A tool support (13) capable of moving in the length direction of the swing arm (4) driven by a synchronous belt (11) is arranged on the swing arm (4), a cutting head (10) is arranged on the tool support (13), and the synchronous belt (11) is driven by a synchronous pulley of a radial stepping motor (16) installed on the swing arm (4). The cutter of the polar coordinate can ensure high arc cutting accuracy under the condition of low device accuracy requirements and enables machinery cost of a device and cost of a numerical control device to be greatly reduced.

Description

The polar coordinates cutting machine

Technical field

The utility model relates to the cutting machine of a kind of glass-cutting and sheet material aspect.

Background technology

So-called Numerical control cutting just is meant the workpiece instruction (or program) that is used to control lathe or equipment, is with the given a kind of new control mode of digital form.When this instruction was offered the control device of numerical control automatic gas cutting machine, cutting machine just can automatically cut according to given program.Numerical control cutting is made up of digital control system and mechanical framework two large divisions.Compare with semi-automatic cutting with conventional manual, Numerical control cutting is cutting technique, cutting technique and the automatic control technology that controller provides through digital control system, effectively controls and improves cut quality and cutting efficiency.

General Numerical control cutting equipment adopts the rectangular co-ordinate form mostly at present; When carrying out circular arc and curvilinear cut, need accomplish through interpolation operation; When cutting process is higher to required precision, just very high for servo required precision with drive system, can cause the cost of equipment to strengthen.

The utility model content

The utility model technical problem to be solved provides a kind of cutting that is mainly used in glass and sheet material, the polar coordinates cutting machine that cutting path mainly is made up of straight line and circular arc.

In order to solve above-mentioned technical problem; The technical scheme of the utility model is: a kind of polar coordinates cutting machine, and it comprises base, directly over base, is provided with middle cross beam; The centre position of middle cross beam is equipped with the revolution drive stepping motor, and said revolution drive stepping motor drives swing arm and rotates; Be equipped with in the said swing arm through synchronous band and drive the tool holder that can move along the pendulum arm length direction, on the said tool holder cutting head is installed, said synchronous band drives through the synchronous pulley of the radial stepping motor installed in the swing arm.

End in said swing arm is provided with ball bearing, and said ball bearing moves along circular orbit.

Said swing arm is provided with guide rod, and said tool holder moves along guide rod.

The utility model adopts the numerical control cutting machine of polar coordinate mode under the lower situation of equipment precision requirement, can guarantee higher circular arc cutting accuracy, and the machine cost of equipment and the cost of numerical control device are reduced greatly.

Description of drawings

Below in conjunction with the accompanying drawing and the specific embodiment the utility model is done further detailed explanation.

Fig. 1 is the structural representation of the utility model.

Fig. 2 is the Facad structure figure of swing arm part.

Fig. 3 is the reverse side structure chart of swing arm part.

The specific embodiment

As shown in Figure 1; Two bracing frames 2,3 about installing on the base 1; Bracing frame 2,3 tops are installed three crossbeams and are formed frame structure, and what slew gear wherein was installed is middle cross beam 5, and revolution drive stepping motor 6 is installed on the centre position of middle cross beam 5; And through the swing arm assembly below these revolution drive stepping motor 6 drives, the major part of swing arm assembly is swing arm 4.A ball bearing 9 is equipped with in the outer end of swing arm assembly, and this ball bearing 9 moves on a circular orbit 7, and the swing arm assembly is played a supporting role.

Middle cross beam 5 parts are concrete to be realized like this: the downside at middle cross beam 5 centers is installed an axle sleeve 15, and the top is equipped with revolution drive stepping motor 6, and revolution drive stepping motor 6 through the propeller shaft couplings in shaft coupling and the axle sleeve 15 together.A connection support 14 is equipped with in the power transmission shaft lower end, and this connection support 14 links together through the swing arm 4 of screw and polar coordinates cutting machine again.When being rotated under the instruction of revolution drive stepping motor 6 at controller, can drive the gyration that circumferencial direction is done in swing arm 4, this motion both can be clockwise, also can be counterclockwise.

About two bracing frame 2,3 middle parts, and the outside of both sides crossbeam all has 8 pairs of circular orbits of a connecting rod to play a supporting role, and guarantees the locus of circular orbit.

Like Fig. 2, shown in 3; Radial stepping motor 16 is housed on the swing arm assembly; Synchronous pulley is housed on 16 of this radial stepping motors drives synchronously and carry out the motion of horizontal direction, because the rear portion of tool holder 13 links together with band synchronously, when being with 11 motions synchronously with 11; Can drive tool holder 13 and do straight reciprocating motion together, cutting head 10 is installed on the tool holder 13 is used for plate is cut.Its guide effect of motion of 12 pairs of tool holders of a circular guide rod is installed in swing arm 4.

Concrete implementation is: the radial motion of polar coordinates cutting machine is to accomplish through the radial drive stepper motor 16 that is installed on the swing arm assembly; The axle of this motor drives through a synchronous pulley is with 11 to move synchronously; Synchronously with a side of 11 and tool holder 13 be linked together; So when being with 11 motions synchronously; Can drive tool holder 13 and do the reciprocating motion on the horizontal direction together, the guiding of tool holder 13 is to realize that through the circular guide rod 12 and the linear bearing of tool holder 13 belows that are installed in the swing arm 4 linear bearing is equipped with in tool holder 13 bottoms; This linear bearing is enclosed within on the circular guide rod 12 and slides, thereby has guaranteed the straight line precision in the tool holder 13 reciprocating motion processes.Incisory special-purpose cutting head 10 can be installed on tool holder 13, both can be the cutting head of contact, also can be the noncontact cutting head of laser type.Through swing arm 4 at the gyration of circumferencial direction and tool holder 13 in the formed Union Movement of rectilinear motion radially, just can carry out cutting work to the cutting path of arbitrary graphic.

The foregoing description limits the utility model never in any form, and every employing is equal to the technical scheme that replacement or the mode of equivalent transformation obtain and all drops in the protection domain of the utility model.
