Abstract
The utility model discloses a pressure plate type impact frame of an impact crusher, which comprises impact plates, pressure plates and fixing plates, wherein connectors are arranged at the bottom of each impact plate; a groove is formed on one end surface of each impact plate; both end surfaces of each impact plate are inclined surfaces; and the connectors of the impact plates are in embedded connection with the fixing plates, and the grooves and the inclined surfaces of the impact plates are matched and fixed with the inclined surfaces of the pressure plates, so that the impact plates are fixed. In the utility model, less fastening bolts are used to enable the pressure plates to squeeze the impact plates, so that the inclined surfaces on both sides of the impact plates are tightly pressed against the inclined surfaces of the fixing plates; holes matched with the connectors are formed on the fixing plates of the impact frame, and the impact plates can be conveniently embedded in the holes, so that even if the pressure plates and the impact plates are loosened, the impact plates cannot fall off owing to the cooperation effect of the holes; mounted bolts are sunk in counter bores, so as to be prevented from being damaged; and the quantity and the assembling time of the bolts are greatly reduced, the production cost is saved, the stability of the equipment is increased, and the safety performance is improved.
Description
Technical field
The utility model belongs to mining machinery and manufactures and designs the field, especially belongs to impact breaker and manufactures and designs the field, and particularly the presser type of impact breaker counterattack frame manufactures and designs.
Background technology
Impact breaker is a kind of crushing mechanism that utilizes impact energy to come broken material.When material gets into the bar active region; Receive high speed impact and the fragmentation of bar; And make broken material tangentially throw to the counterpunch board of the crusher chamber other end at a high speed, be broken once more, bounce back into the bar active region from counterattack face again then and continue the repetition said process.In coming and going the way, the storeroom effect that runs foul of each other in addition.Because material receives the strike of bar, and the collision between mutually of the impact of counterpunch board and material, material constantly produces the crack, and is loose and cause pulverizing.When raw meal particle size during, just draw off from the machine bottom less than the slit between counterpunch board and the bar.Its outstanding advantage be the ratio of reduction big, can simplify production procedure, the output finished product presents cube, and does not have tension force and crack, is widely used in industries such as building materials, traffic, the energy, cement, mine, chemical industry.
Disintegrating machine, is changed the rapid wear attrition component at every turn and all need be dismantled more connecting bolt so the rapid wear attrition component is changed frequently because breaking strength is big, because the demounting bolt connection is local many, wastes time and energy very much.At present the counterpunch board on the counterattack frame connects through a large amount of bolts, changes counterpunch board and not only need dismantle more connecting bolt, usually also damages and dismantle difficulty because of connecting bolt is subject to the broken material bump, and very influence is changed the part effectiveness affects and produced use.
Summary of the invention
The utility model discloses a kind of presser type counterattack frame of impact breaker according to the deficiency of prior art.The problem that the utility model will solve provides the mount fixing structure of counterpunch board on a kind of impact breaker counterattack frame, and this structure reduces the use of connecting bolt in a large number, can conveniently realize changing the needs of counterpunch board.
The utility model is realized through following technical scheme:
The presser type counterattack frame of impact breaker comprises counterpunch board, pressing plate and fixed head, wherein:
There is connector said counterpunch board bottom surface, and the connector outer end is greater than connector and counterpunch board bottom surface link, and counterpunch board one end face is fluted, and the inclined-plane that tilts with respect to the bottom surface is arranged in the groove, and the counterpunch board both ends of the surface are the inclined-plane that tilts with respect to the bottom surface;
Said pressing plate cross section is trapezoidal, and the inclined-plane that trapezoidal waist constitutes cooperates with the counterpunch board inclined end face, and pressing plate has perforation to go up the counterbore of lower plane;
Said fixed head has the fixture that cooperates with counterpunch board and pressing plate, comprises the press strip on matching and fixing inclined-plane, the hole of matching and fixing connector and the bolt hole of matching and fixing pressing plate.
On the further said fixed head hole be useful on connector turnover big end and with the small end of connector matching and fixing.
Said connector is identical with the small end shape of hole matching and fixing.
It is trapezoidal that further said connector profile is dovetail.
Two connectors are arranged on said each counterpunch board.Said each pressing plate has the counterbore of lower plane in two perforations.Said pressing plate passes counterbore that connect to go up lower plane with bolt and is connected with fixed head and fixes, and the head of bolt is positioned at pressing plate counterbore pit.The fixture that said fixed head has plural groups to cooperate with counterpunch board and pressing plate, every group of fixture is through fixing four counterpunch boards of a pressing plate.
Aforementioned impact breaker is made up of parts such as feed hopper, preceding casing assembly, rear box assembly, runner assembly and lower box assemblies, and the counterattack frame is installed in runner limit in the casing.
Assembling the step of strikeing back frame is, the connector of counterpunch board is put into the big end that fixed head is used for the connector manhole appendix, promotes counterpunch board and moves to the small end with the hole matching and fixing, makes connection dignity embedding small end interior fixing; The counterpunch board groove is fixed with respect to the inclined-plane embedding fixed head press strip that the bottom surface tilts simultaneously; After all counterpunch boards are placed, pressing plate is placed between two counterpunch boards, the bolt hole of matching and fixing pressing plate aligns on the counterbore of pressing plate and the anti-fixed head; Through bolt, penetrate in the counterbore, tightening bolt is promptly accomplished the assembling of presser type counterattack frame again.
The helpfulness of the utility model: the utility model makes pressing plate extruding counterpunch board through less fastening bolt, and inclined-plane, counterpunch board both sides is squeezed on the inclined-plane of fixed head tightly; On counterattack frame fixed head, do the hole that cooperates with connector, counterpunch board can make things convenient in the embedded hole, even pressing plate and counterpunch board are loosening, because the mating reaction in hole can not fallen down yet; The squeezing action that the utility model utilizes embedding grammar and inclined-plane is counterpunch board fixedly, has reduced assembling bolt, and assembling bolt sinks in the bolt hole, and is not fragile; Practice thrift bolt quantity and installation time greatly, practiced thrift production cost, increased the stability of equipment, improved security performance.
