Abstract
The utility model discloses an upward-downward movement mechanism for a head of a linear cutting machine. The upward-downward movement mechanism comprises a rack on which an upright post is fixedly arranged. The head is in sliding connection with the upright post. A motor is fixedly arranged on the back of the upright post. A gear is fixedly arranged on an output shaft of the motor. A rack is in sliding connection in the upright post, and is matched with the gear. The head is connected with the rack. When the upward-downward movement mechanism is used, the gear is driven by the motor to rotate to drive the rack to move up and down, and the rack and the head are fixed together, so that the head can move up and down together with the rack when the rack moves up and down. Compared with the conventional lead screw drive, gear and rack drive is higher in efficiency; and by the gear and rack drive, the upward-downward movement speed of the head is greatly increased.
Description
Technical field
The utility model relates to the wire cutting machine tool technical field, especially relates to a kind of up and down mechanism of head of wire cutting machine tool.
Background technology
The head of wire cutting machine tool all can move up and down, and is all by leading screw transmission campaign.Concrete.Referring to Fig. 1, a kind of schematic diagram of head up and down mechanism of traditional wire cutting machine tool is disclosed in Fig. 1, comprise column 2 and head 3, be provided with leading screw 9 in column 2, be provided with internal thread 31 in head 3, described internal thread 31 matches with described leading screw 9, and an end of leading screw 9 is connected with motor (not looking out in figure).During use, the driven by motor leading screw rotates, and when leading screw rotates, moves up and down by thread belt motivation head.
The shortcoming of this structure is, the inefficiency of lead screw transmission, and leading screw rotates a circle, and head could be up or toward the distance of next pitch, but this speed that just makes head move up and down is very slow, can't reach quick response.
Summary of the invention
The utility model provides a kind of up and down mechanism of head of wire cutting machine tool for deficiency of the prior art, and transmission efficiency improves greatly, and the speed that head slides up and down improves greatly.
For solving the problems of the technologies described above, the utility model is solved by following technical proposals: the head of wire cutting machine tool up and down mechanism, comprise frame, be fixed with column on described frame, slidably connect head on described column, described column back is fixed with motor, be fixed with gear on the output shaft of described motor, slidably connect tooth bar in described column, described gear is meshed with described tooth bar, and described head is connected with described tooth bar.During use, motor driven gear rotates, and gear rotates the band carry-over bar and moves up and down, and tooth bar and head are fixed together, and therefore, when tooth bar moved up and down, head is and then motion together also, and this has just realized moving up and down of head.Traditional lead screw transmission of comparing, the efficient of rack-and-pinion transmission is higher, and utilizes the rack-and-pinion transmission, and the speed that head moves up and down is also accelerated greatly.
In technique scheme, preferred, be provided with chute longitudinally in described column, described tooth bar is slidably connected in described chute.Chute has limited the direction of motion of tooth bar can only be along the longitudinal, offset direction when preventing that head from sliding.
In technique scheme, preferred, described motor is reducing motor.Can certainly adopt the form of common electric machine acceleration and deceleration case, also can reach same effect, but can increase cost.
The beneficial effects of the utility model are: during use, motor driven gear rotates, and gear rotates the band carry-over bar and moves up and down, and tooth bar and head are fixed together, and therefore, when tooth bar moved up and down, head is and then motion together also, and this has just realized moving up and down of head.Traditional lead screw transmission of comparing, the efficient of rack-and-pinion transmission is higher, and the rack-and-pinion transmission, and the speed that head moves up and down is also accelerated greatly.
Description of drawings
Fig. 1 is the schematic diagram of the head up and down mechanism of existing wire cutting machine tool.
Fig. 2 is the schematic diagram of the utility model embodiment.
The specific embodiment
Below in conjunction with accompanying drawing and the specific embodiment, the utility model is described in further detail: referring to Fig. 2, the up and down mechanism of the head of wire cutting machine tool, comprise frame 1, be fixed with column 2 on described frame 1, slidably connect head 3 on described column 2, described column 2 backs are fixed with motor 4, in the present embodiment, preferred motor 4 adopts reducing motor, can certainly adopt the form of common electric machine acceleration and deceleration case, also same effect can be reached, but cost can be increased.Be fixed with gear 41 on the output shaft of described motor 4, be provided with chute 22 in described column 2, slidably connect tooth bar 21 in described chute 22.Described gear 41 is meshed with described tooth bar 21, and described head 3 fixes with described tooth bar 21.
During use, motor 4 driven gears 41 rotate, and gear 41 rotates band carry-over bar 21 and moves up and down, and tooth bar 21 is fixed together with head 3, and therefore, when tooth bar 21 moved up and down, head 3 is and then motion together also, and this has just realized moving up and down of head.Traditional lead screw transmission of comparing, the efficient of rack-and-pinion transmission is higher, and the rack-and-pinion transmission, and the speed that head moves up and down is also accelerated greatly.
