Abstract

The invention relates to the application of coatings by chemical and electrochemical means and can be used in the instrument-making and engineering industries. The aim of the invention is to increase productivity, increase reliability and service life. During the horizontal movement of the auto operator, the sprockets 12 and 13 of the drive 11 are simultaneously synchronized. As a result, the vertical movement chain 14 and the automatic operator horizontal movement chain 15 move at the same speed and therefore does not shift the chain relative to the block of stars 5, which does not cause its rotation, and the carriage 3 is in place. With the vertical movement of the carriage 3, only one sprocket 12 is rotated. Thus, the proposed technical solution will increase the speed of the auto operator by eliminating the system of blocks through which it is necessary to pull the cable of the vertical movement of the carriage. 1 hp f-ly, 2 ill.

The invention relates to the field of chemical and electrolytic coating and can be used in the instrument-making and (engineering industry).

The aim of the invention is to increase productivity, increase reliability and service life.

FIG. 1 shows the general scheme of an auto operator with a drive; in fig. 2- drive diagram of the auto operator.

The auto operator consists of a frame 1 with tubs along which the column-Hci 2 is fixed, in the guides of the last carriage 3 is installed. In the upper part of column 2 there is an asterisk k, and in the lower part there is a block 5 of stars. Chain 6 is attached to the carriage 3, slung over the sprocket 5 of the block 5.

In the lower part of the frame 1 there are sprockets 7. The auto-operator moves along the rails 8. Inside the guide, sprockets 9 and 10 are installed on one side, and the auto-operator's drive 11 is installed on the other side, equipped with two output sprockets 12 and 13. Through sprockets 9 and 13 pass through chain 14, and in the auto-operator the chain through Star-Daughters 7 is thrown over the sprocket of block 5. Through the asterisks 10 and 13 Passes through chain 15, with the ends of the chain rigidly connected to frame 1 of the auto-operator. The guides 8 auto-operators are installed along the baths 1b.

The actuator 11 of the auto-operator consists of an electric motor 17 connected to the shaft 18, on which a screw is mounted, a conical coupling half 19 and a sliding gear 20 with cones. Parallel to the shaft 18, there is a shaft 21 on which there is a screw and a gear wheel 22 meshed with gear 20. The screws are engaged with the worm wheels, the worm wheel 23 is fixed on the shaft 2k, and the wheel 25 on the hub 26 The shaft 2k passes through the hub 26. Sprockets 13 and 12 are attached to the hub 26 and shaft 2k, respectively. The drive housing is provided with a pneumatic device 27 for switching on the worm pair with an asterisk 13 fixed to the hub.

The auto operator works as follows.

The horizontal movement of the auto-operator along the guides 8 is carried out with simultaneous synchronous rotation of the sprocket 13 and 12 of the drive.

11. For this, the sliding gear 20, with its cone, engages with the cone of the coupling half 19 fixed on the shaft 18. In this case, the rotation from the engine 17 is transmitted via a worm gear pair consisting of a worm gear and a worm gear 23 to the shaft 24, on the end of which the asterisk is rigidly fixed

12. Simultaneously, rotation through the coupling half 19, a cylindrical pair consisting of a sliding gear 20 and a gear wheel 22, is transmitted to the shaft 21 and then through a screw pair, (consisting of a screw and a worm gear 25, to the hub 26, at the end of which the asterisk is rigidly fixed

13. Thus, the sprockets 13 and 12 rotate synchronously, and as they rotate, the vertical movement chain k of the carriage 3 and the automatic operator horizontal movement chain 15 move at the same speed, and the automatic operator moves along the rails 8. The chain 15 moves at the same speed as the automatic operator, therefore, the chain does not move relative to the block of 5 stars, and the asterisk does not rotate, the carriage 3 stands still.

The vertical movement of the carriage is carried out with a single working sprocket, and the second asterisk, connected to the chain of horizontal movement of the frame, must be fixed. For this, the sliding gear 20 with the aid of the pneumatic device 27 is displaced to the left and its cone is fixed in the cone of the housing, the worm gear 25 and the sprocket 13 do not rotate. The horizontal displacement chain 15 is immobile, the frame 1 of the auto-operator stands still.

The rotation from the engine 17 of the drive 11 is transmitted through a worm pair to the shaft 2k passing through the hub 26. The asterisk 12 on the shaft 2k rotates, moving the vertical chain k. movement. When moving the chain k, the block 5 starts to rotate the sprocket; in this case, the chain 6 is thrown over the block 5 and the asterisk k, receives translational motion
