Description

Technical Field

[0001] The utility model belongs to the field of milling processing, and particularly relates to a positioning structure for milling cutter processing. Background Technique

[0002] As a rotary cutting tool for milling processing, a milling cutter performs milling through multiple cutting teeth on the milling cutter. During the installation process of the milling cutter, it is necessary to install the milling cutter on the mounting head of the milling machine through a positioning device for fixation, and the mounting head of the milling machine drives the positioning device and the milling cutter to rotate for work.

[0003] There is a prior positioning structure for milling cutter processing (CN221210024U). By passing a locking screw through a cover plate and a rotating ring and then connecting a positioning block, the cover plate is fixed on the positioning block, and the position of the milling cutter blade can be fixed to prevent the milling cutter blade from falling off during work. Since the fixing part on the arc-shaped insertion block for fixing the milling cutter is relatively weak, during the high-speed rotation of the milling cutter, the milling cutter is prone to looseness, affecting the milling effect. In severe cases, the milling cutter may fly out, causing safety accidents. At the same time, when replacing the cutter blade, it is necessary to operate each reinforcement mechanism for maintaining the fixed state separately, which is not only cumbersome but also affects the efficiency of replacing the cutter blade. Therefore, a positioning structure for milling cutter processing is proposed to solve the above-mentioned problems. Summary of the Utility Model

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0022] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without making creative efforts belong to the protection scope of the present utility model.

[0023] Please refer to Figures 1-4 , in the milling cutter processing and positioning structure of this embodiment, through the provided reinforcement member 6, fixing member 5 and driving member 4, the quick disassembly and assembly of the milling cutter blade 3 can be realized. At the same time, compared with the technical solution in the comparative document, the stability of the fixing of the milling cutter blade 3 can be improved, and the milling cutter blade 3 can be prevented from loosening or flying out during use.

[0024] Specifically, it includes a carrier plate 1, and a plurality of fixing grooves 2 are formed inside the carrier plate 1;

[0025] A plurality of milling cutter blades 3 respectively slide through the corresponding fixing grooves 2, and a fixing hole 31 is formed in the middle of the milling cutter blade 3;

[0026] The driving member 4 is arranged in the middle of the carrier plate 1;

[0027] A plurality of fixing members 5 are respectively arranged in the corresponding fixing grooves 2 and penetrate through the fixing holes 31 on the opposite milling cutter blades 3 to fix the milling cutter blades 3;

[0028] Each fixing member 5 is connected to the driving member 4, and the driving member 4 is used to drive each fixing member 5;

[0029] Two reinforcement members 6 are arranged in the carrier plate 1 and located in the inner cavity of the driving member 4, and are connected to the driving member 4 to fix the current positions of the driving member 4 and each fixing member 5;

[0030] The cover plate 7 is arranged on the exposed surface of the carrier plate 1, and the cover plate 7 is detachably connected to the carrier plate 1 through a plurality of fixing screws 8.

[0031] In this embodiment, when the milling cutter blade 3 needs to be replaced, first reverse the two reinforcement members 6 to cancel the fixed state of the driving member 4. Subsequently, only by rotating the driving member 4 in the reverse direction can each fixing member 5 leave the fixing hole 31 on the milling cutter blade 3, cancel the fixing of the milling cutter blade 3, and thus replace the milling cutter blade 3. When the new milling cutter blade 3 needs to be fixed, just reverse the above steps. Through the provided reinforcement member 6, fixing member 5 and driving member 4, the quick disassembly and assembly of the milling cutter blade 3 can be realized. At the same time, compared with the technical solution in the comparative document, the stability of the fixing of the milling cutter blade 3 can be improved, and the milling cutter blade 3 can be prevented from loosening or flying out during use.

[0032] Specifically, refer toFigures 2-4 , the driving member 4 includes a fixing ring 41 disposed in the middle of the bearing plate 1; a bearing 42 sleeved on the outer wall of the fixing ring 41; a rotating ring 43 sleeved on the outer wall of the bearing 42; and a plurality of ratchet teeth 44 disposed on the inner wall of the rotating ring 43.

[0033] Specifically, referring to Figure 2 , the fixing member 5 includes an insertion block 51 slidably disposed in the relative fixing groove 2, and one end of the insertion block 51 penetrates through the fixing hole 31 on the corresponding milling blade 3; two hinge seats 52 respectively disposed on the outer wall of the insertion block 51 and the outer wall of the rotating ring 43; and the two hinge seats 52 are hinged by a connecting rod 53.

[0034] In this embodiment, when the fixing ring 41 rotates, the insertion block 51 can be driven to leave the fixing hole 31 on the milling blade 3 through the cooperation between the two hinge seats 52 and the connecting rod 53, thereby canceling the fixation of the milling blade 3 for replacement. If it is necessary to fix the milling blade 3, only the above steps need to be operated in reverse. By using the method of fixing the milling blade 3 by the insertion block 51 penetrating the fixing hole 31, since the insertion block 51 is a columnar structure and both ends are limited by the fixing groove 2, it can resist the centrifugal force generated by the milling blade 3 during rotation. Compared with the technical solution in the comparative document, it can provide a more stable fixing effect, prevent the milling cutter from being easily loosened, affect the milling effect, and even cause the milling cutter to fly out and cause a safety accident in severe cases.

[0035] Specifically, referring to Figure 4 , the reinforcing member 6 includes a column 61 disposed inside the bearing plate 1 and located in the rotating ring 43; a ratchet block 62 sleeved on the outer wall of the column 61; and a torsion spring 63 disposed between the ratchet block 62 and the column 61, with both ends of the torsion spring 63 connected to the inner wall of the ratchet block 62 and the outer wall of the column 61 respectively.

[0036] In this embodiment, when the blade needs to be replaced, the ratchet block 62 can be first pulled away from the ratchet teeth 44 to cancel the fixation of the fixing ring 41, so that it can be reversed to cancel the fixed state of the milling blade 3. When it is necessary to fix the milling blade 3, the fixing ring 41 rotates counterclockwise. Through the cooperation between the ratchet block 62 and the ratchet teeth 44 and the elastic force provided by the torsion spring 63, the ratchet block 62 can be inserted into the ratchet teeth 44 back and forth to fix the rotating ring 43. Compared with the technical solution in the comparative document, when fixing the milling blade 3, there is no need for cumbersome operation, and only the fixing ring 41 needs to be rotated, thereby simplifying the operation process and improving the operation simplicity and efficiency.

[0037] Although embodiments of the present utility model have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present utility model. The scope of the present utility model is defined by the appended claims and their equivalents.
