Description

The cylindricality workpiece is the halving hole perforating device radially

(1) technical field

The utility model relates to a kind of perforating device, and especially a kind of cylindricality workpiece is the halving hole perforating device radially, is used for the radially processing of halving hole, belongs to steel member manufacture field.

(2) background technology

At steel member manufacture field, the cylindricality workpiece often need be processed radially halving hole, especially in the face of large-scale workpiece, processing radially, halving hole need use Digit Control Machine Tool usually, processing charges costliness not only, and, need make special fixture toward contact because workpiece size is excessive, further increased processing charges.

(3) summary of the invention

The purpose of this utility model is to overcome above-mentioned deficiency, provide a kind of can manual operations, the cylindricality workpiece of low processing charges halving hole perforating device radially.

The purpose of this utility model is achieved in that radially halving hole perforating device of a kind of cylindricality workpiece, and described device includes rotary disk, index dial, bearing support, positioner and drill jig; Described index dial is placed on the upper flange of rotary disk, is placed with workpiece to be processed on the described index dial, and described drill jig is arranged at the workpiece to be processed periphery; Described index dial card periphery is provided with several halving holes, two ends, described drill jig bottom are arranged with locating hole, the top is provided with boring, and the locating hole center of circle of two ends, described drill jig bottom symmetry and the central vertical line of boring are corresponding with three continuous halving holes on the index dial circumference; Described bearing support be uniformly distributed on the circumferencial direction of index dial lower end and the roller by the top and index dial under end in contact, described positioner is arranged at the bearing support right side and is connected to the halving hole of index dial by the alignment pin of its top setting.

The beneficial effects of the utility model are: adopt the utility model device, no longer need large-size numerical control machine to process, saved processing charges greatly.

(5) specific embodiment

Referring to Fig. 1, Fig. 2 and Fig. 8, the utility model relates to radially halving hole perforating device of a kind of cylindricality workpiece, includes rotary disk 1, index dial 2, bearing support 3, positioner 4 and drill jig 5; Described index dial 2 is placed on the upper flange of rotary disk 1, is placed with workpiece to be processed 7 on the described index dial 2, and described drill jig 5 is arranged at workpiece to be processed 7 periphery, and described index dial 2 upper disk surface peripheries are provided with several halving holes 2.1; Referring to Fig. 3, Fig. 4 and Fig. 5, two ends, described drill jig 5 bottom are arranged with locating hole 5.1, the top is provided with boring 5.2, and locating hole 5.1 centers of circle of two ends, described drill jig 5 bottom symmetry and 5.2 the central vertical line of holing are corresponding with three continuous halving holes on index dial 2 circumference; Referring to Fig. 6 and Fig. 7, described bearing support 3 is uniformly distributed on the index dial 2 lower end circumferencial directions and passes through roller and 2 times end in contact of index dial on top, and described positioner 4 is arranged at bearing support 3 right sides and is connected to the halving hole 2.1 of index dial 2 by the alignment pin 4.1 that its top is provided with.

During work: said apparatus is placed on the workbench 6, with in the halving hole 2.1 of alignment pin 4.1 insertion rotary disks 2 that rotary disk 2 is fixing, utilize locating hole 5.1 that drill jig 5 is fixing, first that uses that rig processes workpiece to be processed 7 at boring 5.2 places be halving hole radially, after processing first boring, take off drill jig 5, rotate the position that rotary disk 1 moves a halving hole, utilize locating hole 5.1 that drill jig 5 fixing backs are processed second radially halving hole with rig at boring 5.2 places once more, because two ends locating hole 5.1 centers of drill jig 5 and 5.2 the central vertical line of holing are corresponding with three continuous halving holes on index dial 2 circumference respectively, thereby guaranteed when rotary disk 1 turn over a halving hole apart from the time, second of boring 5.2 places processing radially the halving hole on halving hole and the index dial 2 be consistent, satisfy the five equilibrium requirement; Rotating rotary disk 1 successively processes finally and can process satisfactory radially halving hole in the periphery of workpiece to be processed 7.
