Abstract
The utility model provides an original gauge length dotting device for samples with metallic mechanical properties, including two thread rods with cones and a metallic plate; two thread rods are installed on the metallic plate by nuts according to the required original gauge length; and the metallic plate is processed with a row of through holes or processing bar-shaped grooves for installing the thread rods and adjusting the distance. When in use, a round sample is put on a V-shaped iron, and the sample is dotted with a mark of the original gauge length by a dotter with its two tips; if the sample is a rectangle, then directing to dot on a workbench; and a set of devices only marks an original gauge length. Compared with the prior art, the utility model has advantages of clear and accurate marking and doubled operating efficiency.
Description
Technical field
The utility model is the original gauge length device for dotting of Metal Mechanic Property sample, belongs to the technical field of structures of product.
Background technology
When measuring Metal Mechanic Property, need carry out gauge length to original sample, write " use tick marks, carefully line or the thin original gauge length of line of ink marker mark " among the 8th of the GB/T228-2002 exactly, do not indicate and adopt concrete which kind of device that adopts.This standard is write " using tick marks, thin line " and is referred to adopt the mechanical type labelling apparatus.Each factory adopts vernier caliper directly to portray method or line of ink marker labelling method more.Adopt vernier caliper directly to portray the shortcoming of method: when test button hardness was big, mark was too shallow, does not often see mark after sample is broken, and causes the consequence that can't measure, and vernier caliper is worn, influence measuring accuracy and mark precision from now on; Adopt the shortcoming of line of ink marker labelling method: the one, be difficult for finding the device that can mark the thin line of ink marker; The 2nd, operation easier is big, is difficult for marking the line of ink marker in accurate position; The 3rd, inefficiency.
Summary of the invention
The present invention designs at the shortcoming that exists in the above-mentioned prior art just provides a kind of Metal Mechanic Property sample original gauge length device for dotting, its objective is the device that the original gauge length of a kind of energy accurate mark Metal Mechanic Property sample is provided.
Technical solution of the present invention is that the method for scoring that adopts just usually changes the method for getting ready into, its concrete technical measures are: this device is made up of threaded rod, a sheet metal of two band cones, with nut two threaded rods are installed on the sheet metal according to needed original gauge length, are processed with through hole or processing bar-shaped trough that a row is used to install threaded rod and roll adjustment on the sheet metal.During use, circular specimen is placed on the V shape iron, on sample, gets the mark of original gauge length with two tips of tapper; If rectangular specimen then directly is placed on the worktable and gets ready.A kind of original gauge length of one a covering device mark.

Embodiment
Below with reference to drawings and Examples the utility model device is further described:
Shown in accompanying drawing 1～4, the original gauge length device for dotting of this kind Metal Mechanic Property sample, it is characterized in that: this device is made up of the threaded rod 1 of two band cones, a sheet metal 2, threaded rod 1 adopts the higher ferrous material of hardness, as 20CrMn, process two rod members, an end is cone, and the hardened face hardness at cone tip should be not less than HRC62; The equal machining screw of the other end is installed in two threaded rods 1 on the round-meshed sheet metal 2 of processing according to needed original gauge length with two self-locking nuts 3, and sheet metal can adopt thicker aluminium sheet.The roll adjustment and the location of threaded rod 1 are processed with row's manhole 4 or processing bar-shaped trough 5 on sheet metal 2 for convenience.Generally speaking, the original gauge length of Metal Mechanic Property sample has kinds more than ten such as 25,30,40,50,60,80,100,110,120,130,140, and unit is mm.
During use, circular specimen 6 is placed on the V shape iron 7, on sample, gets the mark of original gauge length with two tips of tapper; If rectangular specimen then directly is placed on the worktable and gets ready.A kind of original gauge length of one a covering device mark.Also can be after accomplishing fluently a stomidium on the sheet metal, the other end is adjusted by the size of needed original gauge length, adjusts to the distance of requirement at any time.
The utility model device is that mark is clear, accurate with its advantage compared with prior art, and operating efficiency has realized significantly improving.
