Description

Water pump preassembling tool Technical Field The utility model relates to the technical field of air conditioner production, in particular to a water pump preassembling tool. Background Currently, air conditioner water pumps are typically fixedly mounted through a water pump bracket. However, in the conventional fixing process of the water pump, particularly in the pipeline operation environment, there are the following technical problems: 1. the screw fastening is limited, and potential safety hazards exist, namely, due to the limitation of a production line, the screw for fixing the water pump is easy to interfere with the production line in the fastening process, so that the screw cannot be completely screwed in place. This can cause the connection insecure, and long-term operation probably causes the potential safety hazard such as water pump loosening, abnormal sound even drop. 2. The hole position alignment is time-consuming, and the production efficiency is low, namely when the water pump and the water pump bracket are assembled and fixed, a certain operation time and precision are required for manually locating the positions of all the fixing holes. Especially in the case of mass production, repeated hole alignment operations can significantly reduce overall production efficiency. Disclosure of utility model Based on the technical problems that screw fastening is limited and hole site comparison is time-consuming when a water pump and a water pump support are fixed in the prior art, the water pump preassembling tool can preassemble the water pump and the water pump support together, through arranging the avoidance holes, interference between the fixing screws and an operation table in the screwing process is avoided, the screws can be completely fastened in place, through cooperation of the positioning columns and the protruding structures, the fixing holes of the water pump and the water pump support can be aligned in advance, the subsequent installation operation time is saved, and the production efficiency is improved. The utility model provides a water pump preassembling tool, which is used for preassembling a water pump and a water pump bracket and comprises the following components: an operation table; At least a set of location structure locates on the operation panel, include: The positioning columns are used for being matched with the mounting holes of the water pump bracket; The positions of the avoidance holes respectively correspond to the fixing holes of the water pump bracket, the fixing holes of the water pump and the fixing screws penetrating through the two to form avoidance spaces; A protrusion structure, a positioning surface is formed on the side surface of the protrusion structure, the positioning surface is configured to be in contact positioning with the side wall surface of the water pump, and the fixing holes are used for enabling the fixing holes of the water pump bracket to be aligned with the fixing holes of the water pump. In some embodiments, the raised structure has a side plate portion connected to the console and a top plate portion connected to the top of the side plate portion, the side of the top plate portion forming the locating surface. In some embodiments, the top plate portion is provided with a hollowed-out area. In some embodiments, the cross section of the top plate part is in a sector shape, the intrados of the top plate part forms the positioning surface, and the side plate part extends downwards along the outer arc edge of the top plate part.
