Device and method for surface treatment

The priority dated January 29, 1971 of the patent application in Canada S.N. 103 996 is being used.

The invention relates to an apparatus and a method for the surface treatment of workpieces in order to to achieve extremely even and even surfaces. In particular, the invention relates to a Lapping machine with at least one lapping zone and a method in which the workpiece is rotatably supported by such Zones automatically by means of clockwise switching movements the machine is moved.

In machine tool technology it is known that lapping machines and lapping operations are not used to remove metal, but to remove the surface for fineness and quality to edit. The lapping process generally includes the use of a loosely granular lubricant mixed with it oil or other lubricant. This mixture is applied to the workpiece, the surface of which is to be treated, by means of a disk or the like. Applied. The lapping eye is generally made of a softer material than the workpiece to be lapped and can be made of soft cast iron.,

Brass, copper, lead or mild steel exist. You will find that the harder the lapping tool, the slower the work process, the worse it gets the surface finish and ofesto faster finds the wear and tear instead of. The surfaces of the lapping tools, namely the lapping disc, are generally serrated to keep the work surface clean and free of dirt or debris buildup keep. U.S. Patent 2,469,563, May 10, 1949, R.K. Kinard, describes such a type of lapping machine. This machine provides an element which is provided with a large number of lapping surfaces and is surrounded by a retaining element,! and which cooperates with a lapping plate to counter-; lapping stands that are on the lapping surface. The lapping plate is stored loosely on the objects to be lapped, namely the workpieces, and swings with the Lapping parts. The previously known lapping machine is adapted so that it enables two parallel surfaces on opposite sides Lapping sides of the workpiece.

With these state-of-the-art lapping machines, problems would arise if, for example, the operator tried to lapping multiple small workpiece surfaces at the same time and at high speed. This conventional Lapping machines that use a disc can only achieve an accuracy of one lightwave bandwidth of flatness. This difficulty occurs often, particularly in connection with uneven wear of the surfaces in contact and due to an accumulation of emery or the like on the machining surface of the lapping disc. From the Kinard-Paterit it can be seen that the retaining element is used to correctly place the workpieces to be lapped on their Hold place. An upper lapping disk is rotatably attached and is reversed alternately by an eccentric attached pin moves. Means are also provided to periodically rotate the upper lapping disc, whereby the Possibility of permanent wear on certain parts

'' the sanded surface of the lapping disc is reduced.
It will be noted, however, that certain difficulties arise because of the significantly large size of the
upper lapping disc and the retaining element for the
lower workpiece, as the machining surfaces are not
are always in a suitable position, that is, they are lying
not always absolutely parallel to each other. Uneven wear
on the fastening surfaces and the bearings, “heat distortion” or the like. Prevent the workpiece j to be machined from being made extremely flat. Furthermore, it will be found in the Kinard patent that even with a j good lapping composition, be it coarse or fine in structure, j cleaning of the machining surfaces on the upper j lapping disc and on the retaining element is necessary, j around the workpiece in several ways To be able to handle stages. ΐ In other words, the lapping machine according to the Kinard patent j is unsuitable, more than one lapping zone in the same machine! to accomplish.

Preferred embodiments of the invention will be described in detail first with reference to Figures 1 and 2 of the drawings explained, in which the invention is shown on a lapping machine, which is designated by 10 throughout. Short In other words, the lapping machine comprises a circular turntable 50 which is supported on a stand-like base 104. One A large number of clamping devices denoted continuously by 150, shown in detail in FIG. 5, are rotatable with Mounted spaced from each other near the outer periphery of the turntable. Each of the clamping devices is suitable Workpieces 152 either by themselves or in workpiece holders. These workpieces 152 are z. B. from one feeding device indicated schematically by the reference numeral 153, which is located at an "input" - or j "Loading" station 2 is located. The workpieces are then moved by a regular switching movement of the turntable through fine sanding or treatment zones, denoted by 1 and 3 in Figure 1, advanced. The workpieces 152 are either by hand or automatically from the clamping devices for removal by an unloading or transfer device 155, which is in the operative position relative to the turntable at an "exit" or "unload" station 4. As previously noted, the loading and unloading of the workpieces 152 is accomplished without the lapping or other finishing operations to stop, which take place in treatment zones 1 and / or 3, lapping machines according to the state of the art had to be stopped or idled during the load-unload operations. In the embodiment shown in Figure 1 are in the treatment zone 1, in which the lapping of the Workpiece 152 takes place, four switching positions of the turntable 50 indicated. Treatment zone 3 contains three of these Switching positions where a second lapping stage, or in the other case, some kind of finish such as polishing can be done. A rest position shown at 6 is between

As shown schematically in Figure 1, each of the treatment zones 1 and 3 has a circular disk conveyor 300 in operative communication with the turntable 50. Each of these circular disk conveyors 300 has a leading end and a trailing end, clockwise with respect to that shown by arrow 51 of the turntable The switching movement of the rotary disk 50 takes place. A disk transfer device 394, which is shown schematically in FIG. 11, is provided at each of the emerging ends. This overrun transfer device causes the transfer of l lapping disks with the reference number 12 from the circulating conveyor j device 300 to the turntable 50. The drain transfer device 394 acts in a corresponding manner, removing lapping disks j 12 from the turntable in good time and placing them on the circulating conveyor 300 . A more detailed description of the two revolving conveyor devices [ and the disk transfer device 394 is continued below in connection with FIGS from the rotary conveyor 300, and will bring such disks 12 into engagement with a disk-carrying head of a disk-bearing and reciprocating device 132, only one of which is shown in plan view at the 8 o'clock position in FIG.

The support housing 56 has upper and lower ends 57 and 59 with inner surfaces that adjoin these ends so as to outer race of a pair of ball bearings 58 and 60 can receive by an interference fit. The inner race of each these bearings 58 and 60 are in turn supported on the outer surface of a rigid column 62 which is attached to a reinforcement plate 64 is welded on. The latter is either with screws or the like on an upper plate 105 of the substructure 104 (Figure 10) attached. The inner ring of the bearing 58 abuts the upwardly extending end of a spacer sleeve 65. The inner Ring of the bearing 60 also abuts against .die spacer sleeve 65 and is held in its position by a retaining ring 61, the is on an upwardly extending shoulder 63 located on the lower part of the fixed column 62 is. It should be noted that such an arrangement enables the turntable 50 to be rotatable about an axis which runs coaxially with the central drive shaft 66 which is arranged inside the fixed column 62.

To ensure that the turntable 50 rotates with periodic motion, the end 59 of the round support housing! 56 is provided with a sprocket 68 which has teeth 69 and which by means of screws or the like at the end of the support housing; is attached. The teeth 69 of the chain wheel 68 engage in a chain 70 (FIG. 10), which is j wheel 72 is driven. The sprocket 72 is by means of a; Keyway and a keyway on the upward j stretching part of the power output shaft 74 of the reduction gear unit 76 attached. This reduction gear 76 is coupled to the main drive motor 78 at a 400: 1 ratio. The connection of the main drive motor 78 with the gear reduction unit 76 is carried out by a pulley assembly 79 and another

alternative arrangements are also possible. From Figure 2 it can be seen that a cover plate 112 by means of screws attached to the end 57 of the support housing 56. This cover plate 112 is provided with a large central opening, so that it can be received close to the tubular column 62. The cover plate 112 is still provided with openings in order to ensure suitable lubrication by means of guide means 113 to the main bearings 58 and 60 to be able to bring about.

The upper part of the solid tubular column 62 is provided with a cylindrical skirt or upper housing 110. This housing 110 is welded to a retaining ring 109, which itself is fixed by means of a screw fastening 111 or the like is attached to the cover 52 of the turntable 50. If necessary, a reinforcement ring 109 can also be provided which is welded to the cover 52.

From Figures 2 and 2A it can be seen that in particular the upper end of the shaft 66 has a stub part 114, and a 2-step reduction in the cross-sectional area. The first stage forms a seat and a shoulder 115 over which the inner ring of the ball bearings 116 is received. The outer ring of the bearing 116 is an interference fit with the inner surface of an adjusting ring 118 which is arranged by means of screws or the like at the upper end of the tubular fixed column. The upper surface of the collar 118 is provided with a shoulder 119 which enables a fixed cam 120 to be attached thereto. As can be seen from the figure, the shape of the fixed cam 120 can be almost elongated, with a double-headed key ring j being provided. The reason for the design of the fixed cam! 120 will be given shortly. The outer part of the j

The inwardly facing surface of this journal bearing 122 is provided with a Shoulder 124 on which a "moving" or powered cam 126 is attached by welding. Since the driven cam 126 is fixedly attached to the shaft 66, the rotational movement of that shaft becomes one cause corresponding rotational movement of the driven cam 126. From Figures 1, 2 and 2A it can be seen that the driven cam 126 is approximately circular in shape and it is eccentric on the journal bearing held. It should also be noted that the maximum radius of the fixed cam 120 is somewhat the maximum Radius of the driven cam 126 exceeds. This property will be described later. The rotation of the driven cam 126 causes due to the interposition of the discs supporting and reciprocating Means 132 a linear reciprocal movement of the lapping disks 12, namely radially to the rotary disk 50, but only within the lapping zones 1 and 3. In these switching positions of the turntable 50 and the lapping zones lying in between 1 and 3, there is no reciprocal movement of the devices 132 or the disks 12. First is one such movement is also not necessary, since these positions are rest positions; secondly, it is also desirable that no to-and-fro movement of the devices 132 between the lapping zones 1 and 3 takes place because an introduction or Removal of the workpieces to the clamping device 150 carried out will. In addition, the workpieces are inspected and / or cleaned before the second stage of the treatment zone 3. It would therefore be very difficult and dangerous to do this

A switching movement of the main turntable 50 causes a relative movement between the rolling device 156 and the fixed cam 120, at least insofar as the rolling device 146 is in one of the switching positions where there is no to-and-fro movement of the lapping disks. As long as the special floating device 132 is in a switching position outside one of the lapping zones 1 or 3, the rolling device located therein comes into play 126 in contact with the periphery of the fixed cam 120. The lapping disc 12 thereon is then moved back and forth accordingly. However, the rolling device 146 is in each of the switching positions within the lapping zones 1 and 3 remain in contact with the periphery of the driven cam 1.26. This fact also follows from of Figure 1. As already indicated, the maximum radial distance of the fixed cam 120 is slightly greater than the maximum radial distance of the driven cam 126. As a result, in these positions outside the lapping zones 1 and FIG. 3 the fixed cam 120 shows the potential effect of the driven cam 126.

The axis around which the main turntable 50 rotates (with periodic Switching position), is coaxial with the shaft 66. The axes of the push rods 136 are generally in one Plane, i.e. 90 ° to the axis of shaft 66. As noted, each lapping disc 12 is floating through the heads 142 is mounted in one of the disk-carrying and reciprocating devices 132 in each case. This floating one Arrangement accordingly allows some degree of pin movement of the lapping disks 12 relative to the heads 142. How can be seen from the left side of Figure 2A, the disc element 16 is loosely connected to the shaft 13 to thereby to be able to achieve a rotary movement. The floating one

The position of the lapping disk 16 is based specifically on this possible rotational movement. Hence there is an absolute parallelism of the shaft 13 with the lapping disks to the axis of the shaft 66 is not essential. Moreover, it is not necessarily required that the surface of the workpieces on different clamping devices 150 exactly in the same plane and perpendicular to the axis of the shaft 66. An uneven alignment can easily be caused by the floating attachment of the lapping disks 12 are compensated.

It is only necessary that in the case of a large number of workpieces to be supported, e.g. in one or in one A pair of workpiece holders 154, as shown in Figures 1, 2 and 2A, that the workpiece surfaces, which are connected to one of the lapping disks 12, are themselves in a common Lie level. That is, the workpiece surfaces that are treated in the 8 o'clock position shown in Figure 1, each must be in a common plane, but not necessary in the same plane in which other workpieces are held on the clamping device in the 9 o'clock position. Every Lapping disc 12-has a disc 16 which is made of hardened steel and is extremely flat on its machining surface. The disk 16 is connected to the shaft 13 by pins, as has already been described. These properties are linked with the floating attachment in each head 142, the lapping disks 12 enable the workpiece surfaces to become one extremely high degree of previously mentioned flatness to be finished.

It has already been noted that the turntable 50 is mounted uniformly at intervals with a series of rotatable clamping devices 150 is provided. These clamping devices preferably work magnetically and serve a workpiece to be held, with or without a workpiece holder in working connection

Device 132 and vice versa to lead. As noted, each shaft 13 on the lapping disks 12 has a pair of diametrically widened parts 14 and 15. These lapping disks need to be moved up and down to either to set down a lapping disk 12 or remove it from one of the rails 322 or the support heads 142. The other and The lower end 370 of the pivot shaft 342 has a drive gear 372 which is attached thereto by means of a screw or the like. is attached. The drive gear 372 is suitable with a To be engaged to rack 374 carried on one end of the piston rod 376 of the pneumatic cylinder 378 will. The cylinder 378 is through a suitable operating arm attached to the horizontal frame member 316. In order to have greater softness and movement of the rack 374 and one To be able to achieve correspondingly smooth rotation of the pivot shaft 342, the pneumatic cylinder 378 is additionally still provided with a hydraulic cylinder, not shown. It will be seen that a hydraulic cylinder includes a practically incompressible liquid compared to air and therefore any tendency for one uneven movement of the rack reduces and even switches it off completely.

Behind the gear 372, a first ring 380 is firmly connected to the pivot shaft 342, which is on a lubricating bronze bush 383 rests, which is carried by a tubular support sleeve 382.

can accommodate a support station 400. The ends of the support pin 400 are secured in sockets 396 and 397 carried by supports 398 and 399. A spacer sleeve 401 is on attached to the upper surface of the pivot arm 390 and serves to support part of the load generated by the weight of the Device 394 to be transferred to the swivel arm 390 through the supports 399.

As can be seen from Figures 16 and 17, the support strips are 398 and 399 welded to the rear of the support plate 402. A pair of spring loaded pins 430 are attached to the free end of arm 380 on opposite sides of borehole 395. The pin assembly 403 allows pivoting of the device 394 when this is moved, as well as a slight alignment of the shafts 13 of the disk assemblies 12 when the latter is picked up will. A fixed clamping arm 404 with a clamping chuck 405 and a pivotable movable clamping arm 406 including the chuck 407 are attached to the front of the plate 402. A recess 408 is in the Chuck 407 provided to a smaller diameter !: of the shank 13 of each lapping disc with a loose fit and small Record game. This is desirable in order to avoid any excess bending stress in the shank of the lapping disks 12 to avoid, since the latter are moved fairly quickly from the circulating conveyor 300 to the turntable 50 and vice versa. It will be noted that most of the weight of the lapping disks 12 resides in the disk element 16 itself and not in the Shank 13 is located. It is therefore necessary that a slight play or a pivoting movement of the disk unit 12 is provided is who this is detected between the chucks 405 and 407. The movable gripping arm 406 includes a swivel! arm 410 pivotally mounted on plate 402 at 412. | A connecting part 414 is with the free end of the swing arm 410 and in turn firmly connected to the free end of the piston rod j 416. The latter is controlled by the pneumatic cylinder J.

According to FIG. 16, an adjustable stop 422 is provided for the inevitable limitation of the extent of the working movement of the pivoting array 410 in the clockwise direction. It has been found that, in some examples, the movable gripping arm 406 swings outward, that is, from of the turntable 50, while in other examples this oscillation also takes place in the direction of the turntable can. This fact emerges from FIG. 11 if one keeps in mind that the one provided with a recess Chuck 407 is on the movable gripper arm 406 and swings away from the other gripper chuck 405. The movable gripping arm 406 is beveled at 424 / around the Contact with actuator 425. in connection with the microswitch 426. The microswitch 426 must be actuated in order to be able to give a signal in the control circuit according to FIG. 1, whereby a switching movement of the turntable 50 can be done.

as soon as the lapping disks 12 have been brought to the circulating conveyor 300 on the lapping machine 10 and vice versa, according to FIG Figure 3 will address to operate the main drive motor 78. which causes the switching movement of the turntable 50. These Switching movement only takes place when certain microswitches are closed. These microswitches are e.g. with a touch display of the complete retraction of the Grooved element connected, the magnetic clamping means on or off, whereupon a return movement of the pivot arms 390 with the gripping device 394 in the usual rest position and the return movement of each gripping device 394 in the usual open position, scanned by microswitch 426 according to; figure he follows.

It should be added that the electric drive motor Ml in Figure 3 is the main drive motor jsb, which the Switching movement of the turntable 50 causes, and which is shown at 78 in FIG. The motors M2 and M3 in figure 3 are shown at 92 and 96, respectively.

With reference to Figures 3 and 4, it should be noted that the timer Tl is adjustable and can regulate the time between switching movements. The timepiece T2 comprises a series of rotatably driven cam wheels, which the time contacts T2C1 to T2C6 in a predetermined Close sequence. This will be apparent from the description that follows. With reference to the figure j 3, the mode of operation of the lapping machine 10, controlled by the circuit according to FIG. 3, will now be described.

For the time being, it should be assumed that any previous operation of the lapping machine 10 has been completed and that the part of the polar circle that includes the photocell PC, in series with the limit switches LS14 through LS19 is completed by the relay R3. The relay R3 is therefore energized and consequently the normally open Relay contact R3C1 closed. Pressing the start button will energize the relay R1 and the circuit remains open due to the closure of the normally open relay contact RlCl. At this point there are different electrical processes take place. There are the following: an excitation of the timer Tl by the normally closed contacts LS13 (which are in the actuated position) causes the normally open timer contact TlCl is closed. This in turn sets the excitation of the motor relay MIR by the normally

closed start magnet contact SMCl and the normally closed limit switches LS9 and LS12. The running of the motor Ml causes the turntable 50 to switch, while the excitation of the relay MIR connects the running of the motors M2 and M3 by opening the relay contact MlRC2 (nc). After completion of the switching movement, the motor relay M2R is excited by the terminal point 10 (adjacent to the limit switch LS12 according to Figure 3) and the normally closed motor relay contact M1RC2. An excitation of the motor relay M2R then allows the normally open motor relay contact M2RC1 to be closed and the motor relay M3R to be excited. Since the motor relay MIR has been energized, it ^{can be seen from Figure 3 u} that closing the normally open motor relay contact M1RC3 will allow the relay R4 to be energized and the normally open relay contact R4C2 to be closed and held in this position. An excitation of the relay R4 pulls in and closes the relay contact R4C1, whereby the starting magnet SM is excited through the normally closed motor relay contact M3RC1, through the return line terminal point 9. An excitation of the timer Tl has pulled out and closed the normally open timer contact TlCl . Control lamp PLl indicates when one of the limit switches LS9 or 1LS12 is open before switching. The motor relay contact MlRCl (nc) is opened by the excitation of the motor relay MIR. If either LS9 or LS12 is open, the relay contact MlRCl is closed and the control lamp PLl lights up. The energization of the starting magnet SM thus allows the normally open starting magnet contact SMC2 to be closed and the timer T2, which is a cam timer, to be energized.

All of the foregoing happen more or less together, although it will of course be seen that individual relays and contacts must be closed before another part of the circuit can be completed.

These various functions will occur practically immediately after you press the start button. The left vertical Line in Figure 4 represents the starting point at the point in time when the start button has been pressed. It becomes something Time will pass before timer T2 is energized, as shown by the next vertical line in Figure 4. It will also envisions that an energization of the motor relays MIR, M2R, and M3R in turn causes the normally closed cause open motor contacts MlCl, M2C1 and M3C1.

After pressing the start button, if the photocell PC and the limit switches LS14 are closed by LS19, the relay R3 can be energized (and this relay is consequently j kept excited by pulling in the relay contact R2C1, caused by the closing of the timer contact T2C2), is the first movement that takes place that that which the main turntable 50 by means of the motor Ml, shown at 78 in Figure 10, executes a switching movement. These Switching movement of the main turntable 50 actuates the limit switch 290 according to FIG. 6. Since the motor relays M2R and M3R at the same time Time have been energized like the cam timer T2, v / ground through the motor relays the drive motors M2 and M3 (92 and 196 in FIG. 10) and through these the drive shafts 95, 100 and 102 (Figure 10) are set in motion. When this happens, the jigs 150 that are inside of the lapping zones 1 and 3 according to Figure 1 are to begin to rotate, as well as the clamping devices 150, which are in the vicinity of the loading station 2 and the unloading station 4 in the switch position. A start of the Uocken timer T2 will cause the timer contact T2C1 to close after a predetermined time interval. To this Way, the solenoid Sl is actuated, which in turn actuates the pneumatic cylinder 266 according to Figure 6, whereby the polygon 236 is brought into contact with the nylon tape 226 on the retaining ring 201 of each jig 150, J thus the switch position at the loading and unloading station

2 and 4 are occupied. These two clamping devices 3SO turn until the recess 234 in the insert 230 comes in the direction with the polygon 236.

When this happens, the preload pressure causes the membrane edge are indented into the recesses 234 until they are fully inserted. The full use of this polygon is indicated by the contact of the support arm 244 with the measuring sensors 281 on the limit switches LS10 and LSII with 280 in Figure 6. A rotation of the cams in the cam timer j T2 has the consequence that the timer contact T2C2 is closed I

ι is, whereby the solenoid S3 is energized, which in turn j Rotary cylinder 242 actuated, which sets the polygon 236 in motion. Such movement of the polygon 236 causes the magnetic clamping means 172 at the loading station 2 and the unloading station 4 to be "switched off" will. The control lamp PL2 also lights up to indicate that a rotation of the polyedge 236 has taken place, and that the clamping means 172 are in the non-magnetized state. Both clamping means 172 are therefore in front of a Withdrawal of the grooves 236 "switched on". As can be seen from the control circuit in FIG Relay R2 energized when the timer contact T2C2 is at the connection point 13 is closed. When this happens, the normally open relay contact R2C1 is closed and the relay R3 can remain energized regardless, e.g. if the photocell beam is interrupted as well as the circuit by the presence of an operator near the machine when a workpiece is removed from the fixture 150 at the unloading station 4 is taken. On the other hand, the relay R3 is only controlled by the photocell PC when the Timer confection T2C2 is switched back to terminal point 14, furthermore the relay R3 through the limit switch LS14 through LS19 controlled.

In the chronological sequence, the timer contact T2C3 is closed, whereby the magnet S5 is excited ^ and this in turn actuates the pneumatic cylinder 418, one end of which is connected to the disk gripping device, generally designated at 394 in Figure 14, is connected.

of the lapping disks 12 from the lower switching position of the rotary disk 50, so that this is then in the disk support fork 322 carried by conveyor chain 320 are located. It should be noted again that since the switching movement the turntable 50 and the drive movement of the conveyor chains 320 of the conveyor device 300 originate from a drive shaft, the output shaft 74 of the main gear reduction unit 76, whose movements are synchronous. This is necessary to secure the disk support fork 322 that was previously was empty, is moved to such a position that a disk 12 is returned from the lapping machine to the conveyor 300 can be brought.
