Detailed Implementation

[0016] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0017] Please see Figure 1 and Figure 2 , Figure 1 This is a side view of the entire utility model. Figure 2 This is a top view of the entire utility model.

[0018] This utility model provides a clamping device suitable for high-frequency fixture replacement, including a press worktable 2 and a magnetic disassembly and assembly assembly. The magnetic disassembly and assembly assembly includes a press fixture 1, an electromagnet fixing plate 3, an electromagnet 4, three positioning pins 5, and an electromagnet power supply 6. The press fixture 1 includes a connecting seat 101, a top plate 102, a connecting ring 103, a connecting groove 104, a positioning groove 105, and a lifting handle 106. The electromagnet power supply 6 includes a power box 601 and a power cord 602. The aforementioned solution solves the problems of long replacement time and high production cost of existing multi-variety fixtures. It can be understood that the aforementioned solution can position the press fixture 1 using the positioning pins 5 on the press worktable 2 during disassembly and replacement, ensuring the press fixture 1 is properly positioned. The center of the press head of the press machine coincides with the center of the press fixture 1, while ensuring that the electromagnet 4 is in the preset position on the base plate of the press fixture 1. When the power supply 6 of the electromagnet powers the electromagnet 4, the electromagnet 4 has no magnetic output. At this time, there is no locking force when replacing the press fixture 1, which facilitates replacement and fixture positioning. When the press fixture 1 is positioned on the press machine worktable 2, and the power supply 6 of the electromagnet powers the electromagnet 4, the electromagnet 4 outputs magnetic force, which attracts the press fixture 1 to the press machine worktable 2, completing the clamping. This control method can reliably clamp the fixture on the worktable after the equipment is powered off, preventing accidental replacement of the fixture. This effectively solves the problems of long replacement time and high production cost of existing multi-variety fixtures.

[0019] In this specific embodiment, the pressing fixture 1 is detachably connected to the press machine worktable 2 and is located at the center above the press machine worktable 2. The electromagnet 4 is fixedly connected to the press machine worktable 2 and is located at the internal center of the press machine worktable 2. The electromagnet fixing plate 3 is located below the press machine worktable 2, and the electromagnet fixing plate 3 is fixedly connected to the electromagnet 4 and is located below the electromagnet. The electromagnet 4 is fixed on the electromagnet fixing plate 3. Then, the fixing plate assembly is installed from the bottom onto the mounting hole of the press machine worktable 2. The pressing fixture 1 is positioned on the positioning pin 5 on the press machine worktable 2.

[0020] Among them, the three positioning pins 5 pass through the pressing fixture 1 and are detachably connected to the press machine worktable 2, and are located inside the upper part of the press machine worktable 2, and the positioning pins 5 are located on one side of the electromagnet 4.

[0021] Secondly, the output end of the electromagnet power supply 6 passes through the electromagnet fixing plate 3 and is detachably connected to the electromagnet 4, and is located on the lower side of the electromagnet 4. The electromagnet power supply 6 is set on one side of the press workbench 2. The electromagnet power supply 6 is connected to the electromagnet 4, and the magnetic output of the electromagnet 4 is controlled by controlling the on and off of the power supply.

[0022] The connecting seat 101 is detachably connected to the press worktable 2 and is located at the upper center of the press worktable 2. The top plate 102 is fixedly connected to the connecting seat 101 and is located above the connecting seat 101. The connecting ring 103 is fixedly connected to the top plate 102 and is located at the lower center of the top plate 102, and the connecting ring 103 is located at the inner center of the connecting seat 101. The connecting groove 104 is fixedly connected to the top plate 102 and the connecting seat 101 respectively and is located inside the top plate 102 and the connecting seat 101. The positioning groove 105 is fixedly connected to the top plate 102 and is located inside the top plate 102, and the positioning groove 105 is located on one side of the connecting groove 104. The lifting handle 106 is fixedly connected to the top plate 102 and is located on one side of the top plate 102.

[0023] One end of the power cord 602 passes through the electromagnet fixing plate 3 and is detachably connected to the electromagnet 4, and is located below the electromagnet 4. The power box 601 is detachably connected to the power cord 602 and is located at the end of the power cord 602 away from the electromagnet 4.

[0024] When using this invention to disassemble and replace the pressing fixture 1, the positioning pin 5 on the press machine worktable 2 is used to position the pressing fixture 1, ensuring that the center of the press head coincides with the center of the pressing fixture 1. At the same time, the electromagnet 4 is positioned at a preset position on the base plate of the pressing fixture 1. When the power supply 6 of the electromagnet energizes the electromagnet 4, the electromagnet 4 has no magnetic output. At this time, there is no locking force when replacing the pressing fixture 1, which facilitates replacement and fixture positioning. When the pressing fixture 1 is positioned on the press machine worktable 2, and the power supply 6 of the electromagnet energizes the electromagnet 4, the electromagnet 4 outputs magnetic force, which attracts the pressing fixture 1 to the press machine worktable 2, completing the clamping. This control method ensures that the fixture remains reliably clamped on the worktable after the equipment is powered off, preventing accidental fixture replacement. This effectively solves the problems of long replacement time and high production cost of existing multi-variety fixtures.

[0025] The above-disclosed embodiments are merely preferred embodiments of the present utility model and should not be construed as limiting the scope of the present utility model. Those skilled in the art can understand that implementing all or part of the above-described embodiments and making equivalent changes in accordance with the claims of the present utility model are still within the scope of the utility model.
