Background technique

Before the invention of the utility model, there were two control modes of mechanical and hydraulic pressure for the lifting of the workbench of the slotting machine. The mechanical control method is limited by the structure, and its rising distance per step can only be fixed at several levels; the hydraulic control method can theoretically realize stepless adjustment of the rising distance per step, but due to the influence of hydraulic components, its control accuracy is very low; and the two In this control mode, the rising distance and falling speed of each step are fixed during the processing. Due to the above reasons, the selection of the best processing parameters is limited, which affects the processing accuracy, efficiency and tool life. the

Contents of the invention

The purpose of this utility model is just to overcome above-mentioned defect, design adjustable wrench groove numerical control slotting machine. the

The technical scheme of the utility model is:

CNC slotting machine with adjustable wrench groove, the bed is installed on the base, its main technical feature is that the ram is connected with the inclined guide rail on the bed, and reciprocates along the guide rail; the workbench is connected with the vertical guide rail on the bed, and moves vertically along the guide rail , the lifting system is installed under the workbench; in the lifting system, the bearing seat is installed at the bottom of the workbench, the lifting screw is connected with the bearing seat for relative rotation only, the screw nut is connected with the nut seat, and the nut seat is installed on the base , the servo motor is installed inside the workbench, the servo motor synchronous pulley is connected with the servo motor, and the screw synchronous pulley is connected with the lifting screw. the

The utility model has the advantage of controlling the rotation direction, rotation angle and rotation speed of the lifting screw rod through the numerical control system to set the workbench lifting, lifting distance, and lifting speed, with high control precision and convenient debugging; Unequal workpieces can be set to unequal rising distances to change the processing volume, achieve uniform load on the machine tool and tool, and improve the life of the machine tool and tool; when setting the falling speed, it will not be restrained by the rising speed, and the maximum falling speed can be obtained, saving Machining changeover time improves work efficiency. the

Other advantages and effects of the present utility model will continue to be described below. the

Each label in the figure indicates the name of the corresponding part as follows:

Bed 1, inclined guide rail 1-1, vertical guide rail 1-2, base 2, ram 3, worktable 4, screw bearing seat 5, lifting screw 6, screw nut 7, nut seat 8, servo motor synchronization Pulley 9, screw mandrel synchronous pulley 10, servo motor 11, slotting knife 12, workpiece 13, fixture 14, cross slide 15, adjustment mechanism 15-1. the

Detailed ways

As shown in Figure 1 and Figure 2:

The bed 1 is installed on the base 2, the ram 3 is connected with the inclined guide rail 1-1 on the bed 1 and reciprocates along the guide rail, and the working table 4 is connected with the vertical guide rail 1-2 on the bed 1 and moves along the vertical guide rail The cross slide 15 is connected with the workbench 4, the adjustment mechanism 15-1 is connected with the cross slide 15, the fixture 14 is installed on the cross slide 15; angle; the vertical guide rail 1-2 is located at the lower part of the bed 1 and forms an angle of 90 degrees with the workbench 4. the

The lifting system consists of a screw bearing seat 5, a lifting screw 6, a screw nut 7, a nut seat 8, a motor synchronous pulley 9, a screw synchronous pulley 10, and a servo motor 11; the bearing seat 5 is installed at the bottom of the workbench 4 , the lifting screw 6 is connected with the bearing seat 5, and only performs relative rotation movement, the screw nut 7 is connected with the nut seat 8, and the nut seat 8 is installed on the base 2; the servo motor 11 is installed on the inner boss of the workbench 4 On, be connected with workbench 4 and rise with it; Servo motor synchronous pulley 9 is connected with servo motor 11, screw mandrel synchronous pulley 10 is connected with lifting screw mandrel 6. the

Because the groove 13-1 on the workpiece 13 is to be machined, its width is only 6mm or less, and the inserting tool 12 cannot enter the groove 13-1 as a whole; Angle, to form transverse slotting, so that the part of slotting knife 12 enters in the groove 13-1 and can complete slotting. the

Description of the utility model application process:

Clamp the workpiece 13 on the fixture 14, align the workpiece 13 with the inserting knife 12 through the adjustment mechanism 15-1 on the cross slide 15, and set the total stroke and step distance of the workbench 4 through numerical control programming;

Start the machine tool, the workpiece 13 gradually rises until the groove 13-1 on the workpiece 13 is inserted, and the workbench 4 descends rapidly and returns to the starting position. the

During work, when the ram 3 makes a reciprocating motion, that is, after a slotting, the servo motor 11 is controlled to rotate an angle, which drives the servo motor synchronous pulley 9 and the screw synchronous pulley 10 to rotate at the same angle, and the screw synchronous pulley 10 Drive the lifting screw 6 to rotate at the same angle. Since the screw nut 7 is fixed, the lifting screw 6 rises and drives the worktable 4 to rise a certain distance through the bearing seat 5 to complete a longitudinal feed. By controlling the servo motor 11, each rotation angle Different longitudinal feeds can be obtained, the above process is repeated, and as the worktable 4 rises gradually, the groove 13-1 on the workpiece 13 is inserted from top to bottom, and the processing is completed. The servo motor 11 is controlled to rotate in reverse at a high speed, and the workbench 4 is rapidly lowered to the initial position to complete a processing process. the

Compared with the prior art, the utility model can double the production efficiency and shorten the adjustment time. the

The scope of protection claimed by the utility model is not limited to the description of this embodiment. the
