Description

(54) CHIMPER

one

The invention relates to equipment for assembly and welding, is intended to rotate products 180 from the initial position and can be widely used in various fields of engineering.

Known tilter for turning products at ISO during Assembly and welding works, containing mounted on the uprights by means of pivots pivoted from the drive frame flj.

However, the mechanical swivel frame is complex in design, therefore the tilter has a high metal consumption and requires a lot of energy.

Closest to the proposed technical result and the achieved result is a turn-over device for assembly and welding works, containing a pivotally mounted pivot frame with an axis parallel to the pivot axis of the frame on which the cradle 2 for the product 2 is pivotally mounted.

However, the rotation of the frame with the staple is also driven, which complicates the design and increases energy costs.

The purpose of the invention is to simplify the design by ensuring that the product is tilted 180 by its weight.

This goal is achieved by the fact that the angle of rotation of the rotary frame and the rotary lodgement relative to the axes of their fastening is 90, the center of the rotary frame is displaced relative to its hinge fastening on the uprights, the axis of the hinged fastening of the lodgement on the rotary frame from the side of the center of the sheet frame, with In this case, the rotary frame is spring-loaded relative to the swing frame.

FIG. 1 shows a tilter; in fig. 2 - the same, side view; in fig. 3 - position of the revolver after

0 rotation of the product by 180.

The tilter contains mounted on the uprights of the base 1 by means of the trunnions 2 pivoting by 90 frame 3.

The center of gravity of the rotary frame is displaced relative to its hinged fastening on the uprights, and on the side of the center of gravity on the frame. Installed parallel to the trunnion 2, axis 4, on which is mounted a swivel cradle 5 with clamps for product 6. On the base there is a support 7 sec. pivot arm 8, equipped with a spring. 9 and a lock 10 positioning of the lever 8. The rotation of the cradle 5 is limited by a bracket 11 and a spring-loaded lock 12 fixed on the rack 13. On the uprights 1 are fixed stops 14, which allow the frame 3 to rotate at a 90 ° angle and lock the final position 15 of the frame. The frame 3 is equipped with a stop 16 for the lodgement 5, limiting its rotation relative to the frame at an angle of 90 °. A spring 17 and a brake device 18 are mounted between the pillars 1 and the frame 2, and a spring 19 and the brake device 20 are mounted between the frame 3 and the lodgement 5. made in the form of pneumatic cylinders with free entry of air from the atmosphere. Tilter works as follows. Frame 3 is arranged horizontally to fix this position with lever 8. On cradle 5, the product is laid down and secured with clamps b. Then the latch 10 releases the lever 8, which in turn unlocks the frame 3. At the same time, under the weight of the product (gravity forces), the frame 3 and the cradle 5 are rotated, the frame 3, until it reaches the stop 14, locks the cradle 15 in this position 5 sec., The movement continues to turn, reaches the stop 16 of the frame 3 and is fixed by the locking pin 12. As a result of the successive rotation of the frame 3 and the cradle 5, the product is rotated 180 ° from the initial position. Brake device 18, 20 provide smooth turn. . After the technological operations, the product is removed from the cantop of the bed. The latch 12 release the cradle 5, which under the action of the return spring 19 returns it to its original position. Then, the latch 15 releases the frame 3, which returns to its original position, by the springs 17. Thus, the proposed technical solution ensures the rotation of the product by 180 only under the action of gravitational forces, which reduces the operating costs and the cost of the turner. The invention The tilter containing a pivotally mounted on the uprights of the base of the swivel frame with an axis parallel to the axis of rotation of the frame on which the swivel cradle with attachments for the product is pivotally mounted, characterized in that, in order to simplify the design by ensuring the product is tilted by 180 under its weight , the swivel frame and the swivel cradle are pivotably mounted 90, the center of gravity of the swivel frame is offset from its hinge attachment on the uprights, the hinge pin axis The lodgement on the pivoting frame is installed on the side of the center of gravity of the frame, while the pivoting frame is spring-loaded relative to the uprights and provided with a stop for the lodgment, and the lodgement is spring-loaded relative to the pivoting frame.
