[ detailed description ] embodiments
The following is a detailed description of specific embodiments.
The present invention will be described in further detail with reference to the following embodiments. It should be emphasized that the following description is merely exemplary in nature and is not intended to limit the scope of the invention or its application.
As shown in fig. 1-3, a fuel inlet chamfer gauge, circular through-hole has been seted up in the axle center of cylinder handle 1, the threaded hole has been seted up to the lateral wall of cylinder handle 1, threaded hole is equipped with screw 5, be equipped with center pin 2 in the circular through-hole of cylinder handle 1, the lateral wall that center pin 2's bottom was equipped with screw rod center pin 2 has seted up the spacing shallow slot in many places, the digit to different hole depth degree is carved with respectively to the top of spacing shallow slot, the square is distinguished to select the chamfer of detecting the different degree of depth, the top of cylinder handle 1 is equipped with spacing iron sheet 3, the outside of spacing iron sheet 3 is equipped with the arc piece 6 of placing spacing iron sheet 3, the movable slot of placing spacing iron sheet 3 is seted up to arc piece 6 bottom, be equipped with spring 7 in the movable slot of placing spacing iron sheet 3.
The use process comprises the following steps: the cylindrical handle 1 is used as a horizontal reference (a machining tool is worn in the using process, and the machined chamfer is supposed to be smaller), the limiting iron sheet 3 is pulled up, the limiting shallow groove on the side wall of the central shaft 2 is rotated to the position corresponding to the limiting iron sheet 3 and is positioned right above the limiting iron sheet 3, at the moment, the bottom surface of the cylindrical handle 1 is contacted with the top surface of a cylinder cover, the central shaft 2 is pressed downwards, and if the limiting shallow groove of the central shaft 2 is stopped above the limiting iron sheet 3, the chamfer of the hole is proved to be smaller and not meet the machining requirement; if the limiting iron sheet 3 is clamped into the limiting shallow groove through the acting force of the spring, the chamfer of the hole is proved to meet the processing requirement. However, the machined chamfer angle is too large, at this time, if the limit iron sheet 3 is above the limit shallow groove, the chamfer angle is too small and is not needed to be measured, if the limit iron sheet 3 is clamped into the limit shallow groove, the limit iron sheet 3 is only needed to be pulled lightly, the central shaft 2 is pressed downwards, and the limit shallow groove of the central shaft 2 is positioned below the limit iron sheet 3, so that the chamfer angle of the hole is shown to be larger. The whole process only needs 15-20 seconds. After the use, screw on the side of the cylindrical handle 1 is screwed to prevent the central shaft 2 from falling out in the next use.
The utility model only needs to observe whether the limit iron sheet is above or below the limit shallow groove when detecting whether the chamfer is qualified, the detection process only needs 15-20 seconds, and the chamfer detection device is convenient and quick and is suitable for being used in the detection work with quick processing rhythm; the chamfer angle measuring block can be replaced according to the specification of a chamfer angle through threaded connection, the chamfer angle measuring block does not need to be debugged after replacement, the central shaft is provided with limit shallow grooves with different heights aiming at holes with different depths, the universality is strong, the time is saved, the working efficiency is high, and the labor intensity of detection personnel is reduced; low manufacturing cost and strong practicability.
The above description should not be taken as limiting the invention to the specific embodiments, but rather, as will be apparent to those skilled in the art, numerous modifications and variations are possible without departing from the inventive concepts herein disclosed, and it is intended to cover all modifications and variations of the invention as defined by the appended claims.
