Technical field
The utility model relates to machine tool feed drive technology field, is specifically related to plate milling unit axis feeding rack and pinion drive mechanism.
Background technology
The steel plate that the enclosed plate milling unit is used for that needs are welded carries out groove processing, is applicable to all kinds of Steel structure manufacturing enterprises and ERW manufacturing enterprise.This machine can be processed two edges of boards simultaneously, and can carry out reciprocal milling, existing climb cutting when milling, upmilling is also arranged, its cutting feeding realizes that by the rack-and-pinion transmission elimination of rack-and-pinion back lash is to guarantee that stable cutting is continuous, prolongs the blade key element in service life.At present, the elimination rack-and-pinion inter space device that adopts mainly contains machinery, hydraulic pressure, electric three kinds of methods both at home and abroad, the wherein electric crack that disappears is to adopt the electrical compensation principle crack that disappears, and very high to the reliability requirement of electrical system, design of electrical system is also comparatively complicated; The crack method that fixedly disappears is usually adopted in machinery, the hydraulic pressure crack that disappears, and is higher to the tooth bar requirement on machining accuracy, requires employing grinding size, and cost is very high.
Summary of the invention
The purpose of this utility model will be eliminated above-mentioned the deficiencies in the prior art and shortcoming exactly, provides a kind of hydraulic floating simple, low-cost, that effectively improve working (machining) efficiency to eliminate the rack-and-pinion inter space device.
In order to achieve the above object, the utility model provides a kind of hydraulic floating to eliminate the rack-and-pinion inter space device, described device comprises two-way hydraulic cylinder, floating axle, floating axle helical gear A, floating axle helical gear B, driving shaft, the driving shaft helical gear, driven shaft and driven shaft helical gear, floating axle is fixedlyed connected with two-way hydraulic cylinder, fixed installation floating axle helical gear A and floating axle helical gear B on the floating axle, and floating axle helical gear A is opposite with floating axle helical gear B tooth preface, driving shaft is fixedlyed connected with the driving shaft helical gear, driving shaft helical gear and floating axle helical gear A are connected with a joggle, driven shaft is fixedlyed connected with the driven shaft helical gear, and driven shaft helical gear and floating axle helical gear B are connected with a joggle.
The beneficial effects of the utility model:
Hydraulic floating provided by the utility model is eliminated the rack-and-pinion inter space device and is added man-hour actual, as long as adjust cylinder pressure, just can realize the tight engagement of the active spur gear and the tooth bar flank of tooth easily, and not be subjected to the influence of tooth bar machining accuracy.Only need corresponding change hydraulic cylinder oil-feed direction get final product when feed reverse, control element is simple, reliable, can realize automation control, and cutting is continuously even, the working (machining) efficiency height, and blade life is long, has effectively improved production efficiency.
Description of drawings
Fig. 1 is a kind of structural representation of the present utility model.
The specific embodiment
Embodiment:
A kind of as shown in Figure 1 hydraulic floating is eliminated the rack-and-pinion inter space device, comprise two-way hydraulic cylinder 3, floating axle 7, floating axle helical gear A5, floating axle helical gear B6, driving shaft 1, driving shaft helical gear 4, driven shaft 2 and driven shaft helical gear 8, floating axle 7 is fixedlyed connected with two-way hydraulic cylinder 3, fixed installation floating axle helical gear A5 and floating axle helical gear B6 on the floating axle 7, and floating axle helical gear A5 is opposite with floating axle helical gear B6 tooth preface, driving shaft 1 is fixedlyed connected with driving shaft helical gear 4, driving shaft helical gear 4 and floating axle helical gear A5 are connected with a joggle, driven shaft 2 is fixedlyed connected with driven shaft helical gear 8, and driven shaft helical gear 8 and floating axle helical gear B6 are connected with a joggle.
When driving shaft 1 need be rotated counterclockwise, two-way hydraulic cylinder 3 top oil-feeds, promoting floating axle 7 moves downward, floating axle helical gear A5 also moves down, promoting driving shaft helical gear 4 is rotated counterclockwise, make driving shaft 1 rotating certain angle in advance counterclockwise, driving shaft operation gear 9 and tooth bar are fitted tightly, eliminated the gap of rack-and-pinion.Simultaneously because floating axle helical gear B6 gear helical angle direction is opposite with floating axle helical gear A5, drive driven shaft helical gear 8 and clockwise rotate certain angle, eliminated the gap of driven shaft operation gear 10 with tooth bar, prevent the broaching tool that the climb cutting power in working angles takes place greater than upmilling power, creeping phenomenon occurs.
When driving shaft 1 need turn clockwise, two-way hydraulic cylinder 3 bottom oil-feeds, promoting floating axle 7 moves upward, floating axle helical gear A5 also moves up, promoting driving shaft helical gear 4 turns clockwise, make driving shaft 1 rotating certain angle in advance clockwise, driving shaft operation gear 9 and tooth bar are fitted tightly, eliminated the gap of rack-and-pinion.Simultaneously because floating axle helical gear B6 gear helical angle direction is opposite with floating axle helical gear A5, drive driven shaft helical gear 8 and rotate counterclockwise certain angle, eliminated the gap of driven shaft operation gear 10 with tooth bar, prevent the broaching tool that the climb cutting power in working angles takes place greater than upmilling power, creeping phenomenon occurs.
Provided by the utility modelly add man-hour, as long as adjust cylinder pressure, just can realize the initiatively tight engagement of spur gear and the tooth bar flank of tooth easily, and not be subjected to the influence of tooth bar machining accuracy actual.Only need corresponding change hydraulic cylinder oil-feed direction get final product when feed reverse, control element is simple, reliable, can realize automation control, and cutting is continuously even, the working (machining) efficiency height, and blade life is long, has effectively improved production efficiency.
Above-described only is preferred embodiment of the present utility model; should be understood that for the person of ordinary skill of the art; under technology enlightenment provided by the utility model; common practise as this area; other equivalent modifications and improvement can also be made, also protection domain of the present utility model should be considered as.
