Abstract
The utility model discloses a wallboard strengthening structure for a jaw crusher. The wallboard strengthening structure comprises two wallboards which are oppositely arranged and a movable jaw which is positioned between the wallboards, and the two wallboards which are oppositely arranged are connected and fixed together through a pull rod; the pull rod penetrates through a round hole in the middle part of the movable jaw, and the diameter of the round hole is larger than the diameter of the cross section of the pull rod; the two end parts of the pull rod are respectively provided with steps and threads which are matched with nuts; the steps of the pull rod are connected and fixed together with the insides of the wallboards; and the pull rod are sequentially connected and fixed together with the outer parts of the wallboards through bushes and the nuts. The wallboard strengthening structure has the beneficial effects that the pull rod is used for ensuring the strength and clearance dimension of the jaw crusher, a plurality of reinforcing ribs do not need to be welded at the two sides of the wallboards, so the wallboard deformation which is caused by welding is reduced; if a box is cast, the casting difficulty is lowered, and the casting cost is also reduced; the weight of the whole jaw crusher is reduced, and the cost of the crusher is lowered; and the pull rod structure can not only enhance the strength of the wallboards but also can better stabilize the clearance dimension of a crushing chamber.
Description
Technical field
The utility model belongs to mining machinery and manufactures and designs the field, especially belongs to jaw crusher and manufactures and designs the field, and particularly a kind of jaw crusher wallboard is strengthened structure.
Background technology
Jaw crusher is a kind of a kind of rock crushing plant of under adverse circumstances, working; It is when operation; Be directly broken thing to be crushed, and each accessory requirement of strength of disintegrating machine is very high when broken thing is crushed, the wallboard that is particularly impacted for a long time; Its intensity directly has influence on the service life of jaw crushed stone machine, and the security in operation process.
At present, jaw crusher adds that a lot of reinforcement gussets guarantee the intensity of jaw crusher when all being employed in welding of wallboard both sides or complete machine casting, and when operation, remains corresponding headroom size.The wallboard of welding casing and the material of gusset all are Q235.Yet when gusset is strengthened in too much welding; Can produce welding stress and distortion; Cause jaw crusher in the existing distortion more or less of welding rear wall plate, make its headroom size not reach requirement, the residual stress after the welding brings the influence on the intensity also can for whole jaw crusher.For casting box, the reinforcement gusset on wallboard both sides has increased the difficulty of casting, is easy at these local generation pore, slag inclusion, is not easy casting flaw and manufacture difficulty such as modeling, delivery.
Though strengthen intensity and headroom size that gusset can guarantee jaw crusher; But too much reinforcement increases the weight of the quality of its whole jaw crusher; Production cost rises, complex manufacturing, production cycle lengthening; Directly cause the production cost of jaw crusher to rise, and also cause difficulty to subsequent transportation etc.
Summary of the invention
The utility model discloses a kind of jaw crusher wallboard reinforcement structure according to the deficiency of prior art.The problem that the utility model will solve provides a kind of pull bar and connects fixed method reinforcement jaw crusher wallboard, is not rolling up the shock proof intensity of raising jaw crusher wallboard under the reinforcement slat element.
The utility model is realized through following technical scheme:
The jaw crusher wallboard is strengthened structure, comprises two wallboards that are oppositely arranged and the moving jaw between wallboard, it is characterized in that: it is fixing that two wallboards that are oppositely arranged have pull bar to connect.
Said pull bar passes the circular hole at said moving jaw middle part, and Circularhole diameter is greater than the pull bar cross-sectional diameter.
The screw thread that there is step at said pull bar both ends and cooperates with nut.
Said pull bar step is through the inboard location that connects of cushion block and wallboard.
Said pull bar is connected fixing with nut with the wallboard outside through lining successively.
Existing jaw crusher is conventional mine mechanism, realizes the fragmentation of material through the moving jaw of motor-driven.The utility model adopts pull bar to connect the jaw crusher wallboard, and pull bar has export-oriented step and fix through cushion block and wallboard are inboard, has strengthened the headroom size of crusher chamber, and the outer end is fixed through lining and nut and wallboard, and more stable, intensity is bigger.
In sum, intensity and the headroom size of the utility model through guarantee jaw crusher with pull bar has following excellent benefit property: need not to weld so much reinforcement in the wallboard both sides, reduced the distortion of welding to wallboard; If casting box has reduced the difficulty of casting, also lowered the cost of casting; Make the weight saving of whole jaw crusher, reduced the cost of machine; Tiebar structure can Reinfored wallboard intensity can be stablized the headroom size of crusher chamber again preferably.

The specific embodiment
Below in conjunction with specific embodiment and accompanying drawing the utility model is further specified.Embodiment is used to explain the utility model, limits the utility model never in any form.
In conjunction with Fig. 1 and Fig. 6.
The jaw crusher wallboard is strengthened structure, and it is fixing to comprise that wallboard 7 that two wallboards 7 that are oppositely arranged and the moving jaw 6, two between wallboard are oppositely arranged has pull bar 1 to connect.
The screw thread 1a that there is step 1b at said pull bar 1 both ends and cooperates with nut 4.
Processing is, on wallboard 7, joins and bores with the hole of lining 5 identical sizes, in order to fixing two bolts hole of cushion block 3, left and right sidesing wall plate 7 symmetrical processing.All there is the screw thread that cooperates with nut 4 at the two ends of pull bar 1, the screwed hole that two Kong Youyu bolts 2 of cushion block 3 cooperate.
When assembling, earlier cushion block 3 usefulness bolts 2 on one side are fixed on the wallboard 7, put on pull bar 1 then, lining 5 on cooperating, again with being fixed on another piece cushion block 3 on the wallboard 7 on other one side, with pneumatic impact spanner that nut 4 is urgent again.
Wherein pull bar 1 has enough concentricitys, and to guarantee the position degree between two wallboards, there is step 1b at pull bar 1 two ends, is the headroom size that guarantees between two wallboards 7 in order to cooperate with cushion block 3.Because jaw crusher utilizes spindle eccentricity to reach broken material so its stroke sub-elliptical.For prevent machine when running pull bar 1 interfere with moving jaw 6, when the moving jaw 6 of casting, consider its extreme position, wear pull bar 1 position and cast out circular hole so will move jaw 6, the one, prevent machine moving jaw 6 and pull bar 1 interference when running; The 2nd, reduced unnecessary waste, make the quality of moving jaw 6 alleviate, reduced the load on the eccentric shaft.
