[0002] Plastic delivery reels are specialized reels used in the industry for the winding, unwinding, storage, and transportation of wires. They are widely used in fields such as enameled wire, stainless steel wire, bare copper wire, solder strip, optical fiber, cable, and wire harness. The market requires high dimensional accuracy for plastic delivery reels. After injection molding, the dimensional accuracy of the reels is difficult to meet the usage requirements, so they need to be machined to the appropriate size on a lathe.

[0003] Existing wire reels generally include two reels and a connecting shaft between the two reels; the connecting shaft has a drive hole, and the drive device of the lathe abuts against the drive hole. Through the cooperation of the ejector pin and the drive hole, the wire reel can be rotated and processed in the direction of rotation of the drive device.

[0004] When the existing automated lathe robot loads and unloads products, it achieves processing through the cooperation of a cylindrical ejector pin and a drive hole. However, it is necessary to fix and identify the angle of the plastic delivery reel, which affects the processing results and efficiency. Utility Model Content

[0005] This utility model provides a plastic delivery reel and a machining drive fixture, which can solve the problem in the prior art that when automating a lathe, it is necessary to fix and identify the angle of the plastic delivery reel, which affects the machining results and efficiency.

[0006] A plastic delivery reel includes a connecting shaft and a reel body disposed at both ends of the connecting shaft, wherein the connecting shaft has a first drive hole along its extension direction; A processing drive assembly is provided on the relatively distant side of the disc body; the processing drive assembly includes a drive protrusion; the drive protrusion is recessed inward to form a second drive hole, and the second drive hole contains at least one auxiliary rib arranged circumferentially along the direction of rotation of the plastic delivery line disc; at least one auxiliary rib divides the second drive hole into several drive cavities.

[0007] Preferably, the opposite sides of the discs at both ends of the connecting shaft are smooth, and a winding space is formed between the two discs and the connecting shaft.

[0008] Preferably, the driving protrusion is recessed inward to form a second driving hole, and the second driving hole is coaxially arranged with the first driving hole.

[0023] The specific embodiments of this utility model are described in detail below, but it should be understood that the scope of protection of this utility model is not limited to the specific embodiments.

[0024] Plastic wire reels are specialized reels used in the industry for the winding, storage, and transportation of wires. They are widely used in fields such as enameled wire, stainless steel wire, bare copper wire, solder strip, optical fiber, cables, and wire harnesses. Based on their shape, they are generally classified into conical wire reels, flat cylindrical wire reels, flat double-conical wire reels, and cylindrical wire reels. Based on the type of wire, they can also be classified into wire reels for enameled flat wire, wire reels for automotive wire harnesses, and wire reels for optical fiber cables. Plastic delivery reels are generally made of nylon + 30% glass fiber material. They are formed by injecting molten plastic into a mold and allowing it to cool. The market requires high dimensional accuracy for plastic delivery reels. After injection molding, the dimensional accuracy of the reels is difficult to meet the usage requirements, so they need to be machined to the appropriate size on a lathe.

[0025] like Figure 1 As shown, existing wire reels generally include two reels 1 and a connecting shaft 2 disposed between the two reels 1; the connecting shaft 2 has a drive hole, and the center of the lathe's drive device abuts against the drive hole. Through the cooperation between the center and the drive hole, the wire reel can be rotated and processed in the direction of rotation of the drive device.

[0026] When the existing robotic arms in the automation of lathes load and unload products, the lathe center is specifically a cylindrical structure with a tapered end. The machining is achieved through the cooperation between the cylindrical center and the drive hole. It is also necessary to fix and identify the angle of the plastic delivery reel, which affects the machining results and efficiency.

[0027] To address the issue of needing to fix and identify the angle of plastic delivery coils during coil lathe processing, which affects processing efficiency, this invention improves the coil structure and ejector pin structure. The improved construction of the coil drive hole and ejector pin structure aims to prevent relative sliding between the coil and ejector pin during processing.

[0028] Based on the above objectives, one embodiment of the present invention provides a plastic delivery reel; specifically, please refer to... Figures 2-3 The plastic delivery reel proposed in this embodiment includes a connecting shaft 2 and a reel body 1 disposed at both ends of the connecting shaft 2; the reel body 1 and the connecting shaft 2 are integrally injection molded; the connecting shaft 2 is provided with a first driving hole 4 along the extension direction of the connecting shaft 2; the first driving hole 4 is configured as a component that cooperates with an ejector pin, so as to drive the plastic delivery reel to rotate for processing by rotating the ejector pin.

[0029] The opposite sides of the discs 1 at both ends of the connecting shaft 2 are smooth, and a winding space is formed between the two discs 1 and the connecting shaft 2 for winding wires similar to fine metal wires, so as to complete the winding, storage and transportation of the wires.

[0030] Among them, a processing drive assembly 3 is provided on the relatively far sides of the two disks 1; the processing drive assembly 3 includes a drive protrusion; the drive protrusion is recessed inward to form a second drive hole 5, and the second drive hole 5 is coaxially arranged with the first drive hole 4. Furthermore, the second drive hole 5 has at least one auxiliary rib 31 built in; the auxiliary rib 31 is circumferentially arranged along the direction of rotation of the plastic delivery coil; the second drive hole 5 is divided into several drive cavities by at least one auxiliary rib 31; It should be noted that the auxiliary rib 31 extends along the edge of the second drive hole 5 toward the center of the second drive hole 5 and intersects and ends at the first drive hole 4.

[0031] The second drive hole 5 penetrates the drive protrusion, but its depth is less than the thickness of the drive protrusion and the single disc body 1. The connecting shaft 2, the disc body 1, and the machining drive assembly 3 are all integrally injection molded.

[0032] According to the requirements of the machining drive fixture, the number of auxiliary ribs 31 can be set to one, that is, the second drive hole 5 is divided into two drive cavities. Correspondingly, the machining drive fixture needs to be set accordingly; for example, the number of auxiliary ribs 31 can be three or four; dividing the second drive hole 5 into several drive cavities. As an alternative implementation, taking eight auxiliary ribs 31 as an example, please refer to... Figure 3 As shown in the figure, there are eight auxiliary ribs 31. The auxiliary ribs 31 divide the second driving hole 5 into eight driving cavities. Two of the auxiliary ribs 31 are arranged in parallel, and the remaining auxiliary ribs 31 extend along the edge of the second driving hole 5 toward the center of the second driving hole 5 and intersect with the first driving hole 4 and stop. The second driving hole 5 is divided into two square driving cavities, four triangular driving cavities, and two fan-shaped driving cavities. To facilitate post-injection molding processing of plastic delivery reels, such as Figure 4-6The present invention also proposes a machining drive fixture, which includes a drive fixture 61 and a machining pin 62. The machining pin 62 is disposed at the end of the drive fixture 61 and is used to cooperate with the first drive hole 4. A plurality of sliding pins 63 are provided circumferentially at the end of the drive clamp 61; Specifically, the interior of the drive clamp 61 is provided with a plurality of mating slots according to the number of sliding ejector pins 63. The mating slots are recessed from the end of the drive clamp 61 connected to the ejector pin to the end away from the ejector pin, and do not penetrate the bottom surface. The sliding pin 63 is fitted inside the mating slot, and all sliding pins 63 extend out of the mating slot. The sliding pin 63 can slide inside the mating slot. The part of the sliding pin 63 located inside the mating slot is connected to a slip spring 64. One end of the slip spring 64 is fixed to the end of the sliding pin 63, and the other end is fixedly connected to the inner bottom surface of the mating slot. The sliding pin 63 can extend and retract inside the mating slot by the setting of the slip spring 64. When the slip spring 64 is in the free state, the end of the sliding pin 63 protrudes out of the mating slot.

[0033] As an optional implementation, when the sliding ejector pin 63 abuts against the auxiliary rib 31 during processing, once the plastic delivery reel slides against the processing ejector pin 62, the sliding ejector pin 63 will slide from the auxiliary rib 31 into the drive cavity. The slip spring 64 will push the sliding ejector pin 63 out, and the plastic delivery reel will be relatively fixed to the machining drive fixture, preventing tool collision, improving processing efficiency, and avoiding the need to fix and identify the angle of the plastic delivery reel when the existing automated lathe robot is loading and unloading products, which affects the processing results and efficiency.

[0034] The principle of this embodiment is as follows: A plastic delivery reel is integrally injection molded, comprising a connecting shaft 2, a disc body 1 disposed at both ends of the connecting shaft 2, and a processing drive assembly 3 disposed on the relatively distant side of the disc body 1. The plastic delivery reel is then machined, and the processing pins 62 of the two machining drive fixtures are moved into the first drive hole 4 of the plastic delivery reel and cooperate with the first drive hole 4. At this time, the sliding ejector pin 63 has two states: the sliding ejector pin 63 abuts against the auxiliary rib 31 or the sliding ejector pin 63 extends into the interior of the drive cavity. When the sliding ejector pin 63 extends into the interior of the drive cavity, and the drive fixture 61 rotates, the sliding ejector pin 63 abuts against the inner wall of the auxiliary rib 31 of the drive cavity. During the processing, the plastic delivery coil and the machining drive fixture are relatively fixed, which will not cause tool collision. When the sliding ejector pin 63 abuts against the auxiliary rib 31, and the plastic delivery reel slides against the machining ejector pin 62, the sliding ejector pin 63 will slide from the auxiliary rib 31 into the drive cavity. The slip spring 64 will push the sliding ejector pin 63 out, and the plastic delivery reel will be relatively fixed to the machining drive fixture, preventing tool collision.

[0035] The above-disclosed embodiments are only a few specific examples of the present utility model. However, the embodiments of the present utility model are not limited thereto. Any changes that can be conceived by those skilled in the art should fall within the protection scope of the present utility model.
