The following is the model and function of each electrical device in this case:

Grinder: Model ESA-YS3040FN001, used for grinding workpieces.

Rotary cylinder: Model MSQB20A, used to drive the drill bit to rotate.

The first servo motor: the model is SGDM-02ADA, which is controlled by the servo driver of the model JASD4002-20Z, which is used to drive the first lead screw to rotate and replace the pulling of the first hand wheel.

The second servo motor: the model is SGDM-02ADA, which is controlled by the servo driver of the model JASD4002-20Z, which is used to drive the second lead screw to rotate, replacing the pulling of the second hand wheel.

The third servo motor: the model is SGDM-02ADA, which is controlled by the servo driver of the model JASD4002-20Z, which is used to drive the third lead screw to rotate, instead of the third hand wheel.

The following is the model and function of each component in this case:

Second lead screw: The second lead screw and the carriage are installed at an oblique angle. Compared with the horizontal lead screw on the market, this installation will make the second lead screw more rigid, which can also be guaranteed when the base is heavier. Stability of the drill.

Slider: There are vertical conical bumps on the slider to correspond with the scale on the scale.

Scale: Since the angle between the second lead screw and the carriage is fixed, the line spacing of the slider on the second lead screw can be calculated by the Pythagorean theorem according to the scale corresponding to the bump on the slider. Since the position of the drill bit is in one-to-one correspondence with the positions of the two sliders after sliding on the second lead screw, the position of the drill bit when the two sliders have different row spacings can be accurately positioned in this way, which makes drilling and grinding more efficient. Precise.

All the electrical components in this case are connected with the power supply to which they are adapted through wires by those skilled in the art, and an appropriate controller should be selected according to the actual situation to meet the control requirements. The specific connection and control sequence should refer to the following working principles Among them, the electrical connection between the electrical components is completed in sequence, and the detailed connection means are known in the art. The following mainly introduces the working principle and process, and does not describe the electrical control.

Example 1: Rotating the first hand wheel drives the first lead screw to rotate. During the rotation of the first lead screw, the carriage will move along the Z axis along the slideway between the carriage and the frame. Make the slider move up or down along the second lead screw, drive the base to move through the connecting rod, and perform Y-axis movement. The backing plate can make the grinder rotate to a proper angle, then unscrew the second bolt and insert it into the corresponding socket, and then push the grinding machine to make it follow the slideway between the second backing plate and the front or Move back, after reaching the proper position, unscrew the third bolt to press the pressure plate on the second pad, fix the grinder through the friction between the second pad and the pressure plate, and then start the grinder for grinding operation That is, when the grinding machine needs to be lifted, the third bevel gear on the connecting rod can be rotated by slowly rotating the third handwheel, and the fourth bevel gear can be driven to rotate, so that the third lead screw can be rotated. Rotation, with the rotation of the third lead screw, the bottom plate can not rotate, so it rotates relative to the third lead screw, so as to move up or down according to the rotation direction of the third lead screw, driving the grinder to raise or lower, Make the grinding wheel contact the drill bit to perform grinding. After the grinding is completed, rotate the third hand wheel in the opposite direction to lower the worktable and turn off the grinding wheel machine. Pull out the cover plate along the drill bit, then pull out the drill bit, insert the new drill bit into the insert plate, then cover the cover plate back so that the bumps are inserted into the grooves on the insert plate and the insert plate in turn, and then insert the first The bolt is screwed back to the first screw hole, which not only prevents the drill from falling off when the machine is working, but also prevents it from shaking left and right, and the disassembly process is more convenient.

Embodiment 2: After removing the first hand wheel in Embodiment 1, install the fifth bevel gear on the rear end surface of the first lead screw, install the first servo motor on the The sixth bevel gear is installed on the motor, so that the fifth bevel gear is meshed with the sixth bevel gear, and the first screw rod is rotated by the drive of the first servo motor, instead of the original method of pulling by the first hand wheel, The other structure remains unchanged, and it can also drive the effect of moving the carriage back and forth laterally. Although the cost is increased, it saves manpower, and the rotation angle of the servo motor to move the first screw rod is more accurate.

Embodiment 3: When the second hand wheel in Embodiment 1 is removed, then the roller is installed, and the second servo motor is installed on both sides of the frame, and the rotating end face of the servo motor is connected to the roller through the belt, and the second The servo motor rotates and drives the second bevel gear to rotate through the belt. The other structure remains unchanged, and the effect of driving the second lead screw to rotate can also be achieved. Although the cost is increased, it saves manpower, and the servo motor turns the first lead screw. The rotation angle is more precise.

Embodiment 4: When the third handwheel in Embodiment 1 is removed, then install the third servo motor on the inner and lower walls of the frame, so that the front end of the third bevel gear is directly connected with the third servo motor, Other structures remain unchanged, and the effect of driving the fourth bevel gear and the third lead screw to rotate can also be achieved. Although the cost is increased, manpower is saved, and the rotation angle of the first lead screw by the servo motor is more precise.

The above technical solutions only reflect the preferred technical solutions of the technical solutions of the present invention, and some changes that those skilled in the art may make to some parts of them all reflect the principles of the present invention and belong to the protection scope of the present invention. within.
