DETAILED DESCRIPTION

[0021] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with specific embodiments.

[0022] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, a diamond wire slicing guide wheel comprises a guide wheel 1 and bearing bases 2 on both sides of the guide wheel 1, the guide wheel 1 is a hollow structure, the bearing base 2 is liftable, and a support plate 3 is detachably mounted on the top of the bearing base 2, a crystal holder 4 is fixedly mounted on the top of the support plate 3, a guide wheel shaft 5 is rotatably mounted inside the bearing base 2, and a connecting structure 6 is arranged between the guide wheel shaft 5 and the guide wheel 1;

[0023] The connection structure 6 includes a backing plate 7 fixedly mounted at one end of the guide wheel shaft 5, a guide wheel bracket 8 is slidably mounted inside the backing plate 7, a slide groove 13 for accommodating the sliding of the guide wheel bracket 8 is provided inside the backing plate 7, the guide wheel bracket 8 is circumferentially distributed, a guide wheel disc 11 is rotatably mounted at the center of the backing plate 7, an arc groove 10 is provided inside the guide wheel disc 11, and a hexagon socket bolt 12 penetrates the guide wheel disc 11 and the center of the backing plate 7;

[0024] A clamping column 9 is installed on one side of the guide wheel bracket 8, and the clamping column 9 runs through the arc groove 10.

[0025] In this embodiment, when it is necessary to disassemble the guide wheel 1, the bearing base 2 and the support plate 3 are disassembled, and the connecting structure 6 at one end of the guide wheel shaft 5 is separated in parallel with the guide wheel 1. When a different guide wheel 1 needs to be installed, the hexagon socket bolt 12 is loosened and the guide wheel disc 11 is rotated forward. The inclined arc groove 10 in the guide wheel disc 11 rotates accordingly, driving the clamping column 9 on the guide wheel bracket 8 to move accordingly. The surrounding guide wheel brackets 8 shrink at the same time inside the pad 7 to reduce the diameter. The guide wheel disc 11 is rotated reversely, and the guide wheel bracket 8 slides inside the pad 7 to expand the diameter. The inner diameter of the guide wheel 1 to be replaced is adjusted. After adjustment, the guide wheel bracket 8 is close to the inner wall of the guide wheel 1. After the connecting structures 6 at both ends of the guide wheel shaft 5 are clamped, the bearing base 2 and the support plate 3 are installed, so that guide wheels of different sizes can be quickly replaced, and the applicability is wide.

[0026] As an implementation method, Figure 1 , Figure 2 and Figure 3As shown, the connection structure 6 is arranged in a mirror-symmetrical manner with respect to the center position of the support plate 3 , and one end of the guide wheel shaft 5 is installed at the center of the connection structure 6 .

[0027] In this embodiment, after the connection structures 6 at both ends of the guide wheel shaft 5 are clamped, the guide wheel 1 in the guide wheel shaft 5 does not deviate. When the guide wheel 1 and the connection structure 6 rotate, the guide wheel shaft 5 is driven to rotate in the bearing base 2, and the stability is good.

[0028] As an implementation method, Figure 4 As shown, the arc grooves 10 are arranged in a circumferential distribution with the center of the guide wheel disc 11 as the standard, and the arc grooves 10 are at least six groups.

[0029] In this embodiment, when the guide wheel disc 11 rotates, the arc groove 10 rotates with the center of the guide wheel disc 11, thereby driving the clamping column 9 and the guide wheel bracket 8 inside the arc groove 10 to move. The arrangement of multiple groups of arc grooves 10 can make the guide wheel bracket 8 fit the inner diameter of the guide wheel 1.

[0030] As an implementation method, Figure 4 As shown, the top end of the guide wheel bracket 8 is arranged in an arc shape, and a rubber pad is arranged on the outer side of the guide wheel bracket 8.

[0031] In this embodiment, the rubber pad outside the arc-shaped guide wheel bracket 8 contacts the inner diameter of the guide wheel 1 to increase friction, and the slide groove 13 inside the pad 7 ensures that the clamping column 9 on the guide wheel bracket 8 is affected by the arc groove 10, and the guide wheel bracket 8 moves divergently, which is suitable for guide wheels 1 of different diameters.

[0032] As an implementation method, Figure 4 As shown, the pad 7 is a disc structure, the diameter of the pad 7 is larger than the diameter of the guide wheel 1, and the guide wheel shaft 5, the pad 7 and the guide wheel disc 11 are coaxially arranged.

[0033] In this embodiment, a circular pad 7 is used. When the guide wheel 1 is engaged with the connection structure 6 , both ends of the guide wheel 1 contact the pad 7 to prevent the guide wheel 1 from moving during rotation.

[0034] As an implementation method, Figure 4 As shown, the arc groove 10 corresponds to the clamping column 9, and the arc groove 10 is inclined. Through the inclined arc groove 10, when the guide wheel disc 11 rotates, the inclined arc groove 10 can drive the clamping column 9 to move, and the clamping column 9 drives the guide wheel bracket 8 to move along the slide groove 13.

[0035] Working principle: When the guide wheel 1 needs to be disassembled during use, the bearing base 2 and the support plate 3 are disassembled, and the connecting structure 6 at one end of the guide wheel shaft 5 is separated from the guide wheel 1 in parallel;

[0036] When a different guide wheel 1 needs to be installed, the guide wheel disc 11 is rotated by loosening the hexagon socket bolt 12, and the arc groove 10 in the guide wheel disc 11 rotates accordingly, driving the clamping column 9 on the guide wheel bracket 8 to move accordingly, and the surrounding guide wheel brackets 8 move simultaneously inside the pad 7, thereby changing the diameter, and adjusting the inner diameter of the guide wheel 1 to be replaced according to the need. After adjustment, the guide wheel bracket 8 is close to the inner wall of the guide wheel 1, and the connecting structures 6 at both ends of the guide wheel shaft 5 are clamped, and the bearing base 2 and the support plate 3 are installed, so that guide wheels of different sizes can be quickly replaced.

Under the concept of the present invention, the technical features in the above embodiments or different embodiments may be combined, the steps may be implemented in any order, and there are many other variations of the different aspects of the present invention as described above, which are not provided in detail for the sake of simplicity.
