[0009] The locking member comprises a stud fixed on the end surface of the roller cutter barrel seat, a clamping plate is arranged at the outer end of the stud, and the clamping plate is clamped on the outer end surface of the temperature regulating annular plate.

[0010] The outer end surface of the temperature regulating annular plate is provided with a through hole, and a rubber plug is provided in the through hole.

[0011] The fixed blade teeth and the adjusting blade teeth are provided with wear-resistant coatings on the outside.

[0012] The beneficial effects of the present invention are as follows: the present invention not only has fixed teeth, which can process sparser heat sink fins, but also can utilize adjustment plates to install adjustable teeth between the fixed teeth to process denser heat sink fins. The present invention is easy to install and disassemble, has various processing types, and is more practical. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] The following is a detailed description of the embodiments of the present invention with reference to the accompanying drawings. DETAILED DESCRIPTION

[0019] The present invention will be further described below in conjunction with the accompanying drawings and embodiments:

[0020] like Figures 1 to 4 As shown, an adjustable hob for processing automobile air-conditioning radiating fins comprises a hob shaft 1, a hob barrel seat 2 is provided on the outer fixed sleeve of the hob shaft 1, a plurality of fixed blade teeth 3 are evenly distributed on the circumference of the outer wall of the hob barrel seat 2, an adjustment plate 4 is detachably mounted on one end surface of the hob barrel seat 2, a plurality of adjustment blade teeth 5 are provided on the side surface of the adjustment plate 4 facing the hob barrel seat 2, and the adjustment blade teeth 5 are distributed between two adjacent fixed blade teeth 3.

[0021] Particularly, the adjustment plate 4 is an integral annular plate, which is sleeved on the hob shaft 1 and locked on the end surface of the hob cylinder seat 2 by means of fixing bolts 6 .

[0022] Particularly, the adjustment plates 4 are two sector-shaped plates docked on the hob shaft 1 , and the adjustment plates 4 are locked on the end surface of the hob cartridge seat 2 by fixing bolts 6 .

[0023] The cutter barrel seat 2 is provided with an annular slot 7 on the end face opposite to the adjustment plate 4, and a temperature regulating annular plate 8 is inserted into the annular slot 7. A cavity is provided in the temperature regulating annular plate 8 and the cavity is filled with phase change medium. The temperature regulating annular plate 8 is fixed to the end face of the cutter barrel seat 2 by a locking piece.
