[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] 1. The portable metal plane special milling grinder is provided with a socket, a handle, a connecting rod, a gear, a rack, a sliding rod and a movable plate. When the handle is pulled out of the socket, the first spring will be compressed, so that the staff can rotate the connecting rod through the handle, so that the gear connected to the connecting rod can push the rack to move, thereby pushing out the movable plate. At the same time, the movable plate will drive the sliding rod to slide in the rod sleeve, thereby expanding the contact surface with the workbench through the movable plate that can be extended from both sides of the base, so that the milling grinder can be stably placed on the workbench, and the staff can loosen the handle to make the first spring rebound to push the baffle to drive one end of the handle to be inserted into the socket, thereby fixing the connecting rod to prevent the gear from rotating accidentally.

[0013] 2. The portable metal plane special milling grinder is provided with a fixed rod, a sliding plate, a magnetic box, a rotating rod, a strong magnetic plate and a fixed block. After the movable plate extends a certain distance from both sides of the base, the staff pushes the sliding plate to slide on the fixed rod so that the magnetic box can contact the workbench. Then the staff rotates the rotating rod through the fixed block so that the strong magnetic side of the strong magnetic plate faces the workbench, thereby fixing the milling grinder on the workbench through magnetic adsorption to prevent accidental movement due to vibration when the milling grinder is working. When the milling grinder needs to be moved, the staff only needs to rotate the rotating rod again to make the strong magnetic side of the strong magnetic plate away from the workbench, so that the staff can move the milling grinder through the micro roller.

DETAILED DESCRIPTION

[0020] The technical solution of this patent is further described in detail below in conjunction with specific implementation methods.

[0021] like Figure 1-5 As shown, the utility model provides a technical solution: a portable special milling machine for metal planes, comprising a guide column 1, a handle 2 is connected above the guide column 1, a longitudinal workbench 3 is slidably installed on the guide column 1 through a screw assembly, a transverse workbench 4 is slidably installed on the longitudinal workbench 3 through a screw assembly, a processing table 5 is connected in front of the transverse workbench 4, a mounting plate 6 is connected above the processing table 5, a motor 7 is mounted on the mounting plate 6, a driving wheel 8 is connected to the output shaft of the motor 7, a transmission belt 9 is installed on the driving wheel 8, and the driving wheel 8 is connected to a driven wheel 10 through the transmission belt 9.

[0022] A milling cutter 11 is installed below the driven wheel 10, and a base 12 is installed below the guide column 1. A fixed circular plate 13 is connected to one side of the base 12, and a rod sleeve 14 is connected inside the base 12. A fixed plate 15 is connected between the two rod sleeves 14. A rack 17 is slidably connected in the fixed plate 15. A slide groove 16 is provided on the fixed plate 15. The slide groove 16 is T-shaped. The part of the rack 17 that slides in the fixed plate 15 is engaged with the slide groove 16. A sliding rod 19 is connected to the side of the movable plate 18 close to the rack 17. The sliding rod 19 slides in the rod sleeve 14. The longitudinal workbench 3 and the transverse workbench 4 can be moved longitudinally and transversely respectively through the screw assembly, so as to adjust the position of the milling cutter 11 on the workpiece. The staff can conveniently carry the milling machine through the handle 2, and the slide groove 16 on the fixed plate 15 can limit the movement of the rack 17 to prevent the movable plate 18 from being unable to move due to the skew of the rack 17.

[0023] One end of the rack 17 is connected to a movable plate 18, a connecting rod 24 passes through the center of the fixed circular plate 13, a plurality of sockets 30 are provided on the fixed circular plate 13, one end of the connecting rod 24 is connected to a rotating plate 25, the other end of the connecting rod 24 extends into the interior of the base 12 and is connected to a gear 26, the gear 26 is meshed with the rack 17, a micro roller 20 is connected under the movable plate 18, the rack 17 is pushed to move by the rotation of the gear 26, so that the movable plate 18 extends from both sides of the base 12, and the micro roller 20 connected under the movable plate 18 can make the movement of the movable plate 18 more flexible and facilitate the staff to move the milling machine.

[0024] A handle 27 is slidably connected to the rotating plate 25, and one end of the handle 27 close to the fixed circular plate 13 is inserted into the socket 30 and is connected to a baffle 28. A first spring 29 is connected to one side of the baffle 28, and one end of the first spring 29 is connected to the rotating plate 25. The baffle 28 connected to one end of the handle 27 can prevent the handle 27 from detaching from the rotating plate 25, and when the handle 27 is pulled, the baffle 28 will compress the first spring 29, so that the first spring 29 pushes the handle 27 to be inserted into the socket 30 when it rebounds, thereby fixing the connecting rod 24.

[0025] A fixed rod 21 is connected to one side of the movable plate 18, and a sliding plate 22 is slidably connected to the fixed rod 21. A second spring 31 is sleeved on the fixed rod 21, and one end of the second spring 31 is connected to the sliding plate 22, and the other end of the second spring 31 is connected to the movable plate 18. A magnetic box 23 is connected below the sliding plate 22, and a rotating rod 32 is rotatably connected inside the magnetic box 23, and a strong magnetic plate 33 is connected to the rotating rod 32, and a fixed block 34 is connected to one end of the rotating rod 32. The staff adjusts the angle of the strong magnetic plate 33 by rotating the rotating rod 32, thereby changing the strength of the magnetic force. When the magnetic force weakens, the second spring 31 rebounds, pulling the sliding plate 22 upward to make the magnetic box 23 detach from the workbench, so that the staff can move the milling machine.

[0026] The working principle of the utility model is:

[0027] By pulling the handle 27 out of the socket 30, the baffle 28 will compress the first spring 29, so that the staff can rotate the connecting rod 24 through the handle 27, so that the gear 26 can push the rack 17 to move, thereby pushing out the movable plate 18, and at the same time the movable plate 18 will drive the sliding rod 19 to slide in the rod sleeve 14, thereby expanding the contact surface with the workbench through the movable plate 18 that can be extended from both sides of the base 12, and the extended sliding rod 19 can assist in supporting the movable plate 18 to prevent the movable plate 18 from tilting and causing the milling machine to tip over. The staff pushes the sliding plate 22 to slide on the fixed rod 21 so that the magnetic box 23 can contact the workbench, and then rotates the rotating rod 32 to make the strong magnetic side of the strong magnetic plate 33 face the workbench, thereby fixing the milling machine on the workbench by magnetic force, and the longitudinal workbench 3 and the transverse workbench 4 can move longitudinally and transversely respectively through the screw assembly, so as to adjust the position of the milling cutter 11 on the workpiece to complete the milling and grinding of the workpiece.
