The spring assembly 30 is disposed between the clamp member 22 and the carrier plate 10. When the workpiece is placed on the object carrying plate 10, the clamping member 22 is driven by the driving element 21 to fix the workpiece to the object carrying plate 10, and the elastic component 30 elastically supports the workpiece, so as to assist in positioning the workpiece. On the basis that the clamping piece 22 fixes the workpiece, the elastic assembly 30 also elastically positions the workpiece, so that the workpiece can be prevented from being deformed during machining, the workpiece can be guaranteed to have a stable size after machining, and the precision of the easily deformed product after machining is improved.

The clamping member 40 includes a first clamping portion 41 and a second clamping portion, wherein the first clamping portion 41 is disposed on the object plate 10, and the second clamping portion is disposed on the clamping member 22 corresponding to the first clamping portion 41. When the clamp 22 moves toward the loading plate 10, the clamp 22 and the loading plate 10 clamp the workpiece by the engagement of the first clamping portion 41 and the second clamping portion. According to the principle that three points which are not in the same straight line determine a plane, at least three clamping pieces 40 can stably clamp the workpiece, and other parts of the workpiece are not clamped, so that the workpiece can be prevented from being deformed due to clamping, the other parts of the workpiece are ensured to be in a free state, and the workpiece is convenient to process.

The elastic member 30 is provided to the clamping member 22. The processing fixture further comprises at least one elastic bearing component 50. The elastic bearing component 50 is disposed on the loading plate 10 corresponding to the elastic component 30, so that when the workpiece is clamped, the elastic bearing component 50 is elastically supported on two sides of the workpiece corresponding to the elastic component 30. The loading plate 10 is in contact with the workpiece through the elastic bearing assembly 50, so that both sides of the workpiece are elastically supported, and the positioning of the workpiece is better assisted.

When the external force is smaller than the elastic force of the elastic member 32, the workpiece can be stably clamped to the processing jig.

It is to be noted that the pressing member 31 comes into contact with the workpiece when the workpiece is held by the clamping member 22 and the carrier plate 10. If the elastic member 32 is not in a compressed state, the workpiece is not subjected to the elastic pressing force transmitted from the pressing member 31, so that the workpiece is easily deformed. Here, the elastic element 32 can be changed in its degree of compression by the positioning element 33, so that the workpiece is subjected to different levels of elastic pressing force. In a case where the distance from the positioning member 33 to the clamping member 22 is shortened, the elastic member 32 is in a compressed state, and the elastic member 32 elastically fixes the pressing member 31 in the stepped hole. Therefore, when the clamping member 22 brings the pressing member 31 into contact with the workpiece, the elastic member 32 will continue to be compressed after the force of the workpiece pushing the pressing member 31 exceeds the elastic force of the elastic member 32, so that the pressing member 31 will not move randomly, and the workpiece can be stably clamped.

The elastic members 32 are compressed to different degrees so that the pressing members 31 can receive different elastic pressing forces, and the pressing members 31 support the workpiece with different elastic forces.
