[0044] Reference Figures 1 to 4 As shown, this embodiment provides an elastic force detection device, which includes a spring force measuring assembly 100 , a carrier 200 and a driving member 300 .

[0045] Specifically, the spring force measuring assembly 100 includes a test platform 110, a pressure sensor 120 and a pressure rod 130, wherein the pressure sensor 120 is arranged on the test platform 110, and the pressure rod 130 is arranged on a side of the pressure sensor 120 away from the test platform 110; the carrier 200 is arranged on the pressure sensor 120 and is located between the pressure sensor 120 and the pressure rod 130 along the first direction, and the carrier 200 is used to place the elastic member 10; the driving member 300 is connected to the pressure rod 130, and the driving member 300 is used to drive the pressure rod 130 to squeeze the elastic member 10 along the first direction.

[0046] In this embodiment, the elastic member 10 is placed on the carrier 200, and the driving member 300 drives the pressure rod 130 to squeeze the elastic member 10 along the first direction, so that the elastic member 10 undergoes elastic deformation, and the elastic force generated by the elastic deformation of the elastic member 10 acts on the carrier 200, and is transmitted to the pressure sensor 120 through the carrier 200, thereby realizing the elastic force detection of the elastic member 10, which is more efficient than the traditional manual downward pressure detection. In addition, by setting the driving member 300, it is possible to ensure that the movement of the pressure rod 130 is stable and the movement amount is consistent, thereby ensuring the accuracy of the data detected by the pressure sensor 120, and effectively improving the data accuracy detected by the pressure sensor 120.

[0047] Exemplarily, the elastic member 10 includes but is not limited to a spring, a U-shaped spring sheet or an elastic body of other shapes. It can be understood that the elastic force detection device is applicable to elastic force detection of elastic bodies of various shapes.

The first controller can receive data detected by the pressure sensor 120 and display the data through the first display screen 111 .

[0049] In this embodiment, in order to adapt to elastic members 10 of various shapes and sizes, the carrier 200 is replaceable, and different carriers 200 have different weights. In order to ensure the accuracy of the reading of the first display screen 111, the first controller can be electrically connected to a first zero key (not shown), and the first zero key can clear the pressure value displayed on the first display screen 111. The first zero key and the first display screen 111 can be arranged on the same side of the detection platform 110, for example, the front side of the detection platform 110.

The first switch key may turn on the first controller. The first controller may include but is not limited to a programmable logic controller (PLC) or a single-chip microcomputer.

[0051] In this embodiment, continue to refer to Figure 1 and Figure 2 As shown, the driving member 300 may include a push rod portion 310 and a driving portion 320, wherein the push rod portion 310 abuts against one end of the pressure rod 130 away from the detection platform 110; the driving portion 320 is connected to the push rod portion 310, and the driving portion 320 is used to drive the push rod portion 310 to move along the first direction. In this embodiment, the push rod portion 310 is driven by the driving portion 320 to move, so that the push rod portion 310 pushes against the pressure rod 130, and then the pressure rod 130 squeezes the elastic member 10, and the displacement of the push rod portion 310 is the displacement of the pressure rod 130, which can ensure the displacement accuracy of the pressure rod 130, that is, ensure that the displacement of the pressure rod 130 remains consistent, thereby ensuring the data accuracy detected by the pressure sensor 120.

[0052] Exemplarily, the driving member 300 includes but is not limited to a linear cylinder or an electric push rod.

[0053] Exemplarily, when the driving member 300 is a linear cylinder, the driving portion 320 is a cylinder body of the linear cylinder, and the push rod portion 310 is a telescopic rod of the linear cylinder.

[0054] Exemplarily, the driving unit 320 may also be an electric slide module, a linear motor or other driving devices.

[0055] In this embodiment, continue to refer to Figure 1 and Figure 2 As shown, the elastic force detection device further includes a second controller 400, and the second controller 400 is used to control the action of the driving member 300. When the driving member 300 is a linear cylinder, the second controller 400 can control the action of the driving member 300 through a solenoid valve. The second controller 400 can include but is not limited to a programmable logic controller or a single-chip microcomputer. Specifically, an action button (not shown) can be provided on the second controller 400, and the action of the driving member 300 can be controlled by the action button.

[0056] In this embodiment, continue to refer to Figure 1 and Figure 2As shown, the elastic force detection device also includes a displacement sensor 500, and the displacement sensor 500 is used to detect the displacement of the push rod part 310 along the first direction. Among them, the displacement sensor 500 can be arranged on the driving part 320. Of course, the displacement sensor 500 can also be arranged on other components of the elastic force detection device, and this application does not limit it. In this embodiment, through the arrangement of the displacement sensor 500, the driving part 320 can drive the push rod to move quantitatively along the first direction to ensure that the movement amount of the push rod part 310 during each detection remains consistent, thereby ensuring the displacement accuracy of the pressure rod 130. In addition, the displacement sensor 500 detects the displacement of the push rod part 310 along the first direction, and the displacement of the pressure rod 130 along the first direction can be obtained, thereby obtaining the extrusion amount of the elastic member 10. By analyzing the relationship between the extrusion amount of the elastic member 10 and the elastic force of the elastic member 10, the performance of the elastic member 10 can be better analyzed. In addition, by disposing the displacement sensor 500 , the driving member 300 can be set to drive the pressing rod 130 to move a constant displacement, that is, to press down the elastic member 10 in a quantitative manner, so as to detect the performance of the elastic member 10 .

[0057] Exemplarily, the displacement sensor 500 includes, but is not limited to, a pull-wire displacement sensor 500 or an electronic ruler.

[0058] Specifically, the second controller 400 may be electrically connected to the displacement sensor 500 . A second display screen 410 is disposed on the second controller 400 . The second controller 400 may receive the displacement detected by the displacement sensor 500 and display it through the second display screen 410 .

[0059] More specifically, the second controller 400 may also be provided with a second zeroing key (not shown), and the second zeroing key may clear the displacement displayed on the second display screen 410. Exemplarily, when the driving member 300 drives the pressure rod 130 to abut against the carrier 200, the displacement displayed on the second display screen 410 may be cleared by the second zeroing key to facilitate setting the downward displacement of the elastic member 10. The downward displacement of the elastic member 10 refers to the deformation amount of the elastic member 10 squeezed in the first direction by the pressure rod 130. It can be understood that setting the downward displacement of the elastic member 10, that is, setting the displacement amount of the driving member 300 to drive the pressure rod 130 to move to the extreme position required to measure the elastic force of the elastic member 10, can better ensure that the extreme position of the movement of the pressure rod 130 remains consistent by clearing the displacement displayed on the second display screen 410.

[0060] Of course, the second controller 400 may also be provided with a second switch key (not shown) and other function keys, which are not limited in this application. Among them, the second switch key can turn on the second controller 400.

In this embodiment, the support frame 600 is connected to the fixed shaft 140 in a threaded connection manner through the connecting sleeve 610, so as to facilitate the adjustment of the position of the support frame 600 along the first direction, so that the driving member 300 is suitable for driving the pressure rod 130 to squeeze the elastic member 10 along the first direction, so as to complete the detection of the elastic member 10.

The driving part 320 is sandwiched between the two support plates 630, which effectively ensures that the position of the driving part 320 relative to the support frame 600 is stable and reliable.

[0064] Specifically, the spring force measuring assembly 100 also includes a connecting seat 150 and a hand crank 160 rotatably arranged on the connecting seat 150, the connecting seat 150 is sleeved on the fixed shaft 140 and is threadedly connected to the fixed shaft 140, the pressure rod 130 is slidably penetrated through the connecting seat 150, the hand crank includes a rotating shaft 161 extending along the second direction and a pull rod 162 connected to the rotating shaft 161, and the rotating shaft 161 can be connected to the pressure rod 130 for transmission by means of gear rack meshing.

Among them, the elastic reset member can be a tension spring, a torsion spring or other elastic body.

[0065] Specifically, the connecting seat 150 may be provided with a digital scale 170, which includes a scale frame 171 provided on the connecting seat 150 and a scale body 172 slidably passing through the scale frame 171, the scale body 172 being connected to the pressure rod 130 and moving with the pressure rod 130, and a third display screen 173 being provided on the scale frame 171, the third display screen 173 being able to display the displacement of the scale body 172.

[0066] Of course, the ruler frame 171 may also be provided with a unit conversion key (not shown) or other function keys, which is not limited in this application.

[0067] In a feasible embodiment, a pressure head 131 is detachably connected to one end of the pressure rod 130 close to the carrier 200, and the pressure rod 130 can squeeze the elastic member 10 along the first direction through the pressure head 131 to avoid position interference between the pressure rod 130 and the carrier 200. And the pressure head 131 is detachably arranged on the pressure rod 130, and by replacing the pressure head 131, the elastic force detection device can be applied to the detection of elastic members 10 of various shapes and sizes. Exemplarily, the pressure head 131 can be connected to the pressure rod 130 by magnetic attraction, which is convenient for disassembly and assembly. Of course, the pressure head 131 can also be connected to the pressure rod 130 by threaded fastening or other methods, which is not limited in this application.

[0068] Exemplarily, a connecting plate 132 is provided at one end of the pressure rod 130 close to the carrier 200, and a connecting block 133 is provided on one side of the connecting plate 132 close to the carrier 200. A mounting hole is provided on the connecting block 133, and the pressure head 131 is inserted into the mounting hole. Among them, the connecting block 133 is provided on one end of the connecting plate 132 protruding from the connecting seat 150 along the third direction, so as to facilitate the disassembly and assembly of the pressure head 131.

In some embodiments, the connecting block 133 and the pressure head 131 can be fixed as a whole, and at least one of the connecting block 133 and the connecting plate 132 is provided with a magnetic suction part.

[0069] In this embodiment, refer to Figures 3 to 6As shown, the carrier 200 includes a support block 210 and a stopper 220, wherein the support block 210 is arranged on the pressure sensor 120, and the support block 210 is provided with a stopper surface 2111, a first side surface 2112 and a second side surface 2113 which are connected to each other, the stopper surface 2111 is perpendicular to the first side surface 2112 and the second side surface 2113, and the first side surface 2112 and the second side surface 2113 are arranged at an angle; the stopper 220 is arranged on the stopper surface 2111, and a space for stopping the elastic member 10 is formed between the stopper 220, the stopper surface 2111, the first side surface 2112 and the second side surface 2113. In this embodiment, the support block 210 and the stopper 220 are designed in a split type, which is convenient for processing and assembly, and adjusting the position of the support block 210 can make the carrier 200 suitable for stopping elastic members 10 of various sizes. Among them, the pressure head 131 is arranged at one end of the pressure rod 130 close to the support block 210.

[0070] Exemplarily, the U-shaped spring piece includes a U-shaped bottom 11 and two spring pieces 12 connected to the U-shaped bottom 11, the ends of the two spring pieces 12 abut against the first side 2112, and the end of one of the spring pieces 12 also abuts against the limiting surface 2111, one side edge of the two spring pieces 12 abuts against the second side 2113, and the U-shaped bottom 11 abuts against the limiting member 220, thereby realizing the limiting of the U-shaped spring piece by the carrier 200, effectively preventing the U-shaped spring piece from displacement deviation, non-working deformation, etc. during elastic force detection, and ensuring the accuracy of the detection data. Among them, the pressure head 131 squeezes the end of the spring piece 12 close to itself, causing the U-shaped spring piece to undergo elastic deformation, thereby achieving the purpose of elastic force detection.

[0071] Exemplarily, the material of the support block 210 and the limiting member 220 includes but is not limited to aluminum alloy.

[0072] In a feasible implementation, the limiting member 220 is rotatably disposed on the limiting surface 2111. Exemplarily, the limiting member 220 is in the shape of an elongated strip, one end of the limiting member 220 is rotatably connected to the support block 210, the limiting member 220 can rotate relative to the support block 210 around a first direction, and the side of the limiting member 220 close to the first side surface 2112 is used to limit the elastic member 10. Exemplarily, first, the limiting member 220 is rotated in a direction away from the first side surface 2112 to form a gap, and then the elastic member 10 is pressed against the limiting surface 2111, the first side surface 2112 and the second side surface 2113, and finally the limiting member 220 is reset to limit the elastic member 10 on the carrier 200, so as to facilitate the placement of elastic members 10 of different sizes. Among them, the limiting member 220 can fit the limiting surface 2111. Of course, the limiting member 220 can be slidably disposed on the limiting surface 2111 or be disposed on the limiting surface 2111 in other connection ways, and this application does not make any limitation thereto.

[0073] Exemplarily, the surface roughness Ra of the limiting surface 2111, the first side surface 2112 and the second side surface 2113 is less than 0.8, which reduces the detection error caused by the friction between the elastic member 10 and the first side surface 2112 and the second side surface 2113, reduces the friction between the limiting member 220 and the limiting surface 2111, and allows the limiting member 220 to move freely, which facilitates the replacement of the elastic member 10. It is understandable that when the elastic member 10 undergoes elastic deformation, the elastic member 10 will squeeze the limiting member 220. By reducing the surface roughness, the friction when the limiting member 220 rotates or moves to make way for the elastic member 10 is reduced to affect the detection data.

[0074] In a feasible implementation, a clearance groove 212 is provided on the first side surface 2112, and the pressing head 131 can penetrate the clearance groove 212 and abut against the elastic member 10 to ensure that the pressing head 131 and the elastic member 10 are abutted stably and reliably, and prevent the pressing head 131 from being separated from the elastic member 10, and prevent the pressing head 131 from interfering with the carrier 200. Taking the U-shaped spring sheet as an example, the end of the spring sheet 12 is placed toward the clearance groove 212.

[0075] In a feasible implementation, a positioning groove 213 is provided on one side of the support block 210 close to the detection platform 110, and the pressure sensor 120 is arranged in the positioning groove 213 and abuts against the bottom of the positioning groove 213, so as to facilitate the positioning and assembly of the support block 210 relative to the pressure sensor 120. The positioning groove 213 and the pressure sensor 120 can be matched with the shaft hole clearance. The support block 210 and the detection platform 110 are spaced apart, that is, the support block 210 and the detection platform 110 do not contact each other, so as to ensure that the data detected by the pressure sensor 120 is accurate.

[0076] In this embodiment, the elastic force detection device can be connected to a host computer, and the host computer can collect and analyze data information received by the first controller, the second controller 400 and the digital display scale 170, and the elastic force detection device can be controlled by the host computer to perform elastic force detection.

[0077] It is understandable that for connection methods not explicitly described in the text, common connection methods such as threaded connection, welding or bonding can be selected according to needs.

[0078] Exemplarily, the method for using the elastic force detection device specifically includes the following steps:

[0079] S100 , clearing the pressure value on the first display screen 111 , the displacement value on the third display screen 173 , and the displacement value on the second display screen 410 , and setting the downward displacement of the elastic member 10 .

[0080] Specifically, step S100 includes the following steps:

[0081] S110, installing the carrier 200 on the pressure sensor 120, turning on the first display screen 111 and the first controller through the first switch key, and clearing the pressure value displayed on the first display screen 111 through the first zero key.
