Description

Technical Field

[0001] This utility model relates to a positioning and measuring fixture for machining the oil groove hole of a ring groove nut, belonging to the field of nut machining and measurement technology. Background Technology

[0002] For ring groove nuts with oil groove holes on the side that connect to internal threaded through holes, when drilling the oil groove holes, the ring groove nuts need to be clamped and fixed, and then the oil groove holes are drilled using a drill bit.

[0003] Existing nut drilling technology, as described in Chinese Patent Publication No. CN216461926U, allows for positioning of the nut in six radial directions through clamping support. However, it cannot be used to position the annular groove nut, nor can it quickly locate the position of the oil groove hole. Summary of the Invention

[0004] To solve the above-mentioned technical problems, this utility model provides a positioning and measuring fixture for machining the oil groove hole of an annular nut.

[0005] This utility model is achieved through the following technical solution.

[0006] This utility model provides a positioning and measuring fixture for machining the oil groove hole of a ring groove nut, comprising: A tooling fixture for completing the drilling, positioning, and measurement processes using the oil groove hole on the auxiliary ring groove nut.

[0007] The tooling body is a rectangular block.

[0008] The tooling body has a tooling groove at the front end that accommodates three six-sided tooling grooves for the ring groove nut; the three sides of the tooling groove are all square surfaces, which contact the corresponding six-sided surfaces of the ring groove nut.

[0009] It also includes a grooved nut with a regular hexagonal section and a round shaft section. The grooved nut is placed in contact with the tooling body, and the three six-sided sections of the regular hexagonal section contact the tooling groove. The regular hexagonal section of the grooved nut is radially positioned.

[0010] The tooling body located at the rear side of the tooling groove is provided with an arc groove, which forms a step with the tooling groove and is connected. The arc groove only accommodates the round shaft section that contacts the annular groove nut. The arc groove is closed by a sealing surface, which contacts the end face of the round shaft section for positioning.

[0011] The tooling body on the side of the tooling slot is provided with a guide hole.

[0012] The regular hexagonal section is provided with a fuse hole and an oil groove hole; the axes of the fuse hole and the oil groove hole are projected onto the end face of the circular shaft section at an angle α.

[0013] The α is 30°; the fuse hole extends through a regular hexagonal section.

[0014] The annular groove nut has an internal threaded through hole, and the oil groove hole is connected to the internal threaded through hole.

[0015] The beneficial effects of this utility model are as follows: when the ring groove nut is placed in the tooling groove, three of the six-sided sections are radially positioned within the tooling groove, and the round shaft section is positioned within the arc groove. The end face of the round shaft section contacts the closed surface for positioning, thus solving the problem that the prior art cannot position the ring groove nut during processing.

Detailed Implementation

[0017] The technical solution of this utility model is further described below, but the scope of protection is not limited to what is described.

[0018] like Figures 1 to 5 As shown.

[0019] This application discloses a positioning and measuring fixture for machining the oil groove hole of a ring groove nut, comprising: The tooling body 1 is a rectangular block. The front end of the tooling body 1 is provided with a tooling groove 11 that accommodates three six-sided tooling grooves 11 for the annular groove nut 2. The three sides of the tooling groove 11 are all square surfaces, which contact the corresponding six-sided surfaces of the annular groove nut 2. When the three six-sided surfaces of the annular groove nut 2 contact the tooling groove 11, the hexagonal segment 21 of the annular groove nut 2 is radially positioned.

[0020] The tooling body 1 at the rear side of the tooling groove 11 is provided with an arc groove 12. The arc groove 12 forms a step with the tooling groove 11 and is connected, so that the arc groove 12 only accommodates the round shaft section 22 that contacts the annular groove nut 2. The arc groove 12 is closed by a sealing surface 13, and the sealing surface 13 contacts the end face of the round shaft section 22 for positioning.

[0021] When the annular groove nut 2 is placed in the tooling groove 11, three of the six-sided sections 21 are radially positioned within the tooling groove 11, and the circular shaft section 22 is positioned within the circular arc groove 12. The end face of the circular shaft section 22 contacts the closed surface 13 for positioning, thus solving the problem that the existing technology cannot position the annular groove nut during machining.

[0022] At this point, the position of the oil groove hole 24 to be drilled on the grooved nut 2 can be quickly aligned with the guide hole 14 on the tooling body 1, while the fuse hole 25 of the grooved nut 2 faces upward. The tooling body 1 with the grooved nut 2 is clamped and fixed on the drilling machine, and the drill bit drills the oil groove hole 24 through the guide hole 14.

[0023] The fuse hole 25 and the oil groove hole 24 are distributed at an angle α when projected onto the end face of the circular shaft section 22, where α can be selected as 30°; the fuse hole 25 penetrates the regular hexagonal section 21. Before drilling the oil groove hole 24, the fuse hole 25 is machined first, and then the annular groove nut 2 with the fuse hole 25 facing upwards is placed into the tooling groove 11 to facilitate the determination of the machining position of the oil groove hole 24.

[0024] The annular groove nut 2 has an internal threaded through hole 23 inside, and the oil groove hole 24 is connected to the internal threaded through hole 23.

[0025] When measuring whether the position of the oil groove hole 24 is correct, the annular groove nut 2 with the fuse hole 25 is placed upwards in the tooling groove 11, and the oil groove hole 24 and the guide hole 14 are visually checked to see if they correspond correctly. It can be seen that the tooling body 1 of this application can realize the drilling, positioning, machining and measurement of the oil groove hole 24.
