压接机结构 Press frame 由油箱、动力机构、换向阀、卸压阀、泵油机构组成，泵油机构由油泵体、高、低压油出油孔、偏心轴、偏心轴承、从动齿轮和一对高压油泵以及一低压油泵构成，油泵体悬固于油箱盖上，高、低压油出油孔开设在油泵体上，与卸压阀油路连接，偏心轴呈纵向设置，上端枢置于油泵体中央，下端固设偏心轴承，从动齿轮固置在偏心轴顶部，与动力机构联结，高、低压油泵悬固在油泵体上，各具一与偏心轴承相触的作动件，高、低压油泵的泵腔分别与高、低压油出油孔相通。优点：将泵油机构与动力机构的连接为垂直连接，可充分利用空间而小化占地面积，有利于作业及运输；将高、低压油泵的泵油形式变为偏心轴承的作动形式，具有结构简单、零部件少而利于装配。 By tank, power establishment, reversing valve, pressure relief valve, pump oil, institutions, oil pump body by the oil hole, high and low pressure oil pump body, eccentric shaft, eccentric bearing, driven gear and a pair of high pressure oil pump, and a low pressure oil pump, oil pump body suspended solid in the cap, high and low pressure oil out of the oil hole opening on the pump body, connected to the oil pressure relief valve, eccentric shaft longitudinally Settings, the upper central pivot in the pump body, the bottom is set eccentric bearing, driven gear fixed on the top of the eccentric shaft, and the dynamic mechanism, high and low pressure oil pump on the suspended solid in the pump body, each a touch with eccentric bearing for moving parts, high and low pressure oil pump respectively with high and low pressure oil pump chamber of the oil hole is same. Advantages: connecting the pump oil mechanism with the power mechanism is the vertical connection, which can make full use of the space and the small size of the area, which is beneficial to the operation and transportation; The pump oil form of high and low pressure oil pump is changed into eccentric bearing, which has simple structure and little parts.
