Description

The invention relates to mechanical engineering, in particular to the treatment of the ends of the teeth of gear products.

The purpose of the invention is to simplify the design and increase the reliability of the device designed to debur the ends of the teeth of the cylindrical wheels mounted by the package.

FIG. 1 shows the proposed device, a general view; in fig. 2 - the same plan view; in fig. 3 is a section A-A in FIG. 2; in fig. 4 is a section BB in FIG. 2

The device consists of a transition strap 1, mounted on a fixed part - base 2 gear hobbing machine. The body 3 is placed on the bar 1 with the possibility of adjusting its position and fixing on the sleeves 4 and 5 relative to the bar by means of the latch 6 and the control handle 7. The body 3 has two rolling pins 8 on which the shank 9 of the bracket 10 is installed, made in the form of a comb, pinned by springs 11 to screw 12. In hole 13 of the bracket and in the quick-change sleeve 14 is placed a rolling pin 15, on which the tool holders 16 are mounted, pressed by the springs 17 supported on the rings 18. One end 19 of the tool holders 16 contacts the groove 20 of the comb 10 and the other gom end cutter 21 and has two rollers 22 which are arranged symmetrically with respect to the tool. The rollers are designed to prevent the cutter from getting into the grooves of the teeth of the machined wheel 23. At the end of the cutter 21, there is a threaded hole 24 into which an adjusting screw 25 is screwed, fixedly mounted on the tool holder 16 by means of a bar 26.

The device works as follows.

Before machining the parts, the device is in the initial position. In this case, the housing 3, together with the tool holders 16 relative to the strip 1, is moved with the aid of the handle 7 to the extreme position with subsequent fixation by its latch 6 entering the sleeve 4. Then install

the workpiece is attached to the mandrel and secured. After the parts are installed by pressing the handle 7 downward, the latch 6 locks 6 out of the sleeve 4, followed by a straight line movement by means of the handle 7, move the body 3 along the bar 1 until the latch axis 6 aligns with the axis of the sleeve 5, while the handle 7 is released and the latch 6 enters the bore of the sleeve 5. Next, turning the screw knob 12 through the tail 9 of the comb 10, together with the rolling pin 15 and the locking rings 18 arranged on it, move in a vertical position, while the springs 17 located on the rolling pin 15 compress, transferring the pressing force from the locking rings 18 of the cutter holders 16, and the limiting rollers 22 and the cutter 21 placed in the tool holders 16 come into contact with the machining surfaces.

During the cutting of the teeth by the cutter 27, the limiting rollers 22 will run around the end surface of the gear wheels 23, excluding the cutting of the incisors into the cut tooth cavities, and the cutters 21 adjusted to a certain depth of cut relative to the rollers 22 will reduce the burrs on the end surfaces at the same time groups of gears placed by the package. At the end of the technological operation, the worker by turning the handle of the screw 12 lowers the comb 10 together with the rolling pin 15 into the lower vertical position, while the springs 17 simultaneously open and the stop rings 18 come into contact with the upper plane of the tool holders 16, dragging them along with the rollers 22 and cutters 21 in the lower position, freeing the end surface

wheels from the last. Then, the worker by pressing the handle 7 removes the exhaust lock 6 from the centering sleeve 5, with the same handle 7, the worker bends the body 3 relative to the strip 1 in

0, an extreme position with fixation of the housing 3 along the sleeve 4, thereby ensuring free removal and installation of the next group of parts.
