Detailed Description
The following description is made with reference to the accompanying drawings and examples, but not to be construed as limiting the invention.
The embodiment is as follows: a bore wear inspection gauge is shown in figure 1 and comprises a sleeve 1, a positioning assembly is arranged on the end face of the sleeve 1, as shown in figures 4 and 5, the positioning assembly comprises a mounting column 5 connected with the end face of the sleeve 1, a cavity 13 is formed in the middle of the mounting column 5, a connecting arm 6 is arranged in the circumferential direction of the mounting column 5, a positioning plate 7 is arranged at the end of the connecting arm 6, an arc face 701 is arranged on the surface of the positioning plate 7, and the arc face 701 is arranged to increase the contact surface of the positioning plate 7 and a bore, so that the stability of the device in moving in the bore is improved; as shown in fig. 2, a push-pull rod 2 is arranged inside the sleeve 1, one end of the push-pull rod 2 penetrates through a cavity 13 and is rotatably connected with a lantern ring 8, as shown in fig. 3, an installation groove 11 is formed in the end portion of the push-pull rod 2, an installation block 12 is arranged on the side portion of the lantern ring 8, the installation block 12 extends into the installation groove 11 and is rotatably connected with the inner wall of the installation groove 11 through a rotating shaft 10, an inspection rod 9 is arranged inside the lantern ring 8, a hemispherical surface is arranged at the end portion of the inspection rod 9, the contact point between the inspection rod 9 and the inner wall of the bore is reduced, and the tail end of the inspection rod 9 can enter a small hollow part of the inner wall of the bore, so that the detection accuracy is improved; one end of the push-pull rod 2, which is far away from the lantern ring 8, extends out of the sleeve 1 and is connected with a pull ring 3; the surface of the positioning component is provided with two clamping grooves 4, the caliber of each clamping groove 4 is matched with the diameter of the tangent plane of the inspection rod 9, and the two clamping grooves 4 are perpendicular to each other; the cavity 13 is located at the intersection of the two card slots 4.
In practical application, two different sizes of the check rod 9 are designed, wherein the length of the shorter check rod 9 is equal to the length of the inner diameter of a standard bore, and the length of the longer check rod 9 is equal to the length of the inner diameter of the bore in a state of being worn to the limit.
The working principle is as follows: when the bore diameter of the gun bore is checked by using the shorter checking rod 9, the checking rod 9 and the positioning assembly are extended into the gun bore together, and the positioning plate 7 of the positioning assembly is attached to the inner wall of the gun bore, so that the middle part of the checking rod 9 can be always kept in the middle of the gun bore. Pull ring 3 is pulled backward, drive push-and-pull rod 2 and remove backward, thereby drive lantern ring 8 and inspection rod 9 and remove, make in inspection rod 9 block advances recess 4, at this moment, inspection rod 9 is in the vertical state, then adjust the position of whole device in the bore, if inspection rod 9 can both ends contact with the bore inner wall all the time under the vertical state, then the bore that indicates the bore accords with the design standard, if inspection rod 9 can't pass through or when both ends can't contact with the bore inner wall simultaneously with vertical state, then indicate that the bore internal diameter does not accord with the design standard.
When the bore diameter of the bore is inspected by using the longer inspection rod 9, the pull ring 3 is pushed forwards firstly, the push-pull rod 2 is driven to move forwards, at the moment, the inspection rod 9 can rotate relative to the push-pull rod 2, and the inspection rod 9 can enter the bore in an inclined state. After the device extends into the bore, the pull ring 3 is gradually pulled backwards, the position of the device in the bore is adjusted, if the inspection rod 9 can completely enter the groove 4 to be in a vertical state, and both ends of the inspection rod can be in contact with the inner wall of the bore, the abrasion degree of the part of the bore reaches the limit, and maintenance is needed; if the two ends of the inspection rod 9 cannot be simultaneously contacted with the inner wall of the bore after completely entering the groove 4, the abrasion degree of the part in the bore is over the limit degree; if the inspection stick 9 cannot pass through the inside of the bore in a vertical state at every position, it means that the wear of the inner wall of the bore has not reached the limit state at every position.
In the inspection process, the degree of wear can be estimated according to the degree of inclination of the inspection rod 9 when passing through the bore, and the larger the degree of inclination of the inspection rod 9 is, the smaller the degree of wear of the inner wall of the bore is, and the smaller the degree of inclination of the inspection rod 9 is, that is, the closer the inspection rod 9 is to the vertical state, the more serious the degree of wear of the inner wall of the bore is. The degree of inclination of the inspection rod 9 can be judged according to the distance of outward drawing of the push-pull rod 2, so that a worker can judge the degree of wear of the inner wall of the bore according to the distance of outward drawing of the push-pull rod 2. In addition, the worn part in the bore can be judged according to the whole device or the distance of the sleeve 1 extending into the bore. The above-mentioned verticality and inclination of the inspection rod 9 are referred to the push-pull rod 2.
Through the operation, the abrasion degree of the inner wall of the bore can be more conveniently checked, whether the abrasion degree of the inner wall of the bore reaches the limit is judged, and the abrasion degree of the inner wall of the bore can be estimated according to the inclination degree of the inspection rod 9 or the outward drawing distance of the push-pull rod 2.
