Description

Technical Field

[0001] This utility model belongs to the field of radiator processing technology, specifically relating to a fixture for radiator production. Background Technology

[0002] In radiator manufacturing, the performance of machining fixtures is crucial to both production efficiency and quality. However, existing fixtures present significant problems. In terms of efficiency, they can only process one radiator at a time, leading to low efficiency in the face of increasing market demand. This results in longer production cycles, increased costs, and weakened product competitiveness. Furthermore, the fixtures suffer from poor fixation, complex and time-consuming processes, and unstable workpiece fixation. During machining, tool vibrations are transmitted to the workpiece, causing it to vibrate synchronously, affecting accuracy, scratching the surface, and producing defective products, resulting in economic losses. In addition, radiator insertion and removal are difficult and cannot be automated. In large-scale production, manual loading and unloading increases labor intensity, easily damages radiators, and cannot be integrated with automated production lines, limiting the improvement of production efficiency.

[0003] In summary, the shortcomings of existing clamps in terms of efficiency, fixation, and loading / unloading have become a constraint on the industry's development, and there is an urgent need to develop new clamps to solve these problems and promote industrial upgrading. Utility Model Content

[0004] The purpose of this utility model is to provide a fixture for radiator production, which aims to solve the technical problems of low production efficiency, poor fixing effect, and inconvenience of loading and unloading in the existing radiator production fixtures.

[0005] To achieve the above objectives, this utility model provides a fixture for radiator production, characterized in that it includes a fixture and a clamping device; the fixture has multiple fixed slots, and a movable slot and a limiting slot are provided between two fixed slots; the clamping device includes a connecting rod, a connecting block, a mating block, a movable plate, and an auxiliary block; the connecting rod connects multiple connecting blocks, one end of the connecting block is connected to the connecting rod, and the other end is connected to the mating block, and the connecting block provides support for the connecting rod; the mating block is I-shaped, the middle part is the same size as the limiting slot and can be placed in the limiting slot, and the lengths of both ends are the same as the length of the movable slot and can be placed in the movable slot; the movable plate has the same shape as the two ends of the mating block, and is connected to the mating block through the connecting rod, with multiple clamping plates at the end of the movable plate away from the mating block; the auxiliary block is fixedly located at the four corners of the connecting rod, its upper end is fixedly connected to the connecting rod, and its lower half is a slope, so that the bottom opening of the auxiliary block gradually narrows upwards.

[0006] Preferably, the fixing groove is vertically arranged and its depth is adapted to the height of the heat sink, and its width and length are consistent with the corresponding dimensions of the heat sink, so as to keep the heat sink stable during processing after it is placed in it.

[0007] Preferably, the movable slot and the fixed slot are adjacent to and connected to each other, the depth and length of the movable slot are less than the depth of the fixed slot, and the movable slot, the fixed slot and the radiator fins cooperate to form a pressure relief channel.

[0008] Preferably, the limiting groove is located between the two movable grooves, with the same depth as the movable grooves and a shorter length than the movable grooves.

[0009] Preferably, the mating block is provided with a limiting rod, a reserved hole, a spring, and an electromagnet; there are multiple limiting rods, which are fixedly disposed on both sides of the mating block, one end of which is fixedly connected to the mating block, and the other end is provided with a limiting block. The diameter of the limiting block is larger than the diameter of the limiting rod, and the length of the limiting rod is consistent with the width of the movable groove. It is used to limit the range of motion of the movable plate. When the clamping device needs to release the radiator, the end of the limiting rod with the limiting block contacts the radiator to limit the position of the radiator and prevent the radiator from moving with the movable plate.

[0010] Preferably, the reserved hole is located in the middle part of the mating block, one end of the spring is fixedly connected to the bottom of the reserved hole, and the other end is fixedly connected to the movable plate, which is used to apply a pulling force to the movable plate so that the movable plate contacts the mating block.

[0011] Preferably, the electromagnet is fixedly disposed on both sides of the mating block. When the electromagnet is energized and generates magnetic force, it generates a repulsive force on the movable plate, causing the movable plate to move away from the mating block.

[0012] Preferably, the movable plate is provided with a clamping plate, a flexible material layer and a magnet; the flexible material layer wraps around the clamping plate, and the magnet is arranged correspondingly to the electromagnet.

[0013] Preferably, the flexible material layer is fixed on the outer surface of the clamping plate and can be made of a relatively soft material such as sponge, silicone or brush. When the clamping plate is inserted into the gap between the heat sink fins, the flexible material layer is squeezed and deformed, so that the heat sink and the clamping plate are firmly connected, while avoiding deformation of the heat sink fins.

[0014] Preferably, the magnet is fixedly mounted on the movable plate and is arranged correspondingly to the electromagnet. The magnetic poles generated at the end of the magnet adjacent to the electromagnet are the same as the magnetic poles generated when the electromagnet is energized. Utilizing the principle of like poles repulsion, when the electromagnet is energized, it pushes the movable plate to move along the connecting rod, and at the same time, the spring is stretched.

The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the embodiments of the present invention, and should not be construed as limiting the present invention.

They are only for the convenience of describing the embodiments of this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0031] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of embodiments of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0032] In this embodiment of the invention, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this embodiment of the invention according to the specific circumstances.

[0033] In one embodiment of this utility model, such as Figure 1-4 As shown, a fixture for radiator production is provided, including a fixture 10 and a clamping device 20. The fixture 10 is provided with a plurality of fixing grooves 11. The fixing grooves 11 are designed to be vertical and deep. The depth of the fixing grooves 11 matches the height of the radiator, so that the radiator can be placed in the fixing grooves 11 and the fin bridge to be processed protrudes from the upper surface of the fixture 10. The width and length of the fixing grooves 11 are consistent with the width and length of the radiator, so that the radiator remains stable during the processing after being placed in the fixture 10, avoiding the problem of workpiece vibration caused by unstable fixing.

[0034] A movable groove 12 and a limiting groove 13 are provided between the two fixed grooves 11. The movable groove 12 is adjacent to and through the fixed grooves 11. The depth and length of the movable groove 12 are less than the depth of the fixed groove 11. The movable groove 12 serves to allow the clamping device 20 to be inserted and moved. Simultaneously, the movable groove 12, in conjunction with the radiator fins, creates pressure between the radiator and the fixture 10 when the radiator is placed in the fixed groove 11. Due to the high fit between the radiator and the fixture 10, the air between them will be compressed, creating pressure that, if not released promptly, will hinder the radiator's descent. At this time, the gap between the movable groove 12, the fixed groove 11, and the radiator fins forms a pressure relief channel, allowing for rapid air discharge and reducing resistance to radiator placement. It also reduces the negative pressure generated when the radiator is removed, facilitating its removal and placement.

[0035] The limiting groove 13 is disposed between the movable grooves 12, and the depth of the limiting groove 13 is the same as the depth of the movable groove 12. The length of the limiting groove 13 is less than the length of the movable groove 12. The limiting groove 13 cooperates with the movable groove 12 to position the clamping device 20, so that the clamping device 20 can accurately enter the limiting groove 13.

[0036] The clamping device 20 includes: a connecting rod 21, a connecting block 22, a mating block 23, a movable plate 24, and an auxiliary block 25. The connecting rod 21 connects multiple connecting blocks 22, so that lifting the connecting rod 21 can move the corresponding connecting block 22. The connecting block 22 connects the mating block 23 to the connecting rod 21. At the same time, the connecting block 22 supports the connecting rod 21 to prevent the connecting rod 21 from pressing against the top surface of the radiator when it moves above the radiator.

[0037] The mating block 23 is in the shape of an "I". The size of the middle part of the mating block 23 is the same as the size of the limiting groove 13 and is located in the limiting groove 13. The length of the two ends is the same as the length of the movable groove 12. The shape of the mating block 23 matches the movable groove 12 and the limiting groove 13, so that the mating block 23 can be accurately positioned in the movable groove 12 and the limiting groove 13.

[0038] The mating block 23 is equipped with a limiting rod 231, a reserved hole 232, a spring 233, and an electromagnet 234. Multiple limiting rods 231 are fixedly mounted on both sides of the mating block 23. One end of each limiting rod 231 is fixedly connected to the mating block 23, and the other end has a limiting block with a diameter larger than that of the limiting rod 231. The length of the limiting rod 231 is the same as the width of the movable groove 12. The limiting rod 231 restricts the range of motion of the movable plate 24. When the clamping device 20 needs to release the radiator, the end of the limiting rod 231 with the limiting block contacts the radiator, restricting the position of the radiator and preventing it from moving with the movable plate 24.

[0039] The reserved hole 232 is located in the middle part of the mating block 23. A spring 233 is provided in the reserved hole 232. One end of the spring 233 is fixedly connected to the bottom of the reserved hole 232, and the other end is fixedly connected to the movable plate 24. The spring 233 applies a pulling force to the movable plate 24, so that the movable plate 24 contacts the mating block 23.

[0040] The electromagnet 234 is fixedly disposed on both sides of the two ends of the mating block 23. The electromagnet 234 cooperates with the movable plate 24 so that when the electromagnet 234 is energized and generates magnetic force, it generates a repulsive force on the movable plate 24, causing the movable plate 24 to move away from the mating block 23.

[0041] The shape of the movable plate 24 is consistent with the shape of both ends of the mating block 23. The movable plate 24 is connected to the mating block 23 through the connecting rod 21. A plurality of clamping plates 241 are provided on the end of the movable plate 24 away from the mating block 23. The thickness of the clamping plate 241 is less than the gap between the radiator fins, and the length is less than the width of the radiator fins. The clamping plate 241 is inserted into the gap between the radiator fins under the action of the movable plate 24.

[0042] A flexible material layer 242 is fixedly provided on the periphery of the clamping plate 241. The flexible material layer 242 can be made of materials such as sponge, silicone, or brush. When the clamping plate 241 moves the flexible material layer 242 into the gap between the heat sink fins, the flexible material layer 242 is squeezed and deformed, thereby making the heat sink and the clamping plate 241 firmly connected, while preventing the heat sink fins from deforming.

[0043] The magnet 243 is fixed on the movable plate 24 and is correspondingly arranged with the electromagnet 234. The magnetic pole generated by the end of the magnet 243 adjacent to the electromagnet 234 is the same as the magnetic pole generated by the electromagnet 234 after it is energized. Like poles repel each other. The electromagnet 234 pushes the movable plate 24 to move along the connecting rod 21, while the spring 233 is stretched.

[0044] The auxiliary block 25 is fixedly installed at the four corners of the connecting rod 21. The upper end of the auxiliary block 25 is fixedly connected to the connecting rod 21, and the lower half is a slope, so that the opening at the bottom of the auxiliary block 25 gradually narrows upward. The auxiliary block 25 helps the connecting rod 21 to align with the clamp 10, so that the mating block 23 can be placed into the limiting groove 13 more smoothly.

[0045] The working principle of this utility model is as follows: A fixture for radiator production allows radiators to be placed one by one into a fixed slot 11. Alternatively, a turnover box with the same shape as the fixture can be used. By controlling the clamping device 20, multiple radiators can be clamped at once, allowing multiple radiators to be placed into the fixture 10 simultaneously. This enables the machine tool to process multiple radiators at the same time. Compared to existing fixtures that can only process one radiator at a time, this significantly shortens the processing cycle and greatly improves production efficiency. Furthermore, the design of the fixed slot ensures that the radiator is fully inserted and fits snugly, guaranteeing the stability of the radiator during processing and effectively preventing workpiece vibration caused by unstable fixing. After processing, the clamping device 20 moves above the fixture 10. Even if the connecting rod 21 is not fully aligned with the fixture 10, the inclined surface of the auxiliary block 25 provides guidance. Align the connecting rod 21 with the clamp 10. At this point, the movable plate 24 in the clamping device 20, under the tension of the spring 233, comes into contact with the mating block 23. The connecting rod 21 continues to approach the clamp 10, and the mating block 23 and the movable block 24 enter the movable groove 12 and the limiting groove 13. At this time, the electromagnet 234 is energized to generate magnetism, pushing the movable plate 24. The spring 233 is stretched, and the movable plate 24 drives the clamping plate 241 and the flexible material layer 242 into the gaps of the radiator fins, realizing the clamping operation of the clamping device 20 on the radiator. By moving the connecting rod 21, the radiator that has been processed in the clamp 10 is simultaneously removed, making the insertion and removal of the radiator more convenient. This design is also easy to integrate with automated equipment, realizing the automation of the radiator loading and unloading process, and has low requirements for the flexibility of automated equipment. It not only reduces the labor intensity of manual loading and unloading and reduces the damage that manual operation may cause to the radiator, but also can seamlessly connect with automated production lines to further improve production efficiency and reduce production costs.

[0046] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
