Description

Technical Field

[0001] This utility model relates to the field of copper tube support frames, and more particularly to a copper tube support frame used in refrigerator production lines. Background Technology

[0002] During the refrigerator assembly process, multiple different copper pipes need to be assembled and laid on the refrigerator. These copper pipes are usually bent into shape on the bending production line and then suspended on a specific support frame. The support frame then transports the copper pipes to the side of the assembly line for workers to install.

[0003] During the assembly process, because the existing copper pipe support frame is fixed in position and cannot be moved automatically, workers need to constantly move around and actively approach the copper pipe to remove it from the support frame for installation. As the nearest copper pipe is used up, workers need to move to more distant positions to remove it, which increases the number of times workers need to move, increases labor intensity, and decreases work efficiency. Utility Model Content

[0004] To overcome the shortcomings of existing technologies, the purpose of this utility model is to provide a copper tube support frame for refrigerator production lines. This frame can automatically rotate the loaded copper tubes during assembly, allowing the copper tubes to move closer to the workers without requiring frequent movement, thus reducing labor intensity and improving efficiency. Furthermore, the spacing of the copper tube frame can be adjusted according to the length of the copper tubes, enhancing ease of use.

[0005] To address the problems in the existing technology, the technical solution of this utility model is as follows:

[0006] A copper tube support frame for use in a refrigerator production line includes a base, and a support rod is rotatably connected to the center of the top surface of the base;

[0007] Several copper tube supports are slidably sleeved on the outer side of the support rod. The copper tube supports can slide along the outer wall of the support rod in the axial direction of the support rod. The copper tube supports are positioned on the outer wall of the support rod by a snap-fit ​​assembly.

[0008] Preferably, a reinforcing frame is fixed at the center of the top surface of the base, the support rod passes through the top surface of the reinforcing frame, and the support rod is rotatably connected to the top surface of the reinforcing frame through a bearing.

[0009] Preferably, the top surface of the base is fixed with a rotating assembly that drives the support rod to rotate.

[0010] Preferably, the rotating assembly includes a motor fixed to the top surface of the base, the output end of the motor is connected to a worm gear, the worm gear is rotatably connected to the top surface of the base through a bearing, and a worm wheel is fixed to the lower end of the outer wall of the support rod, the worm wheel being meshed with the worm gear.

[0011] Preferably, the snap-fit ​​assembly includes a snap-fit ​​sleeve fixed to the outer wall of the copper tube frame. The axis of the snap-fit ​​sleeve is perpendicular to the axis of the support rod. A pin is slidably inserted into the inner wall of the snap-fit ​​sleeve. Both ends of the pin extend through the openings at both ends of the snap-fit ​​sleeve to the outer side of the snap-fit ​​sleeve. An annular first protrusion is formed on the outer wall of the inner side of the snap-fit ​​sleeve. A spring is sleeved on the outer side of the inner part of the snap-fit ​​sleeve. One end of the spring is in pressure contact with the outer wall of the first protrusion, and the other end of the spring is in pressure contact with the inner wall of the snap-fit ​​sleeve. The end of the pin near the outer wall of the copper tube frame is slidably connected to the copper tube frame through a sliding hole. Several slots are evenly spaced from top to bottom on the outer wall of the support rod near the pin. The end of the pin near the slot extends through the copper tube frame to the inner wall of the copper tube frame and snaps into one of the slots.

[0012] Preferably, the copper tube frame consists of a sliding sleeve that is slidably fitted on the outer wall of the support rod, an annular second protrusion formed at the middle position of the outer wall of the sliding sleeve, and a support rod fixed at equal angular intervals on the outer wall of the second protrusion. The end of the support rod away from the second protrusion has a semi-circular hook with an upward opening. The snap-fit ​​sleeve is fixed on the outer wall of the sliding sleeve, and the pin is slidably connected to the sliding sleeve through a sliding hole.

[0013] Compared with the prior art, the advantages of this utility model are as follows:

[0014] 1. This utility model, by setting a support rod that is rotatably connected to the base, installs the copper tube rack on the support frame. When the worker is assembling copper tubes on the assembly line, after each copper tube is picked up, the support frame is driven to rotate, so that the remaining copper tubes automatically rotate to a position close to the worker. In this way, the worker does not need to actively move to pick up copper tubes, which greatly reduces the labor intensity of the worker and improves work efficiency.

[0015] 2. This utility model slides the copper tube frame onto the support rod and uses a pin structure for positioning. When the refrigerator model being assembled changes or the size of the copper tube changes, the distance between two adjacent copper tube frames can be adjusted to a suitable size to ensure that the distance between two adjacent copper tube frames can accommodate the length of one copper tube. This allows the entire support frame to support multiple layers of copper tubes simultaneously, even when the copper tubes are short. Furthermore, if only one layer of copper tubes is being supported, the height of the loaded copper tubes can be adjusted to suit the physique of the assembly worker, greatly increasing adaptability and worker comfort.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] Please see Figures 1 to 3 This embodiment provides a copper tube support frame for refrigerator production line, including a base 1. A support rod 2 is rotatably connected to the center of the top surface of the base 1. A sliding sleeve 3 is slidably sleeved on the outer wall of the support rod 2. An annular second protrusion 301 is formed at the middle position of the outer wall of the sliding sleeve 3. A frame rod 4 is fixed at equal angular intervals on the outer wall of the second protrusion 301. A semi-circular hook 404 with an upward opening is formed at the end of the frame rod 4 away from the second protrusion 301.

[0022] After the copper tube is bent into shape at the bending station, it is suspended on the hook 404. After a copper tube is suspended on each support rod 4, the support rod 2 is driven to rotate, and the next support rod 4 is switched to the bending station to continue suspending copper tubes. Similarly, at the assembly station, after each copper tube is picked up, the support rod 2 is rotated to rotate the next support rod 4 to the assembly station. In both working cases, there is no need for workers to move to pick up and put down copper tubes, which reduces labor intensity and improves work efficiency.

[0023] A motor 5 is fixed on the top surface of the base 1. The output end of the motor 5 is connected to a worm gear 6. The worm gear 6 is rotatably connected to the top surface of the base 1 through a bearing. A worm wheel 7 is fixed at the lower end of the outer wall of the support rod 2. The worm wheel 7 is meshed with the worm gear 6. The rotation of the support rod 2 can drive the worm gear 6 to rotate through the drive motor 5, thereby driving the worm wheel 7 to rotate and thus driving the support rod 2 to rotate, completing the transmission work of the copper tube, so that the copper tube continuously reaches the assembly station.

[0024] A reinforcing frame 8 is fixed at the center of the top surface of the base 1. The support rod 2 passes through the top surface of the reinforcing frame 8 and is rotatably connected to the top surface of the reinforcing frame 8 through a bearing. The arrangement of the reinforcing frame 8 enables the support rod 2 to be installed more stably on the base 1, thereby greatly improving the stability of the support rod 2.

[0025] A snap-fit ​​sleeve 9 is fixed on the outer wall of the sliding sleeve 3. The axis of the snap-fit ​​sleeve 9 is perpendicular to the axis of the support rod 2. A pin 10 is slidably inserted into the inner wall of the snap-fit ​​sleeve 9. The two ends of the pin 10 extend through the openings at both ends of the snap-fit ​​sleeve 9 to the outer side of the snap-fit ​​sleeve 9. A first annular protrusion 1001 is formed on the outer wall of the inner side of the pin 10. A spring 11 is sleeved on the outer side of the inner part of the pin 10 in the snap-fit ​​sleeve 9. One end of the spring 11 is pressed against the outer wall of the first protrusion 1001, and the other end of the spring 11 is pressed against the inner wall of the snap-fit ​​sleeve 9. The end of the pin 10 near the outer wall of the sliding sleeve 3 is slidably connected to the sliding sleeve 3 through a sliding hole. Several slots 12 are opened at equal intervals from top to bottom on the outer wall of the support rod 2 near the pin 10. The end of the pin 10 near the slot 12 extends through the sliding sleeve 3 to the inner side of the sliding sleeve 3 and is snapped into one of the slots 12.

[0026] The distance between the upper and lower sliding sleeves 3 can be adjusted according to the length of the loaded copper tube. During adjustment, the pin 10 is pulled out of the slot 12 by pulling the pin 10. Then the sliding sleeve 3 can be moved up and down to adjust the height of the sliding sleeve 3 on the support rod 2. After the adjustment is appropriate, the pin 10 is released. Under the action of the spring 11, the pin 10 is pushed into the slot 12 to complete the limiting work of the sliding sleeve 3.

[0027] After the spacing between the upper and lower frame poles 4 is adjusted, copper pipes can be suspended on both the upper and lower frame poles 4, increasing the load-bearing capacity. If only the upper frame pole 4 needs to be loaded, the height of the upper frame pole 4 can be adjusted to suit the height of the assembly workers, improving adaptability.

[0028] In summary, this utility model can automatically drive all the copper pipes under its support to revolve around the axis of the support rod 2 when workers are performing assembly work. After the copper pipe near the worker's assembly position is used up, the next copper pipe can be automatically switched to the assembly position. There is no need for manual movement to pick up copper pipes, making the operation more convenient, saving manpower, and improving efficiency. In addition, the height of the support rod 4 is adjustable, and the spacing between the two adjacent support rods 4 is also adjustable, which greatly improves the adaptability of the entire support frame.

[0029] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
