A measuring instrument

Abstract

This utility model provides a measuring instrument, relating to the field of torque testing technology, comprising: a testing base; a torque sensor disposed on the top surface of the testing base; a lower clamp disposed on the top surface of the torque sensor; a lifting seat fixedly connected to the center of the rear part of the top surface of the testing base; an upper clamp slidably connected inside the lifting seat; the upper clamp and the lower clamp being aligned; two mounting brackets symmetrically fixedly connected to the outside of the lower clamp; a first rotating shaft rotatably connected inside each of the two mounting brackets; and a second rotating shaft rotatably connected inside each of the two mounting brackets. During the clamping and fixing of the liquor bottle, the liquor bottle will squeeze the control slide, and then through a series of transmissions, the swing frame will rotate, causing the clamping frame to clamp and fix the middle of the bottle. This solves the problem that when torque is applied to the bottom of the bottle, a lever effect is formed with the bottom of the bottle as the fulcrum and the bottle body as the lever arm, causing the bottle body to wobble due to the shift of the center of gravity.

Description

Technical Field

[0001] This utility model relates to the field of torque testing technology, and in particular to a measuring instrument. Background Technology

[0002] In the process of producing baijiu, since baijiu needs to be stored in a sealed environment to prevent alcohol evaporation, in order to ensure the sealing effect of the baijiu bottle and prevent the liquor from deteriorating, a measuring instrument is usually used to detect the torque of the baijiu bottle cap. Existing measuring instruments usually consist of a base, a lower clamp, an upper clamp and a torque sensor.

[0003] For example, utility model application CN202121533454.7 discloses a bottle cap torque measuring instrument. Specifically, this application relates to a bottle cap torque measuring instrument, belonging to the field of torque testing instruments. It includes a base, a support frame on the base, a torque sensor rotatably connected to the base, a first clamp on the torque sensor for holding a bottle body or bottle cap, and a second clamp on the support frame for holding a bottle body or bottle cap. This application improves the accuracy and convenience of detecting the seal between the bottle body and bottle cap.

[0004] However, in the current traditional metrology and testing instruments, when performing torque testing on liquor bottle caps, the bottom of the liquor bottle is usually clamped and fixed by a lower clamp. This causes the center of gravity of the bottle body and cap to be located above the bottom of the bottle. When the torque sensor drives the lower clamp to rotate and applies torque to the bottom of the bottle, a lever effect is formed with the bottom of the bottle as the fulcrum and the bottle body as the lever arm. This causes the bottle body to shake due to the shift in the center of gravity, which not only interferes with the stability of the testing process but also affects the accuracy of the cap torque test results, making it quite inconvenient to use. Utility Model Content

[0005] In view of this, the present invention provides a measuring and testing instrument, which has a clamping frame that can ensure the stability of the testing process. During the clamping and fixing of the liquor bottle, the liquor bottle will squeeze the control slide, causing the control slide to slide within the mounting frame and squeeze the connecting spring. As the control slide slides, it will drive the transmission rack to move. As the transmission rack moves, it will drive the transmission gear meshing with it to rotate. As the transmission gear rotates, it will drive the first rotating shaft to rotate. During the rotation of the first rotating shaft, it will drive the first bevel gear to rotate. As the first bevel gear rotates, it will drive the second bevel gear meshing with it to rotate. As the second bevel gear rotates, it will drive the transmission worm to rotate. As the transmission worm rotates, it will drive the transmission worm wheel to rotate. As the transmission worm wheel rotates, it will drive the second rotating shaft to rotate. As the second rotating shaft rotates, it will drive the swing frame to rotate, so that the clamping frame clamps and fixes the middle part of the bottle.

[0006] This utility model provides a measuring instrument, specifically comprising: a measuring base; a torque sensor disposed on the top surface of the measuring base; a lower clamp disposed on the top surface of the torque sensor; a lifting seat fixedly connected to the center of the rear part of the top surface of the measuring base; an upper clamp slidably connected inside the lifting seat; the upper clamp and the lower clamp being aligned; two mounting brackets symmetrically fixedly connected to the outside of the lower clamp; a first rotating shaft rotatably connected inside each of the two mounting brackets; a second rotating shaft rotatably connected inside each of the two mounting brackets; the two second rotating shafts being respectively disposed outside the two first rotating shafts; a swing frame coaxially fixedly connected to the outside of each of the two second rotating shafts; and a clamping frame fixedly connected to the outside of each of the two swing frames.

[0008] Optionally, a control motor is bolted to the top surface of the lifting seat; a lifting screw is coaxially fixed to the bottom surface of the control motor shaft; the lifting screw is rotatably connected inside the lifting seat; and the upper clamp is threaded to the outside of the lifting screw.

[0009] Optionally, a second drive motor is bolted to the left end face of the upper clamp; a second double-ended screw is coaxially fixed to the outside of the shaft of the second drive motor; the threads at both ends of the second double-ended screw have opposite directions; two upper clamping plates are symmetrically threaded to the outside of the second double-ended screw; a set of second mounting threaded holes are opened on the bottom end face of both upper clamping plates; a set of upper clamping posts are threaded into both sets of second mounting threaded holes.

Beneficial effects

[0012] This invention, during the clamping and fixing of a liquor bottle, causes the bottle to press against a control slide. As the control slide slides, it moves a transmission rack, which in turn rotates a meshing transmission gear. This rotation, through a series of transmissions, causes a transmission worm gear to rotate, which in turn rotates a transmission worm wheel. The rotation of the worm wheel, in turn, rotates a second rotating shaft, which in turn rotates a swing frame. This clamping mechanism secures the bottle to the center, increasing the contact area between the lower clamp and the bottle, resulting in more even force distribution, a shorter torque transmission path, a stable center of gravity, and significantly improved stability. It reduces the likelihood of wobbling due to torque, effectively ensuring the accuracy of the liquor bottle cap torque detection. The invention is also more convenient to use and improves the practicality of the measuring instrument. Attached Figure Description
