Description

Technical Field

[0001] This invention relates to the field of diesel engine spraying technology, and more particularly to an auxiliary installation structure for diesel engine spraying process. Background Technology

[0002] During the production of diesel engines, the installed diesel engines need to be painted to achieve effects such as waterproofing and anti-oxidation. Marine diesel engines are large in size and heavy and cannot be moved, making painting troublesome. The diesel engine painting process is the last step before inspection. In order to complete the painting of diesel engines, the existing technical means usually adopts hoisting for painting, but it is only suitable for small civilian diesel engines.

[0003] Lifting marine diesel engines can damage internal parts, and the process of lifting and painting marine diesel engines is highly dangerous. Some techniques involve painting on a workbench, and to ensure the painting effect, the diesel engine is moved to ensure the painting effect on the bottom of the diesel engine. However, the painting process of marine diesel engines requires 3-5 coats, and the movement of the diesel engine needs to be stable. Repeated lifting and moving can easily cause wear and tear on the internal parts of the diesel engine, and in severe cases, the diesel engine may be defective. Therefore, we propose an auxiliary installation structure for the diesel engine painting process. Summary of the Invention

[0004] The purpose of this invention is to reduce the impact of the above-mentioned situation and to provide an auxiliary installation structure for diesel engine spraying process.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: an auxiliary installation structure for diesel engine spraying process, including a workbench and multiple support seats provided on the workbench, wherein the workbench is provided with a transmission mechanism for horizontal sliding of the work plate and a lifting mechanism for lifting the limit rod;

[0006] The transmission mechanism includes a stepper motor, a rotating rod is provided at the drive end of the stepper motor, and a threaded sleeve for transmitting the work plate is provided on the rotating rod. The work plate is symmetrically provided with a release area for unloading the threaded sleeve. A connecting rod parallel to the rotating rod is provided inside the worktable. A first bevel gear and a second bevel gear are symmetrically provided on the connecting rod, and the second bevel gear is meshed with a bevel gear transmission component. The connecting rod and the rotating rod are connected through a transmission assembly.

[0007] The workbench is equipped with a spring assembly for resetting the work plate.

[0008] The lifting mechanism includes a vertically mounted threaded column on the working plate, a third bevel gear for connecting to the first bevel gear or a bevel gear transmission component at the bottom of the threaded column, a damper on the threaded column, a threaded push rod on the threaded column, and a sliding frame on the threaded push rod.

[0009] Preferably, the working plate has a threaded area that is threadedly connected to the working plate.

[0010] Preferably, the workbench is provided with a sliding plate for supporting the work plate, and the work plate is slidably connected to the sliding plate.

[0011] Preferably, the working plate is symmetrically provided with limit rods, and the bottom of the sliding frame is symmetrically provided with limit grooves that slide with the limit rods.

[0012] Preferably, the workbench is provided with a safety crossbar for limiting the upward position of the sliding frame.

[0013] Preferably, the workbench is provided with a sliding groove, and the sliding groove is slidably connected to the sliding frame.

[0014] Compared with the prior art, the beneficial effects of the present invention are:

[0015] 1. It is equipped with a workbench, which contains a transmission mechanism for transporting diesel engines and a lifting mechanism. After the transmission is completed, the diesel engine is lowered and touched up with paint. After resetting, it can be transported again to facilitate multiple relocations in conjunction with spraying, ensuring the safety of diesel engine transportation.

[0016] 2. This invention solves the problem of incomplete coating of large diesel engines (i.e., poor bottom coating effect) by small displacement, thereby improving the coating effect. At the same time, the structure is compact and easy to implement, solving the problem of mechanical wear or damage caused by multiple lifting operations. It ensures the safety of the diesel engine with a relatively stable movement method. In addition, the design of the lifting structure also facilitates the transportation work after coating.

[0023] 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.

[0024] Please see Figure 1-4 The present invention provides a technical solution: an auxiliary installation structure for diesel engine spraying process, including a workbench 1 and a plurality of support seats 12 provided on the workbench 1. The workbench 1 is provided with a transmission mechanism for horizontal sliding of the work plate 23 and a lifting mechanism for lifting the sliding frame 33.

[0025] The transmission mechanism includes a stepper motor 2, a rotating rod 21 is provided at the drive end of the stepper motor 2, and a threaded sleeve 22 for transmitting the working plate 23 is provided on the rotating rod 21. The working plate 23 is symmetrically provided with a release area 2302 for unloading the threaded sleeve 22. A connecting rod 24 parallel to the rotating rod 21 is provided in the worktable 1. A first bevel gear 2401 and a second bevel gear 2402 are symmetrically provided on the connecting rod 24, and the second bevel gear 2402 is meshed with a bevel gear transmission component 3102. The connecting rod 24 and the rotating rod 21 are connected through a transmission assembly 25.

[0026] The workbench 1 is equipped with a spring assembly 26 for resetting the work plate 23;

[0027] The lifting mechanism includes a vertically mounted threaded post 3 on the working plate 23. The bottom of the threaded post 3 is provided with a third bevel gear 3101 for connecting with the first bevel gear 2401 or the bevel gear transmission component 3102. A damper 35 is provided on the threaded post 3. A threaded push rod 32 is provided on the threaded post 3, and the bottom of the threaded push rod 32 is threadedly connected to the threaded post 3. A sliding frame 33 is provided on the threaded push rod 32.

[0028] The transmission assembly 25 consists of pulleys disposed on the rotating rod 21 and the connecting rod 24 and belts sleeved on the two pulleys.

[0029] Multiple support seats 12 are used to statically support the diesel engine. The transmission mechanism is used to horizontally transport the diesel engine in a unidirectional manner. The lifting mechanism is used to control the lifting of the sliding frame 33. In conjunction with the transmission mechanism, the diesel engine can be moved and the stability of the movement can be ensured.

[0030] The part requiring a description is the spring assembly 26, which in this invention is used to push or pull the working plate 23, causing the working plate 23 to engage with the threaded sleeve 22 via threaded transmission. This is done when the threaded sleeve 22 is located... Figure 3 When the left side of the disengagement zone 2302 is reached, the spring assembly 26 is in a stretched state. Combined with the forward rotation of the rotating rod 21, it can engage the working plate 23 with the threaded sleeve 22. Similarly, when the threaded sleeve 22 is located in... Figure 3 When the right side of the disengagement zone 2302 is reached, the spring assembly 26 is in a compressed state. Combined with the reverse rotation of the rotating rod 21, it can engage the working plate 23 with the threaded sleeve 22. The working plate 23 is positioned towards... Figure 3 The movement to the left is considered as the forward rotation of the rotating rod 21. The two ends of the threaded sleeve 22 are equipped with bearings that are resistant to thread wear, which reduces the wear between the threaded sleeve 22 and the threaded area 2301.

[0031] The working plate 23 is provided with a threaded area 2301 that is threadedly connected to the working plate 23. The threaded area 2301 is used for threaded transmission with the threaded sleeve 22.

[0032] The workbench 1 is provided with a sliding plate 11 for supporting the work plate 23, and the work plate 23 is slidably connected to the sliding plate 11. The sliding plate 11 provides stable support for the work plate 23, ensuring the stability of the movement of the work plate 23.

[0033] Limiting rods 34 are symmetrically arranged on the working plate 23, and limiting grooves that slide with the limiting rods 34 are symmetrically opened at the bottom of the sliding frame 33. The limiting rods 34 limit the vertical lifting of the sliding frame 33 to ensure the support effect on the diesel engine.

[0034] The workbench 1 is equipped with a safety crossbar 36 to limit the upward position of the sliding frame 33. The safety crossbar 36 is used to limit the lifting height of the sliding frame 33 to ensure the safety of the equipment.

[0035] The workbench 1 is provided with a sliding groove, and the sliding groove is slidably connected to the sliding frame 33, which limits the sliding trajectory of the sliding frame 33.

[0036] Working principle: Step 1, transportation: transport the diesel engine to the workbench 1 and support it by the top of the sliding frame 33;

[0037] Step 2: After transportation is completed, the surface connection structure of the diesel engine is sealed, followed by spraying.

[0038] Step 3, perform the displacement transmission: Start the stepper motor 2 to drive the rotating rod 21 to rotate, so that the threaded sleeve 22 engages with the threaded area 2301 of the working plate 23. That is, the working plate 23 drives the top limit rod to slide along the slide groove. At this time, the diesel engine deviates from the initial position relative to the worktable 1. When the threaded area 2301 of the working plate 23 disengages from the threaded sleeve 22, that is, the threaded sleeve 22 is located at... Figure 3 In the right-side disengagement zone 2302, the rotation of the threaded sleeve 22 will not cause the working plate 23 to move. The working plate 23 is in a horizontal stationary state, and at this time the third bevel gear 3101 meshes with the first bevel gear 2401.

[0039] Step 4: Lifting and lowering operation is carried out. The transmission component 25 drives the connecting rod 24 to rotate. The rotating first bevel gear 2401 drives the third bevel gear 3101 to rotate, which drives the internal thread column 3 to rotate in the forward direction. The internal thread column 3 and the bottom thread of the threaded top rod 32 rotate, thereby driving the sliding frame 33 to descend until multiple support seats 12 support the diesel engine, completing the misalignment of the diesel engine and facilitating the spraying work on the bottom of the diesel engine.

[0040] Step 5: Perform the reset operation. Start the stepper motor 2, which drives the rotating rod 21 to rotate in the opposite direction. Under the action of the spring assembly 26, the threaded sleeve 22 is pushed to contact the threaded area 2301 of the working plate 23, thereby allowing the working plate 23 to continue thread transmission and causing the threaded sleeve 22 to reach the desired position. Figure 3 In the left-side disengagement zone 2302, the third bevel gear 3101 meshes with the bevel gear transmission component 3102. The rotating rod 21, which rotates in the opposite direction, will drive the connecting rod 24 to rotate in the opposite direction. Through the meshing of the second bevel gear 2402 with the third bevel gear 3101, the third bevel gear 3101 is driven to rotate, thereby driving the internal thread column 3 to rotate in the forward direction, that is, driving the top sliding frame 33 to lift, thus lifting the diesel engine.

[0041] In multiple spraying operations, steps 3-5 are repeated each time to complete the work.

[0042] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
