specific Embodiment approach 1

[0033] DETAILED DESCRIPTION One: Combination Figure 1 to 16 In the present embodiment, the automatic surfaculating method of a mineral sprocket chain socket includes the following steps:

[0034] Step 1: Plan the welding torch walking path:

[0035] First, surface information is obtained; then the surface of the nest is multi-layer multi-channel stack; for a certain layer of surfacing, the solder torch is planned to fill the walking route on the solder torch; obtain the discrete point; for discrete points, Get the radiode information of the final surface of the final surface; determining the robot's push post during the surfacing process; transforming the path points and attitude information into the robot executing program file;

[0036] Step 2: Using the line structure light sensor to determine the user coordinate system:

[0037] Through the relationship between the pixel coordinate system S and the camera coordinate C, the integrated camera coordinate system C relative tool co...

specific Embodiment approach 2

[0039] DETAILED DESCRIPTION 2: Combination Figure 1 to 16 In this embodiment, the process of obtaining surface information in the steps of the present embodiment includes: first analyzing the morphological characteristics of the sprocket before designing the surfacing path, and the sprocket is made of more pairs of uniform distribution, the chain nest opposite The wheel tooth and the hollow hub are composed of the chain slot, and the shape is composed of a surface and a plane, which is a three-dimensional information characterized for each link surface, and the feature point O and the user coordinate system U (X, Y, Z), o Select the chain nest. The two boundary lines of the planar portion, extending along the two boundaries to the X-axis and the Y-axis, determine the Z axis according to the right hand law, to obtain the user coordinate system U (X, Y, Z), thereby obtaining two symmetric settings Surface information of the sleeve surface 1 and the link surface 2 2 relative to U (X,...

specific Embodiment approach 3

[0040] Specific Embodiment 3: Combination Figure 1 to 16 In the present embodiment, the process of multi-layer multi-tunnel surface is performed in the steps of the step of the step of the present embodiment, including: using software first, the surface of the unfilled linked socket is equivalent, and the slope surface The specific distance is shifted in the direction of each point of the phase vector direction, and then the new offset discrete point is screened, fitted to the surface of the initial strand surface specific offset distance. Use the contour surface of the required surfacing Curved layer Cut, remove the part of the edge, get the surface that eventually needs to be solder The technical features that are not disclosed in the present embodiment are the same as those of the specific embodiment.

[0041] In this embodiment, the SolidWorks software first is first equivalent to the surface surface of the unsolded linked socket.

Abstract

The invention discloses an automatic surfacing method for the surface of a chain pocket of a mine sprocket, which relates to the field of additive manufacturing. The invention aims to solve the problems of non-automation and low welding efficiency in the existing chain nest surfacing welding process. The invention includes planning the walking path of the welding torch; using the line structured light sensor to determine the user coordinate system: through the transformation relationship between the pixel coordinate system S and the camera coordinate system C, the comprehensive camera coordinate system C relative to the tool coordinate system T and the tool coordinate system T Relative to the relationship between the base coordinate system B, the conversion relationship between the final pixel coordinate system S and the base coordinate system B is obtained, and the transformation of the user coordinate system U relative to the base coordinate system B is realized; the coordinate transformation generates the final surfacing program. The invention is used for the arc surfacing treatment of the chain socket of the sprocket.

Description

Technical field [0001] The present invention relates to the field of additive manufacturing, and more particularly to a mineral sprocket lending surface surface automatic surfacing method. Background technique [0002] The mineral sprocket is an important part in the scraper conveyor, and the transmission of the chain meshed in the coal mining operation. Due to the friction between the sprocket and the chain, the influence of ore particles causes a serious abrasion, thereby requires sufficient wear resistance. The current common method is that the sprocket is integrated with high-strength medium carbon steel materials (42CRMO, etc.), and the material cost is high, resulting in waste, on the other hand, after high-strength steel is modulated, the surface hardness and wear resistance are not Get sufficient improvement, the life of the sprocket is limited. [0003] If wear-resistant material is solder in the linet, the substrate portion selects the conventional material capable of s...
