Description
Technical Field
The utility model relates to an excavator counterweight plate machining tool, excavator counterweight plate welding positioning fixture specifically says so.
Background
The excavator counterweight plate mainly comprises a flat-plate-shaped base, and a circular tube and a bending plate are arranged on the base. The circular tube and the bending plate of the excavator counterweight plate are welded on the base.
At present, the welding process of a circular tube and a bending plate of a counterweight plate of an excavator is that a worker firstly measures corresponding positions on a base by using a measuring tape and a set square, marks the corresponding positions, and then welds the circular tube and the bending plate on the base through the marks. The welding mode needs to measure the position first, and the working efficiency is low. Moreover, the precision of manual measurement is lower, and the defective rate is higher.
SUMMERY OF THE UTILITY MODEL
The to-be-solved technical problem of the utility model is to provide an excavator counterweight plate welding is with positioning fixture, the work efficiency who adopts this anchor clamps is higher, and welding precision is higher, and the defective rate is lower.
In order to solve the problems, the following technical scheme is provided:
the utility model discloses an excavator is positioning fixture for counterweight plate welding's characteristics include with the rectangular plate of digging quick-witted counterweight plate's base looks adaptation, a set of edge that links to each other of rectangular plate all has the spacing strip. The rectangular plate is provided with a round hole for positioning a round pipe of the excavator counterweight plate, and the hole wall of the round hole is uniformly provided with first notches along the circumferential direction of the round hole. One end of the rectangular plate is provided with an opening for positioning a bending plate of the excavator counterweight plate, and the bottom of the opening is provided with a second notch.
Spacing is 7 fonts, and the lateral part of spacing is towards the rectangular plate, and the equal welded fastening of lateral part of spacing is on the last face of rectangular plate, and the portion of erectting of spacing is in the same place rather than the rectangular plate that corresponds on one side laminating.
The number of the limiting strips is four, and the limiting strips are distributed on a group of connected edges of the rectangular plate in pairs.
The first gap has four.
By adopting the scheme, the method has the following advantages:
because the utility model discloses an excavator is all there is the spacing strip on the rectangular plate of counterweight plate welding positioning fixture's a set of edge that links to each other of rectangular plate, has the round hole on the rectangular plate, has first breach along its circumference equipartition on the pore wall of round hole, and there is the opening rectangular plate one end, and there is the second breach open-ended bottom. When the limiting strip is used, the rectangular plate is placed on the base of the excavator counterweight plate, so that the limiting strip is abutted against the base of the excavator counterweight plate; then, placing a circular tube of the excavator counterweight plate into the circular hole, performing spot welding at the first notch, and fixing the circular tube on the base; then, placing the bending plate into the opening, and fixing the bending plate on the base by spot welding at the second notch; and finally, taking down the rectangular plate, and fully welding the circular tube and the bending plate on the base. The positioning fixture can be used for directly positioning the circular tube and the bending plate, so that manual measurement is not needed, the welding process is greatly simplified, and the working efficiency is improved. Moreover, the positioning precision of the positioning clamp is higher, and the reject ratio is greatly reduced.
Drawings
Fig. 1 is a schematic structural view of the positioning jig for welding the counterweight plate of the excavator of the present invention;
fig. 2 is a use state diagram of the positioning jig for welding the excavator counterweight plate of the present invention.
Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings.
As shown in figure 1 and figure 2, the utility model discloses an excavator is positioning fixture for counterweight plate welding's characteristics are including the rectangular plate 1 with the base looks adaptation of digging machine counterweight plate, all have spacing 3 on a set of continuous edge of rectangular plate 1. The rectangular plate 1 is provided with a round hole 4 for positioning a round pipe of the excavator counterweight plate, and the hole wall of the round hole 4 is uniformly provided with first notches 2 along the circumferential direction. One end of the rectangular plate 1 is provided with an opening 5 for positioning a bending plate of the excavator counterweight plate, and the bottom of the opening 5 is provided with a second notch 6.
The number of the limiting strips 3 is four, and the four limiting strips are distributed on a group of connected edges of the rectangular plate 1 in pairs.
The first notches 2 are four in number.
When the limiting device is used, the rectangular plate 1 is placed on the base 7 of the excavator counterweight plate, so that the limiting strip 3 is abutted against the base 7 of the excavator counterweight plate; then, placing the circular tube 8 of the excavator counterweight plate into the circular hole 4, performing spot welding at the first notch 2, and fixing the circular tube 8 on the base 7; then, the bending plate 9 is placed in the opening 5, spot-welded at the second notch 6, and the bending plate 9 is fixed to the base 7; and finally, taking down the rectangular plate 1, and fully welding the circular tube 8 and the bending plate 9 on the base 7.
