Description

Technical Field

[0001] This utility model relates to the field of engine repair and welding technology, specifically a welding machine for recycling used engines. Background Technology

[0002] The engine block is made of cast iron or alloy. When the engine is recycled, the damaged engine block can be repaired by welding. That is, for damage to non-critical parts, welding can be used to repair them. Before welding, the cracked area needs to be thoroughly cleaned to remove oil and impurities. Then, appropriate welding materials are used to fill the crack. After welding, the welded area needs to be ground and polished to ensure a smooth surface.

[0003] The welding process requires fixing the cylinder block. Currently, the engine is placed on the ground and the cylinder block is secured using shims. This method is extremely inconvenient. Due to the irregular shape of the cylinder block, if corners or edges are damaged, securing it with shims is difficult to achieve effective fixation. Therefore, we propose a welding machine for recycling used engines. Utility Model Content

[0021] The technical solution of this utility model will be clearly and completely described below with reference to its embodiments. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0022] Reference Figures 1 to 4 This utility model provides a technical solution: a welding machine for recycling waste engines, including a lifting frame and a welding power source 10, wherein the lifting frame is mounted on top of the mounting base 13. Figure 1 and Figure 2 As shown, the lifting frame includes a U-shaped frame 5 with its opening facing downwards. Specifically, the bottom of the U-shaped frame 5 is connected to the mounting base 13. An adjusting screw 6 is provided inside the U-shaped frame 5. The top of the adjusting screw 6 is rotatably connected to the U-shaped frame 5, and its bottom is rotatably connected to the mounting base 13. A rotating handle is provided on the top of the adjusting screw 6. Support rails 18 are provided on both sides of the U-shaped frame 5, and a support arm 3 is mounted on each support rail 18 via a slider.

[0023] like Figure 1 and Figure 2 As shown, the mounting base 13 has two symmetrical and horizontally positioned support legs 1 on one side, as... Figure 2 As shown, one end of the support arm 3 extends horizontally outward to the top of the support leg 1. Brake casters are provided at both ends of the bottom of the mounting base 13 and at the bottom of the end of the support leg 1. The mounting base 13 and the two support legs 1 form a U-shaped frame, which can move by the brake casters during use.

[0024] Furthermore, the support platform 4 is mounted on the lifting frame, allowing the support platform 4 to rise and fall along with the lifting frame. Specifically, the two support arms 3 are connected to the support platform 4 respectively, and the support platform 4 is connected to the screw nut located on the adjusting screw 6 (e.g., Figure 1 (As indicated by the middle arrow A) is connected, when you hold the rotating handle and rotate the adjusting screw 6, the adjusting screw 6 can drive the bearing platform 4 to rise and fall to the preset height.

[0025] Immediately afterwards, such as Figure 2 As shown, a first support 14 is provided on the top of the support platform 4, and a spline sleeve 15 is rotatably installed inside the first support 14. A drive shaft 16 perpendicular to one end of the spline sleeve 15 is also provided on the top of the support platform 4. Bevel gears 20 meshing with each other are provided on the ends of the drive shaft 16 and the spline sleeve 15 respectively. The drive shaft 16 is rotatably installed in a second support 21, which is fixed to the support platform 4. A rotating handle is also installed on the end of the drive shaft 16 away from the bevel gears 20. One end of the rotating handle is located outside the support platform 4, which can avoid contact with the support arm 3 when rotating the rotating handle. Rotating the rotating handle can drive the drive shaft 16 to rotate, and the drive shaft 16 can drive the spline sleeve 15 to rotate. In actual use, the diameter of the bevel gear 20 at the end of the drive shaft 16 is smaller than the diameter of the bevel gear 20 at the end of the spline sleeve 15. This can form a small gear driving a large gear to rotate, making it easier to rotate the drive shaft 16.

[0026] This application also includes a spline shaft 7 that matches the spline sleeve 15. In use, the spline shaft 7 can be freely inserted into the spline sleeve 15. One end of the spline shaft 7 is provided with a frame connected to the engine. The frame includes a mounting plate 8 coaxially disposed at the end of the spline shaft 7. Multiple strip supports 9 are rotatably mounted on the edge of the mounting plate 8. Each strip support 9 is provided with a strip groove 19. Each strip groove 19 is provided with a bolt connected to the engine. It should be noted that each engine has a flange near the output shaft. This flange is used to connect to the gearbox. However, the size of each engine is different, which causes the position of the holes on the flange edge to be different. Therefore, when fixing the engine, pull the splined shaft 7 out of the splined sleeve 15, then rotate the strip support 9 and slide the bolts at the same time to align each bolt with the hole on the flange. Then tighten the bolts. After the engine is detachably mounted on the frame, lift the engine and align the splined shaft 7 with the splined sleeve 15 and place it inside the splined sleeve 15. At this time, the engine can be fixed on the splined sleeve 15 and will not fall off. The operation is simple and convenient.

[0027] Since the spline shaft 7 can only move along the axial direction of the spline sleeve 15, the horizontally placed spline shaft 7 and spline sleeve 15 can stably support the engine. At this time, the engine can be disassembled, repaired or welded. Since the welding position of the engine is random and the engine needs to be adjusted to a suitable position during welding, the operator can hold the rotating handle to rotate the drive shaft 16, so that the drive shaft 16 drives the spline sleeve 15 to rotate. Therefore, the spline sleeve 15 will drive the engine to rotate.

[0028] To facilitate the positioning of the spline sleeve 15 and the engine, such as Figure 3As shown, a positioning mechanism for fixing the spline sleeve 15 is also provided on the top of the first support 14. The positioning mechanism is a T-shaped seat 17 set on the top of the first support 14. One end of the T-shaped seat 17 is located above the spline sleeve 15. A positioning bolt 22 is provided on the internal thread of the end of the T-shaped seat 17. When the engine is adjusted to the right angle, the positioning bolt 22 can be screwed to abut against the spline sleeve 15. At this time, the engine can be fixed and can rotate at any angle.

[0029] At this point, the welding power supply 10 can be turned on, and the operator can then use the welding torch to weld the damaged area of ​​the engine.

[0030] Furthermore, this application also improves the installation method of the welding power source 10, that is, a placement groove 12 is provided on the top of the mounting base 13, the welding power source 10 is placed in the placement groove 12, and through holes 23 are provided on both sides of the middle of the placement groove 12. A magic strap 11 is installed in one through hole 23, and the magic strap 11 passes through the other through hole 23 from the free end and tightens the welding power source 10.

[0031] Storage boxes 2 are also provided at both ends of the mounting base 13. In actual use, the welding power supply 10 needs to be powered on, and during welding, a cable needs to be installed on the power interface of the welding power supply 10. The end of the cable needs to be connected to the engine so that a welding arc can be generated. However, when not in use, the cable on the power interface and the power cord are stored in the storage box 2 to avoid the cables from becoming tangled.

[0032] Based on the above embodiments, it should be further noted that the diameter of the bolt head located in the slot 19 needs to be greater than the width of the slot to prevent the bolt head from falling out of the slot 19 when tightening the engine.

[0033] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
