeding the maximum allowable error, the assembly quality of the rear frame will be affected, causing interference problems in the subsequent assembly or use of the loader

Embodiment

[0018] like figure 1 As shown, the positioning device used for assembling the loader beam includes a positioning plate 1 with parallel ends, the positioning plate 1 is an arc-shaped plate, the side wall is an arc surface, and the radian is 3rad to 4rad, the positioning plate 1 is provided with a through hole 2, the through hole 2 runs through the parallel end surface of the positioning plate 1, and the inner wall of the through hole 2 is provided with a thread 4. The positioning plate 1 uses its arc-shaped structure to increase the contact area with the positioning hole. The specific structure can make the assembly and positioning of the girder accurate, and facilitate welding and assembly on the girder. The thread 4 in the through hole is used to install shaft components , easy to connect with other parts, convenient for multiple fixation.

[0019] The arc is 3.14 rad. rad is the unit of radian, and the radian of 3.14 makes the positioning plate 1 in a semicircular state, w...

Abstract

The invention discloses a positioning device for assembly of a loader crossbeam. The positioning device comprises a positioning plate with two parallel ends, the positioning plate is an arc-shaped plate, side walls are arc-shaped surfaces, the radian is in a range of 3rad to 4rad, the positioning plate is provided with a through hole penetrating parallel end faces of the positioning plate, and a thread is arranged on the inner wall of the through hole. According to the positioning device, the structure is simple, the usage is convenient, the manufacturing cost is low, the crossbeam can be mounted and positioned accurately by the aid of the structure, the position of the crossbeam can be limited, so that the quality is stable after assembly of a rear frame, the using safety of a loader is guaranteed, and the interference problem of the loader in follow-up assembly or usage can be avoided.

Description

technical field [0001] The invention relates to a positioning device, in particular to a positioning device used for assembling a loader beam, and belongs to the field of machinery. Background technique [0002] Loader is a kind of earthwork construction machinery widely used in road, railway, construction, hydropower, port, mine and other construction projects. It is mainly used for shoveling bulk materials such as soil, sand, lime, coal, etc. , hard soil, etc. for light shoveling and digging operations. It can also carry out bulldozing, lifting and loading and unloading of other materials such as wood by changing different auxiliary working devices. In the construction of roads, especially high-grade highways, loaders are used for filling and excavation of roadbed engineering, asphalt mixture and aggregate and loading of cement concrete yards. Still can undertake pushing ground of carry soil, strickle and drawing in addition the exercise such as other machine. Because f...
