Verticality adjusting device for rear baffles of hydraulic swing plate shears

Abstract

The invention discloses a verticality adjusting device for rear baffles of hydraulic swing plate shears. The verticality adjusting device comprises a rear baffle body, a rear baffle support vertical plate, a central connecting bolt, a fixed adjusting plate, a sliding adjusting plate, a central stopper, a left adjusting bolt, a right adjusting bolt and a check nut. The fixed adjusting plate, the sliding adjusting plate and the rear baffle support vertical plate are disposed from rear to front in sequence. The fixed adjusting plate is welded on the rear baffle body. The central stopper is disposed in slides at the centers of the fixed adjusting plate and the sliding adjusting plate and is in tight fit with a hole of the rear baffle support vertical plate. The central connecting bolt matches with a threaded hole of the fixed adjusting plate. The fixed adjusting plate and the sliding adjusting plate are tightly attached through a nut and a spring washer and are tightly pressed onto the rear baffle support vertical plate. The left adjusting bolt and the right adjusting bolt are disposed on left and right sides of the sliding adjusting plate and are tightened by the check nut and the central stopper. The verticality adjusting device is high in adjusting speed, convenient, easy, high in adjustment precision, and high in reliability.

Description

technical field [0001] The invention relates to a device for adjusting the verticality of a rear baffle plate of a hydraulic pendulum shearing machine. Background technique [0002] The adjustment of the vertical accuracy of the rear baffle plate of the hydraulic pendulum shearing machine not only affects the quality of the product, but also affects the adjustment of the parallel accuracy. The adjustment of the verticality of the rear baffle plate of the traditional hydraulic pendulum shearing machine is adjusted by two jacking screws at the top and bottom of the central connecting bolt. This adjustment mechanism has the following problems: 1. Since the upper and lower top screws can only be adjusted one by one, the adjustment amount and adjustment force are difficult to control, and repeated adjustments are required. The adjustment is difficult, slow, and low in precision; 2. The upper and lower top screws The jacking and retreating distances cannot be kept consistent, and...

AI Technical Summary

Problems solved by technology

This adjustment mechanism has the following problems: 1. Since the upper and lower top screws can only be adjusted one by one, the adjustment amount and adjustment force are difficult to control, and repeated adjustments are required. The adjustment is difficult, slow, and low in precision; 2. The upper and lower top screws The jacking and retreating distances cannot be kept consistent, and sometimes there is no retreating distance, and each adjustment will change the parallel accuracy of the rear baffle; 3. The jacking wire is a point-contact support, which is prone to looseness and slippage during the production process, and the reliability is poor. Adjustment

The verticality adjustment mechanism of the rear baffle plate of the hydraulic pendulum shearing machine not only makes it difficult to guarantee the product quality, but also affects the normal production and the use efficiency of the machine, and there are safety hazards in the adjustment during the production process.
