Description

Technical Field

[0001] The utility model relates to the technical field of wear-resistant tooth plates of mining crushers, in particular to a fixing structure for processing wear-resistant tooth plates of mining crushers. Background Art

[0002] Mining crushers are widely used in many sectors such as mining, smelting, building materials, highways, railways, water conservancy and chemical industries. Commonly used stone crushing machines include jaw crushers, impact crushers, air separation crushers, hammer crushers, impact crushers, roller crushers, compound crushers and cone crushers. When producing mining crushers, one of the important processes is to process the tooth plates used to crush materials. When processing the tooth plates, the original parts of the tooth plates need to be fixed first, so as to facilitate various processing operations such as grinding.

[0003] The utility model patent with publication (announcement) number: CN218078154U solves the problem that most of the current equipment used to fix the tooth plate only fixes the tooth plate in the horizontal direction, but often ignores the fixation in the vertical direction, which causes the tooth plate to shake easily during the processing. It drives two electric push rods to extend and drive two clamping plates to approach each other and clamp and fix the tooth plate. This method has a simple structure, but in actual use, when the clamping plate contacts one side of the teeth on the surface of the tooth plate, the contact area between the clamping plate and the teeth is small, so that the pressure on the contact surface is large, which can easily cause damage to the tooth plate. In addition, the small contact area between the clamping plate and the teeth will also lead to a decrease in the friction between the clamping plate and the tooth plate, which reduces the stability of the device clamping the tooth plate, and thus leads to poor clamping effect.
