Abstract

The invention relates to a control and sorting technique in mechanical engineering and allows for an increase in productivity due to the mechanization of the formation of a package of rings. The ring measured from both sides is pushed up to the clamp by the claws 12, clamped by a spring and hinged on the bracket 11. The shaft 9 rotates 90 ° & in one direction or another and through the friction clutch 10 rotates the bracket 11 with the clamped ring. After turning, the ring is above the rolling pin. At the approach of the bracket 11 to the final position, the pusher 14 interacts with the stop. In this case, the pusher 14 moves toward the ring, acts on the grippers 12 and releases the ring. The ring is put on the rolling pin and placed on the cradle. When the shaft 9 is rotated, the leash 19, rigidly fixed on it, acts on the rail and for each cycle lowers it onto the step, which is different for the thickness of the ring. Together with the rake, a cradle with a ring is lowered. The rail is supported on a lever hinged on frame 1. The friction clutch mounted on the lever maintains the lodgement and allows it to fall each time to a height equal to the thickness of the ring. After a set of a package of rings, the cylinder located under the lever is activated, and through the lever, it raises the rail with the rings.

Description

The invention relates to a control and sorting technique in mechanical engineering and can be used to control and sort the packing rings of tracked propulders of tractors and other tracked machines by non-flatness.

The purpose of the invention is to improve the performance of the estimates of the mechanization of the formation of a package of rings.

Figure 1 shows the proposed machine, a general view; figure 2 is a view of And figure 1; on fig.Z - section bb in figure 2; in big.4 - section bb in fig.2.

The control and sorting machine of sealing rings contains a bed 1 on which the loading mechanism 2 is installed, from which the feed device 3 controlled by the ring is moved to the measuring tables 4 where the flatness of the rings is determined.

Above the measuring tables 4, the orientation mechanisms 5 are fixed, which determine the rotation of the rings on the measuring tables 4 in the process of measurement. A flipping mechanism 6 is installed between the measuring tables 4, turning the rings to control the other side of the ring on the next measuring table 4. All the mechanisms of the automaton move from the drive 7.

Sorting uzep equipped with a gauge pickup, contains a rack 8 mounted on the frame 1. Inside the rack 8 passes the shaft 9, on which through the friction clutch 10 is fixed a bracket 11 containing hinged fasteners 12, pressed by the spring 13.

The unclamp 12 at the point of unloading of the ring is unlocked by means of a spring-loaded pusher 14, which interacts with the stop 15 at the moment when the bracket 11 completes the turn from 90 ° to one side or the other depending on which ring is being transported: suitable or useless.

The machine contains two rolling pins 16 mounted on the bed 1 at the places where the rings fed by the bracket 11 are unloaded. On the rolling pins 16c, the cradle 17 is mounted on it, which is connected to the rail 18 passing inside the rolling pin 16.

The drive of the translational movement of the bed 17 down during the making of the package of rings is transmitted through the rail 18 from the driver 19 fixed on the shaft S, and with each action of the dog 19 on the rail 18 lowers the bed 17 by an amount equal to the thickness of the ring.

The rail 18 is supported on the lever 20, which is hinged on the frame 1. In the hinged fastening of the lever 20 there is a friction clutch 21, which provides

keeping the lodgement 17 in place after lowering it by a step equal to the thickness of the ring by means of the action of the lead 19 on the rail 18.

The raising of the bed 17 after the images of the package is not on it, the ring is carried out by the cylinder 22, which acts on the lever 20. The lever 20, in turn, raises the rail 18 with the bed 17 fixed with it. The lift is carried out to a height when

5, the lower ring of the bag is slightly higher than the upper end of the rolling pin 18 for easier removal of the ring packet.

A spring-loaded returning device 23 is fixed above the lever 20, which returns the cradle 17 after removing the stack of rings to the position for receiving the first ring for the newly formed packet, while the cradle 17 is slightly below the upper end of the rolling pin 16.

5 The rotation of the bracket 11 is carried out from the actuator 7. The electromagnet 24 controls the direction of rotation of the bracket 11, and depending on the command received from the measuring tables 4, which contain

0 there are inductive sensors (not shown), a switch of the bracket 11 with the grips 12 held in it, a controlled ring s one or another side, depending on whether it is suitable or not.

5 worthless. The sorting node, equipped with a ring layout tool, forms a DZ package of rings 1 suitable and unusable.

The machine for controlling and sorting the sealing rings works as follows.

0 way.

The sealing ring 25 from the loading mechanism 2 is fed by the feeding device 3 to the measuring tables 4. The orientation mechanism 5 sets the rotation

5 rings on the measuring table 4. The ring 25, tested on one side at the first measuring table 4, is turned over by the flipping mechanism 6 installed between the measuring tables 4.

0 The ring is inverted before being fed to the second measuring table 4 to control the other side of the ring.

Inductive sensors, available in measuring tables 4 (not shown), control the flatness of both sides of the ring 25; The electronic equipment of the automaton, by reworking the signals of the inductive sensors, issues a command to the electromagnet 24, which controls the distribution of the rings to suitable or unsuitable ones.

After completing the measurement on the second measuring table 4 by the feeding device 3, the ring measured from both sides is pushed to the ring by the clamps 12, which are hinged on the bracket 11 and are constantly pressed by the spring 13.

The shaft 9, which is kinematically connected with the drive 7, rotates 90 ° to one side or the other and rotates the bracket 11c through the friction clutch 10 with the ring 25. clamped in it. The friction clutch 10 is installed for safety purposes when the machine operates.

After the arm 11 is rotated, the ring 25 clamped in it appears above the rolling pin 16. The outer diameter of the rollers 16 is somewhat smaller than the internal diameter of the ring and the rolling pin 16 has a lead-in cone. When the bracket 11 approaches the final position, the pusher 14 interacts with the stop 15, while the pusher 14 advances toward the ring 25 and acts on the grippers 12 clamped by the spring 13 and releases the ring 25. The ring 25 is put on the rolling pin 16 and is placed on the cradle 17, which as the rings are fed down, all nm,; e. with each cycle a step equal to the thickness of the ring.

The lowering of the bed 17 is carried out as follows. When hallway 9 is led, a leash 19, rigidly mounted on the shaft 9, acts on the rail 18, and for each cycle lowers it by a step equal to the thickness of the ring. Together with the rail 18, a clamp 17, on which the rings 25 are placed, is lowered.

The rings 25 coming after the measurement are formed into a bag on the cradle 17, while the ring is placed from a small height, which prevents damage to the working surfaces of the rings during sorting. The rail 18 rests on the lever 20, which is hinged on the bed 1. In the hinge there is a clutch 21, which holds the bed 17 with rings 25 and at the same time allows the bed 17 to be lowered to a height equal to the thickness of the ring each time the leash 19 on rail 18.

After dialing the complete package of rings 25, the feed is stopped and the command is given to actuate the cylinder 22, which, having overcome the force of the friction clutch 21, through the lever 20, raises 18 raises the bed 17

with the rings 25 to the upper position until the lower ring in the package leaves the rolling pin 16. At the same time, the lever 20 shrinks the return; 5; 11. The package of the rings 25 moves from the cradle 17 and is transferred to a further operation (packaging). After removal of the acting force of cylinder 22 by returning 23, lodgement 17 is lowered a little

0 below the upper end of the rolling pin 16.

8 in this position, the means for unfolding the rings of the sorting unit is ready to receive the rings 25 and form a bag of incoming rings 25,

5 The use of the proposed automaton ensures the protection of the working surfaces of the rings from damage in the sorting process by using the folding ring means in the pack, allows you to get rid of the manual operation of bag formation, to increase productivity.
