Description
Technical Field
The utility model relates to a positioning device, in particular to a drilling positioning device for an oil cylinder and a headstock.
Background
The steel bar cutting machine is a tool used for cutting steel bars, is mainly used for cutting steel bars in a civil engineering in a fixed length mode, and is necessary equipment for a steel bar processing link. Compared with other cutting equipment, the cutting machine has the advantages of light weight, less energy consumption, reliable work, high efficiency and the like, and is widely applied to the field of mechanical processing. However, when the cylinder and the headstock of the steel bar cutting machine are installed, threaded holes need to be drilled on the side walls of the cylinder and the headstock, the precision requirement of the distance between the threaded holes on the cylinder or the headstock and the end surfaces of the cylinder or the headstock is extremely high, and the cylinder or the headstock cannot be normally installed due to slight deviation, so that the cylinder or the headstock is scrapped.
SUMMERY OF THE UTILITY MODEL
The utility model aims to solve the defects of the prior art, and provides the oil cylinder and headstock drilling positioning device which is simple in structure, reasonable in design, convenient to use, high in positioning accuracy and capable of improving the drilling efficiency.
The technical scheme adopted by the utility model for solving the technical problems is as follows: the utility model provides an hydro-cylinder, headstock drilling positioner, includes the ring flange, the geometric centre of ring flange puts and is equipped with the mounting hole, be equipped with the location axle in the mounting hole, the location axle is equipped with the position sleeve at the fixed cover in one side of ring flange, the position sleeve is equipped with holding ring, location screw thread, changeover portion toward the position sleeve tip by the ring flange in proper order, the holding ring butt is on the lateral wall of ring flange, the bottom of location screw thread extends to holding ring department, the position sleeve is equipped with the supplementary slotted hole that is used for drilling in location screw thread department, the location axle is equipped with fixed thread on the opposite side surface of ring flange, the location axle is equipped with the fixation nut who is used for mounting flange and location axle on fixed thread.
Preferably, the positioning sleeve and the end face of the positioning shaft are fixed by welding, the positioning shaft is machined by cast iron, and the positioning sleeve, the positioning ring, the positioning thread, the auxiliary slotted hole and the transition section are integrally machined by alloy steel.
Preferably, the positioning shaft is provided with a gasket between the flange plate and the fixing nut.
When the drilling machine is used, the drilling machine is arranged on the drilling machine through the flange plate, then the drill bit of the drilling machine is adjusted to be aligned with the auxiliary slotted hole, the oil cylinder or the headstock to be processed is sleeved on the positioning sleeve through the positioning thread until the end surface of the oil cylinder or the headstock abuts against the side wall of the positioning ring, and finally the drilling machine is driven to drill holes; the drilling machine has the advantages of simple structure, reasonable design, convenience in use, high positioning precision, capability of improving the drilling efficiency and the like.
