Mechanism for continuous drilling of workpieces

Abstract

The invention discloses a mechanism for continuously punching workpieces. The mechanism comprises a base (1) which is rotatably connected with a guide rod (3) through a rotating shaft (2), the guide rod (3) is slidably connected with a first linear rack (4) through a dovetail groove, and a drilling machine (6) used for punching a workpiece (5) placed on the base (1) is arranged on the first linear rack (4); a platform (7) is arranged on the base (1) and slidably connected with a slider (8) through the dovetail groove, and a connecting rod (9) is obliquely arranged on the slider (8). The mechanism is higher in punching accuracy and capable of guaranteeing included angles among multiple holes when the holes are processed at the same time.

Description

technical field [0001] The invention relates to the technical field of drilling, in particular to a mechanism for continuously drilling workpieces. Background technique [0002] Currently, drilling holes in workpieces is a routine machining operation. In the prior art, it is relatively easy to process a hole perpendicular to the surface of the workpiece. It is only necessary to face the drill bit to the surface of the workpiece and keep the drill bit perpendicular to the surface of the workpiece; The hole is relatively difficult, and it is difficult to ensure the machining accuracy. This is because in the process of processing inclined holes, it is necessary to maintain a certain inclination between the drill bit and the surface of the workpiece, and in the process of drilling, because the force received by the drill bit is not perpendicular to the drill bit Therefore, it is easy to cause uneven force on the drill bit, which will cause the drill bit to deviate when drilling...

Problems solved by technology

In the prior art, it is relatively easy to process a hole perpendicular to the surface of the workpiece. It is only necessary to face the drill bit to the surface of the workpiece and keep the drill bit perpendicular to the surface of the workpiece; The hole is relatively difficult, and it is difficult to ensure the machining accuracy. This is because in the process of processing inclined holes, it is necessary to maintain a certain inclination between the drill bit and the surface of the workpiece, and in the process of drilling, because the force received by the drill bit is not perpendicular to the drill bit Therefore, it is easy to cause uneven force on the drill bit, which will cause the drill bit to deviate when drilling inclined holes, which will cause the processed inclined holes to be unqualified; in addition, sometimes multiple holes are processed on the same workpiece, and multiple The angle between two holes, at this time, the structure of the swing drill angle and the stability requirements during the drilling process of the drill bit become higher again.

To sum up, in the prior art, the precision of the device for continuously punching the workpiece is not high enough, and the angle between the straight hole and the inclined hole cannot be guaranteed when processing the straight hole and the inclined hole at the same time.
