SUMMERY OF THE UTILITY MODEL

The utility model aims at the above-mentioned problem that prior art exists, provide a lightweight adjustment arm casing, solved the big problem of adjustment arm weight.

The purpose of the utility model can be realized by the following technical proposal:

lightweight adjustment arm casing, including main part and stalk portion, main part and stalk portion are even as an organic whole, its characterized in that, one side that above-mentioned stalk portion was kept away from to the main part has the protrusion to be long banding strengthening rib, the strengthening rib sets up along the horizontal direction on the lateral wall of main part, the main part bottom outside has several bead, several the bead all is long banding and vertical setting, and the one end of several bead interval setting and several bead all extends to strengthening rib department, the concave portion that forms of main part lateral part between two adjacent beads, lie in the several on the main part bottom surface the mounting hole has all been seted up to the other end department of bead.

This lightweight adjustment arm casing passes through the setting of strengthening rib and bead, along the design that forms several T type additional strengthening outside the main part, the bulk strength of main part bottom has been strengthened, and simultaneously, the mounting hole that will be used for installing the adjustment arm lid is seted up at bead lower extreme department, make full use of the structure of bead, then the wall thickness of main part bottom other positions except the bead can corresponding reduce the concave recessed portion of formation, can satisfy the intensity demand of main part, also can reduce the weight of adjustment arm casing.

In the light-weight adjusting arm shell, the middle parts of the upper side and the lower side of the handle part are respectively provided with a concave notch, and the two sides of the upper side and the lower side of the handle part, which are positioned on the notch, are respectively provided with a convex rib which is protruded and is in a long strip shape. The design is strengthened to the stalk portion adoption I-beam type, and attenuate central part wall thickness reduces the casting heat festival, and it is loose to reduce the casting, is greater than tensile strength's physical characteristic according to nodular cast iron compressive strength, combines stress analysis's stalk portion to draw the compressive stress distribution, and the strengthening rib thickness at attenuate compressive stress's position further subtracts the weight.

In the light-weight adjusting arm shell, the main body is provided with a worm gear hole and a small helical gear hole in a penetrating manner along the vertical direction, the small helical gear hole and the small helical gear hole are arranged adjacently, the small helical gear hole is communicated with the worm gear hole, the main body is provided with a worm hole in a penetrating manner along the horizontal direction, the worm gear hole is communicated with the side of the worm hole, and the worm gear hole and the worm hole are in arc transition at the intersecting line. The arc transition is adopted at the intersecting line, the intersecting line is avoided, the internal entity is ensured to be maximum, the strength is optimal, and meanwhile, the flanging burrs formed by processing are reduced.

In the light-weight adjusting arm shell, the bottom of the main body is provided with a concave notch at the intersection of the worm gear hole and the bevel pinion hole, and the bottom wall of the notch and the side wall of the notch are in arc transition.

Compared with the prior art, the strength of the main body is enhanced through the design of the structures such as the reinforcing ribs, the convex ribs and the convex ribs, the wall thickness of other positions can be reduced under the condition of meeting the overall strength requirement, and therefore the weight of the whole adjusting arm shell is reduced.

Detailed Description

The following are specific embodiments of the present invention and the accompanying drawings are used to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

As shown in fig. 1 and 2, the light-weight adjusting arm shell is of an integrated structure and comprises a main body 1 and a handle 2 located on one side of the main body 1, a worm gear hole 3 and a bevel pinion hole 4 are formed in the main body 1 in a penetrating mode along the vertical direction and are arranged adjacently, the bevel pinion hole 4 is communicated with the worm gear hole 3, a concave notch 12 is formed in the position, located at the intersection of the worm gear hole 3 and the bevel pinion hole 4, of the bottom of the main body 1, and the bottom wall of the notch 12 is in arc transition with the side wall. The main part 1 is provided with a worm hole 5 along the horizontal direction, the worm wheel hole 3 is communicated with the side part of the worm hole 5, and the arc transition is arranged at the intersection line of the worm wheel hole 3 and the worm hole 5.

One side that the stalk portion 2 was kept away from to main part 1 has the protrusion to be long banding strengthening rib 6, this strengthening rib 6 sets up on the lateral wall of main part 1 along the horizontal direction, 1 bottom outside of main part still has the convex bead 7 of several, several bead 7 all is long banding and vertical setting, the upper end of 7 intervals of several bead sets up and several bead 7 all extends to strengthening rib 6 department, 1 lateral part of main part between two adjacent beads 7 is recessed to form recessed portion 8, the mounting hole 9 has all been seted up to the lower extreme department that lies in several bead 7 on the 1 bottom surface of main part.
