Description

Technical Field

[0001] This utility model belongs to the field of engine assembly technology. Specifically, this utility model relates to a piston connecting rod traction guide fixing tool. Background Technology

[0002] In every engine manufacturer, each engine requires the assembly of piston connecting rods. Many companies use traditional manual joining and hoisting methods, which are inefficient, slow, and labor-intensive. Therefore, there is an urgent need to design a new, fast, and efficient assembly method.

[0003] During the production process, piston connecting rods require tools for installation. These tools must be simple to operate, easy to use, efficient, high-quality, safe, and reliable. Existing piston connecting rod tools cannot guarantee that the piston connecting rod will be fully aligned when inserted, making them time-consuming, labor-intensive, and inefficient, failing to meet production and quality requirements. Furthermore, current piston connecting rod tools cannot guarantee that the connecting rod is fully aligned when picking it up, which can easily lead to skewness, movement, and the risk of impact, knocking, or chipping off the crankshaft.

[0027] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings, in order to help those skilled in the art to have a more complete, accurate and in-depth understanding of the concept and technical solution of this utility model, and to facilitate its implementation.

[0028] like Figures 1 to 3 As shown, this utility model is a piston connecting rod traction guide and fixing tool. It uses the guiding and fixing function to guide the piston connecting rod to avoid impact and collision with the crankshaft. It is simple to use, easy to operate, and highly efficient.

[0029] Specifically, such as Figures 1 to 3As shown, it includes a base 1 and a first guide block 2, which is fixedly connected to the top of one side of the base 1 by a first bolt;

[0030] Fixing component 3 is fixedly connected to one side of the top of the base;

[0031] Fixed component 3 includes

[0032] A fixed shaft 31 is fixedly connected to one side of the top of the base 1, and two limiting ports 311 are opened at one end of the fixed shaft 31.

[0033] A pivot pin 32 passes through both ends of a fixed shaft 31;

[0034] Two limiting cylinders 33 are respectively sleeved on both ends of the shaft pin 32. Two locking pins 331 are provided on one side of one limiting cylinder 33, and the two locking pins 331 are riveted to the two limiting ports 311 respectively.

[0035] Spring 34 is sleeved on the surface of shaft pin 32;

[0036] Two spring clips 35 are respectively disposed on both sides of the surface of the shaft pin 32;

[0037] Self-locking clamp 36, the self-locking clamp 36 is fixedly connected to the top of the two limiting cylinders 33;

[0038] The second guide block 37 is fixedly connected to one side of the self-locking clamp 36 by the second bolt.

[0039] A pull rope 4 is fixedly connected to the bottom of the base 1, and the first guide block 2 and the second guide block 37 can be replaced according to different specifications of piston connecting rods;

[0040] The single-sided spring 34 is for easy disassembly and adjustment, while the absence of a spring 34 on the other side is to avoid interference with the spray hook.

[0041] The specific working method is described below using specific embodiments: Example 1

[0042] In use, by pushing the self-locking clamp 36 outward, the limiting cylinder 33 drives the pin 32 to slide outward along the fixed shaft 31. During the outward movement of the limiting cylinder 33, the spring 34 is compressed. When the locking pin 331 on the limiting cylinder 33 disengages from the limiting port 311 on the fixed shaft 31, the self-locking clamp 36 is rotated, causing the pin 32 to rotate along the fixed shaft 31 as its axis. After rotating to a predetermined angle, the self-locking clamp 36 is released, and under the action of the spring 34's own deformation restoring force... This causes the locking pin 331 to abut against one end of the fixed shaft 31, thereby temporarily fixing the self-locking clamp 36. Finally, the piston connecting rod that needs to be guided is placed on the base 1. By rotating the self-locking clamp 36, the shaft pin 32 rotates along the axis of the fixed shaft 31 until the locking pin 331 on the limiting cylinder 33 engages with the limiting port 311 on the fixed shaft 31, thus completing the clamping and fixing of the piston connecting rod. The pull rope 4 is to facilitate the removal of the entire tooling after the piston connecting rod is inserted.
