Embodiment Construction

[0017] The present invention will be further described in detail below in conjunction with the accompanying drawings.

[0018] Such as figure 2 , 3 As shown in the figure, in the slider fine-tuning device of the four-column overhead oil cylinder press, two single-row tapered roller bearings 12 are installed at both ends of the worm 11 and locked with round nuts 9 and stop washers 10 respectively, and the two single-row tapered roller bearings The sub-bearing 12 is installed on the slide block 4, and the two ends are fixed with the first gland 8 and the second gland 13 respectively.

[0019] O-rings 7 are respectively embedded on the cylindrical surfaces of the first gland 8 and the second gland 13 to prevent the leakage of bearing lubricating oil.

[0020] The outside of the second gland 13 is equipped with a protective cover 14 to prevent misoperation at ordinary times, and can be removed when fine-tuning is required.

[0021] The eccentric worm gear 6 is installed on the...

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 [0001] The invention relates to a fine-adjustment device for a slide block of a four-column overhead oil cylinder press, in particular to a fine-adjustment device for a worm gear eccentric sleeve type slide block. Background technique [0002] At present, the parallelism between the lower plane of the slider of the domestic closed high-speed precision press and the plane on the worktable is generally adjusted through the mold height adjustment mechanism. The applicant's four-column overhead oil cylinder press has a mold height adjustment mechanism of the chain nut type, such as figure 1 Shown, mainly by adjusting nut (sprocket wheel) 16, chain 17 forms. When adjusting, first loosen the chain 17, and then fine-tune the heights of the four adjusting nuts (sprocket wheels) 16 on the column 18, so that the upper beam 15 drives the slider 4 to move up and down slightly, so as to achieve the purpose of adjusting the parallelism of the slider. This kind of fine-tu...
