[0032] The positioning block 1 is fixedly mounted on an external component that needs to be positioned, and the bottom plate 7 is fixedly mounted on another component that needs to be positioned; the positioning of the two components is achieved by inserting the positioning column 3 into the positioning block 1;

[0033] Two second mounting plates 6 are fixedly mounted on the bottom plate 7;

[0034] The two first mounting plates 4 are respectively fixedly mounted on the bottom plate 7, and the two first mounting plates 4 are respectively located on the outer sides of the two second mounting plates 6;

[0035] Each first mounting plate 4 has a set of transmission components installed inside, and the motor 2 drives any one of the two sets of transmission components to move as the active end;

[0036] The transmission assembly is connected to the second mounting plate 6 via a sliding assembly; the positioning column 3 is fixedly mounted on the transmission assembly, and the sliding assembly drives the transmission assembly and the positioning column 3 to perform telescopic movement;

[0037] The sliding assembly includes: a slider 12, a guide rail 13 and a positioning column bottom plate 8. The guide rail 13 is fixedly mounted on the second mounting plate 6, and the slider 12 is fixedly mounted on the positioning column bottom plate 8. The slider 12 can slide relative to the guide rail 13; the slider 12 is fixedly connected to the transmission assembly;

[0038] The positioning column 3 is installed on the positioning column base plate 8 and moves along with the positioning column base plate 8 .

[0039] The transmission assembly includes: a rack 9, a large gear 10 and a small gear 11. The rack 9 is mounted on the positioning column base plate 8 and meshes with the large gear 10;

[0040] The large gear 10 and the small gear 11 are respectively mounted on the first mounting plate 4, and the large gear 10 and the small gear 11 are meshed with each other. The motor 2 drives the small gear 11 to rotate.

[0041] The positioning column 3 is any one of a truncated cone, a stepped cone, a cylindrical cone or a rectangular cone. The inner hole shape of the positioning block 1 cooperates with the structure of the positioning column 3 to achieve plug-in positioning.

[0042] The tops of the two second mounting plates 6 are fixedly connected by a connecting beam 14; the position of the connecting beam 14 avoids the movement space of the positioning column 3. The connecting beam 14 connects the two mounting plates to strengthen the strength between the mounting plates. The positioning column 3 extends out of the plane where the connecting beam 14 is located and is inserted into the positioning block 1.

[0043] The manual column 5 is installed on the shaft of the pinion 11 , and the manual column 5 is manually rotated using a wrench to drive the pinion 11 to move to lift and lower the positioning column 3 .

[0044] The manual column 5 is in the shape of a quadrilateral or a hexagon, and its size is not limited. The manual column 5 is installed on the pinion 11 to reduce the required torque of the lifting positioning process.

[0045] like Figure 1 As shown, the utility model is a nozzle positioning device, the active mounting plate is mounted on the bottom plate 7, the large gear 10 is meshed with the small gear 11 and mounted on the first mounting plate 4, and the motor 2 and the hexagonal column are respectively mounted at both ends of the small gear 11. The passive mounting plate is symmetrically mounted on the bottom plate 7 with respect to the positioning column 3. Except that the motor 2 is not mounted, the rest of the parts are the same as the active mounting plate, and will not be described again.

[0046] The second mounting plate includes: a left second mounting plate and a right second mounting plate. The left second mounting plate 6-1 is mounted on the bottom plate 7, the guide rail 13 is mounted on the left second mounting plate 6-1, the slider 12 is used in conjunction with the guide rail 13, the positioning column bottom plate 8 is connected to the slider 12, and can drive the positioning column bottom plate 8 to move up and down.

[0047] The first mounting plate 4 and the second mounting plate 6 have a bearing function for components such as gears, and their shapes and thicknesses are not limited.

[0048] The large gear 10 meshes with the small gear 11 and rotates, thereby driving the rack 9 to move up and down, so that the rotation of the small gear 11 itself is converted into an up and down linear motion.

[0049] The slider 12 is installed on the positioning base plate 7, and the guide rail 13 is installed on the second mounting plate 6. The slider 12 and the guide rail 13 are used together to provide guidance for the positioning column base plate 8 to move up and down, and there is no limitation on the specific model and size.

[0050] The rack 9 is mounted on the positioning column bottom plate 8 , and the positioning column 3 is also mounted on the positioning bottom plate 7 . The positioning column 3 and the positioning bottom plate 7 are driven by the rack 9 to move up and down.

[0051] The module and the number of teeth of the large and small gears 11 and the rack 9 can be flexibly selected according to requirements without restriction.

[0052] The entire device is driven by a motor 2. The rotation of the motor 2 drives the gear to rotate, and the gear drives the rack 9 to move up and down, thereby driving the positioning column 3 to insert into the positioning block 1 to achieve the positioning requirements.

[0053] The large and small gears 11 and the first mounting plate 4 have two sets in total and are arranged symmetrically, thereby improving the versatility of the positioning device.

[0054] The positioning block 1 is installed on a component that needs to be positioned, and the rest is installed on another component that needs to be positioned. Positioning is achieved by inserting the positioning column 3 into the positioning block 1. The positioning column 3 is installed on the positioning column base plate 8 and is driven by the slider 12 to move on the guide rail 13. A rack 9 is installed at the other end of the positioning column base plate 8, which cooperates with the gear, and the gear is driven by the motor 2.

[0055] When the parts move into place, the motor 2 rotates, driving the pinion 11 to rotate, and the pinion 11 meshes and rotates with the large gear 10, driving the rack 9 to move upward. The rack 9 drives the positioning column base plate 8 to move upward, so that the positioning column 3 is inserted into the positioning block 1, and the positioning is completed by the cooperation between the positioning block 1 and the positioning column 3.

[0056] When the component does not need to be positioned, the motor 2 is reversed to drive the gear rack 9 to rotate, so that the positioning column 3 moves downward and the positioning column 3 is separated from the positioning block 1.

[0057] If the motor 2 cannot be used, use an inner hexagonal wrench to rotate the outer hexagonal column at the other end of the pinion 11, and manually rotate the pinion 11 to drive the positioning column 3 to move up and down.

[0058] The large gear 10, the small gear 11 and the rack 9 are symmetrically arranged on the bottom plate 7 to increase the versatility of the mechanism.

[0059] There are two sets of large and small gears 11 and the first mounting plate 4 and they are arranged symmetrically, which improves the versatility of the entire device.

[0060] The utility model has a small mechanism and can realize positioning with a large driving force in a small size. The utility model can be arranged in multiple units and used as a set at the position where positioning is required. The utility model adopts the motor 2 as a drive, can automate the positioning process and has a simple control method, which is conducive to realizing the automation of wind tunnel equipment.
