Description

Technical Field

[0001] The present invention belongs to the field of testing, and specifically discloses a testing device for the production of air-source heat pump heaters. Background Art

[0002] An air-source heat pump heater is an innovative heating device that combines modern technology and environmental protection concepts. Based on the reverse Carnot cycle, it obtains heat energy from the air for heating. During operation, a small amount of electrical energy drives the compressor, and the working medium circulates through various components, successively completing heat absorption and evaporation, compression and temperature rise, heat release and condensation, and throttling and pressure reduction to achieve heat transfer and provide heating for the indoor environment. Compared with traditional gas boiler heating and electric heating, the air-source heat pump heater has high energy efficiency. The internal temperature sensor is crucial. It can sense the temperature changes of the device and the environment, feedback to the control system to achieve intelligent regulation, maintain a comfortable indoor temperature, avoid energy waste, and can also monitor the temperature of key components, alarm in case of anomalies and initiate protection measures to ensure the safe and stable operation of the device and extend its service life.

[0003] It is very necessary to conduct airtightness detection on the internal temperature sensor of the air-source heat pump heater. On the one hand, the circulation of the working medium inside the device makes the environment where the temperature sensor is located complex and the pressure variable. Poor airtightness is likely to allow external air or water vapor to enter, damaging its internal structure and components. On the other hand, this is related to the accuracy of temperature measurement. Impurity gases interfere with heat conduction, and data deviation will mislead the control system and affect the adjustment of heating power.

[0004] In the prior art, when conducting airtightness detection on the temperature sensor, it is necessary for workers to use special tools to fix the temperature sensor, and the installation and disassembly operations are relatively cumbersome, consuming too much manpower and time. Summary of the Invention

[0005] In view of this, the purpose of the present invention is to propose a testing device for the production of air-source heat pump heaters to solve the problem that in the prior art, when conducting airtightness detection on the temperature sensor, it is necessary for workers to use special tools to fix the temperature sensor, and the installation and disassembly operations are relatively cumbersome, consuming too much manpower and time.

A first stop block and a second stop block are respectively installed on both sides of the turntable inside the activity groove. The first stop block and the second stop block respectively correspond to the convex platform on the side and the convex platform on the bottom.

[0010] In the above technical solution, preferably, the clamping mechanism includes a positioning table, which is installed above the connecting plate by bolts. A first semi-circular groove is formed on the upper surface of the positioning table, and a first sliding groove is formed on the bottom surface of the first semi-circular groove. A sliding block is slidably installed inside the first sliding groove. A limiting groove is formed on the surface of the sliding block, and a first clamping plate is fixedly installed at the front end of the sliding block. A second clamping plate is movably installed inside the limiting groove. The first clamping plate and the second clamping plate are parallel and corresponding, and semi-circular clamping grooves are formed on the surfaces of the first clamping plate and the second clamping plate. Two side grooves are symmetrically formed on both sides of the first semi-circular groove. First side plates are provided at both ends of the first clamping plate, and second side plates are provided at both ends of the second clamping plate. The first side plates and the second side plates movably penetrate through the side grooves.

[0011] In the above technical solution, preferably, a T-shaped rod penetrates through the end of the second side plate. The larger-diameter end of the T-shaped rod is movably located between the first side plate and the second side plate. A first tension spring is installed on the end face of the first side plate close to the second side plate, and the end of the first tension spring is connected to the T-shaped rod. A pushing block is fixedly installed at the other end of the T-shaped rod.

[0012] In the above technical solution, preferably, a placement platform is installed at the top of the movable groove, and pressing plates are installed on both sides of the placement platform.

[0013] In the above technical solution, preferably, the matching mechanism includes a cross bar, which is installed in the detection cavity by bolts. A second semi-circular groove is formed in the middle of the cross bar, and a second sliding groove is formed on the inner wall of the second semi-circular groove. The bottom of the second sliding groove penetrates through the cross bar. A matching plate is slidably arranged inside the second sliding groove.

[0014] In the above technical solution, preferably, an observation port is formed at the front end of the box body, and glass is installed on the surface of the observation port.

[0015] Compared with the prior art, the present invention has the following beneficial effects: The flipping mechanism flips the clamping mechanism into the interior of the detection chamber, making the clamping mechanism perpendicular to the box body and directly below the pressing head. This precise positional relationship enables the pressing head to accurately press the temperature sensor during subsequent detection. During the detection process, the stable position fixation can effectively prevent the temperature sensor from being affected by shaking and thus ensure the accuracy of the detection results. At the same time, the cooperation plate of the cooperation mechanism corresponds to the clamping mechanism, forming a bilateral clamping and positioning effect. The precise position determined by the flipping mechanism provides a prerequisite for this bilateral clamping and positioning, further enhancing the stability of the temperature sensor during the detection process and effectively guaranteeing the smooth progress of the detection work and the reliability of the detection results; The flipping mechanism has the turntable as the core component. Driven by the stepping motor, the turntable rotates smoothly in the movable groove through the rotating shaft. When installing the temperature sensor, the turntable rotates to drive the curved bracket, and then the positioning table connected to the curved bracket flips above the box body. At this time, the extrusion plates on both sides of the placement platform play a role, extruding the push block, prompting the T-shaped rod to drive the second clamping plate away from the first clamping plate, increasing the distance between the first clamping plate and the second clamping plate. This design allows the staff to easily place the temperature sensor in the first semi-circular groove. Subsequently, after the flipping mechanism drives the turntable to rotate in the opposite direction, under the action of the first tension spring, the second clamping plate quickly approaches the first clamping plate, completing the firm clamping and installation of the temperature sensor. After the detection is completed, by leveraging this movement process of the flipping mechanism again, the temperature sensor can be conveniently retrieved, greatly improving the operation convenience and saving labor and time costs; Under the action of the clamping mechanism, the pulling force of the first tension spring can bring the second clamping plate closer to the first clamping plate, making the semi-circular clamping grooves on both of them closely fit the temperature sensor, generating a stable and strong clamping force to firmly fix the temperature sensor, preventing it from shaking, displacing, or falling off during the detection and ensuring the stability and accuracy of the detection data.

[0019] In the following description, many specific details are set forth in order to fully understand the present invention. However, the present invention may be implemented in other ways different from those described herein. Therefore, the present invention is not limited by the limitations of the specific embodiments disclosed below.

[0020] Such as Figures 1 - 10A testing device for the production of an air source heat pump heating machine shown in the figure includes a box body 1. A detection cavity 9 is formed inside the box body 1. An activity groove 13 is formed inside the box body 1 and on one side of the detection cavity 9. A turning mechanism 11 is arranged inside the activity groove 13. A clamping mechanism 12 is arranged above the activity groove 13. A temperature sensor 40 is installed inside the clamping mechanism 12. The turning mechanism 11 is used to turn the clamping mechanism 12. The clamping mechanism 12 is used to clamp and position the temperature sensor 40. A matching mechanism 31 is arranged inside the detection cavity 9. The matching mechanism 31 can further ensure the stability of the temperature sensor 40 during the detection process. The turning mechanism 11 drives the positioning table to turn, which is convenient for installing and recycling the temperature sensor 40, saving manpower and time. Through the mutual cooperation of the turning mechanism 11 and the clamping mechanism 12, the pressing head 7 can accurately press the temperature sensor 40. And through the matching mechanism 31, bilateral clamping of the temperature sensor 40 is realized, avoiding shaking during the detection process and ensuring the accuracy and reliability of the detection result. A testing mechanism is arranged on the top of the box body. The testing mechanism includes a pressing head 7 and an air delivery pipe 8. The testing mechanism can press the bottom of the temperature sensor 40 into the detection cavity 9. Gas is delivered to the pressing head 7 through the air delivery pipe 8. After the gas is input into the temperature sensor 40, it can be observed whether there are bubbles in the liquid inside the detection cavity 9 to complete the detection of the temperature sensor 40; Among them, the temperature sensor 40 is the component to be detected. Under the action of the turning mechanism 11 and the clamping mechanism 12, it can ensure the accuracy, efficiency and safety during the testing process, and finally provide a reliable basis for the quality control of the air source heat pump heating machine.

[0021] A support platform 2 is fixedly installed on the back of the box body 1. A cylinder box 4 is installed above the support platform 2. A cylinder is arranged inside the cylinder box 4. The output end of the cylinder is installed with a telescopic column 5. The telescopic column 5 penetrates through the top of the cylinder box 4. The top end of the telescopic column 5 is installed with a top plate 6. The bottom of the front end of the top plate 6 is installed and connected with the pressing head 7. The pressing head 7 corresponds to the center of the detection cavity 9. A sealing groove is formed at the bottom of the pressing head 7. The cylinder inside the cylinder box 4 drives the telescopic column 5, so that the top plate 6 drives the pressing head 7 to be accurately located at the center of the detection cavity 9, so as to press the temperature sensor 40. The sealing groove can wrap the top of the temperature sensor 40. The top of the temperature sensor 40 abuts against the inner wall of the sealing groove, ensuring that the position of the component to be detected is fixed during the testing process and avoiding affecting the accuracy of the testing result due to the shaking of the component. The top of the front end of the top plate 6 is installed and connected with the air delivery pipe 8. The air delivery pipe 8 is connected to the pressing head 7. Gas can be delivered to the pressing head 7 through the air delivery pipe 8 according to the testing requirements. A guide rod 3 is installed behind the support platform 2. The guide rod 3 penetrates through the top plate 6, providing a stable guiding function for the up and down movement of the top plate 6.

[0022] The flipping mechanism 11 includes a turntable 14. The turntable 14 is rotationally installed inside the movable slot 13 through a rotating shaft. The structural design is simple and clear. This simple installation method makes the rotation of the turntable 14 smoother, reduces friction and energy loss caused by complex structures, and improves the operating efficiency of the entire flipping mechanism. A stepper motor is installed inside the box body 1. The output end of the stepper motor is connected to the rotating shaft. A curved bracket 15 is installed on the surface of the turntable 14. The curved bracket 15 is set in a hook shape. The other end of the curved bracket 15 is fixedly installed with a connecting plate 16. The top of the connecting plate 16 is connected to the clamping mechanism 12. By driving the turntable 14 to rotate through the stepper motor, the turntable 14 will drive the curved bracket 15 to rotate at the same time. Thus, the end of the curved bracket 15 will rotate into the detection cavity 9. At this time, the clamping mechanism 12 is perpendicular to the box body 1, and the clamping mechanism 12 is directly below the pressing head 7.

[0023] Protrusions are installed on both the side and the bottom surface of the turntable 14. A first stopper 17 and a second stopper 18 are respectively installed on both sides of the turntable 14 inside the movable slot 13. The first stopper 17 and the second stopper 18 correspond to the protrusions on the side surface and the bottom surface respectively. The first stopper 17 and the second stopper 18 corresponding to the protrusions on the side and the bottom surface of the turntable 14 can provide precise limits for the rotation of the turntable 14. When the stepper motor drives the turntable 14 to rotate, the protrusions will contact it at specific positions, thereby accurately limiting the rotation angle of the turntable 14, ensuring that the clamping mechanism 12 can reach the predetermined position every time it flips, and further guaranteeing the positioning accuracy of the temperature sensor 40 in the detection cavity 9, making the measurement results more accurate and reliable.

[0024] The snap-in mechanism 12 includes a positioning table. The positioning table is installed above the connecting plate 16 by bolts, providing a stable installation foundation for the temperature sensor 40. A first semi-circular groove 19 is formed on the upper surface of the positioning table, and a first sliding groove 20 is formed on the bottom surface of the first semi-circular groove 19. A sliding block 21 is slidably installed inside the first sliding groove 20. A limiting groove 22 is formed on the surface of the sliding block 21. A first clamping plate 23 is fixedly installed at the front end of the sliding block 21. A second clamping plate 24 is movably installed inside the limiting groove 22. The first clamping plate 23 and the second clamping plate 24 are parallel and corresponding, and semi-circular clamping grooves are formed on the surfaces of the first clamping plate 23 and the second clamping plate 24. Two side grooves 25 are symmetrically formed on both sides of the first semi-circular groove 19. First side plates 26 are arranged at both ends of the first clamping plate 23, and second side plates 27 are arranged at both ends of the second clamping plate 24. The first side plates 26 and the second side plates 27 movably penetrate through the side grooves 25. The cooperation of the first sliding groove 20 and the sliding block 21 enables the first clamping plate 23 to slide flexibly. And under the action of the second clamping plate 24, the semi-circular clamping grooves on the first clamping plate 23 and the second clamping plate 24 can closely fit the temperature sensor, providing a stable clamping force. The first side plates 26 and the second side plates 27 movably penetrate through the side grooves 25. This structure restricts the movement of the first clamping plate 23 and the second clamping plate 24, further preventing the temperature sensor 40 from loosening or falling off during the detection process, ensuring the stability and accuracy of the detection data.

[0025] A T-shaped rod 29 is arranged through the end of the second side plate 27. The larger-diameter end of the T-shaped rod 29 is movably located between the first side plate 26 and the second side plate 27. A first tension spring 28 is installed on the end face of the first side plate 26 close to the second side plate 27. The end of the first tension spring 28 is connected to the T-shaped rod 29. A pushing block 30 is fixedly installed at the other end of the T-shaped rod 29. The setting of the first tension spring 28 makes the second clamping plate 24 move closer to the first clamping plate 23. When clamping the temperature sensor 40, the pulling force generated by the first tension spring 28 can firmly fix the temperature sensor 40 between the second clamping plate 24 and the first clamping plate 23, preventing it from shaking or displacing during the detection process, thereby improving the accuracy of the detection.

[0026] A placement platform 39 is installed at the top of the movable groove 13. Extrusion plates 38 are installed on both sides of the placement platform 39. When the stepping motor drives the turntable 14 to rotate, the turntable 14 will simultaneously drive the curved bracket 15 to rotate. After the positioning table is flipped above the box body 1, the end of the extrusion plate 38 will cause extrusion on the pushing block 30. Thus, the pushing block 30 drives the T-shaped rod 29 to move in the other direction, and the second clamping plate 24 will gradually move away from the first clamping plate 23 at the same time. At this time, the distance between the first clamping plate 23 and the second clamping plate 24 is lengthened, and the staff can conveniently recycle and install the temperature sensor 40.

[0027] The cooperating mechanism 31 includes a cross bar 32 which is installed in the detection cavity 9 by bolts. A second semi-circular groove 33 is formed in the middle of the cross bar 32. A second sliding groove 34 is formed in the inner wall of the second semi-circular groove 33. The bottom of the second sliding groove 34 penetrates through the cross bar 32. A cooperating plate 37 is slidably arranged inside the second sliding groove 34. The cooperating plate 37 corresponds to the first clamping plate 23 and the second clamping plate 24. A smooth rod 35 is installed inside the second sliding groove 34. The bottom of the smooth rod 35 protrudes from the second sliding groove 34. The end of the cooperating plate 37 is slidably installed on the surface of the smooth rod 35, which plays a guiding role for the movement of the cooperating plate 37 and ensures the stability of the cooperating plate 37 during movement. A second tension spring 36 is installed inside the second sliding groove 34. The bottom end of the second tension spring 36 is connected to the cooperating plate 37. A semi-circular cooperating groove corresponding to the semi-circular clamping groove is formed on the surface of the cooperating plate 37. The cooperating plate 37 in the cooperating mechanism 31 corresponds to the first clamping plate 23 and the second clamping plate 24 of the clamping mechanism 12, and a semi-circular cooperating groove corresponding to the semi-circular clamping groove is formed on the surface of the cooperating plate 37. After the temperature sensor 40 is clamped by the clamping mechanism 12, the semi-circular cooperating groove of the cooperating plate 37 can support and cooperate with the temperature sensor 40 from the other side, forming a bilateral clamping and positioning effect, greatly improving the stability of the temperature sensor 40 during the detection process, reducing the possibility of its shaking or displacement, and thus ensuring the accuracy of the detection of the temperature sensor 40.

[0028] An observation port 10 is formed at the front end of the box body 1. A glass is installed on the surface of the observation port 10, through which it can be clearly seen whether the installation position of the temperature sensor 40 is correct, and the state of the temperature sensor 40 during the detection process can be observed.

[0029] Working principle: First, the stepping motor drives the turntable 14 to rotate, causing the curved bracket 15 to rotate and the positioning table to flip above the box body 1. At this time, the ends of the pressing plates 38 on both sides of the placing platform 39 squeeze the pushing block 30, and the pushing block 30 drives the T-shaped rod 29 to move, causing the second clamping plate 24 to move away from the first clamping plate 23, and the distance between the first clamping plate 23 and the second clamping plate 24 is elongated. The staff places the temperature sensor 40 in the first semi-circular groove 19 between the first clamping plate 23 and the second clamping plate 24, and then starts the stepping motor again to drive the turntable 14 to rotate. The turntable 14 drives the curved bracket 15 to rotate, causing the end of the curved bracket 15 to rotate into the detection cavity 9. During this process, under the action of the first tension spring 28, the second clamping plate 24 moves closer to the first clamping plate 23, and the semi-circular clamping grooves on the first clamping plate 23 and the second clamping plate 24 closely fit the temperature sensor 40, completing the installation of the temperature sensor 40. After the flipping is completed, the clamping mechanism 12 is perpendicular to the box body 1 and is directly below the pressing head 7. During this process, the convex platforms on the side and bottom of the turntable 14 will contact the first stop block 17 and the second stop block 18 at specific positions, limiting the rotation angle of the turntable 14 to ensure that the clamping mechanism 12 reaches the predetermined position. Start the cylinder in the cylinder box 4, and the cylinder drives the telescopic column 5 to move upward. The telescopic column 5 drives the top plate 6 to rise, and the pressing head 7 at the front end of the top plate 6 precisely presses the temperature sensor 40 located at the center of the detection cavity 9. The sealing groove can wrap the top of the temperature sensor 40, and the top of the temperature sensor 40 abuts against the inner wall of the sealing groove. During its downward pressing process, it can drive the first clamping plate 23 and the second clamping plate 24 to displace downward, so that the bottom of the temperature sensor 40 is immersed in the liquid, ensuring that the position of the temperature sensor 40 is fixed during the test. Then, it is connected to the pressing head 7 through the air delivery pipe 8, and gas can be delivered to the pressing head 7 according to the test requirements. After the gas is input into the temperature sensor 40, observe whether there are bubbles in the liquid inside the detection cavity 9. The cooperation plate 37 in the cooperation mechanism 31 corresponds to the first clamping plate 23 and the second clamping plate 24 of the clamping mechanism 12, and semi-circular cooperation grooves corresponding to the semi-circular clamping grooves are provided on the surface of the cooperation plate 37. When the temperature sensor 40 moves into the detection cavity 9, the semi-circular cooperation grooves of the cooperation plate 37 can support and cooperate with the temperature sensor 40 from the other side, forming a bilateral clamping and positioning effect, improving the stability of the temperature sensor 40 during the detection process. At the same time, since the end of the cooperation plate 37 is slidably installed on the surface of the optical rod 35, during the process of the first clamping plate 23 and the second clamping plate 24 being pressed down by the pressing head 7, the cooperation plate 37 will move downward synchronously. Finally, the staff can observe through the glass on the surface of the observation port 10 at the front end of the box body 1 whether the installation position of the temperature sensor 40 is correct and its state during the detection process. After the detection is completed, start the stepping motor again to drive the turntable 14 to rotate, causing the curved bracket 15 to rotate, and the positioning table to flip above the box body 1. The ends of the pressing plates 38 on both sides of the placing platform 39 squeeze the pushing block 30 again.Move the second splint 24 away from the first splint 23, increasing the distance between the first splint 23 and the second splint 24, so that the staff can conveniently retrieve the temperature sensor 40.
