Description

 eleven

The invention relates to mechanical engineering and can be used for loading and unloading large-sized parts like box bodies in vertical boring machines.

A device for supplying parts to the process equipment is known, which contains a tray with unbalanced two shoulders and conveyor-distributor levers with lifting prisms Q.

This device has a complex design of the conveyor; a distributor, which limits its scope.

A loading and unloading device, containing feed and discharge roller conveyors with drives, clamping devices with a basic support for centering the part mounted on the movable table 2 is known.

The disadvantages of this device are the unreliability of the work of the conveyors during the feeding and unloading of large parts, as well as the difficulty of placing the parts in the jigs.

The purpose of the invention is to increase the reliability of the device.

This goal is achieved by the fact that in the loading and unloading device to a vertical finishing and boring machine containing feed and discharge roller conveyors with drives, clamping devices with a base for centering the part mounted on a movable table, feed and discharge rollers, are installed with simultaneous lifting above the base support clamping devices, and the rollers of these conveyors are placed coaxially between themselves.

I. ,

The drive of the feeding roller table is reversible, and the clamping device is provided with a restrictive stop.

FIG. 1 shows a device, a general view; FIG. 2 - the same side view; in fig. 3 - the same plan view

The loading and unloading device to the vertical boring machine contains a base 1 with a movable table 2 mounted on it, clamping devices 3 mounted on the movable table 2 and equipped with basic supports 4 and 5 for centering the parts, hydraulic 90492

roll cylinders 6-8 and clamps 9-11, a column 12 on which a platform 13 with boring heads 14 and 15 is mounted for movement, racks 16-18 mounted on the base 1, a frame 19 mounted for lifting from hydraulic cylinders 20 -22, supplying 23 and discharging 24 live rolls, associated

to respectively with a reversing drive 25 and a drive 26 and placed on the frame 19 so that the rollers are both. roller conveyors are coaxial with each other and lowered below the base supports 4 and 5 of the clamping fixtures 3 in the slots specially made for them, and the restriction stops 27 and 28, fixed respectively on the frame 19 and the clamping fixture 3.

The device works as follows.

In the initial position of the movable table 2 with jigs. MI 3 is in the machining position, the boring heads 14 and 15 are lifted up, the live rolls 23 and 24 with the frame 19 raised by the hydrocylin-drami 20-22 above the level of the base supports 4 and 5 of the clamping fixtures 3. 0,

The two parts 29 and 30 are mounted on the feed roller 23 and are moved to the loading position up to the limiting stop 28.

5, the table 2 with the clamping devices 3 is fed from the processing position to the loading position (under the fed parts 29 and 30). This is due to the coaxiality of the position of the rollers of the pickup 23 and the discharge roller 24: the clamping devices 3 pass freely in the gaps between the rollers. Frame 19 with roller tables 23 and 24, being lowered down by the action of hydraulic cylinders 20-22, allows the rollers of the feeding roller table 23 to enter special grooves in the clamping devices 3, a. Details 29 and 30 center on base pillars 4 and 5. After

0 clamping parts with tacks 9-11 under

by the action of the hydraulic cylinders 6-8, the movable table 2 is fed to the machining position. The platform 13 with boring heads 14 and 15 is lowered down and

5 performs processing of parts. During processing, the next parts are mounted on the feed roller table 23, are oriented on it by means of

The keys of the reversing drive 25 are fed to the loading position.

At the end of the treatment, the boring heads 14 and 15 are returned to the upper initial position, and the machined parts 29 and 30 are freed from the action of the clamps 9-11; The frame 19 is lifted upwardly by the action of the hydraulic cylinders 20-22, the rollers of the withdrawal roller table 24 being removed by machined parts 29 and 30 from the base supports 4 and 5.

290494

The movable table 2 with the clamping devices 3 is again returned to the loading position. After moving the machined parts up to the stop 27 5, the cycle of operation of the device is repeated.

The proposed design allows the machine to be loaded with large parts, which expands the range of application and reliability of the device.
