Description

(54) DEVICE FOR MOVING CYLINDRICAL PRODUCTS TO THE MACHINING MACHINE

one

The invention relates to industrial transport, namely, devices for moving cylindrical articles to processing machines.

Arrangements for moving cylindrical articles are known, comprising a frame on which load carrying rollers mounted at an angle are mounted. For the rotation of products between the load-carrying rollers, drive rollers are mounted, fixed in rocker arms, having figured cuts interacting with clamps 1.

This design of the device is complex and does not protect the load carrying rollers from shock loads.

It is also known a device for moving cylindrical articles to machining machines, comprising a support frame, mounted on the working load carrying rollers and vertical stands with a fixture fixed on them, ensuring the combination of the longitudinal axis of the product with the axis of the machine cartridge. The device is made in the form of equal-shoulder levers mounted on the frame symmetrically to the axis of the machine chuck. The levers have the ability to rotate in a vertical plane by means of a power cylinder connected to one of the levers 2.

The disadvantage of this device is that it also does not protect

5 load-carrying rollers from shock loads, which reduces the reliability of the device. The purpose of the invention is to increase the reliability of the device for moving cylindrical products to the processing machine.

10 This is achieved by the fact that the vertical posts are mounted with the possibility of vertical movement with the help of a ram and provided with a receiving frame for products rigidly attached thereto, the said device for combining the axes of the product and the machine chuck made in the form of a pressure roller rigidly connected with The vertical support and the load-carrying rollers are mounted on the support frame by means of spring-loaded levers swiveling in the vertical plane.

FIG. 1 shows the proposed device, a general view, in front; in fig. 2 is a view A of FIG. one; in fig. 3 shows a section BB in FIG. 2. The device comprises a support frame 1, on which pivot arms 2 are mounted, connected with spring shock absorbers 3. Load-carrying rollers 4 are fixed on the levers 2. Vertical columns 5 are mounted on the frame 1, which have the possibility of vertical movement in the guides 6 with frame 1. Racks 5 are rigidly attached to the receiving frame 7 and the beam 8, on which the pressure roller 9 is mounted. On the supporting frame there is a beam 10 attached to which the power cylinder II attached to the struts is attached. The load-carrying 4 and pinch 9 rollers contain disks 12 mounted in the housing 13 and having the possibility of rotation in a plane perpendicular to the longitudinal axis of the cylindrical article 14 transmitted to the machine (not shown in the drawing). The circumference of the disk 12 is fixed fingers 15, rigidly connected to the axes 16, on which the sleeves are placed 17. The sleeves with their surface fit along the disk contour and have the ability to rotate in a plane parallel to the direction of movement of the products 14. The fingers, axes and sleeves of opposite disks are shifted relative to each other. On the beam 8, an adjusting screw 18 is installed, by means of which the necessary stroke for clamping products is set. The device works as follows. The cylindrical article 14 is loaded, for example, with a pushrod (not shown) onto a receiving frame 7, which, under the action of the power cylinder 11, together with the beam 8, the pressure roller 9, the legs 5 and the beam 10 moves downward, placing the product on the rollers 4. The presser roller, lowering down, presses the product 14 and expands the rollers 4 until the end of the adjusting screw 18 rests on the frame 1. At the same time, the levers 2 rotate and the axis of the product is aligned with the axis of the machine chuck. Longitudinal movement of the product is ensured by the rotation of the sleeves 17 relative to the stationary axes 16. The rotation of the products around its axis during processing is provided by the disks 12 rotating relative to the stationary housing 13. The proposed device design protects the load-carrying rollers from shock loads, which increases its reliability . At the same time, the constant axis of rotation of the product is maintained. The formula of the invention A device for moving cylindrical products to a processing machine, comprising a support frame, load carrying rollers mounted on the frame and vertical posts with a fixture mounted on them for aligning the longitudinal axis of the product with the axis of the machine cartridge, characterized in that, in order to increase reliability devices, vertical posts are mounted with the possibility of vertical movement with the help of a power cylinder and are equipped with a receiving frame for products, rigidly attached to them; The tool for aligning the axes of the product and the machine chuck is made in the form of a pressure roller rigidly connected to the vertical upright, and the load-carrying rollers are mounted on the support frame by means of spring-loaded arms that pivot in a vertical plane.
