SU604638A1 - Machine for chamfering the ends of gear teeth - Google Patents

Description

one

The invention relates to the field of metalworking.

Known machines for chamfering the ends of the teeth of a gear mounted on a spindle, having a rotational drive, are a fasco-detachable cutter housed in a tool holder mounted on an axis and provided with a control element 1.

The disadvantage of these machines lies in their low productivity due to the periodic dividing process and the need (to avoid breakage of the dividing mechanism) to strictly synchronize the process of dividing the wheel and moving the tool.

The purpose of the invention is to simplify the design by eliminating the division mechanism.

For this, the control element is elastically connected to the tool holder, which is fixed on the axis with the possibility of swinging relative to the end of the gear, the spindle of which is connected with the drive with the possibility of continuous rotation. The controllable element is designed as a hydraulic cylinder.

FIG. 1 shows a machine, a general view; in fig. 2 is a chamfering pattern at the ends of the teeth.

On the base 1 mounted stand 2 and spindle 3 products. The rack 2 has the ability to reciprocate the movement on the frame using the flywheel 4. On the rack 2 mounted swivel plate 5, rotates

using the flywheel 6. On the plate 5 is mounted with the possibility of vertical movement by means of the flywheel 7 instrumental support 8. In the support 8, the axis 9 is rigidly fixed, on which the tool holder 10 with the cutter I is rockingly attached. The hydraulic cylinder 12 is located on the support 8, the hydraulic rod 13 of the hydraulic cylinder presses toolholder 10.

The gear wheel 14 is fixed on the shnindle 3, connected to the engine 15 through the gearbox 16.

The gear wheel interacts with the sensor 17, giving the command to change the force to press the tool holder 10.

The machine works as follows. Depending on the size of the gears to be machined, using the flywheels 4, 6 and 7, the caliper 8 is mounted into the working

position The engine 15 rotates the spindle 3 through the gearbox 16 with the gear wheel 14 at low speed. When the spindle 3 begins to rotate in the direction of the arrow B (Fig. 2), the cutter 11 removes the chamfer from the tooth 18, and

the tool holder 10 under the action of the pressure transmitted by the tooth 18 to the cutter 11, overcoming the pressure of the rod 13 of the hydraulic cylinder 12, begins to rotate around the axis 9 in the direction indicated by arrow B. When the tool 11 removes the chamfer from the tooth 18, and the tooth 18 pulses the tool, the tool holder 10 under the action of the rod 13 will turn in the direction of arrow G to the initial position, which will be the beginning of the treatment of the next tooth 19.
