Abstract

The invention discloses a bar double-end-face drilling device and method and mainly relates to the technical field of drilling. The bar double-end-face drilling device comprises a total base; a processing unit, a support unit and two clamping units; the processing unit is arranged at one end above the total base in a sliding manner and is positioned on the outer side of the clamping units; the processing unit comprises a drill bit; the support unit is arranged on the total base and comprises a rotary disc, a middle support, a rotary unit and two side supports; the two clamping units are arranged on the total base in a sliding manner and are positioned on the two sides of the support unit; and each of the clamping units comprises a fixed support seat and a movable support seat. According tothe bar double-end-face drilling device, the support unit is cooperated with the two clamping units for clamping, the middle section of a bar is supported and clamped through the support unit, detaching is not needed during the entire drilling process, drilled holes in two ends are positioned at one time, the drilled hole in the second end face is cooperated with the support unit to rotate to drive the entire bar to rotate by 180 degrees without completely taking down the bar, and during the drilling process, the middle section of the bar is always supported through the support unit to ensurethe coaxiality of two end face holes.

Description

technical field [0001] The invention relates to a drilling device and a drilling method, in particular to a double-end surface drilling device and a drilling method of a rod. Background technique [0002] Bars generally refer to a material product whose cross-sectional shape is a simple figure such as a circle, square, hexagon, octagon, etc., and whose length is relatively large compared to the cross-sectional size, and is usually straight. Common bars usually refer to Most of them are steel with circular cross-section and a thickness of more than 20mm. The bar can be used in various industries and occasions after processing. The relatively large cross-sectional size brings great trouble to drilling, especially double-end drilling, which is easy to deform when clamping, and it is difficult to ensure the coaxiality of the two end holes, which ultimately affects the overall use of the bar. Therefore, It is very necessary to design a double-end drilling device for rods and a d...
