Embodiment Construction

[0011] like figure 1 and figure 2 , a simple metal bushing interference installation tool, including mold bolt 1 and gasket 2, pressure block 3, handle nut 4; The inner diameter of the sleeve 6 after installation; the gasket 2 and the pressure block 3 are made of aluminum, which is light in weight and soft in material, and can well protect the contacted double ear parts 5 and shoulder bushing 6, and the inner diameter of the gasket 2 is larger than The diameter of the polished bolt rod is 1 mm, which is convenient for the bolt to penetrate, and at the same time ensures that the pressure area is as large as possible and the force is uniform; the inner part of the handle nut 4 is threaded. Steel rods, the two ends of the steel rods are pier heads.

[0012] Press the shoulder bush 6 into the hole 5 of the double ear part by screwing the thread to generate tension, and select the corresponding size of the bolt 1 and handle nut 4 according to the working space and the size of th...

Abstract

The invention provides a simple metal bushing interference installation tool. The simple metal bushing interference installation tool comprises a bolt, a gasket, a pressing block and a handle nut. Thebolt adopts a hexagon socket head cap screw, and the size and the dimension of the bolt are decided by an operation space condition; the gasket and the pressing block are made of aluminum materials so as to be light in mass and soft in texture, a workpiece and a bushing contacting the gasket and the pressing block can be well protected, the outer diameters of the gasket and the pressing block canbe increased or decreased according to an actual space size condition, and even shapes can be changed; the inner diameter of the gasket is 1mm larger than the diameter of a bolt polish rod, so that the bolt can penetrates through conveniently, meanwhile, a compression area is ensured to be as large as possible, and the uniformity in stressing is realized; a threaded hole is formed in partial length in the handle nut, an unthreaded hole is formed in the rest length in the handle nut, a steel bar penetrates through a part, 15mm far away from an end, of the side of the unthreaded hole, and two ends of the steel bar are provided with piers; and a tensile force is produced through screwing a screw thread so as to press the bushing into a hole, and the bolt and the nut with corresponding sizesare selected according to an operation space and the size of the bushing, so that interference installation of multiple bushings with different sizes and different forms can be realized.

Description

technical field [0001] The invention relates to a simple metal bush interference installation tool. Background technique [0002] Common interference installation methods for metal bushings include: press-in method, thermal expansion method and cold-shrink method. When the interference is small or the connection requirements are not high, the press-in method is usually used, that is, directly using a hammer to add spacers Pressing in by tapping or using a press; when the matching requirements are high and objective conditions permit, the thermal expansion method or cold installation method is usually used to cool the bushing with liquid nitrogen or heat the oil / water of the parts to be installed , Put the bushing directly. If the interference is large, the bushing should be cooled with liquid nitrogen or the oil / water to be installed should be hit with a hammer and a pad immediately or pressed in with a press. The method of using a hammer and pads has high requirements for ...
