Description

Technical Field

[0001] This utility model relates to the field of connecting rod cover assembly technology, and in particular to an engine connecting rod cover assembly fixture. Background Technology

[0002] Connecting rod fracture technology is a new manufacturing process for connecting rods, representing a significant transformation of traditional processing techniques and becoming an important indicator of the development level of the engine connecting rod manufacturing industry. Due to the regular fracture at the notch, the fracture surface of the fractured connecting rod exhibits a jagged, interlocking characteristic. Positioning is achieved through the interlocking of these fracture surfaces, resulting in more precise positioning and eliminating the need for traditional locating pins. Furthermore, the uneven fracture surface after fracture increases the area of ​​the mating surface between the connecting rod cap and the connecting rod, thereby increasing the connecting rod's load-bearing capacity and shear resistance. Achieving these effects requires complete engagement of the fracture surfaces during assembly of the connecting rod cap and connecting rod body. Protecting the meshing surfaces during assembly ensures complete engagement between the connecting rod cap and connecting rod body, improving assembly quality and playing a crucial role in enhancing the overall engine performance. Currently, for ease of installation, connecting rod caps often require auxiliary installation using assembly fixtures.

[0003] Existing connecting rod cover assembly fixtures are mostly fixed in size and can only be used to install connecting rod covers of a specific size, resulting in poor overall practicality. Therefore, this application provides an engine connecting rod cover assembly fixture to meet the requirements. Utility Model Content

[0033] like Figure 1 , Figure 2 and Figure 3 As shown, an embodiment of this utility model provides an engine connecting rod cover assembly fixture, including a fixture body 1. Handles 2 are symmetrically fixed to both sides of the fixture body 1, corresponding to the top of the fixture body 1. Clamping blocks 5 are symmetrically protruding from the bottom of the fixture body 1. A snap-fit ​​groove for the connecting rod cover 14 is provided between the two clamping blocks 5. A cam connecting rod 15 is installed below the connecting rod cover 14. A protruding block is provided on the inner side of the clamping block 5. A sliding cavity is formed at the bottom of the fixture body 1. A sliding block 51 is protruding from the top of the clamping block 5 and is slidably disposed in the sliding cavity. A sliding groove is formed on one side of the fixture body 1, and the sliding cavity communicates with the sliding groove. One side of the sliding block 51 is disposed in the sliding cavity. A protruding seat 11 is provided on the side of the body 1 corresponding to the sliding block 51. A transmission component 6 for adjusting the position of the sliding block 51 is provided inside the protruding seat 11. The transmission component 6 includes a bidirectional lead screw 8 that is horizontally fixed on the protruding seat 11. A protrusion 7 is provided on one side of the sliding block 51 in the slide groove. The bidirectional lead screw 8 is installed on the protrusion 7. The protrusion 7 and the bidirectional lead screw 8 are threaded together. A worm gear 10 is installed on the protruding seat 11. A worm wheel 9 is sleeved on the bidirectional lead screw 8. The worm wheel 9 and the worm gear 10 are driven together. A top pressure rod 3 is installed at the center of the tooling body 1. A knob 31 is protruding at the top of the top pressure rod 3. The tooling body 1 and the top pressure rod 3 are threaded together.

[0034] By cooperating with the clamping blocks 5 and transmission components 6 on the tooling body 1, the connecting rod cover 14 is placed between the two clamping blocks 5 and above the protruding block. The worm gear 10 is rotated, and the worm gear 10 and the worm wheel 9 are driven to rotate the worm wheel 9 as a whole. The worm wheel 9 drives the double-acting screw 8 to rotate as a whole. The protruding block 7 is threadedly engaged with the double-acting screw 8, which causes the protruding block 7 to move as a whole. When the protruding block 7 moves, it drives the sliding block 51 to move, and the clamping blocks 5 to move as a whole. This allows the connecting rod cover 14 to be stably clamped and installed on the protruding block of the clamping block 5. During operation, the distance between the two clamping blocks 5 can be effectively adjusted according to the size of the connecting rod cover 14, thus adapting to the overall installation of connecting rod covers 14 of different sizes and improving the overall practicality of the device.

[0035] The aforementioned tooling body 1 has a through-hole sliding cavity, a slider 43 is slidably arranged in the sliding cavity, a rotating rod 4 is installed through the slider 43, a sleeve 41 is fixed at the top of the rotating rod 4, and a spiral cylinder 42 for driving the screw to tighten is fixed at the bottom of the rotating rod 4. A limit strip is symmetrically and horizontally protruding in the sliding cavity, and a limit groove for the limit strip to slide is opened on the slider 43.

[0036] By setting up a sliding slider 43 and a rotating rod 4 that slides on it, the connecting rod bolts at different positions can be easily fixed during operation, which can adapt to the overall installation requirements of connecting rod covers 14 of different sizes and improve the overall practicality of the device.

[0037] like Figure 1 and Figure 4 As shown, a scale plate 12 is embedded and installed on the outer side of the tooling body 1 and above the corresponding slide groove. A pointer 13 is protruding on the protrusion 7. The scale plate 12 and the pointer 13 cooperate to point. Length scale lines are engraved on the scale plate 12.
