Abstract
The utility model relates to the technical field of drilling machining of annular plate type workpieces, in particular to a positioning and clamping device for drilling an annular plate type workpiece. The annular plate type workpiece is drilled after being scribed in the prior art, and is a large-sized thin plate type workpiece, so that the workpiece is extremely easy to deform after being machined. The positioning and clamping device consists of a bottom plate, a positioning sleeve, a trapezoidal bolt, a pressing nut, a pressing plate, fixed drilling sleeves and drilling templates, wherein the bottom plate is welded at the bottom of the positioning sleeve; an annular groove is formed in the bottom plate; an outlet is formed in each of the left and right sides of the annular groove; two open grooves are formed in axisymmetric directions in the positioning sleeve; the fixed drilling sleeves are arranged in positioning holes of the drilling templates; the drilling templates are arranged on workpieces; inner holes of the drilling templates are in clearance fit with the outer circle of the positioning sleeve; the trapezoidal bolt penetrates through the pressing plate, and the pressing plate is arranged in the open grooves of the positioning sleeve; and the pressing nut is screwed into the trapezoidal bolt. The device can be used for clamping and machining a plurality of workpieces at one time, and is accurate in positioning and convenient to operate.
Description
Technical field
The utility model relates to a kind of Drilling operation technical field of annular plate type part, specifically a kind of annular slab class Workpiece boring positioning clamping device.
Background technology
In the prior art, the Drilling operation of annular plate type part is to hole after adopting line, owing to be large-scale sheet type workpiece, the workpiece after the processing very easily produces distortion, affects product quality.
Summary of the invention
Order of the present utility model provides a kind of annular slab class Workpiece boring positioning clamping device, the problem that exists to solve above-mentioned prior art.
The technical scheme that its technical problem that solves the utility model adopts is: by base plate, abutment sleeve, trapezoidal bolt, clamp nut, pressing plate, fixedly drill bushing and bushing plate form; Base plate is welded on the bottom of abutment sleeve, and base plate is provided with a cannelure, and cannelure each side has an outlet, and the axis symmetry direction has two open slots on the abutment sleeve; The endoporus of bushing plate and abutment sleeve cylindrical matched in clearance; The width of pressing plate matches with the open slot of abutment sleeve; Abutment sleeve passes trapezoidal bolt, and bushing plate places above the workpiece on the base plate, and fixedly drill bushing is inserted in the locating hole of bushing plate, and pressing plate passes in the open slot that trapezoidal bolt is placed on abutment sleeve, by clamp nut pressing plate is fixed.
The beneficial effects of the utility model are, accurate positioning is easy to operate, once can process a plurality of workpiece, can realize fast positioning and clamping and the processing of workpiece, high efficiency.
Description of drawings
Fig. 1 is structure chart of the present utility model;
Fig. 2 is the top view of Fig. 1;
Fig. 3 is the structure chart after base plate and the abutment sleeve welding;
Fig. 4 is the top view of Fig. 3.
Among the figure: 1. base plate, 2. abutment sleeve, 3. trapezoidal bolt, 4. clamp nut, 5. pressing plate, 6. fixedly drill bushing, 7. bushing plate, 8. workpiece.
The specific embodiment:
Positioning clamping device is by base plate 1, abutment sleeve 2, trapezoidal bolt 3, clamp nut 4, pressing plate 5, fixedly drill bushing 6 and bushing plate 7 form, base plate 1 is welded on the bottom of abutment sleeve 2, base plate 1 is provided with a cannelure, cannelure each side has an outlet, and the axis symmetry direction has two open slots on the abutment sleeve 2; Trapezoidal bolt 3 is put into the workbench dovetail groove, and abutment sleeve 2 passes trapezoidal bolt 3, with bolt base plate 1 is fixed on the workbench; Workpiece 8 is placed on the base plate 1, fixedly drill bushing 6 is inserted in the locating hole of bushing plate 7, and bushing plate 7 is placed on the workpiece, the endoporus of workpiece 8 and bushing plate 7, abutment sleeve 2 cylindrical matched in clearance, pressing plate 5 passes trapezoidal bolt 3 and is placed in the open slot of abutment sleeve 2, and clamp nut 4 screws in trapezoidal bolt 3.
During work, at first trapezoidal bolt 3 is placed in the dovetail groove of common driller workbench, again abutment sleeve is passed trapezoidal bolt 3, with bolt base plate 1 is fixed on the workbench; Workpiece 8 endoporus pass abutment sleeve 2 cylindricals and are placed on the base plate 1, according to the height of abutment sleeve 2, can place a plurality of workpiece, again bushing plate 7 is passed abutment sleeve 2 cylindricals and be placed on the workpiece, then pressing plate 5 is placed in abutment sleeve 2 open slots, pushes down bushing plate 7 usefulness clamp nuts 4 and tighten and get final product.
Iron filings after the drilling processing directly drop in the cannelure on the base plate 1, and there are two outlets the side, and the iron filings of being convenient in the groove are discharged.
