Description

C-slot assembly tooling

technical field

The invention belongs to the field of the middle groove of a scraper, in particular to a C-shaped groove assembly tool.

Background technique

At present, the structural form of the central groove in China is mainly a cast-welded structure, which is mainly composed of baffle grooves, shovel grooves, middle plates, bottom plates, and rack socket components. Because the coal and gangue mined by the shearer all fall on the middle trough, they are in direct contact with the middle plate, and then run in the middle trough with the moving scraper. Therefore, the friction force on the middle plate is very large, and the cycle is repeated continuously, and the wear of the middle plate will be very serious. The middle plate has only one layer and cannot be replaced. After the middle plate is worn, it can only be repaired by surfacing welding. The number of middle grooves is large, the area of the middle plate is large, the surface quality of surfacing repair is poor, and the deformation and distortion of the middle groove will be caused, and the strength will be reduced. In order to improve the strength of the middle groove, patent 20152084469614 discloses a high-strength composite C-shaped groove structure, which mainly consists of a C-shaped groove, a groove side assembly and a rack seat assembly, wherein the C-shaped groove includes an upper middle plate and a set on the upper middle plate. Groove edges at the upper ends. The C-shaped groove is assembled on the assembly platform. The assembly process is as follows: 1. Draw a right-angle line on the platform; 2. Align a groove along the end face and the outer side respectively; 3. Spot welding the groove on the platform ;4. Place the other groove edge parallel to the first groove edge, the chain openings are opposite to each other, and the end faces are aligned; 5. Adjust the second groove edge, and measure the width of the groove correctly; 6. Point the groove edge Weld on the platform; 7. Cover the upper middle plate on the edge of the groove, adjust the alignment of the scribed ends, and overlap the two sides evenly; 8. Position the middle plate and the edge of the groove; 9. Both ends of the C-shaped groove are close to each other. 10. Cut off the spot welding points of the groove edge and the platform by fire, and smooth the cut marks; 11. Turn it over and position-weld the middle plate and the inner side of the groove edge. The disadvantage of the existing C-shaped groove assembling method is that: before each piece of C-shaped groove is assembled, the grooves are marked along the alignment line on the assembly platform, and the grooves are welded on the assembly platform along the key points during the assembly process, and the C-shaped groove is assembled. After that, cut off the edge of the groove from the assembly platform, and then polish the assembly platform. This assembly method has low efficiency; second, the grooves are welded on the assembly platform along the key points, and then cut off by fire, which will damage the assembly platform; third, there are differences in personal measurement, resulting in a large error in the size of the C-shaped groove.

The frame body 1 is provided with two backing plates 2 whose length directions are not perpendicular to each other or overlap each other, and the upper surfaces of the two backing plates 2 constitute a positioning plane. The positioning plane can be the upper surface of the frame body 1. During the assembly process, the positioning surface needs certain precision, such as surface roughness and flatness, to ensure the assembly accuracy and the size of the C-shaped groove after assembly. If the entire upper surface of the frame body 1 is processed to the same precision, the processing cost will increase. Therefore, two backing plates 2 are arranged on the frame body 1 , and the upper surfaces of the two backing plates 2 constitute the positioning plane of the upper surface of the groove edge 80 . During processing, only the upper surface of the backing plate 2 needs to be processed to the required accuracy, and the surface to be processed is reduced, which can effectively reduce the processing cost. Preferably, the two backing plates 2 are arranged in parallel, and the length direction of the backing plates 2 is perpendicular to the length direction of the groove edge 80; the backing plate 2 is in the shape of a long strip.

The outer width positioning plate 5 keeps a certain distance from the groove edge 80 for wedging of the width limiting wedge 6 in the later stage.

(3) The two end faces of the groove along the length direction of 80 are respectively abutted against the length positioning blocks 3 at both ends to complete the length direction positioning. At this time, the inner width positioning plate 4 on the length positioning block 3 is always in an open state.
