Leftward/rightward rotating punching machine

Abstract

The invention relates to a leftward / rightward rotating punching machine, comprising an upper body, a supporting part and a lower body, wherein the supporting part is connected between the upper body and the lower body. The punching machine is characterized in that the upper body comprises an upper housing, a punching part, a wrench and a power mechanism 1; the punching part comprises a spindle 21, a chuck and a drill; the chuck is positioned at the front end of the spindle 21 and is used for fixing the drill; the wrench is connected with the punching part and is used for pushing the punching part; the power mechanism 1 is connected with the punching part and is used for providing power for rotation of the punching part; the lower body comprises a stage, a spindle 22 and a power mechanism 2, wherein the stage comprises a clamping device; the clamping device is positioned on the stage and is used for clamping the workpiece; the spindle 22 is connected with the clamping device on the stage; the power mechanism 2 is connected with the spindle 22; when the punching machine punches holes, the punching part rotates; and meanwhile, the spindle 22 drives the clamping device to further drive the workpiece to rotate oppositely relative to the punching part.

Description

technical field [0001] The invention relates to a punching machine, in particular to a punching machine which can rotate left and right. Background technique [0002] In recent years, with the rapid development of manufacturing industries such as automobiles and ships and the chemical industry, the scope of use of punching machines has become wider. Therefore, how to drill holes quickly and accurately on the basis of reducing labor intensity has become an a big problem. Domestic counterparts have invested manpower and material resources in the development of the above-mentioned problems, but they are not very satisfactory. The reason is mainly that holes of 1-2 mm are punched on the copper rods with a length of about 45 mm and a diameter of about 9 mm. Smaller, and the diameter of the hole to be punched is also very small, so the result of punching the hole is often biased, which not only consumes raw materials, but also the efficiency of punching is very low.

Domestic counterparts have invested manpower and material resources in the development of the above-mentioned problems, but they are not very satisfactory. The reason is mainly that holes of 1-2 mm are punched on the copper rods with a length of about 45 mm and a diameter of about 9 mm. Smaller, and the diameter of the hole to be punched is also very small, so the result of punching the hole is often biased, which not only consumes raw materials, but also the efficiency of punching is very low

[0003] The traditional drilling methods include bench drills and lathes. Although the efficiency of traditional bench drills is much higher than that of hand drills, the drilled holes often deviate from the original position due to the high impact force of the drill. Position, because only the drill bit rotates in one direction, the drilling rate is slow, and at the same time, because the drilled hole is not very vertical, resulting in a high scrap rate; the lathe is used for drilling, because the drilling rate is slow, so it often occurs when drilling. Uneven force directly leads to poor concentricity of the drilled holes

[0004] When drilling, the traditional method of fixing the workpiece is to use a three-jaw chuck or tooling. However, using the above fixing method, after clamping the workpiece, it is necessary to align it again, which greatly wastes time.
