Description
Technical Field
The utility model belongs to the field of machine tool fixtures, and particularly relates to a fixture for a linear cutting machine. The special-shaped piece is used for processing the plate, the special-shaped piece, the deformation piece and the like which form a certain angle with the bottom plane.
Technical Field
The numerical control linear cutting machine adopts a numerical control system, can automatically finish the machining process, can not carry out secondary finish machining when the precision requirement of the machining surface is not high, has small material consumption, can machine workpieces with complex shapes which are difficult to machine or cannot be machined by the traditional cutting machining method, is very suitable for machining small batches of parts with complex shapes, single pieces and test products, has short machining period, and is inconvenient in the machining process of workpieces which are long (longer in the cutting range of the machine tool) and need angle cutting, workpieces without installation references parallel to the machining surface, workpieces which are irregular in shape and the like, and can prevent the workpieces from deforming after machining, thereby being unfavorable for the application of the linear cutting machine.
The workpiece to be machined of the machine tool is placed on two parallel tracks perpendicular to the cutting wires and fixed by the pressing plate, namely the workpiece to be machined needs to have a basic plane perpendicular to the machining surface for placing the workpiece. But is difficult to process in the following cases:
1. if the surface to be processed forms a certain angle with the bottom plane, an additional cushion block is needed to form a required angle, the angle is not easy to adjust and fix, once the angle is not fixed, the cutting wire is broken off due to movement in the processing process, and the precision of the processing surface of the workpiece is reduced and the waste of materials and cutting wires is caused.
2. When the irregular workpiece is processed, two tracks are needed to fix the workpiece, and when the position to be cut is at one end edge or cut is started from one end, the tracks for fixing the workpiece influence the processing or are easy to damage, or one track loses support due to the processing of the workpiece to cause the workpiece to move, so that the cutting wire is broken and the processing cannot be continued.
3. The numerical control wire cutting machine tool is used for machining a workpiece, belongs to electric spark machining, generates certain heat, generates serious heat along with the inflow of cooling liquid, and can deform a workpiece when a thin plate or the workpiece with certain internal stress is machined. When a workpiece is machined, the narrow side of a 12 inch (or 10 inch) flat file needs to be machined to form an angle of 60 degrees with a large plane, the file after machining by a numerical control linear cutting machine tool generates bending of about 5 degrees along the longitudinal section and the surface with small removal amount of the cross section.
Therefore, a clamp which meets the above processing requirements, is safe and firm, is convenient to adjust, is simple to operate and is reliable in clamping is urgently needed.
Disclosure of Invention
The utility model aims to provide a clamp for a linear cutting machine, which is simple to operate and reliable in clamping.
The technical scheme adopted is as follows:
a clamp for a linear cutting machine comprises a base, an indexable clamping plate, an upper clamping plate, clamping screws, upper adjusting screws and lower adjusting screws.
The technical key points are as follows:
the base is hinged by a rotatable clamping plate with a rotating shaft.
The indexable clamping plate is fixed with the upper clamping plate by a plurality of clamping screws, the indexable clamping plate is provided with a plurality of lower adjusting screws extending upwards, the upper clamping plate is provided with a plurality of upper adjusting screws extending downwards, and the upper adjusting screws are opposite to the lower adjusting screws in upper and lower positions.
A support is provided below the indexable clamping plate.
The support may include an upper support link and a lower support link.
The upper end of the upper support connecting rod is hinged with the lower part of the indexable clamping plate through an upper support connecting rod shaft.
The lower end of the lower support connecting rod is hinged with the upper part of the base through a support connecting rod shaft.
The lower end of the upper support connecting rod is connected with the upper end of the lower support connecting rod through a positioning fastening screw and can rotate and fasten and position.
The advantages are that:
the utility model has the advantages of reliable clamping, simple operation, convenient adjustment, safety, firmness and higher efficiency, and can expand the application range of the linear cutting machine tool so as to meet the special processing requirements of workpieces.
The plate-shaped workpiece with the plane to be processed and the bottom plane forming any angle between 0 degrees and 90 degrees can be processed, the plate-shaped workpiece is fastened and positioned by the positioning fastening screw for fastening the supporting connecting rod, and the plate-shaped workpiece is simple to adjust, convenient to use, accurate in angle and reliable in positioning. The special-shaped workpiece can be positioned in multiple points by adjusting corresponding adjusting screws, so that the workpiece is positioned more firmly and reliably.
The clamping of the workpiece can be finished by only one track of the machine tool for processing the workpiece with a certain weight (the size of the random bed and the strength of the track are determined), so that the time for moving and fixing the other track is reduced, and the situation that the track is cut by misoperation is prevented when the single-sided workpiece is processed.
The workpiece which can generate deformation after processing is reversely pre-bent by adjusting the upper adjusting screw and the lower adjusting screw before processing, so that the deformation generated after processing can be counteracted. When the narrow side of the 12-inch flat file is processed and forms an angle of 60 degrees with the plane of the file, the file is adjusted by a corresponding adjusting screw when the clamp is fixed, and the file is bent to form an angle of about 5 degrees towards the side with more removal amount, so that the file forms a circular arc shape, and after the processing is finished, the pre-bending amount can be counteracted due to the redistribution of stress, so that the processed file can meet the use requirement.
The installation is convenient, firm and reliable. The base of the clamp can drill a plurality of hole sites according to the actual condition of the linear cutting machine tool rail, is used for connecting and positioning with the rail, can be fixed by only two common bolts, is in surface-to-surface contact, is firm and reliable in positioning, and is convenient and rapid.
The application range of the numerical control linear cutting machine tool is widened, and the special processing requirement of the workpiece is met.
The clamping is reliable, the operation is simple, the adjustment is convenient, and the positioning requirement of workpiece processing can be ensured only by correspondingly fastening and adjusting the corresponding fastening screw and the corresponding adjusting screw.
