In the utility model, above-mentioned carve characters milling head and the electric spark head of carving characters can be changed as required easily.

Its basic principle is: computer software is weaved in the exercises that machine is finished, finished by control and driving mechanism.Process with the head mechanism of carving characters at surface of the work, the movement locus of head mechanism in the space of carving characters is by three step motor control, i.e. X, Y, Z direction.X, Y direction control horizontal level, Z direction control upright position, font to be processed or symbol are after the keyboard input, program finds corresponding font in computer library, computer becomes the rotation of stepper motor to the output of the each point relative coordinate of font, reaches to control the movement position of head mechanism in the space of carving characters.

Characteristics of the present utility model are the work that original Artificial Control is finished, and become automatically and finish, and have alleviated labor intensity of operating personnel, improve working (machining) efficiency, need not make mould, and various fonts and size are fully by computer software control.

Describe the utility model in detail by following examples, but be not used in restriction the utility model.

Fig. 1 is the general structure schematic diagram of computer lettering machine.

Fig. 2 is a system block diagram.

Fig. 3 is the structural representation of milling head mechanism of carving characters.

Fig. 4 is the carve characters structural representation of head mechanism of electric spark.

With reference to Fig. 1,3, the milling head of carving characters of the present utility model ［ 1 ］ is stuck in the lower end of vertical axis ［ 2 ］, vertical axis ［ 2 ］ is fixed in the vertical conduit ［ 4 ］ by bearing ［ 3 ］, drive rotation by drive motors ［ 5 ］, vertical conduit ［ 4 ］ is by the motion of Z direction stepper motor ［ 6 ］ control Z direction, vertical conduit ［ 4 ］ cooperates with helicla flute on vertical conduit ［ 4 ］ wall by the pin ［ 8 ］ on the vertical conduit cover ［ 7 ］, when Z direction stepper motor ［ 6 ］ is worked, driving vertical conduit ［ 4 ］ rotates, spiral fluted relative motion by on pin ［ 8 ］ and vertical conduit ［ 4 ］ wall makes vertical conduit ［ 4 ］, vertical axis ［ 2 ］, coexist Z direction motion of the milling head ［ 1 ］ of carving characters.

Vertical conduit cover ［ 7 ］ is fixed on the base plate ［ 9 ］, be fixed with the directions X guide rail on the base plate ［ 9 ］ and pay ［ 10 ］ and directions X ball screw pair ［ 11 ］, the motion of directions X is to rotate the drive nut motion to drive base plate ［ 9 ］ motion by the screw rod that the stepper motor of directions X ［ 12 ］ drives the ball screw pair ［ 11 ］ of directions X, reaches the motion of control directions X.

The two ends that the guide rail of directions X is paid ［ 10 ］ and ball screw pair ［ 11 ］ are fixed on the support ［ 13 ］, are fixed with the Y traversing guide on the support ［ 13 ］ and pay ［ 14 ］ and Y direction ball screw pair ［ 15 ］, also are fixed with directions X stepper motor ［ 12 ］.The motion of Y direction is to rotate the drive nut motion to drive support ［ 13 ］ motion by the Luo Gang that the stepper motor of Y direction ［ 16 ］ drives the ball screw pair ［ 15 ］ of Y direction, reaches the motion of control Y direction.

The two ends that the guide rail of Y direction is paid ［ 14 ］ and ball screw pair ［ 15 ］ are fixed on the base, and base also is fixed with Y direction stepper motor ［ 16 ］.

With reference to Fig. 2, the principle of the present utility model and the course of work are described.

Input block ［ 101 ］ is input keyboard and the display that links to each other with microcomputer ［ 100 ］, font that input will be processed on keyboard and character, size, spacing.Microcomputer ［ 100 ］ sends instruction according to the signal of input to control and driver element ［ 102 ］, make stepper motor ［ 103 ］ motion of X, Y, Z direction, the motion of stepper motor drives driving mechanism ［ 104 ］ and the head mechanism of carving characters ［ 105 ］ motion, reaches to control the position of head in the space of carving characters.

Another road instruction that microcomputer ［ 100 ］ sends is to deliver to control and driver element ［ 106 ］, and control makes the drive motors ［ 107 ］ of the head rotation of carving characters.

When control and driver element ［ 102 ］ when breaking down, send signal to fault logic circuits ［ 107 ］, fault logic circuits ［ 107 ］ control exchanges solid switch ［ 108 ］ power-off protection, has cut off the circuit of dc source ［ 109 ］.
