Description

Technical Field

[0001] This application relates to the technical field of testing devices, and in particular to an integrated testing device for a speed reducer commutator. Background Technology

[0002] Currently, the commutator of the speed reducer is a core transmission component in precision machinery such as modern industrial automation equipment, robots, and CNC machine tools. Its key performance indicators, such as torque transmission characteristics, transmission efficiency, temperature rise, vibration and noise, and service life, directly determine the stability and reliability of the entire system.

[0003] Currently, performance testing platforms for speed reducer commutators typically consist of a drive unit, a load unit, a torque sensor, a speed sensor, and tooling fixtures for mounting the test piece. The speed reducer commutator is mounted and fixed on the base of the test bench, with its input end connected to the drive unit and its output end connected to the load unit. During testing, the drive unit simulates the input speed and torque under actual working conditions, while the load unit applies a preset load resistance. The sensors collect and record data such as torque, speed, efficiency, and temperature of the test piece under different working conditions in real time, thereby evaluating whether its performance meets the standards.

[0004] During the test, the reducer itself, the drive motor and the load unit will generate a lot of heat, which will cause the ambient temperature and the temperature of the tested part to rise continuously, the viscosity of the lubricating oil to decrease, and the wear of the gears to intensify, which can easily damage the equipment itself and affect the accuracy of the test results.

[0010] Furthermore, the cooling section includes: Cooling cylinder, filled with coolant; The insulation plate is fixed to the front end of the cooling cylinder and is used to isolate the temperature transfer between the cooling cylinder and the air outlet. The circulation system is used to circulate the coolant in the cold tank; and The regulating assembly is used to deliver the cooling cylinder to the air outlet. The adjusting frame is provided with a cooling cavity for the sliding of the cooling cylinder. The cooling cylinder slides and adapts to the cooling cavity. The cooling cavity is located above the air outlet and is connected to the air outlet. When the adjusting group transports the cooling cylinder to directly above the air outlet, it begins to cool down rapidly.

[0011] Furthermore, the adjustment group: The slider and the cooling chamber are provided with a sliding groove, and the slider slides and the sliding groove are adapted to each other; and The drive unit is used to control the movement of the slider; The buffer group works in conjunction with the phase transition time of the shape memory alloy to control the activation of the rapid cooling operation.

[0012] Furthermore, the buffer group includes: The buffer tank is fixed inside the cooling chamber and filled with a liquid medium. The buffer plate slides and adapts to the buffer box; Springs, multiple of which are provided for connecting the buffer plate and the bottom wall of the buffer box; and A buffer rod, one end of which is fixedly connected to the corresponding side wall of the buffer plate and the other end extends out of the buffer box; The buffer plate is provided with buffer holes, the buffer box is provided with through holes, the buffer rod slides and adapts to the through holes, and one end of the buffer plate extending out of the buffer box is fixedly connected to the slider.

The above-mentioned graded response mechanism can accurately control the test temperature within a reasonable target range, avoid large temperature fluctuations, and provide stable and reliable environmental boundary conditions for performance testing. 3. When the heat conduction of the second heat-conducting component causes the second shape memory alloy wire to undergo a phase change, it can be assumed that the tension of the first and second shape memory alloy wires is the same. However, due to the resistance of the buffer rod, buffer plate, spring, and liquid medium, the cooling cylinder moves to the air outlet position at a slower speed. Therefore, the switching between the two modes of room temperature blowing cooling and air cooling can be achieved. Attached Figure Description

[0017] The technical solutions of this application will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this application. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0018] This application discloses an integrated testing device for a speed reducer commutator. (Refer to...) Figure 1 The system includes a frame 1; a testing mechanism 2 for testing the torque of the reducer commutator; and a cooling mechanism for managing the heat generated during the operation of the testing mechanism 2. In this embodiment, the reducer commutator is mounted and fixed on the frame 1, with its input end connected to a servo motor unit 21 and its output end connected to a magnetic powder brake. During the test, the servo motor simulates the input speed and torque under actual working conditions, while the magnetic powder brake applies a preset load resistance. Sensors collect and record data such as torque, speed, efficiency, and temperature of the reducer commutator under different working conditions to evaluate whether its performance meets the standards. In this embodiment, the cooling mechanism mainly uses airflow to cool the servo motor unit 21 or the magnetic powder brake unit 22. Therefore, this embodiment mainly utilizes the heat conduction of the servo motor unit 21 or the magnetic powder brake unit 22 to achieve different levels of cooling efficiency.

[0019] The cooling mechanism includes: an air-cooling component 3 for multi-stage air cooling of the testing mechanism 2; and a control mechanism for temperature-controlled cooling of the air-cooling component 3. The control mechanism is powered by the phase change of the shape memory alloy, and this power comes from the temperature of the testing mechanism 2. The testing mechanism 2 is a servo motor unit 21 or a magnetic powder brake unit 22. Of course, in actual operation, the control mechanism may need to be isolated to prevent it from being cooled by the wind. The air-cooling component 3 includes: a blower frame 31, which is mounted on the frame 1; a blower section 32 for providing airflow; an airflow regulating section for adjusting the airflow; and a cooling section for accelerating the cooling efficiency. The blower section 32 adopts... In the prior art, the fan and duct adjustment unit is closed when in a vertical position. When cooling is required, the adjustment unit opens, allowing the air blowing unit 32 to work and cool the test mechanism 2 to prevent it from being damaged by high temperature. The adjustment unit faces the test mechanism 2, and the cooling unit and adjustment unit work together to achieve a multi-stage cooling effect. In this embodiment, the adjustment unit blows air and cools the air for conventional cooling. In addition, it solves the physical contradiction of the prior art cooling system requiring additional power supply, relying on sensors and complex electronic control logic, that is, the heat damage test mechanism 2 is transformed into an energy source to drive the cooling system.

[0020] The air regulating unit includes: an air regulating frame 33, which is mounted on the air blowing frame 31 and laid horizontally; multiple louvers 34, which are rotatably connected to the air regulating frame; and a power unit for controlling the multiple louvers 34 to swing simultaneously; the air regulating frame is provided with an air outlet 35, and the louvers 34 are rotatably mounted at the air outlet 35. When the louvers 34 are in a vertical state, they are in a fully open state, and when the louvers 34 overlap each other, they can seal the air outlet 35. The power unit includes: a shape memory alloy wire 36, one end of which is fixed to the bracket; a heat conductor 37, which transfers heat from the testing mechanism 2 to the shape memory alloy wire 36; the shape memory alloy wire 36 transfers heat through the heat conductor 37, which is made of copper with high thermal conductivity, thus facilitating the transfer of heat to the shape memory alloy wire; a power block 38, which is L-shaped and fixedly connected to the other end of the shape memory alloy wire; and a lever 39, which is rotatably mounted on the bracket and has one end abutting against the power block 38. The horizontal section of the power block 38 is fixedly connected to the shape memory alloy wire 36, and its vertical section abuts against the outer side of the corresponding end of the lever 39, i.e., the end of the lever 39 is located in the gap between the vertical and horizontal sections. The shape memory alloy wire 36 is made of iron-nickel shape memory alloy. The phase change temperature of the shape memory alloy is lower than the heating temperature of the testing mechanism 2. When the shape memory alloy begins to undergo a phase change through the heat conductor 37, it begins to shrink. A pull rope 310 is fixedly connected to the other end of a lever 39; a torsion spring 311 is used to connect the lever 39 and the bracket; a rack 312 is slidably mounted on the bracket; a gear 313 is rotatably mounted on the bracket and meshes with the rack 312; the pull rope 310 can be made of nylon rope material as is available in the prior art; the rotation axis of the gear 313 is parallel to the axis of rotation of the lever 39; in the initial state, the louvers 34 are in a closed state, and the torsion spring 311 is also in its original state; and a synchronous transmission group drives multiple louvers 34 to rotate together through the rotation of the gear 313. The synchronous transmission assembly includes multiple synchronous pulleys 3142 and a synchronous belt 3141. The synchronous pulleys 3142 are coaxially arranged with the corresponding louvers 34. The synchronous belt 3141 is sleeved on the multiple synchronous pulleys 3142. The gear 313 is coaxially arranged with any one of the synchronous pulleys 3142, preferably coaxially connected with the synchronous pulley 3142 located at the end. The lever 39 is rotatably connected to the bracket near the power block 38. The pull rope 310 is taut during movement. The other end of the pull rope 310 is fixedly connected to the end of the rack 312. The connection position of the lever 39 is used to expand the deformation of the shape memory alloy wire 36. During the test, the servo motor unit 21 or the magnetic powder brake unit 22 begins to heat up. Under the action of the heat-conducting component 37, the shape memory alloy wire 36 begins to heat up until the temperature exceeds the phase change temperature. At this time, the control power block 38 retracts, and the power block 38 pulls the top of the lever 39 back. At this time, the lever 39 drives the pull rope 310 to move. The pull rope 310 drives the rack 312 to slide. The rack 312 drives the gear 313 to rotate. At this time, under the action of the synchronous pulley 3142 and the synchronous belt 3141, the louver 34 begins to swing until it is completely vertical. At the same time, the blower 32 begins to blow air onto the air outlet 35, thereby achieving the effect of blowing air to cool the servo motor unit 21 or the magnetic powder brake unit 22.

[0021] To further accelerate the cooling rate, the cooling unit includes: a cooling cylinder 40 filled with coolant, which can be water or other liquids; a circulation group 41 for circulating the coolant in the cooling cylinder, which can be achieved using a water pump and water pipes; simultaneously, the liquid inside the cooling cylinder 40 also needs to be circulated to ensure its temperature is below room temperature, using liquid nitrogen or freezing methods, as long as the liquid inside the cooling cylinder 40 is kept at a constant temperature and below room temperature; and a heat insulation plate fixed to the front end of the cooling cylinder 40 to isolate the cooling cylinder 40 from the air outlet 35. The adjusting frame is equipped with a cooling cavity 42 for sliding the cooling cylinder 40. The cooling cylinder 40 slides and adapts to the cooling cavity 42. The cooling cavity 42 is located above and connected to the air outlet 35. The two ends of the cooling cavity 42 are closed and in a horizontal state. The heat insulation plate slides and adapts to the inner cooling cavity. Thus, when the blowing section 32 starts blowing air for cooling, the cooling cylinder 40 will not affect the normal temperature blowing cooling state. The adjusting group is used to transport the cooling cylinder 40 to the position of the air outlet 35. Rapid cooling only begins when the adjusting group transports the cooling cylinder 40 directly above the air outlet 35, at which point the second cooling state will begin. By setting up an air conditioning section driven by shape memory alloy wire 36 to open louvers 34 and a cooling section driven by a regulating group to open cooling cylinder 40, two-stage cooling is achieved. Under normal heating conditions, only louvers 34 are opened for gentle airflow regulation; only under extreme conditions where the temperature continues to exceed the limit is the cooling cylinder 40 activated for rapid cooling. This graded response mechanism can accurately control the test temperature within a reasonable target range, avoiding large temperature fluctuations and providing stable and reliable environmental boundary conditions for performance testing.

[0022] The system includes an adjustment group: a slider 43, a cooling chamber 42 with a groove and slider 43 sliding and adapting to the groove, one end of slider 43 being inside the cooling cylinder 40 and the other end outside the cooling chamber 42; a drive group for controlling the movement of slider 43; and a buffer group that works in conjunction with the phase transformation time of the shape memory alloy to control the activation of the rapid cooling operation. Slider 43 controls the operation of the buffer group, which controls and slows down the movement speed of the cooling cylinder 40, and controls the movement of the buffer group according to the heating time of the test mechanism 2. The buffer group introduces a mechanical time delay for the activation of the rapid cooling state of the cooling cylinder 40. This design can effectively filter out short-lived, non-continuous temperature spikes during the test, ensuring that powerful cooling is only activated when the temperature continuously exceeds the limit and a dangerous condition is confirmed. This avoids frequent system start-ups and shutdowns and excessive intervention in the test environment caused by instantaneous fluctuations, making the cooling strategy more intelligent, the response more precise and composed, and effectively protecting the safety of the test piece and the test equipment.

[0023] The buffer assembly includes: a buffer box 44, fixed inside the cooling chamber 42 and filled with a liquid medium buffer plate 45, which slides within the buffer box 44; multiple springs 46 for connecting the buffer plate 45 and the bottom wall of the buffer box 44; and a buffer rod 47, one end of which is fixedly connected to the corresponding side wall of the buffer plate 45 and the other end of which extends out of the buffer box 44; the buffer plate 45 is provided with a buffer hole 48, the buffer box 44 is provided with a perforation, the buffer rod 47 slides within the perforation, and the end of the buffer plate 45 extending out of the buffer box 44 is fixedly connected to a slider 43. For fixed connection, the liquid medium can be water or other compressible media. In the initial state, i.e., when cooled at room temperature, the spring 46 is in a free deformation state, and the buffer rod 47 is in a sealed sliding state with the through hole. The sealed sliding is achieved by using a sealing ring or other structure. When the buffer rod 47 is pulled, the liquid medium passes through the buffer hole 48 to the other side. During this process, the elastic force of the spring 46 and the resistance of the liquid medium reduce the movement speed of the buffer rod 47, thereby achieving separation from the conventional air cooling stage.

[0024] The drive assembly includes: a drive rod 49, rotatably connected to the bracket and positioned away from the slider 43; a drive rope 410, one end of which is fixedly connected to the drive rod 49 and the other end of which is fixedly connected to the slider 43; a reset component 411, used to reset the drive rod 49; the reset component 411 is also controlled by a torsion spring 311; a memory alloy wire 412, fixed to the bracket; a drive block 413, fixedly connected to the memory alloy wire 412 and set in a concave shape; and a heat-conducting component 414, used to conduct heat from the test mechanism 2 to the memory alloy wire 412; after the memory alloy wire 412 is heated by the heat-conducting component 414 and exceeds the phase change temperature, it begins to control the movement of the slider 43. In this embodiment, the control effect of the drive assembly is the same as that of the memory alloy wire 412. The drive rod 49 is also used to increase the phase change stroke of the memory alloy wire 412. In addition, the drive block 413 follows the movement of the memory alloy wire 412, and under the action of the drive rope 410 and the drive rod 49, the cooling cylinder 40 is controlled to move towards the air outlet 35.

[0025] Of course, shape memory alloy wire 36 and shape memory alloy wire 412 can conduct heat to the servo motor unit 21 or the magnetic powder brake unit 22 respectively according to their position. The phase change temperature of shape memory alloy wire 412 is slightly higher than that of shape memory alloy wire 36. Thus, although the temperature of the testing mechanism 2 reaches the temperature at which the first alloy wire begins to undergo phase change, it does not cause shape memory alloy wire 412 to begin phase change. It should be noted here that neither shape memory alloy wire 36 nor shape memory alloy wire 412 should be affected by wind. When the heat conduction of the heat conduction component 414 causes shape memory alloy wire 412 to begin to undergo phase change, it can be considered that the tension converted by shape memory alloy wire 36 and shape memory alloy wire 412 is the same. However, under the action of the buffer rod 47, the buffer plate 45, the spring 46, and the resistance of the liquid medium, the speed at which the cooling cylinder 40 moves to the air outlet 35 is relatively slow. Therefore, the switching between the two modes of room temperature blowing cooling and air cooling can be realized.

[0026] The implementation principle of the integrated detection device for speed reducer commutator in this application embodiment is as follows: the adjustment part is for blowing air and blowing cold air to carry out conventional cooling. In addition, it solves the physical contradiction that the cooling system in the prior art needs additional power supply, relies on sensors and complex electronic control logic. That is, the heat damage testing mechanism 2 is transformed into the energy source to drive the cooling system. By setting up an air conditioning section driven by shape memory alloy wire 36 to open louvers 34 and a cooling section driven by a cooling cylinder 40, two-stage cooling is achieved. Under normal heating conditions, only louvers 34 are opened for gentle airflow regulation; only under extreme conditions where the temperature continues to exceed the limit is the cooling cylinder 40 activated for rapid cooling. This graded response mechanism can accurately control the test temperature within a reasonable target range, avoiding large temperature fluctuations and providing stable and reliable environmental boundary conditions for performance testing. Under the action of the heat-conducting component 37, the shape memory alloy wire 36 begins to heat up until the temperature exceeds the phase change temperature. At this time, the control power block 38 contracts, and the power block 38 pulls the top of the lever 39 back. At this time, the lever 39 drives the pull rope 310 to move, the pull rope 310 drives the rack 312 to slide, and the rack 312 drives the gear 313 to rotate. At this time, under the action of the synchronous pulley 3142 and the synchronous belt 3141, the louver 34 begins to swing until it is completely vertical. At the same time, the blower 32 begins to blow air onto the air outlet 35, thereby achieving the effect of blowing air to cool the servo motor unit 21 or the magnetic powder brake unit 22. When the heat is conducted by the heat-conducting component 414, the shape memory alloy wire 412 begins to undergo a phase change. It can be assumed that the tension converted by the shape memory alloy wire 36 and the shape memory alloy wire 412 is the same. However, under the action of the buffer rod 47, the buffer plate 45, the spring 46, and the resistance of the liquid medium, the speed at which the cooling cylinder 40 moves to the air outlet 35 is relatively slow. Therefore, the switching between the two modes of room temperature blowing cooling and air cooling can be realized.
