Description

Technical Field

[0002] In the field of mandrel machining, cutting is a key process, and its processing quality and equipment stability directly affect production efficiency and product yield. As the manufacturing industry continues to increase its requirements for mandrel precision and production automation, the problem of debris generated during the cutting process has gradually become one of the bottlenecks restricting the development of the industry. Traditional mandrel cutting devices often neglect the chip removal process or use simple cleaning methods, leading to numerous problems. Some devices rely on manual cleaning at regular intervals, which is not only inefficient, but also results in chips easily remaining on the work platform surface during processing. When a new mandrel is placed, the residual chips can cause workpiece positioning deviations, thereby affecting cutting accuracy and causing quality problems such as out-of-tolerance cutting dimensions and unqualified surface roughness. Therefore, these problems need to be solved. Utility Model Content

A second motor is installed on one side of the processing box 1, and a second lead screw for driving the first moving block 8 to slide is coaxially fixed to the output end of the second motor.

Slide grooves are provided on both sides of the first moving block 8, and the second moving block 11 slides in the slide grooves. A fixed block is provided on one side of the second moving block 11. A third motor is installed on the top side of the first moving block 8, and a first lead screw 10 is coaxially fixed to the output end of the third motor. The fixed block is threadedly connected to the lead screw. The first lead screw 10 facilitates precise control of the lifting distance of the second moving block 11, thereby accurately adjusting the height of the cutting blade 9 to adapt to the processing of mandrels with different diameters or cutting depths. The cutting component includes A stop block is mounted on the placement platform 4. Multiple threaded rods for height adjustment are screwed onto the stop block. A cutting blade 9 is fixedly attached to the bottom middle section of the stop block. A placement groove for the mandrel is provided on the top of the placement platform 4. The cutting components facilitate efficient and precise cutting with their sharp cutting edges and stable mounting structure, ensuring the processing quality and surface finish of the mandrel. A drive shaft is rotatably mounted inside the mounting block 2. The output end of the first motor is coaxially fixed to the drive shaft. A drive gear 13 is fixedly attached to the drive shaft, and a matching gear is fixedly attached to the driven shaft 12. The drive shaft 13 is equipped with a driven shaft 12 on one side of the drive shaft. The drive gear 13 meshes with the mating gear.

A locking block 6 is provided on one side of the support plate 15. The locking block 6 has a locking groove. A brush 14 is engaged with the locking block 6 through the locking groove. The brush 14 helps to keep the working platform clean, reduce the interference of debris on the cutting accuracy, and reduce the risk of equipment failure caused by debris entering.

[0016] Working Principle: In using this utility model, firstly, each electrical component in this application is connected to the power supply. Then, the mandrel to be processed is placed in the three-jaw chuck 3. The three-jaw chuck 3 is activated, and the three jaws retract synchronously, securing the mandrel firmly with a uniform and powerful clamping force. The three-jaw chuck 3 is mounted on the mounting block 2 to ensure the mandrel maintains a stable posture during cutting. Then, the placement groove on the top of the placement table 4 provides a positioning reference for the mandrel. The operator aligns one end of the mandrel with the placement groove to determine the starting position for cutting. Simultaneously, by rotating the threaded rod on the abutment block, the vertical height of the cutting blade 9 can be adjusted to precisely align it with the part of the mandrel to be cut, adapting to different diameter or cutting depth requirements. Then, the cutting component is moved and adjusted laterally. The movement control mechanism works as follows: After the second motor starts, it drives the coaxially connected second lead screw to rotate. Since the bottom of the push plate 7 is threadedly connected to the second lead screw, and the first moving block 8 is fixed by the push plate 7, the rotation of the second lead screw drives the push plate 7 to move laterally along the slide rail. This, in turn, drives the first moving block 8 and the cutting components mounted on it to move as a whole, thus adjusting the horizontal position of the cutting blade 9 to match the cutting requirements of different mandrel lengths. Simultaneously, vertical height adjustment is achieved. When the third motor is running, it drives the first lead screw 10 to rotate. The second moving block 11 is threadedly connected to the first lead screw 10 through a fixed block on one side and can slide up and down in the grooves on both sides of the first moving block 8. As the first lead screw 10 rotates, the second moving block 11 rises and falls along the grooves, thereby achieving precise vertical movement. The vertical height of the cutting blade 9 is precisely adjusted to ensure it can accurately cut into the mandrel to the predetermined depth. Then, after the first motor starts, its output drives the drive shaft to rotate. The drive gear 13, fixed to the drive shaft, rotates accordingly. The drive gear 13 meshes with the mating gear on the driven shaft 12, transmitting power to the driven shaft 12, thus achieving power distribution and speed regulation. This gear transmission system ensures smooth and efficient power transmission to the three-jaw chuck 3, driving the mandrel to rotate at high speed. When the mandrel rotates at high speed, the cutting blade 9, under the coordinated control of the first moving block 8 and the second moving block 11, moves to the predetermined cutting position. The cutting blade 9, with its sharp edge, contacts the surface of the mandrel and cuts it according to the required dimensions through relative motion. The mandrel is cut to a specific size or shape. During the cutting process, the mounting block 2 is connected to the moving parts through the bottom support frame to ensure stability during cutting and avoid a decrease in cutting accuracy due to vibration. Finally, the waste material or finished mandrel produced by cutting falls directly onto the drop plate 5 placed on the support plate 15, realizing the centralized collection of waste material and preventing the processing material from scattering and affecting the working environment and equipment operation. The clamping block 6 on one side of the support plate 15 fixes the brush 14 through the slot. During the cutting process or after processing, the brush 14 can automatically clean the residual debris on the surface of the support plate 15 and the drop plate 5, keep the working platform clean, reduce the interference of debris on subsequent processing, and reduce the risk of equipment failure caused by debris entering. The use of the mandrel processing cutting device ends here.
