[0035] The working principle and use process of the utility model:

[0036] In the initial state, the pin hole of the knuckle with mounting hole to be machined is clamped by the fixed column 14, so that the knuckle to be machined is fixed to the sliding plate 13 close to the fixed plate 12 side;

[0037] The sliding cylinder 15 drives the sliding plate 13 to slide towards the fixed plate 12, until the first clamping part 25 is clamped into the mounting hole of the knuckle to be machined; at the same time, the rotating shaft 27 slides towards the fixed plate 12 together with the sliding plate 13, so that the clamping block 271 on the rotating shaft 27 is clamped into the clamping groove 221 on the rotating screw 22, so that the rotating shaft 27 is connected with the rotating screw 22;

[0038] The rotating motor 26 drives the rotating shaft 27 to rotate, thereby driving the rotating screw 22 threadedly connected with the fixed cylinder 21 to rotate along the axial direction of itself, and then driving the moving cylinder 23 fixed with the rotating screw 22 to slide along the axial direction of the fixed cylinder 21; in the process of the moving cylinder 23 sliding towards the fixed plate 12, the axial angle between the connecting rod 24 and the moving cylinder 23 gradually increases, and the angle between the connecting rod 24 and the first clamping part 25 also gradually increases, so that the first clamping part 25 is completely matched with the inner wall of the mounting hole of the knuckle to be machined, thereby realizing the purpose of fixing the knuckle to be machined;

[0039] Similarly, when the knuckle with a round rod needs to be machined, the fixed column 14 on the sliding plate 13 on the other side of the fixed plate 12 will be inserted into the pin hole on the knuckle; the sliding cylinder 15 drives the sliding plate 13 to slide towards the fixed plate 12, until the round rod of the knuckle to be machined is located between the plurality of second clamping parts 31;

[0040] At this time, the clamping block 271 on the rotating shaft 27 is clamped with the clamping groove 221 on the rotating screw 22; the rotating motor 26 drives the rotating shaft 27 to rotate, thereby driving the rotating screw 22 threadedly connected with the fixed cylinder 21 to rotate along the axial direction of itself, and then driving the moving cylinder 23 fixed with the rotating screw 22 to slide along the axial direction of the fixed cylinder 21; in the process of the moving cylinder 23 sliding away from the fixed plate 12, the axial angle between the connecting rod 24 and the moving cylinder 23 gradually decreases, and the angle between the connecting rod 24 and the first clamping part 25 also gradually decreases, so that the plurality of first clamping parts 25 are close to each other; thereby driving the second clamping part 31 fixedly connected with the first clamping part 25 to slide in the sliding groove 121, so that the round rod of the knuckle to be machined is fixed by the plurality of second clamping parts 31, thereby realizing the purpose of fixing the knuckle to be machined;

[0041] In the process that the plurality of second clamping pieces 31 slide towards the direction of approaching each other to fix the round rod of the knuckle to be processed, the third clamping block 32 connected with the second clamping piece 31 through the reset spring sheet 33 also abuts the round rod of the knuckle to be processed until the round rod of the knuckle is fixed, at which time the reset spring sheet 33 is compressed; in this way, the knuckle to be processed is more stably fixed, thereby ensuring the subsequent processing quality.
