Description

Technical Field

[0001] This utility model relates to the field of automotive fixture technology, specifically a fixing fixture for machining automotive steering knuckles. Background Technology

[0002] The steering knuckle is a key component of the automotive steering axle, playing a crucial role in ensuring vehicle stability and steering responsiveness. Its primary function is to transmit and bear the load from the front of the vehicle, while simultaneously supporting and driving the front wheels to rotate around the kingpin, thereby achieving overall vehicle steering control. Due to its critical role in vehicle safety and handling performance, the manufacturing quality of the steering knuckle directly impacts driving safety and the driving experience. During the manufacturing process, to ensure that the dimensional accuracy and geometric tolerances of all parts of the steering knuckle meet design requirements, it must be stably and reliably clamped and fixed to avoid machining errors caused by positional changes during cutting, drilling, or milling processes.

[0003] Because of the complex structure and irregular geometry of automotive steering knuckles, traditional fixing methods often require clamping screws at multiple locations to achieve comprehensive constraint on the workpiece. While this multi-point clamping method provides the necessary positioning and fixation, the large number of clamping points necessitates operators to tighten or loosen each screw individually during each clamping and disassembly process, significantly increasing auxiliary work time. Furthermore, frequent disassembly and assembly operations can easily lead to thread wear, affecting the long-term accuracy of the fixture. In mass production, this inefficient clamping method significantly restricts the improvement of production cycle time and is difficult to adapt to the requirements of modern production lines for high-efficiency and highly flexible processing.

[0004] Based on this, a fixing fixture for machining automotive steering knuckles is now provided, which can eliminate the drawbacks of existing devices. Utility Model Content

[0027] Example 1

[0028] In one embodiment, such as Figures 1-8 As shown, a fixing fixture for machining automotive steering knuckles includes a fixing tube 11, which is mounted on the upper end of a support plate 12. A connecting column 13 is fixedly provided at the bottom end of the support plate 12. The connecting column 13 is rotatably disposed in a rotating hole at the upper end of a worktable 15. The fixing tube 11 is provided with a clamping mechanism for clamping and fixing the automotive steering knuckle body 36. Several limiting rotating rods 26 are rotatably provided on the connecting column 13. Each limiting rotating rod 26 is provided with a guide groove at its upper end. A sliding seat 25 is slidably disposed in each guide groove. Each sliding seat 25 is provided with a positioning column 24 at its upper end. Each limiting rotating rod 26 is provided with an adjustment mechanism for adjusting the working position of the positioning column 24. The clamping mechanism facilitates clamping and fixing automotive steering knuckle bodies 36 of different sizes, and the adjustment mechanism facilitates adjusting the working position of the positioning column 24, thereby enabling rapid positioning of automotive steering knuckle bodies 36 of different sizes.

[0029] The end of the connecting column 13 is fixedly connected to the output end of the motor 14. The motor 14 is installed inside the mounting bracket. The mounting bracket is fixedly installed at the bottom of the workbench 15. The bottom of the workbench 15 is provided with several support legs. When it is needed to perform multi-angle machining on the automobile steering knuckle body 36, the motor 14 can be started. The output end of the motor 14 drives the connecting column 13 to rotate. The connecting column 13 drives the bearing plate 12 and the fixing tube 11 to rotate, which in turn drives the automobile steering knuckle body 36 to rotate.

[0030] The clamping mechanism includes clamping rods 16. A plurality of clamping rods 16 are arranged in an array on the outer side of the fixed tube 11. Each clamping rod 16 has a connecting rod 17 hinged to one side, and the other end of each connecting rod 17 is hinged to a hinge seat 18. A plurality of guide slide rods are slidably arranged on the hinge seat 18, and each guide slide rod is fixedly disposed inside the fixed tube 11. A threaded hole is provided in the middle of the hinge seat 18, and a first threaded rod 19 is fitted into the threaded hole. The first threaded rod 19 is rotatably disposed inside the fixed tube 11. A torsion block 20 is fixedly disposed at one end of the first threaded rod 19. Each clamping rod 16 has a fixed end... The limiting slide rod is slidably disposed in the sliding hole at the bottom end of the fixed tube 11. In use, when the middle part of the car steering knuckle body 36 is through the hole and sleeved on the fixed tube 11, and the car steering knuckle body 36 is placed on the upper end of the bearing plate 12, the torsion block 20 is rotated. The torsion block 20 drives the first threaded rod 19 to rotate. Under the action of the thread, the hinge seat 18 moves along the axis of the first threaded rod 19. At the same time, the hinge seat 18 drives several clamping rods 16 to slide through several connecting rods 17. When one side of the clamping rod 16 is in close contact with the middle hole of the car steering knuckle body 36, the car steering knuckle body 36 can be clamped and fixed.

[0031] Each clamping rod 16 is slidably provided with a limiting block 21. A first fixing tube is installed on one side of each limiting block 21. Both the limiting block 21 and the end of the fixing tube have through holes. A first stop plate 22 is slidably provided inside each first fixing tube. The first stop plate 22 is rotatably mounted on one end of a first screw 23. Threaded holes are provided at the corresponding positions of the first fixing tube and the first screw 23. In use, according to the height of the car steering knuckle body 36, the bottom end of the limiting block 21 is made to be in close contact with the upper end of the car steering knuckle body 36. Then, the first screw 23 is rotated, and under the action of the thread, the first stop plate 22 is made to be in close contact with one side of the clamping rod 16, thereby fixing the limiting block 21. When the clamping rod 16 clamps the car steering knuckle body 36, the limiting block 21 can limit the car steering knuckle body 36.

[0032] The adjusting mechanism includes a second threaded rod 27 fitted into the threaded hole in the middle of the sliding seat 25. The second threaded rod 27 is rotatably disposed inside the limiting rod 26. A stop post 28 is fixedly disposed at one end of the second threaded rod 27. A second stop plate 29 is fitted onto the stop post 28. The second stop plate 29 is rotatably disposed at one end of a second screw 30. The second screw 30 is fitted into the threaded hole at the end of the second fixing tube. The second fixing tube is fixedly disposed at the upper end of the limiting rod 26. In use, before fixing the steering knuckle body 36, the position of the through hole on the steering knuckle body 36 is adjusted to ensure that... The limiting rod 26 rotates on the connecting column 13. Then, according to the position of the through hole on the steering knuckle body 36, the second threaded rod 27 is rotated. Under the action of the thread, the sliding seat 25 drives the positioning column 24 to slide in the guide groove at the upper end of the limiting rod 26. After the adjustment is completed, the second screw 30 is rotated. Under the action of the thread, the second stop plate 29 is pressed tightly against the stop column 28, thereby fixing the second threaded rod 27. Before fixing the steering knuckle body 36, the positioning column 24 is inserted into the through hole on the steering knuckle body 36, thereby quickly positioning the steering knuckle body 36.

[0033] Each limiting rod 26 has a limiting tube fixedly installed at its bottom end. A push rod 32 is slidably installed inside each limiting tube. A sliding frame 33 is fixedly installed at one end of each push rod 32, and the sliding frame 33 slides on the limiting rod 26. A limiting plate 31 is fixedly installed at the other end of each push rod 32. The limiting plate 31 is arc-shaped. Tension springs 34 are symmetrically installed on one side of each sliding frame 33. The other end of each tension spring 34 is fixedly connected to one side of a fixed plate. The fixed plates are all fixedly installed at the bottom end of the limiting rod 26. A top rod 35 is fixedly installed at the upper end of each second stop plate 29. One end of the push rod 35 is tightly attached to one side of the sliding frame 33. In use, when it is necessary to fix the working position of the limiting rotating rod 26, the push rod 32 is pushed to slide by the sliding frame 33, so that the limiting plate 31 is tightly attached to the connecting column 13, thereby fixing the limiting rotating rod 26. Then, the second screw 30 is rotated to drive the second stop plate 29 to slide. The second stop plate 29 drives the push rod 35 to move, so that one end of the push rod 35 is tightly attached to one side of the sliding frame 33, thereby fixing the push rod 32. With the cooperation of the limiting plate 31 and the connecting column 13, the limiting rotating rod 26 is fixed.

[0034] Example 2

[0035] The difference from Embodiment 1 is that: the bottom end of each positioning post 24 is provided with a stud, and the upper end of the sliding seat 25 is provided with a threaded groove. In use, it is convenient to replace positioning posts 24 of different sizes, thereby facilitating the positioning of automotive steering knuckle bodies 36 of different sizes.

[0036] The above embodiment discloses a fixing fixture for machining automotive steering knuckles. Before fixing the automotive steering knuckle body 36, the limiting rod 26 rotates on the connecting post 13 according to the position of the through hole on the automotive steering knuckle body 36. Then, according to the position of the through hole on the automotive steering knuckle body 36, the second threaded rod 27 is rotated. Under the action of the thread, the sliding seat 25 drives the positioning post 24 to slide within the guide groove at the upper end of the limiting rod 26. After adjustment, the sliding frame 33 pushes the push rod 32 to slide, causing the limiting plate 31 to be tightly attached to the connecting post 13, thereby fixing the limiting rod 26. Then, the second screw 30 is rotated, and under the action of the thread, the second stop plate... 29 is in close contact with the stop post 28, thereby fixing the second threaded rod 27, so that before fixing the car steering knuckle body 36, the positioning post 24 is inserted into the through hole on the car steering knuckle body 36, thereby quickly positioning the car steering knuckle body 36. At the same time, according to the height of the car steering knuckle body 36, the bottom end of the limiting block 21 is in close contact with the upper end of the car steering knuckle body 36. Then, the first screw 23 is rotated, and under the action of the thread, the first stop plate 22 is in close contact with one side of the clamping rod 16, thereby fixing the limiting block 21, so that when the clamping rod 16 clamps the car steering knuckle body 36, the limiting block 21 can limit the car steering knuckle body 36.

[0037] Subsequently, the car steering knuckle body 36 is perforated in the middle and fitted onto the fixing tube 11. After the car steering knuckle body 36 is placed on the upper end of the bearing plate 12, the torsion block 20 is rotated. The torsion block 20 drives the first threaded rod 19 to rotate. Under the action of the thread, the hinge seat 18 moves along the axis of the first threaded rod 19. At the same time, the hinge seat 18 drives several clamping rods 16 to slide through several connecting rods 17. When one side of the clamping rod 16 is in close contact with the perforation in the middle of the car steering knuckle body 36, the car steering knuckle body 36 can be clamped and fixed.

[0038] When the steering knuckle body 36 of the car needs to be processed at multiple angles, the motor 14 can be started. The output end of the motor 14 drives the connecting column 13 to rotate, and the connecting column 13 drives the bearing plate 12 and the fixing tube 11 to rotate, which in turn drives the steering knuckle body 36 of the car to rotate.

[0039] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
