Description

Technical Field

[0001] This utility model relates to the technical field of condenser copper tube processing equipment, specifically a positionable copper tube cutting device for processing air conditioner condensers. Background Technology

[0002] The copper tubes in the air conditioner condenser are the core components for heat exchange. Their performance and structural design directly affect the air conditioner's cooling efficiency, durability, and overall operational stability. The core function of the air conditioner condenser is to condense the high-temperature, high-pressure gaseous refrigerant (such as Freon) produced by compression in the compressor into a liquid refrigerant through heat exchange with the outside air. The copper tubes serve as the refrigerant's flow channel and heat exchange medium.

[0003] Patent CN213318053U discloses a copper pipe cutting device for processing air conditioner condensers. The device includes: a workbench; an L-plate fixedly mounted on the top of the workbench; a motor fixedly mounted on the L-plate; a first pulley fixedly mounted on the output shaft of the motor; fixed plates fixedly mounted on one side of the L-plate; and a rotating rod. This invention provides a copper pipe cutting device for processing air conditioner condensers. By setting a moving mechanism, the baffle can maintain a specific distance from the saw blade, thus ensuring that the cut copper pipe meets the requirements. This avoids the need for workers to measure the copper pipe multiple times, simplifying the operation and greatly reducing the measurement error rate. The fixed holes can fix the copper pipe and prevent violent shaking during cutting.

[0004] However, when fixing the copper tube, the aforementioned patent limits the copper tube by fixing the fixing hole, but it cannot adjust the inner diameter of the fixing hole, making it difficult to position copper tubes of different diameters. When the diameter of the copper tube is smaller than the inner diameter of the fixing hole, the positioning effect is poor and the flexibility is poor. Utility Model Content

[0005] The purpose of this utility model is to provide a positioning copper tube cutting device for air conditioner condenser processing, so as to solve the problems mentioned in the background art, which are that the inner diameter of the fixing hole cannot be adjusted, making it difficult to position copper tubes of different diameters. When the diameter of the copper tube is smaller than the inner diameter of the fixing hole, the positioning effect is poor and the flexibility is poor.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a positionable copper pipe cutting device for processing air conditioner condensers, comprising a support box, a connecting frame, a support block, and a limiting block. The connecting frame is fixedly connected to the front and rear sides of the top of the support box. The support block is fixedly connected to the middle of the top of the support box. The limiting block is fixedly connected to the rear side of the top of the support block. A first limiting block is fixedly connected to the lower rear side of the inner wall of the connecting frame. A moving rod is slidably connected between the inner cavities of the first limiting block. An extension rod is fixedly connected to the top of the moving rod. A second limiting block is fixedly connected to the upper rear side of the inner wall of the connecting frame. Rotating shafts are fixedly connected to the left and right sides of the rear rear side of the inner wall of the connecting frame. A clamping arm is rotatably connected to the outer wall of the rotating shaft. A roller is rotatably connected to the bottom end of the clamping arm. A first clamp is rotatably connected to the top end of the clamping arm. A limiting groove is opened at the top end of the extension rod. A second clamp is rotatably connected between the inner walls of the limiting groove.

[0007] As a further description of the above technical solution: The front and rear side walls of the support box have grooves, and an electric push rod is fixedly connected to the bottom of the inner cavity of the groove.

[0008] As a further description of the above technical solution: The bottom end of the movable rod extends through the bottom of the inner cavity of the connecting frame and the top of the support box, and extends into the inner cavity of the groove.

[0009] As a further description of the above technical solution: The bottom end of the movable rod is fixedly connected to the output end of the electric push rod, and the extension rod is slidably connected to the inner cavity of the second limiting block.

[0010] As a further description of the above technical solution: A DC motor is fixedly connected to the rear bottom of the inner cavity of the support block, and a first belt roller is fixedly connected to the output end of the DC motor. A fixing hole is opened on the front top of the support block.

[0011] As a further description of the above technical solution: The front sidewall of the limiting block has a through hole in the middle, and a bearing seat is fixedly connected to the front sidewall of the limiting block. A connecting cylinder is fixedly inserted into the inner cavity of the bearing seat, and a second belt roller is fixedly sleeved on the rear side of the outer sidewall of the connecting cylinder.

A screw is inserted into the front side of the outer side wall of the connecting cylinder. A cutter head is fixedly connected to one end of the screw. Adjusting nuts are screwed to both sides of the outer side wall of the screw.

[0013] Compared with the prior art, the beneficial effects of this utility model are: This positionable copper tube cutting device for air conditioner condenser processing uses a connecting frame on a support box. Inside the connecting frame, a first limiting block and a second limiting block restrict the vertical movement of the moving rod and the extension rod. By setting clamping arms on both sides, when the electric push rod drives the moving rod to rise and fall, the first clamp on the clamping arm simultaneously clamps the copper tube. With the second clamp, copper tubes of different diameters can be clamped, and different copper tubes are kept positioned at the center position. The positioning effect is good and the flexibility is high.

[0014] This positionable copper tube cutting device for air conditioner condenser processing uses a support block between connecting frames. A limiting block is connected to the support block, and a through hole is opened in the limiting block. The limiting block is concentric with the first clamp and the second clamp. A bearing seat is set on the limiting block to connect to a connecting cylinder. An adjustable cutting head is set in the connecting cylinder and contacts the surface of the copper tube. The connecting cylinder is driven to rotate by a DC motor, so that the cutting head can cut the surface of the copper tube evenly and quickly, with good cutting effect. Attached Figure Description
