Description

Technical Field

[0001] This utility model belongs to the field of automotive technology, and more specifically, it relates to a workbench for assembling engines and generators. Background Technology

[0002] The range extender is the core component of a range-extended vehicle, consisting of an engine and a generator, providing energy for the vehicle's operation. The engine and generator are connected by a torsional damper, which effectively absorbs torsional vibrations transmitted from the engine, improving the smoothness of power transmission. However, if the engine and generator are not aligned properly during assembly, the torsional damper will experience radial loads, leading to unstable power output and abnormal noises. Currently, engine and generator assembly sometimes involves a lifting method. This involves first fixing the engine to a support platform, then using a lifting device to hoist the generator, aligning the generator's splines with the spline holes of the torque damper at the rear of the engine, and then slightly shaking it before centering it. This lifting method is not only inefficient but also relies on manual shaking during assembly, compromising quality. Currently, there is a lack of an efficient assembly workbench for engine and generator assembly to improve assembly efficiency and quality. Summary of the Invention

[0003] The purpose of this invention is to provide a workbench for assembling engines and generators, in order to solve the problem of the lack of an efficient assembly workbench for assembling engines and generators, thereby improving the assembly efficiency and quality of engines and generators.

[0004] This utility model is achieved using the following technical solution: a workbench for assembling engines and generators, comprising a platform, an engine mounting plate detachably mounted on one side of the top surface of the platform, and multiple engine support rods mounted on the engine mounting plate; two side slide rails are provided on the other side of the top surface of the platform, and a generator mounting plate is slidably mounted on the side slide rails, with a slider installed between the generator mounting plate and the slide rails; multiple generator support rods are mounted on the top surface of the generator mounting plate, and plugs are detachably mounted on the rear ends of the side slide rails; a vertical plate is mounted on the top surface of the platform near the generator mounting plate, and a threaded hole is opened on the vertical plate, with a lead screw mounted on the threaded hole.

[0005] Furthermore, T-shaped grooves are respectively provided on the slide rails on both sides, and the sliders on both sides are T-shaped and inserted into the grooves of the corresponding slide rails. The tops of the sliders on both sides are respectively fixedly connected to the generator fixing plates.

[0006] Furthermore, the plugs on both sides are connected to the slide rail on the same side by bolts.

[0007] Furthermore, the engine mounting plate has multiple upper fixing holes along its edge, and the top surface of the platform has multiple second fixing holes corresponding to the first fixing holes. The first fixing holes and the second fixing holes are connected by a first bolt, and a nut is installed on one end of the first bolt.

[0008] Furthermore, multiple clamping plates are installed between the engine mounting plate and the platform. The clamping plates are U-shaped, and both the engine mounting plate and the platform are contained within the clamping plates. The clamping plates are fixedly connected to the engine mounting plate and the platform by a first bolt.

[0009] Furthermore, a stop bar is installed on the side of the engine mounting plate near the generator mounting plate on the platform. The stop bar is rotatably mounted on the platform via a rotating shaft. An upright plate is installed on the side of the platform near the engine mounting plate on the rotating shaft.

[0010] Furthermore, the engine mounting plate is also equipped with multiple wiring harness constraint plates, which are L-shaped.

[0011] Furthermore, a rocker wheel is installed at the rear end of the lead screw; a push plate is installed at the front end of the lead screw.

[0012] Furthermore, the bottom of the platform is equipped with multiple support legs, and the bottom of each support leg has a threaded hole. An adjusting screw is threaded into the threaded hole, and a base is installed at the bottom of the adjusting screw.

[0013] Furthermore, a drawer is installed at the bottom of the platform.

[0014] Compared with the prior art, the beneficial effects of this utility model are: The platform described in this invention can simultaneously position and support the engine and generator. The generator and engine are assembled using a generator mounting plate that slides relative to the platform. The engine support rod on the engine mounting plate corresponds to the positioning support position on the engine. Once the engine is placed on the engine support rod on the engine mounting plate, its position is determined. Similarly, the generator support rod on the generator mounting plate corresponds to the positioning support position on the generator. Once the generator is placed on the generator support rod on the generator mounting plate, its position is determined. This ensures assembly quality during the engine and generator assembly process and eliminates the need for multiple alignment checks using lifting tools, effectively improving assembly efficiency.

Detailed Implementation

[0017] To enable those skilled in the art to better understand the technical solutions of this utility model, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort should fall within the scope of protection of this utility model.

[0018] A workbench for assembling engines and generators includes a platform 1. Multiple legs 18 are mounted on the bottom of the platform 1, with four legs 18 supporting the platform 1. Each leg 18 has a threaded hole at its bottom, through which an adjusting screw is threadedly connected. A base 19 is mounted on the bottom of the adjusting screw. By providing a base 19 with an adjusting screw, the height of the platform 1 can be easily adjusted, making the invention suitable for different ground heights.

[0019] An engine mounting plate 2 is detachably installed on one side of the top surface of the platform 1. By designing the engine mounting plate 2 and the platform 1 as detachable structures, this utility model allows for easy replacement of different types of engine mounting plates 2 on the platform 1, with different engine mounting plates 2 corresponding to different engines.

[0020] The engine mounting plate 2 has multiple upper fixing holes along its edge, and the top surface of the platform 1 has multiple second fixing holes corresponding to the first fixing holes. The first fixing holes and the second fixing holes are connected by a first bolt 11, and a nut is installed on one end of the first bolt 11. This utility model achieves relative fixation between the engine mounting plate 2 and the platform 1 through bolts and nuts.

[0021] Multiple U-shaped clamping plates 12 are installed between the engine mounting plate 2 and the platform 1. Both the engine mounting plate 2 and the platform 1 are contained within the clamping plates 12, and the clamping plates 12 are fixedly connected to the engine mounting plate 2 and the platform 1 by first bolts 11. This invention, by setting the U-shaped clamping plates 12, can further enhance the fixing stability of the engine mounting plate 2 and the platform 1, with both the engine mounting plate 2 and the platform 1 inserted into the clamping plates 12.

[0022] Multiple engine support rods 3 are installed on the engine mounting plate 2. The engine support rods 3 on the engine mounting plate 2 correspond to the positioning support positions on the engine. When the engine is placed on the engine support rods 3 on the engine mounting plate 2, the position of the engine is determined.

[0023] The top surface of the platform 1 is provided with two side slide rails 4 on one side of the engine mounting plate 2. The generator mounting plate 5 is slidably installed on the two side slide rails 4. The slider 6 is installed between the generator mounting plate 5 and the slide rail 4. The two side slide rails 4 are respectively provided with T-shaped grooves. The two side sliders 6 are both T-shaped and inserted into the grooves of the corresponding slide rails 4. The top of the two side sliders 6 is respectively fixedly connected to the generator mounting plate 5.

[0024] Each of the two side slide rails 4 has a detachable plug 8 installed at its rear end; the plugs 8 on both sides are connected to the slide rail 4 on the same side by bolts. By setting the plugs 8 on both sides, this utility model can limit the sliding of the generator fixing plate 5 to prevent the generator fixing plate 5 from sliding backward off the two side slide rails 4.

[0025] Multiple generator support rods 7 are installed on the top surface of the generator mounting plate 5. The generator support rods 7 on the generator mounting plate 5 correspond to the positioning support positions on the generator. When the generator is placed on the generator support rods 7 on the generator mounting plate 5, the position of the generator is determined.

[0026] A vertical plate 9 is installed on the top surface of the platform 1 at one end near the generator mounting plate 5. A threaded hole is provided on the vertical plate 9, and a lead screw 10 is installed in the threaded hole. By rotating the lead screw 10, the lead screw 10 can move back and forth relative to the vertical plate 9. During the forward movement of the lead screw 10, it can contact the generator mounting plate 5 and push the generator mounting plate 5 forward. By setting the lead screw 10, the movement of the generator towards the engine can be more easily controlled, making the assembly of the generator and engine more convenient.

[0027] The rear end of the lead screw 10 is equipped with a rocker wheel 16. By setting the rocker wheel 16, the lead screw 10 can be rotated more easily. The front end of the lead screw 10 is equipped with a push plate 17. By setting the push plate 17, the contact area between the lead screw 10 and the generator fixing plate 5 can be increased.

[0028] The platform 1 has a stop bar 13 installed on the side of the engine mounting plate 2 near the generator mounting plate 5. The stop bar 13 can be designed as a V-shaped structure and is rotatably mounted on the platform 1 via a pivot. A vertical plate 14 is installed on the side of the platform 1 near the engine mounting plate 2 via the pivot. This invention, by setting the stop bar 13, can limit the forward movement of the generator mounting plate 5. When the generator is installed on the generator support rod 7 on the generator mounting plate 5 and assembly is not required temporarily, the stop bar 13 can be rotated around the pivot axis towards the generator mounting plate 5, and the stop bar 13 rests on the vertical plate 14. At this time, the stop bar 13 is in front of the engine mounting plate 2 and its height is higher than the bottom surface of the generator mounting plate 5, preventing the generator mounting plate 5 from moving forward. When assembly of the generator and engine is required, the stop bar 13 needs to be rotated outward around the pivot axis, that is, rotated away from the generator mounting plate 5. At this time, the height of the stop bar 13 is less than the height of the bottom surface of the generator mounting plate 5, and the stop bar 13 will not prevent the generator mounting plate 5 from moving forward.

[0029] The engine mounting plate 2 is also equipped with multiple wire harness constraint plates 15, which are L-shaped. This invention, by setting the wire harness constraint plates 15, can constrain the engine's wire harness, preventing it from bumping or colliding. The L-shaped wire harness constraint plates 15 and the platform 1 form a wire harness constraint space; when constraining the wire harness, it is only necessary to insert the wire harness into the constraint space.

[0030] A drawer 20 is installed at the bottom of the tabletop 1. By providing the drawer 20, this utility model can have storage capacity.

[0031] The working process of this utility model is as follows: First, the engine is placed on the engine support rod 3 on the engine mounting plate 2, and the generator is placed on the generator support rod 7 on the generator mounting plate 5. When assembly is required, the rocker wheel 16 at the rear end of the lead screw 10 can be rotated. The rocker wheel 16 drives the lead screw 10 to rotate and move forward. During the forward movement, the lead screw 10 will contact the generator mounting plate 5 and drive the generator mounting plate 5 to move towards the engine mounting plate 2, thereby gradually bringing the generator and the engine into contact.
