Description

Technical Field

[0001] This utility model relates to a PTC auxiliary electric heater aluminum tube cutting device. Background Technology

[0002] PTC (Positive Temperature Coefficient) auxiliary electric heaters, as efficient and safe heating elements, are widely used in household air conditioners, central air conditioning systems, new energy vehicle air conditioning, and battery thermal management systems. Their core structure typically includes an aluminum heat dissipation tube, an embedded PTC ceramic heating element, and an electrode connection structure. The aluminum tube, as a key heat dissipation carrier, not only needs excellent thermal conductivity but also strict requirements for dimensional accuracy, port flatness, and surface integrity. The length accuracy of the aluminum tube directly affects the subsequent assembly positioning and electrical contact reliability of the PTC heating element, while burrs, deformation, or surface scratches on the cut surface can lead to decreased insulation performance, poor thermal contact, or even safety hazards.

[0003] Currently, the industry mainly uses small metal tube cutting machines for cutting aluminum tubes for PTC heaters. The aluminum tubes are fixed by clamping devices before cutting. Although such equipment improves cutting efficiency, the length setting method mostly relies on mechanical stops or manual measurement, which is inconvenient to adjust and has poor repeatability and positioning accuracy. The changeover adjustment time can be as long as 30 minutes or more.

[0004] Therefore, a PTC-assisted electric heater aluminum tube cutting device is proposed. Utility Model Content

[0005] The purpose of this utility model is to provide a PTC auxiliary electric heater aluminum tube cutting device to solve the problem mentioned in the background art that small metal tube cutting machines often use mechanical blocks or manual measurement for length setting, which is inconvenient to adjust and has poor repeatability and positioning accuracy.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a PTC auxiliary electric heater aluminum tube cutting device, comprising: The conveying platform is equipped with a guide assembly, which forms a conveying channel for the aluminum tube to pass through; A cutting stand is located on the downstream side of the carrying conveyor table. The cutting stand is provided with a cutting assembly and a cutting channel for aluminum tubes to pass through. The cutting assembly includes a cutting disc and a lifting drive device for driving the cutting disc to rise and fall. The lifting drive device is used to adjust the cutting height of the cutting disc. The length adjustment assembly includes a limiting platform and a translation drive device for driving the limiting platform to reciprocate along the aluminum tube conveying direction. The limiting platform is provided with a limiting channel for the aluminum tube to pass through, and the limiting platform is used to abut against the end of the aluminum tube to limit the cutting length. The conveyor belt extends to the cutting channel; The conveying channel, cutting channel, and limiting channel are connected in sequence, and the height of the conveying channel is lower than that of the cutting channel, and the upper surface of the conveyor belt is not higher than the bottom of the conveying channel.

[0007] Preferably, the guiding assembly includes two sets of parallel guide seats, and the gap between the two sets of guide seats forms the conveying channel.

[0008] Preferably, the lifting drive device includes a height adjustment seat fixed to the cutting seat and located above the guide seat. A height adjustment motor is provided on the upper part of the height adjustment seat, and a lead screw is provided at the output end of the height adjustment motor. The lead screw is connected to the bearing plate through a threaded cylinder.

[0009] Preferably, the cutting assembly further includes a cutting motor located on the support plate, and the output shaft of the cutting motor is connected to the rotating shaft of the cutting disc via a transmission belt.

[0010] Preferably, the translation drive device includes a length adjustment motor located on the back side of the cutting seat. The output end of the length adjustment motor is connected to the inner threaded sleeve via an adjustment screw. The inner threaded sleeve is located on the limiting platform, so that the length adjustment motor drives the limiting platform to translate through the inner threaded sleeve.

[0011] Preferably, the length adjustment assembly further includes at least one guide rod, which is arranged parallel to the adjustment screw. One end of the guide rod is connected to the limiting platform, and the other end is slidably sleeved in the sleeve, which is fixedly connected to the cutting seat.

[0012] Preferably, the guide rod is provided with scale markings.

[0013] Preferably, the conveyor belt extends below the cutting channel through the limiting channel.

[0014] Compared with the prior art, the beneficial effects of this utility model are: Compared with traditional mechanical stops or manual measurement, the length adjustment component (such as a limit table and translation drive device) provides more precise length control and rapid length adjustment, reducing the time for changeover and adjustment and greatly improving work efficiency.

[0015] The translation drive mechanism drives the limiting stage to reciprocate along the conveying direction. Combined with the scale markings on the guide rod, high-precision adjustment of the cutting length and high repeatability are achieved. The high length adjustment resolution and repeatability significantly improve cutting accuracy and production efficiency, reducing scrap rates caused by dimensional errors. The structural design of the translation drive mechanism and guide rod enables rapid length adjustment and shape change. It can adapt to aluminum tubes of different specifications and sizes, exhibiting strong versatility and suitability for various production environments and needs.

[0016] The guide assembly design ensures the aluminum tube remains stable during cutting, preventing cutting errors caused by tube misalignment or instability. This guarantees the length accuracy and end flatness of the aluminum tube, avoiding problems such as burrs, deformation, or scratches, and improving the quality of the cut surface.

[0017] By using a lifting drive device to adjust the cutting height and position of the cutting disc, the system can precisely control the cutting depth, avoiding the instability and errors of traditional manual adjustment and ensuring the stability of cutting quality. Attached Figure Description

[0020] To address the problems of inconvenient adjustment and poor repeatability in small metal pipe cutting machines that often rely on mechanical stops or manual measurement for length setting, this invention provides a PTC-assisted electric heater aluminum pipe cutting device. The technical solutions of this invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this invention, not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this invention without creative effort are within the scope of protection of this invention.

[0021] Please see Figure 1-6 This utility model provides a PTC auxiliary electric heater aluminum tube cutting device, comprising: The conveying platform 1 is equipped with a guide assembly 2, which forms a conveying channel 22 for aluminum tubes to pass through. The guide assembly 2 includes two sets of parallel guide seats 21, and the gap between the two sets of guide seats 21 constitutes the conveying channel 22.

[0022] A cutting seat 3 is located downstream of the conveyor platform 1. The cutting seat 3 includes a cutting assembly 31 and a cutting channel 32 for aluminum tubes to pass through. The cutting assembly 31 includes a cutting disc 311 and a lifting drive device 312 for driving the cutting disc 311 to rise and fall. The lifting drive device 312 is used to adjust the cutting height of the cutting disc 311. The lifting drive device 312 includes a height adjustment seat 3121 fixed to the cutting seat 3 and located above the guide seat 21. A height adjustment motor 3122 is located on the upper part of the height adjustment seat 3121. A lead screw 3123 is provided at the output end of the height adjustment motor 3122. The lead screw 3123 is connected to the support plate 3125 via a threaded cylinder 3124. The cutting assembly 31 also includes a cutting motor 313 located on the support plate 3125. The output shaft of the cutting motor 313 is connected to the rotating shaft 315 of the cutting disc 311 via a transmission belt 314.

[0023] The length adjustment assembly 4 includes a limiting platform 41 and a translation drive device 42 for driving the limiting platform 41 to reciprocate along the aluminum tube conveying direction. The limiting platform 41 has a limiting channel 411 for the aluminum tube to pass through, and the limiting platform 41 is used to abut against the end of the aluminum tube to limit the cutting length. The translation drive device 42 includes a length adjustment motor 421 located on the back side of the cutting seat 3. The output end of the length adjustment motor 421 is connected to an inner threaded sleeve 423 through an adjusting screw 422. The inner threaded sleeve 423 is located on the limiting platform 41, so that the length adjustment motor 421 drives the limiting platform 41 to translate through the inner threaded sleeve 423. The length adjustment assembly 4 also includes at least one guide rod 43, which is arranged parallel to the adjusting screw 422. One end of the guide rod 43 is connected to the limiting platform 41, and the other end is slidably sleeved in a sleeve 44. The sleeve 44 is fixedly connected to the cutting seat 3. The guide rod 43 is provided with a scale mark 431.

[0024] The conveyor belt 5 extends to the cutting channel 32; the conveyor belt 5 extends below the cutting channel 32 through the limiting channel 411.

[0025] The conveying channel 22, the cutting channel 32, and the limiting channel 411 are connected in sequence, and the height of the conveying channel 22 is lower than that of the cutting channel 32, and the upper surface of the conveyor belt 5 is not higher than the bottom of the conveying channel 22.

[0026] The working principle of the PTC auxiliary electric heater aluminum tube cutting device provided by this utility model is as follows: Aluminum tube placement: The aluminum tube to be cut is conveyed through the conveying channel 22 formed by the guide assembly 2 of the conveying platform 1. When the aluminum tube enters the limiting channel 411 of the limiting platform 41 along the conveying channel 22, the conveying of the aluminum tube stops when the end of the aluminum tube abuts against the limiting platform 41, and the aluminum tube is precisely positioned at the cutting position.

[0027] The cutting assembly 31 begins operation. The cutting motor 313 starts, driving the rotating shaft 315 of the cutting disc 311 to rotate via the transmission belt 314, bringing the cutting disc 311 to a suitable cutting speed. Simultaneously, the height adjustment motor 3122 of the lifting drive device 312 drives the lead screw 3123 to rotate. The lead screw 3123, through the threaded cylinder 3124, moves the support plate 3125 downward, causing the cutting disc 311 to gradually approach the aluminum tube. When the cutting disc 311 contacts the aluminum tube, the cutting operation begins. During the cutting process, the combination of the rotation and lifting motion of the cutting disc 311 enables the aluminum tube to be cut quickly and accurately. Because the height of the cutting disc 311 can be precisely adjusted, it can accommodate aluminum tubes with different outer diameters and cutting depth requirements, ensuring cutting quality.

[0028] After cutting, the height adjustment motor 3122 of the lifting drive device 312 drives the lead screw 3123 to rotate in the opposite direction, causing the support plate 3125 to lift the cutting disc 311 back to its initial position. At this time, the cut aluminum tube segment falls vertically from the cutting channel 32 onto the conveyor belt 5 under its own gravity. The conveyor belt 5 continues to run, smoothly transporting the cut aluminum tube segment to the downstream of the equipment, completing the discharge process.

[0029] Length positioning: The position of the limiting stage 41 is precisely adjusted by the translation drive device 42 according to the pre-input cutting length parameters. The length adjusting motor 421 drives the adjusting screw 422 to rotate, and the adjusting screw 422 drives the limiting stage 41 to move back and forth along the aluminum tube conveying direction through the inner threaded sleeve 423, thereby realizing precise control of the cutting length.

[0030] The guiding mechanism consisting of guide rod 43 and sleeve 44 ensures the stability and accuracy of the limiting platform 41 during movement. Meanwhile, the scale markings 431, with clear scale lines and numerical values, clearly display the position of the limiting platform 41 on the guide rod. Operators can quickly understand the current movement distance and position status of the limiting platform 41 by observing the scale markings 431.

[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.
