Technical Field

[0001] This utility model relates to the technical field of mining truck production, and in particular to a positioning tool for the head shell structure of a mining truck. Background Technology

[0002] In the manufacturing process of mining cars, the positioning of the head shell structure is a critical step. The head shell structure of mining cars has a relatively complex shape and large size. During welding and other processing operations, it is necessary to ensure its stability to guarantee welding quality and the overall precision of the product. In existing technologies, the positioning of the head shell structure of mining cars is mostly done manually with the help of simple tools for support and fixation, which has many shortcomings: on the one hand, the positioning accuracy is low, making it difficult to ensure the accurate relative position of each part of the head shell structure of the mining car, which can easily lead to deviations in subsequent welding and affect product quality; on the other hand, the operation process is cumbersome, which not only consumes a lot of manpower but also reduces production efficiency. At the same time, the shell structure is prone to shaking or displacement during processing, which further affects processing accuracy and safety. Therefore, there is a need for a positioning tool that can accurately and stably position the head shell structure of a mining car and is easy to operate, in order to solve the problems existing in the current technology. Utility Model Content

[0003] In order to improve the problems that occur in the processing of the head shell structure of mining trucks in the above-mentioned background art, this utility model provides a positioning tooling for the head shell structure of mining trucks.

[0004] The positioning fixture for the head shell structure of a mining car provided by this utility model adopts the following technical solution: A positioning fixture for a mining car head shell structure includes a base. A bottom support column, a movable limiting column, and a lateral limiting column are fixedly mounted on the base. The lateral limiting columns abut against the two end plates of the mining car head shell structure to restrict the movement of the mining car head shell structure in the lateral direction. The bottom support column supports the rear end of the mining car head shell structure and, together with the movable limiting column abutting against the front end of the mining car head shell structure, restricts the movement of the mining car head shell structure in the front-rear direction.

[0005] Preferably, an L-shaped support is detachably installed on the base. The L-shaped support supports the square tube and welds the end of the square tube to the inner side of the end plate of the mining car head shell structure, facilitating the welding operation of the square tube while positioning.

[0006] Preferably, the L-shaped support includes an ear plate, a rotating shaft, and a bending plate. The ear plate is detachably fixed to the base by bolts. The rotating shaft is rotatably disposed between the two ear plates. One end of the bending plate is connected to the rotating shaft, and a rectangular notch is opened at the bent end of the bending plate, into which a square tube is placed.

[0007] Preferably, the movable limiting post includes a vertical plate fixed on the base. The top of the vertical plate has a screw hole and a stud is screwed in. The inner end of the stud abuts against the front end face of the mine car head shell structure. By rotating the stud 15, the force and position of its abutment against the mine car head shell structure can be adjusted to ensure that the mine car head shell structure remains stable during subsequent processing.

[0008] Preferably, a first reinforcing rib is provided between the vertical plate and the base to enhance the stability and load-bearing capacity of the vertical plate.

[0009] Preferably, a second reinforcing rib is provided between the lateral limiting post and the base to improve the structural strength of the lateral limiting post.

[0010] Preferably, the base is further provided with a bottom support member, the top of which is bent and supported on the bottom of the two end plates of the head shell structure of the mining car, providing auxiliary support for the two end plates of the head shell structure of the mining car.

[0011] In summary, this utility model has the following beneficial technical effects: 1. This utility model achieves precise positioning of the head shell structure of a mining car. By using lateral limiting posts to abut against the two end plates of the head shell structure, the lateral movement of the head shell structure is restricted. By using bottom support posts in conjunction with movable limiting posts, the movement of the head shell structure in the front-rear direction is restricted. This utility model can quickly achieve limiting and support of the head shell structure of the mining car from multiple directions, ensuring positioning accuracy and improving the quality of subsequent welding and other processing operations.

[0012] 2. The movable limiting post of this utility model is abutted against the front end face of the mine car head shell structure by means of a stud. The abutting distance and abutting force can be adjusted to adapt to the positioning of mine car head shell structures of different lengths, thus improving the versatility of the tooling. The L-shaped support can be detachably installed on the base, which can realize the convenient positioning of the square tube and weld and fix the square tube to the inside of the mine car head shell structure. At the same time, the detachable structure can make way and not block the installation of subsequent components. Attached Figure Description

[0015] The following combination Figures 1-5 The present invention will be described in further detail below.

[0016] This utility model discloses a positioning tooling for the head shell structure of a mining truck.

[0017] Reference Figure 1 , Figure 4 , Figure 5 A positioning fixture for the head shell structure of a mining car includes a base 1. The base 1 is made of steel plate by cutting and welding to ensure that it has sufficient strength and stability. A bottom support column 2, a movable limiting column 3 and a lateral limiting column 4 are fixedly installed on the base 1. The lateral limiting post 4 abuts against the two end plates 6 of the head shell structure 5 of the mine car; there are two lateral limiting posts 4, which are fixedly welded to the two sides of the base 1 respectively. The inner side of the lateral limiting post 4 abuts against the two end plates 6 of the head shell structure 5 of the mine car, restricting the movement of the head shell structure 5 of the mine car in the lateral direction and limiting the lateral movement of the head shell structure 5 of the mine car. The bottom support column 2 supports the rear end of the mine car head shell structure 5, and works in conjunction with the movable limiting column 3 that abuts against the front end of the mine car head shell structure 5 to restrict the movement of the mine car head shell structure 5 in the front-rear direction.

[0018] Reference Figure 1 , Figure 3 , Figure 5 An L-shaped support 7 is detachably installed on the base 1. The L-shaped support 7 supports the square tube 8 and welds and fixes the end of the square tube 8 to the inner side of the end plate 6 of the head shell structure 5 of the mining car.

[0019] The detachable structure of the L-shaped support 7 allows for clearance. If other components are to be installed in the same installation position during subsequent processing, the L-shaped support 7 can be removed without obstructing the installation of subsequent components.

[0020] The L-shaped support 7 includes ear plates 9, a rotating shaft 10, and a bending plate 11. The ear plates 9 are detachably fixed to the base 1 by bolts 12.

The rotating shaft 10 is rotatably positioned between the two ear plates 9. One end of the bending plate 11 is connected to the rotating shaft 10, and a rectangular notch 13 is provided at the bent end of the bending plate 11. A square tube 8 is placed in the notch 13. By rotating the bending plate 11, the end of the square tube 8 is aligned with the inner side of the end plate 6, which facilitates the positioning of the square tube 8. The square tube 8 is then welded and fixed to the inside of the head shell structure of the mining car.

[0021] Reference Figure 1 , Figure 2 , Figure 4 The movable limiting column 3 includes a vertical plate 14 fixed on the base 1. A first reinforcing rib 16 is provided between the vertical plate 14 and the base 1 to enhance the stability of the vertical plate 14 structure. The top of the vertical plate 14 has a screw hole and a stud 15 is screwed in. The inner end of the stud 15 abuts against the front end face of the mine car head shell structure 5. By rotating the stud 15, the clamping force against the front end face of the mine car head shell structure 5 can be adjusted. Together with the bottom support column 2, the movement of the mine car head shell structure 5 in the front and rear directions is restricted, so as to prevent the mine car head shell structure 5 from shaking during subsequent processing such as grinding and painting.

[0022] Reference Figure 1 , Figure 4 A second reinforcing rib 17 is provided between the lateral limiting post 4 and the base 1 to further improve the structural strength and stability of the lateral limiting post 4, and ensure the reliability and safety of the tooling in the subsequent processing.
