Specific embodiment
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete
Site preparation description, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.It is based on
Embodiment in the present invention, it is obtained by those of ordinary skill in the art without making creative efforts every other
Embodiment shall fall within the protection scope of the present invention.
In order to make those skilled in the art more fully understand the present invention program, with reference to the accompanying drawing and it is embodied
The present invention is described in further detail for mode.
A kind of assembly positioning device of cotton picker cotton-picker head rack provided by the embodiment of the present invention, such as Figure of description 1
To shown in attached drawing 4, including locating platform 1, pressing plate, positioning angle square 50, tack welding seaming element 5 and locating rod soldering component 30.
When assembling the upper box and lower box of cotton picker cotton-picker head rack, positioning support is carried out using locating platform 1,
The upper cover plate and lower box of upper box are alternatively placed on locating platform 1.When needing to assemble upper box, then using pressing plate and
Tack welding seaming element 5 positions upper box, when needing to assemble lower box, then utilizes positioning angle square 50 and locating rod soldering
Component 30 positions lower box；That is, pressing plate, tack welding seaming element 5, utilizing positioning angle square 50 and locating rod soldering component
30 4 can be detachably connected relative to locating platform 1, specifically, the modes such as bolt can be used and realize detachably connect
It connects.
When positioning upper box, upper cover plate is placed in locating platform 1 first, pressing plate is then placed in the upper of upper cover plate
Technique through-hole is often arranged in surface, upper cover plate, technique through-hole can be worn by components such as screws, so that upper cover plate is anchored on
Locating platform 1 realizes the positioning operation to locating platform 1.
Tack welding seaming element 5 includes locating shaft 51 and positioning sleeve 52, and locating shaft 51 extends along the vertical direction, and 52 sets of positioning sleeve
Set on locating shaft 51, positioning sleeve 52 is equipped with briquetting 4, and briquetting 4 is set to the upper surface of positioning sleeve 52, and briquetting 4 is along remotely located set 52
Radially extend, as shown in Figure of description 1 and attached drawing 2.
The top of locating shaft 51 is additionally provided with top positioning sleeve, when the upper cover plate of upper box is fixed on locating platform by pressing plate
After 1, positioned by support plate of the tack welding seaming element 5 to upper box.
Specifically, support plate has through-hole, and the through-hole of support plate sets locating shaft 51 from trapping by upper, the outer rim of positioning sleeve 52
It fits with the through-hole wall of support plate namely the clear size of opening of the size of the outer rim of positioning sleeve 52 and support plate is very nearly the same,
Be conducive to be promoted the positioning accuracy to support plate, and since support plate has a bending edges extended downwardly, bending edges and positioned
The upper cover plate of completion offsets, and support plate and upper cover plate relative position are fixed, and ensures support plate under the action of positioning sleeve 52
Position is reliable；Then the upper surface of briquetting 4 and through-hole is in contact namely briquetting 4 compresses the upper surface of support plate, it is ensured that support plate
Position in the vertical direction；In other words, positioning sleeve 52 positions the horizontal position of support plate, and briquetting 4 can be to branch
The vertical position of fagging is positioned.Certainly, briquetting 4 can be realized by components such as bolts relative to positioning sleeve 52 and detachably be connected
It connects.
After the positioning of the position of support plate and upper cover plate, the middle partition of upper box is placed at the positioning sleeve of top,
Namely middle partition is located at the top of both support plate and upper cover plate, support plate is located at the top of upper cover plate；Similar to the abovely, in
Partition has via hole, and the via hole inner wall of the outer rim of top positioning sleeve and middle partition fits, the physical dimension of top positioning sleeve and
The via size of partition is very nearly the same, so that the accurate positioning of middle partition, can be realized middle partition relative to locating platform 1 in this way
Position it is reliable, so far, upper cover plate, support plate and middle partition are successively determined by pressing plate, positioning sleeve 52 and briquetting 4, top positioning sleeve
Position, and since pressing plate, positioning sleeve 52 and briquetting 4, top positioning sleeve are fixed both with respect to the position of locating platform 1, thus upper cover
Plate, support plate and middle partition three are reliable relative to 1 position of locating platform, to realize that the position between three is accurate, help
In subsequent assembly manipulation.
After the upper cover plate of upper box, support plate and middle partition three assembly, the assembling process of upper box is finished, can will be upper
Cabinet is hung oneself down from locating platform 1, and removes pressing plate and tack welding seaming element 5, and by positioning angle square 50 and locating rod soldering group
Part 30 is installed on locating platform 1.The lower box of assembly to be positioned is then placed in locating platform 1, lower box has setting circle
Hole and pilot hole, using positioning cover plate 32 position lower box positioning round orifice, similar to the abovely, position cover plate 32 outer rim and
The inner wall of positioning round orifice fits, and physical dimension and the positioning round orifice size for positioning cover plate 32 are very nearly the same, so that lower box is fixed
Position is precisely；Meanwhile after long casing 31 wears pilot hole, pilot hole is fitted in using the gland 10 for being located at long 31 top of casing
Upper surface, and by the bottom plate of the abutting lower box of positioning angle square 50, it realizes and lower box is positioned at locating platform 1, gland 10 can
To be connected by fixed parts 20 such as bolts with long casing 31.
Reference book attached drawing 1 to attached drawing 4, locating platform 1 is equipped with step surface 11, and step surface 11 is compared to locating platform 1
Upper surface it is high, bottom plate of the step surface 11 to select a support upper cover plate and lower box, step surface 11 is considered as workbench, platform
The upper surface of terrace 11 is equipped with 13 phase of small positioning convex platform 12 and big positioning convex platform 13 namely small positioning convex platform 12 and big positioning convex platform
