Description

Multipurpose automatic heating machine

Technical Field

The invention belongs to the technical field of heaters, and particularly relates to a multipurpose automatic heater.

Background

When a rotating shaft, a bearing, a chain wheel, a belt wheel, an iron core, a box body, a crankshaft connecting rod mechanism with a bearing and the like which are in interference fit or transition fit are assembled, a special press-fitting mold is originally adopted for pressure assembly on a press machine, but when the bearing with the crankshaft is assembled on an aluminum box body of a motorcycle engine, due to structural limitation, the special press-fitting mold is difficult to enable the pressure acting on the periphery of the bearing to be uniform, and the coaxiality of the bearings in the two box bodies after press-fitting cannot completely meet the design requirements. In order to improve the coaxiality, the inner diameter of a bearing chamber of the box body matched with the bearing and the outer diameter of an outer ring of the bearing can only be made into micro-clearance fit, and after the engine runs for a period of time, along with the rise of temperature, a larger clearance is generated between the inner wall of the bearing chamber of the box body and the outer ring of the bearing, the clearance can influence the positioning precision of the crankshaft bearing, and extra vibration and noise are brought to the assembled engine. If the bearing chamber of the box body is in interference fit with the outer diameter of the outer ring of the bearing, the bearing is forcibly pressed in, then the crankshaft bearing retainer matched with the inner diameter of the inner ring of the bearing is in clearance fit, and the inner diameter of the inner ring of the bearing and the crankshaft bearing retainer are abraded due to the rotary friction generated along with the alternate starting and stopping of the engine, so that the service life of the inner diameter of the inner ring of the bearing and the crankshaft bearing retainer and the use effect of the whole machine are reduced.

Later, a manual heating of the cabinet was used: the box body of the motorcycle engine is held by hand, a bearing chamber of the box body enters a high-frequency heating ring of heating equipment, and when the bearing chamber is heated until the bearing chamber expands to be capable of smoothly assembling a bearing with a crankshaft connecting rod mechanism, the bearing chamber is separated from the heating ring, is shifted to a workbench, and is firstly placed with a chain and then is assembled with the crankshaft connecting rod mechanism with the bearing.

Because the heated box body starts to shrink immediately after being separated from the heating source, the assembly time is short, the positioning is inaccurate, the expansion range of the bearing chamber of the box body and the uniformity around the bearing chamber are difficult to master, the action is slow, and the shrunk bearing chamber can firmly clamp the bearing in the crank connecting rod mechanism which is not in place and is difficult to separate. If the method that one hand grasps the upper end of the crankshaft in the crankshaft connecting rod mechanism and the other hand grasps the soft mallet to knock the box body is adopted, the crankshaft connecting rod mechanism is forcibly withdrawn from the bearing chamber of the box body, and then is heated and assembled again after being withdrawn, the bearing can generate great noise, the product quality of the whole machine is seriously influenced, only all parts are scrapped, and the heat jacket cannot be lost greatly. The heating temperature and uniformity can only be determined by experience, and the general new staff is difficult to adapt. And the required working time is long, the labor intensity is high, the working efficiency is low, the safety performance is poor, and the method is not suitable for mass production.
