Description

Technical Field

[0001] This utility model relates to the field of parts grinding technology, and in particular to a grinding device for mechanical parts. Background Technology

[0002] In the field of machining, the grinding of tubular parts requires extremely high precision and stability. However, existing grinding equipment has many technical pain points in practical applications.

[0003] Traditional grinding equipment relies heavily on manual calibration for positioning tubular parts, which is not only inefficient but also prone to uneven grinding and dimensional inaccuracies due to human error causing the part's center to misalign with the grinding tool. Furthermore, clamping mechanisms often employ single-direction or symmetrical two-point clamping methods, making it difficult to generate uniform and stable clamping force for tubular parts of different diameters. During grinding, parts are prone to radial or axial displacement, affecting grinding quality and posing safety hazards. Moreover, the positioning and clamping functions of most equipment are independent and lack coordination, leading to secondary deviations after positioning and making it difficult to flexibly adapt to the processing needs of various tubular parts. Therefore, this application provides a mechanical parts grinding device to meet these requirements. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a grinding device for mechanical parts, which solves the problems mentioned in the background art.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0006] A grinding device for mechanical parts includes a processing table, a fixed base fixedly connected to the top of the processing table, support plates fixedly connected to both sides of the top of the processing table, a lifting plate slidably connected to the inner side of the support plates, a clamping assembly for fixing and clamping a tubular part, the clamping assembly being connected to the fixed base, and a positioning assembly for centering the tubular part, the positioning assembly being connected to the processing table.

[0007] Optionally, the clamping assembly includes a clamping disk fixedly connected to the inner side of the circular base. A sliding groove is provided on the inner side of the clamping disk, and a clamping block is slidably connected to the inner side of the sliding groove. Pushing rings are provided on the upper and lower sides of the clamping disk, and a sloping groove is provided on the outer side of the pushing ring. The outer cylinder of the clamping block is slidably connected to the inner side of the sloping groove.

[0008] Optionally, a guide block is fixedly connected to the outside of the clamping disc, and a guide groove is provided on the outside of the pushing ring, with the inner side of the guide groove slidably connected to the guide block.

[0009] Optionally, a threaded rotating rod A is rotatably connected to the inner side of the rectangular fixed base, and a movable frame is threadedly connected to the outer side of the threaded rotating rod A. The movable frame and the push ring are rotatably connected by a connecting rod.

[0010] Optionally, the positioning assembly includes a fixed cylinder fixedly connected to the top of the processing table, a threaded screw rotatably connected to the inner side of the fixed cylinder, a movable ring threadedly connected to one end of the threaded screw, a fixed ring fixedly connected to one end of the fixed cylinder, and the fixed ring and the movable ring rotatably connected through an X-shaped rotating frame, and an arc-shaped plate rotatably connected to the outer side of the X-shaped rotating frame.

[0011] Optionally, a servo motor is fixedly connected to the bottom of the processing table, and a threaded screw extends to one end of the bottom of the processing table and is fixedly connected to the output end of the servo motor.

[0012] Optionally, a threaded rotating rod B is rotatably connected to the inner side of the support plate, and the threaded rotating rod B is threadedly connected to the lifting plate. A drive motor is fixedly connected to the top of the lifting plate, and the output end of the drive motor passes through to a grinding sleeve fixedly connected to one end of the outer side of the lifting plate.

[0013] Beneficial effects:

[0014] In the above scheme, by setting up a clamping assembly, rotating the threaded rod A drives the moving frame to move, and the connecting rod pushes two sets of pushing rings to slide smoothly along the guide block. The inclined groove of the pushing ring, through its cooperation with the outer cylinder of the clamping block, converts the horizontal movement into the synchronous radial movement of the clamping block along the sliding groove. This allows multiple clamping blocks to form a uniform clamping force on the tubular part from all sides, and the clamping surface is in close contact with the surface of the part, avoiding the risk of displacement of the part during the grinding process. This not only improves the accuracy and firmness of the clamping, but also simplifies the operation process through mechanical transmission, effectively ensuring the precision and safety of the grinding process.

[0015] By setting up a positioning component, a servo motor drives the threaded screw to rotate, causing the movable ring to move closer to the fixed ring, thus reducing the angle of the X-shaped rotating frame. This pushes the arc plate to open and initially fix the inner bottom of the tubular part. The opening range can be flexibly adjusted according to the diameter of the part, adapting to the grinding needs of tubular parts of various sizes. Moreover, the positioning component precisely centers the part in the grinding center, providing a precise reference for subsequent clamping actions, reducing grinding errors caused by positioning deviations from the source, ensuring the concentricity of the grinding sleeve and the part, and significantly improving the stability and processing quality of the grinding process.

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.

[0024] like Figure 1 and Figure 3As shown, an embodiment of this utility model provides a mechanical parts grinding device, including a processing table 1. The processing table 1 is characterized by having a fixed base 2 fixedly connected to its top, support plates 5 fixedly connected to both sides of the top of the processing table 1, a lifting plate 7 slidably connected to the inner side of the support plates 5, a clamping assembly 3 for fixing and clamping tubular parts, the clamping assembly 3 being connected to the fixed base 2, a positioning assembly 4 for centering the tubular parts, the positioning assembly 4 being connected to the processing table 1, a threaded rotating rod B6 rotatably connected to the inner side of the support plates 5, and the threaded rotating rod B6 being threadedly connected to the lifting plate 7, a drive motor 8 fixedly connected to the top of the lifting plate 7, and the output end of the drive motor 8 extending through to the outer side of the lifting plate 7. The end is fixedly connected to a grinding sleeve 9. This application provides a grinding device for mechanical parts. It can not only use multiple clamping blocks 303 to form a uniform clamping force on the tubular part from all sides through the clamping assembly 3, which is in close contact with the surface of the tubular part, reducing the risk of displacement during processing, but also improve the accuracy and firmness of clamping, simplify the operation process, and ensure the precision and safety of grinding processing. In addition, the positioning assembly 4 can be used to adjust the fixing range according to the size of the tubular part, form a stable support for the tubular part from below, and complete the initial positioning. It can adapt to the grinding needs of tubular parts with different diameters. At the same time, the initial positioning provides a reference for subsequent clamping actions, reduces grinding processing errors caused by positioning deviations, and ensures the stability of the grinding process.

[0025] In this embodiment, as Figures 2 to 5As shown, the clamping assembly 3 includes a clamping disk 301 fixedly connected to the inner circular side of the fixed base 2. A sliding groove 302 is provided on the inner side of the clamping disk 301, and a clamping block 303 is slidably connected to the inner side of the sliding groove 302. Pushing rings 304 are provided on the upper and lower sides of the clamping disk 301. An inclined groove 305 is provided on the outer side of the pushing ring 304, and the outer cylinder of the clamping block 303 is slidably connected to the inner side of the inclined groove 305. A guide block 307 is fixedly connected to the outer side of the clamping disk 301. A guide groove 306 is provided on the outer side of the pushing ring 304, and the inner side of the guide groove 306 is slidably connected to the guide block 307. A threaded rotating rod A308 is rotatably connected to the inner rectangular side of the fixed base 2. A movable frame 309 is threadedly connected to the outer side of the threaded rotating rod A308. The movable frame 309 and the pushing ring 304 are rotatably connected via a connecting rod 310. When the position of the tubular part is initially fixed, the threaded rotating rod A308 is rotated. 8. The moving frame 309 is moved along the inner side of the fixed base 2, thereby using the connecting rod 310 to push the guide grooves 306 on the surface of the two sets of pushing rings 304 to rotate along the guide block 307, so that the inclined groove 305 pushes multiple sets of clamping blocks 303 to move along the sliding groove 302, and at the same time squeezes the parts inside the clamping plate 301, thereby achieving clamping and fixing of the tubular parts inside the clamping plate 301, forming a uniform clamping force in the circumferential direction of the tubular parts, and closely fitting the surface of the tubular parts, reducing the risk of displacement during processing, which not only improves the accuracy and firmness of clamping, but also simplifies the operation process, and ensures the precision and safety of grinding processing. Afterwards, the threaded rotating rod B6 is rotated to drive the lifting plate 7 to move down, so that the inner side of the grinding sleeve 9 fits with the tubular parts, and the drive motor 8 is turned on to drive the grinding sleeve 9 to rotate, completing the grinding processing of the tubular parts inside the grinding sleeve 9.

[0026] In this embodiment, as Figures 3 to 6As shown, the positioning assembly 4 includes a fixed cylinder 401 fixedly connected to the top of the processing table 1. A threaded screw 402 is rotatably connected to the inner side of the fixed cylinder 401. A movable ring 404 is threadedly connected to one end of the threaded screw 402. A fixed ring 403 is fixedly connected to one end of the fixed cylinder 401, and the fixed ring 403 and the movable ring 404 are rotatably connected through an X-shaped rotating frame 405. An arc-shaped plate 406 is rotatably connected to the outer side of the X-shaped rotating frame 405. A servo motor 407 is fixedly connected to the bottom of the processing table 1, and the threaded screw 402 extends to the bottom of the processing table 1 and is fixedly connected to the output end of the servo motor 407. In use, the tubular part is placed... Inside the clamping plate 301, the servo motor 407 is turned on, causing the servo motor 407 to drive the threaded screw 402 to rotate along the inside of the fixed cylinder 401. When the threaded screw 402 rotates, it drives the movable ring 404 to move along the thread and approach the fixed ring 403, causing the angle of the X-shaped rotating frame 405 to decrease. This allows the arc plate 406 to open and initially fix the inner bottom of the tubular part, while ensuring that the part is always in the center of the grinding process. This adapts to the grinding needs of tubular parts of different diameters. At the same time, the initial positioning provides a reference for subsequent clamping actions, reducing grinding errors caused by positioning deviations and ensuring the stability of the grinding process.

[0027] The working principle of the technical solution provided by this utility model is as follows: In use, the tubular part is placed inside the clamping plate 301, and the servo motor 407 is turned on, causing the servo motor 407 to drive the threaded screw 402 to rotate along the inner side of the fixed cylinder 401. When the threaded screw 402 rotates, it drives the movable ring 404 to move along the thread and approach the fixed ring 403, causing the angle of the X-shaped rotating frame 405 to decrease. This allows the arc plate 406 to open and initially fix the inner bottom of the tubular part, while ensuring that the part is always at the center of the grinding process. This adapts to the grinding needs of tubular parts of different diameters. The initial positioning provides a reference for subsequent clamping actions, reducing grinding errors caused by positioning deviations and ensuring the stability of the grinding process. When the tubular part is initially fixed, the threaded rotating rod A308 is rotated, driving the moving frame 309... Moving along the inner side of the fixed base 2, the connecting rod 310 pushes the guide grooves 306 on the surface of the two sets of push rings 304 to rotate along the guide block 307, so that the inclined groove 305 pushes multiple sets of clamping blocks 303 along the sliding groove 302, and simultaneously squeezes the part inside the clamping plate 301, thereby achieving clamping and fixing of the tubular part inside the clamping plate 301, forming a uniform clamping force on the tubular part from all sides, and closely fitting the surface of the tubular part, reducing the risk of displacement during processing, improving the accuracy and firmness of clamping, simplifying the operation process, and ensuring the precision and safety of grinding. Afterwards, rotating the threaded rotating rod B6 drives the lifting plate 7 to move down, so that the inner side of the grinding sleeve 9 fits with the tubular part, and turning on the drive motor 8 drives the grinding sleeve 9 to rotate, completing the grinding of the tubular part inside the grinding sleeve 9.
