Mechanical butt assembly alignment adjusting device

Abstract

The invention discloses a mechanical butt assembly alignment adjusting device. A support table is connected to an adjusting mechanism which comprises a rotating pair, an X axial moving pair and a Z axial moving pair, so that the support table has functions of moving in X, Y and Z axial directions and rotating about the Z axial direction, and the positions of workpieces are adjusted. The mechanical butt assembly alignment adjusting device has the following advantages: the mechanical butt assembly alignment adjusting device improves the whole butt assembly alignment adjusting efficiency compared with traditional modes, can be applied to the butt assembly of parts with various specifications (machine types), is stable in efficiency, realizes no lifting operation, has such functions as prevention of fall and rollover of the workpieces caused by no control of potential energy, reduces the personal injury accident safety risk caused by hanger damage or workpiece shaking and operation error in the operation process to a greater extent, facilitates the realization of the operation standardization and the flow line operation, enhances the product quality, and can save the electric charge generated by using a crane and the maintenance cost of the crane (trolley) and the hanger.

Description

technical field [0001] The invention relates to a setting device for butt-joint assembly of larger workpieces A and B in the construction machinery manufacturing industry, in particular to a mechanical butt-joint assembly alignment adjustment device. Background technique [0002] At present, when the construction machinery manufacturing industry carries out the butt joint assembly of larger workpieces A and B, the main technologies used are: [0003] 1. Use A piece of tooling or auxiliary equipment to fix part A on the docking station, and the operator controls the crane (driving) to lift part B to the docking station, and supports (or pushes) part B by hand while cooperating with the pairing crane (Traveling) control adjusts the position and direction of component B to make it dock with the corresponding interface of component A, and then complete the connection and assembly work. [0004] 2. The mechanical adjustment device is assembled with the axial butt joint of the in...

AI Technical Summary

Problems solved by technology

[0006] 1. Due to the large weight and volume of the parts, a crane (driving car) is used to lift the workpiece. During the hoisting process, due to the shaking and instability of the parts, the operator must directly hold the workpiece for docking, so that the operator, equipment and facilities are in the workpiece lifting position. Collision occurs when the motion energy is out of control, or falling and tipping when the self-weight potential energy is out of control and other dangerous areas, the risk of safety accidents that cause personal injury during lifting operations is extremely high;

[0007] 2. The docking adjustment is completed by the operator to control the movement and lifting of the crane (crane), and at the same time, it is completed by hand (or push) by manpower. The accuracy mainly depends on the operator's personal operation ability and proficiency to ensure the operation sequence and adjustment method. And work efficiency varies from person to person, and it is difficult to standardize operations

[0008] The second technology is currently only used by a small number of companies. The docking efficiency of this technology is relatively stable, and the security is slightly improved compared with technology 1.

[0009] (1) It can only be used for the docking of parts that are assembled horizontally and coaxially;

[0010] (2) To ensure that the two components A and B are coaxial, the machining accuracy of the components and the sliding docking device is required to be high. The positioning of components A and B on the docking device must be accurate. If the positioning errors of parts A and B If it is slightly larger, the two parts will form a misalignment or angle, and the bolts (or screws) will not be able to be fastened after the butt joint, and the assembly cannot be completed;

[0011] (3) The two components need to be hoisted to the device by a crane (driving car) for positioning, and there is still manual uprighting and positioning by lifting and transporting, and it is still difficult to avoid the safety risk of accidents caused by lifting operations;

[0012] (4), not conducive to the realization of streamlined operations
