[0057] Embodiment 1:

[0058] Please combine Figures 1 to 13 As shown, the present invention provides a universal combined drilling and milling machine, which includes a frame 10 and a moving frame 11 slidably mounted on the frame 10, a moving seat 12 slidably mounted on the moving frame 11, and a drilling and milling head is mounted on the bottom end of the moving seat 12; the combined drilling and milling machine also includes:

[0059] A frame 10, wherein a working area is provided on the upper surface of the frame 10, and chip removal channels 101 are provided at both ends of the working area in the length direction;

[0060] A pair of load-bearing plate groups are provided, and the two load-bearing plate groups are symmetrically distributed at both ends of the width direction of the working area. A first clamping column 24 is slidably provided in the length direction of each load-bearing plate group. A driving component is installed on each load-bearing plate group, and the first clamping column 24 is moved in the length direction of the load-bearing plate group by the driving component. A first push plate 23 is fixedly installed on the lower surface of each load-bearing plate group, and the first push plate 23 is slidably supported in the working area;

[0061] A plurality of support plates 31 are provided and are located between the two bearing plate groups. A second clamping column 33 is fixedly mounted on the upper surface of each support plate 31. A second push plate 32 is fixedly connected to the lower surface of each support plate 31 through a second threaded block 321. The second push plate 32 is slidably supported in the working area.

[0062] The movable control components are provided with more than four and are all installed on the frame 10. Each first push plate 23 and each second push plate 32 correspond to a movable control component. When the combined drilling and milling machine processes the workpiece, according to the size of the workpiece to be processed, the movable control component moves the multiple support plates 31 and the two bearing plate groups to the corresponding positions, and then the workpiece can be placed so that the workpiece is supported by the two bearing plate groups and the multiple support plates 31. At this time, the placed workpiece is not in the correct position, and the movable control component continues to move the support plate 31 so that the second clamping columns 33 on the multiple support plates 31 are close to the workpiece. At the same time, the driving component makes the first clamping column 24 close to the workpiece. The multiple second clamping columns 33 and the multiple first clamping columns 24 push the workpiece to the correct position together, and clamp the workpiece to ensure the stability of the drilling and milling process.

[0063] When the two first push plates 23 and the plurality of second push plates 32 are located on the same straight line, the end faces of the two adjacent push plates are in contact with each other. During the processing of the workpiece, a large amount of debris generated will splash into the working area. After the processed workpiece is taken out, the mobile control component enables the two first push plates 23 and the plurality of second push plates 32 to move to the same straight line, and then enables the two first push plates 23 and the plurality of second push plates 32 to move synchronously along the length direction of the working area, so that the debris in the working area can be pushed into the chip removal channel 101, without the need for staff to regularly The work area is cleaned and the workload of the staff is reduced. In addition, a collection box 81 is arranged directly below each chip removal channel 101. The debris entering the chip removal channel 101 falls into the collection box 81 and is collected, thereby reducing the difficulty of collecting the debris. A magnet block 811 can be fixedly installed on one side surface of the collection box 81. After the collection box 81 is installed on the frame 10, the magnet block 811 fits and adsorbs the iron block on the frame 10, and the collection box 81 is fixedly installed on the frame 10. In this way, it is convenient to disassemble and install the collection box 81.

[0064] Based on the first embodiment, the solution in the first embodiment is further detailed in combination with the following specific working method, as described below for details.

[0065] Embodiment 2:

[0066] Some workpieces are large metal workpieces with heavy weight. After two bearing plate groups and multiple support plates 31 jointly support such workpieces, a large thrust is required to push the workpieces to the corresponding positions. In order to reduce the thrust, multiple first balls 211 can be rotatably installed on the upper surface of each bearing plate group, and multiple second balls 311 can be rotatably installed on the upper surface of each support plate 31. This can reduce the friction between the bearing plate group and the support plate 31. At this time, the thrust for pushing the workpiece to move is reduced, and the performance requirements for the power components are reduced.

[0067] As for the bearing plate group, it includes a fixed plate 21 and a movable plate 22; a fixed block 232 and a track block 233 are fixedly installed on the first push plate 23, the lower surface of the fixed plate 21 is fixedly connected to the fixed block 232, and a track groove 221 for the track block 233 to slide is arranged on the lower surface of the movable plate 22, and the lower surface of the movable plate 22 is in contact with the top of the track block 233, and a first electric telescopic rod 27 is fixedly installed on the fixed plate 21, and the movable end of the first electric telescopic rod 27 is fixedly connected to the movable plate 22. The combined drilling and milling machine can process a large number of workpieces, and different workpieces can be processed. The sizes of the parts are quite different. For some smaller workpieces, in order to enable the two bearing plate groups to support the two ends of the workpiece in the width direction, the movable end of the first electric telescopic rod 27 is extended to increase the overall length of the fixed plate 21 and the movable plate 22, so that the combined drilling and milling machine can still process workpieces of various sizes, and the combined drilling and milling machine still has high versatility. It should be noted that the length of the bearing plate group can be set to not less than two-fifths of the width of the working area. At this time, the length range of the bearing plate group is larger, and the size range of the workpieces that can be supported is wider.

[0068] The driving assembly includes a first motor 25 and a first threaded rod 26; fixed rods 222 are fixedly installed at both ends of the fixed plate 21 in the width direction, the first motor 25 is fixedly installed on the fixed rods 222, the first threaded rod 26 is rotatably installed on one of the fixed rods 222, a third sliding rod 29 is fixedly installed on the other fixed rod 222, a first clamping column 24 is slidably installed on the third sliding rod 29, one end of the first threaded rod 26 is fixedly connected to the output end of the first motor 25, a moving block 241 is fixedly installed on the bottom end of the first clamping column 24, one end of the first threaded rod 26 passes through the interior of the moving block 241 and is threadedly connected to the moving block 241, the first motor 25 drives the first threaded rod 26 to rotate, so that the first clamping column 24 moves along the length direction of the fixed rod 222.

[0069] As for the mobile control component, it is composed of a second motor 41 and a second threaded rod 42. The second motor 41 is fixedly installed on the outer surface of the frame 10, and the second threaded rod 42 is rotatably installed on the frame 10. The output end of the second motor 41 is fixedly connected to one end of the second threaded rod 42; wherein a first threaded block 231 is fixedly installed between the first push plate 23 and the fixed plate 21, and one end of the second threaded rod 42 passes through the interior of the first threaded block 231 and is threadedly connected to the first threaded block 231; a threaded hole for the second threaded rod 42 to pass through is opened on the second threaded block 321, and is threadedly connected to the second threaded rod 42.

[0070] Embodiment three:

[0071] The debris generated during drilling and milling processing, part of which splashes onto the workbench, and the other part falls onto the upper surface of the workpiece. After the workpiece is processed, the staff first needs to remove and collect some large debris for later recycling. After the workpiece is removed, there are still some small debris attached to the workpiece, and the workers need to use a water gun to rinse the workpiece for the next process. Therefore, it is also troublesome to handle the debris on the workpiece. In order to reduce the difficulty of handling, a pair of side panels 14 are fixedly installed on the frame 10. The two side panels 14 are respectively located in the width direction of the working area. At both ends of the upper part, a cleaning rod 51 is slidably installed between the two side plates 14, and nozzles 511 are evenly spaced in the length direction of the cleaning rod 51. An infusion tube group is installed on one side of the cleaning rod 51, wherein the infusion tube group includes a connecting tube 61, a delivery tube 62 and an adapter 63; the adapter 63 is fixedly installed on the cleaning rod 51, and the delivery tube 62 is slidably installed on the frame 10; one end of the connecting tube 61 is rotatably connected to the adapter 63, and the other end thereof is rotatably connected to the delivery tube 62, and the delivery tube 62 can deliver the cleaning liquid to the inside of the cleaning rod 51, and finally the cleaning liquid is delivered to the cleaning rod 51 by a plurality of nozzles 511. The cleaning liquid is sprayed out. When it is necessary to clean the debris on the workpiece, the cleaning rod 51 is first moved from one end of the workpiece to the other end. During this process, the cleaning rod 51 pushes the larger debris on the workpiece to make the debris separate from the workpiece. When the cleaning rod 51 moves from the other end of the workpiece to its one end and resets, the infusion tube group transports the cleaning liquid into the cleaning rod 51, and the cleaning liquid is sprayed on the surface of the workpiece by multiple nozzles 511 to wash away the fine debris on the surface of the workpiece. After that, the workpiece can be directly removed without the need for the staff to wash the workpiece, and the workpiece can be processed by the next process. An end plate 28 is fixedly mounted on one end of the first push plate 23, a second electric telescopic rod 72 is fixedly mounted on one of the end plates 28, and a U-shaped plate 71 is fixedly mounted on the movable end of the second electric telescopic rod 72, driving one of the first push plates 23 to move along the length direction of the working area, and making the U-shaped plate 71 located directly below the cleaning rod 51, and then the movable end of the second electric telescopic rod 72 extends, so that the cleaning rod 51 is located between the two vertical parts of the U-shaped plate 71, and then the first push plate 23 continues to move in the length direction of the working area, so as to push the cleaning rod 51 to slide along the slide rail 52;

[0072] Furthermore, different workpieces have different thicknesses, and to clean larger debris on the surface of the workpiece, the lower surface of the cleaning rod 51 needs to be in contact with the upper surface of the workpiece or the spacing is small. Slide rails 52 are slidably installed on the opposite surfaces of the two side panels 14. The two ends of the cleaning rod 51 in the length direction are slidably connected to the two slide rails 52 through sliders 512. Bolts 53 are threadedly connected to the side panels 14. The bottom ends of the bolts 53 are rotatably connected to the slide rails 52. By rotating the bolts 53, the slide rails 52 can slide on the side panels 14, and the cleaning rod 51 can be changed. The height at which it is located, and thus for workpieces of different thicknesses, the cleaning rod 51 can also clean up larger debris on the surface of the workpiece; a movable opening is set on one side surface of the frame 10, and a second slide bar 65 is set in the movable opening, and the first slide bar 102 is also fixedly installed on the movable opening, and a first slide sleeve 651 is fixedly installed on the end of the second slide bar 65, and the first slide sleeve 651 is slidably sleeved on the outer surface of the first slide bar 102, and a second slide sleeve 64 is fixedly installed on the outer surface of the conveying pipe 62, and the second slide sleeve 64 is slidably connected to the second slide bar 65.

[0073] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any form. Any ordinary technician in the industry can smoothly implement the present invention as shown in the drawings and described above. However, any equivalent changes, modifications and evolutions made by technicians familiar with the profession without departing from the scope of the technical solution of the present invention using the technical content disclosed above are all equivalent embodiments of the present invention.
