Abstract

The utility model belongs to a clamp for a large-scale planing machine and relates to a special-purpose clamp for machining super long keyways in a cylinder by the large-scale planing machine. The utility model is characterized in that the clamp comprises supporting seats with the same height, V-shaped iron members with the same height and hold-down plates; the cylinder is positioned via a pair of the V-shaped iron members with the same height; the central axis of the cylinder is corrected to be at the same vertical plane with an axis of a main shaft of a machine tool; the cylinder is tightly clamped by the hold-down plates; a cutting rod is disposed across the cylinder and a set of positioning holes of the supporting seats with the same height; the outer circle of the cutting rod is in a clearance fit with the positioning holes of the supporting seats with the same height and can freely slide; and through replacement or adjustment of a groove cutter on the cutting rod, the super long keyways in the cylinder can be machined according to design requirement. Therefore, planing is realized instead of drawing and machining of the super long keyways by the planing machine is realized, thus expanding application scopes for machining of equipment. Moreover, it is convenient to use the clamp, cost is saved, utilization rate of equipment is increased and the special-purpose clamp can be widely used for machining small batch of cylinders with super long keyways inside.

Description

Overlength keyway specific anchor clamps in the large-size planer processing cylinder barrel

Technical field

The utility model relates to a kind of large-size planer anchor clamps, relates in particular to overlength keyway specific anchor clamps in a kind of large-size planer processing cylinder barrel.

Background technology

In the steel mill metallurgical hydraulic cylinder commonly used a kind of mud hydraulic cylinder of beating is arranged, the overlength keyway is arranged in its cylinder barrel, process this keyway and have some problems: one, beat mud hydraulic cylinder long service life, production lot is very little, if at this product purchase broaching machine, in view of the flexibility (adaptability) of operation of broaching machine is wideless, equipment has high input, utilization rate is low, and cost is too high; Two, cooperation processing, man of the outsourcing factory resource that has broaching machine is rare, and the process-cycle is longer, has a strong impact on delivery date.

Summary of the invention

Main purpose of the present utility model is to draw to dig generation, on planer, realize the processing of overlength keyway, the processing scope of application of expansion equipment, address the above problem, provide a kind of installation simple, easy to use, save cost, can improve the interior overlength keyway specific anchor clamps of large-size planer processing cylinder barrel of utilization rate of equipment and installations.

The technical solution of the utility model is achieved in that overlength keyway specific anchor clamps in a kind of large-size planer processing cylinder barrel, comprises contour bearing, contour V shape iron and pressing plate; Contour bearing, pressing plate and platen are connected with screw, and contour V shape iron is placed directly on the platen face, and knife bar and contour bearing gap are slidingly matched.

Cylinder barrel is with one group of contour V shape iron location, proofread and correct cylinder barrel central axis and machine tool chief axis axis in same vertical plane, clamp cylinder barrel with briquetting, knife bar passes cylinder barrel and one group of contour bearing locating hole, knife bar cylindrical and contour bearing locating hole matched in clearance, can be free to slide,, can process overlength keyway in the cylinder barrel by designing requirement by changing or adjust the groove cutter on the knife bar.

The utility model has the advantages that: can realize drawing, on planer, realize the processing of overlength keyway with planer generation, the processing scope of application of expansion equipment, easy to use, save cost, can improve utilization rate of equipment and installations.

Description of drawings

Fig. 1 is the utility model mounting structure schematic diagram;

Fig. 2 is the utility model A-A generalized section;

Each unit number is in the accompanying drawing: the contour bearing of 1-cylinder barrel 2-groove cutter 3-

The contour V shape iron 5-of 4-knife bar 6-platen 7-pressing plate

The specific embodiment

As shown in Figure 1, the utility model is made up of contour bearing 3, contour V shape iron 4 and pressing plate 7, and contour bearing 3, pressing plate 7 and platen 6 usefulness screws are connected, and contour V shape iron 4 is placed directly on the platen face, and knife bar 5 and contour bearing 3 gaps are slidingly matched.

Its operation principle: cylinder barrel 1 is with one group of contour V shape iron 4 location, proofread and correct cylinder barrel 1 central axis and machine tool chief axis axis in same vertical plane, clamp cylinder barrel with briquetting 7, knife bar 5 passes cylinder barrel 1 and one group of contour bearing 3 locating hole, knife bar 5 cylindricals and contour bearing 3 locating hole matched in clearance, can be free to slide, by changing or adjust the groove cutter 2 on the knife bar, can process overlength keyway in the cylinder barrel by designing requirement, realize drawing, on planer, realize the processing of overlength keyway to dig generation, the processing scope of application of expansion equipment, easy to use, save cost, improve utilization rate of equipment and installations.
