Description

Technical Field

[0001] This utility model relates to the field of rotor hub technology, specifically to a tooling structure for drilling and reaming pin holes. Background Technology

[0002] The rotor hub is one of the core components of a motor or starter rotor, typically forming a complete rotor structure together with rotor blades, rotor shaft, and other parts. In hub motor technology, the design of the rotor hub directly affects the motor's performance.

[0003] Existing equipment requires positioning the rotor hub before processing to prevent it from shifting during processing. If the rotor hub is not firmly positioned during processing, it is prone to rotational misalignment, which affects the normal processing of the rotor hub. Utility Model Content

[0004] The purpose of this utility model is to provide a tooling structure for drilling and reaming pin holes to solve the problems mentioned in the background art.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0006] A tooling structure for drilling and reaming pin holes includes a tooling base plate, a rotor hub body is disposed above the tooling base plate, and a support component, a clamping component and a centering component are disposed at the upper end of the tooling base plate.

[0007] The clamping component includes lever cylinders fixedly connected to the four corners of the upper end of the tooling base plate. A cylinder lever seat is fixedly connected to the inner side of the upper end of the lever cylinder. Lever cylinder support blocks are movably connected to both sides of the upper end of the cylinder lever seat. A lever cylinder pressure plate is provided on the inner side of the upper end of the lever cylinder support block. A cylinder piston rod is provided at the center of the upper end of the lever cylinder.

[0008] A further improvement of this utility model is that: the output end of the lever cylinder pressure plate faces the center of the tooling base plate; the cylinder lever seat and the lever cylinder are connected by a screw; and the upper end of the cylinder piston rod is movably connected to the outer end of the lever cylinder pressure plate.

[0009] Using the above technical solution, the inner end of the lever cylinder pressure plate is supported by the lever cylinder support block, and the upper end of the rotor hub body is pressed down and fixed by the downward movement of the inner end of the lever cylinder pressure plate. By fixing the cylinder piston rod to the upper end of the lever cylinder, the position of the inner end of the lever cylinder pressure plate can be changed by raising and lowering the cylinder piston rod.

[0010] A further improvement of the present invention is that the supporting component includes a workpiece buffer cylindrical seat, a workpiece cylindrical pad, and an directional cylindrical seat, all uniformly fixed to the upper end of the tooling base plate, and a workpiece buffer cylindrical top rod is snapped into the upper end of the workpiece buffer cylindrical seat.

[0011] A further improvement of this utility model is that: four sets of workpiece buffer cylindrical seats are provided, two sets of workpiece cylindrical pads are provided, and two sets of directional cylindrical seats are provided. The workpiece buffer cylindrical seats and workpiece cylindrical pads are staggered, and the directional cylindrical seats are located on the inner side between the workpiece buffer cylindrical seats and workpiece cylindrical pads.

[0012] The above technical solution uses a workpiece cylindrical pad to support the lower end of the rotor hub body, and a workpiece buffer cylindrical top rod to reduce the downward impact force on the workpiece cylindrical pad, thereby increasing the service life of the workpiece cylindrical pad. The rotor hub body is oriented by passing through the notch of the rotor hub body through the directional cylindrical seat, so as to prevent the rotor hub body from rotating accidentally.

[0013] A further improvement of this utility model is that: the centering component includes a center guide sleeve fixedly connected to the upper center position of the tooling base plate; spring cover plates are fixedly connected to both sides of the center guide sleeve; a V-shaped positioning movable block seat is provided on the outer side of the spring cover plate; a V-shaped positioning movable block body is slidably engaged inside the outer side of the V-shaped positioning movable block seat; an anti-misalignment cylindrical rod is fixedly connected to the outer side of the V-shaped positioning movable block seat; a center guide sleeve body and a movable center washer are engaged inside the center guide sleeve seat; and a movable center body is provided inside the center guide sleeve seat.

[0014] A further improvement of this utility model is that: the spring cover plate is connected to the V-shaped positioning movable block seat through the lower spring hole, the output end of the V-shaped positioning movable block body faces the outside of the top guide sleeve seat, the anti-misalignment cylindrical rod is located on both sides of the V-shaped positioning movable block body, and the lower end of the anti-misalignment cylindrical rod is fixedly connected to the upper end of the tooling base plate.

[0015] Using the above technical solution, the V-shaped positioning movable block body is limited by the anti-misalignment cylindrical rod, and the position of the V-shaped positioning movable block seat is determined.

[0016] A further improvement of this utility model is that: the upper end of the movable tip body is positioned above the tip guide sleeve body, and the lower end of the movable tip body passes through the interior of the tip guide sleeve body and is connected to the upper end of the movable tip washer.

[0017] By adopting the above technical solution, the movable center body is limited and supported by the center guide sleeve body and the movable center washer. By extending and retracting the movable center body, the position of the exposed end of the movable center body is changed, so that the exposed end of the movable center body can enter the center position of the rotor hub body, thereby centering the rotor hub body.

[0018] Due to the adoption of the above technical solution, the technological progress achieved by this utility model compared to the prior art is as follows:

[0019] 1. This utility model provides a tooling structure for drilling and reaming pin holes. It adopts the cooperation of a clamping component, a lever cylinder, a cylinder lever seat, a lever cylinder support block, a lever cylinder pressure plate, and a cylinder piston rod. By raising and lowering the cylinder piston rod, the position of the inner end of the lever cylinder pressure plate is changed. By moving the inner end of the lever cylinder pressure plate downward, the upper end of the rotor hub body is pressed down and tightened. Thus, under the mutual cooperation of the workpiece cylindrical pad and the lever cylinder pressure plate, the rotor hub body is limited and fixed.

[0020] 2. This utility model provides a tooling structure for drilling and reaming pin holes. It adopts the cooperation of a support component, a workpiece buffer cylindrical seat, a workpiece buffer cylindrical top rod, a workpiece cylindrical pad, and a directional cylindrical seat. The workpiece cylindrical pad provides support force to the rotor hub body to prevent the rotor hub body from collapsing. The workpiece buffer cylindrical top rod buffers the heavy pressure on the workpiece cylindrical pad to enhance the service life of the workpiece cylindrical pad. The directional cylindrical seat directionally limits the rotor hub body to prevent the rotor hub body from rotating and shifting during processing.

[0021] 3. This utility model provides a drilling and reaming pin hole tooling structure, which adopts the cooperation of a centering component, a center guide sleeve seat, a V-shaped positioning movable block seat, a spring cover plate, a V-shaped positioning movable block, a center guide sleeve, a movable center washer, a movable center body, and an anti-misalignment cylindrical rod. By raising and lowering the movable center body, the exposed end of the movable center body can enter the center hole of the rotor hub body, thereby centering the rotor hub body under the interaction of the center hole and the movable center body. Since its movable center body is telescopic, the rotor hub body can be repeatedly clamped and processed. Attached Figure Description

[0035] like Figure 1-5As shown, based on Embodiment 1, this utility model provides a technical solution: preferably, the support component 4 includes a workpiece buffer cylindrical seat 41, a workpiece cylindrical pad 43 and an directional cylindrical seat 44 uniformly fixed on the upper end of the tooling base plate 1, and a workpiece buffer cylindrical top rod 42 is snapped into the upper end of the workpiece buffer cylindrical seat 41.

[0036] The workpiece buffer cylindrical seat 41 is provided in four sets, the workpiece cylindrical pad 43 is provided in two sets, and the directional cylindrical seat 44 is provided in two sets. The workpiece buffer cylindrical seat 41 and the workpiece cylindrical pad 43 are staggered and distributed.

The rotor hub body 2 is oriented by the directional cylindrical seat 44 passing through the notch of the rotor hub body 2 to prevent the rotor hub body 2 from rotating accidentally.

[0038] Example 3

[0039] like Figure 1-5 As shown, based on Embodiment 1, this utility model provides a technical solution: Preferably, the centering component 5 includes a top guide sleeve seat 51 fixedly connected to the center position of the upper end of the tooling base plate 1. Spring cover plates 53 are fixedly connected to both sides of the top guide sleeve seat 51. A V-shaped positioning movable block seat 52 is provided on the outer side of the spring cover plate 53. A V-shaped positioning movable block body 54 is slidably engaged inside the outer side of the V-shaped positioning movable block seat 52. An anti-misalignment cylindrical rod 58 is fixedly connected to the outer side of the V-shaped positioning movable block seat 52. A top guide sleeve body 55 and a movable top washer 56 are engaged inside the top guide sleeve seat 51. A movable top body 57 is provided inside the top guide sleeve seat 51.

[0040] The spring cover plate 53 is connected to the V-shaped positioning movable block seat 52 through the spring hole on the lower side. The output end of the V-shaped positioning movable block body 54 faces the outside of the center guide sleeve seat 51. The anti-mistake cylindrical rod 58 is located on both sides of the V-shaped positioning movable block body 54. The lower end of the anti-mistake cylindrical rod 58 is fixedly connected to the upper end of the tooling base plate 1. The upper end of the movable center body 57 is placed above the center guide sleeve body 55. The lower end of the movable center body 57 passes through the interior of the center guide sleeve body 55 and is connected to the upper end of the movable center washer 56.

[0041] In this embodiment, the V-shaped positioning movable block body 54 is limited by the anti-misalignment cylindrical rod 58, and the position of the V-shaped positioning movable block seat 52 is determined. The movable top body 57 is limited and supported by the top guide sleeve body 55 and the movable top washer 56.

[0042] The working principle of this drilling and reaming pin hole tooling structure will be explained in detail below.

[0043] like Figure 1-5 As shown, when it is necessary to position the rotor hub body 2, first align the center hole of the rotor hub body 2 with the upper end of the movable tip body 57, and push the rotor hub body 2 down so that its center hole passes through the exposed end of the movable tip body 57. At this time, the rotor hub body 2 can be centered under the mutual cooperation of the center hole and the movable tip body 57. Thus, the rotor hub body 2 is placed on the upper end of the workpiece buffer cylindrical top rod 42 and the workpiece cylindrical pad 43, and the directional cylindrical seat 44 passes through the notch of the rotor hub body 2. At this time, the rotor hub body 2 is supported under the mutual cooperation of the workpiece buffer cylindrical top rod 42 and the workpiece cylindrical pad 43, and the rotor hub body 2 is oriented under the action of the directional cylindrical seat 44.

[0044] Then the cylinder piston rod 35 can be extended to push the outer end of the lever cylinder pressure plate 34 upward. Under the limiting action of the lever cylinder support block 33, the outer end of the lever cylinder pressure plate 34 is driven to move downward until the outer end of the lever cylinder pressure plate 34 touches the upper end of the rotor hub body 2, so as to press down and fasten the rotor hub body 2.

[0045] Furthermore, the exposed end of the movable tip body 57 can be disengaged from the center hole of the rotor hub body 2 by extending and retracting the movable tip body 57, so as to facilitate repeated clamping and processing of the rotor hub body 2.

[0046] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
