Description

Technical Field

[0001] The invention belongs to the technical field of engine assembly equipment, and particularly relates to a manual disassembly and assembly tool vehicle for an engine range extender. Background Art

[0002] In the production, manufacturing, maintenance, and servicing of engine range extenders, their assembly processes face numerous challenges. On the one hand, the motor rotor adopts a permanent magnetic structure and is installed at the rear end of the engine crankshaft. During the co-assembly process of the motor rotor and the stator, a large magnetic torsion moment is generated between them, which greatly increases the co-assembly difficulty and requires extremely high precision for the assembly process and tools. On the other hand, in the assembly and subsequent maintenance operations of the range extender, traditional simple disassembly and assembly tools are no longer able to meet the increasingly demanding assembly technical standards. These simple tools are extremely likely to scratch the copper wires in the stator coil during operation, not only affecting product quality but also resulting in low manual assembly efficiency, complex and cumbersome operation processes, and high safety risks, seriously limiting the assembly precision of the range extender and the quality of the final product. Summary of the Invention

[0003] To solve the problems in the background art, the invention provides a manual disassembly and assembly tool vehicle for an engine range extender.

[0004] To achieve the above object, the invention adopts the following technical solutions: A manual disassembly and assembly tool vehicle for an engine range extender includes a vehicle frame, an adjustment mechanism, a moving platform, a generator mounting plate I, a nut bracket, an engine mounting plate II, an engine pressing plate mechanism, a lead screw transmission mechanism, two universal braking wheels, two fixed wheels, two linear slide rail assemblies, a plurality of support rods I, and a plurality of support rods II;

[0005] The lower end of the vehicle frame is provided with universal braking wheels and fixed wheels. On one side of the upper end of the vehicle frame, there are two linear slide rail assemblies, and both of the two linear slide rail assemblies are connected to the lower end of the moving platform. On one side of the upper end of the moving platform, there is an adjustment mechanism. On the other side of the upper end of the moving platform, there is a vertically arranged generator mounting plate I. Horizontally arranged on the generator mounting plate I are a plurality of support rods I. The lower end of the moving platform is connected to the lead screw transmission mechanism through a nut bracket. The lead screw transmission mechanism is fixedly connected to the upper end of the vehicle frame and is arranged between the two linear slide rail assemblies. On the other side of the upper end of the vehicle frame, there is an engine mounting plate II. Horizontally arranged on the engine mounting plate II are a plurality of support rods II. The engine mounting plate II is used in cooperation with a plurality of engine pressing plate mechanisms, and the plurality of engine pressing plate mechanisms are all fixed on the vehicle frame.

[0006] The lead screw transmission mechanism includes a trapezoidal lead screw, a lead screw nut, a handwheel, a semi-circular key, a bolt I, a gasket, and two bearing seats;

[0007] The two ends of the trapezoidal lead screw are respectively rotatably connected to the corresponding bearing seats, and the two bearing seats are both fixedly connected to the vehicle frame. The lead screw nut is threadedly connected to the trapezoidal lead screw and is arranged between the two bearing seats. The lead screw nut is fixedly connected to the nut bracket. The trapezoidal lead screw and the handwheel are inserted and limited by a semi-circular key and fixedly connected by a bolt 1, and a gasket is sleeved on the bolt 1.

[0008] The adjustment mechanism includes a push rod and a base;

[0009] The base is fixedly connected to the upper end of the moving platform and is arranged corresponding to the generator mounting plate 1. The base is provided with threaded holes, the outer wall of the push rod is provided with external threads, and the push rod is threadedly connected to the threaded holes.

[0010] Each engine pressing plate mechanism includes an internally threaded tube, a pressing plate and a bolt 2;

[0011] The internally threaded tube is arranged vertically and fixedly connected to the vehicle frame. The pressing plate is provided with a long hole along the length direction. The bolt 2 rotatably passes through the long hole and is threadedly connected to the internally threaded tube.

[0012] Compared with the prior art, the beneficial effects of the present invention are:

[0013] 1. Precise positioning and support: The engine is placed on the engine mounting plate 2, and multiple support rods 2 are docked with the engine cylinder block support holes, providing preliminary and precise positioning and support for the engine, which helps the smooth progress of subsequent disassembly and assembly operations.

[0014] 2. Firm and reliable fixation: Multiple engine pressing plate mechanisms are used to fix the engine. By adjusting the position of the pressing plate on the long hole and tightening with bolt 2, firm fixation of the engine can be achieved, avoiding the engine from shaking or shifting during the disassembly and assembly process, and ensuring operation safety.

[0015] 3. Flexible position adjustment: The position of the moving platform can be flexibly adjusted through the lead screw transmission mechanism. Rotate the handwheel to make the trapezoidal lead screw rotate, and then drive the lead screw nut to move horizontally. The lead screw nut is connected to the moving platform through the nut bracket, thereby driving the moving platform to move along the linear slide rail assembly and approach the engine, facilitating subsequent docking operations.

[0016] 4. Precise and efficient docking: When the moving platform approaches the engine, multiple support rods 1 on the generator mounting plate 1 at its upper end are precisely docked with the engine rotor, restricting the magnetic torsion moment between the stator and the rotor, ensuring an appropriate clearance between the stator and the rotor during installation, ensuring the normal operation of the engine range extender, and improving the disassembly and assembly accuracy.

[0017] 5. Convenient height fine-tuning: The height of the generator can be fine-tuned through the adjustment mechanism. Rotate the ejector rod, and use the threaded connection between its external thread and the threaded hole of the base to achieve lifting. The operation is simple and can better meet the height requirements during the disassembly and assembly of the engine range extender.

[0018] In summary, through a series of precise mechanism and component designs, this manual disassembly and assembly tool vehicle for the engine range extender realizes the rapid, accurate disassembly, assembly, and fixation of the engine, greatly improving the work efficiency and disassembly and assembly accuracy.

[0024] Next, the technical solutions in the present invention will be clearly and completely described in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0025] This embodiment describes a manual disassembly and assembly tool vehicle for an engine range extender, including a vehicle frame 1, an adjustment mechanism 5, a moving platform 4, a generator mounting plate 6, a nut bracket 8, an engine mounting plate 9, an engine pressing plate mechanism 10, a lead screw drive mechanism 11, two universal braking wheels 2, two fixed wheels 3, two linear slide rail assemblies 7, a plurality of support rods 24 and a plurality of support rods 25;

[0026] The lower end of the frame 1 is provided with two universal braking wheels 2 and two fixed wheels 3. One side of the upper end of the frame 1 is provided with two linear slide rail assemblies 7. Both of the two linear slide rail assemblies 7 are connected to the lower end of the moving platform 4. One side of the upper end of the moving platform 4 is provided with an adjustment mechanism 5. The other side of the upper end of the moving platform 4 is provided with a vertically arranged first generator mounting plate 6. A plurality of first support rods 24 are horizontally arranged on the first generator mounting plate 6. The lower end of the moving platform 4 is connected to a lead screw transmission mechanism 11 through a nut bracket 8. The lead screw transmission mechanism 11 is fixedly connected to the upper end of the frame 1 and is arranged between the two linear slide rail assemblies 7. The other side of the upper end of the frame 1 is provided with a second engine mounting plate 9. A plurality of second support rods 25 are arranged on the second engine mounting plate 9. The second engine mounting plate 9 is used in cooperation with a plurality of engine pressing plate mechanisms 10. All of the plurality of engine pressing plate mechanisms 10 are fixed on the frame 1.

[0027] The lead screw transmission mechanism 11 includes a trapezoidal lead screw 12, a lead screw nut 13, a hand wheel 15, a half-round key 16, a first bolt 17, a gasket 18 and two bearing seats 14;

[0028] Both ends of the trapezoidal lead screw 12 are respectively rotatably connected to the corresponding bearing seats 14. Both of the two bearing seats 14 are fixedly connected to the frame 1. The lead screw nut 13 is threadedly connected to the trapezoidal lead screw 12 and is arranged between the two bearing seats 14. The lead screw nut 13 is fixedly connected to the nut bracket 8. The trapezoidal lead screw 12 and the hand wheel 15 are inserted and limited through the half-round key 16 and are fixedly connected through the first bolt 17. The gasket 18 is sleeved on the first bolt 17.

[0029] The adjustment mechanism 5 includes a push rod 19 and a base 20;

[0030] The base 20 is fixedly connected to the upper end of the moving platform 4 and is correspondingly arranged with the first generator mounting plate 6. The base 20 is provided with a threaded hole. The outer wall of the push rod 19 is provided with an external thread. The push rod 19 is threadedly connected to the threaded hole.

[0031] Each of the engine pressing plate mechanisms 10 includes an internally threaded tube 21, a pressing plate 22 and a second bolt 23; The internally threaded tube 21 is vertically arranged and is fixedly connected to the frame 1. The pressing plate 22 is provided with a long hole along the length direction. The second bolt 23 rotatably passes through the long hole and is threadedly connected to the internally threaded tube 21.

[0032] When using the present invention, first, place the engine on the second engine mounting plate 9. At this time, a plurality of second support rods 25 are butted against the cylinder block support holes of the engine, providing a preliminary positioning and support for the engine;

[0033] Next, use multiple engine pressing plate mechanisms 10 to fix the engine. The inner threaded pipe 21 is vertically arranged and fixedly connected to the vehicle frame 1. The pressing plate 22 is matched with the second bolt 23 through the long hole provided along its length direction. The second bolt 23 rotates through the long hole and is threadedly connected to the inner threaded pipe 21. By adjusting the position of the pressing plate 22 on the long hole and using the second bolt 23 for fastening, the firm fixation of the engine can be achieved.

[0034] Then, adjust the position of the moving platform 4 through the lead screw transmission mechanism 11. Rotate the handwheel 15 to make the trapezoidal lead screw 12 rotate. Since the lead screw nut 13 is threadedly connected to the trapezoidal lead screw 12, the lead screw nut 13 will move horizontally. The lead screw nut 13 is connected to the moving platform 4 through the nut bracket 8, so it can drive the moving platform 4 to move along the linear slide rail assembly 7 and approach the engine.

[0035] During the process of the moving platform 4 approaching the engine, multiple support rods 24 on the generator mounting plate 6 vertically arranged at its upper end will be docked with the rotor of the engine. The main function of these support rods 24 is to limit the magnetic torsional moment between the stator and the rotor, ensuring that an appropriate fitting clearance can be maintained when the stator and the rotor are installed, thereby ensuring the normal operation of the engine range extender.

[0036] Finally, finely adjust the height of the generator through the adjustment mechanism 5. By rotating the ejector rod 19, since its outer wall is provided with external threads and is threadedly connected to the threaded hole on the base 20, the lifting of the ejector rod 19 can be achieved, thereby finely adjusting the height of the generator.

[0037] In summary, through a series of precise mechanism and component designs, this manual disassembly and assembly tool vehicle for the engine range extender realizes the rapid, accurate disassembly, assembly, and fixation of the engine, greatly improving the work efficiency and disassembly and assembly accuracy.
