Description

Technical Field

[0001] This utility model relates to the field of assembly tooling technology, specifically a tooling for installing handle steps on the crossbeam component of a diesel engine base frame. Background Art

[0002] As one of the three major key components of a marine diesel engine, the engine base and frame play a crucial role in the engine's operation. If a diesel engine malfunctions during operation, maintenance personnel need to enter the engine for repairs. The handles and steps on the engine base and frame crossbeams are the main access routes for these personnel. Therefore, these handles and steps need to be systematically arranged on the engine base and frame crossbeams to facilitate easy access for maintenance personnel to the engine.

[0003] The installation of hand pedals on the common diesel engine mount frame mainly relies on workers using measuring tools such as tape measures to determine the installation position of each handle on the crossbeam component according to the drawings. However, due to the different models of diesel engines, workers need to remeasure and position the installation dimensions of the handle pedals on the crossbeam when installing the pedals for different diesel engines. Moreover, this measurement and positioning process often requires two people to work together, which is time-consuming, labor-intensive, and has a high error rate, and cannot meet the work requirements of assembly tooling. Therefore, a tooling for installing hand pedals on the crossbeam component of diesel engine mount frame is proposed. Utility Model Content

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] This utility model provides a technical solution: a tooling for installing handle steps on the crossbeam component of a diesel engine base frame, comprising a guide rail 1, a positioning block 2, a permanent magnet block 3, a slider 4, an assembly plate 5, a snap-fit ​​seat 6, a scale line 7, a limit bolt 8, a through groove 9, a damping shaft 10, a side plate 11, a transmission block 12, a base plate 13, a slide groove 14, a snap-fit ​​block 15, a pressing seat 16, a hinge shaft 17, a first spring 18, a connecting rod 19, a square plate 20, a circular plate 21, and a second spring 22.

[0030] Please see Figure 1 The left end of guide rail 1 is connected to positioning block 2, and the right side of guide rail 1 is equipped with permanent magnet block 3 via an iron chain. Please refer to [link / reference]. Figure 2 The guide rail 1 is equipped with a slider 4. The guide rail 1 is U-shaped. There are 4-8 sets of sliders 4, and the sliders 4 are all U-shaped.

[0031] Assembly plate 5 is mounted on the top of slider 4. Snap-fit ​​seats 6 are installed on both the left and right sides of the upper surface of assembly plate 5. Please refer to [link / reference]. Figure 3 Limit bolts 8 are screwed onto the inner side of the snap-fit ​​seat 6;

[0032] Please see Figure 2 Scale line 7 is mounted on the top left side of guide rail 1. Please refer to [link / reference]. Figure 3 The assembly plate 5 has through slots 9 on both its left and right sides, corresponding to the positions of the snap-fit ​​seats 6. The guide rail 1 is mounted on the surface of the base using the permanent magnet block 3 and the positioning block 2. The position between the assembly plate 5 and the slider 4 is then adjusted according to the scale lines 7. The step to be installed is then inserted into the through slots 9 and snap-fit ​​seats 6. Finally, the limiting bolts 8 are tightened to complete the installation of the step. Please refer to [link / reference]. Figure 8 After multiple handles are fixed, their bottoms can be welded to ensure that the steps are fully connected to the diesel engine base. This not only improves the ease of step installation, but also ensures high installation accuracy between steps due to the cooperation of scale line 7 and slider 4.

[0033] Please see Figure 4 Damping shafts 10 are inserted into the middle positions inside both slider 4 and mounting plate 5. Please refer to [link / reference]. Figure 5 A base plate 13 is inserted into the bottom of slider 4, and side plates 11 are inserted into the lower parts of both the left and right sides of slider 4. A transmission block 12 is coaxially mounted at the bottom end of damping shaft 10. Please refer to [link / reference]. Figure 6 The base plate 13 has sliding grooves 14 on both the left and right sides inside, and each sliding groove 14 has a locking block 15 inserted inside. Each locking block 15 has a pressing seat 16 mounted on its top. The transmission block 12 is teardrop-shaped. The front and rear sides of the pressing seat 16 are connected to hinge shafts 17, and each hinge shaft 17 is fitted with a first spring 18. Please refer to [link / reference]. Figure 7 A connecting rod 19 is installed on the inner center of each side plate 11, and a square plate 20 is installed on the inner end of each connecting rod 19. Cylindrical grooves are opened on the left and right sides of the slide groove 14 corresponding to the positions of the connecting rod 19. A circular plate 21 is coaxially installed on the outer right side of the connecting rod 19, and a second spring 22 is sleeved on the outer left side of the connecting rod 19. After the slider 4 is positioned by the scale line 7, the damping shaft 10 is rotated to drive the transmission block 12 to rotate, thereby pushing the extrusion seat 16 to expand outward. This allows the square plate 20 to drive the connecting rod 19 and the side plate 11 to expand outward synchronously. In turn, the side plate 11 can clamp the slider 4 inside the guide rail 1, preventing the slider 4 from moving inside the guide rail 1 after positioning, thus improving the stability and accuracy of the step welding.

[0034] This solution uses permanent magnet block 3 and positioning block 2 to mount guide rail 1 on the surface of engine base. Then, the position between assembly plate 5 and slider 4 is adjusted according to scale line 7. The step to be installed is then inserted into through slot 9 and snap-fit ​​seat 6. Finally, the limiting bolt 8 is tightened to complete the installation of the step. This allows the bottom of the step to be welded after multiple handles are fixed, so that the step is completely connected to the engine base of the diesel engine. This not only improves the convenience of step installation, but also ensures high installation accuracy between steps due to the cooperation of scale line 7 and slider 4. Furthermore, after positioning slider 4 through scale line 7, the damping shaft 10 is rotated to drive the transmission block 12 to rotate, thereby pushing the extrusion seat 16 to expand outward. This allows the square plate 20 to drive the connecting rod 19 and side plate 11 to expand outward synchronously. In turn, the side plate 11 can clamp slider 4 inside guide rail 1, preventing slider 4 from moving inside guide rail 1 after positioning, thus improving the stability and accuracy of step welding.
