Abstract

A DEVICE FOR DOWNLOADING AND UNLOADING DETAILS FOR A CENTER-FREE GRINDING MACHINE, containing a magazine for parts, a supporting knife, covering the last fork, installed with the possibility of vertical reciprocating movement, a gate. The horizontal feeder is installed with the possibility of horizontal reciprocating movement, and a discharge tray located coaxially with the slide gate feeder, characterized in that, in order to improve the conditions of service, it is equipped with an additional magazine installed above the discharge tray and the mechanism for addressed removal of machined parts made in the form of a slider installed in the area of placement of the discharge tray with the possibility of vertical reciprocating movement, synchronous with the movement of There are two pushers placed on it, one of which is made in the form of a hinge mounted under the additional magazine with the possibility of fixing in the horizontal and vertical position of the finger, and the other is made in the form of a spring-loaded L-shaped lever installed with the possibility of horizontal reciprocating The movement and interaction with the part of the wall of the discharge tray is spring-loaded.

Description

Isabretenne belongs to the engineering industry and can be used when loading and unloading metalworking equipment, mainly when loading and unloading parts during plunge cutting on a centerless grinding machine.

The purpose of the invention is to improve the service conditions of the machine by providing a addressed retraction of parts, while simultaneously improving safety conditions and due to the possibility of remote selection of the first part processed after the machine changeover.

FIG. 1 shows the proposed device, a general view; in fig. 2, section A-A in FIG. one; in fig. 3 view B in FIG. one.

The device for loading and unloading parts for a centerless grinding machine includes a housing 1 on which a magazine 2 for parts 3 is installed, for example rollers for bearings, a slide gate feeder A with a window for blanks, a supporting knife 5, an emphasis 6 and a knife-covering fork 7. On The housing 1 is fixed coaxially with the slide gate feeder to a discharge tray 8 of the U-shape. A part of the wall 9 of the discharge chute 8 is made rotatable and spring-loaded, below which an inclined tray 10 is fixed. At the exit of the discharge tray 8 a rotary shutter 11 is installed, and next to it is a top-mounted shop 12 with parts 13 mounted on it. the mechanism of addressed removal of parts, having a slider 14, moved in vertical guides 15 fixed on the diverting chute 8. The slider 14 is equipped with two pushers 16 and 17. The pusher 16 is made in the form of a finger Stu fixation in the horizontal and vertikalnom positions. The pusher 17 is made in the form of an L-shaped lever installed in the slider 14 with the possibility of spring-loaded horizontal movement. A roller 18 is installed at the end of the lever. In the discharge chute 8 there is a groove for the passage of a finger of the pusher 16. The slide vane 4, the forks 7 and the slide 14 are moved interlocked with each other power cylinders.

The device works as follows.

From the magazine 2, the parts 3 enter the window of the slide gate feeder 4 (along the stream B) and then are fed to the raised fork 7, which, lowering, places the workpieces on the supporting knife 5 and the stop 6. Simultaneously with the movement of the fork 7 down, the slider 14 moves up and vice versa. The machined part 3 is raised with a fork 7 to the level of the unloading, the end face of the gate feeder 4 collides with the discharge tray 8. On the discharge tray 8, the machined parts alternately under the action of the slide feeder .4 are moved by the step size. When the valve 11 is open, i.e. removed from the cavity of the tray, and the pusher 16 is rotated to a horizontal position, the processed rollers enter the inter-operating drive or container. (This rollout address is shown

Arrow D.) From the discharge chute 8, the machined rollers 3 are fed to the magazine 12 machined parts for transfer to the next machine. In this case, the flap 11 overlaps the cavity of the tray, and the pusher 16 is mounted vertically. When the slide 1 moves upward, the pusher 16 moves the parts 3 to the magazine 12 through a groove in the tray, where the parts are held by the slam-shut 13. (The direction of movement of the parts is indicated by the arrow D). To separate the first one from the grinding wheel from the total flow of machined parts, for example, to feed the control station after a tool change, set up or re-adjust the machine, the plunger 17 is moved in the horizontal direction to the extreme right position. After that, the slider 14, moving to the upper position, by the L-shaped lever of the pusher 17, the roller 18 put on its console, deflects the spring-loaded part of the wall 9 of the discharge chute 8. Through the resulting window in the discharge chute 8 the part 3 is lowered into the inclined tray 10. (This rollout address is indicated by arrow E). The movements of the gate feeder 3, the forks 7 and the slide 14 are carried out by the power drives controlled by the distribution mechanism of the machine.
