(54) BAR TREATMENT DEVICE

(57) The invention relates to a machine tool industry. The object of the invention is to simplify the design and expand the technological possibilities. This is achieved by placing the axis of the bar loading zone coaxially with the axis of processing the blanks. The device comprises a housing 1. a magazine 3, guides 5 designed for

feed rod 12, placed in the spindle 15 collet clamp 16 and the pusher 20. The guides 5 are made in the form of a pipe and mounted coaxially with the spindle 15, the axis of which is placed vertically. The collet chuck 16 is provided with a sleeve 18 installed in the collet with the possibility of engagement with the spindle 15. At the end of the collar 18. facing the clamping surfaces of the collet, there is a spherical surface 19 designed to interact on the collet with an internal conical surface 30. The pusher 20 is installed with the possibility interaction with the copier 25 placed into the device and placed on the housing 1. 2 Il.

FIELD: machine tool industry.

The aim of the invention is to simplify the design and expand the technological capabilities by placing the axis of the bar loading zone coaxially with the axis of processing workpieces.

Figure 1 shows the device, a general view; in FIG. 2, node 1 in FIG.

The bar processing device comprises a housing 1, a central shaft 2 on which a magazine 3 is installed with intake bodies A, under which are mounted the guides 5, the drum 6 with the working blocks 7 arranged coaxially with the guides 5, the rotation drive for performing technological operations consisting of a gear 8 and a gear 9 mounted on the shaft 10, a gear 11 of the rotational drive of the device. The piece output of the workpiece 12 is carried out using flexible belts 13 and 14. The work unit 7 consists of a spindle 15 meshing with a gear wheel 9, a collet 16 spring-loaded relative to the spindle 15 spring 17, a sleeve 18 with a spherical end 19 , a pusher 20 with a central hole 21 spring loaded 22 relative to the sleeve 23 with a roller 24 controlled by a copier 25. A rolling bearing 26 is mounted between the pusher 20 and the collet 16. The sleeve 18 is rigidly connected by means of fingers 27 with a spindle 15. On the drum 6 above block workers Me 7 can be equipped with tools for performing technological operations, for example, a cutter 28 for grooving the groove. Under the drum 6, a stop 29 is mounted on the amount of overhang 12, representing a sector and holding the products until the collet 16 is clamped. An inner conical surface 30 is formed on the collet 16. It interacts with the spherical end 19 of the sleeve 18. Receiver 31 is mounted under the drum 6 to collect the processed products .

The device works as follows.

Products 12, seized by intake bodies 4, are fed into guide 5,

single delivery of which is carried out by flexible belts 13 and 14. Next, the product 12, cut off from the flow, passes through the central hole 21 of the pusher

20, the sleeve 18, the collet 16 and abuts against the stop 29. When the drum 6 is rotated, the copier 25 moves the pusher 20 downwards, which through the bearing 26 acts on the collet 16, causing it to close. The spring 22 compensates for the excessive movement of the sleeve 23 in order to avoid the damage caused by the rigid transfer of movement. The spring force must be greater than the force of the collet 16. After the collet 16 is closed, the product 12 receives rotation and is machined, for example, the groove is grooved by the cutter 28. After the processing is completed, the cutter 28 is retracted (the cutter feed and retraction mechanism is not shown); 20, the collet is returned to its original position by the action of the spring 17 and is forced to open when the spherical surface 19 interacts with the inner

a conical surface 30. The article 12 falls into the receiver 31. The operation cycle repeats.
