Description
Technical field
The utility model relates to the anchor clamps field, is specially a kind of multi-roller mill backing bearing and grinds and cut anchor clamps.
Background technology
After the multi-roller mill backing bearing outside diameter grinds and cuts, require maintenance high running accuracy and dimensional accuracy, and the bearing that has requires under the unseparated condition of outer ring, rolling element and retainer bearing outside diameter ground and cuts, so require the comparison harshness to grinding the anchor clamps of cutting external diameter again, the jig Design difficulty is bigger.The present high-accuracy clamp of dependence on import always, along with the production domesticization of the increasing and back lining bearing of multi-roll mill, the anchor clamps price height of external production, the shortcoming of narrow application range become increasingly conspicuous.As: ripple shell type clamp power is little, applicability is narrow, cost an arm and a leg; And the fluid pressure type fixture operation loaded down with trivial details, cost an arm and a leg, or the like.
The utility model content
The purpose of this utility model is to provide a kind of multi-roller mill backing bearing to grind and cuts anchor clamps, solves problems such as the external anchor clamps price height of producing, narrow application range.
The technical solution of the utility model is:
The multi-roller mill backing bearing grinds cuts anchor clamps, these anchor clamps are provided with mandrel, cone, spring expands, internal diameter is that the face of cylinder, external diameter are that the cone of taper seat is set on the mandrel, cone outer surface and external diameter are that the face of cylinder, internal diameter are that the bloated spring of taper seat is slidingly matched by the conical surface, and the spring outer surface that expands is installed back lining bearing.
Described multi-roller mill backing bearing grinds cuts anchor clamps, and the spring outside of expanding is connected with the spring tense-lax nut that expands.
Described multi-roller mill backing bearing grinds cuts anchor clamps, and the spring that expands, the spring tense-lax nut that expands have notch respectively vertically, and the spring that expands, the spring tense-lax nut that expands connect by notch.
Described multi-roller mill backing bearing grinds cuts anchor clamps, these anchor clamps also are provided with base plane, pressing plate, pressing plate packing ring, panel nut, the both sides of cone are respectively equipped with base plane and the pressing plate that is installed on the mandrel, base plane contacts with two end faces of workpiece respectively with pressing plate, base plane and pressing plate holding workpiece are between the two, and the outside of pressing plate is provided with pressing plate packing ring and the panel nut that is installed on the mandrel.
Described multi-roller mill backing bearing grinds cuts anchor clamps, and mandrel and cone interference fits become one structure, and cone is concentric with the center hole at mandrel two ends.
The beneficial effects of the utility model are:
1, anchor clamps are safe and reliable.The anchor clamps spring that expands produces enough big expansive force, has adopted pressure plate structure simultaneously, and bearing grinds that to cut the bearing process safe and reliable again under the protection of dual strength.
2, anchor clamps full-enclosed structure.Cut in the bearing process grinding, bearing assembly is in the full closeding state of anchor clamps, guarantees that abrasive dust can not enter in the bearing, is semi-enclosed structure and external some anchor clamps of producing adopt.
3, anchor clamps adaptability is strong.The utility model anchor clamps have the wide characteristics of interior fourth contact size adaptability, and the spring bulk that expands is big, can reach 1mm, and more external anchor clamps bulks of producing are 0.2mm.This shows that the utility model anchor clamps are applied widely, this point is that the external anchor clamps of producing are beyond one's reach.
4, anchor clamps precision height.Adopt the utility model anchor clamps, bearing grinds again to be cut the footpath, back and jumps and can reach 0.005mm, because anchor clamps have the base plane structure, bearing grinds again to be cut back external diameter vertical difference and can reach 0.004mm, is that high-precision back lining bearing grinds and cuts anchor clamps.
5, anchor clamps life-span height.Because the jig main body cone has partly adopted high abrasion resisting material, the spring that expands has then adopted the high resiliency deformable material, and special notching construction is arranged, make the spring that expands that high strain promptly be arranged in clamping process, also can partly not damage simultaneously bearing roller and jig main body cone.
6, the low cost of anchor clamps.Compare with the anchor clamps of external production, 1/200 of the not enough external anchor clamps price of producing of the material of the utility model anchor clamps, manufacturing and cost of labor, and have that clamp structure is simple, material is common, be easy to characteristics such as processing and manufacturing.
7, the operability of anchor clamps.The utility model anchor clamps are that theory of mechanics clamps bearing, and the tense-lax of a nut can realize the clamping of bearing or move back and unload, and anchor clamps are shaped on the lifting structure, are convenient to operator's clamping bearing, alleviate manual labor, and the clamping bearing is safe and reliable, convenient; And external some anchor clamps of producing utilize the hydraulic principle machining bearing, operate more loaded down with trivial details.
8, the utility model can be widely used in grinding and cut rib and do not had all kinds of back lining bearing external diameters of rib, as: biserial, three row back lining bearings etc.
In a word, the utility model is compared with the anchor clamps of external production, have the precision height, clamping force is big, applicability is wide, the life-span is high, cost is low, workable and be easy to characteristics such as processing and manufacturing, can replace the anchor clamps of external production fully.
