The fine adjustment device is characterized by easy and convenient adjustment, high accuracy of fine adjustment, elimination of the connecting rod gap when the device is applied to a wide-table press machine, effectively improved deflection curve distribution of the slide block, lowered deflection peak value, and slide block parallelism error that meets requirements specified by a standard.
Description
Technical field
The utility model relates to a kind of four capitals and puts oil cylinder working-pressure machine slide block micromatic setting, the eccentric shell type slide block of particularly a kind of worm and gear micromatic setting.
Background technology
Present domestic straight side high speed precision press slide block lower plane generally all is to adjust through the high governor motion of mould to the depth of parallelism on plane on the working plate.The applicant's four capitals are put the oil cylinder working-pressure machine, and the high governor motion of its mould is the chain nut type, and is as shown in Figure 1, mainly are made up of adjusting nut (sprocket wheel) 16, chain 17.Unclamp chain 17 during adjustment earlier, again through finely tuning the height of four adjusting nuts (sprocket wheel) 16 on the column 18 respectively, it is micro-mobile about in the of 4 to make that entablature 15 drives slide block, to reach the purpose of the adjustment slide block depth of parallelism.This kind method for trimming can reach higher depth of parallelism adjustment precision when the two-point press upper table surface is narrower, but adjusts cumbersome.And on 4 machines that bear on, because the table top broad, the amount of deflection that the slide block distortion produces is bigger, and in order to eliminate the gap of connecting rod, the sag curve that improves slide block distributes, and is necessary to design a cover single glider micromatic setting, to guarantee the parallelism precision of slide block.
Summary of the invention
The utility model technical problem to be solved is for the above-mentioned defective of eliminating prior art a kind of press ram micromatic setting to be provided; Can realize the fine setting of the slide block depth of parallelism easily; The sag curve that improves slide block distributes; Not only adjust the precision height, and easy to adjust simple, thus guarantee punching precision, the raising workpiece quality of forcing press and prolong die life.
The utility model is to solve the problems of the technologies described above the technical scheme that adopts to be: four capitals are put oil cylinder working-pressure machine slide block micromatic setting; It comprises slide block, connecting rod, a worm screw, an eccentric worm gear, a bearing pin and an oilless bearing; The worm screw two ends are installed on the slide block respectively; Protective cover is housed, and eccentric worm gear is installed on the slide block and with worm screw and is meshed, and oilless bearing is pressed in the hole of connecting rod; In the eccentric inner hole of eccentric worm gear and the hole of oilless bearing bearing pin is housed, bearing pin and slide block are fastening with the housing screw that passes eccentric worm gear long slot bore.
The worm screw adjustable side also is provided with a protective cover.
When needs are finely tuned the depth of parallelism of slide block, unclamp the housing screw between bearing pin and the slide block earlier, pull down protective cover; Use the spanner rotary worm, drive eccentric worm gear rotation, the eccentric inner hole of eccentric worm gear rotates synchronously; Drive is contained in the bearing pin in the eccentric inner hole; Thereby make slide block move up and down, rotate to desirable value, tighten housing screw again, load onto protective cover and get final product.
Therefore on the above-mentioned slide block vertical arrows is set, corresponding eccentric worm gear end face is provided with dial, and the scale value of dial can be decided according to actual conditions, regulates according to worm gear end face scale, 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 make things convenient for rotary worm through general tool like this.
Above-mentioned slide block micromatic setting all is housed between each connecting rod place and slide block.
Compared with prior art, the advantage of the utility model is:
Through unclamping housing screw, rotary worm is secondary, drives to lock after eccentric worm turns over required angle, can adjust the depth of parallelism of slide block, makes its error meet the standard code requirement, regulates simple and convenient, the trimming precision height.
Between each connecting rod place and slide block, the slide block micromatic setting is housed all; Separate between every cover slide block micromatic setting, be applied on the 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 the amount of deflection peak value, makes the parallelism error of slide block reach the standard code requirement.

The specific embodiment
Embodiment describes in further detail the utility model below in conjunction with accompanying drawing.
Like Fig. 2, shown in 3; Four capitals are put oil cylinder working-pressure machine slide block micromatic setting; The two ends of its worm screw 11 are equipped with two single-row tapered roller bearings 12 respectively and are locked with round nut 9, stop washer 10 respectively; Two single-row tapered roller bearings 12 are installed on the slide block 4, and two ends are fixing with first gland 8 and second gland 13 respectively.
Be embedded with O-ring seals 7 respectively on the face of cylinder of first gland 8 and second gland 13, to prevent the leakage of bearing oil.
Eccentric worm gear 6 is installed on the 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 with the housing screw 3 that slide block 4 usefulness are passed eccentric worm gear 6 long slot bores.
As shown in Figure 4; Vertical arrows 41 is set on the slide block 4, and corresponding eccentric worm gear 6 end faces are provided with dial 61, and the scale value of dial 61 can be decided according to actual conditions; The scale value of dial 61 is every lattice 0.01mm in the present embodiment, so 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 make things convenient for rotary worm through general tool like this.
When needs are finely tuned the depth of parallelism of slide block, unclamp the housing screw 3 between bearing pin 2 and the slide block 4 earlier, pull down protective cover 14; With spanner rotary worm 11; Drive 6 rotations of eccentric worm gear, rotate to desirable value, tighten housing screw 3 again, load onto protective cover 14 and get final product according to its end face scale.
