Description

Technical Field

[0001] The utility model belongs to the technical field of stator dove tail reinforcement welding, in particular to a convenient stator dove tail reinforcement elastic element adjustment device. Background Art

[0002] During motor manufacturing, welding the stator dovetail ribs is a critical step. To ensure the strength and precision of the connection between the stator dovetail ribs and the stator core, the elastic element block must be precisely adjusted and fixed. However, existing stator dovetail rib elastic element adjustment devices have the following problems and shortcomings:

[0003] Existing devices typically use single- or multi-point clamping, but achieving uniform clamping force distribution is often difficult. Excessive clamping force or uneven clamping designs often lead to permanent deformation of the elastic element during adjustment. This deformation not only affects the performance of the elastic element but can also reduce the overall quality and service life of the product. Utility Model Content

[0004] The purpose of the utility model is to provide a convenient stator dovetail rib elastic element adjustment device to solve the problems raised in the background technology.

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solution: a convenient stator dovetail rib elastic element adjustment device, comprising:

[0006] The dovetail rib elastic member adjustment assembly comprises a mounting base mounted on the stator dovetail rib welding machine and a convex adjustment tooling arranged on the top surface of the mounting base;

[0007] The elastic element block is arranged directly below the convex adjustment fixture and above the mounting base plate;

[0008] The adjusting bolts are symmetrically and centripetally passed through the convex adjusting fixture, and the screw ends of the two adjusting bolts at opposite ends are rotatably connected to the stable clamping members, and the two stable clamping members are clamped and matched on the outer wall of the elastic element block;

[0009] The upper and lower extended abutment members are respectively symmetrically fixed to the upper and lower outer walls of the stable clamping member and the friction abutment plate is integrally connected to the free end of the elastic inclined top plate. When the stable clamping member clamps the elastic element block, the two adjacent stable clamping members are elastically abutted and expanded, so that the friction abutment plate frictionally abuts against the outer wall of the elastic element block.

[0010] Preferably, a fixing collar is fixedly mounted on the middle position of the back side of each of the stabilizing clamping members, and a sealed bearing is interference-fitted in the fixing collar.

[0011] Preferably, the screw rod end of the adjusting bolt is interference fit with the inner ring of the sealed bearing. When the adjusting bolt is screwed into the convex adjustment fixture, the adjusting bolt pushes the stabilizing clamping part to move toward the elastic element block, and the two stabilizing clamping parts are centripetally clamped on the elastic element block.

[0012] In this solution, the stable clamping member is a horizontal U-shaped structure, and the stable clamping member is clamped and connected to the outside of the elastic element block.

[0013] Preferably, in this solution, a section of the inner wall between the elastic inclined top plate and the friction abutment plate is provided with a chamfered top connection portion, and the chamfered top connection portion abuts against the outer wall of the elastic element block.

[0014] Preferably, the rounded top connection portion and the inner wall of the friction abutment plate are both provided with anti-slip convex points, and the anti-slip convex points are in frictional contact with the outer wall of the elastic element block.

[0015] Preferably, a positioning rib support block is provided on the top surface of the installation base plate and directly below the convex adjustment fixture, and the elastic element block is embedded in the positioning rib support block.

[0016] Preferably, an internal thread column is fixed to the top surface of the convex adjustment fixture, an adjusting top screw is threadedly connected to the internal thread column, a connecting column is welded to the top end of the adjusting top screw, and a ring plate is connected to the circumference of the connecting column.

[0017] Preferably, the bottom surface of the convex adjustment fixture is provided with four mounting recessed holes in a rectangular shape, and a compression spring is provided in each of the mounting recessed holes.

[0018] Preferably, the upper and lower ends of the extrusion spring are fixedly connected to rubber pads, and the surfaces of the two rubber pads have anti-slip pads. When the mounting base is installed on the dovetail rib welding machine, the extrusion spring and the two rubber pads can provide buffering and shock absorption for the mounting base in the mounting recessed hole, and the anti-slip pads can prevent slipping.

[0019] Compared with the prior art, the technical effects and advantages of this utility model are:

[0020] This convenient stator dovetail rib elastic element adjustment device utilizes symmetrically arranged adjustment bolts and a secure clamping element to achieve uniform and precise clamping of the elastic element block. This design reduces the risk of deformation caused by uneven clamping force, thereby improving overall adjustment accuracy. The adjustable jackscrew and connecting column design allow for fine-tuning of the height of the convex adjustment fixture, ensuring that the elastic element block is accurately positioned in the desired location.

[0021] The elastically inclined top plate and friction plate in the lower extension abutment expand outward during clamping, increasing the contact area with the outer wall of the elastic element block. This multi-point contact design not only improves clamping stability but also disperses the clamping force, reducing localized stress concentration. The rounded top contact and anti-slip bumps increase friction, further strengthening the clamping force and preventing the elastic element block from slipping during operation.

[0022] Adjusting the bolts to drive the clamping force of the stabilizer is less than the elastic capacity of the elastic element, thus preventing permanent deformation caused by over-clamping. The symmetrical design of the stabilizer ensures that the clamping force is evenly distributed across the elastic element, reducing local stress concentration and the risk of deformation.

[0031] In the following description, numerous specific details are provided to provide a more thorough understanding of the present invention. However, it will be apparent to those skilled in the art that the present invention can be practiced without one or more of these details. In other instances, certain technical features known in the art are not described to avoid confusion with the present invention.

[0032] Unless otherwise defined, the directions of up, down, left, right, front, back, inside and outside involved in this document are based on the directions of up, down, left, right, front, back, inside and outside shown in the figures of the present invention, and are explained here together.

[0033] This embodiment provides Figures 1 to 5 A convenient stator dovetail rib elastic element adjustment device shown includes: a dovetail rib elastic element adjustment assembly 1, an elastic element block 5, an adjustment bolt 6, and upper and lower extension abutment members 15.

[0034] In this embodiment, the dovetail rib elastic member adjustment assembly 1 comprises a mounting base 3, mounted on a stator dovetail rib welding machine, and a convex adjustment fixture 2, mounted on the top surface of the mounting base 3. The convex adjustment fixture 2 provides a fixed frame for supporting other components and, through mechanisms such as internally threaded posts, allows for fine-tuning of the position of the stabilizing clamp 11. Its bottom surface features a mounting recess 19, which, in conjunction with a compression spring 21 and a rubber pad 20, absorbs vibration and prevents slippage.

[0035] In this embodiment, the elastic element block 5 is disposed directly below the convex adjustment fixture 2 and above the mounting base plate 3 .

[0036] In this embodiment, the adjustment bolt members 6 are symmetrically and centripetally penetrated into the convex adjustment fixture 2 , and the screw ends of the two adjustment bolt members 6 at opposite ends are rotatably connected to the stable clamping members 11 , and the two stable clamping members 11 are clamped and fit on the outer wall of the elastic element block 5 .

[0037] In this embodiment, the upper and lower extended abutment members 15 are symmetrically fixed to the upper and lower outer walls of the stable clamping member 11, respectively, and the friction abutment plates 16 are integrally connected to the free ends of the elastic inclined top plates 14. When the stable clamping member 11 clamps the elastic element block 5, the two adjacent stable clamping members 11 are elastically abutted and expanded, causing the friction abutment plates 16 to frictionally abut against the outer walls of the elastic element block 5. When the upper and lower elastic inclined top plates 14 on the same side clamp the elastic element block 5, they are in an expanded state and can abut the elastic element block 5 toward the upper and lower sides through the friction abutment plates 16, thereby increasing the stability of the elastic element block 5 and reducing the displacement and deformation of the elastic element block 5. At the same time, the clamping force of the stable clamping member 11 driven by the adjustment bolt member 6 is less than the elastic bearing capacity of the elastic element block 5, so that the elastic element block 5 will not be deformed by the clamping force. When the secure clamp 11 is tightened, the upper and lower extension abutment members 15 and their component parts, the elastically inclined top plate 14 and friction abutment plate 16, expand outward, increasing the contact area with the surface of the elastic element block 5, improving stability while reducing any potential displacement or deformation. The rounded top contact portion 17 and anti-slip bumps 18 help better conform to the shape of the elastic element block 5, increasing friction and preventing slippage.

[0038] In this embodiment, a fixing collar 12 is fixedly mounted at the middle position of the back side of each stabilizing clamping member 11 , and a sealing bearing 13 is interference-fitted in the fixing collar 12 .

[0039] In this embodiment, the smooth rod end of the screw of the adjusting bolt component 6 is interference fit with the inner ring of the sealing bearing 13. When the adjusting bolt component 6 is screwed into the convex adjustment tooling 2, the adjusting bolt component 6 pushes the stabilizing clamping component 11 to move toward the elastic element block 5, and the two stabilizing clamping components 11 are centripetally clamped on the elastic element block 5.

[0040] In this embodiment, the stabilizing clamping member 11 is a horizontal U-shaped structure that clamps and engages the exterior of the elastic element block 5. The stabilizing clamping member 11 is symmetrically positioned on either side of the elastic element block 5 and can be moved centripetally by adjusting the bolt member 6 to tightly and evenly clamp the elastic element block 5. This symmetrical design ensures even distribution of clamping force and prevents tilting or displacement of the elastic element block 5.

[0041] In this embodiment, a section of the inner wall between the elastic inclined top plate 14 and the friction contact plate 16 is provided with a rounded top connecting portion 17 , and the rounded top connecting portion 17 contacts the outer wall of the elastic element block 5 .

[0042] In this embodiment, the inner walls of the rounded top connection portion 17 and the friction abutment plate 16 are both provided with anti-slip bumps 18, which are in frictional contact with the outer wall of the elastic element block 5. The rounded top connection portion 17 and the anti-slip bumps 18 increase the friction between the friction abutment plate 16 and the elastic element block 5, further ensuring the secure clamping.

[0043] In this embodiment, a positioning rib support block 4 is provided on the top surface of the mounting base plate 3 and directly below the convex adjustment fixture 2, and the elastic element block 5 is embedded in the positioning rib support block 4. The positioning rib support block 4 provides a stable placement position for the elastic element block 5, ensuring that it will not be displaced or tilted unnecessarily when being adjusted. The elastic element block 5 is the target object that needs to be adjusted, and this device can apply an appropriate clamping force to it without causing deformation, thereby ensuring that its performance is not affected. The positioning rib support block 4 provides a stable placement position for the elastic element block 5, and it is embedded in the mounting base plate 3, so that the elastic element block 5 is already in a fixed position before being clamped, reducing uncertainty in the adjustment process.

[0044] In this embodiment, an internally threaded post 7 is fixed to the top surface of the convex adjustment fixture 2. An adjustment screw 9 is threadedly connected to the internally threaded post 7. A connecting post 10 is welded to the top of the adjustment screw 9. A ring plate 8 is attached to the circumference of the connecting post 10. Stabilizing clamps 11 directly contact and clamp the elastic element block 5 to maintain its correct position. The back of each stabilizing clamp 11 is equipped with a fixing collar 12 and a sealed bearing 13 to ensure smooth movement and eliminate the risk of leakage.

[0045] In this embodiment, the bottom surface of the convex adjustment fixture 2 is provided with four mounting recesses 19 distributed in a rectangular shape, and a compression spring 21 is provided in each mounting recess 19 .

[0046] In this embodiment, the upper and lower ends of the extrusion spring 21 are fixedly connected to rubber pads 20, and the surfaces of the two rubber pads 20 are provided with anti-slip pads 22. When the mounting base 3 is installed on the dovetail rib welding machine, the extrusion spring 21 and the two rubber pads 20 can provide cushioning and shock absorption for the mounting base 3 in the mounting recess 19, while the anti-slip pads 22 can also prevent slipping. The mounting recess 19, the rubber pads 20, and the extrusion spring 21 act together on the bottom of the convex adjustment fixture 2, providing a shock-absorbing mechanism that helps reduce the impact of external vibrations on the adjustment process and also enhances the safety of the entire device. The anti-slip pads 22 further enhance this buffering effect and prevent the equipment from accidentally moving during operation. The anti-slip pads 22 on the rubber pads 20 enhance the friction between the rubber pads 20 and the work surface, preventing the entire device from sliding unnecessarily during operation.

[0047] Working principle:

[0048] This convenient stator dovetail rib elastic element adjustment device first secures the entire device to the stator dovetail rib welding machine via the mounting base 3 to ensure stability. The elastic element block 5 to be adjusted is then placed on the positioning rib support block 4 to ensure it is correctly positioned. If necessary, the height of the convex adjustment fixture 2 can be fine-tuned by adjusting the jackscrew 9 and connecting column 10 to maintain an appropriate distance from the elastic element block 5.

[0049] Rotate the adjustment bolt 6 to move the stabilizing clamp 11 centripetally and gradually approach the elastic element block 5. Since the smooth rod end of the screw of the adjustment bolt 6 is interference fit with the inner ring of the sealed bearing 13, the stabilizing clamp 11 will move smoothly toward the elastic element block 5 when rotating. Continue to rotate the adjustment bolt 6 until the two stabilizing clamps 11 clamp the elastic element block 5 evenly and symmetrically. During this process, pay attention to controlling the clamping force to ensure that it does not exceed the elastic bearing capacity of the elastic element block 5 to prevent deformation. As the stabilizing clamp 11 is clamped, the elastic inclined top plate 14 and the friction abutment plate 16 in the upper and lower extended abutments 15 will expand outward, increasing the contact area with the outer wall of the elastic element block 5. The rounded top connection 17 and the anti-slip bumps 18 further increase the friction, increase stability, and reduce local stress concentration.

[0050] If further adjustment of the height or position of the elastic element block 5 is required, fine-tuning can be performed by adjusting the top screw 9. Rotating the top screw 9 changes the distance between the convex adjustment fixture 2 and the mounting base 3, thereby achieving fine height adjustment. Throughout the adjustment process, the operator should constantly check the position and condition of the elastic element block 5 to ensure that it meets the expected requirements. Any deviation should be corrected promptly.

[0051] The four mounting recesses 19 on the bottom of the convex adjustment fixture 2 house compression springs 21 and rubber pads 20. These components absorb vibration and shock during operation, reducing the impact of external factors on adjustment accuracy. The non-slip pads 22 on the rubber pads 20 provide additional friction, preventing vibration-induced displacement during adjustment.

[0052] After completing all necessary adjustments, check again whether the elastic element block 5 is firmly and accurately located in the desired position. After confirmation, the next step can be carried out, such as welding or other processing.

Moreover, the terms "include", "comprise" or any other variations thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device that includes a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.
