As the core actuator of cutting equipment, the stability of the blade and the ease of installation have a vital impact on cutting quality, efficiency, and the overall performance of the equipment.

[0003] Traditional blade fixing methods in cutting equipment present numerous problems that urgently need to be addressed. Early fixing methods often used simple bolt tightening or clamping. However, during prolonged cutting operations, the blades are prone to loosening due to vibration, impact, and temperature changes. Once the blade loosens, cutting accuracy drops significantly, the cut surface becomes rough and uneven, making it difficult to guarantee product quality, increasing the defect rate, and raising production costs. Furthermore, the traditional fixing base is cumbersome and complex to install and remove blades, requiring highly skilled and experienced operators and consuming a considerable amount of time. This not only reduces equipment efficiency but also limits production continuity and automation to some extent. In addition, traditional fixing bases lack precise position adjustment mechanisms, making it difficult to quickly and accurately adjust the blade position according to different cutting process requirements, thus failing to meet diverse production needs.

[0025] Example

[0026] Reference Figure 1-4This is an embodiment of the present invention, which provides a cutting device blade holder, comprising:

[0027] The support assembly 100 includes a fastener 101, a support 102 inserted into the side wall of the fastener 101, a bushing 103 fixedly connected in the middle of the support 102, a guide shaft 104 inserted in the middle of the bushing 103, and a fixing plate 105 fixedly connected to the end of the guide shaft 104.

[0028] The blade mounting assembly 200 includes a support plate 201 fixedly connected to the side wall of the fixing plate 105, a slider 202 slidably mounted on the side wall of the support plate 201, a clamping block 203 fixedly connected to the end of the slider 202, and a positioning block 204 adapted to be mounted on the side wall of the support plate 201. The clamping block 203 and the positioning block 204 are used together, and the clamping block 203 is slidably connected to the side wall of the fixing plate 105.

[0029] The fixing component 101 serves as the basic fixing part of the entire support assembly. Its side wall has an interface for inserting the support component 102, and it is fixedly connected to the support component 102 with bolts. This facilitates fixing to the side wall of the equipment, such as the end of a column or connecting rod, for easy integration with the equipment. The bushing 103 is fixed in the middle of the support component 102, providing a precise guide channel for the guide shaft 104. This reduces friction and wear on the guide shaft 104 during movement, ensuring smooth and stable movement. It also provides accurate guidance for the movement of the fixing plate 105, ensuring that the fixing plate 105 can move smoothly in a predetermined direction. The fixing plate 105 is used to connect the blade mounting assembly 200. The support plate 201 is fixedly connected to the side wall of the fixing plate 105 and is the main support structure of the blade mounting assembly. The sliding component 202 is slidably mounted on the side wall of the support plate 201, allowing it to slide smoothly on the support plate 201. Its end is fixedly connected to a clamping block 203, and its sliding motion drives the clamping block 203 to move. The positioning block 204 is used in conjunction with the clamping block 203 to hold the blade. It provides positioning and support for the clamping block 203, ensuring the accuracy and stability of the clamping block 203 during movement and stably holding the blade.

[0030] Specifically, the blade mounting assembly 200 also includes a positioning post 205 fixedly connected to the side wall of the clamping block 203, with the end of the positioning post 205 inserted into the middle of the through hole in the side wall of the positioning block 204.

[0031] The positioning post 205 is fixedly connected to the side wall of the clamping block 203, and its end is inserted into the middle of the through hole in the side wall of the positioning block 204. The positioning post 205 further enhances the connection stability and positioning accuracy between the clamping block 203 and the positioning block 204, preventing the clamping block from shifting during operation.

[0032] Furthermore, the blade mounting assembly 200 also includes a clamping motor 206 fixedly connected to the side wall of the support plate 201, and a gear 207 adapted to be installed at the output end of the clamping motor 206, the side wall of the gear 207 meshing with the rack at the end of the clamping block 203.

[0033] The clamping motor 206 is fixedly connected to the side wall of the support plate 201, serving as the power source for the movement of the clamping block 203. The clamping motor 206 provides precise torque and speed control, driving the clamping block 203 to move via a gear 207 at its output end, thus achieving the clamping and releasing operation of the blade. The gear 207 is fitted onto the output end of the clamping motor 206, and its side wall meshes with the rack at the end of the clamping block 203. When the clamping motor 206 drives the gear 207 to rotate, the rotational motion is converted into linear motion of the clamping block 203 through the meshing transmission of the gear and rack.

[0034] Furthermore, the blade mounting assembly 200 also includes a limiting post 208 mounted on the side wall of the support plate 201, and a guide wheel 209 rotatably mounted on the side wall of the limiting post 208, the guide wheel 209 being located outside the clamping block 203.

[0035] The limiting post 208 is installed on the side wall of the support plate 201 to limit the movement range of the clamping block 203 and prevent it from loosening. The guide wheel 209 is rotatably installed on the side wall of the limiting post 208, located outside the clamping block 203. The guide wheel can reduce the friction of the clamping block 203 during movement and guide the blade to ensure the installation accuracy of the blade.

[0036] Preferably, the support assembly 100 further includes a lead screw 106 rotatably mounted on the side wall of the fixed plate 105, and a ball nut 107 threadedly connected to the middle of the lead screw 106, with the end of the ball nut 107 fixedly connected to the middle side wall of the support member 102.

[0037] The lead screw 106 is rotatably mounted on the side wall of the fixed plate 105 and works in conjunction with the ball nut 107. When the lead screw 106 rotates, it can convert the rotational motion into the linear motion of the ball nut 107, thereby improving the transmission efficiency and accuracy.

[0038] It should be noted that the support assembly 100 also includes a drive motor 108 fixedly connected to the side wall of the fixed plate 105, and the output end of the drive motor 108 is fixedly connected to the lead screw 106.

[0039] The drive motor 108 is fixedly connected to the side wall of the fixed plate 105, and its output end is fixedly connected to the lead screw 106. As a power source, the drive motor 108 can provide precise speed and torque control, and by driving the lead screw 106 to rotate, it realizes the linear movement of the support member 102 along the guide shaft 104.

[0040] Preferably, the fastener 101 and the side wall of the support 102 are fixedly connected by bolts, and the fastener 101 and the support 102 are provided with matching groove structures on their inner sides.

[0041] The fastener 101 and the support 102 are fixedly connected by bolts, which makes it easy to fix to the side wall of the equipment, such as the end of the column, connecting rod and other components, so as to facilitate use with the equipment.

[0042] When the blade needs to be installed or removed, the clamping motor 206 starts, driving the gear 207 at the output end to rotate. The gear 207 meshes with the rack at the end of the clamping block 203, converting the rotational motion into the linear motion of the clamping block 203. Driven by the sliding member 202, the clamping block 203 slides along the side wall of the support plate 201. When the clamping block 203 moves towards the positioning block 204, the positioning pin 205 inserts into the through hole on the side wall of the positioning block 204, enhancing the positioning accuracy of the clamping block 203 and achieving clamping of the blade. When the clamping block 203 moves in the opposite direction, it releases the clamping of the blade. During the movement of the clamping block 203, the limiting pin 208 restricts its range of movement, and the guide wheel 209 reduces the friction between the clamping block 203 and the limiting pin 208, ensuring the smooth movement of the clamping block.

[0043] In summary, the support assembly, through a transmission mechanism using a lead screw and ball nut, enables precise adjustment of the fixed plate position. This allows for accurate blade positioning based on different cutting tasks and workpiece requirements, improving cutting precision and quality. The blade mounting assembly employs a gear and rack transmission and positioning pin system, ensuring stable blade clamping and preventing loosening or displacement during cutting, thus guaranteeing cutting stability and reliability. The bushing provides precise guidance for the guide shaft, while the design of the sliding parts and guide wheels ensures smooth movement of the clamping block, reducing friction and wear between components and improving equipment lifespan and work efficiency. The clamping motor drives the movement of the clamping block, enabling quick blade installation and removal, facilitating blade replacement and maintenance by operators and improving work efficiency. The fixing and support components are connected by bolts and feature a grooved structure, enhancing the stability of the entire support assembly; the limit pins ensure the safety and accuracy of the clamping block movement, improving the overall reliability of the equipment.
