This invention relates to a magnetic angle plate for use on magnetic chucks on grinding machines for holding the work to be ground so that the latter may be supported, without clamping, at
any desired angle.
The invention together with its objects and advantages will be best understood from a study of the following description taken in connection with the accompanying drawings wherein:
Figure 1 is a plan view of a fixture or angle block embodying the features of the present invention;
Figure 2 is a sectional view taken substantially on the line 2-4 of Figure 1;
Figure 3 is an elevational view of a gauge plate forming part of the invention and viewing the same from the grooved side thereof;
Figure 4 is a side elevational view of the angle block or fixture;
Figure 5 isa front edge elevational view of the angle block or fixture;
Figure 6 is a fragmentary detail sectional view taken substantially on the line 66 of Figure 4;
Figure 7 is a fragmentary detail view illustrating the application of a stud to the angle block for a purpose hereinafter more fully explained;
Figure 8 is a plan view of an angle block and an attachment therefor embodying the features of the present invention; 30 Figure 9 is a side elevational view of the assembly shown in Figure 8 with the-gauge illustrated in broken line; and
Figure 10 is a detail view showing a threaded stud used in the assemblage of Figures 8 and 9.
Referring to the drawings by reference numer- 3.15, and more particularly to the invention as disclosed in Figures 1 to 7, inclusive, it will be seen that the fixture or angle block embodying the features of the present invention, comprises a lower fixture block 5 which is adapted to rest on the base of the magnetic chuck (not shown), and an upper fixture block indicated by the reference numeral 6.
Each of the blocks 5 and 6 is composed of alternate sections or plates 1 of soft steel and alternate sections or plates 8 of non-magnetic material as aluminum, brass or copper.
The plates of each of the blocks 5 and 6 are securely held together, as shown, by binder rods or rivets 9 also of non-magnetic material.
The fixture blocks 5 and 6 are hingedly connected together through the medium of a bolt l0 equipped at one end with a head ii and provided at its relatively opposite end with a nut i2, and in this connection it will be noted that certain of the plates or sections of the blocks are provided with apertured ears i3 to receive the bolt iii, the ears of the plates or sections of block 6 being positively engaged with the bolt in any suitable manner so that upon rotation of the bolt ID, the plates or sections of the upper fixture block 6 will swing with the bolt as a unit toward or away from the lower fixture block 5 to assume thedesired angle of adjustment.
To facilitate a rotation of the bolt Ill and the associated fixture block 6, the head I I of the bolt has extending therefrom a suitable manipulating handle 24 as shown.
A gauge plate 2| is provided and is disposed against one side of the lower fixture block 5. The gauge plate 2| is provided with an opening 22 which receives the bolt l0 and is also provided with an opening 22a to receive a screw or similar fastening element 22b which is threaded into certain of the plates or sections of the lower fixture block 5 for securing the gauge plate 21 in fixed position relative to the lower fixture block 5.
On the outer face thereof the gauge plate 2| has disposed adjacent its arcuate edge an arcuate series of graduations 23 against which the lower edge of the fixture block 6 is readable for placing the fixture block 6 at the desired angle of adjustment relative to the lower fixture block 5.
Drilled into the upper fixture block 6 are preferably four rows of threaded openings ll adapted to receive bolts l5 for securing at the desired adjustment on the upper fixture block 6 a stop or abutment bar I! provided with slots as shown for receiving the bolts l5, which latter are equipped with washers It as illustrated. It will thus be seen that the work placed on the upper fixture block 6 may be disposed in edge abutting relation with the stop or abutment bar I! to hold the work properly against the tool. It will be apparent that by providing the abutment bar I! with slots, and the upper fixture block 5 with openings H as hereinbefore described and illustrated abutment block I! may be secured at any desired position on the block 6 as required by the nature of the work for the operationto be performed on the work.
For guiding the upper fixture block Ii in its swinging movement toward or away from the lower fixture block 5, said fixture block 6 at one edge thereof has projecting therefrom a pin 26 which works in an arcuate groove 25 provided on the inside face of the gauge plate 2| as shown in Figure 6.
Also, at suitable points thereon the upper fixture block 6 has tapped thereinto relatively spaced transversely aligned openings i8, i8a, the latter opening being threaded to receive a stud bolt Ifla while the former opening i8 is smooth and is adapted to receive a stud pin i9 (see Figures 'l and 10) The threaded stud bolt Ha is secured within its opening I80 through the medium of a set screw or the like 21 (see Figure 9).
Said pin is and said bolt l8a are used when it is desired to apply to the upper fixture block 6, and in lieu of the abutment plate l'i, an assembly shown in Figures 8 and 9 for holding on the angle block work of, for example, the type suggested in Figure 8 by broken line and indicated generally by the reference letter W.
This asseinbly as shown in Figures 8 and 9 consists of a substantially rectangular plate 28 that is adapted to rest partly on the top of the upper fixure block 6 and adjacent one end edge is apertured to receive said pin i9 and stud bolt Isa as shown. The plate 28 is further secured in position through the medium of a nut 29 threaded on to the stud bolt l9a, a washer Iii being provided for disposition between the nut 29 and the plate 28.
Pivoted to the plate 28 forwardly of its transverse center and indicated generally at Si is a work stop or abutment plate or arm 32 against which one edge of the work resting on the plate 28 abuts as shown in Figure 8 in a manner to hold the work W in proper position on the plate 28.
For securing the abutment arm or plate 32 at the desired angular adjustment, there is provided on the arm 32 a threaded pin 33 that works in an arcuate slot 34 provided adjacent the forward edge of the plate 28 and equipped with a nut 35 which when threaded against the under side of the plate 28 will serve to secure the abutment arm 32 at the desired adjustment.
Disposed adjacent an edge of the slot 24 is an arcuate scale 36 against which one edge of the arm 32 is readable to facilitate the placing of the arm or abutment plate 32 at the desired adjustment.
It is thought that a clear understanding of the construction, utility and advantages of the invention of this character will be had by those skilled in the art without a more detailed description.
Having thus described the invention, what is claimed here is:
1. An angle block for use with magnetic chucks comprising a lower fixture block and an upper fixture block, said blocks being pivotally connected together at one edge, and each of said blocks being composed of alternate and complementary magnetic and non-magnetic plates, said upper fixture block being provided with a plurality of transverse rows of relatively spaced openings, an abutment block adapted to rest on the upper fixture block, and screw means engaging in slots in said abutment block and in gaging in the openings in said plate and in the upper fixture block for securing the plate to the upper fixture block, a work abutment arm pivoted to said plate, and means for securing said work abutment arm at the desired adjustment on said plate.
2. An angle block ior use with magnetic chucks comprising a lower fixture block and an upper fixture block, said blocks being pivotally connected together at one edge, and each of said blocks being composed of alternate and complementary magnetic and non-magnetic plates, said upper fixture block having a plurality of spaced transverse rows of relatively spaced openings therein, an abutment block adapted to rest on the upper fixture block, screw means engaging in slots in said abutment block and in selected openings in the upper fixture block for securing the abutment block at the desired adjustment, said upper fixture block being also provided with an additional pair of relatively spaced openings. a plate adapted to rest on the upper fixture block and having openings aligning with the last-mentioned openings, stud elements engaging in the openings in said plate and in the upper fixture block for securing the plate to the upper fixture block, a work abutment arm pivoted to said plate,
