Abstract

The invention relates to the automation of technological processes in mechanical engineering and is intended for the orientation and fixation of parts such as gears. The invention allows to expand the technological capabilities of the device by increasing the range of sizes of orientable gears. The orientation of the part 9 is dried, when the tip of the retainer 2 hits the cavity between the teeth of the part 9. If the tip of the retainer 2 hits the top of the tooth, as the device moves further, the retainer 2 stops and the body 1 with the pusher 3 continues to move, compressing the spring 5. At the same time, the pusher 3 acts on the side surface of one of the teeth of the part 9 and rotates it until the latch tip 2 slides off the top of the tooth and under the action of the spring 5 falls into the cavity between the teeth, finally turning and fixing (guide) part 9 in the required position. Installing the pusher 3 in the housing 1 with the ability to adjust its position in the direction of movement of the latch 2 and perpendicular to it ensures the impact of the pusher on the lateral surface of one of the teeth of the oriented part 9 regardless of its module (schag) and the number of teeth. 4 il.

Description

The invention relates to the automation of technological processes in mechanical engineering and can be used to orient and fix parts, in particular gear wheels, splined shafts, sprockets.

The purpose of the invention is the expansion of technological capabilities through its re-adjustment.

FIG. 1 shows the device at the moment of contact of the fixer with the apex of the tooth of the oriented part, section; in fig. 2 - the same, at the time of the start of the work of the pusher; in fig. 3 - the same, at the moment of fixing (orientation) of the part; in fig. 4 shows section A-A in FIG. one.

The device includes a housing 1, a retainer 2, a pusher 3 and a slider 4. The latch 2 is mounted in the housing 1 movable relative to the latter and spring-loaded 5. The pusher 3 is mounted in the housing 1 on the slider 4 movable relative to the latter. The slider 4 can move along the guide 6 of the housing 1. Fixing the pusher 3 in the slider 4 and the last on the guide b of the housing 1 is carried out respectively with screws 7 and 8. The latch tip 2 is made in the form of a cone, and the angle of the cone is selected so that the point of the retainer 2 is not in contact with the bottom of the cavity of the orientable gear 9. The nuts 10 are intended to regulate the travel of the retainer 2.

The device works as follows.

If, when the device (drive is not shown) is moved to the oriented part 9 (for example, a gear), the latch tip 2 falls into the cavity between the teeth, then the final door is closed and the gear 9 is fixed in the required position.

If the tip of the retainer 2 falls on the top of the tooth (Fig. 2), then

When the device is close to the part 9, the latch 2 stops, and the body 1 with the pusher 3 continues to move, compressing the spring 5, while the pusher 3 acts on the side surface of one of the teeth and rotates the part 9 until the latch tip 2 slides off the top tooth and under the action of the spring 5 does not fall into the cavity between the teeth, finally turning and fixing (orienting) the part 9 in the required position (Fig. 3). After that, the movement of the device is stopped.

The reliability of fixing the part 9 is ensured by the elasticity of the spring 5.

When the device leads away from the orientable part 9, the body 1 with the pusher 3 moves initially, and the latch 2 under the action of the spring 5 remains in the cavity between the teeth until the nuts 10 are pressed into the body 1, then the latch 2 leaves the cavity between the tooth Moving along with the housing 1 and the pusher 3, it returns to its original position.

When adjusting the device to a specific size-oriented parts, the pusher 3 must be installed so that it does not prevent the part from turning and fixing the part 9.
