WE FidE FRANK H. ERNSEE AND RALPH B. VESSEY, (DE FLINT, MICHIGAN, ASSIGNORS TO A C SPARK PLUG COMPANY, OF FLINT, MICHIGAN, A CORPORATION OF MICHIGAN.
ATTACHMENT FOR AUTOMATIC TUB/BET T-IIACHINES.
Application filed December '4, 1919. Serial No. 342,430.
T 0 (ZZZ whom it may concern:
Be it known'that we, FRANK H. ERNSER and RALPH B. Vnssnr, citizens of the United States, and residents of Flint, county of Genesee, and State of Michigan, have invented certain new and useful Improvements in Attachments for Automatic Turret Machines, of which the following is a full, clear, concise, and exact description, such as will enable others skilled in the art to which the invention relates to make and use the same, reference being made therein to the accom an in drawin s which form a art of this specification.
The invention relates to an attachment for automatic turret machines of the multiple spindle type and has for its object an increase of the usefulness of machines of this type by rendering them capable of performing certain operations for which they are otherwise not adapted.
The invention comprises broadly a tool holding means which may be mounted upon the main tool slide of the machine and which is adapted to have a forward and backward movement independent of that of the said tool slide. It further comprises various details of construction designed to carry into effect the object of our invention, all as hereinafter more fully set forth.
I11 the accompanying drawings forming a part of this specification, Fig. 1 is an elevation showing one embodiment of our invention, certain parts being shown in section; Fig. 2 is an end view of the structure shown in Fig. 1, the view being taken on line acc of Fig. 1; and Fig. 3 is a detail view showing a portion of the operating means for the tool holder.
In the drawings 1 indicates a spindle-car-- rying cylinder, and 2 the chucks which are designed to be rotated by spindles mounted within the cylinder, as is common in machines of this type. The cylinder is pro,- vided with an extension 3 on which is slidably mounted a main tool slide l. Tool supports or holders 5 may be mounted in slots 6 of this slide, the drawing showing four such slots adapted to carry tools to co-operate with a corresponding number of spindles. The tool slide 4 is provided with a head 7 which may carry means cooperating with a slide bearing, as usual in machines of this character, in order to permit sliding movement but prevent rotative movement.
In a projecting portion 8, integral with or suitably secured to the head of the slide, is formed an aperture to receive a bushing 9 prevented from turning by suitable means, as pins 10. The bushing carries keys 11, secured as by rivets 12, and adapted to engage in grooves 13 of slide 14-. To the rear end of slide i l is secured by bolt 15, a roller 16, adapted to engage cam 17 on cam drum 18. This cam as will be seen from Fig. 1, is adapted to cause movement of the slide 14 and related parts to the right. A positive return movement is obtained, by mounting on the cam drum an additional cam 19.
The forward end of slide leis tapped to accommodate the threaded end of connecting member 20, which may be secured in adjusted position, as by lock nut 21. The squared head of member 20 is provided, as shown, with a slot 30, within which is seated a head 22 on a corresponding connecting member 23. This head and slot connection is made with a loose fit so as to permit a very slight play, but prevent any material relative angular movement of the parts.
As indicated on the drawing the shanks of members 20 and 23 are oppositely threaded, so that, by engagement of a wrench on the squarel heads of said members, any desired adjustment of the length of the tool holding device as a whole, or of the advance of the tool, may be obtained.
Merely as an illustration of the operation of our invention it may be assumed that the tool 29 is a reamer designed to perform a final shaping operation upon stock which has already been operated upon by tools cooperating with various spindles of the machine It will also be assumed that the travel of the reamer relative to the stock is less than that desired for the other tools carried by the tool slide. It will be seen that the structure described provides for a forward movement of the reamer and for its return independently of the movements of the main tool slide, whereby the advance of the reamer may be limited to the desired amount without in any way interfering with the travel of the other tools.
It will be understood that any other type of tool may be similarly employed wherever it is desirable that either the extent, duration, or timing of the movement of one tool should vary in relation to that of the others. It will also be understood that, since the movements of tool and work are merely relative, our invention is equally applicable whether it be the work or the tool that is supported on the slide. Various modifications may also be made in the details of construction without departing from the spirit of the invention, and we therefore do not wish to be limited to the specific construction herein described.
We claim:
1. The combination with a main tool slide of an auxiliary tool slide mounted thereon, means for prelin'iinary adjustment of the auxiliary slide on the main slide, and cam means for cruising relative movement between said slides.
2. The combination with a main tool slide of an auxiliary tool slide mounted thereon for movement in the same direction as said main slide, and cam means for causing both forward and reverse movement of said auxiliary slide relatively to said main slide, said auxiliary slide including means for preliminary adjustment of its tool holding position with reference to said main slide.
3. The combination with a main tool slide of an auxiliary tool slide mounted thereon for movement in the same direction as said main slide, and cam means for causing both forward and reverse movement of said auxiliary slide relatively to said main slide, said auxiliary slide comprising two slidably supported members and screw means connecting said members to provide adjustment.
In a tool holder the combination of two relatively movable elements, and screw means cormecting said elements to provide for adjustment, said screw means comprising oppositely threaded members joined to each other by loosely fitting connections to permit a slight amount of play between said members.
5. The combination of a main tool slide havingslots on the exterior thereof to receive tool holders, a holder associated with one of said slots, a slide bearing in said holder, an auxiliary tool slide mounted in said bearing, and means for operating said auxiliary slide to cause a tool supported thereby to advance or recede relatively to said main slide.
In testimony whereof we afiix our signatures.
FRANK H.- ERNSER. RALPH B. VESSEY.
