Description

Template workpiece processing frock with holes

Technical field

A kind of template workpiece processing frock with holes is the utility model is related to, relates generally to work piece holder field.

Background technology

In work pieces process, there are a large amount of template workpiece with holes.The characteristics of this kind of workpiece is mainly very thin thickness, in end face point Hole not of uniform size is furnished with, the fixture using routine is difficult effective fixation, and on the one hand fixed clamping face is excessive, causes in work Part interferes during boring milling to cutter, shakiness is on the other hand clamped, it is difficult to find effective fixing point.

Utility model content

For above the deficiencies in the prior art, the utility model proposes a kind of template workpiece with holes of stable fixed workpiece to add Work frock.

To reach above-mentioned purpose, the technical solution of the utility model is：Including frame, cylinder and the cylinder type being vertically arranged Expander, frame includes two risers being vertically arranged on base, horizontally disposed supporting plate and being horizontally fixed on riser The transverse slat of upper end, supporting plate both ends are fixed with riser, and transverse slat is provided with manhole, and manhole is inlaid in the middle part of expander Interior, the expander excircle above transverse slat is cut the circular shaft sidewall upper of cylinder type expander by axial wire cutting some Valve, the lower end of expander are fixed on supporting plate upper surface, and cylinder is fixed on the lower surface of supporting plate, and the output end of cylinder is to support Plate upper surface is extended into expander, is provided with rounding frustum in expander upper port, rounding frustum is provided with bolt, rounding vertically Frustum docks downwards the upper end for being fixed on cylinder output end by bolt, is fixed with the transverse slat upper surface of expander periphery some Support block.

Technical principle of the present utility model is as follows：Using this programme, when no progress clamping, cylinder drives rounding Frustum separates with expander upwards, i.e., now expander does not expand, and the diameter of expander keeps minimum normal condition.By work Expander is placed in the hole of workpiece, the end face of workpiece is supported by support block, Ran Houqi by the hole of part to its expander Cylinder of taking offence moves down rounding frustum, and rounding frustum will be extruded outwards expander, and the diameter of expander becomes to enter to be about to greatly Workpiece is locked at hole.

The beneficial effects of the utility model are as follows：The lower end of expander is fixed on supporting plate upper surface, while expander Middle part is inlaid on transverse slat, therefore when cylinder carries out expanding overstocked to expander, can sufficiently ensure the energy of expander Enough stable fixations, keep expander being capable of centralized positioning.By carrying out centralized positioning to the hole of workpiece, avoid carrying out workpiece Clamping, workpiece can be farthest protected, while to the face very little that workpiece is fixed, can prevent processing from being caused to process equipment Interference.

Further, the guide cylinder of nylon rubber material, the upper end of the guide cylinder are cased between expander and cylinder output end Upper end highly less than cylinder output end moves down the height of the limit, and guide cylinder to cylinder output shaft can be moved through It is oriented in journey, avoids the occurrence of crooked, causes expander uniformly to be expanded.

Further, also axial wire cutting is in some valves, the wire cutting of expander lower end and the line of upper end for the lower end of expander Cutting is spaced apart in expander excircle, and the wire cutting of expander lower end extends to the top of transverse slat, and each valve of expander is swollen It can be deformed when swollen, expander lower end is also carried out to wire cutting be easy to it preferably to deform being expanded.

Further, support block includes fixed sole piece, support column and spring catch, and fixed sole piece is fixed on the horizontal stroke of expander periphery On plate, fixed sole piece is provided with up-small and down-big shoulder hole vertically, and the lower end of support column is fixed in shoulder hole, the lower end of support column Provided with cylindrical projection, shoulder hole is locked support column by cylindrical projection, and support column is provided with pin-and-hole vertically, and spring catch is fixed on pin In hole, the upper end of spring catch is set for pyramidal structure and prominent pin-and-hole, can be by itself and workpiece by the way of spring catch Pin-and-hole is combined, and spring catch is entered in pin-and-hole, workpiece is positioned, and spring catch even closer can be matched somebody with somebody with workpiece Close.
