Along with the development of society, the diversified degree of people to industrial products demand is more and more higher, this also impels equipment manufacturing technology to develop towards diversified form, and the traditional machine tool being representative with car, milling, plane, mill, pincers, brill cannot be competent at diversified part processing tasks.A large amount of special process equipment and corresponding special process method are just born under this overall background.
For the processing tasks of single peculiar part, general needs prepare a special process equipment specially to carry out, this equipment has the selectivity for above-mentioned peculiar part, namely this equipment does not generally possess the ability of processing other types part, therefore the kind of special process equipment is very various, but often kind of equipment generally only has one.The equipment of every employing cutting way processing parts, must have delivering gear, because the nonstandard parasexuality of special process equipment, and the mode that the tool feeding mechanism of these equipment is ununified.
The above situation result in some problems: all will redesign the delivering gear matched when often designing a kind of special process equipment, add the workload of designer, too increase equipment R&D costs; Must take into account that when designing the special process equipment space of cutter mechanism is arranged, the optimization of whole device space layout can be affected like this; These delivering gears are all that two ends extreme position controls, and do not possess the ability accurately controlling feed velocity and access site, the processing tasks required for there being degree of precision cannot complete, and occurs in process that the probability of waste product is also very high; These delivering gears do not possess self-lock ability, must continue to provide centripetal force in process, add the difficulty that feed controls.
Summary of the invention
In view of this, for the deficiencies in the prior art, technical problem to be solved by this invention is to provide a kind of accurate self-locking feed arrangement, the rotary motion utilizing worm-and-wheel gear, thread transmission, spline rotation preventive mechanism to be provided by motor converts the straight-line feed motion of cutter to after slowing down, realize the object of feed, compact conformation of the present invention, adopts modularized design, has feed self-lock ability and accurately controls the ability of feed velocity, access site.
To achieve these goals, structure is composed as follows in the present invention: worm screw (3) is arranged along Z axis, and two ends are fixed by a pair worm bearing (4), and described worm screw (3) is connected with worm gear (5).Described worm gear (5) is arranged along X, and two ends are fixed by a pair Worm Bearing (6), and there is a through hole in the axle center of described worm gear (5), and through-hole wall has screw thread.The interlude of screw rod (7) has screw flight (72), described screw rod (7) is through the through hole in worm gear (5) axle center, arrange along X-axis, the screw flight (72) of screw rod (7) and the screw thread of worm gear (5) carry out threaded engagement.There is screw rod tool rest (71) described screw rod (7) one end, and the other end has screw rod spline (73), and cutter (2) is arranged on screw rod tool rest (71).Above-mentioned all structure peripheral have casing (8) and cabinet cover (1), described casing (8) there is spline (81), described spline (81) is arranged along X-axis, and the screw rod spline (73) of screw rod (7) is installed in the spline (81) of casing (8).(1) has a through hole to described cabinet cover, and described through hole is arranged along X-axis, and it is outside that screw rod (7) has one end of screw rod tool rest (71) can reach cabinet cover (1) from described through hole.Casing (8) has through hole perpendicular on the face of Z axis, and it is outside to casing (8) that worm screw (3) has at least one end to pass described through hole.
Advantage of the present invention is as follows: present invention employs modularized design, have very strong versatility, can use on various process equipment, the present invention only need be arranged on the knife rest of process equipment by user, and the rotating shaft of motor is connected with worm screw of the present invention (3), the present invention can produce the series of products for having sizes specifications and models, selects for user.As shown in Figure 2, compact conformation of the present invention, profile rule, gearratio is large, and user only need reserve a very little block space on process equipment just can arrange the present invention, little on the space layout impact of whole equipment.Present invention utilizes the self-lock ability of worm-and-wheel gear, when process equipment stops feed, self-locking of the present invention, cutter (2) can remain on current location and not offset, and ensure that the quality of processing and the safety of process.Present invention utilizes worm-and-wheel gear, feature that thread transmission transmission accuracy is high, achieve the accurate control of feed velocity and access site, improve the precision of processing and the flexibility of process.

Detailed description of the invention
Exemplary embodiment is as follows: the present invention be arranged on the knife rest of process equipment, and one end that worm screw (3) stretches out casing (8) is connected with motor.Control the rotation direction of motor, just can control the present invention and perform feed action or tool backlash movement; Control the rotating speed of motor, just can control the feed speed of cutter (2); Control the angular displacement of motor, just can control the straight-line displacement amount of cutter (2).Motor stalls, self-locking of the present invention.
Operation principle labor of the present invention is as follows: motor by transmission of torque to worm screw (3), worm screw (3) by transmission of torque to worm gear (5), because screw rod spline (73) is subject to the rotation condition of spline (81) around X-axis, so screw rod (7) can not rotate around X-axis, worm gear (5) becomes screw rod (7) along the straight line force of X-axis around the torque conversion of X-axis with the threaded engagement of screw rod (7) by worm gear (5), screw rod (7) carry its tools (2) does rectilinear motion, realizes the object of feeding.Because worm and gear has the ability of self-locking, when cutter 2 and screw rod 7 are subject to the External Force Acting along X-axis, screw rod 7 can not be subjected to displacement.
The angular displacement of motor and the relation of cutter straight-line feed amount are as formula (1.1), the relation of motor speed and tool feeding speed is as formula (1.2): the angular displacement (unit: spend) of θ-motor, ω-motor speed (unit: rad/s), n
1-worm screw (3) head number, n
2-worm gear (5) number of teeth, the pitch (unit: mm) of P-screw flight (72), s-cutter straight-line feed amount (unit: mm), v-tool feeding speed (unit: mm/s).
The foregoing is only the preferred embodiments of the present invention, be not limited to the present invention, obviously, those skilled in the art can carry out various change and distortion to the present invention and not depart from the spirit and scope of the present invention.Like this, if these amendments of the present invention and distortion belong within the scope of claim of the present invention and equivalent technologies thereof, then the present invention also comprises these changes and distortion.
