Description

Technical Field

[0001] The utility model relates to the technical field of air conditioner production, and more specifically, it relates to a cutting device for the production of air conditioner accessories. Background Art

[0002] Air conditioners, as indispensable electrical appliances in modern life, are widely used in various buildings and structures. By adjusting parameters such as indoor temperature, humidity, cleanliness, and flow rate, they provide people with a comfortable living environment. In the production process of air conditioners, the manufacture of accessories is a crucial link, which directly affects the overall performance and service life of air conditioners. Among them, copper tubes, as key components in the air conditioner refrigeration system, undertake the important task of refrigerant transmission, and their production quality and efficiency directly affect the performance and cost of air conditioners.

[0003] In the production process of air conditioner accessories, copper tubes are widely used in the pipeline connection of the refrigeration system due to their good thermal conductivity and workability. However, due to the diverse models of air conditioner units, the required lengths of copper tubes are also different. In order to meet the specific requirements of different models of air conditioners for the length of copper tubes, the copper tubes must be precisely cut during the production process. This can not only ensure that the length of the copper tubes meets the design requirements, facilitating subsequent processing and assembly, but also reduce material waste and production costs.

[0004] Although copper tube cutting is a necessary step in the production of air conditioner accessories, traditional cutting methods often have the following problems: First, burrs are easily generated on the edges of the cut copper tubes, which not only affects the appearance quality of the copper tubes but also may have an adverse impact on subsequent welding and assembly processes, reducing production efficiency; Second, since the cutting and grinding processes are separate, different equipment and different operators are required, and the practicability is poor.

[0005] Therefore, in order to solve the above technical problems, this application proposes a cutting device for the production of air conditioner accessories. Content of the Utility Model

[0006] Aiming at the deficiencies of the existing technology, the purpose of the utility model is to provide a cutting device for the production of air conditioner accessories.

[0007] To achieve the above purpose, the utility model provides the following technical solutions: It includes a cutting base for placing air conditioner copper tubes for cutting, and slots for placing and cutting copper tubes are opened on the surface of the cutting base;

[0008] It also includes a fixing member for installing the cutting member. The fixing member is rotatably connected to the cutting base. A grinding member is provided inside the cutting base, which can provide a burr grinding function for the cutting position after the copper pipe is cut. The grinding member is connected and separated from the cutting member by an adjustable limiting member to provide power, so that the cutting member drives the grinding member to perform burr grinding on the cutting position of the cut copper pipe.

[0009] In this solution, the fixing member includes a pressing frame rotatably installed outside the cutting base through a damping rotating shaft. The pressing frame is arranged in a U shape, and both sides of the open end are installed through the damping rotating shaft. A handle is installed outside the closed end of the pressing frame for easy manual grasping and pressing down. Grooves are provided at the bottom of both sides of the pressing frame corresponding to the positions on the surface of the cutting base where the copper pipe is inserted, so as to cooperate with the positions on the surface of the cutting base where the copper pipe is placed to clamp and fix the copper pipe for cutting and grinding.

[0010] A cutting member for cutting the copper pipe is rotatably installed inside the pressing frame through a connecting rod.

[0011] In this embodiment, the cutting member includes a cutting blade for cutting the copper pipe. The power input source of the cutting blade is a motor installed inside the connecting rod.

[0012] On both sides of the surface of the cutting blade, a telescopic sleeve and a telescopic rod are installed through fixing bolts. Through the contact connection between the telescopic sleeve and the telescopic rod and the limiting member provided inside the grinding member, the grinding member is driven to grind the cut copper pipe.

[0013] It should be noted that the grinding member includes a movable groove opened in the cutting base. A grinding sleeve is rotatably installed in the movable groove. The grinding sleeve is arranged in a semicircular shape, and the center position is in the shape of an open cavity for placing the copper pipe to be ground and cut. During the rotation process between the grinding sleeve and the movable groove, the grinding sleeve is slidably and rotatably connected to the corresponding limiting groove opened in the movable groove through a sliding ring arranged outside the grinding sleeve. The length dimension of the sliding ring is greater than the dimension of the semicircle formed by the movable groove, so as to prevent the sliding ring from falling off during the circular rotation process.

[0014] A rotating groove with an opening facing inward is opened between the cavity opened in the center of the grinding sleeve and the outer wall. The size of the rotating groove is larger than the outer diameter of the telescopic rod, so that the telescopic rod can rotate in the rotating groove along with the rotation of the cutting blade.

[0015] A limiting member is arranged at the bottom of the rotating groove to realize the contact with the telescopic rod to drive the rotation and grinding of the grinding sleeve.

[0016] Furthermore, the limiting member includes a chute opened at the inner bottom of the grinding sleeve. At both ends of the chute, slide rails are provided. Inside the slide rails, sliders are slidably connected through return springs. The sliders are fixedly installed at both ends of the pressing block. At a position corresponding to the interval rotating groove between the outer side of the grinding sleeve and the chute, slide rails are opened, and a clamping block that telescopically inserts into the inner bottom of the rotating groove is connected through the slider. The clamping block is magnetically connected with a rotatable magnetic strip at the position of the outer bottom of the grinding sleeve. Opposite sides of the magnetic strip are different magnetic poles. The magnetic strip is rotatably connected to the inner bottom of the cutting base through a fixed-angle rotating shaft, and the fixed-angle rotating shaft penetrates through the outer side of the cutting base;

[0017] The fixed-angle rotating shaft can only rotate by an angle of 180°, realizing the switching between the magnetic poles on both sides of the magnetic strip.

[0018] Wherein, the telescopic sleeve is in a cavity shape, and a section of threaded groove is opened at the inner side of the opening position. The telescopic rod is slidably inserted into the telescopic sleeve, and threaded strips are provided at the positions corresponding to the bottom end inserted into the telescopic sleeve and the position where the top end extends backward of the telescopic rod. Through the adaptation between the threaded strips provided at both ends of the telescopic rod and the threaded groove at the top end of the telescopic sleeve, the telescopic and fixing of the telescopic rod in the telescopic sleeve are realized.

[0019] Compared with the prior art, the present utility model has the following beneficial effects:

[0020] 1. Synchronous combination of cutting and grinding: By connecting the cutting member and the grinding member through an adjustable limiting member, the present utility model realizes the synchronous progress of cutting and grinding. This design effectively improves the production efficiency, reduces the steps in the production process, and avoids the cumbersome process of separately grinding the copper pipe after cutting.

[0021] 2. Improve cutting accuracy and grinding quality: Since the cutting member and the grinding member are driven by the same power source (motor), and the connection relationship between them is adjustable, the position and strength of grinding can be accurately controlled during cutting, improving the cutting accuracy and grinding quality, and ensuring the flatness and smoothness of the cutting surface of the copper pipe.

[0022] 3. Compact structure and easy operation: The cutting device adopts a rotating connection between the pressing frame and the cutting base, and the handle design on the pressing frame, making the overall structure of the device compact and easy to operate. At the same time, by adjusting the lengths of the telescopic sleeve and the telescopic rod, the cutting and grinding of copper pipes with different lengths can be easily realized, enhancing the versatility and flexibility of the device.

[0023] 4. Safe, reliable and easy to maintain: Components such as the damping rotating shaft and the return spring used in the device not only improve the stability and reliability of the device, but also facilitate the maintenance and repair of the device. In addition, the sliding and rotating connection design between the grinding sleeve and the movable groove ensures that the grinding process will not cause detachment, further improving the safety of the device.

Detailed Description of the Embodiments

[0033] As Figure 1-7 shown, the present utility model provides a cutting device for the production of air-conditioning accessories, including a cutting base 1 for placing air-conditioning copper pipes for cutting, and a slot 2 for placing and cutting copper pipes is provided on the surface of the cutting base 1;

[0034] It further includes a fixing member for installing a cutting member, the fixing member is rotatably connected to the cutting base 1, a grinding member for providing a burr grinding function to the cutting position after cutting the copper pipe is provided inside the cutting base 1, and a power connection and separation between the grinding member and the cutting member are provided through an adjustable limiting member, so that the cutting member drives the grinding member to perform burr grinding on the cutting position of the copper pipe after cutting.

[0035] The fixing member includes a pressing frame 4 rotatably mounted on the outside of the cutting base 1 through a damping rotating shaft 3. The pressing frame 4 is arranged in a U shape, and both sides of the open end are mounted through the damping rotating shaft 3. A handle for manual grasping and pressing downward is mounted on the outside of the closed end of the pressing frame 4. Grooves are provided at the bottom of both sides of the pressing frame 4 corresponding to the positions where the copper pipes are inserted into the surface of the cutting base 1, so as to cooperate with the positions where the copper pipes are placed on the surface of the cutting base 1 to clamp and fix the copper pipes to be cut and polished.

[0036] A cutting member for cutting the copper pipe is rotatably mounted inside the pressing frame 4 through a connecting rod 7.

[0037] The cutting member includes a cutting blade 8 for cutting the copper pipe. The power input source of the cutting blade 8 is a motor installed inside the connecting rod 7.

[0038] On both sides of the surface of the cutting blade 8, a telescopic sleeve 6 and a telescopic rod 22 are installed through fixing bolts. By the abutting connection between the telescopic sleeve 6 and the telescopic rod 22 and the limiting member arranged inside the grinding member, the grinding member is driven to grind the cut copper pipe.

[0039] The grinding member includes a movable groove 13 opened in the cutting base 1. A grinding sleeve 9 is rotatably mounted in the movable groove 13. The grinding sleeve 9 is arranged in a semi-circular shape, and the central position is in the shape of an open cavity for placing the copper pipes to be ground and cut. During the rotation between the grinding sleeve 9 and the movable groove 13, the grinding sleeve 9 is slidably and rotatably connected in the limiting groove correspondingly opened in the movable groove 13 through a sliding ring 5 arranged on the outside of the grinding sleeve 9 for limiting. And the length dimension of the sliding ring 5 is greater than the dimension of the semi-circle formed by the movable groove 13, so as to prevent the sliding ring 5 from falling off during the circular rotation.

[0040] An opening-innward rotating groove 11 is opened between the cavity opened in the center of the grinding sleeve 9 and the outer wall. The dimension of the rotating groove 11 is greater than the outer diameter of the telescopic rod 22, so that the telescopic rod 22 can rotate in the rotating groove 11 along with the rotation of the cutting blade 8.

[0041] A limiting member is arranged at the bottom inside the rotating groove 11 to realize the abutting connection with the telescopic rod 22 to drive the rotation and grinding of the grinding sleeve 9.

[0042] The limiting member includes a chute 18 opened at the inner bottom of the grinding sleeve 9. At both ends of the chute 18, slide rails 21 are opened. Inside the slide rails 21, sliders 20 are slidably connected through return springs 19. The sliders 20 are fixedly installed at both ends of the pressing block 15. At a position corresponding to the interval between the outer side of the grinding sleeve 9 and the rotating groove 11 of the chute 18, slide rails 21 are opened, and a clamping block 16 that telescopically inserts into the inner bottom of the rotating groove 11 is connected through the sliders 20. The clamping block 16 is magnetically connected with a rotatable magnetic strip 17 at the bottom position of the outer side of the grinding sleeve 9. Opposite sides of the magnetic strip 17 are different magnetic poles. The magnetic strip 17 is rotatably connected to the inner bottom of the cutting base 1 through a fixed-angle rotating shaft 14, and the fixed-angle rotating shaft 14 penetrates the outer side of the cutting base 1;

[0043] The fixed-angle rotating shaft 14 can only rotate at a rotation angle of 180°, realizing the switching between the magnetic poles on both sides of the magnetic strip 17.

[0044] The telescopic sleeve 6 is in a cavity shape, and a section of threaded groove is opened inside the opening position. The telescopic rod 22 is slidably inserted into the telescopic sleeve 6, and threaded strips are provided at positions corresponding to the inner bottom end of the telescopic sleeve 6 where the telescopic rod 22 is inserted and the position where the top end extends backward. Through the matching between the threaded strips provided at both ends of the telescopic rod 22 and the threaded groove at the top end of the telescopic sleeve 6, the telescopic and fixing of the telescopic rod 22 in the telescopic sleeve 6 are realized.

[0045] Working principle: During cutting work: Lift the pressing frame 4, place the copper pipe to be cut on the slot 2 opened on the surface of the cutting base 1 and on the arc-shaped inwardly concave surface of the grinding sleeve 9, then start the motor of the cutting blade 8, grab the pressing frame 4 and drive the cutting blade 8 to cut the copper pipe;

[0046] During the cutting process, the telescopic rod 22 is completely inserted into the telescopic sleeve 6, and the length of the telescopic sleeve 6 is shorter than half of the width of the cutting groove 10. Therefore, when the telescopic rod 22 is fully telescoped in the telescopic sleeve 6 to cut the copper pipe, the telescopic sleeve 6 will not drive the rotation of the grinding sleeve 9.

[0047] When grinding after cutting is completed: At this time, there are two grinding methods:

[0048] A. Use the grinding sleeve 9 to grind the outer ring of the cut copper tube: After rotating the telescopic rod 22 counterclockwise for a period, separate the threaded bar at the top of the telescopic rod 22 from the threaded groove at the top of the telescopic sleeve 6, then pull the telescopic rod 22 outwards from the telescopic sleeve 6 until the threaded bar at the bottom of the telescopic rod 22 meshes with the threaded groove at the top of the telescopic sleeve 6, and continue to rotate a certain distance to fix the length of the telescopic rod 22 extending from the telescopic sleeve 6. Then rotate the fixed-angle rotating shaft 14. After the fixed-angle rotating shaft 14 rotates 180°, face the side of the magnetic strip 17 with the opposite magnetism to the bottom of the clamping block 16 towards the bottom surface of the clamping block 16. At this time, under the principle of like poles repelling each other, the clamping block 16 is pushed upwards and thus inserted into the rotating groove 11 to separate the two ends in the rotating groove 11. Then start the motor to drive the cutting blade 8 to rotate, and use an additional fixed clamping structure to rotatably fix the cut copper tube in the grinding sleeve 9 on one side of the cutting base 1. The rotatable fixed clamping structure is a well-known prior art and will not be elaborated here. After fixing other copper tubes handheld or also using the fixed clamping structure in the grinding sleeve 9 on the other side, during the rotation of the cutting blade 8, the telescopic rod 22 rotates accordingly and rotates in the rotating groove 11. After the telescopic rod 22 rotates in the rotating groove 11 and touches the clamping block 16, it will drive the entire grinding sleeve 9 to rotate under the restriction of the clamping block 16. And the grinding sleeve 9 can only rotate and grind within the movable groove 13 under the restriction of the slip ring 5 during the rotation process, and the copper tube can be slowly rotated and ground during the grinding process;

[0049] B. Use both sides of the cutting blade 8 to grind the cut of the cut copper tube: Rotate the fixed-angle rotating shaft 14. After facing the side of the magnetic strip 17 with the opposite magnetism to the bottom of the clamping block 16 towards the bottom of the clamping block 16, press down the pressing block 15. The pressing block 15 drives the slider 20 to slide in the slide rail 21 and compress the return spring 19, so that the pressing block 15 slides downwards in the chute 18. The pressing block 15 presses down the clamping block 16, and the clamping block 16 is adsorbed by the opposite magnetic pole and contracts from the rotating groove 11 during the process of being pressed downwards. At this time, after fixing the copper tube, start the cutting blade 8. At this time, grinding sheets can be installed on both sides of the cutting blade 8 through bolts to grind the cutting port of the cutting blade 8. And the telescopic rod 22 will directly rotate in the rotating groove 11 without driving the grinding sleeve 9 to rotate, realizing cutting and grinding of the cut copper tube.
