Abstract

The invention relates to the field of mechanical assembly production, to devices for pressing on shafts of engaging parts (D) with simultaneous installation of retaining rings. The purpose of the invention is the expansion of technological capabilities, as well as increased productivity and reliability through the precise mutual orientation of the various covering and covered D. and assembly in one stroke of the pressing mechanism. A set of pressed-in D 10, 11, 12 enters the prismatic lodgement (L) 9, and the base D 14 — on L 13. The pin of the centering mechanism, swivels, presses D 14 through the mandrel 7 to the fixing stop 3. At the same time, on the outer surface of the pin all press-fit inserts are positioned. Assembling D is carried out by the pushing mechanism 2 stroke with platform 8 and L 9 lowered. Then the pin and the pressing element are returned to their original position. The mandrel 7 falls onto the prismatic L 15, and the assembled assembly onto the bracket 4. Platform 8 rises and the cycle repeats. 5 .§ (L

The invention relates to mechanical manufacturing, to devices for pressing on the female shafts. parts with simultaneous installation of locking rings.

The purpose of the invention is the expansion of technological capabilities, as well as increased productivity and reliability .10

Figure 1 shows the device in the initial position; figure 2 - the position of the mechanisms of the device when centering the assembled parts using pin and mandrel; on fig.Z - 15 the position of the mechanisms of the device after assembly; figure 4 - position when returning the press-in mechanism to its original position; 5 - centering mandrel.

The device comprises a press-in mechanism 2 mounted on the base 1, a fixing stop 3, a bracket 4 for receiving the assembled unit. The centering unit includes a pin 5, 25 mounted inside the pressing element 6 of the pressing mechanism 2 and the centering mandrel 7. Between the pressing mechanism and the locking element 13. The pin 5 of the centering mechanism pushes the shaft 14 through the mandrel 7 to the locking support 3. At the same time, the whole set of pressed parts 10, 11 and 12 is placed on the outer surface of the pin 5. Then the platform 8 together with the cradle mi lowers and the drive of the press-in mechanism 2 engages. The pressing element 6 moves the whole set coverage vayuschih parts arranged in a certain sequence on pin 5 through 7, a centering mandrel on the shaft 14. Bearings with overmolding, and the retaining ring 10 is mounted in the shaft groove. Then the pressing element 6 and the centering pin 5 are retracted, the assembled unit enters the bracket 4, and the mandrel 7 hits the prism 15. The platform 8 rises to its original position, and the cycle repeats.

Invention Formula A device for assembling parts by pressing comprising mounted on the basis of a pressing mechanism. The rum is equipped with a fixture for a ba-30 fixture for fixing the immersion gap in the form of a platform 8 with a displacement drive in a vertical plane. A platform 9 in the form of a prism for a set of pressed-on parts, s consisting of a retaining ring 10, a spacer sleeve 11 and bearings 12, as well as a bed 13 for a shaft 14, also made in the form of a prism, the Auxiliary part and the centering unit mandrel, characterized in that, in order to expand technological capabilities, as well as to increase productivity and reliability, it is equipped with a device for the assembly of assembled parts in the form of a platform with a displacement drive and zhno A gravitating prism 15 for centering 40 mounted with its lodgements mandrel 7 is spring-loaded relative to the platform 8. The device operates as follows. for assembled parts, made in the form of prisms, as well as an auxiliary prism, spring-loaded relative to the platform, the latter is mounted for movement in a direction perpendicular to the direction of pressing, the centering unit is made in the form of a pin with a conical surface at the end, and the centering mandrel is made with a conical lead-in surface and loosely mounted on the auxiliary prism. From the accumulator, using a feeder (not shown), the set of pressed-in parts enters the prismatic lodgement 9. The centering mandrel 7 is in the initial position on the auxiliary prism 15, and the base part — the shaft 14 — on the lodgement 13. Pin 5 of the centering mechanism, rotating, presses the shaft 14 through the mandrel 7 to the locking stop 3. At the same time, on the outer surface of the pin 5, the whole set of pressed-in parts 10, 11 and 12 is located. Then the platform 8 together with the cradle lowers and activates the drive of the pressing mechanism ovki 2. The pressing member 6 moves the entire set of female parts arranged in a specific sequence along the pin 5 through the centering mandrel 7 onto the shaft 14. The bearings are pressed in and the locking ring 10 is installed in the shaft groove. Then, the pressing element 6 and the centering pin 5 are retracted, the assembled unit enters the bracket 4, and the mandrel 7 hits the prism 15. The platform 8 rises to its original position and the cycle repeats.
