Description
Technical field
The utility model relates to a kind of Lathe Spindle Box, particularly a kind of jack catchs type lathe headstock of realizing two-way clamping.
Background technology
In recent years, along with the fast development of Digit Control Machine Tool, each lathe producer has released Digit Control Machine Tool product separately one after another, and these products can satisfy most of user's demand.The product that but lathe manufacturing firm is generally the user to be provided all is based on universal machine tools, does not provide and, special use efficient, high-precision at required some of some specific processing parts of user or specialized machine tool often have manufacturer.With numerically controlled lathe, its main spindle box of universal numerical control lathe has only an end that anchor clamps are housed, thereby part can only be finished turning processing at the one end, as if the part that all need process at two ends, traditional process is first processing parts one end and then turns around to process the other end, because workpiece to be machined is to be installed for twice by the back of turning around to finish processing, the part of having relatively high expectations for axiality often is difficult to reach required precision.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, provide a kind of and anchor clamps all are installed at the main shaft two ends, the part to be processed clamping once can be finished the jack catchs type lathe headstock of realizing two-way clamping of the processing technology such as cylindrical, end face, endoporus at two ends simultaneously.
For achieving the above object, the technical solution of the utility model is: a kind of jack catchs type lathe headstock of realizing two-way clamping, comprise the main shaft casing, be installed in the main shaft device in the main shaft casing, this main shaft device is made up of belt pulley that is installed in main shaft one end and the anchor clamps that are installed on the main shaft, it is characterized in that anchor clamps all being installed at the main shaft two ends, the hydraulic clamp that links to each other with two anchor clamps is installed in the main shaft between two anchor clamps, on main spindle box, be equipped with link to each other with above-mentioned hydraulic clamp into and out of hydraulic fluid port.
Be that the above-mentioned anchor clamps that are installed in the main shaft two ends are the three-jaw jig, two annular pistons are installed in the main shaft endoporus, removable being tightly connected of the external disc of the endoporus of annular piston and trunk-piston, form airtight cavity between the opposite face of two annular pistons and main shaft endoporus and the trunk-piston body, on the main shaft corresponding, have oilhole with cavity; In the annular piston space relative with each claw, " L " shape fork all is installed, the two ends of " L " shape fork link to each other with annular piston with claw respectively; At the main shaft two ends tubular pedestal is installed, what claw can move radially is installed on the tubular pedestal, the middle part of " L " shape fork fixes on the tubular pedestal by hinges fixing, form airtight cavity between tubular pedestal, main shaft endoporus and the annular piston, have the turnover oilhole on the main shaft corresponding with this airtight cavity.
Being connected between the two ends of above-mentioned " L " shape fork and claw and the annular piston is to adopt to have elongated slot at claw and annular piston corresponding position, and the two ends of " L " shape fork are placed on the connected mode in the elongated slot.
The technical solution of the utility model has following characteristics: 1, a machine tool is equivalent to two lathes.Because the utility model all is equipped with anchor clamps at the main shaft two ends, after once being installed, can finish the processing of main shaft two ends part simultaneously, operating efficiency is equivalent to two lathes, and disposable input of lathe, floor space, cost of labor etc., half of lathe of having only present processing part of the same type, and production efficiency is enhanced about more than once; 2, can significantly improve the precision of the machining accuracy of part to be processed, particularly axiality.When part to be processed is axial workpiece, because the processing that need not to turn around just can once be finished the processing at axial workpiece two ends, improved the axiality of part processing on the one hand, reduced the process that is installed of a part on the other hand; 3, this device is that main shaft device, chucking oil cylinder and anchor clamps three are placed in the short main shaft, the needs that casual labourer's part two ends clamp simultaneously and process have been realized, when processing than farm labourer's part, two playscript with stage directions devices can be installed on bed piece simultaneously, both two main shafts were installed, processed.
In sum, this device has that disposable less investment, working (machining) efficiency height, machine tooling size accommodation are big, the characteristics such as axiality height of part to be processed, is highly suitable for Digit Control Machine Tool, particularly uses on the specialized nc machine tool.
Description of drawings
Accompanying drawing 1 is the utility model structural representation.
The specific embodiment
As shown in Figure 1, main shaft 14 is by bearing 10 rotatable being fixedly mounted in the main spindle box 1, left end at main shaft is equipped with the belt pulley 2 that can drive main axis rotation, two ends, the left and right sides at main shaft are installed with tubular pedestal 3, on the tubular pedestal that is installed in two ends, the left and right sides that claw 5 in the three-jaw jig can radially move, two annular pistons about in the main shaft endoporus, being equipped with, removable being tightly connected of periphery of the endoporus of annular piston and trunk-piston body 8.Form airtight cavity between the periphery of the opposite face of left end annular piston 13 and right-hand member annular piston 11 and main shaft endoporus and trunk-piston body, on the main shaft corresponding, have oilhole 12 with cavity; In the space of corresponding of annular piston and each claw, " L " shape fork 6 all is installed, the two ends of each " L " shape fork are installed in respectively in the elongated slot of claw and annular piston corresponding section opening, and the middle part of " L " shape fork is fixed in the tubular pedestal by hinge 7; Between the tubular pedestal at main shaft two ends and main shaft endoporus and annular piston, form airtight cavity 9, have the turnover oilhole on the main shaft corresponding with this airtight cavity.
During use, workpiece to be machined is passed in three-jaw jig and the trunk-piston body 8, start and step up hydraulic system, in the cavity about this moment, hydraulic oil entered by oilhole 12 between two annular pistons, promote two annular pistons at two ends, the left and right sides, move to the left and right respectively, driving left end " L " shape fork rotates counterclockwise along hinge 7, drive right-hand member " L " shape fork and clockwise rotate along hinge 7, thus drive claw along main shaft diameter to moving to the center, realize the purpose of clamping work pieces.Because the tubular pedestal is fixedly mounted on the end face of main shaft, rotatablely moving of main shaft passes to workpiece by tubular pedestal, claw.After two-way clamping, the process finishing, the work of clamping hydraulic system reverse, pressure oil is by the turnover oilhole on the main shaft, enter and form in the airtight cavity 9 between two ends, main shaft left and right sides tubular end cap, main shaft endoporus and the annular piston, two annular pistons are thought to move in the middle of the main shaft about promotion, drive the reverse rotation of " L " shape fork, make claw unclamp workpiece, but this moment is with regard to workpiece loading and unloading.In order to install and locate needs, end face is equipped with end cap 4 in the left and right sides of main shaft, and claw is enclosed in the main shaft.
This device the shortlyest can be implemented two-way clamping, two-way processing to the workpiece about 200 ㎜ in above-mentioned two embodiment.When the length of workpiece surpasses 500 ㎜, two these lathe headstocks of cover can be installed on bed piece simultaneously, just can realize two main shaft processing.
This device is fit to be installed on the specialized nc machine tool very much.
