Description

Reusable screwing sleeve for triangular arm ball pin

Technical Field

The invention belongs to the technical field of automobile part assembly, and particularly relates to a reusable tightening sleeve for a triangular arm ball pin.

Background

The ball pin screwing sleeve is mainly used for screwing and assembling the ball pin and the bolt of the triangular arm. The existing ball stud is screwed up, and the assembling action has the characteristics of large screwing moment, high use frequency of a sleeve and the like. At present, an integral type screwing sleeve is generally adopted for assembly operation, and the defects that the sleeve is easy to damage, a workpiece is easy to scratch and the like exist, so that the production cost is increased, and the product quality is reduced.

Disclosure of Invention

The invention aims to solve the defects of the prior art and provide a reusable screwing sleeve of a triangular arm ball pin, which can protect a workpiece during assembly and reduce the maintenance cost after the fatigue deformation of the sleeve.

The technical scheme adopted by the invention is as follows: the utility model provides a reusable screwing sleeve of triangle arm ball round pin, includes the sleeve body, a plurality of flutings of circumference equipartition are followed to sleeve body head end, sleeve body tail end is equipped with the box spanner interface, every fluting department sets up the screw along the axial, every fluting department is along the vertical connection slide rail of sleeve body head end inner wall, the slide rail is connected with the tooth cover cooperation that is used for spacing triangle arm ball round pin, the tooth cover includes top installation face and spout, top installation face passes through bolt fastening with the screw laminating, spout and slide rail laminating. Each gear sleeve is provided with a slot matched with the sliding rail of the sleeve body to transmit torque.

In a further preferred structure, the slide rail is of a rectangular block structure.

In a further preferred configuration, the socket wrench interface is connected to a pneumatic or electric wrench.

In a further preferred construction, the plurality of slots comprises 6.

In a further preferred structure, knurling is pressed on the side surface of the socket cylinder of the socket wrench.

The material strength of the sleeve body is higher than that of the ball pin and higher than that of the gear sleeve, so that the service life of the sleeve body can be effectively prolonged, and the risk of scratching a workpiece in the fastening process can be reduced; the gear sleeve and the sleeve body are detachably designed, and the gear sleeve can be replaced only after fatigue damage of the gear sleeve, so that the use and maintenance cost of the sleeve is reduced.

The invention can effectively reduce the scratch of the workpiece during assembly; simultaneously, its detachable tooth cover can reduce sleeve use maintenance cost to a great extent.

Drawings

FIG. 1 is a schematic structural view of the present invention;

fig. 2 is a schematic structural view of the sleeve body.

Detailed Description

The invention will be further described in detail with reference to the following drawings and specific examples, which are not intended to limit the invention, but are for clear understanding.

As shown in fig. 1 and 2, the triangular arm ball pin connecting structure comprises a sleeve body 1, wherein a plurality of grooves are uniformly distributed at the head end of the sleeve body 1 along the circumference, a socket wrench interface 6 is arranged at the tail end of the sleeve body 1, a screw hole 4 is axially formed at each groove, a sliding rail 5 is vertically connected at each groove along the inner wall of the head end of the sleeve body 1, the sliding rail 5 is connected with a gear sleeve 2 used for limiting a triangular arm ball pin in a matching manner, the gear sleeve 2 comprises a top mounting surface 2-1 with a hole and a sliding groove 2-2, the top mounting surface 2-1 is fixed with the screw hole 4 through a bolt 3 in a fitting manner, and the sliding groove 2-2 is attached with the sliding rail 5.

The slide rail 5 is a rectangular block structure.

The socket wrench interface 6 is connected with a pneumatic or electric wrench.

The plurality of slots includes 6.

The side surface of the cylinder body of the socket wrench interface 6 is pressed with knurling patterns.

As shown in fig. 1, a sleeve body 1, a gear sleeve 2, and a bolt 3. As shown in fig. 2, the gear sleeve 2 is constrained by a slide rail 5 on the sleeve body 1 and is fastened by a bolt 3 and a screw hole 4 on the sleeve body; and after the six gear sleeves 2 are assembled, the reusable screwing sleeve of the triangular arm ball pin is obtained.

When in use, the socket wrench interface 6 is connected with a wrench; then the ball pin is matched with the sleeve, and the tooth sleeve 2 is matched with the ball pin to transfer force, so that the ball pin is fastened.

During maintenance, the bolt 3 of the gear sleeve 2 to be replaced is loosened, and the gear sleeve 2 is detached and replaced.

Those not described in detail in this specification are within the skill of the art.
