SUMMERY OF THE UTILITY MODEL
An object of the utility model is to overcome above-mentioned technique not enough, provide one kind, solve among the prior art great technical problem of upset arm weight.
In order to achieve the technical purpose, the technical scheme of the utility model provides a upset arm, a serial communication port, include:
the cross section of the connecting part is of an I-shaped strip structure;
a sleeve shaft portion having a cylindrical shape and provided at one end of the connection portion;
the assembling seat is arranged at the other end of the connecting part, the connecting plate is provided with a first through hole and a second through hole, and the outer edge of the assembling part extends to form a pressing surface.
Compared with the prior art, the beneficial effects of the utility model include: the utility model discloses a forging technology replaces original casting process, for the convenience of forging the shaping upset arm, has at first cancelled the fretwork hole that is used for alleviateing upset arm weight on the connecting portion, has got rid of the strengthening rib between assembly seat and connecting portion simultaneously. On one hand, the complexity of the appearance of the turnover arm can be reduced by removing the hollow holes and the reinforcing ribs, so that the forging forming difficulty is reduced. On the other hand, because the mechanical property of the part of the forging process is better, the I-shaped connecting part can be designed to be thinner on the basis of meeting the load requirement, and the reinforcing rib is not needed to improve the load capacity in the same way. Thereby reducing the whole material consumption of the turnover arm and further reducing the weight of the turnover arm. Meanwhile, in order to position the turning arm in the forming process, two ends of the sleeve shaft part extend outwards to form a positioning table.

Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
As shown in FIG. 2, the overturning arm A of the prior casting process is not good in mechanical property of the part formed by the casting process, and is also beneficial to processing the part with a complex appearance. Therefore, a reinforcing rib a100 is additionally arranged at the boundary of the stress concentration, the reinforcing ribs a110 and a120 in fig. 2 are turnover arms, and a plurality of holes a200 are also arranged on the reinforcing ribs for reducing the weight of the turnover arms.
As shown in FIG. 1, the whole overturning arm of the present invention adopts the forging process, and compared with the casting process, the material has more excellent mechanical properties. In order to meet the requirement of forging forming, the following technical means are adopted in the embodiment, including: a connecting portion 100, a sleeve portion 200, and a fitting seat 300.
The connecting portion 100 is used for connecting the sleeve portion 200 and the mounting seat 300, the connecting portion is strip-shaped, the cross section of the connecting portion is in an i shape, the i-shaped structure can improve the structural strength of the connecting portion 100, and compared with a cast-formed overturning arm, the forged material is tougher, so that the connecting portion 100 can be designed to be relatively thin, and meanwhile, the forming difficulty in the forging process is reduced. Weight-reducing hollowed holes originally designed on the connecting part 100 are eliminated. Meanwhile, as the material of the turnover arm in the forging process is tougher, connecting ribs at the junction of the connecting part 100, the sleeve shaft part 200 and the assembling seat 300 are eliminated. Therefore, the forging forming of the part is prevented from being influenced by the complicated contour of the forging.
As shown in fig. 3, the connection part 100 may be designed to have a stepped shape because the sleeve part 200 and the fitting seat 300 may not be in the same plane during the actual assembly process. Since the two ends of the connecting portion 100 are connected to the sleeve shaft portion 200 and the assembling seat 300, in order to avoid the stress concentration problem caused by the sudden size change, the boundary between the connecting portion and the connecting portion of the sleeve shaft portion 200 and the assembling seat 300 should be a transition curve to fit the outer edges of the assembling seat 300 and the sleeve shaft portion 200.
The sleeve portion 200 is cylindrical and is disposed at one end of the connecting portion 100, and the sleeve portion 200 extends outward and protrudes out of the connecting portion 100 to form a positioning stage 210, and the positioning stage 210 protruding out of the connecting portion can facilitate positioning in a forging process.
The mounting base 300 is disposed at the other end of the connecting portion 100, and has a first through hole 310, a second through hole 320 and a screw hole 330. The first through hole 310, the second through hole 320 and the screw hole 330 are assembly holes for the flip arm to cooperate with other components, and the outer edge of the assembly base 300 extends to form a pressing surface 340.
Compared with the prior art, the beneficial effects of the utility model include: the utility model discloses an adopt forging technology to replace original casting process, for the convenience of forging the shaping upset arm, at first cancelled the fretwork hole that is used for alleviateing upset arm weight on connecting portion 100, got rid of the strengthening rib between assembly seat 300 and connecting portion 100 simultaneously. On one hand, the complexity of the appearance of the turnover arm can be reduced by removing the hollow holes and the reinforcing ribs, so that the forging forming difficulty is reduced. On the other hand, because the mechanical property of the part of the forging process is better, the I-shaped connecting part 100 can be designed to be thinner on the basis of meeting the load requirement, and the load capacity is improved without reinforcing ribs in the same way. Thereby reducing the whole material consumption of the turnover arm and further reducing the weight of the turnover arm. Meanwhile, in order to position the turning arm in the forming process, two ends of the sleeve shaft part 200 extend outwards to form positioning platforms 210.
The above description of the present invention does not limit the scope of the present invention. Any other corresponding changes and modifications made according to the technical idea of the present invention should be included in the scope of the claims of the present invention.
