Description

Technical Field

[0001] This utility model relates to the field of force sensor technology, and in particular to an easy-to-install insert-type force sensor. Background Technology

[0002] When in use, the force sensor is inserted into the component. The deformable force point of the force sensor is in contact with the surface of the back component. When the component being measured is subjected to force, the force sensor can be used to measure the external force on the component.

[0003] Components often have varied shapes, and in force measurement tests, some components are tubular, requiring force sensors to be inserted inside. Furthermore, the force sensors need to be moved multiple times to measure the forces acting at multiple points on the tubular component. Existing force sensors cannot be quickly inserted into the tubular component and stably installed. This application provides an easily installable insertable force sensor, solving the aforementioned technical problems. Utility Model Content

[0004] Based on the above situation, the main purpose of this utility model is to provide an easy-to-install insert-type force sensor to solve the problem that the force sensor cannot be quickly inserted into the tubular component being measured and installed stably.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] An easy-to-install insert force sensor includes a sensor body, a mounting bracket, and an insertion assembly;

[0007] The insertion assembly includes a drive rod, a connecting plate, and a support rod. Multiple support rods are provided. One end of each support rod and drive rod is connected to the connecting plate. The multiple support rods and drive rods are arranged along the circumference of the connecting plate. The ends of each support rod and drive rod away from the connecting plate are respectively provided with a support wheel and a drive wheel. The support wheel and drive wheel can abut against the inner side of the tubular component.

[0008] The mounting bracket is fixed to the support rod, and the sensor body is fixed to the mounting bracket.

[0011] The support rod is rotatably connected to a second turntable at one end away from the connecting plate. Two second upright plates are fixed to the side of the second turntable away from the support rod, and the support wheel is rotatably connected between the two second upright plates.

[0012] Preferably, there are two infeed components, and the two infeed components are connected by a connecting rod.

[0013] Preferably, the drive rod has a receiving groove in the middle, and a first servo motor is fixed in the receiving groove. The output shaft of the first servo motor is fixed to the first turntable.

[0014] Preferably, a first electric push rod is fixed to one side of the drive rod. The length direction of the first electric push rod is the same as the radial direction of the connecting plate. A pressure plate is fixed to the telescopic end of the first electric push rod, and the pressure plate can abut against the inside of the tubular component.

[0015] Preferably, a rubber pad is fixed to the surface of the pressure plate.

[0030] In the description of this utility model, it should be understood that the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance. Furthermore, in the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

[0031] Reference Figure 1-3 This utility model provides an easy-to-install insert-type force sensor, including a sensor body 1, an insertion component 2, and a mounting bracket 3. The mounting bracket 3 is fixed to the insertion component 2, and the sensor body 1 is fixed to the mounting bracket 3. The insertion component 2 can be inserted from the end of the tubular component and can move into the interior of the tubular component to move and fix the sensor body 1 to the detection point.

[0032] The guide assembly 2 includes a drive rod 21, a connecting plate 22, and a support rod 23. Two support rods 23 are provided, and both support rods 23 and the drive rod 21 are connected to the connecting plate 22. Multiple support rods 23 and drive rods 21 are arranged along the circumference of the connecting plate 22. When the guide assembly 2 is located within the tubular component, the connecting plate 22 and the tubular component are coaxially arranged. Two guide assemblies 2 can be provided, and the connecting plates 22 of the two guide assemblies 2 can be fixed together by a connecting rod, which is coaxial with the connecting plate 22. The mounting bracket 3 can be fixed to the support rods 23. It should be noted that more support rods 23 can be provided; however, the combination of two support rods 23 and one drive rod 21 is sufficient to provide sufficient strength to support the mounting bracket 3, and the cost and weight are relatively low.

[0033] The end of the drive rod 21 away from the connecting plate 22 is rotatably connected to the drive wheel 211, and the end of the support rod 23 away from the connecting plate 22 is rotatably connected to the support wheel 231. Both the support wheel 231 and the drive wheel 211 can abut against the inside of the tubular component, stably mounting the inlet assembly 2 inside the tubular component. The rotation of the drive wheel 211 and the support wheel 231 allows the inlet assembly 2 to enter the tubular component.

[0034] Mounting frame 3 includes a connecting beam 31, a mounting plate 311, and a mounting cylinder 32. The connecting beam 31 is fixed to the support rod 23, the mounting plate 311 is fixed to the connecting beam 31, and the mounting cylinder 32 is fixed to the surface of the mounting plate 311. The sensor body 1 can be fixed inside the mounting cylinder 32. The housing of the sensor body 1 can be externally mounted on the mounting cylinder 32 with a lug, thus fixing the sensor body 1 inside the mounting cylinder 32. The force measuring point of the sensor body 1 can contact the inner side of the tubular component. When the tubular component is subjected to force, the sensor body 1 can measure the external force on the tubular component.

[0035] A first electric push rod 212 is fixed to one side of the drive rod 21. The length direction of the first electric push rod 212 is the same as the radial direction of the connecting plate 22. A pressure plate 2121 is fixed to the telescopic end of the first electric push rod 212, and the pressure plate 2121 can abut against the inside of the tubular component. The first electric push rod 212 can press the pressure plate 2121 against the inside of the tubular component, thereby fixing the position of the inserted component 2 and quickly fixing the position of the sensor body 1.

[0036] As one embodiment, a rubber pad 2122 is fixed on the side of the pressure plate 2121 away from the first electric push rod 212. The rubber pad 2122 can increase the friction between the pressure plate 2121 and the tubular component, and also make the contact between the pressure plate 2121 and the tubular component tighter.

[0037] In use, the sensor body 1 can be fixed in the mounting cylinder 32. After confirming the measurement position, the infeed component 2 is inserted into the tubular component. The rotation of the drive wheel 211 and the support wheel 231 can drive the infeed component 2 to move into the tubular component, thereby pushing the sensor body 1 into the detection position. The first electric push rod 212 works to fix the infeed component 2 in the tubular component, completing the fixation of the sensor body 1. This allows the force sensor to be quickly inserted into the tubular component and quickly installed and fixed in the tubular component, improving detection efficiency.

[0038] As one embodiment, a first telescopic rod 221 is connected between the connecting plate 22 and the drive rod 21 and the support rod 23. A first spring 222 is sleeved on the outside of each first telescopic rod 221. Under normal conditions, the first spring 222 can push the drive wheel 211 and the support wheel 231 to press against the inner wall of the tubular component, so that the drive wheel 211 and the support wheel 231 can be in close contact with the tubular component, and can make the insertion component 2 adaptable to tubular components with radial dimensions within a certain range, thereby improving the flexibility of the insertion component 2.

[0039] In one embodiment, a first turntable 213 is rotatably connected to the end of the drive rod 21 away from the connecting plate 22. Two first upright plates 214 are fixed to the side of the first turntable 213 away from the drive rod 21, and a drive wheel 211 is rotatably connected between the two first upright plates 214. A second turntable 232 is rotatably connected to the end of the support rod 23 away from the connecting plate 22. Two second upright plates 233 are fixed to the side of the second turntable 232 away from the support rod 23, and a support wheel 231 is rotatably connected between the two second upright plates 233. The arrangement of the first turntable 213 and the second turntable 232 can adjust the direction of the drive wheel 211 and the support wheel 231, so that the stepping component 2 can move axially along the tubular component and can also rotate circumferentially in the tubular component to adjust the position of the sensor body 1.

[0040] Furthermore, each drive rod 21 has a receiving groove 215 in its middle, and a first servo motor 216 is fixed in the receiving groove 215. The output shaft of the first servo motor 216 is fixed to the first turntable 213. The operation of the first servo motor 216 can adjust the rolling direction of the drive wheel 211, thereby adjusting the moving direction of the feed assembly 2. A second servo motor 217 is fixed to the side of one of the first upright plates 214 in the feed assembly 2. The output shaft of the second servo motor 217 extends to the position between the two first upright plates 214 and the axis of the drive wheel 211 and is fixed. When the second servo motor 217 is working, it drives the drive wheel 211 to rotate, which can move the feed assembly 2. It should be noted that both feed assemblies 2 can be driven by the first servo motor 216 and the second servo motor 217, or the drive can be set on a single feed assembly 2. However, setting the drive on both feed assemblies 2 results in higher driving efficiency and smoother movement of the feed assembly 2.

[0041] As one embodiment, the mounting frame 3 includes two connecting beams 31, which are respectively fixed in the two infeed components 2. Specifically, the connecting beams 31 are fixed between the two support rods 23, and a square plate 33 is fixed between the two connecting beams 31. Multiple second telescopic rods 34 are fixed on the surface of the square plate 33. The end of the second telescopic rod 34 away from the square plate 33 is fixed to the mounting plate 311, so that the distance between the mounting plate 311 and the square plate 33 can be adjusted. A second electric push rod 331 is fixed on the square plate 33. The telescopic rod of the second electric push rod 331 is connected to the mounting plate 311, so as to adjust the position of the sensor body 1 and avoid the sensor body 1 from contacting the inner side of the tubular component when the infeed component 2 moves, thus preventing wear.

[0042] Furthermore, an extension plate 332 is fixed to the end of the second electric push rod 331, and a second spring 333 is fixed between the extension plate 332 and the mounting plate 311. The second spring 333 can buffer the push of the second electric push rod 331 to prevent the second electric push rod 331 from pushing too hard and damaging the sensor body 1.

[0043] The implementation principle of this utility model is as follows: In use, the sensor body 1 can be fixed in the mounting cylinder 32. After confirming the measurement position, the infeed component 2 is inserted into the tubular component. The rotation of the drive wheel 211 and the support wheel 231 can drive the infeed component 2 to move into the tubular component, thereby pushing the sensor body 1 into the detection position. The first electric push rod 212 works to fix the infeed component 2 in the tubular component, completing the fixation of the sensor body 1. This allows the force sensor to be quickly inserted into the tubular component and quickly installed and fixed in the tubular component, improving detection efficiency.

[0044] Those skilled in the art will understand that, without conflict, the above-mentioned preferred solutions can be freely combined and superimposed.

[0045] It should be understood that the above-described embodiments are merely exemplary and not restrictive. Without departing from the basic principles of this utility model, any obvious or equivalent modifications or substitutions made by those skilled in the art regarding the above details will be included within the scope of the claims of this utility model.
