Description

Direct-reading type nozzle outer diameter measuring tool

Technical Field

The utility model relates to a measure utensil technical field, concretely relates to novel direct-reading type mouth of a river external diameter measuring tool.

Background

The erosion of continuous casting refractory materials is one of the major concerns of continuous casting, the erosion degree of a continuous casting water gap is always concerned by continuous casting workers, the outer diameter of the eroded water gap is irregular, and the erosion degree cannot be directly measured by using a traditional measuring tool. The existing measuring method is to use a caliper to clamp a water gap slag line part, then the caliper is moved out, and the size of an opening of the caliper is measured to be the outer diameter of the water gap, but a measurer moves out the caliper and then measures the water gap with larger error.

SUMMERY OF THE UTILITY MODEL

The utility model aims to solve the technical problem that a novel direct-reading formula mouth of a river external diameter measuring tool is provided to above-mentioned prior art, and measurement process is simple and convenient, and measurement numerical value is more accurate.

The utility model provides a technical scheme that above-mentioned problem adopted does: the utility model provides a direct-reading formula mouth of a river external diameter measuring tool which characterized in that: the ruler comprises a ruler arm with scales, a first L-shaped clamping pin and a second L-shaped clamping pin, wherein the long arm end of the first L-shaped clamping pin is fixed at one end of the ruler arm through a bolt, and a zero scale mark is arranged on the ruler arm close to the first L-shaped clamping pin; the ruler arm is sleeved with a slidable sliding block, the long arm end part of the second L-shaped clamping pin is vertically connected to the sliding block through a screw, the short arm end parts of the first L-shaped clamping pin and the second L-shaped clamping pin are oppositely arranged, and the distance between the two short arm end parts is the outer diameter of the water gap.

Preferably, the distance between the zero scale mark and the end part of the ruler arm connected with the first L-shaped clamping foot is equal to the length of the short arm of the first L-shaped clamping foot.

Preferably, one end surface of the sliding block and the end part of the short arm of the second L-shaped clamping pin are on the same straight line.

Compared with the prior art, the utility model has the advantages of:

the utility model discloses block the mouth of a river simultaneously with two card feet during the measurement and can directly read out numerical value, operation process is simple and convenient, and numerical value reads convenient accuracy.

Detailed Description

The present invention will be described in further detail with reference to the following embodiments.

As shown in fig. 1, the utility model relates to a novel direct reading formula mouth of a river external diameter measuring tool, including the chi arm 1 of taking the scale, first L type calorie of foot 2 and second L type calorie of foot 3, the one end at chi arm 1 is passed through the bolt fastening to the long arm end of first L type calorie of foot 2, is provided with zero scale mark on being close to chi arm 1 of first L type calorie of foot 2, zero scale mark equals the forearm length of first L type calorie of foot 2 with the distance that is connected with chi arm 1 tip of first L type calorie of foot 2, and zero scale mark aligns with the tip of first L type calorie of foot 2 forearm at vertical unwrapping wire promptly.

The ruler arm 1 is sleeved with a slidable sliding block 4, the long arm end part of the second L-shaped clamping pin 3 is vertically connected to the sliding block 4 through a screw, the short arm end parts of the first L-shaped clamping pin 2 and the second L-shaped clamping pin 3 are oppositely arranged, the distance between the two short arm end parts is the outer diameter of a water gap, and one end face of the sliding block 4 and the short arm end part of the second L-shaped clamping pin 3 are on the same straight line.

When the measuring tool is used for measuring, the two clamping pins are used for clamping the water gap simultaneously, the distance between the zero scale mark and one end face of the sliding block 4 is the numerical value of the outer diameter of the water gap, and the two clamping pins can be conveniently replaced when the positions, contacting the water gap, of the two clamping pins are abraded too much, so that the precision of the measuring tool is improved.

In addition to the above embodiments, the present invention also includes other embodiments, and all technical solutions formed by equivalent transformation or equivalent replacement should fall within the protection scope of the claims of the present invention.
