Abstract
A round-hole gear blank finish turning clamp structurally comprises a power source, a pull rod, a cylindrical spring core shaft, a gasket, a rubber washer, a spherical gasket and a screw nut. One end of the pull rod is connected with the power source mounted on the left side of a machine tool spindle box; the other end of the pull rod penetrates a main shaft of the spindle box, a chuck body and the cylindrical spring core shaft to be sleeved with the spherical gasket and fixed by the screw nut; a base of the cylindrical spring core shaft is connected with the machine tool chuck body through a bolt and is corrected, and the diameter of the outer circle of the cylindrical spring core shaft is slightly smaller than that of a round hole of a gear blank; and a hollow structure is adopted in the cylindrical spring core shaft; and the cylindrical spring core shaft is split from the root and is evenly divided into four pieces, and 120-degree chamfers are arranged on the open end face of the cylindrical spring core shaft. The cylindrical spring core shaft is sleeved with the gasket; and the left end of the gasket is in tight fit with the bottom end face of the cylindrical spring core shaft, and the rubber washer is embedded into an annular groove in the right end of the gasket. The contact surface of a curved surface of the spherical gasket and the open chamfered end face of the cylindrical spring core shaft is small. In the clamping work process, an annulus can be formed by the contact surface, and the centering precision is high.
Description
Technical field
The present invention relates to gear blank clamp for machining, specifically the manufacturing and designing of a kind of circular hole gear blank finish turning special fixture.
Background technology
In Gear Processing production process, if lathe, cutter, operation layout, fixture are constant, the machining accuracy of gear is mainly subject to restriction and the impact of the machining accuracy of gear blank, and gear blank machining accuracy is directly connected to the final precision of gear product.Due to the necessary link that circular hole gear blank finish turning is in high class gear Product processing operation, and the technological deficiency that the gear blank lathe finish fixture used exists, cause Product processing efficiency low, low precision, affect the assembling of circular hole gear product, running and service life.The circular hole gear blank finish turning processing of current gear enterprise generally adopts elastic central spindle and conical core shaft fixture, and the former clamping gear blank is convenient, and efficiency is high, but low precision, and end face and cylindrical are beated greatly.The latter's clamping is inconvenient, and working (machining) efficiency is low, and gear blank clamping all needs to take off conical core shaft, and knock gear blank or conical core shaft with copper rod or nylon hammer and make the two separately or be locked, labour intensity is large; Simultaneously conical core shaft frequently easily causes well damage to need to change owing to knocking, though gear blank end face after processing and cylindrical are beated little, but processing cost is high.
Summary of the invention
The present invention is directed to the technological deficiency that existing circular hole gear blank lathe finish fixture exists, provide the gear blank end face of easy to operate efficient, the processing of a kind of clamping and cylindrical to beat the finish turning special fixture little, precision is high.
The present invention is achieved through the following technical solutions:
A kind of circular hole gear blank lathe finish fixture, its structure comprises power source, pull bar, cylindrical spring mandrel, pad, rubber washer, spherical washer, nut.Described pull bar one end is connected with the power source be arranged on the left of lathe headstock, and the other end, through after headstock spindle and chuck body and described cylindrical spring mandrel, is inserted in the described nut of described spherical washer and fixes; The pedestal of described cylindrical spring mandrel to be connected with adaptor socket body for machine tool with bolt and to correct, and its outside diameter is slightly less than gear blank Circularhole diameter, cylindrical spring mandrel adopts hollow-core construction, it is cut open from root be divided into 4, there are 120 degree of chamferings openend; Described pad is enclosed within described cylindrical spring mandrel, pad left end and cylindrical spring mandrel bottom face tight fit, and the right-hand member cannelure of pad is embedded in described rubber washer; The curved surface of described spherical washer and the contact surface of described cylindrical spring mandrel opening chamfering end face little, during clamping work, can to form annular centering precision high for contact surface.
During work, by gear blank circle hole sleeve on described cylindrical spring mandrel, start described power source, complete horizontal direction and clamp movement left, drive described pull bar horizontal left simultaneously, described nut on it moves and impels described spherical washer to press described cylindrical spring end face of mandrel 120 degree of chamferings, cause the radial deformation that diameter swells, thus while gear blank being close to be enclosed within the described pad right side on described cylindrical spring mandrel, eliminate the radial clearance of its endoporus and cylindrical spring mandrel and clamp gear blank, starting the finish turning processing of gear blank.Special fixture of the present invention can accurately clamp gear blank securely and rotate together with main shaft, special fixture can eliminate the gap between gear blank endoporus and described cylindrical spring mandrel, gear blank inner face and described pad are close to, special fixture and gear blank assembly good rigidly, positioning stablity is reliable.The curved surface of described spherical washer and the contact surface of described cylindrical spring mandrel opening chamfering end face little, when spherical washer makes described cylindrical spring mandrel clamp, the distortion of each reed is tending towards a stationary value, and it is high that contact surface can form ring gear blanks centering precision.After gear blank completion of processing, power source completes horizontal direction and unclamps movement to the right, drive described pull bar simultaneously level move to right, described nut on it is no longer exerted pressure to described spherical washer, the elastic deformation of described cylindrical spring mandrel is eliminated, recover gap between gear blank endoporus and cylindrical spring mandrel, thus the gear blank processed can be taken off easily, be loaded on gear blank to be processed.
Beneficial effect of the present invention is:
The technology of the present invention has: 1.Working (machining) efficiency is high: gear blank clamping removal operation is convenient and swift, and labor intensity of operating staff is low.2。Machining accuracy is high: the gear blank end face of processing and cylindrical are beated little, constant product quality.3。Processing cost is low: after working (machining) efficiency and product qualified rate significantly improve, and can reduce cost of goods manufactured.
