Description
Technical Field
The utility model relates to a fastening frock for section of thick bamboo butt joint assembly belongs to the part assembly field.
Background
The end faces of two cylindrical parts are required to be butted in the assembling procedure of a certain product, then threaded holes are radially formed in the side walls of the butting port parts of the two cylindrical parts, screws are installed, the two cylindrical parts are butted into a whole through a flange structure, the product requires that the end face gap of the butting part of the two cylindrical parts is smaller than 0.05mm, and otherwise, potential safety hazards and potential quality hazards can be brought in a product test. Because the flange butt joint structure of two cylindric parts does not have the automatic positioning that the screw thread closes soon, when butt joint assembly, how to make two cylindric parts pinpoint, become whether the qualified key of assembly can be.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a fastening frock for cylinder butt joint assembly in order to solve the technical degree of difficulty of accurate location when two cylinders butt joint assemblies.
The utility model aims at realizing through the following technical scheme:
the utility model discloses a fastening tool for butt joint assembly of cylindrical parts, which comprises two parallel pressing plates, a screw rod and a compression nut, wherein the screw rod and the compression nut are used for providing fastening power;
the two parallel pressing plates comprise a front pressing plate and a rear pressing plate; the center of the rear end plate surface of the front pressing plate is provided with a front positioning table with the diameter matched with the inner diameter of the outer end of the first butt-joint cylindrical part, and two sides of the front positioning table on the rear end plate surface of the front pressing plate are respectively fixed with a screw; a rear positioning table with the diameter matched with the inner diameter of the outer end of the second butt-joint cylindrical part is arranged in the center of the front end plate surface of the rear pressing plate, and screw rod through holes corresponding to screw rods on the two sides of the front pressing plate are formed in the two sides of the rear positioning table of the rear pressing plate;
the outer end of the first butt-joint cylindrical part is radially positioned through the front positioning table, the outer end of the second butt-joint cylindrical part is radially positioned through the rear positioning table, two screws fixed to the rear end plate face of the front pressing plate respectively penetrate through the two screw rod through holes of the rear pressing plate, the two screw rods penetrate out of the two screw rod through holes and are connected with a compression nut, and the compression nut is rotated to enable the end faces of the first butt-joint cylindrical part and the second butt-joint cylindrical part to be in compression fit.
In order to avoid the damage of the cylindrical part to be assembled caused by excessive force during screwing operation of the compression nut, the compression nut adopts a torque nut.
Advantageous effects
