Abstract
The utility model relates to a workpiece positioning clamping device which mainly comprises a positioning clamping sleeve, a limiting pin, a spring and a check ring. The positioning clamping sleeve, the spring and the check ring are sequentially installed on a power head from bottom to top, and the limiting pin is arranged in a rectangular hole of the positioning clamping sleeve and fixed to the power head.
Description
Technical field
The utility model relates to a kind of positioning clamping device used while giving Workpiece boring, is applied on semi-automatic drilling machine.
Background technology
At present, with semi-automatic drilling machine, give cylindrical and bore position when the Workpiece boring in cylinder axle center, the positioning clamping device using is a lot, but they all separate, locate and clamping be two independently device, all be arranged on workbench, and clamping device has independently power drive mechanism, such positioning clamping device volume compared with large, part is many, transmission link is many, make trouble.
Summary of the invention
The object of utility model.
The positioning clamping device that provides a kind of positioner and clamping device to be integrated is provided the purpose of this utility model, because this device is arranged on semi-automatic drilling machine unit head (hereinafter referred to as unit head), by the positioning and clamping that has moved up and down workpiece of unit head, so do not need independent power drive mechanism.This device has compact conformation, volume is little, part is few, the feature of easy processing.
Technical scheme.
A kind of work piece positioning tightly installs, it is mainly by location gripping sleeve, spacer pin, spring, back-up ring forms, gripping sleeve lower surface, location is circular cone side view, in circular cone side, top shaft core position is processed with circular hole, in location, gripping sleeve lower end side is processed with a circle chip-removal hole, in location, clamp side, set upper side vertical direction and be processed with an oblong aperture, location gripping sleeve is sleeved on the lower end of unit head by its upper end, spacer pin is placed in the oblong aperture of clamping side, set upper side, location, and be fixed on unit head, spring fitting is on unit head, its lower end clamps set upper side face with location and contacts, its upper end contacts with the lower surface of back-up ring, back-up ring is fixed on unit head.
Beneficial effect.
Owing to having adopted such scheme, can realize positioner and clamping device is integrated and do not need the positioning clamping device of independent power drive mechanism, this device has compact conformation, volume is little, part is few, the feature of easy processing.
Accompanying drawing explanation
Accompanying drawing is structure of the present utility model and sketch is installed.
The specific embodiment
By reference to the accompanying drawings, the utility model is mainly comprised of location gripping sleeve 6, spacer pin 3, spring 2, back-up ring 1.Gripping sleeve 6 lower surfaces, location are circular cone side view, in circular cone side, top shaft core position is processed with circular hole, being convenient to drill bit 5 passes through, in location, gripping sleeve 6 lower end side are processed with a circle chip-removal hole, in location, gripping sleeve 6 upper side vertical directions are processed with a slot, location gripping sleeve 6 is sleeved on the lower end of unit head 4 by its upper end, and can on unit head 4, slide up and down.Spacer pin 3 is placed in the slot of gripping sleeve 6 upper ends, location, and is fixed on unit head 4.Spring 2 is arranged on unit head 4, and its lower end contacts with gripping sleeve 6 upper surfaces, location, and its upper end contacts with the lower surface of back-up ring 1, and back-up ring 1 is fixed on unit head 4.
Location of the present utility model and fastening are: on the workbench of semi-automatic drilling machine, by feed mechanism, workpiece is delivered to the below of location gripping sleeve 6, be in the scope that covers of circular cone side shape end face, unit head 4 moves down under dynamic action, because gripping sleeve 6 lower surfaces, location are circular cone side shape, so gripping sleeve 6 lower surfaces, location can match with the crossing circle forming of cylindrical side and upper surface of workpiece automatically, at this moment, the axle center of unit head 4 (being the center of drill bit) and axle center and the workpiece axis coinciding of locating the shape bottom surface, circular cone side of gripping sleeve 6, unit head 4 continues to move downward, spring 2 is compressed, workpiece is clamped by spring 2 elastic force, unit head 4 continues to move downward, drill bit 5 starts to hole on workpiece, bored behind hole, unit head 4 starts to rise, spring 2 starts to uphold, at this moment be still positioned gripping sleeve 6 of workpiece clamps, drill bit 5 is from the interior extraction of holing, unit head 4 continues to rise, when on the gripping sleeve 6 of location, the upper end of oblong aperture contacts with spacer pin 3, unit head 4 rises together with location gripping sleeve 6, workpiece is no longer clamped, workpiece is removed by unloading mechanism, now a drilling operating completes.
