3 Claims.
This invention relates to an improved workholding and drivingchuck for lathes or like machines, and the primary object of the invention is to provide 'a device of this kind which is capable of holding work regardless of whether it be concentric or eccentric.
Another object of the invention is to provide a chuck of the above kind which is especially designed to hold work that has a thin wall and cannot be handled in an ordinary chuck.
A more specific object of the present invention is to provide a chuck of the above kind which is comparatively simple in construction, and which provides for a number of adjustments in a simple and expeditious manner whereby work of various kinds may be readily and quickly clamped in place for performing operations there- The present invention consists in the novel form, combination and arrangement of parts hereinafter more fully described, shown in the accompanying drawings and claimed.
In the drawings, wherein like reference characters indicate corresponding parts throughout the several views:
Figure l is afront elevational view showing the face plate of the head stock of a lathe or like machine equipped with clamping devices constructed in accordance with the present in- Vention.
Figure 2 is an enlarged side elevational view of one of the clamping devices shown in Figure 1.
Figure 3 is an enlarged fragmentary sectional view taken on line 33 of Figure 1.
Figure 4 is a view looking upwardly at Figure 2.
Figure 5 is a fragmentary section taken on line 5-5 of Figure 2.
Figure 6 is an enlarged perspective view of the work-engaging jaw forming part of the device shown in Figure 2.
Figure 7 is a perspective View of a modified form of attaching base for the clamping device, and
Figure 8 is a perspective View of the inner member of the attaching base forming part of grooves 6 of face plate 5. Each clamping device includes an attaching base composed of an inner elongated block E provided at its outer'side with a longitudinal rib 8 and formed with a longitudinal slot 9. In the embodiment of Figures 1 to 6,
inclusive, and 8, the attaching base further includes an outer elongated plate member ID having a longitudinal groove H in its inner face adapted to snugly slidably receive the rib 8 of base block 7. The outer member It also has a transverse opening 82, and an attaching bolt 13 members I and I0 may be radially adjusted relative to each other in either direction. The device further includes a U-shaped frame rigidly attached to one end of base member H1 and projetting outwardly therefrom, the free ends of the legs of frame it straddling the end of base member It] and being fastened thereto by means of screws I! or the like. journaled at one end in a socket l9 provided in the base member l0, and near its other or outer end in an opening 2a provided in the outer intermediate portion of frame member It. This outer end of screw it has a polygonal extension 21 so that it may be engaged and rotated by means of a suitable tool or Wrench. The legs of frame member l6 are formed on the inner sides thereof with longitudinal ribs 22, and slidably fitted in the frame [6 is a slide block 23 having side grooves receiving the ribs 22, as at 24. The slide block 23 is provided with transverse openings at opposite sides of screw it, and slidably engaged in these openings are the legs of a bifurcated clamping member 26 having a projecting workengaging jaw 21 on the inner end thereof. The outer free ends of the legs of member 26 are adjustably connected by a transverse tightening bolt 28 extending through openings 29 in the legs of said clamping member 26. It will thus be seen that by rotating screw is, the block 23 may be adjusted toward or away from the face plate 5, and by loosening screw 28, the clamping member 26 may be adjusted inwardly or outwardly radially of said face plate 5. A simple and durable construction is thus had for effectively and expeditiously carrying out the stated objects of the invention. 7
An adjusting screw I8 is.
A modified form of attaching base is shown in Figure '7 which may be substituted for the base composed of members 1 and I0. As shown, this modified form of attaching base includes an angular member having a base portion Illa provided in its inner face with a longitudinal groove Ha adapted to receive the rib of a base member corresponding to base member I or constituting the latter. This base portion lUa has a, transverse opening lZa to receive the bolt [3, and an arm 30 projects outwardly from one end of base member Illa and is provided in the sides of its outer end portion with grooves 3| adapted to receive the ribs 22 of the frame member 16 when attached thereto by screws similar to screws I! engaging in threaded sockets 32 of said arm 30. In this embodiment, the outer end of arm 30 will of course have a socket 33 to receive the inner end of adjusting screw l8, similar to the manner in which said end is received in socket 19 of base member 10. By using this elementv of Figure 7, the device may be adapted for forholding work that extends a greater disbeing journaled in the outer base member and the outer end of said frame, means at the outer end of said adjusting screw to facilitate manual rotation thereof, the legs of said frame member having longitudinal ribs on the inner sides thereof, a slide block arranged in said frame and having grooves slidable receiving sair last-named ribs, said slide block having a threaded opening receiving the adjusting screw and being provided with transverse openings at opposite sides of said adjusting screw, and a work-engaging member bifurcated at one end to provide a pair of legs and provided at the other end with a workengaging jaw, the legs of said clamping member slidably extending through the openings of said slide block, whereby the clamping memberrmay be adjusted transversely of said frame member,
tance from the face plate 5 than could be engaged by the jaw 21 when employing the base member l0. 7
From the foregoing description, it is believed that the construction and operation, as well as the advantages of the present invention, will be readily understood and appreciated by those skilled in the art. In operation, the work is clamped against the face plate 5 by means of the clamping devices, to hold and drive the work during the operations thereon.
What I claim as new is:
1. In a chuck of the character described, a clamping device comprising an attaching base, said attaching base embodying an inner block member having a longitudinal rib on its'outer side and provided with an elongated slot therethrough parallel with said rib, an outer base member having a longitudinal groove in its inner face snugly receiving said rib and provided with a transverse opening, a securing bolt passing through said opening and said slot and having a head engageable in the radial undercut groove of a face plate, a U-shaped frame having the free ends of its legs straddling an end of the outer base member and fixed thereto, an adjusting screw arranged within and extending longitudinally of said frame member, said screw and a tightening screw connecting the free ends of the legs of said clamping member.
2. In a chuck of the character described, a clamping device embodying an attaching base, said base including inner and outer members slidably interlocked for relative radial adjustment with respect to a face plate, the inner member having a longitudinal slot, a securing bolt passing through said base members and having a head engageable in an undercut radial groove of the face plate, a slide frame rigid with and projecting outwardly from the outer base member, a slide block in said frame, an adjusting screw for adjusting the slide block in said frame, and a clamping member adjustable transversely of the slide block and having a work-engaging jaw.
3. In a chuck of the character described, a clamping device embodying an attaching base,
said base including inner and outer members slidably interlocked for relative radial adjustment with respect to a face plate, the inner member having a longitudinal slot, a securing bolt passing through said base members and having a head engageable in an undercut radial groove of the face plate, a slide frame rigid with and'projecting outwardly from the outer base member, a slide block in said frame, an adjusting screw for adjusting the slide block in said frame, and a clampingmember adjustable transversely of the slide block and having a work-engaging jaw, said outer base member having an outwardly extending arm to which the frame member is fixed. 7
