DETAILED DESCRIPTION

[0021] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Generally, the components of the embodiments of the present invention described and shown in the drawings herein can be arranged and designed in various different configurations.

[0022] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but rather merely represents selected embodiments of the present invention. All other embodiments derived by persons of ordinary skill in the art based on the embodiments of the present invention without creative effort are also within the scope of protection of the present invention.

[0023] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, it does not need to be further defined or explained in subsequent drawings.

[0024] The following is further described in conjunction with specific embodiments. Figure 1-Figure 3 As shown, this embodiment is a tool for improving the efficiency and accuracy of rotor processing, including a hydraulic inner support clamp 1, the hydraulic inner support clamp 1 is covered with a tightening sleeve 2 on the outside, and the tightening sleeve 2 is used to clamp into the inner hole of the rotor; an oil injection chamber 121 is provided in the hydraulic inner support clamp 1, and the rotor is clamped by inputting hydraulic oil into the oil injection chamber 121 to squeeze and expand the tightening sleeve 2; specifically, the rotor body 3 to be processed is sleeved on the tightening sleeve 2, and the hydraulic oil in the oil injection chamber 121 is adjusted to increase the pressure so that the hydraulic inner support clamp 1 is slightly deformed, and the diameter of the tightening sleeve 2 is enlarged to tighten the inner hole of the rotor body 3 to complete the clamping. The operation is simple and convenient, and the processing efficiency is effectively improved.

[0025] like Figure 2 As shown, the specially designed front and back integrated tools process the two end faces of the rotor, and the processing of the two end faces is completed in one clamping, and the parallelism and flatness are better controlled.

[0026] like Figure 2 As shown, the hydraulic internal support clamp 1 in this embodiment includes a main body 11 and a clamping part 12, an oil filling chamber 121 is provided in the clamping part 12, the main body 11 is provided with an oil storage chamber 111 communicated with the oil filling chamber 121, and the main body 11 is provided with a blocking screw 13 that is stuck in the oil storage chamber 111; specifically, hydraulic oil can be injected into the blocking screw 13 by opening it.

[0027] In this embodiment, a pressure-adjusting screw 14 is provided at the front end of the clamping portion 12, and one end of the pressure-adjusting screw 14 is communicated with the oil filling chamber 121. Specifically, by loosening the pressure-adjusting screw 14 with a tool, the pressure in the oil filling chamber 121 is reduced, causing the tightening sleeve 2 to expand and contract, thereby allowing the rotor body 3 to be separated from the tightening sleeve 2. The clamping can achieve the expansion and release of the rotor body 3 only by the pressure-adjusting screw 14.

[0028] More preferably, in some embodiments, the size of the clamping portion 12 is smaller than the main body 11, and the main body 11 is provided with a positioning protrusion 112 on the side facing the clamping portion 12; specifically, while the tightening sleeve 2 expands the inner hole of the rotor body 3, the end face of one side of the rotor body 3 is pressed against the positioning protrusion 112 during processing.

[0029] like Figure 3As shown, the variable sleeve 2 is provided with at least two deformation seams 22 arranged along the axial direction. Through the circumferential tensioning of the hydraulic expansion clamp, the tensioning force of the clamp is more uniform, and the axial force is also prevented, so as to prevent the plane distortion of the flange surface caused by the uneven force when the rotor passes through the three-claw inner jump or the outer circle clamp.

[0030] Several tightening racks 21 are evenly spaced on the outer circle of the tightening sleeve 2; the tightening racks 21 are set along the axis of the tightening sleeve 2, and the tightening racks 21 are conical structures; specifically, there are four external teeth on the tightening sleeve 2 that match the middle diameter of the spline internal teeth of the rotor body 3, and its positioning accuracy is higher, avoiding circumferential rotation during the processing.

[0031] Furthermore, the variable sleeve 2 is a cylindrical structure, and two deformation joints 22 are symmetrically distributed.

[0032] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Those skilled in the art will readily appreciate that the present invention is susceptible to various modifications and variations. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
