Abstract
The utility model discloses a tool for measuring concentricity and position of tubular parts with large diameters. The tool is characterized by comprising a T-bar (1), a vertical rod (3) and a dial indicator (4), wherein the lower two ends of the transverse rod of the T-bar (1) are provided with a positioning pin (2) respectively; the dial indicator (4) is arranged on the vertical rod (3); and the vertical rod (3) can be adjusted up and down on the T-bar (1). The tool has a simple structure, is easy to be manufacture, can conveniently measure the concentricity and position, and can also measure the concentricity and position during processing; and when the part is unsatisfactory, adjustment or reworking is performed in time, so that large parts are prevented from being discarded as useless.
Description
Technical field
The utility model relates to a kind of concentricity and position measurement instrument of large tube-like mechanical component.
Background technology
Current engineering drawing shows the right alignment requirement for large tube-like mechanical component custom with the position kilsyth basalt.The current directly instrument or the instrument of measuring position degree do not measured except that using three coordinate measuring engine measurement.Large-scale three coordinate measuring machine is not all configurable expensive equipments of measuring of medium-sized and small enterprises.Committee's external pelivimetry cost height, time-consuming, bothersome, risk in transit and inconvenience are arranged.
Summary of the invention
It is a kind of simple in structure that the purpose of this utility model is to provide, the practical measurement large diameter tubular part concentricity and the instrument of position degree.
The technical solution adopted in the utility model is: a kind of large diameter tubular part concentricity and position measurement instrument, comprise T-bar, montant, clock gauge, two ends respectively are provided with a register pin under the T-bar cross bar, and clock gauge is installed on the montant, and montant is adjustable up and down at T-bar.
The utility model is simple in structure, and oneself is made easily, and measures conveniently, can when finding can not adjust timely or do over again when meeting, avoid scrapping of heavy parts at in-process measurement.
Description of drawings
Fig. 1 is a structural drawing of the present utility model.
Embodiment
As can be seen from Figure 1, T-bar 1 of the present utility model is welding or with a structural member of bolted, two ends respectively are provided with a register pin 2 under the T-bar cross bar, and clock gauge 4 is installed on the montant 3, and montant 3 is adjustable about T-bar.
Using method: T-bar is lain on the tube shape component end face, and register pin is close to circle or cylindrical in the seam, the maximal value and the minimum value of changeing the meter reading of a circle along setting circle.It is exactly concentricity that maximal value subtracts the difference that minimum value obtains.
If measure the position degree of seam circle to cylinder in the cylindrical shell by Unite States Standard (USS), measure an end during measurement earlier, adjusting the vertical rod upper-lower position repeats once, write down the once indicating value of table every 45 degree, with containing in the Excel form that presets formula of the supporting exploitation of record input, just can obtain position degree result.
Claims (1)
1. large diameter tubular part concentricity and position measurement instrument, it is characterized in that: comprise T-bar (1), montant (3), clock gauge (4), two ends respectively are provided with a register pin (2) under T-bar (1) cross bar, clock gauge (4) is installed on the montant (3), and montant (3) is adjustable up and down at T-bar (1).
