Multi-station pinion shaft pressing assembling machine

Abstract

The invention discloses a multi-station pinion shaft pressing assembling machine which comprises a stand, a steel-shaft feeding device, a pinion feeding device, a pre-positioning clamp, a shaft pressing assembling device, a transmission mechanism and a control system. The transmission mechanism is arranged on the stand and comprises a motor, a main transmission wheel, an auxiliary transmission wheel and a transmission chain or a transmission belt; the axes of all the transmission wheels and the motor are arranged horizontally; the shaft of the main transmission wheel is connected with the shaft of the motor; the pre-positioning clamp is fixedly connected with the transmission chain or the transmission belt; the motor is controlled by the control system to drive the transmission chain or the transmission belt to transmit intermittently in a positioning way; a shaft dropping station, a pinion pushing station and a shaft pressing assembling station are arranged on the stand along the transmission direction of the transmission chain or the transmission belt; and the steel-shaft feeding device, the pinion feeding device and the shaft pressing assembling device are arranged on the shaft dropping station, the pinion pushing station and the shaft pressing assembling station correspondingly. By adoption of the multi-station pinion shaft pressing assembling machine, the efficiency of assembling the pinion and the steel shaft assembly can be effectively improved, the interference fit of the pinion and the steel shaft can be realized reliably, the discharging can be convenient, the manpower can be saved, and the shaft pressing assembling of the pinion with different types and the steel shaft can be realized through adjustment or reconstruction.

Description

technical field [0001] The invention relates to the field of processing and assembling of small parts, in particular to an automatic final shaft assembly equipment for assembling pinion gears and steel shafts required by toy reducers and the like. Background technique [0002] At present, when domestic toy manufacturers assemble gear reducers commonly used in toys, most of them use manual or semi-automatic machinery for assembly, which has disadvantages such as low efficiency, high scrap rate, and low safety; the existing automatic finale assembly machinery Most of them are single-station assembly methods, and their main disadvantages are: first, it cannot improve efficiency, because all assembly actions are carried out at one station, and the space for efficiency improvement is limited; second, it can only adapt to a single type of steel shaft and plastic small Gear assembly, and there are many kinds of toy reducers, and the combination of steel shaft and plastic pinion is ...

[0004] The paper "Design and Realization of Watch Wheel Automatic Assembly Machine" published in "Machinery Manufacturing and Automation" [Chen Rufu et al., 2009, No. 1: 144-147] A steel shaft and plastic gear used in the watch industry Automatic assembly machine: adopts disc type multi-station working mode, decomposes the automatic assembly work of steel shaft and gear into 8 stations for execution, that is, shaft blanking station, shaft inspection station, gear blanking station, Gear detection station, clamping assembly station, discharge station, discharge detection station, discharge secondary detection station; the automatic feeding of steel shafts and plastic gears adopts electromagnetic circular vibration hoppers, steel shafts Both plastic gears and plastic gears use free fall to enter the station; however, this structure has two disadvantages. First, the assembled components are directly sucked out by a vacuum pump, which limits the speed of machine assembly. At the same time It also increases the cost of the machine. Second, the designer did not consider the reconfigurable requirements of the machine when designing the machine. The machine can only be assembled for a specific steel shaft and gear, which limits the scope of use of the machine.
