Abstract
The invention discloses a fine adjustment device for a slide block of a four-column overhead oil cylinder press. The device comprises the slide block, a connecting rod, a worm, an eccentric worm wheel, a protective cover, a pin shaft and an oilless bearing, wherein the two ends of the worm are arranged on the slide block respectively; the protective cover is arranged; the eccentric worm wheel is arranged on the slide block and is engaged with the worm; the oilless bearing is pressed into a hole of the connecting rod; the pin shaft is arranged in an eccentric inner hole of the eccentric worm wheel and a hole of the oilless bearing; and the pin shaft and the slide block are fastened by using a forcing screw which passes through a long slotted hole of the eccentric worm wheel. The device is easy and convenient to adjust and high in fine adjustment accuracy and is applied to a wide-table press, so that a gap of the connecting rod can be eliminated, deflection curve distribution of the slide block is effectively improved, deflection peak is reduced, and the parallelism error of the slide block meets requirements specified by a standard.
Description
Technical field
The present invention relates to a kind of four column overhead oil cylinder press fine adjustment device for slide blocks, particularly a kind of worm and gear eccentric sleeve type fine adjustment device for slide block.
Background technology
The depth of parallelism of current domestic straight side high speed precision press slide block lower plane to plane on working plate is all generally to adjust by the high governor motion of mould.The applicant's four column overhead oil cylinder press, the high governor motion of its mould is chain nut type, as shown in Figure 1, is mainly made up of adjusting nut (sprocket wheel) 16, chain 17.When adjustment, first unclamp chain 17, then by finely tuning respectively the height of four adjusting nuts (sprocket wheel) 16 on column 18, make entablature 15 be with movable slider micro-mobile Shang Xia 4, to reach the object of adjusting the slide block depth of parallelism.This kind of method for trimming can reach the higher depth of parallelism and adjust precision in the time that two-point press upper table surface is narrower, but adjusts cumbersome.And on 4 force-applying press machines, because table top is wider, the amount of deflection that slide block distortion produces is larger, in order to eliminate the gap of connecting rod, the sag curve that improves slide block distributes, and is necessary to design a set of independently fine adjustment device for slide block, to ensure the parallelism precision of slide block.
Summary of the invention
Technical problem to be solved by this invention is the above-mentioned defect in order to eliminate prior art and a kind of press ram micromatic setting is provided, can realize easily the fine setting of the slide block depth of parallelism, the sag curve that improves slide block distributes, not only adjust precision high, and be easy to adjust simple, thereby ensure punching precision, the raising workpiece quality of forcing press and extend die life.
The present invention solves the problems of the technologies described above the technical scheme adopting to be: four column overhead oil cylinder press fine adjustment device for slide blocks, it comprises slide block, connecting rod, a worm screw, an eccentric worm gear, a bearing pin and an oilless bearing, worm screw two ends are arranged on respectively on slide block, protective cover is housed, eccentric worm gear is arranged on slide block and with worm screw and is meshed, oilless bearing is pressed in the hole of connecting rod, in the eccentric eccentric inner hole of worm gear and the hole of oilless bearing, bearing pin is housed, bearing pin and slide block are used through the housing screw of eccentric worm gear long slot bore fastening.
Worm screw adjustable side also arranges a protective cover.
In the time need to finely tuning the depth of parallelism of slide block, first unclamp the housing screw between bearing pin and slide block, pull down protective cover, use spanner rotary worm, drive eccentric worm gear rotation, the eccentric inner hole of eccentric worm gear synchronously rotates, drive is contained in the bearing pin in eccentric inner hole, thereby slide block is moved up and down, rotate to desirable value, then tighten housing screw, load onto protective cover.
On above-mentioned slide block, vertical arrows is set, corresponding eccentric worm gear end face arranges dial, and the scale value of dial can be determined according to actual conditions, regulates according to worm gear end face scale, therefore regulates more conveniently, and precision is higher.
Its adjustable side of above-mentioned worm screw is set to the rotatable shape of general tool, can facilitate rotary worm by general tool like this.
Above-mentioned fine adjustment device for slide block is all housed between each connecting rod place and slide block.
Compared with prior art, the invention has the advantages that:
By unclamping housing screw, rotary worm pair, drives eccentric worm to lock after turning over required angle, i.e. the depth of parallelism of adjustable slide, makes its error meet standard gauge provisioning request, regulates simple and conveniently, and trimming precision is high.
Fine adjustment device for slide block is all housed between each connecting rod place and slide block, separate between every cover fine adjustment device for slide block, be applied on wide-bed-type press brake surface pressure machine, can independently regulate, the convenient connecting rod gap of eliminating, the sag curve that effectively improves slide block distributes, and reduces amount of deflection peak value, makes the parallelism error of slide block reach standard gauge provisioning request.

Detailed description of the invention
Below in conjunction with accompanying drawing embodiment, type of the present invention is described in further detail.
As shown in Figure 2,3, four column overhead oil cylinder press fine adjustment device for slide blocks, the two ends of its worm screw 11 are equipped with respectively two single-row tapered roller bearings 12 and are locked with round nut 9, stop washer 10 respectively, two single-row tapered roller bearings 12 are arranged on slide block 4, and two ends are fixing with the first gland 8 and the second gland 13 respectively.
On the face of cylinder of the first gland 8 and the second gland 13, be embedded with respectively O-ring seals 7, to prevent the leakage of bearing oil.
Protective cover 14 is equipped with in the outside of the second gland 13, to prevent maloperation at ordinary times, need to finely tune time, can pull down.
Eccentric worm gear 6 is arranged on slide block 4 and with worm screw 11 and is meshed, oilless bearing 5 is pressed in the hole of connecting rod 1, its two end is fixing with screw and connecting rod 1, in the hole of eccentric worm gear 6 and oilless bearing 5, bearing pin 2 is housed, and bearing pin 2 is fastening through the housing screw 3 of eccentric worm gear 6 long slot bores with slide block 4 use.
As shown in Figure 4, vertical arrows 41 is set on slide block 4, and corresponding eccentric worm gear 6 end faces arrange dial 61, and the scale value of dial 61 can be determined according to actual conditions, in the present embodiment, the scale value of dial 61 is every lattice 0.01mm, and therefore the degree of regulation of this micromatic setting is higher.
Its adjustable side 15 of above-mentioned worm screw is set to the rotatable shape of general tool, sees Fig. 3, can facilitate rotary worm by general tool like this.
In the time need to finely tuning the depth of parallelism of slide block, first unclamp the housing screw 3 between bearing pin 2 and slide block 4, pull down protective cover 14, with spanner rotary worm 11, drive eccentric worm gear 6 to rotate, rotate to desirable value according to its end face scale, then tighten housing screw 3, load onto protective cover 14.
