Embodiment Construction

[0018] exist figure 1 Among them, a tooling fixture for turning the flange seam of a complete machine, including a positioning bushing 1 with an inner hole 1, the positioning bushing 1 is quenched and tempered by ordinary No. 45 steel.

[0019] Such as figure 1 As shown, a keyway 5 is opened on the hole wall of the inner hole 2 of the sleeve end of the positioning sleeve 1 .

[0020] The inner hole 2 of the sleeve end of the positioning sleeve 1 is matched with the shaft extension of the motor to be turned. The cooperation between the two adopts a small clearance fit with high precision. The matching clearance should ensure that the inner hole and the shaft extension of the motor are coated. After applying lubricating oil, screw the motor shaft into the inner hole by hand. If the gap is too small, it will be difficult to install; if the gap is too large, the machining accuracy of the flange seam cannot be guaranteed.

[0021] The purpose of opening the keyway 5 is to instal...

Abstract

The invention relates to a frock clamp used for turning a flange spigot of a complete machine motor which is assembled, comprising a fixed bushing with an inner hole; a key slot is opened on the wall of the inner hole at the socket joint end of the fixed bushing; the inner hole at the socket joint end is matched with the shaft extension of the motor to be turned; a center positioning hole which is coaxial with the inner hole of the bushing is arranged at the positioning end of the fixed bushing. The frock clamp uses the center positioning hole at the positioning end of the bushing instead of a center hole at the shaft extension end of the motor, uses keys to circumferentially fix the shaft extension of the motor with the key slot on the inner hole of the bushing and carries out turning on the flange spigot of the complete machine through fit of front and rear lathe centers with the center positioning hole of the bushing and a center hole at the non-shaft extension end of the motor. The frock clamp has the advantages of simple structure, reasonable design, low cost, easy operation, accurate positioning, high production efficiency and high processing precision of workpieces.

Description

technical field [0001] The invention relates to a workpiece clamping, supporting and positioning device, in particular to a tooling fixture suitable for turning the motor flange seam of the motor after assembly. Background technique [0002] With the rapid development of modern industry, the demand for flange end cover motors is gradually increasing. In order to ensure the reliable operation of the equipment connected with it, the installation accuracy of the flange end cover motor is required to be high. What affects the installation accuracy is mainly the amount of runout between the flange seam of the motor flange end cover and the outer circle of the shaft extension. We know that the main factors affecting the runout of the flange are: the coaxiality of the flange end cover seam and the bearing chamber, the coaxiality of the seams at both ends of the frame, the precision of the rolling bearing, the shape and position deviation of the shaft, and the assembly process. At...
