Technical Field

[0001] This utility model relates to the field of elastic connecting rod installation technology, and in particular to a positioning and installation device for elastic connecting rods of various types of diesel engines. Background Technology

[0002] As the most important speed-regulating moving component of medium- and high-speed diesel engines, the installation, disassembly, and length accuracy of the flexible connecting rod are among the most important assembly steps of diesel engines. Therefore, it is essential to ensure the ease of installation and disassembly of the flexible connecting rod and the accuracy of its length, as this ensures the accuracy of the main engine's fuel injection quantity.

[0003] Traditional installation methods rely on manual measurement of hole center distance using calipers or rulers, which can result in significant errors. This can lead to deviations in the piston movement trajectory, causing problems such as increased cylinder liner wear and incomplete combustion. In addition, the length of the elastic connecting rod varies significantly between different diesel engine models, requiring customized tooling, which not only increases the cost of model replacement.

[0004] Therefore, it is necessary to provide a new positioning and installation device for flexible connecting rods of various types of diesel engines to solve the above-mentioned technical problems. Utility Model Content

The first spring is sleeved on the outer wall of the first connecting rod. One end of the first spring is fixedly connected to the fixing block, and the other end of the first spring is fixedly connected to the connecting plate. The second connecting rod is fixedly connected to one side of the connecting plate, and a rubber pad is fixedly connected to one end of the second connecting rod.

[0008] Preferably, the limiting structure includes: a pressing rod, a third connecting rod, a second spring, and a limiting ball. The pressing rod is slidably connected inside the sleeve, and the third connecting rod is fixedly connected to the bottom of the pressing rod. The end of the third connecting rod away from the pressing rod is fixedly connected to the slide rod. The outer wall of the third connecting rod is fitted with a second spring. One end of the second spring is fixedly connected to the sleeve, and the other end of the second spring is fixedly connected to the slide rod. The limiting ball is equidistantly slidably connected inside the sleeve.

It should be understood that the specific embodiments described herein are merely for explaining the present utility model and are not intended to limit the present utility model.

[0027] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0028] Please see Figures 1 to 4 A positioning and installation device for a multi-type diesel engine elastic connecting rod includes: a fixing plate 1, a sliding groove 2 on the top of the fixing plate 1, an elastic connecting rod body 3 mounted on the top of the fixing plate 1, an insertion hole 4 on the top of the fixing plate 1, a slider 5 slidably connected to the fixing plate 1 through the sliding groove 2, a positioning bolt 6 rotatably connected to the top of the slider 5, a sleeve 7 mounted on the top of the fixing plate 1, a sliding rod 8 slidably connected inside the sleeve 7, a compression structure for compressing the side wall of the sliding groove 2 symmetrically installed inside the slider 5, a limiting structure for fixing the sleeve 7 installed inside the sleeve 7 and the fixing plate 1, a thread on the top of the sleeve 7, and the sleeve 7 threadedly connected to the elastic connecting rod body 3, and a limiting groove 81 inside the insertion hole 4.

[0029] It should be noted that: the fixed plate 1 serves as the base of the entire device, and the slide groove 2 opened on its top provides a sliding track for the slider 5, ensuring that the slider 5 can move along the slide groove 2 to the designated position. The insertion hole 4 on the top of the fixed plate 1 provides an installation interface for the sleeve 7. The sleeve 7 is first threadedly connected to the elastic connecting rod body 3 through the top thread.

[0030] Please see Figure 1 , Figure 2 and Figure 4 The extrusion structure includes: a connecting plate 21, a first connecting rod 22, an extrusion plate 23, a fixing block 24, a first spring 25, a second connecting rod 26, and rubber pads 27. The connecting plate 21 is symmetrically slidably connected inside the slider 5. The first connecting rod 22 is fixedly connected to one side of the connecting plate 21. One end of the first connecting rod 22 passes through the slider 5 and is fixedly connected to the extrusion plate 23. The fixing block 24 is fixedly connected inside the slider 5. The first spring 25 is sleeved on the outer wall of the first connecting rod 22. One end of the first spring 25 is fixedly connected to the fixing block 24, and the other end of the first spring 25 is fixedly connected to the connecting plate 21. The second connecting rod 26 is fixedly connected to one side of the connecting plate 21. One end of the second connecting rod 26 is fixedly connected to the rubber pad 27. Both rubber pads 27 pass through the slider 5 and contact the side wall of the groove 2.

[0031] It should be noted that when sliding slider 5 needs to be moved, press the extrusion plates 23 on both sides of slider 5. The extrusion plates 23 drive the connecting plate 21 to move through the first connecting rod 22. At this time, the first spring 25 is stretched. When the connecting plate 21 moves, it drives the rubber pad 27 to move through the second connecting rod 26, so that the rubber pad 27 no longer contacts the side wall of the slide groove 2. The movement of slider 5 is no longer restricted. After slider 5 reaches the designated position, release the extrusion plates 23. The first spring 25 drives the connecting plate 21 to reset, and the rubber pad 27 re-extrudes the side wall of the slide groove 2.

[0032] Please see Figures 1 to 3 The limiting structure includes: a pressing rod 31, a third connecting rod 32, a second spring 33, and limiting balls 34. The pressing rod 31 is slidably connected inside the sleeve 7. The bottom of the pressing rod 31 is fixedly connected to the third connecting rod 32. The end of the third connecting rod 32 away from the pressing rod 31 is fixedly connected to the slide rod 8. The outer wall of the third connecting rod 32 is fitted with the second spring 33. One end of the second spring 33 is fixedly connected to the sleeve 7, and the other end of the second spring 33 is fixedly connected to the slide rod 8. Limiting balls 34 are equidistantly slidably connected inside the sleeve 7. Multiple sets of the limiting balls 34 and the pressing rod 31 all penetrate the sleeve 7.

[0033] It should be noted that: in the initial state, the limiting ball 34 is squeezed by the outer wall of the slide rod 8, and the limiting ball 34 is exposed to the outside. At this time, the operator presses the pressing rod 31, and the pressing rod 31 pushes the slide rod 8 down through the third connecting rod 32. The second spring 33 is stretched, and the slot 61 on the slide rod 8 comes to the same level as the limiting ball 34. Then the sleeve 7 is inserted into the insertion hole 4, and the inner wall of the insertion hole 4 squeezes the limiting ball 34, causing the limiting ball 34 to enter the slot 61.

[0034] The working principle of the multi-type diesel engine elastic connecting rod positioning and installation device provided by this utility model is as follows:

[0035] Limiting structure:

[0036] The insertion hole 4 at the top of the fixing plate 1 provides an installation interface for the sleeve 7. The sleeve 7 is first connected to the elastic connecting rod body 3 by the top thread. In the initial state, the limiting ball 34 is squeezed by the outer wall of the sliding rod 8, and the limiting ball 34 is exposed to the outside. At this time, the operator presses the pressing rod 31, and the pressing rod 31 pushes the sliding rod 8 down through the third connecting rod 32. The second spring 33 is stretched, and the groove 61 on the sliding rod 8 comes to the same level as the limiting ball 34. Then the sleeve 7 is inserted into the insertion hole 4, and the inner wall of the insertion hole 4 squeezes the limiting ball. 34. The limiting ball 34 is inserted into the slot 61 until it reaches the same level as the limiting groove 81. Then, the pressing rod 31 is released, the second spring 33 is reset and drives the sliding rod 8 to reset, so that the limiting ball 34 gradually disengages from the slot 61. At the same time, the outer wall of the sliding rod 8 pushes the limiting ball 34 into the limiting groove 81. Through the engagement of the limiting ball 34 and the limiting groove 81, the sleeve 7 is fixed inside the insertion hole 4, thus completing the fixation of the sleeve 7. To release the sleeve 7, simply press the pressing rod 31 to remove the sleeve 7 from the fixing plate 1.

[0037] Extrusion structure:

[0038] The fixed plate 1 serves as the base of the entire device. The groove 2 on its top provides a sliding track for the slider 5, ensuring that the slider 5 can move along the groove 2 to the designated position. When the slider 5 needs to be moved, the pressing plates 23 on both sides of the slider 5 are pressed. The pressing plates 23 drive the connecting plate 21 to move through the first connecting rod 22. At this time, the first spring 25 is stretched. When the connecting plate 21 moves, it drives the rubber pad 27 to move through the second connecting rod 26, so that the rubber pad 27 no longer contacts the side wall of the groove 2. The movement of the slider 5 is no longer restricted. After the slider 5 reaches the designated position, the pressing plates 23 are released. The first spring 25 drives the connecting plate 21 to reset. The rubber pad 27 re-presses the side wall of the groove 2. The positioning bolt 6 on the top of the slider 5 is threaded to the elastic connecting rod body 3. The positioning bolt 6 and the sleeve 7 complete the fixation of the elastic connecting rod body 3.
