DETAILED DESCRIPTION

[0047] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0048] In the description of the present invention, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "set", "dispose", "connect", and "connect" should be understood in a broad sense, for example, fixed connection, detachable connection, or integral connection; mechanical connection, electrical connection; direct connection, indirect connection through an intermediate medium, or internal communication between two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention should be understood according to specific circumstances.

[0049] like Figure 1-4 As shown, a liftable rotor processing positioning device includes: a base 1, a support frame 2, a bottom plate 3, a lifting mechanism 4, a mounting plate 5, a rotating shaft 6, a turntable 7, a connecting member 8, a sleeve member 9, a clamping member 10, a connecting protrusion 11, and a cylinder 12. Two support frames 2 are provided, and the two support frames 2 are installed above the base 1. The two support frames 2 are arranged opposite to each other and maintain a certain distance, and the reserved distance provides space for other components to be arranged. The base plate 3 is placed on the support frame 2, the lifting mechanism 4 is installed on the base plate 3, the mounting plate 5 is longitudinally installed above the lifting mechanism 4, the rotating shaft 6 is penetrated through the disk surface of the mounting plate 5, the turntable 7 is located in the extension direction of one side of the rotating shaft 6, one end of the connecting member 8 is connected to the turntable 7, and the other end of the connecting member 8 is connected to one side of the rotating shaft 6, one end of the socket 9 is movably connected to the turntable 7, and the other end of the socket 9 is movably connected to one side of the rotating shaft 6, one end of the clamping member 10 is movably installed on the mounting plate 5, and the other end of the clamping member 10 is penetrated through the socket 9, at least three sockets 9 are provided, and the spacing between the three sockets 9 is the same, and the number of clamping members 10 corresponds to the socket 9, so that the more the number of clamping members 10 is, the larger the contact surface with the rotor is.

[0050] Preferably, Figure 4 As shown, the connecting protrusion 11 is arranged on the rotating shaft 6, the cylinder 12 is installed on the mounting plate 5, and the output end of the cylinder 12 is connected to the connecting protrusion 11. Once the cylinder 12 is started, the output end of the cylinder 12 will push the connecting protrusion 11 to rotate, and the connecting protrusion 11 will drive the rotating shaft 6, thereby indirectly driving the rotating disk 7. The movement of the rotating disk 7 and the rotating shaft 6 will cause the sleeve 9 to rotate clockwise, and the rotation of the sleeve 9 will drive the clamping member 10 to shrink and squeeze toward the diameter of the rotating disk 7. Since there are three clamping members 10, the three clamping members 10 can be clamped and fixed by shrinking and squeezing toward the diameter of the rotating disk 7 together.

[0051] In this embodiment, Figure 1-2 As shown, in order to make the height of the utility model freely adjustable and to make it capable of lifting and lowering, a lifting mechanism 4 is designed, including a mounting plate 5 longitudinally mounted on a supporting platform 41, a top of a lifting member 42 fixedly mounted below the supporting platform 41, one end of a screw rod 43 passing through the bottom plate 3, and the other end of the screw rod 43 being sleeved by the bottom of the lifting member 42, a connecting channel being provided at the bottom of the lifting member 42, and an inner diameter of the connecting channel being provided with an internal thread having the same rotation direction as the surface of the screw rod 43, once the screw rod 43 rotates, the lifting member 42 will be driven, and a bearing is provided on the contact surface between the screw rod 43 and the bottom plate 3, which means that the rotation of the screw rod 43 will not drive the bottom plate 3. The main gear 44 is installed at the bottom of the screw rod 43, the power rod 45 is inserted into any one of the support frames 2, the power gear 46 is installed at one end of the power rod 45, and the power gear 46 is meshed with the main gear 44, and the rotating handle 47 is installed at the other end of the power rod 45. When the handle 47 is rotated in any direction, the power gear 46 is driven, and the power gear 46 drives the main gear 44, and finally the main gear 44 drives the screw rod 43, so that power transmission is formed. Two telescopic rods 48 are provided, and the two telescopic rods 48 are located on both sides of the screw rod 43. One end of the telescopic rod 48 is fixedly connected to the bottom of the support platform 41, and the other ends of the two telescopic rods 48 are connected to the bottom plate 3. The setting of the telescopic rod 48 can effectively fix the support platform 41 so that the support platform 41 will not be driven by the rotation of the screw 43. At the same time, since the support platform 41 is connected to the lifting member 42, the lifting member 42 cannot rotate due to the limitation of the support platform 41, and finally the screw 43 rotates the lifting member 42 and moves along the axial direction of the screw 43. The screw 43 is arranged longitudinally, so the axial movement of the lifting member 42 is the up and down movement of the lifting member 42.

[0052] In the above embodiment, the limiting kit 49 is sleeved on the lifting member 42, one end of the support member 410 is connected to the limiting kit 49, and the other end of the support member 410 is fixedly connected to the base plate 3. The setting of the limiting kit 49 can effectively ensure that the lifting member 42 is not prone to shaking during the lifting process, thereby improving the stability of the overall device.

[0053] It should be noted that the utility model is designed to be a kind of lifting rotor processing positioning device. When in use, the rotor is placed in the diameter of the turntable 7, the cylinder 12 is started, and the output end of the cylinder 12 pops out, pushing the connecting protrusion 11 to rotate, and the connecting protrusion 11 will drive the rotating shaft 6 to rotate clockwise. The rotation of the connecting protrusion 11 drives the turntable 7 through the connecting member 8. The movement of the turntable 7 and the rotating shaft 6 will cause the sleeve 9 to rotate clockwise, and the rotation of the sleeve 9 will drive the clamping member 10 to shrink and squeeze toward the diameter of the turntable 7. Since there are three clamping members 10, the three clamping members 10 can be squeezed toward the diameter of the turntable 7 together to fix the rotor. When the height needs to be adjusted during processing, the handle 47 is manually rotated, and the rotation of the handle drives the power gear 46, which drives the main gear 44 meshing therewith, and the main gear 44 drives the screw 43, which drives the lifting member 42. The lifting member 42 changes from rotation to up and down displacement due to the indirect restriction of the telescopic rod 48, and the up and down displacement of the lifting member 42 drives the support platform 41 and the clamping and fixing components above it. At this point, the height adjustment process ends.

[0054] Although the embodiments of the present invention have been shown and described, it will be apparent to those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
