Description

Technical Field

[0001] This utility model relates to the field of air conditioning production and processing technology, and in particular to a copper tube processing and cutting device for air conditioning liquid receivers. Background Technology

[0002] An air conditioner is a device used to regulate indoor air temperature, humidity, cleanliness, and airflow speed. It controls the indoor environment through both cooling and heating to provide comfortable living and working conditions. The copper pipe of the air conditioner receiver is an important component of the air conditioning system. It is mainly used to store refrigerant and plays a role in gas-liquid separation, filtration, noise reduction, and refrigerant buffering. In the production and processing of air conditioners, the copper pipe of the air conditioner receiver usually needs to be cut and processed by a corresponding cutting device.

[0003] For example, utility model patent application number 202320753944.0 discloses a cutting device for processing copper pipes of air conditioner liquid receivers, including a base plate, two placement plates installed on the top of the base plate, a mounting frame installed on the inner side of the two placement plates at the top of the base plate, a cylinder installed at the bottom of the mounting frame, a cutting tool installed at the bottom of the cylinder, and a mounting seat provided on one side of the mounting frame.

[0004] Based on existing technology, most existing copper tube processing and cutting devices for air conditioning liquid receivers have a single mechanism and cannot effectively protect the cutting position during the cutting process, resulting in cutting debris easily flying and causing injury to the human body, which is not safe. In addition, they cannot continuously cut multiple sets of copper tubes for air conditioning liquid receivers, resulting in reduced cutting efficiency and low practicality. Therefore, this utility model proposes an air conditioning liquid receiver copper tube processing and cutting device to solve the problems existing in the prior art. Utility Model Content

[0005] To address the aforementioned problems, the purpose of this utility model is to propose a copper tube processing and cutting device for air conditioning liquid receivers. This device solves the problems of existing copper tube processing and cutting devices for air conditioning liquid receivers failing to effectively protect the cutting position during the cutting process, resulting in easily flying cutting debris that could cause injury to the human body, and failing to continuously cut multiple sets of copper tubes for air conditioning liquid receivers, leading to reduced cutting efficiency.

[0006] To achieve the purpose of this utility model, the utility model is implemented through the following technical solution: a copper tube processing and cutting device for an air conditioner liquid receiver, including a machine base, a frame fixed at the top of the machine base, and clamping frames slidably provided on both sides of the top of the machine base, which are driven to move by a horizontal adjustment mechanism. A copper tube clamping mechanism is provided on the clamping frames. A lifting plate driven to move by a hydraulic cylinder is provided below the frame. A drive box is fixed at the bottom of the lifting plate. A cutting tool driven to move by a longitudinal adjustment mechanism is slidably provided at the bottom of the drive box. A cutting seat located below the cutting tool is fixed at the top of the machine base. Copper tube placement slots are equidistantly opened at the top of the cutting seat. A frame plate is fixed at the bottom of the lifting plate. A protective cover is slidably provided on the inner side of the frame plate.

[0007] Further improvements include: sliders are fixed on the outer walls of all four sides of the protective cover; grooves adapted to the sliders are opened on the inner walls of all four sides of the frame plate; and copper pipe through grooves adapted to the copper pipe placement grooves are opened at equal intervals on both sides of the bottom end of the protective cover.

[0008] A further improvement is that the longitudinal adjustment mechanism includes a first lead screw rotatably connected inside the drive box and driven to rotate by a motor, and a threaded block threaded onto the first lead screw. The bottom end of the threaded block slides through the bottom end of the drive box and is fixed to the top of the cutting tool.

[0009] A further improvement is that the frame includes support rods symmetrically fixed to the top of the machine platform and support plates fixed to the top of the support rods, and a first limiting rod that slides through the support plate is symmetrically fixed to the top of the lifting plate.

[0010] A further improvement is that the transverse adjustment mechanism includes a second lead screw rotatably connected to both sides inside the machine tool and driven to rotate by a first turntable, and a threaded plate threaded onto the second lead screw. The top of the threaded plate slides through the top of the machine tool and is fixed to the bottom of the clamping frame.

[0011] A further improvement is made in that: the copper tube clamping mechanism includes a third lead screw threaded through the top of the clamping frame and a second turntable fixed to the top of the third lead screw. A pressure plate is rotatably connected to the bottom of the third lead screw. Arc-shaped pressure blocks are fixed at equal intervals at the bottom of the pressure plate. A support seat is fixed to the bottom of the inner side of the clamping frame. Arc-shaped grooves corresponding to the arc-shaped pressure blocks are opened at equal intervals at the top of the support seat. A second limiting rod that slides through the top of the clamping frame is symmetrically fixed to the top of the pressure plate.

[0012] A further improvement is that the cutting tool includes a concave frame fixed to the bottom of the threaded block and a cutting motor fixed to the outer wall of the concave frame. The output end of the cutting motor passes through the concave frame via a bearing and is fixed with a cutting blade.

[0013] The beneficial effects of this utility model are as follows: This utility model includes a machine base, which is driven by a hydraulic cylinder to lower the lifting plate. During the descent of the lifting plate, the frame plate at its bottom end is driven to descend, so that the bottom end of the protective cover contacts the top end of the machine base, thereby forming a protective structure on the outside of the cutting seat. This effectively blocks the flying debris during the cutting process, providing protection and preventing injury to the human body. It has a high level of safety. Furthermore, by opening copper pipe placement slots at equal intervals at the top of the cutting seat for placing the copper pipes of the air conditioning liquid reservoir, and by driving the cutting tool to move from front to back through a longitudinal adjustment mechanism, continuous cutting processing of each group of air conditioning liquid reservoir copper pipes on the cutting seat can be achieved, which improves the cutting processing efficiency and has high practicality.

[0020] To deepen the understanding of this utility model, the following detailed description will be provided in conjunction with embodiments. These embodiments are only used to explain this utility model and do not constitute a limitation on the scope of protection of this utility model.

[0021] according to Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5As shown, this embodiment provides a copper tube processing and cutting device for air conditioner liquid receivers, including a hollow machine base 1 and a frame 2 fixed to the middle of the top of the machine base 1 by bolts. Clamping frames 3 are slidably provided on both the left and right sides of the top of the machine base 1, and the clamping frames 3 are driven by a horizontal adjustment mechanism to slide and move on the upper surface of the machine base 1. The clamping frames 3 are provided with a copper tube clamping mechanism for clamping and fixing the copper tube of the air conditioner liquid receiver to be cut. A hydraulic cylinder 4 is fixed to the frame 2 by bolts, and a lifting plate 5 located below the frame 2 is fixed to the bottom of the hydraulic cylinder 4 by bolts. The lifting plate 5 is driven by the hydraulic cylinder 4 to move up and down. A hollow drive box 6 is fixed to the bottom of the lifting plate 5 by bolts. A cutting tool 7 for cutting the copper tube of the air conditioner liquid receiver is slidably provided at the bottom of the drive box 6, and the cutting tool 7 is driven by a longitudinal adjustment mechanism to move longitudinally forward of the bottom of the drive box 6. A cutting seat 8 is fixed to the middle of the top of the machine base 1 by bolts, and the cutting seat 8 is located below the cutting tool 7. Furthermore, a cutting groove adapted to the cutting tool 7 is provided on the cutting base 8. A copper tube placement groove 9 for placing the copper tubes of the air conditioner liquid reservoir to be cut is provided at the top of the cutting base 8. There are five sets of copper tube placement grooves 9, and the five sets of copper tube placement grooves 9 are equidistantly distributed. By opening the copper tube placement grooves 9 for placing the copper tubes of the air conditioner liquid reservoir at equidistantly on the top of the cutting base 8, and driving the cutting tool 7 to move from front to back through the longitudinal adjustment mechanism, continuous cutting processing of each set of air conditioner liquid reservoir copper tubes on the cutting base 8 can be achieved. The bottom end of the lifting plate 5 is fixed with a frame plate 10 located outside the drive box 6 by bolts. A protective cover 11 for protecting the cutting position is slidably provided on the inner side of the frame plate 10. The protective cover 11 can slide inside the frame plate 10. The lifting plate 5 is driven to descend by the hydraulic cylinder 4. During the descent of the lifting plate 5, the frame plate 10 at its bottom end is driven to descend, so that the bottom end of the protective cover 11 contacts the top of the machine base 1, thereby forming a protective structure outside the cutting base 8, which can effectively block the flying debris during the cutting process.

[0022] The protective cover 11 has sliders 12 welded and fixed on the outer walls of the front, back, left and right sides. The frame plate 10 has grooves 13 on the inner walls of the front, back, left and right sides. The grooves 13 are adapted to the sliders 12. The sliders 12 slide in the grooves 13 to limit the protective cover 11 and prevent the protective cover 11 from falling off the frame plate 10. The bottom left and right sides of the protective cover 11 have copper tube through grooves 14 that are evenly distributed. The copper tube through grooves 14 are adapted to the copper tube placement grooves 9. When the protective cover 11 is placed outside the cutting seat 8, the two ends of the air conditioner liquid receiver copper tube can pass through the copper tube placement grooves 9.

[0023] The longitudinal adjustment mechanism includes a first lead screw 16, a motor 15, and a threaded block 17. The first lead screw 16 is rotatably connected to the inside of the drive box 6 via a bearing. The motor 15 is fixed to the rear outer wall of the drive box 6 by bolts. The rear end of the first lead screw 16 passes through the drive box 6 via a bearing and is fixedly connected to the output end of the motor 15. The threaded block 17 is threaded onto the first lead screw 16. The bottom end of the threaded block 17 slides through the bottom end of the drive box 6 and is fixed to the top end of the cutting tool 7 by bolts. The bottom end of the drive box 6 has a through groove that matches the threaded block 17 so that the threaded block 17 can slide through. The first lead screw 16 is driven to rotate by the motor 15, so that the threaded block 17 threaded onto the first lead screw 16 drives the cutting tool 7 to move longitudinally back and forth.

[0024] The frame 2 includes support rods 201 and support plates 202. The support rods 201 are provided in four sets and are symmetrically fixed to the top of the machine base 1 with bolts. The support plates 202 are fixed to the top of the four sets of support rods 201 with bolts. The support rods 201 provide stable support for the support plates 202. The top of the lifting plate 5 is welded and fixed with four sets of symmetrically distributed first limiting rods 18. The top of the first limiting rods 18 slides through the support plates 202, which plays a limiting role for the lifting plate 5, making the lifting plate 5 more stable during the lifting process.

[0025] The lateral adjustment mechanism includes a first turntable 19, a second lead screw 20, and a threaded plate 21. The first turntable 19 is rotatably connected to the left and right sides inside the machine base 1 via bearings. The opposite ends of the two sets of second lead screws 20 are passed through bearings to the outside of the machine base 1 and fixedly connected to the first turntable 19 with bolts. The threaded plate 21 is threaded onto the second lead screw 20. The top of the threaded plate 21 slides through the top of the machine base 1 and is fixed to the bottom of the clamping frame 3 with bolts. The top of the machine base 1 has a through groove that matches the threaded plate 21. By rotating the first turntable 19, the second lead screw 20 is driven to rotate, causing the threaded plate 21 threaded onto the second lead screw 20 to drive the clamping frame 3 to move laterally.

[0026] The copper tube clamping mechanism includes a third lead screw 22 and a second turntable 23. The third lead screw 22 is threaded through the top of the clamping frame 3. The second turntable 23 is fixed to the top of the third lead screw 22 by bolts. The bottom of the third lead screw 22 is rotatably connected to a pressure plate 24 located inside the clamping frame 3 via a bearing. The bottom of the pressure plate 24 is welded and fixed with arc-shaped pressure blocks 25 distributed at equal intervals. The bottom of the inner side of the clamping frame 3 is fixed with a support seat 26. The top of the support seat 26 is provided with arc-shaped grooves at equal intervals, and the arc-shaped grooves correspond one-to-one with each arc-shaped pressure block 25. By rotating the second turntable 23, the third lead screw 22 is driven to rotate downward. The third lead screw 22 then drives the pressure plate 24 to descend, and together with the support seat 26, it clamps and fixes the copper tube of the air conditioner liquid receiver. The top of the pressure plate 24 is symmetrically fixed with a second limiting rod 27, and the top of the second limiting rod 27 slides through the top of the clamping frame 3, which plays a limiting role on the pressure plate 24, making the pressure plate 24 more stable during the lifting and lowering process.

[0027] The cutting tool 7 includes a concave frame 701 and a cutting motor 702. The concave frame 701 is fixed to the bottom of the threaded block 17 by bolts, and the cutting motor 702 is fixed to the outer right side wall of the concave frame 701 by bolts. The output end of the cutting motor 702 passes through the concave frame 701 through a bearing and is fixed with a cutting blade 703. The cutting motor 702 drives the cutting blade 703 to rotate, so as to realize the cutting processing of the copper pipe of the air conditioner liquid receiver.

[0028] When it is necessary to cut the copper tubes of the air conditioner liquid receiver during the air conditioner production process, first place each group of air conditioner liquid receiver copper tubes to be cut into the copper tube placement groove 9 at the top of the cutting seat 8. Then, use the horizontal adjustment mechanism to drive the clamping frames 3 on both sides of the top of the machine base 1 to move to the left and right ends of the air conditioner liquid receiver copper tubes respectively, and use the copper tube clamping mechanism to clamp and fix the air conditioner liquid receiver copper tubes. Then, start the hydraulic cylinder 4 to drive the lifting plate 5 to descend. During the descent of the lifting plate 5, it drives the frame plate 10 at its bottom to descend until the bottom of the protective cover 11 is aligned with the frame plate 10 at its bottom. When the top of the machine base 1 contacts the cutting seat 8, a protective structure is formed on the outside of the cutting seat 8. The lifting plate 5 continues to descend until the cutting tool 7 descends to the cutting groove position on the cutting seat 8. At this time, the cutting tool 7 is located at the frontmost side (due to the sliding connection between the frame plate 10 and the protective cover 11, the protective cover 11 will not obstruct the descent of the cutting tool 7). Then, the longitudinal adjustment mechanism drives the cutting tool 7 to move from front to back, and cuts the copper pipe of the air conditioner liquid receiver during the movement until all the copper pipes of each group of air conditioner liquid receivers are cut.
