[Detailed description of the invention]

BACKGROUND OF THE INVENTION 1. Field of the Invention This invention relates to processing equipment for surface finishing parts such as turbine vanes. In particular, the present invention relates to performing processes such as assembly lines where parts are moved from one location to another and work is required to be performed on the parts. Although this apparatus is put to practical use in manufacturing components of gas turbine engines, it can also be applied to manufacturing components in other fields.

0002

BACKGROUND OF THE INVENTION Cast turbine vanes are an example of a component that requires surface finishing. Such parts are usually finished by a vibrating environment.

[0003] The environment in which parts are vibrated to perform finishing generally consists of castings, tubs, and conveying volumes. The transport capacity is large and eliminates the possibility of parts touching each other when placed within the media or within the parts themselves. When the tab or casing vibrates, it vibrates the media and circulates the vibrations through the parts. The medium generates a frictional force on the joints of the parts, and when the relative motion between the parts and the medium is coupled, the frictional force acts on the parts disposed in the medium. For casing, the casing body extends vertically. The media and parts are fed into one end and flowed through the casing like water or pebbles flow through a pipe.

0004

This results in increased media height and inaccurate finishes being delivered.

[0005] Part processing that occurs within a tub or casing with other parts has another significant disadvantage. Although the statistical probability that one component will collide with an adjacent component is small, it is not impossible. In the case of turbine vane casings (hereinafter referred to with reference to turbine vanes), such contact is particularly problematic since the blades must be of high quality. Small scratches and notches on turbine vanes may not be a problem on other parts, but strict tolerances for cast parts mean that expensive castings can be replaced with scrap metal. I might end up with it.

[0006] Processing parts within tabs has additional disadvantages. Typically, the machine fails after sufficient processing time has elapsed to provide a suitable surface finish to the part. The parts are then transported from the tub to the next location,
During these operations, unintentional contact may occur between the turbine vanes, resulting in scratches or nicks that may result in the turbine vanes being discarded.

[0007]

SUMMARY OF THE INVENTION Accordingly, scientists and engineers working under the direction of the applicant have sought to develop a new vibratory finishing process. According to this, the possibility of the blades coming into contact with each other is eliminated or reduced, and the time and effort required for casting the turbine vanes while the blades are finished and moved to the next location can be reduced.

Also included is a respective medium carrying the part requiring surface finishing and means for advancing the part along this surface and for vibrating the medium on which the part is placed. In a particular embodiment, the surface is the interior of a casing in which the helical vanes are arranged. The casing and vanes vibrate while the vanes rotate to respectively move a carrying capacity for transporting parts along the surface of the casing.

The first feature of the apparatus of the invention is the finishing medium and the transport means for the parts arranged within this medium.

Another feature resides in a conveyor having a surface and spiral vanes for advancing media along a continuous plane from one location to another. A further feature consists in the predetermined conveying volumes spaced along the screw conveyor.

Another feature of this method consists in arranging a predetermined continuous transport volume on the surface and moving this successive transport volume sequentially along the surface. In the example,
A feature of this method is that it prevents the media from moving from one transport volume to an adjacent transport volume.

A first advantage of the present invention is that it transports a limited number of parts in separate transport volumes, so that the parts are not damaged as they move through the vibrator for finishing the parts. This means that you can avoid being exposed to. A further advantage is that each carrying capacity carries only one part, eliminating the possibility of adjacent parts colliding with each other. Another advantage of the present invention is that the degree of finish of the part can be predicted while the part is being transported between two points at a predetermined rate given to the transport capacity, making full use of time and space in the part finishing method. This is possible. This method is particularly effective in assembly line operations or in applications where automatic machines continuously handle parts during the manufacturing process of finished parts. Additional advantages of the present invention include process continuity and predictable finish due to the use of spiral vanes to advance media and parts in the proper direction. In an embodiment, the effectiveness of this device is such that the medium exerts a frictional force on the surface of the helical vane and advances to cause the helical vane to rotate about its axis, thereby increasing the effectiveness of this device in climbing up the wall in the same direction of rotation as the vane. It is further enhanced by the medium. A further advantage is that the flap-type elastic seal arranged between the helical vane and the elastic surface of the casing is long-lasting and replaceable.

The above-described features and advantages of the invention will become more apparent from the following detailed description of the most preferred mode of carrying out the invention and from the accompanying drawings.

[0018]

DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 shows one embodiment of the present invention in which a conveyor-type apparatus 10 is employed to apply finishes to multiple parts, such as in the production of multiple castings for turbine vanes 12. ing. The device has a base 14, a first end 16 in a first position, and a second end 18 in a second position.

Screw conveyor 22 extends between first end 16 and second end 18. A plurality of springs 24 are provided extending between the base 14 and the screw conveyor to provide flexible support for the screw conveyor.

A vibrating screen 26 and a chute 28 are provided to receive the finishing media and turbine vanes from the screw conveyor and to separate the vanes from the media. This screen and chute are located at the second end 18 of the screw conveyor.
Flow to and contact.

A belt conveyor is provided extending from the chute to the first end of the screw conveyor for returning the finishing media to the first end of the apparatus for reuse in the next transport volume.

Means are provided for supplying a predetermined transport volume to the screw conveyor and for receiving media from the belt conveyor. One example is a suction hopper attached to the first end of the casing. This suction hopper has a predetermined volume. When finishing media fills this hopper, a level sensor (not shown) determines when the media height reaches a predetermined height. Finished parts, such as turbine vanes, are automatically dropped (by a robot, not shown) and a hopper opens to transport the media and turbine vanes into the first end 16 of the screw conveyor. Spit it out.

A pipe 36 is provided for supplying fluid to the screw conveyor 22 at a separate location. This pipe connects to a source of water-like finishing agent or finishing solvent to thin the finish. This means supplies fluid to the screw conveyor and has a plurality of outlets 38 for supplying fluid to the screw conveyor at a predetermined rate (usually in trickles).

The screw conveyor has an auger 42 with an axially extending shaft 44. The casing 45 is arranged around this axis. The casing is attached to a spring 24. The shaft has an axis of rotation Ar.

[0025] The casing 45 extends vertically. The casing includes a first sidewall 46 and a second sidewall 4 laterally spaced from the first sidewall leaving an opening or cavity 52 therebetween.
It has 8. A first end member 54 and a second end member 56 extend laterally between the sidewalls for rotatably engaging the axially extending shaft 44. The casing has an inner surface 58 formed by a coating of elastic material. This resilient material also coats the auger to provide a resilient surface 62 to the auger. As an example of the perfect materials, Ultramatic Equipment Company (848 Westgate Drive, Addison, IL)
There are more urethane coatings available. This allows for coating during the manufacture of the casing. This urethane coating has a durometer rating of 90.
It is.

The bottom section 64 extends circumferentially from the first side wall 46 to the second side wall 48 about the axis Ar. This bottom section has a circular arc of 180 degrees or less and a cylindrical shape. The side walls and the bottom section may be made of one piece of material, or the side walls and the bottom section may be joined in such a way that they complement each other. The bottom section and side walls form an open-through casing for receiving a predetermined amount of media 30 and turbine vanes 12 and supporting the media 30 and turbine vanes as the media travels through the screw conveyor carrying the turbine vanes. .

The auger 42 rotatably engages the end section of the casing. The auger has a helical vane 66 that complements the shaft 44. That is, it is usually a spiral type or a spiral type, and may be a spiral type in which the height and space between the tops T1, T2, etc. vary. The spiral blade has a plurality of tops T1,
Extending axially through the casing with T2, T3, T4, T5. The spiral groove extends between the tops of the vanes. As shown in connection with FIG. 2, the bottom part 68 of the vane, which is combined with the bottom part of the casing,
Form multiple chambers as shown in .

A resilient seal component 72 extends from the helical vane 66 to the inner surface 58 of the casing at least beyond the arcuate portion of the casing. The seal has a plurality of individual seal members 74.

Means 76 rotates auger 42 at a predetermined speed.
Provided for rotating. It is located at the first end 16 of the conveyor-type device 10 and is attached for propulsion to the auger shaft 44 . The auger rotation means may include, for example, a meshing gear 78 and a chain 82 engaging the meshing gear, and a chain drive means such as a motor (not shown). Two universal joints (not shown) are attached to the mating gear shaft and the auger shaft. This universal joint accommodates misalignment of the two shafts during the oscillating motion of the screw conveyor. This means also acts as a brake necessary to control the speed of the auger.

FIG. 2 is a cross-sectional view taken along line 2 to 2 of FIG. 1, with the structure exploded to clearly show the relationship between the bottom 68 of the helical vane 66 and the bottom 86 of the casing. It is a part of. As shown in FIGS. 1 and 2, the spiral vane has a plurality of tops T1, T2, T3, T
4, T5 and a spiral groove 67 extending between the top of the vane. each top and the next two adjacent tops (
For example, at the bottom 68 of the vane between T1, T2, T3) the vane forms two ends 68a and 68b that extend at an angle into chamber ch1. Each chamber is adapted to a screw conveyor located within the chamber and capable of receiving a predetermined amount of finishing media 30 therein. The sides of the chamber are closed off by a bottom 86 of the casing 45 adjoining the chamber extending between the ends of the chamber. In this way, the bottom portion 68b of the blade between the top portions T2 and T3, and further 68c between the pair of adjacent top portions T3 and T4, are connected to the adjacent chamber ch2.
limit.

The helical vane and casing thus define a plurality of compartments at the bottom of the casing and at the bottom of the vane.

Resilient sealing component 72 typically extends radially from helical vane 66 to vane 66 and inner surface 58 of the casing.
and engages the bottom of the casing 45.

FIG. 3 is a cross-sectional view taken generally along line 3 to 3 in FIG. A portion of helical vane 66 is also shown exploded to show its relationship to 45.

As shown in FIG. 3, a resilient seal component 72 extends between the vane and the casing. The blade is a rotating member having an axis of rotation Ar. Although the casing is a non-rotating member, it is possible to move with the vanes due to the different inertial loads on the casing and the auger.

The casing has a sealing area 88 spaced radially from the vanes and defining a gap G. The gap G can be removed during the working state of the machine, e.g. by the auger 4.
This may vary depending on whether the vibration of No. 2 is in the same phase as the vibration of the casing 45 or not.

The vane has a rim region 92 . The seal component includes a plurality of seal members 7 extending radially outward from the blade.
It has 4. The sealing members each consist of a resilient material that slidably engages the sealing area of the casing. Each sealing member is elastically deflected in the radial direction from the direction of rotation towards the rim of the vane. This distortion is
Gap G, which is a rift less than the protruding length of the sealing member
is proportional to.

A meshing gear 78 is provided for applying vibratory motion to the casing. This vibration means is attached to the casing 45. An example of such means is a weight 98 spaced radially from the axis of rotation.
There is a rotating shaft with unstable vibrations applied from the shaft. This shaft is rotatably supported.

A first arm 100 and a second arm 102 extend laterally from the casing.

Preferably, this instability causes an oscillating movement of the casing up and down in the vertical direction. This vibrational movement is transmitted from the casing to the medium, which moves together with the parts placed within the medium and the casing.

As shown in FIG. 3, the media 30 generates a circulation pattern that varies depending on the amount of media in the chamber, making the media functional and occupying the active area of the device. The amount of media defined in region R1 forms a circulation pattern C1 of a given period for a given type of media and vibration amplitude.
has. Since the media in region R1 is not deposited as high, it engages the shaft of the auger.

[0041] If a slightly larger amount of medium is added to the room,
The medium assumes the posture shown in region R2. Thus, region R2 is the region R1 plus an additional amount of media. The medium in region R2 engages the lower half of the rotating shaft. Experience has shown that the media in region R1 is located below the axis, the media in region R2 does not exceed the upper half of the axis, and that these regions have a circulation pattern as indicated by arrow Z1. Increasingly, a second circulation zone Z2 as indicated by arrow Z2 can be established (
and can almost certainly be pulled up on the axis)
. It is contemplated that components placed within the media may be moved from the first circulation zone to any second circulation zone on top of the media.

b, 68c.

FIG. 4 also shows the rim region 92 of the vane, which shows the relationship of the components forming one embodiment of the resilient sealing element 74. The vane rim region 92 has a plurality of holes, designated as holes 104 and bolts 106, for receiving nut and bolt components in each hole. Seal transport member 108 with a plurality of axial slots
is attached to this rim.

A plurality of seal members 74 extend radially outwardly from the vane with one seal member in each slot, three of which are shown. Each seal member has a root 114 that engages the seal member with the vane slot. Each sealing member has a sealing flap 116 made of resilient material. This extends radially outward from the root and allows the sealing member to slide into the sealing area 88 of the casing.

Omit 8. Side plate 118 and seal transport member 108 axially capture the seal member.

As can be realized, the rim area of the vane is
A single-sheet structure with multiple slots may be used without requiring seal conveyance. This seal member can be easily replaced by loosening the side plate, allowing the spacing between the seal members to be changed and worn or damaged seal members to be replaced.

FIG. 6 shows one seal member 7 shown in FIG.
4 is an enlarged view of FIG. Seal flap 1 of seal member 74
16 has a width W in the outer circumferential direction. A height H of about 9 inches is more than 6 times the width W, and a height H approximately 10 times the width W is a satisfactory structure. The sealing flap has an axial length L that is at least three times this width, and four times this width is a satisfactory construction. The root width Wr is the flap width W
larger than In a perfect example, auger 4
2 and casing 45 were covered with an elastic coating, which was made of urethane available from Ultramatic Equipment Company, which sells durometers rated up to 90. The flap material was manufactured by Avex Rubber Products Corporation (Portland, Conn.).
It was made of urethane elastomer material available from 100 Indian Hill Avenue, and the design number was urethane material A-6040-R. Preferably, the hardness of the urethane flap is less than the hardness of the vibrating casing and the urethane liner of the auger to minimize wear on the auger and liner surfaces.

In one embodiment, the diameter of the auger about the axis of the shaft in the rest position was approximately 19 inches. A three-quarter inch gap G was provided between the vane rim region 92 and the casing surface at the circular cross section of the bottom of the casing. The expected vibrations were considerable, plus or minus a quarter inch in the vertical direction. Therefore, the practically effective clearance between the vane and the resilient surface of the casing was from 1/4 inch to 1 1/4 inch. The length of the flap extending from the vane surface was 1 and 1/4 inches. The distance between adjacent flaps Sg at the outer periphery was 1/4 inch.

FIG. 7 is an end view taken generally along line 7 to 7 of FIG.
0 is partially omitted. As shown in FIG. 7, the auger rotor rotates about its axis at a rate of approximately one revolution every 3 to 5 minutes (.2 to .33 rpm). at the same time,
The rotor shaft 96 and its eccentric weight 98 rotate about its axis applying approximately one quarter inch of vertical motion, as shown by the dotted line in FIG. It is emphasized.

FIG. 8 shows the effect of relative oscillatory movement of the helical vane 66 with the casing inner surface 58. The vane has a rest position B0 and the casing surface has a rest position C0. In this rest position, the sealing member is elastically biased as shown in full.

During the vibration of plus or minus Va from the rest position, and when the auger vibrates at a frequency that is 180 degrees out of phase with the casing, the casing deflects radially downward to position Cb, and the blades radially deflect. upward position B
Deflect to u. When the casing and vanes are in their respective positions, the seal member extends radially outwardly to its maximum length and contacts the casing surface as indicated by the seal member outlined in dotted lines. Therefore, the sealing member can provide sealing even when the gap G is at its maximum. If this vibration is made in exactly the same phase,
The vane moves to position Bd and the casing moves to position Cu, creating a minimum gap G between them. At this position,
The sealing member is further deflected from the not shown seal rest position, as shown in the phantom image. Although there is a circumferential gap Sg between the blades, the axially rigid sealing flap prevents the medium or the blades from entering the variable gap G between the blades and the casing.

If a plurality of parts are to be processed, a predetermined amount of the carrier medium 30 located on the inner surface of the casing 58 is arranged continuously. Each medium is adapted to carry at least one turbine vane in the finishing medium. The inner surface of the casing is the surface that supports the media and the turbine vanes that it carries. The finishing media, by virtue of its contour, provides the necessary surface finish to the part, i.e., edge and surface finish. A perfect turbine vane medium is
It consists of a silicon carbide material in the shape of a rounded triangle with a 60 degree surface contour, available from U-M Abrasives, Inc. (PMC-3186-1, Kennedale, Texas). Preferably, the rotor blades are arranged in each successive conveying medium in order to convey the rotor blades at a predetermined distance to turbine vanes in adjacent conveying volumes.

As the auger 42 rotates, the elastic surface 62 of the helical vane 66 is an inclined surface that exerts an axial force on the medium and causes the medium to travel in a predetermined path along the elastic inner surface 58 of the casing 55. It acts as. Each conveying volume is captured within its chamber channel by a helical vane and a resilient sealing element 72 extending between the vane and the inner surface of the casing.

[0054] When a vibratory motion is applied to the casing 45 and from there to the medium 30, the medium moves along with the casing and the turbine vanes. Due to this oscillatory movement, the medium can follow a circulation zone Z1 for the conveying volume lying in the regions R1, R2. Turbine vane 12, initially located on top of the medium in hopper 34, moves into the medium following the circulation of zone Z1. The amount of work done on a turbine vane is proportional to the pressure exerted by the medium and the height (or head) of the medium above the turbine vane. Maximum work is done on the turbine vane when it reaches the bottom of the circulation zone Z1 in region R1. As the turbine vanes rise toward the top of the circulation zone, the work output decreases because the height of the media (and the weight of the media on the turbine vanes) decreases. The medium and the turbine vanes thus circulate downwards towards the bottom of region R1 where the maximum work is done to the turbine vanes.

The amount of work done on a surface is proportional to the frictional force acting on the surface. Frictional force is proportional to pressure. Therefore, a sharp blade with a small area will quickly shatter it, but a large area will only scrape the material a little.

If the chamber is filled with a transport volume that lies within region R3, the chamber will overflow and a recirculation zone as indicated by arrow Z2 will almost certainly be created. It has been found that the secondary recirculation zone may trap the turbine vane when it rises to the top of the recirculation zone Z1. After the turbine vane moves to the secondary circulation zone Z2, the turbine vane remains in the secondary circulation zone Z2 and is hardly processed due to the significantly low height of the secondary circulation zone. The surface finish on the vanes within the secondary circulation zone will be unsatisfactory.

The fluid flows into each chamber ch and drains through the medium into each chamber. The fluid carries the finishing agent, and the finishing agent acts as a soap to cleanse the finishing medium. The fluid carries fine fragments of the finishing media as a result of media wear and cast iron and debris from the turbine vanes. Once the fluid is drained to the bottom of the chamber, it flows axially by the auger. It is also possible for fluid to flow between the seal members in the gap Sg near the root of the seal element, providing a secondary path for removing such waste from the processing device.

A particular advantage of the present invention is that each turbine vane is independent from the adjacent turbine vane by the bottom side of the helical vane and the sealing member, by the inner surface of the casing. In this way, each turbine vane is processed individually even if multiple turbine vanes pass through the finishing device.

Another advantage of this process is that the turbine vane can be transported between two points in a flow operation when the turbine vane is finished with a predetermined amount of transport medium. Therefore, efficient work is possible, and this finishing process can be used as a blade conveying process, and when the turbine vane is moved by automatic flow work, the conveying process can be used as a finishing process for the turbine vane.

[0060] As can be seen, this method of finishing conveying multiple turbine vanes in series is capable of automated feeding and removal, such as is found in automated line operations for manufacturing turbine vanes and other parts. Particularly suitable for work.

A further advantage of this process is the quality of the finish produced on each turbine vane. This quality can be achieved if adjacent turbine vanes are not isolated from each other.
This benefit comes from avoiding the turbine vanes colliding with each other as would occur during operation. Furthermore, quality can be increased by keeping the height of the media at a constant amount, and quality is obtained from finishing the vane with a predetermined amount of media. The vanes are isolated without compromising process efficiency, and the first turbine vane group is removed from the finishing media, eliminating the need for machine removal or downtime when placing a new turbine vane group in the media.

Although the invention has been described with reference to detailed embodiments thereof, those skilled in the art will appreciate that various changes in form and detail may be made therein without departing from the scope and spirit of the claimed invention. It should be understood by those who have the following.

[0063]

[Effects of the Invention] As described above, according to the present invention, since a limited number of parts are transported in each separate transport capacity,
Damage to the parts can be avoided when the parts are moved through the vibrating device for finishing the parts. Furthermore, since only one component is transported with each transport capacity, the possibility of adjacent components colliding with each other can be eliminated. Furthermore, according to the present invention, the degree of finish of the parts can be predicted while the parts are being transported between two points at a predetermined rate given to the transport capacity, so that sufficient time and space are available for the part finishing method. can be utilized. Furthermore, the method of the present invention is particularly useful in assembly line applications and in applications where automatic machines continuously handle parts in the manufacturing process of finished parts. The present invention further provides process continuity and predictability of finish due to the use of spiral vanes to advance media and parts in the proper direction.
