Description

The invention relates to general mechanical engineering, assembly production and can find application in the production of drive sleeve-roller chains, in particular, for orientation and stacking of cylindrical bushings mainly with a basing element along the longitudinal joint seam.

A device is known for orienting cylindrical can bodies (US Patent No. 2140246, Class 198-33 of 12.13.38), in which the body is rotated using two rotating rolls, it is stopped in a predetermined position by means of a probe inserted into the body and sliding on the surface of the case until the seam of the can, which acts as a base element, rests against the probe.

The use of such an orientation mechanism is not adapted to cylindrical parts with a small inner diameter, which does not allow the probe to be inserted inside.

A device is also known for orienting parts with a recess (USSR Author's Certificate No. 1284780, class B 23 Q 7/08, 1987), in which cylindrical parts with axial recesses are fed along the feed tray to the orientation position of the needle-shaped stop and the rotating roller. The part, drawn to them by the inertia forces arising from the oscillation of the tray, is rotated by the roller until the emphasis is combined with the recess. Having lost support on the stop, the part shifts from the roller to the side of the stop, then, slipping from the stop, enters the recess in the profile guide and is transported to the pick-up position by the gripper of the robot.

The use of such a mechanism is not always technologically and structurally possible, especially for small parts such as a roller chain sleeve.

The closest in technical essence is the "Lever loading device" (Artobolevsky II Mechanisms in modern technology. Volume 1. M., 1970, p. 258) for laying cylindrical parts, consisting of a slide fixed rigidly with the tube , and a lever fixed rigidly with a flap rotating around an axis. When moving the slider along the guides downward, the lever, in contact with the stop, is rotated around the axis, while the shutter moves away from the tube, and the workpieces are loaded into the feeding device. When moving the slider up, the lever and the shutter under the action of the spring take their initial position, closing the exit from the tube, which is again filled with blanks. There is also a latch for fixing the position of the lever.

However, the known device does not provide when laying the orientation of the bushings with the base element.

The technical task is to expand the technological capabilities of the lever loading device for performing operations of laying and orientation of the bushings with a basing element. Such an element, in fact, can be holes of any shape, convexity, concavity.

The essence of the invention lies in the fact that the laying of the convoluted sleeve to a position occurs in an oriented state relative to the joint of the joint. In a device for laying and orienting cylindrical bushings mainly with a base element comprising a housing — a tube and a spring loaded lever clamp, the housing is additionally equipped with a spring loaded needle for detecting and fixing the sleeve along the bases located along the joint of the joint, as well as a rotating roller for rotating the sleeve at the time of search base.

The introduction of a mechanism for detecting and basing on the outer surface of the sleeve into the lever loading device allows you to solve the technical problem of laying and orientation of the bushings mainly with a basing element.

Figure 1 shows a device, a section; figure 2 is a section along aa in figure 1; figure 3 shows examples of parts intended for orientation and laying in this device.

The device consists of a housing 1, a clamping lever 2, which has the ability to rotate around axis A and spring-loaded with a spring 3. The roller 4 rotates the sleeve 5 from the independent drive 6 at the time of searching for the technological element with a needle 7, spring-loaded 8. The stop 9 serves to limit the position of the lever 2 .

In the upper position of the housing 1, the lower sleeve is secured against falling out by the spring clip 2, and the previous sleeve 5 is rotated by the roller 4 until the spring-loaded needle 7 locks it against rotation. Then, when moving the housing 1 downward, the roll 4 is forcibly forcibly withdrawn first, then the needle 7, the lever 2 is on the stop 9, rotates about the axis A and releases the lower sleeve. The next sleeve 5 gets to the lower position and then, with the upward movement of the housing 1, it is fixed by the lever 2. The roll 4 and the needle 7 are brought in, the cycle is repeated.
