Abstract
Description
Technical Field
[0001] The embodiments disclosed herein relate to the technical field of bar processing equipment, specifically to a dustproof feeding device for a centerless grinding machine used for processing precision bars of special steel. Background Technology
[0002] In the field of machining precision bars of special steel, centerless lathes are crucial processing equipment. In actual production, special steel bars easily accumulate large amounts of dust, debris, and other foreign matter on their surface during storage and transportation. If these bars are directly placed into a centerless lathe for machining without cleaning, numerous problems will arise.
[0003] On the one hand, dust and other foreign objects can enter the contact area between the cutting tool and the bar stock during machining, affecting the cutting accuracy of the tool and causing dimensional deviations in the machined bar stock, making it difficult to meet the requirements of precision machining. On the other hand, these foreign objects may also scratch the surface of the bar stock during machining, reducing the surface quality of the bar stock and affecting the final performance and appearance of the product.
[0004] Furthermore, as processing continues, a large amount of dust accumulates inside the lathe, accelerating the wear of lathe parts, increasing the probability of equipment failure, shortening equipment lifespan, and raising maintenance costs. Therefore, developing a dustproof feeding device for a centerless grinding machine used for machining precision steel bars is of great significance. It can effectively clean foreign objects from the surface of the bars, ensure machining accuracy, and extend equipment lifespan. Utility Model Content

[0037] like Figures 1-5 As shown, it illustrates a dustproof feeding device for a centerless grinding machine for machining precision steel bars according to an embodiment of this disclosure, comprising:
[0038] A base 1 and a pair of brackets 2, the brackets 2 being fixed to each other and the brackets 2 being mounted on the base 1;
[0039] Angle adjustment component 5 is disposed between bracket 2 and base 1;
[0040] Conveying component 6 is mounted on bracket 2;
[0041] Vacuum cleaner 3 and cleaning component 4, the vacuum cleaner 3 is fixed to the bottom of bracket 2, and the cleaning component 4 is set on bracket 2;
[0042] The cleaning component 4 includes an annular cover 4-1, which is fixed to the surface of the bracket 2. A drive motor 4-2 is fixedly connected to the top of the annular cover 4-1. A rotating frame 4-3 is connected to the inside of the annular cover 4-1. A cleaning brush 4-4 is provided around the inner surface of the rotating frame 4-3. The surface of the annular cover 4-1 is hollow. A suction port 4-5 is provided around the inner surface of the annular cover 4-1. The suction end of the vacuum cleaner 3 is connected to the annular cover 4-1. A drive wheel 4-6 is provided at the output end of the drive motor 4-2. A transmission wheel 4-7 is provided around the surface of the rotating frame 4-3. The drive wheel 4-6 and the transmission wheel 4-7 are connected by a belt drive.
[0043] In some examples, a cleaning component 4 is designed to achieve the effect of cleaning the surface of the rod. This component includes a circular cover fixed to the bracket 2. The inner side of the hollow structure of the circular cover has a suction port 4-5. The suction port 4-5 can work with the vacuum cleaner 3 to generate suction. The suction port 4-5 and the inside of the circular cover form a channel to guide the sucked dust into the vacuum cleaner 3 for collection. It can collect the dust and foreign objects cleaned on the surface of the rod. The circular cover 4-1 is rotatably connected to a rotating frame 4-3, and a cleaning brush 4-4 is set around its inner surface. When the rotating frame 4-3 rotates, it can clean the surface of the rod through the cleaning brush 4-4. The output end of the drive motor 4-2 is provided with a drive wheel 4-6. The outer surface of the rotating frame 4-3 is provided with an external gear and is connected to the drive wheel 4-6 through belt drive. The drive can be used to power the rotating frame 4-3 to continuously rotate, thereby achieving the cleaning effect.
[0044] like Figures 1-5As shown, this embodiment proposes an angle adjustment component 5 including a fixed frame 5-1, which is disposed on the surface of the base 1. The bottom of the bracket 2 is rotatably connected to the upper end of the fixed frame 5-1 via a pin. A bottom groove 5-2 is provided on the surface of the base 1. A drive screw 5-3 is rotatably connected in the bottom groove 5-2. The drive screw 5-3 is rotated by a motor. A pair of slide rails 5-4 are provided at the bottom of the bottom groove 5-2. A movable seat 5-5 is slidably connected on the slide rails 5-4. The movable seat 5-5 is connected to the drive screw 5-3 by a threaded connection. A support rod 5-6 is rotatably connected to the surface of the movable seat 5-5 via a pin. A connecting frame 5-7 is provided at the upper end of the support rod 5-6. The connecting frame 5-7 is rotatably connected to the bottom of the bracket 2 via a pin.
[0045] In some examples, to achieve the effect of adjustable bracket 2 for easy insertion of bar stock, an angle adjustment component 5 is designed. This component includes a fixed frame 5-1 fixed to the surface of the base 1. The upper end of the fixed frame 5-1 is rotatably connected to the bottom of the bracket 2 by a pin. The bracket 2 can rotate through the pin connection with the fixed frame 5-1. A rectangular groove is opened at the other end of the surface of the base 1, and a drive screw 5-3 and a slide rail 5-4 are installed inside. A movable seat 5-5 is connected to the drive screw 5-3 and the slide rail 5-4. The movable seat 5-5 can be controlled to move linearly by the drive screw 5-3. The surface of the movable seat 5-5 is rotatably connected to the bottom of the connecting frame 5-7 by a pin. When the movable seat 5-5 is displaced, an angle change will occur during the movement. The bracket 2 tilts downward with the angle change of the support rod 5-6. In the tilted state, the worker can lift one end of the bar stock and put it into the bracket 2, so that there is no need for lifting equipment to assist in loading.
[0046] like Figures 1-4 As shown, this embodiment proposes a conveying component 6 including several rolling wheels 6-1, all of which are rotatably connected to the bracket 2. Several second motors 6-2 are provided at the bottom of the bracket 2, and transmission gears 6-3 are provided at the output end of the second motors 6-2 and at one end of the rotation shaft of the rolling wheels 6-1.
[0047] In some examples, a conveying assembly 6 is designed to achieve a stable, centered conveying effect on the bar stock. This assembly includes multiple rollers 6-1, all of which are rotatably connected within the bracket 2 and are evenly spaced to drive the bar stock. A second motor 6-2 is installed below some of the rollers 6-1, providing driving force for the conveying and enabling the rollers 6-1 to rotate actively. Both the output end of the second motor 6-2 and one end of the rotation shaft of the rollers 6-1 are equipped with transmission gears 6-3. Through the transmission of the transmission gears 6-3, the active rotation of the rollers 6-1 is controlled.
[0048] For example, such as Figure 1As shown, the bracket 2 has an inclined structural surface, and the rolling wheel 6-1 has a concave arc-shaped structural surface.
[0049] In some examples, the inclined structural surface facilitates the insertion of the bar, allowing it to fall directly onto the roller 6-1 and remain in a centered position.
[0050] For example, such as Figure 1 As shown, one end of bracket 2 can tilt downwards at 45°.
[0051] In some examples, by tilting downwards at a 45° angle, one end of the bracket 2 is brought as close to the ground as possible, which makes loading easier.
[0052] For example, such as Figure 1 As shown, the surfaces of the rolling wheels 6-1 are all anti-slip structural surfaces with high friction.
[0053] In some examples, the anti-slip effect between the structural surface with high friction can be increased, which makes it easier to bring the bar into the bracket 2 during active rotation.
[0054] In actual use: First, by adjusting the angle component 5, the motor is started to rotate the drive screw 5-3, which drives the moving seat 5-5 to move on the slide rail 5-4. The moving seat 5-5 pushes the support rod 5-6, causing the bracket 2 to tilt downwards at 45°. The special steel bar is placed on the bracket 2. The second motor 6-2 of the conveying component 6 is started, and the transmission gear 6-3 drives the rolling wheel 6-1 to rotate, bringing the bar into the bracket 2. At the same time, the height of the bracket 2 is gradually restored. The drive motor 4-2 of the cleaning component 4 is started, and the drive wheel 4-6 drives the transmission wheel 4-7 to rotate the rotating frame 4-3. The cleaning brush 4-4 cleans the surface of the bar, and at the same time, the vacuum cleaner 3 removes dust through the suction port 4-5. Finally, the bar enters the centerless lathe for processing.
[0055] It should be noted that the above embodiments are only used to illustrate the technical solutions of this disclosure and are not intended to limit it. Although this disclosure has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this disclosure without departing from the spirit and scope of the technical solutions of this disclosure, and all such modifications and substitutions should be covered within the scope of the claims of this disclosure.
