Abstract
A floating type end face driving chuck comprises a tip base, a connecting body, a body and a connecting plate, wherein the tip base, the connecting body, the body and the connecting plate are sequentially and fixedly connected. A tip is arranged at the center of the tip base. A push rod is arranged at the center of the body. A limiting pin is arranged on the push rod. A limiting groove matched with the limiting pin is formed in the push rod. One end of the push rod is fixedly connected with the tip, and the other end of the push rod is fixedly connected with the output end of an oil cylinder of a machine tool. Driving pins are further arranged in the tip base, surround the tip and are connected with the push rod through a lever mechanism. The driving pins and the tip form a structure for fastening a workpiece and are movably connected in an inclined mode to form the structure with the tip portion of the tip serving as the axis. The structure has a workpiece clamping function and a workpiece releasing function through axial movement of the driving pins. According to the floating type end face driving chuck, complex outer circle shaft type parts are clamped at a time, stability is high, the structure is simple, no auxiliary device is arranged, maintenance is simple and convenient, and coaxiality and surface smoothness of the workpiece are ensured.

In the conventional processes of axial workpiece, often run into that workpiece turns around and the problems such as the part centering, secondary tool setting, programming, modification parameter, the workpiece that cause crush of attaching, these problems are generally carried out respective handling according to technological design personnel or operator's experience, although artificial intervention can guarantee the precision of part processing to a certain extent, but the solution of this routine can not guarantee the high accuracy axiality of shaft element, again because the operations such as continuous renewal part have reduced working (machining) efficiency.
Summary of the invention
For the problems referred to above, the one that aims to provide the utility model realizes the outer circular shaft-type parts of clamped one time complexity, good stability, simple in structure, it is without servicing unit, convenience easy to maintenance, and can effectively solve the floating type end face drive chuck of the axiality problem of the precision component that in traditional handicraft scheme, secondary clamping brings.
Technical solution of the present utility model is:
A kind of floating type end face drive chuck, comprise the dead head being connected successively, connect body, body and terminal pad, the center of described dead head is provided with top, the center of described body is provided with push rod, described push rod is provided with spacer pin, described push rod is provided with the stopper slot mating with spacer pin, one end of described push rod is fixedly connected with top, the output of the other end and lathe oil cylinder is connected, it is characterized in that: described dead head is interior around the top drive pin that is also provided with, described drive pin is connected with push rod by leverage, the structure of described drive pin and a fastening workpiece of top formation, this structure is partial to flexible connection take top tip as axle.This structure realizes by the axially-movable of drive pin the function that clamps and unclamp to workpiece.
Above-mentioned floating type end face drive chuck, its special character is: also comprise the tailstock centre that is fixed workpiece with dead head, being centered close on same level line of described tailstock centre and dead head.
Above-mentioned leverage is made up of connecting axle and jacking block, and one end of described connecting axle is connected with push rod, the other end is flexibly connected with jacking block, and the other end of described jacking block is connected with drive pin.
One end that above-mentioned drive pin is connected with jacking block is spheroidal, and the end of this spheroidal is embedded in the corresponding circular hole that jacking block is provided with.
Above-mentioned drive pin is 4.
The utility model has the advantage of: top for location, the tailstock centre clamping work pieces of workpiece is to coordinate the top assurance workpiece two ends of passing forward concentric, utilize " cutter formula " structure drive pins of four equidirectional high rigidity to stretch out top tight workpiece end face simultaneously and drive workpiece rotation, realize the outer circular shaft-type parts of clamped one time complexity, good stability, simple in structure, it is without servicing unit, convenience easy to maintenance, to guarantee axiality and the surface smoothness of workpiece.
Accompanying drawing explanation
The profile of the floating type end face drive chuck in Fig. 1 embodiment 1.
Drawing reference numeral explanation: 1-dead head, 2-connection body, 3-body, 4-spacer pin, 5-terminal pad, 6-push rod, 7-connecting axle, 8-jacking block, 9-drive pin, 10-top, 11-tailstock centre, 12-stopper slot.
The specific embodiment
Embodiment 1
A kind of floating type end face drive chuck, comprise the dead head 1 being connected successively, connect body 2, body 3 and terminal pad 5, the center of dead head 1 is provided with top 10, the center of body 3 is provided with push rod 6, push rod 6 is provided with spacer pin 4, push rod 6 is provided with the stopper slot 12 mating with spacer pin 4, one end of push rod 6 is fixedly connected with top 10, the output of the other end and lathe oil cylinder is connected, in dead head 1, be also provided with drive pin 9 around top 10, drive pin 9 is connected with push rod 6 by leverage, drive pin 9 and top 10 forms the plane of a fastening workpiece, this plane is flexibly connected as being partial to take top 10 tip axle.This axle deflection is flexibly connected in the scope that is generally rotated in 0-15 °.Leverage is made up of connecting axle 7 and jacking block 8, and one end of described connecting axle 7 is connected with push rod 6, the other end is flexibly connected with jacking block 8, and the other end of described jacking block 8 is connected with drive pin 9.One end that drive pin 9 is connected with jacking block 8 is spheroidal, and the end of this spheroidal is embedded in the corresponding circular hole that jacking block 8 is provided with.Drive pin 9 is 4.
Embodiment 2
Other structures are the same with embodiment, for little workpiece said structure, length or large-scale workpiece, it is excessive that the loose other end adds man-hour rocking tendency, bad operation, therefore need a tailstock centre 11, tailstock centre 11 and dead head 1 are fixed the tailstock centre 11 of workpiece, and described tailstock centre 11 is centered close on same level line with dead head 1.In this example, drive pin 9 is 4.
Referring to Fig. 1, when work, the output of lathe oil cylinder promotes push rod 6, push rod 6 promote top 10 and leverage in connecting axle 7, connecting axle 7 promotes jacking block 8 and then drives drive pin 9, forms the plane fixation workpiece of a fastening workpiece at drive pin 9 and top 10, and top 10 stretch out top tight workpiece end face with drive pin 9 drives workpiece rotation, because drive pin 9 is connected with leverage, the plane of above-mentioned fastening workpiece can be take top 10 tip as the activity of axle deflection.This axle deflection is flexibly connected in the scope that is generally rotated in 0-15 °, can meet workpiece end face out-of-flatness and realize co-axially fixed problem, realizes the outer circular shaft-type parts of clamped one time complexity, good stability.
