Description

Technical Field

[0001] The invention relates to a polishing device for making stainless steel fasteners, belonging to the technical field of stainless steel fastener production. Background Art

[0002] Stainless steel fasteners is a professional term covering a wide range of products. They are often used in key components of high-end mechanical equipment due to their beauty, durability and excellent corrosion resistance. Among them, two-way threaded stainless steel rods are one of the important specifications of this type of fasteners. However, during the production process, the outer surface of these stainless steel fasteners is prone to defects such as burrs, which not only affects the appearance, but also may reduce its performance. Therefore, in order to ensure the quality of stainless steel fasteners, it is usually necessary to polish their surfaces;

[0003] At present, there are two main polishing technologies on the market. The first method is to use a grinding wheel to polish stainless steel fasteners. Although this method can achieve certain results, it often requires frequent flipping of the workpiece and replacement of materials during operation, which not only increases labor intensity, but also prolongs the time of the entire polishing process. Another common polishing method is to use the friction between granular abrasives and stainless steel fasteners to remove surface defects. Although this method simplifies the operation process to a certain extent, due to the hardness characteristics of the stainless steel material itself, some stubborn burrs are difficult to completely remove, resulting in slight unevenness in the finished product after polishing, which in turn affects the final product effect and processing efficiency.

DETAILED DESCRIPTION

[0029] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0032] The U-shaped plate 5 extending from the left side of the conveyor belt 4 is attached to the upper end of the conveyor belt 4, and the conveyed stainless steel fasteners are straightened through the U-shaped plate 5, and the transverse parts of the two fixing plates 52 with L-shaped cross sections respectively installed on the upper ends of the two mounting plates 42 are respectively arranged on the front and rear ends of the U-shaped plate 5, and the two fixing plates 52 are used in combination to lift the U-shaped plate 5, and then two guide plates 51 with a V-shaped structure arranged with a narrow left and a wide right, which are located on the left side of the feeding equipment and are integrated with the U-shaped plate 5 and attached to the upper end of the conveyor belt 4, are respectively arranged on the right ends of the two straight plate parts of the U-shaped plate 5, and the two guide plates 51 are used in combination to guide the stainless steel fasteners into the U-shaped plate 5;

[0033] A trapezoidal cylinder 53 located at the lower left of the conveyor belt 4 and arranged in a narrow lower part and wide upper part is connected and arranged on the lower end of the U-shaped plate 5, and the stainless steel fasteners outputted from the conveyor belt 4 are discharged through the trapezoidal cylinder 53, and the lower annular plate 64 located on the left side of the conveyor belt 4 is rotatably connected to the lower end of the straight cylinder 6, and a mounting carrier is provided for the lower annular plate 64 and other components through the straight cylinder 6, and then an upper annular plate 62 is arranged on the upper end of the straight cylinder 6, and a mounting carrier is provided for the conical cylinder 61 through the upper annular plate 62, and a conical cylinder 61 located directly below the trapezoidal cylinder 53 and arranged in a wide upper part and narrow lower part is connected and arranged on the upper end of the upper annular plate 62, and the stainless steel fasteners are introduced into the polishing structure formed by a plurality of polishing wheels 67 through the conical cylinder 61;

[0034] A plurality of polishing wheels 67 are equidistantly arranged on the upper end of the lower annular plate 64, and the plurality of polishing wheels 67 are used in combination to polish the outer surface of the stainless steel fastener, and a second annular gear 672 located on the upper side of the polishing wheel 67 is arranged on the inner wall of the straight cylinder 6, and a plurality of auxiliary gears 671 meshing with the inner wall of the second annular gear 672 are respectively arranged on the upper ends of the plurality of polishing wheels 67, and the second annular gear 672 and the auxiliary gear 671 are used in combination to make the polishing wheel 67 rotate;

[0035] Two support plates 66 with L-shaped cross-sections and vertical parts arranged on the upper end of the table 2 are respectively installed on the front and rear ends of the straight cylinder 6. The two support plates 66 are used in combination to lift the straight cylinder 6, and the first ring gear 65 is set on the ring end of the lower ring plate 64. The lower ring plate 64 is rotated through the first ring gear 65, and then the rotating gear 71 is engaged with the right end of the first ring gear 65. The first ring gear 65 is rotated through the rotating gear 71, and the fixed part of the first driving device connecting the output shaft and the rotating gear 71 is set on the upper end of the table 2. The rotating gear 71 is driven to rotate through the first driving device. The first driving device can use a first motor 7.

[0036] When in use, a large number of stainless steel fasteners are first put into the vibration plate 3, and then the vibration plate 3, the first motor 7 and the second motor 41 are started. The vibration plate 3 will work to convey the stainless steel fasteners one by one to the upper end of the conveyor belt 4, and at the same time, the second motor 41 will work to drive the corresponding roller 43 to rotate, and with the assistance of another roller 43, the conveyor belt 4 will move, and then the stainless steel fasteners on the conveyor belt 4 will move to the left. At this time, the two guide plates 51 will guide the stainless steel fasteners moving to the left into the U-shaped plate 5, and use the U-shaped plate 5 to correct the stainless steel fasteners to a horizontal state, so as to achieve correction processing of the stainless steel fasteners to be loaded, effectively reduce the probability of the stainless steel fasteners being tilted due to the mechanical loading method, so that the stainless steel fasteners can effectively enter the subsequent polishing process, and effectively ensure the polishing effect and efficiency;

[0037] Then the stainless steel fastener in the horizontal state will enter the trapezoidal cylinder 53 and transform the stainless steel fastener into a vertical state. Then the stainless steel fastener in the vertical state will enter the polishing structure formed by the multiple polishing wheels 67 along the conical cylinder 61 and the upper annular plate 62. At the same time, the first motor 7 will drive the rotating gear 71 to rotate. Since the rotating gear 71 and the first annular gear 65 are meshed with each other, the rotation of the rotating gear 71 will cause the first annular gear 65 to rotate, and then the lower annular plate 64 will rotate, thereby causing the multiple polishing wheels 67 to rotate.

[0038] The rotation of the polishing wheel 67 will cause the auxiliary gear 671 to rotate along the inner wall of the second ring gear 672. Because the second ring gear 672 and the auxiliary gear 671 are meshed with each other, the auxiliary gear 671 rotates along the inner wall of the second ring gear 672 and rotates on its own at the same time, thereby causing multiple polishing wheels 67 to rotate on their own. The multiple polishing wheels 67 that rotate in both directions are used to polish and grind the outer surface of the incoming stainless steel fasteners. At the same time, the stainless steel fasteners continue to move downward under their own weight and are discharged from the lower ring plate 64, thereby achieving mechanical and orderly polishing of the stainless steel fasteners, effectively reducing the probability of slight unevenness on the outer surface of the discharged stainless steel fasteners due to factors such as hard burrs, effectively reducing labor intensity and time, and effectively ensuring polishing effect and efficiency.

[0039] Embodiment 2: Figure 1 , Figure 2 , Figure 3 , Figure 7 and Figure 8 As shown, the annular pressure plate 631 is fitted on the lower end of the lower annular plate 64, and the rubber plate 63 is limitedly installed through the annular pressure plate 631, and the rods of the T-shaped rods 633, which are equidistantly arranged on the lower end of the lower annular plate 64 and are slidably connected to the annular pressure plate 631 and are located on the upper side of the table 2, are equidistantly arranged. The multiple T-shaped rods 633 are used in conjunction to limit the annular pressure plate 631. Then, the elastic member 632 located on the outer side of the rod of the T-shaped rod 633 is arranged between the upper end of the transverse part of the T-shaped rod 633 and the lower end of the annular pressure plate 631. The elastic member 632 is used to apply an upward pressure to the annular pressure plate 631, and the elastic member 632 can be a spring.

[0040] A groove is formed on the lower end surface of the lower annular plate 64 to provide installation space for the rubber plate 63. The rubber plate 63 located at the upper end of the annular pressure plate 631 is set in the groove. The stainless steel fasteners entering the straight cylinder 6 are restricted by the rubber plate 63. A cross groove is formed on the lower end surface of the rubber plate 63 to penetrate the rubber plate 63 and is located on the inner side of the lower annular plate 64 and the inner side of the annular pressure plate 631. The stainless steel fasteners penetrate the rubber plate 63 through the cross groove. A discharge groove 21 is formed on the upper end surface of the table plate 2 to extend to the left end of the table plate 2 and has a trapezoidal cross section with a wide left and narrow right arrangement and is located directly below the annular pressure plate 631. The stainless steel fasteners discharged after polishing are discharged through the discharge groove 21.

[0041] After the stainless steel fastener in the vertical state enters the polishing structure formed by the multiple polishing wheels 67, the lower end of the stainless steel fastener contacts the upper end of the rubber plate 63, and the rubber plate 63 will restrict the stainless steel fastener in the polishing structure, and the multiple polishing wheels 67 are rotated by the first motor 7, the rotating gear 71, the first ring gear 65, the lower ring plate 64, the auxiliary gear 671 and the second ring gear 672, so that the outer surface of the stainless steel fastener that enters is polished and polished by the multiple polishing wheels 67 that rotate in both directions;

[0042] When the subsequent stainless steel fasteners in the vertical state enter the polishing structure again, the two stainless steel fasteners will fit each other. At this time, the upper stainless steel fastener exerts downward pressure on the lower stainless steel fastener under the action of its own weight, and the stainless steel fasteners in the vertical state continue to be transported into the polishing structure. Then, the lowermost stainless steel fastener is deformed under the downward pressure and the action of the cross groove, so that the polished stainless steel fastener passes through the rubber plate 63 and falls into the discharge groove 21, and then the polished stainless steel fastener is discharged along the discharge groove 21;

[0043] After the discharge, the rubber plate 63 is restored to its original state, and the stainless steel fastener is again limited in the polishing structure, so that the rubber plate 63 is used to limit the stainless steel fastener in the polishing structure formed by the multiple polishing wheels 67, and the stainless steel fastener can be effectively discharged, effectively reducing the probability of incomplete polishing of the stainless steel fastener due to factors such as discharge, and effectively ensuring the polishing effect and efficiency;

[0044] In addition, the annular pressure plate 631 can be pulled downward to compress the multiple elastic members 632, so that the multiple elastic members 632 generate elastic force, and at the same time the annular pressure plate 631 is separated from the rubber plate 63, thereby releasing the restriction on the rubber plate 63, and then the rubber plate 63 is taken out of the groove, and a new rubber plate 63 is put back into the groove, and then the annular pressure plate 631 is released, and under the elastic force of the multiple elastic members 632, the annular pressure plate 631 is moved up and re-fitted with the lower end of the lower annular plate 64, and the rubber plate 63 is restricted and installed in the groove again, so that the rubber plate 63 can be easily disassembled and assembled, and the probability of incomplete polishing of the polished stainless steel fasteners due to factors such as loss is effectively reduced, and the polishing effect and efficiency are effectively guaranteed.

[0045] Although this specification is described according to implementation modes, not every implementation mode includes only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
