Abstract
The utility model relates to an indexing workbench and a positioning structure thereof. The indexing workbench is of a rotating device which is placed horizontally for realizing angle positioning and can conveniently and quickly realize the circumferential angle positioning with multiple specifications and different equal division requirements. The indexing workbench is used for using occasions with the need of performing circumferential positioning, such as drilling machines, welding and cutting equipment, marking equipment and the like. The indexing workbench is particularly suitable for matching with a radial drilling machine for processing hole series with the different circumferential equal division requirements of 600-2500 circular disc (ring) type parts. The main parts of the indexing workbench comprise a rotating disc, a chassis, a positioning bolt and a rotating body. The chassis is fixed on a support and placed horizontally. The rotating disc is covered on the chassis and can realize the rotation relative to the chassis through a steel ball. A workpiece can rotate along with the rotating disc, a positioning hole series is processed on the back surface of the rotating disc according to the indexing requirements of the workpiece, and angle scale marks corresponding to the positioning hole series are arranged on the outer cylindrical surface. An angle pointer is used for reading an angle value. When the rotating disc rotates to the angle position required by the processed workpiece, the indexing positioning is realized by inserting the positioning bolt mounted on the chassis into the positioning hole on the rotating disc.
Description
Technical field
The utility model belongs to general control or regulating system field in the International Classification of Patents " analysis and survey control technology ", specially refers to the positioning control of angle.
Background technology
The processing of big flange bolt hole, conventional method adopt bore template or artificial line that bolt hole is positioned.Different size number of bolt holes in flange amount is different, requires the angle of five equilibrium also different, uses Template Location boring, and bushing plate input specification is many, and cost is big.The bushing plate sole mass of simultaneously big specification flange is big, and loading and unloading are installed inconvenient, and overhead time is long, influences the raising of production efficiency; The method efficient that realizes branch location such as flange hole with artificial line is lower, and positioning accuracy can not get guaranteeing.
Summary of the invention
The purpose of the utility model is the technical barrier that solves diameter 600～2500 disks (ring) type hole in piece part processing circumference calibration location.
The technology contents of the utility model is: a kind of index table and location structure thereof; It is characterized in that index table comprises rotary disk (1), chassis (3), fastening screw (4) and revolving body at least; Rotary disk (1) covers on the chassis (3); Rotary disk (1) and chassis (3) opposite face are processed with positioning ring groove, and rotary disk (1) realizes with the concentric locating on chassis (3) through revolving body and relatively rotate that rotary disk (1) bottom surface is processed with the five equilibrium locating hole by the calibration requirement and is; Fastening screw (4) is installed on the chassis (3), and the locating hole that fastening screw (4) inserts on the rotary disk (1) is realized the calibration location.
Be processed with positioning ring groove on described rotary disk (1) and chassis (3), its shape is: V-arrangement or trapezoidal or circular oval or the parabola shaped or hyperbola of rectangle.
Described revolving body is steel ball (2), cylindrical roller or taper roller.
Calibration locating hole processing on the described rotary disk (1) is arranged on the lower surface of rotary disk (1).
Described calibration location is to go up locating hole and be installed in chassis (3) and go up fastening screw and cooperates realization to locate through rotary disk (1).
The active force mode of described fastening screw (4) turnover locating hole is spring force, manual, pneumatic or hydraulic pressure.
Described fastening screw (4) is installed in the locating hole reeve of going up on realization and the rotary disk (1) on chassis (3) and shifts out.
The index table location structure is characterized in that realizing that rotary disk (1) and chassis (3) concentric locating structure are: rotary disk (1) and chassis (3) go up that processing concave-concave positioning ring groove or rotary disk (1) go up that processing bulge loop face and chassis (3) go up that the processing positioning ring groove matches or rotary disk (1) is gone up processing positioning ring groove chassis (3) and upward processed the bulge loop face and match.
The utility model has the advantages that: the circumference angle orientation that makes things convenient for branch requirements such as many specifications of Rapid Realization difference.Positioning accuracy is reliable and stable, and is simple to operate, and labour intensity is low.
