Description

Technical Field

[0001] The utility model relates to the technical field of vises, in particular to a precision vise with rotatable jaws. Background Technique

[0002] A vise, also known as a bench vise, table vise or iron tiger, is a widely used tool for clamping and fixing workpieces for processing. A vise generally consists of a base, a vise body, a fixed jaw and a movable jaw, and a transmission mechanism (such as a screw, a handle, etc.) for moving the movable jaw.

[0003] The angle of the common vise jaws is fixed. When one side of a special-shaped part is a bevel, in order to better fix it, it is necessary to replace the jaw with a beveled bottom surface for adaptation, which is rather troublesome. Therefore, a precision vise with rotatable jaws is proposed. Content of the Utility Model

[0022] The present utility model provides a technical solution, a precision vise with rotatable jaws. Please refer to Figure 1 , Figure 2 and Figure 3 , including;

[0023] A base plate 1, a fixed plate 2 is arranged on the left side of the upper end of the base plate 1, a moving plate 3 is arranged on the right side of the upper end of the base plate 1 and located on the right side of the fixed plate 2. Side blocks 7 are arranged inside both the fixed plate 2 and the moving plate 3. A jaw 8 is arranged on one side inside the side block 7;

[0024] A fixed shaft 16 is arranged on one side outside the side block 7, and the fixed shaft 16 penetrates and extends outside the fixed plate 2 and the moving plate 3. The fixed shaft 16 is rotatably connected to the fixed plate 2 and the moving plate 3;

[0025] A brake disc 17 is arranged on the outside of the fixed shaft 16, and an angle gauge 18 is arranged on one side outside the brake disc 17;

[0026] A side shell 19 is arranged on one side below the brake disc 17, and the side shell 19 is connected to the fixed plate 2 and the moving plate 3.

Sliders 21 are arranged on both sides outside the brake disc 17 inside the side shell 19, and the sliders 21 are in threaded fit with the double-headed screw 20. A clamping plate 22 is arranged at the upper end of the slider 21, and a brake pad 23 is arranged on one side inside the clamping plate 22.

[0027] Please refer to Figure 1 , a fixed block 4 is arranged on the right side of the upper end of the base plate 1, and the fixed block 4 is connected to the base plate 1. An adjusting screw 5 is installed inside the fixed block 4, and the adjusting screw 5 is in threaded fit with the fixed block 4. The adjusting screw 5 is used to control the movement of the moving plate 3.

[0028] Please refer to Figure 1 , a rocker 6 is arranged at one end outside the adjusting screw 5, the adjusting screw 5 is rotatably connected to the moving plate 3, and the rocker 6 is used to rotate the adjusting screw 5.

[0029] Please refer to Figure 3 , a cavity 10 is arranged on one side inside the side block 7, and a connecting rod 11 and a limit pin 14 are installed in sequence from top to bottom inside the cavity 10.

[0030] Please refer to Figure 3 , an insertion plate 9 is arranged on one side inside the cavity 10 outside the jaw 8.
