Description

Technical Field

[0001] The utility model relates to the technical field of burr removal, and particularly relates to a quick cleaning fixture for pressing burrs. Background Technique

[0002] Powder metallurgy is a process method for manufacturing parts and materials with complex shapes by processing metal or non-metal material powders through processes such as pressing and sintering. First, the required metal or non-metal materials are processed into tiny powder particles. The mixed powders are put into a mold and formed into the required shape and size through pressing or injection molding. Additional additives or lubricants can be used during the forming process to improve the forming performance. Finally, through high-temperature calcination, the powder particles inside the part are sintered to achieve the required mechanical properties. The powder metallurgy process has a high material utilization rate, can reduce material waste, avoid unnecessary cutting or processing processes, and is widely used in fields such as the automotive industry, electronics industry, and aerospace industry. It is one of the important methods for manufacturing high-performance and complex-structured parts.

[0003] After a powder metallurgy machine finishes stamping a part, the part is ejected and transferred by a mechanical gripper. Due to the errors and wear of the pressing mold, the rough blank of the powder metallurgy after preliminary pressing is prone to generating burrs or accumulating powder on the upper and lower forming surfaces. Before entering high-temperature calcination, the burrs and powder on the upper and lower surfaces of the part need to be removed, and in general production processes, most of them are removed manually.

[0004] The Chinese patent of a burr cleaning mechanism for powder pressing products and a powder pressing and forming system with the publication number of CN219703501U proposes that a reciprocating burr cleaning mechanism can be used to remove burrs from parts, but this technology can only remove burrs from the upper surface of the part. During the powder metallurgy pressing process, burrs are also likely to be generated on the lower surface of the part. This existing technology cannot remove burrs from the lower surface of the part, and burrs cannot be completely removed during use. Additional processes are still required to remove burrs from the lower surface of the part. Therefore, we propose a quick cleaning fixture for pressing burrs to solve the problem that the prior art fails to remove burrs from the upper and lower surfaces of powder-formed parts at one time.

[0028] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0029] As Figures 1 to 8A rapid cleaning fixture for pressing burrs, as shown, includes: a mounting base plate 1, on the top of which a slide rail 2 is fixedly installed. A slider 3 is slidably installed on the slide rail 2. On the top of the slider 3, a rotating shaft seat 4 is fixedly installed. On the top of the mounting base plate 1, a cylinder 6 is fixedly installed. The telescopic end of the cylinder 6 is fixedly connected to one side of the rotating shaft seat 4. A central shaft 11 is rotatably installed in the rotating shaft seat 4; a clamping component, which is fixedly installed on one side of the central shaft 11 and is used to extend downward to clamp the workpiece; a flipping component, which is rotatably installed on both sides of the rotating shaft seat 4 and is used to flip the clamping component during movement; a cleaning component, which is slidably installed on the top of the rotating shaft seat 4 and is used to remove burrs from the workpiece on the clamping component; during use, when the workpiece formed by powder die-casting is pushed out of the lower die, the telescopic end of the cylinder 6 retracts, controlling the slider 3 to slide to one side. During the sliding to one side, the clamping component extends downward to clamp the workpiece. After the clamping is completed, the telescopic end of the cylinder 6 extends, pushing the slider 3 to slide to the other side. At this time, during the sliding process, under the action of the flipping component, the clamping component will have three movements, namely the front movement, the flipping movement, and the reverse movement. During the front movement and the reverse movement, the cleaning mechanism will remove burrs from the front and back surfaces of the workpiece. After reaching the other end, the clamping component releases the workpiece. Compared with the prior art, through the cooperation of the clamping component and the flipping component, the flipping of the workpiece is realized. Through the cooperation of the flipping component and the cleaning component, the cleaning of burrs on the upper and lower surfaces of the workpiece is realized. At the same time, through the linkage between the components, the device can complete the lowering, lifting, flipping of the clamping jaw 5 and the removal of burrs from the workpiece only through the cylinder 6. While improving the cleaning effect of burrs, the device cost is saved, and the practicability is very high.

[0030] As Figure 1 , Figure 5As shown, the clamping component includes a clamping base 19 fixed to one side of the central shaft 11. Double linkages 20 are hingedly installed on both sides of the clamping base 19. The double linkages 20 are two parallel linkages with the same length. A blocking block for restricting the upward lifting of the double linkages 20 is provided on the clamping base 19. The other ends of the double linkages 20 are hingedly installed with clamping jaws 5. A spring 21 is fixedly installed at the top of one end of the clamping base 19. The other end of the spring 21 is fixedly connected to one side of the clamping jaw 5. The spring 21 is inclined. The connection point of the spring 21 and the clamping base 19 is at a high point and higher than the connection point of the double linkages 20 and the clamping base 19. The connection point of the spring 21 and the clamping jaw 5 is at a low point. A downward pressing baffle 22 is fixedly installed at the top of the mounting base plate 1. The downward pressing baffle 22 is adapted to the clamping jaw 5. The downward pressing baffle 22 is L-shaped. A section of slope is provided on the side of the downward pressing baffle 22 facing the clamping jaw 5. The highest point of the slope is higher than the top surface of the clamping jaw 5. When the air cylinder 6 contracts, it can drive the slider 3 to move on the slide rail 2. During the movement of the slider 3, the clamping jaw 5 gradually comes into contact with the downward pressing baffle 22 and moves downward under the action of the slope on the downward pressing baffle 22. Due to the arranged double linkages 20, the clamping jaw 5 can maintain a horizontal downward movement, thereby clamping the workpiece. This is an existing structure and will not be elaborated here. Since the spring 21 is connected to the clamping jaw 5, when the air cylinder 6 extends, the clamping jaw 5 gradually separates from the downward pressing baffle 22. Due to the pulling of the spring 21, the clamping jaw 5 closely moves upward along the slope of the downward pressing baffle 22 and returns to the horizontal position after separating from the downward pressing baffle 22. Through the linkage with the air cylinder 6, the clamping jaw 5 can achieve a downward translation without a separate power source, thereby completing the clamping process of the workpiece, reducing the manufacturing cost, and making the device more practical.

[0031] As Figure 2 , Figure 3 , Figure 6 and Figure 8As shown, the flipping component includes a movable clamping block 10 fixedly installed on the other side of the central shaft 11. There are two sets of cylindrical pins arranged on one side of the movable clamping block 10, and one set of cylindrical pins is coaxially arranged with the central shaft 11. One side of the mounting base plate 1 is fixedly installed with a chute plate 7. The chute plate 7 is provided with a first chute 8 and a second chute 9. The first chute 8 is a horizontal track, and the second chute 9 is provided with an arc-shaped track that is horizontally arranged and deflected to one side. The second chute 9 is of a symmetric structure and its center line is located at the arc-shaped track. One set of cylindrical pins of the movable clamping block 10 that is coaxially arranged with the central shaft 11 is slidably connected to the first chute 8, and the other set of cylindrical pins of the movable clamping block 10 is movably connected to the second chute 9. While the air cylinder 6 pushes the slider 3 to move, the movable clamping block 10 moves in the first chute 8 and the second chute 9. During the process of moving to one side, the pin column under the movable clamping block 10 gradually moves downward under the action of the second chute 9 and reaches the bottom end through an arc-shaped route. Then, during the continuous movement of the movable clamping block 10, the pin column below is lifted upward through another arc-shaped route on the second chute 9, causing the movable clamping block 10 to gradually flip. The central shaft 11 fixedly connected to the movable clamping block 10 will also rotate along with the flipping of the movable clamping block 10, thereby driving the clamping component to flip. At this time, the lower surface of the workpiece faces upward and has a certain angle with the horizontal plane. Under the action of the cleaning component, the burrs on the lower surface of the workpiece can be cleaned up. Through the cooperation of the movable clamping block 10 with the first chute 8 and the second chute 9, the clamping component can change its posture during the movement, making the lower surface of the workpiece face upward, which is convenient for the cleaning component to deburr the workpiece. Compared with the prior art, the upper and lower surfaces of the workpiece can be deburred at one time, resulting in a better deburring effect. Moreover, the cost of manufacturing is reduced through the linkage structure, and the practicality of the device is improved.

[0032] As Figure 1 , Figure 3 , Figure 4 , Figure 6 and Figure 7As shown in the figure, the cleaning assembly includes a sliding column 12 fixed to the top of the rotating shaft seat 4. The top of the sliding column 12 is fixedly installed with a top plate 14. A sliding mounting seat 13 is slidably installed on the sliding column 12. The top of the sliding mounting seat 13 is fixedly installed with a cross arm beam 15. A pulley 16 is rotatably installed at the bottom of one side of the cross arm beam 15. A cleaning roller 17 is fixedly installed on the other side of the cross arm beam 15. The cleaning roller 17 is located directly above the clamping jaw 5. A motor is arranged inside the cleaning roller 17. The stator of the motor is fixedly connected to the outer shell of the cleaning roller 17, and the rotor of the motor is fixedly connected to the brush roller of the cleaning roller 17. A corrugated pipe 18 is arranged on one side of the outer shell of the cleaning roller 17. The corrugated pipe 18 is communicated with the cleaning roller 17 and is communicated with an external dust suction device. A cam 23 is fixedly installed on one side of the central shaft 11. The cam 23 is arranged in a matching manner with the pulley 16. When the clamping jaw 5 just disengages from the pressing baffle 22, the cleaning roller 17 contacts the upper surface of the workpiece. At this time, the burrs on the upper surface of the workpiece can be removed. During the continuous movement of the clamping jaw 5, the flipping assembly drives the clamping assembly to rotate. At this time, the cam 23 starts to rotate synchronously. While the workpiece is being flipped, the convex end of the cam 23 presses against the pulley 16 and moves upward. Under the action of the sliding column 12 and the sliding mounting seat 13, the cleaning roller 17 moves upward to avoid the clamping jaw 5 during flipping and prevent damage to the clamping jaw 5. After the workpiece is flipped, the convex end of the cam 23 is offset from the pulley 16, and the cleaning roller 17 moves downward and contacts the lower surface of the workpiece again to remove burrs. Through the corrugated pipe 18 arranged on the outer shell of the cleaning roller 17, the burrs and powder swept by the cleaning roller 17 can be collected to avoid falling, reducing the pollution of the powder and burrs to the air and preventing the flying powder and burrs from causing harm to the machine and the operator.

[0033] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
