Abstract
The utility model relates to a rack and pinion transmission feed mechanism in the numerical control capstan head punch press field, and including a crossbeam, the middle part of crossbeam is provided with a supporting seat, rotationally is provided with a gear on the supporting seat, and the pivot of gear is connected through speed reducer and an output shaft transmission of the servomotor, and the length orientation of the edge crossbeam of crossbeam is equipped with a sharp guide rail, a coordinate on the sharp guide rail to be provided with a planker, the upper surface of planker be equipped with the same rack of sharp guide rail orientation, gear and rack mesh mutually. The during operation, the planker links to each other with the pay-off subassembly of lathe, can be used to the X axial pay-off of lathe, and can realize the high-speed high developments operation of crossbeam. The feed mechanism structure is simple, equitable, can bring into play the fast advantage of rack and pinion transmission speed, realizes high-speed pay-off; The device is used for numerical control capstan head punch press, can obviously improve the working efficiency of numerical control capstan head punch press.
Description
Technical field
The utility model relates to a kind of NC turret punch machine, particularly the feed mechanism on the NC turret punch machine.
Background technology
At present, what the feeding of NC turret punch machine was adopted is the ball-screw transmission mechanism, because ball-screw is slender axles, poor rigidity is vibrated greatly in the running, and the high more vibration of speed is big more, cause driving error big, influence the NC turret punch machine operating accuracy, thereby restricted NC turret punch machine to high speed, the high dynamically development of direction, the current client of incompatibility is to the high efficiency demand trend of NC turret punch machine.、
The utility model content
The purpose of this utility model provides a kind of rack-and-pinion transmission feed mechanism, and the vibration when making its feeding is little, and response speed is fast, to improve the feeding speed of NC turret punch machine.
The purpose of this utility model is achieved in that a kind of rack-and-pinion transmission feed mechanism, comprise crossbeam, the middle part of described crossbeam is provided with supporting seat, be provided with gear on the supporting seat rotationally, the rotating shaft of described gear is in transmission connection through the output shaft of reductor and servomotor, the edge of described crossbeam is provided with line slideway along the length direction of crossbeam, be equipped with planker on the described line slideway, the upper surface of planker is provided with the tooth bar identical with the line slideway direction, and described gear and tooth bar are meshed.
During the utility model work, planker links to each other with the feeding material component of lathe, can be used for the X axis feeding of lathe, tooth bar is directly installed on the planker, gear and tooth bar only produce active force at the position that is meshed, its good rigidly, guaranteed gear and tooth bar at a high speed, accurately, transferring power reposefully.Simultaneously, the power that produces during the rack-and-pinion engagement, only crossbeam is installed the position generation active force of transmission device, other parts do not have the external force effect, like this, strengthen as long as crossbeam is installed the partially rigid of transmission device, the weight reduction of can trying one's best of other parts, thus can realize the high dynamic operation of crossbeam high speed.This feed mechanism is simple and reasonable for structure, can bring into play the fast advantage of rack-and-pinion transmission speed, realizes the high speed feeding; This device can be applicable on the NC turret punch machine, can obviously improve the operating efficiency of NC turret punch machine.
Description of drawings
Fig. 1 is the utility model structural representation.
Wherein, 1 tooth bar, 2 gears, 3 plankers, 4 line slideways, 5 crossbeams, 6 supporting seats, 7 reductors, 8 servomotors.
The specific embodiment
As shown in Figure 1, be a kind of rack-and-pinion transmission feed mechanism, its structure mainly includes crossbeam 5, the middle part of crossbeam 5 is provided with supporting seat 6, fixedly connected through screw between supporting seat 6 and the crossbeam 5, be provided with gear 2 on the supporting seat 5 rotationally, the rotating shaft of gear 2 is in transmission connection through the output shaft of reductor 7 with servomotor 8, the edge of crossbeam 5 is provided with line slideway 4 along the length direction of crossbeam, be equipped with planker 2 on the line slideway 4, the upper surface of planker 2 is provided with the tooth bar 1 identical with line slideway 4 directions, and gear 2 and tooth bar 1 are meshed.
This rack-and-pinion transmission feed mechanism is used on NC turret punch machine, its feeding speed has reached 100m/min, and the VT-300 type NC turret punch machine of employing ball-screw transmission feed mechanism, its feeding speed only has 60m/min, and this device has improved 1.67 times than the feeding speed of prior art.And, can realize big acceleration owing to light weight, good rigidly, be particularly suitable for the frequent requirement of NC turret punch machine feed mechanism start-stop.Through test, prove that NC turret punch machine adopts rack-and-pinion transmission feed mechanism, can realize that the high speed of feeding is dynamically high, can satisfy the client day by day to the high efficiency requirement of NC turret punch machine.
