Description

Technical Field

[0001] The invention relates to the technical field of crusher blade inspection, and in particular to a crusher blade inspection device. Background Art

[0002] The crusher blade rotates in the crusher box with a large torque. If the crusher blade is deformed or the thickness of the cladding layer of the crusher blade is unqualified, the crusher blade will interfere with the box when it is installed in the crusher box. In serious cases, the structure of the entire crusher will be damaged. Therefore, when installing the crusher blade into the crusher box, it is necessary to detect the size and shape and position tolerance of the crusher blade to avoid damage to the crusher due to problems with the size and / or shape and position tolerance of the crusher blade.

[0003] In order to avoid the size and shape tolerance of the crusher blade not meeting the use requirements, the thickness of the cladding layer and the distance between adjacent cladding layers are currently mainly measured using a ruler. This can only ensure that the size and shape tolerance of the measuring point meet the requirements, but cannot ensure that the size and shape tolerance of the entire crusher blade meet the requirements. Summary of the invention

[0004] The purpose of the present invention is to provide a crusher blade inspection device, which can detect the size and shape and position tolerance of the crusher blade's cladding layer to avoid damage to the crusher due to the size and shape and position tolerance of the crusher blade's cladding layer not meeting the use requirements.

[0005] The technical solution adopted by the present invention is specifically as follows:

[0006] A crusher blade inspection device comprises a base, on which at least one crusher blade and at least two inspection components are arranged, and the inspection components are used to inspect the thickness of the cladding layer of the crusher blade.

[0007] As a preferred embodiment of the above scheme, a cutter shaft is further provided on the base, the cutter shaft is rotatably connected to the base, and at least one of the crusher blades is detachably connected to the cutter shaft.

[0008] As a preferred embodiment of the above scheme, a first connecting member and a second connecting member are further provided on the base, and two ends of the knife shaft are rotatably connected to the first connecting member and the second connecting member respectively.

[0009] As a preferred embodiment of the above solution, at least two of the inspection components are connected to the base via a connecting rod.

[0010] As a preferred embodiment of the above scheme, each of the inspection components includes a positioning sleeve sleeved on the connecting rod, and an inspection piece rotatably connected to the positioning sleeve.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] The inspection device for crusher blades disclosed in the present invention comprises a base, on which at least one crusher blade and at least two inspection components are arranged, and the inspection components are used to inspect the thickness of the surfacing layer of the crusher blade, so as to inspect whether the thickness of the surfacing layer of the crusher blade is qualified, thereby avoiding damage to the crusher due to unqualified thickness of the surfacing layer of the crusher blade.

[0013] The above description is only an overview of the technical solution of the present invention. In order to more clearly understand the technical means of the present invention, it can be implemented in accordance with the contents of the specification. In order to make the above and other purposes, features and advantages of the present invention more obvious and easy to understand, the following specifically cites a preferred embodiment and describes it in detail with the accompanying drawings as follows.
