Abstract
The utility model discloses a novel casing duct detection device. The novel casing duct detection device comprises a passageway coordinate templet (1), a switching block (2) and a positioning block (3) which is fixed at a top end of the switching block (2) through screws B (5), wherein a left end of the passageway coordinate templet (1) is inserted in a groove of a lower end of the switching block (2) and is fixed through screws A (4), the positioning block (3) is an arc-shaped thin plate, and a diameter phiA of an inner side arc is identical to an external diameter of a port of a part to be detected. The novel casing duct detection device has advantages of simple structure, reasonable and accurate positioning, high precision, low processing difficulty, easy manufacturing and good economic performance and can realize smooth detection and obviously shorten detection time for a semi-sealed chamber which can not employ three-coordinate detection or a special passageway which is narrow, fine and long.
Description
Technical field
The utility model relates to aeromotor flow-paths inspection technical field, is specifically related to a kind of novel casing duct pick-up unit.
Background technology
In recent years, high precision runner processing technology is widely used in aeromotor is produced as an advanced and mature technology, and intermediary's casing is contained the flow diameter size outward and do not waited from tens millimeters to several thousand millimeters, and wall thickness only has several millimeters, and difficulty of processing is large.But, at present, for the polishing of outer culvert runner, great majority adopt some manual job operations, the part that these methods process, quality and accuracy detection become a difficult problem, and some position adopts three coordinates to check, but efficient is extremely low, cycle is long, but in semiclosed chamber or the special-shaped flow passage of runner narrow elongate, three coordinates can't detect, and are difficult to guarantee size and the position technique conditional request of External Shape.
The utility model content
The purpose of this utility model is to provide a kind of novel casing duct pick-up unit, in order to solve in prior art the detection difficult problem of the special-shaped flow passage that can't detect by three-dimensional, effectively guarantees aeromotor flow-paths inspection physical dimension precision.
The purpose of this utility model is achieved by following technical solution:
A kind of novel casing duct pick-up unit, it comprises runner coordinate model, transfer block and is fixed on the locating piece on described transfer block top through screw B, be fixed with screw A after in the groove of the described runner coordinate model left end described transfer block of insertion lower end, described locating piece is the circular arc thin plate, and inner arc diameter phi A is identical with the port outside diameter of tested part.
Described runner coordinate model is the rectangle thin plate, and the upper end is provided with chamfering.
Described locating piece and runner coordinate model are perpendicular.
Described transfer block is connected and fixed rear upper surface with fixed block and flushes.
Described screw A, screw B have four respectively.
Compared with prior art, the novel casing duct pick-up unit that the utility model provides, it is simple in structure, and reasonable positioning is accurate, precision is high, and difficulty of processing is low, is easy to make good economy performance; For the semiclosed chamber that can't adopt three traditional coordinates to detect or the special-shaped flow passage of runner narrow elongate, pick-up unit provided by the invention also can detect smoothly, and obviously shorten detection time.

-0.01) fit with the port outside diameter diameter of tested part, port outside diameter along tested part is slided, and meanwhile, runner coordinate model 1 is fitted with the profile of detected runner, by checking the gap of detected runner and runner coordinate model 1, within its measuring accuracy can reach 0.01mm.Along with the rotation of part, can check on full runner arbitrary section.
Embodiment 2: detected part by-pass air duct end face external diameter is φ 376
+ 0.01, duct runner coordinate is of a size of following table:
The locating piece 3 of the pick-up unit that the utility model is provided fits by base plane and tested part end face, its inner arc Φ A=(φ 876
-0.01) fit with the port outside diameter diameter of tested part, port outside diameter along tested part is slided, and meanwhile, runner coordinate model 1 is fitted with the profile of detected runner, by checking the gap of detected runner and runner coordinate model 1, within its measuring accuracy can reach 0.01mm.Along with the rotation of part, can check on full runner arbitrary section.
After adopting pick-up unit that the utility model provides to detect part, its qualification rate is brought up to present 98% from original 10%, and ten hour shorten to half an hour by each original part detection time, and detection efficiency improves 20 times.Guarantee the delivery cycle of part, reduced processing cost.
