Abstract

The utility model discloses an excavator motor support installing and welding locating device which comprises a work table, an inner die, clamping devices, a base locating device and a pressing plate, the inner die, the clamping devices and the base locating device are all fixedly connected to the work table through bolts, the base locating device is arranged on one side of the periphery of the inner die, the other three sides of the periphery of the inner die are provided with a plurality of clamping devices, and the pressing plate is arranged on the inner die. The inner die is replaceable so as to be adaptive to installing and welding of motor supports of different specifications. Through the profile modeling method, guide boards in irregular shapes can be shaped, the accuracy requirement of the guard boards is lowered, the structure is simple and compact, design is scientific and reasonable, operation is convenient, welding accuracy is high, and welding efficiency is high.

Description

Excavator motor bracket assembly welding positioner
Technical field
The utility model belongs to the motor bracket welding technology field, is specifically related to excavator motor bracket assembly welding positioner.
Background technology
Excavator is to excavate higher or lower than the material that holds machine side with scraper bowl, and the haulage vehicle or unload the earthmoving machinery to rickyard of packing into.Motor is the device of excavator dynamical system most critical, generally is arranged on motor bracket, and the quality of motor bracket quality can directly affect stability and the mechanical efficiency of excavator dynamical system.
The excavator motor bracket generally is comprised of backplate, fixed head, base etc., and by 30mm, thick manganese plate processes these parts usually, and machine-shaping is very difficult.Particularly backplate needs bending roll machine to be rolled into the arc of more than half circle, at the arc two ends also with straight flange, fixed head and base are very high to the requirement of size and perpendicularity, are difficult to be worked into accurate size, and these have brought difficulty all to the assembly welding of backplate, fixed head, base.Also do not have at present to fit together the motor bracket each several part is fastening, pinpoint device, for the assembly welding of motor bracket, causes the assembly welding precision of motor bracket low, and efficiency is low.
Summary of the invention
The above-mentioned defect existed in order to overcome the prior art field, the purpose of this utility model is, provides a kind of and can carry out shaping, guarantees assembly welding precision, efficiency, excavator motor bracket assembly welding positioner simple in structure.
The excavator motor bracket assembly welding positioner that the utility model provides, it comprises workbench, internal mold, clamping device, base positioner and pressing plate, described internal mold, clamping device and base positioner all are bolted to connection on workbench, one side of described internal mold periphery arranges the base positioner, other three sides some clamping devices that distribute, described pressing plate is arranged at above internal mold; The side spiral shell that described base positioner is relative with internal mold is connected and is connected to locating dowel and two and is symmetrical cushion block, and described locating dowel is arranged on the position near left side or right side cushion block; On described internal mold, in-plane has a screwed hole, described pressing plate center have one with circular hole that on internal mold, in-plane screwed hole diameter is identical; It also comprises double-screw bolt, and described double-screw bolt one end is fixedly connected with internal mold by in-plane screwed hole on internal mold, and the other end is through the circular hole of pressing plate center, by nut check.
The excavator motor bracket assembly welding positioner that the utility model provides, its beneficial effect is, internal mold is replaceable, thereby adapts to the assembly welding of the motor bracket of different size; Adopt the way of pattern, can carry out shaping to erose backplate, reduced the requirement to its precision; Simple in structure, compact, design science is reasonable, easy to operate, welding precision is high, welding efficiency is high.
The accompanying drawing explanation
Fig. 1 is the front view of an embodiment of the utility model;
Fig. 2 is the top view of Fig. 1.
In figure, mark:
1. workbench; 2. internal mold; 3. clamping device; 4. base positioner; 5. pressing plate; 6. locating dowel; 7. cushion block; 8. double-screw bolt; 9. nut.
The specific embodiment
With reference to the accompanying drawings, in conjunction with an embodiment, the excavator motor bracket assembly welding positioner that the utility model is provided is described in detail.
Embodiment
With reference to Fig. 1-Fig. 2, the excavator motor bracket assembly welding positioner of the present embodiment, it comprises workbench 1, internal mold 2, clamping device 3, base positioner 4 and pressing plate 5, described internal mold 2, clamping device 3 and base positioner 4 all are bolted to connection on workbench 1, one side of described internal mold 2 peripheries arranges base positioner 4,5 clamping devices 3 of other three sides distributions, described pressing plate 5 is arranged at above internal mold 2; The side spiral shell that described base positioner 4 is relative with internal mold 2 is connected and is connected to locating dowel 6 and two and is symmetrical cushion block 7, and described locating dowel 6 is arranged on the position near left side or right side cushion block 7; On described internal mold 2, in-plane has a screwed hole, described pressing plate 5 centers have one with circular hole that on internal mold 2, in-plane screwed hole diameter is identical; It also comprises double-screw bolt 8, and described double-screw bolt 8 one ends are fixedly connected with internal mold 2 by in-plane screwed hole on internal mold 2, and the other end is through the circular hole of pressing plate 5 centers, by nut 9 lockings.
Before carrying out assembly welding, at first select suitable internal mold 2 to be arranged on workbench 1, then the base of motor bracket is vertically stood up, its bottom surface abuts against on the cushion block 7 on base positioner 4, and straight flange abuts against on locating dowel 6; Again the fixed head of motor bracket is placed on internal mold 2 on plane, pushes down with pressing plate 5, by nut 9 lockings; Then the backplate of motor bracket is enclosed to the side that leans against internal mold 2, by 5 clamping devices 3, backplate only is attached on internal mold 2, is finally welded, by all parts assembly welding of motor bracket together, after having welded, unclamp clamping device 3 and take out motor bracket and get final product.
