Abstract
The utility model discloses a device for simultaneously measuring diameters of inner and outer circles. The device comprises an annular base, wherein a cylindrical outer supporting seat is arranged on the base, an upper end surface of the outer supporting seat is provided with a groove and is in clearance fit with an outer circle measuring head, and the outer side of the outer circle measuring head is provided with an outer circle measuring head air inlet nozzle; the base inside the outer supporting seat is provided with a cylindrical inner supporting seat, the upper end of the inner supporting seat is provided with an inner hole measuring head, and an inner hole measuring head air inlet nozzle is arranged at the lower part of the inner hole measuring head; a space for a measured cylindrical component is reserved between the outer supporting seat and the inner supporting seat, and between the outer circle measuring head and the inner hole measuring head; and the outer circle measuring head and the inner hole measuring head are respectively connected with a pneumatic gauge. The device provided by the utility model has simple structure and practical function, can simultaneously measure the diameters of inner and outer circles of the thin-wall cylindrical components, is convenient and efficient to use, and increases the measuring efficiency greatly.
Description
Technical field
The utility model relates to a kind of inside and outside circle diameter simultaneous measuring apparatus.
Background technology
In the world, divide contact to measure and non-contact measurement to the diameter measurement of thin-walled tube kind part because thin-walled tube kind part wall is thin yielding, in the measurement at the scene take non-cpntact measurement-air-gauge as many.Existing air-gauge, internal diameter and external diameter are separately to measure, and to product inspection, just need operation twice, need multiplex personnel.
For reducing inspection cost, the invention provides a kind of new plug jet, single job is finished the internal-and external diameter of thin-walled tube kind part and is measured.This gauge head cooperates with air-gauge, the diameter measurement of the tube kind part that is applicable to produce in enormous quantities.
The utility model content
The utility model purpose is to provide a kind of measurement mechanism that can measure simultaneously the inside and outside circle diameter.
To achieve these goals, the utility model adopts following technical scheme: inside and outside circle diameter simultaneous measuring apparatus, comprise annular base, and base is provided with the outer support of tubular, the outer support upper surface is provided with groove and clearance fit has the cylindrical gauge head, and the cylindrical gauge head outside is provided with cylindrical gauge head admission piece; Base in the outer support is provided with the interior bearing of tubular, and the upper end of interior bearing is provided with the endoporus gauge head, and the below of endoporus gauge head is provided with endoporus gauge head admission piece; Between outer support, cylindrical gauge head and the interior bearing, tested tube kind part headspace is set between the endoporus gauge head; Cylindrical gauge head, endoporus gauge head are connected with air-gauge respectively.
The pipeline that endoporus gauge head admission piece connects passes successively interior bearing middle part and the base middle part arranges.
Be bolted between outer support and the base.
Base is that interference fit is connected with interior bearing.
Simple in structure, the practical function of the utility model can be measured the inside and outside circle diameter simultaneously to the thin-walled tube kind part, and it is quick to be easy to use, and greatly improves and measures efficient.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
Embodiment: as shown in Figure 1, inside and outside circle diameter simultaneous measuring apparatus comprises annular base 5, and base 5 is provided with the outer support 6 of tubular, and outer support 6 upper surfaces are provided with groove and clearance fit has cylindrical gauge head 7, and cylindrical gauge head 7 outsides are provided with cylindrical gauge head admission piece 8; Base 5 in the outer support 6 is provided with the interior bearing 3 of tubular, and the upper end of interior bearing 3 is provided with endoporus gauge head 2, and the below of endoporus gauge head 2 is provided with endoporus gauge head admission piece 9; Between outer support 6, cylindrical gauge head 7 and the interior bearing 3, tested tube kind part 1 headspace is set between the endoporus gauge head 2; Cylindrical gauge head 7, endoporus gauge head 2 are connected with air-gauge respectively.The pipeline that endoporus gauge head admission piece 9 connects passes successively interior bearing 3 middle parts and base 5 middle parts arrange.Fixing by bolt 4 between outer support 6 and the base 5.Base 5 is connected for interference fit with interior bearing 3.
Before measuring part, first cylindrical gauge head 7 is taken off, with check and correction post check and correction cylindrical gauge head 7; Then, endoporus gauge head 2 is motionless, with check and correction ring check and correction endoporus gauge head 2.Check and correction finishes, and cylindrical gauge head 7 is installed on the outer support 6, just can measure part.
