An electromagnetic suction cup fixing sleeve 4117 is fixedly installed on the outer wall of the mounting block 413, and the electromagnetic suction cup fixing sleeve 4117 is communicated with the fixed slot 4118. An electromagnetic suction cup 4116 is fixedly installed inside the electromagnetic suction cup fixing sleeve 4117, and the electromagnetic suction cup 4116 is attracted to the permanent magnetic clamping rod 4115. A clamping base plate 414 is fixedly installed on the top of the mounting block 4112.
[0033] A threaded sleeve 415 is fixedly installed on the top of the clamping base plate 414, and the internal thread of the threaded sleeve 415 is connected to a threaded rod 416.

[0034] During the process of this embodiment, when the electromagnetic suction cup 4116 is energized, the permanent magnetic clamping rod 4115 can be attracted to keep it in the fixed clamping groove 4118, thereby strengthening the connection between the mounting block 4112 and the mounting block 413; when the electromagnetic suction cup 4116 is de-energized, the permanent magnetic clamping rod 4115 slides to the inside of the circular slide groove 4113 through the reset spring 4114 and disengages from the fixed clamping groove 4118, so that the mounting block 4112 can be easily disassembled and the clamping parts can be quickly replaced. When processing workpieces of different types or sizes, there is no need for complicated tools and a lot of time to disassemble and install the entire tooling fixture. It is only necessary to replace the corresponding detachable clamping part, which effectively improves the processing efficiency and reduces the equipment adjustment time.
[0035] Working principle: The fixture is mainly composed of a support platform 1, a clamping and adjusting movable part 3, and a detachable clamping part 4. The support platform 1 has a support leg 2 at the bottom, and a support pad at the bottom of the support leg 2, which plays a role of stable support. The clamping and adjusting movable part 3 is on the outer wall on both sides of the support platform 1 for adjusting the position. The detachable clamping part 4 is on the top of the support platform 1 for clamping the workpiece; the support plate 311 is fixed to the outer wall on one side of the support platform 1 to provide support for the adjustment base 312, and the adjustment base 312 is fixed to the outer wall at the top of the support plate 311. The slide groove 313 thereon is used for the slider 315 to slide, so as to realize the movement of the component within a certain range. The outer wall at the top of the adjustment base 312 is equidistantly provided with positioning slots 314, and the slider 315 is in the slide groove 313 When the pull rod 3111 is pulled, the pull rod 3111 is slidably connected to the through hole 3113 on the fixed block 3114, and the other end is connected to the pull plate 3112, so that the positioning block 318 can slide along the positioning rod 316. When the workpiece placement platform 411 is fixed on the top of the support platform 1, the workpiece placement platform 411 is used to place the workpiece, and the pads 412 play a protective or auxiliary supporting role on the outer walls of the workpiece placement platform 411. The mounting block 413 is fixed on the outer wall of the fixing block 3114 on one side, and is connected to the clamping and adjusting movable part 3 through the fixing block 3114, and can move with it. The mounting groove 4111 on the inner wall of the mounting block 413 is used to engage the mounting block 4 112. A return spring 4114 is provided in the circular groove 4113 on the mounting block 4112. One end of the return spring 4114 is fixed to the inner wall of the circular groove 4113, and the other end is connected to a permanent magnetic clamping rod 4115. The permanent magnetic clamping rod 4115 can slide in the circular groove 4113. A fixed clamping groove 4118 is provided in the mounting groove 4111. The permanent magnetic clamping rod 4115 can engage with the fixed clamping groove 4118. The electromagnetic chuck fixing sleeve 4117 on the outer wall of the mounting block 413 is connected to the fixed clamping groove 4118 and an electromagnetic chuck 4116 is fixed inside. When the electromagnetic chuck 4116 is energized, it can attract the permanent magnetic clamping rod 4115 to keep it in the fixed clamping groove 4118, thereby strengthening the connection between the mounting block 4112 and the mounting block 413.When the electromagnetic chuck 4116 is powered off, the permanent magnetic clamping rod 4115 slides into the circular groove 4113 via the return spring 4114 and disengages from the fixed clamping groove 4118, allowing for easy removal and installation of the clamping block 4112. The threaded sleeve 415 at the top of the clamping base 414 is internally threaded with a threaded rod 416. Rotating the rotating wheel 417 at one end of the threaded rod 416 allows the threaded rod 416 to rotate within the threaded sleeve 415 and move up and down. One end of the threaded rod 416 passes through the top of the clamping base 414 and extends to the bottom, where it is rotatably connected to the clamping fixed block 418. When the threaded rod 416 moves downward, it drives the clamping fixed block 418 downward. The pad 419 at the bottom of the clamping fixed block 418 contacts and applies pressure to the workpiece, securing it to the workpiece placement platform 411. Conversely, rotating the threaded rod 416 upward releases the workpiece.
