[0026] In order to more clearly understand the technical means of the utility model and implement it according to the contents of the specification, the specific implementation methods of the utility model are further described in detail below in conjunction with the drawings and embodiments. The following embodiments are used to illustrate the utility model but are not used to limit the scope of the utility model.

[0027] This specific embodiment relates to a clamping mechanism for machining a steering knuckle 400, such as Figure 1 and Figure 3 As shown, the driving end of the mechanical arm is provided with a bracket and the rotary cylinder 500 is installed on the bracket. The driving end of the rotary cylinder 500 is provided with a platform 100, so that the rotary cylinder 500 can drive the platform 100 to rotate. The platform 100 is in the shape of a metal plate. The top surface of the platform 100 is provided with two sets of positioning components 200 that are positioned and matched with the steering knuckle 400, and the two sets of positioning components 200 are arranged in mirror symmetry. Through the mechanical arm, the positioning component 200 will move three-dimensionally in space, and finally the positioning component 200 is positioned and matched with the steering knuckle 400.

[0028] like Figure 1 and Figure 3 As shown, the positioning assembly 200 includes a positioning plate 210 and at least one positioning block 220 fixedly mounted on the top surface of the positioning plate 210 in the vertical direction. Because there are at least two groups of positioning assemblies 200, and each group of positioning assemblies 200 has at least one positioning block 220, there are at least two positioning blocks 220, so that the steering knuckle 400 can be installed in the positioning assembly 200. The cross section of the positioning plate 210 is approximately "Y" shaped. The steering knuckle 400 will eventually be placed on the positioning block 220. In each group of positioning assemblies 200, the positioning blocks 220 are mounted on the top surface of the positioning plate 210 by bolts and are distributed in a triangular shape to improve the stability of the steering knuckle 400 placed on the positioning block 220. The top surface of the positioning block 220 is provided with an embedding groove 221 for placing the steering knuckle 400. The runner on the steering knuckle 400 will be embedded in the embedding groove 221, so as to fix the steering knuckle 400. The embedding groove 221 is provided with an inclined surface that fits the steering knuckle 400. The surface of the steering knuckle 400 will fit on the inclined surface, so that the steering knuckle 400 can be better embedded in the embedding groove 221, thereby further improving the stability of the placement of the steering knuckle 400.

[0029] like Figure 1 and Figure 2As shown, the positioning assembly 200 also includes a plurality of guide rods 230 arranged in the vertical direction. One end of the guide rod 230 is arranged on the bottom surface of the positioning plate 210 and the other end thereof passes through the platform 100. The positioning plate 210 can move up and down in the vertical direction through the guide rod 230. In each group of positioning assemblies 200, the number of the guide rods 230 is four.

[0030] like Figure 1 and Figure 2 As shown, in this specific embodiment, it also includes a cylinder 240 arranged on the platform 100 in the vertical direction, and the top of the cylinder 240 is connected to the positioning plate 210 in the positioning assembly 200 in a one-to-one correspondence to drive the positioning plate 210 to reciprocate in the vertical direction. Each group of positioning assemblies 200 is equipped with a cylinder 240. When the entire positioning assembly 200 is moved to the bottom of the steering knuckle 400 by the robot arm, the cylinder 240 will lift the positioning assembly 200 upward until the positioning block 220 in the positioning assembly 200 contacts the steering knuckle 400, and then the steering knuckle 400 is ejected out of the cavity by the ejector rod in the mold so as to be placed in the positioning block 220. In this way, the success rate of placing the steering knuckle 400 in the positioning block 220 is increased.

[0031] like Figure 1 , Figure 2 , Figure 4 and Figure 5 As shown, the top surface of the platform 100 is also provided with a pressure claw assembly 300 for pressing the steering knuckle 400 that is positioned and matched with the positioning assembly 200. The preferred pressing method of the pressure claw assembly 300 is: pressing the steering knuckle 400 from top to bottom or clamping the steering knuckle 400 from the side. The pressure claw assembly 300 and the positioning assembly 200 operate independently. Each group of pressure claw assemblies 300 includes a driving member 310 whose fixed end is located on the top surface of the platform 100, and the driving member 310 is misaligned with the positioning assembly 200. The driving member 310 is preferably a cylinder. The number of the driving members 310 is two and they are located on both sides of the steering knuckle 400. The driving end of each driving member 310 is rotatably connected with a pressure claw 320 that can press the steering knuckle 400 on the positioning assembly 200 from top to bottom. The pressure claw 320 is used to press the central part of the steering knuckle 400 downwards, and cooperates with the positioning block 220 to fix the steering knuckle 400.

[0032] like Figure 1 and Figure 5As shown, the bottom of the pressing claw 320 is rotatably connected to the driving end of the driving member 310 through a rotating rod; a groove 340 is provided at the bottom of the pressing claw 320 and the rotating rod is inserted into the groove 340, and the rotating rod also passes through the driving end of the driving member 310. During operation, the groove 340 does not interfere with the driving end of the driving member 310. A hinge 330 used as a rotating fulcrum of the pressing claw 320 is also rotatably connected to the outer wall of the driving member 310, and the other end of the hinge 330 is rotatably connected to the middle part of the pressing claw 320. Two groups of through holes are provided on both side surfaces of the pressing claw 320, one group of through holes is used to install the hinge 330, and the hinge 330 is installed on both side surfaces of the pressing claw 320; the other group of through holes is used to install the rotating rod. The pressure claw 320 has two states: when the steering knuckle 400 has not been placed in the positioning block 220, the driving rod of the driving member 310 is in a retracted state, so that the pressure claw 320 is directed upward to facilitate the placement of the steering knuckle 400 in the positioning block 220; when the steering knuckle 400 is placed in the positioning block 220, the driving rod of the driving member 310 is extended, and the pressure claw 320 rotates with the cooperation of the hinge 330, and finally the pressure claw 320 is pressed against the top surface at the center of the steering knuckle 400, and the steering knuckle 400 is fixed with the cooperation of the pressure claw 320 and the positioning block 220, and the steering knuckle 400 can move with the movement of the robotic arm.

[0033] Working principle: After the knuckle 400 is cooled and formed in the mold, the positioning assembly 200 will be moved to the bottom of the mold under the drive of the robot arm. The cylinder 240 pushes the positioning plate 210 to move upward until the positioning block 220 contacts the knuckle 400. The ejector rod in the mold will push the knuckle 400 out of the mold cavity, and the knuckle 400 will fall into the groove 340 of the positioning block 220. Subsequently, the cylinder 240 drives the positioning assembly 200 to move downward, and at the same time, the downward movement of the positioning assembly 200 will drive the knuckle 400 to move downward. Finally, the driving member 310 drives the pressing claw 320 to rotate, and the knuckle 400 is pressed and fixed by the pressing claw 320.

[0034] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. It should be pointed out that a person skilled in the art can make several improvements and modifications without departing from the technical principle of the present invention, and these improvements and modifications should also be regarded as within the protection scope of the present invention.
