[0029] The following disclosure provides many different implementation methods or examples for different solutions to implement this utility model.

[0030] See attached document Figure 1 To be continued Figure 6 As shown, a steering knuckle clamp includes a bed 1, a clamp body 2, a clamping device, a top clamping device 3, and a clamping assembly. The bed 1 is provided with a housing 7, and a pad 8 is provided between the housing 7 and the upper end face of the bed 1.

[0031] In one embodiment of this utility model, multiple limiting grooves 11 are provided parallel to the length direction of the bed 1 for mounting the two ends of the pad 8. The cross-section of the limiting groove 11 is convex, so that the pad 8 and the bed 1 can be fixed by inserting one end of the bolt into the limiting groove 11 and tightening the other end.

[0032] In one embodiment of this utility model, the clamp body 2 includes a mounting plate 21 disposed perpendicular to the upper end face of the bed 1 and a pressing device disposed on the outer side of the mounting plate 21. The mounting plate 21 is fixed to the side of the housing 7, so the pressing device is also located on the side that is convenient for workers to operate.

[0033] In one embodiment of this utility model, the clamping device includes three first hydraulic cylinders 22 with their output ends perpendicular to the mounting plate 21, pressure rods 23 respectively provided at the output ends of each first hydraulic cylinder 22, and brackets 25 provided at the top of each first hydraulic cylinder 22. One end of the bracket 25 is fixedly connected to the first hydraulic cylinder 22, and the other end of the bracket 25 is hinged to the corresponding pressure rod 23. A gap is provided between the mounting plate 21 and the side of the bed 1 for the installation of the first hydraulic cylinders 22. The three first hydraulic cylinders 22 are respectively set at the corresponding ends of the steering knuckle, so that the first hydraulic cylinders 22 can push the pressure rods 23 to fix the whole, so as to facilitate subsequent processing operations.

[0034] In one embodiment of this utility model, one end of the pressure rod 23 is hinged to the output end of the corresponding first hydraulic cylinder 22, and the other end of the pressure rod 23 is provided with a pressure surface. The hinge point between the bracket 25 and the pressure rod 23 is the end of the pressure rod 23 away from the pressure surface. The first hydraulic cylinder 22 lifts one end of the pressure rod 23, and the pressure surface at the other end of the pressure rod 23 will press down and connect with the corresponding steering knuckle position.

[0035] In one embodiment of this utility model, the pressure rod 23 can be configured as a Z-shape or a straight line. When the pressure rod 23 is Z-shaped, the swing space of the end of the pressure rod 23 with the pressure surface increases accordingly, which is suitable for pressing down and fixing the part of the steering knuckle with a large thickness. One end of the pressure rod 23 is lifted by the first hydraulic cylinder 22. Under the limitation of the bracket 25, the pressure surface of the other end of the pressure rod 23 will press down and fix the corresponding position of the steering knuckle.

[0036] In one embodiment of this utility model, a positioning post 24 is provided on the outer side of the movable end of each pressure rod 23. The positioning post 24 is set perpendicular to the mounting plate 21. The height of the positioning post 24 is less than the position height of the pressure surface on the corresponding side, so as to ensure that the steering knuckle can be installed between the pressure surface and the mounting plate 21.

[0037] In one embodiment of this utility model, the bracket 25 can be respectively disposed on the long side or the short side of the top of the first hydraulic cylinder 22 to adjust the downward pressing position of the corresponding pressure rod 23. (See attached diagram.) Figure 2 When the bracket 25 is set on the long side of the top of the first hydraulic cylinder 22, and the hinge of the first hydraulic cylinder 22 and the pressure rod 23 are set accordingly, the downward pressing direction of the pressure surface at the other end of the pressure rod 23 is perpendicular to the downward pressing direction of the pressure surface at one end of the pressure rod 23, which is set on the short side of the top of the first hydraulic cylinder 22. Therefore, it can be used to fix steering knuckles of different shapes.

[0038] In one embodiment of this utility model, the clamping device 3 includes a second hydraulic cylinder 31 with its output end perpendicular to the mounting plate 21 and a top member 32 with its output end of the second hydraulic cylinder 31. The mounting plate 21 is provided with a mounting hole for the top member 32 to reciprocate. The mounting hole is located at the center of the clamping device, so that the first hydraulic cylinder 22 can drive one end of the corresponding pressure rod 23 to rise. Under the constraint of the bracket 25, the pressure surface of the other end of the pressure rod 23 will move downward accordingly. In conjunction with the second hydraulic cylinder 31 driving the top member 32 to rise, the upper and lower clamping and fixing of the steering knuckle to be processed can be achieved.

[0039] In one embodiment of this utility model, a parallel clamp is provided on the mounting plate 21, and a boss 4 is provided on the mounting plate 21 that can be fixedly connected to the middle of the parallel clamp. One end of the parallel clamp is provided with a handle 51, and the other end of the parallel clamp is provided with a pressure head 52 made of rubber or nylon material. It has the characteristics of convenient and efficient auxiliary clamping, which can greatly improve efficiency in the process of assembly line operation.

[0040] In one embodiment of the present invention, a set of clamping components is provided on the outside of the parallel clamp. The clamping components include a first pad 61 and a second pad 62 that are fixedly connected to the mounting plate 21 respectively. A first push rod 63 and a second push rod 64 are provided on the adjacent sides of the first pad 61 and the second pad 62. Therefore, an installation space is formed between the first push rod 63 and the second push rod 64 so that the two can be clamped together.

[0041] In one embodiment of this utility model, when fixing the steering knuckle, the position of the steering knuckle to be processed can be initially defined by the positioning pin 24. Then, by controlling the three first hydraulic cylinders 22 to drive one end of the corresponding pressure rod 23 to rise, the pressure surface of the other end of the pressure rod 23 will move downward under the limiting action of the corresponding bracket 25. At the same time, the second hydraulic cylinder 31 drives the top piece 32 to rise, thereby realizing the upper and lower clamping and fixing of the steering knuckle to be processed. Not only can multiple processes be processed in one clamping, further improving the processing efficiency, but the operation is also simple and the processing accuracy is improved.

[0042] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
