Referring to fig. 1, the present embodiment provides a height gauge comprising a platform 1, a trailing arm 2, a cross arm 3 and a gauge 4. The platform 1 made of marble is used for placing a product to be tested; the trailing arm 2 is arranged on the platform 1, can move along a first direction and extends along a second direction; the cross arm 3 is arranged on the longitudinal arm 2, can move along the second direction and extends along the third direction; the gauge 4 is arranged on the cross arm 3 and can move along a third direction, and can be a dial indicator or a dial indicator and is used for detecting products. The gauge 4 is arranged on the platform 1 in turn by means of the cross arm 3 and the trailing arm 2, so that the height gauge is integrated with the platform 1 carrying the product.

Specifically, the first direction is perpendicular to the second direction and the third direction, and the second direction is perpendicular to the third direction, that is, the first direction, the second direction and the third direction are orthogonally distributed in space. The first direction and the third direction are horizontally arranged, and the second direction is vertically arranged.

After the trailing arm 2 moves to a proper position along the first guide rail 11, the positioning can be realized without a positioning device; after the gauge 4 is moved to a proper position along the third guide rail 31, the positioning can be realized without a positioning device. Wherein the platform 1 is parallel to the first rail 11 and the third rail 31, and perpendicular to the second rail 21, i.e. the platform 1 is horizontally disposed. If the tested product is provided with a base or can be directly and stably placed on a horizontal plane, the tested product can be directly placed on the platform 1 during detection.

Still referring to fig. 1, the slider 5 is disposed on each of the longitudinal arm 2, the lateral arm 3 and the scale 4, the slider 5 has a slide groove 50, and the first rail 11, the second rail 21 and the third rail 31 are respectively disposed in the slide groove 50 of the slider 5 slidably coupled thereto (see fig. 5), so that the engagement of the longitudinal arm 2 with the first rail 11, the engagement of the lateral arm 3 with the second rail 21 and the engagement of the scale 4 with the third rail 31 are stable.

referring to fig. 2, 3 and 4, the slide groove 50 has a protrusion a on a sidewall thereof; the first guide rail 11 is provided with a guide groove b extending along the length direction of the first guide rail 11; the second guide rail 21 is provided with a guide groove b extending along the length direction of the second guide rail 21; the third rail 31 is provided with a guide groove b extending in the longitudinal direction of the third rail 31. The protrusion a is arranged in the guide groove b and can slide along the guide groove b, so that the slider 5 is more tightly matched with the first guide rail 11, the second guide rail 21 and the third guide rail 31 and is not easy to fall off.

In the present embodiment, two first guide rails 11 are provided; the two ends of the first guide rail 11 are respectively provided with a first stopper 110 to prevent the slider 5 on the first guide rail 11 from falling off from the first guide rail 11.

in this embodiment, the bottom end of the trailing arm 2 is provided with a bottom plate 211, the upper surface of the bottom plate 211 is connected to the bottom end of the second guide rail 21, and the top end of the second guide rail 21 is provided with a second stopper 210 to prevent the slider 5 on the second guide rail 21 from falling off from the second guide rail 21; the lower surface of bottom plate 211 is connected with two sliders 5, through two sliders 5 and two first guide rail 11 sliding connection, two first guide rail 11 and two slider 5 one-to-one cooperation for trailing arm 2 is more stable and difficult crooked along the removal of first guide rail 11.

in the embodiment, one end of the cross arm 3 is connected with a slide block 5 through an angle plate 32, and is connected with the second guide rail 21 in a sliding way through the slide block 5; the two ends of the third rail 31 are respectively provided with a third stopper 310 to prevent the slider 5 on the third rail 31 from falling off from the third rail 31. Wherein the corner plate 32 has a first plate 321 and a second plate 322 connected perpendicularly to each other, the first plate 321 and the second plate 322 being disposed vertically.

The probe tube 41 is vertically arranged and detachably clamped between the first clamp body 401 and the second clamp body 402. Since the first clamp body 401 and the second clamp body 402 are made of elastic material, the probe tube 41 can move up and down relative to the elastic clamp 40 relatively easily, so that the position of the probe tube 41 in the vertical direction can be adjusted conveniently, and the probe tube 41 can be taken out from the elastic clamp 40 for replacement and maintenance.

A second set screw 403 is screwed on the first clamp body 401 or the second clamp body 402. By tightening the second set screw 403, the second set screw 403 is abutted against the probe tube 41 to position the probe tube 41 on the elastic clamp 40. The position of the probe tube 41 in the vertical direction is adjusted and positioned for further fine adjustment, provided that the cross arm 3 can move up and down along the second guide rail 21.

The detection method of the height gauge for the product is as follows:

first, the product is placed on the platform 1.

Next, the trailing arm 2 is adjusted to a proper position along the first guide rail 11.

Again, after the cross arm 3 is adjusted to a proper position along the second rail 21, the first set screw 323 is tightened to position.

the spring clip 40 is then adjusted to the proper position along the third rail 31 so that the gauge 4 is above the measured position of the product being measured.

Then, the probe tube 41 is moved up and down relative to the elastic clamp 40 to adjust the distance between the gauge 4 and the product to be measured until the probe 42 abuts against the position to be measured.

finally, the trailing arm 2 is adjusted along the first guide rail 11, and the elastic clamp 40 is adjusted along the third guide rail 31, so as to drive the probe 42 respectively along the first direction and the third direction, and detect each point position on the measured position; the deviation of each point position in the height direction is judged by observing the jump of the pointer of the meter 4.

The height direction is the second direction in the present embodiment.
