Detailed Implementation

[0027] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0028] First Embodiment

[0029] Please refer to the following: Figure 1 , Figure 2 , Figure 3 and Figure 4 ,in, Figure 1 A schematic diagram of the structure of a first embodiment of an automotive steering knuckle precision machining production line provided by this utility model; Figure 2 for Figure 1 A cross-sectional structural schematic diagram of the fixture shown; Figure 3 for Figure 2 The enlarged schematic diagram of part A shown below; Figure 4 for Figure 1 The enlarged schematic diagram of section B is shown. A precision machining production line for automotive steering knuckles includes:

[0030] The operating table 1 has a moving mechanism 2 inside, a drilling mechanism 3 on the top of the moving mechanism 2, and a limit mechanism 10 on the surface of the operating table 1.

[0031] A rotating frame 4 is disposed on the surface of the operating table 1. A plurality of support frames 41 are fixedly connected to one side of the rotating frame 4. A fixed frame 42 is fixedly connected to the surface of the rotating frame 4. A sliding groove 43 is provided inside the plurality of fixed frames 42. A fixing clamp 44 is slidably connected inside the plurality of sliding grooves 43. A plurality of fixing holes 9 are provided inside the rotating frame 4.

[0032] Multiple rotating holes 5 are respectively disposed inside multiple fixing frames 42, and rotating rods 6 are threadedly connected inside each of the multiple rotating holes 5;

[0033] A fixing groove 7 is provided inside the operating table 1, and a fixing pin 8 is slidably connected to the temporal part of the fixing groove 7.

[0034] The sliding groove 43 is a rectangular groove, and the fixing clip 44 is a rectangular block adapted to the sliding groove 43. It has a semi-circular slot adapted to the steering knuckle inside, which is used to limit the steering knuckle after the fixing clip 44 contacts the surface of the steering knuckle. At the same time, a protective pad 11 is fixedly connected to the surface of the fixing clip 44 to increase the friction between the fixing clip 44 and the steering knuckle, thereby increasing the fixing effect.

[0035] The rotating rod 6 is a threaded rod, and the rotating hole 5 is a threaded hole adapted to the rotating rod 6. When the rotating rod 6 rotates to one side, it can move inside the rotating hole 5. One end of the rotating rod 6 is rotatably connected to the top of the fixed clamp 44, so that when the rotating rod 6 moves to one side, it drives the fixed clamp 44 to move to one side.

[0036] The fixing groove 7 is opened inside the operating table 1 and is used to limit the rotation frame 4 after the fixing pin 8 enters into one of the multiple fixing holes 9. The multiple fixing holes 9 are used to limit the rotation frame 4 in conjunction with the fixing pin 8 after the rotation frame 4 rotates to the appropriate position.

[0037] The moving mechanism 2 includes a moving groove 21, a moving block 22 is slidably connected inside the moving groove 21, and a telescopic member 23 is fixedly installed on one side of the moving block 22.

[0038] The movable slot 21 is opened inside the operating table 1. One end of the telescopic member 23 is fixedly installed on one end of the inner wall of the movable slot 21, and the other end is fixedly installed on one end of the movable block 22. The telescopic member 23 can be a hydraulic rod or a cylinder, which is used to push the movable block 22 to one side inside the movable slot 21 after starting, thereby driving the drilling mechanism 3 to move to one side.

[0039] The limiting mechanism 10 includes an extension 101, and a limiting clamp 102 is fixedly installed at one end of the extension 101.

[0040] One end of the extension 101 is fixedly installed on the surface of the operating table 1. The extension 101 is a hydraulic rod. Multiple limit clamps 102 are fixedly connected inside the surface of the rotating frame 4. One end of the extension 101 is also fixedly installed with a limit clamp 102. When the extension 101 extends to one side, it drives the limit clamp 102 to move downward and merge with the limit clamp 102 on the rotating frame 4 to limit the steering knuckle and increase the stability during drilling.

[0041] A protective pad 11 is fixedly connected to the surface of the fixing frame 42. The protective pad 11 is made of rubber.

[0042] The protective pad 11 is used to increase the friction between the fixed bracket 42 and the steering knuckle, thereby increasing the fixing effect and directly protecting the steering knuckle and the fixed bracket 42.

[0043] A return spring 12 is provided at one end of the fixing pin 8 and inside the fixing groove 7. A baffle 13 is fixedly connected to the top of the fixing pin 8, and a handle 14 is fixedly connected to the top of the baffle 13.

[0044] The baffle 13 is used to prevent debris from entering the interior of the fixing groove 7, and the handle 14 is used to move the baffle 13 and the fixing pin 8 to one side when moving to one side.

[0045] The reset spring 12 is used so that after the fixing pin 8 is released, the fixing pin 8 can automatically move to one side inside the fixing groove 7 to reset.

[0046] The working principle of the automotive steering knuckle precision machining production line provided by this utility model is as follows:

[0047] In use, after the steering knuckle is placed inside the fixed bracket 42, the two rotating rods 6 are rotated to one side, thereby moving downward inside the two rotating holes 5. When the two rotating rods 6 move downward, they drive the two fixed clamps 44 to move to the appropriate position inside the two fixed grooves 7, thereby fixing the steering knuckle.

[0048] After drilling a steering knuckle, the fixing pin 8 is pulled to one side, and then moved to a suitable position inside the fixing groove 7 and separated from the fixing hole 9. The rotating frame 4 is then rotated to one side, and the next steering knuckle is rotated to a suitable position. The fixing pin 8 is then moved to one side and reset inside the fixing groove 7, so that the fixing pin 8 enters the fixing hole 9 and limits the rotation frame 4.

[0049] This utility model provides a production line for precision machining of automotive steering knuckles. By placing the steering knuckle inside the support frame 41 and the fixed frame 42, and by using the rotating rod 6 in conjunction with the rotating hole 5 and the sliding groove 43 to move the fixed clamp 44 downward to process the steering knuckle, the rotating frame 4 can be rotated to one side to quickly replace the steering knuckle. The steering knuckle can be installed inside the rotating frame 4, so that while drilling a hole in one steering knuckle, another steering knuckle can be replaced, increasing work efficiency.

[0050] Second Embodiment

[0051] Please refer to the following: Figure 5 and Figure 6 Based on the first embodiment of this application, which provides a precision machining production line for automotive steering knuckles, the second embodiment of this application proposes another precision machining production line for automotive steering knuckles. The second embodiment is merely a preferred embodiment of the first embodiment, and the implementation of the second embodiment will not affect the separate implementation of the first embodiment.

[0052] Specifically, the difference in the second embodiment of this application regarding the automotive steering knuckle precision machining production line is that, in the automotive steering knuckle precision machining production line, the fixed frame 42 has a sliding hole 15 inside, a sliding rod 16 is slidably connected inside the sliding hole 15, and a movable frame 17 is fixedly connected to one end of the sliding rod 16.

[0053] Each of the multiple fixed frames 42 has a sliding hole 15 inside, and each of the multiple sliding holes 15 has a sliding rod 16 slidably connected inside. The multiple sliding rods 16 are fixedly connected to the two ends of the bottom of the multiple movable frames 17 in pairs.

[0054] The top of the movable frame 17 is rotatably connected to a rotating rod 19, and a positioning frame 18 is threadedly connected to the surface of the rotating rod 19.

[0055] One side of the positioning frame 18 is fixedly connected to the surface of the rotating frame 4.

[0056] The rotating rod 19 is a threaded rod, and the positioning frame 18 has a threaded hole inside that is adapted to the rotating rod 19, so that when the rotating rod 19 rotates to one side, it moves to one side inside the positioning frame 18.

[0057] The working principle of this utility model is as follows:

[0058] In use, by rotating the rotating rod 19 to one side, it moves downward inside the positioning frame 18. When the positioning frame 18 moves downward, it drives the moving frame 17 connected to the two sliding rods 16 to move to one side inside the two sliding holes 15, thereby pushing the two fixed clamps 44 to move downward simultaneously.

[0059] Reversing the rotation rod 19 will cause the movable frame 17 to move upwards, driving the two sliding rods 16 connected to the fixed clamp 4.

[0060] This utility model provides a production line for precision machining of automotive steering knuckles. By rotating the rotating rod 19, the moving frame 17 drives the two sliding rods 16 connected to the two fixed clamps 44 to move downwards, thereby facilitating the quick and easy installation and removal of steering knuckles.

[0061] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
