[0030] Reference Figure 1-5 ,

[0031] A vacuum adsorption positioning fixture for a sliding seat 5 includes: a positioning base 1, a positioning side plate 2, a connecting member 3, and a pneumatic structure. The pneumatic structure utilizes existing technology and will not be described in detail. The positioning base 1 forms a pneumatic channel 13 and an adsorption port 11 communicating with the pneumatic channel 13. The pneumatic structure is connected to the pneumatic channel 13. The sliding seat 5 is placed on the positioning base 1, and the sliding seat 5 blocks the adsorption port 11. Therefore, when the pneumatic structure draws air from the pneumatic channel 13, the pneumatic channel 13 is at least under negative pressure, or at least under vacuum, preferably under negative pressure, thus adsorbing the sliding seat 5 onto the positioning base. The positioning side plate 2 abuts against the side of the sliding seat 5, and the connecting member 3 connects the positioning side plate 2 to the positioning base 1. The positioning side plate 2 is used to limit the sliding seat 5, so that after the sliding seat 5 is placed on the positioning seat, the position of the sliding seat 5 is restricted, so that it can be better attracted by the pneumatic structure to a suitable position, thereby improving the positioning accuracy and positioning speed.

[0032] Specifically, a groove 12 is formed on the positioning base 1, and the positioning side plate 2 is embedded in the groove 12. This makes it easier to install the positioning side plate 2 into the groove 12.

[0033] Specifically, a sealing strip 4 is provided at the adsorption port 11, and the sealing strip 4 is completely fitted to the adsorption port 11. The sealing strip 4 is used to improve the sealing effect between the adsorption port 11 and the sliding seat 5, thereby improving the stability of adsorption.

[0034] Specifically, multiple adsorption ports 11 and multiple sealing strips 4 are provided. Multiple positions for adsorption of the sliding seat 5 improve the stability of the adsorption and fixation.

[0035] Specifically, multiple blind grooves 51 are formed on the bottom surface of the sliding seat 5. When the sliding seat 5 is placed on the positioning base 1, the suction port 11 aligns with the blind grooves 51. The blind grooves 51 on the bottom surface of the sliding seat 5 are designed to reduce weight. Multiple holes are also formed on the bottom surface of the sliding seat. These holes are used for bolt installation of the sliding seat 5 during actual use. The suction port 11 aligns with the blind grooves 51 but not with the holes, allowing for better suction of the sliding seat 5.

[0036] Specifically, multiple pneumatic channels 13 are provided, with two pneumatic channels 13 located on the first side of the positioning base 1 and another pneumatic channel 13 located on the second side of the positioning base 1; the first side and the second side are adjacent; the multiple pneumatic channels 13 are interconnected. The two pneumatic channels 13 located on the first side are parallel to each other; the pneumatic channel 13 located on the second side is perpendicular to the two pneumatic channels 13 located on the first side. The negative pressure of the multiple pneumatic channels 13 is used to make the suction port 11 suck up the sliding seat 5. The multiple pneumatic channels 13 are all in conjunction with pneumatic structures, or multiple pneumatic structures are provided, which helps to improve the effect of the negative pressure of the pneumatic channels 13.

[0037] Specifically, the connector 3 includes: a first fixing block 31, a second fixing block 32, and an insert block 33; the first fixing block 31 is connected to the positioning base 1, and the second fixing block 32 is connected to the positioning side plate 2; a first slot is formed on the first fixing block 31, and a second slot is formed on the second positioning block, and the insert tube is inserted into the first slot and the second slot; the insert block 33 is at least partially inclined. The opening direction of the first slot is vertically downward, and the opening direction of the second slot is inclined downward; both the first slot and the second slot are T-shaped slots, and the insert block 33 has an insertion part for insertion into the first slot and the second slot; the insertion part matches the first slot and the second slot. A through hole is opened in the middle of the insert block 33, and a bolt is used to pass through the insert block 33 and press the insert block 33 from above, so that the insert block 33 will press the second fixing block 32 downward, so that the second fixing block 32 will push the positioning side plate 2, so that the positioning side plate 2 abuts against the groove 12, and the positioning side plate 2 provides a better limiting function for the sliding seat 5 from the side. The bolt is threadedly connected to the positioning base 1.

[0038] More specifically, an installation groove is formed on the edge of the adsorption port 11, and the sealing strip 4 is embedded into the installation groove for installation. The sealing strip 4 includes a first sealing part, a second sealing part, a third sealing part, a first connecting part, and a second connecting part; the first connecting part connects the first sealing part and the second sealing part, and the second connecting part connects the second sealing part and the third sealing part. The cross-sectional area of ​​the first connecting part and the second connecting part is smaller than the cross-sectional area of ​​the first sealing part, the second sealing part, and the third sealing part, thereby facilitating the formation of a multi-layer seal and improving the sealing effect. The sealing strip 4 also includes an insert, which is embedded in the installation groove. The first sealing part is connected to the insert.
