[0033] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0034] First Embodiment

[0035] like Figures 1-5 As shown, a modular cylindrical wheel is used for slab thickness leveling and other processing. The modular cylindrical wheel includes a base 10 and a cutter head 20. The base 10 is generally cylindrical in shape. Several slots 103 are integrally formed on the outer surface of the base 10. Each slot 103 extends along the axial direction of the base 10. The slots 103 are circumferentially equidistant on the outer surface of the base 10. The surfaces between several adjacent slots 103 also form a cylindrical surface.

[0036] The base 10 has a positioning end 101 and a locking end 102. The positioning end 101 of the base 10 is provided with a positioning plate 104, and the locking end 102 of the base 10 is provided with an end plate 30. Both the positioning plate 104 and the end plate 30 are circular ring plates.

[0037] Specifically, the positioning plate 104 is integrally formed and fixed to the positioning end 101 of the base 10, and the diameter of the positioning plate 104 is larger than the diameter of the base 10, so that the positioning plate 104 can block the slot 103 from extending to one end of the positioning end 101. The locking end 102 of the base 10 has several mounting holes 1021 on its end face, and the end plate 30 has several connecting holes 301 on its end face. When the end plate 30 is installed on the base 10, the connecting holes 301 of the end plate 30 are aligned with the mounting holes 1021 and screwed together to detachably mount the end plate 30 to the locking end 102 of the base 10. Furthermore, the diameter of the end plate 30 is larger than the diameter of the base 10. Of course, the cutter head 20 is first installed on the slot 103 of the base 10, the positioning plate 104 limits one end of the cutter head 20, and then the end plate 30 is locked to the locking end 102 of the base 10 and the cutter head 20 is pressed so that the cutter head 20 can be securely and detachably assembled on the outer surface of the base 10.

[0038] More specifically, the outer side of the tool head 20 is a machining surface 201, and the inner side of the tool head 20 is a connecting surface 202, and the clamping seat 21 is arranged on the connecting surface 202 of the tool head 20. The clamping seat 21 has an assembly surface 211 and a clamping head 212, and the clamping head 212 is integrally formed with the assembly surface 211. The assembly surface 211 of the clamping seat 21 matches the connecting surface 202 of the tool head 20, so that the clamping seat 21 is connected to the connecting surface 202 through the assembly surface 211, and the clamping seat 21 is fixed on the tool head 20.

[0039] When the tool head 20 is installed, the clamping head 212 of the tool head 20 is assembled into the clamping groove 103 along the extension direction of the clamping groove 103. Since the slot width W1 of the clamping groove 103 is smaller than the end width W2 of the clamping head 212 of the clamping seat 21, a dovetail type connection is formed between the clamping head 212 and the clamping groove 103. In addition to the dovetail type connection, a T type connection can also be arranged between the clamping head and the clamping groove.

[0040] After the clamping head 212 is assembled into the clamping groove 103, since the opening direction of the clamping groove 103 on the base 10 is perpendicular to the axial direction of the base 10, the clamping seat 21 can offset the centrifugal force generated during the rotation of the cylindrical wheel, and can prevent the clamping head 212 from being separated from the clamping groove 103 in the radial direction of the base 10. In addition, the end of the clamping head 212 of the clamping seat 21 is in close contact with the groove bottom of the clamping groove 103, so that the assembly between the clamping head 212 and the clamping groove 103 is more secure, and gaps are avoided to prevent the tool head 20 from loosening during machining of the product.

[0041] Preferably, a plurality of water grooves 2011 are integrally formed on the machining surface 201 of the tool head 20. The water grooves 2011 are arranged obliquely along the machining direction of the tool head 20, and the plurality of water grooves 2011 are arranged along the assembly direction of the tool head 20. Therefore, by arranging a plurality of water grooves 2011 on the machining surface of the tool head 20, the chip removal effect and the cooling effect of the tool head 20 can be improved.

[0042] If necessary, the clamping groove 103 is arranged to extend along the circumferential direction of the base 10, and at this time, a plurality of clamping grooves 103 are arranged along the axial direction of the base 10. Alternatively, the clamping groove 103 is arranged to extend obliquely on the outer surface of the base 10, so that the clamping groove 103 forms a certain angle with the axial direction of the base 10.

[0043] In this way, the embodiment of the present application provides a modular cylindrical wheel. A plurality of clamping grooves 103 extending in the axial direction are arranged on the outer surface of the base 10, and the tool head 20 with the clamping seat 21 is arranged. The clamping seat 21 of the tool head 20 is assembled into the clamping groove 103 along the extension direction of the clamping groove 103, and then the tool head 20 is detachably assembled on the outer surface of the base 10. The two ends of the clamping seat 21 are defined by the positioning plate 104 and the end plate 30, and the modular cylindrical wheel is formed in this way.
