Description

Technical Field

[0001] The utility model relates to the technical field of cutting equipment, in particular to a cutting chuck, a cutting device and a machine tool. Background Art

[0002] Currently, flexible sheet products (such as wovens, non-woven fabrics, paper, leather, synthetic materials, composite materials, etc.) require a large amount of cutting during the production process. Cutting machines are usually used to cut sheet products into specified shapes. The cutting blade is a slender blade with a sharp cutting edge. The cutting edge advances through the sheet along the specified cutting line while the blade reciprocates in a direction roughly perpendicular to the material.

[0003] Traditional cutting machines use a motor to convert rotary motion into an up-and-down reciprocating motion to cut materials. The blade is bolted to the front of the motion mechanism. This makes the blade susceptible to bending and damage during assembly and disassembly, increasing the blade's breakage rate. Furthermore, the blade can't cut along the intended trajectory during the cutting process, further increasing material loss. Utility Model Content

[0026] Please also refer to Figures 1 to 4 Now, the cutting chuck provided in the embodiment of the present utility model is described.

[0027] like Figure 1 and Figure 4 As shown, the cutting chuck of an embodiment of the present invention includes: a clamping block 100; the clamping block 100 is provided with a first clamping arm 110 and a second clamping arm 120, and a mounting groove 130 for clamping the blade 320 is formed between the first clamping arm 110 and the second clamping arm 120; the first clamping arm 110 is provided with a tapered groove 111 on the side away from the second clamping arm 120.

[0028] The mounting groove 130 formed by the cooperation of the first clamping arm 110 and the second clamping arm 120 is used to clamp the blade 320, and the tapered groove 111 is used to allow the external top screw 400 to push against the second clamping arm 120. Therefore, when the cutting chuck of this embodiment is used in a cutting machine, the top screw 400 on the cutting machine can be directly used to align with the tapered groove 111 and screwed in, so that the top screw 400 fixes the chuck on the cutting machine. The top screw 400 can also provide a pressing force to the first clamping arm 110, so that the first clamping arm 110 and the second clamping arm 120 cooperate to clamp the blade 320 in the mounting groove 130, thereby increasing the contact area between the blade 320 and the chuck, making it less likely to bend, and having high installation accuracy. It can also achieve the purpose of clamping the blade 320 and fixing the cutting chuck at the same time with one tightening, making it convenient to disassemble and replace the blade 320. Secondly, the installation accuracy of the cutting chuck and the blade 320 is improved, so that the cutting trajectory of the blade 320 can be better aligned with the preset trajectory, thereby improving the cutting qualification rate and reducing the loss of the sheet material.

[0029] In some embodiments of the present invention, referring to Figure 1 and Figure 4 The central axis of the tapered groove 111 is located in the middle of the first clamping arm 110, so that the pressure applied by the top screw 400 can be aligned with the middle of the mounting groove 130, and the pressure of the top screw 400 can be evenly transferred to the blade 320, so that the cutting chuck can better clamp the blade 320.

[0030] In some embodiments of the present invention, referring to Figure 1 and Figure 4A first clamping surface 112 is provided on the side of the first clamping arm 110 facing the second clamping arm 120. The central axis of the tapered groove 111 is perpendicular to the first clamping surface 112. This allows the pressure applied by the jackscrew 400 to be better transmitted to the blade 320 through the first clamping surface 112, thereby increasing the clamping force between the first clamping arm 110 and the second clamping arm 120, better securing the blade 320 within the mounting groove 130, and ensuring that the blade 320 does not fall out of the mounting groove 130. A second clamping surface 121 is also provided on the side of the second clamping arm 120 facing the first clamping arm 110. The second clamping surface 121 is parallel to the first clamping surface 112, so as to cooperate with the first clamping surface 112 to clamp the flat blade 320.

[0031] In some embodiments of the present invention, referring to Figure 1 and Figure 4 A mounting surface 113 is provided on the side of the first clamping arm 110 facing away from the second clamping arm 120. The mounting surface 113 is perpendicular to the central axis of the tapered groove 111. This allows the pressure of the push screw 400 to be applied directly against the first clamping arm 110 when the push screw 400 is aligned with the tapered groove 111 and tightened. This allows the pressure of the push screw 400 to be more evenly applied to the blade 320, thereby better clamping the blade 320.

[0032] In some embodiments of the present invention, referring to Figure 1 and Figure 4 The first clamping arm 110 and the second clamping arm 120 both extend along the length direction of the clamping block 100 to ensure that the mounting groove 130 also extends along the length direction of the clamping block 100 to better clamp the flat blade 320.

[0033] Reference Figures 2 to 4 , this embodiment also provides a cutting device, which includes: a driving mechanism 200, a cutting mechanism 300 and a cutting chuck and a top screw 400 as described above; the driving mechanism 200 is used to drive the cutting mechanism 300 to reciprocate; the cutting mechanism 300 includes a moving part 310 and a blade 320; the moving part 310 is provided with a chuck mounting hole 311, and the cutting chuck is located in the chuck mounting hole 311; the moving part 310 is provided with a top screw threaded hole 312 at a position corresponding to the tapered groove 111, and the top screw 400 is threadedly connected to the top screw threaded hole 312, and the blade 320 has a clamping section 321 and a cutting section 322, the clamping section 321 is connected to the cutting section 322, the clamping section 321 is arranged in the mounting groove 130, and the cutting section 322 is arranged outside the chuck mounting hole 311, the top screw 400 extends into the tapered groove 111 and presses the first clamping arm 110 toward the second clamping arm 120 to clamp the clamping section 321.

[0034] The driving mechanism 200 may use a driving motor (or a pneumatic driving mechanism) and a crank rocker mechanism to drive the cutting mechanism 300 to reciprocate, thereby achieving the purpose of reciprocating movement of the moving part 310 and the blade 320 along the first direction.

[0035] When installing the blade 320, the cutting chuck can be placed into the chuck mounting hole 311 first, and then the clamping section 321 of the blade 320 can be extended into the mounting groove 130. Finally, the position of the tapered groove 111 and the top screw 400 can be adjusted so that the top screw 400 can apply pressure to the first clamping arm 110 through the tapered groove 111 to achieve the purpose of clamping the cutting chuck and the blade 320.

[0036] Reference Figures 2 to 4 In some embodiments of the present invention, the first direction X is parallel to the length of the clamping block 100 and is the axial direction of the cutting motion. The driving mechanism 200 is used to drive the cutting mechanism 300 to reciprocate along the first direction. The moving portion 310 and the blade 320 are arranged sequentially along the first direction. The chuck mounting hole 311 is located on the side of the moving portion 310 facing the blade 320 and extends along the first direction. That is, the chuck mounting hole 311 is parallel to the first direction, which allows the flat blade 320 to be aligned with the first direction, facilitating cutting.

[0037] Reference Figures 2 to 4 In some embodiments of the present invention, the first clamping arm 110 and the second clamping arm 120 both extend along the first direction, that is, the mounting groove 130 also extends along the first direction, so that the flat blade 320 is positioned through the mounting groove 130 so that the length direction of the blade 320 is parallel to the first direction.

[0038] Reference Figures 2 to 4 In some embodiments of the present invention, the center line Y of the mounting groove 130 and the axis Y of the moving part 310 are located on the same straight line. Figure 4 As shown, after the blade 320 is installed, the central axis of the blade 320 coincides with the axis of the moving part 310, so that the orientation of the blade 320 can be adjusted by rotating the position of the moving part 310.

[0039] It should be noted that the cutting device can be an ultrasonic cutting device, and the moving part 310 is a transducer and a horn, so that the blade 320 can not only reciprocate but also increase the ultrasonic axial vibration, thereby improving the cutting speed and cutting ability of the cutting machine.

[0040] This embodiment also provides a machine tool comprising: a drive device, a mounting post, and a cutting device as described above. The cutting device is mounted on the mounting post. The drive device is configured to drive the cutting device to generate vibrations for cutting and to move along a predetermined path. The cutting device may be an ultrasonic cutting device. The drive device may be a linear drive module or a multi-axis drive module to drive the ultrasonic cutting device to move linearly or spatially. The drive device may also be connected to a transducer to cause the cutting device to generate ultrasonic high-frequency vibrations, thereby enhancing the cutting mechanism's cutting capability. The machine tool can directly utilize the ultrasonic cutting device described above.

[0041] In summary, the cutting chuck, cutting device and machine tool of this embodiment have at least the following beneficial effects. The cutting chuck can be directly screwed into the tapered groove 111 using the top screw 400, so that the top screw 400 fixes the chuck on the cutting machine. The top screw 400 can also provide a clamping force to the first clamping arm 110, so that the first clamping arm 110 and the second clamping arm 120 cooperate to clamp the blade 320 in the mounting groove 130, thereby increasing the contact area between the blade and the chuck, making the blade less likely to bend, and having high installation accuracy. It can also achieve the purpose of clamping the blade 320 and fixing the cutting chuck at the same time with one tightening, making it convenient to disassemble and replace the blade 320. Secondly, the installation accuracy of the cutting chuck and the blade 320 is improved, so that the cutting trajectory of the blade 320 can be better coincided with the preset trajectory, thereby improving the cutting qualification rate and reducing the loss of the sheet material.

[0042] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and replacements can be made without departing from the technical principles of the present invention. These improvements and replacements should also be regarded as the scope of protection of the present invention.
