Description

Technical Field

[0001] This invention relates to the field of diesel engine processing technology, specifically to a tooling and method for installing a flywheel housing of a marine high-speed diesel engine. Background Technology

[0002] The flywheel housing, typically installed between the engine and transmission, connects to the crankcase externally and houses the flywheel assembly, starter, oil pan, etc. It usually features a cooling vent and a heat dissipation cover. Structurally, it is simple and easy to install. The flywheel housing is a crucial basic component of the engine, connecting the engine and transmission, bearing part of their weight, protecting the clutch and flywheel, and serving as a support component. Its manufacturing quality directly affects engine performance.

[0003] The diesel generator set needs to meet the dual starting mode, so the flywheel housing of the diesel engine needs to be replaced from a single-ear flywheel housing to a double-ear flywheel housing. However, the flywheel housing could not be installed during the installation process due to space limitations. Summary of the Invention

[0004] The purpose of this invention is to provide a tooling for installing a flywheel housing of a marine high-speed diesel engine, so as to solve the problems mentioned in the background art.

[0005] To solve the above-mentioned technical problems, the present invention is achieved through the following technical solution:

[0006] This invention relates to a flying wheel housing installation fixture for a marine high-speed diesel engine, comprising a lifting self-locking mechanism, wherein a self-centering clamping mechanism and a steering mechanism are installed on the outer wall of the lifting self-locking mechanism;

[0007] The steering mechanism includes a support plate, a fixed plate connected to the outer wall of the support plate, an upper suspension slide rail connected to the outer wall of the fixed plate, a strip slider slidably connected to the outer wall of the upper suspension slide rail, a lifting member overlapping the outer wall of the strip slider, a connecting member connected to the outer wall of the support plate, a drive cylinder movably connected to the outer wall of the connecting member, a self-locking member connected to the output shaft of the drive cylinder, a self-locking base movably connected to the outer wall of the self-locking member, the outer wall of the self-locking base being connected to the outer wall of the support plate, and the outer wall of the self-locking member being slidably connected to the inner wall of the strip slider.

[0008] By adopting the above technical solution, the flywheel housing lifting and self-locking effect is achieved. When the drive cylinder is activated, the output shaft of the drive cylinder drives the self-locking component to move, which in turn drives the strip slider to move upward along the upper suspension rail, thereby driving the lifting component to move upward and lifting the placement plate. At this time, the self-locking component and the strip slider form an angle of 10 degrees. Due to the gravity of the flywheel housing, the placement plate is pressed downward, which in turn presses the strip slider downward and locks the self-locking component, thus achieving the self-locking effect.

[0009] Furthermore, the inner wall of the lifting member is connected to a placement plate, the outer wall of the placement plate is connected to a telescopic cylinder, the output shaft of the telescopic cylinder is connected to a planar slider, the inner wall of the placement plate is connected to a planar groove, and the outer wall of the planar slider is slidably connected to the inner wall of the planar groove.

[0010] By adopting the above technical solution, the effect of planar slider movement is achieved, and the output shaft of the telescopic cylinder drives the planar slider to slide along the inner wall of the planar groove.

[0011] Furthermore, the inner wall of the placement plate is connected to a vertical slide rail, the inner wall of the vertical slide rail is slidably connected to a curved slider, the outer wall of the curved slider is slidably connected to the outer wall of the flat slider, the inner wall of the placement plate is rotatably connected to a movable rod, the inner wall of the movable rod is rotatably connected to a drive roller, and the outer wall of the drive roller is rotatably connected to the outer wall of the curved slider.

[0012] By adopting the above technical solution, the effect of the movable rods retracting inward is achieved. Since the outer wall of the curved slider has a certain slope, the flat slider will lift the curved slider when it moves. When the curved slider moves upward, it will drive the drive roller to rotate. Due to the action of the telescopic spring, the two movable rods will retract inward.

[0013] Furthermore, a clamping roller is rotatably connected to the inner wall of the movable rod, and a telescopic spring is connected between the two movable rods.

[0014] By adopting the above technical solution, the self-centering clamping effect is achieved. The curved slider and the two clamping rollers retract inward to clamp, thereby achieving the effect of clamping flywheel housings of different sizes.

[0015] Furthermore, a toothed plate is slidably connected to the inner wall of the support plate, and a mating gear is rotatably connected to the outer wall of the support plate. The teeth of the mating gear mesh with the teeth of the toothed plate. A driving link is connected to the outer wall of the toothed plate, and a driven link is rotatably connected to the outer wall of the driving link. One end of the driven link is connected to a movable roller.

[0016] By adopting the above technical solution, the effect of steering the moving roller is achieved. When the pull rod is rotated, the pull rod will drive the mating gear to rotate. Since the teeth of the mating gear mesh with the teeth of the tooth plate, the tooth plate will move left and right. When the tooth plate moves, it will drive the drive linkage to move, thereby driving the driven linkage to move, and then driving the moving roller to rotate.

[0017] Furthermore, a balance link is rotatably connected between the two mating gears, and a tie rod is rotatably connected to the outer wall of one of the mating gears.

[0018] By adopting the above technical solution, the effect of synchronous steering of the moving rollers is achieved. Since there is a balance link between the two mating gears, the synchronous steering of the front and rear moving rollers is realized.

[0019] Based on the above technical solution, a method for installing a flywheel housing of a marine high-speed diesel engine is also proposed, comprising the following steps:

[0020] S1. Place the flywheel housing to be installed on the placement plate, open the telescopic cylinder, and the output shaft of the telescopic cylinder drives the flat slider to slide on the inner wall of the flat slide groove. Since the outer wall of the curved slider has a certain slope, the flat slider will lift the curved slider when it moves. When the curved slider moves upward, it will drive the drive roller to rotate. Due to the action of the telescopic spring, it will drive the two movable rods to retract inward, thereby driving the clamping roller to clamp the flywheel housing inward, achieving the effect of self-centering clamping, thus adapting to the clamping effect of flywheel housings of different sizes.

[0021] S2. When it is necessary to lift and install the flywheel housing, start the drive cylinder. The output shaft of the drive cylinder drives the self-locking component to move, which in turn drives the strip slider to move upward along the upper suspension rail, thereby driving the lifting component to move upward and lifting the placement plate. At this time, the self-locking component and the strip slider form an angle of 10 degrees. Due to the gravity of the flywheel housing, the placement plate is pressed downward, which in turn presses the strip slider downward and locks the self-locking component, thus achieving the self-locking effect.

[0022] S3. When the device needs to be turned, the pull rod is rotated, which drives the mating gear to rotate. Since the teeth of the mating gear mesh with the teeth of the tooth plate, the tooth plate will move left and right. When the tooth plate moves, it will drive the drive linkage to move, which in turn drives the driven linkage to move, and then drives the moving roller to rotate. Since the two mating gears are rotatably connected by a balance linkage, the front and rear moving rollers can be turned synchronously.

[0023] The present invention has the following beneficial effects:

[0024] (1) The present invention uses a self-centering clamping mechanism to start and drive the curved slider to move upward, thereby driving the movable rod to retract inward, achieving the clamping effect of clamping the roller and the curved slider inward, thus adapting to the installation of flywheel housings of different sizes, ensuring a good connection between the flywheel and the transmission device, thereby improving transmission efficiency and reducing energy loss.

[0025] (2) The present invention is provided with a lifting self-locking mechanism. By lifting and locking the flywheel housing, the flywheel housing can be correctly installed, reducing wear and damage to parts caused by improper installation, extending the service life of the mechanical equipment, and the flywheel housing can be more firmly fixed on the flywheel, reducing friction and loosening between parts, thereby reducing vibration and noise, and improving the stability and comfort of the mechanical equipment.

[0026] (3) The present invention is equipped with a steering mechanism, which realizes the steering of the moving roller by rotating the pull rod, thereby enabling better adaptation to the ground environment during the movement of the flywheel housing, reducing manpower consumption and improving installation efficiency.

[0027] Of course, any product implementing this invention does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

Detailed Implementation

[0038] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0039] Please see Figure 1 - Figure 7 As shown, the present invention is a tooling for installing a flywheel housing of a marine high-speed diesel engine, including a lifting self-locking mechanism 100, and a self-centering clamping mechanism 200 and a steering mechanism 300 installed on the outer wall of the lifting self-locking mechanism 100.

[0040] The steering mechanism 300 includes a support plate 301, a fixed plate 101 connected to the outer wall of the support plate 301, an upper suspension slide rail 103 connected to the outer wall of the fixed plate 101, a strip slider 104 slidably connected to the outer wall of the upper suspension slide rail 103, a lifting member 105 overlapping the outer wall of the strip slider 104, a connector 102 connected to the outer wall of the support plate 301, a drive cylinder 108 movably connected to the outer wall of the connector 102, a self-locking member 106 connected to the output shaft of the drive cylinder 108, a self-locking base 107 movably connected to the outer wall of the self-locking member 106, the outer wall of the self-locking base 107 connected to the outer wall of the support plate 301, and the outer wall of the self-locking member 106 slidably connected to the inner wall of the strip slider 104.

[0041] When the drive cylinder 108 is activated, its output shaft drives the self-locking component 106 to move, which in turn drives the strip slider 104 to move upward along the upper suspension rail 103, thereby driving the lifting component 105 to move upward and lifting the placement plate 201. At this time, the self-locking component 106 and the strip slider 104 form a 90-degree angle. Due to the gravity of the flywheel housing, the placement plate 201 is pressed downward, which in turn presses the strip slider 104 downward, locking the self-locking component 106 and achieving a self-locking effect.

[0042] The inner wall of the lifting component 105 is connected to a placement plate 201, the outer wall of the placement plate 201 is connected to a telescopic cylinder 202, the output shaft of the telescopic cylinder 202 is connected to a planar slider 203, the inner wall of the placement plate 201 is connected to a planar groove 204, and the outer wall of the planar slider 203 is slidably connected to the inner wall of the planar groove 204.

[0043] The output shaft of the telescopic cylinder 202 drives the planar slider 203 to slide along the inner wall of the planar groove 204.

[0044] The inner wall of the placement plate 201 is connected to a vertical slide rail 211, and the inner wall of the vertical slide rail 211 is slidably connected to a curved slider 205. The outer wall of the curved slider 205 is slidably connected to the outer wall of the flat slider 203. The inner wall of the placement plate 201 is rotatably connected to a movable rod 207, and the inner wall of the movable rod 207 is rotatably connected to a drive roller 209. The outer wall of the drive roller 209 is rotatably connected to the outer wall of the curved slider 205.

[0045] Because the outer wall of the curved slider 205 has a certain slope, the flat slider 203 will lift the curved slider 205 when it moves. When the curved slider 205 moves upward, it will drive the drive roller 209 to rotate. Due to the action of the telescopic spring 208, it will drive the two movable rods 207 to retract inward.

[0046] A clamping roller 210 is rotatably connected to the inner wall of the movable rod 207, and a telescopic spring 208 is connected between the two movable rods 207.

[0047] The curved slider 205 and the two clamping rollers 210 retract inward to clamp, thereby achieving the effect of clamping flywheel housings of different sizes.

[0048] A toothed plate 302 is slidably connected to the inner wall of the support plate 301, and a mating gear 303 is rotatably connected to the outer wall of the support plate 301. The teeth of the mating gear 303 mesh with the teeth of the toothed plate 302. A drive link 305 is connected to the outer wall of the toothed plate 302, and a driven link 306 is rotatably connected to the outer wall of the drive link 305. One end of the driven link 306 is connected to a moving roller 307.

[0049] Rotating the pull rod 308 will cause the mating gear 303 to rotate. Since the teeth of the mating gear 303 mesh with the teeth of the toothed plate 302, the toothed plate 302 will move left and right. When the toothed plate 302 moves, it will drive the drive link 305 to move, which will drive the driven link 306 to move, and then drive the moving roller 307 to rotate.

[0050] A balance rod 304 is rotatably connected between two mating gears 303, and a tie rod 308 is rotatably connected to the outer wall of one of the mating gears 303.

[0051] Because a balance link 304 is rotatably connected between the two mating gears 303, the synchronous steering of the front and rear moving rollers 307 is achieved.

[0052] A method for installing a flywheel housing of a marine high-speed diesel engine includes the following steps:

[0053] S1. Place the flywheel housing to be installed on the placement plate 201, open the telescopic cylinder 202, and the output shaft of the telescopic cylinder 202 drives the flat slider 203 to slide on the inner wall of the flat slide groove 204. Since the outer wall of the curved slider 205 has a certain slope, the flat slider 203 will lift the curved slider 205 when it moves. When the curved slider 205 moves upward, it will drive the drive roller 209 to rotate. Due to the action of the telescopic spring 208, it will drive the two movable rods 207 to retract inward, thereby driving the clamping roller 210 to clamp the flywheel housing inward, achieving the effect of self-centering clamping, thus adapting to the clamping effect of flywheel housings of different sizes.

[0054] S2. When it is necessary to lift and install the flywheel housing, start the drive cylinder 108. The output shaft of the drive cylinder 108 drives the self-locking component 106 to move, which in turn drives the strip slider 104 to move upward along the upper suspension rail 103, thereby driving the lifting component 105 to move upward, thus lifting the placement plate 201. At this time, the self-locking component 106 and the strip slider 104 form a 90-degree angle. Due to the gravity of the flywheel housing, the placement plate 201 is pressed downward, which in turn presses the strip slider 104 downward, locking the self-locking component 106 and achieving the self-locking effect.

[0055] S3. When the device needs to be turned, the pull rod 308 is rotated, which will drive the mating gear 303 to rotate. Since the teeth of the mating gear 303 mesh with the teeth of the toothed plate 302, the toothed plate 302 will move left and right. When the toothed plate 302 moves, it will drive the drive link 305 to move, which will drive the driven link 306 to move, and then drive the moving roller 307 to rotate. Since the two mating gears 303 are rotatably connected by the balance link 304, the synchronous turning of the front and rear moving rollers 307 is achieved.
