It plays a very important role in the logistics system and is the main force in material handling equipment. Internal combustion forklift accounts for a large proportion of the entire market. Its core parts mainly include engines, gearboxes, drive axles, etc. Among them, the component engine has very high coaxiality requirements, and the coaxiality requirement between the clutch housing and the engine is ≤0.02mm. In order to ensure product quality and assembly accuracy, a horizontal drilling machine is used for matching drilling processing. However, different engines have different positions and sizes of matching holes, and the horizontal drilling machine only has X-axis and Y-axis, and does not have Z-axis processing function. Therefore, different auxiliary devices need to be designed for positioning for different engines. There are many types of engines, with more than 10 types. As a result, when assembling different engines, it is necessary to switch the auxiliary devices that match them for matching drilling. The switching frequency is high and the production efficiency is low.

[0021] In order to enable those skilled in the art to better understand the technical solutions in this application, the technical solutions in the embodiments of this application will be clearly and completely described below. Obviously, the described embodiments are only part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.
[0022] like Figure 1-3 As shown, the embodiment of the utility model provides a coaxiality calibration auxiliary device for a forklift engine, comprising a base 1 and a positioning mechanism 2, a lifting mechanism 3 and a guide mechanism 7 arranged on the base 1. The positioning mechanism 2 and the lifting mechanism 3 are arranged on opposite sides of the base 1. The positioning mechanism 2 is provided with a positioning pin 5 for cooperating with a mounting seat of the engine 4. The outer diameter of the positioning pin 5 is smaller than the inner diameter of the mounting hole of the mounting seat of the engine 4, and the tolerance between the two is between 0 and 0.02 mm, so as to ensure that the engine 4 can be stably placed on the positioning mechanism 2, avoid the movement of the engine 4 during the drilling process, and ensure the assembly accuracy requirements. The lifting mechanism 3 is provided with a positioning pin 5 for cooperating with the engine 4. The motor 4 is provided with a lifting bracket 6 whose height matches that of the gearbox drive shaft mounting hole in the clutch housing. The guide mechanism 7 is arranged in the middle of the base 1. A roller 71 is arranged at the lower part of the guide mechanism 7. The roller 71 is arranged in a channel steel guide rail 72 arranged therewith and slides along the channel steel guide rail 72 to achieve guidance. The structure of the guide mechanism 7 can be any structure in the prior art that can achieve the guiding function. The guide mechanism 7 is arranged to improve the transfer efficiency. The existence of the guide mechanism 7 can prevent the transfer route of the coaxiality calibration auxiliary device of the forklift engine of this embodiment from being offset, and can be quickly transferred to the next process for operation. A fixable universal wheel 8 is arranged at the lower part of the base 1.
[0023] In this embodiment, the lifting mechanism 3 includes a lifting rod 31, and the lifting bracket 6 is arranged at the top of the lifting rod 31. Due to different models of engines 4, the heights of the mounting holes of the engines 4 from the ground are different. In order to meet the assembly process requirements of various engines 4, the lifting rod 31 is a screw structure, and an operating part 32 is provided on the lifting rod 31. The operating part 32 is used to facilitate the adjustment of the extension height of the lifting rod 31. The operator adjusts the lifting mechanism 3 through the operating part according to the model of the engine 4 to achieve up and down height adjustment.
[0024] In this embodiment, the positioning mechanism 2 includes a leg 1 21 and a leg 22. The heights of the leg 1 21 and the leg 2 22 are designed according to ergonomic requirements, and the distance between the leg 1 21 and the leg 2 22 is designed according to the mounting base of the engine 4. The structure and size of the leg 1 21 and the leg 2 22 are the same. Positioning pins 5 are provided on the leg 1 21 and the leg 2 22, and a reinforcement member 23 is provided between the leg 1 21 and the leg 2 22 to ensure that the structural stability of the entire positioning mechanism 2 is high.
[0025] In this embodiment, after the clutch housing is installed on the engine 4, the coaxiality calibration auxiliary device of the forklift engine of the present application is pushed to the corresponding work station. After adjustment, a horizontal drilling machine is used to start trial drilling, and then the lifting mechanism is adjusted according to the height of the drill. After the gearbox drive shaft mounting hole in the clutch housing is coaxial with the drill, drilling is started. After drilling and inspection, it is transferred to the next process through the universal wheel 8.
