That is, the mounting end 201 includes a spherical joint 2011, and the mounting hole 101 is provided with a spherical cavity 102 therein, and the spherical joint 2011 is clamped in the spherical cavity 102. The spherical joint 2011 can rotate in the spherical cavity 102, so that the supporting column 2 can realize a corresponding rotating function, a user can conveniently move the part clamped by the clamping tool, and the assembly efficiency is improved.
Wherein, support end 202 includes: a curved boss 2021 and a positioning block 2022. The positioning block 2022 is fixedly disposed on the curved surface boss 2021, and the curved surface boss 2021 is used for supporting the component to be processed. It should be noted that the curved boss 2021 is matched with the structure of the component to be clamped. As is well known, some of the parts to be clamped have mounting tooling holes, and for this part of the product, the clamping tool provides curved bosses 2021 that match such tooling holes. Therefore, the curved surface boss 2021 is used for providing a support for the positioning block 2022, and for providing a supporting force and a better positioning function for a product to be clamped when the mounting hole 101 is matched with the curved surface boss 2021. In addition, the positioning block 2022 serves to provide a pressing force on the surface of the product to be clamped, and serves to replace the curved boss 2021 to perform a basic positioning function and a supporting function when positioning is required.
Wherein, the jacking column 2 is coaxially provided with a first blind ventilation hole 203. The first blind ventilation hole 203 is open at the end face of the mounting end 201, in order to communicate with the vacuum tube 4 through the blind ventilation hole. In addition, the positioning block 2022 is further provided with an air inlet 2023 perpendicular to the axis of the supporting column 2, and the air inlet 2023 is communicated with the first blind ventilation hole 203. The purpose of the communication between the air inlet 2023 and the first blind ventilation hole 203 is to transmit the negative pressure generated by the vacuum tube 4 to the air inlet 2023.
Wherein, the suction cover 3 is disposed at the supporting end 202, as shown in fig. 1 and fig. 3, the suction cover 3 is used for clamping the component to be processed.

The negative pressure machine 5 can generate negative pressure, the negative pressure is transmitted to the mounting hole 101 provided with the jacking column 2 through the vacuum tube 4, then the negative pressure sequentially passes through the first ventilation blind hole 203 and the air inlet hole 2023, a negative pressure area is formed in the adsorption cover 3, when the adsorption cover 3 and the surface of a product to be processed form a closed space, the closed space can generate negative pressure, and the product to be processed is adsorbed on the adsorption cover 3 due to the existence of atmospheric pressure, so that the adsorption force is formed. Optionally, in order to adjust the pressure inside the vacuum tube 4, the clamping tool may further add an adjusting valve 10, as shown in fig. 1, the adjusting valve 10 is disposed at the mounting hole 101 and is in communication with the vacuum tube 4. One possible regulating valve 10 is a throttle valve.
Optionally, as shown in fig. 3, the jacking tool for machining further includes an auxiliary ring, and the auxiliary ring 7 is clamped in a positioning step provided on the suction cover 3. The purpose of additionally arranging the auxiliary ring 7 is to replace the auxiliary ring 7 according to different product types by additionally arranging the auxiliary ring 7, so that the application range of the jacking tool is widened. Meanwhile, the auxiliary ring 7 can also improve the adsorption effect of the adsorption cover 3, so that the adsorption force is changed, and the product is prevented from being damaged. Alternatively, one possible such auxiliary ring 7 is an elastic auxiliary ring 7. In particular, one such auxiliary ring 7 is an auxiliary ring 7 made of rubber.
Likewise, for products with easily damaged surfaces, the jacking tool may further comprise an elastic pad 8. The elastic pad 8 is attached to a contact part of the positioning block 2022 and the component to be processed, and plays a role in buffering and protecting between the positioning block 2022 and the component to be processed. One possible elastic pad 8 is a rubber elastic pad 8, and the rubber elastic pad 8 is adhered to the top end face of the positioning block 2022 by glue.
Optionally, in order to avoid the occurrence of the phenomenon that the product is too heavy or the absorption cover 3 is too large due to too large negative pressure, so that the product falls off and is damaged by being poked by the positioning block 2022, the jacking tool further comprises a protection clamping block 9. As shown in fig. 1, the protective latch 9 is disposed on the supporting column 2 and below the suction cover 3. One possible method for securing the protective latch 9 to the post 2 is by welding.
Optionally, in order to limit and adjust the angle of the jacking tool, one possible limiting and adjusting manner is: a limiting ring 6 with a U-shaped notch is arranged on the top supporting column 2, and the limiting ring 6 is arranged at the mounting hole 101. As shown in fig. 1 and 4, the spacing ring 6 can be a plurality of, and the thickness of the spacing ring 6 can be different, so that the spacing ring 6 is clamped at the position shown in fig. 1, the rotation range of the supporting column 2 is limited, the phenomenon that the swing angle is too large, the product is damaged, and the convenience of the user in use is improved.
Through the above, it can be easily found that, in this embodiment, the jacking tool for machining, on the one hand, according to the negative pressure principle, the adsorption of the product to be machined is realized by using the adsorption cover 3, and on the other hand, through the mounting end 201, especially by using the ball joint 2011, the jacking tool can be conveniently fixed on the substrate 1, compared with the existing clamping mode which is fixed and difficult to move, the flexibility of the jacking tool is improved, meanwhile, the supporting and positioning of the product to be machined are realized through the jacking column 2, so that the jacking tool can deal with the product to be machined with various surface structures. In a word, this top of machining holds instrument and is convenient for the user to remove and operate, avoids treating the damage of processing product surface, improves the qualification rate of product, simultaneously, still has application scope wide, simple structure, maintains the aspect, the advantage of being convenient for operate.
