Abstract
The utility model relates to an adjustable hammer fixing device for an impact crusher and belongs to the technical field of devices for crushing stones in a mine. The adjustable hammer fixing device consists of a cast steel rotor end face plate, hammer pillows, hammers, wedge-shaped blocks, wedge-shaped extrusion blocks and locking bolts; the hammers are arranged in installation grooves of the cast steel rotor end face plate; one side of each hammer is provided with the hammer pillow, and the other side of each hammer is provided with the wedge-shaped extrusion block; and the wedge-shaped blocks are fixed on the wedge-shaped extrusion blocks. Due to the adoption of the structure of the wedge-shaped blocks and screw tightening devices, the tightness of screws is adjusted so as to slide the wedge-shaped blocks and fulfill the aim of adjusting the tightness of the impact hammers. The adjustable hammer fixing device is convenient to use and maintain, the hammers can be adjusted to be used, the effective using areas of the hammers are increased, and the areas of parts of the hammers, which are supported by the hammer pillows, are increased, so that the hammers cannot be cracked easily, and production cost is reduced. The problems that when a structure that the hammers are fixed by arranging iron plates on S-shaped shim plates is used in the conventional impact crusher, the tightness of the impact hammers cannot be adjusted, a rotor is easy to crack, the hammers cannot be conveniently replaced after being worn, and the maintenance cost is increased can be solved.
Description
Technical field
The utility model relates to a kind of adjustable tup fixture of impact breaker, belongs to mine lithotripsy apparatus technical field.
Background technology
What the counterattack tup fixture that at present domestic impact breakers use adopted is the parallels by a kind of S type, adds the fixing structure of iron plate on both sides.This fixture can't be regulated the degree of tightness of counterattack tup, causes the rotor attenuation of parallels part, and rotor is ruptured easily; And can not adjust after the tup wearing and tearing; It is also very inconvenient to change tup, causes use, maintenance and repair cost to increase, thereby the whole production cost is increased.
Summary of the invention
The purpose of the utility model is; An a kind of wedge and one group of bolt tightening device of between rotor and tup, passing through is provided; Can wedge be slided through regulating the bolt degree of tightness, reach the purpose of regulating counterattack tup degree of tightness, and can reverse end for end to use behind the surface wear of counterattack tup; Maintenance and repair is convenient, has increased effective usable floor area and the Area of bearing of hammer pillow to tup of tup, makes the not adjustable tup fixture of the impact breaker of easy fracture of tup.
The utility model is to realize above-mentioned purpose through following technical scheme:
The adjustable tup fixture of this impact breaker is made up of cast steel rotor-end face, hammer pillow, tup, wedge, wedge shape crushing block, clamping screw; It is characterized in that: tup places in the mounting groove of cast steel rotor-end face; One hammer pillow is housed in the mounting groove of tup one side; One wedge shape crushing block is housed in the mounting groove of tup opposite side, and the bottom of wedge is fixed on through clamping screw and is installed on the wedge shape crushing block of cast steel rotor-end face both sides; The two sides of tup up and down symmetry respectively are manufactured with a trapezoidal fixed strip, and the hammer pillow is welded on the cast steel rotor-end face, respectively are manufactured with a dovetail groove that cooperates with trapezoidal fixed strip on hammer pillow and wedge and the one side tup applying.
The utility model beneficial effect compared with prior art is:
The adjustable tup fixture of this impact breaker is to adopt a wedge to add the structure of one group of screw tightening device, through the adjusting screw(rod) degree of tightness wedge is slided, and reaches the purpose of regulating counterattack tup degree of tightness; And can reverse end for end to use after the wearing and tearing of counterattack tup.Make maintenance and repair more convenient, and increased effective usable floor area and the Area of bearing of hammer pillow of tup, make not easy fracture of tup, thereby reduced production cost tup.The parallels that has solved existing impact breaker use S type adds the fixing structure of iron plate, and the degree of tightness that can't regulate the counterattack tup causes the rotor attenuation of parallels part; Rotor is ruptured easily; And can not adjust after the tup wearing and tearing, it is inconvenient to change tup, increases the problem of maintenance and repair cost.
Description of drawings
Fig. 1 is installed in the structural representation on the cast steel rotor-end face for a kind of adjustable tup fixture of impact breaker;
Fig. 2 is installed in the structural representation on the main shaft for a kind of cast steel rotor-end face of adjustable tup fixture of impact breaker;
Fig. 3 is a kind of front partial enlarged drawing of adjustable tup fixture of impact breaker;
Fig. 4 is a kind of side partial enlarged drawing of adjustable tup fixture of impact breaker.
Among the figure: 1, cast steel rotor-end face, 2, hammer pillow, 3, tup, 4, wedge, 5, the wedge shape crushing block, 6, clamping screw, 7, trapezoidal fixed strip, 8, dovetail groove, 9, main shaft.
The specific embodiment
The adjustable tup fixture of this impact breaker is made up of cast steel rotor-end face 1, hammer pillow 2, tup 3, wedge 4, wedge shape crushing block 5, clamping screw 6; Tup 3 places in the mounting groove of cast steel rotor-end face 1; One hammer pillow 2 is housed in the mounting groove of tup 3 one sides; One wedge shape crushing block 5 is housed in the mounting groove of tup 3 opposite sides, and the bottom of wedge 4 is fixed on through clamping screw 6 and is installed on the wedge shape crushing block 5 of cast steel rotor-end face 1 both sides.The two sides of tup 3 up and down symmetry respectively are manufactured with a trapezoidal fixed strip 7, and hammer pillow 2 is welded on the cast steel rotor-end face 1, respectively are manufactured with a dovetail groove 8 that cooperates with trapezoidal fixed strip 7 on hammer pillow 2 and wedge 4 and the one sides that tup 3 is fitted.
The steady job process of the adjustable tup fixture of this impact breaker is: tup 3 is placed in the mounting groove of cast steel rotor-end face 1; To hammer the both sides that pillow 2 and wedge 4 are placed on tup 3 again into shape; And will hammer pillow 2 into shape and work good with the trapezoidal fixed strip 7 of tup 3 both sides with the dovetail groove 8 on the wedge 4, regulate the clamping screw 6 of wedge shape crushing block 5 then, when tightening up clamping screw 6; Two wedge shape crushing blocks 5 inwardly close up; Wedge 4 is upwards slided, and the slit that makes tup 3, wedge 4, hammer pillow 2 and cast steel rotor-end face 1 diminishes and will hammer and rest the head on 2 and be clamped in the mounting groove of cast steel rotor-end face 1, reaches the effect of the tup 3 that is fixedly clamped; After being fixedly mounted on tup 3 on the cast steel rotor-end face 1, can driving cast steel rotor-end face 1 by main shaft 9 and carry out fragmentation work.In the time will unclamping tup 3, unclamp clamping screw 6,4 of wedges make the slit between cast steel rotor-end face 1 and the tup 3 become big to lower slider, and tup 3 is released, just can carry out the work of the face that changes or the replacing tup 3 of tup 3.
The above is the specific embodiment of this utility model; The above-mentioned flesh and blood that illustrates not the utility model constitutes restriction; Under the those of ordinary skill of technical field after having read this specification, can make an amendment or be out of shape the above-mentioned specific embodiment, and do not deviate from the essence and the scope of the utility model.
