Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of fishing gear manufacturing equipment, specifically a multi-station screw-locking and line-attaching device for the main cover of a fishing reel. Background Technology
[0002] In the fishing tackle manufacturing industry, it is often necessary to assemble the main cover of the fishing reel. The traditional assembly method usually relies on manual screw tightening of screws to assemble the main cover of the fishing reel. With the increase in market demand, the traditional manual screw tightening is difficult to adapt to the high-speed production requirements.
[0003] Currently, a new device has emerged in the manufacturing industry to replace manual labor in screwing the main caps of fishing reels. This device uses multiple sets of main cap fixtures evenly fixed on a reel disc. A servo motor controls the reel disc to rotate at a predetermined angle. Above the fixture's resting position, a hydraulic rod pushes a clamping plate to press down and clamp the main cap of the fishing reel placed in the fixture. A robotic arm then automatically screws the main cap onto the fishing reel. The reel disc has multiple corresponding workstations, allowing for screwing different parts of the main cap. This multi-workstation setup significantly accelerates production speed. Furthermore, at the workstation following the last screw-locking station, the robotic arm removes the screw-locked fishing reel from the fixture and places it on a conveyor belt for subsequent processes. This device greatly increases production efficiency and saves labor costs.
[0004] However, in existing fishing reel main cover multi-station screw-locking line-attaching devices, the fixture is usually fixed to the reel disc with screws. However, during processing, prolonged mechanical vibration may cause the screws to loosen, causing the fixture to come loose. To increase the firmness, the number of screws needs to be increased. However, when it is necessary to process other types of fishing reels and change the fixture, disassembly and assembly are very inconvenient. There is a lack of a corresponding multi-station screw-locking line-attaching device for the fishing reel main cover that allows for convenient and quick fixture replacement and secure installation, which needs to be improved and optimized. Utility Model Content

[0006] To achieve the above objectives, this utility model provides the following technical solution: A multi-station screw-locking and line-raising device for the main cover of a fishing reel includes a screw-locking and line-raising device body. One end of the screw-locking and line-raising device body is connected to a turntable. One end of the turntable is provided with a limiting installation groove. A fixture is fixedly inserted into the limiting installation groove. One end of the fixture is fixedly connected to a pin assembly. A fixing slot is provided in the middle of the limiting installation groove. A pin assembly is inserted into the fixing slot. Pin grooves are symmetrically provided at both ends of the fixing slot. Locking pin assemblies are provided in the pin grooves.
[0007] Preferably, the pin assembly includes a pin that is inserted into a fixed slot, with locking holes symmetrically provided at both ends of the pin, auxiliary insertion holes symmetrically provided at both ends of the pin, and a groove provided at one end of the pin.
[0008] Preferably, a pin is inserted into the middle of the column groove, and a second magnet is fixedly connected to both ends of the middle of the pin. A second spring is fixedly connected to one end of the pin, and the other end of the second spring is fixedly connected to the inner wall of the column groove.
[0009] Preferably, the locking pin assembly includes a locking pin, which is inserted into a pin groove, one end of which is inserted into a locking hole, and the other end of which is fixedly connected to a first spring, one end of which is fixedly connected to the inner wall of the pin groove.
