Abstract
The utility model discloses an expanding-spring inside meter with anti-rotating function. Because the wedge principle is adopted by a measuring head and a push rod, the cone angle error of the push rod is changed into the indicating value stability of the expanding-spring inside meter when the measuring head responds to measured change, which makes the push rod generate movement and rotation. So the angle of the cone angle and the surface roughness of the push rod are directly reflected to an index gauge. Thereby, the machining precision requirement of the cone angle of the push rod is higher. The expanding-spring inside meter with anti-rotating function comprises a meter face 1 and a meter needle 9. The meter face 1 is arranged on a meter frame 2. A spring push rod 3 is arranged in the meter frame 2. The lower end of the spring push rod 3 is provided with a push rod 4. The push rod 4 is provided with a hole, and is connected with a cover 5 which is provided with a groove 8 by a pin shaft 6. The outer end surface of the push rod 4 is provided with the measuring head 7. The utility model is used on an expanding-spring inside meter.
Description
Technical field: the utility model relates to a kind of expansion string type inside meter with anti-rotating function.
Background technology: the expansion string type inside meter is measured the inside dimension and the shape error thereof of part, be the compression by expansion string type inside meter dial framework gauge head and open and drive push rod and move up and down, make the indicator gage finger revolution, because wedge principle is adopted in gauge head and push rod design, when the measured variation of gauge head response makes push rod produce displacement, and the displacement of push rod is accompanied by the rotation of push rod, then the error of push rod cone angle changes expansion string type inside meter stability of display into, so it is the angle and the surfaceness of push rod cone angle are directly reflected into indicating gauge, therefore higher to the requirement on machining accuracy of push rod cone angle.
Summary of the invention: the purpose of this utility model provides a kind of measuring accuracy height, and stability of display is good, easily the expansion string type inside meter with anti-rotating function of processing.
Above-mentioned purpose realizes by following technical scheme:
Expansion string type inside meter with anti-rotating function, its composition comprises: dial plate and indicator, it is characterized in that: described dial plate is contained on the dial framework, in the described dial framework spring spindle is housed, there is push rod the lower end of described spring spindle, porose and be connected with overcoat on the described push rod with groove with bearing pin, on the outer face of described push rod gauge head is arranged.
The above-mentioned expansion string type inside meter with anti-rotating function, described overcoat is a copper sheathing, and puts outside described and be processed with groove.
The above-mentioned expansion string type inside meter with anti-rotating function, described bearing pin is a straight pin.
This technical scheme has following beneficial effect:
1. the expansion string type inside meter with anti-rotating function of the present utility model, employing is groove milling on copper sheathing, boring edge straight pin on the push rod, straight pin on the push rod is fallen in the groove of copper sheathing, the assurance push rod only moves up and down and does not rotate, so just, limited the rotation of push rod in the process of moving up and down, reduced of the influence of push rod cone angle error, the stability of display of having improved product expansion string type inside meter stability of display.
2. characteristics such as the structure that this product adopted can reduce difficulty of processing, and has the measuring accuracy height, and error is little.
Description of drawings: accompanying drawing 1 is the structural representation of this product.
Accompanying drawing 2 is partial enlarged drawings of accompanying drawing 1.
Below in conjunction with the description of drawings embodiment:
Embodiment 1:
Expansion string type inside meter with anti-rotating function, its composition comprises: dial plate 1 and indicator 9, described dial plate 1 is contained on the dial framework 2, in the described dial framework 2 spring spindle 3 is housed, there is push rod 4 lower end of described spring spindle 3, porose and be connected with overcoat 5 on the described push rod 4 with groove 8 with bearing pin 6, gauge head 7 is arranged on the outer face of described push rod 4.
Embodiment 2:
The above-mentioned expansion string type inside meter with anti-rotating function, described overcoat 5 is a copper sheathing, and puts groove milling 8 outside described.
Embodiment 3:
The above-mentioned expansion string type inside meter with anti-rotating function, described bearing pin 6 is a straight pin.
