Description

Technical Field

[0001] This invention relates to the technical field of motor testing, and in particular to a tensile and torsional force anti-interference testing device. Background Technology

[0002] In recent years, with the rapid development of the drone market, the industry scale has gradually expanded, and application scenarios have gradually shifted from consumer-grade drones to industrial-grade drones. The economic phenomenon of "low-altitude fever" has become increasingly apparent. Heavy-load application drones are urgently needed in fields such as geographic surveying, agricultural and forestry plant protection, patrol and inspection, emergency rescue and disaster relief, and material delivery. Solving the payload problem will be the key to their rapid development. For heavy-load application drones, a test platform is needed that is multifunctional, adaptable to different scenarios, accurate in measurement, highly resistant to interference, and able to simulate real stress conditions. This platform can accurately measure and evaluate motor tension, torque, speed, current, voltage, temperature, airspeed, and motor efficiency to simulate the real-world conditions of the motor as closely as possible.

[0003] For example, Chinese patent document CN116593055A discloses a coaxial testing device for the tension and torque of a motor, which includes a test base, a tension testing component, and a torque testing component. A central shaft is rotatably arranged inside the test base, and a material tray for fixing the motor is arranged on the top of the central shaft. The tension testing component includes a tension sensor and a rotating component. The rotating component is rotatably arranged on the central shaft. The tension sensor is arranged on the test base and is coaxial with the central shaft. The test end of the tension sensor is connected to the rotating component. The tension sensor is used to detect the axial force of the central shaft. The torque testing component includes a torque sensor, a torsion ring, and a pin. The torque sensor is arranged on the test base and is coaxial with the central shaft. The torsion ring is arranged on the test end of the torque sensor. The pin is arranged on the central shaft and is engaged with the torsion ring. When the central shaft is rotated, the pin drives the torsion ring to rotate, thereby allowing the torque sensor to detect the torque of the central shaft. Furthermore, linear bearings and rotary bearings are installed inside the test fixture, and then the central shaft is installed inside the linear bearings and rotary bearings, causing the central shaft to rotate relative to the test fixture. Thus, the motor is mounted on the material carrier. After the motor starts, it applies axial tension and torque to the central shaft. The axial tension is transmitted to the tension sensor for detection through a rotating component, while the torque is applied to the torsion ring through a pin, thereby causing the torque sensor to detect the torque.

[0004] However, existing testing devices have the following problems in practical use: For high-load motors, such as those used in heavy-duty UAVs with a load of 200 kg and a torque of 100 N·m, the central shaft vibrates violently due to the larger up-and-down swing amplitude of the motor's blades compared to ordinary motors. This vibration cannot be eliminated by the existing rotating bearings, and after a period of use, severe wear occurs between the rotating bearings and the central shaft, requiring frequent replacement of the central shaft, wasting testing personnel's time, and increasing material and labor costs. Furthermore, in existing testing devices, the tension sensor and the central shaft are always connected via a rotating component, causing a discrepancy between the tension measured by the sensor and the actual value. Therefore, to solve the above problems, the tension and torque anti-interference testing device of this application is proposed. Summary of the Invention

[0005] The purpose of this invention is to overcome the shortcomings of the prior art and provide a tensile and torsion interference resistance testing device that can effectively resist vibration and improve the reliability of tensile and torsion tests.

[0006] The objective of this invention is achieved through the following technical solution:

[0007] A tensile and torsional interference resistance testing device includes:

[0008] A support assembly, comprising a sleeve, a linear bearing, a drive shaft, and a material carrier plate, wherein the linear bearing is disposed within the sleeve, the drive shaft passes through the linear bearing, and the material carrier plate is disposed on top of the linear bearing;

[0009] A tensile testing assembly includes a tensile sensor, a transmission block, a threaded sleeve, and a planar bearing. The tensile sensor is disposed within the sleeve and located below the linear bearing. A transmission shaft passes through the tensile sensor. The transmission block is disposed on the test end of the tensile sensor. The threaded sleeve is disposed on the transmission shaft. The planar bearing is disposed on the side of the threaded sleeve near the transmission block. The transmission shaft is used to drive the planar bearing to abut against or move away from the transmission block.

[0010] A torque testing assembly includes a torque sensor, a drive pin, and two unloading bearings. The torque sensor is disposed within the sleeve and located below the drive shaft. The drive pin is radially disposed on the end of the drive shaft near the torque sensor. The two unloading bearings are rotatably disposed at both ends of the drive pin and are located within the test end of the torque sensor. The drive shaft is used to drive the unloading bearings to contact or move away from the torque sensor.

[0011] Optionally, the side of the transmission block near the planar bearing has a smooth structure.

[0012] Optionally, the planar bearing includes a planar washer and a plurality of balls. The planar washer is disposed on the side of the threaded sleeve near the transmission block, and each ball is rotatably disposed on the planar washer.

[0013] Optionally, an annular groove is provided on the side of the threaded sleeve near the transmission block, and each of the balls is located in the annular groove.

[0014] Optionally, the sleeve has an internal thread, and the outer wall of the drive shaft has an external thread, with the internal thread engaging with the external thread.

[0015] Optionally, the tensile testing assembly further includes a bushing disposed on the drive shaft and abutting against the threaded sleeve.

[0016] Optionally, the torque testing assembly further includes a positioning pin, which is radially disposed on the drive shaft. The drive shaft is used to drive the positioning pin and the drive pin to rotate synchronously. When the unloading bearing abuts against the test end of the torque sensor, the positioning pin separates from the sleeve. When the positioning pin abuts against the sleeve, the drive pin separates from the test end of the torque sensor.

[0017] Optionally, the sleeve includes a fixed base and a fixed sleeve, the linear bearing is disposed in the fixed base, the tension sensor is disposed in the fixed base, the fixed sleeve is disposed at the bottom of the fixed base, and the torque sensor is disposed in the fixed sleeve.

[0018] Optionally, a clearance groove is provided on the inner side wall of the fixing seat, and the end of the positioning pin is located in the clearance groove.

[0019] Optionally, the tensile testing assembly further includes a silicone sheet, which is sleeved on the drive shaft and used to abut against the tensile sensor.

[0020] Compared with the prior art, the present invention has at least the following advantages:

[0021] 1. By fixing a linear bearing of sufficient length in the housing and then fitting the drive shaft through the linear bearing, the use of only the linear bearing to support the drive shaft is reduced, thus reducing the use of transmission parts. When testing a high-load motor, it can effectively resist the vibration generated by the motor.

[0022] 2. During motor testing, the drive shaft rotates under the torque of the motor and rises under the tension. For the tension sensor, the torque of the drive shaft is not transmitted to the transmission block due to the action of the plane bearing, allowing the tension sensor to detect only the tension of the drive shaft. For the torque sensor, the stress-relieving bearings at both ends of the transmission pin prevent the tension from acting on the torque sensor, ensuring that the torque sensor only detects the torque of the drive shaft. Therefore, the accuracy of motor torque and tension testing is improved, and mutual interference between torque and tension is avoided during the testing process. Attached Figure Description

Detailed Implementation

[0032] To facilitate understanding of the present invention, a more comprehensive description will be given below with reference to the accompanying drawings. The drawings illustrate preferred embodiments of the invention.

[0033] like Figures 1 to 5 As shown, a tensile and torsional interference resistance testing device 10 includes a support assembly 100, a tensile testing assembly 200, and a torsional testing assembly 300. The support assembly 100 includes a sleeve 110, a linear bearing 120, a drive shaft 130, and a material carrier plate 140. The linear bearing 120 is disposed in the sleeve 110, the drive shaft 130 passes through the linear bearing 120, and the material carrier plate 140 is disposed on the top of the linear bearing 120.

[0034] It should be noted that a vertically oriented mounting hole is provided in the sleeve 110, into which the linear bearing 120 is inserted and installed. For example, to improve the structural strength between the linear bearing 120 and the sleeve 110 and to avoid gaps between them, adhesive is applied to the inner wall of the mounting hole, allowing the linear bearing 120 to be inserted and bonded in place. Furthermore, the drive shaft 130 fits through the linear bearing 120. For example, to reduce friction between the drive shaft 130 and the linear bearing 120, resulting in less vibration when the drive shaft 130 rotates, grease is applied to the contact area between the drive shaft 130 and the linear bearing 120. Furthermore, the carrier plate 140 is bolted to the top of the drive shaft 130. Thus, the motor to be tested is fixedly mounted on the carrier plate 140. When the motor is started for testing, it applies torque and lifting force (tension) to the drive shaft 130. In order to accurately test the torque and tension generated by the motor, a tension testing component 200 and a torque testing component 300 are installed in the housing 110.

[0035] like Figures 1 to 5As shown, the tensile testing assembly 200 includes a tensile sensor 210, a transmission block 220, a threaded sleeve 230, and a plane bearing 240. The tensile sensor 210 is disposed inside the sleeve 110 and is located below the linear bearing 120. The transmission shaft 130 passes through the tensile sensor 210. The transmission block 220 is disposed on the test end of the tensile sensor 210. The threaded sleeve 230 is disposed on the transmission shaft 130. The plane bearing 240 is disposed on the side of the threaded sleeve 230 near the transmission block 220. The transmission shaft 130 is used to drive the plane bearing 240 to abut against or move away from the transmission block 220.

[0036] It should be noted that the tension sensor 210 is installed inside the sleeve 110, with the tension sensor 210 located below the linear bearing 120, and the drive shaft 130 passing through the middle of the tension sensor 210. In the natural state (when the motor is not running for testing), the drive shaft 130 and the test end of the tension sensor 210 are in non-contact. The drive block 220 is installed on the test end of the tension sensor 210, and the drive block 220 is oriented downwards. The threaded sleeve 230 is installed on the drive shaft 130, and the flat bearing 240 is installed on the side of the threaded sleeve 230 closest to the drive block 220, and the flat bearing 240 and the drive block 220 are in non-contact. Thus, when the motor on the carrier plate 140 starts, the motor applies torque and tension to the drive shaft 130, causing the drive shaft 130 to rise under the tension, thereby causing the flat bearing 240 to rise and abut against the drive block 220. Since the planar bearing 240 and the transmission block 220 are in rolling contact, the planar bearing 240 will only transmit the tension to the transmission block 220, which will then be detected by the tension sensor 210, allowing the tension sensor 210 to accurately measure the tension of the transmission shaft 130.

[0037] like Figures 1 to 5 As shown, the torque testing assembly 300 includes a torque sensor 310, a transmission pin 320, and two unloading bearings 330. The torque sensor 310 is disposed inside the sleeve 110 and is located below the transmission shaft 130. The transmission pin 320 is radially disposed on one end of the transmission shaft 130 near the torque sensor 310. The two unloading bearings 330 are rotatably disposed at both ends of the transmission pin 320, and both unloading bearings 330 are located inside the test end of the torque sensor 310. The transmission shaft 130 is used to drive the unloading bearings 330 to contact or move away from the torque sensor 310.

[0038] It should be noted that the torque sensor 310 is installed inside the sleeve 110, and is located below the drive shaft 130, with the test end of the torque sensor 310 coaxial with the drive shaft 130. Furthermore, the drive pin 320 passes radially through the drive shaft 130 and is installed inside it, with both ends of the drive pin 320 extending from opposite sides of the drive shaft 130. Further, two unloading bearings 330 are respectively installed at both ends of the drive pin 320, and both unloading bearings 330 are located within the test end of the torque sensor 310. It should be noted that in its natural state, the two unloading bearings 330 are not in contact with the test end of the torque sensor 310. When the motor starts testing, the motor transmits torque to the drive shaft 130 to rotate it. The drive shaft 130 drives the drive pin 320 to rotate, ultimately causing the unloading bearings 330 at both ends of the drive pin 320 to rotate and push against the test end of the torque sensor 310. Thus, by fixing a sufficiently long linear bearing 120 within the sleeve 110 and then fitting the drive shaft 130 through the linear bearing 120, the use of only the linear bearing 120 to support the drive shaft 130 reduces the number of transmission components, effectively resisting the vibration generated by the motor during testing of a high-load motor. During motor testing, the drive shaft 130 rotates under the torque of the motor and rises under tension. For the tension sensor 210, the torque of the drive shaft 130 is not transmitted to the transmission block 220 under the action of the plane bearing 240, allowing the tension sensor 210 to detect only the tension of the drive shaft 130. For the torque sensor 310, the tension is prevented from acting on it under the action of the unloading bearings 330 at both ends of the transmission pin 320, allowing the torque sensor 310 to detect only the torque of the drive shaft 130. Therefore, the testing accuracy of motor torque and tension is improved, and mutual interference between torque and tension is avoided during testing.

[0039] In one embodiment, the side of the transmission block 220 near the plane bearing 240 has a smooth structure. This effectively reduces the frictional force when the plane bearing 240 contacts and rolls with the transmission block 220, thereby further reducing the influence of torque on the tension sensor 210.

[0040] like Figure 4 As shown, in one embodiment, the planar bearing 240 includes a planar washer 241 and a plurality of balls 242. The planar washer 241 is disposed on the side of the threaded sleeve 230 near the transmission block 220, and each ball 242 is rotatably disposed on the planar washer 241.

[0041] It should be noted that the flat washer 241 has a groove, allowing the balls 242 to roll along the groove. When the drive shaft 130 rises, the flat washer 241 drives the balls 242 to abut against the smooth surface of the drive block 220. Thus, when the drive shaft 130 rotates, the balls 242 are in rolling contact with both the drive block 220 and the flat washer 241, effectively reducing frictional transmission.

[0042] like Figure 4 As shown, in one embodiment, the screw sleeve 230 has an annular groove 231 on the side near the transmission block 220, and each ball 242 is located in the annular groove 231.

[0043] Thus, by opening an annular groove 231 on the threaded sleeve 230, part of the structure of the transmission block 220 is located in the annular groove 231 even in its natural state, thereby preventing each ball 242 from falling out of the threaded sleeve 230 and ensuring that the transmission block 220 and the plane bearing 240 are in a non-contact state in their natural state.

[0044] In one embodiment, the threaded sleeve 230 has an internal thread, and the outer wall of the drive shaft 130 has an external thread, with the internal thread engaging with the external thread. Thus, the threaded sleeve 230 is screwed and fixed to the drive shaft 130, so that the threaded sleeve 230 confines the plane bearing 240 between it and the transmission block 220.

[0045] like Figure 4 As shown, in one embodiment, the tensile testing assembly 200 further includes a bushing 250, which is disposed on the drive shaft 130 and abuts against the threaded sleeve 230.

[0046] It should be noted that, in order to improve the firmness of the threaded sleeve 230 and prevent it from loosening from the drive shaft 130, a bushing 250 is provided to reinforce the threaded sleeve 230. Specifically, the bushing 250 is fitted onto the outer wall of the drive shaft 130, and the bushing 250 abuts against the threaded sleeve 230. Then, a nut screw is used to screw it onto one side of the bushing 250, so that the nut screw is fixed to the drive shaft 130.

[0047] like Figure 3 and Figure 5 As shown, in one embodiment, the torque testing assembly 300 further includes a positioning pin 340, which is radially disposed on the drive shaft 130. The drive shaft 130 is used to drive the positioning pin 340 and the drive pin 320 to rotate synchronously. When the unloading bearing 330 abuts against the test end of the torque sensor 310, the positioning pin 340 separates from the sleeve 110. When the positioning pin 340 abuts against the sleeve 110, the drive pin 320 separates from the test end of the torque sensor 310.

[0048] Specifically, the drive shaft 130 contacts the output shaft of the torque sensor 310 via two relief bearings 330. If the relief bearing 330 accidentally detaches from the drive pin 320, the drive pin 320 will directly push against the torque sensor 310 and damage it. Therefore, the above structure is proposed to protect the torque sensor 310. Specifically, the positioning pin 340 is radially inserted and fixed on the drive shaft 130, and both ends of the positioning pin 340 extend from opposite sides of the drive shaft 130, with the axis of the positioning pin 340 parallel to the axis of the drive pin 320. When the relief bearing 330 is not detached from the drive pin 320, the rotation of the drive shaft 130 drives the drive pin 320 and the positioning pin 340 to rotate simultaneously. When the relief bearing 330 contacts and pushes against the test end of the torque sensor 310, there is still a certain distance between the two ends of the positioning pin 340 and the sleeve 110, and the positioning pin 340 will not contact the sleeve 110. When the unloading bearing 330 detaches from the transmission pin 320, the transmission shaft 130 rotates, causing the transmission pin 320 and the positioning pin 340 to rotate simultaneously. Before the transmission pin 320 contacts the test end of the torque sensor 310, the positioning pin 340 will first abut against the sleeve 110, thereby preventing the transmission shaft 130 from continuing to rotate, that is, preventing the transmission pin 320 from continuing to rotate to contact and push against the test end of the torque sensor 310. In this way, the torque sensor 310 is effectively protected.

[0049] like Figure 1 and Figure 6 As shown, in one embodiment, the sleeve 110 includes a fixed seat 111 and a fixed sleeve 112. A linear bearing 120 is disposed in the fixed seat 111, a tension sensor 210 is disposed in the fixed seat 111, the fixed sleeve 112 is disposed at the bottom of the fixed seat 111, and a torque sensor 310 is disposed in the fixed sleeve 112.

[0050] Thus, the linear bearing 120 is installed in the fixed base 111, the drive shaft 130 is installed in the linear bearing 120, the tension sensor 210 is installed at the bottom of the fixed base 111, the torque sensor 310 is installed in the fixed sleeve 112, and finally the fixed sleeve 112 is fixedly installed at the bottom of the fixed base 111 with screws.

[0051] like Figure 3 and Figure 6 As shown, in one embodiment, a clearance groove 1111 is provided on the inner side wall of the fixing base 111, and the end of the positioning pin 340 is located in the clearance groove 1111.

[0052] It should be noted that there are two clearance slots 1111, located on opposite sides of the inner wall of the fixed base 111, so that the ends of the two locating pins 340 are respectively located in the two clearance slots 1111. Thus, when the unloading bearing 330 accidentally falls off, the locating pins 340 rotate to contact the inner wall of the clearance slots 1111, preventing the drive shaft 130 from continuing to rotate, thereby preventing the drive pin 320 from continuing to rotate to contact the test end of the torque sensor 310.

[0053] like Figure 2 As shown, in one embodiment, the tensile testing assembly 200 further includes a silicone sheet 260, which is sleeved on the drive shaft 130 and is used to abut against the tensile sensor 210.

[0054] It should be noted that after the motor completes the test, the drive shaft 130 will fall back, causing it to contact the housing of the tension sensor 210. To avoid a hard contact between the drive shaft 130 and the housing of the tension sensor 210, a silicone sheet 260 is fitted at the step position where the drive shaft 130 contacts the housing of the tension sensor 210, ensuring that the silicone sheet 260 contacts the housing of the tension sensor 210. In one embodiment, the silicone sheet 260 is glued to the drive shaft 130 to prevent it from falling off.

[0055] like Figure 4 As shown, in one embodiment, the tensile testing assembly 200 further includes an O-ring 270, which is sleeved on the drive shaft 130 and abuts against the threaded sleeve 230. Thus, the O-ring 270 eliminates the gap between the threaded sleeve 230 and the drive shaft 130, preventing lubricating oil on the plane bearing 240 from flowing down through the gap in the threaded sleeve 230.

[0056] The embodiments described above are merely illustrative of several implementations of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the invention patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the protection scope of the present invention. Therefore, the protection scope of this invention patent should be determined by the appended claims.
