Detailed Description
As shown in fig. 1 to 8, an angle grinder cutting frame comprises a frame 1, a guide device, a pressing device and a spring;
the rack 1 comprises a rectangular iron plate and a fixed hinge plate 2 vertically arranged at one end of the iron plate; a cutting through groove 10 is formed in the upper surface of the iron plate along the long side direction of the rectangle, and a fixing block is welded along the short side direction of the rectangle; the fixed hinged plate 2 is provided with two hinged holes on the top and one side surface respectively, and a connecting hole on the other side surface;
the guide device comprises four swing arms 3 and a moving hinged plate 3; the four swing arms are hinged in pairs in the horizontal and vertical directions through pin shafts, wherein a connecting hole is formed in the top of one swing arm 3 which is positioned above and close to the fixed hinged plate; the top of the movable hinged plate 4 is provided with two hinged holes, and one side surface of the movable hinged plate is provided with two hinged holes and a connecting hole;
the hinge holes of the movable hinge plates 4 are respectively hinged with the corresponding swing arms 3 through pin shafts; meanwhile, the hinge holes of the fixed hinge plates 2 are hinged with the corresponding swing arms 3 through hinge pins respectively;
the pressing device comprises a push-pull rod 6, a fixing bolt, an angle grinder 7 and a pressing swing arm 5; one end of the pressing swing arm 5 is provided with a V-shaped groove, two through holes are drilled on two surfaces of the V-shaped groove, the other end of the pressing swing arm is provided with two hinge holes, and the top surface of the pressing swing arm is provided with a connecting hole;
the fixed hinged plate 2 is connected with the connecting hole of the swinging arm 3 and the movable hinged plate 4 is connected with the connecting hole of the pressing swinging arm 5 through a second spring 9 and a first spring 8 respectively.
The iron plate is connected with the fixed hinge plate 2 in a welding mode. Support columns are welded at four corner ends of the lower end face of the iron plate.
The action process of the invention is as follows:
as shown in fig. 1 and 9, when cutting or grinding a workpiece, firstly, the angle grinder 7 is fixed on the pressing swing arm 5 through the push-pull rod 6 and the fixing bolt 12; secondly, clamping one end of a workpiece on a fixing block 11 of the frame 1, and aligning a cutting blade or a grinding blade on the angle grinder 7 to a position needing to be processed on the workpiece; then, a push-pull rod 6 of the screw-down device 6 is pressed downwards by hand to overcome the elastic force of a first spring 8, so that the first spring 8 is stressed and stretched to ensure that the cutting or grinding sheet is in contact with the workpiece for working, and the cutting depth of the angle grinder 7 is controlled by adjusting the downward rotating angle of the screw-down device; finally, the push-pull rod 6 is pulled outwards by hand to overcome the elastic force of the second spring 9, so that the second spring 9 is stressed and stretched, the swing arm 3 is driven to swing and extend, and meanwhile, the movable hinged plate 4 pushes the angle grinder 7 to move outwards. When the angle grinder 7 moves to the maximum stroke, the outward tension is removed, so that the second spring 9 is retracted inwards to return to the original position under the action of the elastic force, and the reciprocating circulating operation can ensure that the cutting blade or the grinding blade on the angle grinder 7 moves along a straight line. After cutting or grinding is finished, the push-pull rod 6 is loosened, so that the first spring 8 returns to the original position under the action of spring force, and the angle grinder 7 is guaranteed to be away from the surface of the workpiece.
In actual work, firstly, a proper type of the angle grinder is selected according to the size of the processed quantity, and the position of the angle grinder is fixed by using the push-pull rod 6 and the fixing bolt 12; secondly, the downward rotation angle of the pressing swing arm 5 should be adjusted according to the cutting depth of the workpiece to be processed, so as to achieve the desired processing accuracy.
The angle grinder adopts manual cutting or grinding, has simple structure, stable work and high safety factor, fixes the angle grinder 7 on the pressing swing arm 5 through the push-pull rod 6 and the fixing bolt 12, controls the up-and-down movement of the cutting blade by utilizing the elastic deformation of the pressing device and the spring I8, and controls the stroke of the angle grinder by utilizing the elastic deformation of the guide device and the spring II 9. The invention starts from energy conservation and consumption reduction of enterprises and improvement of working efficiency of workers, has obvious effect since 2019 implementation, can adjust stations of different workpieces within the working stroke range, has high cutting precision, high safety factor, small required installation space and low cost, avoids secondary grinding and finishing when the quality of a cut edge does not reach the standard, has the efficiency 2 times of that of the traditional processing method, and greatly improves the working efficiency.
