[0024] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0025] Please see Figures 1-5 The present invention provides a technical solution: a vacuum suction multi-compatible quick-change fixture mechanism, including a fixed base frame 1, wherein the fixed base frame 1 has a rectangular structure;

[0026] The worktable 3 is bolted to the upper end of the fixed base frame 1, and a processing fixture 5 is movably installed on the upper end of the worktable 3.

[0027] Mounting slot 13 is located in the middle of the upper end of the workbench plate 3. Several fixed suction cups 12 are installed at equal intervals inside the bottom of the mounting slot 13 by bolts.

[0028] Vacuum pump 8 is installed inside the fixed base frame 1 by bolts. A multi-head connecting pipe 9 is installed on the upper end of vacuum pump 8. The upper end of the multi-head connecting pipe 9 passes through the workbench plate 3 and connects to the bottom end of the fixed suction cup 12.

[0029] The mounting slot 13 has a rectangular structure. The bottom of the mounting slot 13 and the position relative to the fixed suction cup 12 are provided with connecting through holes. The vacuum pump 8 is equipped with a control switch. The fixed suction cup 12 has a circular structure when viewed from above. A baffle is installed on the front side of the fixed bottom frame 1 by bolts, and a smooth plate is installed in the middle of the bottom of the processing fixture 5.

[0030] The worktable 3 has a continuous structure, with rectangular slots 4 on both sides of its top. Positioning strips 11, also rectangular, are bolted to the bottom of both sides of the machining fixture 5. This allows the machining fixture 5 to be placed on the worktable 3, with its bottom contacting and pressing against the upper end of the fixed suction cup 12 installed inside the mounting slot 13. When fixing the machining fixture 5, the vacuum pump 8 is activated to remove air from the fixed suction cup 12 through the multi-head connecting pipe 9, thus ensuring the fixed suction cup... A negative pressure is generated inside the 12, which fixes the processing fixture 5 through the fixed suction cup 12, increasing the stability of the processing fixture 5 during use. When a different processing fixture 5 is needed, the vacuum pump 8 is turned off to make the fixed suction cup 12 lose its suction force, thus preventing the processing fixture 5 from losing its constraint force, and the processing fixture 5 can be replaced. The replacement and installation are quicker and can be completed without any tools. Different materials can be processed by changing to the corresponding processing fixture 5, increasing the compatibility during processing.

[0031] A reserve battery 6 is bolted to both sides of the bottom of the fixed base frame 1. The reserve battery 6 is electrically connected to the vacuum pump 8 through wires. A fixed frame plate is bolted to the middle of the inner cavity of the fixed base frame 1. In this way, if the energy source fails unexpectedly during processing, the power of the reserve battery 6 can be used directly. This will not prevent the failure of the power supply from causing the inability to replace, install, and process normally, and will increase the stability and resistance to accidents during processing.

[0032] The upper end of the workbench 3 has fixing grooves 17 on both sides of the mounting slot 13. The fixing grooves 17 are all bolted with fixing electromagnetic blocks 16. The fixing grooves 17 are all rectangular in structure. The fixing electromagnetic blocks 16 are located directly below the positioning strip 11. The fixing grooves 17 are used to install and fix the fixing electromagnetic blocks 16.

[0033] A trigger mechanism 7 is installed on the top right side inside the fixed base frame 1. The trigger mechanism 7 includes a trigger cylinder 701, a movable plate 702, a mounting spring 703, a movable contact ring 704, and a fixed contact ring 705. The trigger cylinder 701 is bolted to the top right side inside the fixed base frame 1. A connecting air pipe 10 is bolted to the right side of the multi-head connecting pipe 9 at the left end of the trigger cylinder 701. The movable plate 702 is movably installed in the middle of the inner cavity of the trigger cylinder 701. A mounting spring 703 is bolted to the right side of the movable plate 702 and the right side of the inner cavity of the trigger cylinder 701. The movable contact ring 704 is screwed to the left side of the movable plate 702. The fixed contact ring 705 is bolted to the left side of the inner cavity of the trigger cylinder 701. Both the movable contact ring 704 and the fixed contact ring 705 are electrically connected to the fixed electromagnetic block 16 via wires. Thus, when the vacuum pump 8 is started, the connecting air pipe 10 pushes the air inside the trigger cylinder 701... The air on the left side is drawn away, creating a negative pressure state inside the left side of the trigger cylinder 701, and causing the movable plate 702 to move to the left. When the movable plate 702 moves to the left side inside the trigger cylinder 701, the movable contact ring 704 and the fixed contact ring 705 come into contact, which will activate the fixed electromagnetic block 16, making the fixed electromagnetic block 16 magnetic and magnetically attracting the positioning strip plate 11. This increases the firmness of the machining fixture 5 during replacement and installation, preventing insufficient firmness during processing, which could cause the machining fixture 5 to loosen and shift, affecting normal processing efficiency. When the movable plate 702 moves to the left side inside the trigger cylinder 701, it will stretch the mounting spring 703, making it easier to reset the movable plate 702 later by using the stretched mounting spring 703. This will separate the movable contact ring 704 from the fixed contact ring 705, disconnect the power supply to the fixed electromagnetic block 16, and cause the fixed electromagnetic block 16 to lose its magnetism.

[0034] The mounting spring 703 is made of spring steel. The outer perimeter of the movable plate 702 and the inner perimeter of the trigger cylinder 701 are polished. The placement plate 2 is movably installed on the middle of both sides of the fixed base frame 1. The upper perimeter of the placement plate 2 is equidistantly equipped with blocks. The placement plate 2 has a rectangular structure. The middle of both sides of the trigger cylinder 701 is provided with a through hole. When the placement plate 2 is installed on the middle of both sides of the fixed base frame 1, the plates to be processed and the processed plates can be placed on the upper part of the placement plate 2 on both sides. It is safer to place them directly on the ground. It is also quicker and easier to pick up and replace them. The blocks increase the stability of the plates when they are placed, preventing them from slipping and falling to the ground and being damaged.

[0035] Both sides of the placement plate 2 have a fixed fitting plate 14 bolted to the opposite side of the bottom end. At least two fixed fitting plates 15 are bolted to the middle of both sides of the fixed base frame 1. The upper end of the fixed fitting plate 15 is fitted and connected to the inside of the fixed fitting plate 14. The cross-section of the fixed fitting plate 14 is an inverted U-shaped structure. On the side of the fixed fitting plate 14 away from the fixed base frame 1, a support rod is bolted to the bottom end of the placement plate 2. When the placement plate 2 is installed to the middle of both sides of the fixed base frame 1, the fixed fitting plate 14 is installed to the outside of the fixed fitting plate 15 through the placement plate 2. The placement plate 2 can be directly fixed by the cooperation of the fixed fitting plate 14 and the fixed fitting plate 15, and the disassembly and installation are quicker.

[0036] Working principle: The present invention places the processing fixture 5 on the upper end of the worktable 3, and makes the bottom end of the processing fixture 5 contact and press against the upper end of the fixed suction cup 12 installed inside the mounting slot 13. When the processing fixture 5 is fixed, the vacuum pump 8 is started to remove the air inside the fixed suction cup 12 through the multi-head connecting pipe 9, and a negative pressure is generated inside the fixed suction cup 12, thereby fixing the processing fixture 5 through the fixed suction cup 12, increasing the firmness of the processing fixture 5 during use. When different processing fixtures 5 are needed, the vacuum pump 8 is directly turned off to make the fixed suction cup 12 lose its suction force, thus making the processing fixture 5 lose its constraint force, and the processing fixture 5 can be replaced. The replacement and installation are quicker and can be completed without any tools. Different materials can be processed by changing to the corresponding processing fixture 5, increasing the compatibility during processing.

[0037] Simultaneously, when the vacuum pump 8 is started, the air inside the left side of the trigger cylinder 701 is evacuated through the connecting air pipe 10, creating a negative pressure state inside the left side of the trigger cylinder 701. This causes the movable plate 702 to move to the left. When the movable plate 702 moves to the left side inside the trigger cylinder 701, the movable contact ring 704 and the fixed contact ring 705 come into contact, which activates the fixed electromagnetic block 16. This causes the fixed electromagnetic block 16 to become magnetic and magnetically attract the positioning strip plate 11, thereby increasing the stability of the machining fixture 5 during replacement and installation. This prevents the machining fixture 5 from becoming loose or shifting due to insufficient stability during processing, which would affect normal processing efficiency. When the movable plate 702 moves to the left side inside the trigger cylinder 701, it stretches the mounting spring 703, which is convenient for the movable plate 702 to be reset later by the stretched mounting spring 703. This causes the movable contact ring 704 to separate from the fixed contact ring 705, disconnects the power supply to the fixed electromagnetic block 16, causes the fixed electromagnetic block 16 to lose its magnetism, and causes the machining fixture 5 to lose its restraint.
