Field of application of the invention

The invention is applicable to compensate for the forehead deviation of a sprocket 6 spanned on a gear cutting machine. "With a vertical gear axis.

Characteristic of the known technical solutions

The alignment of the front wheel of gears is usually done by inserting inserts or adjusting by means of pressure screws.

A disadvantage is to be considered here that zi: r carrying out several work sequences is a high amount of time for aligning orforderlicn.

Another disadvantage is that when using inserts or pressure screws point-shaped force transmission on the gear and en the clamping surface occur, causing Stiff losses and deformation of the components, eg. B. the carrying guides of r> ehnschon arise arise.

With DE-OS 2808608 a device for facilitating the alignment of heavy workpieces aif a machine table has been proposed in which raised by hydraulic means and pendulum supports the workpiece and can be aligned by mechanical tinnchlungen regard round and Stirr.lauf. In this device, the disadvantage remains that the> .g. point-like power transmission on the machine table with its unwanted side effects ointritt.

In addition, there is the disadvantage that the workpieces are distorted during clamping by an alternating arrangement of support and Spsnnstellen, especially in sprockets low stiffness.

Another disadvantage is that when clamping a workpiece, in particular when using more than three support points, the alignment accuracy achieved during alignment is impaired again.

Object of the invention

It is the object of the invention to increase the productivity of the gear cutting machines by reducing the time required for aligning the gears.

Explanation of the essence of the invention The invention has for its object to make a device of the type mentioned so that the automatic Error compensation of the forelimbs Elements for measuring word detection and the alignment of the gear on the Vverkstückaufnahme are arranged. According to the invention the object is achieved in that, based on the axis of the rotary table, adjusting elements and

associated inclination axes of a clamping plate in an angular arrangement on the rotary table are arranged and that for this purpose, fixed to winkelobhängiyen rotation of the rotary table and fixed to each other, an electronic measuring device for the

Spurlaufabweichung the gear and an electronic measuring device for the rotational position dss rotary table to ° assigns The connecting ring is through you tilting lugs with the lower plate of the rotary table and with the clamping plate of the Clamping attachment connected. To Spinlauslage in the tilting axles tension springs are attached to the lower plate and the clamping plate, the pairs and

are arranged next to the pitch axes. For inclination of the clamping plate relative to the lower plate, at least one adjusting element is arranged for each axle.

Eino another embodiment provides that arranged for each tilt axis two Vorstellelemente offset by 180 ° and

are adjustable in opposite directions.

The adjusting elements are formed by electric motor-driven mechanical elements, such as wedges or eccentrics. The invention will be explained in more detail below using an exemplary embodiment. In the accompanying drawings show: Fig. 1: the view of the device 2: the device in a sectional view (section B-D) 3 shows the device in section (section A-A) On the bed 1 of a gear cutting machine a rotatable rotary table 2 is mounted. On the clamping surface of the rotary table 2 is

a clamping device .tentrisch clamped.

It consists of the clamped with the rotary table 2 lower plate 3, the clamping plate 4, on which a gear 11 directly or

indirectly spanned by a clamping attachment 10, and a connecting ring 5. on the one hand by means of bolts 6 to the

Inclination axis 16 with the lower plate 3 and on the other hand by means of bolts 6 about the inclination axis 15, by 90 ° relative to the Inclined axis 16 is arranged, is connected to the clamping plate 4. It is possible that lower plate 3 and rotary table 2 alo a part are executed. For game display between circuit board 3 and clamping plate 4 are on both sides of the bolt 6 of the tilt axes 15; 16 Extension springs 7 arranged on the lower plate 3 to the clamping plate 4. For the inclination of the clamping plate 4 relative to the Lower plate 3 are at least one adjusting element 8 for inclination about the inclination axis 16 and at least one Adjustment 9 for inclination u.n the inclination axis 15 is provided. It is also possible to provide two mutually acting adjustment elements 8 and 9, respectively. As adjusting elements 8 and 9 sin-J ζ B. Getriobemotore in conjunction with eccentrics, wedges or spindles more common Design conceivable. To provide the energy required for the displacement between the rotary table 2 and the bed 1 is a Energy transmission system 18, e.g. in the form of known slip rings, provided. On the bed 1 are a burned on electronic measuring device for the Stirnlaufbweichung 13 and one also on

known electronic measuring device for the rotational position 14 of the rotary table 2, z. B. an incremental rotational

Encoder, in their angular position, relative to the axis of the rotary table 2, fixed to each other. On the location of the electronic Measuring device 13; 14 are in a certain angular position to these the inclination axes 15, 16 and the adjusting elements 8; 9

arranged.

The electronic measuring devices 13 and 14 are with a control and processing unit 17 and this wiodeium on the Energieübertrapungssystem 18 connected to the adjusting elements 8 and 9. The operation of the device is wio follows: When rotating rotary table 2 is measured by the measuring device 13, the Stirnlaufabweichung on Prüfbund 12 and through

the measuring device 14 orgestaßt to each associated rotational position of the rotary table 2. From the measured values of the

Measuring devices 13 and 14 have been in the control and Rochonoinh'jit 17, the adjustment amounts for the adjusting elements 8 and 9 respectively

calculated and their adjustment initiated.

After this first compensation of the forehead deviation, the measuring and adjusting process can be initiated again and as often

be repeated until the head deviation is within predetermined limits.

The advantage of the solution according to the invention is that the alignment of the gear in terms of his frontal running

automated and targeted executable. As a result, a previously time-consuming operation of the auxiliary time category is substantially shortened and independent of the manual skill of the operating personnel.
