Description

Technical Field

[0001] This utility model relates to the field of bearing processing clamping technology, and in particular to a clamping structure for processing bearing accessories. Background Technology

[0002] In the field of mechanical manufacturing, the processing quality of bearing components plays a crucial role in the performance and service life of the entire bearing. During the processing of bearing components, the clamping structure is one of the key elements to ensure processing accuracy and efficiency. With the increasing precision requirements of modern industry for bearing products and the emergence of diversified processing technology demands, traditional bearing component processing clamping structures are gradually becoming unable to meet the needs of actual production in many aspects. Furthermore, in order to adapt to the requirements of mass production and complex processing procedures, the clamping structure must also have the characteristics of efficient clamping, convenient disassembly, and good compatibility with various processing equipment. Against this background, an innovative bearing component processing clamping structure is particularly necessary. It is expected to overcome many shortcomings of existing technologies, better serve the bearing component processing industry, and improve the overall production quality and efficiency.

[0003] Currently, the most commonly used clamping structures in bearing component processing are external clamping mechanical structures. These structures typically consist of a fixed base, two or more rigid clamping arms, and a fastening device. The technical principle is to place the bearing component on the base and rotate the fastening device manually or with the aid of tools to move the clamping arms radially, thereby clamping the bearing component from the outside. For example, the common three-jaw chuck is a typical external clamping structure. It has a flat threaded disc inside, which is connected to the three jaws by threads. When the chuck wrench is turned, the flat threaded disc rotates, causing the three jaws to move radially in a synchronized extension and retraction motion, thereby clamping the bearing component.

[0004] However, existing external clamping structures, which clamp bearing components from the outside, are easily affected by the shape errors of the components themselves and human factors during clamping operations. It is difficult to ensure that the center of the bearing component coincides with the rotation center of the machining equipment. When machining bearing components with high precision requirements, especially the internal diameter, this error will further lead to the inability to meet the ideal standards for the cylindricity, coaxiality, and other geometric tolerances of the machined inner hole, thus affecting the overall quality of the bearing component and failing to meet the stringent requirements of modern industry for high-precision bearing products. Therefore, a clamping structure for machining bearing components is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a clamping structure for processing bearing parts, aiming to improve the problem that the traditional external clamping structure in the prior art is often difficult to accurately position when clamping bearing parts, so that the center of the bearing parts cannot be well aligned with the rotation center of the processing equipment.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A clamping structure for machining bearing parts includes a support frame with slots inside, and a clamping assembly on the top of the support frame for clamping the workpiece to be machined.

[0008] The clamping assembly includes a fixed frame, which is fixedly connected to the top of the support frame. A motor is fixedly connected inside the fixed frame, and a rotating disk is fixedly connected to the output end of the motor. A limit groove is formed inside the rotating disk, and a transmission column is slidably connected inside the limit groove. A clamping plate is fixedly connected to the outer wall of the transmission column, and a slider is fixedly connected to the bottom of the clamping plate. A slide rail is slidably connected inside the slider, and the bottom of the slide rail is fixedly connected to the upper surface of the fixed frame. A disassembly assembly is provided inside the fixed frame to facilitate maintenance of the clamp by the user.

[0009] As a further description of the above technical solution:

[0010] The disassembly assembly includes a connecting column and a handle. The outer wall of the connecting column is fixedly connected to the inside of the fixing frame, and the outer wall of the handle slides inside the connecting column.

[0011] As a further description of the above technical solution:

[0012] A sliding post is fixedly connected to one end of the handle, and a collar is fixedly connected to the outer wall of the sliding post;

[0013] As a further description of the above technical solution:

[0014] A fixing ring is slidably connected to the outer wall of the sliding column, and the fixing ring is fixedly connected to the inner wall of the connecting column;

[0015] As a further description of the above technical solution:

[0016] The sliding column has internal threads, and the threads are rotatably connected to the connecting column;

[0017] As a further description of the above technical solution:

[0018] The bottom end of the sliding column is fixedly connected to a connecting shaft, and one end of the connecting shaft is fixedly connected to a conical block;

[0019] As a further description of the above technical solution:

[0020] The outer wall of the conical block is slidably connected to a limiting ball, and a tray is fixedly connected to the bottom end of the conical block.

[0021] This utility model has the following beneficial effects:

[0022] In this invention, a motor drives a rotating disk to rotate, which in turn drives a transmission column to move synchronously. The movement of the transmission column causes the slider to slide on the outer wall of the slide rail, thereby causing multiple clamping plates to press inward synchronously. This achieves rapid clamping and precise centering, solving the problem that traditional equipment often relies on the operator's experience and the limited centering function of the chuck itself to ensure that the center of the bearing parts coincides with the rotation center of the processing equipment. This improves the equipment's working efficiency and processing accuracy.

[0023] In this invention, rotating the handle causes the sliding column to slide inside the connecting column, which in turn drives the conical block to move up and down. Under the pressure of the conical block, the limiting ball is inserted into the slot, thus achieving the effect of quick disassembly and installation. This solves the problem that traditional equipment cannot be quickly disassembled when maintaining and replacing fixtures, and improves the flexibility and maintenance efficiency of the equipment.

[0030] 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.

[0031] Reference Figure 1 - Figure 3 The present invention provides an embodiment of a clamping structure for processing bearing accessories, including a support frame 1 for providing stable support, a slot 2 inside the support frame 1 for cooperating with a limiting ball 19 to achieve fixing and disassembly, and a clamping assembly on the top of the support frame 1 for clamping the workpiece to be processed.

[0032] The clamping assembly includes a fixed frame 3, which is fixedly connected to the top of the support frame 1. A motor 4 is fixedly connected inside the fixed frame 3. The motor 4 is the driving component, which drives the rotation of the rotating disk 5 through its output end. The output end of the motor 4 is fixedly connected to the rotating disk 5. A limit groove 6 is opened inside the rotating disk 5. The function of the limit groove 6 is to guide and limit the movement trajectory of the transmission column 7, ensuring that it works within a specific range. The transmission column 7 is slidably connected inside the limit groove 6. The function of the transmission column 7 is to further transmit power, thereby driving the movement of the clamping plate 8. The clamping plate 8 is fixedly connected to the outer wall of the transmission column 7 for clamping and fixing the workpiece to be processed. A slider 9 is fixedly connected to the bottom of the clamping plate 8. A slide rail 10 is slidably connected inside the slider 9. The slider 9 slides freely in the slide rail 10 to ensure that the clamping action of the clamping plate 8 can be accurately executed. The bottom of the slide rail 10 is fixedly connected to the upper surface of the fixed frame 3. A disassembly assembly is provided inside the fixed frame 3. The disassembly assembly is used to facilitate the maintenance of the fixture by the user.

[0033] Specifically, when clamping and limiting the workpiece to be processed, the operator places the workpiece on the surface of the rotating disk 5. The motor 4 drives the rotating disk 5 to rotate through its output end, so that the rotating disk 5 rotates with the operation of the motor 4. At the same time, the limiting groove 6 opened inside the rotating disk 5 also moves. The movement path of the limiting groove 6 is synchronized with the rotation of the rotating disk 5. When the limiting groove 6 starts to move, it drives the transmission column 7 to slide along the predetermined track, ensuring that the sliding process of the transmission column 7 is stable and smooth. The sliding action of the transmission column 7 further causes the clamping plates 8 to move synchronously. These clamping plates 8 cooperate with each other and rely on the thrust of the transmission column 7 to gradually squeeze inward. The movement of the clamping plates 8 not only pushes the slider 9, but also generates a greater inward clamping force by sliding the slider 9 along the outer wall of the slide rail 10. The clamping plates 8 firmly fix the workpiece in the designated position, ensuring that the workpiece will not move during the processing, thereby avoiding processing errors. This not only improves the processing accuracy, but also improves the working efficiency of the entire equipment, so that the workpiece remains in a stable state during the processing, ensuring the smooth progress of production.

[0034] Reference Figure 4 The disassembly assembly includes a connecting column 11 and a handle 12. The outer wall of the connecting column 11 is fixedly connected to the inside of the fixing frame 3. The outer wall of the handle 12 slides inside the connecting column 11. The handle 12 achieves smooth longitudinal movement through the sliding engagement between its outer wall and the inside of the connecting column 11. One end of the handle 12 is fixedly connected to a sliding column 13. The function of the sliding column 13 is to provide a wider range of motion support and sliding stability, so that the handle 12 can move smoothly within a predetermined trajectory. A collar 14 is fixedly connected to the outer wall of the sliding column 13, and a fixing ring 15 is slidably connected to the outer wall of the sliding column 13. The fixing ring 15 is fixedly connected to the inner wall of the connecting column 11.

[0035] Specifically, the processing equipment needs to be regularly maintained, serviced, and debugged to ensure it is in good operating condition and continuously produces high-quality bearing parts. When the operator turns the handle 12, the handle 12 will further drive the sliding column 13 to rotate along a predetermined track inside the connecting column 11. The movement of the sliding column 13 causes the collar 14 connected to it to move synchronously. Under the action of the collar 14, the thread 16 is forced to move along the predetermined trajectory, ensuring the stability and reliability of the system.

[0036] Reference Figure 4The sliding column 13 has a thread 16 inside, which is rotatably connected to the connecting column 11. The fixing ring 15 is tightly engaged with the end of the sliding column 13 by a fastening device to ensure that the thread 16 will not shift during operation. The bottom end of the sliding column 13 is fixedly connected to the connecting shaft 17. The connecting shaft 17 takes into account rotation and linear load to ensure that it can withstand axial and radial stress. One end of the connecting shaft 17 is fixedly connected to a tapered block 18. The surface of the tapered block 18 is processed to have a certain taper, so that the fit with the limiting ball 19 is tighter and more stable. The limiting ball 19 is slidably connected to the outer wall of the tapered block 18. The bottom end of the tapered block 18 is fixedly connected to the tray 20.

[0037] Specifically, at the same time, the downward movement of the sliding column 13 not only causes the collar 14 to move, but also drives the connecting shaft 17 and the conical block 18 to move downward synchronously. The conical block 18 has a unique geometric shape, with one end having a relatively large area and the other end having a relatively small area. During the downward pressing of the conical block 18, the larger end first contacts and gradually squeezes the limiting ball 19, forcing the limiting ball 19 into the groove 2. Due to the design principle of the conical block 18, as the conical block 18 is further pressed down, the limiting ball 19 is tightly stuck in the groove 2, thus forming a solid fixed structure. When the equipment needs maintenance or fixture replacement, the operator can easily release the fixation, making it convenient and quick to replace and adjust. This achieves an efficient and convenient fixture replacement process, while also enhancing the stability and reliability of the equipment during operation and improving the safety and accuracy of operation.

[0038] Working principle: When using this device, the operator places the workpiece to be processed on the surface of the rotating disk 5. The output of the motor 4 drives the rotating disk 5 to rotate. As the rotating disk 5 rotates, the limiting groove 6 inside it also moves synchronously. During the movement of the limiting groove 6, the transmission column 7 is further driven to slide along its track. The sliding of the transmission column 7 further drives the clamping plate 8 to move synchronously. The movement of the clamping plate 8 forces the slider 9 to slide on the outer wall of the slide rail 10, thereby causing multiple clamping plates 8 to press inwards synchronously, effectively fixing the workpiece. When the equipment needs to be replaced or the clamping needs to be adjusted, the device can be used to fix the workpiece. When the component is being maintained, the operator can turn the handle 12. As the operator turns the handle, the sliding column 13 will rotate inside the connecting column 11 and move downwards, which will further drive the collar 14 to move synchronously, thereby stably driving the connecting shaft 17 and the conical block 18 to move. Due to the special shape of the conical block 18, one end of its area is relatively large and the other end is relatively small. When the conical block 18 moves downwards, the larger end will gradually squeeze the limiting ball 19, causing it to be stuck inside the slot 2, thereby achieving a fixing effect. This makes it convenient for the user to operate when maintenance and fixture replacement are required.

[0039] 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.
