Deviation correction device for reaming bolt holes and manufacturing method thereof

Abstract

The invention discloses a deviation rectification device for reamed bolt holes and a manufacturing method of the deviation rectification device, and aims to provide a tool for reamed hole bolt connection, wherein the tool is short in maintenance time, low in maintenance intensity, economical and practical. The deviation rectification device comprises a part I and a part II which need to be connected through reamed bolts, holes A are formed in the part I, an eccentric bushing A is installed in each hole A, an eccentric hole is formed in the center of each eccentric bushing A, holes B are formed in the part II, an eccentric bushing B is installed in each hole B, an eccentric hole is formed in the center of each eccentric bushing B, the distance between the center of each hole A and the center of the corresponding hole B is set as e, the distance between the center of the corresponding eccentric hole and the center of the outer circle of each eccentric bushing A and the distance between the center of the corresponding eccentric hole and the center of the outer circle of each eccentric bushing B are g, the value of g is greater than or equal to 0.5e and is less than or equal to e, the end face of one end of each eccentric bushing A is provided with a tapered concave platform consistent with the axis of the corresponding eccentric hole, and the end face of one end of each eccentric bushing B is provided with a tapered convex platform matched with the tapered concave platform of the corresponding eccentric bushing A. The deviation rectification device for the reamed bolt holes and the manufacturing method of the deviation rectification device are suitable for manufacturing of the parts connected through the reamed bolts and particularly suitable for maintenance of the parts connected through the reamed bolts.

Description

technical field [0001] The invention relates to the field of tooling, in particular to a deviation correcting device and a manufacturing method for reaming bolt holes. Background technique [0002] Bolt connection generally consists of several groups of bolts to fix two or more parts to be connected together through bolt holes, which are divided into ordinary bolts and bolts with hinged holes. Ordinary bolts mainly carry axial force, and can also carry less demanding lateral force; while the bolts used for reaming holes must match the size of the hole and are used in occasions where lateral force is applied. The diameter of the screw part of the reaming hole bolt connection is the same as the basic size between the holes. The fit between the unthreaded part of the reaming hole bolt and the bolt hole is H7 / m6, which belongs to the transition fit (not clearance fit). It can be seen on the drawing That is, the hinged hole bolt and the hole wall are formed by a line. When ther...

Problems solved by technology

[0005] This method is a good method when newly processing parts connected by bolts with reamed holes, but after the parts are put into use, the bolt holes of the parts may be squeezed and enlarged or one of the connected parts may be damaged, for example, the groove The connection between the tooth block and the hub of the head wheel of the type conveyor is connected by twisted hole bolts. After the tooth block has been used for a period of time, the tooth block must be replaced if the tooth block wears out. According to the traditional method, in order to ensure the tooth block and the wheel hub bolts The hole can meet the connection and fit deviation. The wheel hub and the new tooth block must be equipped with drilled and reamed bolt holes. It is a very troublesome and time-consuming process to remove the wheel hub from the work site and go to the processing workshop to match the drilled reamer.
