Casting technique produces, and is then finished, and end face milling is indispensable one in back-plate process of manufacture among these
One of procedure, common machining tool fixture is more or less in fixed and positioning etc., and all there is a degree of deficiencies
And defect, cause machining accuracy low, defect rate is high, or even generates waste product.
Invention content
In view of the above problems existing in the prior art, the purpose of the utility model is to provide a kind of easy to assembly, positioning accurates
Accurate preceding back-plate vehicle centre bore and seam allowance fixture.
To achieve the above object, the technical solution adopted in the utility model is as follows：
Preceding back-plate vehicle centre bore and seam allowance fixture, include the bottom plate of disc-shape, and bottom plate center position is provided with
The pedestal of cylindrical shape, pedestal top are provided with fixed seat, back-plate are placed with above fixed seat（Hereinafter referred to as workpiece）, institute
The bottom plate both sides stated are symmetrically arranged with hold-down mechanism, and the hold-down mechanism is by cushion block, pressing plate, gasket, fastening nut, stud group
At the pressing plate center is set on stud, and pressing plate side is touched with cushion block end face, and the other side applies the workpiece in fixed seat
Downward pressure, and be locked by gasket and fastening nut；Positioning regulating mechanism is also set up on the bottom plate, it is described
Positioning regulating mechanism is made of axis pin, adjustment seat, adjusting nut, adjusting bolt, and pair in hold-down mechanism is arranged in the axis pin
Claim at position of center line, the camshaft clearance fit with workpiece, described adjusting bolt one end is connected by adjusting nut and adjustment seat
It connects, the other end is abutted with workpiece, completes positioning.
As an implementation, the cushion block is cylindrical shape, and bottom end is provided with threaded hole, and the bottom plate corresponds to position
The place of setting is provided with counterbore, and is connected and fixed by bolt and cushion block.
As an implementation, the stud is provided with fixing nut with back plate connections.
Compared to the prior art, the advantageous effects of the utility model are：
1, using the positioning regulating mechanism being made of axis pin, adjustment seat, adjusting nut, adjusting bolt, whens handling, directly will
Workpiece packs into axis pin, and the other end and adjusting bolt are against convenient and efficient, and adjusting bolt can be with adjustment length, use scope
Extensively.
2, using multiple hold-down mechanisms being made of cushion block, pressing plate, gasket, fastening nut, stud, clamping is firm, substantially
Degree reduces runout error, ensure that machining accuracy.
