A sleeve bracket

technical field

The invention relates to a sleeve tool, in particular to a sleeve bracket. More precisely, the invention relates to disassembling and assembling two nuts at the same time, and belongs to the technical field of mechanical tools.

Background technique

Nowadays, bolts, nuts, screws and similar fastening parts are usually used for assembly connections in many mechanical fields. In order to ensure accurate assembly accuracy, socket wrenches with measurable torque are usually used to disassemble them one by one. Unfortunately, this greatly reduces the assembly efficiency, resulting in low assembly accuracy. Even in some types of work that need to quickly disassemble and assemble bolts, nuts, screws and similar fastening parts, it is usually necessary to rely on manpower to disassemble and assemble one by one, which makes the workload a lot and the work efficiency is low.

Contents of the invention

In order to solve the above technical problems, the present invention provides a sleeve bracket, which can disassemble and assemble two kinds of bolts, nuts, screws and similar fastening parts at the same time, and can also adjust the length of the connecting rod.

The technical solution adopted by the present invention in order to solve the above technical problems is: a sleeve bracket, including a mechanism for adjusting the length of the connecting rod, a bevel gear transmission mechanism, a housing, a mechanism for adjusting the length of the shaft, a mechanism for fixing the shaft, a shaft, and a sleeve connector . The adjustable connecting rod length mechanism is composed of a square slider, a square cavity, a concave node, an elastic ball, and a spring; Elastic ball, under the elastic ball is a spring; the square slider and the longitudinal axis are cast and connected vertically to form a T shape; the quadrilateral cavity and the square slider cooperate to slide, and the elastic ball cooperates with the concave node to change the connection. The length of the rod and the torque it bears; when the connecting rod rotates, the longitudinal axis also rotates, and the longitudinal axis is also the driving axis.

Further, the bevel gear transmission mechanism is composed of a shaft and a plurality of bevel teeth, and the shaft is connected with the bevel gear key to form a bevel gear transmission mechanism with accurate transmission ratio.

Further, the outer shape of the shell is cylindrical, and the transmission part of the bevel gear is spherical, all of which are formed by casting. When the shell is assembled, it is equivalent to embedded assembly, and finally the gaps can be welded and polished.

Further, when the bearing in the transmission mechanism for adjusting the length of the shaft is subjected to torque, the length will also change; therefore, one section of the shaft is set as a square, and the inside of the other section of the shaft is set as a square cavity, so that When mating, the length of the shaft can be changed and the torque can be transmitted; when the length of the shaft is changed, the length of the housing also needs to be changed, because the housing does not bear torque, so the housing adopts a cylindrical surface to slide freely, but in the process of free sliding There is a stopper limit, there is no limit stopper on the shaft, the maximum limit of the housing sliding is greater than the sliding limit of the shaft, so as to prevent the shaft from falling off.

Further, the shaft in the fixed shaft mechanism needs to bear torque, so bearings are used to support the shaft. The bearing is installed in the inner cavity of the cylindrical housing, and the inner diameter of the bearing at the inner cavity of the housing is larger than that of the inner cavity of the housing. The inner diameter of the cavity is concave; that is to say, the thickness of the concave cannot be greater than the thickness of the outer ring of the bearing, and the stepped axial fixation is realized; the bearing is fixed axially, but the shaft is also fixed.

Further, the said shaft has a transverse shaft and a longitudinal shaft, one end of which is connected with bevel gears, and the other ends of the two longitudinal shafts are provided with sleeve connectors.

Further, the sleeve connection head is consistent with the commonly used ones.

Beneficial effect:

According to the present invention, the torque can be transmitted vertically through bevel gear transmission, and an accurate transmission ratio can be obtained, so that the sleeve bracket installation sleeve can fasten two bolts, nuts, screws and the like of different types or the same type at the same time parts; more precisely, it can disassemble two bolts, nuts, screws and similar fastening parts, while the original socket can disassemble and assemble one bolt, nut, screw and similar fastening parts. The length of the shaft can be changed by adjusting the shaft length mechanism, and a certain range is obtained, so that it can simultaneously disassemble and assemble bolts, nuts, screws and similar fastening parts at any two points within a certain range of diameters. The length of the working arm can be changed by adjusting the length of the connecting rod, so that no auxiliary booster bar is required for labor saving.
