[0023] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.
[0024] Please see Figure 1-3As shown, a horseshoe-shaped rotary cutting tool assembly includes a housing 1, a transmission mechanism 2 for transmitting power is provided inside the housing 1, and an installation mechanism 3 is provided on the top of the housing 1. The installation mechanism 3 includes a limiting plate 304 and a bolt 306, both of which are installed on the top of the housing 1. The housing 1 serves as the basic load-bearing structure of the entire blade assembly. Its interior provides a closed and stable mounting space for the transmission mechanism 2, effectively isolating it from external dust, impurities, and cutting debris, preventing wear or jamming of transmission components. Simultaneously, it provides a precise assembly reference for the mounting mechanism 3 above, ensuring the coaxiality of the transmission mechanism 2 and the mounting mechanism 3, and guaranteeing the synchronization of power transmission and cutting actions. The core function of the transmission mechanism 2 is to receive power from an external power source, such as a motor, and stably transmit it to the mounting mechanism 3. The limiting plate 304 and bolt 306 in the mounting mechanism 3 cooperate with each other. The limiting plate 304 provides lateral positioning for the blade 302, preventing horizontal displacement during high-speed rotational cutting. The bolt 306 provides longitudinal clamping force through a threaded connection, firmly fixing the blade 302 within the blade holder 301. Together, they provide structural protection for the stable operation of the blade 302, ultimately achieving the basic function of horseshoe-shaped cutting. An input shaft 201 is rotatably connected to the lower surface of the housing 1, and a pulley 202 is rotatably connected to the bottom of the inner wall of the housing 1. The pulley 202 is fixedly connected to the input shaft 201. One end of the input shaft 201 is connected to an external power source, and the other end is fixedly connected to a pulley 202 at the bottom of the inner wall of the housing 1. Its working principle is to directly transmit the rotational power of the external power source to the pulley 202, serving as the power input for the entire transmission system. The pulley 202 rotates synchronously with the input shaft 201, receiving the power transmitted by the input shaft 201 and engaging with the synchronous belt 203 through its outer teeth, providing a suitable transmission structure for subsequent power transmission. Its function is to realize the transition of power from the input shaft 201 to the synchronous belt 203. Simultaneously, the pulley 202's rotatable connection to the bottom of the inner wall of the housing 1 ensures lower energy loss during power transmission and guarantees power transmission efficiency. There are two pulleys 202; the outer surface of one pulley 202 is engaged with the synchronous belt 203, and one end of the other pulley 202 is fixedly mounted with a rotating shaft 204.Two pulleys 202 are connected by a synchronous belt 203 meshing on their outer surfaces to form a transmission mechanism. The working principle is as follows: when the pulley 202 fixed to the input shaft 201 rotates under power, the friction of the synchronous belt 203 drives the other pulley 202 to rotate synchronously. The toothed structure of the synchronous belt 203 prevents slippage during transmission, ensuring that the two pulleys 202 rotate at the same speed. The rotating shaft 204, fixedly connected to the other pulley 202, rotates synchronously with the pulley 202, transmitting the power received by the pulley 202 upwards to the output shaft 205. Its function is to achieve longitudinal power transmission from the lower part of the housing 1 to the upper part. Simultaneously, the cooperation structure of the double pulleys 202 and the synchronous belt 203 effectively buffers external power fluctuations, reduces speed deviations during power transmission, and provides a uniform power foundation for the subsequent stable cutting by the blade 302. The other end of the rotating shaft 204 is rotatably connected to the top of the inner wall of the housing 1. The output shaft 205 is rotatably connected to the upper surface of the housing 1, and the output shaft 205 is fixedly connected to the rotating shaft 204. The other end of the rotating shaft 204 is rotatably connected to the top of the inner wall of the housing 1. The coaxiality of its rotation is ensured by the rotational support at both ends, preventing the power transmission from being offset due to shaft shaking. One end of the output shaft 205 is fixedly connected to the rotating shaft 204, and the other end extends out of the upper surface of the housing 1 and is connected to the tool holder 301. Its working principle is that the rotating shaft 204 transmits power to the output shaft 205, so that the output shaft 205 rotates synchronously with the rotating shaft 204, thereby driving the tool holder 301 and the blade 302 to rotate at high speed. The function of this structure is to realize the final transmission of power from the transmission mechanism 2 to the cutting execution component. The fixed connection between the rotating shaft 204 and the output shaft 205 can ensure power transmission without loss. At the same time, the output shaft 205 is rotatably connected to the upper surface of the housing 1, which further enhances the stability of the shaft rotation and prevents the blade 302 from having an uneven cutting surface due to shaft shaking during cutting.
[0025] Please see Figure 4-6As shown, a tool holder 301 is fixedly installed at one end of the output shaft 205, a blade 302 is slidably connected to the inner wall surface of the tool holder 301, a pressure block 303 is slidably connected to the inner wall surface of the tool holder 301, and a limiting plate 304 is fixedly connected to one end of the pressure block 303. The output shaft 205 is fixed to the tool holder 301 and rotates synchronously with it. The inner wall surface of the tool holder 301 provides a mounting slot for the blade 302. The blade 302 can slide along the slot to be installed and removed. Its working principle is that when the tool holder 301 rotates with the output shaft 205, it drives the blade 302 to rotate at high speed, and uses the cutting edge of the blade 302 to perform contour cutting of the horseshoe. The pressure block 303 is slidably connected to the inner wall surface of the tool holder 301 and can slide up and down along the inner wall. Its function is to use its own weight and the clamping force of the bolt 306 to tightly fit the blade 302 against the inner wall of the tool holder 301, preventing the blade 302 from detaching from the tool holder 301 due to centrifugal force when rotating at high speed. The limiting plate 304 fixed to one end of the pressure block 303 is in contact with the side of the blade 302, restricting the lateral displacement of the blade 302 in the tool holder 301, ensuring the accurate cutting position of the blade 302, and avoiding the deviation of the horseshoe cutting size due to the offset of the blade 302. A sleeve 305 is fixedly installed at the other end of the pressure block 303. The sleeve 305 is sleeved on the surface of the knife holder 301. One end of the sleeve 305 has an installation hole that penetrates the pressure block 303. The sleeve 305, fixed at the other end of the pressure block 303, is fitted onto the surface of the tool holder 301. Its working principle is that the sleeve 305 can slide along the surface of the tool holder 301, causing the pressure block 303 to move synchronously, facilitating the adjustment of the pressure block 303's position during the installation and removal of the blade 302. The mounting hole at one end of the sleeve 305 penetrates the pressure block 303, providing an installation channel for the bolt 306. Its function is twofold: firstly, the sleeve structure of the sleeve 305 enhances the connection stability between the pressure block 303 and the tool holder 301, preventing the pressure block 303 from tilting when the blade 302 rotates; secondly, the coaxial design of the mounting hole ensures that the bolt 306 is perpendicular to the inner wall of the tool holder 301 during installation, preventing uneven clamping force due to bolt tilting, thus ensuring uniform clamping force of the pressure block 303 on the blade 302 and preventing excessive localized stress on the blade 302, which could lead to damage or loosening and displacement. A bolt 306 is threaded on the inner wall surface of the mounting hole. The bolt 306 passes through the mounting hole and is threaded to the bottom of the inner wall of the tool holder 301. A washer 307 is fitted on the surface of the bolt 306.Bolt 306 is threaded to the inner wall of the mounting hole and the bottom of the inner wall of the tool holder 301. Its working principle is that by tightening bolt 306, the self-locking characteristic of the thread generates axial clamping force, pressing the sleeve 305 and pressure block 303 downwards, making the pressure block 303 tightly fit against the blade 302, thus fixing the blade 302. A washer 307, fitted onto the surface of bolt 306, is located between the head of bolt 306 and sleeve 305. Its function is twofold: firstly, to increase the contact area between the head of bolt 306 and sleeve 305, preventing damage to the surface of sleeve 305 due to excessive local pressure when tightening bolt 306; secondly, the elasticity of washer 307 compensates for the gap in the threaded connection, preventing bolt 306 from loosening under long-term vibration, ensuring the long-term stability of the blade 302. A spring 308 is fixedly installed at one end of washer 307, and multiple washers 307 are used. Another washer 307 is fixedly connected to the other end of spring 308. Two washers 307 are fixed to both ends of the spring 308 to form a buffer structure, which is sleeved on the surface of the bolt 306. The working principle is that when the bolt 306 is tightened, the spring 308 is compressed and contracted by the two washers 307, generating an elastic reaction force. This reaction force continues to act between the washers 307 and the sleeve 305, further enhancing the anti-loosening effect of the bolt 306. During the cutting process, when the blade 302 contacts the horseshoe and generates an impact force, the spring 308 can absorb part of the impact force through its own elastic deformation, preventing the impact force from being directly transmitted to the tool holder 301 and the output shaft 205. Its function is to achieve both active anti-loosening, preventing the bolt 306 from loosening due to vibration, and passive buffering, reducing the wear of the cutting impact force on the transmission and cutting components, extending the overall service life of the tool set, and preventing the blade 302 from chipping due to the impact force, thus ensuring the cutting quality.
[0026] Working Principle: In use, first place the blade 302 into the tool holder 301, then place the pressure block 303 along with the sleeve 305 onto the surface of the tool holder 301, so that the limiting plate 304 fits against the side of the blade 302 for positioning. Next, pass the bolt 306 through the mounting holes on the sleeve 305 and the pressure block 303, and thread it onto the bottom of the inner wall of the tool holder 301. During the tightening of the bolt 306, the pressure block 303 presses against the blade 302, while the spring 308 and washer 307 on the bolt 306 are compressed, forming a buffer and accumulating force. Power is transmitted through the input shaft 201 to the pulley 202 fixedly connected to it. This pulley 202 drives another pulley 202 to rotate synchronously via the synchronous belt 203, thereby causing the rotating shaft 204 to rotate accordingly. The rotating shaft 204 transmits power to the output shaft 205, which drives the tool holder 301 and the blade 302 to rotate at high speed, achieving horseshoe-shaped cutting. During the cutting process, the elasticity of spring 308 absorbs the impact force, preventing damage to the blade 302 and the blade holder 301 due to rigid collision. At the same time, the timing belt 203 ensures the stability of the transmission and guarantees cutting accuracy. If the blade 302 needs to be replaced, simply loosen bolt 306 and remove pressure block 303 for quick replacement. The operation is convenient and efficient.
