Description

Technical Field

[0001] The utility model relates to the technical field of supporting devices, in particular to a supporting device and an assembly production line of an evaporator formed therefrom. Background Art

[0002] The evaporator of the circular cabinet is usually designed in a U-shape or a V-shape to adapt to the shape of the circular body. The U-shape or V-shape structural profile cannot be placed stably using a flat support device. During the evaporator assembly process, if the evaporator cannot be placed stably, it will affect the assembly efficiency of the evaporator and the cabinet.

[0003] For U-shaped or V-shaped evaporators, the existing support devices are mainly designed to imitate the product shape. Different series of evaporators have different sizes, angles, and heights. According to conventional designs, dozens of support devices need to be designed to meet production needs. This leads to complex production management of evaporator support equipment, and the production line needs to switch support devices as the product switches, resulting in a waste of switching time, which does not meet the requirements of lean production. Utility Model Content

[0004] In order to overcome the problems existing in the related art, one of the purposes of the utility model is to provide a support device, which drives the support plate to rotate through a rotating shaft and adjusts the angle between the two support plates to adapt to evaporator supports with different bending angles.

[0005] A supporting device comprises two supporting plates arranged parallel to a first direction, wherein one end surface of the supporting plate is used to support a workpiece, and the other end surface of the supporting plate is connected to a rotating shaft via a bracket, and the extending direction of the rotating shaft is parallel to the first direction; the two ends of the bracket are respectively fixedly connected to the supporting plate and the rotating shaft; when the rotating shaft rotates around its axis, it can drive the orientation of the corresponding supporting plate to change.

[0006] The two support plates are arranged in parallel along a first direction, the front side of the support plate is used to support the workpiece, and the back side is connected to the rotating shaft through the bracket, and the extension direction of the rotating shaft is parallel to the first direction; because the two ends of the bracket are respectively fixedly connected to the support plate and the rotating shaft, when the rotating shaft rotates around its axis, it can drive the support plate to rotate synchronously, so that the orientation of the support plate changes, which can adapt to U-shaped or V-shaped workpieces with different bending angles. There is no need to set different support devices one by one according to the bending angles, which improves the adaptability of the support device and avoids waste of resources.

[0007] In a preferred technical solution of the utility model, a first through hole for the rotation shaft to pass through is provided in the bracket, and the rotation shaft passes through the first through hole and is fixedly connected to the bracket.

[0008] In the present application, the inner diameter of the first through hole is equal to the outer diameter of the rotating shaft, and the two are fixedly connected. In order to facilitate the assembly of the two, the first through hole and the rotating shaft can be welded together, or adhered together; this can ensure that when the inner diameter of the first through hole is slightly larger than the outer diameter of the rotating shaft, the two can also be fixedly connected. The other end of the bracket is fixed in the bracket, and can be fixed by welding or other methods. In this way, it can be ensured that the bracket serves as a rigid connector between the support plate and the rotating shaft, so that the support plate and the bracket rotate together with the rotating shaft.

[0009] In a preferred technical solution of the utility model, the rotating shaft is fixed in the support frame, and a second through hole for the rotating shaft to pass through is provided on the top of the support frame. The rotating shaft passes through the second through hole and is rotatably connected to the support frame.

[0010] The support frame is installed in the assembly platform. The support frame can be a vertical structure, and its height is specifically set according to the height at which the workpiece needs to be placed. A second through hole is set at the top of the support frame, and the second through hole is used to accommodate the rotating shaft. When the rotating shaft rotates, the support frame is fixed, so the inner diameter of the second through hole has no fixing effect on the rotating shaft; the inner diameter of the second through hole can be set to be larger than the outer diameter of the rotating shaft to ensure that the second through hole will not generate resistance to the rotating shaft during the rotation of the rotating shaft, ensuring that the rotating shaft rotates smoothly.

[0011] In a preferred technical solution of the utility model, a third through hole is provided in the support frame, the third through hole is communicated with the second through hole, a locking assembly is provided in the third through hole, and the locking assembly can lock or loosen the rotating shaft.

[0012] The number of support frames in the present application is at least two, which are used to limit and support the rotating shaft from both ends of the rotating shaft. Or the number of supports can also be multiple, evenly distributed along the length direction of the rotating shaft, and used to limit and support various positions of the rotating shaft. In the present application, there can be one third through hole, which can be set in one of the support frames. It is only necessary to limit a certain position of the rotating shaft to ensure that the position of the rotating shaft is fixed. Specifically, a third through hole is set in one of the support frames, and the third through hole is connected to the second through hole. The locking assembly passes through the third through hole and needs to abut against the rotating shaft. Only when the locking assembly abuts against the rotating shaft can the position of the rotating shaft be limited, ensuring that it will not rotate or deviate after rotating to a preset angle.

[0013] In a preferred technical solution of the utility model, the locking assembly includes a handle and a threaded connection part, and the third through hole is provided with an internal thread adapted to the threaded connection part; the handle is located at one end of the threaded connection part away from the third through hole.

[0014] When the handle drives the threaded connection part to pass through the third through hole and move toward the rotating shaft, the front end of the threaded connection part can abut the rotating shaft and limit the rotating shaft to be fixed in the second through hole, ensuring that the position and rotation angle of the rotating shaft remain unchanged. When the handle drives the threaded connection part to move in the third through hole in a direction away from the rotating shaft, the rotating shaft can move in the second through hole to achieve angle adjustment of the rotating shaft.

[0015] In a preferred technical solution of the utility model, the second through hole is surrounded by two semicircular notches, the semicircular notches are located in the auxiliary frame, the third through hole passes through the two auxiliary frames, and the locking assembly can lock or loosen the two auxiliary frames.

[0016] In the present application, the rotating shaft is fixed in the support frame, and the top of the support frame is provided with a second through hole for the rotating shaft to pass through, and the rotating shaft passes through the second through hole and is rotatably connected with the support frame. A second through hole is provided at the top of the support frame, and the second through hole is used to accommodate the rotating shaft. When the rotating shaft rotates, the support frame is fixed, so the inner diameter of the second through hole has no fixing effect on the rotating shaft; the inner diameter of the second through hole can be set to be larger than the outer diameter of the rotating shaft to ensure that the second through hole will not generate resistance to the rotating shaft during the rotation of the rotating shaft, so as to ensure that the rotating shaft rotates smoothly.

[0017] In a preferred technical solution of the utility model, the locking assembly includes a handle, a threaded connection part and a fastener, and the third through hole is provided with an internal thread adapted to the threaded connection part; the handle and the fastener are respectively located at two ends of the threaded connection part.

[0018] After the threaded connection part passes through the third through hole, it is connected to the fastener, and the fastener can be a structure such as a nut. The function of the handle is to limit one end of the threaded connection part to one side of the third through hole, and the fastener is installed at the other end of the threaded connection part. When the fastener is tightened, the locking assembly fixes the two auxiliary frames together. The degree of mold closing of the second through hole can be controlled by the tightness of the fastener, thereby ensuring that the gaps in the two auxiliary frames surround the second through hole and limit the rotating shaft. When the fastener is loosened, the two auxiliary frames are separated, the aperture of the second through hole becomes larger, and the rotating shaft can be rotated relative to the second through hole to achieve angle adjustment of the rotating shaft.

[0019] In a preferred technical solution of the present invention, at least one support frame is connected to a sliding drive member, and the sliding drive member can drive the support frame to move in a direction away from or close to another support plate.

[0020] In the present application, there may be one or two sliding drive members, and the position of only one of the support plates may be adjusted, or the positions of both support plates may be adjusted at the same time; the position adjustment here refers to the position adjustment of the two support plates being relatively close or relatively far away. When the distance between the two support plates changes, the corresponding size of the workpiece supported by the support device is also different. In the present application, the adjustment of the distance between the support plates can adapt to U-shaped or V-shaped workpieces of different lengths, and there is no need to set different support devices corresponding to the length of the workpiece, which improves the adaptability of the support device and avoids waste of resources.

[0021] A second object of the present utility model is to provide an assembly production line for an evaporator, comprising a supporting device as described above.

[0022] The use of an angle-adjustable support device to support the evaporator can ensure that during the assembly of evaporators of different models and sizes, there is no need to switch the support device, thereby improving the assembly efficiency of the evaporator.

[0023] The third object of the utility model is to provide a method for supporting a workpiece using a supporting device as described above, comprising:

[0024] Determine the angle between the two support plates according to the structure of the workpiece;

[0025] The rotating shaft is rotated around the center line of the rotating shaft, and the rotating shaft drives the direction of the supporting plate to change through the bracket, so that the angle between the two supporting plates is adapted to the angle of the workpiece;

[0026] The workpiece is placed between two support plates to support the workpiece.

[0027] The rotating shaft can drive the support plate to rotate, so that the orientation of the support plate changes, so that it can adapt to U-shaped or V-shaped workpieces with different bending angles. There is no need to set different support devices corresponding to the bending angles, which improves the adaptability of the support device and avoids waste of resources.

[0028] The beneficial effects of the utility model are:

[0029] The utility model provides a supporting device, wherein two supporting plates are arranged in parallel along a first direction, the front side of the supporting plate is used to support the workpiece, and the back side is connected to the rotating shaft through a bracket, and the extending direction of the rotating shaft is parallel to the first direction; because the two ends of the bracket are respectively fixedly connected to the supporting plate and the rotating shaft, when the rotating shaft rotates around its axis, it can drive the supporting plate to rotate synchronously, so that the orientation of the supporting plate changes, so that it can adapt to U-shaped or V-shaped workpieces with different bending angles, and there is no need to set different supporting devices one by one according to the bending angles, which improves the adaptability of the supporting device and avoids waste of resources.

[0030] The utility model also provides an evaporator assembly production line, including the supporting device as described above; the use of an angle-adjustable supporting device to support the evaporator can ensure that during the assembly process of evaporators of different models and sizes, there is no need to switch the supporting device, thereby improving the assembly efficiency of the evaporator.

[0031] The utility model also provides a method for supporting a workpiece, which comprises determining the angle between two support plates according to the structure of the workpiece; rotating the shaft around the center line of the shaft, and driving the direction of the support plates to change through the bracket, so that the angle between the two support plates is adapted to the angle of the workpiece; placing the workpiece between the two support plates to support the workpiece; the shaft can drive the support plates to rotate, so that the direction of the support plates changes, so that U-shaped or V-shaped workpieces with different bending angles can be adapted, and it is no longer necessary to set different support devices corresponding to the bending angles, thereby improving the adaptability of the support devices and avoiding waste of resources.

[0043] Example 1

[0044] like Figure 1-Figure 6 As shown, a supporting device comprises two supporting plates 11 arranged parallel to a first direction, one end surface of the supporting plate 11 is used to support a workpiece, and the other end surface of the supporting plate 11 is connected to a rotating shaft 13 through a bracket 12, and the extension direction of the rotating shaft 13 is parallel to the first direction; the two ends of the bracket 12 are respectively fixedly connected to the supporting plate 11 and the rotating shaft 13; when the rotating shaft 13 rotates around its axis, it can drive the orientation of the corresponding supporting plate 11 to change.

[0045] In the present application, the number of rotating shafts 13 can correspond to the number of supporting plates 11, that is, each supporting plate 11 is connected to a rotating shaft 13 through a bracket 12, or the rotating shaft 13 can be set in only one of the supporting plates 11. When there are two rotating shafts 13, the two rotating shafts 13 drive the two supporting plates 11 to rotate synchronously for angle adjustment, so that the two supporting plates 11 can always maintain a symmetrical state, and the center of the U-shaped or V-shaped workpiece falls in the middle of the two supporting plates 11, ensuring that the workpiece is placed stably.

[0046] When only one support plate 11 is installed with the rotating shaft 13, the direction of the support plate 11 can be rotated, and the direction of the other support plate 11 is constant, for example, the direction of the other support plate 11 is always upward. When the workpiece is a horizontal workpiece, the rotating shaft 13 drives the support plate 11 to rotate in the upward direction. At this time, the two upward support plates 11 are used to support the horizontal workpiece. When the workpiece angle is 90°, the rotating shaft 13 drives the support plate 11 to rotate in the vertical direction. At this time, the angle between the two support plates 11 is 90°, and the two support plates 11 are used to support the workpiece with an angle of 90°.

[0047] It should be noted that: when only one support plate 11 can rotate, during the rotation of the support plate 11, the two support plates 11 cannot always be in a symmetrical state. At this time, the center of the workpiece will deviate from the center position of the two workpieces. In order to ensure the stable placement of the workpiece, it is necessary to use an external auxiliary fixing device to achieve stable fixation of the workpiece to avoid the center of the workpiece from shifting under the action of gravity, causing the workpiece to fall, etc.

[0048] In the present application, the support plate 11 is a planar plate-like structure, and the first direction can be the length direction of the support plate 11, that is, two support plates 11 are arranged side by side, and in the length direction, the two support plates 11 are parallel to each other. The support plate 11 is a rectangular parallelepiped structure, and the four corners of the support plate 11 are arc-shaped structures to avoid damage to the workpiece due to too sharp corners. When the workpiece is placed on the support plate 11, the length of the support plate 11 can be much larger than the length of the workpiece, so that multiple workpieces of the same model can be placed in the same support device at the same time.

[0049] In the present application, the two ends of the bracket 12 are respectively fixedly connected to the support plate 11 and the rotating shaft 13, and the bracket 12 needs to be fixedly connected to the support plate 11 and needs to be fixedly connected to the rotating shaft 13. When the rotating shaft 13 rotates, the bracket 12, the support plate 11 and the rotating shaft 13 are an integrated structure and keep rotating synchronously. The axis of the rotating shaft 13 and the length of the support plate 11 extend in the same direction. The rotation of the rotating shaft 13 will drive the support plate 11 to rotate with the axis of the rotating shaft 13 as the center of the circle, thereby changing the angle between the two support plates 11 to adapt to workpieces with different angles.

[0050] In the present application, two support plates 11 are arranged in parallel along a first direction, the front side of the support plate 11 is used to support the workpiece, and the back side is connected to the rotating shaft 13 through the bracket 12, and the extension direction of the rotating shaft 13 is parallel to the first direction; because the two ends of the bracket 12 are respectively fixedly connected to the support plate 11 and the rotating shaft 13, when the rotating shaft 13 rotates around its axis, it can drive the support plate 11 to rotate synchronously, so that the orientation of the support plate 11 changes, which can adapt to U-shaped or V-shaped workpieces with different bending angles, and there is no need to set different support devices one by one according to the bending angles, which improves the adaptability of the support device and avoids waste of resources.

[0051] Example 2

[0052] like Figure 1-Figure 6 As shown, a supporting device comprises two supporting plates 11 arranged parallel to a first direction, one end surface of the supporting plate 11 is used to support a workpiece, and the other end surface of the supporting plate 11 is connected to a rotating shaft 13 through a bracket 12, and the extension direction of the rotating shaft 13 is parallel to the first direction; the two ends of the bracket 12 are respectively fixedly connected to the supporting plate 11 and the rotating shaft 13; when the rotating shaft 13 rotates around its axis, it can drive the orientation of the corresponding supporting plate 11 to change.

[0053] This embodiment is described by taking the case where there are two rotating shafts 13 as an example. When there is only one rotating shaft 13 , it is only necessary to omit the rotating shaft 13 structure of one of the supporting plates 11 .

[0054] In the present application, the bracket 12 is provided with a first through hole for the rotating shaft 13 to pass through, and the rotating shaft 13 passes through the first through hole and is fixedly connected to the bracket 12 .

[0055] In the present application, the inner diameter of the first through hole is equal to the outer diameter of the rotating shaft 13, and the two are fixedly connected. In order to facilitate the assembly of the two, the first through hole and the rotating shaft 13 can be welded together, or adhered together; this can ensure that when the inner diameter of the first through hole is slightly larger than the outer diameter of the rotating shaft 13, the two can also be fixedly connected. The other end of the bracket 12 is fixed in the bracket 12, and can be fixed by welding or other methods. In this way, it can be ensured that the bracket 12 serves as a rigid connector between the support plate 11 and the rotating shaft 13, so that the support plate 11 and the bracket 12 rotate together with the rotating shaft 13.

[0056] In the present application, the rotating shaft 13 is fixed in the supporting frame 14 . A second through hole 15 for the rotating shaft 13 to pass through is provided on the top of the supporting frame 14 . The rotating shaft 13 passes through the second through hole 15 and is rotatably connected to the supporting frame 14 .

[0057] The support frame 14 is installed in the assembly platform. The support frame 14 can be a vertical structure, and its height is specifically set according to the height at which the workpiece needs to be placed. A second through hole 15 is provided at the top of the support frame 14, and the second through hole 15 is used to accommodate the rotating shaft 13. When the rotating shaft 13 rotates, the support frame 14 is fixed, so the inner diameter of the second through hole 15 has no fixing effect on the rotating shaft 13; the inner diameter of the second through hole 15 can be set to be larger than the outer diameter of the rotating shaft 13, to ensure that during the rotation of the rotating shaft 13, the second through hole 15 will not generate resistance to the rotating shaft 13, and ensure that the rotating shaft 13 rotates smoothly.

[0058] Since the outer diameter of the rotating shaft 13 is smaller than the second through hole 15, when the rotating shaft 13 rotates to a preset angle, a locking assembly is required to fix the position of the rotating shaft 13. Specifically, a third through hole is provided in the support frame 14, and the third through hole is communicated with the second through hole 15. A locking assembly is provided in the third through hole, and the locking assembly can lock or loosen the rotating shaft 13.

[0059] The number of the support frames 14 of the present application is at least two, which are used to limit and support the rotating shaft 13 from both ends of the rotating shaft 13. Alternatively, the number of the brackets 12 can also be multiple, evenly distributed along the length direction of the rotating shaft 13, and used to limit and support various positions of the rotating shaft 13. In the present application, there can be one third through hole, which can be set in one of the support frames 14. It is only necessary to limit a certain position of the rotating shaft 13 to ensure that the position of the rotating shaft 13 is fixed. Specifically, a third through hole is set in one of the support frames 14, and the third through hole is connected to the second through hole 15. The locking assembly passes through the third through hole and needs to abut against the rotating shaft 13. Only when the locking assembly abuts against the rotating shaft 13 can the position of the rotating shaft 13 be limited, ensuring that it will not rotate or deviate after rotating to a preset angle.

[0060] In order to facilitate the rotation of the rotating shaft 13 , the present application may set a rotating handle 21 at both ends of the rotating shaft 13 , and the rotating shaft 13 can be rotated by holding the rotating handle 21 , thereby driving the support plate 11 to rotate.

[0061] Specifically, the locking assembly in the present application includes a handle 16 and a threaded connection portion 17, and the third through hole is provided with an internal thread adapted to the threaded connection portion 17; the handle 16 is located at one end of the threaded connection portion 17 away from the third through hole.

[0062] When the handle 16 drives the threaded connection part 17 to pass through the third through hole and move toward the rotating shaft 13, the front end of the threaded connection part 17 can abut against the rotating shaft 13 and limit and fix the rotating shaft 13 in the second through hole 15, ensuring that the position and rotation angle of the rotating shaft 13 remain unchanged. When the handle 16 drives the threaded connection part 17 to move in the third through hole in a direction away from the rotating shaft 13, the rotating shaft 13 can move in the second through hole 15 to achieve the angle adjustment of the rotating shaft 13.

[0063] Example 3

[0064] like Figure 5 As shown, the present application can further improve the structure of the support frame 14 including the third through hole, and a second through hole 15 is set at the top of the support frame 14, and the second through hole 15 is surrounded by two opposite semicircles, and the two opposite semicircles are respectively located in the two auxiliary frames, and the third through hole passes through the two auxiliary frames at the same time and is not connected to the second through hole 15.

[0065] In the present application, the bracket 12 is provided with a first through hole for the rotating shaft 13 to pass through, and the rotating shaft 13 passes through the first through hole and is fixedly connected to the bracket 12 .

[0066] In the present application, the rotating shaft 13 is fixed in the support frame 14, and the top of the support frame 14 is provided with a second through hole 15 for the rotating shaft 13 to pass through, and the rotating shaft 13 passes through the second through hole 15 and is rotatably connected with the support frame 14. A second through hole 15 is provided at the top of the support frame 14, and the second through hole 15 is used to accommodate the rotating shaft 13. When the rotating shaft 13 rotates, the support frame 14 is fixed, so the inner diameter of the second through hole 15 has no fixing effect on the rotating shaft 13; the inner diameter of the second through hole 15 can be set to be larger than the outer diameter of the rotating shaft 13, to ensure that during the rotation of the rotating shaft 13, the second through hole 15 will not generate resistance to the rotating shaft 13, and ensure that the rotating shaft 13 rotates smoothly.

[0067] Since the outer diameter of the rotating shaft 13 is smaller than the second through hole 15, when the rotating shaft 13 rotates to a preset angle, a locking assembly is required to fix the position of the rotating shaft 13. Specifically, the second through hole 15 is surrounded by two semicircular notches, the semicircular notches are located in the auxiliary frame, the third through hole passes through the two auxiliary frames, and the locking assembly can lock or loosen the two auxiliary frames.

[0068] The function of the locking assembly is to bring the two auxiliary frames together or release them. When the two auxiliary frames are brought together, the semicircular notches in the two auxiliary frames fix the rotating shaft 13, and the rotating shaft 13 cannot rotate relatively. When the two auxiliary frames are separated, the second through hole 15 surrounded by the two semicircular notches cannot limit the rotating shaft 13, and the rotating shaft 13 can rotate relative to the support frame 14 and the auxiliary frames. Specifically, the two semicircular notches can be arc-shaped notches slightly smaller than the semicircle, and the radius of the two semicircular notches is equal to the radius of the rotating shaft 13. When the two auxiliary frames are locked on the rotating shaft 13 by the locking assembly, the second through hole 15 can be fixedly fitted with the rotating shaft 13; when the two auxiliary frames are released, the two parts in the second through hole 15 are separated, so that the rotating shaft 13 can rotate relative to the support frame 14.

[0069] Specifically, the locking assembly in the present application includes a handle 16, a threaded connection portion 17 and a fastener, and the third through hole is provided with an internal thread adapted to the threaded connection portion 17; the handle 16 and the fastener are respectively located at two ends of the threaded connection portion 17.

[0070] After the threaded connection part 17 passes through the third through hole, it is connected to the fastener, and the fastener can be a structure such as a nut. The function of the handle 16 is to limit one end of the threaded connection part 17 to one side of the third through hole, and the fastener is installed at the other end of the threaded connection part 17. When the fastener is tightened, the locking assembly fixes the two auxiliary frames together. The degree of mold closing of the second through hole 15 can be controlled by the tightness of the fastener, thereby ensuring that the gaps in the two auxiliary frames surround the second through hole 15 and limit the rotation shaft 13. When the fastener is loosened, the two auxiliary frames are separated, the aperture of the second through hole 15 becomes larger, and the rotation shaft 13 can be rotated relative to the second through hole 15 to achieve angle adjustment of the rotation shaft 13.

[0071] Example 4

[0072] like Figure 1-Figure 6 As shown, a support device comprises two support plates 11 arranged parallel to a first direction, one end face of the support plate 11 is used to support a workpiece, and the other end face of the support plate 11 is connected to a rotating shaft 13 through a bracket 12, and the extension direction of the rotating shaft 13 is parallel to the first direction; the two ends of the bracket 12 are respectively fixedly connected to the support plate 11 and the rotating shaft 13; when the rotating shaft 13 rotates around its axis, it can drive the direction of the corresponding support plate 11 to change. A first through hole is provided in the bracket 12 for the rotating shaft 13 to pass through, and the rotating shaft 13 passes through the first through hole and is fixedly connected to the bracket 12. The rotating shaft 13 is fixed in a support frame 14, and a second through hole 15 is provided on the top of the support frame 14 for the rotating shaft 13 to pass through, and the rotating shaft 13 passes through the second through hole 15 and is rotatably connected to the support frame 14.

[0073] In the present application, the rotating shaft 13 is fixedly connected to the support plate 11 through the bracket 12, and is rotatably connected to the support frame 14 through the second through hole 15, so that the rotation of the rotating shaft 13 can drive the support plate 11 to rotate. The orientation of the support plate 11 is changed, so that it can adapt to U-shaped or V-shaped workpieces with different bending angles, and it is no longer necessary to set different support devices corresponding to the bending angles, thereby improving the adaptability of the support device and avoiding resource waste.

[0074] In addition to the angle adjustment, in the present application, at least one support frame 14 is connected to a sliding drive member 18 , and the sliding drive member 18 can drive the support frame 14 to move in a direction away from or close to another support plate 11 .

[0075] In the present application, there can be one or two sliding drive members 18, which can adjust the position of only one of the support plates 11, or adjust the positions of both support plates 11 at the same time; the position adjustment here refers to the position adjustment of the two support plates 11 being relatively close or relatively far away. When the distance between the two support plates 11 changes, the corresponding size of the workpiece supported by the support device is also different. In the present application, the adjustment of the distance between the support plates 11 can adapt to U-shaped or V-shaped workpieces of different lengths, and there is no need to set different support devices corresponding to the length of the workpiece, which improves the adaptability of the support device and avoids waste of resources.

[0076] In the present application, the workpiece is preferably a U-shaped or V-shaped workpiece. For workpieces of different models and sizes, the bending angles of the workpieces are different, and the lengths of the workpieces are also different. The length here refers to the size between the two bending parts. In the prior art, for workpieces of different lengths, corresponding support devices are also required to achieve support. The present application adjusts the distance between the two support plates 11 by sliding the drive member 18, which can achieve the spacing adjustment between the two support plates 11, thereby adapting to the sizes of workpieces of different lengths.

[0077] Specifically, the sliding drive member 18 includes a slider 20 and a slide rail 19 . The slider 20 is located in the slide rail 19 . The extension direction of the slide rail 19 is perpendicular to the first direction. The support frame 14 is fixed in the slider 20 .

[0078] The present application can set the support frame 14 on the slider 20. When the slider 20 moves along the slide rail 19, the support frame 14, the rotating shaft 13 and the support plate 11 move synchronously along the slide rail 19 as a whole. This structure can improve the convenience of adjusting the distance between the two support plates 11.

[0079] In the present application, the slider 20 slides along the slide rail 19 to a preset position, that is, when the relative distance between the two support plates 11 is determined, a fixing member can be set on the slide rail 19, and a sliding handle 22 is set at the end of the fixing member. The sliding handle 22 is held and driven to fix the position of the slider 20.

[0080] The fixing parts in the present application can be fastening components such as bolts and nuts for fastening and loosening the slider 20 and the slide rail 19, or clamping components that can fasten and loosen the slider 20 and the slide rail 19; or other limiting components that can limit the position of the slider 20.

[0081] Example 5

[0082] The present application provides an evaporator assembly production line, comprising the support device as described above. The evaporator is an evaporator used in a circular series cabinet. In order to adapt to the circular cabinet, the bending angle of the evaporator is between 60° and 110°. The support device is located on the side of the assembly production line, and is used to place the evaporator, and then the evaporator and the cabinet are assembled through the production line.

[0083] like Figure 1-Figure 6 As shown, the support device includes two support plates 11 arranged parallel to a first direction, one end surface of the support plate 11 is used to support a workpiece, and the other end surface of the support plate 11 is connected to a rotating shaft 13 through a bracket 12, and the extension direction of the rotating shaft 13 is parallel to the first direction; the two ends of the bracket 12 are respectively fixedly connected to the support plate 11 and the rotating shaft 13; when the rotating shaft 13 rotates around its axis, it can drive the direction of the corresponding support plate 11 to change. A first through hole is provided in the bracket 12 for the rotating shaft 13 to pass through, and the rotating shaft 13 passes through the first through hole and is fixedly connected to the bracket 12. The rotating shaft 13 is fixed in the support frame 14, and a second through hole 15 is provided on the top of the support frame 14 for the rotating shaft 13 to pass through, and the rotating shaft 13 passes through the second through hole 15 and is rotatably connected to the support frame 14.

[0084] In the present application, the rotating shaft 13 is fixedly connected to the support plate 11 through the bracket 12, and is rotatably connected to the support frame 14 through the second through hole 15, so that the rotation of the rotating shaft 13 can drive the support plate 11 to rotate. The orientation of the support plate 11 is changed, so that it can adapt to U-shaped or V-shaped workpieces with different bending angles, and it is no longer necessary to set different support devices corresponding to the bending angles, thereby improving the adaptability of the support device and avoiding resource waste.

[0085] In the present application, at least one support frame 14 is connected to a sliding drive member 18 , and the sliding drive member 18 can drive the support frame 14 to move in a direction away from or close to another support plate 11 .

[0086] In the present application, there can be one or two sliding drive members 18, which can adjust the position of only one of the support plates 11, or adjust the positions of both support plates 11 at the same time; the position adjustment here refers to the position adjustment of the two support plates 11 being relatively close or relatively far away. When the distance between the two support plates 11 changes, the corresponding size of the workpiece supported by the support device is also different. In the present application, the adjustment of the distance between the support plates 11 can adapt to U-shaped or V-shaped workpieces of different lengths, and there is no need to set different support devices corresponding to the length of the workpiece, which improves the adaptability of the support device and avoids waste of resources.

[0087] The support plate 11 for placing the bent portion of the evaporator has a width of 70 mm and a length of 800 mm, which can adapt to the straight side section size of all current circular evaporators.

[0088] The rotation angle of the rotating shaft 13 can achieve an angle flip of more than 180°, and cooperate with the locking component to achieve adjustment and fixation at different angles. It can adapt to the bending angles of all current circular evaporators.

[0089] In this embodiment, one of the support plates 11 is fixed, and the other is arranged on a slide block 20 that can slide along a slide rail 19. The slide rail 19 can be adjusted to a length interval of 160 mm, and with the minimum design interval of 100 mm, a maximum interval of 260 mm can be achieved. It can adapt to the length dimensions of all current circular evaporators.

[0090] Example 6

[0091] The present application also provides a method for a support device to support a workpiece, comprising:

[0092] The angle between the two support plates 11 is determined according to the structure of the workpiece. The specific workpiece may be a circular evaporator. The spacing between the two support plates 11 and the angle between the two support plates 11 are determined according to the model and size of the circular evaporator, and then the rotation position of the rotating shaft 13 and the position of the slider 20 in the slide rail 19 are determined.

[0093] The rotating shaft 13 is rotated around the center line of the rotating shaft 13, and the rotating shaft 13 drives the support plate 11 to change its orientation through the bracket 12, so that the angle between the two support plates 11 is adapted to the angle of the workpiece; when the support plate 11 is rotated to a preset orientation, the locking assembly locks the rotating shaft 13 to prevent the rotating shaft 13 from angular deviation.

[0094] The sliding drive member 18 drives the slider 20 to slide along the slide rail 19, so that the distance between the two support plates 11 reaches a preset value, and the slider 20 is fixed by a fixing member to prevent the slider 20 from being offset.

[0095] At this time, the included angle and distance between the two support plates 11 match the bending angle and length of the workpiece, and the workpiece can be placed between the two support plates 11 .
