[0017] In order to make the technical solution of the utility model more clear, the utility model is further described below in conjunction with the specific embodiments of the drawings.

[0018] like Figure 1-4 As shown, a tool positioning and rotating fixing device according to an embodiment of the utility model includes a base plate 1, a placement block 2 is provided on the upper surface of the base plate 1, a slide groove 21 is provided on the surface of the placement block 2, and a limit fixing plate 3 is vertically provided at the end, and a rotation shaft 31 is symmetrically provided on both sides of the limit fixing plate 3, and a limit frame 4 is rotationally connected to the limit fixing plate 3 through the rotation shaft 31, and a sliding plate 5 is slidingly connected between the inner surfaces thereof, and a slider 51 is provided on the surface of the sliding plate 5 in the direction of the slide groove 21, and a height limit frame 52 is symmetrically provided on the surface of the sliding plate 5 on the opposite side of the slider 51, and the height limit frame 52 is overall in an "L"-shaped structure, and a fixing bolt 53 is vertically rotated on its surface, and a screw rod 6 passes through the limit frame 4 and is connected to the sliding plate 5, and an operating handle 61 is provided at its end.

[0019] The length of the limiting frame 4 is greater than the length of the placing block 2. When working, the limiting frame 4 is rotated by the rotating shaft 31 to maximize the limiting effect on the workpiece.

[0020] Among them, the width of the limiting fixing plate 3 is equal to the width of the placing block 2. When working, the workpiece is placed on the surface of the placing block 2 and contacts the surface of the limiting fixing plate 3, which maximizes the limiting effect on the workpiece.

[0021] Among them, the surface of the placement block 2 is provided with 6 slide grooves 21. When working, the limit frame 4 is rotated by the rotating shaft 31, and the slider 51 is further embedded in the slide groove 21, so as to ensure the stability of the sliding plate 5 during the sliding process.

[0022] Wherein, six sliding blocks 51 are disposed on the surface of the sliding plate 5 .

[0023] Among them, a group of height limit frames 52 are symmetrically provided on the opposite side of the sliding block 51. When working, the screw 6 is driven to rotate by rotating the operating handle 61, so that the sliding plate 5 is displaced. When the sliding plate 5 contacts the workpiece, the height limit frame 52 is located directly above the workpiece, and the workpiece is limited and fixed by rotating the fixing bolt 53.

[0024] Working principle: first install the present application on the operating equipment, then place the workpiece on the surface of the placement block 2 and contact it with the surface of the limiting fixing plate 3, then rotate the limiting frame 4 so that the sliding plate 5 drives the sliding block 51 to embed into the slide groove 21, and at the same time the limiting frame 4 can limit the workpiece, then rotate the operating handle 61 to drive the screw 6 to rotate, so that the sliding plate 5 makes a displacement movement on the surface of the placement block 2 to limit and fix the workpiece, when the sliding plate 5 contacts the surface of the workpiece, the height limiting frame 52 is directly above the workpiece, finally rotate the fixing bolt 53 to limit and fix the workpiece from top to bottom, after the workpiece is limited and fixed, the workpiece is processed by the operating equipment, thereby achieving the technical effect of ensuring the operating accuracy.
