[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.

[0027] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, and connecting should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.

[0028] Please also refer to Figures 1 to 5 Now, the clamping member provided in the embodiment of the present utility model is described.

[0029] like Figure 1 and Figure 2 As shown, a clamping member of an embodiment of the present invention includes: a clamping section 100; the clamping section 100 has an open end 110; the clamping section 100 is provided with a clamping hole 120, the extension direction of the clamping hole 120 is parallel to the length direction of the clamping section 100, and the clamping hole 120 extends to the open end 110; the clamping section 100 is provided with a slit 130 passing through the hole wall of the clamping hole 120; the number of the slits 130 is at least two; the extension direction of the slit 130 is parallel to the length direction of the clamping section 100, and the slit 130 extends to the open end 110; the clamping section 100 is provided with an external thread 140 at a position corresponding to the outside of the clamping hole 120.

[0030] At least two slits 130 can enable the clamping section 100 of the clamping member 10 to form at least two clamping arms. An external thread 140 is provided at the outer position of the clamping hole 120. When the clamping member 10 is connected with the internal thread 412 or the internal thread of the threaded hole through the external thread 140, the internal thread 412 or the internal thread of the threaded hole can be used to narrow the slit 130 so that at least two clamping arms clamp the object in the clamping hole 120 to achieve the purpose of clamping and tightening.

[0031] Reference Figure 5 When the clamping member 10 of this embodiment is applied to a cutting machine, an internal thread 412 or a threaded hole with an internal thread can be provided in the motion mechanism of the cutting machine, and then the clamping member 10 is sleeved on the outside of the reciprocating drive rod driven by the motor through the clamping hole 120. Finally, the clamping member 10 is screwed in, and the external thread 140 of the clamping member 10 is matched with the internal thread 412 or the internal thread of the threaded hole. The reciprocating drive rod driven by the motor can be connected to the motion mechanism for convenient connection.

[0032] Compared with the prior art, the use of the clamping member 10 of this embodiment to connect the reciprocating drive rod driven by the motor and the motion mechanism not only saves the steps of connecting multiple bolts and connecting parts, saves connecting parts and multiple bolts, makes the connection between the motion mechanism and the reciprocating drive rod simpler, improves installation efficiency, but also reduces the weight of the motion mechanism and saves energy consumption.

[0033] In some embodiments of the present invention, referring to Figure 1 and Figure 2 The slits 130 are evenly distributed around the axis of the clamping hole 120. This ensures that the clamping arms formed by the slits 130 on the clamping section 100 are of uniform size, resulting in a more uniform clamping force, reduced stress concentration, and a more secure clamping. Based on the above, there are two slits 130. That is, the two slits 130 are symmetrically positioned, forming two clamping arms on the clamping section 100. These two clamping arms clamp the object, ensuring the connection strength of the clamping arms and preventing the clamping member 10 from easily breaking.

[0034] In some embodiments of the present invention, referring to Figure 1 and Figure 2 The wall of the clamping hole 120 is provided with a plurality of clamping grooves 150. The clamping grooves 150 are recessed radially along the clamping member 10, with a raised clamping portion formed between adjacent clamping grooves 150. The multiple clamping portions can increase the clamping force of the clamping hole 120 on the clamped object, thereby better clamping the object and preventing the reciprocating drive rod from loosening from the clamping member 10. Furthermore, the plurality of clamping grooves 150 are evenly spaced along the extending direction of the clamping hole 120. This allows for a more uniform distribution of the clamping force of the clamping member 10 on the clamped object, avoids stress concentration in one spot, and provides a more stable connection.

[0035] In some embodiments of the present invention, referring to Figure 1 and Figure 2 The clamping hole 120 is flared, with the diameter of the clamping hole 120 toward the open end 110 being larger than the diameter of the clamping hole 120 away from the open end 110. That is, the diameter of the clamping hole 120 gradually decreases from the open end 110 toward the end away from the open end 110, thereby better allowing the hole wall of the clamping hole 120 to contact the clamped object, thereby increasing the clamping force and ensuring a secure connection between the clamped object and the clamping member 10.

[0036] In some embodiments of the present invention, referring to Figure 1 and Figure 2The clamping member 10 further includes a mounting section 200 connected to the end of the clamping member 100 facing away from the outlet end 110. The mounting section 200 is provided with an assembly hole 210 extending parallel to the length of the clamping member 10 and having a diameter smaller than the diameter of the clamping hole. The assembly hole 210 facilitates the use of an installation tool to rotate the clamping member 10, thereby screwing the clamping member 10 into the internal thread 412 or threaded hole. The assembly hole 210 can be a hexagonal hole, a square hole, or a cross hole, so that the corresponding installation tool can screw the clamping member 10.

[0037] Reference Figures 3 to 5 The present invention also provides a cutting device, which includes: a driving mechanism 300, a cutting mechanism 400 and the above-mentioned clamping member 10; the cutting mechanism 400 includes a moving part 410 and a blade 420; the cutting device has a first direction X; the first direction X is the axial direction of the cutting movement; Figure 3 As shown; the driving mechanism 300 is used to drive the cutting mechanism 400 to reciprocate along the first direction, and the moving part 410 and the blade 420 are arranged in sequence along the first direction; the driving mechanism 300 is connected to the moving part 410 through the pull rod 500 and the clamping member 10, and the driving mechanism 300 is used to drive the pull rod 500, the moving part 410, and the blade 420 to reciprocate along the first direction; the length direction of the clamping section 100 is parallel to the first direction; the driving mechanism 300 can use a driving motor and a crank rocker mechanism to drive the pull rod 500 to move back and forth, so as to achieve the purpose of reciprocating movement of the pull rod 500, the moving part 410, and the blade 420 along the first direction.

[0038] The moving portion 410 is provided with a first mounting hole 411 on the side facing the pull rod 500, the length of which is parallel to the first direction. The inner wall of the first mounting hole 411 has an internal thread 412. The internal thread 412 cooperates with the external thread 140 of the clamping member 10, and the clamping hole 120 is used to clamp the pull rod 500. In other words, the corresponding internal thread 412 is provided on the moving portion 410, so that the driving mechanism 300 is connected to the moving portion 410 via the pull rod 500 and the clamping member 10 to drive the blade 420 of the cutting mechanism 400 to reciprocate in the first direction. Compared with the prior art, the use of the clamping member 10 of this embodiment to connect the pull rod 500 and the moving portion 410 not only eliminates the need for multiple bolts and connectors, eliminating connectors and multiple bolts, making the connection between the moving mechanism and the reciprocating drive rod simpler and improving installation efficiency, but also reduces the weight of the moving mechanism and saves energy.

[0039] It should be noted that the cutting device can be an ultrasonic cutting device, and the moving part 410 is a transducer and a horn, so that the blade 420 can not only reciprocate but also increase the ultrasonic axial vibration, thereby improving the cutting speed and cutting ability of the cutting machine.

[0040] In some embodiments of the present invention, referring to Figures 3 to 5 The end of the moving portion 410 facing away from the pull rod 500 is provided with a second mounting hole 413 that communicates with the first mounting hole 411. The length of the second mounting hole 413 is parallel to the first direction, and the maximum outer diameter of the clamping member 10 is smaller than the minimum inner diameter of the second mounting hole 413. In other words, the clamping member 10 can be extended through the second mounting hole 413 to the internal thread 412 to clamp the pull rod 500. The clamping member 10 can then be extended into the assembly hole 210 using an installation tool and screwed into the internal thread 412 to facilitate the connection between the pull rod 500 and the moving portion 410.

[0041] 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, and the drive device may be a linear drive module or a multi-axis drive module to drive the ultrasonic cutting device for linear or spatial movement. 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.

[0042] In summary, when the clamp 10 is used in a cutting machine, the clamp 10 is screwed into the internal thread 412 or threaded hole of the cutting machine, and the reciprocating drive rod driven by the motor can be connected to the motion mechanism for easy connection. Compared with the prior art, the clamp 10 of this embodiment is used to connect the pull rod 500 and the motion part 410, which not only saves the steps of connecting multiple bolts and connecting parts, saves connecting parts and multiple bolts, making the connection between the motion mechanism and the reciprocating drive rod simpler, improving installation efficiency, but also reduces the weight of the motion mechanism and saves energy. Similarly, a machine tool with the above-mentioned cutting device can also save the steps of connecting multiple bolts and connecting parts when in use, improves installation efficiency, and reduces the weight of the motion mechanism and saves energy.

[0043] 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.
