[0027] The present invention will be further described in detail below in conjunction with the accompanying drawings.

[0028] Reference Figures 1 to 9 :Vertical double-workpiece multi-head slot milling machine, including a frame 1, a milling cutter power device 2, a front and rear drive device 3, an upper and lower drive device 4 and a pneumatic clamping device 5, a workbench 11 is provided on the frame 1, the milling cutter power device 2 is provided below the workbench 11, and the milling cutter faces upward. The front and rear drive device 3 is provided on the frame 1 and connected to the moving crossbeam 35, the upper and lower drive device 4 is connected to the milling cutter power device 2, the pneumatic clamping device 5 is provided on the workbench 11, and the pneumatic clamping device 5 is matched with the milling cutter power device 2.

[0029] When the vertical double-workpiece multi-head slot milling machine is in use, the two aluminum templates to be processed are placed at corresponding positions on the workbench 11, the workpieces are clamped by the pneumatic clamping device 5, and then the milling cutter power device 2 is driven to move forward and backward and up and down by the front and rear drive device 3 and the upper and lower drive device 4 to realize the processing of the workpiece.

[0030] For the architectural aluminum formwork of the pull-tab system, the cross-section of the aluminum formwork workpiece is U-shaped, and the surfaces to be processed are two side surfaces. Therefore, during processing, the pneumatic clamping device 5 first clamps and fixes one of the side surfaces, and after the processing of the side surface is completed, it is flipped up and down, and the other side surface is fixed and processed. There is no need to flip it 180° left and right, which reduces the workload when clamping the workpiece and improves the processing efficiency.

[0031] The milling cutter power device 2 includes a milling cutter 21 and a spindle motor 22. The milling cutter 21 is connected to the output shaft of the spindle motor 22. The milling cutter 21 is located below the workbench 11, with the milling cutter facing upward. The milling cutter 21 can be a multi-blade milling cutter, which is driven to rotate by the high-speed rotation of the spindle motor 22, thereby improving the milling efficiency of the milling cutter 21. By installing the milling cutter 21 below the workbench 11, when the workpiece is fixed above the workbench 11, it can protect the operator and improve the safety of operation; and when the milling cutter 21 is milling the groove, the debris generated by the milling cutter 21 falls directly below the workbench 11, avoiding the phenomenon of debris flying around and facilitating the collection of debris.

[0032] The front and rear drive device 3 includes a hydraulic cylinder 31, a horizontal slide rail 32, a slider 33, a mounting seat 34 and a moving beam 35. The horizontal slide rail 32 and the hydraulic cylinder 31 are both arranged on the frame 1. The horizontal slide rail 32 is located below the spindle motor 22. The slider 33 cooperates with the horizontal slide rail 32. The mounting seat 34 is fixed above the slider 33. The moving beam 35 is fixed on the mounting seat 34. The piston rod of the hydraulic cylinder 31 is connected to the moving beam. The extension and contraction direction of the piston of the hydraulic cylinder 31 is consistent with the length direction of the horizontal slide rail 32. The spindle motor 22 and the connecting lifting plate 42 and the transverse support plate 6 are suspended on the side of the moving beam 35. In actual use, two parallel horizontal slide rails 32 are fixedly installed at the bottom of the frame 1 by bolts, and each horizontal slide rail 32 is matched with a corresponding slider 33; the mounting seat 34 is fixed to the slider 33 by screws, and the moving beam 35 is fixed to the front end of the mounting seat 34 by bolts.

[0033] Therefore, when the milling cutter 21 needs to move forward and backward, the piston rod of the hydraulic cylinder 31 extends forward or pulls back, driving the moving beam 35 to move forward and backward along the horizontal slide rail 32, and then driving the spindle motor 22 to move forward and backward together, so that the milling cutter 21 connected to the output shaft of the spindle motor 22 moves forward and backward, realizing the forward and backward adjustment of the position of the milling cutter 21, and meeting the milling groove requirements of the workpiece.

[0034] The vertical double-workpiece multi-head slot milling machine also includes a transverse pallet 6, and the upper and lower driving device 4 includes a driving cylinder 41 and a lifting plate 42. The transverse pallet 6 is arranged on the moving beam 35, and the cylinder body of the driving cylinder 41 is fixed on the transverse pallet 6. The spindle motor 22 is fixed on the lifting plate 42. The lifting plate 42 is connected to the piston rod of the driving cylinder 41, and the piston rod of the driving cylinder 41 can move up and down.

[0035] A vertical dovetail groove is provided on the transverse moving pallet 6, and a guide rail 421 is provided on one side of the lifting plate 42. The guide rail 421 cooperates with the vertical dovetail groove, and the guide rail 421 can move up and down along the vertical dovetail groove. The transverse moving pallet 6 and the spindle motor 22 are respectively located on the opposite sides of the lifting plate 42.

[0036] The vertical double-workpiece multi-head slot milling machine of the present invention also includes a connecting plate 30, which is horizontally arranged and fixed to the top of the lifting plate 42 by screws. The piston rod of the driving cylinder 41 is connected to the lifting plate 42 through the connecting plate 30.

[0037] When the up and down position of the milling cutter 21 needs to be adjusted, the piston rod of the driving cylinder 41 extends upward or pulls back, and the piston rod of the driving cylinder 41 drives the connecting plate 30 to move up and down together, and the connecting plate 30 drives the lifting plate 42 fixed thereto to move up and down, so that the motor fixed on the lifting plate 42 moves up and down, realizing the up and down movement of the milling cutter 21 and meeting the milling groove depth requirement. By providing a vertical slide groove on the transverse support plate 6, and the guide rail 421 on the lifting plate 42 cooperates with the vertical slide groove, therefore, when the lifting plate 42 is lifted or lowered, the vertical slide groove guides the guide rail 421, which is conducive to the smooth lifting of the lifting plate 42 and improves the stability of the lifting of the milling cutter 21.

[0038] There are multiple milling cutters 21, and the spindle motor 22, the lifting plate 42, the upper and lower driving devices 6 and the transverse moving pallet 6 are all correspondingly multiple. A horizontal dovetail slide is provided on the back of the transverse moving pallet 6, and a horizontal dovetail slide 31 is provided on the moving crossbeam 3. The multiple transverse moving pallets 6 are all matched with the horizontal dovetail slide 31. Among them, the number of milling cutters 21 can be increased or decreased accordingly according to the length of the aluminum template and the number of slots to be processed. In actual use, the horizontal dovetail slide on the back of the transverse moving pallet 6 is matched with the horizontal slide 351 on the moving crossbeam 35. By moving the transverse moving pallet 6, the drive cylinder 41, the connecting plate 30, the lifting plate 42, the spindle motor 22 and the milling cutter 21 and other structures matched with the transverse moving pallet 6 can be driven to move together. By adjusting the position of the transverse moving pallet 6 on the horizontal slide 31 on the moving crossbeam 35, the distance adjustment between adjacent milling cutters 21 can be achieved, so that the milling cutter 21 is aligned with the position to be processed, meeting the processing requirements and being easy to operate.

[0039] The pneumatic clamping device 5 includes a first group of clamping cylinders 51, a second group of clamping cylinders 52 and a clamp seat 53. The first group of clamping cylinders 51 and the second group of clamping cylinders 52 are both arranged on the frame 1 and located below the workbench 11. One end of the clamp seat 53 is connected to the first group of clamping cylinders 51, and the other end is connected to the second group of clamping cylinders 52. The length direction of the first group of clamping cylinders 51 is parallel to the length direction of the second group of clamping cylinders 52.

[0040] Since two sets of clamping cylinders are arranged in parallel, when the aluminum template workpiece is clamped, the two workpieces can be tightened and fixed. Specifically, when the workpiece is fixed, the side to be processed of the U-shaped aluminum template is placed on the fixture seat 53, and the two workpieces are placed back to back, that is, the bottom surfaces of the two workpieces that do not need to be processed are close to each other; the opening direction of the U-shaped aluminum template is toward the first set of clamping cylinders 51 or the second set of clamping cylinders 52 on the corresponding side; when the position of the workpiece on the fixture seat 53 is determined, the first set of clamping cylinders 51 and the second set of clamping cylinders 52 clamp the corresponding workpiece to complete the clamping and fixing of the workpiece, which is convenient to operate. At the same time, since the side to be processed is positioned, that is, the clamping base surface is the milling groove surface, therefore, the processing error caused by the deformation of the aluminum template is greatly reduced by using the processing surface itself as the clamping base surface, and the processing accuracy is improved.

[0041] The first group of clamping cylinders 51 includes a plurality of first spinning cylinders 511, and the second group of clamping cylinders 52 includes a plurality of second spinning cylinders 521. The first spinning cylinders 511 correspond to the second spinning cylinders 521 one by one. One end of the fixture seat 53 is fixed to the cylinder body of the first spinning cylinder 511, and the other end is fixed to the cylinder body of the second spinning cylinder 521. The spinning arms of the first spinning cylinder 511 and the spinning arms of the second spinning cylinder 521 are both located above the fixture seat 53. Among them, one end of the fixture seat 53 is located on the upper end surface of the cylinder body of the first spinning cylinder, and is tightened and fixed to the cylinder body by screws; the other end of the fixture seat 53 is located on the upper end surface of the cylinder body of the second spinning cylinder, and is tightened and fixed to the cylinder body by screws. One first spinning cylinder 511 is connected to a corresponding second spinning cylinder 521 through a fixture seat 53, so that multiple fixture seats 53 are distributed along the length direction of the aluminum template workpiece, which is convenient for supporting the workpiece.

[0042] The pneumatic clamping device 5 also includes a clamp seat pressure block 55, which is L-shaped, fixed to the clamp seat 53, and the horizontal side of the clamp seat pressure block 55 is in close contact with the workbench 11. In a specific embodiment, the clamp seat pressure block 55 is fixed to the clamp seat 53 by bolts. In order to facilitate the clamp seat pressure block 55 to be fixed on the workbench 11, the workbench 11 is provided with a mounting step downward, and the clamp seat pressure block 55 cooperates with the mounting step. In actual use, a locking plate can be provided on the bottom surface of the clamp seat 53, and the locking plate and the clamp seat pressure block 55 are respectively located on opposite sides of the clamp seat 53, and the locking plate and the clamp seat pressure block 55 are tightened and fixed by bolts passing through the clamp seat 53, so that the clamp seat pressure block 55 is fixed at the mounting step, so that the clamp seat 53 can be fixed on the frame 1. By providing the L-shaped clamp seat pressing block 55 , it is convenient to determine the installation height positions of the first spinning cylinder 511 and the second spinning cylinder 521 on the frame 1 .

[0043] A limiting groove 531 is provided in the middle of the upper end surface of the clamp seat 53. By providing the limiting groove 531, the side surface of one of the workpieces to be processed can be limited. After one end of the side surface is pressed against one side wall of the limiting groove 531, the length direction of the workpiece is consistent with the length direction of the clamping cylinder group; after the position of one workpiece is confirmed, the other workpiece can be pressed against it back to back, and then the first spinning cylinder 511 and the second spinning cylinder 521 are started, so that the corresponding spinning arm can press the workpiece, which is convenient for the workpiece to remain flat and conducive to ensuring the processing accuracy.

[0044] The pneumatic clamping device 5 further includes a positioning plate 54, which is disposed on the frame 1 and is located on one side of the first group of clamping cylinders 51 and the second group of clamping cylinders 52. By providing the positioning plate 54, one end of the two workpieces can be abutted against the end surface of the positioning plate 54, which facilitates the clamping and fixing of the workpieces.

[0045] The positioning plate 54 is provided with a slide groove 541, and the positioning plate 54 is fixed to the frame 1 by screws penetrating the slide groove 541. The length direction of the slide groove 541 is consistent with the length direction of the workpiece. For workpieces of different sizes or different processing slots and holes, the screws on the slide groove 541 can be loosened, and then the position of the positioning plate 54 can be moved to adjust the starting positioning position of the workpiece, meet different processing requirements, and facilitate the rapid installation of the workpiece.

[0046] like Fig.10 As shown, the pneumatic clamping device 5 also includes a side push cylinder 56 and a side push plate 57. The cylinder body of the side push cylinder 56 can be fixed below the clamp seat 53 by a connecting plate and bolts. The side push plate 57 is connected to the piston rod of the side push cylinder 56. The clamp seat 53 is provided with a through hole 42. One end of the side push plate 57 extends out of the through hole 532 and is located on one side of the limiting groove 531. The side push plate 57 corresponds to the side wall on the other side of the limiting groove 531. Specifically, when the workpiece is placed on the limiting groove 531, one end of the workpiece abuts against the side wall (i.e., the reference surface) on the other side of the limiting groove 531, and then the piston rod of the side push cylinder 56 is pulled back, pulling the side push plate 57 to press the other end of the workpiece, and preliminarily clamping the workpiece.

[0047] There can be three side push cylinders 56, and there are three side push plates 57 corresponding to the side push cylinders 56, which is convenient for pressing the workpiece and ensuring that the milling aluminum template groove is perpendicular to the length direction.

[0048] The vertical double-workpiece multi-head slot milling machine of the present invention further comprises a chip guard plate 7 and an aluminum chip recovery drawer 8 (such as Fig.11As shown in the figure, the chip guard plate 7 is arranged above the workbench 11 and on both sides of the pneumatic clamping device 5, and the aluminum chip recovery drawer 8 is arranged on one side of the milling cutter power device 2 and below the workbench 11. Among them, a small amount of aluminum chips splashing out can be blocked by the chip guard plate 7, which further prevents the aluminum chips from flying around and ensures the safety of the operator. The aluminum chip recovery drawer 8 is arranged at the bottom of the frame 1, and the aluminum chips generated by the processing fall downward into the aluminum chip drawer 8. When the aluminum chips accumulate to a certain amount, the aluminum chip recovery drawer 8 is pulled out from one side of the frame 1 to clean up the aluminum chips, which is convenient for the recovery of aluminum chips.

[0049] The vertical double-workpiece multi-head slot milling machine also includes a control box 9 and an operation interface 10. The control box 9 is arranged above the workbench 11. The milling cutter power device 2 is electrically connected to the control box 9 and the operation interface 10 through wires. By providing the control box 9, the distribution of the power supply wires of each spindle motor 22 can be facilitated, and the installation of each power supply device in the control box 9 can be facilitated, the installation distribution of each structure can be facilitated, and the simplicity of the overall structure can be improved. By providing the operation interface 10, the control of the operation of each spindle motor can be facilitated.

[0050] The vertical double-workpiece multi-head slot milling machine of the present invention also includes a synchronous drive device 20, which includes a support frame 201, a synchronous shaft 202, a gear 203 and a rack 204. The support frame 201 is fixed on the mounting seat 34, and the synchronous shaft 202 is arranged on the support frame 20 and fixed by a bearing seat. There are two gears 203, which are respectively sleeved on both ends of the synchronous shaft 202 and fixedly connected. There are two racks 204, both of which are fixed on the frame 1. The gear 203 is meshed with the rack 204, and the rack 204 is arranged parallel to the horizontal slide rail 32. Among them, the support frame 201 is fixed on the two horizontal slide rails 32 by bolts, and the synchronous shaft 202 is sleeved on the two support frames 20. A bearing is sleeved between the synchronous shaft 202 and the support frame 20, which is convenient for the rotation of the synchronous shaft 202, reduces friction, and is conducive to improving the service life of the synchronous shaft 202. When the mounting seat 34 drives the milling cutter 21 to move along the horizontal slide rail 32, the support frame 201 moves together with the mounting seat 34, so that the synchronous shaft 202 also needs to move forward and backward. Since the gear 203 is meshed with the rack 204, when the support frame 201 moves, the gear 203 moves along the rack 204. Through the cooperation of the gear 203 and the rack 204, and the rack 204 is fixed on the frame 1, it is possible to prevent the crossbeam 35 from bearing too much weight, causing the mounting seat 34 to tilt, thereby ensuring the stability of the movement of the mounting seat 34, that is, ensuring the stability of the movement of the milling cutter 21, which is conducive to ensuring the processing accuracy.

[0051] The above are only preferred embodiments of the present invention. It should be pointed out that a person skilled in the art can make several modifications and improvements without departing from the inventive concept of the present invention, and these all fall within the protection scope of the present invention.
