[0002] The existing patent (Announcement No.: CN109458908B) proposes a through-and-no-stop gauge inspection fixture structure for inspecting the outer diameter of a steering gear pressure block, in which a connecting rod is installed between the through-gauge and the positioning plate, the no-stop gauge is slidably installed on the connecting rod, and a tension spring sleeved on the connecting rod is provided between the no-stop gauge and the positioning plate; the through-gauge has an inspection inner hole and a pressure block slideway for inspecting the outer diameter of the pressure block, the pressure block slideway is an external extension of the inspection inner hole, and the end of the pressure block slideway is connected to the positioning plate; two through holes are respectively provided on both sides of the inspection inner hole; the no-stop gauge is a large circular inner hole with a notch at the bottom, and the symmetrical right-angled surfaces on both sides of the notch cooperate with the two side planes of the through-gauge pressure block slideway; in this device, a connecting rod is installed between the through-gauge and the positioning plate, and the no-stop gauge is slidably installed on the connecting rod, but the through-gauge and the no-stop gauge of this device can only inspect the outer diameter of the tested piece, but not the inner diameter, and are not flexible enough to use. Summary of the invention

[0003] In view of the above-mentioned deficiencies in the prior art, the utility model provides a test piece that can measure two specifications of internal threaded holes and external threads. The utility model is flexible to use. Compared with the traditional setting in which a through ruler can only measure external threads or internal threads, the utility model is easy to use and can be disassembled and replaced to test the outer diameter of a small steel cap.

[0004] The purpose of this utility model is achieved through the following technical solutions:

[0005] A tool for inspecting the outer diameter of a small steel cap, comprising a hexagonal grip bar, an inner and outer diameter combined go gauge, an inner and outer diameter combined stop gauge, and a positioning clamping column. The hexagonal grip bar has a hexagonal grip bar side hole, and the hexagonal grip bar side holes are symmetrically arranged at both ends of the hexagonal grip bar. The hexagonal grip bar has a reinforcement plug column, and the upper and lower ends of the reinforcement plug column have reinforcement plug column side plates. The side of the inner and outer diameter combined stop gauge has a stop gauge side rod, and the stop gauge side rod is adapted to the hexagonal grip bar side hole, and the stop gauge side rod is inserted into the hexagonal grip bar side hole The stop gauge side rod has an inner hole in the stop gauge side rod, the reinforcement column is adapted to the inner hole in the stop gauge side rod, the reinforcement column is inserted into the inner hole in the stop gauge side rod, the upper and lower ends of the inner hole in the stop gauge side rod have symmetrical inner slots in the stop gauge side rod, the reinforcement column side plate is adapted to the inner slot in the stop gauge side rod, the reinforcement column side plate is inserted into the inner slot in the stop gauge side rod, the inner hole in the stop gauge side rod has a stop gauge side rod hole, the hexagonal grip has a positioning hole, the hexagonal grip has a positioning slot, and the positioning hole corresponds to the positioning slot.

[0006] The reinforcing column has a reinforcing column through hole, the stop gauge side rod hole corresponds to the positioning hole and the positioning slot, the stop gauge side rod hole, the reinforcing column through hole, the positioning hole, and the positioning slot have the same diameters, the circular magnetic sheet is adapted to the positioning slot, the circular magnetic sheet is inserted into the positioning slot, the circular magnetic sheet is connected to the positioning slot, the positioning card column has the same diameter as the circular magnetic sheet, the positioning card column passes through the positioning hole, the stop gauge side rod hole, and the reinforcing column through hole in sequence and is inserted into the positioning slot, and the side surface of the positioning card column fits with the circular magnetic sheet. Beneficial Effects

[0007] 1. The side rod of the stop gauge of the utility model is inserted into the side hole of the hexagonal grip rod, and the side rod of the through gauge is inserted into the side hole of the hexagonal grip rod. The inner and outer diameter combined through gauge, the inner and outer diameter combined stop gauge and the hexagonal grip rod are arranged in a detachable structure. Compared with the integrated structure, the detachable structure is more convenient to replace during use, and it is convenient to inspect the parts to be inspected with holes of different diameters. It is only necessary to exchange a group of inner and outer diameter combined through gauges and inner and outer diameter combined stop gauges of different specifications and sizes. It is easy to use, and the left and right symmetrical reinforcement plug-in column side plates are respectively inserted into the stop gauge side rod inner card slots and the through gauge side rod inner card slots corresponding to the stop gauge side rods and the through gauge side rods. The inner and outer diameter combined through gauge and the inner and outer diameter combined stop gauge are axially positioned by the stop gauge side rods, so that when the through and stop gauge inspection tool is used, the inner and outer diameter combined through gauge and the inner and outer diameter combined stop gauge are prevented from being accidentally moved when the parts to be inspected are inspected. The workpiece to be inspected rotates, making the inspection difficult. The circular magnetic sheet is bonded and fixed in the positioning slot. The positioning column passes through the positioning socket, the side rod hole of the through gauge, and the through hole of the reinforcement column in turn and is inserted into the positioning slot. The inner and outer diameter combined through gauge is positioned by the positioning column. When the through and no-stop gauge inspection tool is in use, the side rod of the through gauge is prevented from slipping out of the side hole of the hexagonal grip rod, thereby ensuring the connection between the inner and outer diameter combined through gauge and the hexagonal grip rod. The circular magnetic sheet prevents the positioning column from slipping out of the positioning slot when the through and no-stop gauge inspection tool is in use, thereby ensuring the position of the positioning column. The positioning column passes through the positioning socket, the side rod hole of the no-stop gauge, and the through hole of the reinforcement column in turn and is inserted into the positioning slot. The inner and outer diameter combined stop gauge is positioned by the positioning column. When the through and no-stop gauge inspection tool is in use, the side rod of the no-stop gauge is prevented from slipping out of the side hole of the hexagonal grip rod, thereby ensuring the connection between the inner and outer diameter combined stop gauge and the hexagonal grip rod.

[0008] 2. The utility model fixes the inner and outer diameter combination through gauge and the inner and outer diameter combination stop gauge at both ends of the hexagonal grip rod through a group of positioning clamps. The inner and outer diameter combination through gauge is a through gauge, and the inner and outer diameter combination stop gauge is a stop gauge. When measuring the internal threaded hole, the inner and outer diameter combination through gauge is screwed into the threaded hole of the measured part. If it can be screwed in smoothly, it is qualified. Otherwise, the hole is too small and needs to be reworked. Then the inner and outer diameter combination stop gauge is screwed into the threaded hole of the measured part. If it can be screwed in smoothly for two turns or more, it is unqualified. Otherwise, it is qualified and the unqualified is reworked. The test piece is directly scrapped and cannot be reworked because the threaded hole is too large. The outer diameters of the inner and outer diameter combined go gauge and the inner and outer diameter combined no-stop gauge are respectively go and no-stop gauges for measuring the internal threaded holes of the test piece, and the inner diameters of the inner and outer diameter combined go gauge and the inner and outer diameter combined no-stop gauge are go and no-stop gauges for measuring the external threads of the test piece. A set of inner and outer diameter combined go gauges and inner and outer diameter combined no-stop gauges can measure two specifications of test pieces, namely internal threaded holes and external threads. They are flexible to use. Compared with the traditional setting where one through gauge can only measure external threads or internal threads, this structure is easy to use and can be disassembled and replaced.
