Description

Technical Field

[0001] The utility model relates to the technical field of mechanical equipment, in particular to an integrated guide wheel. Background Art

[0002] like Figure 1 As shown, the guide wheel 11 (polymer wear-resistant guide wheel 11) currently used by the company is connected to the dust cover 13 in a split type. During assembly, the bolt 12 (M5*25 hexagon socket bolt 12) is passed through the holes of the dust cover 13 (stainless steel material) and the guide wheel 11 in turn and connected to the guide wheel shaft, and then the bolt 12 is tightened with an hexagonal wrench to achieve the mechanical connection between the dust cover 13, the guide wheel 11 and the guide wheel shaft. During replacement, the three M5*25 hexagon socket bolts 12 must be unscrewed and removed first, and then the stainless steel dust cover 13 must be removed, and then the old guide wheel 11 must be removed, and a new guide wheel must be taken, and the guide wheel center hole 111 of the new guide wheel must be aligned with the guide wheel shaft and adjusted to be coaxial and pushed to the bottom, and then the guide wheel fixing hole 112 (round hole) must be aligned with the guide wheel shaft threaded hole, and then the dust cover fixing hole 131 must be aligned with the guide wheel fixing hole 112, and finally the bolt 12 must be put into the guide wheel shaft threaded hole and tightened in sequence.

[0003] It can be seen that the existing split guide wheel 11 has the following disadvantages:

[0004] 1. The threaded hole of the guide wheel shaft, the guide wheel fixing hole 112, and the dust cover fixing hole 131 must be aligned before inserting the bolt 12. During this period, the dust cover 13 needs to be rotated several times to adjust the coaxiality of the above three holes. The replacement process is complicated and inefficient.

[0005] 2. During squaring / grinding cutting, silicon powder will enter the threaded hole of the guide wheel shaft in a gaseous state. The guide wheel 11 needs to be replaced every 10 days. Due to frequent unscrewing (completely unscrewing) and tightening of the bolt 12, the thread of the guide wheel shaft threaded hole and the bolt 12 may slip from time to time, making disassembly and assembly difficult.

[0006] 3. When the threaded hole of the guide wheel shaft slips, the shaft needs to be replaced, resulting in increased costs.

[0007] The information disclosed in this background technology section is only intended to deepen the understanding of the overall background technology of the present invention, and should not be regarded as an admission or any form of implication that the information constitutes the prior art known to those skilled in the art.

[0043] Example

[0044] See also Figure 1 to Figure 3 This embodiment provides an integrated guide wheel, including a wheel body 2, a center hole, a connecting ring 4, a dust cover 5 and a waist-shaped hole 6.

[0045] The wheel body 2 is the main structure of the integrated guide wheel; a plurality of (6) weight-reducing holes 21 are evenly distributed on the wheel body 2.

[0046] The center hole is located in the middle of the wheel body 2 ( Figure 2 In the figure, the center hole is blocked by a dust cover 5), the center hole matches the guide wheel shaft (not shown); the guide wheel shaft has a threaded hole.

[0047] The connecting ring 4 is fixed on one side of the wheel body 2 and is coaxial with the center hole; the inner diameter of the connecting ring 4 is larger than the diameter of the center hole.

[0048] The dust cover 5 is made of plastic instead of stainless steel. One end edge of the dust cover 5 is extended outward to form a flange 51, and the flange 51 is integrally connected to the connecting ring 4 by welding or the like; the arrangement of the flange 51 and the connecting ring 4 facilitates the integral connection of the dust cover 5 and the wheel body 2.

[0049] The waist-shaped hole 6 passes through the flange 51 and the connecting ring 4, and the bolt used to connect the integrated guide wheel and the guide wheel shaft can pass through the waist-shaped hole 6 and connect with the threaded hole; the waist-shaped hole 6 includes a through hole 61 and a mounting hole 62 located at its two ends, and the through hole 61 and the mounting hole 62 are connected to each other, and the head of the bolt can pass through the through hole 61 but cannot pass through the mounting hole 62; there are multiple waist-shaped holes 6, and the multiple (three) waist-shaped holes 6 are evenly distributed on the wheel body 2.

[0050] In a specific implementation scenario, the bolt is an M5 bolt, the diameter of the through hole 61 is 6 mm, and the mounting hole 62 is a ø9.2 mm countersunk hole.

[0051] When installing the integrated guide wheel, proceed as follows:

[0052] Step S1, use an Allen wrench to turn the bolt on the guide wheel shaft counterclockwise and unscrew the bolt 3~5mm;

[0053] Step S2, align the through hole 61 on the wheel body 2 with the bolt, and push the wheel body 2 onto the guide wheel shaft with both hands; during this process, the bolt can pass through the through hole 61 on the wheel body 2;

[0054] Step S3, rotating the wheel body 2 so that the bolt moves relative to the wheel body 2 to the mounting hole 62;

[0055] Step S4: Use an Allen wrench to turn the bolt on the guide wheel shaft clockwise to fix the wheel body 2, thereby installing the integrated guide wheel on the guide wheel shaft.

[0056] In combination with the above content, this embodiment has at least the following beneficial effects:

[0057] 1. By improving the original split structure composed of the guide wheel and the dust cover 5 into the integrated structure of the integrated guide wheel in this embodiment, and at the same time, improving the original round holes on the guide wheel and the dust cover 5 into waist-shaped holes 6, when installing or replacing the integrated guide wheel, the operator does not need to completely unscrew or unscrew the bolts from the guide wheel shaft, which simplifies the replacement process and makes the replacement of the integrated guide wheel more convenient and efficient.

[0058] Second, since there is no need to completely unscrew the bolt (the bolt unscrewing length is reduced), the probability of thread stripping in the threaded hole and the bolt is reduced, the number of guide wheel shaft replacements is reduced, and the spare parts cost is reduced.

[0059] 3. The wheel body 2 and the dust cover 5 adopt an integrated structure. At the same time, the dust cover 5 adopts plastic instead of the original stainless steel material, which reduces the overall weight and the moment of inertia. The integrated guide wheel has higher dynamic balancing accuracy and better synchronization with the linear speed of the main roller (the equipment connected to the guide wheel shaft transmission).
