A first feature being "below", "below" and "below" a second feature includes that the first feature is directly below and obliquely below the second feature, or simply indicates that the first feature is lower in level than the second feature.

[0057] In the description of this embodiment, the terms "upper", "lower", "right", etc., are based on the directions or positions shown in the drawings, and are only for the convenience of description and simplified operation, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation of the present invention. In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.

[0058] This embodiment provides a sliding structure, a clamping mechanism and a lifting and flipping device, wherein the lifting and flipping device includes a clamping mechanism, and the clamping mechanism includes a sliding structure, which improves the convenience of the workpiece assembly process. The lifting and flipping device can be used to clamp, lift and flip the workpiece so that the posture of the workpiece meets the processing requirements. In this embodiment, the workpiece can be the base of the environmental test box. In other embodiments, the workpiece can also be other parts with larger mass, which is not specifically limited here.

[0059] like Figure 1 As shown in the figure, the X direction, Y direction and Z direction in the figure are three directions perpendicular to each other in space, the X direction, Y direction and Z direction represent the first direction, the second direction and the third direction respectively, the X direction and the Y direction represent the horizontal direction, and the Z direction represents the vertical direction. The lifting and flipping device includes two bracket mechanisms 10, two lifting drive mechanisms 20, two flipping drive mechanisms 30, two support mechanisms 50 and a clamping mechanism 40. Among them, the two bracket mechanisms 10 are arranged along the first direction (i.e. Figure 1 The two support mechanisms 10 are arranged at intervals (in the X direction in the figure), each lifting drive mechanism 20 is correspondingly installed on a support mechanism 10, and each support mechanism 50 is correspondingly connected to the output end of a lifting drive mechanism 20 and is guided and matched with the corresponding support mechanism 10. The flipping drive mechanism 30 is installed on the support mechanism 50, so that the lifting drive mechanism 20 can drive the corresponding flipping drive mechanism 30 to move up and down in the vertical direction. The clamping mechanism 40 is located between the two support mechanisms 10 and is used to clamp the base. The output ends of the two flipping drive mechanisms 30 are connected to the clamping mechanism 40, and can drive the clamping mechanism 40 to rotate around the flipping axis parallel to the X direction.

[0060] When the lifting and flipping device of this embodiment is used to assemble the base, the clamping mechanism 40 can be first driven downward to a position close to the ground by two lifting drive mechanisms 20, so that the clamping mechanism 40 can directly grab the base placed on the ground; then the two lifting drive mechanisms 20 jointly drive the clamping mechanism 40 and the base to a height sufficient for the base to flip; then the two flipping drive mechanisms 30 jointly drive the clamping mechanism 40 and the base to flip around a flip axis parallel to the first direction, so as to adjust the base to a desired tilt angle. The lifting and flipping device of this embodiment can automatically grasp, lift and flip the base, without the need for manual handling of the base, with high operating efficiency and low labor costs. In addition, since the mass of the base is large, the clamping mechanism 40 and the base are lifted and lowered by two lifting drive mechanisms 20, and the clamping mechanism 40 and the base are flipped by two flipping drive mechanisms 30, so that the force of the clamping mechanism 40 is balanced, and the lifting and flipping of the base are more stable.

[0061] like Figure 1 As shown, the support mechanism 10 includes a bottom plate 13, a top plate 14 and two H-shaped steels 11, wherein the bottom plate 13 is used to be placed on the ground, and a mounting hole is provided on the bottom plate 13, so that the bottom plate 13 can be fixed to the ground by bolts to improve the stability of the support of the support mechanism 10. The two H-shaped steels 11 are both installed on the bottom plate 13 and extend in the vertical direction (i.e. Figure 1 The top plate 14 is installed on the top of the H-shaped steel 11. The cooperation of the bottom plate 13, the top plate 14 and the two H-shaped steels 11 makes the entire bracket mechanism 10 have a high structural strength. For the H-shaped steel 11, its cross section is H-shaped and includes a web 111 and two flange plates 112. In this embodiment, the webs 111 of the two H-shaped steels 11 are arranged along the second direction (i.e. Figure 1 The two flange plates 112 of each H-shaped steel 11 are arranged in the first direction (i.e., the Y direction in the figure), and each web plate 111 is perpendicular to the second direction. Figure 1 The flange plates 112 are arranged opposite to each other in the X direction, and the flange plates 112 are perpendicular to the first direction, so that an accommodating space 12 is formed between the two H-shaped steels 11 at this time.

[0062] like Figure 1As shown, the lifting drive mechanism 20 is installed on the top plate 14, and the output end extends downward into the accommodating space 12. The support mechanism 50 includes a support inner frame 51, which is arranged in the accommodating space 12 formed by the two H-shaped steels 11. The output end of the lifting drive mechanism 20 is connected to the support inner frame 51, and the flip drive mechanism 30 is installed on the support inner frame 51. The support mechanism 10 is composed of H-shaped steel 11, which not only has good structural strength, but also naturally forms an accommodating space 12 that can accommodate the output end of the lifting drive mechanism 20 and the flip drive mechanism 30, which not only protects the lifting drive mechanism 20 and the flip drive mechanism 30, but also prevents accidental injury to the operator. In this embodiment, the support mechanism 50 also includes a support outer frame 52 and a guide assembly (not shown), the support outer frame 52 is arranged around the outer periphery of the two H-shaped steels 11 and connected to the support inner frame 51, and the guide assembly is connected to the support outer frame 52 and cooperates with the H-shaped steel 11 to guide the lifting and lowering movement of the flip drive mechanism 30. The guide assembly can be a roller assembly, or can be a combination of a linear guide rail and a slider.

[0063] Optionally, the lifting drive mechanism 20 can be a component capable of outputting linear motion, such as an oil cylinder or an air cylinder, which is not specifically limited here. The flipping drive mechanism 30 can include a rotary motor, which can be directly connected to the clamping mechanism 40 or connected to the clamping mechanism 40 through a transmission structure, as long as it can drive the clamping mechanism 40 to rotate around an axis extending in the first direction.

[0064] like Figure 2 As shown, the clamping mechanism 40 includes a sliding structure, specifically, the sliding structure includes a carrier frame 41 and two clamping end frames 42. The clamping end frames 42 can move along a first direction (i.e. Figure 2 The clamping mechanism 40 also includes two first drive assemblies 45, a plurality of second drive assemblies 46 and a clamping member 47. The carrier 41 is a frame structure roughly parallel to the first direction, and the output ends of the two flip drive mechanisms 30 are connected to the two ends of the carrier 41 along the first direction. The two first drive assemblies 45 are installed on the carrier 41, and the output ends of the two first drive assemblies 45 are connected to the two clamping end frames 42 correspondingly, and can drive the corresponding clamping end frames 42 to approach or move away from each other along the first direction. At least one second drive assembly 46 is installed on each clamping end frame 42, and a clamping member 47 is connected to the output end of each second drive assembly 46. The two first drive assemblies 45 can drive the clamping member 47 to clamp or approach the base in the first direction, and the second drive assembly 46 can drive the corresponding clamping member 47 to move along the first direction and / or the third direction to fix the base on the carrier 41.

[0065] In this embodiment, the first drive assembly 45 may be a cylinder or an oil cylinder, and its output end extends along the first direction. The output directions of the two first drive assemblies 45 are opposite, so as to drive the clamping members 47 on the two clamping end frames 42 to limit and clamp the base along the first direction. The second drive assembly 46 may be a cylinder or an oil cylinder. In some embodiments, the second drive assembly 46 can drive the corresponding clamping member 47 to move along the third direction, so that after the two first drive assemblies 45 drive the clamping member 47 to limit the base along the first direction, the base is further clamped on the carrier 41 along the third direction. In some embodiments, the second drive assembly 46 can drive the corresponding clamping member 47 to move along the first direction, so that after the two first drive assemblies 45 drive the clamping member 47 to limit the base along the first direction, the clamping member 47 is further driven along the first direction to ensure the clamping reliability of the clamping member 47 on the base. In some embodiments, the first drive component 45 can drive the corresponding clamping member 47 to move along the first direction and the third direction, so that after the two first drive components 45 drive the clamping member 47 to limit the base along the first direction, the base is further clamped in the first direction, and the base is pressed onto the support frame 41 in the third direction. Of course, in this embodiment, the second drive component 46 can include two drive sources.

[0066] like Figure 2 and Figure 3 As shown, the carrier 41 is welded by a plurality of channel steels, wherein some of the channel steels are surrounded to form two closed structures 412, and the two closed structures 412 are arranged along the first direction. The notch of the channel steel at each closed structure 412 is arranged toward the inner side of the closed structure 412, thereby forming a slideway 411. Each clamping end frame 42 is correspondingly arranged in a closed structure 412, and pulleys 43 are installed at both ends of the clamping end frame 42 along the second direction. The pulleys 43 at both ends of the clamping end frame 42 roll in the slideway 411 in the corresponding position, thereby reducing wear and providing movement guidance when the first drive assembly 45 drives the clamping end frame 42 to move relative to the carrier 41 along the first direction. In this embodiment, the clamping end frame 42 includes two first support members 421 and two second support members 422, the two first support members 421 both extend along the first direction and are arranged oppositely in the second direction, and the two second support members 422 both extend along the second direction and are arranged oppositely in the first direction, thereby forming a quadrilateral structure. The second drive assembly 46 is installed on the quadrilateral structure.

[0067] In the prior art, in order to install the pulley in a closed slideway, the pulley is usually installed in the slideway before the support frame is welded and sealed, and then the frame is welded into a closed state. However, during the welding process, the channel steel may be stuck due to factors such as stress contraction, which requires a lot of time to adjust and correct.

[0068] In this regard, Figure 2 , Figure 4 and Figure 5 As shown, the sliding structure further includes a plurality of fastening components 44, and the ends of the two first supporting members 421 along the first direction are provided with U-shaped grooves 4211, and the depth direction of the U-shaped grooves 4211 is parallel to the first direction. The pulley 43 includes a pulley body 431 and a pulley shaft 432 extending along the first direction, the pulley body 431 is arranged in the slideway 411 at the corresponding position and rollingly cooperates with the slideway 411, the pulley shaft 432 is inserted into the corresponding U-shaped groove 4211 along the first direction, the fastening component 44 is connected to the pulley shaft 432, and the fastening component 44 and the pulley body 431 are respectively clamped on both sides of the first supporting member 421 along the second direction.

[0069] When assembling the sliding structure of the present embodiment, the support frame 41 can be welded to form a closed structure 412 first. After welding, the pulley 43 can be directly slid in the slideway 411 to confirm whether it will get stuck. If it gets stuck, the support frame 41 is polished and corrected. If it does not get stuck, the subsequent assembly is performed. Then, the clamping end frame 42 is placed in the closed structure 412. Then, the pulley bodies 431 of the two pulleys 43 are inserted into the slideway 411 located at the two ends of the clamping end frame 42 along the second direction, so that the pulleys 43 move in the slideway 411 until the two ends are in contact with each other. The pulley shafts 432 of the pulleys 43 are respectively inserted into the U-shaped grooves 4211 of the first support member 421; then the two sets of fastening components 44 are respectively connected to the two pulley shafts 432; at this time, for each pulley 43 and the clamping end frame 42, the fastening components 44 and the pulley body 431 are respectively clamped on both sides of the first support member 421 along the second direction, and for the entire sliding structure, the pulleys 43 at both ends of the clamping end frame 42 along the second direction are respectively inserted into the slideway 411, thereby realizing the connection between the clamping end frame 42 and the carrier frame 41. The sliding structure of this embodiment can install the pulley 43 after the carrier frame 41 is welded to form the closed structure 412, so as to ensure that the pulley 43 will not be stuck before installation, thereby improving the convenience of installation of the pulley 43 and reducing the workload and time of correction. The clamping mechanism 40 and the lifting and flipping device of this embodiment adopt the above-mentioned sliding structure, which is convenient to assemble, efficient, and the clamping end frame 42 runs smoothly.

[0070] In this embodiment, each first support member 421 is provided with a U-shaped groove 4211 at both ends along the first direction, and a pulley 43 is correspondingly installed at each U-shaped groove 4211 through a fastening assembly 44. In other words, each clamping end frame 42 cooperates with the carrier 41 through four pulleys 43, has a good guiding effect, and can ensure the stability of the movement process of the carrier 41.

The sliding structure in this embodiment forms a cover protection for the pulley 43 and the fastening assembly 44 through the structure of the first support member 421 itself. The second support member 422 is also a channel steel, and the notches of the two second support members 422 of the clamping end frame 42 are arranged in a direction away from each other, and the groove of the second support member 422 is connected to the groove of the first support member 421.

In this embodiment, the end of the second support member 422 is inserted into the groove of the corresponding first support member 421. This arrangement not only allows the first support member 421 and the second support member 422 to support each other, but also increases the welding position between the two, thereby improving the structural firmness of the clamping end frame 42.

[0072] Preferably, if Figure 5 As shown, a locking hole 4221 is provided at the end of the second support member 422, and the sliding structure further includes a locking member (not shown), which is connected to the corresponding fastening assembly 44 after passing through the locking hole 4221, that is, the fastening assembly 44 is fixed by the locking member to prevent the fastening assembly 44 from falling along the first direction, thereby improving the connection reliability of the sliding structure. In this embodiment, the locking member is a bolt, and a threaded hole is provided on the fastening assembly 44.

Optionally, for each fastening assembly 44, one or more fasteners can be configured, and the number of locking holes 4221 can match the number of fasteners. Of course, in some embodiments, the locking hole 4221 can also be selected to be arranged on the first support member 421. In other embodiments, the locking hole 4221 can be set on both the first support member 421 and the second support member 422, and the fastening assembly 44 can be locked by the fastener.

In addition, this structural setting of the fastening assembly 44 can reliably fix the corresponding pulley 43 on the clamping end frame 42 without setting a locking member. In this embodiment, a penetration hole 4421 is provided on the fixing block 442, and the penetration hole 4421 extends along the second direction and is provided for the pulley shaft 432 to pass through.
