FIELD: mechanical assembly production, in particular, devices for disassembling connecting rod-piston-type assemblies.

The aim of the invention is the expansion of technological capabilities.

The goal is achieved by supplying the device with additional actuators ensuring the removal of stop rings with antennae.

The unit for disassembling the assemblies contains mounted on the base 1 rotary table 2 with sockets 3 for disassembling nodes 4 "Fixing clamps 5o are fixed near the sockets an additional table 8 is fixed, on which circumferentially axial slots 3 actuators 9 are mounted with the possibility of translational movement, as well as a drive of these mechanisms, made in the form of a power cylinder 10 and a pressure disk 11 Nick turntable 2 and coaxially opgyuzitno mechanisms 9 mounted auxiliary actuators actuated by the power cylinder 12 and the push bar 13 ° Drive head actuators 9, all identical in construction and each comprise a rod 14 with washers and retainers, the spring 15 and the housing 16 of

At the positions of the additional table 8, the following actuators are installed 9 „

2 "Each of these mechanisms is made in the form of a hollow body 17 mounted on a rod 14, a spindle 18 with a groove 19 at the end and a spiral groove 20 on a side surface mounted with the possibility of axial and limited angular movement in the cavity of the body 17 and spring-loaded elastic element 21 with respect to the latter, as well as the finger 22, fixed in the wall of the housing 17 and placed in the groove 20 of the spindle 18 with the ability to interact with the latter. Spiral groove 20 is located on an arc equal to 180 "Width and depth of the groove 19 respectively tstvuyut size antennae dismantled circlip 230

Positions By Mechanisms for removing locking rings j are arranged similarly to the mechanisms of their orientation,. Each of the mechanisms of removal is made in the form of a collet clamp 24 and spring-loaded kleshev grips 25 located in it, as well as stops 260

Position IIIo Here is the mechanism for removing (breaking) piston rings, made in the form of uneven blades fixed on the rod 14 (not shown)

Positions IV. Piston pin extrusion mechanism (not shown)

Positions V0 A piston reset mechanism containing a forked lever 27 connected to the stem 14 of the respective drive head.

Positions VI. The mechanism of extrusion of the sleeve, connecting rod, equipped with a mandrel connected to the rod with its drive head and a movable fork support supplied by the drive under the end of the lower head of the connecting rod (not shown)

Positions VII. The mechanism for resetting the connecting rod, similar to the mechanism installed at position V of the reset pistons (not shown)

The installation kit also includes a loading mechanism 28, trays 29 for trapping and moving parts of disassembled units and a container 30 for their accumulation

, The control of the power cylinders 6, 10 and 12 and the loading mechanism 28 in the process of disassembling the assemblies is carried out automatically by means of an air-distributing mechanism

The installation works as follows

The connecting rod-piston assemblies 4 to be disassembled, each of which includes a connecting rod, a piston, a bushing, a finger, lock and piston rings, are fed by a loading mechanism 28 into the slot 3 of the first position of the turntable 2 and fixed by a clip 5 through the hole of the lower connecting rod head

The central power cylinder 10 is turned on, which, through the pressure disk 11 and the drive heads, acts on the actuators 9, located at all seven positions of the additional fixed table 80. At the same time, the lower power cylinder 12 is turned on, which transmits the pressure and two drive heads of the lower actuator 13 mechanisms I and II positions

After actuation of the actuators, the power cylinder 6 is turned on, which, turning the table 2 on 1/7 of a circle, leads all sockets 3 with disassembled nodes to the next position. The feed mechanism of the loading device is activated and the next node is fed and fixed to the free slot 3.

During the first revolution of the table, until all the sockets are filled with nodes, as well as when there are gaps in the loading of the initial position, some of the actuators will operate idle.

Actuator orientation

circlip works as follows

When the actuator rod 14 is axially moved, the spindle 18, in contact with the antennae of the retaining ring of the disassembled assembly, begins to rotate along the helical groove and at the time of the rectangular groove and antennae move in the axial direction to the depth of the groove or until it touches the end of the piston pin and captures the antenna , rotate the retaining ring in the piston groove to a certain position, stopping when the finger 22 stops at the end of the spiral groove 20 of the spindle 18 Because the spindle's rotation angle is specified by the length of the spiral canal then the turn of the locking ring behind the antennae always ends in one position

This ensures that the antennae are oriented to grip and compress. Removing the ring by another actuator at the following position. When the actuator 14 returns to its original position, the spring 21 pushes the spindle 18, which rotates along the helical groove in the opposite direction to its original position. At position II, the clamp mounts 25 of the ring removal actuator are inserted piston bosses, seize the antennae of the locking ring and 5 when moving in the opposite direction, the collet clamp compresses the grippers and removes the ring from the groove. When the gripper is released, the ring falls out

Orientation and subsequent removal of the locking rings are carried out simultaneously on both sides of the piston by upper and lower actuators.

Next, at subsequent positions, technological operations are carried out to remove the piston rings, press a finger out of the piston bosses, reset the latter with a fork lever 27, and also press out the sleeve and the upper connecting rod head. At position VII, the fixing clamps 5 release the lower connecting rod head and produce it dump in tray 29
