Description

Technical Field

[0001] This application relates to the field of electric heating tube manufacturing technology, specifically to a testing device for electric heating tube manufacturing. Background Technology

[0002] An electric heating element is an electrical component that converts electrical energy into heat energy. Precise testing during the production of electric heating elements is a crucial step in ensuring product quality. As the core heating component in many electrical devices, the performance of the electric heating element directly affects the user experience and safety. If the heating efficiency of the electric heating element is substandard, the electrical device will heat up slowly, reducing the user experience; if the insulation performance is defective, it may even lead to serious safety accidents such as electric leakage. Therefore, only through precise testing and strict control of various performance indicators of the electric heating element can its stable and reliable operation in practical applications be ensured.

[0003] Currently, traditional testing equipment for electric heating elements typically places the product in a designated position on a testing platform and uses a limiting baffle fixed to the side with bolts to restrict the product's position within a defined area. However, electric heating elements come in various specifications and models, and different models have different dimensions. As a result, the limiting baffle cannot flexibly adapt to the dimensions of different specifications of electric heating elements, causing the limiting baffle to be unable to effectively fix electric heating elements of different specifications. This leads to poor electrode contact between the testing equipment and the product, resulting in abnormal test data. Summary of the Invention

[0004] Technical problems to be solved

[0005] To address the shortcomings of existing technologies, this application provides a testing device for electric heating tube production, which is capable of clamping electric heating tube bodies of different specifications, thereby accommodating electric heating tubes of different sizes, significantly improving the versatility of the device, and solving the problems mentioned in the background technology.

[0006] To achieve the above objectives, this application provides the following technical solution: a testing device for electric heating tube production, comprising a chassis, a track groove on the outer side of the chassis, a movable plate slidably connected to the inner side of the track groove, a testing platform fixedly connected to the upper side of the movable plate, two sets of symmetrical adaptive clamping components on the upper side of the testing platform, an electric heating tube body placed on the upper side of the testing platform, and testing components on the outer side of the chassis.

[0007] The adaptive clamping assembly includes a bracket fixedly connected to the upper side of the detection platform. A guide rod is fixedly connected to the inner side of the bracket. Two symmetrical moving blocks are slidably connected to the outer side of the guide rod. A first spring is fixedly connected to the side of each of the two moving blocks that is far apart from each other, and the first spring is fixedly connected to the inner side of the bracket. A hinge rod is hinged to the outer side of each of the two moving blocks. A clamping frame is provided on the outside of the bracket. Two fixed shafts are fixedly connected to the upper side of the clamping frame. The other ends of the two hinge rods are rotatably connected to the outer side of the fixed shafts.

[0008] The above solution, by setting an adaptive clamping component, can flexibly adjust the clamping position and force on different specifications of electric heating tube bodies compared to traditional detection equipment with fixed limit baffles. At the same time, the sliding cooperation between the guide rod and the moving block, combined with the elastic effect of the first spring, allows the moving block to automatically adjust its position according to the size of the electric heating tube body. The clamping frame adaptively clamps electric heating tube bodies of different specifications through the hinge rod and the fixed shaft, thereby adapting to the problem of electric heating tubes of different sizes and significantly improving the versatility of the equipment.

[0009] Furthermore, a guide groove is provided on the inner side of the bracket, and the outer sides of the two moving blocks are slidably connected to the inner side of the guide groove.

[0010] The above solution uses a guide groove on the inner side of the bracket to precisely limit and guide the moving block, effectively preventing the moving block from shifting during sliding. This ensures the accuracy and reliability of the clamping frame in holding the heating element, providing a stable foundation for subsequent testing.

[0011] Furthermore, the inner side of the clamping frame is rotatably connected to a plurality of equally spaced pulleys, each of which is made of rubber.

[0012] Through the above solution, the rubber pulley can effectively avoid damaging the surface of the heating element when clamping the heating element body, thanks to the softness of the rubber material.

[0013] Furthermore, a guide rod is fixedly connected to one end of the clamping frame, and the guide rod is inclined.

[0014] With the above-mentioned scheme, the inclined guide rod allows the clamping frame to move to both sides on its own when the heating tube body moves, thus facilitating the movement of the heating tube body to a suitable position and significantly improving the convenience and efficiency of the testing operation.

[0015] Furthermore, a second electric push rod is fixedly installed on the inner side of the chassis, and a connecting plate is fixedly connected to the output end of the second electric push rod. The connecting plate is fixedly connected to the upper side of the movable plate, and a rubber stop block is fixedly connected to the inner side of the chassis.

[0016] The above scheme uses a second electric push rod to drive the moving plate through the connecting plate, thereby achieving automatic and precise adjustment of the detection platform position without manual operation, which greatly improves the convenience and efficiency of operation. At the same time, the rubber block can block the heating tube body after the detection is completed. In conjunction with the pulley, the heating tube body falls into the cavity below for collection, which facilitates the collection of the tested heating tube body and improves the practicality of the device.

[0017] Furthermore, an extension frame is fixedly connected to the outside of the chassis, a conveyor belt is installed on the inside of the extension frame, a third electric push rod is fixedly installed on the upper side of the extension frame, and a push block is fixedly connected to the output end of the third electric push rod. The inner curvature of the push block is adapted to the shape of the heating tube body.

[0018] Through the above scheme, the conveyor belt can automatically and continuously transport the heating tube body. The third electric push rod drives the push block to accurately push the heating tube body onto the detection platform, realizing automatic feeding of the heating tube body, reducing manual operation links, effectively improving production efficiency. Moreover, the push block is adapted to the shape of the heating tube body, ensuring a stable and reliable pushing process and preventing the heating tube from shifting or falling during transmission.

[0019] Furthermore, the detection component includes a first electric push rod fixedly connected to the outside of the chassis. The output end of the first electric push rod is fixedly connected to a connecting frame. Three guide sleeves are fixedly connected to the inner side of the connecting frame. The three guide sleeves are arranged in a triangular array. A first slide rod is slidably connected to the inner side of each of the three guide sleeves. A detection block is fixedly installed at the bottom end of each of the three first slide rods. A second spring is fixedly installed on the upper side of each of the three detection blocks, and the other end of the second spring is fixedly connected to the bottom surface of the connecting frame.

[0020] The above scheme uses a first electric push rod to move the connecting frame, bringing the detection block closer to the main electrode of the heating tube. The guide sleeve and the first slide rod ensure the stability and accuracy of the detection block's movement. The elasticity of the second spring allows the detection block to fit tightly against the main electrode of the heating tube, ensuring good detection contact and effectively improving the accuracy and reliability of the detection data.

[0021] Furthermore, two fixed seats are provided above the connecting frame. The outer sides of the two fixed seats are fixedly connected to the outer side of the chassis, and the inner sides of the two fixed seats are slidably connected to a second sliding rod, and the bottom end of the second sliding rod is fixedly connected to the upper surface of the connecting frame.

[0022] Through the above scheme, the fixed seat and the second slide bar are set to further guide and limit the connecting frame, enhance the stability of the connecting frame during movement, thereby ensuring that the detection block can accurately and stably contact the main electrode of the heating tube, further improving the detection accuracy and reducing the detection error.

[0023] Beneficial effects

[0024] This new testing equipment for electric heating tube production, by incorporating an adaptive clamping assembly, allows for flexible adjustment of the clamping position and force on electric heating tube bodies of different specifications, compared to traditional testing equipment with fixed limiting baffles. Simultaneously, the sliding cooperation between the guide rod and the moving block, combined with the elasticity of the first spring, enables the moving block to automatically adjust its position according to the size of the electric heating tube body. Furthermore, the hinged rod and fixed shaft drive the clamping frame to adaptively clamp electric heating tube bodies of different specifications, thus adapting to the problem of electric heating tubes of varying sizes and significantly improving the equipment's versatility. The conveyor belt automatically and continuously transports the electric heating tube bodies, and a third electric push rod drives a pusher block to accurately push the electric heating tube bodies onto the testing platform, achieving automatic feeding of the electric heating tube bodies, reducing manual operation, effectively improving production efficiency, and further enhancing the overall practicality of the testing equipment.

The movable plate 3 is driven to move by the second electric push rod 8 through the connecting plate 9, realizing the automatic and precise adjustment of the position of the detection platform 4 without manual operation, which greatly improves the convenience and efficiency of operation. At the same time, the rubber stop 10 can block the electric heating tube body 6 after the detection is completed. In conjunction with the pulley 508, the electric heating tube body 6 falls into the cavity below for collection, which facilitates the collection of the tested electric heating tube body 6 and improves the practicality of the device.

[0034] Please see Figure 1 and Figure 2 An extension frame 11 is fixedly connected to the outside of the chassis 1. A conveyor belt 12 is installed on the inside of the extension frame 11. A third electric push rod 13 is fixedly installed on the upper side of the extension frame 11. A push block 14 is fixedly connected to the output end of the third electric push rod 13. The inner curvature of the push block 14 matches the shape of the heating tube body 6. The conveyor belt 12 can automatically and continuously transport the heating tube body 6. The third electric push rod 13 drives the push block 14 to accurately push the heating tube body 6 onto the detection platform 4, realizing automatic feeding of the heating tube body 6, reducing manual operation links, effectively improving production efficiency. Moreover, the push block 14 matches the shape of the heating tube body 6, ensuring a stable and reliable pushing process and preventing the heating tube from shifting or falling during transmission.

[0035] Please see Figure 1 , Figure 3 and Figure 4The adaptive clamping assembly 5 includes a bracket 501 fixedly connected to the upper side of the detection platform 4. A guide rod 502 is fixedly connected to the inner side of the bracket 501, and two symmetrical moving blocks 503 are slidably connected to the outer side of the guide rod 502. The sliding cooperation between the guide rod 502 and the moving blocks 503, combined with the elastic action of the first spring 504, allows the moving blocks 503 to automatically adjust their position according to the size of the heating tube body 6. The two moving blocks 503 are fixedly connected to the side that is far apart from each other by the first spring 504. 504 is fixedly connected to the inner side of the bracket 501. The outer sides of the two moving blocks 503 are hinged with hinge rods 505. The bracket 501 is provided with a clamping frame 506. Two fixed shafts 507 are fixedly connected to the upper side of the clamping frame 506. The other ends of the two hinge rods 505 are rotatably connected to the outer side of the fixed shafts 507. The clamping frame 506 is driven by the hinge rods 505 and the fixed shafts 507 to adaptively clamp the heating tube body 6 of different specifications, thereby adapting to the problem of heating tubes of different sizes and significantly improving the versatility of the equipment.

[0036] Please see Figure 1 , Figure 3 and Figure 4 The bracket 501 has a guide groove 510 on its inner side. The outer sides of the two moving blocks 503 are slidably connected to the inner side of the guide groove 510. By setting the guide groove 510 on the inner side of the bracket 501, the moving blocks 503 are precisely limited and guided, effectively preventing the moving blocks 503 from deviating during sliding. This ensures the accuracy and reliability of the clamping frame 506 in clamping the heating tube body 6, providing a stable foundation for subsequent testing. The inner side of the clamping frame 506 is rotatably connected to multiple equally spaced pulleys 508. Each pulley... The material of 508 is rubber. When clamping the heating tube body 6, the rubber pulley 508 can effectively avoid damage to the surface of the heating tube due to the softness of the rubber material. One end of the clamping frame 506 is fixedly connected to a guide rod 509. The guide rod 509 is inclined. When the heating tube body 6 moves, the clamping frame 506 can move to both sides by itself, so as to facilitate the movement of the heating tube body 6 to a suitable position, which significantly improves the convenience and efficiency of the testing operation.

[0037] Please see Figure 1 , Figure 2 and Figure 5The detection component 7 includes a first electric push rod 701 fixedly connected to the outside of the chassis 1. A connecting frame 702 is fixedly connected to the output end of the first electric push rod 701. Three guide sleeves 703 are fixedly connected to the inner side of the connecting frame 702. The three guide sleeves 703 are arranged in a triangular array. A first slide rod 704 is slidably connected to the inner side of each of the three guide sleeves 703. A detection block 705 is fixedly installed at the bottom end of each of the three first slide rods 704. A second spring 706 is fixedly installed on the upper side of each of the three detection blocks 705. The other end of the second spring 706 is fixedly connected to the bottom surface of the connecting frame 702. By setting the first electric push rod 701 to drive the connecting frame 702 to move, the detection block 705 is brought closer to the electrode of the heating tube body 6. The guide sleeves 703 and the first slide rods 704 ensure the stability and accuracy of the movement of the detection block 705. The elasticity of the second spring 706 enables the detection block 705 to fit tightly against the electrode of the heating tube body 6, ensuring good detection contact and effectively improving the accuracy and reliability of the detection data.

[0038] Please see Figure 2 and Figure 5 Two fixed seats 707 are provided above the connecting frame 702. The outer sides of the two fixed seats 707 are fixedly connected to the outer side of the chassis 1. The inner sides of the two fixed seats 707 are slidably connected to the second slide rods 708, and the bottom end of the second slide rods 708 is fixedly connected to the upper surface of the connecting frame 702. The fixed seats 707 and the second slide rods 708 further guide and limit the connecting frame 702, enhance the stability of the connecting frame 702 during movement, and thus ensure that the detection block 705 can accurately and stably contact the electrode of the heating tube body 6, further improving the detection accuracy and reducing the detection error.

[0039] This embodiment of an electric heating tube production testing device, by setting an adaptive clamping component 5, can flexibly adjust the clamping position and force on electric heating tube bodies 6 of different specifications compared with traditional testing devices with fixed limiting baffles. At the same time, the sliding cooperation between the guide rod 502 and the moving block 503, combined with the elastic action of the first spring 504, allows the moving block 503 to automatically adjust its position according to the size of the electric heating tube body 6. The clamping frame 506 is driven by the hinge rod 505 and the fixed shaft 507 to adaptively clamp electric heating tube bodies 6 of different specifications, thereby adapting to the problem of electric heating tubes of different sizes and significantly improving the versatility of the equipment. Meanwhile, the conveyor belt 12 can automatically and continuously transport the electric heating tube body 6, and the third electric push rod 13 drives the push block 14 to accurately push the electric heating tube body 6 onto the testing platform 4, realizing automatic feeding of the electric heating tube body 6, reducing manual operation links, effectively improving production efficiency, and further improving the overall practicality of the testing equipment.

[0040] The working principle of the above embodiment is as follows: First, the heating element body 6 is automatically conveyed by the conveyor belt 12. When the heating element body 6 reaches the designated position, the third electric push rod 13 drives the push block 14 to accurately push it onto the detection platform 4. At this time, the heating element body 6 placed on the detection platform 4 will squeeze the guide rod 509 set on the inclined surface, causing the clamping frame 506 to move to both sides. At this time, the clamping frame 506 drives the hinge rod 505 to rotate through the fixed shaft 507, thereby pushing the moving block 503 to slide in the guide rod 502 and the guide groove 510 and compress the first spring 504. The elastic reaction force of the first spring 504 is used to realize the adaptive clamping of heating element bodies 6 of different specifications. During this process, the pulley 508 ensures that the clamping process is stable and does not damage the surface of the heating element. Then, the detection component 7 starts to work, and the first electric push rod 701 drives the connecting frame 702. The connecting frame 702 moves, and the guide sleeve 703 and the first slide rod 704 drive the detection block 705 to approach the electrode of the heating tube body 6. The second spring 706 keeps the detection block 705 tightly against the electrode. At the same time, the fixed seat 707 and the second slide rod 708 ensure the stable movement of the connecting frame 702 and ensure good detection contact, so as to perform accurate detection. After the detection is completed, the second electric push rod 8 in the housing 1 drives the moving plate 3 to slide in the track groove 2 through the connecting plate 9, which drives the detection platform 4 to move inward to the inside of the housing 1. At this time, the heating tube body 6 stops moving inward under the obstruction of the rubber stop block 10. At the same time, the detection platform 4 moves, and the pulley 508 works to keep the heating tube body 6 stable and prevent it from being damaged. After the detection platform 4 enters the inside of the housing 1, the heating tube body 6 can fall into the cavity inside the housing 1 through the track groove 2 for collection.
