Description

The seal ring detector

(1) technical field

The utility model relates to a kind of seal ring detector.

(2) background technique

Seal ring particularly O RunddichtringO is widely used in pneumatic, Hydraulic Field.Common kind is a lot, and only the regulation of GB3452.1-82 just has kind more than 100, also has many non-standard seal rings, in frequent use replacing process, confirms that the size of seal ring is the pretty troublesome thing of part, and handy measurer is measured continually.It is slide calliper rule that existing seal ring detector is actually measurer, because seal ring is with making as the material of rubber and so on, material is soft and have elasticity in easy deformation radially, slide calliper rule are only applicable to internal diameter less or internal diameter and the smaller seal ring of diameter of section, big or internal diameter and the bigger seal ring of diameter of section are difficult to amount accurately for internal diameter.The inaccurate mistake that usually causes spare parts purchasing of size quantity, for using reliable opinion, the seal ring of adjacent model is all purchased back sometimes, causes unnecessary waste.Moreover, in part warehouse, also can differ very little, often cause confusion, be not easy to management owing to the internal diameter of the seal ring of adjacent model.Producing and selling, keeping, use department at seal ring should have the detector of seal ring accurately simple in structure, easy to use.

(3) summary of the invention

Problem to be solved in the utility model is in order to overcome the above-mentioned deficiency of existing slide calliper rule, provide a kind of easy to use, measure seal ring detector accurately.

Scheme of the present utility model is that the dop with two to four similar slide calliper rule is installed in the scale bar and the Conical Shells With that can slide up and down and combines, and Conical Shells With is propped up seal ring and held round, and dop is in order to the internal diameter of amount seal ring, and the internal diameter of seal ring marks on the scale bar.

The utility model comprises retractable two dops and scale bar, dop is fixed on slide bar, it is characterized in that: one through hole is arranged at scale bar middle part, slide bar inserts in the through hole of scale bar, dop is installed in the scale bar by slide bar, the measurement blade of dop is identical with the direction of scale bar, at the measurement blade of dop cue mark is arranged; A Conical Shells With and pedestal are arranged, and Conical Shells With and pedestal are fixed as one, and the scale bar is installed in Conical Shells With and can slides up and down along the axis of Conical Shells With, and Conical Shells With is stretched out in the upper end of scale bar, and the lower ends downward of scale bar stretches into pedestal; Be provided with and the corresponding groove along the conical surface bus in dop position in Conical Shells With, dop is outside groove stretches out Conical Shells With.

Above-mentioned seal ring detector is characterized in that: the theoretical circular cone height of Conical Shells With equated the end of with.

Above-mentioned seal ring detector is characterized in that: at the middle part of scale bar a through hole is arranged in addition, other has the slide bar of two dops through being inserted in this through hole to be installed in the scale bar and stretches out outside the Conical Shells With, and there is horizontal bayonet lock at the position outside dop stretches out Conical Shells With.

During measurement, seal ring is placed on the Conical Shells With outer surface, the pulling dop makes that circle contacts in dop blade and the seal ring, and manages the cue mark of blade is aimed at the positive middle part of the internal diameter of measured seal ring, by the i.e. internal diameter of sealing circle as can be known of scale that pushes up from Conical Shells With on the scale bar that exposes.

Two to four dops of usefulness of the present utility model are installed in the scale bar and the Conical Shells With that can slide up and down and combine, Conical Shells With is propped up seal ring to hold round and is prevented the seal ring distortion, dop is in order to measure the internal diameter of seal ring, but the seal ring of measurement standandization not only, also can measure off-gauge seal ring, it is accurately convenient to measure, and measurement result can meet the demands.The producing and selling, keeping, the use department that are suitable for seal ring use.

(4) description of drawings

Fig. 1 is that the utility model is implemented the sectional view along the scale rod axis.

Fig. 2 is the partial enlarged drawing of Conical Shells With top and scale bar.
