Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] See also Figure 1-3The utility model provides a technical solution: a precise positioning and quick clamping fixture, including a mounting flange 1, a support seat 2 is fixedly connected to the top of the mounting flange 1, a guide shaft 4 is fixedly connected to the top wall of the support seat 2, an electric push rod 3 is fixedly connected to the bottom wall of the support seat 2, a movable block 5 is fixedly connected to the outer wall of the electric push rod 3, a support shaft 6 is fixedly connected to the inner wall of the movable block 5, a movable rod 7 is movably connected to the outer wall of the support shaft 6, a through groove 8 is provided on the inner wall of the movable rod 7, a positioning block 9 is fixedly connected to the top of the movable rod 7, a placing table 10 is fixedly connected to the top of the electric push rod 3, a fixing frame 11 is fixedly connected to the outer wall of the placing table 10, a reset spring 12 is fixedly connected to the inner wall of the fixing frame 11, and a clamping block 13 is fixedly connected to one end of the reset spring 12, which is convenient for double clamping of the workpiece, thereby making the workpiece positioning more accurate through the effect of pre-positioning, and improving the firmness of the clamping, meeting people's work needs, and worthy of popularization and use.

[0020] Furthermore, the clamping block 13 forms a telescopic structure with the fixing frame 11 through the reset spring 12, and the clamping block 13 is arc-shaped when viewed from above, which facilitates the reset spring 12 to drive the clamping block 13 to reset and slide to pre-position the workpiece.

[0021] Furthermore, the guide shaft 4 is connected with the movable rod 7 through the through slot 8 , and the movable rod 7 is slidably connected with the guide shaft 4 through the through slot 8 , which facilitates the movable rod 7 to slide under the guidance of the guide shaft 4 .

[0022] Furthermore, the movable rod 7 is rotatably connected to the movable block 5 via the support shaft 6 , and both sides of the movable block 5 are "concave" shaped structures when viewed from above, which facilitates the movable block 5 to drive the movable rod 7 to rotate via the support shaft 6 .

[0023] Furthermore, the movable rod 7 has a "V"-shaped structure when viewed from the front, and there are two movable rods 7 symmetrically distributed, which facilitates the movable rod 7 to drive the positioning block 9 to move toward or away from each other after rotating.

[0024] Furthermore, the positioning block 9 is arc-shaped when viewed from above, and the inner wall of the positioning block 9 is inclined, and the positioning block 9 and the clamping block 13 are staggered, which facilitates the positioning block 9 to further position the workpiece.

[0025] When in use, first move the two clamping blocks 13 away from each other and squeeze the reset spring 12 to compress and deform, and then place the workpiece between the clamping blocks 13. At this time, the elasticity of the reset spring 12 drives the clamping block 13 to reset and slide to pre-position the workpiece, thereby preventing the workpiece from shifting when the subsequent positioning is not firm, thereby improving the positioning accuracy. Then start the electric push rod 3, so that the electric push rod 3 drives the movable block 5 to slide, and the movable block 5 drives the movable rod 7 to move downward. At this time, through the guide limit of the guide shaft 4, the movable rod 7 slides on the outer wall of the guide shaft 4 through the through groove 8, so that the movable block 5 drives the movable rod 7 to rotate together through the support shaft 6 and then approach each other, and then drives the two clamping blocks 13 to approach each other and further position the workpiece, thereby improving the firmness of the positioning.
