[0001] This invention relates to the field of air conditioner manufacturing technology, and more specifically, to a support device. Background Technology

[0002] Currently, there are many air conditioner heat exchangers produced by non-shrink tube expansion machines. During the production process, the copper tubes of the air conditioner heat exchangers need to be placed on a special receiving base for processing.

[0003] However, due to the large number of models of air conditioner heat exchangers, the existing receiver can only produce heat exchangers of the corresponding specifications, resulting in low versatility. If the specifications and dimensions of the air conditioner heat exchanger are changed, it is very easy for the clamps of the air conditioner heat exchanger and the receiver to interfere with each other, making it impossible to produce air conditioner heat exchangers normally. Summary of the Invention

[0004] The main objective of this invention is to provide a support device to solve the problem of low versatility of the receiver sockets for air conditioners in the prior art.

[0006] Furthermore, the bearing device also includes: a transmission seat, at least a portion of which is disposed within the mounting cavity, the transmission seat being rotatably disposed about a predetermined axis, and a gripper disposed on the transmission seat, the gripper being rotated by the transmission seat.

[0007] Furthermore, the transmission seat includes: a transmission baffle, rotatably arranged around a predetermined axis, two transmission baffles respectively arranged on both sides of the mounting cavity; a connecting plate, the two ends of the connecting plate being connected to the two transmission baffles respectively, and a clamping claw arranged on the connecting plate.

[0008] Furthermore, the supporting device also includes: a drive assembly, at least a portion of which is movably arranged in the vertical direction; and a connecting crank, the two ends of which are respectively connected to the drive assembly and the transmission seat, the drive assembly driving the transmission seat to rotate through the connecting crank.

[0009] Furthermore, the transmission seat is provided with a connecting shaft: the connecting crank extends vertically, and the connecting crank is provided with a first connecting hole; the extension direction of the first connecting hole and the extension direction of the connecting crank are at an angle, and the connecting shaft passes through the first connecting hole so that the transmission seat can be driven to rotate by the limiting effect of the hole wall of the first connecting hole on the connecting shaft during the process of the connecting crank moving vertically.

[0010] Furthermore, the drive assembly includes: a push rod, which is movably disposed in the vertical direction; and a connecting rod, which is disposed at the pushing end of the push rod and is drivenly connected to the connecting crank.

[0011] Furthermore, the drive assembly also includes: a push block, which is disposed at the drive end of the push rod, and a connecting rod connected to the push block; and an elastic component, which is sleeved on the push rod, with its two ends connected to the push block and the push rod respectively, and the push rod is pushed downward by the elastic restoring force of the elastic component.

[0012] Furthermore, the bearing device also includes: a mounting bracket, a bearing base disposed at the end of the mounting bracket, a drive assembly disposed on the mounting bracket, and a connecting crank disposed on the side of the mounting bracket; wherein, the connecting crank is provided with a second through hole extending in a vertical direction, and a limiting protrusion is provided on the side of the mounting bracket, at least a portion of the limiting protrusion passing through the second through hole.

[0013] Furthermore, the support base includes: a protruding plate disposed on the inner wall surface of the mounting cavity, the protruding plate extending along an arcuate trajectory from the inner wall surface of the mounting cavity toward the center of the mounting cavity, and a supporting end face disposed on the protruding plate; wherein at least a portion of the gripper is opposite to the protruding plate.

[0014] Furthermore, the support base is also provided with a clearance notch that communicates with the mounting cavity. At least part of the clearance notch is opposite to the inner wall surface where the protruding plate is located, and the gripper is cleared through the clearance notch.

[0015] The technical solution of this invention includes a support base and grippers. The support base has a mounting cavity with a support end face for supporting the target workpiece. The grippers are rotatably disposed within the mounting cavity about a predetermined axis, and have a clamping position and a release position.

[0032] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0033] Existing support devices such as Figures 10 to 12 As shown, the support frame 100 is provided with two clamping plates 200. The two clamping plates 200 are arranged to be openable and closed to clamp or release the copper tube. When the size of the copper tube changes, the outer surface of the clamping plate 200 will protrude from the outer surface of the support frame 100, causing interference between the clamping plates 200 of two adjacent support frames 100. The same bearing device cannot be used for copper tubes of various sizes.

[0034] Please refer to Figures 1 to 9 The present invention provides a bearing device, comprising: a bearing base 1, wherein a mounting cavity 10 is provided in the bearing base 1, and a supporting end face 11 for supporting a target workpiece is provided in the mounting cavity 10; and a gripper 2, which is rotatably disposed in the mounting cavity 10 about a predetermined axis, the gripper 2 having a pressing position and a releasing position, at least a portion of the gripper 2 being in contact with the target workpiece so that the gripper 2 is in the pressing position; wherein the gripper 2 extends along an arcuate trajectory, and when the gripper 2 is in the pressing position or the releasing position, the outer surface of the bearing base 1 is tangent to the outer peripheral surface of the gripper 2.

[0035] The bearing device provided by the present invention includes a bearing base 1 and a gripper 2. The bearing base 1 has a mounting cavity 10, and the mounting cavity 10 has a supporting end face 11 for supporting a target workpiece. The gripper 2 is rotatably disposed within the mounting cavity 10 about a predetermined axis. The gripper 2 has a clamping position and a releasing position. At least a portion of the gripper 2 is in contact with the target workpiece, so that the gripper 2 is in the clamping position. The gripper 2 extends along an arcuate trajectory. When the gripper 2 is in the clamping or releasing position, the outer surface of the bearing base 1 is tangent to the outer peripheral surface of the gripper 2. By placing the gripper 2 within the mounting cavity 10 to clamp or release the target workpiece, and ensuring that the plane containing the outer surface of the bearing base 1 is tangent to the outer peripheral surface of the gripper 2, even when different sized target workpieces are used, the range of the gripper 2 is confined within the mounting cavity 10, and the gripper 2 will not interfere with other adjacent components of the bearing device, thus improving the versatility of the bearing device.

[0036] Specifically, the bearing device further includes: a transmission seat 3, at least a portion of which is disposed within the mounting cavity 10. The transmission seat 3 is rotatably disposed about a predetermined axis, and the gripper 2 is disposed on the transmission seat 3, driving the gripper 2 to rotate via the transmission seat 3. This configuration is simple and easy to implement, allowing the gripper 2 to switch between a clamping position and a releasing position by rotating.

[0037] In specific implementation, the transmission seat 3 includes: a transmission baffle 30, rotatably arranged around a predetermined axis, with two transmission baffles 30 respectively disposed on both sides of the mounting cavity 10; a connecting plate 31, with both ends of the connecting plate 31 connected to the two transmission baffles 30 respectively; and a clamping jaw 2 disposed on the connecting plate 31. The clamping jaw 2 is disposed in the middle of the connecting plate 31. Taking the copper pipe of an air conditioner as an example, the target workpiece of this application has a U-shaped portion that engages with the clamping jaw 2. By disposing of the clamping jaw 2 in the middle of the connecting plate 31, the transmission baffle 30 drives the clamping jaw 2 to rotate, thereby pressing the copper pipe.

[0038] Furthermore, the support device also includes: a drive assembly 4, at least a portion of which is movably arranged in the vertical direction; and a connecting crank 5, both ends of which are connected to the drive assembly 4 and the transmission seat 3 respectively, wherein the drive assembly 4 drives the transmission seat 3 to rotate via the connecting crank 5. This arrangement saves installation space and makes the overall structure of the support device more compact.

[0039] In this application, a connecting shaft 32 is provided on the transmission base 3; a connecting crank 5 extends vertically, and a first connecting hole 50 is provided on the connecting crank 5; the extension direction of the first connecting hole 50 forms an angle with the extension direction of the connecting crank 5, and the connecting shaft 32 passes through the first connecting hole 50 so that, during the vertical movement of the connecting crank 5, the limiting effect of the hole wall of the first connecting hole 50 on the connecting shaft 32 drives the transmission base 3 to rotate. Thus, when the connecting crank 5 moves vertically, since the extension direction of the first connecting hole 50 is inclined relative to the extension direction of the connecting crank 5, the blocking effect of the hole wall of the first connecting hole 50 on the connecting shaft 32 causes the connecting shaft 32 to drive the transmission base 3 to rotate. Preferably, the connecting shaft 32 is provided on the transmission baffle 30. There are two connecting cranks 5, and the two connecting cranks 5 respectively cooperate with the two transmission baffles 30.

[0040] In the embodiment provided by the present invention, the driving assembly 4 includes: a push rod 40, which is movably arranged in the vertical direction; and a connecting rod 41, which is disposed at the pushing end of the push rod 40 and is drivingly connected to the connecting crank 5. The push rod 40 extends in the vertical direction, and the connecting rod 41 extends in the horizontal direction. Both ends of the connecting rod 41 are respectively connected to two connecting cranks 5, so that the push rod 40 simultaneously drives the two connecting cranks 5 to move via the connecting rod 41.

[0041] Furthermore, the drive assembly 4 also includes: a push block 42, disposed at the drive end of the push rod 40, with the connecting rod 41 connected to the push block 42; and an elastic member 43, sleeved on the push rod 40, with both ends of the elastic member 43 connected to the push block 42 and the push rod 40 respectively. The elastic restoring force of the elastic member 43 pushes the push rod 40 downward. The push block 42 provides resistance to the elastic member 43. Preferably, the elastic member 43 is a spring. The piston rod drives the push rod 40 upward. When the push rod 40 moves upward to its limit position, the elastic member 43 compresses to a predetermined position, and then the elastic restoring force of the elastic member 43 pushes the push rod 40 downward.

[0042] In a specific implementation, the supporting device further includes: a mounting bracket 6, a supporting base 1 disposed at the end of the mounting bracket 6, a drive assembly 4 disposed on the mounting bracket 6, and a connecting crank 5 disposed on the side of the mounting bracket 6; wherein, the connecting crank 5 is provided with a second through hole 51, the second through hole 51 extending vertically, and a limiting protrusion 60 is provided on the side of the mounting bracket 6, at least a portion of the limiting protrusion 60 passing through the second through hole 51. Preferably, the mounting bracket 6 is a hollow structure, the push rod 40 is disposed inside the mounting bracket 6, the connecting crank 5 is disposed on the side of the mounting bracket 6, and the side of the mounting bracket 6 is also provided with a through hole 61, through which the connecting rod 41 is connected to the connecting crank 5. This arrangement hides most of the structure of the drive assembly 4 inside the mounting bracket 6, avoiding interference between the supporting device and other adjacent components, making the overall structure more compact.

[0043] In this application, the support base 1 includes: an extension plate 12 disposed on the inner wall surface of the mounting cavity 10, the extension plate 12 extending along an arcuate trajectory from the inner wall surface of the mounting cavity 10 toward the center of the mounting cavity 10, and a supporting end face 11 disposed on the extension plate 12; wherein at least a portion of the gripper 2 is opposite to the extension plate 12. The copper tube is supported by the extension plate 12.

[0044] Furthermore, the support base 1 is also provided with a clearance notch 13 communicating with the mounting cavity 10. At least a portion of the clearance notch 13 is opposite to the inner wall surface where the protruding plate 12 is located, and the clearance notch 13 avoids the gripper 2. This arrangement avoids mutual interference between the inner wall surface of the mounting cavity 10 and the gripper 2. The clearance notch 13 increases the rotation stroke of the gripper 2, which also allows the clamping force of the gripper 2 to be adjusted according to different sizes of copper tubes. When the rotation range of the gripper 2 is large, the clamping force on the copper tube increases, and vice versa. The gripper 2 is designed with an arc-shaped trajectory extension so that the clamping surface of the gripper 2 matches the surface of the copper tube, preventing damage to the copper tube and ensuring that the copper tube can be clamped on the support device without shrinkage during tube expansion production.

[0045] This application solves the problem of interference between load-bearing devices with varying heights and widths, and addresses the issue of interference between the clamping jaws and the lower plate due to an excessively narrow lower plate, preventing the jaws from opening. It also resolves the problem of interference between load-bearing devices caused by mixed straight and oblique insertion methods, which could not meet layout requirements and prevent the production of both devices. This enables universal production of both devices, reducing the need for additional special tooling or molds during debugging, minimizing the accumulation of errors in the intermediate process, and ensuring rapid changeover and equipment consistency.

[0046] As can be seen from the above description, the embodiments of the present invention achieve the following technical effects:

[0047] The bearing device provided by the present invention includes a bearing base 1 and a gripper 2. The bearing base 1 has a mounting cavity 10, and the mounting cavity 10 has a supporting end face 11 for supporting a target workpiece. The gripper 2 is rotatably disposed within the mounting cavity 10 about a predetermined axis. The gripper 2 has a clamping position and a releasing position. At least a portion of the gripper 2 is in contact with the target workpiece, so that the gripper 2 is in the clamping position. The gripper 2 extends along an arcuate trajectory. When the gripper 2 is in the clamping or releasing position, the outer surface of the bearing base 1 is tangent to the outer peripheral surface of the gripper 2. By placing the gripper 2 within the mounting cavity 10 to clamp or release the target workpiece, and ensuring that the plane containing the outer surface of the bearing base 1 is tangent to the outer peripheral surface of the gripper 2, even when different sized target workpieces are used, the range of the gripper 2 is confined within the mounting cavity 10, and the gripper 2 will not interfere with other adjacent components of the bearing device, thus improving the versatility of the bearing device.
