Abstract
The invention provides a novel welding hopper rod comprising a box-shaped body. The box-shaped body comprises a left side plate, a right side plate, an upper cover plate, a bottom plate and a back cover plate, wherein the upper cover plate, the bottom plate and the back cover plate a cavity in a surrounding way, the left side plate and the right side plate are tightly attached to the upper cover plate, the bottom plate and the back cover plate, and the outer edges of the left side plate and the right side plate cover the cavity formed by the upper cover plate, the bottom plate and the back cover plate in a surrounding way. The assembling and welding time of the hopper rod is greatly shortened when the hopper rod is processed, the influence of an assembling gap on the welding quality of the hopper rod is furthest eliminated, and the hopper rod has the advantages of graceful and attractive appearance and smooth and natural line shape.
Description
Technical field
The present invention relates to a kind of welding dipper, the novel welding dipper that especially a kind of excavator uses.
Background technology
Present existing excavator boom, cover plate encases the mode of side plate about adopting mostly, and this method has higher requirement to the blanking and the bending precision of sheet material.In case error appears in any one operation of blanking and bending, will cause dipper when welding occur organizing to or group to the problem of excesssive gap.When error appearred in the circular arc place blanking of side plate, it is big that the radius of circular arc becomes, group to the time herein gap just be difficult to adjust, solution is that the bending of row secondary is put in recruitment usually.But still can occur as the blanking arc size diminish, situation such as the bending size of upper cover plate circular arc is less than normal or bigger than normal, so this is the most troubling place in the right manufacturing process of dipper group.Though a lot of producers have formulated the strict process standard, have also taked remedial measure for this reason afterwards, general effect still can not be satisfactory.If to the dipper welding, particularly robot welding can cause the inhomogeneous of each position intensity of welding point in the circular arc group to locating to produce weld defect, in use various problems can occur under the uneven situation in gap.
Summary of the invention
For overcoming known excavator boom group to the difficult technological deficiency of adjusting in gap, reduce the welding job amount simultaneously, the invention provides a kind of can the elimination group to the welding dipper of gap to the influence of dipper welding quality, be beneficial to the realization rapid welding, improved welding efficiency.
The technical scheme that technical solution problem of the present invention is adopted is:
A kind of novel welding dipper, comprise a box body, described box body comprises left plate, right plate, upper cover plate, base plate and back shroud, wherein, described upper cover plate, base plate and back shroud surround a cavity, and described left plate and right plate and described upper cover plate, base plate and back shroud fit tightly and outer rim was covered the cavity that described upper cover plate, base plate and back shroud surround.
Above-mentioned novel welding dipper, wherein, also comprise bucket cylinder seat and bucket arm cylinder connecting rod base, the ledge that described bucket cylinder seat and bucket arm cylinder connecting rod base covered the cavity that described upper cover plate, base plate and back shroud surround by described left plate and described right plate outer rim constitutes, between described bucket cylinder seat and the bucket arm cylinder connecting rod base with arc transition.
Above-mentioned novel welding dipper also comprises scraper bowl pin shaft hole and swing arm pin shaft hole, and wherein, on described left plate and the right plate, the pin-and-hole position of described scraper bowl pin shaft hole, swing arm pin shaft hole, bucket cylinder seat and bucket arm cylinder connecting rod base is provided with stiffener.
Above-mentioned novel welding dipper, wherein, the material of described left plate and right plate is a structural carbon steel.
Above-mentioned novel welding dipper, wherein, described structural carbon steel is the Q345B steel.
The invention has the beneficial effects as follows:
Dipper add man-hour group to and shorten greatly weld interval, eliminated on the amplitude peak group to the gap to the influence of dipper welding quality, elegant shape is attractive in appearance, linear smooth nature.
Description of drawings
Fig. 1 is the structure diagram of the novel welding dipper of the present invention;
Fig. 2 is the left side view of Fig. 1.
The specific embodiment
The invention will be further described below in conjunction with the drawings and specific embodiments, but not as qualification of the present invention.
As shown in Figure 1, the novel welding dipper of the present invention comprises a box body, this box body comprises left plate 1, right plate 2, upper cover plate 3, base plate and back shroud, wherein, upper cover plate 3, base plate and back shroud surround a cavity, and left plate 1 and right plate 2 outer rims were covered the cavity that upper cover plate 3, base plate and back shroud surround.The ledge that bucket cylinder seat 4 and bucket arm cylinder connecting rod base 5 covered the cavity that upper cover plate 3, base plate and back shroud surround by left plate 1 and right plate 2 outer rims constitutes, with left plate 1 is the whole blanking of back otic placode that example constitutes the upper ear plate and the formation bucket arm cylinder connecting rod base 5 of bucket cylinder seat 4, mode fluid-tight engagement by arc transition together each other, and become one with left plate 1, right plate 2, make bulk strength be guaranteed.The group of the novel welding dipper of the present invention is the width dimensions of cover plate to the cutting stock precision of the required assurance of mode, for plate cutting and programming, straight line is simple more accurately than circular arc, and the bending precision of back shroud and base plate can be ignored fully, because left plate 1 and right plate 2 just encase it, no longer to mode, overlap one by one as traditional group, otic placode is direct stress point, so the welding job amount at otic placode place is very big, add limited space, it is the bottleneck that the dipper welding efficiency promotes always, because left plate 1 and right plate 2 are whole blankings, saved upper ear plate that constitutes bucket cylinder seat 4 and the welding job amount that constitutes the back otic placode of bucket arm cylinder connecting rod base 5, so just shortening group greatly is to reaching weld interval.Adopt robot welding machine and positioner operation simultaneously during welding, can realize rapid welding, can adopt intermittent weld at welding limited space position, and manually weld afterwards.
As shown in Figure 2, above-mentioned novel welding dipper also comprises scraper bowl pin shaft hole 6 and swing arm pin shaft hole 7, the pin-and-hole position of the scraper bowl pin shaft hole 6 on the left plate 1 is provided with stiffener 81, the pin-and-hole position of swing arm pin shaft hole 7 is provided with stiffener 82, the pin-and-hole position of bucket cylinder seat 4 and bucket arm cylinder connecting rod base 5 is provided with stiffener 83, relevant position on the right plate 2 also is provided with stiffener, the connected mode of stiffener and left plate 1 and right plate 2 is welding, also available robot welding machine is finished welding, though the novel welding dipper of the present invention needs the repair welding stiffener, its welding difficulty reduces greatly than original otic placode place welding.The material of left plate 1 and right plate 2 is a structural carbon steel, if select high slightly sheet material of intensity such as Q345B for use, does not just need to add the weldering stiffener fully.
In sum, having eliminated group on the novel welding dipper of the present invention amplitude peak influences the dipper welding quality the gap, be beneficial to the realization rapid welding, and good looking appearance is generous.
The above is only for preferred embodiment of the present invention, is not so limits claim of the present invention, so the equivalent structure that all utilizations manual of the present invention and diagramatic content have been done changes, all is included in protection scope of the present invention.
