Drilling and locating device for hollow spheres of sphere-connected handrail

Abstract

The invention discloses a drilling and locating device for hollow spheres of a sphere-connected handrail. The drilling and locating device comprises a machine tool working table, a guide rail, an oil pressure sliding table and a connection flat plate, wherein the guide rail is arranged on the machine tool working table; the oil pressure sliding table is arranged on the guide rail; a limiter is arranged on the oil pressure sliding table; two sensors are arranged on the machine tool working table; the connection flat plate is fixed on the oil pressure sliding table; two hollow sphere locating and fixing devices are arranged on the connection flat plate; the hollow sphere locating and fixing devices comprise locating parts and clamping parts; the locating parts comprise locating part bodies and floating locating taper pins; the floating locating taper pins consist of screw rods, nuts, cylindrical helical springs and locating taper pins; and the clamping parts comprise clamping part bodies and telescopic oil cylinders connected with the clamping parts. The drilling and locating device can accurately locate the hollow spheres on a machine tool and drill through the hollow spheres at one time, and can further realize continuous switching machining of two stations for hollow sphere drilling, so that the drilling efficiency for the hollow spheres is improved, and the manufacturing cost is greatly reduced.

Description

technical field [0001] The invention relates to a positioning device, in particular to a hollow ball drilling positioning device for a ball joint railing. Background technique [0002] At present, the ball joint railing is a commonly used railing protection facility. It is formed by welding several hollow balls on a column tube and then welding the soles (flanges and other components) on one end of the column tube. The hollow ball and The standpipe column is made of carbon steel or stainless steel, and the surface is hot-dip galvanized, so it has the advantages of novelty and beauty, convenient installation, durability, and maintenance-free. It is widely used in industrial and civil buildings for safety protection. The current market demand big. [0003] As one of the parts of the ball-joint railing, the hollow ball is usually formed by stamping steel pipes. After stamping, the spherical surface of the hollow ball has a pair of tapered holes that are symmetrical to the cent...

Problems solved by technology

[0003] As one of the parts of the ball-joint railing, the hollow ball is usually formed by stamping steel pipes. After stamping, the spherical surface of the hollow ball has a pair of tapered holes that are symmetrical to the center of the ball. If you need to drill more on the hollow ball When multiple centerlines pass through the hole in the center of the ball, it will be more difficult to accurately position the hollow ball on the drilling machine, which will not only reduce the processing efficiency of the hollow ball, but also increase the processing cost of the hollow ball
