Supporting plate feeding system of numerical-control scraping rolling machine

Abstract

The invention relates to the technical field of oil cylinder machining, and discloses a supporting plate feeding system of a numerical-control scraping rolling machine. The supporting plate feeding system comprises a rack, wherein guide rails are fixedly mounted on the left side and the right side of the top end of the rack, fixed frames are movably mounted at the top ends of the guide rails, andracks are fixedly mounted at the ends, close to each other, of the two guide rails; and fixed seats are fixedly mounted on sides of the back surfaces of the fixed frames. According to the supporting plate feeding system of the numerical-control scraping rolling machine disclosed by the invention, the bottom ends of the output shafts of servo motors are fixedly sleeved with the gears, the racks arearranged on the side surfaces of the guide rails and connected to the gears in a meshed mode; and when the fixed frames need to be moved, the gears at the bottom ends of the servo motors can be driven to rotate at the moment by starting the servo motors; the gears can be driven by the racks to move relative to the guide rails and drive the fixed frames to move relative to the guide rails, so thatthe influence of sliding friction on movement of the fixed frames is reduced, and therefore, the advantage of assisting movement of the fixed frames is achieved.

Description

technical field [0001] The invention relates to the technical field of oil cylinder processing, in particular to a pallet feeding system for a numerically controlled scraping and rolling machine. Background technique [0002] A hydraulic cylinder is a hydraulic actuator that converts hydraulic energy into mechanical energy and performs linear reciprocating motion (or swing motion). It has simple structure and reliable operation. When it is used to realize reciprocating motion, the deceleration device can be eliminated, and there is no transmission gap, and the motion is stable, so it is widely used in various mechanical hydraulic systems. The output force of the hydraulic cylinder is proportional to the effective area of ​​the piston and the pressure difference on both sides; the hydraulic cylinder is basically composed of a cylinder barrel and a cylinder head, a piston and a piston rod, a sealing device, a buffer device and an exhaust device. In the actual production proc...

AI Technical Summary

Problems solved by technology

[0003] The volume of the CNC scraping and rolling machine is relatively large. In the CNC scraping and rolling machine, the pallet feeding system is an important part of the CNC scraping and rolling machine. The existing pallet feeding system generally consists of two guide rails. The top of the guide rail is usually equipped with a fixed frame for fixing the workpiece, which can be moved relative to the guide rail, but in actual use, due to the sliding friction between the guide rail and the fixed frame, the friction force is relatively large and easy Leading to guide rail wear seriously affects the actual guide rail life

[0004] In actual use, due to the large amount of debris that will be generated when the workpiece is processed, these debris will more or less fall above the guide rail, which leads to the fact that the fixed frame is located on the guide rail when it moves relative to the guide rail. The debris on it will affect the relative movement of the fixed frame, causing the movement of the fixed frame to be blocked, which will not only increase the pressure of the transmission system, but also increase the degree of wear and affect the actual service life

[0005] At the same time, because the fixed frame moves on the guide rail, it will always cause friction between the fixed frame and the guide rail. However, in the existing device, there is no lubricating device for this friction to lubricate it. Usually, the guide rail is only used during regular maintenance. Partially lubricated, which will lead to a decrease in the life of the guide rail and affect the user experience
