The invention belongs to the technical field of drilling machines, and discloses a drilling device of an anticollision steel beam. The drilling device comprises a workbench; a rectangular bracket is arranged on the workbench; a workpiece fixing mechanism is arranged in space defined by the bracket; a hydraulic oil cylinder and a motor are respectively arranged at the short edges of the bracket; the hydraulic oil cylinder is connected with a push rod; the motor is connected with a drilling rod; the drilling rod is connected with a drilling bit; the workpiece fixing mechanism comprises a fixing sleeve and U-shaped communicating vessels; two transverse side plates of the fixing sleeve are slidingly connected with baffles; the baffles are perpendicular to the transverse side plates of the fixing sleeve; the U-shaped communicating vessels are filled with oil; pistons and piston rods are arranged on two transverse pipes of each U-shaped communicating vessel; in each U-shaped communicating vessel, one end of one piston rod is connected with one piston and the other end thereof is connected with one transverse side plate of the fixing sleeve, and one end of the other one piston rod is connected with the other one piston and the other end thereof is connected with one baffle; and a reverse flow valve and an oil filling valve are arranged on each U-shaped communicating vessel. The problem that the machining precision is low in the prior art is solved.
Description
technical field [0001] The invention belongs to the field of drilling machinery, in particular to a drilling device for anti-collision steel beams. Background technique [0002] The anti-collision steel beam is a U-shaped groove stamped by cold-rolled steel plate, which is connected with the longitudinal beam of the frame. An important safety device is a very important part of a car. When the anti-collision steel beam is processed, holes need to be drilled to adapt to the installation on the car. The traditional drilling is done by manually holding the drilling machine. Due to the strong subjectivity of manual work, the precision of the drilling is not high, and it cannot be accurately installed on the car, resulting in a change in the safety performance of the car. Low; and the debris generated during drilling can easily cause workers to be injured. [0003] In order to solve the above problems, the Chinese patent with the patent publication number CN104759521B provides ...
