Abstract
The utility model relates to a device for measuring dimensions of soft sealing rings, which can simply and visually realize measurement with higher precision. A measuring shaft which has the characteristic of smaller conicity is used as a main body. A small end head part of a conicity measuring shaft is mechanically connected with a kuppe which has convenient disassembly and is in clearance fit with the conical surface of the conicity measuring shaft. The inner part of the conicity measuring shaft is provided with a drainage small hole which is communicated with a gap. Through a passage, gas stream is used for shaping and positioning a measured sealing ring. Then a universal measuring tool is used for measuring the position and the height of the measured sealing ring. Consequently, the dimension of the inner diameter of the measured sealing ring can be calculated according to the functional relationship of the height and the diameter of the conicity measuring shaft.
Description
Affiliated technical field
The utility model is a kind of soft attitude O-ring seal size detecting device, can realize the soft attitude O-ring seal size detection of degree of precision easy, intuitively.
Background technology
Because soft attitude O-ring seal shape is unfixing, very responsive to ergometry, therefore directly bigger with method measuring error such as slide calliper rule, feeler gauges, and there are shortcomings such as complex structure, troublesome poeration in more existing shapings and measurement mechanism.
Summary of the invention
In order to overcome existing soft attitude O-ring seal size detecting device complex operation or the lower deficiency of precision, the utility model provide a kind of easy, directly perceived, precision is higher, measure the pick-up unit of soft attitude O-ring seal size cheaply.
The technical scheme that its technical matters that solves the utility model adopts is: with a measurement axis with less taper feature as main body, its outside diameter is greater than the last tolerance of measured seal ring internal diameter, end diameter is less than the following tolerance of measured seal ring, small end head at the taper measurement axle, the conical surface clearance fit of one of mechanical connection and taper measurement axle can be for convenience detach kuppe, the inside of taper measurement axle is provided with the drainage aperture, and is communicated with this gap.After measured seal ring is put into from taper measurement axle small end, connect kuppe, introduce air-flow, make air-flow blow to measured seal ring, measured seal ring is carried out shaping, location, utilize the universal measurement instrument to measure the measured seal ring position height then, thereby, calculate the internal diameter size of measured seal ring according to the funtcional relationship of taper measurement axle height with diameter.
The beneficial effects of the utility model are: the measuring accuracy to soft attitude O-ring seal is higher, easy and simple to handle, directly perceived, and cost is lower.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is the longitudinal profile structural map of embodiment of the present utility model.
Among the figure: 1. taper measurement axle, 2. kuppe, 3. measured seal ring.
Embodiment
In embodiment illustrated in fig. 1, taper measurement axle (1) has the feature of the male cone (strobilus masculinus) of a less tapering, its outside diameter is slightly larger than the last tolerance of measured seal ring (3) internal diameter, end diameter is slightly less than the following tolerance of measured seal ring (3), the small end head of taper measurement axle (1) and kuppe (2) mechanical connection, constitute the water conservancy diversion gap, the inner drainage aperture of taper measurement axle (1) is communicated with this gap.
Claims (1)
1. soft attitude O-ring seal size detecting device, main body is the taper measurement axle, it is characterized in that: the kuppe of one of the small end mechanical connection of taper measurement axle and the conical surface clearance fit of taper measurement axle, the inside of taper measurement axle is provided with the drainage aperture, is communicated with this gap.
