Abstract
The utility model discloses a hydraulic press driving device comprising a hydraulic motor, wherein a shaft coupling is respectively arranged at two ends of the hydraulic motor; a commutator is further arranged on the shaft coupling; a gear is disposed at the lower part of the commutator; the gear is in shaft connection with the commutator; and the shaft coupling is in shaft connection with the hydraulic motor. A rack is connected on the gear in an engaged manner, and the lateral surface of the rack is perpendicular to the commutator. The hydraulic press driving device is simple in structure and convenient in use; and the lateral surface of the rack on the hydraulic press is upward, so that sundries on a frame of the hydraulic press cannot clamp the rack even if the sundries fall down, thereby facilitating the stable operation of the hydraulic press.
Description
Technical field:
The utility model relates to the technical field of hydraulic press used in the welded tube unit, particularly a kind of hydraulic press drive unit.
Background technique:
Hydrostatic testing machine is called for short hydraulic press, and hydraulic press is a constituent element important in the welded tube unit, is mainly used in to steel duct water-filling to be measured supercharging, is used to detect the intensity and the compactness of steel pipe.The hydraulic press drive unit is even more important as the power section of hydraulic press.As shown in Figure 1, be the structural representation of hydraulic press drive unit of the prior art: the frame bottom of hydraulic press is provided with drive unit, and drive unit comprises oil hydraulic motor 3 and transmission shaft 6; One end axle of oil hydraulic motor 3 is connected with driving gear 4, and the middle part of transmission shaft 6 is provided with driven gear 5, is connected with a joggle between driving gear 4 and the driven gear 5; The two ends of transmission shaft 6 are provided with bearing 2 and driving gear 1; The tooth bar 7 that has been connected with a joggle on the driving gear 1, during work, oil hydraulic motor 3 drives driving gears 4 and rotates; Driving gear 4 and driven gear 5 engagements; Driven gear 5 drives transmission shaft 6 and driving gear 1, and driving gear 1 drives the hydraulic press frame and travels forward at tooth bar 7 top offsets.The tooth bar 7 of this structure, the plane of tooth bar 7 makes progress, and the foreign material on the hydraulic press frame like nut, after welding rod or other impurity drop, very easily are stuck in the hole of tooth bar 7.In case tooth bar 7 is stuck, then cause the failure of the hydrostatic test, and, very easily cause the damage of tooth bar 7 or driving gear 1, need stop production to overhaul, loss is big.
In view of this technical problem, it is a kind of simple in structure, easy to use to press for appearance, and tooth bar upwards even the foreign material on the hydraulic press frame drop, can not blocked in the side of the tooth bar of hydraulic press yet, can make a kind of hydraulic press drive unit of hydraulic press smooth working.
Summary of the invention:
The purpose of the utility model is to overcome the shortcoming that exists in the existing technology, provides a kind of simple in structure, easy to use; The side of the tooth bar of hydraulic press upwards; Even the foreign material on the hydraulic press frame drop, can not block tooth bar yet, can make a kind of hydraulic press drive unit of hydraulic press smooth working.
To achieve these goals, the utility model provides a kind of hydraulic press drive unit, comprises oil hydraulic motor; Wherein, The two ends of said oil hydraulic motor are provided with coupling, further are provided with commutator on the said coupling, and the bottom of said commutator is provided with gear; Axle is connected between said gear and the said commutator, spool is connected between said coupling and the said oil hydraulic motor.
The tooth bar that has been connected with a joggle on the said gear, the lateral vertical of said tooth bar is in said commutator.
The outstanding advantage of the utility model is: simple in structure, easy to use, tooth bar upwards even the foreign material on the hydraulic press frame drop, can not blocked in the side of the tooth bar of hydraulic press yet, can make the hydraulic press smooth working.Specific as follows:
The oil hydraulic motor transmission coupling motion of the utility model; Coupling is changed direction through commutator again; Tooth bar on the gear on the commutator is holded up; The lateral vertical that is tooth bar is in commutator, and the hole on the tooth bar promptly can not blocked by the foreign material that drop in the top, can make the working state of hydraulic press held stationary.
