Description

This invention relates to a machine tool industry and can be used in the manufacture of gear shaping machines.

The purpose of the invention is the expansion of technological capabilities by creating the possibility of chiseling various types of wheels (including block ones) with various types of chisels (including those with modified profile teeth) and improving the processing accuracy by eliminating the accumulated error of the dolby step. ka

The drawing shows a general kinematic diagram of a gear shaping machine.

The motor M, through the setting body i, for example, the speed box of the drive shaft 1, K1) of the hub disk 2, informs the ram 3 of the cylinder 4 to reciprocate (E,).

Consistent rotation of the workpiece 5 and the chuck A () - the rolling movement is communicated from the drive shaft 1 through a kinematic pair 6 through a circular feed chain, including reverse P, tuning organ ij, for example, a guitar

interchangeable wheels, and then through link / chain connections along the rolling chain, including adjusting organ i, for example, interchangeable wheels, kinematic pair 8, and worm pair 9 and 10. Adjustment body ig serves to change

rolling speed (), i.e. for setting the circular feed amount. Adjusting device i is used to adjust the run-in chain and match the movements of B and Bj, i.e. to adjust to the specified number of wheel teeth.

The ram control circuit during the idling period includes a discrete-action mechanism connected in series, for example, a cam clutch I1, a summing mechanism 12 and a setting element iy. The chain is connected to the drive shaft 1 by a kinematic pair 13 and provides for a hollow 4 discrete turn. In the upper position of the cam, the cam 14 includes a cam clutch 11 (B) by a multiple of its teeth at the beginning of each working stroke. Adjustment i is used to adjust the amount of additional rotation of the slot at the beginning of the working

where N is an odd integer; Z is the number of teeth of the blade.

The kinematic insertion chain includes a kinematic pair 15, the igp adjustment body for the insertion feed amount, the insertion cam Kgp and informs the spindle head the insertion motion P by an amount equal to the height of the tooth of the wheel being cut.

The movement of the tap P of the table (not yet

The shaft 1 and the crank disk 2 of the stolisel from the hammer end 4 are connected with the cutting movement P.

From the drive shaft 1, through the kinematic pair 6, the feed guitar i, the workpiece is reported to rotate B, which is matched with the rotation B of the chisel along the rolling chain, including rolling i, kinematic pair 8, and the worm pair 9 and 10.

In the upper position of the cam, the cam 14 activates the discrete action mechanism 11, for example a cam clutch, which receives rotation from the drive shaft 1 through the kinematic pair 13 and turns off after its complete rotation. This movement is transmitted to the case of the summing mechanism 12 (input 17) and then through the guitar of the interchangeable wheels of the chain i communicates the additional discrete turn of B. at an angle

The summing mechanism 12 adds two movements: run-in | unbroken, arriving at input 18, and an additional discrete, arriving at input 17. The cumulative movement from the output from the kneading mechanism is communicated by a bevel 4.

at the beginning of the working stroke, it becomes possible to gear the wheels with a chisel with modified teeth and a calculated profile alternating through one along a pitch circle.
