Utility model content:
The purpose of this utility model is to overcome the deficiency of above-mentioned prior art, provides a kind of simple in structure, and hobboing cutter dismounting and change is easy, the cutter head structure of the plane wall telephone of weight saving.
The purpose of this utility model is achieved through the following technical solutions:
A kind of cutter head structure that digs wall telephone, comprise rotating disk, described rotating disk comprises inner ring and outer ring, between described inner ring and outer ring, form cavity volume, in described cavity volume, be provided with multiple hobboing cutter groups, each hobboing cutter group is all sleeved on a bearing pin rotationally, the inner ring of described bearing pin autorotation disk is inserted to outer ring, described bearing pin one end is bearing on the outer ring of rotating disk, the described bearing pin other end is cap end, the cap end of described bearing pin is lived by the inner ring backstop of rotating disk, the inner ring inner side of described rotating disk is provided with a retainer, the outer wall of described retainer supports item with the cap end of bearing pin and coordinates, in order to limit moving axially of bearing pin.
Described retainer is fixed by screws on rotating disk.
Between described bearing pin and hobboing cutter group, be set with a cylindrical spring, the outer ring of described cylindrical spring one end and rotating disk is supported, and the inner ring of the other end and rotating disk supports item.
Between the both sides of described hobboing cutter group and the outer ring of rotating disk and inner ring, be respectively equipped with a pad.
The upper center of described rotating disk is fixed with a steel bushing by screw.
Described multiple hobboing cutter groups are uniformly distributed along the circumferencial direction of cavity volume.
Each hobboing cutter group includes three hobboing cutters that are arranged side by side.
Described rotating disk adopts aluminium die casting structure.
The beneficial effects of the utility model are:
First, in the utility model cutter head structure the installation of hobboing cutter group relatively simple, each hobboing cutter group is arranged on respectively on a bearing pin, by a retainer, each bearing pin is carried out to item tightly simultaneously, when dismounting and change hobboing cutter, only retainer need be unloaded, then extract each bearing pin, very convenient.
Secondly, cutterhead main part, rotating disk is aluminium diecasting, lighter than existing iron cutter head structure weight, can alleviate like this weight of machine, alleviates the weight of bearing when operator works, and is conducive to the hand-held of machine.
Accompanying drawing explanation:
Fig. 1 is the cross-sectional schematic of the utility model cutter head structure.
Fig. 2 is the elevational schematic view of the utility model cutter head structure.
Fig. 3 is the schematic perspective view of looking up of the utility model cutter head structure.
The specific embodiment:
Introduce in detail the utility model below in conjunction with the drawings and specific embodiments.
As shown in Figure 1 to Figure 3, a kind of cutter head structure that digs wall telephone described in the utility model, comprises the rotating disk 1 that an aluminium die casting forms, and rotating disk 1 comprises inner ring 11 and outer ring 12, between inner ring 11 and outer ring 12, forms cavity volume 13, is provided with five hobboing cutter groups 2 in cavity volume 13.Each hobboing cutter group 2 is all sleeved on a bearing pin 3 rotationally, the inner ring 11 of bearing pin 3 autorotation disks 1 is inserted to outer ring 12, bearing pin 3 one end are bearing on the outer ring 12 of rotating disk 1, bearing pin 3 other ends are cap end 30, and the cap end 30 of bearing pin 3 is lived by inner ring 11 backstops of rotating disk 1, and inner ring 11 inner sides of rotating disk 1 are provided with a retainer 4, retainer 4 is fixed on rotating disk 1 by screw 5, the outer wall of retainer 4 is supported and is coordinated with the cap end 30 of bearing pin 3, in order to limit moving axially of bearing pin 3, realizes the locking to each bearing pin 3.When dismounting and change hobboing cutter, only need back out screw 5 retainer 4 is unloaded, then extract each bearing pin 3 and can change hobboing cutter, very convenient.
For fear of retainer 4 in locking when each bearing pin 3, there is distortion and extruding hobboing cutter group 2 with outer ring 12 in the inner ring 11 of rotating disk 1, between described bearing pin 3 and hobboing cutter group 2, be set with a cylindrical spring 6, the outer ring 12 of cylindrical spring 6 one end and rotating disk 1 is supported, and the inner ring 11 of the other end and rotating disk 1 is supported; Meanwhile, between the outer ring 12 of the both sides of hobboing cutter group 2 and rotating disk 1 and inner ring 11, be respectively equipped with a pad 7.
The upper center of rotating disk 1 is fixed with a steel bushing 9 by screw 8, in order to coordinate with the rotating shaft of machine, thereby realizes the function of digging wall with movable knife disc rotary work.
