This utility model is in order to solve to use existing detection method to there is artificial range estimation error when detecting the molded line slope of bias type race greatly, and the problem that can not detect molded line linearity, it is provided that a kind of turbine rotor bias type wheel slot milling molded line detecting device.
This utility model adopts the technical scheme that to solve above-mentioned technical problem: turbine rotor bias type of the present utility model wheel slot milling molded line detecting device includes strip key and two L shaped plates, strip key is parallelepiped structure, the two ends of strip key are affixed with the minor face plate bottom surface of a L shaped plate respectively, the long side plate lateral surface of two L shaped plates and one of them side of strip key are generally aligned in the same plane, acute angle between acute angle between the incline of strip key and horizontal direction and detection groove and the horizontal direction on existing impeller is equal, the longitudinal section width of strip key is equal with the width of detection groove, strip key length is equal with the length of detection groove；
L shaped plate include rectangular slab and arc plate, rectangular slab and arc plate vertical affixed and make one, the two ends of strip key are affixed with a rectangular slab respectively.
The beneficial effects of the utility model are:
1, acute angle between acute angle between incline and the horizontal direction of strip key of the present utility model and detection groove and the horizontal direction on existing impeller is equal, the longitudinal section width of strip key is equal with the width of detection groove, strip key length is equal with the length of detection groove, when detecting bias type race, only need to by manufactured detection groove on strip key embedding impeller, if strip key closely cooperates with detection groove, and the two sides of two L shaped plates and impeller are adjacent to, not bite, then prove that molded line linearity and the slope of machined bias type race are all qualified, accuracy of detection is high, ensure that drawing technology requirement；
2, this utility model simple in construction, manufactures easily, and cost is low, it is simple to promote the use of on a large scale；
3, the easily operated use of this utility model, requires low to the technical merit of testing staff, and detection efficiency is high.
