Description

Technical Field

[0001] The utility model relates to the technical field of measuring tools, in particular to a twelve-hole position measuring gauge for a reducer housing. Background Art

[0002] The reducer housing is an important component installed on the axle housing. The reducer housing consists of a housing, a flange on the edge of the housing and a middle mounting plate. The front and rear edges of the flange respectively extend out convex corner skirts. The reducer housing is provided with structural holes such as an axial hole, a middle mounting hole and a through hole on the side wall of the housing. There are 12 through holes on its flange, which are used to bolt the reducer housing and the rear axle housing into an assembly after the rear axle housing is assembled. After the reducer housing is cast, the flange needs to be drilled. After the drilling, a measuring gauge needs to be used to measure the position of the twelve mounting holes processed on the reducer housing. The position requirement of the twelve through holes on the reducer housing is φ0.3.

[0003] In the Chinese patented mounting hole position measuring gauge for mounting brake discs on EMU wheels (patent number: CN215177414U), the device includes a ring-shaped body, on which 18 positioning holes are arranged at intervals, the centers of the positioning holes are located on the same circle, and the positioning holes correspond to the positions of the mounting holes on the EMU wheels to be measured; a hollow cylinder is fixed at each positioning hole, the two ends of the hollow cylinder are open, the annular inner side surface of the hollow cylinder is aligned with the annular inner side surface of the positioning hole, and the axis of the hollow cylinder is parallel to the axis of the body; at least 3 are arranged at intervals on the ring-shaped body Support columns, each support column is connected with a connecting edge, one end of each connecting edge is connected to the same positioning ring, the positioning ring is coaxial with the body, and the inner diameter of the positioning ring is equal to the inner diameter of the central reference hole of the EMU wheel to be measured; the hollow cylindrical tube and the support column are located on the same side of the body. The device has the advantages of easy use, low manufacturing and testing costs, etc. However, the device needs to insert the positioning pins into the hollow cylindrical tube of the positioning hole one by one to measure the twelve hole positions of the shell. The operation steps are relatively cumbersome, wastes manpower, affects the measurement efficiency, and there are a large number of movable measuring pins, which are easy to lose, affecting subsequent use.

[0014] 1. The reducer housing twelve-hole position measuring gauge is provided with a measuring gauge body, a detection through hole, a lifting ring, a measuring pin and a lifting adjustment mechanism. When using the device to measure the twelve-hole position of the reducer housing, first assemble the detection through hole on the measuring gauge body with the positioning outer circle on the reducer housing flange, and then rotate the threaded rod.

[0021] See also Figures 1 to 3In the present practical embodiment, the reducer housing twelve-hole position measuring gauge comprises a measuring gauge body 1 arranged in a circular centroid structure and a lifting ring 2 located directly above the measuring gauge body 1. The side wall of the measuring gauge body 1 is provided with twelve detection through holes 3 arranged corresponding to the twelve hole positions of the reducer housing. A lifting adjustment mechanism is fixedly connected to one side of the measuring gauge body 1, and one end of the lifting adjustment mechanism is fixedly connected to the lifting ring 2. A positioning mechanism is fixedly connected to the side of the measuring gauge body 1 away from the lifting adjustment mechanism, and one end of the positioning mechanism is fixedly connected to the lifting ring 2. Twelve measuring pins 4 arranged corresponding to the detection through holes 3 are fixedly connected to the lower side wall of the lifting ring 2 to prevent the measuring pins 4 from being lost. When in use, first assemble the detection through holes 3 on the measuring gauge body 1 with the positioning outer circle on the reducer housing flange, and then operate the lifting adjustment mechanism to drive the lifting ring 2 to move downward. If the twelve measuring pins 4 are successfully inserted, it can be judged that the position of the twelve mounting holes on the reducer housing flange is qualified. If the twelve measuring pins 4 cannot be successfully inserted, it means that the position of the twelve holes of the reducer housing exceeds the required Φ0.3, and this hole is judged to be unqualified.

[0022] Easy to operate, and the parts are simple and easy to buy, low cost and easy to maintain;

[0023] The lifting and lowering adjustment mechanism includes a fixed plate 5 fixed on one side of the measuring gauge body 1, and the upper side wall of the fixed plate 5 is rotatably connected to a threaded rod 6 through a rotating member, and a nut block 8 is threadedly connected to the threaded rod 6. A connecting block 9 is fixedly connected to one side of the nut block 8, and one end of the connecting block 9 is fixedly connected to the lifting ring 2. After assembly, the threaded rod 6 is rotated. At this time, the nut block 8 is forced to move downward, thereby driving the lifting ring 2 fixed with the connecting block 9 to move downward, so that the twelve measuring pins 4 are inserted into the detection through hole 3 at the same time. Compared with inserting the measuring pins 4 one by one, this operation is more convenient, and the efficiency of measuring the twelve hole positions of the reducer housing is improved.

[0024] like Figure 1 and Figure 2 As shown: the positioning mechanism includes a mounting plate 10 fixed on one side of the measuring gauge body 1, a positioning rod 11 is fixedly connected to the upper side wall of the mounting plate 10, a sliding sleeve 12 is sleeved and slidably connected to the positioning rod 11, a positioning block 13 is fixedly connected to one side of the sliding sleeve 12, and one end of the positioning block 13 is fixedly connected to the lifting ring 2. When the lifting ring 2 is displaced, the sliding sleeve 12 fixed to the positioning block 13 is driven to slide and displace on the positioning rod 11, which can play a role in positioning and guiding the displacement of the lifting ring 2, thereby ensuring the straight up and down displacement of the lifting ring 2.

[0025] like Figure 1 As shown: the upper end of the positioning rod 11 is fixedly connected to a limit stopper 14 to prevent the sliding sleeve 12 from separating from the positioning rod 11.

[0026] like Figure 1 As shown: the upper end of the threaded rod 6 is fixedly connected with a hand wheel 7 to facilitate the rotation of the threaded rod 6.

[0027] like Figure 1 As shown: the side walls of the measuring gauge body 1 are fixedly connected with two symmetrically arranged handles 15 through fasteners, so as to facilitate the assembly of the device with the flange of the reducer housing.

[0028] like Figure 3 As shown: the upper side wall of the measuring gauge body 1 is fixedly connected with a bushing 16 which is connected with the detection through hole 3 and is easy to insert.

[0029] like Figure 3 As shown: the lifting ring 2 is detachably connected to the measuring pin 4 via a fixing bolt 17 and can be replaced.

[0030] Working principle: When using this device to measure the positions of the twelve holes of the reducer housing, first assemble the detection through hole 3 on the measuring gauge body 1 with the positioning outer circle on the reducer housing flange, and then rotate the threaded rod 6. Since the threaded rod 6 is threadedly connected to the nut block 8, at this time, the nut block 8 is forced to move downward, thereby driving the lifting ring 2 fixed with the connecting block 9 to move downward, so that the twelve measuring pins 4 are inserted into the detection through hole 3 at the same time. Compared with inserting the measuring pins 4 one by one, this operation is more convenient, and the efficiency of measuring the positions of the twelve holes of the reducer housing is improved. If the twelve measuring pins 4 are successfully inserted, it can be judged that the positions of the twelve mounting holes on the flange of the reducer housing are qualified. If the twelve measuring pins 4 cannot be successfully inserted, it means that the positions of the twelve holes of the reducer housing exceed the required Φ0.3, and it is judged that the holes of this reducer housing are unqualified. The operation is convenient. Secondly, when the lifting ring 2 is displaced, it drives the sliding sleeve 12 fixed with the positioning block 13 to slide and displace on the positioning rod 11, which can play a positioning and guiding role in the displacement of the lifting ring 2, and ensure the straight up and down displacement of the lifting ring 2.
