The invention relates to transport devices for automatic lines, and may be. used in machine tools, instrument making and general engineering. The goal is to expand the technological capabilities of the conveyor by providing a change in the step of moving parts. On the base of the conveyor 1 fixed frame 2 with clamps for parts. On base 1, horizontal guides are mounted with carriage 5 connected to rod 10 of power cylinder 9. Parallel levers 7 and 8 are mounted on carriage 5, on which a movable frame 4 is pivotally mounted. One of. levers 7 has a groove 14 located along it, in which a pushing abutment in the form of a roller 11 mounted on the stem 10 is placed. At the end of the stem 10 there are two limiting stops 12 and 13 moving along it, between which a carriage 5 is installed with a gap them. On the frame 4, pushers 15 are arranged for parts moving along its length. When compressed air is supplied to the piston cavity of the cylinder 9, the rod 10 moves by an amount l ,. The roller rotates the levers 7 and 8, the frame 3 with the pushrods 15 is raised, forming a gap D between the parts 3 and the pushrods 15.

Description

The invention relates to transport devices of automatic lines and can be used, in particular, in machine tool industry, instrument engineering and general engineering.

The chain of the invention is the expansion of the technological capabilities of the conveyor to ensure the change of the step of moving parts.

1 Stepper conveyor contains fixed j eHHyro on base of fixed NJy 2, along which parts move. For example, satellites 3, moving frame, carriage 5, movably mounted horizontal eg, 6, mounted on base 1,. Frame 4 The armature levers 7 and 8, which are mounted on the carriage 5, are hinged on the carriage 5. The carriage 5 (in the power cord has a 9 cylinder). The driver is equipped with a push rod 9 mounted on the shaft of the power cylinder 9. the end of the stem 10 with the possibility of moving along his two limiting stops in vtstse regulated Faek 12 and 13.

j One of the levers 7 has a groove 14, centered along it, in which a pushing abutment in the form of a jca 1 1 is positioned 11. 4, the tappets 15 are arranged so as to be movable to its length. The frame 1 still has locks 16 for the parts.

The stepping conveyor works in a similar way.

When compressed air is fed into the piston cavity of the power cylinder 9 according to arrow a (Fig. 1), the rod 10 moves to the left by the amount and, while the roller llj acts in the groove 14 on the lever 7, rotates the latter, and together with nickname: and lever 8 to the vertical position: the upper frame 4 is raised with the stops 15: n a gap Lz (Fig. 2) forms between the stops 15 and the satellites 3 "The levers 7 and 3 turn and the upper frame is raised

4 occurs when the carriage is stationary

5 due to the considerable friction between the carriage 5 and the horizontal guides 6 until the clearance D is selected and the adjusting nut 12

It does not rest against the right end of the carriage 5. Upon further movement of the rod 10 to the left, the carriage 5 and the upper frame 4 begin to move, the gap is selected and the satellite 3 moves by a step equal to (t - w) where t is the movement of the rod 0 of the power cylinder (Fig. 2).

When compressed air enters the rod cavity of the power cylinder 9 along arrow b (Fig. 3), the levers 7 and 8 first turn, and the upper frame 4 (carriage 5 is fixed) is lowered, the gap & D is fully selected, the adjustable nut 13 abuts the left end of the carriage 5 and the latter, together with the levers 7 and 8 and the upper frame 4 with the stops 15, return to their original position.

The adjustment of the conveyor pitch is carried out by moving the lugs 15 on the upper frame 4 by changing (increasing or decreasing) the clearance D. In order to prevent satellite overshoot 3 due to inertial loads, fixing devices 16 are installed at each position (Fig. 4).

Due to the presence of a single cylinder, which simultaneously lifts the upper frame, as well as moving the carriage together with the latter, and the use of adjustable stops and clamps, the design of the step conveyor is greatly simplified and its technological capabilities are greatly enhanced by changing the step of moving parts.

Claims (3)

1. A stepping conveyor comprising a fixed frame fixed on the base, horizontal guides mounted on the base with a carriage installed in the latter, connected to the power cylinder rod, and a movable frame hinged on parallel levers, differing in that the purpose of expanding the technological capabilities of the conveyor by ensuring the change of the step of moving parts, the conveyor is equipped with a pushing pin mounted on the rod of the power cylinder mounted on the end of the rod with the ability to move along it with two restrictive stops, and pushers for parts located on the movable frame with the possibility of moving along its length, with the levers mounted on the carriage, and one of them has a groove along it the pushing emphasis is placed, at the same time the carriage installed between restrictive stops with a gap and with the possibility of alternating interaction with them. 2. A conveyor according to claim 1, characterized in that the pushing abutment is completed in the form of a roller. 3. Conveyor according to claim 1, characterized in that the fixed frame has clamps for the parts. Xt WITH Gp TU /,  V figure 1  her WITH TU L h, J  f BlidA sixteen
