Description

Technical Field

[0001] The utility model relates to the technical field of cutting processing, in particular to a cutting protection device. Background Technique

[0002] Metal processing cutting is inseparable from various equipment used in machining. It is a forming method for removing materials in the metal forming process. As one of the most widely used metal processing equipment, lathes are very common in daily production.

[0003] As one type of lathe, vertical lathes are usually used to process large-sized metal parts. When cutting metal parts, a large amount of metal chips will be generated when the cutting tool contacts the workpiece. Driven by the vertical lathe, these chips will fly out in all directions, and the flying metal is likely to cause accidental injuries to the surrounding operators. Content of the Utility Model

[0004] In view of the problems existing in the prior art, the utility model discloses a cutting protection device. The technical scheme adopted is as follows: it includes a lathe base, a workbench, a workpiece placement table, a rear gantry, a lifting frame, a moving frame, a tool mounting part, a side fixed shaft I, a side fixed shaft II, a side spring, a side mounting block, a side limiting plate, a side protection, a front through groove, a mounting structure, a front protection plate and a locking structure. The upper surface of the lathe base is the workbench, and the center of the workbench is the workpiece placement table. The rear of the workbench is fixed with the rear gantry. The front of the rear gantry is installed with the lifting frame by means of a lead screw motor. The front of the lifting frame is grooved, and the moving frame is installed in cooperation by means of a lead screw motor therein. The bottom of the moving frame is the tool mounting part. The above structures are all common structures of vertical lathes and are common equipment. Both the left and right sides of the workbench are fixed with the side fixed shaft I and the side fixed shaft II. The workbench is fixed with the side spring. The side spring is integrally sleeved outside the side fixed shaft I. The side mounting block is movably sleeved with the side fixed shaft I and the side fixed shaft II, and its lower surface is fixedly connected with the side spring. The left and right sides of the lifting frame are integrally formed with side limiting plates, which are in contact with the top surface of the side mounting block. That is, under the combined action of the side spring and the side limiting plates, the side protection connected to the inside of the side mounting block can be in a definite position. A through front through groove is opened in the front of the workbench. The front protection plate is installed on the lathe base through the installation structure. The front protection plate extends out from the front through groove. The front protection plate is provided with a locking structure. When the equipment is not in use, the front protection plate can be retracted into the front through groove through the locking structure for placement, which is convenient for loading and clamping the workpiece.

[0005] As a preferred technical scheme of the utility model, the side protection includes a connecting rod and a side baffle. The inside of the side mounting block is integrally formed with a connecting rod. The end of the connecting rod is fixedly connected with the side baffle. The front of the side baffle is integrally formed with a front limiting plate.

[0006] As a preferred technical solution of the present utility model, vertical side slots penetrating through are opened on both the left and right sides of the workbench. The positions of the side slots correspond to the positions of the side baffles. When the lifting frame descends and drives the side limiting plates on its sides to lower, the side mounting blocks drive the side baffles to move downward, and when the position is too low, the side baffles can enter the side slots.

[0007] As a preferred technical solution of the present utility model, the mounting structure includes a front fixed shaft, a front spring, and a sleeving hole. Two front fixed shafts are fixedly arranged on the front side of the lathe base. The front fixed shafts extend upward from the front through slots. A front spring is fixed on the lathe base. The whole of the front spring is sleeved outside the front fixed shaft. The front protective plate is provided with a vertical sleeving hole and is movably sleeved on the front fixed shaft through the sleeving hole. Its lower surface is fixedly connected to the front spring. The upper part of the front protective plate contacts the bottom surface of the front limiting plate. Both the side baffle and the front protective plate are wooden plates, which are light in weight and good in material economy.

[0008] As a preferred technical solution of the present utility model, the locking structure includes a convex plate, a locking screw, and a screw hole. Convex plates are integrally formed on the rear sides of the left and right ends of the top of the front protective plate. The convex plates are fitted with locking screws. Screw holes are opened on the workbench, and their positions correspond to the positions of the locking screws. When the equipment is in a non-processing state, the front protective plate can be manually pressed down so that the convex plate contacts the workbench, and the locking screws are fitted with the screw holes to lock the position of the convex plate. At this time, the front protective plate will not affect the operation of the workpiece on the workpiece placement table.

[0009] The beneficial effects of the present utility model: Under the combined action of the side limiting plates on the side of the lifting frame and the side springs, the side mounting blocks are always at the height position below the lifting rack and drive the side protection to also be in this position. This position can accurately protect the vicinity of the cutting position of the tool. The front of the workbench is protected by the front through slot, the mounting structure, and the front protective plate. And when not cutting, the front protective plate is pressed down into the front through slot through the locking structure, so that it does not block the workpiece placement table and is convenient for operating the workpiece.
