Problems solved by technology

When subjected to the pressure of the drill bit, the two metal plates will generate a moment, causing the first metal plate 21 or the second metal plate 22 to tilt, and the coaxiality of the first pin hole 21a and the second pin hole 21b cannot be guaranteed. In severe cases also damage the drill bit

Abstract

The invention discloses a drilling device for a U-shaped connector. The device comprises a worktable, a supporting system, a positioning block, a drilling bracket, a drilling device unit and a driving device, wherein the supporting system, the drilling bracket, the positioning block and the driving device are all mounted on the worktable; the drilling bracket is vertical to a working plane of the worktable; the drilling device unit, which can be mounted on the drilling bracket by sliding, is positioned at one side, close to the positioning block, of the drilling bracket; the supporting system comprises a supporting block, a rotating shaft, a hydraulic pump, a reversing valve and a hydraulic oil tank; the rotating shaft is connected to the worktable and is vertical to the working plane of the worktable; the supporting block is rotatably mounted on the rotating shaft; a hydraulic chamber in which a piston body is mounted is arranged on the supporting block; the reversing valve is provided with three end ports; a first end port communicates with the hydraulic chamber on the supporting block, a second end port communicates with the hydraulic oil tank, and a third end port is connected to a liquid outlet tube of the hydraulic pump; a liquid inlet tube of the hydraulic pump communicates with the hydraulic oil tank. The drive can improve the coaxiality of pin holes.

Description

technical field [0001] The invention relates to the technical field of metal processing, in particular to a U-shaped joint drilling device. Background technique [0002] In the process of connecting various transportation equipment, the U-shaped joint is a joint that is easy to install and has a better connection effect. [0003] like figure 1 as shown, figure 1 It is a U-shaped joint commonly used in the prior art, including a first connecting end 1 and a second connecting end 2. The first connecting end 1 is cylindrical and has a through hole along its axis; the second connecting end 2 is The first metal plate 21 and the second metal plate 22 are arranged in parallel, and the distance between them is greater than the diameter of the through hole on the first connection end 1 . The first metal plate 21 and the second metal plate 22 are respectively provided with a first pin hole 21a and a second pin hole 21b, and the two are coaxially arranged. [0004] During the proce...
