[0016] Compared with the prior art, the utility model has the following beneficial effects:

[0017] 1) The portable semi-automatic chip cutting device integrates the hand-held portion, the driving source, the auxiliary hand-held transmission component and the positioning jig component. The hand-held portion is a holding part of the whole, which is convenient for the operator to hold and operate; the driving source provides power for chip cutting operation and is installed in the hand-held portion, so that the power source is closely combined with the operating part, thereby reducing the size and weight of the equipment; the auxiliary hand-held transmission component is movably inserted at one end of the hand-held portion, so as to realize power transmission and driving of the cutting shaft; the positioning jig component is fixedly arranged at one end of the auxiliary hand-held transmission component and is used for positioning the workpiece. The integrated design compactly combines each part required for chip cutting, which is convenient for carrying and using in different work sites, and enables the operator to conveniently operate the whole chip cutting process without switching and adjusting between different equipment, thereby improving the convenience and work efficiency of operation.

[0018] 2) The array of positioning plates on the inside of the jig seat in the positioning jig component is movably provided with a spline shaft that penetrates the entire body of the jig seat, which can flexibly adjust the position of the spline shaft according to the shape and size of different workpieces, accurately position and fix the workpiece, ensure that the workpiece does not displace during the cutting process, and improve the accuracy of cutting. At the same time, the unloading block on the side of the jig seat can deform in height under the action of the electric field. This unique design facilitates the unloading of the workpiece after the cutting is completed. By controlling the deformation of the unloading block through the electric field, damage to the workpiece or equipment caused by traditional mechanical unloading methods can be avoided, making the unloading process more efficient, safe and accurate.

[0019] 3) The insertion positioning part and the rectangular through hole inside it that extends outward from one end of the jig seat can insert additional positioning pins or positioning elements to provide more accurate positioning reference for the workpiece, further enhancing the accuracy of positioning.

The deformation layer in the unloading block is composed of a first piezoelectric ceramic block, an insulating layer and a second piezoelectric ceramic block connected from inside to outside. This design takes advantage of the properties of piezoelectric ceramics to achieve precise and controllable deformation, ensuring stable and reliable unloading process and reducing the risk of workpiece damage or equipment failure caused by improper unloading.

[0020] 4) The transmission shafts arranged in a straight line array on the drive connection seat of the auxiliary handheld transmission component can rotate. The ends of adjacent transmission shafts are engaged with the driving source. This transmission structure makes power transmission more uniform and stable, ensuring that the cutting shaft obtains stable driving force. The second spline shaft at one end of the transmission shaft can be easily replaced with different cutting tools to meet different cutting needs. The other end of the transmission shaft can be deformed, which can absorb part of the vibration and reduce the transmission of vibration during cutting, improving the stability and accuracy of cutting. The sheath around the drive connection seat can be movably inserted, and one end is fixedly connected with the positioning jig component. Not only does it protect the internal transmission components, but it also tightly connects all the components together, enhancing the stability of the overall structure.

[0021] 5) The handheld handle fixed on one side of the sheath makes it easy for the operator to hold, making the operation more comfortable and stable. The long strip-shaped holes arranged on the sheath not only ensure the strength of the sheath structure, but also reduce the weight, making it easy for the operator to observe the working state of the internal transmission components. The linear bearing inserted into the drive connection seat reduces the friction between the transmission components, improves the transmission efficiency and accuracy, and ensures the stability of the transmission components under long-term operation, thereby improving the cutting quality and service life of the equipment.

[0022] 6) The driving source is a driving motor and is fixed in the inside of the handheld part through a motor mounting seat. The driving motor is mounted in the handheld part, so that the overall structure is more compact. The motor mounting seat provides a stable mounting base for the driving motor, reduces the vibration and deviation of the driving motor during operation, ensures the stable output power of the driving motor, avoids the safety hazards that may be caused by the exposure of the driving motor, and improves the safety and reliability of the equipment.

[0023] 7) The second long strip-shaped hole arranged in an array on the handheld part, on the one hand, reduces the weight of the handheld part, facilitates carrying and operation; on the other hand, is conducive to heat dissipation of the internal equipment, prevents heat accumulation caused by long-time use, and ensures normal operation of the equipment. The detachable driving source mounting bracket on the inside and the inner recessed U-shaped groove thereon facilitate the installation and maintenance of the driving source. The handle on the top of the handheld part facilitates carrying, and the switch position corresponding to the handle is designed reasonably, facilitating the operation of the operator, making the start and stop operation more convenient and fast, and improving the convenience of operation and the safety of the equipment.

[0024] In summary, through the above structural design and functional characteristics, the portable semi-automatic chip cutting device has many advantages in portability, chip cutting precision, operation convenience, workpiece positioning and unloading, power transmission and equipment safety, and provides an efficient and practical chip cutting solution for the field of on-site maintenance and small-scale machining.
