Abstract
The utility model discloses a device for adjusting and fixing an impact rack of an impact crusher, comprising a disc spring (or an elastic element, such as spring and the like) positioned between an adjusting sleeve and a stander shell, threaded connection is formed between the adjusting sleeve and a hanger bolt, a positioning device is arranged between the adjusting sleeve and a tailor-made nut, the upper part of the adjusting sleeve is provided with a positioning device which rotates during adjustment, and the hanger bolt can move up and down by rotating the adjusting sleeve, so that the adjustment of the impact rack can be realized. The threaded connection is formed between the adjusting sleeve and the tailor-made nut. The adjusting sleeve is provided with a boss used for positioning the spring compressed to a certain degree. The adjusting method is as follows: the adjusting sleeve is rotated, and the upper part of the adjusting sleeve is provided with a clamping groove used during rotation. The compression of the spring remains unchanged all along.
Description
Technical field
The utility model relates to a kind of adjusting device of impact crusher, especially is applicable to the regulation fixing apparatus of the counterattack frame of impact crusher.
Background technology
Present employed impact crusher, fixed form such as Fig. 1 of the regulation fixing apparatus of its frame and counterattack frame, shown in Figure 2, counterattack frame 6 tops cooperate with suspended axle 7, sling and strike back frame 6, the two ends of suspended axle 7 are fixed on the two side of frame housing 5, counterattack frame 6 bottoms and hanger bolt 2 link up by bearing pin 11 and back-up ring 10 and split pin 9, adjusting nut 3 connects with hanger bolt 2, counterattack frame 6 is lifted on the frame housing 5, the contact-making surface of adjusting between nut 3 and the packing ring 8 is a sphere, weld together between packing ring 8 and the frame housing 5, spring 4 flexible members such as (or) dish springs is between frame housing 5 and hanger bolt 2, and spring 4 compresses counterattack frame 6 by compressing hanger bolt 2.Protective nut cover 1 screw thread that can protect hanger bolt 2 to expose is not subjected to accidental damage.During hydraulic cylinder 12 work, can reduce labour intensity.Impact crusher is in service at breaking ores, counterattack frame 6 is constantly impacted, the position that needs to adjust counterattack frame 6 behind the work certain hour, after counterattack frame 6 is adjusted downwards, since the spatial variations of compression spring 5, and the pressure of spring 4 is diminished, more there is spring 4 very just not play buffering and pressurization, be easy to cause counterattack frame 6 to damage, production can't normally be carried out.
Summary of the invention
The purpose of this utility model provides a kind of counterattack frame regulation fixing apparatus of impact crusher at above-mentioned the deficiencies in the prior art.
For achieving the above object, the utility model can be taked following technical proposals:
The counterattack frame regulation fixing apparatus of impact crusher described in the utility model, it comprises is adjusting dish spring between cover and frame housing flexible members such as (or) springs, between adjustment cover and hanger bolt, be provided with thread connection, adjust between cover and the special nut and be provided with positioner, the top of adjusting is provided with the positioner of rotation when adjusting, rotate the adjustment cover hanger bolt is moved up and down, thereby realize the adjustment of counterattack frame.
Be provided with thread connection between described adjustment cover and the special nut.
Described adjustment puts and is provided with boss, is used for the location of amount of spring compression.
Described method of adjustment is will rotate to adjust cover, and the top of adjusting cover is provided with the draw-in groove of using when supplying to rotate.
Described amount of spring compression remains constant.
The beneficial effects of the utility model are can effectively protect fixture not because of the impact of equipment produces loosening or damage, thereby guarantee ordinary production; increase work efficiency, reduce the consumption of disintegrating machine spare part, in addition; this is simple in structure, and I﹠M is convenient, can save time and cost.
