Description

Technical Field

[0001] The utility model relates to the technical field of machining jigs, in particular to a cantilever locking device with multi-angle adjustment for machining. Background Art

[0002] In machining, workpieces are typically clamped flat on a machine tool and fixtures before being processed by machining equipment. Clamps such as clamps, vises, and locking plates are commonly used to hold the workpiece in place. This conventional clamping method completely blocks the bottom of the workpiece, resulting in a large obstruction area and the inability to adjust the machining angle. This makes it difficult for machining equipment to process the workpiece, especially for parts with special structures or specialized machining requirements.

[0003] Among the existing patents, the Chinese patent document with application number 202020698532.8 discloses a swing angle processing device, comprising: a tooling, the tooling extends along the Z-axis direction and can rotate around the Z-axis direction, the upper surface of the tooling is a horizontal plane, and the upper surface is mounted with a workpiece to be processed; a reference part, the reference part is mounted on the upper surface and spaced apart from the workpiece to be processed; a first processing part, when the angle of the tooling along the A and C directions is 0, the first processing part processes three reference surfaces on the reference part with the reference of the workpiece to be processed as the center according to the final swing angle value of the workpiece to be processed; a driving part, the driving part determines the angle to be rotated of the tooling along the A and C directions according to the final swing angle value of the workpiece to be processed, and rotates the tooling; a second processing part, the second processing part processes the workpiece to be processed according to the center of the three reference surfaces. When in use, this patent document also requires the workpiece to be processed to be mounted on the upper surface of the tooling, so that the bottom surface of the workpiece to be processed is completely blocked, and the adjustment of the processing angle of the workpiece to be processed is relatively limited, making it impossible to meet the processing requirements of multiple angles, and it is also impossible to ensure that the workpiece is processed smoothly. Therefore, the defects are very obvious and a solution is urgently needed. Utility Model Content

[0007] Furthermore, there are two side locking bolts, which are respectively located on the two side walls of the U-shaped groove. The upper and lower swing arms are horizontally provided with threaded holes. The side locking bolts pass through the side walls of the U-shaped groove and are threadedly connected to the threaded holes.

[0008] Furthermore, the end locking bolts penetrate the upper and lower angle adjustment seats and are threadedly connected to the ends of the left and right angle adjustment seats.

[0009] Furthermore, an escape space is formed between the upper and lower angle adjustment seats and the upper and lower swing arms, and the nut of the end locking bolt is located in the escape space.

[0010] Furthermore, the locking member is a locking bolt, which is threadedly connected to the left and right angle adjustment seats.

[0011] Furthermore, the cantilever locking device for machining multi-angle adjustment also includes a workbench, a processing space is opened in the middle of the workbench, the locking groove of the base is detachably connected with a locking screw, and the locking screw is used to lock the base on the workbench, and the U-shaped groove of the base is located above the processing space.

The swinging upper and lower swing arms drive the upper and lower angle adjustment seat to swing up and down, thereby adjusting the upper and lower angles of the upper and lower angle adjustment seat, thereby adjusting the upper and lower angles of the upper and lower angle adjustment seat, and thus adjusting the upper and lower angles of the workpiece. After the adjustment is completed, the side locking bolts are tightened. Alternatively, the end locking bolts can be slightly loosened to allow the left and right angle adjustment seat to swing left and right relative to the upper and lower angle adjustment seat, thereby adjusting the left and right angles of the left and right angle adjustment seat, thereby adjusting the left and right angles of the workpiece. After the adjustment is completed, the end locking bolts are tightened. By adjusting the left and right angles and the upper and lower angles separately or in combination, the swing angle (processing angle) of the workpiece during processing can be adjusted.
