DETAILED DESCRIPTION

[0055] It should be understood that the embodiments of the application shown in the example embodiments are only illustrative. Although only a few embodiments of the application are described in detail herein, those skilled in the art will readily appreciate that many modifications are possible in the example embodiments without materially departing from the teachings and advantages of the subject matter recited. Accordingly, all such variations are intended to be included within the scope of the application. Other substitutions, modifications, changes and omissions can be made in the design, operating conditions and parameters of the example embodiments herein without departing from the spirit of the present application.

[0056] The embodiment of the present application provides a liftable opening and closing type material frame, which comprises:

[0057] Two material boxes 1, each material box 1 is a cuboid structure, the material box 1 is welded by steel frame, prevents the part from falling out. The four sides of each material box 1 are surrounded by three sides, and the other side has an opening; the openings of the two material boxes 1 are oppositely arranged; the upper parts of the two material boxes 1 are rotatably connected around a horizontal axis, the two material boxes 1 have a first state ( Figure 1 ) and a second state ( Figure 2 ); when the two material boxes 1 are in the first state, the opening ends of the two material boxes 1 abut, so that the interiors of the two material boxes 1 jointly form a storage space; when the two material boxes 1 are in the second state, the lower ends of the two material boxes 1 are separated from each other; specifically, the state of the two material boxes 1 can be adjusted by controlling one end of the two material boxes 1 to be lifted upward and controlling the other end of the two material boxes 1 to be lifted upward.

[0058] A hook and lock mechanism 50 is arranged to lock the two material boxes 1 when the two material boxes 1 are in the first state, preventing the two material boxes 1 from being separated when loading the parts 2.

[0059] Two bracket mechanisms 27, each bracket mechanism 27 is arranged in one material box 1 and is used to carry the parts 2, and the bracket mechanism 27 is movably arranged up and down along the material box 1;

[0060] Two lifting mechanisms 49, each lifting mechanism 49 is arranged below one bracket mechanism 27 and is used to control the movement of the bracket mechanism 27.

[0061] When the two material boxes 1 are in the first state and are loaded into the material frame, the lifting mechanism 49 controls the bracket mechanism 27 to be in the highest position. Then, the parts 2 are translated from the workbench to the bracket mechanism 27 by external force. After placing a layer of parts 2, the lifting mechanism 49 controls the bracket mechanism 27 to be lowered to an appropriate height, and the next layer of parts 2 is continuously laid, until the bracket mechanism 27 is lowered to the lowest position.

[0062] When the material box 1 is filled with parts 2, the entire device is transferred, and then the lifting mechanism 49 controls the bracket mechanism 27 to carry the parts 2 to rise, when the parts 2 rise to the upper edge of the material box 1 and are flush with the workbench, the parts 2 can be translated to the workbench. When the uppermost layer of parts 2 is moved away from the material box 1, the bracket mechanism 27 is continuously raised to a predetermined height by the lifting mechanism 49, and the next layer of parts 2 is stacked on the previous layer of parts.

[0063] When it is needed to adjust the two bins 1 to the second state, the restriction of the hook locking mechanism 50 is released first, the upper part of the end of the two bins 1 away from each other is pulled by the lifting sling, the two bins 1 can be rotated and separated around the reference horizontal axis, the storage space is opened, and the parts 2 in the storage space are poured out. After the parts 2 are unloaded, the upper part of the end of the two bins 1 close to each other is pulled by the lifting sling, the two bins 1 can be rotated and closed, and the first state is restored, and the two bins 1 are locked by the hook locking mechanism 50.

[0064] Compared with the prior art, the parts 2 can be poured out from the bottom of the bin 1, and can also be loaded and unloaded from the upper end of the bin 1. Different loading and unloading modes can be selected according to the properties such as the damage degree of the parts 2. The entire loading and unloading process of the parts 2 in the bin 1 can be completely subjected to static load. The painted parts, low-hardness parts, easily-deformed parts and high-precision parts will not be damaged by impact force during loading and unloading. The parts 2 loaded in the bin 1 can be lifted from the bottom of the bin to the top of the bin, and then directly translated to the workbench. Conversely, the parts 2 on the workbench can also be directly translated into the bin 1. During the loading, unloading or neat arrangement of the parts 2, the operator does not need to perform actions such as bending, squatting and drilling into the bin 1, and the operation process is convenient, fast, labor-saving and efficient.

[0065] In some embodiments, as shown in Figure 4 The bottom of each bin 1 is fixedly installed with a main beam 3, the main beam 3 is perpendicular to the rotation axis of the bin 1, two auxiliary beams 4 are vertically installed on both sides of the main beam 3, two side beams 5 are vertically installed on both sides of the end of each auxiliary beam 4, a reinforcing rib 6 for enhancing the connection reliability is arranged at the connecting corner of the auxiliary beam 4 and the main beam 3, and the bin 1 is installed on the two side beams 5. The inside of the main beam 3 is provided with an installation slot penetrating through both ends of the main beam 3; as Figures 5 to 9As shown, the hook and lock mechanism 50 comprises a hook body 7, a first fixed block 8, a second fixed block 9, a lever arm 10, a hook tongue 11 and a handle 12. The hook body 7 and the first fixed block 8 are fixedly installed in the installation slots of the two main beams 3 respectively, and are located at the end of the two main beams 3 close to each other; the second fixed block 9 is fixedly installed with the first fixed block 8 in the installation slot of the same main beam 3, and the first fixed block 8 and the second fixed block 9 are both provided with through holes; the lever arm 10 is slidably and rotatably penetrated through the through hole of the second fixed block 9, the hook tongue 11 is fixedly installed at one end of the lever arm 10, and the hook tongue 11 is slidably and rotatably penetrated through the through hole of the first fixed block 8; the handle 12 is installed on the lever arm 10 and is located at the end of the lever arm 10 extending out of the installation slot, and the linear motion and the rotary motion of the control handle 12 are transmitted to the hook tongue 11 through the lever arm 10, so that the hook tongue 11 can enter and exit the hook body 7 and be hung in the inside of the hook body 7, thereby realizing the actions of unlocking and locking. Specifically, the hook body 7 is provided with a clamping groove, and the hook tongue 11 can be resisted by the groove wall of the clamping groove after entering the clamping groove, the hook and lock mechanism 50 further comprises a stop block 13, the stop block 13 is assembled with the hook tongue 11 through a threaded pair, and is located between the first fixed block 8 and the lever arm 10, so as to control the linear motion stroke of the hook tongue 11, and after the hook tongue 11 moves to abut against the first fixed block 8, the rotation of the lever arm 10 is started.

[0066] In some embodiments, as Figures 11 to 14As shown, the lifting mechanism 49 includes the slide 14, the connecting plate 15, the fixed block 16, the lead screw 18 and the sliding block 19; the slide 14 is mounted on the main beam 3, specifically, the lower part of the slide 14 is coupled with the upper part of the main beam 3 by bolt and nut fastening, welding or riveting, etc. The slide 14 has an upward opening sliding groove, the fixed block 16 has two, and the two fixed blocks 16 are respectively arranged at the two ends of the slide 14, which can be installed and fixed on the slide 14 by welding or bolt fastening, etc. The connecting plate 15 is fixedly connected with the two fixed blocks 16, specifically, the middle part of the fixed block 16 is provided with a vertical clamping groove, and the end of the connecting plate 15 is inserted into the vertical clamping groove, which can be connected together by welding during assembly. The connecting plate 15 divides the sliding groove into a first sliding groove and a second sliding groove, the sliding block 19 has two, and the two sliding blocks 19 are respectively slidably arranged along the first sliding groove and the second sliding groove. The fixed block 16 has two positioning holes 161, the lead screw 18 has two, each lead screw 18 is in screw transmission cooperation with a sliding block 19, and the lead screw 18 and the sliding block 19 form a screw pair. One end of each lead screw 18 is rotatably inserted into one positioning hole 161 of the fixed block 16, the other end of the lead screw 18 is assembled with the fixed cone sleeve 53 through the conical surface cooperation, and is inserted into the positioning hole 161 of the other fixed block 16, so that the lead screw 18 and the fixed block 16 form a rotating pair, so that the lead screw 18 can only freely rotate in the positioning hole 161 of the fixed block 16 and cannot translate. The rotation of the lead screw 18 will drive the sliding block 19 to make a reciprocating linear motion in the slide 14; each lead screw 18 has a transmission gear 17 fixedly installed at the position outside the slide 14, specifically, the transmission gear 17 and the lead screw 18 are connected and fixed together through the transmission key 52 and the fastening nut 55, and can synchronously rotate, the two lead screws 18 are meshed through the transmission gears 17 installed at the two ends, and form a gear pair, the rotation of one transmission gear 17 will drive the rotation of the other transmission gear 17, the transmission ratio between the transmission gears 17 is 1:1, and the turning directions are opposite, so that the two sliding blocks 19 are synchronously close to or synchronously away from each other when the transmission gears 17 rotate.

[0067] Each bracket mechanism 27 is mounted with two pads 20. The lifting mechanism 49 also includes two connecting rods 21, which are arranged crosswise. One end of each connecting rod 21 is pivotally connected to a slider 19, and the other end of each connecting rod 21 is pivotally connected to the pad 20. The slider 19 is provided with a first connecting seat, and the lower portion of the pad 20 is provided with a second connecting seat. The connecting rods 21 are connected to the first and second connecting seats by a pin, or a hinge formed by bolts or nuts. Specifically, the lower ends of the connecting rods 21 are provided with arcuate grooves on both sides of the first connecting seat. The lower ends of the connecting rods 21 are semicircular and engage in the grooves on the slider 19, allowing free rotation about the axis of the slider pin 59 and preventing them from leaving the grooves on the slider 19. The other ends of the connecting rods 21 are forked. A groove is provided in the lower center portion of the pad 20. The forked head and pad 20 are connected by a bracket pin 51 or bolts and nuts, and engage in the grooves below the pad 20, forming a hinge. As the two sliders 19 perform linear motion in the first chute or the second chute respectively, the connecting rod 21 is driven to move, and the projection size of the connecting rod 21 in the height direction is changed, thereby causing the pad 20 to rise and fall.

[0068] Most of the lifting mechanisms in the prior art are shear-type lifting mechanisms, and a hydraulic or electric power device is attached to the shear-type lifting mechanism to provide power for the lifting mechanism, and the power device will move with the lifting mechanism. Since the shear-type lifting mechanism needs to be installed with slides on the upper and lower parts, the upper slide is prone to bending and deformation during the load-bearing process, causing lifting failures; the accompanying hydraulic and electric drive devices are large in size and occupy the loading space in the material frame. The present invention, by providing a slide 14, a connecting plate 15, a fixed block 16, a screw 18, a slider 19 and a transmission gear 17, can achieve that the lifting mechanism drive pad 20 is fixed and placed flat on the bottom of the bracket mechanism 27, and will not move relative to the bracket mechanism 27, thereby saving space and making the operation more stable.

[0069] In some embodiments, as Figure 15 and Figure 16 As shown, in the two lifting mechanisms 49, a transmission recess 22 is installed at one end of a screw 18 of one lifting mechanism 49, and the transmission recess 22 is connected to the screw 18 by a countersunk screw 54. A transmission protrusion 23 is installed at one end of a screw 18 of the other lifting mechanism 49. When the two material boxes 1 are in the first state, the transmission protrusion 23 is inserted into the transmission recess 22 to realize the synchronous rotation connection of the two screws 18. The screws 18 of the two lifting mechanisms 49 can transmit torque to each other through the engagement of the transmission protrusion 23 and the transmission recess 22. Therefore, by rotating only one of the screws 18, the two lifting mechanisms 49 can be started synchronously.

[0070] In some embodiments, the liftable and openable material frame further comprises a driving mechanism configured to provide power for the rotation of the lead screw 18. The driving mechanism can be a bidirectional ratchet wrench 24 and a wheel 25, which are arranged on one lead screw 18 of the two lifting mechanisms 49. The bidirectional ratchet wrench 24 and the wheel 25 can provide torque for the lead screw 18 by rotating the wheel 25 or the bidirectional ratchet wrench 24. Specifically, as shown in Figure 27 the end of the lead screw 18 is provided with a multi-angle fixing part 61 matched with the bidirectional ratchet wrench 24 and the wheel 25 through a screw 60. When in use, the wheel 25 or the bidirectional ratchet wrench 24 is sleeved outside the multi-angle fixing part 60 to prevent the wheel 25 or the bidirectional ratchet wrench 24 from slipping. As shown in Figure 28 the bidirectional ratchet wrench 24 has a wrench rod part 58, and the bidirectional ratchet wrench 24 can be fixed on the material box 1 through the elastic clamping spring 26 when not in use. In addition, the driving mechanism can also be driven by a motor, as long as it can transmit torque to the lead screw 18. The bidirectional ratchet wrench 24 can provide a large torque for the lead screw 18 of the lifting mechanism 49. At the same time, under the action of the screw pair, the lead screw 18 of the lifting mechanism 49 provides a large driving force for the sliding block 19 and the connecting rod 21. Therefore, the operator can lift a very heavy part 2 with very small force.

[0071] In some embodiments, as shown in Figure 3 the liftable and openable material frame further comprises a plurality of elastic power assisting mechanisms 28 arranged below the bracket mechanism 27. The elastic power assisting mechanisms 28 are configured to convert the gravitational potential energy of the parts 2 into part of the elastic potential energy when loading the parts 2, and convert the elastic potential energy into the gravitational potential energy of the parts 2 when lifting the parts 2 in the storage space. When the material box 1 is loaded with too many parts 2, the elastic power assisting mechanisms 28 support the bracket mechanism 27, buffer and disperse the gravity of the parts 2. At the same time, it can also reduce the stress of the lifting mechanism 49, play a protective role, and prolong the service life of the lifting mechanism 49.

[0072] In some embodiments, as shown in Figure 10As shown, the elastic assisting mechanism 28 comprises a spring lower seat 29, a spring 30, a spring cover 31 and a limiting assembly 32; the spring lower seat 29 is fixedly arranged relative to the magazine 1, the spring lower seat 29 is internally provided with a compression cavity, the spring 30 is located in the compression cavity, the spring cover 31 is buckled on the spring 30, so that the spring 30 is in a compressed state, the limiting assembly 32 is installed on the spring lower seat 29 and penetrates through the spring 30 and the spring cover 31 and extends above the spring cover 31, the top of the limiting assembly 32 is provided with a stopper limiting the stroke of the spring cover 31, preventing the spring 30 from being separated from the spring lower seat 29; specifically, the limiting assembly 32 and the stopper are composed of a bolt and a nut. When the bracket mechanism 27 is lowered to a certain extent, the spring 30 starts to be compressed, and when the bracket mechanism 27 is raised to a certain height, it will no longer be in contact with the elastic assisting mechanism 28. In addition, the lifting mechanism 49 can be replaced by a hydraulic or pneumatic lifting mechanism 49. A hydraulic or pneumatic pump is arranged near the workbench or the device and is connected to the hydraulic or pneumatic lifting mechanism 49 to drive the bracket mechanism 27 to lift up and down.

[0073] In some embodiments, as shown in Figure 17 The bracket mechanism 27 comprises two first channel steels 33 arranged in parallel, two second channel steels 34 perpendicular to the first channel steels 33 and connected to the first channel steels 33 at the ends, and a plurality of steel plates 56 connected between the two first channel steels 33 or the two second channel steels 34, which serve to support the parts 2.

Figure 22

[0074] In some embodiments, the bottom of the lifting and opening-closing type magazine for loading and unloading the parts 2 further comprises a guide mechanism for guiding the lifting of the bracket mechanism 27, so that the working surface of the bracket mechanism 27 is always in a stable horizontal state, ensuring that the bracket mechanism 27 has only one degree of freedom of upward and downward translation. At the same time, the frictional resistance of the movement of the bracket mechanism 27 is reduced.

[0075] In some embodiments, as shown in Figures 19 to 21 The guide mechanism comprises a plurality of guide columns 37 and a plurality of guide wheels 38, each guide column 37 is vertically installed on the inner wall of the magazine 1, and the plurality of guide wheels 38 are rotatably arranged on the circumference of the bracket mechanism 27 for rolling along the corresponding guide columns 37. Specifically, as shown in Figure 24 The guide column 37 is a three-edged guide column, which is vertically installed on the magazine 1 by welding, riveting, bolting or other fastening methods through a guide column pressing plate 39, and one of the planes of the three-edged guide column is attached to the magazine 1. As shown in Figure 18 ​As shown, two guide wheel boxes are arranged on each of the two second channel steels 34 of the bracket mechanism 27, and the two guide wheel boxes are arranged at an angle outside the three-rib guide column. Each guide wheel box 40 includes two guide wheel boxes arranged in an upper and lower manner. The guide wheel 38 is rotatably installed in a fixed sleeve 41 through a fixed pin. The fixed sleeve 41 is inlaid in the guide wheel box 40, and the fixed sleeve 41 is in contact with the upper and lower surfaces of the guide wheel box 40 and leaves a certain gap around. A jacking bolt 57 is further arranged on the inner wall surface of each guide wheel box 40, and the fixed sleeve 41 is in contact with the jacking bolt 57. The fixed sleeve 41 is moved in the guide wheel box 40 by rotating the jacking bolt 57 to a small extent, so that the guide wheel 38 is in a better contact state with the three-rib guide column. Among them, the guide column 37 has four, and two groups are arranged on the opposite two sides of the material box 1. The guide wheel box 40 has 16, and the upper and lower double-layer arrangement is beneficial to the more stable lifting of the bracket mechanism 27. In addition, the guide wheel box 40 of each guide wheel box group can also be other quantities, as long as the stable lifting of the bracket mechanism 27 can be realized.

[0076] In some embodiments, as shown in Figure 1 , the upper part of the two material boxes 1 away from each other is provided with a side hook 42, and the upper part of the two material boxes 1 close to each other is provided with a middle hook 43. When the hook locking mechanism 50 is in the second state, the side hook 42 on both sides of the hoisting and pulling material box 1 can make the material box 1 open from the middle. The middle hook 43 can be hoisted and pulled to make the material box 1 closed. The number of side hooks 42 and middle hooks 43 can be set according to actual needs.

[0077] In some embodiments, the bottom of the bottom liftable opening and closing type frame for assembling and disassembling parts 2 further comprises a hinged mechanism, as shown in Figure 26 , the hinged mechanism includes a first hinged plate 44 and a second hinged plate 45 respectively installed on the two material boxes 1, and the first hinged plate 44 and the second hinged plate 45 are rotatably connected through a hinged shaft 46. The first hinged plate 44 and the second hinged plate 45 are distributed at both ends of the opening of the material box 1.

[0078] In some embodiments, the first hinged plate 44 or the second hinged plate 45 is further provided with a limiting plate 47 for limiting the opening and closing angle between the first hinged plate 44 and the second hinged plate 45 Figure 26 . One of the material boxes 1 is further provided with a guide plate 48 Figure 25 , and the guide plate 48 and the hinged mechanism jointly act to prevent the two material boxes 1 from being misaligned when closed.

[0079] The working principle and working mode of the bottom liftable opening and closing type frame for assembling and disassembling parts 2 provided by the embodiment of the application are as follows:

[0080] When two bins 1 are in closed state and the inside is full of parts 2, the operator rotates the two-way ratchet wrench 24 to drive a transmission gear 17 to rotate, and the two lifting mechanisms 49 synchronously push the two bracket mechanisms 27 to carry the parts 2 upwards. When the parts are lifted to the upper edge of the bin 1 and are flush with the workbench, the parts 2 can be translated to the workbench manually or by a machine. When the uppermost layer of parts 2 is moved away from the bin 1, the two-way ratchet wrench 24 is continuously rotated to lift the next layer of parts 2. Figure 28

[0081] At this time, the angle between the connecting rod 21 and the screw rod 18 of the lifting mechanism 49 is small, and the connecting rod 21 bears a large resultant force. The elastic assisting mechanism 28 provides an elastic force to the bracket mechanism 27 to offset part of the gravity of the parts 2 and reduce the force borne by the connecting rod 21 of the lifting mechanism 49. The elastic potential energy of the elastic assisting mechanism 28 is gradually released as the lifting mechanism 49 is lifted and is converted into the gravitational potential energy of the parts 2.

[0082] As the parts 2 in the bin 1 gradually decrease, the bracket mechanism 27 gradually rises, and the angle between the connecting rod 21 and the screw rod 18 of the lifting mechanism 49 becomes larger. When the bracket mechanism 27 rises to a certain height and is separated from the elastic assisting mechanism 28, the force borne by the connecting rod 21 is very small.

[0083] When the bin 1 is filled with parts, the bracket mechanism 27 is placed at the highest position. The parts 2 are translated from the workbench to the bracket mechanism 27 manually or by a machine. After a layer of parts 2 is placed, the two-way ratchet wrench 24 is rotated to lower the bracket mechanism 27 to an appropriate height, and the next layer of parts 2 is continuously laid.

[0084] When two bins 1 are in closed state and the hook locking mechanism 50 is in unlocked state, the side hooks 42 on both sides of the bin 1 are pulled by a lifting sling to open the bin 1 and pour out the parts 2 in the bin 1. The middle hook 43 on the bin 1 is pulled by a lifting sling to close the two bins 1. The closed two bins 1 are locked by rotating the handle 12 of the hook locking mechanism 50.

[0085] The above merely describes the preferred embodiments of the present application and is not intended to limit the scope of the present application; if the present application is modified or replaced without departing from the spirit and scope of the present application, all should be covered in the protection scope of the claims of the present application.​
