Technical Field
The utility model relates to a shaft sleeve structure of a press machine.
Background
The press (including punching machine and hydraulic press) is a universal press with exquisite structure. The press has the characteristics of wide application, high production efficiency and the like, and can be widely applied to cutting, punching, blanking, bending, riveting, forming and other processes. The metal is plastically deformed and broken by applying strong pressure to the metal blank to process the part.
The shaft sleeve connected with the crankshaft on the press machine tool body is a key component on the press machine tool body, the original shaft sleeve is made of Q235, the forging method is adopted, and before welding, the inner ring and the outer ring of the shaft sleeve are machined, so that the cost is high and the manufacturing period is long; the original shaft sleeve structure adopts an integral structure, the shaft sleeve is inserted into the wallboard during assembly, and centering is difficult during assembly.
Disclosure of utility model
The utility model aims to solve the defects in the prior art and provides a shaft sleeve structure of a press machine.
The utility model provides a press axle sleeve structure, its characterized in that includes wallboard, first axle sleeve, second axle sleeve, the wallboard on be equipped with first through-hole, first axle sleeve on be equipped with the second through-hole along the axial, second axle sleeve on be equipped with the third through-hole along the axial, first axle sleeve and second axle sleeve are fixed respectively in the both sides of wallboard, the axis of first through-hole, second through-hole, third through-hole coincides mutually, the diameter of first through-hole, second through-hole, third through-hole is the same.
Working principle: adopt split type welded structure, weld two axle sleeves in the both sides of wallboard respectively, when satisfying axle sleeve length requirement, also make things convenient for the installation of axle sleeve.
In order to facilitate processing and installation, the first shaft sleeve and the second shaft sleeve are fixedly connected with the wallboard through welding.
In order to ensure the welding firmness, the inner sides and the outer sides of the first shaft sleeve and the second shaft sleeve are welded with the wall plate.
In order to ensure that the assembly of the shaft sleeve and the wallboard is firm enough, the inner side and the outer side of the shaft sleeve are welded during welding.
In order to prevent gaps from appearing at the lap joint position of the shaft sleeve and the wallboard during boring, welding seams between the inner side of the shaft sleeve and the wallboard are groove welding seams.
In order to ensure that the shaft sleeve can be firmly welded on the wallboard, the welding seam between the outer side of the shaft sleeve and the wallboard is a fillet welding seam.
The beneficial effects are that: compared with the prior art, the split type welding structure is adopted, the two shaft sleeves are respectively welded on the two sides of the wallboard, the length requirement of the shaft sleeves is met, the shaft sleeves are convenient to install, and compared with the original shaft sleeve structure, the split type welding structure is simple, economical and short in manufacturing period.

FIG. 3 is a schematic view of an original bushing assembly;
In the figure, 1, a crankshaft, 2, a shaft sleeve, 3 and a wallboard.
Detailed Description
The present utility model will be further described in detail with reference to the following examples and drawings for the purpose of enhancing the understanding of the present utility model, which examples are provided for the purpose of illustrating the present utility model only and are not to be construed as limiting the scope of the present utility model.
As shown in fig. 1-3, a crankshaft 1, a shaft sleeve 2 and a wallboard 3;
The shaft sleeve structure of the press comprises a wall plate 3, a first shaft sleeve 2 and a second shaft sleeve 2, wherein a first through hole is formed in the wall plate 3, a second through hole is formed in the first shaft sleeve 2 along the axial direction, a third through hole is formed in the second shaft sleeve 2 along the axial direction, the first shaft sleeve 2 and the second shaft sleeve 2 are respectively welded and fixed on two sides of the wall plate 3, the inner sides and the outer sides of the first shaft sleeve 2 and the second shaft sleeve 2 are welded with the wall plate 3, welding seams between the inner side of the shaft sleeve 2 and the wall plate 3 are groove welding seams, and welding seams between the outer side of the shaft sleeve 2 and the wall plate 3 are fillet welding seams; the axes of the first through hole, the second through hole and the third through hole are coincident, and the diameters of the first through hole, the second through hole and the third through hole are the same.
The processing process comprises the following steps: cutting: cutting two materials on a steel plate, and processing the two materials into two shaft sleeves 2;
And (3) assembling: welding two shaft sleeves 2 on two sides of the wallboard 3 to enable the axes of the two shaft sleeves 2 to coincide; during welding, the inner side and the outer side of the shaft sleeve 2 are welded, the welding seam between the inner side of the shaft sleeve 2 and the wall plate 3 is a groove welding seam, and the welding seam between the outer side of the shaft sleeve 2 and the wall plate 3 is a fillet welding seam.
Boring: boring holes on the shaft sleeves 2 at the projection positions of the holes on the wall plate 3, so that the holes of the two shaft sleeves 2 are communicated.
The shaft sleeve and the wallboard are connected to the crankshaft 1 after being welded.
The foregoing description of the preferred embodiments of the utility model is not intended to be limiting, but rather is intended to cover all modifications, equivalents, alternatives, and improvements that fall within the spirit and scope of the utility model.
