[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in 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.

[0024] Reference Figure 1-Figure 3 The utility model provides an embodiment: a precise positioning device for a machining center, comprising a base 1, a processing table 2 is fixedly connected to the middle of the top of the base 1, a movable groove 5 is opened inside the processing table 2, four movable grooves 3 are opened at the top of the processing table 2 at equal distances from the outer end of the movable groove 5, and the middle parts of the four movable grooves 3 are rotatably connected with screw rods 6, the thread directions of the screw rods 6 on the left and right sides are consistent, and the thread directions of the screw rods 6 on the front and back sides are consistent, the adjacent ends of the screw rods 6 pass through the movable groove 5 and are fixedly connected with gears 7, and a driving assembly is arranged at the bottom end of the movable groove 5, the outer side of the top of the driving assembly is meshed with the gear 7, and the outer side of the screw rod 6 is threadedly connected with a movable assembly inside the movable groove 3 on the same side.

[0025] The left and right gears 7 are driven to rotate in opposite directions through the driving assembly, thereby driving the left and right screw rods 6 to rotate in opposite directions synchronously. The driving assembly simultaneously causes the front and rear gears 7 to rotate in opposite directions, thereby driving the front and rear screw rods 6 to rotate in opposite directions synchronously. As a result, the moving assembly moves toward the center of the processing table 2 inside the moving groove 3 on the same side, thereby positioning the fastener in the center of the processing table 2, thereby improving the positioning efficiency and positioning accuracy.

[0026] Reference Figure 2 and Figure 3 The driving assembly includes a motor 8, the output end of the motor 8 is fixedly connected to a rotating shaft 9, the top of the rotating shaft 9 is fixedly connected to a gear disk 10, the motor 8 is located at the bottom end of the movable groove 5 inside the processing table 2, the gear disk 10 is located at the bottom end of the movable groove 5, and the gear disk 10 is meshed with the gear 7.

[0027] The motor 8 drives the rotating shaft 9 to rotate, and the rotation of the rotating shaft 9 drives the toothed disc 10 fixed thereto to rotate synchronously, thereby causing the left and right gears 7 meshing with the toothed disc 10 to rotate in opposite directions and the front and rear gears 7 to rotate in opposite directions.

[0028] Reference Figure 2 and Figure 4 The moving assembly includes a moving block 11, which is threadedly connected to the screw rod 6 on the same side, and is slidably connected to the moving groove 3 on the same side. The middle part of the top of the moving block 11 is fixedly connected to a support block 13, and the middle part of the side of the support block 13 adjacent to the middle of the processing table 2 is fixedly connected to an electric telescopic rod 14, and the output end of the electric telescopic rod 14 is fixedly connected to a clamping block 16, and the width of the clamping block 16 is consistent with the width of the moving groove 3. The support block 13 is fixedly connected to the upper and lower ends of the electric telescopic rod 14 with a telescopic plate 15, and the output ends of the two telescopic plates 15 are fixedly connected to the clamping block 16.

[0029] When the four screw rods 6 rotate, they drive the moving block 11 on the same side to move inward or outward synchronously. When the four moving blocks 11 move inward, they drive the clamping block 16 to move synchronously. When positioning the external hexagonal fastener, since the length between the left and right ends of the external hexagon is inconsistent with the length between the front and rear ends, the two ends of the external hexagonal fastener with a shorter distance need to be positioned in the middle of the processing table 2 through the cooperation of the electric telescopic rod 14 on the same side. When the electric telescopic rod 14 is extended or retracted, the telescopic plate 15 is extended or retracted synchronously under the action of the electric telescopic rod 14 to provide good support for the clamping block 16.

[0030] Reference Figure 2 and Figure 4The front and rear ends of the left and right side clamps 16 and the left and right ends of the front and rear side clamps 16 are all obliquely fixedly connected with baffles 17, the outer end of the processing table 2 is provided with through grooves 4 on the outside of the movable groove 3, and the four through grooves 4 are all located at the top of the same side screw rod 6, and the moving block 11 is fixedly connected with a fixed plate 12 in the middle and upper part of the side away from the middle of the processing table 2, and the fixed plate 12 is slidably connected to the through groove 4 on the same side.

[0031] The baffles 17 and the fixing plates 12 on both sides of the clamping block 16 prevent the debris generated by the processing of the fastener from entering the interior of the moving groove 3 to hinder the moving efficiency of the moving block 11, thereby affecting the use of the positioning device.

[0032] Working principle: First, place the fastener on the processing table 2, and then drive the motor 8 to make the four clamps 16 move synchronously toward the center of the processing table 2. Depending on whether the fastener is round or hexagonal, it is selected whether to cooperate with the driving electric telescopic rod 14 to position the fastener in the center of the processing table 2. The baffles 17 and fixed plates 12 on both sides of the clamps 16 prevent debris from affecting the positioning efficiency.

[0033] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
