Description

Technical Field

[0001] The present invention belongs to the technical field of grinding instruments, and relates to a surface grinding device for processing nylon rods. Background Art

[0002] A nylon rod is an important engineering plastic, which can replace the wear-resistant parts of mechanical equipment and replace copper and alloys as the wear-resistant parts of equipment. It has good toughness, strong wear resistance, oil resistance, earthquake resistance, tensile and bending strength, and has the characteristics of small water absorption and good dimensional stability. Therefore, it is used to process various high-strength wear-resistant parts. During the processing of nylon rods, due to the relatively rough outer surface, it is necessary to grind the outer surface.

[0003] After retrieval, a patent with the authorized publication number of CN109590870B discloses a grinding device for nylon rod blanks, including a frame, a funnel arranged on the frame for placing rod blanks, a conveying device arranged on one side of the funnel corresponding to the frame for conveying rod blanks, a grinding device arranged on the other side of the conveying device relative to the funnel for grinding rod blanks, and a discharge port arranged on the other side of the grinding device relative to the conveying device for discharging.

[0004] During the grinding process of the above-mentioned patent for nylon rods, the nylon rods are fed into the grinding device one by one, and then ground from front to back along the axial direction of the nylon rod. During the grinding process, due to the length limitation of the grinding wheel, a single nylon rod needs to be divided into multiple sections and ground sequentially, and multiple nylon rods can only be ground one by one, resulting in relatively low overall efficiency. Moreover, when grinding some longer nylon rods, its conveying time is relatively long, resulting in too long processing time for a batch of goods, which will also lead to the problem of low production efficiency. Summary of the Invention

Detailed implementation manners

[0039] To make the objectives, technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings. It is hereby declared that the upper, lower, left, right, front, rear, inner, outer and other orientation terms that appear or will appear in the present invention are only based on the accompanying drawings of the present invention, and they do not specifically limit the present invention.

[0040] A surface grinding device for processing nylon rods, as Figures 1 - 7As shown, it includes a machine frame 1, a driving motor 2, a fixed disc 3, a spline shaft 4, a sliding disc 5, a grinding mechanism and a clamping mechanism. In the middle of the upper part of the front side of the machine frame 1, a driving motor 2 is installed. At the middle position of the upper part of the machine frame 1, a spline shaft 4 is rotatably connected. Between the spline shaft 4 and the output shaft of the driving motor 2, they are connected by a coupling. At the front side of the spline shaft 4, a fixed disc 3 is connected. At the rear side of the spline shaft 4, a sliding disc 5 is slidably connected. On the sliding disc 5, three bolts are connected by threads. The bolts can rotate on the sliding disc 5 to move and abut against the spline shaft 4 for fixing the sliding disc 5. On the machine frame 1, there is a grinding mechanism for grinding nylon rods. Between the sliding disc 5 and the fixed disc 3, there is a clamping mechanism for clamping nylon rods.

[0041] As Figure 4 and Figure 5 shown, the grinding mechanism includes a fixed mounting plate 61, an arc-shaped grinding plate 62, a servo motor 63, a connecting frame 621, a connecting frame 64, a triangular pressing block 65 and an adjusting component. At the upper part of the right side of the machine frame 1, a fixed mounting plate 61 is connected. On the fixed mounting plate 61, a connecting frame 621 is slidably connected. On the left side of the connecting frame 621, an arc-shaped grinding plate 62 is slidably connected. The arc-shaped grinding plate 62 can slide back and forth along the connecting frame 621. At the middle position of the right side of the arc-shaped grinding plate 62, a connecting frame 64 is connected. At the middle position of the right side of the fixed mounting plate 61, a servo motor 63 is installed. On the output shaft of the servo motor 63, a triangular pressing block 65 is connected by a coupling. The triangular pressing block 65 is located inside the connecting frame 64, so that when the triangular pressing block 65 rotates, it can repeatedly press the connecting frame 64 to move. Between the fixed mounting plate 61 and the connecting frame 621, there is an adjusting component for adjusting the positions of the connecting frame 621 and the arc-shaped grinding plate 62.

[0042] As Figure 4 and Figure 5 shown, the adjusting component includes a transmission screw 622 and an adjusting nut 623. On the front and rear sides of the right side of the connecting frame 621, transmission screws 622 are connected. On the front and rear sides of the fixed mounting plate 61, adjusting nuts 623 are rotatably connected. The adjusting nut 623 is in threaded cooperation with the transmission screw 622, so that when the adjusting nut 623 rotates, it can drive the transmission screw 622 to move left and right through the thread. On the outer right side of the adjusting nut 623, a connecting plate is provided to facilitate the operation of rotating the adjusting nut 623.

[0043] As Figure 6 and Figure 7As shown, the clamping mechanism includes a connecting block 71, a clamping rod 72, a first elastic member 73, a transmission gear 74, and an arc-shaped rack 75. A plurality of connecting blocks 71 are evenly spaced along the circumference and connected to both the sliding disc 5 and the fixed disc 3. A rotating ring is rotatably connected to the connecting block 71, and a clamping rod 72 is slidably connected within the rotating ring. Spikes are evenly spaced on the side of the two clamping rods 72 close to each other to facilitate clamping the nylon rod. On the side of the two clamping rods 72 far from each other, a convex edge is provided. At the far ends of the two clamping rods 72 far from each other, a transmission gear 74 is connected. A first elastic member 73 is connected between the clamping rod 72 and the rotating ring. The first elastic member 73 is a tension spring. An arc-shaped rack 75 is provided on the right side of the fixed disc 3. The arc-shaped rack 75 is located at the moving trajectory of the transmission gear 74, and the transmission gear 74 can move to engage with the arc-shaped rack 75.

[0044] When it is necessary to polish the surface of the nylon rod, this polishing device can be used. During operation, first pull the two corresponding clamping rods 72 away from each other, and the first elastic member 73 is stretched. Then place the nylon rod between the two separated clamping rods 72. Subsequently, release the clamping rods 72. Under the action of the first elastic member 73, the clamping rods 72 reset to clamp the nylon rod. Then control the driving motor 2 to drive the spline shaft 4 to rotate. When the spline shaft 4 rotates, it drives the fixed disc 3 and the sliding disc 5 to rotate, thereby driving the clamping rods 72 to rotate and making the nylon rod move. When the nylon rod moves, it can contact the arc-shaped polishing plate 62. After the nylon rod moves to contact the arc-shaped polishing plate 62, the transmission gear 74 also moves to engage with the arc-shaped rack 75. At this time, when the transmission gear 74 continues to rotate, it can be rubbed by the arc-shaped rack 75 and rotate, thereby driving the clamping rods 72 to rotate. When the clamping rods 72 rotate, they can drive the nylon rod to rotate. At the same time, control the servo motor 63 to drive the triangular extrusion block 65 to rotate. When the triangular extrusion block 65 rotates, it can repeatedly squeeze the front and rear sides of the connecting frame 64, causing the connecting frame 64 to move back and forth, thereby driving the arc-shaped polishing plate 62 to move back and forth. In this way, the polishing of the nylon rod can be achieved. And during the polishing process, the nylon rod can be continuously conveyed for polishing, and multiple nylon rods can be polished simultaneously at one time, with higher overall polishing efficiency. During actual operation, if the lengths of the nylon rods are different, the distance between the two clamping rods 72 can be adjusted by sliding the sliding disc 5 back and forth, so as to clamp nylon rods of different lengths. If the diameters of the nylon rods are different, the position of the arc-shaped polishing plate 62 can be adjusted by rotating the adjusting sleeve 623 to drive the transmission screw 622 to move left and right, thereby driving the connecting frame 621 and the arc-shaped polishing plate 62 to move left and right, so as to adapt to the polishing of nylon rods of different diameters.

[0045] Such as Figures 8 - 11As shown in the figure, it further includes a blanking mechanism. The blanking mechanism includes a blanking hopper 81, an adjustable limiting plate 82, an arc-shaped material receiving plate 83, and a second elastic member 831. The top of the frame 1 is connected with a blanking hopper 81. The bottom of the blanking hopper 81 is provided with a blanking channel capable of accommodating the discharge of one nylon rod. The adjustable limiting plate 82 is slidably connected to the rear side inside the blanking hopper 81. The lower right side of the adjustable limiting plate 82 passes through the blanking hopper 81 and can slide back and forth in the blanking hopper 81. The front side of the lower part of the blanking hopper 81 and the position where the lower part of the adjustable limiting plate 82 passes through the blanking hopper 81 are both slidably connected with an arc-shaped material receiving plate 83. The top of the right side of the arc-shaped material receiving plate 83 is lower than the top of the arc-shaped position on the left side of the arc-shaped material receiving plate 83. The two arc-shaped material receiving plates 83 are respectively connected with a second elastic member 831 between the blanking hopper 81 and the adjustable limiting plate 82. The second elastic member 831 is a compression spring.

[0046] As Figures 8 - 13 As shown in the figure, it further includes a limiting mechanism. The limiting mechanism includes a pressing plate 84, a sliding limiting plate 85, a limiting convex ring 86, and a third elastic member 87. The front side of the bottom of the blanking hopper 81 and the bottom of the adjustable limiting plate 82 are both connected with a pressing plate 84. The left side of the bottom of the pressing plate 84 is inclined. The sliding limiting plate 85 is slidably connected inside the connecting block 71. The middle of the clamping rod 72 is connected with a limiting convex ring 86. The limiting convex ring 86 is slidably connected with the connecting block 71. The side of the upper part of the sliding limiting plate 85 facing the limiting convex ring 86 and the side of the limiting convex ring 86 facing the sliding limiting plate 85 are both inclined. The pressing plate 84 is located at the moving track of the sliding limiting plate 85, so that the inclined surface on the pressing plate 84 can press the sliding limiting plate 85 to move downward. A third elastic member 87 is connected between the sliding limiting plate 85 and the connecting block 71. The third elastic member 87 is a return spring. When the limiting convex ring 86 moves outward along with the clamping rod 72, the first elastic member 73 is compressed. The bottom inclined surface of the limiting convex ring 86 contacts and fits with the top inclined surface of the sliding limiting plate 85, and presses and pushes the sliding limiting plate 85 to move downward. The third elastic member 87 is compressed. After the limiting convex ring 86 moves to the outside of the sliding limiting plate 85, the sliding limiting plate 85 rises under the action of the third elastic member 87, preventing the limiting convex ring 86 from moving inward to reset, so that the clamping rod 72 remains in the open state until the sliding limiting plate 85 contacts the bottom inclined surface of the pressing plate 84. The sliding limiting plate 85 is pressed to move downward, releasing the limit on the limiting convex ring 86. Only then can the clamping rod 72 move inward under the reset action of the first elastic member 73 to clamp the nylon rod.

[0047] During use, the clamping rod 72 that has not been rotated below the hopper 81 can be pulled outwards first. The first elastic member 73 is stretched. When the clamping rod 72 is pulled to move, it can drive the limit convex ring 86 to move. When the limit convex ring 86 moves, it can squeeze the sliding limit plate 85 to move downwards through the inclined part on it and the inclined part of the sliding limit plate 85, and the third elastic member 87 is compressed until the limit convex ring 86 moves to no longer contact the sliding limit plate 85. At this time, under the action of the third elastic member 87, the sliding limit plate 85 resets to block the limit convex ring 86, thereby limiting the clamping rod 72. When adding nylon rods, the nylon rods can be added into the hopper 81. The nylon rods in the hopper 81 will fall on the arc-shaped material receiving plate 83 when they fall, so that the arc-shaped material receiving plate 83 can catch the nylon rods. When the sliding disc 5 and the fixed disc 3 rotate, they can drive the sliding limit plate 85 to rotate. When the sliding limit plate 85 rotates, it can contact the pressing plate 84. At this time, if the sliding limit plate 85 continues to slide, it will be squeezed and move downwards by the inclined position on the pressing plate 84, and the third elastic member 87 is compressed. When the sliding limit plate 85 moves downwards, it will disengage from the limit convex ring 86. At this time, the clamping rod 72 also aligns with the nylon rod located at the arc-shaped material receiving plate 83. Under the action of the first elastic member 73, the clamping rod 72 resets and can clamp the nylon rod. Subsequently, when the clamping rod 72 continues to rotate, it can take out the nylon rod. When taking out the nylon rod, the nylon rod can squeeze the arc-shaped material receiving plate 83 to move downwards, so that the second elastic member 831 is compressed. After being taken out, the nylon rod disengages from the arc-shaped material receiving plate 83. Under the action of the second elastic member 831, the arc-shaped material receiving plate 83 resets. At this time, the materials in the hopper 81 fall on the arc-shaped material receiving plate 83 again. Repeating this way can achieve the effect of automatically adding nylon rods, which is more convenient during operation. When the length of the nylon rod changes, the adjustable limit plate 82 can be pulled to slide back and forth for adjustment. When the adjustable limit plate 82 is adjusted, the positions of the arc-shaped material receiving plate 83 and the pressing plate 84 on it can be adjusted synchronously.

[0048] As Figures 14 - 16 shown, it further includes an unlocking mechanism. The unlocking mechanism includes a guide frame 91, a fixed unlocking block 92, an adjustment screw 93 and a movable unlocking block 94. The middle part of the lower part inside the frame 1 is connected with a guide frame 91. The front side of the guide frame 91 is connected with a fixed unlocking block 92. The rear side of the guide frame 91 is slidably connected with a movable unlocking block 94. The rear side of the guide frame 91 is rotatably connected with an adjustment screw 93. The rear end of the adjustment screw 93 passes through the frame 1 and is connected with a hand crank for facilitating the rotation of the adjustment screw 93. The adjustment screw 93 is in threaded cooperation with the movable unlocking block 94. The mutually remote sides of the fixed unlocking block 92 and the movable unlocking block 94 are both provided with inclined surfaces for squeezing the clamping rod 72 to unlock the nylon rod.

[0049] After the clamping rod 72 clamps the nylon rod and finishes grinding, the clamping rod 72 continues to rotate, and its upper convex edges will respectively contact the inclined surfaces of the fixed unlocking block 92 and the movable unlocking block 94. At this time, when the clamping rod 72 continues to move, the inclined surfaces of the fixed unlocking block 92 and the movable unlocking block 94 can respectively squeeze the convex edges on both sides away from each other, thereby driving the clamping rods 72 on both sides away from each other, so that the clamping rod 72 is separated from the nylon rod. At this time, the ground nylon rod will fall. In this way, the effect of automatically unloading the ground nylon rod can be achieved. When the clamping rods 72 on both sides move away from each other, they can also drive the limiting convex ring 86 to move until the limiting convex ring 86 moves to be stuck by the sliding limiting plate 85. In actual operation, if the position of the nylon rod needs to be adjusted, the position of the movable unlocking block 94 can be adjusted by rotating the position-adjusting screw 93.

[0050] As Figure 17 shown, it further includes a cleaning mechanism. The cleaning mechanism includes a material collecting hopper 101 and an electric cleaning brush 102. The right side of the bottom of the frame 1 is connected with the material collecting hopper 101. The upper part on the left side of the material collecting hopper 101 is provided with the electric cleaning brush 102. The clamping rod 72 can convey the nylon rod above the material collecting hopper 101 and contact the electric cleaning brush 102. At the same time, the electric cleaning brush 102 can be started to operate and rotate to clean the dust on the surface of the nylon rod.

[0051] As Figure 18 and Figure 19 shown, it further includes an arc-shaped material guiding plate 11. The arc-shaped material guiding plate 11 is arranged at the inner bottom of the frame 1. The right side of the arc-shaped material guiding plate 11 is provided with an upward arc surface for guiding the falling nylon rod to assist in sending out the nylon rod. When the clamping rod 72 unloads the nylon rod, the nylon rod can slide out along the arc-shaped material guiding plate 11.
