Figure 2 is the second schematic structural diagram of the flexible automatic door provided by the embodiments of the present utility model (the opening is in the closed state). Figure 3 is one of the schematic structural diagrams of the flexible automatic door provided by the embodiments of the present utility model (the opening is in the open state). Figure 4 is the second schematic structural diagram of the flexible automatic door provided by the embodiments of the present utility model (the opening is in the open state).

[0045] Refer to Figures 1 to 4 As shown in, the embodiments of the present utility model provide a flexible automatic door 400, which includes a door frame 10, a flexible door body 20, a guiding component 30, and a driving component 40.

[0046] The door frame 10 is a quadrilateral structure formed by welding sheet metal parts, and a rectangular opening 16 is provided on the door frame 10.

[0047] The flexible door body 20 is movably arranged in the opening 16. One side of the flexible door body 20 is connected to the door frame 10, and the other side of the flexible door body 20 is set as the movable side. One side and the other side of the flexible door body 20 are arranged oppositely.

[0048] The guiding component 30 includes a guiding member 31 and a cooperating member 32. The cooperating member 32 is movably engaged with the guiding member 31. The guiding member 31 is arranged on the door frame 10, and the cooperating member 32 is arranged on the flexible door body 20. Among them, the guiding member 31 can be a guide rail or a track, and the cooperating member 32 can be a slider that cooperates with the guide rail, or the cooperating member 32 can also be a roller that cooperates with the track.

[0049] The driving component 40 is fixedly arranged on the door frame 10 through a mounting structure such as a support. The driving component 40 includes structures such as a cylinder, an electric cylinder or a hydraulic cylinder. The driving end of the driving component 40 is connected to the movable end of the flexible door body 20, and is used to drive the flexible door body 20 to perform linear reciprocating motion along the guiding member 31 to open or close the opening 16.

[0050] It can be understood that for the flexible automatic door 400 provided by the embodiment of the present utility model, by providing the opening 16 on the door frame 10, the flexible door body 20 is movably arranged in the opening 16. The flexible door body 20 is movably engaged with the door frame 10 through the guiding component 30. The driving end of the driving component 40 is connected to the movable end of the flexible door body 20, and is used to drive the flexible door body 20 to perform linear reciprocating motion along the guiding member 31 to open or close the opening 16. With such a setting, the flexible automatic door 400 can be designed as a structure independent of the vertical machining center, and can be centrally assembled and mass-produced offline, without being affected by the protective cover of the vertical machining center and the production cycle of the machine body 100, and can effectively improve the manufacturing and assembly efficiency of the vertical machining center.

[0051] Since the relevant parts of the traditional automatic door are all scattered on the protective cover of the machine body 100, the assembly of the automatic door must wait until the protective cover of the machine body 100 is completed, and it is impossible to carry out the assembly of the automatic door and the assembly of the protective cover of the machine body 100 in parallel, which prolongs the production cycle of the machine tool. At the same time, the relevant parts of the traditional automatic door are relatively scattered, which requires a large installation site, is very inconvenient to operate, and it is not easy to guarantee the assembly accuracy, and it is easy to cause large running noise or poor sealing performance of the automatic door due to the assembly experience of workers.

[0052] The flexible automatic door 400 provided by the embodiment of the present utility model can be centrally assembled and mass-produced offline by designing the flexible automatic door 400 as a structure independent of the vertical machining center. It is not affected by the production cycle of the protective cover of the vertical machining center and the fuselage 100, and can effectively improve the manufacturing and assembly efficiency of the vertical machining center, and is easy to install.

[0053] Refer to Figures 1 to 4 , in some embodiments of the present utility model, the flexible door body 20 includes a flexible armor door body and a rigid follower 70. One side of the armor door body is connected to the door frame 10, and the other side of the armor door body is connected to the follower 70; the follower 70 is connected to the mating part 32, and the driving end of the driving component 40 is connected to the follower 70.

[0054] Among them, the flexible armor door body is made by sequentially connecting stainless steel sheets, and can withstand impacts and high temperatures above 900 °C caused by hot fragments. And the flexible armor door body has good adhesion and can resist dust, sand and iron filings, etc.

[0055] Since the flexible armor door body cannot withstand the driving action of the driving component 40, a follower 70 is connected to the movable side of the armor door body by welding or sealing connection. The follower 70 can be a structure such as a steel plate, which can withstand a certain load and torque. The driving end of the driving component 40 is connected to the follower 70, and the entire armor door body is driven by the follower 70 to move synchronously to open or close the door body.

[0056] Continue to refer to Figure 1 and Figure 3 , in some embodiments of the present utility model, the flexible automatic door 400 further includes a scissor mechanism 50 and a driving member 60. One end of the scissor mechanism 50 is hinged to the fixed side of the flexible door body 20, and the other end of the scissor mechanism 50 is hinged to the movable side of the flexible door body 20.

[0057] The driving member 60 is arranged in the middle of the flexible door body 20. The middle position of the scissor mechanism 50 is hinged to the driving member 60, and the driving end of the driving component 40 is connected to the driving member 60.

[0058] The scissor mechanism 50 includes a plurality of cross-set connecting rod assemblies, and two adjacent connecting rod assemblies are hinged. Equivalently, the scissor mechanism 50 is a superposition of planar connecting rod mechanisms, and the expansion and contraction are realized by the angle change of the connecting rod mechanism. When the flexible automatic door 400 is closed, two adjacent connecting rods of the scissor mechanism 50 move away from each other to expand. When the flexible automatic door 400 is opened, two adjacent connecting rods of the scissor mechanism 50 move closer to or overlap with each other to contract.

[0059] Since the flexible automatic door 400 adopts a scissor mechanism 50, the scissor arms can cooperate with each other, thereby increasing the stability of the flexible door body 20 during the opening or closing process, making the flexible door body 20 operate more smoothly and safely. In addition, an active member 60 is arranged at the middle position of the flexible door body 20, the middle position of the scissor mechanism 50 is hinged to the active member 60, and the driving end of the driving component 40 is connected to the active member 60, which is used to drive the active member 60 to move along the guide member 31 to drive the flexible door body 20 to open or close the opening 16. Such a setting can not only improve the opening or closing speed of the flexible door body 20, that is, achieve speed increase, but also shorten the stroke and design size of the driving component 40 such as a cylinder, thereby optimizing the space occupancy rate of the driving component 40.

[0060] Among them, the driving component 40 can be driven by a hydraulic system to quickly open or close the flexible door body 20 and improve the efficiency of opening and closing the door.

[0061] Equivalently, the flexible automatic door 400 provided by the embodiment of the present invention uses the active member 60 at the middle position as the driving end or trigger end. When the driving component 40 drives the active member 60 to move, the active member 60 drives the flexible automatic door 400 to open or close through the scissor mechanism 50.

[0062] Continue to refer to Figure 1 and Figure 3 , in some embodiments of the present invention, the guide members 31 are arranged at intervals along the width direction of the door frame 10 and are located on both sides of the opening 16. Two cooperating members 32 are slidably arranged on each guide member 31; the active member 60 is fixed on one of the cooperating members 32, and the movable side of the flexible door body 20 is fixed on the other cooperating member 32.

[0063] Equivalently, the flexible automatic door 400 provided by the embodiment of the present invention is provided with guide members 31 on both the upper and lower sides of the opening 16, and two cooperating members 32 are arranged on each guide member 31. The two cooperating members 32 are respectively used to fix the driven member 70 and the active member 60, so that the driven member 70 and the active member 60 both slide along the guide member 31 to improve the stability of the flexible automatic door 400.

[0064] In some embodiments of the present invention, the flexible automatic door 400 further includes a position detection component, and the position detection component is arranged on the driving component 40 or the door frame 10, and is used to detect the position information of the flexible door body 20, so as to determine whether the flexible automatic door 400 is fully opened or fully closed according to the position information of the flexible door body 20, further improving the reliability of the flexible automatic door 400.

[0065] Among them, when the position detection component is arranged on the driving component 40, the position detection component includes a magnetostrictive displacement sensor. The magnetostrictive displacement sensor is arranged inside or outside the driving component 40, and is used to detect the displacement of the driving component 40.

[0066] For example, when the driving component 40 is a hydraulic cylinder or a pneumatic cylinder, by arranging a magnetostrictive displacement sensor on the driving component 40 to measure the position of the piston of the driving component 40, the position of the driving component 40 can be accurately and reliably feedback, and it can be determined whether the flexible automatic door 400 is fully opened or fully closed, further improving the reliability of the flexible automatic door 400.

[0067] When the displacement sensor is a magnetostrictive displacement sensor, there are two different installation methods of the magnetostrictive displacement sensor on the hydraulic cylinder or the pneumatic cylinder, namely, the built-in type and the external type.

[0068] When the magnetostrictive displacement sensor is installed externally, it is usually installed at the earring of the piston rod of the hydraulic cylinder or the pneumatic cylinder. When the magnetostrictive displacement sensor is installed internally, the magnetostrictive displacement sensor is located inside the hydraulic cylinder or the pneumatic cylinder. The specific installation method can be determined according to the actual use situation.

[0069] In addition to the above magnetostrictive displacement sensor, the displacement sensor can also be other displacement sensors, such as a laser displacement sensor, etc., as long as it can realize displacement detection.

[0070] Continue to refer to Figures 1 to 4 , in some embodiments of the present invention, the door frame 10 includes a bottom plate 11, two side plates and a panel 15. The bottom plate 11 is connected to the bottom of the panel 15, and an acute angle is formed between the bottom plate 11 and the panel 15. The two side plates are the first side plate 13 and the second side plate 14 respectively. The first side plate 13 and the second side plate 14 are connected to both sides of the panel 15, and an opening 16 is provided on the panel 15.

[0071] When the door frame 10 is installed flush with the bottom of the machine body 100, the panel 15 and the flexible door body 20 installed at the opening 16 of the panel 15 are inclined relative to the protective cover side plate of the machine body 100. That is, the bottom plate 11 of the flexible automatic door 400 is connected to the machine body 100, the top plate 12 of the flexible automatic door 400 is connected to the inner wall of the protective cover of the machine body 100, and the side plates (i.e., the first side plate 13 and the second side plate 14) on the left and right sides of the flexible automatic door 400 are flush with the inner side of the right column protective sheet metal of the machine tool. The flexible automatic door 400 is designed in an inclined style from top to bottom and is integrally installed in front of the right column protective sheet metal. This setting can ensure that the chips falling on the flexible door body 20 and the panel 15 of the flexible automatic door 400 can smoothly fall onto the flowing water surface of the machine body 100. The chips falling on the flowing water surface of the machine body 100 can be discharged into the chip discharge groove in front of the machine body 100 through the flushing device inside the machine, and the discharging mechanism 600 discharges them outside the machine tool.

[0072] Further, in order to improve the sealing performance of the door frame 10, the door frame 10 further includes a top plate 12 and a baffle 17. The top plate 12 is connected to the top of the panel 15. The top plate 12, the two side plates, and the bottom plate 11 enclose a frame structure. By connecting the top plate 12, the two side plates, and the bottom plate 11 to the corresponding parts of the machine tool respectively, it is equivalent to that the four borders of the door frame 10 all have extended structures, and this extended structure can coincide with the corresponding parts of the machine tool, thereby improving the sealing performance at the connection between the door frame 10 and the machine tool.

[0073] In addition, the baffle 17 is arranged at the upper edge of the opening 16. Through this baffle 17, it can effectively block the chips and cutting fluid falling on the flexible door body 20 and the panel 15 of the flexible automatic door 400, and avoid the chips and cutting fluid from spraying on the upper side of the door frame 10.

[0074] Continue to refer to Figure 1 and Figure 3 , in some embodiments of the present invention, the flexible automatic door 400 further includes a drag chain 80. One end of the drag chain 80 is fixed to the bottom plate 11 of the door frame 10, and the other end of the drag chain 80 is arranged on the movable side of the flexible door body 20 and is adapted to move with the flexible door body 20. The lubrication pipelines of the guide member 31 and the mating member 32 are both arranged in the drag chain 80.

[0075] The lubrication pipelines of the guide rail and the slider enter the lubrication pump of the machine tool through the drag chain 80 to achieve automatic lubrication. The movable end of the drag chain 80 is connected to the connecting plate of the slider through the drag chain 80 bracket, the fixed end of the drag chain 80 is connected to the bottom plate 11 of the door frame 10, and the lubricating oil pipe of the slider enters the drag chain 80 together with the driven member 70.

[0076] The flexible automatic door 400 provided by the embodiment of the present utility model has the fixed side of the armored door body connected to the door frame 10, the movable side of the armored door body is connected to the driven member 70, the air cylinder is installed on the door frame 10 through an air cylinder bracket, the air cylinder rod is supported by an air cylinder rod support, and the driving end of the air cylinder is connected to one of the sliders through a connecting plate. The scissor mechanism 50 has three installation positions, which are respectively on the driven member 70, the driving member 60 and the door frame 10.

[0077] When the flexible automatic door 400 needs to be opened, the air cylinder rod drives the driving member 60 to move through the slider connecting plate, so that the driving member 60 drives the slider to perform a linear motion along the guide rail, and at the same time drives the scissor mechanism 50 to move in the pushing direction of the air cylinder rod. The scissor mechanism 50 drives the driven member 70 to move synchronously to open the flexible automatic door 400. When the air cylinder rod is fully pushed out, the magnetic switch indicating that the air cylinder rod is pushed in place emits a signal in place, and the system determines that the flexible automatic door 400 is fully opened.

[0078] When the flexible automatic door 400 needs to be closed, the air cylinder rod retracts, drives the driving member 60 to move through the slider connecting plate, so that the driving member 60 drives the slider to perform a linear motion along the guide rail, and at the same time drives the scissor mechanism 50 to move in the retracting direction of the air cylinder rod. The scissor mechanism 50 drives the driven member 70 to move synchronously to close the flexible automatic door 400. When the air cylinder rod is fully retracted into the air cylinder, a signal indicating that the door is closed in place is emitted, and the system determines that the flexible automatic door 400 is fully closed.

[0079] Figure 5 It is a schematic structural diagram of a vertical machining center provided by the embodiment of the present utility model. Figure 6 It is a partial structural schematic diagram of a vertical machining center provided by the embodiment of the present utility model.

[0080] Refer to Figure 5 and Figure 6 The embodiment of the present utility model further provides a vertical machining center, which includes a machine body 100, a workbench 200, a spindle box 300 and the flexible automatic door 400 according to any one of the above, provided on the machine body 100. The workbench 200 is arranged on the sliding seat of the machine body 100, and the spindle box 300 is located above the workbench 200; the flexible automatic door 400 is inclined and arranged on the side of the machine body 100, and the opening direction of the flexible automatic door 400 is set along the direction away from the workbench 200.

[0081] When the doorframe 10 is installed flush with the bottom of the machine body 100, the flexible automatic door 400 is designed in an inclined style from top to bottom and is integrally installed in front of the protective sheet metal of the right column. With this setting, it can ensure that the chips falling on the flexible door body 20 and the panel 15 of the flexible automatic door 400 can smoothly fall onto the flowing water surface of the machine body 100. The chips falling on the flowing water surface of the machine body 100 can be discharged into the chip discharge groove of the machine body 100 in front of the machine body 100 through the flushing device inside the machine, and the discharging mechanism 600 discharges them outside the machine tool. The baffle 17 can prevent the chips from continuing to fall upward onto the flexible door body 20 of the flexible automatic door 400.

[0082] In addition, an operation and maintenance door is provided on the front of the machine body 100. Generally, the operation and maintenance door requires a spacious space and the operation and maintenance personnel face the long stroke direction of the machine tool. When the vertical machining center performs automatic loading and unloading processing, the front door is selected as the operation and maintenance door, and the flexible automatic door 400 required for automatic loading and unloading is set on the right side. The two doors are independently set and will not interfere with each other, which is convenient for the operation and maintenance of the machine tool and improves the safety of personnel.

[0083] Figure 7 It is one of the side views of the vertical machining center provided by the embodiment of the present invention. Figure 8 It is the second side view of the vertical machining center provided by the embodiment of the present invention.

[0084] Refer to Figure 7 and Figure 8 In some embodiments of the present invention, the opening direction of the flexible automatic door 400 is set along the direction away from the workbench 200, which can enable the workpiece to be machined to be clamped at any position in the front, middle, and rear of the workbench 200, facilitating the machining of the machine tool.

[0085] Equivalently, with this setting, the opening 16 position of the flexible automatic door 400 covers the full stroke movement range of the workbench 200. The workpiece can regularly change the clamping position on the workbench 200, avoiding concentrated wear of precision parts such as lead screws and guide rails in the transmission system.

[0086] Since the automatic door currently provided on the side of the machine tool for material loading and unloading is parallel to the Z-axis of the machine tool, the movement direction of the automatic door is up and down movement or front and back movement. After the automatic door is fully opened, the opening 16 position is both off-center and small, and does not cover the full stroke movement range of the workbench 200. The workpiece can only be clamped at a certain fixed position on the workbench 200, which is likely to cause concentrated wear of precision parts such as lead screws and guide rails.

[0087] In the embodiment of the present utility model, a flexible armor door body is adopted. After the flexible automatic door 400 is fully opened, the armor door bodies overlap each other, which can ensure that the flexible automatic door 400 has a relatively large opening space of 16. Moreover, the opening direction of the flexible automatic door 400 is set along the direction away from the workbench 200. With this setting, the position of the opening 16 can cover the full stroke movement range of the workbench 200, and the workpiece can be clamped at different positions of the workbench 200. The clamping position is flexible and variable, which can avoid the concentrated wear of precision parts such as lead screws and guide rails.

[0088] Due to the adoption of the flexible automatic door 400 in the embodiment of the present utility model, the position of the opening 16 covers the full stroke movement range of the workbench 200, and the workpiece can be clamped at different positions of the workbench 200. That is, after the flexible automatic door 400 is fully opened, the workpiece can be clamped on the fixture at the first position, as Figure 7 shown. By controlling the movement of the workbench 200 along the Y-axis direction to realize the switching of the machining position, the workpiece can also be clamped on the fixture at the second position, so as to realize the clamping of the workpiece at different positions of the workbench 200, and avoid the concentrated wear of precision parts such as lead screws and guide rails.

[0089] Figure 9 FIG. is a schematic structural diagram of a vertical machining center and a feeding device 700 provided by an embodiment of the present utility model.

[0090] Refer to Figure 9 , for the vertical machining center provided by the embodiment of the present utility model, the vertical machining center further includes a feeding device 700, and the feeding device 700 is arranged on one side of the flexible automatic door 400.

[0091] When the vertical machining center provided by the embodiment of the present utility model performs automatic loading and unloading, after editing the machining program and the automatic loading and unloading program of the part through the numerical control operation console, close the front door (i.e., the operation and maintenance door) and the flexible automatic door 400 of the vertical machining center, and the vertical machining center starts to machine the workpiece. After machining is completed, the flexible automatic door 400 automatically opens, the robotic arm of the feeding device 700 enters the machining area of the vertical machining center to pick up the workpiece, places it in the magazine of the feeding device 700, and then uses the robotic arm to place the blank in the magazine into the machining position of the workbench 200 of the vertical machining center. The robotic arm withdraws from the machining area, the flexible automatic door 400 closes, and the machine tool starts to machine another workpiece.

[0092] When it comes to the first-piece debugging of the workpiece or replacing the workpiece of a new model, open the front door (i.e., the operation and maintenance door) of the vertical machining center, and after debugging is completed, close the front door of the vertical machining center to start machining.

[0093] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features; and these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the various embodiments of the present invention.
