Description

Technical Field

[0001] The utility model relates to the technical field of welding spatter removal equipment, in particular to a welding spatter removal device for structural parts of engineering machinery products. Background Art

[0002] Engineering machinery products are a general term for construction machinery used in engineering construction. They are widely used in construction, water conservancy, electricity, roads, and other engineering fields, such as skid loaders, backhoe loaders, excavators, bulldozers, mining machinery and other products. The structural parts of engineering machinery products are the skeleton of engineering machinery products, and they are the main load-bearing components. At the same time, they are the basic parts of other professional systems of the whole machine. The engine, electrical components, hydraulic components, etc. are all installed and laid out based on the structural parts of the whole machine. The structural parts are mainly divided into the following categories: frame: such as the frame of the skid loader, the main frame of the bulldozer, etc.; crawler frame: such as the crawler frame of the crawler skid loader, the trolley frame of the bulldozer, the crawler beam frame of the excavator, etc.; arm: such as the boom and rocker arm of the skid loader, the boom and bucket arm of the excavator, the digging arm and lifting arm of the backhoe loader, etc.; slewing control platform: such as the slewing platform of various excavators; bucket: such as the bucket of the loader, the digging bucket of the excavator, the bulldozer of the bulldozer, etc. The manufacturing process of structural parts for engineering machinery products mainly processes various types of panels, supports and other components into the required product structure through welding. The welding spatter formed during the welding process of structural parts will inevitably fall onto the surface of the components. In order to make the surface of the structural parts smooth and flat, removing the welding spatter has become an important and indispensable step in the welding process.

[0003] At present, the commonly used method for removing welding spatter is to repeatedly strike the end of the chisel with a hammer to make the chisel produce a force to scrape away the spatter, thereby removing the spatter on the surface of the component. This method has the risk of the hammer hitting the side and injuring people during the operation process; at the same time, the length of the chisel is relatively short, and the applicable position for removing spatter on the surface of the component is limited. In addition, the hammer is heavy, and the operator is easily fatigued after a long time of operation, and the removal efficiency is low. Utility Model Content

[0021] Example

[0022] like Figure 1-4 As shown, a device for removing welding spatter from a structural part of an engineering machinery product is mainly composed of a sleeve 1 and a core rod 2; wherein, a second cleaning head 11 is provided at one end of the sleeve 1 away from the core rod 2, the second cleaning head 11 is in a block structure, and the width of the second cleaning head 11 at one end close to the sleeve 1 matches the diameter of the sleeve 1, and the width gradually increases from the end close to the sleeve 1 to the outer end, the second cleaning head 11 is processed by using a waste machine tool handle, and a tool handle end face is formed on the second cleaning head 11, which fits and moves between the large plane of the component, and transmits mutual force to it when contacting the welding spatter on the surface of the component, so as to realize spatter removal.

[0023] The core rod 2 includes a support portion 21 and a connecting portion 22 embedded in the sleeve 1. The end of the support portion 21 away from the limiting assembly 23 is provided with a first cleaning head 24. The first cleaning head 24 includes an end 241 connected to the support portion 21 and two working inclined surfaces 242 symmetrically arranged along the central axis of the end 241. The distance between the two working inclined surfaces 242 gradually increases from the upper end of the end 241 to the lower end of the end 241. A limiting assembly 23 is provided between the support portion 21 and the connecting portion 22. The limiting assembly 23 is a sleeve 2 31, the longitudinal section of the sleeve 231 is arranged in a trapezoidal structure, the inner diameter of the sleeve 231 matches the outer diameter of the core rod 2, the outer diameter of the sleeve 231 close to one end of the sleeve 1 is larger than the inner diameter of the sleeve 1, and the sleeve 231 is fixed at a suitable position on the core rod 21 by welding; the support portion 21 and the end head 24 are assembled by butt welding and then ground to a smooth transition, and the sleeve 231 is welded on the top of the support portion 21, and then the outermost sleeve 231 and the connecting portion 22 are connected by a circumferential fillet weld and then ground to a smooth transition to form an embedded core rod. Axial conduction is achieved through the cooperation between the sleeve 1 and the core rod 2, and the step end face of the limiting component in the middle of the core rod 2 is used to realize the limit and force surface of the mutual conduction process between the sleeve 1 and the core rod 2. The exposed ends of the sleeve 1 and the core rod 2 are respectively processed into block and chisel shapes using waste machine tool handles and taps, thereby forming a guide pin-matched spatter removal tool; the sleeve 1 moves back and forth on the connecting portion 21 of the core rod 2 and knocks against each other to form a mutual force, and at the same time, the end face of the tool handle or the working bevel 242 is brought into contact with the welding spatter on the surface of the component, The force is transmitted to the welding spatter, thereby playing a role in removing the spatter.

[0024] The welding spatter removal device transmits the force through the guide pin matching method, which can effectively avoid the safety risk of the operator's hand being hit due to the deviation of the force position during the knocking process. At the same time, it greatly reduces the efficiency of the force transmission process, avoids energy loss, and improves work efficiency.

[0025] During the use of the tool, the connecting part 22 of the core rod 2 is embedded in the sleeve 1, and the working bevel 242 moves along the surface of the component or the corner position to achieve contact with the welding spatter and transmit the force; the sleeve 1 moves back and forth relative to the core rod 2 and knocks against each other to form a force and transmit it to the welding spatter on the surface of the component, thereby achieving the effect of removing the welding spatter.
