Description

Technical Field

[0001] The utility model relates to the technical field of automobile accessories, in particular to a hydraulic processing fixture for a steering knuckle. Background Art

[0002] The steering knuckle, also known as the "ram's horn," is a critical component in a vehicle's steering axle. It primarily consists of a support journal, flange, fork, and knuckle arm. The knuckle's primary function is to transmit the vehicle's direction of travel and drive the front wheels around the main axis, thereby ensuring steering and stable driving. The knuckle is typically connected to the vehicle body via three bushings and two bolts, and to the brake system via the brake mounting holes in the flange. During machining, the knuckle requires a hydraulic fixture for clamping.

[0003] A search revealed a hydraulic clamp compatible with the processing of multiple steering knuckles with authorization announcement number CN218504326U, stating that "the present invention provides a staggered clamping assembly. The first curved rack plate can be pressed against the upper portion of one side of the outer wall of the steering knuckle, while the second curved rack plate can be pressed against the lower portion of the other side of the steering knuckle. The first curved rack plate and the second curved rack plate form a staggered, extruding, and clamping force, which increases the clamping force. In the future, different types of steering knuckles can be placed and locked. Later maintenance only requires the replacement of the hydraulic cylinder, which is more convenient and reduces the cost of later maintenance and use."

[0004] However, the above solution still has certain shortcomings in actual use. The solution uses a hydraulic cylinder to drive the arc-shaped rack plate to assist in clamping the steering knuckle. However, the steering knuckle cannot be adjusted in angle after being clamped by the arc-shaped rack plate. When different positions of the steering knuckle need to be processed, the steering knuckle needs to be disassembled in advance and then its angle needs to be adjusted before assembly, which greatly reduces the processing efficiency of the steering knuckle.

[0022] See also Figure 1-4 The utility model discloses a hydraulic machining fixture for a steering knuckle, comprising a machining table 1 and a steering knuckle body 5. A turning device 2 and a connecting column 3 are fixedly mounted on the top of the machining table 1. A clamping device 4 is rotatably connected between the turning device 2 and the connecting column 3. The steering knuckle body 5 is located inside the clamping device 4.

[0023] The flipping device 2 includes a placement plate 201, the top of which is rotatably connected to a driving gear 202 and a positioning rack 203 via an external power supply. The top of the driving gear 202 is engaged with a follower gear 204. An annular groove 205 is provided on the front side of the follower gear 204.

[0024] The clamping device 4 includes a rotating platform 401, the front side of which is fixedly connected to the back side of the connecting plate 207. A driving structure 402 and a displacement arc plate 404 are fixedly installed on the top of the rotating platform 401. The movable end of the driving structure 402 is fixedly installed with the displacement arc plate 404. The steering knuckle body 5 is located between the displacement arc plate 404 and the fixed arc plate 403.

[0025] The driving structure 402 includes a driving box 405, the inner wall of which is rotatably connected to a rotating shaft 406 through a built-in power supply, a displacement ring 407 is provided on the surface of the rotating shaft 406, the outer side of the displacement ring 407 is rotatably connected to a hinged rod 408, the other end of the hinged rod 408 is hinged to a displacement plate 409, the other end of the displacement plate 409 extends to the outside of the driving box 405 and is connected to the outside of the displacement arc plate 404.

[0026] By setting up a flipping device 2 and a clamping device 4, the driving structure 402 contained in the clamping device 4 can drive the displacement arc plate 404 to fix the steering knuckle body 5 between the displacement arc plate 404 and the fixed arc plate 403, and then the driving gear 202 contained in the flipping device 2 can drive the follower gear 204 to drive the clamping device 4 to adjust the angle through the connecting plate 207, so that the processing fixture can flip the steering knuckle body 5 in the clamping state, thereby avoiding the need to pre-disassemble the steering knuckle body 5 and then adjust its angle and then assemble it, so that the processing efficiency of the steering knuckle is significantly improved.

[0027] Specifically, the top end of the placement plate 201 is rotatably connected to a positioning rack 203 via an external power source, and the positioning rack 203 is adapted to the driving gear 202 .

[0028] In this embodiment, when it is necessary to position the rotating driving gear 202, the positioning rack 203 is driven to move by an external power supply, causing the positioning rack 203 to gradually engage with the driving gear 202, and then limiting the driving gear 202 so that the driving gear 202 can no longer rotate.

[0029] Specifically, an arc groove connected end to end is opened on the surface of the rotating shaft 406, and an insertion rod is fixedly installed on the inner wall of the displacement ring 407, and the insertion rod extends to the inside of the opening of the arc groove.

[0030] In this embodiment, the opening of the arc-shaped groove connected end to end on the surface of the rotating shaft 406 rotates, and the insertion rod on the inner side of the displacement ring 407 is located on the inner side of the opening of the arc-shaped groove, so that the opening of the arc-shaped groove drives the displacement ring 407 to move in the axial direction through the insertion rod.

[0031] Specifically, two sockets are provided inside the fixed arc plate 403 , and the sockets are adapted to the bifurcated ends of the displacement arc plate 404 .

[0032] In this embodiment, the two sockets can be used to allow the displacement arc plate 404 and the fixed arc plate 403 to be closed to the greatest extent, so that the displacement arc plate 404 and the fixed arc plate 403 can adapt to steering knuckle bodies 5 of different sizes.

[0033] When in use, the steering knuckle body 5 is first placed on the rotating table 401, and then the driving structure 402 is started, so that the built-in power supply inside the driving box 405 drives the rotating shaft 406 to rotate, so that the opening of the arc groove connected end to end opened on the surface of the rotating shaft 406 rotates, and the insertion rod on the inner side of the displacement ring 407 is located inside the opening of the arc groove, so that the opening of the arc groove drives the displacement ring 407 to move in the axial direction through the insertion rod, so that the displacement ring 407 drives the hinge rod 408 to adjust the angle during the movement, so that the other end of the hinge rod 408 drives the displacement arc plate 404 to move through the displacement plate 409, so that the displacement arc plate 404 and the fixed arc plate 403 gradually close and clamp the steering knuckle body 5 therein;

[0034] When the angle of the clamped steering knuckle body 5 needs to be adjusted, the driving gear 202 is driven to rotate by an external power supply, so that the driving gear 202 drives the follower gear 204 to engage and transmit, and the follower gear 204 drives the rotating platform 401 to rotate through the connecting plate 207, so that the angle of the rotating platform 401 is adjusted;

[0035] When the rotated driving gear 202 needs to be positioned, the positioning rack 203 is displaced by an external power supply, causing the positioning rack 203 to gradually engage with the driving gear 202, thereby limiting the driving gear 202 so that the driving gear 202 can no longer rotate.

[0036] To sum up, the hydraulic processing fixture for the steering knuckle is provided with a flipping device 2 and a clamping device 4. The driving structure 402 contained in the clamping device 4 can drive the displacement arc plate 404 to fix the steering knuckle body 5 between the displacement arc plate 404 and the fixed arc plate 403. The driving gear 202 contained in the flipping device 2 can drive the follower gear 204 to drive the clamping device 4 to adjust the angle through the connecting plate 207, so that the processing fixture can flip the steering knuckle body 5 in the clamping state, thereby avoiding the need to pre-disassemble the steering knuckle body 5 and then adjust its angle and then assemble it, thereby significantly improving the processing efficiency of the steering knuckle.
