Description

Technical Field

[0001] This utility model relates to the field of industrial cutting technology, specifically a capillary copper tube fixed-length cutting device. Background Technology

[0002] Capillary copper tubes are copper and copper alloy capillary tubes, generally 1 to 6 meters in length, with an outer diameter of 0.5 mm to 3 mm and an inner diameter of 0.3 mm to 2.5 mm. They are made of copper, brass, and other special copper tubes. Capillary copper tubes are generally used in small Freon refrigeration units below 10 kW. The capillary tubes are made of pure copper, and the length requirements of capillary copper tubes vary depending on the application environment.

[0003] A search revealed a patent with publication number CN211589295U, which discloses a rapid capillary copper tube cutting device. The device includes a base plate, a motor fixedly connected to the upper surface of the base plate, and a mounting box fixedly connected to the upper surface of the base plate. A cutting device is fixedly connected to the inner bottom wall of the mounting box. A rotating shaft is fixedly connected to the output end of the motor, and the right end of the rotating shaft extends through and into the interior of the mounting box. This rapid capillary copper tube cutting device uses U-shaped slots. The capillary copper tube to be cut is placed into the U-shaped slots. When a person rotates a handle, the connecting rod drives the threaded rods to rotate. Because the threads of the two threaded rods are in opposite directions, the rotation of the threaded rods causes the two threaded sleeves to move relative to each other or in opposite directions. Simultaneously, the two U-shaped slots slide relative to each other or in opposite directions within a slide rail via sliders. This design achieves a clamping effect for copper tubes of different lengths.

[0004] The aforementioned prior art cannot perform fixed-length cutting of capillary copper tubes. Operators need to manually measure and mark the cutting position of the capillary copper tube before each cutting, and then fix and cut it. This series of operations is not only cumbersome, but also prone to inconsistent lengths of capillary copper tubes due to human measurement errors, affecting product quality. Utility Model Content

[0005] The purpose of this section is to outline some aspects of the embodiments of this utility model and to briefly introduce some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be used to limit the scope of this utility model.

[0006] In view of the problems existing in the above and / or existing capillary copper tube length cutting devices, this utility model is proposed.

[0007] To solve the above-mentioned technical problems, according to one aspect of the present invention, the present invention provides the following technical solution: A capillary copper tube fixed-length cutting device includes a frame, a fixed-length cutting component slidably mounted on the frame, a drive cylinder provided on the frame, and the drive rod of the drive cylinder connected to the fixed-length cutting component. A limit mechanism is provided on one side of the frame.

[0008] As a preferred embodiment of the capillary copper tube fixed-length cutting device of this utility model, the fixed-length cutting assembly includes a movable frame slidably mounted on a frame, a positioning column is provided on the movable frame, a rotating sleeve is rotatably mounted on the outer wall of the positioning column, a plurality of arc-shaped holes are symmetrically opened on the rotating sleeve, and a slider is slidably mounted in the arc-shaped holes. A movable frame is provided on the slider, and the movable frame is slidably mounted on the positioning column. A cutting mechanism is provided on the outer wall of the slider.

[0009] As a preferred embodiment of the capillary copper tube fixed-length cutting device of this utility model, a second gear is provided on one side of the rotating sleeve, a first gear is inserted and rotatably installed on one side of the movable frame, and the first gear and the second gear mesh with each other. A motor is provided on one side of the frame, and the output end of the motor is connected to the first gear.

[0010] As a preferred embodiment of the capillary copper tube fixed-length cutting device of the present invention, the limiting mechanism includes a first support frame symmetrically arranged, and a plurality of sleeves are provided on the outer wall of the first support frame.

[0011] As a preferred embodiment of the capillary copper tube fixed-length cutting device of this utility model, several of the sleeves are distributed in an arc shape on one side of the first support frame.

[0012] As a preferred embodiment of the capillary copper tube fixed-length cutting device of the present invention, a second support frame is slidably installed on one side of the cutting mechanism, and the second support frame is slidably installed on the outer wall of the frame. The second support frame includes an arc-shaped plate disposed on one side of the cutting mechanism, and a plurality of clamps are disposed on the outer wall of the arc-shaped plate.

[0013] As a preferred embodiment of the capillary copper tube fixed-length cutting device described in this utility model, a guide plate is provided on the frame.

[0014] Compared with the prior art, the beneficial effects of this utility model are: In this solution, the motor drives the rotating sleeve to rotate through gear transmission. The arc-shaped hole on the rotating sleeve pushes the slider to slide radially along the positioning column, thereby adjusting the distance between multiple cutting mechanisms to achieve the adjustment of different fixed-length cutting dimensions. The drive cylinder drives the fixed-length cutting assembly to move up and down, so that the cutting mechanism cuts the capillary copper tube that passes through the sleeve of the limiting mechanism. By preset the distance between the cutting mechanisms, the fixed-length cutting of the capillary copper tube is achieved, eliminating the need for manual measurement and marking, and improving the convenience and accuracy of cutting. In this design, when adjusting the spacing of the cutting mechanism, the second support frame moves synchronously with the cutting mechanism and is always located adjacent to the cutting point. The capillary copper tube passes through the sleeve of the limiting mechanism and the clamp of the second support frame, and the clamp holds and supports the copper tube. During cutting, the cutting mechanism moves downward and the second support frame moves synchronously. The clamp always supports the capillary copper tube near the cutting point, preventing the copper tube from bending or vibrating and ensuring the stability of the cutting.

Detailed Implementation

[0017] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0018] Secondly, this utility model is described in detail with reference to the schematic diagrams. When describing the embodiments of this utility model, for ease of explanation, the cross-sectional views showing the device structure may be partially enlarged, not according to the usual scale. Furthermore, the schematic diagrams are merely examples and should not limit the scope of protection of this utility model. In addition, in actual manufacturing, the three-dimensional spatial dimensions of length, width, and depth should be included.

[0019] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0020] Example 1 Please see Figures 1-4 This utility model provides a technical solution: A capillary copper tube fixed-length cutting device is provided, which can realize fixed-length cutting of capillary copper tubes and the cutting length can be adjusted. It eliminates the need for manual measurement and marking, improves cutting efficiency and accuracy, and ensures product quality consistency.

[0021] The capillary copper tube length-cutting device includes a frame 1, which is a metal frame structure serving as the supporting foundation for the entire device. A length-cutting assembly 2 is slidably mounted on the frame 1 for performing length-cutting operations on the capillary copper tube. A drive cylinder 5, a hydraulic cylinder, is fixedly mounted on the frame 1; its drive rod is fixedly connected to the length-cutting assembly 2, driving the assembly 2 to move up and down. A limit mechanism 3 is provided on one side of the frame 1 to constrain the position of the capillary copper tube, ensuring stability during cutting. Component 2 includes a movable frame 6 slidably mounted on the frame 1. The movable frame 6 can slide along the vertical direction of the frame 1. A positioning post 7 is fixed on the movable frame 6. The positioning post 7 is a cylindrical metal post, and a rotating sleeve 8 is rotatably mounted on its outer wall via bearings. The rotating sleeve 8 can rotate around the axis of the positioning post 7. Several arc-shaped holes 12 are symmetrically opened on the rotating sleeve 8. The arc-shaped holes 12 are radially distributed with the axis of the rotating sleeve 8 as the center. A slider 13 is slidably mounted in the arc-shaped holes 12. The slider 13 can slide along the arc-shaped holes 12. A movable frame 16 is fixed on the slider 13. The movable frame 16 is slidably mounted on the positioning post 7 and can slide radially along the positioning post 7. The movable frame 16 guides the sliding of the slider 13.

[0022] A cutting mechanism 14 is provided on the outer wall of the slider 13. The cutting mechanism 14 is a small disc electric saw used to cut capillary copper tubes. A second gear 11 is fixed on one side of the rotating sleeve 8. A first gear 10 is inserted into one side of the movable frame 6 and rotated through a bearing. The first gear 10 meshes with the second gear 11. A motor 9 is fixed on one side of the frame 1. The output end of the motor 9 is connected to the first gear 10 through a coupling. The motor 9 can drive the first gear 10 to rotate. The limiting mechanism 3 includes a symmetrically arranged first support frame 15. The first support frame 15 is a metal bracket. Several sleeves are fixed on its outer wall. The sleeves are distributed in an arc shape on one side of the first support frame 15. The inner diameter of the sleeves is adapted to the outer diameter of the capillary copper tube and is used to pass through and constrain the capillary copper tube.

[0023] Motor 9 drives rotating sleeve 8 to rotate via gear transmission. The arc-shaped hole 12 on rotating sleeve 8 pushes slider 13 to slide radially along positioning post 7, thereby adjusting the distance between multiple cutting mechanisms 14 to achieve adjustment of different fixed-length cutting dimensions. Drive cylinder 5 drives fixed-length cutting assembly 2 to move up and down, so that cutting mechanism 14 cuts capillary copper tubes that pass through the sleeve of limiting mechanism 3. The sleeve of limiting mechanism 3 constrains the position of capillary copper tubes to ensure accurate cutting position. By preset the distance between cutting mechanisms 14, fixed-length cutting of capillary copper tubes is achieved without manual measurement and marking.

[0024] In use, according to the required length of the capillary copper tube, start motor 9. Motor 9 drives the first gear 10 to rotate. The first gear 10 drives the meshing second gear 11 to rotate. The second gear 11 drives the rotating sleeve 8 to rotate around the positioning post 7. When the rotating sleeve 8 rotates, the arc-shaped hole 12 rotates with it. The slider 13 slides radially along the positioning post 7 under the action of the arc-shaped hole 12. The movable frame 16 slides synchronously, thereby adjusting the distance between the cutting mechanisms 14 to be equal to the required cutting length. After the adjustment is completed, turn off motor 9 and pass the capillary copper tube through the sleeve of the limiting mechanism 3 so that one end of the copper tube extends to the cutting position of the cutting mechanism 14. The sleeve constrains the copper tube to prevent it from shaking during cutting. Start drive cylinder 5. Drive cylinder 5 drives movable frame 6 to move the fixed-length cutting assembly 2 downward. The cutting mechanism 14 contacts the capillary copper tube and cuts it. After the cutting is completed, drive cylinder 5 drives the fixed-length cutting assembly 2 to reset upward. Take out the cut capillary copper tube, and then push the remaining capillary copper tube forward so that it extends to the cutting position again. Repeat the above cutting process.

[0025] Example 2 Please see Figures 1-4 This utility model provides a technical solution: Based on Example 1, a support structure was added to further improve the stability of the capillary copper tube during cutting and ensure the quality of the cut. It is especially suitable for cutting thinner or longer capillary copper tubes.

[0026] A second support frame 17 is slidably mounted on one side of the cutting mechanism 14 and is slidably mounted on the outer wall of the frame 1. In this way, the second support frame 17 can move up and down laterally under the drive of the cutting mechanism 14, and the second support plate 17 can also move laterally on the frame 1. At the same time, the second support plate 17 can also slide up and down relative to the cutting mechanism 14. This can prevent the second support plate 17 from moving when the cutting mechanism 14 cuts the capillary copper tube. The second support frame 17 includes an arc-shaped plate 18 set on one side of the cutting mechanism 14. The arc of the arc-shaped plate 18 is adapted to the shape of the capillary copper tube. Several clamps 19 are set on the outer wall of the arc-shaped plate 18. The clamps 19 are elastic clamps that can clamp the capillary copper tube and support it. A guide plate 4 is fixed on the frame 1. The guide plate 4 is a smooth metal plate used to guide the pushing of the capillary copper tube.

[0027] When adjusting the spacing of the cutting mechanism 14, the second support frame 17 moves synchronously with the cutting mechanism 14 and is always located adjacent to the cutting point. The capillary copper tube passes through the sleeve of the limiting mechanism 3 and the clamp 19 of the second support frame 17. The clamp 19 clamps and supports the copper tube. During cutting, the cutting mechanism 14 moves downward and the second support frame 17 moves synchronously. The clamp 19 always supports the capillary copper tube near the cutting point to prevent the copper tube from bending or vibrating.

[0028] Unlike Embodiment 1, the second support frame 17 added in this embodiment moves synchronously with the cutting mechanism 14 to support and clamp the capillary copper tube near the cutting point, further improving the stability during cutting. Especially for thin and long capillary copper tubes, it can effectively prevent them from bending or vibrating due to force during cutting, ensuring a smooth cut.

[0029] Although the present invention has been described above with reference to embodiments, various modifications can be made and components can be replaced with equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the features in the embodiments disclosed in this invention can be combined with each other in any way. The lack of an exhaustive description of these combinations in this specification is merely for the sake of brevity and resource conservation. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
