Abstract
The utility model discloses an improved measuring tool of a special caliper, which comprises a caliper body, wherein the lower ends of two caliper arms of the caliper are respectively and horizontally provided with a roller; and an arc-shaped dividing rule is fixedly connected to one caliper arm, an arc-shaped sliding chute is arranged on the arc-shaped dividing rule, and a fixing and regulating nut is arranged on the other caliper arm and extends out of the arc-shaped sliding chute. According to the improved measuring tool of the special caliper, the abrasion of the lower ends of the caliper arms can be effectively lowered, the on-line measuring accuracy is enhanced, the structure is simple, and the use is convenient.
Description
Technical field
The utility model relates to a kind of caliper measurements instrument, particularly a kind of improved special caliper survey tool that is used for steel plant's rolling production.
Background technology
Present domestic bar and high line production line adopt continuous rolling process mostly.Actual red the size that the operative employee must be regular when producing with rolled piece in clamp and the Steel Ruler on-line measurement slightly, and in time the groove roll gap is adjusted according to measurement result, red suitable size value obtained.Because rolled piece is in high-speed motion state forward in the operation of rolling, during measurement clamp with red between have sliding friction, the clamp shake is very big, is difficult to the assurance certainty of measurement, influences the stability of technology.If when there is pit on red surface, very easily clamp are tangled, take in the guide and guard and go, there is very big potential safety hazard.
Summary of the invention
The purpose of this utility model is to provide a kind of improved special caliper survey tool, can reduce the wearing and tearing of tong arm lower end effectively, improves the on-line measurement precision, and is simple in structure, easy to use.
The purpose of this utility model is to realize like this, a kind of improved special caliper survey tool, comprise the clamp body, two tong arm lower ends of clamp level respectively are installed with a roller, affixed a curved rule on tong arm wherein, one arc chute is being set on the curved scale chi, a secured adjusted nut is being set on the another tong arm, the secured adjusted nut stretches out from arc chute.
The newly-designed clamp of the utility model are equipped with roller respectively in tip, tong arm lower end, make between clamp and red to become rolling friction, reduce coefficient of friction, and the shake when reducing to measure improves certainty of measurement.The graduated curved scale chi of mounting strap can directly be read measurement data on clamp, avoided again with Steel Ruler measure two pincers points of clamp apart from the time measure error that produces; Brought into accidentally by rolled piece if meet clamp, because the length of curved scale chi is slightly larger than the guide and guard that respectively enter the mouth, clamp can come off voluntarily, have eliminated potential safety hazard.The utility model can reduce the wearing and tearing of tong arm lower end effectively, improves the on-line measurement precision, and is simple in structure, easy to use.
Description of drawings
Below in conjunction with accompanying drawing the utility model is described in further detail.
Fig. 1 is a perspective view of the present utility model.
The specific embodiment
A kind of improved special caliper survey tool, as shown in Figure 1, comprise clamp body 1, two tong arm lower ends of clamp level respectively are installed with a roller 4, affixed a curved rule 2 on tong arm wherein, one arc chute is being set on the curved scale chi 2, a secured adjusted nut 3 is being set on the another tong arm, secured adjusted nut 3 stretches out from arc chute.The cross section of roller 4 outer peripheral edges is triangular in shape.The utility model can reduce the wearing and tearing of tong arm lower end effectively, improves the on-line measurement precision, and is simple in structure, easy to use.
The utility model be applicable to high line and bar production unit thick in rolled piece measure, at bar and high line unit thick, in roll and promote the use of.
Claims (2)
