Abstract
The utility model discloses a fastening and positioning device for mobile jaw copper bushes of a jaw crusher. The fastening and positioning device comprises a portal steel frame, compacting devices mounted on two side arms of the portal steel frame, and a fixed bracket, wherein the portal steel frame is connected with the fixed bracket; each compacting device comprises a compacting screw rod and a nut; the nuts are fixed in holes on the side arms of the portal steel frame; the compacting screw rods are matched with the nuts; and the compacting screw rods are in contact with pressure plates. Since the two side arms of the portal steel frame are respectively arranged on the outer edges of the two movable jaw copper bushes of the jaw crusher, at the same time, the compacting screw rods in the compacting devices on the two side walls of the portal steel frame are tightened, and the two movable jaw copper bushes are jacked tightly through the pressure plates, so that the movable jaw copper bushes can be fixed in the axial direction effectively, which avoids the phenomena that the copper bushes leap in the axial direction, and are excessively worn, cracked and damaged.
Description
Technical field
The utility model relates to mining machinery, relates in particular to the fastening positioning device of the motor-driven jaw copper sheathing of jaw crushing.
Background technology
Jaw crusher is widely used in the mine, has big, the output advantages of higher of crushing.But, when the broken ore deposit that jaw crusher carries out former iron ore produces,, in ore breaking process, make the moving jaw of disintegrating machine partly receive very big load because the granularity of the tcrude ore that comes out of steamer is bigger, be prone to cause equipment breakdowns such as moving jaw main shaft copper sheathing wearing and tearing, gland craze and transfiguration.Especially in recent years; Along with the further release of ore production capacity, the continuous quickening of rhythm of production, jaw crusher prolongs running time; Broken ore deposit amount increases; Cause the fastening bolt silk tooth of the fixation clip on the moving jaw copper sheathing end face to cross quick-wearing, even the bolt fracture phenomenon occurs, cause copper sheathing overground, the cracking damage of play vertically.Like this, the moving jaw copper sheathing of disintegrating machine is changed frequent, and production cost is improved.And all must take the moving jaw position jaw copper sheathing that more moves apart at every turn, and workload is big like this, the activity duration is long, and input cost is big.
Summary of the invention
The utility model problem to be solved provides a kind of fastening positioning device of the motor-driven jaw copper sheathing of jaw crushing, and it can prevent effectively that copper sheathing from moving vertically, avoids the copper sheathing generation that play is overground vertically, cracking damages phenomenon.
The fixture of the motor-driven jaw copper sheathing of the utility model jaw crushing is characterized in that: it comprises gantry steelframe, is contained in hold down gag, fixed support on the steelframe two side arms of gantry, and gantry steelframe links to each other with fixed support.
Wherein, hold down gag comprises clamping screw, nut; Nut is fixed in the hole of gantry steelframe side arm, and clamping screw matches with nut, and clamping screw contacts with pressing plate on being fastened on moving jaw copper sheathing.
This novel whole device is fixedly connected with crusher frame through fixed support.Because the two side arms of gantry steelframe is respectively on the outer edge of two moving jaw copper sheathings of disintegrating machine; Tighten up the clamping screw in the steelframe two side arms hold down gag of gantry simultaneously; Hold out against two moving jaw copper sheathings through pressing plate; Can live moving jaw copper sheathing at axial restraint effectively, thereby avoid the copper sheathing generation that play is overground vertically, cracking damages phenomenon.
Description of drawings
Fig. 1 is the structural representation of the fastening positioning device of the motor-driven jaw copper sheathing of the utility model jaw crushing.
The specific embodiment
Can know from Fig. 1, the fastening positioning device of the motor-driven jaw copper sheathing of the utility model jaw crushing, it comprises gantry steelframe 1, is contained in hold down gag, fixed support 2 on gantry steelframe 1 two side arms, and gantry steelframe 1 links to each other with fixed support 2.
Hold down gag comprises clamping screw 3, nut 4; Nut 4 is fixed in the hole of gantry steelframe 1 side arm, and clamping screw 3 matches with nut 4, and clamping screw 3 contacts with pressing plate 6.
As this novel a kind of optimal way, clamping screw 3 is a sphere with the contact-making surface of pressing plate 6.Like this, even two contact-making surfaces wear and tear to some extent, can guarantee well that also clamping screw 3 is pressed on the pressing plate 6.
This novel whole device is fixedly connected with crusher frame 9 through fixed support 2.
Like this, amount increases when broken ore deposit, causes 8 teeth of fastening bolt of fixation clip 6 to cross quick-wearing; Even when bolt 8 phenomenon of ruptures occurring; Because the two side arms of gantry steelframe 1 on the outer edge of two moving jaw copper sheathings 5 of disintegrating machine, is tightened up the clamping screw 3 in gantry steelframe 1 two side arms hold down gag respectively simultaneously, holds out against two moving jaw copper sheathings 5 through pressing plate 6; Can live moving jaw copper sheathing 5 at axial restraint effectively, thereby avoid copper sheathing 5 generation that play is overground vertically, cracking damages phenomenon.Because moving jaw copper sheathing 5 need not frequent change, has improved equipment operating efficiency, has reduced production cost.
