Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. All other embodiments, which can be obtained by a person skilled in the art without any inventive step based on the embodiments of the present invention, are within the scope of the present invention.
Examples 1,
As shown in fig. 1, an embodiment of the present invention provides a method for automatically checking a pipeline gap, including:
acquiring a check item in a parameter configuration library;
judging whether the check item is matched with a preset check item;
if so, checking the pipeline clearance of the checking item to obtain clearance checking information;
and outputting a pipeline clearance inspection report containing the clearance inspection information of the inspection item.
Preferably, the performing of the pipeline clearance inspection of the inspection item to obtain the clearance inspection information includes:
checking whether a pipeline clearance value between the pipeline to be detected and a preset pipeline meets the requirement or not by a spherical method;
if so, determining the pipeline clearance value;
otherwise, the product is not qualified.
Preferably, whether the pipeline clearance value of waiting to detect pipeline and predetermined pipeline meets the requirements through the ball method inspection includes:
setting the radius of the detection ball as a preset pipeline clearance value;
moving the center of the sphere along the central axis of the pipeline to be detected;
judging whether the ball is in contact with a preset pipeline or not;
and if not, the pipeline clearance value of the pipeline to be detected and the preset pipeline meets the requirement.
Preferably, determining the line clearance value comprises:
increasing the radius of the ball according to preset precision;
moving the sphere center of the sphere with the increased radius along the central axis of the pipeline to be detected;
judging whether the round ball with the increased radius is in contact with the preset pipeline or not;
if not, increasing the radius of the ball according to preset precision until the ball is contacted with the preset pipeline;
and the radius of the ball in contact with the preset pipeline is the value of the pipeline clearance.
The method proposes to utilize a CREO secondary development platform and adopts a program optimization method to realize automatic checking of the pipeline clearance, wherein one of the measuring methods is as follows: after the three-dimensional pipeline is generated, the pipeline is provided with a central axis, the pipeline is realized by a ball method through a software program, and a ball is set to start along the central axis at one end of the pipeline and quickly pass along the central axis until reaching the central axis at the other end. The radius of the round ball is set to be R1, R1 is a set clearance standard, for example, R1 is 10mm, the clearance standard is 10mm, and as long as the side part is contacted with the round ball, the clearance is not satisfactory. If not, the gap is larger than 10mm, which is satisfactory. Each gap criterion such as R1 may be stored in the parameter configuration library of the server in advance.
The round sphere method adopts R1 in the first sweep, if other parts are not contacted, the clearance is consistent, in order to accurately measure the actual clearance, the round sphere starts the second sweep with the radius of R2, and the radius is increased by delta R, for example, the delta R is 1 mm; if a part is not yet touched, the increase continues, and if other parts are touched, Δ R is decreased until no touch is made. The value of Δ R is the accuracy of the final result and can be 0.1mm or 0.01mm, with values less than 0.01mm being of no great significance. The minimum clearance between the line and other parts over multiple scans can be determined.
As shown in FIG. 2, a round sweep with a radius of Ra indicates that tube 1 and tube 2 are not touching, each time Δ R is increased until a round sweep with a radius of Rb is reached just before tube 1 and tube 2 touch. Rb is the gap value between the tube 1 and the tube 2; as Δ R continues to increase, the Rc radius is reached, the sphere and tube 2 collide and interfere, and the sweep ends. The difference between Rc and Rb is the final precision (which can be changed by software setting, and can be 0.1mm, or 1mm or 2 mm).
Preferably, each section of the pipe 1 and the pipe 2 can have different gaps, the gaps of each section of the pipe can be determined along with scanning, and finally, the minimum gap and the maximum gap are displayed in a list form, so that design and examiner can conveniently and quickly master information.
Preferably, a sphere method can be used to locally scan a designated part, and the minimum clearance between the local curved surface and other parts can be drawn.
