Pressure type gang drill self-locking mechanism

Abstract

The invention discloses a pressure type gang drill self-locking mechanism which comprises a fixing rack and a vertical air cylinder arranged on the fixing rack. The vertical air cylinder comprises a first air cylinder body, a first piston, a first air cylinder shaft, a first reset spring and a first fixing base, wherein the periphery of the first air cylinder body is provided with a lateral movement assembly, the lateral movement assembly is provided with an annular sleeve and a lateral movement slide block, and an annular oblique plane opening outwards is formed in the upper side edge of theinner side face, away from the lateral movement slide block, of the annular sleeve. A side locking spring is arranged between the outer end of the lateral movement slide block and the first fixing base. The outer side face of the upper end of the first air cylinder shaft is provided with a clamping groove and a positioning clamp point, and the lower end edge of the clamping groove outwards protrudes to form a clamping tenon. The fixing rack is provided with an unlocking drive mechanism. When the pressure type gang drill self-locking mechanism executes machining operation, the air cylinder shaft can be locked and gas stop machining can be executed only by executing gas introduction for the vertical air cylinder for 1.5 minutes, and the machining demand, which can be met by an existing mechanism through continuous gas feeding during machining, is met.

Description

technical field [0001] The invention belongs to the technical field of drill row equipment, and in particular relates to a pneumatic drill row self-locking mechanism. Background technique [0002] At present, in the furniture manufacturing industry, the connection of panel furniture and the installation of hardware accessories mostly require drilling holes on the surface of the panels. The drilling equipment is generally a woodworking machine or a drilling machine with a pneumatic drill. However, the existing pneumatic drill row structure has no self-locking function, and only the cylinder drives the rotating shaft that needs to work to descend, and after descending, the returning spring realizes the rising and reset of the rotating shaft. This pneumatic drilling structure needs to supply air to the cylinder all the time after the rotating shaft is lowered so that the rotating shaft is in the working position. The tool retracts, thereby affecting the processing depth of the...

AI Technical Summary

Problems solved by technology

This pneumatic drilling structure needs to supply air to the cylinder all the time after the rotating shaft is lowered so that the rotating shaft is in the working position. The tool retracts, which affects the processing depth of the drill bit to the hole position, and it is difficult to ensure the quality and consistency of the drilling depth
