Vertically-assembled balance arm mechanism and adjustment method thereof

Abstract

The invention discloses a vertically-assembled balance arm mechanism and an adjustment method thereof. The vertically-assembled balance arm mechanism comprises a base and a guide rod column located on the base, wherein a sliding sleeve is installed in the middle of the guide rod column, the two ends of the sliding sleeve are respectively provided with a first linear bearing, a horizontal sliding plate which is perpendicular to the axial direction of the sliding sleeve is installed in the middle of the sliding sleeve, a suspender and a bearing are arranged at the top end of the guide rod column, one end of a balance crane is fixed on the suspender, and the other end of the balance crane is installed at one end of the sliding sleeve through a stud. The balance arm mechanism further comprises a linear bearing guide rod, wherein a horizontal sliding block where a second linear bearing is installed is arranged on the linear bearing guide rod in a sleeved mode, a front check block and a rear check block are installed at the two ends of the linear bearing guide rod respectively, a front clamping block and a rear clamping block are further arranged on the front check block, and a spanner is fixed on the front check block in a clamping mode through the front clamping block and the rear clamping block. According to the vertically-assembled balance arm mechanism and the adjustment method thereof, the electric or pneumatic spanner can stay at any position horizontally and vertically, and it is guaranteed that the spanner is located in the vertical direction all the time during movement and working.

Description

technical field [0001] The invention relates to the field of assembly technology of electronic and mechanical products, in particular to a balance arm mechanism for vertical assembly and an adjustment method thereof. Background technique [0002] Screws or bolts are used in many electronic and mechanical product assembly processes. In order to improve production efficiency and maintain the consistency of screw or bolt assembly torque, the commonly used assembly tools are electric wrench or pneumatic wrench. The use of electric wrench or pneumatic wrench to assemble electronic and mechanical products has the following characteristics and requirements: For flat assembly, it must be ensured that the screw or bolt is only subjected to vertical rotational force during the entire assembly process and cannot be tilted. Otherwise, it will cause the screw thread to be damaged, the product parts to be scrapped or the assembly not in place to produce substandard products. Due to the ...

AI Technical Summary

Problems solved by technology

However, in actual work, there may be multiple screws or bolts that an operator needs to assemble on the horizontal plane, which requires the operator to hold the column wrench and lead the balance crane to move the assembly on the plane.

And this kind of frequent mobile assembly, it is difficult to ensure that the wrench is vertical in the assembly, so that waste products appear, increase the production cost, and increase the labor intensity of the operator.
