Problems solved by technology
[0003] 1) Workers in the workshop use manual installation when hot-loading, and they may be burned if they are not careful, so there are potential safety hazards
[0004] 2) Manual installation is slow due to the need for centering, and the press-fitting process takes about 20 seconds. At this time, the bushing is easy to cool down, and the expansion of the bushing is not enough, resulting in quality defects that the press-fitting is not in place, resulting in rework and scrap rate High; when the bushing is reworked, it is easy to cause damage to the anti-roll torsion bar body, resulting in the scrapping of the anti-roll torsion bar

The invention discloses an antiroll torsion bar sleeve hot installation machine. The antiroll torsion bar sleeve hot installation machine comprises a machine frame, wherein a positioning mechanism used for fixing a rod piece and a pressure installation mechanism used for installing a sleeve on the terminal of the rod piece are respectively installed at two ends of the machine frame, the pressure installation mechanism comprises a pressure device fixedly installed on the machine frame and a pressure installation cylinder fixedly installed at a telescopic end of the pressure device, one end of the pressure installation cylinder is fixedly connected with the pressure device, a centering rod used for installing a cylinder part is arranged at the other end of the pressure installation cylinderin penetration mode, the centering rod is inserted in a pressure cylinder in sliding mode, the centering rod and the pressure cylinder are connected through an elastic mechanism, and a heater used forheating the cylinder part is arranged on the lateral of the pressure installation mechanism. By centering the cylinder part and the rod piece through the centering rod, deviation is reduced, centering efficiency is high, and installation is facilitated, and by heating and expanding the cylinder part through the heater, the cylinder part can be conveniently installed on the rod piece, directly contact of a worker is avoided, accidents of fire burning, scalding and the like are avoided, and production safety is improved.
Description
technical field [0001] The invention relates to the field of sleeve preheating installation equipment, in particular to an anti-rolling torsion bar sleeve thermal installation machine. Background technique [0002] When the EMU anti-roll torsion bar is overhauled, it is necessary to press-fit the bushing to the end of the anti-roll torsion bar shaft. The shaft and the bushing are interference fit. The original bushing is installed manually after being heated to 500°C. This method is relatively simple, but there are the following problems: [0003] 1) Workers in the workshop use manual installation when hot-loading, and they may be burned if they are not careful, so there are potential safety hazards. [0004] 2) Due to the need for centering, the efficiency of manual installation is slow, and the press-fitting process takes about 20 seconds. At this time, the bushing is easy to cool down, and the expansion of the bushing is not enough, resulting in quality defects that the ...
