Abstract
The utility model relates to an external diameter measuring meter for measuring an external diameter of a front edge. The external diameter measuring meter comprises a measuring support, wherein two ends of the measuring support are respectively provided with left and right projection blocks projecting to one same side, the external diameter measuring meter further comprises a through hole arranged on the right projection block, a threaded hole arranged on the left projection block, a dial indicator arranged on the through hole through a measuring rod, a column-shaped measuring head connected with a bottom portion of the measuring rod of the dial indicator, and a positioning measuring head of which a bottom portion is arranged in the threaded hole. The external diameter measuring meter has a simple structure; before measurement, the dial indicator is adjusted to a proper position and is fastened by screws at side faces, the external diameter measuring meter is placed on a standard dimension of a workpiece to be measured, zero setting of the dial indicator is carried out, the checked external diameter measuring meter is placed on the workpiece, a measuring base surface is arranged on an upper plane, the positioning measuring head contacts an external diameter, the external diameter measuring meter is turned by taking the positioning measuring head as a fulcrum, the external diameter measuring meter is made to turn and pass by a diameter position of which the external diameter is a largest one, a pointer points to a largest scale value which is deviation of the workpiece deviating from the standard dimension.
Description
Technical field
The utility model relates to a kind of external diameter scale of measuring the seam external diameter.
Background technology
When machining bearing seat diameter was the seam of 26mm, because seam has only 2 mm height, and size was big, needs the outside micrometer of 250-275 mm specification, weight is bigger, is difficult for during measurement taking putting down, inconvenient workman's operation, influence measuring accuracy, and measure slowly, influence production efficiency.And the scale mark of outside micrometer is not obvious, and it is bigger influenced by light, is difficult for reading, increases operator's measurement difficulty, increases personal error.
The utility model content
Technical problem to be solved in the utility model provides a kind of simple in structure, external diameter scale of measuring the measurement seam external diameter convenient, that measuring accuracy is high.
In order to address the above problem, the utility model provides a kind of external diameter scale of measuring the seam external diameter, comprise: measure support, the two ends of measurement support are respectively equipped with left projection and the right projection to the same side projection, be located at through hole on the right projection along the length direction of measuring support, and be located at threaded hole on the left projection along the length direction of measuring support, be located at dial gauge on the through hole by sounding rod, with the cylindricality gauge head that the bottom of the sounding rod of dial gauge links to each other, the location gauge head in the described threaded hole is located in the bottom; The bottom of described location gauge head is provided with the screw thread that cooperates for described threaded hole.
Be provided with on the described measurement support and between described left and right projection be used to the slot to make way that holds cylindricality gauge head and location gauge head.
One side of described right projection is provided with threaded hole.Screw in this threaded hole is used for the data of fixing described dial gauge.
The utility model has positive effect with respect to prior art: the external diameter scale construction of measurement seam external diameter of the present utility model is simple.Before the measuring workpieces, adjust dial gauge to correct position, and with the screw lock of side, the external diameter scale is placed on the standard size that needs measuring workpieces, the pointer of adjustment dial gauge is in zero-bit; The external diameter scale that check and correction is good is placed on the workpiece, and the measurement basal plane is placed on the plane, location gauge head contact external diameter, and according to the size difference, beat of pointer position difference, the indicated scale of pointer is workpiece and departs from standard-sized deviation.
Description of drawings
For the utility model can more clearly be understood, below in conjunction with the drawings and specific embodiments the utility model is described in further detail:
Fig. 1 is the structural drawing of the external diameter scale of measurement seam external diameter of the present utility model;
Fig. 2 is the upward view of Fig. 1.
Embodiment
See Fig. 1 to 2, the external diameter scale of the measurement seam external diameter of present embodiment, comprise: measure support 1, the two ends of measurement support 1 are respectively equipped with left projection 1-1 and the right projection 1-2 to the same side projection, be located at through hole on the right projection 1-2 along the length direction of measuring support 1, and be located at threaded hole on the left projection 1-1 along the length direction of measuring support 1, be located at dial gauge 2 on the through hole by sounding rod, with the cylindricality gauge head 3 that the bottom of the sounding rod of dial gauge 2 links to each other, the location gauge head 4 in the described threaded hole is located in the bottom; The bottom of described location gauge head 4 is provided with the screw thread that cooperates for described threaded hole.
Be provided with on the described measurement support 1 and between described left and right projection be used to the slot to make way 5 that holds cylindricality gauge head 3 and location gauge head 4.
The side of described right projection 1-2 is provided with threaded hole.Screw in this threaded hole is used for the data of fixing described dial gauge 2.
Before the measuring workpieces, adjust dial gauge to correct position, and with the screw lock of side; The external diameter scale is placed on the standard size that needs measuring workpieces, adjusts the pointer of dial gauge in zero-bit; The external diameter scale that check and correction is good is placed on the workpiece, the measurement basal plane is placed on the plane, and gauge head contact external diameter in location is that fulcrum rotates the external diameter scale with the location gauge head, it is slipped over from the external diameter maximum gauge, and the indicated maximum scale of pointer is workpiece and departs from standard-sized deviation.
It is long that the external diameter scale of measurement seam external diameter of the present utility model is measured the basal plane span, can satisfy the measurement requirement of large scale external diameter; Dial gauge 2 scales are obvious, and reading fast, intuitively is not subjected to light and artificial factor; Dial gauge 2 precision 0.01 mm, the measuring accuracy height; Increase or the minimizing extension bar, can satisfy the measurement requirement of different product size, highly versatile; Simple, convenient, fast, the operator is required low, to make simply, cost is low.
