Description

DETAILED DESCRIPTION OF THE INVENTION The present invention is a machine for finishing the tooth profile of a toothed workpiece rotatably supported on a machine frame by aligning a gear-like tool with the workpiece. The tool head is rotatably supported above the tool head, and due to changes in the intersecting angle between the axes of the workpiece and the gear-shaped tool,
It is supported by a feed slide so as to be rotatably adjustable about a common perpendicular line between the workpiece and the tool, and (a) this feed slide is guided in a guide support so as to be able to move vertically, and this guide support is For machining a crowning tooth profile and/or a conical tooth profile on a workpiece, the feed direction of the tool relative to the workpiece is adjusted by a tilting pin so that the workpiece and the tool are tilted to both sides from a neutral position having a common perpendicular line. for adjustment, it is supported on a pivot plate which is pivotably and fixably arranged on a vertical slide, and the axis of the tilting pin is perpendicular to the vertical axis of rotation of the tool head in the neutral position, and (b) The present invention relates to a type in which the feed slide is guided to the swivel plate via linear guides and slides or the like which can be tilted variable and fixed.

This type of machine is covered by patent application no.
It is proposed by No. 29279763. This machine is suitable for producing crowning or conical tooth profiles. A tool carrier carrying out a feed movement is suspended so as to be tiltable about a horizontal axis, which tool carrier is guided to the stationary part via an adjustable, inclined linear guide. Here, the feed motion is performed in a plane approximately parallel to the tool axis.
Refers to the movement of the tool relative to the workpiece. In connection with the inclination of the linear guide, the tool support and thus the tool are inclined during the feed movement and at the same time plunge feed relative to the workpiece (approximately radial movement in the direction of decreasing the distance between the workpiece axis and the tool axis). exercise).

Generally, the plane of rotation of the tool is directed toward the axial center of the workpiece. For wide workpieces, the inclination of the tool (referred to as camber angle in this application) towards the end of the feed movement
It is preferable to increase or otherwise reduce the plunge feed rate to obtain a relatively wide pressure surface on the tooth flank, for example. This can easily be achieved with curved guides, but such guides are expensive to manufacture and the guide slides must be specially designed.

SUMMARY OF THE INVENTION The object of the invention is to provide a simple correction device for shaving crowning tooth profiles and similar finishing operations, which can also be used in known machines.

The gist of the present invention that solves this problem is as described in claim 1.

According to the present invention, by arranging the eccentric tilting pin and the eccentric lever, it is possible to reduce the plunge feed amount of the tool. This is because the eccentric lever always raises the guide support and thus the tool slightly, regardless of the direction of the feed movement. This causes the tool to be positioned perpendicular to the workpiece teeth at each point of its curved trajectory or at another desired angle. The degree of decrease in the plunge feed amount can be changed depending on the position of the protrusion. Instead of projections, templates formed in connection with the workpiece can be used. This template is in any case easier to manufacture than a guide curved in two directions. An advantageous embodiment is defined in claim 3. The template allows the crowning to be changed to the desired shape. However, with this machine using a linear guide, it is not possible to machine conical tooth profiles or conical tooth profiles with crowning. An embodiment in which a conical tooth profile can also be machined is shown in claim 4. By varying the length of the arm connecting the feed slide and the linear guide or slide, an inclined position of the feed slide and thus of the guide support can be obtained. Thereby, the longitudinal movement of the feed slide or the tool is
It is possible to obtain a direction inclined relative to the workpiece axis by an amount corresponding to the desired degree of conicity.

In order to be able to process a conical tooth profile with crowning, the embodiment described in claim 5 is necessary, and furthermore, the embodiment described in claim 6 is required.
The embodiments described in Sections 7 and 8 are possible. To obtain a conical tooth profile with crowning,
The starting position of the guide support or feed slide (the position where the axis of rotation of the tool head 13 and the axis of the tilting pin 100 are perpendicular to each other) must be inclined;
At the same time, the eccentric lever and the control lever supporting the protrusion or template are positioned parallel to each other,
The conical tooth profile produced by the inclined position must be provided with a crowning that corresponds to the position of the projection or the shape of the template.

Next, the present invention will be specifically explained with reference to the illustrated embodiments.

As shown in FIG. 1, a vertical column 2 is fixed to one end of a machine bed 1. This column 2 is provided with a vertical linear guide 3 facing the free end of the machine bed 1, inside this linear guide 3:
A vertical slide 4, which at least partially overlies the same free end of the machine bed, is arranged in a height-adjustable and drivable manner. For the drive, a step-by-step motor 5 is provided on the column 2, which drives a screw spindle 8 via a spur gear transmission 6,7. This screw spindle 8 is connected to the vertical slide 4
It is screwed into a spindle nut 9 fixed to the.
The vertical slide 4 has an adjustment slide (see Fig. 4) on the lower side, and a rotation guide 11 is provided on the lower side of the adjustment slide.
A tool head 13 is mounted therein and is rotatable about a vertical axis 12 (this vertical axis 12 is the same as the common perpendicular between the tool 14 and the workpiece 20). A tool 14 is rotatably supported within the tool head 13. Tool 14 is a known gear-shaped shaving cutter or other tool suitable for finishing operations. The tool 14 projects downward from the tool head 13.

A vertical guide 15 (see also FIG. 2) is provided on the machine bed 1, and two tailstocks 16 and 17 are arranged within the vertical guide 15 so as to be vertically movable and positionally fixed. . The equipment necessary for this is known and is therefore not shown. The two tailstocks are, for example, equipped with centers 18, 19 (these centers are also known), by means of which the workpiece 20 can be gripped. The center 16 located near the column 2 is movably arranged within the recessed portion 21 of the column 2 so that even a long shaft-shaped object can be gripped.

In order to machine the workpiece 20, the tool 14 can be brought close to the workpiece 20 in the direction indicated by the arrow 22 and can engage the workpiece. The device for this approach is designed as the already mentioned step-by-step motor 5 and vertical slide 4. For the rotational drive of the tool 14, a drive motor 25 is provided in the column 2, which drives a belt transmission 26 and a flexible shaft coupling 2.
7 and a spur gear transmission 28, 29 mounted in the tool head 13 to drive the tool in rotation. This drive motor 25 may be an electric motor or a variable hydraulic motor. In the case of a hydraulic motor, the belt transmission 26 may optionally be omitted. A hole 30 is provided in the column 2 for passing the flexible shaft coupling therein.

The adjusting slide shown in FIG. 4 consists of three main parts, namely a pivot plate 71, a guide support 72 and a feed slide 73, which are arranged movably relative to each other. The rotating plate 71 is the rotation guide 7 of the vertical slide 4 already mentioned.
4 so as to be rotatable about a vertical axis 12 and fixed in position. As a result, as shown in FIG.
5, 75', 75'' can be set arbitrarily.Swivel plate 7
1, a guide support 72 is eccentrically supported via a tilting pin 100 so as to be tiltable about a horizontal tilting axis 77. This point will be explained in more detail. The guide support 72 has a vertical groove on its lower surface, into which a vertical guide 78 of the feed slide 73 is guided. The vertical guide 78, like the rotary guide, is well known and will not be described in detail. Vertical guide 7
8 is oriented at right angles to the tilting axis 77. Similar to the linear guide 3 described above, this vertical guide 78 allows the tool 14 to be placed above the workpiece 20 held in place.
It is located in a high place so that it is out of the range where chips are scattered. This ensures that no chips accumulate, at least in the parts used during the working cycle, and therefore no wear of the guideway occurs. The rotary guide 11 of the tool head 13 as well as the rotary guide 74 (FIG. 1) of the pivot plate 71 are also located outside the range of flying chips and are therefore not contaminated by chips.

As already mentioned, the tool head 13 is pivotable about a vertical axis in the rotary guide 11 of the adjusting or feed slide 73. By this,
Axis intersection angle γ between tool axis 41 and workpiece axis 42
(see Figure 3) is adjusted. In this case, the tool axis 41 and the motor axis 24 intersect in the horizontal plane at an angle equal to the axis intersection angle γ, which angle is compensated by the flexible shaft coupling 27. At the same time, the tool axis 41 and the motor axis 24 are displaced in the height and horizontal directions due to the dimensions of the workpiece and the vertical and horizontal movements of the tool during each operation. Variations and changes in spacing are also compensated by the flexible joint 27.

The step-by-step motor 5 brings the tool closer to or away from the workpiece in the direction of decreasing center distance. The change in speed of the step-by-step motor is transmitted via spur gear transmissions 6, 7 and an almost friction-free linear guide 3 to the vertical slide 4, thereby allowing finely adjustable approach and quick return of the tool. becomes possible. The holding of the vertical slide 4 in a predetermined position is carried out, for example, by means of a hydraulic tightening device or the like, but these devices are likewise known and will not be described in detail. In order to obtain a feed movement in the guide support 72 (see feed directions 75, 75', 75'' in FIG. The feed slide is reciprocated by means of this double-acting hydraulic cylinder. In this manner, a tool 14, for example a gear-shaped shaving cutter, is reciprocated over the entire width of the workpiece. The control means for reciprocating movements and for plunging the workpiece or for automatic working processes are known and need not be explained here nor are they shown.

In order to crown the workpiece 20 in relation to the feed direction 75, 75', 75'' of the tool 14, a simple device is mounted on the adjusting slide (see FIG. 5). arm 8
6, and a linear guide 8 is provided at the free end of the same arm 86.
7 is installed. This linear guide 87 is fixed to the arm 86 so as to be tiltable about a horizontal axis 88 (see FIG. 4) oriented parallel to the tilting axis 77. The rotating plate 71 includes a cantilever beam 89, and a slider 90 is rotatably supported on the free end of the cantilever beam 89. A linear guide 87 is guided within the slit of this slider 90. When the colinear guide 87 is adjusted horizontally and tightened and fixed,
The feed slide 73 performs normal linear reciprocating motion. When the linear guide is rotated clockwise by an arbitrary angle β and tightened and fixed as shown in FIG. is lifted up by the sliding guide of and simultaneously moves to the left. Since the feed slide 73 is tiltably suspended on the rotating plate 71 by the guide support 72, the feed slide 73 and, by extension, the guide support 72 can be tilted counterclockwise as shown by the arrow 94 in FIG. . Conversely, when the feed slide 73 is moved to the right, the arm 86 is lowered and
The feed slide 73 and the guide support 72 are tilted clockwise as indicated by arrow 95. This tilting movement of the feed slide 73 causes the tool 14 to tilt relative to the workpiece. This slope is called camber.
The angle α of this camber (see Figure 6) is the linear guide 8
It changes depending on the change in the inclination angle β of 7. Tool 14
The rotation plane 91 of is generally directed to the center point of the face width projected onto the workpiece axis. This also applies to normal tooth profiles, conical tooth profiles, crowned tooth profiles, and crowned conical tooth profiles. For wide workpieces with high feed rates, it is often necessary to reduce the plunging feed rate of the tool 14 caused by the tilting movement of the tool head 13, at least towards the end of each movement, for example in order to obtain a relatively wide contact surface. Must be. For this purpose, the device described below is useful.

A tilting pin 100 on the pivot plate 71 has a first diameter 10
Supported by 1. The tilting pin 100 is the first
is supported on the guide support 72 by a second diameter 102 offset with respect to the diameter 101 of the guide support 72 . The axis 103 of the second diameter 102 is offset by a distance 104 with respect to the tilting axis 77, which is also the axis of the first diameter 101, and is orthogonal to the already mentioned pivot axis 12. At this diameter 101, an eccentric lever 105 is fixed to the tilting pin 100 in a non-rotatable manner.

Furthermore, a control lever 106 is attached to the rotating plate 71 via a connecting piece 107 so as to be able to swing about an axis 108, and the control lever 106 is pivotally supported by the guide support 72 via a link lever 109. There is. On both sides of the connecting piece 107, one protrusion 110, 111 is provided on the control lever 106 with a distance Q between the protrusions 110, 11.
One free end 112 of the eccentric lever 105 is placed on 1. The other free end 113 is connected to the guide support 7
It is loaded by a compression spring 114 supported by 2. This compression spring 114 ensures that the eccentric lever 105 is brought into contact with the projections 110, 111. This device operates as follows. If the feed slide 73 moves, for example, to the left when the linear guide 87 is in the rightward downward position as shown in FIG. Tilt (solid line in Figure 6). This tilting movement is transmitted via link lever 109 to control lever 106, which likewise pivots counterclockwise about axis 108. In doing so, the free end 112 of the eccentric lever 105 is pushed up via the projection 111, whereby the guide support 72 is also lifted, since it is eccentrically suspended. This guide support 72
Due to the lifting of the tool, the tool also moves correspondingly upwards (see FIG. 6). When the feed slide 73 moves to the right, it, together with the guide support 72, tilts clockwise as already mentioned (double-dashed line in FIG. 6). This tilting movement is transmitted to the control lever 106 via the link lever 109,
The control lever 106 is similarly swung clockwise. At this time, the arm 112 of the eccentric lever 105 is pushed up via the protrusion 110, thereby causing the tool 1
4 still moves upward. In this way, the link lever 109, the control lever 106, the protrusion 11
0,111, the combination of the eccentric lever 105 and the eccentrically suspended guiding support causes the free end 112 of the eccentric lever to pivot upwards when the guiding support 73 is tilted, regardless of the direction of its tilting; This pivoting causes an upward movement of the guide support 72 and thus of the tool head 13 via the eccentric tilting pin 100, thus canceling out the plunging feed of the tool caused by the tilting of the feed slide 73. Protrusion 11
By adjusting the distances a and b between 0 and 111 and the axis 108, the amount of movement of the eccentric lever can be adjusted in advance. The movement of the eccentric lever 105 is
Instead of the protrusions 110, 111, a template 115 (see FIG. 7) fixed to the control lever 106 can also be used. In this case, the eccentric lever 105 rolls on this template 115 to some extent. The curved surface formed by template 115 is also formed by at least three adjustable cams. Fine adjustment of the camber angle or plunge feed is performed using the template 106.
The support point of the eccentric lever 105 on the top and the control bar 10
This is done by varying the horizontal distance c between the hinge point of the link lever 109 to 6.

In a further embodiment shown in FIG. 8, means are provided for adjusting the camber angle or adjusting the plunging feed. In this case, the control lever 106 is attached to the pivot plate 71 via a connecting piece 107 so as to be swingable about an axis 108 . Guide support 7
2, a connecting rod 116 is guided so as to be vertically movable. The lower end of this connecting rod 116 is supported on a template 117 attached to the feed slide, and the upper end of the connecting rod 116 is in contact with the control lever 106. During the movement of the feed slide 73, not only the tilting movement of the guide support 72 or the feed slide 73 is transmitted to the control lever 106, as already mentioned, but also an additional movement can be caused by the tilting movement, depending on the contour of the template. It is superimposed on the movement. Special shapes of crownings can also be produced by forming this template, for example as shown at 118a.

In a further embodiment shown in FIG. 9, the length of the arm 86 projecting upward from the feed slide 73 is adjustable so that conical tooth profiles can also be machined. In the illustrated embodiment, a threaded portion 86' is provided at the lower end of the arm 86, and the threaded portion 86' is connected to the feed slide 7.
3, and nuts 85 and 85' are screwed into threaded portions 86' on both sides of the hole, respectively. The length of the arm is adjusted by these nuts 85, 85'. Adjustment of arm length is also possible by other means. For example, as shown in FIG. 10, a threaded spindle 121 may be provided which threads into a threaded hole in the feed slide, or as shown in FIG. Both parts 122, 122' are provided with long holes, and screws 123, 123' passing through the long holes are used to connect both parts 122, 122'.
122' can also be adjustably coupled.

Generally, the length of the arm 86 is adjusted so that the feed slide 73 is horizontal. In this way, as already mentioned, normal tooth profiles or crowning tooth profiles can be machined. By making arm 86 shorter or longer than the length shown in FIG.
The feed slide 73 is inclined upwardly to the right or downwardly to the right as shown in FIG. In this way, the feed slide 73
When the tooth is tilted upward to the right or downward to the right, the feed slide moves in a plane that is inclined with respect to the workpiece axis depending on the inclination, and the tooth profile to be machined becomes a cone. As a prerequisite for this, the linear guide 87 must be adjusted horizontally and tightened (the linear guide 87 must be fixed horizontally,
If the length of the arm 86 is adjusted so that the feed slide 73 is parallel to the linear guide 87, the feed slide 73 performs a normal linear reciprocating motion).

On the other hand, if the linear guide 87 is tilted clockwise by an arbitrary angle β as shown by the two-dot chain line in FIG. 9, a crowned conical tooth profile is machined. The movement history of the feed slide 73 in this case is similar to the case of the crowning tooth profile explained in FIGS. 5 and 6. First, arm 86 is adjusted to the desired length. This causes the feed slide 73 to assume a correspondingly inclined position. The guide support 72 is similarly inclined. Link lever 109, control lever 10
6 and protrusions 11 arranged at intervals a and b.
Free end 1 of eccentric lever 105 via 0,111
12 is lifted. In order to obtain sufficient crowning, the eccentric lever 105 and the control lever 10
6 are preferably located parallel to each other in the starting position where the common perpendicular line between the center of the workpiece and the center of the tool is vertical. The link lever 109 is therefore formed in such a way that the distance between the point of contact between itself and the control lever 106 and the contact surface of the eccentric lever 105 on the projection can be varied. In the example shown in FIG. 9, the link lever 109 is for this purpose adjustable in length between the two pivot points, for example in two parts, as shown in the enlarged view in FIG.
4 and 124' have elongated holes, and both parts are connected to each other by screws 125 and 125' inserted into the elongated holes. By this means, the eccentric lever and the control lever can be adjusted to a normal position parallel to each other despite the tilting of the feed slide. The contact of the eccentric lever 105 with the projections 110, 111 is again ensured by a spring 114. The other functions of the device also correspond to the devices already described.

FIG. 11 shows another embodiment for adjusting the link lever 109. In this case, the link lever 10
9 is not directly pivoted to the guide support 72;
coupling piece 126 oriented substantially at right angles to itself;
This connecting piece 126 is pivotally connected to the shaft 127.
The guide support 72 is pivotably mounted on the guide support 72 and can be fixed to the guide support 72 by means of a screw 128 . By loosening the screw 128 and pivoting the coupling piece 126 upward to the right or downward to the right, the link lever 109 and thus the part of the control lever 106 with the projection 111 is moved upward or downward. After the control lever 106 reaches the desired position,
Screw 128 is tightened.

Instead of adjusting the link lever 109 for adjusting the control lever 106, both projections 110, 111
The height of the position of the contact surface of the eccentric lever 105 that comes into contact with may be adjusted. For this purpose, in the embodiment shown in FIG.
9 etc. is installed. This strip 129 is formed so that its vertical position and tilted position can be adjusted. For fixing the position of the strip 129, a screw 130 is provided which passes through the elongated hole in this case as well. The symbol c indicates the distance between the axis of rotation of the control lever 106 and the axis of rotation of the link lever 109.

The projections 110, 111 or the template 15 can be removed from the control lever 106 in order to prevent the correction devices described so far from acting. For that case, a screw 119 is provided at the free end 112 of the eccentric lever 105. When removing the protrusion or template, the tip of the screw 119 is aligned with the axis 108.
It is supported by a semicircular contour portion 118 provided on the connecting piece 107 or the template 115 so as to concentrically surround the connecting piece 107 or the template 115. In this way, the eccentric lever 105 is completely unaffected by the movement of the control lever 106.

The invention is not limited to the illustrated embodiment.

The tool is supported on a pivot plate rotatably and fixably disposed on a vertical slide for adjusting the feed direction of the tool with respect to the work so that the work and the tool can be tilted to both sides from a neutral position having a common perpendicular line; The axis of the tilting pin is perpendicular to the vertical axis of rotation of the tool head in the neutral position, and (b) the feed slide is connected to the swivel plate via a linear guide and slider or similar whose inclination can be varied and fixed. (c) The tilting pin 100 is provided with a first tilting pin portion 101 having an axis 77 located eccentrically with respect to the tilting pin axis 103 at both ends thereof. a second tilting pin of the tilting pin 100 which is rotatably supported on the pivot plate 71 by this first tilting pin portion and whose guiding support 72 is coaxial with the tilting pin axis 103; part 1
02 and the first tilting pin portion 1
01, an eccentric lever 105 is unrotatably arranged, and a free end 112 of this eccentric lever 105
The eccentric lever 105 is moved by the force of the spring 114.
(d) a semi-circular profile to which the control lever 106 is fixedly connected and directed towards the free end 112 of the eccentric lever; Connecting piece 1 with 118
07, the control lever 106 is suspended from the pivot plate 71 so as to be swingable about an axis 108 parallel to the axes of both tilting pin portions; , the free end 112 of the eccentric lever is supported on one or two projections depending on the position of the feed slide 73, and the tilting movement of the guide support 72 Connecting rod 11 movably guided in the body
control lever 106 supported by at least two projections 110, 111 on which the eccentric lever 1
05 is mounted, and the connecting rod 116
A tooth profile finishing machine characterized in that it is configured to trace a template 117 provided on a feed slide 73.
