Description

Technical Field

[0001] This utility model relates to the technical field of copper pipe cutting mechanisms, and in particular to a pipe cutting device for refrigeration and air conditioning. Background Technology

[0002] Cutting machines are indispensable equipment in some light industries. Traditionally, a cutting machine is a machine that uses the force of mechanical movement to press against a die to punch and shape non-metallic materials. Modern cutting machines have undergone some changes, incorporating advanced technologies such as high-pressure water jets and ultrasonic waves into leather cutting technology. However, these devices are still categorized as cutting machines. Highly automated cutting equipment includes computer-controlled moving head cutting machines, laser cutting machines (vibrating blades), high-pressure water jet cutting machines, and computer-controlled cutting machines. These typically use clamping plates to compress and limit the copper tube to keep it stable.

[0003] Regarding the aforementioned technologies, the existing copper pipe cutting mechanism has the following drawback: during the processing of copper pipes of different diameters, when the side of the clamping plate abuts against the surface of the copper pipe, it usually only supports the surface of the copper pipe at two directional fulcrums. This causes the copper pipe to tilt or move under the action of external force during the cutting process, resulting in cutting deformation. Therefore, this utility model provides a pipe cutting device for refrigeration and air conditioning. Utility Model Content

[0004] The purpose of this application is to provide a pipe cutting device for refrigeration and air conditioning, so as to solve the problem mentioned in the background art that, when the side of the clamping plate abuts against the surface of the copper pipe during the processing of copper pipes of different diameters, the surface of the copper pipe is usually supported by two fulcrums in two directions, which causes the copper pipe to tilt or move under the action of external force during the cutting of the copper pipe, resulting in cutting deformation.

[0005] To achieve the above objectives, this application provides the following technical solution: a pipe cutting device for refrigeration and air conditioning, comprising a base plate and a dual-axis motor. A support cylinder is provided above the base plate, and guide grooves are provided at both ends of the support cylinder. A rotating ring is slidably connected to the inner wall of the guide groove, and multiple pushing blocks are fixedly connected to the outer side of the rotating ring. Multiple clamping assemblies are provided on the inner wall of the support cylinder. The clamping assembly includes a guide rod fixedly connected to the inner wall of the support cylinder, a limit block slidably connected to the outer side of the guide rod, a sliding groove adapted to the guide rod being provided on the inner side of the limit block, and two edges of the limit block near the guide rod being arc-shaped. A spring is sleeved on the outer side of the guide rod, and the two ends of the spring are fixedly connected to the inner wall of the support cylinder and the outer side of the limit block, respectively.

[0006] Preferably, one end of the rotating ring is fixedly connected to a limiting ring, and the inner side of the support cylinder is provided with a sliding groove that matches the limiting ring.

[0007] Preferably, a pair of load-bearing rods are fixedly connected to the outer side of the support cylinder, and the load-bearing rods are fixedly connected to the dual-axis motor. Both output ends of the dual-axis motor are fixedly connected to gear rings.

[0008] Preferably, the outer side of the rotating ring is fixedly connected with a plurality of gear teeth that are adapted to the toothed ring, and the rotating ring is made of stainless steel plate.

[0009] Preferably, a load-bearing frame is fixedly connected to the top of the base plate, a hydraulic cylinder is installed on the outside of the load-bearing frame, a push plate is fixedly connected to the output end of the hydraulic cylinder, and a cutter is fixedly connected to the bottom of the push plate.

[0010] Preferably, a pair of support frames are fixedly connected to the top of the base plate. The support frames are tripods, and the top of the support frames are fixedly connected to the outside of the support cylinder.

[0011] In summary, the technical effects and advantages of this utility model are as follows:

[0012] 1. In this utility model, through the coordinated arrangement of a dual-axis motor, a gear ring, gear teeth, a rotating ring, a pushing block, a limiting block, a guide rod, and a spring, the pushing block, during its movement, pushes the limiting block along the guide rod, causing the limiting block to gradually move towards the copper tube until it abuts against the surface of the copper tube, at which point the dual-axis motor stops rotating. This achieves adaptive clamping and limiting of the copper tube from two directions at multiple points, preventing the copper tube from warping during the cutting process and maintaining the stability of the copper tube.

[0013] 2. In this utility model, the rotating ring, the limiting ring, and the sliding groove are designed in a coordinated manner to prevent the rotating ring from shifting during rotation, so that the pushing block remains stable during deflection and can provide a stable and continuous thrust to the limiting block.

[0021] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," "sleeved / connected," "connected," etc., should be interpreted broadly. For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0022] Example 1: Reference Figure 1-4The refrigeration and air conditioning pipe cutting device shown includes a base plate 1 and a dual-axis motor 5. A support cylinder 3 is arranged above the base plate 1. Guide grooves are opened at both ends of the support cylinder 3. A rotating ring 7 is slidably connected to the inner wall of the guide groove. Multiple pushing blocks 8 are fixedly connected to the outer side of the rotating ring 7. Multiple clamping assemblies are arranged on the inner wall of the support cylinder 3. The clamping assembly includes a guide rod 13 fixedly connected to the inner wall of the support cylinder 3. A limit block 9 is slidably connected to the outer side of the guide rod 13. A sliding groove 18 adapted to the guide rod 13 is opened on the inner side of the limit block 9. The two edges of the limit block 9 near the guide rod 13 are arc-shaped. A spring 14 is sleeved on the outer side of the guide rod 13. The two ends of the spring 14 are respectively connected to the support cylinder 3. The inner wall side of the cylinder 3 and the outer side of the limiting block 9 are fixedly connected to facilitate multi-point adaptive clamping and limiting of the copper tube, so that the copper tube remains stable during the cutting process; one end of the rotating ring 7 is fixedly connected to the limiting ring 17, and the inner side of the support cylinder 3 is provided with a sliding groove that matches the limiting ring 17 to prevent the rotating ring 7 from shifting during rotation; a pair of load-bearing rods 4 are fixedly connected to the outer side of the support cylinder 3, and the load-bearing rods 4 are fixedly connected to the dual-axis motor 5. Both output ends of the dual-axis motor 5 are fixedly connected to the toothed rings 6 to realize the rotation of the two rotating rings 7; multiple gear teeth 16 that match the toothed rings 6 are fixedly connected to the outer side of the rotating ring 7.

[0023] In this embodiment, the copper tube is placed between the support cylinders 3, and the dual-axis motor 5 is controlled to drive the two toothed rings 6 to rotate. The gear teeth 16 drive the rotating ring 7 to rotate, and the rotating ring 7 drives multiple push blocks 8 to deflect. The edges of the push blocks 8 push the limiting blocks 9 to slide along the guide rod 13, so that the limiting blocks 9 gradually move towards the copper tube until they abut against the surface of the copper tube, and the dual-axis motor 5 stops rotating. This achieves multi-point adaptive clamping and limiting of the copper tube from two directions, maintaining the stability of the copper tube.
