Technical Field
[0001] This utility model relates to the field of spiral condenser manufacturing and processing technology, specifically a manufacturing and processing fixture for a copper tube aluminum fin spiral condenser for household refrigerators. Background Technology
[0002] The copper tube and aluminum fin spiral condenser for refrigerators is a highly efficient heat exchange device widely used in modern refrigerator refrigeration systems. It uses copper tubes as the refrigerant conduits, with aluminum fins tightly wound around them to form a spiral structure. This design not only increases the heat dissipation area and improves heat exchange efficiency but also makes the condenser more compact and lightweight. Furthermore, the aluminum fins have excellent thermal conductivity and corrosion resistance, effectively transferring the heat released by the refrigerant to the surrounding air, thus achieving the refrigerator's cooling function. The spiral structure also makes the condenser easier and more flexible to install and use. During the production and processing of the copper tube and aluminum fin spiral condenser, appropriate tooling fixtures are often used to secure the workpiece and facilitate subsequent processing operations by the operator, in order to improve the overall operational stability of the mechanism.
[0003] During the use of tooling fixtures, when fixing coiled copper tubes, there are no other protective mechanisms to secure the tubes at different positions in stages. This results in only the outermost tubes being secured during the actual fixing operation, leaving the inner tubes prone to shaking during processing, thus affecting the processing quality. Therefore, a new technical solution is needed to address this issue. Utility Model Content
[0004] The purpose of this utility model is to overcome the shortcomings of the existing technology, adapt to the needs of reality, and provide a production and processing fixture for copper tube aluminum fin spiral condensers for household refrigerators. This fixture solves the technical problem that when fixing copper tubes that are wound together, there is no other protective mechanism to fix the copper tubes at different positions in stages. As a result, in actual fixing operations, only the outermost copper tubes are fixed, and the inner copper tubes are prone to shaking during processing, which affects the processing quality.
[0005] To achieve the purpose of this utility model, the technical solution adopted by this utility model is as follows: design a production and processing fixture for a copper tube aluminum fin spiral condenser for a household refrigerator, including a heat dissipation coil, a heat shrink tubing connected to the side of the heat dissipation coil, a buffer mechanism provided on the outside of the heat shrink tubing, and spiral fins fixedly sleeved on the side of the heat dissipation coil.
[0006] Both ends of the heat dissipation coil are provided with bottom brackets. Shock-absorbing pads are fixedly installed on the outer surface of the bottom brackets. Side brackets are detachably installed on both sides of the heat dissipation coil via first and second self-tapping screws. Fixed brackets are fixedly sleeved on the outer side of the heat dissipation coil, and there are several sets of fixed brackets. A wind baffle is fixedly installed on the outer wall of the heat dissipation coil.
[0007] Preferably, a fixing plate is movably attached to the outer side of the bottom of the heat dissipation coil, a hollow frame is fixedly installed at the bottom of the fixing plate, a synchronization mechanism is provided inside the hollow frame, clamping mechanisms are provided on both sides of the top of the fixing plate, and the synchronization mechanism and the clamping mechanism are connected in a driving manner, a snap-fit sliding frame is fixedly installed on both sides of the bottom of the hollow frame, a support platform is slidably snapped into the inner side of the snap-fit sliding frame, a drive mechanism is provided at the bottom of the support platform, and the drive mechanism is connected in a driving manner to the bottom of the snap-fit sliding frame, and support legs are vertically fixedly installed on the four corner surfaces of the bottom of the support platform.
[0008] Preferably, the synchronization mechanism includes a bidirectional lead screw. The bidirectional lead screw is installed laterally inside the hollow frame via bearings. A servo motor is fixedly installed on the side inside the hollow frame, and a servo motor is also fixedly installed on the side of the servo motor drive shaft. The side of the servo motor drive shaft is fixedly connected to the side of the bidirectional lead screw via a coupling. Both outer sides of the bidirectional lead screw are threadedly fitted with transmission sleeves. A connecting rod is vertically fixedly installed on the top of the outer side of each transmission sleeve. Limiting grooves are laterally opened on both sides of the top of the hollow frame, and the connecting rod is slidably inserted into the limiting groove.
[0009] Preferably, the clamping mechanism includes a support frame, and sliding plates are slidably installed on both sides of the top of the fixed plate. The top of the connecting rod and the bottom of the sliding plate are fixedly connected. A support frame is fixedly installed on the top surface of each sliding plate, and the side of the support frame is movably attached to the outer surface of the bottom support.
[0010] Preferably, the driving mechanism includes a transmission gear and a transmission gear ring. The transmission gear ring is fixedly installed between the bottom of the two sets of snap-fit sliding frames. A rotating motor is fixedly installed on the bottom side surface of the support platform. A transmission gear is fixedly sleeved on the outer side of the bottom of the rotating motor transmission shaft, and the outer side of the transmission gear meshes with the outer side of the transmission gear ring.
[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0012] 1. This utility model provides bottom and side supports on the outside of the coiled heat dissipation coil, allowing for processing support from the periphery. Multiple sets of fixed supports are also provided on the outside of the inner coil, preventing the inner coil from tilting or swaying during processing, thus ensuring stability and quality. Simultaneously, foam support blocks and shock absorbers are provided on the outside of the heat shrink tubing connected to the side of the heat dissipation coil. These provide cushioning and protection, preventing damage to the outermost heat shrink tubing from external impacts during processing, further improving the overall stability of the heat dissipation coil.
[0013] 2. This utility model, by setting a corresponding bidirectional lead screw at the bottom of the heat dissipation coil, combined with the rotational transmission action of the bidirectional lead screw on the transmission sleeve, allows two sets of transmission sleeves to move horizontally in opposite directions within the hollow frame. Then, under the connecting transmission action of the connecting rod, the sliding plate and its top support frame can move horizontally synchronously on the outside of the heat dissipation coil until the side of the support frame can fit against the outside of the heat dissipation coil for placement and restraint. Subsequently, combined with the meshing transmission action of the transmission gear and transmission gear ring, during the operation of the rotating motor, the transmission gear ring, connecting its top fixing plate and the heat dissipation coil placed on the surface, can rotate synchronously. This improves the clamping stability of the heat dissipation coil during placement and processing, facilitates the rotational adjustment of the processing position of the heat dissipation coil, and allows the operator to process different positions on the outside of the heat dissipation coil.

[0020] The present invention will be further described below with reference to the accompanying drawings and embodiments:
[0021] Example 1: A manufacturing fixture for a copper tube and aluminum fin spiral condenser for household refrigerators, see [link / reference]. Figures 1 to 5 The device includes a heat sink coil 1, with a heat shrink tubing 7 connected to its side. A buffer mechanism is provided on the outside of the heat shrink tubing 7. Spiral fins 15 are fixedly sleeved on the side of the heat sink coil 1. Bottom supports 2 are provided at both ends of the side of the heat sink coil 1. Shock-absorbing pads 8 are fixedly installed on the outer surface of the bottom supports 2. Side supports 4 are detachably installed on both vertical sides of the outside of the heat sink coil 1 through first self-tapping screws 5 and second self-tapping screws 6. Fixed supports 3 are fixedly sleeved on the outside of the heat sink coil 1, and there are several sets of fixed supports 3. A wind baffle 12 is fixedly installed on the outer wall of the heat sink coil 1. By providing multiple sets of bottom supports 2, side supports 4 and fixed supports 3 on the outside of the heat sink coil 1, the pipe located in the inner perimeter can be prevented from tilting and shaking arbitrarily during processing, thus affecting the processing stability and processing quality.
[0022] For details, see Figures 1 to 5 The buffer mechanism includes a foam support block 9 and a shock absorber block 10. Foam support blocks 9 are fixedly sleeved on both sides of the heat shrink tube 7. A shock absorber block 10 is fixedly sleeved on the side of the heat shrink tube 7 away from the foam support block 9. With the buffer protection of the heat shrink tube 7 by the foam support block 9 and the shock absorber block 10, the outermost heat shrink tube 7 will not be damaged by external impact, further improving the processing stability of the overall heat dissipation coil 1.
[0023] Example 2: It is worth noting that, see [link to example]. Figures 1 to 5A fixing plate 17 is movably attached to the outer bottom of the heat sink 1. A hollow frame 11 is fixedly installed at the bottom of the fixing plate 17. A synchronization mechanism is provided inside the hollow frame 11. Clamping mechanisms are provided on both sides of the top of the fixing plate 17, and the synchronization mechanism and the clamping mechanism are connected in a transmission. A snap-fit sliding frame 25 is fixedly installed on both sides of the bottom of the hollow frame 11. A support platform 20 is slidably snapped onto the inner side of the snap-fit sliding frame 25. A driving mechanism is provided at the bottom of the support platform 20, and the driving mechanism is connected in a transmission to the bottom of the snap-fit sliding frame 25. Support legs 21 are vertically fixedly installed on the four corner surfaces of the bottom of the support platform 20. Under the driving action of the synchronization mechanism on the clamping mechanism and the driving action of the driving mechanism on the rotation of the fixing plate 17, the clamping stability of the heat sink 1 during placement and processing is improved. At the same time, it is convenient to rotate and adjust the processing position of the heat sink 1, and it is convenient for the operator to process different positions on the outside of the heat sink 1.
[0024] It is worth noting that, see Figures 1 to 5 The synchronization mechanism includes a bidirectional lead screw 13. The bidirectional lead screw 13 is installed laterally inside the hollow frame 11 via bearings. A servo motor 26 is fixedly installed on the side inside the hollow frame 11, and a servo motor 26 is fixedly installed on the side of its transmission shaft. The side of the transmission shaft of the servo motor 26 is fixedly connected to the side of the bidirectional lead screw 13 via a coupling. Both sides of the bidirectional lead screw 13 are threadedly fitted with transmission sleeves 14. A connecting rod 16 is vertically fixedly installed on the top of the outer side of each transmission sleeve 14. Limiting grooves 27 are laterally opened on both sides of the top of the hollow frame 11, and the connecting rod 16 slides through and is inserted into the limiting grooves 27. Under the rotational transmission action of the bidirectional lead screw 13 on the transmission sleeves 14, when the bidirectional lead screw 13 rotates, the transmission sleeves 14 can drive the sliding plate 18 to move synchronously and horizontally towards each other on the outside of the heat sink 1, thereby adjusting the distance between the sliding plate 18 and the support frame 19.
[0025] It is worth noting that, see Figures 1 to 5 The clamping mechanism includes a support frame 19. Sliding plates 18 are slidably installed on both sides of the top of the fixed plate 17. The top of the connecting rod 16 is fixedly connected to the bottom of the sliding plate 18. A support frame 19 is fixedly installed on the top surface of each sliding plate 18. The side of the support frame 19 is movably attached to the outer surface of the bottom bracket 2. The triangular support frame 19 on the top of the sliding plate 18 allows the sliding plate 18 to drive the support frame 19 to move horizontally synchronously, thereby clamping and fixing the heat dissipation coil 1 placed on the surface of the fixed plate 17.
[0026] It is worth noting that, see Figures 1 to 5The driving mechanism includes a transmission gear 23 and a transmission gear ring 24. The transmission gear ring 24 is fixedly installed between the bottoms of the two sets of snap-fit sliding frames 25. The outer side of the transmission gear ring 24 is provided with a tooth block that meshes with the transmission gear 23. The bottom side surface of the support platform 20 is fixedly installed with a rotating motor 22. The transmission gear 23 is fixedly sleeved on the outer side of the bottom of the transmission shaft of the rotating motor 22, and the outer side of the transmission gear 23 meshes with the outer side of the transmission gear ring 24. Under the meshing transmission action of the transmission gear ring 24 and the transmission gear 23, and driven by the rotating motor 22, the two sets of snap-fit sliding frames 25 and the fixed plate 17 on their tops can be driven to rotate synchronously. This facilitates the rotation and adjustment of the processing position of the heat sink 1, and also facilitates the operator to process different positions on the outer side of the heat sink 1.
[0027] During operation, bottom brackets 2 are installed at both ends of the outer side of the spiral condenser coil 1 to be fixed. Simultaneously, side brackets 4 are installed at both ends of the outer side of the coil 1 using first automatic screws and second self-tapping screws 6. Then, fixed brackets 3 and baffles 12 are simultaneously installed on the outer side of the coil 1, which is wound around the inner side of multiple sets of coils. The bottom brackets 2, side brackets 4, and fixed brackets 3 together provide support for the entire coil 1. Finally, foam support blocks 9 and shock absorbers 10 are fitted onto the sides of the coil 1. After the heat shrink tubing 7 is placed on the outside, the foam support block 9 and the shock absorber block 10 can provide support, buffering and protection for the outside of the heat shrink tubing 7. Then, the middle part of the heat sink 1 is placed on the top surface of the fixing plate 17, so that the two sets of support frames 19 can be located on both sides of the outer middle of the bottom bracket 2 of the heat sink 1. The servo motor 26 is turned on by the external control switch, so that it drives the bidirectional lead screw 13 to rotate synchronously inside the hollow frame 11. Combined with the rotation transmission action of the bidirectional lead screw 13 on the transmission sleeve 14, and the guide and limit of the connecting rod 16 by the limit slide groove 27, the connecting rod 16 is also controlled by the limit slide groove 27. Under the action of the connecting rod 16, the two sets of transmission sleeves 14 can move horizontally towards each other inside the hollow frame 11, and then, under the connecting transmission action of the connecting rod 16, can provide a corresponding pushing force to the sliding plate 18, so that the sliding plate 18 and the support frame 19 can move horizontally towards each other at both ends of the outer side of the heat dissipation coil 1, until the side of the support frame 19 is attached to the outer side of the bottom bracket 2 and then subjected to abutment and limiting treatment, so that the bottom bracket 2 and the heat dissipation coil 1 can be stably clamped and fixed. While processing the heat dissipation coil 1, through the external The control switch turns on the rotating motor 22, causing it to rotate and drive the transmission gear 23 to rotate. Under the meshing transmission action of the transmission gear 23 and the transmission gear ring 24 located on the outside, the transmission gear ring 24 can be driven to rotate synchronously inside the support platform 20. Then, under the connection action of the snap-fit sliding frame 25, it provides the hollow frame 11 and the fixed plate 17 with the corresponding rotation driving force, so that the fixed plate 17 and the heat dissipation coil 1 placed on its surface rotate synchronously, thereby rotating and changing the processing position, and realizing the overall processing of the heat dissipation coil 1.
