Description

Technical Field

[0001] This utility model relates to the technical field of calibration devices, and in particular to a force measuring instrument calibration device. Background Technology

[0002] A force gauge is a portable measuring instrument used to measure various force values ​​or loads. It is also called a force meter and has various classifications. According to the object of use, it is divided into working force gauges and standard force gauges. The main indicators for evaluating the accuracy level of a force gauge are repeatability and stability. It is often necessary to calibrate it before leaving the factory or when the value deviates. A force gauge calibration device, as disclosed in prior art publication number CN212110454U, includes a base and a fixing device. A hydraulic jack a is fixedly installed on the upper left side of the base, and a hydraulic jack b is fixedly installed on the right side. A connecting block a is fixedly installed at the top of hydraulic jack a, and a connecting block b is fixedly installed at the top of hydraulic jack b. A crossbeam is fixedly connected between connecting block a and connecting block b. A mounting plate is fixedly installed at the lower end of the crossbeam, and an upper fixing clamp is fixedly installed at the lower end of the mounting plate. Two fixing plates are fixedly installed at the middle of the upper end of the base. One end of a bolt is fixedly installed with the lower fixing clamp, and a test force gauge is provided inside the lower fixing clamp. This force gauge calibration device connects a standard force gauge and a test force gauge using a tension rod. By manually controlling the hydraulic jack to move the standard force gauge upwards, a pulling force is generated between them. The force gauge is calibrated based on the measured value, and the overall process is convenient for recording and analysis. However, the distance adjustment is not convenient enough, the measurement is not accurate enough, and only one standard force gauge can be tested and calibrated at a time, resulting in low testing and calibration efficiency. Utility Model Content

[0003] To solve the above-mentioned technical problems, this utility model provides a force measuring instrument calibration device that can test multiple instruments at one time, which is beneficial to improving work efficiency, providing stable fixation, and facilitating disassembly and maintenance.

[0004] This utility model discloses a force measuring instrument calibration device, comprising a base, a fixing component, a lifting component, and a calibration component. The fixing component is installed on the top of the base, and the lifting components are installed on the left and right ends of the top of the base. The calibration component is installed on the lifting components. The fixing component facilitates the installation and fixing of the force measuring instrument, making it convenient to use and enabling the simultaneous testing of multiple instruments, which helps to improve work efficiency. At the same time, the height of the calibration component can be adjusted by the lifting component, which facilitates the adjustment of the distance between the calibration component and the force measuring instrument, ensuring stable fixation and convenient disassembly and maintenance.

[0005] Preferably, the fixing assembly includes a servo motor, a threaded rod, a movable seat, a fixing frame, and an insert rod. A sliding groove is provided at the front end of the base, and the threaded rod is rotatably installed within the sliding groove. The input end of the threaded rod is connected to the output end of the servo motor. The movable seat is slidably installed within the sliding groove, and its middle portion is screwed onto the outer wall of the threaded rod. Multiple fixing grooves are provided at the top of the movable seat. The fixing frame is installed on the rear side of the top of the base, and an insert rod is installed at the front end of the fixing frame. A fixing insertion hole is provided on the movable seat, and the insert rod is slidably inserted into the fixing insertion hole. The lower fixing hook of the force gauge is placed into the fixing groove, and the servo motor is started to drive the threaded rod to rotate, causing the movable seat to slide backward within the sliding groove. Simultaneously, the insert rod is inserted into the fixing insertion hole, connecting the force gauge and ensuring its stable fixation. This design facilitates disassembly and maintenance, enabling the simultaneous testing of multiple instruments and improving work efficiency.

[0006] Preferably, it also includes two supporting slide rods and two guide sliders. The supporting slide rods are symmetrically installed at the left and right ends of the sliding groove, and the left and right ends of the movable seat are slidably installed on the supporting slide rods. Guide grooves are opened at the left and right ends of the sliding groove, and guide sliders are installed at the left and right ends of the movable seat. The guide sliders are slidably installed in the guide grooves. When the movable seat moves, it slides on the supporting slide rods and simultaneously drives the guide sliders to slide in the guide grooves, thereby enhancing the structural strength and ensuring the stability during movement.

[0007] Preferably, the lifting assembly includes two support frames, two sets of electric telescopic rods, two push plates, and a top plate. The two support frames are installed at the left and right ends of the top of the base, and the two sets of electric telescopic rods are respectively located at the left and right ends of the top of the base. The top of the electric telescopic rods is connected to the support frames, and a push plate is installed at the top telescopic end of the electric telescopic rod. The top plate is installed between the two push plates. In use, the height of the top plate can be adjusted by using the electric telescopic rods and push plates to facilitate adjustment of the distance between the top plate and the force measuring instrument. When the top plate rises, it pulls the fixed hook on the force measuring instrument, which can test the error of the force measuring instrument, improve calibration efficiency, and facilitate recording and analysis.

[0008] Preferably, the calibration assembly includes multiple fixed seats, multiple fixing screws, multiple connecting rods, multiple tension rods, a standard force gauge, and multiple limiting guide rods. The multiple fixed seats are evenly installed on the top of the top plate. Each fixed seat has a mounting groove at its bottom corresponding to a fixing groove. The connecting rods are installed in the mounting grooves via fixing screws. A tension rod is connected to the bottom of each fixing screw. A standard force gauge is installed at the bottom of the middle connecting rod. A connecting frame is installed at the bottom of the tension rod and the standard force gauge. The connecting frame connects to the fixed hook on the test force gauge. When the top plate moves upward, the test force gauge is pulled by the connecting rods and tension rods, causing the fixed hook of the test force gauge to experience the same tension, and pulling the standard force gauge. The tension experienced by the standard force gauge and the test force gauge is equal. By comparing the readings of the standard force gauge and the test force gauge, the error of the test force gauge can be measured.

[0009] Preferably, it also includes two limiting guide rods, which are respectively installed at the middle of the bottom end of the push plate. The limiting guide rods are slidably installed in the middle of the support frame, and scale lines are provided on the outer wall of the limiting guide rods. When the push plate moves upward, it drives the limiting guide rods to slide on the support frame, thereby limiting and guiding them, enhancing the structural strength, ensuring stability, and ensuring that the scale lines can ensure that the two ends of the top plate are on the same horizontal plane, making the measurement more accurate.

[0010] Compared with the prior art, the advantages of this utility model are as follows: the fixing component is convenient for installing and fixing the test force measuring instrument, which is convenient to use and can test multiple instruments at one time, which helps to improve work efficiency. At the same time, the height of the calibration component can be adjusted by the lifting component, which makes it easy to adjust the distance between the calibration component and the test force measuring instrument, which is stable and convenient for disassembly and maintenance.

The top plate 12 is connected to the fixed hook on the test force measuring instrument via the connecting frame 18.
