Abstract
The utility model discloses a rack connection structure of a jaw crusher. The rack connection structure of the jaw crusher comprises a plurality of bosses on front and rear racks and a plurality of connection holes in a wallboard, wherein the positions, number and sizes of the bosses are matched with those of the connection holes; a fastening ring is also arranged between the bosses and the connection holes; the outer circumferential surface of the fastening ring is matched with the inner circumferential surfaces of the connection holes; the inner circumferential surface of the fastening ring is matched with the outer circumferential surfaces of the bosses; the outer circumference of the fastening ring is tapered to a certain degree; the inner circumferences of the connection holes are tapered to be matched with the tapered outer circumference of the fastening ring. According to the rack connection structure of the jaw crusher, the wallboard is firstly connected with the front rack and the rear rack through the bosses and the connection holes and subsequently fastened with the front rack and the rear rack through bolts; meanwhile, by virtue of the fastening ring, the bosses are connected with the connection holes in interference fit, thereby guaranteeing that the racks form an integrated body all the time during operation and the connection between the wallboard and the front and rear racks is not loosened even during high-frequency vibration.
Description
Technical field
The utility model relates to a kind of frame of ore being carried out to preliminary broken jaw crusher, relates to specifically a kind of syndeton of frame.
Background technology
Jaw crusher is a kind of ore crusher the most generally using, conventionally by a frame and be placed in the power set in frame, the parts such as fixed jaw and sewing jaw form, its frame can be divided into two kinds of monoblock type and pin-connected panels conventionally, unit frame is generally monoblock cast and forms, because carrying out the less employing of metalworking to frame inside after casting, pin-connected panel frame generally includes front frame, back joint frame and be placed in two blocks of wallboards between front frame and back joint frame, front frame, between back joint frame and wallboard, be bolted, but because jaw crusher can be for a long time among the higher-order of oscillation when working, connecting bolt is very easy to be shaken pine, and jaw crusher is arranged among mine conventionally, operating personnel are difficult to the loose bolt that shakes to weigh fastening, although can pass through front frame, after being first fixed by welding between back joint frame and wallboard, carrying out bolt is connected again, but with practical application experience, welding cannot be resisted vibration at all, weld seam can be shaken and be held rapidly.
Utility model content
For overcoming above-mentioned defect, the utility model aims to provide between a kind of front frame, back joint frame and wallboard can not be connected because of the higher-order of oscillation frame connecting structure of the loose jaw crusher that shakes.
For achieving the above object, the technical solution adopted in the utility model is: a kind of frame connecting structure of jaw crusher, comprise the connecting hole on boss in several forward and backward frames and several wallboards, the position of described boss and connecting hole, quantity and size match.
Between described boss and connecting hole, be also provided with a dead ring, the outer circumference surface of described dead ring and the inner peripheral surface of connecting hole match, and the inner peripheral surface of described dead ring and the outer circumference surface of boss match.
The excircle of described dead ring has a tapering, and the inner periphery of described connecting hole has a tapering matching with dead ring.
Described dead ring has a compensation breach, and described compensation breach runs through the ring limit of dead ring.
The ring inner side of described dead ring also has the curved groove of helping of an indent, described in help curved groove to be positioned at the right opposite of compensation breach.
Adopted the frame connecting structure of the novel jaw crusher of this reality, by boss and connecting hole, wallboard and forward and backward frame are first coupled together, by bolt, be fastenedly connected again, simultaneously, by dead ring, make the interference fit that is connected between boss and connecting hole, guarantee that in the running, frame is as a whole all the time, can not make the pine that shakes that is connected between wallboard and forward and backward frame because of dither.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is syndeton cross-sectional view of the present utility model;
Fig. 3 is the local structure for amplifying schematic diagram of Fig. 2;
Fig. 4 is dead ring structural representation of the present utility model.
In figure: the forward and backward frame of 1-, 2-boss, 3-wallboard, 4-connecting hole, 5-dead ring, 6-compensates breach, and 7-helps curved groove.
The specific embodiment
As shown in Figure 1, the utility model discloses a kind of frame connecting structure of jaw crusher, its innovative point is mainly that it comprises the connecting hole 4 on boss in several forward and backward frames 12 and several wallboards 3, and described boss 2 matches with position, quantity and the size of connecting hole 4.Before wallboard 3 and forward and backward frame 1 being coupled together by connecting bolt, first boss 2 is inserted respectively in corresponding connecting hole 4, make wallboard 3 and forward and backward frame 1 form an integral body.Conventionally boss 2 is required to be interference fit with connecting hole 4, with guarantee between wallboard 3 and forward and backward frame 1 be connected not can be because of the vibration pine that shakes.
While being pressed into corresponding connecting hole 4 due to a plurality of boss 2, need adopt very large pressure simultaneously, cause assembling very inconvenient, for this reason, as shown in Figure 2, another innovative point of the frame connecting structure of jaw crusher of the present utility model is to be also provided with between described boss 2 and connecting hole 4 dead ring 5, the inner peripheral surface of the outer circumference surface of described dead ring 5 and connecting hole 4 matches, and the outer circumference surface of the inner peripheral surface of described dead ring 5 and boss 2 matches.Conventionally, the excircle of described dead ring 5 has a tapering, and the inner periphery of described connecting hole 4 has a tapering matching with dead ring 5, and common described tapering is 2 ± 0.5 degree.
Before assembling, first boss 2 is placed in connecting hole 4, then the microcephaly of dead ring 5 is pressed in the space between boss 2 and connecting hole 4 inwardly, and progressively compresses.In the process compressing, the pressure of 4 pairs of dead rings 5 of connecting hole is increasing, and dead ring 5 to center crimp, make dead ring 5 hold the boss 2 in it tightly, after the pressure compressing arrives to a certain degree, connecting hole 4, between dead ring 5 and boss 2, all formed interference fit, now, connecting hole 4, between dead ring 5 and boss 2, weld together, completed the preliminary connection location to frame, and then finally connect by connecting bolt, because wallboard 3 is with front, between afer bay 1, pass through connecting hole 4, interference fit between dead ring 5 and boss 2 firmly connects into an integral body, can be because of the vibration pine that shakes in jaw crusher running.
For dead ring 5 is more easily out of shape to center when being subject to the extruding of connecting hole 4, described dead ring 5 can also have a compensation breach 6, and described compensation breach 6 runs through the ring limit of dead ring 5.Meanwhile, for preventing that dead ring 5 is because being out of shape excessive breaking, be also that the ring inner side of described dead ring 5 also has the curved groove 7 of helping of an indent in order to make dead ring 5 be easier to distortion, described in help curved groove 7 to be positioned at the right opposite of compensation breach 6.
