[0012] By adopting the above technical solution, during use, the position of the sliding sleeve is adjusted through the vent hole 1 and the vent hole 2, so that the position is more accurate.

[0013] The present application also discloses a position adjustment method, including the above-mentioned position adjustment tool, and also includes the following steps: a sleeve step, sleeve the sliding sleeve on the positioning rod, an installation step, install one positioning rod on the base, and the other positioning rod on the mobile device, an adjustment step, the mobile device adjusts the position of the product, and a sliding step, moving the sliding sleeve so that it can move freely up and down. If it cannot move freely up and down, repeating the adjustment step and this step.

[0014] In a preferred example, the present application can be further configured as follows: in the sliding step, vent hole 2 discharges gas to make the sliding sleeve suspended, and then vent hole 1 discharges gas to correct the position of the sliding sleeve. After the correction is completed, vent hole 1 stops discharging gas, and vent hole 2 increases the outlet pressure to move the sliding sleeve. BRIEF DESCRIPTION OF THE DRAWINGS

[0017] The present application is further described in detail below in conjunction with the accompanying drawings.

[0018] Reference Figure 1, is a position adjustment tool disclosed in the present application, comprising a positioning rod 1 and a sliding sleeve 2, the positioning rod 1 comprising a positioning section 12 and a connecting section 11, the connecting section 11 and the positioning section 12 are arranged concentrically, the diameter of the connecting section 11 is larger than the diameter of the positioning section 12, the connecting section 11 and the positioning section 12 form a sliding groove 13, the inner diameter of the sliding sleeve 2 is greater than or equal to the diameter of the positioning section 12, and smaller than the diameter of the connecting section 11, and the diameter difference between the inner diameter of the sliding sleeve 2 and the outer diameter of the positioning section 12 can be set according to the actual error value. There are two positioning rods 1, one is installed on the base, and the other is installed on the mobile device. When one positioning rod 1 is installed on the base and the other positioning rod 1 is installed on the mobile device, the sliding grooves 13 are arranged relative to each other. In this embodiment, the mobile device is arranged above the base. The sliding sleeve 2 is located on the positioning rod 1 installed on the base. Therefore, when the position of the mobile device changes, the two positioning rods 1 are relative to each other. In this embodiment, the moving device can be a structure that can realize the movement of an object, such as a manipulator, a moving module, and a trolley driven by a driving unit such as a cylinder or a hydraulic cylinder. The positioning rod 1 is installed on a movable structure of the moving device, such as the trolley mentioned above. In this embodiment, a plurality of vent holes 1 31 are provided on the circumference of the positioning section 12 of any positioning rod 1, and a plurality of vent holes 2 32 are also provided on the end surface where the connecting section 11 and the positioning section 12 of the positioning rod 1 are connected.

[0019] The present application also discloses a position adjustment method, including the above-mentioned position adjustment tooling, including the following steps: a sleeve step, sleeve the sliding sleeve 2 on the positioning rod 1 with the vent hole 1 31 and the vent hole 2 32, an installation step, install the positioning rod 1 with the vent hole 1 31 and the vent hole 2 32 on the base, and install another positioning rod 1 on the mobile device, an adjustment step, the mobile device adjusts the position of the product, a sliding step, the vent hole 2 32 discharges gas to make the sliding sleeve 2 suspended, and then the vent hole 1 31 discharges gas to correct the position of the sliding sleeve 2, and the sliding sleeve 2 is adjusted. The position of the moving sleeve 2 is collected. If there is any deviation, the sliding sleeve 2 is removed, and the outlet pressure of the vent hole 1 31 and the vent hole 2 32 is adjusted to the maximum outlet pressure for a period of time, and then the sliding sleeve 2 is put on the positioning rod 1 again, and the position is corrected again. If there is still any deviation in the position, the positioning rod 1 is replaced. After the correction is completed (that is, there is no deviation in the position of the sliding sleeve 2), the vent hole 1 31 stops discharging gas, and the outlet pressure of the vent hole 2 32 is periodically adjusted to allow the sliding sleeve 2 to move freely up and down. If it cannot move freely up and down, repeat the adjustment step and this step.

[0020] The implementation principle of this embodiment is: by setting the positioning rod 1 and the sliding sleeve 2, the purpose of higher positioning accuracy can be achieved by moving the position.

[0021] The embodiments of this specific implementation method are all preferred embodiments of the present application, and are not intended to limit the protection scope of the present application. Therefore, all equivalent changes made based on the structure, shape, and principle of the present application should be included in the protection scope of the present application.
