Description

one

The invention relates to assembly equipment and can be used when assembling elevator bar blades on an assembly chain conveyor, in particular, for lintel pins.

The following devices are known: for splintering the rods of the elevator web comprising a frame, prisms for rods, bases of fc guides in which the mandrels with the cotter pin are mounted, and an actuator 13.

However, the known device does not ensure the continuity of the shplintovi rods, which reduces the productivity of the process.

In order to improve the performance of the spline, the device located on the assembly conveyor contains blocks of chain gears located along the sides of this conveyor, to the plates of the chains of which rigidly attached strips are mounted on them with the possibility of longitudinal reciprocating movement.

the distance between the axes of adjacent mandrels is equal to the pitch of the prisms fastened to the plates of the assembly conveyor.

The mandrels are equipped with gears, and in the frame are mounted the slats, which form rack and pinion gears with these gears.

In addition, copiers are made in the frame, and each 9th foundation is equipped with a roller, which interacts with a piston.

The drive sprockets of the chain drive units are kinematically associated with the drive of the assembly conveyor.

FIG. 1 is a diagram of the described device; in fig. 2 - the same plan view; in fig. 3 shows section A-A in FIG. 2; in fig. 4 shows a section BB in FIG. 2; in fig. 5 shows a section B-B in FIG. 3; in fig. 6 - section G-Y in FIG. 3; in fig. 7 shows a dd in fig. 3; in fig. 8 is a section E-E of FIG. four; in fig. 9 - shplinggovatel in the initial position; in fig. 10, section JF in FIG. 9; on fng. 11 cotter pin, at the end of the operation are flexible cotter pin. The device is located on traction chains of a continuously operating assembly conveyor 1 equipped with prisms 2 for accommodating the rods 3 of the assembled alevatry fabric (Figs. 1, 2 and 8). The ends of the rods have flats a (Fig. 7), which mate with curly ropes made in the outer plates 4 of the drive chains 5 of the assembled elevator web. On the side of the assembly chain conveyor, there are two blocks of 6 chain gears, to the brackets 7 of which (Fig. 3) the strips 8 are rigidly fixed with guides in the form of a dovetail. On the slats 8, the devices are installed with the possibility of longitudinal reciprocating movement of the base 9 (Fig. 5) with through guide holes for mandrels 1O, having the possibility of performing a rotational movement. Each mandrel 1O is equipped with gear 11 and has a prismatic shank 12, on which the head 13 with a pin is freely mounted. The spring 14 constantly presses the head 13 to the shoulder 15 of the tailcoat 12. The distance between the two adjacent mandrels JO is equal to the step of the prisms 2. A rack 17 is rigidly attached to the frame 16, forming 11 gears with gears with gears. On the axis, attached to the base 9, the rollers 18 are mounted (Fig. 3 and 6), interacting with the curvilinear groove 19, made in the frame 16. On the shaft 2O (Fig. 3) drive sprockets 21 for the chains of the blocks 6 are rigidly mounted. , and on the shaft 22 - asterisks 2. for the pull chains of the assembly conveyor 1 (Fig. 2 and 4). An asterisk 24 is also rigidly mounted on the drive shaft 22, which is connected with an asterisk 25 equal to the number of teeth, 25 sitting on the shaft 2O, with a roller-roller chain 26. The connecting shaft 22 is kinematically connected to the electric drive 27 via a gearbox 2 by a chain transmission 29. On the straight working sections of the chains of the blocks 6, the axes of the mandrels 10 coincide with the axes of the rods 3 installed in the prisms 2. The device for pinching the elevator rods, the web operates as follows. The prisms 2 are constantly moving assembly chain (wirelines 1 lay rods 3, on the ends of which, in a certain sequence, insert the outer and inner plates of the 4 drive sleeves and roller chains 5 of the assembled elevator web, and insert the lashings 30. In the process of longitudinal, progressive movement of the chains of blocks 6 on the straight working sections of the track, the rollers 18, moving along the curvilinear groove 19 of the copier, transmit to the base 9 a forward-access movement, and the gear 11, which engages with the rack 17, communicates the mandrel 10 and the rotational movement. Thus, on the straight working section of the path, the head 13 with the pinch makes a complex movement: progressively (forward) before interacting with the cotter pin, a rotary motion, during which the bending of the ends of the PO, and again progressive, (backward) until the end of interaction with the end of the bar. The length of the straight section of the working path of the chains of blocks 6 corresponds to the length of the curved groove 19 (Fig. 6), while the distance Ej corresponds to the entry of the rollers 18 into this groove, Bg - to the translational movement of the mandrels 10 along the groove prior to the beginning of the interaction of the heads 13 with the locking pins DZ (Fig, 9 and Yu), g - to stand in the process of bending the ends of the linch pins 30 ( Fig. 11); Vd - to the outlet of the heads 13 from contact with the rods 3; The springs 14 perform the role of compensators in the cases; The possible deviation of the "7" is not the size of the length of the rod 3 and the distance from its end to the axis of the hole for the cotter pin 30, Claim 1. An apparatus for the cotter pins of an elevator belt, for example, on an assembly conveyor containing a stand, prisms for rods, the base with Yushigig in which are installed mandrels with shplinovatel and drive, is different from the fact that, with an increase in productivity, it contains located in the distance sides of the assembly conveyor blocks of chain gears, to which plates the chains are rigidly attached with installed on them with the possibility of longitudinal-. of the reciprocating movement of the foundations, (and the distance between each of the adjacent mandrels equals the pitch of the prisms fastened to the plates of the assembly conveyor. 2, The device according to claim 1, about tl and teaScenes so that the mandrels are equipped with gears, and in the frame are mounted rails that form gear-rack drives with these gears. . 3.
