Kalamazoo, Mich.
Application March 15, 1951, Serial No. 215,664
11 Claims.
- This invention relates to improvements in a method of deburring and finishing.
The main objects of this invention are:
First, to provide a method of finishing which is well adapted for the deburring and finishing of various materials of various sizes and shapes and which enables the economical finishing thereof in a highly satisfactory manner.
Second, to provide a method of deburring and finishing metal parts of irregular shape in a satisfactory manner.
Third, to provide a method of finishing parts with aggregates such as have been employed in tumbling barrels and one in which the parts treated are not dented or injured by impact of one part with another.
Fourth, to provide a method of finishing parts which may be very economically practiced.
Objects relating to details and economies of the invention will appear from the description to follow. The invention is pointed out in the claims.
In the accompanying drawing we have illustrated a satisfactory apparatus for the commercial practice of our invention, certain parts of the apparatus being illustrated conventionally.
Fig. 1 is a side elevational view with parts broken away to more clearly disclose the structure.
Fig. 2 is a fragmentary view in section on a line corresponding to line 2-2 of Fig. 1.
The apparatus illustrated comprises a base i having a transmission housing 2 mounted thereon. An electric motor 3 is mounted at one end of the housing 2. A cylindrical tank t is mounted on the housing and is open at the top and adapted to receive the deburring and/or polishing material designated generally by the numeral 5. Work or parts to be finished are designated by the numeral 6 which in this instance are handles for automobile doors. It will be understood that in commercial practice a very great variety of parts are or may be treated. The tank 4 is open at the top to permit the carrier or work holder designated generally by the numeral 1 to be moved vertically to raise and lower the carrier to submerge the work in and lift it from the mass 5.
The annular carrier or support 8 having depending arms 9 is provided with work chucks convenitionally illustrated at ill for the parts or work 6. The carrier 8 is provided with a hub I2 which is of noncircular section and slidably engages the noncircular portion 53 of the driven rockshaft l which is connected by the sprocket chain it and gears I! to the shaft $8 of the motor. jThese driving connections are such as to operate the carrier with an oscillating or reciprocating movement.
The carrier 8 is raised and lowered to submerge the work in the finishing aggregate 5 by means or" the tackle 19 connected to the carrier through the fleixble hanger 26. The polishing material 5 is conventionally shown but may desirably be a mass of fractured mineral fragments of irregular sizes and shapes. Fractured stone fragments ranging in long dimension from 1 to 2 produce satisfactory results. The abrasive fragments are submerged in a liquid having suitable lubricating and cleaning qualities.
The work parts 6 are mounted on the carrier arms 9 in groups, the parts of the groups being vertically aligned and mounted on the chucks in relatively fixed relation. The arms 9 or the carrier are angularly spaced and are fixed relative to each other. With the mass of aggregate fragments submerged in the liquid, the carrier with the work mounted thereon is lowered to submerge the work in the mass as is shown in the drawings and the carrier oscillated. The length of the oscillatin or reciprocating strokewhile substantial is shorter than or less than will in-, duce a substantial flow of the mass in the direction of travel of the parts as they are translated through the mass. This results in a maximum abrasive or finishing action of the finishing material on the work as the work is translated through the finishing material instead of the work and finishing material traveling together.
As the work is continuously submerged while being translated or moved relative to the finishing mass, the parts are very rapidly finished. It will be understood that the time factor depends on the character of. the finish desired and the character of the Work, that is, whether it is relatively hard or relatively soft and the character of the finishing material affects the time factor; however, the applicants method is advantageous from these standpoints or from all of these factors.
Another advantage is that if it is desired to inspect the work, it may be lifted from the aggregate and when thus mounted, the parts may be inspected. If further finishing is required, the work may be lowered into the mass.
We have illustrated and described a satisfactory apparatus for the practice of my method. We have not illustrated or described other apparatus as it is believed that this disclosure will enable those skilled in the art to successfully practice our method as particular conditions may require.
