Generally, the knife box 140 may be secured to the outer disk 120 by bolting. As shown in fig. 5, the knife box 140 is provided with a receiving cavity 141 extending along the radial direction of the outer disc 120, a first end (an end close to the center of the outer disc 120) of the receiving cavity 141 is provided with a mounting through hole 142, a second end (an end far from the center of the outer disc 120) of the receiving cavity 141 is provided with a mounting threaded hole 143, and the specific structure of the receiving cavity 141 needs to be matched with the scraper 130, the knife bar 150 and the adjusting screw 180 to complete the mounting and fixing of the scraper 130, the knife bar 150 and the adjusting screw 180.

It should be noted that the knife box 140 can be manufactured by dividing into an upper part and a lower part, for example, by taking the central plane of the accommodating cavity 141 as a boundary, the two parts can be connected by a bolt, so that the knife bar 150, the slider 160, the spring 170 and the adjusting screw 180 can be conveniently installed.

As shown in fig. 5, 6 and 7, the cutting edge of the scraper 130 extends along the axial direction of the outer disc 120, that is, the cutting edge of the scraper 130 extends along the axial direction of the pipe or the bar, so as to cut the pipe or the bar.

As shown in fig. 8 and 9, the knife bar 150 is slidably connected in the mounting through hole 142 and extends into the accommodating cavity 141, and the knife bar 150 is connected to an end of the scraper 130 away from the center of the outer disc 120, i.e., the knife bar 150 and the scraper 130 form an integral body, and both slide together along the length direction of the accommodating cavity 141 (i.e., the radial direction of the outer disc 120) relative to the knife box 140.

As shown in fig. 5, 10 and 11, the slider 160 is slidably connected in the accommodating cavity 141, and the slider 160 is connected to an end of the knife bar 150 away from the scraper 130. The slider 160 is provided with a hole structure connected with the cutter bar 150 and the adjusting screw 180. The slider 160 and the tool bar 150 can be connected by adhesion.

As shown in fig. 5, the spring 170 is sleeved on the knife bar 150, one end of the spring 170 abuts against the sidewall of the first end of the accommodating cavity 141, and the other end of the spring 170 abuts against the slider 160, that is, the spring 170 is sleeved on the portion of the knife bar 150 located in the accommodating cavity 141.

The adjusting screw 180 is screwed to the second end of the accommodating cavity 141 and abuts against the slider 160. The front end of the adjusting screw 180 may be provided with a small protruding shaft that cooperates with the hole structure of the slider 160 for positioning and installation.

When the adjustment screw 180 approaches the center of the outer disc 120, the adjustment screw 180 moves against the slider 160, and the slider 160 presses the spring 170, bringing the knife bar 150 and the scraper 130 together close to the center of the outer disc 120, i.e., achieving a change in the feed and cut of the scraper 130.

When the adjusting screw 180 is far away from the center of the outer disc 120, the adjusting screw 180 tends to leave the sliding block 160, but the sliding block 160 is kept in abutment with the adjusting screw 180 under the resilience of the spring 170, so as to drive the knife bar 150 and the scraper 130 to be far away from the center of the outer disc 120, i.e. to realize the knife retracting of the scraper 130.

In some embodiments, as shown in fig. 5 and 8, the mounting through hole 142 is a square hole, the knife bar 150 includes a first circular plate 151 and a square shaft 152, and the square shaft 152 is slidably connected in the mounting through hole 142, so that the whole knife bar 150 does not rotate, and the scraper 130 is not skewed. The first circular plate 151 is connected with the scraper 130, and the first circular plate 151 and the scraper 130 can be connected through bonding, bolt connection and the like, for example, the first circular plate 151 is provided with a threaded hole, the scraper 130 is provided with a through hole, and the first circular plate 151 and the scraper 130 are connected through a bolt, so that the installation is convenient. In this configuration, the end of the square shaft 152 may be formed in a cylindrical configuration to facilitate engagement with the bore structure of the slider 160.

In some embodiments, as shown in fig. 5, the cutter head assembly 100 further comprises a plurality of stop collars 190, the length of the plurality of stop collars 190 is sequentially varied in equal increments, only 1 stop collar 190 is shown, and only 1 stop collar 190 is engaged with the adjusting screw 180 at a time. One end of the adjusting screw 180, which is far away from the center of the outer disc 120, is provided with a second circular plate 181, one of the limiting sleeves 190 is sleeved on the adjusting screw 180, the first end of the limiting sleeve 190 is abutted against the side wall of the knife box 140, and the second end of the limiting sleeve 190 is abutted against the second circular plate 181. Thus, the amount of advance of the adjustment screw 180 (the amount of feed of the scraper 130) is limited by the stopper bushing 190, and the amount of feed of the scraper 130 can be accurately changed by replacing a different stopper bushing 190. Compared with a structure which only depends on a thread screwing mode to change the feed amount, the structure can avoid the influence of the gap between the threads and ensure the accuracy of the feed amount. In addition, the limiting sleeve 190 can also be manufactured into a semi-cylindrical structure, so that the adjusting screw 180 does not need to be screwed off and is directly put on when the limiting sleeve 190 is replaced.

In some embodiments, the length of the plurality of position-limiting sleeves 190 is changed by 0.1mm, that is, the difference between two adjacent position-limiting sleeves 190 in the length arrangement is 0.1mm. Therefore, the change amount of the feed amount can be accurately 0.1mm, and the adjustment precision is improved.

When the rotary blade device is used, the following steps can be performed, taking bar cutting as an example:

s1: the bar is inserted into the positioning cylinder 200 from the material through hole 111 and the three-jaw chuck is adjusted to grip the bar. This allows the rod to be coaxial with the positioning cylinder 200 and fixed.

S2: the adjusting screw 180 is unscrewed, the limiting sleeve 190 is sleeved on the adjusting screw 180, and then the adjusting screw 180 is screwed into the mounting threaded hole 143, so that the limiting sleeve 190 abuts against the side wall of the cutter box 140 to cut the bar.

It should be noted that, when the position limiting sleeve 190 is sleeved for the first time, the micrometer can be used for measuring the existing size of the bar, the difference value between the existing size and the standard size is calculated, and then the position limiting sleeve 190 with a proper length is selected, so that the position limiting sleeve 190 on the first time sleeve can cut the bar or the scraper 130 basically abuts against the bar, and thus the adjustment time can be saved. If the longest stop collar 190 is sleeved directly for the first time, the scraper 130 may be far away from the bar, the bar may not be cut, and the adjustment time is long.

S3: and measuring the size after cutting to see whether the requirements are met. If the requirements are met, the adjusting screw rod 180 is unscrewed to realize tool withdrawal, the three-jaw chuck is loosened, and the bar is taken down. If the size does not meet the requirement, the step S2 is repeated, the limiting sleeve 190 with a shorter length is replaced, and cutting is carried out again until the size after cutting meets the requirement.

Finally, it should be noted that the above embodiments are only used for illustrating the technical solutions of the present application, and not for limiting the same; although the present application has been described in detail with reference to the foregoing embodiments, it should be understood by those skilled in the art; the technical solutions described in the foregoing embodiments may still be modified, or some or all of the technical features may be equivalently replaced; and the modifications or the substitutions do not make the essence of the corresponding technical solutions depart from the scope of the technical solutions of the embodiments of the present application.
