Description

Technical Field

[0001] This utility model belongs to the field of force gauge technology, and specifically relates to a force gauge calibration device. Background Technology

[0002] A force gauge is an instrument used to measure the magnitude of force. Its basic principle is to convert the force applied to it into a quantifiable physical quantity. The force acts on the sensor, causing a tiny elastic body inside the sensor to deform. The resistance value of the strain gauge attached to the elastic body changes accordingly. This change in resistance is converted into a weak voltage change through a Wheatstone bridge circuit, and after signal amplification and analog-to-digital conversion, the force value is finally displayed on the screen.

[0003] In existing technologies, the measuring ends of a standard force gauge and the force gauge to be tested are generally connected. Then, the standard force gauge is pulled, and the readings on the two sets of force gauges are recorded to calibrate the force gauge to be tested. However, when calibrating between the standard force gauge and the force gauge to be tested, it is easy for them to tilt or vibrate during the force application process, which can easily affect the calibration data and reduce the accuracy of the calibration results. Utility Model Content

[0004] To address the problem that during the calibration of a standard force gauge and the force gauge under test, the gauge is prone to tilting or vibrating during the force application process, which can easily affect the calibration data and reduce the accuracy of the calibration results, this utility model proposes a force gauge calibration device to overcome the above-mentioned technical problems existing in the existing related technologies.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model is a force gauge calibration device, including a base plate:

[0007] The base plate is equipped with positioning components, lifting components, adjustment components, and clamping components.

[0008] The positioning component is rotatably configured to limit the position of the lifting component.

[0009] The lifting component has one side fixedly connected to one side of the adjusting component, so that the lifting component can drive the adjusting component to move up and down;

[0010] An adjusting component, the top of which is fixedly connected to the bottom of the clamping component, so that the adjusting component can adjust the position of the clamping component.

[0011] Furthermore, the positioning component includes a support rod, the bottom end of which is fixedly installed to the top end of the base plate, and a positioning plate is fixedly installed on the top end of the support rod.

[0012] Furthermore, the lifting assembly includes a threaded rod, the outer surface of which is rotatably connected to the interior of the positioning plate, a handle fixedly installed at the top of the threaded rod, a limit plate rotatably connected to the outer surface of the threaded rod, and the bottom end of the limit plate fixedly installed to the top of the base plate.

[0013] The threaded surface of the threaded rod is connected to a lifting plate, and the interior of the lifting plate is slidably set with the outer surface of the support rod.

[0014] Furthermore, the adjustment assembly includes two sets of U-shaped frames, one side of which is fixedly connected to one side of the limiting plate and the lifting plate, respectively. A lead screw is rotatably installed inside the U-shaped frame, and a knob is fixedly installed at one end of the lead screw. An adjustment block is threadedly connected to the threaded surface of the lead screw.

[0015] Furthermore, the clamping assembly includes a guide groove, which is formed inside the U-shaped frame. A guide block is slidably disposed inside the guide groove. A mounting block is fixedly connected to one side of the guide block, and the bottom end of the mounting block is fixedly connected to the top end of the adjusting block.

[0016] Furthermore, the clamping assembly also includes a mounting groove, which is opened inside the mounting block. A positioning rod is fixedly connected to the inner wall of the mounting groove, and two sets of clamping blocks are slidably arranged on the outer surface of the positioning rod. A spring is fixedly connected to one side of the clamping block, and one end of the spring is fixedly connected to the inner wall of the mounting groove. A lever is fixedly connected to the top of each set of clamping blocks.

[0017] Furthermore, a sliding rod is fixedly connected to one side of the U-shaped frame, and a support block is slidably connected to the outer surface of the sliding rod. The top of the support block is fixedly connected to the bottom of the mounting block.

[0018] This utility model has the following beneficial effects:

[0019] 1. This utility model symmetrically clamps and fixes a standard force gauge and a force gauge to be tested inside two sets of clamping components. Then, the measuring ends of the standard force gauge and the force gauge to be tested are connected. Then, the two sets of adjusting components fixed to the bottom of the two sets of clamping components are rotated so that the adjusting components cooperate with the clamping components to move the standard force gauge and the force gauge to be tested. This facilitates the adjustment of their positions and keeps them in a horizontal state, thereby avoiding the standard force gauge and the force gauge to be tested from shifting and shaking during the verification process, thus improving the accuracy of the verification results.

[0020] 2. This utility model rotates a knob to drive a lead screw installed on one side to rotate, so that the lead screw drives an adjusting block connected by a threaded surface to move along the inner wall of the U-shaped frame. This allows the adjusting block to drive a mounting block fixed at the top to move, so that the mounting block, in conjunction with the mounting groove inside, drives a positioning rod to move. This, in turn, causes the positioning rod to drive a clamping block that is slidably set on the outer surface to move, so that the clamping block can move the standard force gauge and the force gauge to be measured that are clamped and fixed inside, and keep the standard force gauge and the force gauge to be measured in a horizontal state.

[0021] Of course, any product implementing this utility model does not necessarily need to achieve all of the above advantages at the same time. Attached Figure Description

[0031] The technical solutions of the utility model embodiments will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the utility model, and not all embodiments. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the utility model.

[0032] In the description of this utility model, it should be understood that the terms "opening", "upper", "lower", "top", "middle", "inner", etc., which indicate orientation or positional relationship, are only for the convenience of describing the utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the utility model.

[0033] Please see Figures 1-6 As shown, this utility model is a force gauge calibration device, including a base plate 1:

[0034] The base plate 1 is respectively equipped with a positioning component 2, a lifting component 3, an adjusting component 4, and a clamping component 5;

[0035] Positioning component 2 is rotatably configured to limit the position of lifting component 3.

[0036] The lifting component 3 is fixedly connected to one side of the adjusting component 4, so that the lifting component 3 can drive the adjusting component 4 to move up and down;

[0037] Adjustment component 4, the top end of which is fixedly connected to the bottom end of clamping component 5, so that adjustment component 4 can adjust the position of clamping component 5.

[0038] In use, the standard force gauge and the force gauge to be tested are symmetrically clamped and fixed inside the two sets of clamping components 5. Then, the measuring ends of the standard force gauge and the force gauge to be tested are connected. Then, the two sets of adjusting components 4, which are fixed to the bottom of the two sets of clamping components 5, are rotated to move the standard force gauge and the force gauge to be tested in conjunction with the clamping components 5. This facilitates the adjustment of their positions and keeps them horizontal. Then, the lifting component 3 is rotated so that the inside of the positioning component 2, which is rotated on its outer surface, is rotated around the center. This causes the lifting component 3 to move one of the sets of adjusting components 4 fixed on one side. This allows one set of adjusting components 4 to move the standard force gauge upward in conjunction with one set of clamping components 5. This allows the standard force gauge to work with the measuring end of the force gauge to be tested. When it reaches a fixed height, the readings on the standard force gauge and the force gauge to be tested are recorded to facilitate the calibration of the force gauge to be tested.

[0039] This invention symmetrically clamps and fixes a standard force gauge and a force gauge to be tested inside two sets of clamping components 5. Then, the measuring ends of the standard force gauge and the force gauge to be tested are connected. Next, the two sets of adjusting components 4, which are fixed to the bottom of the two sets of clamping components 5, are rotated so that the adjusting components 4 cooperate with the clamping components 5 to move the standard force gauge and the force gauge to be tested. This facilitates the adjustment of their positions and keeps them in a horizontal state, thereby avoiding the standard force gauge and the force gauge to be tested from shifting and shaking during the verification process, and thus improving the accuracy of the verification results.

[0040] In one embodiment, the positioning component 2 includes a support rod 201, the bottom end of which is fixedly installed with the top end of the base plate 1, and a positioning plate 202 is fixedly installed on the top end of the support rod 201.

[0041] Since there are two sets of support rods 201 arranged symmetrically, their top ends are fixedly installed with the bottom end of the positioning plate 202, thereby limiting the top ends of the two sets of support rods 201 by the positioning plate 202, thus improving the stability of the two sets of support rods 201.

[0042] In one embodiment, for the above-mentioned lifting assembly 3, the lifting assembly 3 includes a threaded rod 301, the outer surface of the threaded rod 301 is rotatably connected to the inside of the positioning plate 202, the top end of the threaded rod 301 is fixedly installed with a handle 302, the outer surface of the threaded rod 301 is rotatably connected to a limiting plate 303, and the bottom end of the limiting plate 303 is fixedly installed with the top end of the base plate 1.

[0043] The threaded surface of the threaded rod 301 is threadedly connected to a lifting plate 304, and the interior of the lifting plate 304 is slidably disposed with the outer surface of the support rod 201.

[0044] By rotating the handle 302, the threaded rod 301 installed at the bottom is driven to rotate. Since the threaded surface of the threaded rod 301 is connected to the internal thread of the lifting plate 304, and the interior of the lifting plate 304 is slidably disposed with the outer surface of the support rod 201, when the threaded rod 301 rotates, it can drive the lifting plate 304 to move up and down along the outer surface of the support rod 201. This restricts the movement direction of the lifting plate 304 by the support rod 201, thereby improving the stability of the lifting plate 304 during movement.

[0045] In one embodiment, the adjustment component 4 includes two sets of U-shaped frames 401. One side of each set of U-shaped frames 401 is fixedly connected to one side of the limiting plate 303 and the lifting plate 304, respectively. A lead screw 402 is rotatably provided inside the U-shaped frame 401. A knob 403 is fixedly installed at one end of the lead screw 402. An adjustment block 404 is threadedly connected to the threaded surface of the lead screw 402.

[0046] When the lifting plate 304 moves, it can drive one set of U-shaped frames 401 to move, so that one set of U-shaped frames 401 drives one set of screw rods 402 with internal rotation to move, so that one set of screw rods 402 drives one set of adjusting blocks 404 with threaded connection on the threaded surface to move.

[0047] By rotating the knob 403, the lead screw 402 installed on one side is rotated, so that the lead screw 402 drives the adjusting block 404 with the threaded connection on the threaded surface to move along the inner wall of the U-shaped frame 401, thereby facilitating the adjustment of the position of the adjusting block 404.

[0048] In one embodiment, the clamping assembly 5 includes a guide groove 501, which is formed inside the U-shaped frame 401. A guide block 502 is slidably disposed inside the guide groove 501. A mounting block 503 is fixedly connected to one side of the guide block 502. The bottom end of the mounting block 503 is fixedly connected to the top end of the adjusting block 404.

[0049] The clamping assembly 5 also includes a mounting groove 504, which is formed inside the mounting block 503. A positioning rod 505 is fixedly connected to the inner wall of the mounting groove 504. Two sets of clamping blocks 506 are slidably arranged on the outer surface of the positioning rod 505. A spring 507 is fixedly connected to one side of the clamping block 506. One end of the spring 507 is fixedly connected to the inner wall of the mounting groove 504. A lever 508 is fixedly connected to the top of each set of clamping blocks 506.

[0050] By pulling the lever 508, the clamping block 506 fixed at the bottom is moved. Then, the standard force gauge and the force gauge to be tested are placed inside the clamping block 506 respectively. The lever 508 is released so that the clamping block 506 can move in conjunction with the spring 507 fixed on one side to release the compressive stress, thereby clamping and fixing the standard force gauge and the force gauge to be tested.

[0051] When the adjusting block 404 moves with the rotation of the lead screw 402, it can drive the mounting block 503 fixed at the top to move, so that the mounting block 503 cooperates with the mounting groove 504 opened inside to drive the positioning rod 505 to move, so that the positioning rod 505 drives the clamping block 506 slidably set on the outer surface to move, so that the clamping block 506 can drive the standard force gauge and the force gauge to be measured, which are clamped and fixed inside, to move, and keep the standard force gauge and the force gauge to be measured in a horizontal state.

[0052] As one set of adjusting blocks 404 moves upward, it causes the mounting block 503 fixed at the top to move upward, thereby causing the mounting block 503 to move in conjunction with the mounting groove 504 to move the positioning rod 505. This allows the positioning rod 505 to move the clamping block 506, which in turn moves the standard force gauge away from the force gauge under test, thus facilitating the pulling verification of the standard force gauge and the force gauge under test.

[0053] In one embodiment, for the U-shaped frame 401 described above, a sliding rod 6 is fixedly connected to one side of the U-shaped frame 401, and a support block 7 is slidably connected to the outer surface of the sliding rod 6. The top end of the support block 7 is fixedly connected to the bottom end of the mounting block 503.

[0054] When the mounting block 503 moves along with the adjusting block 404, it can drive the support block 7 fixed at the bottom to move, so that the support block 7 moves along the direction of the sliding rod 6 that is slidably set inside. This makes it easier to restrict the movement direction of the mounting block 503 with the support block 7, and improves the stability of the mounting block 503 during the movement process.

[0055] Through the above technical solution, 1. By symmetrically clamping and fixing the standard force gauge and the force gauge to be tested inside the two sets of clamping components 5, and then connecting the measuring ends of the standard force gauge and the force gauge to be tested, the two sets of adjusting components 4 fixed to the bottom of the two sets of clamping components 5 are rotated so that the adjusting components 4 cooperate with the clamping components 5 to move the standard force gauge and the force gauge to be tested, thereby facilitating the adjustment of their positions and keeping them in a horizontal state, thereby avoiding the standard force gauge and the force gauge to be tested from shifting and shaking during the verification process, and thus improving the accuracy of the verification results;

[0056] 2. By rotating the knob 403, the lead screw 402 installed on one side is rotated, so that the lead screw 402 drives the adjusting block 404 connected by the threaded surface to move along the inner wall of the U-shaped frame 401. This allows the adjusting block 404 to drive the mounting block 503 fixed at the top to move, so that the mounting block 503, in conjunction with the mounting groove 504 opened inside, drives the positioning rod 505 to move. This causes the positioning rod 505 to drive the clamping block 506 slidably set on the outer surface to move, so that the clamping block 506 can drive the standard force gauge and the force gauge to be measured, which are clamped and fixed inside, to move and keep the standard force gauge and the force gauge to be measured in a horizontal state.
