DETAILED DESCRIPTION

[0028] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application.

[0030] For purposes of the description hereinafter, spatial

[0031] In addition, it should be noted that the use of the terms "first", "second", etc. do not generally limit the scope of the application, unless otherwise indicated. The terms "first", "second" or the like can be used interchangeably with corresponding terms such as "another", unless otherwise indicated by the context.

[0032] With reference to the drawings Figures 1 to 9As shown, the present application provides a stacking device suitable for large mass metal base elements, which comprises two support frames 4 in relative parallel spacing, a stacking space is formed between the two support frames 4, and a lifting carrying device (not marked in the figure) is arranged on the top surface of the two support frames 4. Specifically, each support frame 4 comprises a plurality of vertically arranged stand columns 41, the bottom end of each stand column 41 is fixed to the ground, and a longitudinal rail 42 is connected to the top end of each stand column 41. The lifting carrying device comprises a clamp 1 and a lifting and transverse moving assembly 16 for driving the overall position adjustment of the clamp 1. The lifting and transverse moving assembly 16 specifically comprises a lifting driving assembly 161 for controlling the lifting of the clamp 1 and a transverse driving assembly 162 for translating the clamp 1. The lifting driving assembly 161 and the transverse driving assembly 162 can be realized by using conventional components that can realize lifting and translation functions. The present application does not improve the specific structure thereof. The stacking space is further provided with a stacking and transferring device 3. The stacking and transferring device 3 comprises a bearing platform 31. The running direction of the stacking and transferring device 3 is parallel to the parallel extension direction of the two support frames 4. The stacking device further comprises a stacking limiting device 2. The stacking limiting device 2 comprises two limiting assemblies (not marked in the figure) arranged in relative spacing and corresponding to the positions of the two support frames 4. The clamp 1 is used for clamping the large mass metal base element 100 and placing the large mass metal base element 100 on the bearing platform 31 under the limiting of the limiting assemblies. The stacking and transferring device 3 is used for transferring the large mass metal base element 100 to a target position (such as a vacuum welding chamber) after the stacking of each large mass metal base element 100 is completed.

[0033] In the technical solution, the clamp 1 is used to reliably clamp and carry the large mass metal base element 100 to be stacked, and the stacking limiting device 2 is used to reliably limit the position of the large mass metal base element 100 during stacking. After the stacking is completed, the stacking and transferring device 3 is used to transfer the large mass metal base element 100 to a target position for subsequent process operation, thereby realizing the automatic stacking of the large mass metal base element 100, significantly improving the stacking precision and efficiency, and reducing the safety hazard.

[0034] For reference Figures 2 to 3 As shown, according to the embodiment of the present application, the limiting assembly comprises a limiting frame body 21. The spacing between the two limiting frame bodies 21 can be controlled and adjusted. Each limiting frame body 21 has a limiting groove 22 extending downward in the vertical direction from the top end thereof. The limiting groove 22 is used for rolling limiting connection with the two limiting wheels 15 on the two sides of the load-bearing main body 11 of the clamp 1. Specifically, when stacking, the clamp 1 is hoisted in the space between the two limiting assemblies, and the two limiting wheels 15 on the opposite sides of the load-bearing main body 11 are respectively inserted into the limiting grooves 22 to form rolling limiting connection with the limiting grooves 22.

[0035] In the technical scheme, the two limiting components arranged at a relative interval respectively have a controllable adjustment of the spacing of the limiting frame bodies 21 to achieve accurate limiting of the left and right positions of the clamp 1 between the two limiting components. Meanwhile, the limiting grooves 22 extending upward and downward on the limiting frame bodies 21 are in rolling cooperation with the limiting wheels 15 on the two sides of the load-bearing main body 11 to achieve accurate limiting of the front and back positions of the clamp 1. Thus, the front, back, left and right positions of the metal base units to be stacked can be accurately limited, without excessive manual intervention, and the stacking precision and efficiency can be significantly improved.

[0036] Specifically referring to Figure 2 As shown in some embodiments, the top end slot of the limiting groove 22 is gradually expanded from bottom to top.

[0037] In the technical scheme, the top end slot of the limiting groove 22 is an expanded structure, which can facilitate the limiting wheels 15 on the clamp 1 to be more smoothly positioned into the limiting groove 22.

[0038] In some embodiments, each limiting component further includes a buffer sleeve 23 sleeved outside the limiting frame body 21. The buffer sleeve 23 can be controlled to rise and fall. Specifically, the aforementioned buffer sleeve 23 can be controlled to fall synchronously with the height reduction of the aforementioned clamp 1, and always be below the bottom side height of the clamp 1.

[0039] In the technical scheme, the buffer sleeve 23 is sleeved outside the limiting frame body 21 and can fall synchronously with the clamp 1. When the clamp 1 falls out of control due to failure or the metal base units clamped in the clamp 1 slide off, a buffer support is formed, thereby improving the safety of equipment operation.

[0040] In one specific embodiment, the buffer sleeve 23 includes a buffer base 231 and a buffer cover plate 232 above the buffer base 231. A plurality of buffer springs 233 are arranged at intervals between the buffer cover plate 232 and the buffer base 231. The buffer gap between the bottom surface of the buffer cover plate 232 and the top surface of the buffer base 231 is determined according to the elastic deformation amount of the buffer springs 233. In principle, when the metal base units above or the clamp 1 are supported on the buffer cover plate 232 due to falling off, the buffer gap still has a certain gap, that is, the buffer cover plate 232 and the buffer base 231 are preferably not in contact.

[0041] In the technical scheme, the buffer cover plate 232 is arranged on the top of the buffer spring 233 to uniformly disperse the pressure thereon, thereby ensuring the effective play of the buffer support of the buffer sleeve 23.

[0042] In an embodiment, the buffer sleeve 23 is provided with a lifting drive device 234, which is a rotary motor. The free end of the output shaft of the lifting drive device 234 is provided with a lifting drive gear (not shown and not labeled in the figure). The outer vertical surface of the limiting frame body 21 is formed with a first rack portion (not shown and not labeled in the figure) extending downward. The outer vertical surface of the limiting frame body 21 is provided with a slide rail (not shown and not labeled in the figure) extending upward and downward. The buffer sleeve 23 is in sliding connection with the slide rail. The slide rail and the first rack portion are respectively located on the opposite side walls of the limiting frame body 21. The lifting drive gear is in meshing connection with the first rack portion to drive the buffer sleeve 23 to lift when the lifting drive device 234 operates. It can be understood that the lifting drive device 234 preferably adopts a rotary motor with a brake structure (such as a brake disc and the like). In this way, the position of the buffer sleeve 23 does not need to be locked, and the structure design is simplified.

[0043] In the technical solution, the lifting control of the buffer sleeve 23 is achieved through the meshing mode between the lifting drive device 234 and the limiting frame body 21. The structure design is simple, and the position control is accurate.

[0044] It should be noted that although the rotary motor is used to drive the lifting of the buffer sleeve 23, the height of the buffer sleeve 23 can be accurately followed. However, it should be noted that once the clamp 1 or the metal base element falls off, the teeth between the lifting drive gear and the first rack portion are relatively high in probability of damage. Therefore, as a more optimal embodiment (not shown), the lifting drive device 234 is a lifting telescopic oil cylinder. At this time, the lifting telescopic oil cylinder is fixed to the fixed base 24 described below. The free end of the telescopic rod of the lifting telescopic oil cylinder is connected to the bottom side of the buffer sleeve 23. The lifting telescopic oil cylinder has two telescopic rods, which are respectively supported at the two ends of the length of the buffer sleeve 23. In this way, the extension and retraction of the two lifting telescopic oil cylinders can be controlled to realize the lifting and following of the buffer sleeve 23. It is worth noting that at this time, the lifting telescopic oil cylinder realizes the height adjustment control of the buffer sleeve 23. The damping effect of the hydraulic oil in the oil cylinder forms a buffer support, and the buffer effect of the buffer sleeve 23 is better, and the equipment failure rate is lower.

[0045] In some embodiments, the limiting assembly further comprises a fixed base 24 for fixed connection with the ground to ensure the stability of the entire limiting assembly, the bottom end of the limiting rack body 21 is slidingly and positionally connected with the top surface of the fixed base 24 via an adapter plate 25, and the bottom end of the limiting rack body 21 is slidingly and positionally connected with the top surface of the adapter plate 25, and the aforementioned positionally connected means that the corresponding components such as the aforementioned limiting rack body 21 and the adapter plate 25 can be locked in position after position adjustment, for example, by manually locking the position with components such as positioning blocks.

[0046] In this technical solution, the sliding and positionally connected (i.e. position-locked) structure between the fixed base 24 and the adapter plate 25 and between the adapter plate 25 and the limiting rack body 21 can achieve the stacking limiting precision of the metal-based elements by adjusting the positions of the adapter plate 25 and the limiting rack body 21.

[0047] In some embodiments, the fixed base 24 has a receiving space (not shown or referenced in the drawings) with a top opening (not shown or referenced in the drawings), and a telescopic oil cylinder component 241 is assembled on the fixed base 24, the free end of the telescopic rod of the telescopic oil cylinder component 241 is fixedly connected with the adapter plate 25 to drive the adapter plate 25 to translate.

[0048] In this technical solution, the telescopic oil cylinder component 241 is used to achieve the rapid large displacement adjustment of the adapter plate 25 and the limiting rack body 21 (including the buffer sleeve 23, etc.) thereon, to quickly and efficiently approach the target spacing between the two limiting rack bodies 21, i.e. to achieve the coarse adjustment of the limiting position of the limiting rack body 21.

[0049] In some embodiments, the width of the adapter plate 25 is formed with U-shaped flanges (not referenced in the drawings) bent towards one side of the fixed base 24, and the U-shaped flanges are slidingly connected with the width of the top plate of the fixed base 24.

[0050] In this technical solution, the U-shaped flanges on both sides of the width of the adapter plate 25 are slidingly connected with the top plate of the fixed base 24 in a hoop structure, which can ensure the anti-overturning performance of the upper structure.

[0051] In some embodiments, the U-shaped flanges are provided with end limiting plates 252 at both ends of the length to prevent the displacement adjustment of the adapter plate 25 from being too large and disengaging from the fixed base 24.

[0052] In some embodiments, the adapter plate 25 has two parallel and spaced I-shaped rails 251 integrally formed on the top surface thereof, the bottom end of the limiting frame body 21 is formed with corresponding I-shaped grooves (not shown or labeled in the drawings), the I-shaped rails 251 are slidingly connected in the I-shaped grooves, and the top surface of the I-shaped rails 251 is formed with a second rack portion (not shown or labeled in the drawings), the bottom end of the limiting frame body 21 is provided with a spacing fine adjustment motor 26, the shaft of the spacing fine adjustment motor 26 has a fine adjustment gear (not shown or labeled in the drawings), and the fine adjustment gear is engaged with the second rack portion.

[0053] In the technical solution, the relative positions of the limiting frame body 21 and the adapter plate 25 are adjusted by the spacing fine adjustment motor 26, the adjustment accuracy is higher, the position accuracy of each limiting frame body 21 is ensured, and the stacking accuracy of the metal-based elements is improved. In a specific embodiment, the single-side position difference (also referred to as the single-side gap of the group blank) between the upper and lower metal-based elements after stacking is within ±1mm. It should be emphasized that the position of the adapter plate 25 is efficiently and coarsely adjusted by the telescopic oil cylinder component 241, so that the limiting frame body 21 can be quickly moved to the target spacing (target position), and then the position (spacing) of the limiting frame body 21 is further finely adjusted by the spacing fine adjustment motor 26, which obviously improves the efficiency of spacing adjustment while ensuring the accuracy of spacing adjustment.

[0054] For reference Figures 4 to 6 As shown in the drawings, according to the embodiment of the present application, the clamp 1 comprises a bearing main body 11 and a displacement driving assembly (not shown or labeled in the drawings), the bearing main body 11 is provided with two clamping plates 12 on the bottom surface thereof, which can be driven by the displacement driving assembly to approach or move away from each other along a first horizontal direction, each clamping plate 12 is formed with a load preventing boss 121 on the clamping surface (i.e. the surface in contact with the side wall surface of the clamping object, i.e. the large mass metal-based element 100) opposite to each other, the load preventing boss 121 extends along a second horizontal direction with reference to the orientation of the clamp in the clamping state, the load preventing boss 121 can extend into the groove on the outer wall surface of the large mass metal-based element 100 to bear the weight of the large mass metal-based element 100 in the vertical direction when the clamp is in the clamping state, and the second horizontal direction is perpendicular to the first horizontal direction.

[0055] The technical scheme is characterized in that the load-preventing convex blocks 121 are arranged on the clamping surfaces of the two clamping plates 12, so as to be inserted into the grooves on the outer wall surface of the large-mass metal base 100 when the large-mass metal base 100 is clamped and transferred. In the specific use process, the mass of the large-mass metal base 100 is borne by the top surface of the load-preventing convex block 121, and the displacement driving assembly does not need to provide a clamping force matching the weight of the large-mass metal base 100, but only needs to provide displacement driving of the clamping plate 12, which can greatly reduce the driving power requirement of the displacement driving assembly, and greatly improve the stability of the relative position of the clamping plate 12 and the large-mass metal base 100, thereby ensuring the safety of the clamping and transfer of the large-mass metal base 100.

[0056] In order to improve the reliability of clamping and transfer, the aforementioned load-preventing convex blocks 121 can be arranged in parallel in multiple rows. Figure 5 In the embodiment shown in the figure, three rows are arranged.

[0057] In some embodiments, the protruding height of the load-preventing convex block 121 is not less than 0.4 mm and not greater than 0.6 mm, and in a specific embodiment, 0.5 mm is adopted; and the vertical width of the load-preventing convex block 121 is 80 mm to 100 mm.

[0058] In the technical scheme, the protruding height of the load-preventing convex block 121 is designed to be 0.4 mm to 0.6 mm and the vertical width is 80 mm to 100 mm, which can not only meet the reliable bearing of the load-preventing convex block 121 and prevent the large-mass metal base 100 from falling off, but also can minimize the groove opening size of the large-mass metal base 100, thereby improving the metal utilization rate of the large-mass metal base 100.

[0059] It should be noted that, in order to ensure the accuracy of the left and right positions of the large-mass metal base 100, the groove depth of the groove on the large-mass metal base 100 should be greater than the protruding height of the load-preventing convex block 121, so as to ensure that the clamping surface of the clamping plate 12 can be attached to the side wall surface of the large-mass metal base 100.

[0060] In a preferred embodiment, a wear-resistant layer is formed on the top surface of the aforementioned load-preventing convex block 121 (i.e., the surface that is matched with the upper and lower groove walls of the groove of the large-mass metal base 100), so as to improve the service life of the clamping plate 12.

[0061] In one embodiment, the groove on the large mass metal base 100 can be machined in advance before transfer, while in another embodiment not shown, a corresponding slotting device, such as a milling device, can be integrated on the aforementioned clamping plate 12, which is controlled to operate to machine the groove on the wall surface of the large mass metal base 100 first when the clamping plate 12 clamps the large mass metal base 100, so as to simplify the operation process, realize on-site machining of the large mass metal base 100, and improve the stacking efficiency. It should be noted that the aforementioned milling device can use a milling device with appropriate specifications and sizes available on the market. Since the size of the groove is small, the overall size of the milling device can be relatively small. The present application does not intend to improve the structure of the milling device, and thus will not be described here.

[0062] In some embodiments, a first sliding groove 112 extending in the first horizontal direction is formed on the bottom surface of the load-bearing body 11, and the top ends of the two clamping plates 12 are slidingly connected in the first sliding groove 112, and the top ends of each clamping plate 12 are limited in the first sliding groove 112 in the vertical direction, as shown in Figure 2 Alternatively Figure 3 As shown, a T-shaped end is formed at the top end of the clamping plate 12, and the cross section of the corresponding first sliding groove 112 is also T-shaped. The T-shaped end is matched and assembled in the T-shaped first sliding groove 112, so as to realize the sliding of the clamping plate 12 in the direction of extending along the groove body of the first sliding groove 112, while limiting the clamping plate 12 in the vertical direction, that is, realizing the transfer of the mass of the large mass metal base 100 from the load-preventing boss 121 on the clamping plate 12 to the load-bearing body 11.

[0063] It can be understood that the aforementioned load-bearing body 11 will be assembled on a truss trolley, a lifting mechanism, a mechanical arm, etc. in specific applications, and the aforementioned mechanisms are used to drive the clamp suitable for the large mass metal base to move in position in the target space.

[0064] Referring to Figure 4As shown, in some embodiments, the displacement driving assembly is assembled on the top surface of the load-bearing body 11, the displacement driving assembly comprises a rotary motor 131 and two lead screws 132, the rotary motor 131 is fixedly assembled on the top surface of the load-bearing body 11, in a specific embodiment, a mounting block 113 is formed on the top surface of the load-bearing body 11, the rotary motor 131 is fixed on the mounting block 113, a driving bevel gear (not shown, not referenced in the figure) is arranged on the output shaft of the rotary motor 131, the first end of each of the two lead screws 132 is provided with a driven bevel gear, each of the driven bevel gears is in tooth meshing connection with the driving bevel gear, a hollow space for accommodating the driving bevel gear and the driven bevel gear is formed in the mounting block 113, each of the lead screws 132 is pivotally connected to the top surface of the load-bearing body 11 through a corresponding support seat (not shown in the figure), and a nut 133 is threadedly sleeved on each of the lead screws 132, the two clamping plates 12 can be driven by one of the nuts 133 to move linearly along the first sliding groove 112.

[0065] In the technical solution, the driving bevel gear of the centrally arranged rotary motor 131 synchronously rotates the two lead screws 132 on both sides of the rotary motor 131, and then the nuts 133 threadedly sleeved on the lead screws 132 drive the two clamping plates 12 to move linearly towards or away from each other, the structure is simple and compact, the output clamping force is large, and the relative position of the two clamping plates 12 during the use of the clamp can be reliably stabilized by using the thread self-locking of the nut 133 and the lead screw 132, thereby improving the use safety of the clamp.

[0066] It should be noted that the selection and rotation direction of the thread teeth of the lead screw 132 can be reasonably selected according to the working conditions, and the present application will not be described in detail.

[0067] In a specific embodiment as shown in Figure 4 In a specific embodiment as shown in

[0068] In the technical solution, the two groups of displacement driving assemblies are arranged to drive the linear reciprocating translation of the connecting plate, and then drive each of the clamping plates 12 on both sides to move close to or away from each other, so that the movement of the clamping plate 12 can be reliably smooth, and the top end of the clamping plate 12 is detachably connected to the connecting plate, so that the replacement of the clamping plate 12 is convenient.

[0069] Specifically, referring to Figure 5 andFigure 6 As shown, the clamping surface structure of the clamping plate 12 varies according to the shape of the clamping object, i.e. the aforementioned large mass metal base 100. Specifically, when the large mass metal base 100 is a cubic column, the clamping surface of the clamping plate 12 is Figure 2 a flat surface as shown, while when the large mass metal base 100 is a cylindrical column, the clamping surface of the clamping plate 12 is Figure 3 a concave surface as shown, which can be a concave arc surface matching the cylindrical column surface, or Figure 3 a concave trapezoidal surface as shown. Since the top end of the clamping plate 12 is detachably connected to the connecting plate, the clamping plate 12 matching the clamping surface can be replaced according to the specific shape of the large mass metal base 100.

[0070] In some embodiments, the connecting plate is slidingly connected in the first sliding groove 112, and the connecting plate and the aforementioned nut 133 are detachably fixed as a whole. The sliding connection of the connecting plate in the first sliding groove 112 can further improve the stability of the translation of the clamping plate 12.

[0071] Further referring to Figure 4 As shown, in some embodiments, the bottom surface of the load-bearing body 11 is further provided with two limit plates 14 arranged at a distance. The distance between the two limit plates 14 can be adjusted along the second horizontal direction to limit the displacement of the large mass metal base 100 in the second horizontal direction.

[0072] In this technical solution, by arranging two limit plates 14 at a distance in the second horizontal direction, reliable limiting of the large mass metal base 100 can be achieved, effectively preventing the slip displacement in the second horizontal direction during the transfer (stacking) of the large mass metal base 100, and further ensuring the positional accuracy of the metal stack.

[0073] In some embodiments, the bottom surface of the load-bearing body 11 is formed with a second sliding groove 111 extending along the second horizontal direction, and the top end of the limiting plate 14 is slidingly limited in the second sliding groove 111 to facilitate the adjustment of the position of the limiting plate 14. The aforementioned limiting plate 14 can be fixedly connected between the load-bearing body 11 at a target position in a manual mechanical manner, for example, a limiting block (not shown in the figure) is arranged on the side of each limiting plate 14 away from the massive metal element 100 in the second sliding groove 111, a corresponding push bolt (not shown in the figure) is threadedly connected to the limiting block, the cross section of the limiting block and the cross section of the second sliding groove 111 are both T-shaped, that is, the limiting block is limited in the second sliding groove 111 in the vertical direction but can be pushed and slid along the extending direction of the groove body of the second sliding groove 111, when the limiting block is pushed to the target position, the push bolt is rotated to make its free end push on the groove bottom wall of the second sliding groove 111, thereby forming a locking of the position of the limiting block, and further realizing a locking of the position of the limiting plate 14.

[0074] In some embodiments, the load-bearing body 11 is respectively provided with a limiting wheel 15 on each of the two side walls in the first horizontal direction, and the limiting wheel 15 is used to rollingly cooperate with a limiting groove (not shown in the figure) on a limiting support (not shown in the figure). It can be understood that the aforementioned limiting support has two left and right spaced limiting grooves extending upward and downward along the vertical direction. In the specific stacking of the massive metal element 100, after the two clamping plates 12 and the two limiting plates 14 of the clamp are respectively driven to the target positions to reliably clamp the massive metal element 100, the clamp is moved to the area between the two limiting supports under the driving of the aforementioned gantry crane, hoist, mechanical arm or the like, and the precise center stacking of each massive metal element 100 transferred in front and back is realized by the cooperation of the two limiting wheels 15 on the two sides of the load-bearing body 11 with the limiting grooves on the limiting support, thereby improving the position accuracy of each massive metal element 100 stacked and stacked upward and downward.

[0075] In an embodiment not shown in the figure, a high-pressure air jet device (not shown in the figure) is integrated in the clamping plate 12 to blow off impurities on the surface of the blank. Specifically, the air jet port of the aforementioned high-pressure air jet device can be driven to extend into the bottom side of the massive metal element 100 in the hoisted state clamped by the clamp, so as to clean the bottom surface of the massive metal element 100 (to be stacked) in the hoisted state and the top surface of the massive metal element 100 already stacked to the target position in the previous process by using high-pressure airflow, to ensure the cleanliness of the matching position between each massive metal element 100 stacked, and to improve the quality of the subsequent solid additive manufacturing blank.

[0076] For reference Figures 7 to 9As shown, according to the embodiment of the present application, the stack transfer device 3 further comprises a traveling mechanism (not labeled in the figure), which can drive the carrying platform 31 to travel autonomously, and the carrying platform 31 is provided with a first sliding groove 311 and a second sliding groove 312 on the carrying surface thereof, the length extension directions of the first sliding groove 311 and the second sliding groove 312 form a cross, that is, the first sliding groove 311 and the second sliding groove 312 are perpendicular to each other on the carrying surface of the carrying platform 31, the first sliding groove 311 is provided with two first positioning sliding blocks 313 which can be driven to approach or move away, the second sliding groove 312 is provided with two second positioning sliding blocks 314 which can be driven to approach or move away, and the two first positioning sliding blocks 313 and the second positioning sliding blocks 314 can form position adjustment and positioning for the metal base element placed on the carrying surface, it can be understood that the first positioning sliding blocks 313 and the second positioning sliding blocks 314 are preferably respectively and one-to-one connected with the sliding guide connection between the groove walls of the first sliding groove 311 and the second sliding groove 312, so as to ensure the reliable stability of the reciprocating linear motion of the first positioning sliding blocks 313 and the second positioning sliding blocks 314, the first positioning sliding blocks 313 and the second positioning sliding blocks 314 are specifically connected with the corresponding sliding block driving components 317, so as to realize reliable driving of the first positioning sliding blocks 313 and the second positioning sliding blocks 314 through the operation of the sliding block driving components 317, the sliding block driving components 317 may, for example, adopt a linear motor with sufficient output, of course, in a preferred embodiment, a hydraulic cylinder can be adopted, which can have greater output and be suitable for a wider working condition, and more preferably, each of the first positioning sliding blocks 313 and the second positioning sliding blocks 314 is respectively provided with a sliding block driving component 317, so as to realize flexible adjustment of the position of each positioning sliding block, and further make the adjustment and positioning of the position of the metal base element placed on the carrying surface more flexible and accurate.

[0077] In the technical solution, the carrying platform 31 can autonomously travel under the driving of the traveling mechanism, so as to efficiently adjust the relative position between the carrying surface of the carrying platform 31 and the metal base element to be stacked, that is, to realize coarse adjustment, and improve the alignment efficiency of the metal base element stacking, at the same time, the first positioning sliding blocks 313 and the second positioning sliding blocks 314 which move perpendicular to each other are arranged on the carrying surface of the carrying platform 31, so as to realize accurate adjustment of the centering and positioning of the four positions of the metal base element on the carrying surface, which can further improve the position accuracy of the metal base element, and further improve the position accuracy of the metal base element after being stacked up and down, in addition, through the action of the first positioning sliding blocks 313 and the second positioning sliding blocks 314 which form clamping positioning in pairs, the stability of the metal base element during the stacking process can be ensured, and the position deviation caused by the placement impact of the metal base element during the stacking process can be prevented.

[0078] In some embodiments, the bearing platform 31 has a first side (not shown in the figure) and a second side (not shown in the figure) which are positionally matched with the stacking limiting device (not shown in the figure) arranged at the periphery of the bearing platform 31, which can guide and limit the left and right positions and the front and back positions of the lifting clamps of the metal base units to ensure the position accuracy of the metal base units during stacking. The first sliding groove 311 is perpendicular to the first side and the second side, and the bearing surface is further provided with an assembly groove 315, and a support component 316 is assembled in the assembly groove 315, which can be supported on the bottom side end surface of the metal base unit and in sliding contact with the bottom side end surface of the metal base unit. By supporting the sliding contact of the bottom side end surface of the metal base unit by the support component 316, the friction between the metal base unit and the bearing surface can be reduced, and the smooth adjustment of the first positioning sliding block 313 and the second positioning sliding block 314 to the position of the metal base unit can be ensured.

[0079] In some embodiments, the aforementioned support component 316 can be a roller group (composed of multiple rollers) pivotally connected to the bearing surface. Although this structure of the support component 316 can achieve sliding contact with the bottom side end surface of the metal base unit, the bearing capacity of the roller group is limited due to the corresponding pivot connection of the shaft, which leads to the shaft being easily damaged under the action of a large mass of metal base units, resulting in a lower service life. As another preferred embodiment, the support component 316 is a support rail, which is fixedly assembled in the aforementioned assembly groove 315, and the rail top surface of the support rail is provided with multiple balls arranged along the length thereof (not shown in the figure). According to the actual bearing requirements, the width of the rail top surface of the support rail can be designed to be larger to form a larger support plane. Correspondingly, multiple rows of balls are arranged along the width of the rail top surface. The support rail can bear the weight of a large mass of metal base units, has large bearing capacity, reliable and stable structure, and long service life. It can be understood that each ball can slightly protrude from the rail top surface, and the rail top surface can be at the same height as the aforementioned bearing surface. In a preferred embodiment, the support component 316 is symmetrically arranged on both sides of the first sliding groove 311.

[0080] In some embodiments, the stacking and transferring device also includes a base platform 32, and the base platform 32 has a rotating mechanism (not marked in the figure), and the rotating mechanism includes a turntable 321 and a rotating drive component 322 for driving the turntable 321 to rotate. The supporting platform 31 is assembled on the top surface of the turntable 321.

The driving gear is engaged with the ring gear 3211 to form a rotational drive of the turntable 321 by the rotating drive component 322. It should be noted that the aforementioned rotating drive component 322 adopts corresponding rotating components with sufficient driving force, such as hydraulic motors, rotary motors and corresponding transmission and deceleration mechanisms. As conventional design components in the mechanical field, the present invention does not elaborate on them.

[0081] In this technical solution, by placing the carrying platform 31 on a rotating disk 321 that can be driven to rotate, the circumferential position of each stacked metal element can be adjusted by controlling the rotation of the rotating disk 321. In this way, when the adjacent metal elements are welded together, the corresponding welding device (not shown in the figure) does not need to move around the circumference of the metal element to achieve its position at a fixed position (for example, Figure 1 The rear end of the supporting platform 31 in the shown orientation is used to weld the metal element at various circumferential positions, thereby facilitating the welding process of the metal element.

[0082] See Figure 9 As shown, in some embodiments, an assembly cavity (not marked in the figure) with an upward opening is formed on the top surface of the base platform 32, the turntable 321 and the rotating drive component 322 are assembled in the assembly cavity, and the supporting platform 31 can completely cover the opening of the assembly cavity.

[0083] In this technical solution, an assembly cavity with an upward opening is formed on the top surface of the base platform 32, so that the turntable 321, the rotating drive component 322 and other components can be assembled in the assembly cavity, and the assembly cavity is sealed through the supporting platform 31. In this way, the structure of the stacking and transferring device of the present invention can be made more compact, and the safety of the device can be improved.

[0084] In some embodiments, the walking mechanism comprises walking wheels 331 at the four corners of the bearing platform 31 and walking driving components 332 for driving the synchronous rotation of each of the walking wheels 331, at this time, the aforementioned walking driving components 332 and the slider driving components 317 are also accommodated in the aforementioned assembly cavity, further improving the structural compactness and use safety of the device. It can be understood that the aforementioned walking driving components 332 can adopt corresponding hydraulic motors or electric motors and at the same time configure corresponding transmission devices and reduction devices, which are relatively common designs in the mechanical field, and the present application will not be described in detail.

[0085] In some embodiments, the stacking and transferring device further comprises a power-assisted traction device 34, which is detachably connected with the base platform 32, that is, the power-assisted traction device 34 is an optional component, which can be used in the case of large stacking quality to form a resultant force with the aforementioned walking driving components 332, thereby improving the traction motive of the stacked metal base element (group blank) and ensuring the efficient performance of the transferring operation.

[0086] In order to facilitate the connection process of the power-assisted traction device 34 and the base platform 32, in some embodiments, the power-assisted traction device 34 and the base platform 32 are connected by electromagnetic attraction, specifically, the base platform 32 has a first traction rod 323, the free end of the first traction rod 323 is fixedly connected with a first electromagnetic suction disc 3231, the power-assisted traction device 34 has a second traction rod 341, the free end of the second traction rod 341 is fixedly connected with a second electromagnetic suction disc 3411, the first electromagnetic suction disc 3231 and the second electromagnetic suction disc 3411 have opposite magnetism when energized, and the electromagnetic suction disc can adjust the magnetic attraction force by passing current, which is convenient and fast.

[0087] In some embodiments, the first positioning slider 313 and the second positioning slider 314 both have a positioning portion (that is, the portion in contact with the metal base element) protruding from the bearing surface and a connection driving portion (that is, the portion connected with the slider driving components 317) in the first sliding groove 311 or the second sliding groove 312, the top surface of the connection driving portion is lower than the height of the bearing surface by h, h>2mm, to prevent the connection driving portion from contacting and rubbing the bottom side end surface of the metal base element.

[0088] In some embodiments, the stacking device suitable for large mass metal base elements further comprises a surface difference measuring device 5 for measuring the surface difference between the blanks after stacking to detect the precision of the stacking in real time, so as to timely adjust the positional precision of the stacking related devices. In one specific embodiment, the aforementioned surface difference measuring device 5 is provided with two, each of the surface difference measuring devices 5 is arranged on the opposite sides of the large mass metal base element 100.

[0089] In some embodiments, a ground rail 6 is further arranged in the stacking space, the extending direction of the ground rail 6 extending along the parallel direction of the support frame 4, and the travel of the stacking transfer device 3 is guided by the ground rail 6.
