Abstract
The utility model discloses a self-aligning structure for a jaw crusher toggle plate, which is characterized in that the self-aligning structure mainly consists of a regulating seat, a regulating block and a regulating pad plate, wherein the regulating seat is arranged in a machine frame casing, the regulating pad plate is arranged between the regulating seat and the machine frame casing, one side surface of the regulating seat is an arc-shaped concave surface, one side surface of the regulating block is an arc-shaped convex surface which is tightly abutted against the arc-shaped concave surface, the other side of the regulating block is provided with a fixing groove, one end of the toggle plate is arranged in the fixing groove of the regulating block, the other end of the toggle plate is supported on a groove of a movable jaw body, and one end of the toggle plate is fastened in the fixing groove of the regulating block through a toggle plate pad. An arc-shaped surface contact installing mode is adopted, and the real-time regulation on the position of the toggle plate can be realized, so the single-side abrasion of the toggle plate is reduced, and equipment is ensured to normally work. The self-aligning structure has the advantages that the structure is simple and reasonable, the processing position precision of seat holes of the machine frame casing and the like is reduced, the processing cost is undoubtedly reduced for large and medium-sized jaw crushers, and the equipment performance is improved.
Description
Technical field
The utility model relates to a kind of jaw crusher, specifically is a kind of automatic aligning structure of jaw crusher bracket.
Background technologyJaw crusher is called for short Hubei Province broken (having another name called the tiger mouth), it is big that well-known jaw crusher has the ratio of reduction, simple in structure, reliable operation, keep in repair easy, many characteristics such as operating cost is low, be mainly used in metallurgy, the mine, chemical industry, cement, building, various middle hard ore broken and in small, broken bits and rock were used during industrial department such as refractory material and pottery was done, its operation principle is: Motor Drive belt and belt pulley, by eccentric shaft jaw is moved up and down, angle becomes big between bracket and moving jaw when moving jaw rises, thereby it is approaching to fixed jaw to promote moving jaw plate, simultaneously material is crushed or split brokenly with it, reaches broken purpose; When moving jaw was descending, bracket and moving jaw angle diminished, and moving jaw plate under the effect of spring, leaves fixed jaw at pull bar, and this moment, broken material was discharged from the crusher chamber end opening.Broken motor-driven jaw is done the periodic motion crushing and is drained material along with continuous rotation of motor.
But in the process of fragmentation processing, uneven wear appears in bracket easily, and to a side play, can occur when serious just being solved the disconnected phenomenon in the screw of briquetting top effectively so must repeatedly revise bracket, has had a strong impact on operating efficiency.
The utility model content
In order to overcome above-mentioned deficiency, thereby the utility model purpose is to provide a kind of automatic aligning structure that can adjust the jaw crusher bracket that can guarantee operate as normal to the position of bracket in real time.
To achieve these goals, the technical solution adopted in the utility model is:
A kind of automatic aligning structure of jaw crusher bracket, it is characterized in that: it mainly is to constitute by adjusting seat, adjust piece and regulating backing plate, described adjustment seat is located in the frame housing, regulating backing plate is located between adjustment seat and the frame housing, a described side of adjusting seat is an arc-shaped concave, a side of adjusting piece be with arc-shaped concave near arc convex, the opposite side of adjusting piece is provided with holddown groove, one end of bracket is located in the holddown groove of adjusting piece, and the other end is bearing on the groove that moves on the gnathosoma.
Be provided with the bracket pad in the holddown groove of described adjustment piece, an end of bracket is fastened in the holddown groove of adjusting piece by the bracket pad.
The beneficial effects of the utility model: because the mode that adopts the arcwall face contact to install, thereby can realize the position of bracket is adjusted the uneven wear that reduces bracket in real time, the equipment that guaranteed can be worked normally; The utility model is simple and reasonable, has reduced the positional precision of processing such as frame housing seat hole, and this has reduced processing cost beyond doubt concerning big-and-middle-sized jaw crusher, improved the performance of equipment.
Description of drawings
The utility model is described in further detail below in conjunction with accompanying drawing.
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is shown in Figure 1 along A---the cutaway view of A line.
Among the figure: 1, bracket; 2, bracket pad; 3, adjust piece; 4, adjust seat; 5, regulate backing plate; 6, frame housing; 7, moving gnathosoma.
The specific embodiment
As shown in Figure 1, a kind of automatic aligning structure of jaw crusher bracket, it is characterized in that: it mainly is to constitute by adjusting seat 4, adjust piece 3 and regulating backing plate 5, described adjustment seat 4 is located in the frame housing 6, regulating backing plate 5 is located between adjustment seat 4 and the frame housing 6, a described side of adjusting seat 4 is an arc-shaped concave, a side of adjusting piece 3 be with arc-shaped concave near arc convex, the opposite side of adjusting piece 3 is provided with holddown groove, one end of bracket 1 is located in the holddown groove of adjusting piece 3, and the other end is bearing on the groove that moves on the gnathosoma 7.
Be provided with bracket pad 2 in the holddown groove of described adjustment piece 3, an end of bracket 1 is fastened in the holddown groove of adjusting piece 3 by bracket pad 2.
Operation principle: because the processing equal error, cause the certain deviation of parallel existence of moving gnathosoma upper groove and back bracket, the back is installed, still can guarantee contacting fully of bracket and moving gnathosoma upper groove because jaw breaks the effect of the automatic aligning structure of bracket.
Though described embodiment of the present utility model in conjunction with the accompanying drawings; but those skilled in the art can make various distortion or modification within the scope of the appended claims; as long as be no more than the described protection domain of claim of the present utility model, all should be within protection domain of the present utility model.
