SP

The exemption relates to mechanical engineering, namely, semi-automatic machines for the assembly of radial bearings with cylindrical rollers. The closest technical solution is a semi-automatic machine for assembling radial bearings with cylindrical rollers, containing a bunker device having a carriage with holes for rollers, installed with the possibility of reciprocating movement, a device for mounting the rollers into a assembled bearing, including a housing with rollers, a mechanism for sending rollers to a separator, having axles mounted on an axis with the possibility of interaction, and a spring-loaded movable sleeve, a device for crimping with a separator, having to accommodate the outer ring of the support, a punch fungus with a stop fixed on it, a pneumatic cylinder with a piston and a rod, and a control system I. The drawbacks of this device are complex kinematics and unreliability of work, as well as its low productivity, since charging of the rollers of the ring with the separator and two bends of the pneumatic cylinder are used to crimp the antennae of the separator with crimping. The purpose of the invention is to increase the productivity of the bearing assembly. This goal is achieved by the fact that in a semi-automatic machine for assembling radial bearings with cylindrical rollers, containing a bunker device having a carriage with holes for rollers, installed with the possibility of reciprocating movement, a device for mounting the rollers in the assembled bearing, including a housing with channels for rollers , a mechanism for sending rollers to a separator, having on-axis interaction between the tabs and a spring-loaded movable sleeve, a device for crimping the separator, and the fungus-punch with a stop fixed on it, accommodating the outer ring of the bearing, a pneumatic cylinder drive with a piston and a rod and a control system, a device for crimping the separator mounted on the pneumatic cylinder stem with the help of a grio punch stop with a spring-loaded movable sleeve of the rollers placed in the housing of the device for mounting the rollers. Such an embodiment of the device provides an increase in the productivity of the support assembly by folding the antennae of the separator in one stroke of the pneumatic cylinder. FIG. 1 shows the proposed semi-automatic, general view; in fig. 2 and 3 - various moments of the work of the semiautomatic device; in fig. 4 shows section A-A in FIG. 3; in fig. 5 is a section BB in FIG. 3. A semiautomatic device for assembling radial bearings with cylindrical rollers contains a hopper device 1, having a carriage 2 with holes 3 for rollers 4, mounted for reciprocating movement, a device for installing rollers 5 into an assembled bearing, including a housing 6 with channels 7 of the rollers, a mechanism Beam rollers 8c separator 9, having on its axis 10 with the interaction of the tabs 11 and a spring-loaded movable sleeve 12, a device for crimping 13 of the separator 9, which has to accommodate ruzhnogo bearing ring 14 fungus-punch 15 mounted thereon stop 16, the drive in the form of a pneumatic cylinder 17 with porschnem schtokom 18 and 19 and 20. Semi-automatic control system for assembling radial cylindrical roller bearing operates as follows. The bowl of the bunker device 1 is loaded by the rollers 4 and the electric motor is turned on. The carriage 2 performs a reciprocating motion, lifting up through the gearbox, crank, connecting rod and lever, and down, falling under the weight of the rollers. The rollers fill the holes 3 and the channels 7 of the housing and are held by the tabs P. On the support of the crimping device 13, we install the separator 9 with the outer ring 14 of the bearing to be assembled and press the start button. At the same time, air from the diffuser enters the lower cavity of the pneumatic cylinder 17 through the throttle and the piston 18 with the rod 19 goes up, raising the cup and the support of the crimping device 13 with the separator 9 and ring 14 by means of a bracket and spring. there they stop along with the support and the glass. The rod 19 continues to rise, compressing the spring. The stop 16 lifts the movable sleeve 12, squeezing the spring, and under the action of the coiled ring springs, the tabs 11 move toward the center and the rollers fall on the support (as shown in Fig. 2). Continuing to rise, the fungus 15 with its body spreads the legs 11 and the lower row of rollers pushes them into the windows of the separator 9 and the treadmill of the ring 14, the passage between the teeth of the comb. With a further rise, the fungus 15 with its petals bends the antennae of the separator 9, makes pressure testing, and the moldings of the support 16, shifting toward the center, pass into the opening of the movable sleeve 12 (as shown in Fig. 3). The stop 21 presses the limit switch 22, and the air from the diffuser enters the upper cavity of the pneumatic cylinder 17. The piston 18 with the rod 19 is lowered and under the action of the spring-down spring the movable sleeve 12 lowers and keeps the legs 11 in the extended state. The glass with the support for the crimping device 13 and the pressed separator with rollers and a ring are held down by the spring, and the fungus 15 is removed by the descending rod 19 from the pressed separator 9. Lowering to the bottom of the glass, the fungus 15 with the glass, the support for the pressing and the assembled bearing block later lowering the cylinder rod 19 returns to its original position. When the support for the crimping device 13 with the assembled bearing unit is lowered, the rollers in the housing channels 7 are lowered onto the tabs 11 and held by them.

Due to such a semi-automatic assembly of bearings with cylindrical rollers, its productivity is increased by using two double strokes of the pneumatic cylinder.
