[0002] In existing copper component manufacturing processes, capillary flaring is typically done manually, which is not only inefficient but also makes it difficult to guarantee product quality. Manual operation easily leads to problems such as unstable flaring accuracy and poor dimensional consistency, failing to meet the process requirements of precision components. Although current automated flaring equipment on the market can complete some automated operations, its applicability is still limited when processing capillary tubes of different diameters and lengths, and it is difficult to maintain high precision while adapting to diverse needs.

[0003] Existing precision copper capillary flaring equipment has many limitations: it is difficult to adapt to capillary fittings of different sizes, requiring frequent fixture changes and having poor versatility; it is difficult to clamp multiple specifications of fittings simultaneously, and manual fixing is inefficient; the fittings are prone to shaking during flaring, resulting in insufficient positioning accuracy and unstable processing quality; the degree of automation is low, and manual intervention is required in each step, affecting work efficiency and consistency.

[0017] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0018] Example 1: This example provides an automatic flaring device for precision copper capillary tubes. See [link to example]. Figures 1 to 8 Specifically, the base plate 100 serves as the foundational load-bearing component of the equipment, providing an installation reference for components such as the fixed clamping plate 101, sliding mechanism, and fixed vertical plate 300, ensuring the relative stability of each component. Four fixed clamping plates 101 of increasing size are fixedly mounted on the top surface of the base plate 100 from left to right. Behind each fixed clamping plate 101 is a corresponding sliding clamping plate 112. The opposing surfaces of each fixed clamping plate 101 and sliding clamping plate 112... Each plate has a V-shaped notch. Capillary components 102 are placed between adjacent fixed clamping plates 101 and translation clamping plates 112. The capillary components 102 are the workpieces to be processed and are the objects of the entire flaring operation. The base plate 100 is connected to the four translation clamping plates 112 through a sliding mechanism. The V-shaped notches on the opposite surfaces of the fixed clamping plates 101 and the translation clamping plates 112 cooperate with each other to place and clamp the capillary components 102. The fixation of capillary components 102 of different sizes is completed through the relative movement of the two. A horizontally distributed fixed horizontal plate 301 is provided above the base plate 100. The fixed horizontal plate 301 provides a mounting carrier for components such as rectangular frame 201 and trapezoidal plate 200. Its lifting and lowering movement drives these components to lift and lower synchronously. A pair of rectangular sliding holes are provided at both ends of the fixed horizontal plate 301. A fixed vertical plate 300 is slidably inserted inside each rectangular sliding hole. The fixed vertical plate 300 provides a sliding guide for the fixed horizontal plate 301, restricts the movement direction of the fixed horizontal plate 301, and makes it lift and lower stably in the vertical direction. The bottom end of each fixed vertical plate 300 is fixedly connected to the base plate 100. A pair of rectangular frames 201 are fixedly sleeved on both sides of the fixed horizontal plate 301. The rectangular frames 201 transmit the movement of the fixed horizontal plate 301 to the trapezoidal plate 200. A trapezoidal plate 200 is fixedly installed at the front end of each rectangular frame 201. The trapezoidal plate 200 serves as a mounting carrier for components such as linkage mechanism and L-shaped stamping plate 210, and also provides fixing points for components such as rectangular ring 205 and L-shaped ear seat 204. A rectangular ring 205 is fixedly provided on the bottom side of the trapezoidal plate 200. The rectangular ring 205 provides a sliding guide for the L-shaped stamping plate 210, restricts the movement direction of the L-shaped stamping plate 210, and makes it slide stably in the vertical direction. The L-shaped stamping plate 210 is slidably inserted inside the rectangular ring 205. The L-shaped stamping plate 210 slides along the rectangular ring 205 under the drive of the linkage mechanism, driving the stamping head 211 to realize the flaring action on the capillary fitting 102. The L-shaped stamping plate 210 is connected to the trapezoidal plate 200 through the linkage mechanism. The bottom end of the L-shaped stamping plate 210 is fixedly provided with vertically distributed stamping heads 211. The stamping heads 211 move downward under the drive of the L-shaped stamping plate 210 to flare the top of the capillary fitting 102, and the bottom end of the stamping head 211 is slidably inserted into the top of the corresponding capillary fitting 102.

[0019] It should be noted that in this embodiment, each fixed vertical plate 300 is fixedly provided with a fixed ear 302 at its top end. The fixed ear 302 transmits the driving force of the third hydraulic cylinder 303 to the fixed horizontal plate 301, so that the fixed horizontal plate 301 can move up and down. A pair of rectangular through holes are opened on both sides of the fixed horizontal plate 301. A third hydraulic cylinder 303 with its telescopic end facing upward is fixedly installed inside each rectangular through hole. The end of the hydraulic rod of each third hydraulic cylinder 303 is fixedly connected to the fixed ear 302 on the same side. The extension and retraction of the hydraulic rod of the third hydraulic cylinder 303 drives the fixed horizontal plate 301 to move up and down along the fixed vertical plate 300 through the fixed ear 302, providing power for the lifting and lowering of the fixed horizontal plate 301 and related components.

[0020] The working principle of this embodiment is as follows: First, four capillary tubes 102 of different sizes are placed between the fixed clamping plate 101 and the translation clamping plate 112 in sequence. With the help of the sliding mechanism, the translation clamping plate 112 will move towards the fixed clamping plate 101. Through the relative movement of the fixed clamping plate 101 and the translation clamping plate 112, the capillary tubes 102 are stably clamped. Next, a pair of third hydraulic cylinders 303 are activated. Driven by them, the hydraulic rods of the third hydraulic cylinders 303 extend outward. Using the reaction force generated by the fixed lugs 302, the fixed horizontal plate 301 is moved downward along the pair of fixed vertical plates 300. The downward movement of the fixed horizontal plate 301 will simultaneously move the rectangular frame 201 and the trapezoidal plate 200 downward. Finally, with the cooperation of the linkage mechanism, the L-shaped stamping plate 210 will move accordingly, so that the stamping head 211 at its bottom end completes the automatic flaring operation on the top of the capillary tube 102.

[0021] Example 2: Based on Example 1, this example solves the problem of synchronous clamping and fixing of capillary tubes 102 of different sizes by adding a sliding mechanism with a specific structure, and also includes: In the specific implementation process, such as Figure 5 and Figure 6As shown, the sliding mechanism includes a T-shaped slide plate 104 and a U-shaped slide plate 109. A pair of symmetrically distributed first U-shaped rails 103 are fixed on the top surface of the base plate 100. The first U-shaped rails 103 provide a sliding track for the T-shaped slide plate 104, restricting the movement direction of the T-shaped slide plate 104 and ensuring its stable lateral sliding. A T-shaped slide plate 104 is slidably fitted inside each first U-shaped rail 103. The T-shaped slide plate 104 slides within the first U-shaped rail 103, driving the rectangular slide plate 105 and related components to move synchronously. A rectangular slide plate 105 is fixed on the top surface of each T-shaped slide plate 104, serving as the mounting carrier for the U-shaped slide plate 109. The U-shaped slide plate 109 is slidably engaged with the U-shaped slide plate 109 on both sides, providing support and guidance for the translation of the U-shaped slide plate 109. The U-shaped slide plate 109 slides on the rectangular slide plate 105, driving the L-shaped connecting plate 110 and the translation clamping plate 112 to translate, thereby realizing the clamping action of the capillary tube 102. The back of each translation clamping plate 112 is fixedly provided with an L-shaped connecting plate 110. The L-shaped connecting plate 110 transmits the movement of the U-shaped slide plate 109 to the translation clamping plate 112, so that the translation clamping plate 112 moves synchronously with the U-shaped slide plate 109. Each L-shaped connecting plate 110 is fixedly connected to the U-shaped slide plate 109 on the same side. A fixed connecting shaft 106 is inserted into the center of the top surface of the rectangular slide plate 105. The fixed connecting shaft 106 provides a mounting shaft for the fixed gear 107. At the same time, through the connection with the hinge connecting rod 108, the power of the hinge connecting rod 108 is transmitted to the rectangular slide plate 105. A fixed gear 107 is concentrically fixed in the center of the fixed connecting shaft 106. A pair of staggered rectangular racks 111 are meshed on both sides of the fixed gear 107. Each rectangular rack 111 is fixed to the U-shaped slide plate 109 on the same side. When the U-shaped slide plate 109 on one side stops moving, the fixed gear 107 rotates under the action of the rectangular rack 111, driving the rectangular rack 111 on the other side and the U-shaped slide plate 109 to move, realizing the sequential clamping action of the translation clamping plate 112 at different positions. A second U-shaped rail 113 is fixedly mounted on the top surface of the base plate 100. The second U-shaped rail 113 provides a sliding track for the I-shaped slider 114, ensuring that the I-shaped slider 114 slides stably in the lateral direction. The second U-shaped rail 113 is located between a pair of first U-shaped rails 103. The I-shaped slider 114 is slidably fitted inside the second U-shaped rail 113. The I-shaped slider 114 slides inside the second U-shaped rail 113, driving the central connecting shaft and the double-headed connecting rod 115 to move synchronously. A fixed bracket 116 is fixedly provided in the middle. The fixed bracket 116 provides a mounting point for the first hydraulic cylinder 117 to ensure the stable operation of the first hydraulic cylinder 117. The first hydraulic cylinder 117 with the telescopic end facing backward is fixedly installed inside the fixed bracket 116. The end of the hydraulic rod of the first hydraulic cylinder 117 is fixedly connected to the I-shaped slider 114. The first hydraulic cylinder 117 serves as the power source of the sliding mechanism. The extension and retraction of its hydraulic rod drives the I-shaped slider 114 to slide, providing driving force for the movement of the entire sliding mechanism. A central connecting shaft is inserted into the middle of the top surface of the I-shaped slider 114. A double-headed connecting rod 115 is fixed at the top of the central connecting shaft. The double-headed connecting rod 115 transmits the motion of the I-shaped slider 114 to the hinged connecting rod 108, realizing the power splitting and transmission. A pair of hinged connecting rods 108 are provided at both ends of the double-headed connecting rod 115. The hinged connecting rods 108 convert the motion of the double-headed connecting rod 115 into the rotation and translation of the fixed connecting shaft 106, thereby driving the rectangular slide plate 105 to move. The outer end of each hinged connecting rod 108 is movably hinged to the top end of the fixed connecting shaft 106 on the same side.

[0022] The working principle of this embodiment is as follows: Under the driving action of the first hydraulic cylinder 117, the hydraulic rod of the first hydraulic cylinder 117 is shortened, thereby driving the I-shaped slider 114, the central connecting shaft and the double-headed connecting rod 115 to slide forward along the second U-shaped rail 113. Under the hinge action of the double-headed connecting rod 115 and a pair of hinged connecting rods 108, the rectangular slide plate 105 and the T-shaped slide plate 104 are pushed forward along the first U-shaped rail 103 through the fixed connecting shaft 106, and at the same time, the U-shaped slide plate 109, the L-shaped connecting plate 110 and the translation clamping plate 112 are translated forward. As the rectangular slide plate 105 continues to move forward, when the translation clamp 112 on one side abuts against the corresponding capillary component 102, the U-shaped slide plate 109, L-shaped connecting plate 110, and translation clamp 112 on that side remain stationary. At this time, the rectangular rack 111 meshes with the fixed gear 107, driving the rectangular rack 111, U-shaped slide plate 109, L-shaped connecting plate 110, and translation clamp 112 on the other side to move forward and abut against the corresponding capillary component 102 on the other side. Under the combined action of the double-headed connecting rod 115 and a pair of hinged connecting rods 108, the four translational clamping plates 112, together with the four fixed clamping plates 101, eventually clamp and fix the four capillary tubes 102 of different sizes.

[0023] Example 3: Based on Example 2, this example solves the problem of precise positioning and stable clamping during the flaring of the capillary fitting 102 by adding a linkage mechanism with a specific structure and related components, thus achieving efficient flaring operations. It also includes: In the specific implementation process, such as Figure 7 and Figure 8 As shown, a fixed connecting plate 202 is fixedly provided on the top side of the trapezoidal plate 200. The fixed connecting plate 202 provides a sliding guide for the L-shaped slide plate 212 and provides a mounting point for the second hydraulic cylinder 213. A limit sliding hole is provided on the fixed connecting plate 202. The L-shaped slide plate 212 is slidably inserted inside the limit sliding hole. The L-shaped slide plate 212 drives these components to move synchronously under the drive of the second hydraulic cylinder 213. It is a key transmission component of the linkage mechanism. A limit through hole is provided on the fixed connecting plate 202. The second hydraulic cylinder 213 with the telescopic end facing down is fixedly installed inside the limit through hole. The end of the hydraulic rod of the second hydraulic cylinder 213 is fixedly connected to the bottom end of the L-shaped slide plate 212. The second hydraulic cylinder 213 serves as the power source of the linkage mechanism. The extension and retraction of its hydraulic rod drives the L-shaped slide plate 212 to slide, thereby driving the linkage mechanism and auxiliary clamping components to move. The linkage mechanism includes a transmission gear 215, a first rack 216, and a second rack 217. A pair of extended lugs 203 are fixedly provided on the middle of the side of the trapezoidal plate 200. The extended lugs 203 provide sliding support for the L-shaped stamping plate 210 and also provide a mounting point for the linkage shaft 214 to ensure the stable operation of the linkage mechanism. The top end of the L-shaped stamping plate 210 is slidably inserted between the pair of extended lugs 203, and a rotatably connected linkage shaft 214 is inserted between the outer ends of the pair of extended lugs 203. A concentrically fixed transmission gear 215 is sleeved in the middle of the linkage shaft 214. 15. The transmission gear 215 converts the linear motion of the second rack 217 into its own rotation, and then drives the first rack 216 to move through meshing, thereby realizing the transmission of power and the conversion of direction. The first rack 216 is fixed on the L-shaped stamping plate 210, and the second rack 217 is fixed on the L-shaped sliding plate 212. The transmission gear 215 is meshed with the first rack 216 and the second rack 217 respectively. Both are meshed with the transmission gear 215, and the motion is transmitted under the action of the transmission gear 215, so that the motion of the L-shaped stamping plate 210 and the L-shaped sliding plate 212 are related to each other. A pair of symmetrically distributed L-shaped lugs 204 are fixed on both sides of the trapezoidal plate 200. Each L-shaped lug 204 has a movable hinged single lug 208 at its outer end. The L-shaped lugs 204 and the single lugs 208 provide fulcrums for the hinged swing of the fixed connecting rod 206, limiting its movement trajectory. Each single lug 208 has a vertically distributed fixed connecting rod 206 fixed at its outer end. Each fixed connecting rod 206 has a V-shaped lug fixed at its bottom end. A pair of V-shaped clamps 207 are placed against the top of the outer surface of the corresponding capillary fitting 102. The fixed connecting rod 206 and the V-shaped clamps 207 are hinged and swung along the L-shaped lug 204 under the drive of the driven connecting rod 209, causing the V-shaped clamps 207 to abut against the top of the outer surface of the capillary fitting 102. Together with the fixed clamp 101 and the translation clamp 112, the capillary fitting 102 is stably clamped to prevent it from shaking when it is flared. The top of the L-shaped slide 212 is fixedly inserted with a through-type limiting shaft 218. The two ends of the limiting shaft 218 are hinged with a pair of staggered driven links 209. The top of each driven link 209 is movably hinged to the top of the fixed link 206 on the same side. The limiting shaft 218 transmits the movement of the L-shaped slide 212 to the driven link 209. The driven link 209 drives the fixed link 206 to swing, realizing the clamping action of the V-shaped clamp 207.

[0024] The working principle of this embodiment is as follows: Under the driving action of the second hydraulic cylinder 213, the hydraulic rod of the second hydraulic cylinder 213 is shortened, which drives the L-shaped slide plate 212 and the second rack 217 to slide upward along the limiting slide hole. Since the transmission gear 215 is meshed with the first rack 216 and the second rack 217 respectively, the second rack 217 will mesh to drive the transmission gear 215 and the linkage shaft 214 to rotate. Then, the transmission gear 215 meshes to drive the first rack 216 and the L-shaped stamping plate 210 to slide downward along the rectangular ring 205 and a pair of extended ear seats 203, and simultaneously drive the stamping head 211 to be inserted downward into the top of the corresponding capillary component 102. At the same time, the top of the L-shaped slide plate 212 drives a pair of driven connecting rods 209 to rise upward through the limiting connecting shaft 218. Under the hinge action of the driven connecting rod 209 and the fixed connecting rod 206, the fixed connecting rod 206 and the single ear seat 208 are driven to swing inward along the L-shaped ear seat 204, so that a pair of V-shaped clamping plates 207 abut against the top of the corresponding capillary component 102. Together with the fixed clamping plate 101 and the translation clamping plate 112, the capillary component 102 is clamped more firmly. Then, under the action of the stamping head 211, the automatic flaring operation of the capillary component 102 is completed.

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
