The centralized positioning clamping device is mounted in the centers of a support plunger pin and a positioning pin of the machine tool in prior art, the excircle of the extended three clamping jaws is machined according to the size of the central hole of a workpiece, the three clamping jaws extend and retract synchronously, the centralized positioning clamping device realizes accurate positioning, supports the inner hole tightly and realizes the clamping of the workpiece. The utility model has the beneficial effects that: the positioning is accurate, the clamping is reliable, the workpiece generates no sway during hole expanding process, the position accuracy of the screw hole and the central hole after machining is high.
Description
Technical field
The utility model relates to a kind of lathe positioner, specifically is that a kind of multi spindle drilling machine centralized positioning clamps device.Be specially adapted to the spoke multi spindle drilling machine centralized positioning clamping work pieces of automotive wheel industry.
Background technology
At present, need in the spoke processing screw hole of spoke mesopore periphery is dashed the back chambering process, it is to carry out reaming processing with the screw hole location behind mesopore and screw hole that present stage adopted more, because the screw hole diameter is less, the rigidity deficiency, and do not have clamping device, workpiece can rock in the workpiece process, the position degree of processed workpiece mesopore and screw hole is relatively poor, for requiring tighter exported product, can not satisfy product requirement.
Summary of the invention
In order to improve the position degree precision of mesopore and peripheral screw hole, the utility model provides a kind of multi spindle drilling machine centralized positioning to clamp device.Be installed on the multi spindle drilling machine, the location that is used for spoke clamps.
The utility model is realized with following technical scheme: a kind of multi spindle drilling machine centralized positioning clamps device, comprises cylinder body, is installed in piston, guide pin bushing, awl core, dog plate, claw, spring and guide cover in the cylinder body; Guide pin bushing is contained on the bar of piston, and dog plate is installed above the guide pin bushing, and dog plate is fastened on the cylinder body; Annular gathering sill is arranged on dog plate, and claw and spring are installed in the gathering sill, on the bar of piston, be positioned in the claw endoporus the awl core, guide cover is installed in the top of awl core, the guiding cover screw is fastened on the dog plate.
This positioning clamping device is installed in the center of former support pin of lathe and alignment pin, and the cylindrical after three-jaw stretches out is by the processing of workpiece mesopore size, the three-jaw synchronization telescope, and accurately location, stretching endoporus are realized the clamping to workpiece.
Useful result of the present utility model is: accurate positioning, reliable clamping does not produce in the workpiece reaming process and rocks, the position degree precision height of processing rear bolt hole and centre bore.
Description of drawings
Below in conjunction with accompanying drawing the utility model is further specified.
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is a vertical view of the present utility model.
Among the figure: 1, guide cover, 2, claw, 3, spring, 4, dog plate, 5, cylinder body, 6, piston, 7, two way seal, 8, guide pin bushing, 9, sealing, 10, the awl core, 11, nut.
The specific embodiment
As depicted in figs. 1 and 2, the multi spindle drilling machine centralized positioning clamps device and is made up of cylinder body 5, the piston 6, guide pin bushing 8, awl core 10, dog plate 4, claw 2, spring 3 and the guide cover 1 that are installed in the cylinder body 5; Piston 6 is provided with two way seal 7; Guide pin bushing 8 is contained on the bar of piston 6, and dog plate 4 is installed above the guide pin bushing 8, and dog plate 4 usefulness screws are fastened on it on cylinder body 5; Annular gathering sill is arranged on dog plate 4, and claw 2 and spring 3 are installed in the gathering sill, in the present embodiment, establish 3 claws, and 3 claws are distributed in the gathering sill of dog plate 4, slide in the gathering sill of dog plate.Awl core 10 is arranged in claw 2 endoporus and is installed on the bar of piston 6, and is fastening with nut 11; The endoporus of claw 2 matches with the cylindrical of awl core 10, and the shape unanimity.Guide cover 1 is installed in the top of awl core 10, and guide cover 1 usefulness screw is fastened on the dog plate 4.The certain angle of outer round belt of guide cover 1 makes things convenient for the workpiece location.The endoporus of claw 2 cooperates with the cylindrical of awl core 10, and the shape unanimity.
Principle is: drive the awl core by the reciprocating motion of piston in cylinder body and move up and down, claw under the effect of spring and awl core synchronization telescope to clamp, to unclamp workpiece.When the logical oil of inferior part of the cylinder block hydraulic fluid port, piston 6 moves upward, and drives awl core 10 and moves upward, and the interior claw 2 of gathering sill that is distributed in dog plate 4 inwardly shrinks under the effect of spring 3, unclamps workpiece.When the logical oil of cylinder body top hydraulic fluid port, piston 6 moves downward, and drives awl core 10 and moves downward, and claw 2 overcomes the active force of spring 3 and outwards upholds clamping work pieces under the effect of awl core.
