Abstract
The utility model provides a gauge for machining and detecting grooves at pipe ends, comprising a detecting part; and the detecting part has a conical shape, and the taper is the internal groove angle of the pipe end. Two circumference lines are drawn on the conical surface respectively so as to represent the two limit dimensions of the pipe end D1. Extremely high hardness is obtained on the surface of the gauge by high-frequency quenching; therefore, the gauge has high wearability, and is exact in measurement, and high in efficiency.
Description
Technical field
The utility model relates to a kind of pipe end groove processing detection gauge, and check pipe end groove processing dimension belongs to field of mechanical technique.
Background technology
There is a large amount of tubing need dock welding in the station boiler product, comprises welding and building site welding in the factory.In order to guarantee welding quality and concentricity, pipe end need process inside and outside groove angle and D1 size (seeing figure), and the D1 dimensional tolerance range is generally at 0.05～0.1mm.The operator needs constantly to measure the D1 size with vernier caliper and whether meets the drawing tolerance in the process of finished edge before, but can only rely on equipment and cutting-tool angle to guarantee for inside and outside groove angle.Have two problems like this: 1) measurement accuracy problem, because margin tolerance is less, D1 can occurs and measure inaccurate situation, equipment precision decline or tool sharpening angle all can influence the accuracy of machined surface angle in addition.2) the surveying work amount is big, and groove quantity is many, need constantly examine the D1 size, and efficient is low.The overproof problem of D1 occurs if arrived the tubing in building site, will increase very big reclamation work amount, even can incur loss through delay the completion time of project.
Summary of the invention
The utility model provides a kind of gauge of checking pipe end groove size, and measurement is accurate, efficient is high.
A kind of pipe end groove processing detects uses gauge, and comprising: the test section is characterized in that: the test section is the circular conical surface shape, and tapering is a pipe end internal groove angle.On the conical surface, be decorated with two circumferences respectively and represent two dimension limits of pipe end D1.
Pipe end groove processing of the present utility model detects and can obtain very high hardness through high-frequency quenching with the gauge surface, has high-wearing feature.
During large-sized station boiler is made, need bevelled number of tubes a lot, use this instrument and can greatly simplify inspection of groove, save great amount of manpower and man-hour, measure accurately, the efficient height has reduced cost widely, has very big economic benefit.

Embodiment
Below in conjunction with specific embodiment the utility model is carried out specific description.
As shown in Figure 2,1-tubing, 2-gauge.
Gauge is packed in the internal groove of having processed, observe the pipe end place whether in two dimension limit lines.If, illustrate that then D1 is of the required size; As less than minimum limit of size line, then illustrate and processed D1 less than nominal size; If surpass the maximum limit of size line, illustrate that then the D1 size is greater than nominal size.
Claims (1)
1. the processing of pipe end groove detects and uses gauge, comprises the test section, and it is characterized in that: the test section is the circular conical surface shape, and tapering is a pipe end internal groove angle, is decorated with two dimension limits that two circumferences are represented pipe end (D1) on the conical surface respectively.
