Description

Technical Field

[0001] This utility model relates to the field of tripod calibration technology, and in particular to an intelligent washing machine tripod calibration device. Background Technology

[0002] The washing machine tripod is an important component installed at the bottom of the washing machine to support and fix related parts of the washing machine. It generally consists of three support arms and a bushing. The three support arms are arranged in a radiating pattern around the bushing and are connected to the bushing by welding or other processes. The bushing is usually connected to the rotating shaft. Some tripods are also equipped with components such as a balancer. If the tripod is not in the correct position or is deformed, the washing machine will not be able to maintain balance during operation and will shake violently. Therefore, it needs to be measured and calibrated before leaving the factory.

[0003] A search of Chinese patent publication number "CN212181322U" reveals a "tripod calibration and leveling device". By placing the tripod on a workbench, a hand is inserted into the handheld slot, and a push-pull plate is used to move the electric push rod. Simultaneously, sliders two and one slide on slide rails two and one to support the displacement of the electric push rod. A distance sensor is activated to detect the height of various parts of the tripod and output the result to the display screen. This allows for easy identification of errors from the standard value. The electric push rod then drives the mounting column and leveling cone to raise and lower, leveling the tripod and adjusting various parts accordingly.

[0004] Based on the above search and existing technology, it was found that the above patent has certain defects. When the device is in use, it mainly relies on a distance sensor for measurement. Although it can complete the measurement of the tripod, due to the special shape of the tripod and the presence of multiple legs, it cannot quickly complete the measurement of multiple legs of the tripod in a short period of time. Its working efficiency is insufficient and needs to be improved. Utility Model Content

[0005] (a) Technical problems to be solved

[0006] To address the shortcomings of existing technologies, this utility model provides an intelligent washing machine tripod correction device, which solves the technical problem of insufficient working efficiency of existing devices.

[0007] (II) Technical Solution

[0008] To achieve the above objectives, this utility model provides the following technical solution:

[0009] A smart washing machine tripod calibration device includes a base;

[0010] The upper end of the base is provided with a calibration and measurement structure;

[0011] The calibration measurement structure includes a circular ring. Multiple parallel rods are fixedly mounted on the circumferential surface of the ring. Each parallel rod has a groove inside, and a lead screw is rotatably mounted inside each groove. Each lead screw is partially exposed inside the ring and rotatably mounted to the ring. A slider is fixedly mounted on the circumferential surface of each lead screw, and each slider is located inside the groove and slidably mounted to the groove. An ultrasonic distance sensor is embedded and fixedly mounted inside each slider. A driven bevel gear is fixedly mounted on the circumferential surface of each lead screw, and each driven bevel gear is located inside the ring. A servo motor is fixedly mounted inside the ring, and a driving bevel gear is fixedly mounted on the output shaft of the servo motor. The driving bevel gear meshes with the driven bevel gear, causing the lead screw to rotate and generate threaded transmission with the slider, thus moving the ultrasonic distance sensor along the lead screw.

[0012] Preferably, each of the slide grooves has symmetrically formed limit grooves on its inner wall, and each limit groove has a limit block slidably installed inside it. Each limit block is located on both sides of the slider and is fixedly installed with the slider.

[0015] (III) Beneficial Effects

[0016] Firstly, by setting up a calibration measurement structure, multiple parallel rods are set on the ring, and sliders and ultrasonic distance sensors are set inside the parallel rods. When the operator turns on the servo motor, the active bevel gear rotates and meshes with each driven bevel gear.

At this time, the ultrasonic distance sensor will measure the surface of the support leg in real time, and the measured data will be transmitted to the control unit. This allows for the rapid measurement of each support leg on the tripod, improving work efficiency.

[0017] Secondly, by setting limit grooves and limit blocks, when the slider moves the ultrasonic distance sensor in the chute, the slider will drive the limit block to slide in the limit groove, thereby providing additional limit and increasing stability. In addition, by setting a control unit, the data processing of the ultrasonic distance sensor can be completed, as well as the recording and comparison with process standard data, thereby completing intelligent processing.

Detailed Implementation

[0025] This application provides an intelligent washing machine tripod calibration device, effectively solving the technical problem of insufficient working efficiency in existing devices. By setting a calibration and measurement structure, multiple parallel rods are arranged on a ring, and sliders and ultrasonic distance sensors are installed inside the parallel rods. When the operator turns on the servo motor, the active bevel gear rotates and meshes with each driven bevel gear. The driven bevel gears drive the lead screw to rotate and engage with the slider via a threaded transmission. This causes the slider to move the ultrasonic distance sensor in a sliding groove. The ultrasonic distance sensor then measures the surface of the tripod legs in real time, and the measured data is transmitted to the control unit. This allows for rapid measurement of each leg of the tripod, improving work efficiency. Furthermore, by setting a limiting groove and a limiting block, when the slider moves the ultrasonic distance sensor in the sliding groove, the slider will cause the limiting block to slide within the limiting groove, providing additional limiting and increasing stability. Finally, by setting a control unit, the ultrasonic distance sensor data can be processed, and data can be recorded and compared with process standard data, thus achieving intelligent processing.

[0026] Example

[0027] like Figure 1 - Figure 5 As shown, the technical solution in this application embodiment effectively solves the technical problem of insufficient working efficiency of existing devices. The overall idea is as follows:

[0028] To address the problems existing in the prior art, this utility model provides an intelligent washing machine tripod correction device, including a base 11;

[0029] The upper end of the base 11 is provided with a calibration and measurement structure;

[0030] The calibration and measurement structure includes a circular ring 12. Multiple parallel rods 13 are fixedly mounted on the circumferential surface of the circular ring 12. Each parallel rod 13 has a groove 14 inside, and a lead screw 15 is rotatably mounted inside each groove 14. Each lead screw 15 is partially exposed inside the circular ring 12 and rotatably mounted with the circular ring 12. A slider 16 is fixedly mounted on the circumferential surface of each lead screw 15. Each slider 16 is located inside the groove 14 and slidably mounted with the groove 14. Each slider 16 is also embedded and fixedly mounted inside the groove 14. An ultrasonic distance sensor 17 is provided. Each lead screw 15 has a driven bevel gear 18 fixedly mounted on its circumferential surface. Each driven bevel gear 18 is located inside a ring 12. A servo motor 19 is fixedly mounted inside the ring 12. An active bevel gear 21 is fixedly mounted on the output shaft of the servo motor 19. The active bevel gear 21 meshes with the driven bevel gear 18. The active bevel gear 21 can mesh with the driven bevel gear 18 to make the lead screw 15 rotate and generate threaded transmission with the slider 16, thereby driving the ultrasonic distance sensor 17 to move along the lead screw 15.

[0031] By setting up a calibration measurement structure, multiple parallel rods 13 are set on the ring 12, and sliders 16 and ultrasonic distance sensors 17 are set inside the parallel rods 13. When the operator turns on the servo motor 19, the active bevel gear 21 rotates and meshes with each driven bevel gear 18. The driven bevel gears 18 drive the lead screw 15 to rotate and generate threaded transmission with the slider 16. The slider 16 drives the ultrasonic distance sensor 17 to move in the slide groove 14. At this time, the ultrasonic distance sensor 17 will measure the surface of the support leg in real time, and the measured data will be transmitted to the control unit 29. This allows for the rapid measurement of each support leg on the tripod, improving work efficiency.

[0032] Each slide 14 has a symmetrically provided limit groove 22 on its inner wall. Each limit groove 22 has a limit block 23 slidably installed inside it. Each limit block 23 is located on both sides of the slider 16. Each limit block 23 is fixedly installed with the slider 16.

[0033] By setting the limiting groove 22 and the limiting block 23, when the slider 16 drives the ultrasonic distance sensor 17 to move in the slide groove 14, the slider 16 will drive the limiting block 23 to slide in the limiting groove 22, thereby providing additional limiting and increasing stability.

[0034] A housing frame 24 is fixedly installed on the upper end of the base 11. An electric push rod 25 is fixedly installed on the upper end of the housing frame 24. The output shaft of the electric push rod 25 is slidably installed with the housing frame 24. A transmission plate 26 is fixedly installed on the output shaft of the electric push rod 25. The transmission plate 26 is located above the ring 12. The transmission plate 26 is fixedly installed with the ring 12. Multiple sliding columns 27 are fixedly installed between the base 11 and the housing frame 24.

[0035] By setting the slide column 27, when the output shaft of the electric push rod 25 pushes the transmission plate 26 to move, the transmission plate 26 will slide on the slide column 27, thereby providing a limit and ensuring the parallelism between the workpiece and the overall calibration and measurement structure.

[0036] Each sliding column 27 is slidably mounted with the transmission plate 26. The upper end of the base 11 is provided with a three-point pneumatic gripper disk 28, and the surface of the base 11 is provided with a control unit 29.

[0037] By setting up a three-point pneumatic gripper plate 28, the tripod can be fixed. By setting up a control unit 29 (which mainly consists of a PLC controller, a communication unit, a touch screen unit, etc.), the data processing of the ultrasonic distance sensor 17 (which emits ultrasonic pulses and receives ultrasonic signals reflected back from the object being measured, calculates the distance between the sensor and the object based on the time it takes for the ultrasonic waves to travel in the air, and obtains the height information of the tripod legs) can be completed, as well as the recording and comparison with process standard data, thereby completing intelligent processing.

[0038] Working principle:

[0039] The first step is to place the tripod on the three grippers of the three-point pneumatic gripper disk 28 and fix the tripod by opening the three-point pneumatic gripper disk 28 through the control unit 29. Then, the operator can use the control unit 29 to open the electric push rod 25, so that the output shaft of the electric push rod 25 pushes the transmission plate 26 to one side of the three-point pneumatic gripper disk 28, and then the transmission plate 26 slides down on the slide column 27. When the bottom of the ring 12 is in contact with the center point of the tripod, the operator can stop the electric push rod 25.

[0040] The second step involves the operator measuring whether the curved surfaces of each leg of the tripod meet the tolerance requirements. At this point, the operator can activate the servo motor 19 via the control unit 29, causing the output shaft of the servo motor 19 to drive the active bevel gear 21 to rotate. This causes the active bevel gear 21 to mesh with each driven bevel gear 18, which in turn drives the lead screw 15 to rotate and engages with the slider 16 via a threaded transmission. The slider 16 then moves the ultrasonic distance sensor 17 within the slide groove 14. The ultrasonic distance sensor 17 measures the surface of the legs in real time, and the measured data is transmitted to the control unit 29. If the measured tolerance data is unqualified, the control unit 29 will trigger an alarm. The operator can then use the data from the control unit 29 to correct and rework the tripod.

[0041] Finally, it should be noted that the above embodiments are merely examples for clearly illustrating the present invention and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
