The outer part of the inspection sleeve is cylindrical, an inner hole is divided into a positioning part and a guiding part, and the positioning part and the guiding part are concentric inner cylinders.
The diameter of the guide part is the same as the diameter of the shaft of the three-pin frame, and the positioning part is a stepped hole.
The go-no go gauge comprises a positioning shaft, a go-no go gauge, a no go gauge and a handle, the positioning shaft, the go-no go gauge, the no go gauge and the handle are concentric cylinders, and knurling is arranged on the surface of the handle.
The diameter of the positioning shaft is the same as that of the middle hole of the tripod head, and the length of the positioning shaft is 2/3 of the thickness of the middle hole.
The utility model discloses profitable effect is: the utility model discloses low in manufacturing cost, simple operation, detection efficiency of structure are high, have replaced large-scale projecting apparatus, and the production site of being convenient for uses.

Description of reference numerals: the testing device comprises a testing sleeve 1, a go-no-go gauge 2, a guide part 3, a positioning part 4, a positioning shaft 5, a handle 6, a go-no-go gauge 7, a no-go gauge 8, a three-pin frame 9, a middle hole 10 and a shaft diameter 11.
Detailed Description
The present invention will be further explained with reference to the accompanying drawings:
as shown in the figure, the special checking fixture for the distance from the center of the hole of the three-pin bracket to the measuring point of the shaft neck mainly comprises a checking sleeve 1 and a go-no-go gauge 2, wherein the checking sleeve 1 is sleeved on the shaft diameter 11 of the three-pin bracket 9, the go-no-go gauge 2 is inserted into a middle hole 10 of the three-pin bracket 9, and the checking sleeve 1 and the go-no-go gauge 2 are vertically matched with each other.
The outside of the inspection socket 1 is cylindrical, the inner bore is divided into a positioning portion 4 and a guide portion 3, and the positioning portion 4 and the guide portion 3 are concentric inner cylinders. The diameter of the guide part 3 is the same as the outer diameter of the shaft diameter 11 of the tripod 9, and the guide part is assembled on the shaft diameter 11 of the tripod 9 to play a centering role in use. The positioning part 4 is a stepped hole and has higher perpendicularity with the end face D.
The go-no go gauge 2 comprises a positioning shaft 5, a go gauge 7, a no go gauge 8 and a handle 6, the positioning shaft 5, the go gauge 7, the no go gauge 8 and the handle 6 are concentric cylinders, the four parts are different in function, the diameter of the positioning shaft 5 is the same as the diameter of a middle hole 10 of the three-pin frame 9, the length of the positioning shaft is 2/3 with the thickness of the middle hole 10, and the positioning shaft plays a centering role. The gauge 7 has a high coaxiality with the positioning shaft 5, a diameter designed for the lower tolerance of the dimension to be checked, and a length less than 1/2 for checking the thickness of the sleeve 1 for checking whether the dimension B exceeds the lower tolerance. The stop gauge 8 has a high coaxiality with the positioning shaft 5, and the diameter is designed according to the upper difference of the detected size and is used for detecting whether the size B exceeds the upper difference. The handle 6 is a hand-held part, and the surface of the handle is provided with knurls, so that the operation is convenient.
When the inspection sleeve is used, the inspection sleeve 1 is tightly arranged on the shaft diameter 11 to be detected, then the go-no-go gauge 2 is placed in the middle hole 10 of the three-pin frame 9, if the go-no-go gauge 7 can smoothly pass through the inspection sleeve 1 and the no-go gauge 8 cannot pass through the inspection sleeve 1, the inspection sleeve is qualified in size, otherwise, the inspection sleeve is unqualified in size.
The utility model simulates the diameter of the measuring point which is difficult to be positioned by using the inspection sleeve with the same diameter, and uses the coaxial inner hole to be matched with the outer circle of the three-pin frame shaft diameter, thereby ensuring that the diameter positioned on the sleeve is vertical to the center of the three-pin frame shaft diameter; the step hole in the sleeve is vertical to the end face, and the diameter position of the measuring point can be converted to the end face; and low in manufacturing cost, simple operation, detection efficiency height. Replaces a large projector and is convenient to use in the production field. The problem of current inspection latency is long is solved. Convenient operation, detection are swift, are applicable to batch production.
