AI Technical Summary
Technical Problem
The existing method of fixing jaw crusher liners is prone to loosening and falling off, affecting the continuity and stability of the equipment.
Method used
The double-bolt fixing structure is adopted. The first fastening bolt is engaged with the dovetail groove through the dovetail block, and the second fastening bolt is embedded and connected to the polygonal head through the positioning countersunk hole. Combined with the dovetail groove and mounting hole design of the wear-resistant liner, the liner can be installed stably.
Benefits of technology
It effectively prevents the liner from loosening and falling off, improves equipment reliability and stability, reduces maintenance costs, and enhances crushing efficiency and production benefits.

Abstract
The utility model relates to a lining plate fixing structure for a jaw crusher. The lining plate fixing structure comprises a fixed jaw plate, a movable jaw plate, a wear-resistant lining plate, a first fastening bolt and a second fastening bolt, a transverse dovetail groove is formed in the middle of the back surface of the wear-resistant lining plate, and a mounting hole is formed in the upper end of the wear-resistant lining plate; through holes are formed in the upper ends of the fixed jaw plate and the movable jaw plate. The head of the first fastening bolt is a dovetail block, is matched with the dovetail groove and is fastened with the nut after penetrating through the mounting through hole; and the second fastening bolts penetrate through the mounting holes and the through holes and then are fastened with the nuts, so that the lining plate is stably mounted, loosening and falling are prevented, and the reliability and stability of equipment are improved. The wear-resistant lining plate is integrally formed by die casting, and dovetail grooves and mounting holes are convenient and fast to process. The positioning counter bore enables the head of the second fastening bolt to be embedded and positioned, rotation displacement is prevented, and the head is prevented from directly participating in crushing operation. The positioning counter bore of the polygonal structure is matched with the head of the second fastening bolt, the contact area and friction force are increased, and the anti-loosening performance is improved.
