Background technology
At present,
?in large-scale moving-beam type numerical control plane milling and boring machine, moving beam often adopts counterweight balance structure, this structure by counterweight balance most of weight of moving beam and spindle processing unit, when alleviating the load of moving beam driving screw mandrel, moving beam can be participated in the processing interlock of product, can strengthen the processing stroke of product Z axis.Simultaneously, the method makes to have increased on portal frame the weight that is equivalent to one times of moving beam and spindle processing unit, this lightweight 20T, large-scale 30～the 40T that reaches, this has just increased larger burden to the driving of gantry frame, make the translational speed of gantry frame be difficult to improve, be unfavorable for the highly-efficient processing of product.
Summary of the invention
The object of the invention is to overcome above-mentioned weak point, a kind of moving beam clamping cylinder be provided,
By moving beam clamping cylinder, guaranteed the stable connection of moving beam, also ensured the smooth enforcement of the moving girder construction of hydro-cushion, be conducive to the realization of product function.This clamping cylinder adopts butterfly spring to clamp, and the version that hydraulic oil unclamps, adds man-hour at numerical control device, can fix moving beam position.
According to technical scheme provided by the invention, moving beam clamping cylinder comprises clamp, clamping bar, lever, support, axle, the dish of posting a letter, piston rod, cylinder body, butterfly spring and gland; Cylinder body is arranged on crossbeam by screw, and gland is connected with cylinder body by screw, and piston rod and butterfly spring are arranged in cylinder body and gland inner space, and make to form oil pocket between piston rod and cylinder body; Piston rod coordinates with piston rod installing hole in lever, and the top of piston rod is provided with the dish of posting a letter, for feeding back oil cylinder status information; Support is arranged on crossbeam by screw, and support is connected by axle with lever; Clamp is connected by screw on clamping bar.
As a further improvement on the present invention, one end of described piston rod and lever mated is furnished with taper faced washer, spheric washer, and the other end is furnished with spheric washer, and fixes by locking nut group.
As a further improvement on the present invention, described clamping bar profile is made as semi-cylindrical form, and is provided with semi arch draw-in groove at clamping bar middle part.
As a further improvement on the present invention, described clamping bar coordinates with semi-cylindrical with lever, and holding screw is fixed in the semi arch draw-in groove on clamping bar to fix to clamp bar.
Compared with the prior art the present invention has the following advantages:
The present invention is simple and reasonable for structure, by moving beam clamping cylinder, has guaranteed the stable connection of moving beam, has also ensured the smooth enforcement of the moving girder construction of hydro-cushion, is conducive to the realization of product function.Owing to increasing moving beam clamping cylinder, this clamping cylinder adopts butterfly spring to clamp, and the version that hydraulic oil unclamps, adds man-hour at numerical control device, can fix moving beam position; To guarantee that moving beam work in-process keeps stable.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
The specific embodiment
The present invention is below further described in connection with the embodiment in accompanying drawing:
As shown in Figure 1, the present invention is mainly comprised of clamp 1, clamping bar 2, holding screw 3, lever 4, support 5, axle 6, post a letter dish 7, locking nut group 8, taper faced washer 9, spheric washer 10, piston rod 11, cylinder body 12, butterfly spring 13, gland 14, taper faced washer 16 and spheric washer 17.Cylinder body 12 is directly installed on crossbeam 15 by screw, and gland 14 is connected with cylinder body 12 by screw, and cylinder body 12 is arranged piston rod 11 and butterfly spring 13 with gland 14 inner spaces, and makes to form oil pocket between piston rod 11 and cylinder body 12.Piston rod 11 coordinates with piston rod installing hole in lever 4, the two ends that coordinate with lever 4 at piston rod 11 are furnished with respectively taper faced washer 16, spheric washer 17 and taper faced washer 9, spheric washer 10, and fixing by locking nut group 8, the top of piston rod 11 is provided with the dish 7 of posting a letter, for feeding back oil cylinder status information.Support 5 is arranged on crossbeam 15 by screw, and support 5 is connected by axle 6 with lever 4, and can take axle 6 and as the center of circle, carry out low-angle revolution.Clamping bar 2 is designed to semi-cylindrical form, and at middle part, be designed with semi arch draw-in groove, clamping bar 2 coordinates with semi-cylindrical with lever 4, and the semi arch draw-in groove that holding screw 3 is fixed on clamping bar 2 is interior to fix to clamp bar 2, and tight piece 1 is connected by screw on clamping bar 2.
When between piston rod 11 and cylinder body 12, form oil pocket oil-feed time, piston rod 11 is to the direction motion of compression butterfly spring 13, and drive lever 4 to take axle 6 to move in the direction of the clock as the center of circle, contact between lever 4 and clamping bar 2 reduces, and clamp 1 also reduces with the pressure relief of column 18.Now, moving beam clamping cylinder is in releasing orientation, and moving beam can move.
When numerical control device need to complete processing tasks, the off-load of oil pocket pressure, piston rod 11 is done return motion under the effect of butterfly spring 13, and drive lever 4 take axle 6 as the center of circle by counterclockwise motion, contact between lever 4 and clamping bar 2 increases, and clamp 1 also increases with the pressure relief of column 18.Now, moving beam clamping cylinder is in clamped condition, and moving beam can not move.
In being connected of piston rod 11 in the present invention and lever 4, adopted the combination of two groups of taper faced washers and spheric washer, this structure can ensure that lever 4 is because carrying out clockwise or counterclockwise motion, and with 11 angulations whens conversion of piston rod, piston rod 11 can have certain floating space with being connected of lever 4.In the present invention, clamping bar 2 is also by semicircle cambered surface with being connected of lever 4, and this has just ensured no matter be to clamp or releasing orientation, clamping bar 2 can contact by semicircle cambered surface all the time with lever 4.
