Description

Technical Field

[0001] This utility model relates to the field of automotive parts processing technology, and in particular to a flipping tooling suitable for automotive connecting rods of different specifications. Background Technology

[0002] The name "flipping fixture for automotive connecting rods of different specifications" refers to the fact that the connecting rod is a core force-transmitting component in an automotive engine that connects the piston and crankshaft. Its machining accuracy directly affects the engine's operating efficiency and stability. The flipping fixture is a special auxiliary device used to clamp and flip the connecting rod during the machining process. Different specifications emphasize that the fixture must be adaptable to connecting rods with different parameters such as length, bore diameter, and thickness, and has wide versatility.

[0003] The core application of this device is in the batch processing of automotive connecting rods. It stably clamps connecting rods of different specifications and precisely flips them to specific angles according to processing requirements, enabling machining equipment to perform milling, boring, and tapping operations on different end faces of the connecting rods. In existing technologies, dedicated tooling—meaning one tooling unit corresponds to only one type of connecting rod—requires machine downtime to change the entire tooling set when processing different connecting rod specifications. However, dedicated tooling has extremely poor versatility. When the production line needs to switch to different connecting rod specifications, changing the tooling is not only time-consuming, but manual flipping is limited by the stability and precision of human operation, resulting in large flipping angle errors, making it difficult to meet high-precision processing requirements, and extremely low efficiency. These problems directly lead to extended production changeover cycles, significantly increased production costs for enterprises, and severely restrict the efficient and flexible production development of the automotive parts manufacturing industry. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a flipping fixture suitable for automotive connecting rods of different specifications, aiming to improve the problem that manual flipping in the prior art is limited by the stability and accuracy of manual operation.

Then, the driven motor provides power to drive the drive bevel gear and the driven bevel gear meshing with it, which in turn drives the rotating shaft, causing the control connecting rod to rotate. Under the restriction of the slide rail blocks, multiple sliders move to the opposite end under the rotation of the control connecting rod. The movement ends when they reach the inner wall of the car connecting rod, thereby fixing and clamping the car connecting rod, reducing the cost of use and improving practicality.

[0030] 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.

[0031] Please see the appendix Figure 1 and attached Figure 3 This utility model provides an embodiment of a flipping fixture suitable for automotive connecting rods of different specifications, including a support base plate 1, a plurality of fixing blocks 5 fixedly connected to the top of the support base plate 1, a drive motor 3 fixedly connected to the top of the support base plate 1, a rotating disk 4 fixedly connected to the output end of the drive motor 3, the right side of the rotating disk 4 rotatably connected to the left side of the fixing blocks 5, a worm gear 6 rotatably connected between adjacent fixing blocks 5, a handle 7 fixedly connected to the right side of the worm gear 6, a turbine 9 meshing with the inner wall of the worm gear 6, a connecting rod 10 fixedly connected to the inner wall of the turbine 9, a hollow plate 8 rotatably connected to the outer wall of the connecting rod 10, the bottom of the hollow plate 8 fixedly connected to the top of the rotating disk 4, a plurality of supporting connecting rods 11 fixedly connected to the outer wall of the connecting rod 10, and an inner support mechanism 2 fixedly connected to the top of the supporting connecting rods 11. The inner support mechanism 2 is used to clamp the automotive connecting rod.

[0032] Specifically, this flipping fixture can stably clamp and flip automotive connecting rods of different specifications at multiple angles. The support base plate 1 provides stable support for the entire assembly, while the top fixing block 5 provides auxiliary fixation. When the drive motor 3 is working, it can drive the rotating disk 4 to rotate. The rotating disk 4 is rotatably connected to the fixing block 5, ensuring stability during the flipping process and thus enabling angle adjustment of the connecting rod. Rotating the handle 7 can drive the worm gear 6 to rotate. The worm gear 6 meshes with the turbine 9, which in turn causes the turbine 9 to drive the connecting rod 10 to rotate. The connecting rod 10 drives the inner support mechanism 2 through the support connecting rod 11. The inner support mechanism 2 can adapt to connecting rods of different specifications, firmly clamping them and preventing displacement during flipping. The hollow plate 8 supports the connecting rod 10, ensuring the overall structural stability and meeting the flipping and fixing requirements during connecting rod processing.

[0033] Please see the appendix Figure 4 and attached Figure 5 The inner support mechanism 2 includes a support base 201. A driven motor 202 is fixedly connected to the top of the support base 201. A drive bevel gear 203 is fixedly connected to the output end of the driven motor 202. A driven bevel gear 204 is meshed with the inner wall of the drive bevel gear 203. A rotating shaft 205 is fixedly connected to the inner wall of the driven bevel gear 204. A plurality of control links 206 are rotatably connected to the top of the rotating shaft 205. A slider 207 is rotatably connected to the far end of each of the plurality of control links 206. A slide rail block 208 is slidably connected to the outer wall of the slider 207. A protective cover 209 is fixedly connected to the bottom of the slide rail block 208.

[0034] Specifically, the inner support mechanism 2 is used to clamp connecting rods of different specifications. The support base 201 provides stable support for it. When the driven motor 202 is working, it drives the drive bevel gear 203 to rotate. The drive bevel gear 203 meshes with the driven bevel gear 204, causing the driven bevel gear 204 to drive the rotating shaft 205 to rotate. When the rotating shaft 205 rotates, it drives multiple control linkages 206 to move. The control linkages 206 push the slider 207 to slide within the slide rail block 208. By sliding the slider 207, the clamping range can be adjusted to accommodate connecting rods of different specifications. The protective cover 209 provides protection and ensures the stable operation of the internal components, achieving a secure clamping of the connecting rod.

[0035] Please see the appendix Figure 1 and attached Figure 2 A clamping block 12 is fixedly connected to the bottom of the support base plate 1, and an electrical box 15 is fixedly connected to the top of the support base plate 1. An anti-electric door 16 is rotatably connected to the inner wall of the electrical box 15. A door handle 17 is fixedly connected to the front side of the anti-electric door 16. A controller 18 is fixedly connected to the front side of the clamping block 12. The controller 18 is electrically connected to the drive motor 3 and the driven motor 202 respectively.

[0036] Specifically, the clamping block 12 at the bottom of the support base plate 1 is used to fix the tooling, the top electrical box 15 protects the internal electrical appliances, and the anti-electric door 16 can be opened and closed through the door handle 17 for easy maintenance. The controller 18 on the front side of the clamping block 12 is electrically connected to the drive motor 3 and the driven motor 202, which can control the motor operation and realize the automated operation of flipping and clamping, ensuring the stable operation of the tooling.

[0037] Please see the appendix Figure 1 and attached Figure 2 The bottom of the support base plate 1 is fixedly connected with multiple support legs 13, and the bottom end of the support legs 13 is fixedly connected with foot pads 14. The top of the hollow plate 8 is fixedly connected with a utility pole 19, and the top of the utility pole 19 is fixedly connected with a lampshade 20. The inner wall of the lampshade 20 is threaded with a lighting lamp 21. The inner wall of the control linkage 206 is provided with multiple weight-reducing grooves 22. The bottom of the protective cover 209 is fixedly connected to the top of the support base 201.

[0038] Specifically, the support feet 13 and bottom pads 14 at the bottom of the base plate 1 enhance the stability of the tooling placement and reduce vibration. The pole 19 on the top of the hollow plate 8 supports the lampshade 20, and the lighting lamp 21 inside the lampshade 20 provides illumination for easy operation. The weight reduction groove 22 of the control linkage 206 reduces weight and saves energy. The protective cover 209 is fixed to the support base 201 to securely protect the internal components and ensure the operation of the tooling.

[0039] Working principle: First, observe the working environment, then determine the required angle. When the left and right angles need to be adjusted, manually turn the handle 7 to provide power, which in turn drives the worm gear 6 between the two fixed blocks 5, and simultaneously drives the turbine 9 connected to it to rotate. Then, the connecting rod 10 drives the support connecting rod 11 to rotate. When the up and down angles need to be adjusted, the stepper motor 3 provides power to drive the rotating disk 4 to rotate, which in turn drives the hollow plate 8 on it to achieve angle adjustment. When simultaneous operations are required, the above operations can be performed at the same time, allowing work to be carried out at any angle, reducing manual operation, lowering operating costs, and improving efficiency.

[0040] First, the car connecting rod that needs to be fixed and clamped is placed between the centers of multiple slide rail blocks 208. Then, the driven motor 202 provides power to drive the drive bevel gear 203 and the driven bevel gear 204 that meshes with it, which in turn drives the rotating shaft 205, causing the control connecting rod 206 to rotate. Under the constraint of the slide rail blocks 208, multiple sliders 207 move to the opposite end under the rotation of the control connecting rod 206. The movement ends when they reach the inner wall of the car connecting rod, thereby fixing and clamping the car connecting rod, reducing the cost of use and improving practicality.

[0041] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
