Abstract

The invention relates to mechanical production and can be used to assemble connecting rods with pistons and internal combustion engines. The goal of the brevity is to expand technological capabilities by assembling thin-walled male parts. The device contains a base 1, on which the feeding mechanisms, installation and centering mechanisms of the male part (OD) 6 are mounted with one another pushing rod (TSH) 13 and centering rod (TSR) 14 with the drives 15, 16 located coaxially and opposedly. the shock effect is made in the form of a slider 19 with the striker eccentrically fixed at its end. TSH 14 is made in two stages, and TSH 13 is equipped with a support heel that has the ability to interact with the butt of a small stage of TSH 14, the length of which is longer than OD 6. After the introduction of TSH 14 into OD 6, the drives 24 and 15 are simultaneously turned on and the rotation mechanism moves shock effect. In the process of operation, the striker of the slide 19 changes the place of its contact with the OD 6 around the circumference of the latter, making an oscillatory motion, as a result of which assembly occurs. When installed in an aperture of the first TS 13, it rests on the small step of the central clearance station 14 and is ejected. 6 Il. (Ls

Description

The invention relates to the mechanical assembly production and can be used, for example, for assembling rods with pistons of internal combustion engines.

The aim of the invention is the expansion of technological capabilities through the assembly of thin-walled male parts.

The assembly device comprises mounted on base 1, including a C-bracket 2, feeding mechanisms for assembled parts (not shown), lodgements 3, 4 and 5 for these parts. The cradle 3 is designed for the male part (finger) 6. The cradle 4 and 5, intended respectively for the piston 7 and the connecting rod 8, are installed with the possibility of an adjustment movement in the direction the pen

The installation axis is spring-loaded, and spring-loaded with respect to the base 1 by elastic elements 9 and 10. The position of the bed 4 is adjusted with the screw 11, and the bed 5 with the screw 12. The device also includes an installation and centering mechanism that includes axial movement coaxially and oppositely one another hollow pushing 13 and centering 14 rods connected by q drives of their movement 15 and 16. Centering rod 14 is made in two stages, where the diameter of the small stage is smaller than the inner diameter tra, and the length is greater than the length of the male part (finger) 6; the pushing rod 13 is provided with a support pin 17. From the side of the pushing rod 13, a guide die 18 is fixed to the bracket 2.

The mechanism of rotational impact on the end of the finger 6 is made in the form of a slider 19 with eccentrically fixed at its end facing the lodgings, briskly 20 and diametrically through hole at the other end, in which axis 21 is installed, copier 22, rollers 23 placed at the ends axes 21c with the possibility of free rotation and interaction with the cam 22, and also the rotation actuator 24. The slider 19 is installed in the cavity of the pushing rod 13 coaxially with the latter and they have the possibility of joint rotation; In addition, the slider 19 has the ability to make reciprocating movement and is spring-loaded in the axial direction by the elastic element 25. The copier 22 is mounted on the end of the pushing rod 13 facing the drive of its translational movement and fixed to the housing 26, which is connected to the movement cylinder cylinder 15. With a rotation drive 24, the slider 19 is connected by a clutch 27,

The device works as follows.

From the accumulators by the feeding mechanisms in the oriented position, the striker 8 is placed in the cradle 5, the piston 7 - in the cradle 4, and the finger b - in the cradle 3.

A two-stage centering rod 14 is inserted into the piston 7 and the connecting rod 8. When it is inserted, the bores of the piston 7 and the piston head of the connecting rod 8 are aligned along the assembly axis, i.e. common axis coaxially

the installed centering rod 14 and the guide die 18. After insertion of the rod 14, the rotational drive 24 of the punching mechanism of the rod & rod 10, equipped with the fifth, and its actuator 15 is simultaneously activated, while the piston pin 6 is inserted into 18, the rotation through the sleeve 27 is transmitted to the pushing rod 13 with the slider 19, while the rollers 23 planted on the axis 21 roll around the profile of the stationary copier 22. By means of the copier 22 and the spring 25, a pulsating reciprocating displacing a small amplitude of the slide 19 relative to the pushing rod 13. In addition, during the assembly process, a constant pressing of the piston pin 6 occurs in the direction of its insertion into the piston 7

push rod 13 og pivoda 15. When rotating the push rod 13 and the slide 19, the striker 20 changes its contact with the finger 6 around the circumference of the latter. Thus, an oscillating oscillating movement of the end of the piston pin 6 occurs and, in combination with a constant pressing with its pushing rod 13, the connecting rod-piston assembly is provided. When a thin-walled pin 6 is inserted into the hole, the first 17 of the pushing rod 13 rests on the small step of the centering rod 14 and is ejected. Since the length of the small step of the centering rod 14 is longer than the length of the finger 6, the inner diameter of the finger is prevented from landing on the chamfer of a larger stage of the centering rod 14, which eliminates jamming, thus due to the changed pushing structure 13 and

centering 14 rods can be assembled thin-walled parts,
