Rotatable metal pipe perforating machine

Abstract

The invention discloses a rotatable metal tube perforating machine which comprises a base, a fixed clamping assembly, an opposite moving clamping assembly, a feeding and discharging assembly and a drilling machine body, the drilling machine body is fixed to an operation station through the base, the fixed clamping assembly is arranged on one side of an upper table top of the base, and the opposite moving clamping assembly is arranged at the position opposite to the fixed clamping assembly. A longitudinal clamping block and a transverse clamping block which can conduct automatic clamping are arranged in the fixed clamping assembly and the opposite moving clamping assembly, automatic clamping of the oval pipe can be achieved, the opposite moving clamping assembly can be automatically adjusted according to the length of the oval pipe, the feeding and discharging assembly which can conduct automatic clamping is further arranged at the front end of the upper table face of the base, manual clamping is not needed, and the working efficiency is improved. The device has the advantages of being high in automation degree, high in punching precision and high in efficiency.

Description

technical field [0001] The invention relates to the field of metal punching, in particular to a rotatable metal punching machine. Background technique [0002] Conventional metal round hole punching only needs three claws to clamp to complete the fixing of the round pipe, but three claws cannot clamp unconventional pipes such as elliptical pipes. Generally, tooling that is consistent with the outer wall of the elliptical pipe is used for installation. The clamp is fixed, and then the elliptical tube is manually placed on the processing table with the tooling, and the holes are manually drilled with a drilling machine, and the drilling can only be carried out in the direction perpendicular to the machining table. When processing holes at a certain angle with the table, It is also mostly realized by the way of rotating the drill head, which has the disadvantages of poor drilling accuracy and low efficiency. A square, a first fastening bolt, a second fastening bolt and a drill...

Problems solved by technology

[0002] Conventional metal round hole drilling only needs three clamps to complete the fixation of the round tube, but the three clamps cannot clamp unconventional tubes such as elliptical tubes, and generally adopt tooling that is made to be consistent with the outer wall of the elliptical tube. Fix it with a clamp, and then use the tooling to place the elliptical tube manually on the processing table, and use the drill machine to punch holes manually, and can only punch holes in the direction perpendicular to the machining table. When processing holes at a certain angle with the table, It is also mostly realized by means of a rotary drill head, which has the disadvantages of poor drilling accuracy and low efficiency, such as an automatic rotatable drilling machine disclosed in the prior art (CN205380294U), which includes a base, a guide rail, a round Angle square, the first fastening bolt, the second fastening bolt and drilling shaft, the drilling shaft includes a drill bit, a rotating shaft, a small motor, an upper case and a lower case, the rear side of the upper case and the rear side of the upper end of the base pass through The first fastening bolt is rotatably connected, one side of the lower shell is provided with a vertical seam, and the second fastening bolt is arranged on the seam, and the fillet ruler is inserted into the seam with the first fastening bolt as the center of the circle , the edge of the rounded square is provided with a sliding seam, the second fastening bolt passes through the sliding seam, and a sliding rod is clamped at the front and rear ends inside the base, the sliding rod is equal in length, and its upper end can be rotatably fixed on a small motor On the bottom surface of the bottom surface, the lower end is rotatably connected with the sliding piece clamped in the guide rail to complete the adjustment of the drill shaft angle, and the adjustment is performed by visually measuring the fillet. Corresponding fixed, prone to deflection, affecting the accuracy of processing
