Description

Technical Field

[0001] The utility model relates to the technical field of rollers, and particularly relates to a riveted double-edge roller baffle plate. Background Art

[0002] At present, there are three manufacturing processes for conventional double-edge roller baffle plates, including integral type, screwed type and welded type. Among them, the integral blank processing has a long cycle and high labor cost, while the screwed type increases the processing of threaded holes and baffle holes and a large number of screw fastening processes during assembly. The welded type requires reserved machining allowance after welding, has high requirements for the professional quality of personnel, and also requires a dedicated welding area. Therefore, there is an urgent need for a new baffle plate that is convenient to process and does not require threaded assembly. Content of the Utility Model

[0003] The purpose of the utility model is to provide a riveted double-edge roller baffle plate to solve the problems existing in the above-mentioned prior art.

[0004] The above technical purpose of the utility model is achieved through the following technical solutions:

[0005] A riveted double-edge roller baffle plate includes a wheel body and special-shaped rivets. The axis of the wheel body is horizontally arranged from left to right. A through hole is arranged at the middle position on the left side of the wheel body. A first convex ring is integrally formed on the left side of the wheel body, and a second convex ring is integrally formed on the right side of the wheel body. A rubber ring is sleeved on the wheel body. The first convex ring and the second convex ring are both coaxially arranged with the wheel body. A first retaining ring is sleeved on the first convex ring, and a plurality of first positioning holes are axially and equally spaced at the left end of the first convex ring. A second retaining ring is sleeved on the second convex ring, and a plurality of second positioning holes are axially and equally spaced at the right end of the second convex ring. The first retaining ring and the second retaining ring are both fixedly connected to the wheel body through special-shaped rivets;

[0006] The special-shaped rivet includes a fixing ring and a plurality of positioning columns. The fixing ring on the left side of the wheel body is arranged along the gap between the first retaining ring and the first convex ring. The outer diameter of the fixing ring on the left side of the wheel body is greater than the inner diameter of the first retaining ring. A plurality of first positioning columns are axially and equally spaced on the right side of the fixing ring on the left side of the wheel body. The positions of the plurality of first positioning columns correspond to the positions of the plurality of first positioning holes one by one. The fixing ring on the right side of the wheel body is arranged along the gap between the second retaining ring and the second convex ring. The outer diameter of the fixing ring on the right side of the wheel body is greater than the outer diameter of the second retaining ring. A plurality of second positioning columns are axially and equally spaced on the left side of the fixing ring on the right side of the wheel body. The positions of the plurality of second positioning columns correspond to the positions of the plurality of second positioning holes one by one.

[0007] By adopting the above technical solution, the special-shaped rivet eliminates the need for additional processing of the retaining ring on the wheel body, such as machining screw holes or time-consuming integral machining, and has a low requirement for the professional quality of personnel. There is no need to master advanced welding techniques. It only requires fixing the wheel body in the fixture and aligning the positioning post at the bottom of the special-shaped rivet with the positioning hole on the wheel body. At this time, the outer diameter of the fixing ring of the special-shaped rivet is larger than the inner diameter of the first retaining ring, that is, the fixing ring will cover both the first retaining ring and the first convex ring simultaneously. By riveting the special-shaped rivet, the fixing of the retaining ring can be completed. The riveting has high efficiency and good stability, and also eliminates the consumption of welding gas and thread glue.

[0008] In a further embodiment, the diameters of the plurality of first positioning holes on the first convex ring on the left side of the wheel body gradually increase from left to right, and the diameters of the plurality of second positioning holes on the second convex ring on the right side of the wheel body gradually increase from right to left.

[0009] By adopting the above technical solution, the original diameter of the positioning hole is slightly larger than that of the positioning post. However, during the riveting process, the positioning post will deform and fit more tightly with the positioning hole. At this time, if the entrance of the positioning hole is narrow, the deformed positioning post will be firmly stuck in the positioning hole, which more effectively fixes the baffle and further improves the quality of the roller.

[0010] In a further embodiment, the through hole is composed of a first hole section, a second hole section, and a third hole section. The first hole section, the second hole section, and the third hole section are arranged in sequence from left to right. The diameter of the first hole section is larger than that of the second hole section, and a chamfer is provided on the left side of the first hole section. The diameter of the second hole section is larger than that of the third hole section, and a chamfer is provided on the right side of the second hole section.

[0011] By adopting the above technical solution, the chamfers at the first hole section and the second hole section are mainly for facilitating the installation of the motor shaft, enabling the motor shaft to quickly pass through the through hole and drive the rotation of the roller.

[0012] In a further embodiment, an acute angle chamfering structure is provided on the outer edge of the right side of the first retaining ring, and an acute angle chamfering structure is provided on the outer edge of the left side of the second retaining ring.

[0013] By adopting the above technical solution, the acute angle chamfering structures on the first retaining ring and the second retaining ring can form a space for accommodating the guide rail between them, making the roller more stable during rotation on the guide rail and preventing situations such as skewing during high-speed rotation.

[0014] In a further embodiment, the thicknesses of both the first retaining ring and the second retaining ring are between 3 mm and 10 mm.

[0015] By adopting the above technical solution, the thickness of 3mm - 10mm covers the vast majority of retaining rings on the market, expanding the scope of the present utility model to single-sided or double-sided baffle structures with various outer diameter sizes.

[0016] In a further embodiment, the inner diameter of the fixing ring is consistent with the aperture diameter at the left end of the first hole section.

[0017] By adopting the above technical solution, while fixing the first retaining ring and the first convex ring, the fixing ring will not interfere with the setting of the motor shaft.

[0018] In summary, the present utility model has the following beneficial effects:

[0019] 1. Through the arrangement of the special-shaped rivets and the convex rings, the retaining rings provided on the convex rings can be riveted and fixed. Riveting requires lower quality requirements for personnel. At the same time, the difficulty of processing special-shaped rivets is lower than that of processing an integral hub, which can achieve the effects of convenient processing and higher efficiency;

[0020] 2. Through the arrangement of the rubber ring, the wheel body can be avoided from contacting the guide rail. The rubber ring can serve as a buffer during the process of the motor shaft driving the wheel body to rotate at high speed, reducing vibration and increasing the friction between the wheel body and the guide rail at the same time, achieving the effect of extending the service life of the roller.

[0026] Embodiment:

[0027] As Figure 1 - Figure 2 shown, a riveted double-edge roller baffle includes a wheel body 1 and a special-shaped rivet 2. The axis of the wheel body 1 is horizontally arranged from left to right. A through hole is provided at the middle position on the left side of the wheel body 1. A first convex ring 3 is integrally formed on the left side of the wheel body 1. A second convex ring 4 is integrally formed on the right side of the wheel body 1. A rubber ring is sleeved on the wheel body 1. Both the first convex ring 3 and the second convex ring 4 are coaxially arranged with the wheel body 1. A first retaining ring 5 is sleeved on the first convex ring 3. A plurality of first positioning holes are axially and equally spaced at the left end of the first convex ring 3. A second retaining ring 6 is sleeved on the second convex ring 4. A plurality of second positioning holes are axially and equally spaced at the right end of the second convex ring 4. The thicknesses of both the first retaining ring 5 and the second retaining ring 6 are between 3 mm and 10 mm. Both the first retaining ring 5 and the second retaining ring 6 are fixedly connected to the wheel body 1 through the special-shaped rivet 2. The special-shaped rivet 2 includes a fixing ring 21 and a plurality of positioning columns. The inner diameter of the fixing ring 21 is the same as the aperture at the left end of the first hole section 7. The fixing ring 21 on the left side of the wheel body 1 is arranged along the gap between the first retaining ring 5 and the first convex ring 3. The outer diameter of the fixing ring 21 on the left side of the wheel body 1 is greater than the inner diameter of the first retaining ring 5. A plurality of first positioning columns 22 are axially and equally spaced on the right side of the fixing ring 21 on the left side of the wheel body 1. The positions of the plurality of first positioning columns 22 correspond one by one to the positions of the plurality of first positioning holes. The fixing ring 21 on the right side of the wheel body 1 is arranged along the gap between the second retaining ring 6 and the second convex ring 4. The outer diameter of the fixing ring 21 on the right side of the wheel body 1 is greater than the outer diameter of the second retaining ring 6. A plurality of second positioning columns 23 are axially and equally spaced on the left side of the fixing ring 21 on the right side of the wheel body 1. The positions of the plurality of second positioning columns 23 correspond one by one to the positions of the plurality of second positioning holes. Through the arrangement of the special-shaped rivet 2, the retaining rings arranged on the convex rings of the wheel body 1 can be fixed through the special-shaped rivet 2. Compared with screw connection, the special-shaped rivet 2 does not require additional machining of screw holes on the retaining rings, and has a wide applicability. The retaining rings with a thickness of 3 mm - 10 mm cover most of the specifications of the retaining rings on the market. At the same time, the processing time of the special-shaped screw is short, and the man-hours consumed are lower than those of an integral hub. It is not as demanding on personnel as welding, and general workers with short-term training can properly operate simple jigs and riveting presses, which greatly reduces the processing cost and improves the processing efficiency. At the same time, the quality of the produced wheel body 1 is better.

[0028] As Figure 1 - Figure 2 shown, the apertures of the multiple first positioning holes on the first convex ring 3 on the left side of the wheel body 1 gradually increase from left to right, and the apertures of the multiple second positioning holes on the second convex ring 4 on the right side of the wheel body 1 gradually increase from right to left. The through hole is composed of a first hole section 7, a second hole section 8, and a third hole section 9. The first hole section 7, the second hole section 8, and the third hole section 9 are arranged in sequence from left to right. The aperture of the first hole section 7 is larger than that of the second hole section 8. A chamfer is provided on the left side of the first hole section 7. The aperture of the second hole section 8 is larger than that of the third hole section 9. A chamfer is provided on the right side of the second hole section 8. An acute angle blunt structure is provided on the outer edge of the right side of the first retaining ring 5, and an acute angle blunt structure is provided on the outer edge of the left side of the second retaining ring 6. Through the multiple chamfers on the through hole, the wheel body 1 can be sleeved on the rotating shaft of the motor. The chamfers can facilitate the setting of the rotating shaft more conveniently. The reason for the change in the aperture of the positioning hole is that during the riveting process, the positioning post will deform under the action of pressure and fit more closely with the positioning hole. If the aperture of the bottom of the positioning hole is larger than that of the top, then after the deformation is completed, the positioning post will form a shape that is difficult to pull out, so that the retaining ring can be permanently fixed on the wheel body 1, which greatly improves the overall service life of the roller.

[0029] Specific implementation process: First, set the convex ring of the wheel body 1 upward, then fix it on the fixture, place the fixture under the riveting machine. First, sleeve the rubber ring. After the rubber ring is sleeved, install the retaining ring upward. Note that the side of the convex ring with the acute angle blunt structure is set downward. At this time, set the positioning post of the special-shaped rivet 2 downward and align it with the positioning hole on the convex ring. After setting the special-shaped rivet 2, start the riveting machine. The riveting machine fixes the retaining ring on the convex ring through the special-shaped rivet 2. Loosen the fixture, turn over the wheel body 1, and put on the second retaining ring 6. Then set the special-shaped rivet 2 and carry out riveting. After the riveting is completed, the wheel body 1 is processed.

For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; "connection" can be a direct connection or an indirect connection through an intermediate medium. For those of ordinary skill in the art, the specific meanings of the above terms in the embodiments disclosed in the present utility model can be understood according to specific situations.

[0031] This specific embodiment is only an explanation of the present utility model, and it is not a limitation of the present utility model. Those skilled in the art can make modifications without creative contributions to this embodiment according to needs after reading this specification, but as long as it is within the scope of the claims of the present utility model, it is protected by the patent law.
