[0019] The utility model is further explained in connection with the drawings and specific embodiments.

[0020] As Figs. 1-4 Indicated, a kind of splicing jig for ore car hopper, including fixed base 1 and two groups of fixed structures being symmetrically arranged on fixed base 1, each described fixed structure includes fixedly arranged in the same side of fixed base 1 fixed strip 2 and fixed plate 3, the fixed strip 2 is inverted U shape, the fixed plate 3 is located in the right below fixed strip 2 and space is left between the two, the fixed strip 2 inside upper portion movably provided with multiple screw 4, screw 4 length is set according to demand, multiple described screw 4 is evenly arranged along the arc direction of fixed strip 2, the edge of the fixed plate 3 inside is provided with arc slot 31, the bottom of multiple described screw 4 is fixedly provided with contact block 41 towards arc slot 31. Preferably, the width of the fixed plate 3 increases in order from the top of the fixed plate 3 to the bottom of the fixed plate 3, to ensure that the end plate can be spot-welded to the fixed plate 3 and the end plate does not affect the subsequent welding and fixing of the end plate and the arc plate.

[0021] First of all, the ore car hopper generally includes an arc plate and two end plates respectively fixed at both ends of the fixed arc plate. Among them, the shape and size of the end plate are matched with the arc opening of the arc plate.

[0022] The process of splicing the jig to splice the hopper in this embodiment is as follows: first, two end plates are respectively spot-welded to the inner sides of two fixed plates 3 (the end plates are located in the position area of the fixed plate 3 except the arc slot 31), then the arc plate is placed upside down on the fixed base 1, and the two ends of the arc plate are clamped into the two arc slots 31. Then, by adjusting the position of the screw 4, the contact block 41 is abutted against the arc plate, and the contact block 41 adjusts the curvature of the arc plate, and finally the arc plate is tightly attached to the two end plates. It should be noted that because the main stress of the arc plate is concentrated at the bottom of the arc plate, the arc plate is actually corresponding to multiple contact blocks 41 after being placed upside down; generally, after the contact block 41 adjusts the curvature of the arc plate, the curvature of other positions of the arc plate only needs to be manually adjusted by a hammer, and the overall curvature of the arc plate is determined. Finally, the arc plate and the two end plates are manually welded and fixed, in this way, the hopper is spliced. Then the end plate can be separated from the fixed plate 3, and the hopper can be taken off from the splicing jig.

[0023] Wherein, because the curvature requirement of each position of the arc plate is different, the space is left to ensure that the screw rod 4 can move, and then the contact block 41 can adjust the curvature of the arc plate.

[0024] Compared with the previous manual hammering of the curvature of the arc plate, the manual adjustment of the curvature of the arc plate through the screw rod 4 and the contact block 41 can greatly improve the splicing speed and efficiency of the car body and reduce the labor intensity.

[0025] As an implementable manner, a plurality of threaded sleeves 5 are fixedly arranged on the inner upper part of the fixed strip 2, the plurality of threaded sleeves 5 are uniformly arranged along the arc direction of the fixed strip 2 and are all directed to the arc-shaped slot 31, each screw rod 4 is in threaded connection with the threaded sleeve 5 and the screw rod 4 penetrates the threaded sleeve 5. Preferably, the screw rod 4 and the threaded sleeve 5 are both provided with three. The screw rod 4 is manually rotated, the screw rod 4 moves relative to the threaded sleeve 5, and after the screw rod 4 moves, the contact block 41 abuts against the bottom of the arc plate, and the contact block 41 adjusts the curvature of the arc plate.

[0026] Further, an inner thread is arranged on the inner wall of the threaded sleeve 5, and an outer thread matched with the inner thread is arranged on the outer wall of the screw rod 4, and the threaded sleeve 5 and the screw rod 4 are in threaded connection through the inner thread and the outer thread.

[0027] As an implementable manner, the top of each screw rod 4 is fixedly provided with a connecting block 42, a through hole is formed in each connecting block 42, and a rotating rod penetrates the through hole (not shown in the figure). When it is needed to rotate the screw rod 4, the rotating rod can penetrate the through hole, a person rotates the rotating rod, and then drives the screw rod 4 to rotate. The rotating rod is used to drive the screw rod 4 to rotate, and a person operates more easily, realizes the rapid rotation of the screw rod 4, and then realizes the rapid adjustment of the curvature of the arc plate.

[0028] As an implementable manner, a notch 11 is arranged at the center position of the fixed base 1, the notch 11 is designed to reduce the weight and the cost, and two groups of the fixed structures are arranged along the length direction of the fixed base 1, and the two groups of the fixed structures are respectively located at the two ends of the notch 11. Wherein, the size and position of the fixed strip 2 and the fixed plate 3 of the fixed structure can be adjusted to meet the splicing requirements of car bodies of different sizes and models. The splicing jig has a wide application range and can meet the splicing requirements of car bodies of different sizes and models.

[0029] As an implementable mode, the two fixing strips 2 are respectively welded and fixed at two ends of the fixing base 1; a plurality of fixing blocks 12 are fixedly arranged at the two ends of the fixing base 1, a plurality of fixing pieces 21 are fixedly arranged at two ends of the bottom of each fixing plate 3, the bolt 6 passes through the fixing block 12 and the fixing piece 21 and is in threaded connection with the nut, wherein the fixing block 12 and the fixing piece 21 are provided with an opening through which the bolt 6 passes. In the embodiment, the fixing strip 2 is welded and fixed on the fixing base 1, the fixing plate 3 is locked and fixed on the fixing base 1, the fixing strip 2 and the fixing plate 3 can be adjusted according to the size and model of the car hopper, and then are fixed on the fixing base 1, so that the splicing requirement of the car hopper of different sizes and models is met. Of course, the fixing plate 3 can also be welded and fixed on the fixing base 1, at this time, the fixing block 12 does not need to be arranged on the fixing base 1, and the fixing piece 21 on the fixing plate 3 can be directly welded on the fixing base 1.

[0030] Specifically, four fixing blocks 12 are fixedly arranged at the two ends of the fixing base 1, and two fixing pieces 21 are fixedly arranged at the two ends of the bottom of the fixing strip 2. Preferably, one fixing piece 21 and two fixing blocks 12 are fixedly connected through the bolt 6 and the nut, so as to further ensure that the fixing block 12 is kept stable on the fixing base 1.

[0031] The above-mentioned embodiments are only preferred embodiments of the utility model, and are only used to explain the utility model, and do not limit the utility model implementation range. For the person skilled in the art, of course, other embodiments can be easily made by substitution or change according to the technical contents disclosed in the specification, therefore, the changes and improvements made on the principle and process conditions of the utility model should be included in the utility model patent application range.
