Description

Technical Field

[0001] This utility model relates to the field of centerless grinding machine technology, and in particular to a support device that can increase the grinding length of a centerless grinding machine. Background Technology

[0002] Centerless grinders, which do not require workpiece axis positioning, possess advantages such as high production efficiency, high machining accuracy, and good surface quality due to their working principle of working in cooperation with the grinding wheel, adjusting wheel, and support. They are widely used in the fields of automobile manufacturing, aerospace, electronic equipment manufacturing, and general machinery manufacturing to process various shafts, pins, and other parts. In the practical application of centerless grinders, the support device that can increase the grinding length is crucial, as it can adapt to diverse workpiece processing needs, ensure machining accuracy and quality, improve production efficiency, and reduce production costs.

[0003] A support device that can increase the grinding length of a centerless grinder generally consists of a basic support structure, an adjustable support body, a positioning and locking device, auxiliary support and protective components, etc. The support device that can increase the grinding length of a centerless grinder can achieve length adjustment through lead screws and nuts, hydraulic or pneumatic means, and use positioning pins and positioning holes, locking bolts or clamping mechanisms for positioning and locking. The workpiece is supported by the support body and auxiliary support rollers. With the help of manual or automatic control and feedback, it can meet the support requirements of workpieces of different lengths and ensure efficient and precise machining of the centerless grinder.

[0004] Existing support devices for increasing the grinding length of centerless grinders cannot quickly adapt to objects of different lengths. In actual production, if workpieces of various lengths need to be processed, the support device cannot adapt quickly each time the workpiece length is changed. This requires operators to spend a lot of time on complex adjustments, repeatedly disassembling and installing components, or making multiple fine adjustments to the positioning device. This significantly increases the idle time of the equipment, slows down the overall production pace, and significantly reduces production efficiency. Therefore, a support device that can increase the grinding length of centerless grinders is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a support device that can increase the grinding length of a centerless grinder, aiming to improve the problem that the prior art cannot quickly adapt to objects of different lengths.

[0031] 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.

[0032] Reference Figures 1 to 3 One embodiment of this utility model is a support device that can increase the grinding length of a centerless grinder, including a base plate 1. The base plate 1 is like the foundation of the entire support device, providing a stable support plane for all subsequent components, ensuring that the device will not shake due to an unstable foundation during operation, thus affecting the machining accuracy.

[0033] A mounting slide rail 2 is fixedly connected to the top of the base plate 1. The mounting slide rail 2 provides precise guidance for the movement of the sliding block 3, so that the sliding block 3 can slide smoothly along the preset trajectory, ensuring the positional accuracy of the bracket device during the adjustment process. An electric slide rail 7 is fixedly connected to the top of the base plate 1. As a power drive part, the electric slide rail 7 can precisely control the moving distance and speed of the slider 8, thereby realizing the precise adjustment of the extension length of the bracket device and meeting the grinding requirements of workpieces of different lengths.

[0034] The electric slide rail 7 has a slider 8 internally connected. Driven by the electric slide rail 7, the slider 8 can slide smoothly within its track, driving the connecting plate 9 connected to it to move, thereby realizing the transmission of the expansion action of the entire bracket device. The top of the slider 8 is rotatably connected to two connecting plates 9, which play the role of connection and transmission, converting the linear motion of the slider 8 into a motion form suitable for the sliding block 3, while ensuring the effective transmission of force during the movement and ensuring the stable operation of the device.

[0035] Two connecting plates 9 are rotatably connected to sliding blocks 3 at their ends away from the slider 8. Under the drive of the connecting plates 9, the sliding blocks 3 slide along the trajectory of the mounting slide rail 2, realizing the adjustment of the bracket device in the length direction and providing position adjustment function for the connecting device 4 and subsequent components. The outer side of the sliding block 3 is slidably connected to the inside of the mounting slide rail 2. This tight and smooth sliding connection method not only ensures the stability of the movement of the sliding block 3, but also allows the mounting slide rail 2 to precisely constrain the position of the sliding block 3, ensuring the accuracy of the entire device during the adjustment process.

[0036] A connecting device 4 is fixedly connected to the top of the sliding block 3. The connecting device 4 securely connects the sliding block 3 and the rotating bracket 5 together, making the entire bracket device an organic whole. This ensures that all components work together to support the workpiece during operation. Rotating brackets 5 are rotatably connected to both sides of the connecting device 4. The rotating brackets 5 can flexibly adjust their angles according to the shape of the workpiece and the requirements of the grinding process, providing the best support angle for different types of workpieces and ensuring that the workpiece remains stable during grinding. A support plate 6 is fixedly connected to the top of the rotating bracket 5. The support plate 6 directly contacts the workpiece, providing a reliable support surface for the workpiece, enabling the workpiece to withstand the grinding force during grinding and ensuring the smooth progress of the grinding process. Mounting components for mounting the base plate 1 are fixedly connected to both sides of the base plate 1.

[0037] Reference Figure 1 , Figure 2 , Figure 4 The mounting assembly includes a limiting plate 10 with holes inside. These holes are used to mate with parts to realize the function of the mounting assembly and ensure a stable connection between the entire device and external equipment. The inner side of the limiting plate 10 is fixedly connected to both sides of the base plate 1, tightly connecting the mounting assembly to the base plate 1 and providing a foundation for subsequent installation operations. The inner side of the limiting plate 10 is slidably connected to a housing 11, which can slide inside the limiting plate 10 to facilitate position adjustment during installation and disassembly.

[0038] A sliding rod 12 is slidably connected inside the housing 11. The sliding rod 12 slides inside the housing 11, and its movement triggers the action of related components to realize the installation and disassembly of the device. A second spring 15 is fixedly connected to the bottom of the sliding rod 12. The second spring 15 provides a restoring elastic force for the sliding rod 12, so that the sliding rod 12 can automatically return to the initial position after the operation is completed, which is convenient for the next operation. The other end of the second spring 15 is fixedly connected inside the housing 11, providing fixed support for the second spring 15 and ensuring the stability of its elastic force.

[0039] A sliding column 16 is fixedly connected to the bottom of the sliding rod 12. The sliding column 16 slides inside the housing 11, serving as a guide to ensure the smooth and accurate movement of the sliding rod 12. A rotating plate 14 is rotatably connected inside the sliding rod 12. The rotating plate 14 rotates inside the sliding rod 12, and its rotation enables it to cooperate with the parts, completing the locking and unlocking functions and ensuring the installation of the device firmly. The outer side of the rotating plate 14 is slidably connected to the inside of the housing 11. The sliding inside the housing 11 provides space for the movement of the rotating plate 14. The other end of the rotating plate 14 is fixedly connected to the inside of the sliding rod 12 to ensure the stability of the rotating plate 14 when it rotates inside the sliding rod 12.

[0040] A spring 13 is fixedly connected to one end of the rotating plate 14. The spring 13 provides the power for the rotating plate 14 to pop out and retract, so that it can complete the locking or unlocking action at the appropriate time. The outer side of the rotating plate 14 is slidably connected to the inside of the limiting plate 10. Through the coordinated work of the parts inside the limiting plate 10, a limiting ring 17 is fixedly connected to the outer side of the housing 11. The limiting ring 17 restricts the position of the relevant parts to ensure the stability of the device during installation and use. The bottom of the limiting ring 17 is slidably connected to the top of the limiting plate 10 to ensure that the connection between the limiting ring 17 and the limiting plate 10 is tight and can slide relative to each other to realize its limiting function.

[0041] Working principle: When the operator needs to use the bracket device, they can place the base plate 1 in the designated position. Both sides of the base plate 1 are connected to limiting plates 10. A housing 11 slides inside the limiting plates 10. Because the limiting plates 10 have holes inside, a hole needs to be made at the designated position corresponding to the hole inside the limiting plates 10 to facilitate the sliding of the housing 11. Once the hole is made, the housing 11 can be slid into the hole. The sliding of the housing 11 is achieved using multiple rotating plates 14. When a rotating plate 14 just contacts the inner wall of the limiting plate 10, it is squeezed back into the housing 11 by the inner wall of the limiting plate 10. When the spring 13 passes through the interior of the limiting plate 10 and reaches the designated position, it is compressed and spring-loaded. Spring 13 pushes out of the interior of spring 13 and enters the interior of the hole. At this time, the outer shell 11 is restricted by the cooperation of rotating plate 14 and limiting ring 17. When it is necessary to move the position of the bracket device, the sliding rod 12 can be pressed to make the sliding rod 12 slide downward. Multiple rotating plates 14 rotate inside the sliding rod 12, so when the sliding rod 12 slides downward, it will also drive the rotating plates 14. At this time, the rotating plates 14 will be squeezed by the inner wall of the outer shell 11, thereby compressing the rotating plates 14 back into the interior of the sliding rod 12. After the rotating plates 14 are fully retracted and the restriction of the outer shell 11 is removed, the outer shell 11 can be taken out from the interior of the limiting plate 10, thereby realizing the installation or disassembly of the bracket device.

[0042] When the object to be ground is too long, the electric slide rail 7 can be activated, which will drive the slider 8. The slider 8 will then drive the two connecting plates 9 connected to the top. The other end of the connecting plate 9 is connected to the outside of the sliding block 3. Under normal circumstances, the connecting plate 9 is tilted. When the slider 8 is activated, it will straighten the connecting plate 9, thereby pushing the sliding block 3 out. The top of the sliding block 3 is connected to the connecting device 4. This allows the connecting devices 4 on both sides to be pushed by the connecting plate 9 and slide outward, thereby achieving the effect of expanding the bracket device.

[0043] 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.
