Description

Technical Field

[0001] This utility model relates to the field of height gauge calibration technology, and more specifically, to an auxiliary lifting device for height gauge calibration. Background Technology

[0002] A height caliper is a measuring tool used to measure the height of an object. It typically consists of a main body, a sliding slider, and a measuring scale. The main body is an upright metal rod with vertical graduations, usually in millimeters or inches, used to measure the object's height. The sliding slider is a movable component that can be adjusted up and down using a knob or handle. The slider usually also has graduations for reading its position relative to the main body. To ensure the accuracy of the height caliper's measurements, it needs to be calibrated periodically.

[0003] Traditional height gauge calibration devices require manual removal of a quantitative block from the box and placement on a desktop platform, followed by measurement by the caliper teeth to be calibrated. However, this traditional method requires manual placement of the quantitative block, which is prone to affecting the accuracy of the final measurement data due to wear or misalignment of the block.

[0027] Example 1 Please refer to Figure 1-6An auxiliary lifting device for height gauge calibration includes a base 1, with rubber pads 2 at each of the four corners of the base 1. A clamping assembly 3 is located inside the base 1. An adjusting assembly 4 is located on one side of the top of the base 1. Two third connecting rods 5 are fixedly connected to one side of the adjusting assembly 4. A second connecting plate 6 is fixedly installed at one end of each of the two third connecting rods 5. A calibration plate 7 is fixedly connected between the two second connecting plates 6. Pointers 8 are provided on the surfaces of the two third connecting rods 5. A positioning groove 9, which mates with the calibration plate 7, is provided on one side of the top of the base 1. The adjusting assembly 4 includes two mounting brackets 401, connected by a connecting pipe 402. A second adjusting knob 403 is provided on both sides of the connecting pipe 402. One side of each second adjusting knob 403 extends into the inner cavity of the connecting pipe 402 and is fixedly connected to a second connecting rod 404. A second worm gear 405 is provided on both sides of the surface of the second connecting rod 404. A lead screw 406 is movably connected to the inner cavity of the two mounting brackets 401. A collar turbine 407 is provided at the bottom of the surface of the lead screw 406, meshing with the second worm gear 405. A movable block 408 is movably connected to the surface of the lead screw 406. One side of the movable block 408 is fixedly connected to a third connecting rod 5. A second limiting groove 409 is provided on both sides of the mounting bracket 401 to mate with the movable block 408. Multiple scale marks 410 mate with the pointer 8 are provided on one side of each of the two mounting brackets 401.

[0028] During implementation, the base 1 of the device is stably placed by the rubber pads 2 at the four corners of the bottom, reducing vibration and slippage during operation. When the height gauge needs to be calibrated, the height of the calibration plate 7 is adjusted by adjusting the component 4 to meet the calibration requirements. The operator turns the second adjustment knob 403, which drives the second connecting rod 404 and the second worm gear 405 on the surface to rotate. The second worm gear 405 meshes with the collar turbine 407, causing the collar turbine 407 to drive the lead screw 406 to rotate within the mounting bracket 401. When the lead screw 406 rotates, the movable block 408 on the surface is restrained by the second limiting groove 409. Moving up and down along the lead screw 406, the movable block 408 drives the third connecting rod 5, the second connecting plate 6, and the calibration plate 7 to rise and fall synchronously. During the adjustment process, the pointer 8 on the surface of the third connecting rod 5 moves along with it. The lifting height of the calibration plate 7 can be read intuitively through the scale 410 on one side of the mounting bracket 401, ensuring that the calibration plate 7 reaches the required calibration position. At the same time, the positioning groove 9 on the top of the base 1 places and positions the initial position of the calibration plate 7 to ensure the accuracy of the calibration benchmark. Finally, the height gauge is used to correspond with the calibration plates 7 at different height positions to complete the height gauge calibration work.

[0029] Example 2 The clamping assembly 3 includes two first adjustment knobs 301, which are respectively disposed on both sides of the base 1. One side of each first adjustment knob 301 extends into the inner cavity of the base 1 and is fixedly connected to a first worm gear 302. First connecting blocks 303 are provided on both sides of the surface of the first worm gear 302, and the first connecting blocks 303 are fixedly connected to the inner cavity of the base 1. One side of the first worm gear 302 engages with a first worm wheel 304, and the inner cavity of the first worm wheel 304 is fixedly connected to a first connecting... The first connecting rod 305 has two ends movably connected to the inner cavity of the base 1. A first connecting plate 306 is movably connected to the surface of the first connecting rod 305, and the first connecting plate 306 is fixedly connected to the inner cavity of the base 1. A drive gear 307 is provided on the surface of the first connecting rod 305, and toothed plates 308 mesh with both sides of the drive gear 307. A fixing block 309 is fixedly installed on one side of the top of the toothed plate 308, and the fixing block 309 extends through to the top of the base 1 and is fixedly connected to a clamping plate 310. A first limiting groove 311 is provided on one side of the toothed plate 308, and a limiting rod 312 is slidably connected to the inner cavity of the first limiting groove 311. The limiting rod 312 is fixedly connected to the top of the first connecting plate 306. A protective cotton 313 is provided on one side of the clamping plate 310.

[0030] During the implementation process, when the height gauge needs to be calibrated, the height gauge is first fixed using the clamping assembly 3. The operator rotates the first adjustment knobs 301 on both sides of the base 1, which drives the first worm gear 302 to rotate. The first worm gear 302 meshes with the first worm wheel 304, causing the first worm wheel 304 to drive the first connecting rod 305 to rotate, which in turn causes the drive gear 307 on the surface of the first connecting rod 305 to rotate. The drive gear 307 meshes with the toothed plates 308 on both sides. Under the guidance of the limiting rod 312, the first limiting groove 311 drives the toothed plates 308 to move back and forth. The toothed plates 308 drive the fixing block 309 and the clamping plate 310 to move relative to each other. The protective cotton 313 on one side of the clamping plate 310 firmly clamps the height gauge on the base 1 to prevent displacement during the calibration process.
