Abstract
A floating supporting and pressing device comprises a pressing plate support, a pressing plate, a floating support and a squeezing support. The pressing plate support is provided with vertical and axial slides, and the floating support, the squeezing support and a spring are disposed inside the slides. The pressing plate is fixed on the pressing plate support through a screw bolt. Each of the floating support and the squeezing support inside the pressing plate support is provided with a wedged step, the wedged steps are matched in a sliding manner, and the spring elastically contacts with the end face of the step of the squeezing support. Guide grooves are formed in the side surface of the floating support and the bottom surface of the squeezing support, and a side guide bolt and a bottom guide bolt respectively extend from the pressing plate support into the side guide groove of the floating support and the bottom guide groove of the squeezing support. A squeezing bolt penetrates the pressing plate support to squeeze the screw bolt. Upper parts on sliding tables are fixed through matching slopes of the floating support and the squeezing support, and vertically downward pressing force of the pressing plate is transformed into lower parts of the sliding tables, so that abrasion between sliders and guide rails in a sliding table device is effectively alleviated and the sliding table can be ensured to sustain precision for a long time.
Description
Technical field
The utility model belongs to field of machining, relates to a kind of hold down gag, relates in particular to a kind of float support and hold down gag.
Background technology
As everyone knows, carry out the machining of workpiece on Digit Control Machine Tool time, need to carry out clamping to workpiece.A kind of moving press plate device with fixed support of normal application in frock clamp, pressing plate function power acts directly on compacted workpiece vertically downward.For some special occasions, as in the time that the upper strata parts to machine tool sliding table device are locked, if use traditional moving press plate device, the active force of pressing plate can act directly on slide block and guide rail vertically downward, long-term use will be accelerated the wearing and tearing of slide block and guide rail, have a strong impact on the precision of guide rail, reduce its normal service life.Therefore,, in frock clamp application, need a kind of device of special fixing slide unit upper strata parts.
Utility model content
The utility model provides a kind of float support and hold down gag, avoid pressing plate thrust to act directly on from top to bottom on the parts of slide unit upper strata, better realize fixing slide unit upper strata parts, compact conformation, operate nimble, improve workpiece working (machining) efficiency, alleviated operator's labour intensity.
For realizing as above object, the technical solution adopted in the utility model is: a kind of float support and hold down gag, comprise that plate bearing, pressing plate, float support and jam-packed support; On plate bearing, have vertical direction and axial slideway, float support, jam-packed support and spring are installed in slideway; Double-screw bolt is takeed on hex nut by band pressing plate is fixed on plate bearing.
Float support in plate bearing and jam-packed support and are provided with wedge shape step, and both are slidably matched, the step end face that spring contact jam-packed supports.
Float support side, jam-packed support bottom surface and have gathering sill, and side guide screw and bottom surface guider screw put in float support side guide groove and jam-packed support bottom surface gathering sill from plate bearing respectively; Jam-packed screw is through plate bearing jam-packed double-screw bolt.
Owing to adopting technical scheme as above, the utlity model has following superiority:
The utility model compact conformation, operate nimble, on the cooperation inclined-plane that supports two parts by float support and jam-packed by fixing slide unit upper strata parts, pressing plate thrust is vertically downward changed in slide unit lower part, avoid pressing plate thrust to act directly between the slide block and guide rail of slide rest device, effectively slow down the wearing and tearing between slide block and guide rail in slide rest device, ensured that slide rest device can maintain precision for a long time.
Brief description of the drawings
Fig. 1 is the cross-sectional view of a kind of float support of the utility model and hold down gag.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is further described.As shown in Figure 1, a kind of float support and hold down gag, comprising: band shoulder hex nut 2, double-screw bolt 3, pressing plate 4, float support 5, jam-packed screw 6, side guide screw 7, spring 8, jam-packed support 9, plate bearing 10, bottom surface guider screw 11; On plate bearing 10, have vertical direction and axial slideway, float support 5, jam-packed support 9 and spring 8 are installed in slideway; Double-screw bolt 3 is takeed on hex nut 2 by band pressing plate 4 is fixed on plate bearing 10.
Float support 5 in plate bearing 10 and jam-packed support 9 and are provided with wedge shape step, and both are slidably matched, and spring 8 Elastic Contact jam-packeds support 9 step end face.Support 9 bottom surfaces at float support 5 sides, jam-packed and respectively have gathering sill, side guide screw 7 and bottom surface guider screw 11 put in float support 5 side guide grooves and jam-packed supports in 9 bottom surface gathering sills from plate bearing 1 respectively, and jam-packed screw 6 is through plate bearing 10 jam-packed double-screw bolts 3.
Its operation principle is: in the time compressing slide unit upper strata parts 1, take on the threaded engagement of hex nut 2 and double-screw bolt 3 by band, and the downward clamping platen 4 of band shoulder hex nut 2, pressing plate 4 drives float support 5 to move down.Meanwhile, utilize two characteristics that coordinate inclined-plane, jam-packed supports 9 and stretches out with moving down forward of float support 5, holds out against slide unit upper strata parts 1.Under the acting in conjunction of pressing plate 4 and jam-packed support 9, complete fixing slide unit upper strata parts 1.
Remove when slide unit upper strata parts 1 are fixed, only need unclamp band shoulder hex nut 2, jam-packed supports 9 and exits backward under the effect of spring 8 elastic restoring forces, promotes float support 5 and moves up, now pressing plate 4 leaves the contact-making surface of slide unit upper strata parts 1, completes the release to slide unit upper strata parts 1.
The utility model is simple to operate, and in the time realizing slide unit upper strata parts compression, loosen process, corresponding need tighten and loosen band and take on hex nut.
