Description

Technical Field

[0001] This utility model relates to the field of CNC vibrating knife cutting machines, and in particular to a CNC vibrating knife cutting machine with adjustable blade distance. Background Technology

[0002] A CNC vibrating knife cutting machine is an automated processing equipment that uses digital program control as its core to precisely cut flexible, semi-flexible, and some medium- and low-density materials using a high-speed vibrating knife.

[0003] Existing CNC vibrating knife cutting machines mainly adjust the blade distance by controlling the Z-axis movement through the CNC system. The core process consists of two steps: parameter setting and precise adjustment. First, enter the blade depth or related parameter interface on the equipment operation interface, select the corresponding blade number and set the fine adjustment step size. Then, drive the blade head to move using the directional keys. Using the table or material surface as a reference, adjust the blade tip to just contact the table or the required depth, and then confirm and save.

[0004] Currently, multi-head cutting machines require each vibrating head to be equipped with a separate servo motor, gear transmission, and other drive components to achieve angle adjustment. This not only doubles the manufacturing cost of the equipment but also increases the complexity of equipment assembly and the difficulty of later maintenance due to the large number of transmission components. To address these issues, a CNC vibrating knife cutting machine with adjustable head distance is proposed. Summary of the Invention

[0005] To overcome the above shortcomings, this utility model provides a CNC vibratory knife cutting machine with adjustable blade head distance, aiming to solve the problem of high manufacturing cost caused by the need for independent drive components to adjust the distance of multiple sets of vibratory blade heads in the prior art.

[0006] To achieve the above objectives, this utility model adopts the following technical solution: a CNC vibrating knife cutting machine with adjustable blade distance, comprising a cutting table, an adjustment mechanism and a switching mechanism on the top of the cutting table, the adjustment mechanism comprising a translation frame, a support block fixedly connected to the top of the translation frame, a rotating block rotatably connected to the outer wall of the support block, a support frame fixedly connected to the outer wall of the rotating block, a lifting block slidably connected to the inner wall of the support frame, a vibrating knife head fixedly connected to the bottom of the lifting block, a worm gear ring fixedly connected to the outer wall of the rotating block, a worm gear meshing with the outer wall of the worm gear ring, both ends of the worm gear rotatably connected to the outer wall of the support block, a helical gear set provided at the right end of the worm gear, one helical gear in the helical gear set fixedly connected to the right end of the worm gear, a cross rotating sleeve fixedly connected to the inner wall of the other helical gear in the helical gear set, a lifting plate rotatably connected to the outer wall of the cross rotating sleeve, and a cross rotating rod slidably and rotatably connected to the inner wall of the cross rotating sleeve.

[0007] As a further description of the above technical solution: The adjustment mechanism also includes a support frame, the bottom of which is fixedly connected to the top of the support block, and a motor is fixedly connected to the top of the support frame.

[0008] As a further description of the above technical solution: The adjustment mechanism also includes a pulley assembly, the inner wall of which is fixedly connected to the outer wall of an output shaft of the motor.

[0009] As a further description of the above technical solution: The adjustment mechanism also includes an electric actuator, the bottom of which is fixedly connected to the top of the support frame, and the inner rod of which is fixedly connected to the top of the lifting block.

[0010] As a further description of the above technical solution: The adjustment mechanism also includes a second motor, the outer wall of which is fixedly connected to the outer wall of the cutting table. A screw is fixedly connected to the output end of the second motor, and the outer wall of the screw is threadedly connected to the inner wall of the translation frame through a threaded sleeve.

[0014] This utility model has the following beneficial effects: 1. In this utility model, by setting an adjustment mechanism, the synchronous angle adjustment of multiple sets of vibrating cutter heads can be realized. There is no need to configure a separate drive component for each cutter head, which reduces the manufacturing cost and maintenance difficulty of the equipment. The meshing transmission of the worm and worm wheel ring has a self-locking characteristic. After the adjustment is completed, the cutting angle of the vibrating cutter head can be accurately locked to avoid angle deviation caused by external force, thereby improving the stability and accuracy of the cutting operation.

[0015] 2. In this utility model, by setting a switching mechanism, the independent disconnection of the adjustment function of a single set of vibrating cutter heads is realized, which can flexibly adapt to diverse cutting needs. When the workpiece has a local irregular structure, and some cutter heads need to maintain a fixed angle while others need to adjust their angle, this design can accurately control the adjustment range, avoid unrelated cutter head misoperation, and improve the flexibility and accuracy of processing.

The vibrating cutter head 216 is fixedly connected to the bottom of the lifting block 215. The vibrating cutter head 216 is the execution component that directly cuts the workpiece. A worm gear ring 217 is fixedly connected to the outer wall of the worm gear ring 217. The worm gear ring 217 meshes with the worm 218, converting the rotation of the worm 218 into its own rotation. The worm 218 is meshed with the outer wall of the worm gear ring 217 and is used to drive the worm gear ring 217 and the rotating block 213 to rotate. Both ends of the worm 218 are rotatably connected to the outer wall of the support block 212. A helical gear set 219 is provided at the right end of the worm 218.

[0020] Reference Figures 2-4The adjustment mechanism 2 also includes a support frame 223, which is used to fix the motor 224. The bottom of the support frame 223 is fixedly connected to the top of the support block 212, and the top of the support frame 223 is fixedly connected to the motor 224. The motor 224 provides power for the angle adjustment of multiple sets of vibrating cutter heads 216. The adjustment mechanism 2 also includes a pulley set 225, which is used to transmit the power of the motor 224 to the cross rod 222. The inner wall of the pulley set 225 is fixedly connected to the outer wall of the output shaft of the motor 224. The adjustment mechanism 2 also includes an electric push rod 226, which is used to drive the lifting block 215 and the vibrating cutter head 216 to rise and fall. The bottom of the electric push rod 226 is fixedly connected to the top of the support frame 214. The electric actuator 226 is fixedly connected to the top of the lifting block 215. The adjustment mechanism 2 also includes a second motor 227, which provides power for the lateral movement of the translation frame 211.

[0021] Reference Figure 4 The switching mechanism 3 includes a hydraulic rod 311, which is used to drive the lifting plate 221 to rise and fall to control the meshing state of the helical gear set 219. The bottom of the hydraulic rod 311 is fixedly connected to the inner wall of the support block 212, and the inner rod of the hydraulic rod 311 is fixedly connected to the bottom of the lifting plate 221.

[0022] Working principle: When multiple vibrating cutter heads 216 need to be adjusted synchronously, the motor 224 can be started, causing the output shaft of the motor 224 to drive the pulley assembly 225 fixedly connected to the outer wall to rotate. Through the transmission connection of the pulleys and belt, multiple cross rods 222 can be driven to rotate synchronously. The cross rods 222 then drive the cross sleeve 220, which is slidably and rotatably connected to the outer wall, to rotate. The cross sleeve 220 drives the helical gear assembly 219 fixedly connected to the outer wall to rotate. Through the transmission connection of the two helical gears, the worm gear 218 is driven to rotate. When the worm gear 218 is activated, it drives the worm wheel ring 217, which is meshed with the outer wall, to rotate. The worm wheel ring 217 then drives the rotating block 213, which is fixedly connected to the inner wall, to rotate. This rotation of the rotating block 213 drives the support frame 214 to rotate, thereby adjusting the cutting angle of the vibrating cutter head 216. This allows for simultaneous adjustment of the cutting angle of multiple sets of vibrating cutter heads 216. By activating the electric push rod 226, the electric push rod 226 pushes the lifting block 215 to slide on the inner wall of the support frame 214, allowing the height of the vibrating cutter head 216 to be adjusted according to the lifting of the lifting block 215.

[0023] When a certain set of vibrating cutter heads 216 does not require adjustment, the hydraulic rod 311 can be activated to push the lifting plate 221 upward. The limit rod 312 can limit the lifting of the lifting plate 221, so that the lifting plate 221 drives one of the helical gears in the helical gear set 219 to rise, so that the two helical gears are no longer in a meshing state. Therefore, the cutting angle of a certain set of vibrating cutter heads 216 can no longer be adjusted by the worm 218 and the worm ring 217.

[0024] By starting motor 227, the output end of motor 227 drives the fixedly connected screw 228 to rotate. Under the limiting action of limit rod 229, the translation frame 211 is moved, thereby adjusting the cutting position of vibrating cutter head 216.

[0025] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
