Embodiment Construction

[0023] The ear hole forming limit adjustment mechanism of the roll earphone is installed in the roll earphone, and its main function is to compress the sheet material for the ear rolling operation, so as to facilitate the ear rolling process.

[0024] In the same roll of earphones, in the process of ear rolling for different batches of sheet materials with different thicknesses, it is necessary to adjust the initial position and the pressing position of the ear hole forming limit adjustment mechanism in order to obtain a reasonable pressing force. At present, the use of oil cylinder is used for compression. In this simple compression mechanism, the piston in the oil cylinder is not at the bottom of the cylinder, and the force of compression is completely guaranteed by the pressure of hydraulic oil. Due to the hydraulic pressure and its compressibility , so that the pressing force fluctuates, which further affects the quality of the rolled ears.

[0025] Such as Figure 5 to F...

Abstract

The invention discloses a limiting and adjusting mechanism for forming lug holes of a lug winding machine. The limiting and adjusting mechanism comprises an oil cylinder, a connecting plate, a fixed seat, a guiding column and a pressing block, wherein the fixed seat is internally provided with a first axle hole and a second axle hole which are formed in parallel; a worm wheel is sheathed in the first axle hole, and a worm meshed with the worm wheel is arranged at one side of the fixed seat; the oil cylinder with outer threads on the outer surface is engaged at the axis of the worm wheel; the guiding column is sheathed in the second axle hole in a sliding-matching manner, and the lower end of a piston rod of the oil cylinder and the lower end of the guiding column are fixedly connected on the pressing block simultaneously; the connecting plate is arranged between the top part of a body of the oil cylinder and the guiding column; a screw locking structure is arranged between the oil cylinder and the fixed seat. The limiting and adjusting mechanism disclosed by the invention has the advantages that the process of pressing down a pressing plate is finished by the oil cylinder, a piston column reaches the bottom of the cylinder in the process of every processing, so that the position reliability is high.

Description

technical field [0001] The proposal belongs to the technical field of full-hydraulic earphone rolling machines, and specifically relates to an ear hole forming limit adjustment mechanism in earphone rolling. Background technique [0002] The ear rolling process in rolling earphones is as follows: Figure 1 to Figure 4 As shown, there are four steps of feeding, pressing, rolling, and loosening the workpiece. In the pressing process, the pressing plate 81 installed on the crankshaft is used to press the end of the leaf spring plate 82, and then the pressing plate is used to press Tightening plate 81 compresses and rotates so that the leaf spring sheet forms a roll ear 83 on the mould. In this process, it is necessary to use a limit mechanism 84 to fix the position of the sheet to assist. The current limit mechanism 84 uses an ordinary oil cylinder to limit the position, that is, directly uses an oil cylinder to compress the sheet for processing. , due to the different thickne...
