Description

Technical Field

[0001] The utility model belongs to the field of machine tools, in particular to a feeding device used for feeding shaft workpieces during machine tool processing. Background Art

[0002] In order to facilitate processing, the existing general shaft machine tools are equipped with a feeding device. The existing feeding device is generally composed of a machine base, a pushing device, a lifting device and a control device. The lifting device is fixed on the upper end of the machine base, and a pushing device is set on the upper end of the lifting device. The above-mentioned upgrading device is powered by a motor to enable the pushing device to rise and fall quickly. The above-mentioned pushing device includes a support frame, a horizontal cross bar, a cylinder, a support plate, a pulley frame and a servo motor. The above-mentioned support frame is composed of two supporting vertical rods and a fixed cross bar connected between the two supporting vertical rods. The center of the fixed cross bar is fixed There is a screw seat, on which a lifting screw connected to the fixed cross bar is vertically arranged, the upper end of the lifting screw is a hand wheel, and the lower end of the lifting screw passes through the fixed cross bar and is screwed to the nut. An L-shaped connecting plate is fixed to the center of the horizontal cross bar, and a through hole is opened in the center of the cross plate of the L-shaped connecting plate, and the cross plate of the L-shaped connecting plate is placed on the lifting screw between the nut and the fixed cross bar through the through hole. A cylinder is fixed on the horizontal cross bar, and a support plate is fixed on the cylinder shaft of the cylinder. The support plate is used to place the shaft-like round rod to be processed by the lifting device for transportation. The upper end of the horizontal cross bar is fixed with a leather Pulley frame, both ends of the pulley frame are equipped with pulleys, two pulleys are covered with belts, a push rod frame is fixed on the belt, the push rod frame is fixed with a push rod through a connecting plate, a servo motor that drives the pulley to rotate is also fixed on the pulley frame, and a reduction gearbox is connected when the servo motor and the pulley are fixed. At the same time, the above-mentioned support plate and the horizontal cross bar, as well as the push rod frame and the pulley frame are connected by sliding rods and slide rails. When in use, the pulley is driven to rotate by the servo motor, so that the belt drives the support plate to move to the machine tool, and the shaft-like round rod is pushed into the machine tool for processing through the push rod. However, the lifting device can only quickly adjust the height of the pallet, so the height of the pallet and the processing requirements needs to be adjusted by using a handwheel to drive the lifting screw to rotate the pallet height. However, the lengths of existing shaft materials are different. When the material length is short, such as 60 cm, the existing pallet height adjustment structure is suitable. When the length is 2.2 meters, the existing pallet height adjustment structure is more inconvenient to adjust, and the flatness of the workpiece is also difficult to guarantee because the existing one is a single-point adjustment. Therefore, the market is in urgent need of a feeding device that is easy to adjust long shaft workpieces. Utility Model Content
