Abstract
The utility model discloses an inner diameter measuring scale. The inner diameter measuring scale includes a depth indicator, a depth indicator sleeve, an indicator support, a press board, an indicator rod, an extension rod and an extension rod head. The indicator rod is in the shape of a hollow cylinder. The upper end of the indicator rod is connected with the indicator support fixedly. The lower end of the indicator rod is connected with one end of the extension rod. The extension rod is in the shape of a hollow cylinder. The other end of the extension rod is connected with the extension rod head fixedly. The extension rod head is in the shape of a round table. An end of the depth indicator sleeve is disposed in the indicator rod and is fixed on the indicator support through the press board. The depth indicator is disposed in the depth indicator sleeve and can slide along the inner wall of the sleeve. The inner diameter measuring scale provided by the utility model is simple in structure, low in manufacturing cost, convenient to use, lowered in working difficulty and improved in working efficiency. Besides, extension rods of different standard lengths can be changed for inner diameters in different size ranges, so that the measuring range is large.
Description
Technical field
The utility model relates to a kind of dip stick, especially a kind of internal diameter of the pipeline dip stick.
Background technology
The measuring channel internal diameter is used micrometer inside caliper more, and micrometer inside caliper is to utilize the screw pair principle to distance separating between the spherical measurement face in main body two ends, carries out the general inside dimension survey instrument of reading.
Micrometer inside caliper must be connected with its micrometer head with the extension bar of size maximum when measuring and use, and once order is received the measurement contact, to reduce the axis bending after connecting; Should see during the side amount that micrometer head is fixed and the variable quantity when unclamping.In daily production, during with internal diameter chi measured hole, it is measured contact measurement face is supported on the measured surface, adjust microdrum, the measurement face of microdrum one side is swung in the radial section in hole, find out minimum dimension, tighten gib screw then and take out and reading, it is direct reading also not tighten screw.
More complicated when measuring internal diameter size with micrometer inside caliper, inefficiency can't satisfy the measurement of needs, the especially large-diameter pipeline of batch process.
The utility model content
The technical problems to be solved in the utility model provides a kind of inner diameter measurement chi, the utility model inner diameter measurement chi is simple in structure, cost of manufacture is low, easy to use, reduce work difficulty, improved work efficiency, and can change the extension bar of various criterion length, can measure the internal diameter size of different range, measurement range is wide.
For solving the problems of the technologies described above, technical solution adopted in the utility model is:
A kind of inner diameter measurement chi comprises pit gauge, pit gauge sleeve, rod support, pressing plate, chi bar, extension bar and extension bar head; The chi bar is hollow cylindrical, fixedlys connected with rod support in the upper end of chi bar, and the lower end of chi bar is connected with extension bar, and extension bar is hollow cylindrical, and the other end of extension bar is fixedlyed connected with the extension bar head, and the extension bar head is truncated cone-shaped;
Pit gauge sleeve one end is positioned at the chi bar, and is fixed on the rod support by pressing plate; Pit gauge and pit gauge sleeve are provided with scale mark.
Pit gauge is positioned at the pit gauge sleeve and can slides along described sleeve lining.
Rod support is provided with trip bolt, after measurement finishes it is tightened, and can avoid the random play of the preceding pit gauge of reading.
The extension bar head is that wimet is made, wimet, and the hardness height, wear-resistant, during measurement wimet extension bar head contacted the wearing and tearing when avoiding using with testee, measure accurately.
The lower end of chi bar and extension bar by changing the extension bar of various criterion length, just can be measured the internal diameter size of different range by being threaded.
The beneficial effect that adopts technique scheme to produce is: the utility model inner diameter measurement chi is simple in structure, cost of manufacture is low, easy to use, reduced work difficulty, improved work efficiency, and can change the extension bar of various criterion length, and can measure the internal diameter size of different range, measurement range is wide; Pit gauge can pull out fast, regain and be applicable to that measuring accuracy requires the inner diameter measurement greater than 0.5mm.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
Fig. 1 is structural representation of the present utility model;
1 is pit gauge, and 2 is the pit gauge sleeve, and 3 is rod support, and 4 is pressing plate, and 5 is the chi bar, and 6 is extension bar, and 7 is the extension bar head, and 8 is trip bolt.
Embodiment
A kind of inner diameter measurement chi comprises pit gauge 1, pit gauge sleeve 2, rod support 3, pressing plate 4, chi bar 5, extension bar 6 and extension bar head 7; Chi bar 5 is hollow cylindrical, fixedlys connected with rod support 3 in the upper end of chi bar 5, and the lower end of chi bar 5 and extension bar 6 are by being threaded, and extension bar 6 is hollow cylindrical, and the other end of extension bar 6 is fixedlyed connected with extension bar head 7, and extension bar head 7 is truncated cone-shaped;
A kind of inner diameter measurement chi comprises pit gauge 1, pit gauge sleeve 2, rod support 3, pressing plate 4, chi bar 5, extension bar 6 and extension bar head 7; Chi bar 5 is hollow cylindrical, fixedlys connected with rod support 3 in the upper end of chi bar 5, and the lower end of chi bar 5 and extension bar 6 are by being threaded, and extension bar 6 is hollow cylindrical, and the other end of extension bar 6 is fixedlyed connected with extension bar head 7, and extension bar head 7 is truncated cone-shaped;
When measuring with the utility model inner diameter measurement chi, extension bar head 8 is supported on the measured surface, outwards extracts pit gauge out, the measurement face that makes pit gauge one side in the hole cross-sectional periphery perpendicular to bus swing, find out full-size, tighten gib screw then and take out and reading.Measurement result equals the pit gauge reading and adds that the chi pole length adds extension bar length.
