Description

Technical Field

[0001] This utility model relates to the field of copper tube processing technology, specifically to an auxiliary tooling for copper tube cutting. Background Technology

[0002] Copper pipe cutting auxiliary fixtures are tools or devices specifically designed to assist in the cutting of copper pipes. Copper pipe cutting auxiliary fixtures typically have clamping or supporting structures that can securely fix the copper pipe and prevent it from moving during the cutting process.

[0003] When handling copper tube cutting tasks of different diameters, a cylinder-driven V-shaped clamp is relied upon to adapt to various copper tube sizes. However, in actual operation, the vibration generated during the operation of the cutting equipment can easily damage the cylinder, which in turn causes the telescopic end to lock up. This makes it difficult to quickly remove the cut copper tube from the V-shaped clamp, affecting the efficiency of subsequent processing. In addition, given the soft nature of copper, if forced removal is used, scratches or indentations are easily left on the surface of the copper tube, damaging its appearance quality and integrity. Therefore, an auxiliary tooling for copper tube cutting is proposed to address the above problems. Utility Model Content

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this application. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.

[0023] Please see Figure 1-5 This utility model provides a technical solution:

[0024] A copper pipe cutting auxiliary fixture includes a workbench 1. An anti-locking component 2 is bolted to the upper surface of the workbench 1. A guide roller conveyor 3 is fixedly connected to the middle of the workbench 1. The anti-locking component 2 includes a fixed base 21. A rubber pad 22 is fixedly connected to the bottom end of the fixed base 21, providing good cushioning and reducing the impact of vibration on the electric cylinder 23. An electric cylinder 23 is fixedly connected to the middle of one side of the fixed base 21. A push plate 24 is fixedly connected to the telescopic end of the electric cylinder 23. Positioning rods 25 are fixedly connected to both sides of the push plate 24. A pressure sensor 26 is fixedly connected to the middle of the push plate 24. Movable plates 27 are elastically connected to one side of the two push plates 24 via buffer springs 271. A clamping mechanism 28 is fixedly connected to the middle of the movable plate 27. The clamping mechanism 28 includes a fixed block 280. An adjusting rail 281 is fixedly connected to one end of the fixed block 280. An internal double-acting lead screw 282 is rotatably connected via a lead screw seat. Adjusting seats 283 are threaded onto both sides of the double-acting lead screw 282. Clamping blocks 284 are fixedly connected to the outer side of the adjusting seats 283. The cross-section of the clamping blocks 284 is a right-angled trapezoid. The top clamping block 284 and the bottom clamping block 284 are symmetrically arranged vertically. A fixing plate 285 is fixedly connected to the surface of the clamping blocks 284. A connecting seat 286 is fixedly connected to the middle of the fixing plate 285. A clamping seat 287 is rotatably connected to the inner side of the connecting seat 286. Rubber wheels 288 are rotatably connected to both sides of the clamping seat 287. Return springs 289 are fixedly connected to both sides of the rear end face of the clamping seat 287. The return springs 289 are fixedly connected to the fixing plate 285. The elastic force generated between the return springs 289 and the rubber wheels 288 provides good cushioning when in contact with the copper tube surface, and also facilitates the reset of the clamping seat 287.

[0025] As a further implementation of this solution, several anti-locking components 2 are provided, and several anti-locking components 2 are symmetrically arranged on both sides of the workbench 1. A guide column 210 is fixedly connected to one side of the fixed base 21. The guide column 210 and the movable plate 27 are slidably engaged. The bottom end of the guide column 210 is in contact with the upper surface of the rubber pad 22, thus providing support for the bottom end of the movable plate 27.

[0026] As a further implementation of this solution, the cross-section of the fixed base 21 is set to "L" shape. The bottom of the fixed base 21 is fixedly connected to the PLC controller 211. The pressure sensor 26 is electrically connected to the power supply through the PLC controller 211. Once the pressure reaches the preset threshold, the PLC controller 211 immediately intervenes and instructs the electric cylinder 23 to stop applying pressure, thereby ensuring precise control of the clamping force.

[0027] As a further implementation of this solution, the positioning rod 25 passes through the interior of the push plate 24. One end of the positioning rod 25 is slidably connected to the fixed base 21, and the other end of the positioning rod 25 is slidably connected to the movable plate 27. This arrangement improves the stability of horizontal movement.

[0028] As a further implementation of this solution, the buffer spring 271 is sleeved on one side of the positioning rod 25. One end of the buffer spring 271 is fixedly connected to the front end face of the push plate 24, and the other end of the buffer spring 271 is fixedly connected to the rear end face of the movable plate 27. This arrangement has a better buffer protection effect.

[0029] As a further implementation of this scheme, an adjusting wheel 2821 is rotatably connected to the top of the adjusting rail 281. The bottom end of the adjusting wheel 2821 penetrates into the interior of the adjusting rail 281 and is fixedly connected to the top end of the bidirectional lead screw 282. This arrangement facilitates the rotation of the bidirectional lead screw 282.

[0030] Workflow: The copper tube to be processed is placed horizontally on the surface of the guide roller conveyor 3. By activating the electric cylinder 23, the telescopic end of the electric cylinder 23 pushes the push plate 24 forward. During this movement, the positioning rod 25 slides against the fixed seat 21 to ensure stability. The push plate 24 pushes the movable plate 27 forward along the path of the positioning rod 25. Simultaneously, the positioning rod 25 moves, causing the clamping mechanism 28 to move forward. The clamping seat 287 and rubber wheel 288 of the clamping mechanism 28 contact the outer side of the copper tube, achieving clamping and limiting of the copper tube. During this process, the elastic force generated between the return spring 289 and the rubber wheel 288 provides good cushioning when in contact with the copper tube surface, while also facilitating the reset of the clamping seat 287. The rubber wheel 288, made of rubber, protects the copper tube from scratches. When the electric cylinder 23 applies pressure, the movable plate... The movable plate 27 moves in the opposite direction due to the resistance of the clamping mechanism 28. The pressure sensor 26 detects the pressure value in contact with the movable plate 27 in real time. Once the pressure reaches the preset threshold, the PLC controller 211 intervenes immediately and instructs the electric cylinder 23 to stop applying pressure. During this process, the buffer spring 271 provides good buffer protection for the pressure applied by the electric cylinder 23. When the electric cylinder 23 malfunctions, the clamping mechanism 28 can be adjusted left and right within a certain range. When the electric cylinder 23 malfunctions while the copper tube is being clamped, since the movable plate 27 and the push plate 24 are in complete contact, the bidirectional screw 282 can be rotated by the adjusting wheel 2821 to adjust the distance between the two adjusting seats 283, so that the two clamping blocks 284 move in the opposite direction. The rubber wheel 288 will no longer clamp the copper tube, and the copper tube can be quickly removed for subsequent processing.

[0031] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
