Description

Technical Field

[0001] This utility model relates to the technical field of radio frequency connector flange production equipment, and more specifically to a flange drilling device for radio frequency connector production. Background Technology

[0002] RF coaxial connectors are medium-power connectors with threaded connections, commonly used in the communications field to connect equipment and RF coaxial cables. They are characterized by high reliability, strong shock resistance, and excellent mechanical and electrical performance. A flange seat is required for connection, and holes need to be drilled in the flange seat for subsequent assembly.

[0003] According to utility model patent application CN210040795U, published on February 7, 2020, a highly stable RF connector flange seat is disclosed. It includes a base portion with a central through hole and internal threads; a mating sleeve portion disposed on the base portion and communicating with the central through hole, wherein a core of an inner conductor is mounted and fixed in the mating sleeve portion; and an elongating flange extending taperedly from the mating sleeve portion, the diameter of the elongating flange being smaller than the diameter of the mating sleeve portion; wherein an annular band is formed around the inner wall of the mating sleeve portion, and an annular groove is formed between the annular band and the elongating flange, the diameter of the annular band being larger than the diameter of the elongating flange. Its main technical effect is that by cooperating with the elongating flange, the annular band and the annular groove jointly limit and stabilize the core, avoiding the problem of core loosening that easily occurs with direct fitting in the past.

[0004] Since the flanges of RF connectors are typically small in size and the drilling of the flanges is usually at the edge, existing conventional external clamping fixtures are difficult to adapt to. Therefore, a flange drilling device for RF connector production is proposed, which aims to solve the problem that conventional external clamping fixtures in the prior art are difficult to adapt to the production of small-sized RF connector flanges.

[0022] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0023] Please see Figures 1-5 A flange drilling device for producing radio frequency connectors includes a drilling machine body 1 and a clamping mechanism 2 disposed on the drilling machine body 1. The clamping mechanism 2 includes an inner chuck 21 and a support platform 22. The inner chuck 21 is slidably disposed on the drilling machine body 1, and the support platform 22 is slidably connected to the inner chuck 21. The device clamps the workpiece by driving the inner chuck 21 to move outward, and supports the edge of the workpiece by the support platform 22.

[0024] It should be noted that the drill body 1 is a conventional drill in the prior art, and its working principle will not be described in detail here.

[0025] The clamping mechanism 2 is mounted on the worktable of the drilling machine body 1, and the position of the worktable can be adjusted to achieve different positions on the flange seat. It should be noted that the clamping mechanism 2 can be stably fixed by its own weight by being placed directly on the drilling machine body 1, or it can be rotatably connected to the drilling machine body 1 via a rotating shaft to achieve rotary drilling of the flange. Alternatively, the drilling machine body 1 can be replaced with a three-axis machining center, and the clamping mechanism 2 can be fixedly mounted on the operating table of the machining center to achieve drilling of the flange.

[0026] As an embodiment provided by this utility model, such as Figure 2 , Figure 3 and Figure 4As shown, the clamping mechanism 2 includes an inner chuck 21 and a support table 22. The inner chuck 21 can slide on the drill press body 1, and the support table 22 is slidably connected to the inner chuck 21. By driving the inner chuck 21 to move outward and abutting against the inner wall of the flange circumference, the flange is fixed. Simultaneously, the support table 22 supports the edge of the flange to prevent deformation during machining. When machining a flange with a square base, machining can be achieved by adjusting the position of the support table 22. When machining a flange with a round base, it can be machined directly.

[0027] This utility model, by driving the inner chuck 21 to move outward and abut against the inner wall of the flange, can ensure that the flange is clamped. At the same time, because it abuts against the inner wall of the flange, it can be applied not only to the production of smaller flanges but also to the production of larger flanges. During the flange drilling production, the position of the support platform 22 on the inner chuck 21 can be adjusted to support the edge of the flange and ensure the stability during processing. The clamping mechanism 2 cooperates with the drilling machine body 1 to perform drilling, so as to adapt to the production of products of different sizes.

[0028] As a further embodiment provided by this utility model, such as Figure 4 and Figure 5 As shown, the clamping mechanism 2 also includes a housing 23, a drive rod 24, and a drive disk 25. The housing 23 is mounted on the outer wall of one side of the drill body 1. The housing 23 is specifically a hollow structure. The drive disk 25 is rotatably connected to the inside of the housing 23, and the drive rod 24 is rotatably connected to the housing 23. As an embodiment provided by this utility model, a bevel gear is provided at one end of the drive rod 24 located inside the housing 23. The outer wall of one side of the drive disk 25 has a toothed structure, and the bevel gear meshes with the toothed structure. By rotating the drive rod 24, the drive disk 25 can be driven to rotate. On the other side of the drive disk 25... The outer surface is provided with a spiral tooth structure, and the bottom of the inner chuck 21 is provided with a toothed structure that can mesh with the spiral tooth structure. A sliding groove is provided on the outer shell 23, and the inner chuck 21 is slidably connected to the outer shell 23 through the sliding groove on the outer shell 23. That is, the inner chuck 21 is connected to the drilling machine body 1 through the outer shell 23. When the drive rod 24 keeps rotating, it can synchronously drive the drive disk 25 to keep rotating. The rotation of the drive disk 25 drives the inner chuck 21 to keep reciprocating in the sliding groove of the outer shell 23, thereby clamping the workpiece to be processed through the inner chuck 21. As a preferred embodiment of the present invention, the number of inner chucks 21 is at least three, and they are arranged in a circumferential array on the outer shell 23.

[0029] As a further embodiment provided by this utility model, such as Figure 3As shown, an abutment clamping rod 26 is fixedly installed on the inner clamp 21. An arc-shaped abutment block 27 is provided on the periphery of the abutment clamping rod 26. The arc-shaped abutment block 27 can support the bottom edge of the flange and limit the flange, so that the flange can be placed on the abutment clamping rod 26.

[0030] Furthermore, such as Figure 2 As shown, a groove is provided on the outer wall of the inner clamp 21. The support platform 22 is slidably connected to the inner clamp 21 through the groove. The position of the support platform 22 on the inner clamp 21 can be adjusted to support the edge of flanges of different sizes, facilitating drilling and preventing deformation of the flange edge during drilling. It should be noted that the groove is a dovetail groove to prevent the support platform 22 from falling off.

[0031] As a further embodiment provided by this utility model, such as Figure 3 As shown, a positioning plate 28 is fixedly installed on the outer wall of one end of the inner clamp 21. A push rod 29 is threadedly connected to the positioning plate 28. One end of the push rod 29 passes through and extends to the other side of the positioning plate 28. The end of the push rod 29 located in the slide groove is connected to the support platform 22.

[0032] A compression spring can be installed between the inner wall of the slide groove on the inner clamp 21 and the support platform 22. At this time, the push rod 29 and the support platform 22 can be connected by abutment. By rotating the push rod 29, the support platform 22 can be pushed to the position in the slide groove.

[0033] The support platform 22 and the push rod 29 can also be rotatably connected. In this case, there is no need to compress the spring, and the movement of the support platform 22 in the slide can be adjusted by rotating the push rod 29.

[0034] It should be noted that in this embodiment, the end of the inner clamp 21 away from the positioning plate 28 can be a planar structure, which can realize the external clamping of the workpiece and is more practical.

[0035] The compression spring mentioned in this article has an elastic coefficient that meets the technical requirements of this utility model.

[0036] Those skilled in the art will understand that other similar connection methods can also achieve this utility model. For example, welding, bonding, or screwing.

[0037] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
