Description

Technical Field

[0001] This utility model relates to the field of hoisting technology for upper feed and discharge guard plates, and in particular to a quick fixing device for hoisting upper feed and discharge guard plates. Background Technology

[0002] Upper feed and discharge guard plates are key auxiliary components of machining equipment (such as abrasive wheel cutting machines and grinding machines). Their main functions are to guide workpieces precisely into and out of the machining area, prevent machining debris from flying, and ensure operator safety. These devices are mostly used in metal workpiece processing scenarios (such as profile cutting and parts grinding). The guard plate position needs frequent adjustment according to workpiece specifications (thickness, width), and environmental issues such as coolant corrosion and metal debris contamination during processing must also be addressed. Existing guard plate fixing devices mostly use bolts to directly fix them to the feeding table. When adjusting the position, the bolts need to be completely removed. In the machining scene, coolant (such as emulsion) is often used to cool the workpiece and grinding wheel. The coolant can easily penetrate into the bolts, nuts and other fixing components. Traditional exposed bolts are prone to corrosion due to long-term contact with coolant and metal shavings. Existing guard plates are mostly rigidly fixed and lack flexible adjustment structure. After long-term use, the guard plate is prone to slight deformation due to vibration and collision, resulting in unevenness on the guard plate surface. If the guard plate is tilted, the workpiece is prone to jamming during feeding. Therefore, we propose a top-feeding and discharge guard plate hoisting and fixing device. Utility Model Content

[0003] In view of this, this application provides a quick-fixing device for hoisting and fixing the upper feed and discharge guard plate, which aims to solve the above-mentioned technical problems.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: A quick-fixing device for hoisting and fixing an upper inlet / outlet guard plate includes a feeding platform. A feeding tray is fixedly installed on the top of the feeding platform. A T-shaped annular groove is formed on the top of the feeding tray. A T-shaped slider is slidably installed on the inner side of the T-shaped annular groove. Two fixing bolts are threaded on the top of the T-shaped slider. A cap nut is fixedly installed on the top of the fixing bolts. A hanging plate bracket is fixedly installed on the top of the T-shaped slider. A guide key is fixedly installed on the inner side of the hanging plate bracket. A positioning screw is threaded on the inner side of the guide key.

[0005] Preferably, round nuts are fixedly installed at the top and bottom of the hanging plate bracket, the positioning screw is bolted to the round nuts, and an mounting plate is fixedly installed on the outside of the positioning screw.

[0006] Preferably, two hexagon socket screws are threaded on the inner side of the mounting plate, and an upper feed plate or a lower discharge plate is fixedly installed at the bottom of the hexagon socket screws. The upper feed plate is located below the left hanging plate bracket, and the lower discharge plate is located below the right hanging plate bracket.

[0007] Preferably, the bottom of the mounting plate is fixedly installed with one end of two compression springs, and the other end of the compression springs is fixedly installed on the top of the upper feed plate and the lower discharge plate. The top of the upper feed plate and the lower discharge plate are both provided with hinges.

[0008] Preferably, the mounting plate has multiple square-head set screws threaded on its inner side, and the square-head set screws abut against the guide key and the positioning screw respectively.

[0009] Preferably, a drive motor is provided on the top of the feeding table, a drive shaft is fixedly installed on the output end of the drive motor, a grinding wheel is fixedly installed on the outer side of the drive shaft, and a keyway is provided on the top of the grinding wheel, the keyway being in contact with the drive shaft.

[0010] Preferably, the front side of the feeding platform is provided with a discharge trough, and multiple guide balls are rotatably installed on the bottom inner wall of the discharge trough.

[0011] Preferably, a ball bearing is rotatably mounted on the bottom of the T-shaped slider, and an anti-slip rubber pad is rotatably mounted on the bottom of the fixing bolt.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: This utility model discloses a quick-fixing device for hoisting and installing upper feed and discharge guard plates. The hanging plate bracket slides with the T-shaped groove of the feeding plate via a T-shaped slider. Loosening the fixing bolts allows the hanging plate bracket to move along the T-shaped groove, adjusting the front and rear positions of the upper feed plate and lower discharge plate to ensure that the arc of the plate close to the grinding wheel precisely matches the grinding wheel. The positioning screw slides inside the guide key and can be fixed in position with the round nut, thereby adjusting the vertical height of the mounting plate and guard plate. Position adjustment can be completed without disassembling the overall structure, adapting to the processing needs of workpieces of different thicknesses. This utility model discloses a quick-fixing device for hoisting and installing upper feed and discharge guard plates. The cap nut on the top of the fixing bolt can cover the bolt head to prevent dust and coolant from entering the bolt thread gap and avoid bolt corrosion, thus solving the problems of traditional exposed bolts being prone to rust and difficult to disassemble and assemble. The anti-slip rubber pad at the bottom of the fixing bolt can increase the friction between the fixing bolt and the T-shaped ring groove, preventing the bolt from loosening during device operation. The ball bearings at the bottom of the T-shaped slider reduce the sliding friction between it and the T-shaped ring groove, reduce wear, and extend the service life of the sliding parts.

[0016] To further understand the invention content, features and effects of this utility model, the following embodiments are provided, and detailed descriptions are given below in conjunction with the accompanying drawings; The structure of this utility model will now be described in detail with reference to the accompanying drawings.

[0017] refer to Figure 1-4 A quick-fixing device for lifting and fixing a top-feeding and unloading guard plate includes a feeding platform 1, a feeding tray 2 fixedly installed on the top of the feeding platform 1, a T-shaped annular groove 3 on the top of the feeding tray 2, a T-shaped slider 4 slidably installed on the inner side of the T-shaped annular groove 3, two fixing bolts 5 threadedly installed on the top of the T-shaped slider 4, a cap nut 6 fixedly installed on the top of the fixing bolts 5, a hanging plate bracket 7 fixedly installed on the top of the T-shaped slider 4, a guide key 8 fixedly installed on the inner side of the hanging plate bracket 7, and a positioning screw 9 threadedly installed on the inner side of the guide key 8; the positioning screw 9 slides inside the guide key 8, and can be fixed in position with the round nut 10, thereby adjusting the vertical height of the mounting plate 11 and the guard plate; the position adjustment can be completed without disassembling the overall structure, adapting to the processing requirements of workpieces of different thicknesses.

[0018] In this embodiment, round nuts 10 are fixedly installed at the top and bottom of the hanging plate bracket 7. The positioning screw 9 is bolted to the round nuts 10. The mounting plate 11 is fixedly installed on the outside of the positioning screw 9. The upper feed plate 13 and the lower discharge plate 14 are connected to the mounting plate 11 by hexagon socket screws 12. The guard plate can be replaced separately by removing the screws, without disassembling the core components such as the hanging plate bracket 7.

[0019] In this embodiment, two hexagon socket screws 12 are threaded on the inner side of the mounting plate 11. The bottom of the hexagon socket screws 12 is fixedly mounted with an upper feed plate 13 or a lower discharge plate 14. The upper feed plate 13 is located below the left hanging plate bracket 7, and the lower discharge plate 14 is located below the right hanging plate bracket 7. The hanging plate bracket 7 slides with the T-shaped annular groove 3 of the feeding plate 2 through the T-shaped slider 4. Loosening the fixing bolt 5 can push the hanging plate bracket 7 to move along the T-shaped annular groove 3, adjusting the front and rear positions of the upper feed plate 13 and the lower discharge plate 14 to ensure that the arc of the upper feed plate 13 and the lower discharge plate 14 are precisely matched with the grinding wheel 18.

[0020] In this embodiment, one end of two compression springs 16 is fixedly installed on the bottom of the mounting plate 11, and the other end of the compression springs 16 is fixedly installed on the top of the upper feed plate 13 and the lower discharge plate 14. Hinges 15 are provided on the top of both the upper feed plate 13 and the lower discharge plate 14. The compression springs 16 at the bottom of the mounting plate 11 provide elastic support for the upper feed plate 13 and the lower discharge plate 14. The height of the guard plate can be finely adjusted with the hexagonal screws 12. Tightening the hexagonal screws can press down the guard plate, and loosening them will cause the compression springs to rebound and lift the guard plate, easily adjusting the flatness of the guard plate and avoiding workpiece feeding jamming or processing deviation caused by the tilt of the guard plate.

[0021] In this embodiment, a plurality of square-headed set screws 17 are threaded on the inner side of the mounting plate 11, and the square-headed set screws 17 abut against the guide key 8 and the positioning screw 9 respectively.

[0022] In this embodiment, a drive motor is provided on the top of the feeding table 1, and a drive shaft 20 is fixedly installed at the output end of the drive motor. A grinding wheel 18 is fixedly installed on the outer side of the drive shaft 20. A keyway 19 is provided on the top of the grinding wheel 18, and the keyway 19 fits into the drive shaft 20.

[0023] In this embodiment, a discharge trough 21 is provided on the front side of the feeding platform 1, and a plurality of guide balls 22 are rotatably installed on the bottom inner wall of the discharge trough 21. The guide balls 22 at the bottom of the discharge trough 21 on the front side of the feeding platform 1 can reduce friction when the workpiece is discharged, reduce the risk of workpiece scratches, and at the same time, the guide balls are easy to clean and maintain. The drive shaft 20 and the grinding wheel 18 are connected by a keyway 19, so no additional alignment is required when disassembling and assembling the grinding wheel, which improves maintenance efficiency.

[0024] In this embodiment, a ball bearing is rotatably mounted on the bottom of the T-shaped slider 4, and an anti-slip rubber pad is rotatably mounted on the bottom of the fixing bolt 5. The ball bearing helps the T-shaped slider 4 to be relatively stable during sliding, and will not cause a situation where the friction is too great and it is difficult to slide. The anti-slip contact allows the fixing bolt 5 to abut against the bottom inner wall of the T-shaped annular groove 3 after it is lowered, which can lock the position of the T-shaped slider 4.

[0025] Specifically, the hanging plate bracket 7 slides with the T-shaped annular groove 3 of the feeding plate 2 via the T-shaped slider 4. Loosening the fixing bolt 5 allows the hanging plate bracket 7 to move along the T-shaped annular groove 3, adjusting the front and rear positions of the upper feed plate 13 and the lower discharge plate 14 to ensure that the arc of the upper feed plate 13 and the lower discharge plate 14 are precisely matched with the grinding wheel 18. The positioning screw 9 slides inside the guide key 8 and can be fixed in position with the round nut 10, thereby adjusting the height of the mounting plate 11 and the guard plate. The position adjustment can be completed without disassembling the overall structure, adapting to the processing requirements of workpieces of different thicknesses. The cap nut 6 on the top of the fixing bolt 5 can cover the bolt head to prevent dust and coolant from entering the bolt thread gap, avoid bolt corrosion, and solve the problems of traditional exposed bolts being prone to rust and difficult to disassemble and assemble; the anti-slip rubber pad at the bottom of the fixing bolt 5 can increase the friction between the fixing bolt 5 and the T-shaped ring groove 3 to prevent the bolt from loosening during device operation; the ball bearings at the bottom of the T-shaped slider 4 reduce its sliding friction with the T-shaped ring groove 3, reduce wear, and extend the service life of the sliding parts; The compression spring 16 at the bottom of the mounting plate 11 provides elastic support for the upper feed plate 13 and the lower discharge plate 14. With the help of the hex socket screw 12, the height of the guard plate can be finely adjusted. Tightening the hex socket screw can press down the guard plate, and loosening it will cause the compression spring to rebound and lift the guard plate, easily adjusting the flatness of the guard plate and avoiding workpiece feeding jamming or processing deviation caused by the tilt of the guard plate. The square head set screw 17 can lock the position of the guide key 8 and the positioning screw 9 to prevent the parts from shifting after adjustment and ensure the stability of the guard plate position during processing. The upper feed plate 13 and the lower discharge plate 14 are connected to the mounting plate 11 by hexagon socket screws 12. The guard plate can be replaced by removing the screws without disassembling core components such as the hanging plate bracket 7. The bottom of the discharge chute 21 on the front side of the feeding table 1 is equipped with guide balls 22, which can reduce friction during workpiece discharge, reduce the risk of workpiece scratches, and facilitate cleaning and maintenance. The drive shaft 20 and the grinding wheel 18 are connected by a keyway 19, which eliminates the need for additional alignment when disassembling and assembling the grinding wheel, thus improving maintenance efficiency. The hinge 15 at the top of the upper feed plate 13 can be connected to a high baffle to prevent workpieces from stacking too high and causing feeding blockage, thus reducing the risk of equipment jamming. The bolted connection between the positioning screw 9 and the round nut 10, and the locking action of the square head set screw 17, form multiple fixation to prevent the guard plate from loosening and falling off during high-speed processing such as grinding wheel rotation. The overall structure restricts the movement direction of the components and improves the stability of the device operation through the cooperation of the T-shaped slider and the ring groove, and the guide key and the screw.

[0026] It should be noted that although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
