Description

Technical Field

[0001] This utility model belongs to the field of engine connecting rod manufacturing technology, specifically a fixed structure for engine connecting rod manufacturing and processing. Background Technology

[0002] As a core transmission component of an internal combustion engine, the connecting rod plays a crucial role in connecting the piston and crankshaft. It converts the reciprocating linear motion of the piston into the rotational motion of the crankshaft and transmits the power generated during combustion. The manufacturing process of the connecting rod involves multiple steps such as cutting, grinding, drilling, and chamfering. Therefore, the connecting rod needs to be clamped by a fixing structure. If the fixing effect is not good, the connecting rod may be displaced or vibrated during the processing, which may lead to problems such as dimensional deviation and out-of-tolerance form and position, affecting the assembly adaptability and performance of the connecting rod.

[0003] Meanwhile, an engine connecting rod fixing device with application number CN201920960142.0 includes a support mechanism and a clamping mechanism. The support mechanism supports a platform, and a limiting member for fixing the connecting rod is provided on the support platform. The clamping mechanism includes a cylinder parallel to the support platform. A push block is provided at the top end of the piston rod of the cylinder, and the push block can clamp the connecting rod onto the limiting member as the piston rod extends.

[0004] However, the following problems were found in the implementation of the relevant technologies: Currently, some fixing structures generally use cylinder drive to fix the engine connecting rod. However, cylinder drive has certain shortcomings. The clamping force of cylinder drive is greatly affected by air pressure, and it is easy to cause certain errors in the machining of the engine connecting rod due to loosening of the clamp. The aforementioned engine connecting rod fixing device also has certain shortcomings. It uses a single-sided cylinder to drive a push block to clamp the engine connecting rod, but because cylinder drive is prone to loosening of the clamp, it can cause certain errors in the machining of the engine connecting rod. Furthermore, the push block is in direct contact with the engine connecting rod. Since both the push block surface and the engine connecting rod surface have a certain degree of hardness, sliding and displacement can easily occur during contact, further causing machining errors. Utility Model Content

[0005] To address the problems mentioned in the background section, this utility model provides an engine connecting rod manufacturing and fixing structure, which has the advantages of facilitating the clamping and fixing of engine connecting rods of different sizes and improving the contact friction with the engine connecting rod.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a fixed structure for the production and processing of engine connecting rods, including a workbench, a support base connected to the top of the workbench, a fixing component provided on the support base, a drive source connected to the top of the workbench, a connecting screw connected to the power output end of the drive source, a connecting block threadedly connected to the surface of the connecting screw through a screw nut, and a support ring connected to the surface of the support base. The surface of the fixing component is connected to the surface of the connecting block to drive the fixing component to move in opposite directions in the horizontal direction to clamp and fix the engine connecting rod.

[0007] Preferably, the fixing assembly includes four adapter rods, four first support frames, and a limiting rod. The four adapter rods are rotatably mounted on the surface of the connecting block. A fixing block is rotatably connected to the surface of every two adapter rods. Each pair of first support frames is rotatably mounted on the surface of each fixing block. A second support frame is rotatably connected to the surface of each of the four first support frames. A clamping block is rotatably connected to the surface of every two second support frames. A high-elasticity silicone pad is connected to the inner side of each clamping block. The limiting rod is mounted on the surface of the support base.

[0008] Preferably, the inner sides of both fixing blocks are slidably connected to the surface of the limiting rod.

[0009] Preferably, the two clamping blocks are symmetrically arranged on the front and rear sides of the vertical center line of the worktable.

[0010] Preferably, the motion trajectories of the two clamping blocks are respectively translated in opposite directions along the horizontal direction.

[0011] Preferably, a through groove is provided on one side of the support base, and the power output end of the drive source passes through the interior of the through groove.

[0012] Preferably, the inner side of the support ring is rotatably connected to the surface of the connecting screw.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: This invention uses a drive source to rotate the connecting screw, facilitating the horizontal translation of the connecting block. The rotation of the adapter rod causes the two fixed blocks to experience corresponding tensile forces, enabling them to move synchronously against the two clamping blocks to clamp and fix the engine connecting rod. This design is adaptable to different positions of the engine connecting rod and to engine connecting rods of different sizes, increasing flexibility. Two highly elastic silicone pads not only enhance the gentle contact force during engine connecting rod clamping but also increase the friction between the clamping blocks and the engine connecting rod, improving the stability of the engine connecting rod fixation, reducing machining errors, and facilitating subsequent processing of the engine connecting rod.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0017] like Figures 1 to 4 As shown, this utility model provides a fixed structure for the production and processing of engine connecting rods, including a workbench 1, a support base 3 connected to the top of the workbench 1, a fixing component 2 provided on the support base 3, a drive source 4 connected to the top of the workbench 1 to provide driving force for the fixing operation of the engine connecting rod, a connecting screw 5 connected to the power output end of the drive source 4, a connecting block 6 threadedly connected to the surface of the connecting screw 5 through a screw nut to facilitate the translation of the connecting block 6, and a support ring 7 connected to the surface of the support base 3. The surface of the fixing component 2 is connected to the surface of the connecting block 6 so as to drive the fixing component 2 to move in opposite directions in the horizontal direction to clamp and fix the engine connecting rod.

[0018] Specifically, the fixing component 2 includes four adapter rods 21, four first support frames 23, and a limiting rod 27. The four adapter rods 21 are rotatably mounted on the surface of the connecting block 6. A fixing block 22 is rotatably connected to the surface of every two adapter rods 21. Each pair of first support frames 23 is rotatably mounted on the surface of each fixing block 22. A second support frame 24 is rotatably connected to the surface of each of the four first support frames 23. The reinforcement and support of the first support frames 23 and the second support frames 24 help to improve the stability of the clamping block 25. A clamping block 25 is rotatably connected to the surface of every two second support frames 24. A high-elastic silicone pad 26 is connected to the inner side of each clamping block 25, which helps to increase the friction with the engine connecting rod. The limiting rod 27 is mounted on the surface of the support base 3.

[0019] Furthermore, the inner sides of both fixing blocks 22 are slidably connected to the surface of the limiting rod 27, providing support for the fixing blocks 22 and preventing the fixing blocks 22 from tilting.

[0020] Furthermore, the two clamping blocks 25 are symmetrically arranged on the front and rear sides of the vertical center line of the worktable 1, which facilitates the provision of symmetrical clamping and fixing forces for the engine connecting rod.

[0021] It is worth noting that the movement trajectories of the two clamping blocks 25 are respectively made in opposite directions along the horizontal direction, which facilitates the clamping and fixing of the engine connecting rod through symmetrical movement.

[0022] It is worth noting that a through slot is provided on one side of the support base 3, and the power output end of the drive source 4 passes through the inside of the through slot, so that the drive source 4 can drive the connecting screw 5 to rotate.

[0023] It is worth mentioning that the inner side of the support ring 7 is rotatably connected to the surface of the connecting screw 5, which facilitates the improvement of the rotational stability of the connecting screw 5.

[0024] Among them, the connecting screw 5 and the high-elastic silicone pad 26 are existing technologies and will not be described in detail; at the same time, this utility model also includes a power supply, controller and switch, etc., which are not the main technical points of this patent and will not be described in detail; the "front, back, left and right" perspectives of this device are as follows: Figure 1 The direction shown in the diagram is the reference.

[0025] Working principle: First, since the engine connecting rod has a larger end and a smaller end, assuming that the smaller end of the engine connecting rod is clamped and fixed, it is necessary to bring the two clamping blocks 25 closer together. Then, the drive source 4 drives the connecting screw 5 to rotate, thereby driving the connecting block 6, which is threaded to it, to move to the left. Then, under the rotational connection of the adapter rod 21, the two fixing blocks 22 are subjected to a leftward pulling force, so that the two fixing blocks 22 are driven to move closer to each other. Simultaneously, under the connection of the first support frame 23 and the second support frame 24, the two clamping blocks 25 are driven to move closer to each other to clamp and fix the engine connecting rod. The clamping blocks 25 are provided with high-elasticity silicone pads 26. Therefore, the two high-elasticity silicone pads 26 not only help to increase the clamping force on the engine connecting rod, but also help to increase the friction between the clamping blocks 25 and the engine connecting rod, thereby improving the stability of fixing the engine connecting rod, reducing processing errors, and facilitating subsequent processing of the engine connecting rod. Similarly, if the engine connecting rod is clamped and fixed at a position with a larger size, the connecting screw 5 is reversed by the drive source 4, which will push the four adapter rods 21 to the right, thereby causing the two fixing blocks 22 to separate in opposite directions, and thus causing the two clamping blocks 25 to separate in opposite directions. This expands the clamping size of the engine connecting rod, making it easier to clamp and fix different positions of the engine connecting rod, and also easier to clamp and fix engine connecting rods of different sizes, thus improving the flexibility of use.
