[0031] The following further elaborates in detail the detailed implementation manners of the present utility model in conjunction with the accompanying drawings.

[0032] As Figures 1-6 shown, a structure for positioning a cutting tool includes a rotatable rotating shaft 1, and a plurality of cutting tools 2 are arranged on the rotating shaft 1.

[0033] Meanwhile, a clamping member 3 is arranged below the rotating shaft 1, and the clamping member 3 can move along the length direction of the rotating shaft 1. Moreover, the clamping member 3 includes a base 31 and two movable clamping portions 32. Among them, the base 31 is connected to a first driving member 4 for driving the clamping member 3 to move, and a second driving member 33 is arranged between the base 31 and the two clamping portions 32, and the second driving member 33 is used to drive the two clamping portions 32 to move synchronously inward or outward.

[0034] Therefore, during actual use, the clamping member 3 is driven by the first driving member 4 to move to a specified position, and the two clamping portions 32 are driven by the second driving member 33 to move synchronously inward and clamp on both sides of the rotating shaft 1. At this time, moving the cutting tool 2 to one side of the clamping member 3 completes the adjustment of the position of the cutting tool 2. Therefore, by moving the clamping member 3, the position of the cutting tool 2 is pre-positioned, replacing manual measurement, which saves time and effort and is more accurate.

[0035] Among them, the moving structure of the clamping member 3: First, a mounting plate 5 is arranged below the rotating shaft 1, and a lead screw 6 is arranged on the mounting plate 5. A nut 61 is arranged on the lead screw 6. Moreover, a groove is opened at the bottom of the base 31 for the lead screw 6 to pass through, and a mounting portion 34 connected to the nut 61 is arranged in the groove of the base 31. At the same time, one end of the lead screw 6 is connected to a first driving member 4.

[0036] Therefore, in the actual use process, the first driving member 4 drives the lead screw 6 to rotate, thereby driving the nut 61 to move and driving the base 31 to move.

[0037] Secondly, both ends of the lead screw 6 are arranged on the mounting plate 5 by passing through the mounting seats 7. The relevant structure of the first driving member 4 is as follows: First, the first driving member 4 is arranged at the bottom of the mounting plate 5. A first synchronous pulley 42 is sleeved on the driving rod 41 of the first driving member 4. A second synchronous pulley 62 is sleeved on one end of the lead screw 6. The first synchronous pulley 42 and the second synchronous pulley 62 are connected by a belt.

[0038] Therefore, in the actual use process, conduction is realized through the cooperation of the belt and the synchronous pulleys. The first driving member 4 can be a motor.

[0039] At the same time, two slide rails 51 are arranged on both sides of the lead screw 6 on the mounting plate 5, and sliding blocks 35 are arranged at the bottom of the base 31 corresponding to the slide rails 51.

[0040] Therefore, in the actual use process, the movement is guided through the arrangement of the slide rails 51 and the sliding blocks 35 to ensure linear movement.

[0041] As Figure 5 shown, the relevant structure of the base 31 is as follows: First, the base 31 includes two bottom plates 311. Two connecting blocks 312 are arranged at the bottom of the lower bottom plate 311. A sliding block 35 is arranged at the bottom of the connecting block 312. The groove opened at the bottom of the base 31 is between the two connecting blocks 312.

[0042] Moreover, the lower bottom plate 311 is connected to the mounting portion 34. Secondly, a hole is opened in the middle of the mounting portion 34 for the nut 61 to pass through. A connecting plate 611 is arranged at one end of the nut 61. The mounting portion 34 is connected to the connecting plate 611 by screws.

[0043] As Figures 1-6 shown, the relevant structure of the second driving member 33 is as follows: First, the second driving member 33 is a finger cylinder. Two moving blocks 331 that move synchronously are arranged on the second driving member 33. A clamping portion 32 is arranged at the top of the moving block 331.

[0044] Among them, a connecting groove 321 is opened at the bottom of the clamping portion 32. The top of the moving block 331 is located in the connecting groove 321. The clamping portion 32 and the moving block 331 are connected by screws.

[0045] AsFigures 1-6 As shown, the relevant structure of the rotating shaft 1 is as follows: First, support plates 81 and 82 are respectively arranged at both ends of the rotating shaft 1, and a support rod 83 is arranged between the support plates 81 and 82. Moreover, both the support plates 81 and 82 are divided into an upper plate 84 and a lower plate 85, and the end of the rotating shaft 1 is located between the upper plate 84 and the lower plate 85.

[0046] Therefore, during actual use, the installation of the rotating shaft 1 is realized by placing the end of the rotating shaft 1 between the upper plate 84 and the lower plate 85. Specifically, the end of the rotating shaft 1 is the connecting part 12 at both ends of the rotating shaft 1, that is, the connecting part 12 is located between the upper plate 84 and the lower plate 85, and a bearing is sleeved outside the connecting part 12 to prevent the upper plate 84 and the lower plate 85 from being driven to rotate.

[0047] Moreover, corresponding to the above mounting plate 5, the structure of the support plate and the mounting plate 5 is that the mounting plate 5 is arranged between the support plates 81 and 82, and both the support rod 83 and the mounting plate 5 can play a supporting role.

[0048] Secondly, a first gear 11 is arranged at one end of the rotating shaft 1, a second gear 10 is arranged below the first gear 11, and the second gear 10 is connected to a third driving member. The support plate 81 is provided with an opening for the second gear 10 to pass through.

[0049] Therefore, during actual use, the third driving member drives the second gear 10 to rotate, thereby driving the first gear 11 to rotate and further driving the rotating shaft 1 to rotate. Among them, the third driving member can be a motor, and there are other transmission structures between the second gear 10 and the third driving member, and they are not directly connected, such as gears or belt transmission structures.

[0050] As Figures 1-6 shown, it also includes a first side plate 91 and a second side plate 92. The rotating shaft 1 is located between the first side plate 91 and the second side plate 92. Moreover, a roller 94 is arranged between the first side plate 91 and the second side plate 92. A plurality of rollers 94 are respectively located on both sides of the rotating shaft 1 for transporting workpieces, that is, the rollers 94 are used for feeding for slitting and transporting the slit workpieces out.

[0051] At the same time, a cover 93 is arranged outside the first side plate 91, and the cover 93 is used to cover the components arranged on the first side plate 91 to protect these components.

[0052] Moreover, the connection between the side plate and the support plate is made by using a connecting rod 20, that is, the connecting rod 20 passes through the first side plate 91, the support plate 81, the support plate 82 and the second side plate 92 for connection.

[0053] The basic principle, main features and advantages of the present utility model have been shown and described above. Meanwhile, the present utility model is not restricted by the above-mentioned embodiments. Therefore, without departing from the principle and scope of the present utility model, various changes and improvements will occur to the present utility model, and all these changes and improvements fall within the scope of the present utility model claimed.
