Abstract
An oil feeding pipe welding mould of a duplex hydraulic pump is mainly composed of a mould fixing plate, a support plate, bolts and nuts and is characterized in that eight holes are arranged on the mould fixing plate, hole size and hole distance of the holes are consistent with hole size and hole distance of holes on the duplex hydraulic pump, the support plate is welded on the mould fixing plate, and the bolts are fixed in the eight holes fixed on the mould fixing plate in welding mode. The oil feeding pipe welding mould has the advantages of being simple in structure, convenient to operate and capable of conducting quick welding.
Description
Technical field
The utility model relates to a kind of duplex hydraulic pump oil inlet pipe welding positioner.
Background technology
On present urban construction each side, autocrane has become requisite hoist tool.According to market survey, to lay at sewer pipe, building is built etc., and the ease of use of crane makes the people very clear.Present crane all is the hydraulic-driven of utilizing, and hydraulic torque is large, and safety coefficient is high, requires hydraulic system stable in crane work process, must not oil impregnate.Hydraulic pump is the power source of supply car body various piece hydraulic oil.The hydraulic pump oil inlet pipe can weld out smoothly, reaches instructions for use, the reliability of guarantee hydraulic pump fuel feeding, and for this reason, we have developed a kind of welding positioner of hydraulic pump oil inlet pipe, make things convenient for workman's rapid welding, also can reach instructions for use.
Summary of the invention
The purpose of this utility model is in order to overcome the problem of hydraulic pump oil inlet pipe post welding distortion, a kind of duplex hydraulic pump oil inlet pipe welding positioner to be provided.
The technical scheme that its technical problem that solves the utility model adopts is to implement like this: a kind of duplex hydraulic pump oil inlet pipe welding positioner, mainly formed by mold fixed head, support plate, bolt, nut, it is characterized in that: the mold fixed head is provided with eight holes, and the size in its hole, pitch-row are all consistent with size, the pitch-row in hole on the duplex gear pump; Support plate is welded on the mold fixed head, and bolt is fixed by welding in eight holes on the mold fixed head.
The utlity model has simple in structure, easy to operate, but the characteristics of rapid welding.
Description of drawings
Fig. 1 is structural front view of the present utility model;
Fig. 2 is structure top view of the present utility model.
Among the figure: 1. mold fixed head, 2. support plate, 3. bolt, 4. nut.
The specific embodiment
A kind of duplex hydraulic pump oil inlet pipe welding positioner, mainly formed by mold fixed head 1, support plate 2, bolt 3, nut 4, it is characterized in that: mold fixed head 1 is provided with eight holes, and the size in its hole, pitch-row are all consistent with size, the pitch-row in hole on the duplex gear pump; Support plate 2 is welded on the mold fixed head 1, and bolt 3 is fixed by welding in eight holes on the mold fixed head 1.
Duplex gear pump has two oil-ins, simultaneously oil-feed, and two hydraulic fluid port flanges of this oil inlet pipe namely will guarantee spacing, guarantee that again two faces are parallel.
During welding, four holes and bolt 3 corresponding placements with two oil-feed flanges, tighten with nut 4, the remaining parts correspondence is placed on the mold, support plate 2 is used for limiting the oil pipe position in the mold device, during welding that each junction spot welding is solid, after preliminary welding is finished, nut 4 is unclamped reinforcement of weld, polishing welding seams, the oil inlet pipe welding is finished.
The utlity model has simple in structure, easy to operate, but the characteristics of rapid welding.
