[0040] When the length of the first clamping plate 203 is less than the length of the second clamping plate 204, the first through hole 201 is provided on the first clamping plate 203 or the second clamping plate 204, and the second through hole 202 is provided on the second clamping plate 204.

[0043] In some embodiments of the present application, an interchangeable component 20 is provided and placed on a positioning fixture 10. Through holes are provided on at least two sides of the interchangeable component 20, so that the positioning member 102 and the fixing pin 1011 in the positioning fixture 10 can be inserted into the corresponding through holes respectively. The fixing pin 1011 and the positioning member 102 cooperate to press the interchangeable component 20 to implement the fixing operation of the interchangeable component 20, and then press the product to be processed placed in the interchangeable component 20, which can avoid the offset of the interchangeable component 20 and / or the product to be processed during the processing, improve the alignment rate of the processing tool and the product to be processed in the interchangeable component 20, and reduce the possibility of damage to the processing tool and the like.

[0044] It is worth noting that in some embodiments, the interchangeable component 20 includes only a plurality of first through holes 201, so that the fixing pins 1011 provided on the bottom plate 101 are inserted into the corresponding first through holes 201. At this time, the fixing operation of the interchangeable component 20 can be achieved by limiting the distance between the positioning member 102 and the interchangeable component 20. That is, there is a preset distance between the positioning member 102 and the side of the interchangeable component 20 away from the bottom plate 101. With the cooperation of the fixing pins 1011, even if the positioning fixture 10 moves, rotates, etc., the interchangeable component 20 will not fall off. However, before processing the product to be processed placed in the interchangeable component 20, it is necessary to realign the product to be processed to avoid damaging the tools such as the cutting tool used for processing and ensure the product yield.

[0048] In some embodiments, each positioning member 102 is provided with a first groove, and the movable rod 1032 is inserted into the corresponding first groove and abuts against the positioning member 102.

For example, the positioning fixture 10 includes two drive components 103, and the drive bodies 1031 in the two drive components 103 are placed in opposite positions, so that the air inlet holes 301 and the air outlet holes 302 on the two drive components 103 are located on two opposite sides, and then the air inlet holes 301 of the two drive components 103 are connected to the air inlet holes 301 by using the first air duct, and the air outlet holes 302 of the two drive components 103 are connected to the air outlet holes 302 by using the second air duct. The first air duct and the second air duct can be hidden under the bottom plate 101.
