Description

Technical Field

[0001] The present invention relates to the technical field of machine tools, in particular to a three-spindle vertical and horizontal composite machining device. Background Art

[0002] The field of machine tool technology includes metal cutting machine tools, forging machine tools, woodworking machine tools and other material processing and forming equipment. The core is to realize workpiece cutting, grinding, boring, drilling and other processing through mechanical structure and power system. It covers the manufacturing of basic parts to complex precision components, involving key technologies such as structural design, transmission configuration, motion control, including whole machine precision design, cutting process optimization, dynamic performance regulation and high-precision component application. It is widely used in industrial fields such as automobile, aerospace, energy, etc., and is the basis for efficient and precise production in the manufacturing industry.

[0003] One of them is a three-spindle vertical and horizontal composite machining device, which refers to a machine tool with three spindles that can realize composite operation of vertical and horizontal machining modes. In order to solve the problem of multiple clamping times and low posture conversion efficiency in multi-process machining, a bed is set up to carry a rotary worktable and movable vertical first horizontal and second horizontal machining devices. Each device moves independently in the XYZ direction. Three tool magazines are configured to realize tool replacement. A chip removal device and an independent lubrication and pneumatic cooling system are equipped for each machining device to complete the machining.

After the workpiece is processed, debris and dust are easily left on the surface, requiring additional processes, increasing the process and reducing efficiency. It does not explain how to protect equipment components from debris, which may reduce operational stability. The movement of processing equipment and the flexibility of fixtures are not optimized, and the scope of application is limited when facing complex and multi-directional processing needs.

DETAILED DESCRIPTION

[0033] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0034] A three-spindle vertical and horizontal composite machining device, see Figure 1 、 Figure 2 and Figure 3 , including a base 1, a shell 2 is fixed on the upper end of the base 1, a control terminal 4 is provided at the front end of the shell 2, an electrical cabinet 3 is fixed on one side of the shell 2, cutting fluid and cleaning fluid are stored on the inside of the base 1, a three-spindle processing structure 5 for composite processing of the workpiece is provided on the right side of the inner cavity of the shell 2, a spray structure 7 for cleaning the workpiece is provided on the left side of the inner cavity of the shell 2, a discharge port 21 connected to the spray structure 7 is opened at the left end of the shell 2, and a material transfer structure 6 for transporting the workpiece from the shell 2 to the spray structure 7 is provided at the rear part of the inner cavity of the shell 2.

[0035] During the operation of this embodiment, the workpiece is processed by the three-spindle processing structure 5, and at the same time, the debris and dust generated by the processing of the workpiece are removed from the workpiece and the three-spindle processing structure 5, and further the workpiece is taken out from the three-spindle processing structure 5 and sent into the spray structure 7 by the action of the material transfer structure 6. The debris and dust on the surface of the workpiece are washed clean by the action of the spray structure 7 and sent out through the discharge port 21, thereby realizing the composite processing and post-processing comprehensive operation of the workpiece, improving the processing efficiency and reducing the processing flow.

[0036] Embodiment 2: Based on the embodiment 1, this embodiment utilizes the screw 1 512 of the longitudinal axis portion 51 in the three-spindle processing structure 5 to cooperate with the slider 1 511 to drive the vertical processing equipment 52 and the horizontal processing equipment 53 to move up and down, and cooperates with the sliding plate 541, the screw 2 544 and the screw 3 551 of the transverse axis portion 54 to drive the workpiece to move horizontally in multiple directions, thereby realizing vertical and horizontal composite processing and multi-directional processing, and improving the scope of application; the fixture seat 542 is adapted to a universal fixture, and the flexibility is improved by the rapid replacement of bolts, and the processing efficiency is guaranteed by combining CNC program control;

[0037] The isolation belt 1 514 of the longitudinal axis 51 and the isolation belt 2 554 of the bottom plate 55 are used to isolate processing debris to avoid affecting the operation of screw 1 512 and screw 3 551; the cleaning brush 5434 and the silicone scraper 543 of the cleaning part 54 of the horizontal axis 54 clean the debris, and the drainage pipe 552 and the isolation mesh cover 553 of the bottom plate 55 realize the reflux of cutting fluid and the separation of debris, which not only protects the stability of the equipment, but also realizes resource circulation and improves operational reliability.

[0038] For further information, see Figure 4 The three-spindle processing structure 5 includes a base plate 55 installed in the inner cavity of the shell 2. The upper end of the base plate 55 is symmetrically fixed with a longitudinal axis portion 51. The ends of the longitudinal axis portions 51 on both sides that are close to each other are respectively installed on the vertical processing equipment 52 for vertical processing and the horizontal processing equipment 53 for horizontal processing. The upper end of the base plate 55 is provided with a transverse axis portion 54 for mounting the workpiece.

[0039] The vertical processing equipment 52 and the horizontal processing equipment 53 are driven up and down by the longitudinal shaft parts 51 on both sides, and the workpiece is driven to different positions by the transverse shaft part 54, thereby realizing multi-directional processing of the workpiece. At the same time, the vertical processing equipment 52 and the horizontal processing equipment 53 are driven by the longitudinal shaft parts 51 respectively, realizing horizontal and vertical composite processing, thereby improving the scope of application.

[0040] Furthermore, it should be noted that the above-mentioned vertical processing equipment 52 and horizontal processing equipment 53 are both milling equipment used by conventional machine tools. Their processing surfaces are also provided with spray pipes connected to the inner side of the base 1 for supplying cutting fluid, which is convenient for spraying cutting fluid on the surface of the workpiece during the processing. In the present invention, they are only used to demonstrate the turning function effect, and their specific installation method and operation method will no longer be displayed or elaborated.

[0041] Furthermore, the installed transverse axis 54 can drive the workpiece to move in the horizontal direction, thereby cooperating with the functions of the longitudinal axis 51 on both sides so that the vertical processing equipment 52 and the horizontal processing equipment 53 can adapt to the processing requirements of different positions.

[0042] For further information, see Figure 4 The inner surface of the longitudinal axis 51 is rotatably connected to a screw 512 driven by a motor, and the inner surface of the longitudinal axis 51 is slidably connected to a slider 511 threadedly connected to the screw 512. The inner cavity of the longitudinal axis 51 is slidably connected to an isolation belt 514 in a ring shape and fixedly connected to the adjacent slider 511. The isolation belt 514 slides synchronously with the slider 511 to isolate the inner cavity of the longitudinal axis 51 from the outside. The end of the slider 511 close to the horizontal axis 54 is fixedly connected to a mounting seat 513, and the mounting seat 513 is used to install the vertical processing equipment 52 and the horizontal processing equipment 53.

[0043] The rotation of the screw 512 and the threaded action of the slider 511 drive the slider 511 to slide up and down in the longitudinal shaft portion 51. The vertical processing device 52 or the horizontal processing device 53 is further mounted on the mounting seat 513 provided on one side of the slider 511, thereby driving the vertical processing device 52 or the horizontal processing device 53 to move up and down, and processing is performed in accordance with the CNC program.

[0044] Simultaneously, the isolation zone 514 provided on the inner side of the longitudinal shaft portion 51 can isolate the debris generated during the turning process, thereby preventing the debris from splashing into the inner side of the longitudinal shaft portion 51 and affecting the operating stability of the screw 512 .

[0045] For further information, see Figure 5 and Figure 6The horizontal axis portion 54 includes a sliding plate 541 that is slidably connected to the upper end of the bottom plate 55, and a clamp seat 542 for installing a clamp is provided at the upper end of the sliding plate 541. The inner cavity of the clamp seat 542 is provided with a cleaning member 543 for cleaning debris at the upper end of the longitudinal axis portion 51. A sliding groove 545 that is slidably connected to the clamp seat 542 is provided at the upper end of the sliding plate 541. The inner surface of the sliding groove 545 is rotatably connected to a screw 2 544 driven by a motor. The screw 2 544 is threadedly connected to the lower end of the clamp seat 542. Connecting grooves 546 that are connected to the left and right ends of the sliding plate 541 are provided on the left and right sides of the inner surface of the sliding groove 545. Silicone scrapers that are in close contact with the upper end of the bottom plate 55 are installed on the front and back sides of the lower end of the sliding plate 541.

[0046] For further information, see Figure 5 , drainage pipes 552 connected to the base 1 for reflowing cutting fluid are provided on the front and back sides of the upper end of the bottom plate 55, and isolation mesh covers 553 are installed at the front and back corners of the bottom plate 55. The lower side of the isolation mesh cover 553 is connected to the drainage pipe 552. The inner surface of the bottom plate 55 is slidably connected to an isolation belt 2 554 fixedly connected to the lower end of the sliding plate 541. The inner cavity of the bottom plate 55 is symmetrically rotated with a screw 3 551 threadedly connected to the lower end of the sliding plate 541 driven by a motor.

[0047] The fixture base 542 is a universal mounting fastener that can be used with universal fixtures in existing equipment. Different fixtures can be quickly installed and replaced by bolts. Its use is conventional technology, and its specific structure and installation method will not be further demonstrated or described in detail in this invention.

[0048] Furthermore, the third screw 551 can drive the sliding plate 541 to slide back and forth on the upper end of the bottom plate 55, thereby driving the cleaning member 543 to process the debris on the upper end of the bottom plate 55. At the same time, the second isolation belt 554 can block the sliding path of the sliding plate 541, and has the same function as the first isolation belt 514, and can block the debris generated by processing.

[0049] Furthermore, under the action of the cleaning member 543, the cutting fluid and debris above the screw rod 551 will move to the front and rear sides under the dual action of the sliding plate 541 and the cleaning member 543. On this basis, the isolation mesh cover 553 on the front and rear sides of the base plate 55 can separate the debris and cutting fluid. The debris falls into the pre-opened grooves on the front and rear sides through the isolation mesh cover 553 for storage, while the cutting fluid will flow back to the base 1 through the drain pipe 552 of the same specifications for convenient recycling.

[0050] For further information, see Figure 6The cleaning member 543 includes a U-shaped plate 5431 installed at the lower end of the sliding plate 541, and the U-shaped plate 5431 slides left and right on the inner surface of the screw 2 544. The sliding plate 541 has through holes on both sides, and the through holes are fixedly connected to the open plate 5436 on both sides. The U-shaped plate 5431 is U-shaped, and the inner surfaces of the vertical parts on both sides are rotatably connected to the central shaft 5433. The outer surfaces of the two central shafts 5433 are symmetrically fixedly connected to the cleaning brushes 5434 that pass through the inner surface of the open plate 5436. The outer surfaces of the cleaning brushes 5434 on both sides are fitted with the upper ends of the adjacent bottom plates 55. The outer surfaces of the central shafts 5433 on both sides are jointly wound and connected with cables 5432. The middle part of the upper end of the bottom plate 55 is fixedly connected to the fixing seat 5435. The cable 5432 is fixedly connected to the fixing seat 5435. During the sliding process of the sliding plate 541, the cable 5432 drives the central shaft 5433 to rotate under the action of the slide groove 1 545.

[0051] First, under the action of screw 2 544, the fixture seat 542 can be driven to move left and right, thereby driving the fixture seat 542 and the fixture and workpiece above it to move toward one of the longitudinal axis parts 51, and through the cooperation of the CNC program, the workpiece above it is moved to be processed.

[0052] When the sliding plate 541 is moved back and forth by the action of the third screw 551, the fixing seat 5435 is fixed, which pulls the cable 5432 to keep its position relatively fixed. Then, when the U-shaped plate 5431 moves following the second screw 544, the position of the central shaft 5433 changes along with the U-shaped plate 5431. At this time, the cable 5432 wound around the outer surface of the central shaft 5433 will produce friction and sliding due to its relatively fixed position, thereby driving the central shaft 5433 to rotate, and synchronously driving the cleaning brush 5434 to rotate, thereby cleaning the debris on the sliding plate 541.

[0053] Furthermore, since the sliding plate 541 can move left and right, during the movement of the sliding plate 541, due to the limitation of the fixed seat 5435, the U-shaped plate 5431 cannot move left and right, but remains horizontally stationary in the reserved space at the bottom of the sliding plate 541. At this time, the position of the perforated plate 5436 relative to the U-shaped plate 5431 changes, and the positions of the side walls of the sliding plate 541 and the longitudinal axis 51 will also change relatively, thereby reducing the space that needs to be cleaned. The cleaning brush 5434 will be retracted into the inner side of the sliding plate 541 through the perforated plate 5436, and under the scraping action of the perforated plate 5436, the debris will be isolated on the outside of the sliding plate 541.

[0054] For further information, see Figure 7The lower end of the clamp seat 542 is fixedly connected to a slider 2 5421 which slides on the inner surface of the slide groove 1 545 and is threadedly connected to the screw 2 544. The left and right ends of the slider 2 5421 are symmetrically fixedly connected to the connecting cage 5422 which is sleeved on the outer surface of the screw 2 544. The two connecting cages 5422 are fixedly connected at one end away from the slider 2 5421 with a cleaning ring 5423 for cleaning the outer surface of the screw 2 544. The lower part of the outer surface of the two cleaning rings 5423 is fixedly connected to a scraper 5424 which fits the bottom wall of the slide groove 1 545.

[0055] When the fixture base 542 slides left and right on the sliding plate 541 under the action of the second screw 544, due to volume limitations, it is not possible to use a method similar to the isolation strips 1 514 and 2 554 to isolate debris. The second screw 544 will inevitably be contaminated with debris, thus requiring additional treatment.

[0056] When slider 2 5421 slides in slide groove 1 545 under the action of screw 2 544, the connecting cages 5422 on both sides will push the cleaning ring 5423 to move synchronously, and use the bristles on the inner wall of the cleaning ring 5423 to clean screw 2 544. Further, screw 2 544 will rotate. Although the cleaning ring 5423 cannot rotate, its relative displacement can still achieve the cleaning of the thread gap of screw 2 544. The synchronous scraper 5424 moves synchronously with the cleaning ring 5423, and can push the cleaned debris to the connecting groove 546, and finally discharge it through the connecting groove 546.

[0057] Example three. Based on Example two, this example further cooperates with the reciprocating screw 64 of the material transfer structure 6 and the limit frame 61 to drive the feeding part 62 to slide in the second slide 63. The bidirectional screw 625, the slider three 623 and the contact block 622 of the feeding part 62 are combined to realize the workpiece clamping and transfer, and switch between the three-spindle processing structure 5 and the spray structure 7; the water tank 71, the uniform water pipe 72 and the spray head 73 of the spray structure 7 flush the workpiece, and cooperate with the grid plate 74 to realize the circulation of the cleaning liquid, reduce the amount of chips carried by the workpiece, and reduce the post-processing process and environmental debris pollution.

[0058] For further information, see Figure 8 The material transfer structure 6 includes a second chute 63 fixedly connected to the rear portion of the inner surface of the shell 2, the inner surface of the second chute 63 is slidably connected to the limit frame 61, the inner surface of the limit frame 61 is rotatably connected to the feeding part 62 for taking and placing materials, the inner surface of the second chute 63 is rotatably connected to the reciprocating screw 64 threadedly connected to the inner surface of the feeding part 62 through a threaded ring, the reciprocating screw 64 is driven by a motor installed on the inner side of the second chute 63, the second chute 63 is in the shape of a Japanese character, and the openings on the left and right sides are respectively connected to the range where the three-spindle processing structure 5 and the spray structure 7 are located.

[0059] The reciprocating screw 64 can drive the feeding part 62 and the limiting frame 61 to slide left and right in the second chute 63. At the same time, due to the shape of the second chute 63, the feeding part 62 is restricted within the predetermined trajectory and cannot rotate. It can only slide in the second chute 63 following the limiting frame 61 under the action of the reciprocating screw 64, thereby realizing the switching between the spray structure 7 and the three-spindle processing structure 5.

[0060] Specifically, initially the feeding portion 62 is within the range of the spray structure 7, and the reciprocating screw 64 rotates forward. At this time, the rotation trend of the feeding portion 62 is to rotate backward, but due to the obstruction of the second chute 63, the feeding portion 62 can only slide to the right under the action of the reciprocating screw 64 until it enters the gap on the other side of the second chute 63. At this time, the reciprocating screw 64 reverses. Due to the lack of a limit, the feeding portion 62 will rotate with the reciprocating screw 64, and then switch from a vertical state to a horizontal state, and the workpiece is clamped and fixed by the action of the feeding portion 62;

[0061] Furthermore, the forward rotation of the reciprocating screw 64 drives the feeding portion 62 carrying the workpiece to a vertical state, and since the feeding portion 62 has reached the end of the right trajectory, the continued forward rotation of the reciprocating screw 64 will trigger movement to the left, thereby driving the feeding portion 62 to move to the left, resetting the feeding portion 62 so that it returns to the range of the spray structure 7, and driving the feeding portion 62 to a horizontal state through the reverse rotation of the reciprocating screw 64, so that the workpiece enters the water uniforming pipe 72 and the bottom of the spray head 73.

[0062] For further information, see Figure 9 The feeding part 62 includes a rectangular frame 621 rotatably connected to the inner surface of the limit frame 61, and contact blocks 622 are symmetrically arranged on the inner surface of the rectangular frame 621. The two contact blocks 622 are fixedly connected to the inner wall of the rectangular frame 621 on the left and right sides thereof. The two contact blocks 622 are fixedly connected to the inner wall of the rectangular frame 621 on the sides thereof away from each other through telescopic rods. The two contact blocks 622 are symmetrically rotatably connected to the connecting rod 624 on the sides thereof away from the contact blocks 622. The two connecting rods 624 on the same side are rotatably connected to a slider three 623 slidably connected to the inner wall of the rectangular frame 621 on the sides thereof away from the contact blocks 622. The inner surfaces of the two slider three 623 on the same side are commonly threadedly connected to a bidirectional screw 625, which is driven by a motor installed on the inner side of the rectangular frame 621. Arc grooves 626 for limiting the rotation angle thereof are symmetrically opened on the left and right ends of the rectangular frame 621. The rectangular frame 621 can only rotate forward 90 degrees under the restriction of the arc groove 626.

[0063] The bidirectional screw 625 can drive the slider 3 623 to slide on the inner surface of the rectangular frame 621, and the sliding tendency is to move closer to each other or away from each other. When the slider 3 623 moves closer to each other, the pushing action of the connecting rod 624 and the limiting action of the telescopic rod will push the contact block 622 toward the center of the rectangular frame 621, thereby clamping the workpiece.

[0064] When the sliders 3 623 move away from each other, the contact block 622 is pulled toward the inner wall of the rectangular frame 621 due to the pulling action of the connecting rod 624 and the limiting action of the telescopic rod, thereby loosening the workpiece.

[0065] Simultaneously, the arc-shaped grooves 626 provided on both sides of the rectangular frame 621 can limit the rotation angle of the rectangular frame 621 .

[0066] For further information, see Figure 10 The spray structure 7 includes a water tank 71 installed on the inner surface of the outer shell 2, and clean water is stored in the water tank 71. A plurality of water-distributing pipes 72 connected to the water pump installed inside the water tank 71 are fixedly connected in an array on the upper rear end of the water tank 71, and a plurality of spray heads 73 are installed in an array on the lower outer surfaces of the plurality of water-distributing pipes 72. A mesh plate 74 is fixedly connected to the lower part of the inner surface of the outer shell 2 located below the spray head 73, and the bottom of the mesh plate 74 is connected to the cleaning liquid circulation box inside the base 1. The upper side of the mesh plate 74 is a slope and its bottom is connected to the discharge port 21.

[0067] The cleaning liquid is transported to the water distribution pipe 72 and the spray head 73 through the water pump installed in the water tank 71, and then sprayed on the workpiece in the feeding part 62 to wash away the debris on the surface of the workpiece, thereby reducing the debris carried by the workpiece output, reducing the post-processing process and thus reducing the debris spillage in the production environment.
