Description

Technical Field

[0001] The utility model belongs to the technical field of slotting machines, and particularly relates to a movable pressing plate device for a metal plate slotting machine. Background Art

[0002] A slotting machine is an important manufacturing machine, also known as a machine tool or machine tool, and is usually referred to as a machine tool. It plays an indispensable role in mechanical manufacturing. The main function of a slotting machine is to process metal sheets, especially to accurately cut the inner grooves and grooves of metal materials. Its working principle is to move the cutter wheel through the rotating milling cutter to achieve the purpose of cutting the metal workpiece and processing the inner groove or groove.

[0003] There is an obvious problem when slotting in the existing slotting machine, that is, its clamping device is fixed in one position and lacks flexibility. When the position where the slotting is required is blocked by the clamping device, the clamping device must be loosened first, and then the position of the metal plate must be adjusted manually. Such an operation process is not only time-consuming and labor-intensive, but also greatly reduces work efficiency. Utility Model Content

[0004] The utility model aims to provide a mobile pressing plate device for a metal plate slotting machine, which saves the manual adjustment of the metal plate position, is more convenient and labor-saving, improves the work efficiency, and also improves the stability and quality of slotting.

[0005] The technical solutions adopted in this utility are as follows:

[0006] A movable pressure plate device for a metal plate grooving machine comprises a machine tool, guide rails are provided at both ends of the top of the machine tool, a gantry is provided on the guide rails, a plurality of support ears are fixed on the top of the machine tool and on both sides of the guide rails, a rotating shaft is rotatably installed between the outer walls of the two support ears, a gear is provided on the outer wall of the rotating shaft, a connecting rod is fixed on the outer wall of the rotating shaft and on the gear, a clamping block for clamping a metal plate is fixed on the other end of the connecting rod, a third hydraulic cylinder is fixed on the top of the machine tool and on one side of the gear, a fixed plate is fixed on the output shaft of the third hydraulic cylinder, and a toothed plate meshing with the gear is fixed on the top of the fixed plate.

[0007] Furthermore, an electric slide rail is arranged inside the gantry, a first hydraulic cylinder is arranged at an output end of the electric slide rail, a mounting plate is fixed to an output shaft of the first hydraulic cylinder, and a cutter head is arranged at the bottom of the mounting plate.

[0008] Furthermore, mounting frames are provided on both sides of the top of the mounting plate, a second hydraulic cylinder is provided on the mounting frame, an annular plate is provided between the output shafts of the two second hydraulic cylinders, a plurality of rolling grooves are opened at the bottom of the annular plate, and balls are provided inside the rolling grooves.

[0009] The technical effects achieved by this utility model are:

[0010] The utility model discloses a movable pressing plate device for a metal plate slotting machine, wherein a clamping block is arranged, and a toothed plate on a fixed plate is driven to move up and down by a third hydraulic cylinder. The toothed plate cooperates with the gear and can drive the clamping block on the connecting rod to clamp the metal plate or rotate to the other side of the supporting ear to separate from the metal plate. The structure is simple, and when the clamping block hinders the slotting, it is only necessary to rotate the corresponding clamping block to the other side of the supporting ear, thereby eliminating the need for manual adjustment of the position of the metal plate, which is more convenient and labor-saving and improves work efficiency. The arranged annular plate and ball bearing can press the metal plate around the cutter head along the running path of the slotting machine, which not only presses the metal plate tighter, but also does not affect the slotting of the slotting machine, thereby improving the stability and quality of the slotting.

The plate 18 moves, the fixed plate 18 drives the toothed plate 19 to move, the toothed plate 19 meshes with the gear 16, the gear 16 drives the rotating shaft 13 to rotate, and the rotating shaft 13 drives the clamping block 15 on the connecting rod 14 to rotate, so that the metal can be stably clamped. When grooving the metal, there is a clamping block 15 that hinders the grooving, and the corresponding clamping block 15 can be rotated to the other side of the supporting ear 12 to separate the clamping block 15 from the metal plate, which is convenient for the smooth grooving. After the grooving is completed, the third hydraulic cylinder 17 is started to drive the clamping block 15 to clamp again; a guide rod slidably connected to the fixed plate 18 is fixed on the top of the machine tool 1, so that the up and down movement of the fixed plate 18 is relatively stable; the cross-section of the clamping block 15 is polygonal, which is convenient for the stable clamping of the metal plate. When clamping metal plates of different thicknesses, a flat surface on the clamping block 15 can be fitted with the metal plate to clamp the metal plate;

[0018] like Figure 1 and 3 As shown, the interior of the gantry 3 is provided with an electric slide rail 4, which is convenient for driving the cutter head 7 to move left and right, and the output end of the electric slide rail 4 is provided with a first hydraulic cylinder 5, which is convenient for driving the cutter head 7 to move up and down, and the output shaft of the first hydraulic cylinder 5 is fixed with a mounting plate 6, and the bottom of the mounting plate 6 is provided with a cutter head 7, which is relatively complete and the equipment is relatively complete, and it is convenient to groove the metal plate through the provided cutter head 7; mounting frames 8 are provided on both sides of the top of the mounting plate 6, and a second hydraulic cylinder 9 is provided on the mounting frame 8, and a second hydraulic cylinder 9 is provided between the output shafts of the two second hydraulic cylinders 9. There is an annular plate 10, and a plurality of rolling grooves are opened at the bottom of the annular plate 10. Balls 11 are arranged inside the rolling grooves. When grooving the metal plate, the second hydraulic cylinder 9 is started to drive the annular plate 10 to move downward, so that the annular plate 10 drives the balls 11 to squeeze the metal plate, and the metal plate around the cutter head 7 is pressed and held. It can move with the movement of the cutter head 7, thereby improving the stability and quality of the grooving. The setting of the annular plate 10 allows the mounting plate 6 to pass freely, which is more practical and prevents the mounting plate 6 from affecting the up and down movement of the annular plate 10, thereby facilitating the normal use of the equipment.

The toothed plate 19 drives the connecting rod 14 on the rotating shaft 13 to rotate through the gear 16. The connecting rod 14 drives the clamping block 15 to separate from the metal plate and rotate to the other side of the supporting ear 12, so that the slotting can be carried out smoothly. After the slotting is completed, the third hydraulic cylinder 17 is started again to make the clamping block 15 press the metal plate again.
