Description

Technical Field

[0001] This utility model relates to the field of mining machinery and equipment processing technology, specifically a welding device for mining machinery and equipment. Background Technology

[0002] Welding is a manufacturing process and technology that joins metals or other thermoplastic materials by heating, high temperature, or high pressure. Mining machinery and equipment are machines directly used in mineral mining and beneficiation operations. In the manufacturing process of mining machinery and equipment, materials of different shapes need to be fixed into an integrated structure by welding. Therefore, in the manufacturing of mining machinery and equipment, it is usually necessary to weld some parts. However, the welding equipment used in existing mining machinery and equipment is generally equipped with an operating platform and uses a welding torch for direct welding. Due to the lack of necessary clamping and fixing devices, when welding workpieces, the workpieces are not fixed and are prone to slippage or shaking during welding, resulting in welding misalignment, which greatly affects the welding efficiency and welding quality.

[0003] A search revealed a patent document with authorization announcement number CN217253932U, which discloses a welding device for manufacturing mining machinery and equipment. The device includes a workbench assembly, a fixing assembly, and a heat dissipation assembly. The fixing assembly comprises four fixed components, each including threaded sleeves evenly fixed at the four corners of the upper surface of the workbench. Each threaded sleeve has a threaded rod internally connected to it. A support member is rotatably mounted on the upper end of the threaded rod, and a limiting plate is fixedly mounted on the upper end of the support member. A pressure plate is sleeved between the limiting plate and the support member. The threaded rod drives the pressure plate to descend, thus pressing the workpiece. A waist hole is provided on the pressure plate to facilitate adjustment of the extended length of the pressure plate, allowing for pressing of different components. During pressing, the limiting rod is inserted into a limiting block, improving the stability of the pressing.

[0004] Based on the patent documents retrieved, the main method involves using four fixing components to hold the mining machinery to be welded. In actual operation, these four fixing components need to be adjusted. To facilitate the fixing of mining machinery with different structures, improve welding efficiency and quality, and prevent workpiece slippage or shaking during welding, which could cause welding misalignment, it is essential to provide a welding device different from existing technologies to solve the aforementioned problems and better meet the usage requirements of mining machinery.

[0026] Furthermore, in the welding device described in this utility model, the telescopic mechanism 3 includes a hydraulic telescopic rod 31 and a connecting block 32.

[0027] The clamping mechanism 4 includes a bidirectional lead screw 41, an internal thread moving block 42, and a fixing assembly. An opening slot 33 is provided in the connecting block 32.

The two internal thread moving blocks 42 are located at opposite ends of the bidirectional lead screw 41, and a fixing assembly is provided in each internal thread moving block 42. The fixing assembly includes an electric push rod 44 and a pressure plate 45. The electric push rod 44 is fixed in the internal thread moving block 42, and the pressure plate 45 is fixed to the output end of the electric push rod 44.

[0028] The clamping mechanism 5 includes a second bidirectional lead screw 51, an internal threaded slider 52, a support block 53, and a clamping plate 54.

[0029] Furthermore, in the welding apparatus described in this embodiment, to prevent damage to the surface of the workpiece to be welded caused by the pressure plate 45 and the clamping plate 54, a rubber plate 46 is provided on the bottom surface of the pressure plate 45, and a rubber plate 56 is fixed on the opposite sides of the two clamping plates 54 respectively.

[0030] like Figure 3As shown, this embodiment is based on Embodiment 1, and aims to facilitate operation, improve the aesthetics and standardized management of the welding workplace, and make it easier to move the tools required for welding operations along with the welding platform 1. Using the welding device provided in this embodiment, the chute hole 13 is arranged along the length of the welding platform 1 in the middle of the welding platform 1. A storage plate 14 is provided on the reinforcing rod 12, and a collection box 15 is provided on the storage plate 14, located directly below the chute hole 13. By using the collection box 15 located below the welding platform 1, commonly used parts for processing mining machinery equipment, or tools required during welding operations, can be placed in the collection box 15 in advance, facilitating operation during welding and thus improving the overall practicality of the welding device.

[0031] The welding device described in this utility model employs a bidirectional lead screw structure, where both the first bidirectional lead screw 41 and the second bidirectional lead screw 51 are bidirectional lead screws. A bidirectional lead screw consists of two sections of threads with opposite directions (one right-handed and one left-handed) machined onto a single lead screw. Two internal threaded moving blocks 42 are screwed onto the first bidirectional lead screw 41. Under the action of the manual turntable 43, the lead screw can achieve bidirectional linear motion by rotation. During forward motion (the right-handed thread is the active component), when the lead screw rotates to the right, the right-hand internal threaded moving block 42 moves along the thread direction, driving the connected fixed component to move to the right, thus achieving forward linear motion. When the movement is reversed (left-hand thread is active), when the screw rotates to the left, the internal thread moving block 42 on the left moves along the thread direction, driving the fixed component connected to it to move to the left, thus achieving reverse linear movement. The bidirectional screw structure has the advantage of enabling bidirectional switching control. By changing the rotation direction of the screw, the direction of movement can be flexibly controlled, and forward and reverse switching can be achieved without changing the equipment. Finally, the electric push rod 44 drives the pressure plate 45 to move, and the pressure plate 45 can be used to fix the workpiece to be welded.

[0032] Similarly, two internally threaded sliders 52 are screwed onto the second bidirectional lead screw 51. Under the action of the second manual turntable 55, the second bidirectional lead screw 51 drives the clamping plate 54 to move, and the pressure plate 45 can be used to clamp and fix the workpiece to be welded. Through the pressure plate 45 and the clamping plate 54, the workpiece to be welded is fixed from four directions: front, back, left, and right, which can prevent it from slipping during the welding process.

[0033] Furthermore, the hydraulic telescopic rod 31 used in the telescopic mechanism 3 and the electric push rod 44 used in the fixing component of the welding device described in this utility model are both commonly used power equipment in the prior art. The purpose of applying them to the welding device described in this utility model is to facilitate operation and control. Therefore, their specific models are not described in detail. The hydraulic telescopic rod 31 and the electric push rod 44 can both be small equipment available on the market to meet the usage requirements.

[0034] Therefore, the welding device described in this utility model has a telescopic mechanism 3 on the welding platform 1, a pressing mechanism 4 in the telescopic mechanism 3, and a clamping mechanism 5 in the sliding groove hole 13 on the top surface of the welding platform 1. By cooperating with the pressing mechanism 4 and the clamping mechanism 5, the workpiece to be welded on the welding platform 1 can be clamped and fixed to prevent it from sliding, thereby making the mechanical equipment more stable and facilitating the welding operation.

[0035] In summary, the welding device described in this utility model, by utilizing the cooperation of the clamping mechanism 4 and the holding mechanism 5, can effectively prevent the workpiece to be welded from sliding or shaking during the welding process, thereby improving its welding efficiency and welding quality, increasing the safety during welding, and its overall structure is simple, easy to operate, and suitable for widespread application.
