[0026] The technical solutions in the embodiments of the utility model will be apparently and completely described in connection with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. The embodiments in the application and the features in the embodiments can be combined with each other without conflict. Based on the embodiments in the utility model, all other embodiments obtained by the ordinary skilled in the art without creative labor belong to the protection scope of the utility model.

[0027] Please refer to Figures 1-6 The utility model discloses a cutting machine hobbing cutter, including:

[0028] Roller body 1, roller body 1 can be detachably arranged on the cutting machine roller, can rotate synchronously with the cutting machine roller, and a plurality of annularly distributed blade mounting grooves are formed in the roller body 1.

[0029] A plurality of blades 2, a plurality of blades 2 can be detachably arranged in each blade mounting groove of the roller body 1.

[0030] A plurality of push components 3, the push component 3 can be detachably arranged on the roller body 1, and is used for pushing the cutting edge of the corresponding blade 2 to move away from the roller body 1 side.

[0031] Positioning assembly 4, positioning assembly 4 can be detachably arranged on the roller body 1, and is located in the moving area of the blade 2 cutting edge, and the positioning assembly 4 is used for limiting the moving distance of each blade 2, so that the spacing between the cutting edge of each blade 2 and the axis of the roller body 1 remains consistent.

[0032] The utility model discloses a cutting machine hobbing cutter, including:

[0033] In an embodiment, the push component 3 is composed of a push block 31 and a first screw 32 penetrating through the push block 31 and threadedly connected with the roller body 1.

[0034] The blade 2 is provided with an insertion slot on the side away from the blade 2 cutting edge, and the insertion slot is provided with an inclined surface capable of pushing the blade 2 to move away from the roller body 1 side when the push block 31 approaches the blade 2 side.

[0035] In this way, the design utilizes the restriction of the pushing block 31, so that when the blade 2 is pushed by the pushing block 31, the blade 2 can only move away from the roller body 1, and meanwhile, due to the inclined surface, the blade 2 with machining error can also be pushed by the pushing block 31, so that the machining precision requirement of the blade 2 can be reduced, and the purchase cost is reduced.

[0036] In specific operation, first, the blade 2 is placed on the roller body 1, then the pushing block 31 is installed into the slot, and then the first screw 32 is used to connect the pushing block 31 and the blade 2, and then during the tightening of the first screw 32, the first screw 32 pushes the pushing block 31 to be close to the roller body 1, so that the pushing block 31 presses the inclined surface of the blade 2, so that the blade 2 moves away from the roller body 1 under the restriction of the pushing block 31, until the blade 2 is blocked by the positioning assembly 4 and cannot continue to move.

[0037] In an embodiment, the blade 2 is detachably provided with at least one second screw 5 which is threadedly connected with the roller body 1, and a sliding groove is formed in the blade 2 for sliding of the second screw 5 when the blade 2 is pushed by the pushing block 31.

[0038] In this way, the second screw 5 is first connected with the roller body 1 through the sliding groove, so that the blade 2 is prevented from being completely separated from the roller body 1 during the debugging process, and after the debugging of the blade 2 is completed, the second screw 5 can be tightened to further position the blade 2.

[0039] In an embodiment, the positioning assembly 4 includes two mounting discs 41 which are detachably arranged at both ends of the roller body 1, two sleeve rings 42 which are respectively sleeved with the two mounting discs 41, and a plurality of connecting rods 43 which connect adjacent mounting discs 41 and sleeve rings 42, and one end of the sleeve ring 42 close to the roller body 1 is located in the area where the blade 2 moves away from the roller body 1.

[0040] In this way, after the mounting disc 41 is connected with the roller body 1 through the third screw, one end of the sleeve ring 42 can be located in the area where the blade 2 moves away from the roller body 1, so that each blade 2 can be positioned and adjusted by moving to abut against the sleeve ring 42, and the maintenance personnel can quickly determine whether the blade 2 is adjusted in place.

[0041] It should be noted that when the positioning assembly 4 is connected with the roller body 1, the blade 2 can be inserted or removed from the end of the roller body 1 without being hindered by the positioning assembly 4.

[0042] In an embodiment, a positioning groove is formed in the sleeve ring 42 for insertion of the blade 2, and a positioning surface is arranged in the positioning groove for abutting against the inclined surface of the blade 2.

[0043] In this way, the positioning surface abutting against the inclined surface of the blade 2 is used to position the blade 2, so that the blade 2 is not abraded during the positioning process, and the cutting effect of the blade 2 is not affected.

[0044] In the embodiment, the positioning slot on one of the collars 42 is a through slot, and the positioning slot on the other collar 42 is a non-through slot, so that the blade 2 can be moved from one end of the collar 42 provided with the through slot to the roll body 1 and abut against the collar 42 provided with the non-through slot, thereby achieving the effect of quickly positioning the blade 2 moved to the roll body 1.

[0045] It should be noted that if the embodiments of the present application involve directional indications (such as up, down, left, right, front, back, etc.), the directional indications are only used to explain the relative positional relationship, movement condition, etc. between the components in a certain specific posture (as shown in the drawings), and if the specific posture changes, the directional indications will also change accordingly.

[0046] In addition, if the embodiments of the present application involve descriptions of "first", "second", etc., the descriptions of "first", "second", etc. are only for description purposes, and cannot be understood as indicating or implying the relative importance or implicitly indicating the number of the indicated technical features.
