Referring to fig. 1, 2 and 3, a taper detection apparatus includes a fixing member for fixing a product 100 to be detected; the taper detection rubber wheel 330 is internally provided with a pressure sensor 331, and the taper detection rubber wheel 330 is in interference fit with the product 100 to be detected; and the reciprocating driving component is used for driving the taper detection rubber wheel 330 to reciprocate. The product 100 to be tested is a cylindrical piston cylinder, which is generally transparent glass. When taper detection is carried out, a product 100 to be detected is placed in the fixing component for fixing, the reciprocating driving component drives the taper detection rubber wheel 330 to stretch into the product 100 to be detected and carry out linear motion, the pressure sensor 331 in the taper detection rubber wheel 100 starts to carry out pressure detection, because the taper detection rubber wheel 330 is in interference fit with the product 100 to be detected, when a certain taper exists in the product 100 to be detected, the pressure received by the pressure sensor 331 changes, the product 100 to be detected can be judged not to accord with the taper requirement, the measuring efficiency is high, and the use is simple. When the piston cylinder is produced, the inner wall of the piston cylinder cannot be hundred percent smooth and the taper is zero, so a range can be set for the stress change of the pressure sensor 331, when the stress change of the pressure sensor 331 is in the set range, the product 100 to be detected can be regarded as a qualified product, and when the stress change of the pressure sensor 331 exceeds the set range, the product 100 to be detected can be regarded as an unqualified product. The taper angle measuring device further comprises a main control unit which is electrically connected with the pressure sensor 331 and used for receiving pressure signals of the pressure sensor 331, and a touch control screen for displaying pressure applied to the pressure sensor 331, wherein the touch control screen is used for providing intuitiveness in a taper angle measuring process, is connected with each electrical element and is used for displaying pressure information applied to the pressure sensor 331 in real time. When the taper detection is performed, since the taper detection rubber wheel 330 is in interference fit with the product 100 to be detected, when the taper detection rubber wheel 330 just enters the product 100 to be detected, the pressure sensor 331 of the taper detection rubber wheel is subjected to pressure change caused by extrusion differential generation, and therefore when the taper detection rubber wheel 330 just extends into the product 100 to be detected completely, the taper detection is formally performed. In addition, when it is determined that the product 100 to be detected does not meet the taper requirement, the product 100 to be detected may be rotated forward and backward and fixed, then the reciprocating driving assembly drives the taper detection rubber wheel 330 to extend into another opening of the product 100 to be detected and perform linear motion, the pressure sensor 331 in the taper detection rubber wheel 100 starts to perform pressure detection, and if the stress variation of the pressure sensor 331 exceeds the set range, the product 100 to be detected is regarded as an unqualified product.
