Description

Technical Field

[0001] This utility model belongs to the field of multidimensional force sensor measurement, specifically a multidimensional force sensor loading device. Background Technology

[0002] In modern industrial production and scientific research, multidimensional force sensors are an important measurement tool and are widely used in robot control, precision machining, mechanical performance testing and other fields. In order to ensure the measurement accuracy of multidimensional force sensors, loading devices are used to calibrate and test them.

[0003] First, place the multi-dimensional force sensor on the loading device. Since the loading unit is mostly fixed, it is necessary to use positioning parts to initially position the sensor according to the position and direction of the loading unit, so that one measuring axis of the sensor is aligned with the loading direction, which facilitates the measurement of the sensor. After the measurement of one direction is completed, remove the multi-dimensional force sensor from the loading device. If the loading of the next direction is required, repeat the above process and adjust the sensor position according to the direction to be measured, so as to complete the multi-directional measurement of the multi-dimensional sensor.

[0004] However, in actual use, since the position and direction of the loading unit are fixed during use, when it is necessary to load the multi-dimensional force sensor in different directions or angles, personnel need to frequently disassemble and adjust the sensor's measurement orientation to adapt to the position and direction of the loading unit. This frequent adjustment not only increases the complexity of operation but also greatly reduces the loading efficiency.

[0005] In summary, this utility model provides a multi-dimensional force sensor loading device to solve the above problems. Utility Model Content

[0007] A multidimensional force sensor loading device includes a base, a placement unit on the top of the base, and a multidimensional force sensor body inside the placement unit. A second loading unit is located on one side of the base, and a first loading unit is located above the placement unit. A microcontroller is located on one side of the first loading unit. The placement unit includes a limiting seat, and a first geared motor is fixedly connected to the bottom of the base. The output shaft of the first geared motor is drivenly connected to the limiting seat. The first loading unit includes a connecting box, and a second geared motor is fixedly connected to one side of the connecting box.

[0013] Beneficial effects: This utility model has the following beneficial effects:

[0014] This invention uses a limiting seat to initially limit the position of the multi-dimensional force sensor body. With the power of the first geared motor, the limiting seat and the multi-dimensional force sensor body can easily rotate, thereby flexibly adjusting the measurement orientation of the multi-dimensional force sensor body and laying a solid foundation for subsequent multi-directional measurements. Driven by the second geared motor, the first screw rotates precisely, thereby driving the first movable block and the first cylinder to move smoothly, allowing the first cylinder to be accurately positioned above the measuring axis of the multi-dimensional force sensor body. Simultaneously, the third geared motor drives the second screw to rotate, causing the second movable block and the second cylinder to move flexibly, ensuring the second cylinder...

The embodiments of this disclosure are not necessarily defined to include all aspects of this utility model.

Furthermore, some aspects of this utility model can be used alone or in any suitable combination with other aspects disclosed in this utility model.

[0023] Example 1

[0024] like Figure 1-5 As shown, this is the first embodiment of the present invention. This embodiment provides a multi-dimensional force sensor loading device, including a base 1, a placement unit 2 disposed on the top of the base 1, and a multi-dimensional force sensor body 6 disposed in the inner cavity of the placement unit 2. A second loading unit 4 is disposed on one side of the base 1, and a first loading unit 3 is disposed above the placement unit 2. A microcontroller 5 is disposed on one side of the first loading unit 3. The placement unit 2 includes a limiting seat 21, and a first reduction motor 22 is fixedly connected to the bottom of the base 1. The output shaft of the first reduction motor 22 is drively connected to the limiting seat 21. The first loading unit 3 includes a connecting... The second loading unit 4 includes a fixed box 41, and a third geared motor 42 is fixedly connected to one side of the fixed box 41. The output shaft of the second geared motor 32 is driven by a first screw 33, and a first movable block 34 is threadedly connected to the surface of the first screw 33. A first cylinder 35 is fixedly connected to the bottom of the first movable block 34. The second loading unit 4 includes a fixed box 41, and a third geared motor 42 is fixedly connected to one side of the fixed box 41. The output shaft of the third geared motor 42 is driven by a second screw 43, and a second movable block 44 is threadedly connected to the surface of the second screw 43. A second cylinder 45 is fixedly connected to one side of the second movable block 44.

[0025] like Figure 1-5As shown, by placing the multi-dimensional force sensor body 6 inside the limiting seat 21, the limiting seat 21 can initially limit the multi-dimensional force sensor body 6. Then, the microcontroller 5 activates either the second reduction motor 32 or the third reduction motor 42. Since both the second reduction motor 32 and the third reduction motor 42 are servo reduction motors, their output shafts can rotate in both directions. The output shaft of the second reduction motor 32 can drive the first screw 33 to rotate in both directions. Because the first screw 33 and the first movable block 34 are threadedly connected, the rotation of the first screw 33 simultaneously drives the first movable block 34 and the first... The cylinder 35 moves to one side, positioning itself above the measuring axis of the multi-dimensional force sensor body 6, longitudinally aligned with it. The output shaft of the third reduction motor 42 drives the second screw 43 to rotate in both directions. Since the second screw 43 and the second movable block 44 are threadedly connected, the rotation of the second screw 43 simultaneously moves the second movable block 44 and the second cylinder 45 to one side, allowing the second cylinder 45 to move to one side of the measuring axis of the multi-dimensional force sensor body 6, laterally aligned with it. This facilitates automatic adjustment based on the position of the measuring axis of the multi-dimensional force sensor body 6. Adjusting the positions of the second cylinder 45 and the first cylinder 35, and activating the first geared motor 22 via the microcontroller 5, allows the limit seat 21 and the multi-dimensional force sensor body 6 to rotate. Since the first geared motor 22 is a stepper motor and the microcontroller 5 is an ESP32 series microcontroller, the microcontroller 5, in conjunction with the first geared motor 22, can precisely adjust the measuring orientation of the multi-dimensional force sensor body 6. This facilitates subsequent multi-directional measurement of the multi-dimensional force sensor body 6. Movement of the output end of the first cylinder 35 or the second cylinder 45 causes the output end of the first cylinder 35 or the second cylinder 45 to be aligned with the measuring... The force applied by the first cylinder 35 or the second cylinder 45 is transmitted to the multi-dimensional force sensor body 6 through the measuring shaft. The multi-dimensional force sensor body 6 senses the applied force value, and the force value data is transmitted to the microcontroller 5. The microcontroller 5 can then compare and analyze the force value data output by the first cylinder 35 or the second cylinder 45 with the force value data sensed by the multi-dimensional force sensor body 6 to realize the measurement operation of the multi-dimensional force sensor body 6. By measuring the multi-directional multi-dimensional force sensor body 6, the orientation can be automatically adjusted without frequent disassembly and adjustment of the multi-dimensional force sensor body 6, which effectively improves the measurement efficiency of the multi-dimensional force sensor body 6.

[0026] Example 2

[0027] Reference Figure 1 and 4 This is the second embodiment of the present invention, which is based on the previous embodiment.

[0028] In this embodiment, a positioning rod 23 is threadedly connected to the front of the limiting seat 21, and one end of the positioning rod 23 is in contact with the multi-dimensional force sensor body 6. The output ends of the first cylinder 35 and the second cylinder 45 are both in contact with the measuring axis of the multi-dimensional force sensor body 6.

[0029] Both sides of the connecting box 31 are fixedly connected to the first through groove 312, and one side of the first through groove 312 is fixedly connected to the base 1. The bottom of the fixing box 41 is fixedly connected to the second through groove 412, and the bottom of the second through groove 412 is fixedly connected to the base 1.

[0030] like Figure 1 and 4 As shown, the positioning rod 23 is threadedly connected to the limiting seat 21. During rotation, one end of the positioning rod 23 gradually moves to one side until it contacts the multi-dimensional force sensor body 6, thereby positioning the multi-dimensional force sensor body 6 and ensuring its stability during load measurement. The output ends of the first cylinder 35 and the second cylinder 45 are in contact with the multi-dimensional force sensor body 6, facilitating the transmission of the applied force. The first through groove 312 provides stable support for the connecting box 31, and the second through groove 412 provides stable support for the fixing box 41, thus ensuring the stability of the connecting box 31 and the fixing box 41 during use.

[0031] Example 3

[0032] Reference Figure 1 , 2 4 and 5 are the third embodiment of this utility model, which is based on the first two embodiments.

[0033] In this embodiment, a support plate 311 is provided at the bottom of the connecting box 31, and the bottom of the first movable block 34 passes through the inner cavity of the support plate 311 and is slidably connected to the inner cavity of the support plate 311.

[0034] The front of the fixed box 41 is provided with a support frame 411, and the front of the second movable block 44 passes through the inner cavity of the support frame 411 and is slidably connected to the inner cavity of the support frame 411.

[0035] A display screen is provided on one side of the microcontroller 5, and the input terminal of the display screen is connected to the output terminal of the microcontroller 5. The output terminal of the multi-dimensional force sensor body 6 is connected to the input terminal of the microcontroller 5. The output terminal of the microcontroller 5 is connected to the input terminals of the first cylinder 35 and the second cylinder 45, respectively. The input terminals of the first geared motor 22, the second geared motor 32, and the third geared motor 42 are all connected to the output terminal of the microcontroller 5.

[0036] like Figure 1 , 2As shown in Figures 4 and 5, the second movable block 44 can move along the inner cavity trajectory of the support frame 411 during movement, thereby limiting the movement of the second movable block 44 and preventing misalignment when driving the second cylinder 45. The first movable block 34 slides along the inner cavity of the support plate 311 during movement, ensuring the stability of the first movable block 34 when driving the first cylinder 35 and preventing positional deviation during movement. A display screen is provided on one side of the microcontroller 5, allowing the microcontroller 5 to display the applied pressure data and the multi-dimensional force sensor body 6. All pressure data is transmitted to the display screen for easy viewing. The multi-dimensional force sensor body 6 is connected to the microcontroller 5, which allows the multi-dimensional force sensor body 6 to transmit the sensed pressure data to the microcontroller 5 for analysis. The microcontroller 5 is connected to the first geared motor 22, the second geared motor 32, the third geared motor 42, the first cylinder 35, and the second cylinder 45, respectively, which facilitates the operation or shutdown of the first geared motor 22, the second geared motor 32, the third geared motor 42, the first cylinder 35, and the second cylinder 45, thereby enabling automated operation and improving ease of use.

[0037] In use, the multi-dimensional force sensor body 6 is first placed in the inner cavity of the limiting seat 21, thus the limiting seat 21 initially limits the multi-dimensional force sensor body 6. Next, the positioning rod 23 is rotated. Since the positioning rod 23 and the limiting seat 21 are threaded together, the positioning rod 23 gradually moves to one side while moving, thus contacting the multi-dimensional force sensor body 6 and clamping and positioning it, ensuring the stability of the multi-dimensional force sensor body 6 during load measurement. Then, the microcontroller 5 activates the first reduction motor 22 and controls the rotation angle of the output shaft of the first reduction motor 22. The output shaft of the first reduction motor 22 drives the limiting seat 21 to rotate, and the limiting seat 21 drives the multi-dimensional force sensor body... 6. Rotate to the set position to adjust the measuring orientation of the multi-dimensional force sensor body 6 as needed. Then, the microcontroller 5 activates the second reduction motor 32, which drives the first screw 33 to rotate via its output shaft. Since the first screw 33 and the first movable block 34 are threadedly connected, the rotation of the first screw 33 simultaneously moves the first movable block 34 and the first cylinder 35 to one side, positioning the first cylinder 35 above the measuring axis of the multi-dimensional force sensor body 6 and aligning it longitudinally. Next, the microcontroller 5 activates the first cylinder 35, applying a set pressure downwards from its output until the output of the first cylinder 35 aligns with the measuring axis of the multi-dimensional force sensor body 6. The measuring shaft contacts the first cylinder 35, transmitting the pressure applied by the first cylinder 35 to the multi-dimensional force sensor body 6. The multi-dimensional force sensor body 6 senses the applied force and transmits the sensed data to the microcontroller 5. The microcontroller 5 then compares and analyzes the force value data output by the first cylinder 35 with the force value data sensed by the multi-dimensional force sensor body 6 to determine the longitudinal orientation of the multi-dimensional force sensor body 6. Afterwards, the microcontroller 5 activates the third reduction motor 42. The output shaft of the third reduction motor 42 drives the second screw 43 to rotate. Since the second screw 43 and the second movable block 44 are threadedly connected, the rotation of the second screw 43 can drive the second movable block 44 and the second cylinder 45 to move to one side, thus... The second cylinder 45 can move to one side of the measuring axis of the multi-dimensional force sensor body 6, aligning it laterally with the measuring axis. Then, the microcontroller 5 activates the second cylinder 45, causing it to apply a set pressure and move downwards until its output contactes the measuring axis of the multi-dimensional force sensor body 6. The force applied by the second cylinder 45 is then transmitted to the multi-dimensional force sensor body 6 via the measuring axis. The multi-dimensional force sensor body 6 senses the applied force value, and this force data is transmitted to the microcontroller 5. The microcontroller 5 then compares and analyzes the force data output by the second cylinder 45 with the force data sensed by the multi-dimensional force sensor body 6, thereby determining the lateral orientation of the multi-dimensional force sensor body 6.By measuring the multi-directional force sensor body 6 in multiple directions, the body 6 can automatically adjust its orientation as needed. Furthermore, both the second cylinder 45 and the first cylinder 35 can automatically adjust according to the position of the measuring axis of the multi-dimensional force sensor body 6. This fully automated operation eliminates the need for frequent disassembly and adjustment of the multi-dimensional force sensor body 6, thereby improving the efficiency and convenience of subsequent measurements.
