Description

Splicing clamping fixture for mine car hopper Technical Field The utility model relates to the technical field of splicing jigs, in particular to a splicing jig for a mine car hopper. Background The (skip bucket) mine car is widely used in the industrial fields of mines, construction sites, ports and the like, and is mainly used for efficiently transporting bulk materials such as coal, ores, building materials and the like. Because the mine car hopper adopts curved design, can produce the error when the arc board of hopper rolls up the arc, the arc board need repair repeatedly and just can align when the end plate concatenation with both sides, and then influence concatenation efficiency. The existing splicing clamping fixture is simple in structure, and can only play the role of fixing the arc plates and the two end plates, the radian of the arc plates cannot be directly adjusted, the arc plates still need to be repeatedly knocked by a hammer manually, time and labor are wasted, the knocked arc plates are large in error, and therefore the arc plates on the existing splicing clamping fixture can be aligned with the two end plates after being repeatedly trimmed when being spliced, and the splicing speed is low. Therefore, there is a need for a splicing mold for a mine car hopper to solve the above problems. Disclosure of utility model The utility model provides a splicing jig for a mine car hopper, which is characterized in that compared with the conventional splicing jig for a mine car hopper, the conventional splicing jig for the mine car hopper is characterized in that the arc of an arc plate can be quickly adjusted by manually beating the arc of the arc plate through a screw and a contact block, so that the arc of the arc plate is quickly adjusted by manually beating the arc of the arc plate through the screw and the contact block, and the splicing speed and the splicing efficiency of the hopper are greatly improved. The utility model provides a splicing mould for a mine car hopper, which comprises a fixed base and two groups of fixed structures symmetrically arranged on the fixed base, wherein each fixed structure comprises a fixed strip and a fixed plate which are fixedly arranged on the same side of the fixed base, the fixed strips are in an inverted U shape, the fixed plates are positioned under the fixed strips, a space is reserved between the fixed strips, a plurality of screws are movably arranged on the upper part of the inner side of the fixed strips, the screws are uniformly arranged along the arc direction of the fixed strips, arc grooves are formed in the edge of the inner side of the fixed plates, and contact blocks facing the arc grooves are fixedly arranged at the bottoms of the screws.
