Description

Technical Field

[0001] This utility model relates to the field of copper tube processing technology, and more specifically, to a copper tube hot-melt drilling device. Background Technology

[0002] The hot melt process is a chipless machining technique that creates holes and bushings in a single pass on a thin metal sheet or tube. Hot melt drills are made of wear-resistant and high-temperature resistant cemented carbide materials. When the tool comes into contact with the workpiece, the high rotation speed and appropriate axial thrust cause intense friction between the drill bit and the metal, instantly reaching a temperature of 650°C to 750°C. The drill bit area softens rapidly, and with continued application of axial pressure, the hot melt drill quickly penetrates the part.

[0003] When drilling copper tubes, unstable clamping during rapid penetration by a thermoforming drill can cause the copper tube to shift or tilt during the drilling process, resulting in a deviation from the predetermined drilling position, uneven hole diameter, and uneven support, which can lead to deviations in the drilling angle and cause the drilling direction to deviate from the predetermined vertical or horizontal direction, affecting the drilling quality. At the same time, existing copper tube clamping devices are not convenient for rotating and adjusting the direction of the copper tube after the clamping is stable, which reduces drilling efficiency and convenience. Utility Model Content

[0004] In view of the problems existing in the prior art, this utility model provides a copper tube hot-melt drilling device to solve the technical problem of unstable copper tube clamping mentioned in the background art.

[0005] Technical solution

[0006] To achieve the above objectives, this utility model provides the following technical solution: a copper tube hot-melt drilling device, comprising a drilling machine, the drilling machine including a worktable and a hot-melt drilling machine, a moving machine on the worktable, a clamping device and a supporting device on the moving machine, the clamping device including a clamping seat, a rotating shaft on the clamping seat via a bearing, a rotating seat on the rotating shaft, a clamping box and a clamping housing on the rotating seat, a clamping sleeve circumferentially slidably disposed on the clamping box, a clamping screw rotatably disposed on the clamping housing, the clamping screw being threadedly connected to the clamping sleeve, a clamping plate disposed on the clamping sleeve, and the supporting device including a supporting base and a supporting seat, a supporting groove disposed within the supporting base, a supporting rod slidably disposed on the supporting base, a supporting block disposed at the bottom of the supporting rod, and an adjusting block cooperating with the supporting block slidably disposed within the supporting groove.

[0007] The present invention is further configured such that the clamping screw is provided with a first bevel gear in the clamping box, a clamping motor is provided on one side of the clamping box, and a second bevel gear that cooperates with the first bevel gear is rotatably provided on the motor shaft of the clamping motor. The clamping motor drives the second bevel gear to rotate, thereby driving the first bevel gear and the clamping screw to rotate.

[0008] The present invention is further configured such that a clamping screw is provided on the rotating seat, and a clamping head is provided at one end of the clamping screw, which facilitates clamping and fixing the outer wall of the copper tube.

[0009] The present invention is further provided with a rotating handle fixedly provided at one end of the rotating shaft, so as to facilitate the rotation of the rotating shaft.

[0010] The present invention is further configured such that a rotating ring is fixedly provided on the rotating shaft, a limiting sleeve is provided on the clamping seat, a limiting rod is slidably provided on the limiting sleeve, and a limiting hole is provided on the rotating ring to cooperate with the limiting rod. The positions of the rotating ring and the rotating shaft are fixed by the cooperation of the limiting rod and the limiting hole.

[0011] The present invention is further configured such that the limiting rod is provided with a limiting plate inside the limiting sleeve, and a limiting spring is provided between the limiting sleeve and the limiting plate, so that the limiting rod has a continuous and stable elastic force pointing towards the limiting hole.

[0012] The present invention is further configured such that a rotating roller is provided circumferentially on the support base, thereby reducing the frictional force of the copper tube rotating on the support base.

[0013] The present invention is further configured such that an adjusting screw is rotatably provided on the support base, one end of the adjusting screw is rotatably connected to the adjusting block, and the other end is fixedly provided with an adjusting knob, so as to facilitate moving the position of the adjusting block. Beneficial effects

[0014] Compared with the prior art, this utility model provides a copper tube hot-melt drilling device, which has the following beneficial effects:

[0015] 1. The clamping motor drives the second bevel gear to rotate, which in turn drives the first bevel gear and the clamping screw to rotate, thereby driving the clamping sleeve and clamping plate to support the copper tube outward. The copper tube is internally supported by the clamping screw and clamping head, which externally clamps the copper tube. This makes it easy to fix copper tubes of different diameters on the clamping seat. At the same time, the position of the copper tube is adjusted by the moving machine, and drilling is performed by the hot melt drill, which improves the convenience of processing.

[0016] 2. The rotating shaft is driven to rotate by turning the handle, which in turn drives the rotating ring and the rotating seat to rotate, which in turn drives the copper tube to rotate, thus improving the ease of processing. Then, the rotation direction of the rotating shaft and the rotating ring is fixed by the cooperation of the limiting rod and the limiting hole to prevent the copper tube from rotating during drilling.

[0017] 3. The adjustment knob drives the adjustment screw to rotate, which in turn moves the adjustment block. The adjustment block, in conjunction with the support block, moves the support block and support rod, thereby adjusting the vertical height of the support base. This facilitates the support of copper tubes of different diameters, improving adaptability. The addition of a rotating roller reduces the friction of the copper tube rotating on the support base.

[0027] Please see Figures 1-5 A copper pipe hot-melt drilling device includes a drilling machine 1, which includes a worktable 2 and a hot-melt drilling machine 3. A moving machine 4 is mounted on the worktable 2, and a clamping device and a supporting device are mounted on the moving machine 4. The clamping device includes a clamping seat 5, a rotating shaft 6 mounted on the clamping seat 5 via a bearing, a rotating seat 7 mounted on the rotating shaft 6, a clamping box 8 and a clamping sleeve 9 mounted on the rotating seat 7, a clamping sleeve 10 slidably mounted on the clamping box 8, and a clamping screw 11 rotatably mounted on the clamping sleeve 9. The clamping screw 11 is threadedly connected to the clamping sleeve 10, and a clamping plate 12 is mounted on the clamping sleeve 10. The supporting device includes a supporting base 13 and a supporting seat 14, with a supporting groove 15 inside the supporting base 13. A support rod 16 is slidably mounted on the support 15, and a support block 17 is mounted at the bottom of the support rod 16. An adjusting block 18 that cooperates with the support block 17 is slidably mounted in the support groove 15. A clamping screw 11 is provided with a first bevel gear 19 in the clamping box 9. A clamping motor 20 is provided on one side of the clamping box 8. A second bevel gear 21 that cooperates with the first bevel gear 19 is rotatably mounted on the motor shaft of the clamping motor 20. A pressing screw 22 is provided on the rotating seat 7. A pressing head 23 is provided at one end of the pressing screw 22. A rotating roller 31 is provided around the support seat 14. An adjusting screw 32 is rotatably mounted on the support base 13. One end of the adjusting screw 32 is rotatably connected to the adjusting block 18, and the other end is fixedly provided with an adjusting knob 33.

[0028] In this embodiment, when processing the copper tube, one end of the copper tube is placed against the clamping seat 5, and the clamping motor 20 is started. The clamping motor 20 drives the second bevel gear 21 to rotate, which in turn drives the first bevel gear 19 and the clamping screw 11 to rotate. The clamping screw 11 rotates threadedly with the clamping sleeve 10, causing the clamping sleeve 10 and the clamping plate 12 to support outward. Then, the clamping screw 22 is rotated, which drives the clamping head 23 to move towards the copper tube. The clamping head 23 clamps and presses the outside of the copper tube to fix its position. The other end of the copper tube is supported on the support seat 14. The adjustment knob 33 is rotated. The adjusting knob 33 drives the adjusting screw 32 to rotate, and the adjusting screw 32 drives the adjusting block 18 to move within the support groove 15. The adjusting block 18 obliquely supports the support block 17, causing the support block 17, support rod 16, and support seat 14 to move upward. The position of the support seat 14 is adjusted to ensure the copper tube is horizontal, preventing the copper tube from tilting and affecting the drilling accuracy. The position of the copper tube is moved by the moving machine 4. The moving machine 4 uses a motor to drive the screw to rotate, and the screw drives the moving block to move, which facilitates the movement of the copper tube. The copper tube is drilled by the hot melt drill 3. Both the hot melt drill 3 and the moving machine 4 are existing technologies, and their principles will not be elaborated here.

[0029] Please see Figures 4-5 As one embodiment of the rotating shaft 6: a rotating handle 24 is fixedly provided at one end of the rotating shaft 6, a rotating ring 25 is fixedly provided on the rotating shaft 6, a limiting sleeve 26 is provided on the clamping seat 5, a limiting rod 27 is slidably provided on the limiting sleeve 26, a limiting hole 28 is provided on the rotating ring 25 to cooperate with the limiting rod 27, a limiting plate 29 is provided inside the limiting sleeve 26 for the limiting rod 27, and a limiting spring 30 is provided between the limiting sleeve 26 and the limiting plate 29.

[0030] More specifically, when the copper tube is rotated, the limiting rod 27 is pulled outward, and the limiting rod 27 drives the limiting plate 29 to compress the limiting spring 30. The limiting rod 27 leaves the limiting hole 28, and the rotating handle 24 is rotated. The rotating handle 24 drives the rotating shaft 6, the rotating ring 25 and the rotating seat 7 to rotate. The rotating seat 7 drives the copper tube to rotate. After the rotation is completed, the limiting rod 27 is released. Under the elastic force of the limiting spring 30, the limiting plate 29 drives the limiting rod 27 to insert into the limiting hole 28, thereby fixing the position of the rotating ring 25 and the rotating seat 7. When the clamping seat 5 drives the copper tube to rotate, the copper tube rotates on the support seat 14. The rotating roller 31 reduces the friction of the copper tube rotation.

[0031] In summary, during the use or operation of the overall equipment: when processing copper tubes, one end of the copper tube is placed against the clamping seat 5, and the clamping motor 20 is started. The clamping motor 20 drives the second bevel gear 21 to rotate, which in turn drives the first bevel gear 19 and the clamping screw 11 to rotate. The clamping screw 11 and the clamping sleeve 10 rotate threadedly, causing the clamping sleeve 10 and the clamping plate 12 to support outwards. Then, the clamping screw 22 is rotated, which drives the clamping head 23 to move towards the copper tube. The clamping head 23 clamps and presses the copper tube to fix its position. The other end of the copper tube is supported on the support seat 14. The adjustment is then made by rotating the screw. Knob 33, when adjusted, drives the adjusting screw 32 to rotate. The adjusting screw 32 then moves the adjusting block 18 within the support groove 15. The adjusting block 18 obliquely supports the support block 17, causing the support block 17, support rod 16, and support base 14 to move upwards. The position of the support base 14 is adjusted to ensure the copper tube is horizontal, preventing the copper tube from tilting and affecting the drilling accuracy. The position of the copper tube is moved by the moving machine 4. The moving machine 4 uses a motor to drive the screw to rotate, and the screw drives the moving block to move, which facilitates the movement of the copper tube. The copper tube is then drilled by the hot melt drill 3. Both the hot melt drill 3 and the moving machine 4 are existing technologies, and their principles will not be elaborated further.

[0032] When the copper tube is rotated, the limiting rod 27 is pulled outward. The limiting rod 27 drives the limiting plate 29 to compress the limiting spring 30. The limiting rod 27 leaves the limiting hole 28. The rotating handle 24 is rotated, which drives the rotating shaft 6, rotating ring 25 and rotating seat 7 to rotate. The rotating seat 7 drives the copper tube to rotate. After the rotation is completed, the limiting rod 27 is released. Under the elastic force of the limiting spring 30, the limiting plate 29 drives the limiting rod 27 to insert into the limiting hole 28, thereby fixing the position of the rotating ring 25 and the rotating seat 7. When the clamping seat 5 drives the copper tube to rotate, the copper tube rotates on the support seat 14. The rotating roller 31 reduces the friction of the copper tube rotation.
