Description
Technical Field
The utility model relates to a vernier type steel cold and hot gauge.
Background
Generally, a hot rolling steel mill uses a hot inspection template to carry out rough inspection on the size of a finished product in a hot state on a cold bed of a section steel production line, uses a cold inspection template to carry out rough inspection on the size of the finished product in the cold state on a stacking chain, and uses a vernier to carry out accurate spot inspection. The cold and hot inspection templates are adopted to measure the finished product size accurately, and only the fastest time is used to measure whether the finished product size of the profile steel is within the tolerance range. Because of various types of steel products, a large number of cold and hot inspection templates need to be prepared, the cold and hot inspection templates need to be inspected periodically, worn or deformed are scrapped and manufactured again, and in addition, the large number of cold and hot inspection templates are difficult to store and manage, and the cost is high.
Disclosure of Invention
The utility model aims to provide a vernier type steel cold and hot detection measuring tool which can replace cold and hot detection templates, is adjustable and can be used for various product specifications.
The technical scheme includes that the vernier type steel cold and hot gauge comprises an L-shaped main scale, length scales are arranged on the main scale, a movable measuring claw is sleeved on the main scale in a sliding fit mode, a handle is hinged to the right side end of the main scale, a negative tolerance measuring block is embedded in the left side wall of the movable measuring claw in a sliding mode, an adjusting screw is arranged on the back face of the negative tolerance measuring block, the adjusting screw extends out of the back face of the movable measuring claw, a horizontally arranged guide chute is arranged at the upper portion of the movable measuring claw, a stop elastic piece is arranged in the top face of the guide chute through an adjusting knob, and the stop elastic piece is in contact with the top face of the main scale.
At present, the production line mainly uses I-steel and H-steel, one class is provided with 2 tolerance measuring scales, 1I-steel is adjusted, and 1I-steel is inspected; and setting the tolerance ruler for cold and hot inspection according to the numerical values in the specification standard table before measurement, so that the tolerance range measurement of all product specifications can be realized, and the on-site cold and hot inspection sample plate shelves are abandoned and are not used any more. The measuring tool can be applied to various hot rolled steel production lines such as angle steel, channel steel, I-steel, H-steel, cathode flat steel, T-steel and the like, can replace a cold and hot inspection template, is adjustable, can be used in various product specifications, and has good popularization and application prospects.

Description of the embodiments
The utility model provides a cold and hot measuring tool of vernier type steel, shown in fig. 1, 2, includes an L shape main scale 3, has length scale on the main scale 3, and the slip fit suit is provided with the removal measuring jaw 6 on the main scale 3, and a handle 1 is articulated through special-shaped nut 2 to the right side end of main scale 3, the left side wall of removal measuring jaw 6 slip-fit be equipped with a negative tolerance measuring block 5, this negative tolerance measuring block 5 back is provided with an adjusting screw 7, adjusting screw 7 stretches out from the removal measuring jaw back. The upper part of the movable measuring claw 6 is provided with a horizontally arranged guide chute 4, a stop spring piece 9 is arranged in the top surface of the guide chute 4 through an adjusting knob 8, and the stop spring piece 9 is contacted with the top surface of the main scale 3. The measuring ruler body is made of high temperature resistant tool steel (T8 MnA), and scales are marked on the ruler body. The movable measuring claw is arranged on the main scale through a slideway, the positive tolerance size is determined, and the movable measuring claw is locked and then fixed on the main scale. The movable measuring claw body is also marked with scales, and the measuring precision is 0.02mm. The movable measuring claw is provided with a negative tolerance measuring marking block, and the measuring block is locked after the negative tolerance size is adjusted through the knob. The negative tolerance measurement marking block and the movable measurement claw are provided with scales, and the measurement precision is 0.1mm. The tail of the main ruler is connected with the handle by adopting a special nut, and the main ruler and the handle can adjust the turning angle, so that the use of different measuring positions is convenient. The handle is made of light aluminum alloy and can be replaced in order to lighten the weight.
