Description

Hard pipe assembly tool of driving motor oil cooler water nozzle Technical Field The invention relates to the technical field of assembly tools, in particular to a driving motor oil cooler water nozzle hard tube assembly tool. Background Along with the increasing rotation speed and the increasing power density of the motor of the new energy automobile, the motor generates a large amount of heat, so that new challenges are brought to heat dissipation of the motor, most of motors in the prior art adopt a water cooling technology, but the water cooling technology belongs to indirect cooling, and the motor with high rotation speed and large torque cannot be completely met, so that the current new energy automobile starts to use an oil cooling motor. The oil cooler is an extremely important part in an oil cooling motor cooling system, the oil cooler is used for providing circulating cooling liquid for a driving motor, the cooling liquid takes away heat in the driving motor, a hard pipe water nozzle is arranged on a shell of the oil cooler, the hard pipe is connected with a cooling pipe of the whole automobile, and when the oil cooler is assembled, the hard pipe is required to be inserted into the water nozzle according to a designed state, but in the actual assembly process, due to lack of a special positioning tool, operators can only visually operate through experience, the hard pipe is knocked into the water nozzle of the oil cooler through a simple tool, and the oil pipe angle can deviate from the designed state by the assembly mode, and even the water nozzle is deformed due to deviation of a force application direction during knocking. Disclosure of Invention In order to solve the problems, the invention provides a driving motor oil cooler water nozzle hard tube assembling tool. The technical scheme for solving the technical problems is as follows: The utility model provides a driving motor oil cooler water nozzle hard tube assembly tool, includes first part, second part, first part and second part clearance fit, first part is hollow cylinder, is equipped with a plurality of scale on the axial terminal surface of first part, the axial lead centering of scale and hard tube, the other end of first part is equipped with and prolongs the rising base, is equipped with first breach on the radial global of first part, the second part passes first part, and second part and first part clearance fit, and the axial terminal surface of second part is equipped with centering mark, still is equipped with the second breach on the radial global of second part, the scale cooperation on centering mark and the first part axial terminal surface, second breach and hard tube clearance fit. Further, one end of the second part is exposed outside the first part, and the other end of the second part is located in the first part. Further, the scales on the axial end face of the first component are even number equal division scales.
