SU99493A1 - Automatic loading device for machine tools - Google Patents

Description

The invention is an automatic loading device that receives a cylindrical shape with an HHOXX device reaching a continuous flow closely to each other and transmits them to the working unit.

Automatic loading devices are known for feeding cylindrical articles 1C to metal halok HiHM flocks having disc turret feeders with open slots.

The main feature of the Older device is that, for the purpose of introducing the product, P1J into the clamp I1 1 jigs, spring-loaded ones are applied; cathels located in the frame, moving up and down in the direction perpendicular to the axis of the receiving disk of the device and controlling at the end of its upward motion, after stopping the pushers loading the product with clamping devices, work of the clamping devices on the working unit .

The drawing shows a plan view of the boot device and its release.

JJb cut

The receiving disk / device mounted on housing 2 has {wiki 3 with interchangeable cylinders 4. The inner radius of the semicylinders is determined by the diameter of the products that come out of the hole is prevented by the interchangeable rim 5.

The product delivered by the trailer tangentially to disk I, gets into the loading area A of the device between the shaking-up valve 6 and the disk /. The valve 6 under the influence of the spring presses the product to the turning disk. The product, rolling over the valve, falls into the nearest in the direction of movement of the well with the half a tank and is installed in it under the pressure: the valve.

The wells are located on the periphery of the disk in groups of from one to several in each group} of groups (the figure shows two wells in the group). Depending on the number in the group, one or more items will be accepted.

The rotation of the disk is forcedly controlled through a gear transmission by dividing the table of the working unit.

hitting the well, the product is transferred by rotating the disc to zone B - the point of overload from the device to the working assembly and is pushed out of the well by the pusher 7.

The pushers 7 are in a frame consisting of the lower part 8 and the upper 9 and moving upwards in the vertical direction, receiving movement from any drive. In this case, from the hydraulic cylinder 10.

The movement of the frame, which is driven by the pushers 7 I1 of the device from the device into the working assembly, is also used to control the product clamping mechanism. At the beginning of its upward movement of the frame, pressing on the corresponding body: a lever, an electric limit switch or a hydraulic valve, gives the command to open the clamping device of the working unit. In the subsequent movement of the product frame, as indicated above, the pushers 7 are inserted into the open clamping devices and pressed against the installation stops. Then top

9, the frames and products remain fixed by compressing the spring //, and the movement of the lower frame part 8 is used to press, for example, using levers / 2 and 13.

Subject invention

An automatic loading device for cutting machines with a revolving disk feeder that periodically moves products from a continuous conveyor to the clamping fixtures of the machine, characterized in that, in order to insert the products into the clamping fixtures, spring-loaded pushers are used. reciprocating movement in the direction perpendicular to the plane of rotation of the receiving disk of the device and controlling at the end of its movement to the disk after stopping the pusher her article zagruznvschih E jig clamping operation on the operating unit.
