[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] Reference Figures 1-4 Example 1: An automatic clamp for mechanical equipment includes a mounting plate 1. The top outer wall of the mounting plate 1 is fixedly connected to a double-headed cylinder 2 with an external air source by screws. Both piston rods of the double-headed cylinder 2 are fixedly connected to a plate frame 3. A connecting plate 4 is provided on one side of the outer wall of each of the two plate frames 3. A pressure sensor 5 is installed on one side of the outer wall of the connecting plate 4. A clamping plate 6 is fixedly connected to one side of the outer wall of the pressure sensor 5. A rubber anti-slip strip 13 is provided on the side of each of the two clamping plates 6 away from the pressure sensor 5.

[0025] Through the above scheme, the double-headed cylinder 2 drives the two side plates 3 to move synchronously, thereby clamping or releasing the workpiece with the clamping plate 6. The pressure sensor 5 (model: FUTEK LCM300) detects the clamping force in real time and feeds the signal back to the control system to achieve precise control of the clamping force. The rubber anti-slip strip 13 increases the friction between the clamping plate 6 and the workpiece, preventing the workpiece from sliding during processing and also protecting the surface of the workpiece.

[0026] In this embodiment, a pressure sensor 5 is installed inside the clamping plate 6. The pressure sensor 5 is connected to the control system and is used to provide real-time feedback on the clamping force and adjust the double-headed cylinder 2. The magnitude of the clamping force can be monitored in real time, avoiding the impact on processing quality due to excessive or insufficient clamping. With the precise control of the double-headed cylinder 2, the clamping force can be automatically adjusted according to the material and shape of different workpieces, improving the safety and stability of clamping.

[0027] In embodiment 2, the top outer wall of the mounting plate 1 is fixedly connected to a vertical cylinder 7 with an external air source by screws on one side of the double-headed cylinder 2. The piston rod of the vertical cylinder 7 is fixedly connected to a horizontal sliding member 8. Both ends of the horizontal sliding member 8 are provided with pull rods 9, and the bottom outer wall of the pull rods 9 is rotatably connected to a horizontally swinging bottom plate 10. The bottom of one side outer wall of the plate frame 3 is provided with adjacent side ears 11, and both sides of the bottom plate 10 are provided with sliding pins 12. The sliding pins 12 are slidably connected to the inner wall of the side ears 11.

[0028] Through the above-described scheme, the vertical cylinder 7 pushes the horizontal sliding member 8 to move up and down, thereby adjusting the height of the pull rod 9 and the bottom plate 10. The sliding engagement of the sliding pin 12 within the side lug 11 allows the bottom plate 10 to be angled according to the shape of the workpiece, ensuring a tight fit with the workpiece surface. The bottom plate 10 serves to prevent items from falling during clamping, improving the stability of workpiece support, and adapting to the processing needs of workpieces with different shapes.

[0029] In this embodiment, the vertical cylinder 7 and the horizontal sliding member 8 work together to adjust the support position according to the height and shape of the workpiece, providing reliable bottom support for the workpiece. The bottom plate 10 is used to prevent the item from falling during the clamping process. It is especially suitable for irregular or heavy workpieces, effectively preventing the workpiece from shaking or shifting during processing, and also expanding the applicability of the fixture.

[0030] A protective sleeve 14 is provided at the center of the bottom outer wall of the mounting plate 1, and a photoelectric sensor 15 is installed inside the protective sleeve 14 on the bottom outer wall of the mounting plate 1.

[0031] With the above solution, the photoelectric sensor 15 (model: Keyence PZ-G61N) is installed in the protective sleeve 14 at the bottom of the mounting plate 1, which can detect the position and existence status of the workpiece, ensure that the fixture performs clamping operation in the correct position, and improve the degree of automation and operational safety.

[0032] The lateral sliding member 8 includes a rectangular frame 81 and a rectangular rod 82. The rectangular frame 81 is fixedly connected to the piston rod of the vertical cylinder 7. One end of the rectangular rod 82 is slidably connected to the inner wall of the rectangular frame 81, and the pull rod 9 is fixedly connected to the other end of the rectangular rod 82.

[0033] With the above scheme, the horizontal sliding member 8 is composed of a rectangular frame 81 and a rectangular rod 82. The rectangular rod 82 slides within the rectangular frame 81, allowing the pull rod 9 to be adjusted horizontally according to the position of the plate frame 3, ensuring that the bottom plate 10 can maintain stable support under different clamping widths.

[0034] The top of one side of the outer wall of the plate frame 3 is fixedly connected with adjacent guide rods 16, and the guide rods 16 are slidably connected to the inner wall of the mounting plate 1.

[0035] Through the above scheme, the guide rod 16 ensures the stability and accuracy of the plate frame 3 during movement, prevents the plate frame 3 from tilting or shifting, and thus guarantees the clamping accuracy.

[0036] The mounting plate 1 has a top frame 17 welded to its top outer wall, and a motor mounting base 18 is fixedly connected to the center of the top outer wall of the top frame 17 by screws. Lifting rings 19 are provided on both sides of the top outer wall of the top frame 17.

[0037] Through the above scheme, the top frame 17 and the motor mounting base 18 provide a stable installation foundation for the clamp, while the design of the lifting ring 19 facilitates the overall handling and installation of the clamp, improving the flexibility and practicality of the equipment.

[0038] Working principle: During operation, the photoelectric sensor 15 first detects whether the workpiece is in place and whether its position is correct. When the workpiece is in the correct position, the control system activates the double-headed cylinder 2, driving the two side plates 3 to move synchronously, causing the clamping plate 6 to gradually approach the workpiece. The pressure sensor 5 monitors the clamping force in real time. When the set value is reached, the double-headed cylinder 2 stops operating, completing the clamping of the workpiece.

[0039] Simultaneously, the vertical cylinder 7 is activated, pushing the horizontal sliding member 8 downwards, which in turn adjusts the pull rod 9 and the bottom plate 10 to the appropriate height. The rectangular rod 82 of the horizontal sliding member 8 slides within the rectangular frame 81, adjusting the horizontal position of the bottom plate 10 in conjunction with the position of the plate holder 3, ensuring close contact between the bottom plate 10 and the bottom of the workpiece for stable support. The bottom plate 10 prevents the item from falling during clamping. The sliding pin 12 within the side lug 11 allows the bottom plate 10 to be adjusted at a slight angle according to the shape of the workpiece, ensuring optimal support.

[0040] During processing, pressure sensor 5 continuously monitors the clamping force and adjusts it promptly if there are any changes. After processing is completed, the double-headed cylinder 2 reverses its movement to release the workpiece, and the vertical cylinder 7 drives the bottom plate 10 to reset, awaiting the clamping operation of the next workpiece.

[0041] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
