DETAILED DESCRIPTION

[0029] The following is combined with Figure 1 -Attached Figure 4 , further details of this application are given.

[0030] Example

[0031] A suction cup type vacuum fixing fixture, comprising a base frame 1, referring to Figure 1-Figure 3The base frame 1 serves as a supporting base, and a moving mechanism 3 is fixed on its upper end, and a fixing mechanism 2 is provided on one side of the moving mechanism 3. Inside the fixing mechanism 2, the pressure-maintaining shell 20 is located at the upper end and is connected to the adsorption shell 24 at the lower end through a partition 25. The air valve 23 and the air port 22 are respectively fixed on one side of the pressure-maintaining shell 20 and the adsorption shell 24 for regulating the vacuum state. A plurality of adsorption ports 29 are provided at the lower end of the adsorption shell 24, and an adsorption core 27 is provided in each adsorption port 29. A protective net 28 is fixed on the inner surface of the adsorption core 27, and a sealing ring 201 is provided on the outer surface of the adsorption core 27 to match the adsorption port 29.

[0032] Reference Figure 2-3 By cooperating with the fixing cylinder 26 and the fixing hole 21, a stable connection between the pressure-maintaining shell 20, the partition 25 and the adsorption shell 24 is ensured, thereby improving the stability of the overall structure. At the same time, the adsorption ports 29 are distributed in a rectangular array, thereby ensuring the extensiveness and uniformity of the adsorption force and improving the fixing effect. By setting the limiting ring 202, the adsorption core 27 is effectively prevented from loosening or falling off in the adsorption port 29, thereby improving the stability and reliability of the adsorption.

[0033] Reference Figure 4 The moving mechanism 3 includes a moving frame 30, the lower end of the moving frame 30 is fixedly connected to the upper end of the base frame 1, the motor 32 is installed on one side of the moving frame 30, and drives the threaded rod 34 to rotate through the output end, and the outer surface of the threaded rod 34 is threadedly sleeved with a moving plate 35, and the moving plate 35 is connected to the pressure-maintaining shell 20 of the fixed mechanism 2 through an adjustment frame 36 on one side. A plurality of adjusting screws 38 are provided on the inner surface of the adjusting frame 36, and the lower ends of these adjusting screws 38 are fixedly connected to the upper end of the pressure-maintaining shell 20, and the height adjustment is achieved through the adjusting nuts 37 on the outer surface.

[0034] Reference Figure 4 The mounting frame 33 provides a stable support for the motor 32, the sliding fit between the movable groove 31 and the movable plate 35 ensures the smooth operation of the movable mechanism 3, and the coordinated use of the adjusting groove 39 and the adjusting screw 38 realizes the flexible adjustment of the height and direction of the fixing mechanism 2, thereby improving the applicability and flexibility of the clamp.

[0035] The implementation principle of the embodiment of the present application is as follows: First, the opening or closing of the air port 22 is controlled by the air valve 23, so that a pressure difference is formed between the inside of the pressure-maintaining shell 20 and the adsorption shell 24 and the external atmospheric pressure. When the air valve 23 is opened and the vacuum pump is connected, which is not clearly shown in the figure, but is a conventional configuration, the air inside the adsorption shell 24 is extracted to form a negative pressure or vacuum state. At this time, due to the effect of the external atmospheric pressure, the workpiece is tightly adsorbed on the adsorption port 29 at the lower end of the adsorption shell 24. During the adsorption process, the adsorption core 27 plays a key role. It enhances the adsorption effect of the adsorption port 29, and through the tiny channels or structures inside it, the negative pressure is more evenly distributed on the adsorption surface. At the same time, the provision of the protective net 28 protects the adsorption core 27 from damage by external objects, and prevents fine particles or debris from entering the adsorption system and affecting the adsorption effect. In addition, the sealing ring 201 ensures a close fit between the adsorption port 29 and the workpiece, prevents gas leakage, and thus ensures the stability and durability of the adsorption.

[0036] The moving mechanism 3 mainly drives the threaded rod 34 to rotate by the motor 32, thereby realizing the translational movement of the moving plate 35. When the motor 32 is started, its output shaft drives the threaded rod 34 to rotate. Since there is a threaded matching relationship between the threaded rod 34 and the moving plate 35, the moving plate 35 will perform translational movement along its axial direction under the rotation of the threaded rod 34, and the translational movement of the moving plate 35 will drive the adjusting frame 36 to move together. The adjusting frame 36 realizes the flexible adjustment of the height and direction of the fixing mechanism 2 through the cooperation of the adjusting screw 38 and the adjusting nut 37. This design enables the clamp to be quickly adjusted according to different workpiece shapes and processing requirements, thereby improving work efficiency and processing accuracy. In specific operation, the moving speed and direction of the moving plate 35 can be controlled by adjusting the speed and direction of the motor 32. At the same time, the height of the fixing mechanism 2 can be fine-tuned by adjusting the position of the nut 37 on the adjusting screw 38 to meet different processing requirements.

[0037] The examples of this specific embodiment are all preferred embodiments of this application and are not intended to limit the scope of protection of this application. Identical components are represented by the same reference numerals. Therefore, any equivalent changes made based on the structure, shape, and principle of this application should be included in the scope of protection of this application.
