[0035] The following is a further detailed description of this application.

[0036] This application discloses a coaxial roller device for radio frequency connectors. (Refer to...) Figure 1 The RF connector coaxial rolling device includes: a machine base 10, an imprinting rotating shaft assembly 20, and a fixing assembly 30. The imprinting rotating shaft assembly 20 and the fixing assembly 30 are arranged opposite each other on both sides of the machine base 10. The imprinting rotating shaft assembly 20 rotates relative to the fixing assembly 30. One end of the fixing assembly 30 is used to fit into the workpiece to be processed for assembling the RF connector coaxial. By rotating the imprinting rotating shaft assembly 20, the surface of the workpiece to be processed is rolled. Of course, in another embodiment, the workpiece to be processed is not limited to the assembly parts of the RF connector coaxial, but can also be other components that need to be rolled.

[0037] The machine base 10 can be a rectangular flat table surface, with a first through-hole 11 and a second through-hole 12 arranged opposite to each other on the table surface; the printing rotary shaft assembly 20 includes a bearing end 21 and a first rotating end 22 located at opposite ends, a rolling element 23 arranged laterally on the first rotating end 22 and having a character mold cutting edge on its outer edge, and a driving element arranged on the first rotating end 22, wherein the bearing end 21 rotates the printing rotary shaft assembly 20 on the machine base 10 through the first through-hole 11, which can facilitate the rolling operation of the operator and improve the rolling efficiency; the fixing assembly 30 includes a support end 31 located at opposite ends and a fixing end 32 for the workpiece to be processed to be fitted in, wherein the fixing end 32 passes through the second through-hole 11. 2. Fixing the fixing component 30 on the machine base 10, with the support end 31 perpendicularly corresponding to the roller piece 23, ensures that the depth of the roller indentation is consistent, resulting in uniform lettering depth and thus guaranteeing the quality of the roller. In addition, the driving component can be a wrench that is easy to hold and detachably fitted onto the first rotating end 22, so that the operator can manually apply force to drive the overall rotation of the printing rotating shaft assembly 20, thereby realizing the roller operation of the letter mold cutting edge of the roller piece 23. Of course, the driving method is not limited here, as long as it can achieve the same function. For example, in other embodiments, the driving component can be a drive motor, which drives the rotation of the first rotating end 22 through motor drive, thereby realizing the overall rotation of the printing rotating shaft assembly 20.

The adjustment platform 41 is provided with an adjustment hole 411 for adjustment and a third through-hole 412 corresponding to the second through-hole 12. The support end 31 protrudes from the third through-hole 412. A fixing hole 13 is provided on the machine base 10 corresponding to the adjustment hole 411. Here, multiple fixing holes 13 are provided on the adjustment platform 41 and the machine base 10. The adjustment hole 41 and the fixing hole 13 can be connected by a screw through the adjustment hole 411 and the fixing hole 13 in sequence and fixed by a nut. This allows the operator to move the adjustment platform 41 based on the position of the roller piece 23 of the printing rotating shaft assembly 20 on the machine base 10, that is, to move the fixing component 30, so as to adjust the roller distance between the roller piece 23 and the workpiece to be processed sleeved on the support 32. The adjustment platform 41 is fixed to the fixing hole 13 on the machine base 10 through the adjustment hole 411, which can ensure that the machine base 10 maintains the stability of the overall structure during the roller process.

[0040] In addition, such as Figure 2 As shown, one end of the adjustment platform 41 is also provided with a first positioning slot 413 that passes through the third through-hole 412, which can be used to position the adjustment platform 41 with reference to the fixing hole 13 when the position is moved, so as to facilitate assembly and fixation.

The push block 44 can increase the surface area of ​​the pushing force so that the adjustment table 41 can move at a uniform speed. In another embodiment, the push block 44 can be integrally set with the adjustment table so that the adjustment table 41 can move with the push and pull of the push and pull rod 43.

[0043] Specifically, such as Figure 1 As shown, the second rotating end 431 and the pushing end 432 are connected by a threaded connecting rod 433. The push-pull hole 421 is provided with an internal thread corresponding to the threaded connecting rod 433. The external thread of the push-pull rod 43 rotates in conjunction with the internal thread of the push-pull hole 421, so as to realize the rotation of the second rotating end 431 to drive the pushing end 432 to push and pull the pushing block 44 to move, thereby realizing the movement and adjustment of the adjustment table 41.

[0044] See Figure 4 The first rotating end 22 includes a rotating shaft 221, a support member 222, a cover member 223, and a first fixing member 224. The tube-shaped member 23 is fitted between the cover member 223 and the support member 222. The tube-shaped member 23 and the support member 222 are sequentially sleeved on the rotating shaft 221. The rotating shaft 221 is connected by the first fixing member 224 through the cover member 223 to achieve integrated fixing. Here, integrated fixing can be understood as the rotating shaft 221, the cover member 223, the tube-shaped member 23, and the support member 222 being fixed together and rotating synchronously.

[0045] The rotating shaft 221 has a first fixing slot 2211 at its upper end for connection to the first fixing member 224, and a locking protrusion 2212 on its side for engagement and positioning. The first fixing slot 2211 can be a threaded hole that mates with the first fixing member 224. The support member 222 is fitted onto the rotating shaft 221 by engaging the locking protrusion 2212. The support member 222 has a notch 2221 on its edge. The truncated tube 23 includes a receiving end 231 at opposite ends and a truncated tube end 232 with raised lettering. The receiving end 231 is received in the support member 222. In the middle, the roll end 232 is connected to the receiving end 231 protruding from the notch 2221 for rolling; the receiving end 231 is provided with a first through hole 2311 corresponding to the first fixing slot 2211 to fit the rotating shaft 221; the cover 223 covers the receiving end 231 of the roll part 23 in the support 222, and the cover 223 is provided with a second through hole so that the first fixing member 224 can be fixed in the first fixing slot 2211 through the second through hole; the first fixing member 224 can be a threaded rod to be fixedly connected in the threaded hole of the first fixing slot 2211. In addition, a second engaging groove 2312 is provided at the receiving end 231 of the roll member 23 for engaging the engaging protrusion 2212, so as to position and engage the roll member 23 when it is sleeved on the rotating shaft 221 and increase the stability of the roll member 23, thereby improving the roll quality of the roll member 23.

[0046] Further, see Figure 3 and Figure 4 The fixed end 32 includes a threaded connector 321 that connects to the support end 31. The threaded connector 321 includes a screwing end 3211 and a threaded connection end 3212 located at opposite ends. The end of the support end 31 that connects to the fixed end 32 is provided with a threaded connection slot for the threaded connection end 3212 to connect. The screwing end 3211 is exposed from the second through-hole 12 and the third through-hole 412, which facilitates the disassembly of the fixed end 32 that connects to the support end 31, so that the support end 31 can be replaced according to the requirements, i.e., the size of the workpiece to be processed.

[0047] Further, see Figure 3 and Figure 4 The bearing end 21 includes a bearing 211 disposed in the first through-hole 11 and a shaft connector 212 that passes through the bearing 211 and connects to the shaft 221. It can be used to make the printing rotating shaft assembly 20 rotate synchronously with the drive component to realize the operation of rotating the roller end. The shaft connector 212 facilitates the disassembly and assembly of the printing rotating shaft assembly 20.

[0048] See Figure 3The coaxial roller device for the RF connector also includes a fixed platform 45 disposed on the machine base 10 away from the first rotating end 22, and a fourth through port 451 is provided on the fixed platform 45 corresponding to the first through port 11.

[0049] The fixed platform 45 is provided with a second positioning slot 452 through the fourth through-hole 451 at one end, which can be used to position the fixed hole 13 for easy assembly and fixing.

[0050] Additionally, see Figure 1 The coaxial roller assembly for the RF connector also includes a support leg 50 for the machine base 10, providing the machine base 10 with a support height, wherein the height of the support leg 50 must be greater than the thickness of the fixed platform 45.

[0051] For example, the working principle of the coaxial roller device for RF connectors is as follows:

[0052] The operator places the workpiece to be processed onto the support 222 and applies rotational force by using a drive component, such as a wrench, placed on the first fixed component 224, to drive the printing rotating shaft assembly 20 to rotate as a whole. This causes the lettering edge on the outer edge of the rolling piece 23 to be tangent to the outer surface of the workpiece. As the rolling piece 23 continues to rotate, the workpiece to be processed also rotates on the support 222 under the drive of the rolling piece 23. During the rotation, the lettering edge of the rolling piece 23 presses an indented mark corresponding to the lettering onto the outer surface of the workpiece, thereby realizing the rolling operation.

[0053] In summary, the coaxial roller forming device for RF connectors provided in this application embodiment, by setting an imprinting rotating shaft assembly 20 and a fixing assembly 30 on the machine base 10, with a roller forming component 23 having a character-shaped cutting edge on the imprinting rotating shaft assembly 20, and a support component 222 for fitting the workpiece to be processed on the fixing assembly 30, and the roller forming component 23 being arranged perpendicularly to the support component 222, can quickly realize the roller forming operation on the workpiece by driving the roller forming component 23 with the character-shaped cutting edge to be tangent to the outer surface of the workpiece as the first rotating end 22 rotates, and driving the workpiece to be processed to rotate on the support component 222. This roller forming operation can improve the uniformity of the roller forming on the surface of the workpiece, the roller forming efficiency, and the roller forming quality; by setting a position adjustment assembly 40 on the machine base 10, the position adjustment assembly 40 including an adjustment table 41, adjusting... An adjustment hole 411 is provided on the stage 41, and a fixing hole 13 is provided on the machine base 10 corresponding to the adjustment hole 411. This allows the stage 41 to be moved and fixed on the machine base 10 based on the roller piece 23 of the printing rotary shaft assembly 20. This allows the customer's requirements for the roller depth to be met based on the roller distance between the roller piece 23 and the workpiece to be processed, and ensures the structural stability after adjusting the distance. A baffle 42 and a push-pull rod 43 that abuts against the stage 41 are provided on the side of the machine base 10 away from the printing rotary shaft assembly 20. A push-pull hole 421 that guides the push-pull rod 43 is provided on the baffle 42.
