Abstract
The invention relates to a special measuring tool, in particular to an axial special measuring tool for an explosive charge, which comprises base and an explosive charge positioning seat arranged on the base, and is characterized in that: three groups of axial measurement mandrills are arranged above the base respectively; the measurement mandrills are connected with a lever dial test indicator through connecting rods respectively; and a pushing cylinder is arranged above the explosive charge positioning seat. The axial special measuring tool has the characteristics of high measurement accuracy, high batch test efficiency, low manufacturing cost, simple structure, convenient use and the like.
Description
Technical field
The present invention relates to a kind of special measuring tool, especially relate to a kind of axial special measuring tool for explosive charge.
Background technology
As everyone knows, at present a lot of producers are to utilize kind of calliper when producing perforating bullet shell case product mostly, or take multiple measurements through the cartoon rule of single-ended no-go gage or drift.When actual production, forms repeatedly because of measurer is different and measure, thereby can't guarantee the measuring accuracy of product size, the relative product detection stand-by period is also very long, and the efficient of measure batch is lower, and the manufacturing cost of a plurality of measurers is higher relatively.
Summary of the invention
The present invention mainly is to the technical matters that the existing in prior technology measuring accuracy is low, batch detection efficient is low, manufacturing cost is high, and the axial special measuring tool for explosive charge of a kind of measuring accuracy height, batch detection efficient height, low cost of manufacture is provided.
Above-mentioned technical matters of the present invention mainly is able to solve through following technical proposals: a kind of axial special measuring tool for explosive charge; Comprise base and be arranged on the perforating bullet positioning seat on the base; It is characterized in that described base top is respectively arranged with three groups of radial measurement push rods; Described measurement push rod links to each other with lever indicator through connecting rod respectively, and described perforating bullet positioning seat top is provided with the promotion cylinder.Measure the radial dimension of three positions of perforating bullet respectively through three groups of radial measurement push rods; Measure the height of three end faces through one-time positioning; The size of reading three sagittal planes just can the lever indicator on being arranged on base; Thereby know the qualification rate of perforating bullet radial dimension, easy and simple to handle, simple in structure.
As preferably, described three groups of radial measurement push rods have comprised that push rod is measured at the top, push rod is measured at the middle part and push rod is measured in the bottom; Described middle part is measured top stem casing and is located between top measurement push rod and the bottom measurement push rod.Through position different three groups push rod radially, radial dimension that can three diverse locations of one-shot measurement, simple and practical.
As preferably, be arranged with the spring that rises outside the described bottom measurement push rod, the described spring that rises is embedded in the perforating bullet positioning seat.When cylinder promotes perforating bullet and moves to the end downwards, measure cooperating between rise spring and the perforating bullet in the push rod outside through being set in the bottom, can from lever indicator, read the size of perforating bullet bottom sagittal plane accurately, rational in infrastructure, design is ingenious.
As preferably, described base side is provided with support set, and described support set top is provided with upper end cover, and described promotion cylinder is fixed on the upper end cover.Install firmly, manufacturing cost is cheap relatively.
As preferably, be provided with back up pad above the described base.Firm supporting, simple installation, working strength height.
As preferably; The radial width of described top measurement push rod equals the radial width at perforating bullet top; The radial width of described middle part measurement push rod equals the radial width at perforating bullet middle part, and the radial width of described bottom measurement push rod equals the radial width of perforating bullet bottom.Measuring accuracy is high, easy and simple to handle.
Therefore, the present invention has measuring accuracy height, batch detection efficient height, low cost of manufacture, characteristics such as simple in structure, easy to use.
Description of drawings
Accompanying drawing 1 is a kind of structural representation of the present invention.
Embodiment
Pass through embodiment below, and combine accompanying drawing, do further bright specifically technical scheme of the present invention.
Embodiment 1:
Shown in Figure of description 1; A kind of axial special measuring tool for explosive charge; Comprised base 1 and be arranged on the perforating bullet positioning seat 2 on the base, the base top is respectively arranged with three groups of radial measurement push rods, and three groups of radial measurement push rods have comprised that push rod 6 is measured at the top, push rod 7 is measured at the middle part and push rod 8 is measured in the bottom; Measure push rod for three groups and link to each other with lever indicator 4 through connecting rod 3 respectively, perforating bullet positioning seat top is provided with and promotes cylinder 5.The middle part is measured top stem casing and is located between top measurement push rod and the bottom measurement push rod.The bottom is measured the push rod outside and is arranged with the spring 9 that rises, and the spring that rises is embedded in the perforating bullet positioning seat.The base side is provided with support set 10, and the support set top is provided with upper end cover 11, promotes cylinder and is fixed on the upper end cover.The base top is provided with back up pad 12.The radial width of top measurement push rod equals the radial width at perforating bullet top, and the radial width of middle part measurement push rod equals the radial width at perforating bullet middle part, and the radial width of bottom measurement push rod equals the radial width of perforating bullet bottom.
When using axial special measuring tool for explosive charge to measure perforating bullet 13 radial dimensions; Press down through promoting cylinder earlier; Perforating bullet to pressing to the bottom, is close to perforating bullet positioning seat upper surface, measures the radial dimension of three positions of perforating bullet through three groups of radial measurement push rods respectively; Measure the height of three end faces through one-time positioning; Just can read the size of three sagittal planes the lever indicator on being arranged on base, thereby know the qualification rate of perforating bullet radial dimension, easy and simple to handle, simple in structure.
Should be understood that this embodiment only to be used to the present invention is described and be not used in the restriction scope of the present invention.Should be understood that in addition those skilled in the art can do various changes or modification to the present invention after the content of having read the present invention's instruction, these equivalent form of values fall within the application's appended claims institute restricted portion equally.
