Description

(54) LOADING DEVICE FOR SUBMITTING DETAILS OF TYPE OF GEAR WHEELS

one

The invention relates to a machine tool industry and can be used in automatic loading devices of assembly machines.

A loading device for feeding gear-type parts is known, which contains a spring-loaded slider with a gate mounted for reciprocating movement from a drive and a magazine 1.

A disadvantage of the known loading device is the impossibility of carrying out guaranteed insertion of the feed wheel with the gear wheel adjacent to the assembled product, previously installed at this working position, if the last teeth are randomly located relative to the slats.

The purpose of the invention is to increase the reliability of the device when applying to the gear assembly.

The goal is achieved by the fact that the gate is mounted on the slider so that it can be rotated and pressed against the latter by means of an additionally introduced elastic element in the plane perpendicular to the displacement of the slider.

FIG. 1 shows the boot device, general view; in fig. 2 shows section A-A in FIG. one; in fig. 3 is a view B in FIG. 1 (feed in the plan).

The grip 1 is rigidly fixed to a clamp 2, loosely mounted on the axis 3. The axles of the axle are rigidly connected to the slide 4, to which screws 5 and 6 are attached, which serve as stops.

On the base 7, which serves as a guide for the crawler, a screw 8 is fixed, which is also an abutment, and one end of the spring 9, and the other is connected to the slider 4.

The end of the screw 5 is in contact with the head of the drive lever 10 connected to the drive of the feeder, for example a cam.

A pin is installed on the gate, the head of which is in contact with the stop 12 connected with the slide.

The pressing of the gate 3 with the pin 11 against the stop 12 is carried out by the elastic element 2Q (spring) 13, the tension of which is adjusted by the screw 14.

Claims (1)

The gear wheels 15 are located in the magazine 16, and the matching wheel 17 assembled with the body of the assembled product is installed in the working position. The operation of the feeder is as follows. The gear wheel 15 falls from the magazine 16 into the nest of the gripper 1 of the nib 2 and when the driving lever 10 is rotated counterclockwise under the action of the spring 9, the slider with the gate moves in the direction of the working position. The movement of the slider is carried out along a trajectory providing tangent insertion of the feed wheel with the adjacent gear wheel of the assembled product 17 previously installed at the working position. Since the relative position of the teeth of the feed wheel 15 and the gear wheel 17 is random, their initial contact can occur either along the lateral surface of the teeth or along the tips of the teeth. In the first case, with further movement of the slider with the cracker to the working position, one or both of the wheels will rotate until the tooth of one of the wheels is in the hollow of the other. In the second case, the tooth of the supplied wheel will begin to slide along the tooth of wheel 17, turning the grip with the chuck clockwise until the tooth of the first wheel is in the hollow of the second. Then, the spike with the grips and the supplied wheel under the influence of the spring 13 will begin to turn counterclockwise, which ensures that the wheels are engaged. After the abutment of the screw 6 into the end of the screw 8, the slider stops with the hook, and the mating wheels are fully engaged. Further, an appropriate mechanism (not shown) carries out the supply of other parts of the assembled product and the connection of the wheel supplied by the gate to the details of the assembled product, for example, the body of the assembled product. The application of the invention will improve the reliability of the input to engage the mating wheels of the assembled product, i. reduce the number of failures of the assembly machine on which the boot device will be installed. Claims A loading device for feeding parts such as gears, comprising a spring-loaded slider with a slide, mounted with reciprocating mixing from a drive magazine, characterized in that, in order to increase the reliability of the device when feeding gear assemblies, the slider is mounted on the slider can be rotated and pressed to the latter by means of an additional elastic element introduced in the plane perpendicular to the movement of the slider.
