Description

Technical Field

[0001] This utility model relates to the field of edge and corner grinding technology, and in particular to an edge and corner grinding device for locomotive parts. Background Technology

[0002] The locomotive parts edge grinding equipment is a specially designed and manufactured mechanical device used to grind the edges and corners of various locomotive parts. This equipment aims to solve problems such as burrs, flash, dimensional deviations, and substandard surface roughness that exist at the edges and corners during the production or maintenance of locomotive parts.

[0003] Currently, handheld grinders are commonly used for grinding the edges and corners of locomotive parts. They require no complicated installation or debugging process; simply connect a power source or install a battery, and they are ready to use. New employees can quickly learn to operate them after simple training, reducing training costs and lowering the operational threshold. They can be quickly deployed in routine locomotive maintenance and repair scenarios.

[0004] While handheld grinders offer high flexibility, the angles of parts during grinding rely entirely on manual adjustment by the operator, lacking automatic adjustment capabilities. For complex-shaped locomotive parts requiring grinding from multiple angles, operators must constantly adjust the grinding angle and position based on experience and feel, resulting in low efficiency, difficulty in guaranteeing grinding accuracy, and significant differences in grinding effects between different operators. Therefore, this paper proposes a locomotive parts edge grinding device to address these issues. Utility Model Content

Detailed Implementation

[0034] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0035] Reference Figure 1 and Figure 2 An embodiment of this utility model provides: a grinding device for the edges and corners of locomotive parts, including a base plate 1 and a grinding disc 4. A rotating housing 9 is fixedly connected to the side of the base plate 1. A rotating assembly is provided inside the rotating housing 9. A connecting block 2 8 is fixedly connected to the side of the rotating housing 9. A spacing adjustment assembly is provided inside the connecting block 2 8. Two connecting blocks 1 5 are slidably connected to the outside of the connecting block 2 8. A clamping assembly is provided inside the two connecting blocks 1 5. An angle adjustment assembly is provided inside the two connecting blocks 1 5. A connecting plate 2 is fixedly connected to the outside of the base plate 1. A grinding assembly is provided on the side of the connecting plate 2.

[0036] The angle adjustment assembly includes two limiting circular plates 17, which are rotatably connected to the inner sides of two connecting blocks 5. A bracket plate 6 is fixedly connected to the outer side of one of the connecting blocks 5, and a drive motor 18 is fixedly connected to the side of the bracket plate 6. One of the limiting circular plates 17 is fixedly connected to the output end of the drive motor 18. When the drive motor 18 is started, it will drive one of the limiting circular plates 17 to rotate. Since the two limiting circular plates 17 are rotatably connected to the inner sides of the two connecting blocks 5, the connecting blocks 5 will change their angle as the limiting circular plates 17 rotate, thereby initially adjusting the placement angle of the locomotive components.

[0037] Reference Figure 1 and Figure 3 The rotating assembly includes a second gear 21, which is rotatably connected to the inner side of the rotating housing 9. A first gear 20 is also rotatably connected to the inner side of the rotating housing 9, and the first gear 20 is rotatably connected to the outer side of the second gear 21. A fixed rod 19 is fixedly connected to the outer side of the second gear 21, and the fixed rod 19 is rotatably connected to the outer end of the rotating housing 9. A second drive motor 22 is fixedly connected to the outer side of the rotating housing 9, and the first gear 20 is fixedly connected to the output end of the second drive motor 22. Starting the second drive motor 22 causes the first gear 20 to rotate. The first gear 20 meshes with the second gear 21, so the rotation of the first gear 20 causes the second gear 21 to rotate. The fixed rod 19 is fixedly connected to the outer side of the second gear 21, so when the second gear 21 rotates, it causes the fixed rod 19 to rotate, thereby causing the connecting block 2 8 to rotate around the axis of the fixed rod 19. This allows for the horizontal adjustment of the locomotive parts, aligning the edges to be ground with the grinding disc 4. A protective outer shell 23 is fixedly connected to the outer side of the rotating housing 9. The protective outer shell 23 is fixedly connected to the outside of the drive motor 22. The protective outer shell 23 protects the drive motor 22 and prevents external debris, dust and other contaminants from entering the drive motor 22.

[0038] Reference Figure 1 and Figure 2 The clamping assembly includes a housing 10, which is fixedly connected to the outside of a limiting circular plate 17. A worm gear 11 is rotatably connected to the side of the housing 10, and a worm 12 is rotatably connected to the inner side of the end of the housing 10. The worm gear 11 is meshed with the outside of the worm 12. A connecting circular plate 13 is fixedly connected to the outside of the worm gear 11, and a spiral plate 14 is fixedly connected to the side of the connecting circular plate 13. Rotating the worm 12 will cause the worm gear 11 to rotate as well. The connecting circular plate 13 and the spiral plate 14 on the outside of the worm gear 11 will rotate together. When the connecting circular plate 13 rotates, the spiral plate 14 also rotates synchronously. The clamping assembly also includes multiple moving blocks 15, which are all rotatably connected to the outside of the spiral plate 14. Fixed blocks 16 are fixedly connected to the sides of each moving block 15. During the rotation of the spiral plate 14, the moving blocks 15 will move along the spiral trajectory of the spiral plate 14. The movement of the movable block 15 will cause the fixed block 16 to move. Multiple fixed blocks 16 move closer or further apart from each other, ultimately clamping the locomotive parts firmly between the two connecting blocks 15.

[0039] Reference Figure 1 and Figure 5The spacing adjustment assembly also includes multiple electric push rods 7, which are fixedly connected to the inner sides of both ends of the connecting block 8. Each of the other ends of the electric push rods 7 is fixedly connected to a slider 28, which is fixedly connected to the bottom sides of two connecting blocks 5. Activating the electric push rods 7 on the inner sides of both ends of the connecting block 8 moves the connected sliders 28. This allows the two connecting blocks 5 to slide on the connecting block 8, thereby adjusting the spacing between the two connecting blocks 5 to accommodate locomotive parts of different sizes.

[0040] Reference Figure 1 and Figure 4 The grinding assembly also includes an electric push rod 24, which is fixedly connected to the outside of the connecting plate 2. A telescopic housing 3 is located on the outside of the electric push rod 24. When the drive motor 25 is activated, it drives the grinding disc 4 to rotate at high speed, grinding the edges and corners of the locomotive parts. The extension and retraction of the electric push rod 24 on the outside of the connecting plate 2 pushes the connected telescopic housing 3 to move. One end of the telescopic housing 3 is fixedly connected to the side of the connecting plate 2, and the other end is fixedly connected to the drive motor 25. The grinding disc 4 is fixedly connected to the output end of the drive motor 25. When the electric push rod 24 pushes the telescopic housing 3, it can adjust the distance between the grinding disc 4 and the locomotive parts to meet different grinding requirements.

[0041] Reference Figure 4 and Figure 6 Both sides of the connecting plate 2 are fixedly connected with slot blocks 26, and the inner sides of the two slot blocks 26 are slidably connected with locking blocks 27. Each end of the locking blocks 27 is provided with a fixing bolt 29, which is located on the inner side of the base plate 1. The slot blocks 26 and locking blocks 27 on both sides of the connecting plate 2 are slidably engaged. After the operator adjusts the position of the locking blocks 27 within the slot blocks 26, the locking blocks 27 are fixedly connected to the base plate 1 using the fixing bolts 29, thereby stably installing the connecting plate 2 on the base plate 1 and ensuring the stability of the entire grinding equipment during operation.

[0042] Working principle: First, start the electric push rod 7 on the inner side of both ends of the connecting block 28. The electric push rod 7 pushes the slider 28, which in turn drives the two connecting blocks 15 to slide on the outside of the connecting block 28, adjusting the distance between the two connecting blocks 15 to accommodate locomotive parts of different sizes.

[0043] The worm gear 12 is connected to an external device for rotation. Since the worm gear 12 meshes with the worm wheel 11, it drives the worm wheel 11 to rotate. At the same time, the circular plate 13 also rotates with the worm wheel 11, and the spiral plate 14 connected to the side of the circular plate 13 also rotates together. The movable block 15 on the outer side of the spiral plate 14 moves along its surface under the action of the spiral plate 14. The fixed block 16 on the side of the movable block 15 moves closer or further away, thereby clamping and fixing the parts between the two connecting blocks 15.

[0044] After the parts are clamped and fixed, start the drive motor 18 to drive one of the limiting circular plates 17 to rotate. Since the two limiting circular plates 17 are respectively rotatably connected to the inner side of the two connecting blocks 5, the connecting blocks 5 and the parts connected to them can rotate around the axis of the limiting circular plates 17 to achieve the initial adjustment of the part angle.

[0045] After the component angles are adjusted, the electric push rod 24 on the outside of the connecting plate 2 is activated to push the telescopic shell 3, so that the drive motor 25 and the grinding disc 4 at the end of the telescopic shell 3 move closer to or further away from the component, and the distance between the grinding disc 4 and the component is adjusted to adapt to different grinding needs.

[0046] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
