Abstract
The utility model relates to an immersion water-gap wall-thickness measuring caliper, which belongs to the technical field of the measuring tool, and is used for resolving the problem that the prior caliper is difficult to precisely measure the wall thickness of the immersion water gap, and is provided with two symmetric jaws, wherein, one end of the two jaws are movably hinged with each other, and the other end is a measuring end and characterized in that two jaws symmetrically extend with a hinge shaft as the center corresponding to the measuring end, so as to form a dual-jaw caliper with the left side and the right side being symmetric to each other; with the consistence property of the openness and retraction of the two jaws, the measuring result of the measuring end that is deeply penetrated into a pipe body is directly reflected on the other end outside the pipe body, thereby resolving the problem that the prior caliper is difficult to measure the wall thickness all around the immersion water gap; moreover, the caliper has simple structure and convenient, rapid and correct measurement operation, and is applied to the irregular tubular components such as the immersion water gap.
Description
Technical field
The utility model relates to the measurer clamp, in particular for measuring the clamp of smelting tundish exit submersed nozzle wall thickness, belongs to the measurer technical field.
Background technology
Submersed nozzle be molten steel by the mozzle of tundish to crystallizer, be the tubular body shown in Fig. 1,2.Whether mouth of a river wall thickness meets technological requirement plays crucial effects in the slab casting process, the spoilage when thin excessively under molten steel impacts is higher, the reduction in serviceable life; When blocked up in the mouth of a river through dwindling, influence steel-passing amount, influence sheet billet continuous casting output; Wall unevenness then can cause the fluctuation of crystallizer liquid steel level, influences the covering slag molten state, causes phenomenons such as volume slag bleed-out, slag bonding easily.The wall thickness of guaranteeing submersed nozzle meets technological requirement, will carry out omnibearing accurate measurement to mouth of a river wall thickness.Adopt the current clamp that pass through obviously can only measure the wall thickness that the import and export place is immersed at the mouth of a river, be difficult to reach the mouth of a river than the position, deep, the measuring point is restricted, measurement accuracy is low, for this reason, need to improve to existing measurer clamp, make its can comprehensive accurate measurement submersed nozzle wall thickness everywhere.
Summary of the invention
The purpose of this utility model provides a kind of submersed nozzle wall thickness measuring clamp, and these clamp should be able to make things convenient for and measure submersed nozzle wall thickness everywhere accurately.
The alleged problem of the utility model realizes with following technical scheme:
A kind of submersed nozzle wall thickness measuring clamp, symmetrically arranged claw is arranged, and an end of two claws is movably hinged, the other end is the measurement termination, and its improvement is, described two claws are respectively that relative measurement termination, center symmetry is extended with the jointed shaft, form two claw clamp of left and right symmetry.
Above-mentioned submersed nozzle wall thickness measuring clamp, two claws of described symmetry are the arc claw to outer lug, and local little arc convex is wherein arranged respectively on the left and right symmetrical arc raised section of a claw.
Above-mentioned submersed nozzle wall thickness measuring clamp, two claws of described symmetry are the stretched claw.
The utility model makes the claw of existing clamp extend to form two claws with the pin joint for the center symmetry, utilize the measurement result that two left and right ends of claw open, the characteristic of retraction degree unanimity will be deep into measuring junction in the body to reflect by the outer other end correspondence of body, thereby well solved the problem that existing clamp are difficult to comprehensive accurate measurement submersed nozzle wall thickness, and have simple in structure, measuring operation easily and fast, remarkable superiority accurately, suitable wall thickness measuring utensil as irregular tubular members such as submersed nozzles uses.
Description of drawings
Fig. 1 is the structure of embodiment 1 and measures view;
Fig. 2 is the structure of embodiment 2 and measures view.
Consult Fig. 1.Existing clamp all are that an end of two claws is movably hinged by jointed shaft, the other end is the measuring junction that contacts with tested position, measuring junction needs to detach by the side keeping measuring under the contact condition, measures the physical size numerical value at the tested position that contact condition reacts then by measurers such as slide calliper rule.Improvement of the present utility model is, the hinged termination that makes two claws is respectively that center, relative measurement termination symmetry are extended with the jointed shaft, form two claw clamp of left and right symmetry, when two claw terminations of left end as with measurement termination that measured position contacts the time, two claw terminations of right-hand member directly reflect the actual measurement contact position of left end two claws, and the distance that measure right-hand member two claw terminations between by measurers such as slide calliper rule this moment just obtains measurement result accurately.
Still consult Fig. 1.Embodiment 1 shown in the figure is used to measure the lower part outlet place wall thickness of submersed nozzle.Two claw middle parts are movably hinged by jointed shaft, the left and right corpus unguis of two symmetries is the arc pawl to outer lug, wherein on the left and right arc convex section of a claw also the hydraucone at the lower part outlet place of submersed nozzle be provided with local little arc convex, radian and arc length to the radian section of outer lug on the left and right pawl of two claws, wherein the radian and the arc length of the little arc convex in left and right part on the claw are decided on the geomery of concrete submersed nozzle.
Consult Fig. 2.Embodiment 2 shown in the figure is used to measure the wall thickness of submersed nozzle top straight section part.The left and right end of two claws is the stretched claw of symmetry, and length is decided on the straight section portion size of concrete submersed nozzle.
Claims (3)
1. submersed nozzle wall thickness measuring clamp, symmetrically arranged claw is arranged, and an end of two claws is movably hinged, the other end is to measure the termination, it is characterized in that, described two claws are respectively that relative measurement termination, center symmetry is extended with the jointed shaft, form two claw clamp of left and right symmetry.
2. submersed nozzle wall thickness measuring clamp according to claim 1 is characterized in that, two claws of described symmetry are the arc claw to outer lug, and local little arc convex is wherein arranged respectively on the left and right symmetrical arc raised section of a claw.
