Description

Technical Field

[0001] The invention relates to a cutting device, in particular to an adjustable cutting device in mechanical engineering. Background Art

[0002] Multi-angle cutting in mechanical engineering is an important processing technology. It involves the use of various cutting tools and equipment to cut workpieces at different angles to meet specific design and manufacturing requirements. Mechanical cutting uses mechanical tools such as saws and files for cutting. For example, a band saw can cut metal materials through the movement of a circular saw blade. By adjusting the installation angle of the saw blade or the clamping angle of the workpiece, cutting at different angles can be achieved. This method is relatively low in cost, but has a slow cutting speed and limited accuracy. It is often used for some rough processing or small workpiece processing that does not require particularly high precision;

[0003] In the invention patent with application number 202410949360.X, a cutting device with multi-angle adjustment for mechanical engineering manufacturing is disclosed. The adjustment frame and the mounting frame are arranged to cooperate with each other. First, the control bolt is pulled outward so that the connecting plate can rotate freely on the inner side of the adjustment frame by using the rotating shaft. Since the connecting plate and the mounting frame are fixedly connected, the mounting frame can be used to drive the upper end of the equipment body to tilt, so that the cutting blade installed on the side of the equipment body can be adjusted to the required tilt angle for cutting, thereby realizing that the cutting device can be adjusted at multiple angles. , effectively improving the practicality and efficiency of the cutting device. The threaded rod and the limit plate cooperate with each other. First, by rotating the threaded rod, the limit plate is driven to move on the inner side of the fixed support frame by using the anti-slip sheet, so that the distance between the limit plate and the rear clamping plate can be adjusted according to the size of the steel to be cut, so that the cutting device can fix steel of different sizes. Then, the retractability of the spring telescopic rod can be used to drive the fixed clamping plate to quickly fix the steel to be cut, avoiding the displacement of the steel due to cutting vibration, and effectively ensuring the cutting accuracy of the cutting device.

[0004] However, the above-mentioned multi-angle adjustable cutting device for mechanical engineering manufacturing is limited only by the control bolt inserted into the corresponding limit hole when the mounting frame is rotated on the adjustment frame to adjust the angle, resulting in low limiting strength and the angle can only be adjusted according to the position of the limit hole and cannot be infinitely adjusted. When the above-mentioned multi-angle adjustable cutting device for mechanical engineering manufacturing is used for cutting, the control handle is manually held to drive the device body to rotate and cut, so that sparks and debris generated during cutting are easy to fly toward the worker, which is easy to affect the cutting efficiency and pose a safety hazard.
