A starter planetary shaft automatic press-fitting device

Abstract

The invention discloses an automatic press-fitting device of starter planetary shafts and belongs to the field of press-fitting devices. The automatic press-fitting device of the starter planetary shafts comprises a rack, a hydraulic rotary platform, a pin pressing component, a laser printing component and a bearing pressing component. Each station of the hydraulic rotary platform is provided witha planetary shaft clamping tool used for clamping the planetary shafts. The pin pressing component, the laser printing component and the bearing pressing component are installed at the correspondingstations of the hydraulic rotary platform. The pin pressing component comprises a hydraulic cylinder, a pin feeding mechanism, a pin positioning mechanism and a pin stabilizing mechanism and can complete the actions of pin taking, pin feeding, pin positioning, pin stabilizing and the like at the same time. The laser printing component is used for carrying out laser printing on the planetary shaftswhich are subjected to pin pressing. The bearing pressing component is used for pressing bearings for the planetary shafts. The automatic press-fitting device is mainly used for completing pin pressing, laser printing, bearing pressing and other working procedures on the planetary shafts at a time, the automation degree is high, the press-fitting speed and the precision are high, safe operation is easy, running is stable, and the reliability is high.

Description

technical field [0001] The invention relates to a press-fitting device, in particular to an automatic press-fitting device for a planetary shaft of a starter. Background technique [0002] The planetary shaft of the starter is a key component in the starting process of the vehicle engine, which has a large market demand and high quality requirements. After the planetary shaft is processed, it needs to press the pin, press the bearing and print the part number on the end face. After the press is completed, some technical parameters, such as the circular runout tolerance formed by several pins, the tensile force of each pin and the degree of deformation of the bearing All have strict technical specification requirements. At present, the press-fitting of the planetary shaft of the starter is mostly done manually, but at least 4 operators are required to complete the press-fitting of a planetary shaft. The production cost of the enterprise reduces the competitiveness of the en...
