Description

Technical Field

[0001] This utility model relates to the technical field of insert pin processing equipment, and specifically to a tooling for processing the outer diameter of insert pins. Background Technology

[0002] Ceramic ferrule pins, also known as fiber optic connector ceramic ferrule pins, are precision tools used in the injection molding production of nano-zirconia ceramic ferrules. They are core mold components in the field of optical communication equipment manufacturing. Their core function is to achieve high-precision molding of fiber optic connector ferrules, ensuring the accuracy of fiber optic connection, and are used in the manufacturing of basic structures for optical communication systems.

[0003] Existing ceramic ferrule pin structures vary considerably, and the clamping methods differ depending on the product structure. When the product has a large flat surface (disc-shaped, ring-shaped, plate-shaped, block-shaped), a high-temperature wax-melting process can be used, where wax is applied to the flat surface and bonded to the fixture plate. After cooling, it has sufficient stability and firmness. When the product has a large unprocessed area, a bolt-locking pressure plate is used, where the pressure plate presses down on the unprocessed area to reduce wax adhesion and dewaxing time. However, for round ferrule pins, due to their small end face areas and relatively long and slender overall dimensions, the high-temperature wax-melting method for bonding to the fixture plate results in insufficient end face adhesion. This can easily lead to problems such as tool flying out or breaking the round ferrule pin during processing, resulting in a significant decrease in yield. Utility Model Content

[0009] As a further description of the above technical solution, the fixing cavity includes a first locking cavity and a second locking cavity, and the lock cylinder is inserted into the first locking cavity.

[0011] As a further description of the above technical solution, the molten core is inserted into the cavity formed by the lock cylinder and the second locking cavity.

[0012] As a further description of the above technical solution, the end of the insert pin abuts against the rear cover.

[0029] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings.

[0030] like Figures 1-6 As shown, in one embodiment, a tooling for machining the outer diameter of a core insert includes: a clamping block 1 and a back cover 2.

[0031] The clamping block 1 and the rear cover 2 are cylindrical, which facilitates clamping and positioning on CNC grinding machines and other processing equipment. The clamping block 1 is equipped with a locking core 3, which is used to apply a uniform clamping force to the insert pin 4, thereby achieving the clamping and fixing of the insert pin 4. The rear cover 2 is detachably connected to the clamping block 1 through a connector (such as screws or bolts), which is used to abut and limit the insert pin 4, ensuring that the insert pin 4 will not have axial displacement during processing.

[0032] For example, the clamping block 1 has multiple sets of first fixing cavities 11 inside, and the lock cylinder 3 is inserted into one of the first fixing cavities 11.

[0033] It should be explained in detail that the fixing cavity includes a first locking cavity 111 and a second locking cavity 112 that penetrate the clamping block 1, and the axes of the first locking cavity 111 and the second locking cavity 112 overlap. Specifically, the first locking cavity 111 and the second locking cavity 112 are fan-shaped, and the diameter of the first locking cavity 111 is larger than the diameter of the second locking cavity 112.

[0034] Correspondingly, the lock cylinder 3 is inserted into the first locking cavity 111, while the molten core 4 is inserted into the placement cavity formed by the lock cylinder 3 and the second locking cavity 112, so that the molten core 4 is in a relatively closed and fitted cavity, and the molten core 4 is limited in the radial direction.

[0035] Furthermore, a first threaded hole 12 is provided on the side of the clamping block 1, and the first threaded hole 12 communicates with the first locking cavity 111. Specifically, a first locking member 13 (such as a screw or bolt) is installed in the first threaded hole 12, so that the bottom of the first locking member 13 can abut against the lock cylinder 3 after being tightened; when the first locking member 13 is gradually tightened, its bottom will slowly abut against the lock cylinder 3. As the tightening force increases, the lock cylinder 3 will be continuously pressed down, thus tightly fitting against the insert pin 4, thereby locking and fixing the insert pin 4 and preventing loosening during processing.

[0036] Correspondingly, the clamping block 1 has symmetrical second threaded holes 14 at both ends, which are used to install the second locking element 15 (such as screws or bolts); while the rear cover 2 has symmetrical third threaded holes 22 at both ends, which are used to install the second locking element 15. This allows the third threaded hole 22 on the rear cover 2 to be fitted and fixed to the second threaded hole 14 on the clamping block 1 through the second locking element 15, thereby adjusting the insertion depth of the round insert pin 4.

[0037] In addition, a clearance groove 21 is provided on one side of the back cover 2, and the diameter of the clearance groove 21 is larger than the diameter of the lock cylinder 3, so that the end of the molten core 4 can abut against the back cover 2, thereby providing a reliable axial support for the molten core 4, effectively preventing the molten core 4 from shaking due to lack of restraint during processing, and further ensuring the stability of processing.

[0038] Working principle: The clamping block 1 and the rear cover 2 are connected by a locking device. The clamping block 1 has fixed cavities of different diameters inside. After the fan-shaped lock core 3 is inserted, it surrounds and forms a placement cavity. The end of the inserted core pin 4 abuts against the clearance groove 21 of the rear cover 2. The middle part of the core pin 4 is abutted and fixed by the locking device installed on the top of the clamping block 1. Finally, the clamping block 1 is clamped on the machining station of the CNC grinding machine for processing.

[0039] Through the above technical solution, this application can firmly clamp the slender insert pin 4, so that the insert pin 4 can maintain a stable posture during processing, effectively reducing processing errors caused by shaking and improving the yield.

[0040] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
