The bottom plane, the middle part of the rear clamping block 15 is provided with a cutting edge 161 along the sliding direction, and a connecting groove 162 is provided between the cutting edge 161 and the front end of the rear clamping block 15. The front slide 13 is fixedly connected to the first double slide rail 12, and the front slide 13 is aligned with the front part of the base 11. The front part of the base 11 is provided with a fixing seat 17 with a side surface being a right-angled trapezoid. The trapezoidal slope of the fixing seat 17 is 45 degrees. The right-angled plane of the fixing seat 17 is fixedly connected to the front part of the base 11, and the fixing seat 17 is provided on the inclined surface. There is a ball screw linear slide 18 parallel to it, and a front clamping block 16 is horizontally provided on the top of the ball screw linear slide 18. The rear half of the front clamping block 16 has the same structure as the front half of the rear clamping block 15. The arc-shaped bottom connection of the front clamping block 16 is also provided with a circular hole 163 that passes through left and right. The front clamping block 16 and the rear clamping block 15 are arranged horizontally opposite to each other. A first servo motor 19 is provided at the front end of the fixing seat 17. The ball screw linear slide 18 is connected to the first servo motor 19 through a ball screw. A lifting mechanism 3 is vertically provided on the ball screw linear slide 18, and a milling mechanism 4 is slidably connected to the lifting mechanism 3. Laser sensors 5 are provided on both sides of the front clamp 16. The light of the laser sensor 5 passes through the circular hole 163. The laser sensor 5 is electrically connected to the lifting mechanism 3. A slot-type photoelectric switch 6 and a light-shielding plate 7 are provided on one side of the ball screw linear slide 18. The slot-type photoelectric switch 6 is electrically connected to the first servo motor 19. A locking mechanism 141 is fixedly connected to the rear side of the rear slide 14.

[0023] The above-mentioned chamfer milling machine is mainly used for chamfering the ribs of curved wide wall panels at 45°, which solves the deficiency that the existing equipment can only chamfer 45° for objects with straight shapes and parallel arrangements. The arrangement of the first double slide rail 12 and the front slide 13 and the rear slide 14 can chamfer the ribs of curved wall panels of different lengths and widths. The rear half of the front clamping block 16 has the same structure as the front half of the rear clamping block 15, and its arc-shaped bottom clamps the wall panel, and the rib is stuck in the connecting groove 162. The part of the rib that needs to be chamfered at 45° is placed in the cutting edge 161, and then the rear slide 14 is locked with the first double slide rail 12, and then the length of the telescopic rod 22 is adjusted to make the lower pressing block 23 close to the rib that needs to be chamfered. At this time, the first cylinder 26 contracts to make the rib stuck in the groove of the lower pressing block 23, and cooperates with the lifting mechanism 3, milling mechanism 4, photoelectric sensor, etc. to make operation more convenient and safe.

[0024] As Figure 1 , Figure 5 shown, the pressing mechanism 2 includes a rotating seat 21 arranged at the rear part of the rear sliding table 14. A telescopic rod 22 with adjustable length is rotatably connected to the rotating seat 21. The telescopic top end of the telescopic rod 22 is rotatably connected to a pressing block 23. A collar 24 limited by a bolt is sleeved on the rear end of the telescopic rod 22. A cylinder seat 25 is further arranged in front of the rotating seat 21. A first cylinder 26 is rotatably connected between the collar 24 and the cylinder seat 25. The setting of the telescopic rod 22 can press down wall plates with different lengths. The setting of the collar 24 can adjust the elevation angle of the telescopic rod 22. The contraction of the first cylinder 26 enables the pressing block 23 to press the rib of the wall plate.

[0025] As Figure 1 , Figure 2 , Figure 5 shown, a groove along the sliding direction of the rear sliding table 14 is arranged at the bottom of the pressing block 23, and the cross section of the groove is an isosceles trapezoid. The arrangement of such a groove shape facilitates the pressing fit between the pressing block 23 and the rib.

[0026] As Figure 1 , Figure 6 shown, the lifting mechanism 3 includes a mounting plate 31. A lifting rod 32 is vertically and fixedly connected to the mounting plate 31. A second ball screw 33 parallel to the lifting rod 32 is arranged at the rear side of the lifting rod 32. A second servo motor 34 is fixed at the top of the lifting rod 32. The second servo motor 34 is in transmission connection with the second ball screw 33. The milling angle mechanism 4 moves up and down along the lifting rod 32 through the second ball screw 33. The settings of the second ball screw 33 and the second servo motor 34 make the moving and stopping positions of the lifting mechanism more accurate and more convenient to operate.

[0027] As Figure 1 , Figure 6 shown, the milling angle mechanism 4 includes a machine shell 41. A milling cutter fixture 42 and a first motor 43 are arranged below the machine shell 41. The milling cutter fixture 42 and the first motor 43 are in transmission connection. The milling cutter fixture 42 is vertically arranged with respect to the ball screw linear slide 18. The structural design of the milling angle mechanism 4 is relatively conventional, which can save costs and is also convenient for maintenance.

[0028] As Figure 2 , Figure 4 shown, the ball screw linear slide 18 includes a second double slide rail 181. A chamfered plane is arranged at the top of the second double slide rail 181, and the chamfered plane, the top surface of the fixed seat 17 and the upper plane of the front sliding table 13 are flush. Such an arrangement makes the milling machine structure more compact and improves the equipment precision at the same time.

[0029] As Figure 1 , Figure 2 , Figure 4As shown, the light-shielding sheet 7 is provided at the lower part of the slide of the ball screw linear slide 18, and the groove-shaped photoelectric switch 6 is provided on the side of the slide rail of the ball screw linear slide 18. Such a setting facilitates and accurately controls the movement and stop of the ball screw linear slide 18, and is also more convenient to install.

[0030] As Figure 1 , Figure 2 , Figure 5 shown, the locking mechanism 141 is locked to the first double slide rail 12 by bolts. Such a setting has a simple structure and is convenient to operate.

[0031] As Figure 1 , Figure 2 shown, the first double slide rail 12 is a cylindrical guide rail. The guide rail with a cylindrical structure has strong load-bearing capacity, good stability, is convenient to install, and has high precision.

[0032] The working process of the present invention:

[0033] Step 1, clamp the wide-width wall panel. The arc-shaped bottom of the rear half of the front clamping block 16 and the front half of the rear clamping block 15 clamps the wall panel, and the rib is stuck in the communication groove 162. The part of the rib that needs a 45° chamfer is placed in the cutting edge 161. Then, lock the rear slide 14 to the first double slide rail 12, and then adjust the length of the telescopic rod 22 to make the pressing block 23 close to the rib that needs to be chamfered. At this time, the first cylinder 26 contracts, and the rib is clamped through the groove of the pressing block 23.

[0034] Step 2, before the milling angle operation, first perform tool setting detection. The lifting mechanism 3 drives the milling angle mechanism 4 to descend. The first servo motor 19 drives the ball screw linear slide 18 to adjust the milling cutter to the starting point of the work in the cutting edge 161. At this time, the laser sensor 5 detects the tool tip and sends a signal to the second servo motor 34. At the lowest point where the lifting mechanism 3 descends, the groove-shaped photoelectric switch 6 controls and restricts the stroke of the ball screw linear slide 18 and the oblique movement of the milling angle mechanism 4. Adjust the position of the groove-shaped photoelectric switch 6 with a lower position to limit the starting point of the work of the milling angle mechanism 4, and adjust the groove-shaped photoelectric switch 6 with a higher position to limit the end point of the work of the milling angle mechanism 4.

[0035] Step 3, during the milling angle operation, the ball screw linear slide 18 moves to the starting point of the work. At this time, the lifting mechanism 3 descends to the lowest point and stops. At this time, the milling cutter rotates, and the ball screw linear slide 18 drives the milling angle mechanism 4 to move obliquely upward to mill the rib.

[0036] Step 4, when the milling angle is completed, the lifting mechanism 3 first rises to make the milling cutter head leave the cutting edge 161 first, and then the ball screw linear slide 18 retracts to the starting point of the work.

[0037] When chamfering the second rib, only steps one, three, and four need to be repeated without retooling, which saves time, effectively prevents the tool tip from being damaged, and makes the operation more convenient and safe. Both the front clamping block and the rear clamping block are replaceable modules, and chamfers can be made on ribbed wide arc wall panels of different sizes.

[0038] It should be noted that in this text, relational terms such as first and second are only used to distinguish one entity from another, and do not necessarily require or imply any actual relationship or order between these entities.

[0039] Although the specific implementation manners of the present invention have been described above, those skilled in the art should understand that these are only examples, and various changes or modifications can be made to this implementation manner without departing from the principle and essence of the present invention. The protection scope of the present invention is only defined by the appended claims.
