[0033] The first floating adjustment component 4 adjusts the position of the workpiece in the X direction. Since the first floating adjustment component 4 is elastically connected to the first floating plate 1, the first floating plate 1 can adaptively compensate for centering in the X direction. The second floating adjustment component 5 adjusts the position of the workpiece in the Y direction. The second floating adjustment component 5 is elastically connected to the second floating plate 2, so that the second floating plate 2 can adaptively compensate for centering in the Y direction, thereby ensuring the positioning accuracy of the workpiece for subsequent assembly. In this way, even if the processing accuracy of the workpiece itself is not enough, the assembly can be completed, the operation is convenient, the production efficiency is high, and the positioning effect is good.

[0035] like Figure 1-Figure 6As shown, in some other specific embodiments, a connecting block 101 is detachably provided on the first floating plate 1, the first floating adjustment component 4 includes a first fixing portion 401, a second fixing portion 402, a first floating block 403 provided between the first fixing portion 401 and the second fixing portion 402, and a first size adjuster 404 inserted on the first fixing portion 401, one end of the first size adjuster 404 abuts against the first floating block 403, a first reset elastic component is provided on the second fixing portion 402, one end of the first reset elastic component abuts against the first floating block 403, a first floating elastic component and a second floating elastic component are symmetrically provided on both sides of the first floating block 403, one end of the first floating elastic component abuts against the connecting block 101, and one end of the second floating elastic component abuts against the connecting block 101, and further, a second floating groove 4031 is provided on the upper end of the first floating block 403 , the connecting block 101 is arranged in the second floating groove 4031, the first reset elastic component includes a first limiting portion 7 inserted on the second fixed portion 402, and a first reset spring 8 mounted on the first limiting portion 7, the first limiting portion 7 is abutted against the first floating block 403, one end of the first reset spring 8 is abutted against the second fixed portion 402, and the other end thereof is abutted against the first floating block 403, the first floating elastic component includes a second limiting portion 9, and a first floating spring 10 mounted on the second limiting portion 9, the second floating elastic component includes a third limiting portion 11, and a second floating spring 12 mounted on the third limiting portion 11, the second limiting portion 9 is inserted on one of the groove walls of the second floating groove 4031, the third limiting portion 11 is inserted on the other groove wall of the second floating groove 4031, and the connecting block 101 is located between the second limiting portion 9 and the third limiting portion 11.

Since the first floating spring 10 and the second floating spring 12 are both elastic, the first floating plate 1 will adaptively compensate for the centering. In this way, even if the machining accuracy of the workpiece in the X direction is not enough, causing a small amount of interference, the workpiece can still adaptively compensate for the accuracy error, thereby completing the assembly. When resetting is required, the first size adjuster 404 is operated, and the first resetting spring 8 pushes the first floating block 403 to reset.

Since the third floating spring 16 and the fourth floating spring 18 are both elastic, the second floating plate 2 will adaptively compensate for the centering.
