Description

Technical Field

[0001] This utility model relates to a cutting mechanism, specifically a rapid positioning cutting mechanism, and belongs to the field of cutting technology. Background Technology

[0002] Cutting machines are used to precisely cut target objects. The positioning mechanism is essential in this process. It can accurately control the position and orientation of the target object in the placement area. Its key role is to ensure that the target object is firmly fixed and to prevent accidental movement or deformation during cutting, thereby ensuring high precision in the position and size of the cut, improving the consistency of repeated positioning and overall processing efficiency.

[0003] A search revealed a fully automatic cutting machine with rapid positioning, disclosed in Chinese Patent Publication No. CN219926133U. The machine includes a base, brackets fixedly installed on both sides of the base, a fixed frame fixedly installed on the top surface of the brackets, a cylinder inside the support rod, a cutter installed at the output end of the cylinder, a groove on the top surface of the base, and a sliding groove on the top surface of the base.

[0004] While the above solution can achieve positioning and cutting, there is still room for improvement in practical applications. Because the current device requires a cumbersome process to insert the insert into each groove for positioning, it not only fails to provide stepless adjustment and positioning of the material, but also has a low degree of automation, which seriously affects the cutting efficiency. Therefore, we provide a cutting mechanism with rapid positioning to solve the above problems. Utility Model Content

[0026] This utility model provides a cutting mechanism for rapid positioning.

[0027] Please see Figure 1 It includes a cutting frame 1, and a power supply is fixedly installed on the outer surface of the cutting frame 1. The power supply can provide power to the electrical equipment in this application.

[0028] Please refer to it again. Figure 2 , Figure 3 and Figure 4A cutting positioning mechanism 2 is provided above the cutting frame 1. The cutting positioning mechanism 2 includes a carrier box 201. The bottom surface of the carrier box 201 is fixedly connected to the cutting frame 1. An active screw 202 is rotatably connected to the inner wall of the carrier box 201. An adjusting box 203 is threadedly connected to the outer surface of the active screw 202. The outer surface of the adjusting box 203 is slidably connected to the cutting frame 1. By driving the active screw 202 to rotate, the adjusting box 203 can be driven to slide horizontally in the inner wall of the carrier box 201 synchronously.

[0029] The inner wall of the regulating box 203 is slidably connected to the gear frame 204, and the inner wall of the bearing box 201 is rotatably connected to the drive rod 205. Two drive motors are fixedly installed inside the bearing box 201. The output ends of the two drive motors are fixedly connected to the active screw 202 and the drive rod 205, respectively. The outer surface of the cutting frame 1 is integrated with the control buttons for the two drive motors. The two drive motors can be started and stopped by the control buttons. The drive motors are common electrical devices in the prior art, so they are not shown in the figure. This application will not elaborate on their model and internal structure. They can also be replaced by other power sources.

[0030] A driven rod 206 is rotatably connected to the inner wall of the regulating box 203. A meshing wheel 207 is fixedly connected to the outer surface of the driven rod 206. The outer surface of the meshing wheel 207 meshes with the gear frame 204. By driving the meshing wheel 207 to rotate, the gear frame 204 can be effectively driven to slide vertically in the inner wall of the regulating box 203.

[0031] A bevel gear 208 is fixedly connected to one end of the driven rod 206. A bevel gear 209 is fixedly connected to the outer surface of the bevel gear 208. A connecting pipe 210 is fixedly connected to the outer surface of the bevel gear 209. The outer surface of the connecting pipe 210 is rotatably connected to the regulating box 203. By driving the bevel gear 209 to rotate, the bevel gear 208 can be driven to rotate simultaneously. The connecting pipe 210 effectively limits the bevel gear 209, making the meshing of the bevel gear 209 and the bevel gear 208 more stable.

[0032] The outer surface of the drive rod 205 is provided with a sliding groove 211. The inner walls of the bevel gear 209 and the connecting pipe 210 are both fixedly connected with sliding blocks 212 that are adapted to the sliding groove 211. Through the coordinated action of the sliding groove 211 and the sliding blocks 212, when the bevel gear 209 on one end of the drive connecting pipe 210 rotates, it does not affect the synchronous horizontal movement of the bevel gear 209.

[0033] A limiting slide rod 213 is fixedly connected to the inner wall of the carrier box 201. The outer surface of the limiting slide rod 213 is slidably connected to the adjusting box 203. A pointer 214 is fixedly connected to the outer surface of the adjusting box 203. The outer surface of the pointer 214 is slidably connected to the carrier box 201. By setting the limiting slide rod 213, the adjusting box 203 becomes more stable during movement. The outer surface of the carrier box 201 is provided with scale lines. The positioning adjustment can be intuitively performed through the synergistic effect of the scale lines and the pointer 214.

[0034] Please refer to it again. Figure 1 , Figure 3 and Figure 5 An auxiliary mechanism 3 is provided above the cutting frame 1. The auxiliary mechanism 3 includes a mounting plate 301. The top surface of the mounting plate 301 is fixedly connected to the toothed frame 204. The bottom surface of the mounting plate 301 is fixedly connected to the cutting blade 302. A limit rod 303 is slidably connected to the inner wall of the mounting plate 301. A pressure plate 304 is fixedly connected to one end of the limit rod 303. A stop is fixedly installed at the end of the limit rod 303 away from the pressure plate 304. The stop can limit the limit rod 303 and effectively prevent the limit rod 303 from slipping out of the mounting plate 301. The bottom surface of the pressure plate 304 is lower than the cutting blade 302, so the bottom surface of the pressure plate 304 will contact the material first when the mounting plate 301 is driven.

[0035] A support spring 305 is sleeved on the outer surface of the limiting rod 303. The two ends of the support spring 305 are fixedly connected to the mounting plate 301 and the pressure plate 304 respectively. The limiting rod 303 effectively limits the support spring 305, making the support spring 305 more stable during the expansion and contraction process. The elasticity of the support spring 305 effectively supports the pressure plate 304, making the pressure plate 304 press down on the material more firmly.

[0036] The structural diagrams of the components shown in the attached figures are exemplary. The specific implementation should be adapted and optimized by considering the functional requirements, assembly conditions and process limitations in the actual application scenario, and adjusting the structural parameters, size specifications and connection methods accordingly.

[0037] Working principle: First, by driving the active screw 202 to rotate, the regulating box 203 can move horizontally within the inner wall of the bearing box 201. The movement of the regulating box 203 drives the gear frame 204 to move, and the movement of the gear frame 204 drives the pressure plate 304 on the bottom surface of the mounting plate 301 to move synchronously. During the movement of the pressure plate 304, combined with the pointer 214 and the scale lines on the surface of the bearing box 201, the pressure plate 304 can be automatically positioned automatically and steplessly. Through the coordinated action of the driving rod 205 and the sliding slot 211 and sliding block 212, the bevel gear 209 at one end of the connecting pipe 210 can be effectively driven to rotate. The rotation of the bevel gear 209 drives the bevel gear 208 to rotate through the meshing force. The rotation of the bevel gear 208 drives the driven rod 206 to rotate. The rotation of the moving rod 206 drives the meshing wheel 207 to rotate. The rotation of the meshing wheel 207, through the meshing force, drives the mounting plate 301 on the bottom surface of the gear frame 204 to move downward. The downward movement of the mounting plate 301 drives the cutting blade 302, which is positioned, to move downward simultaneously, effectively cutting the material. This design not only improves the compatibility of cutting but also completely solves the problem of cumbersome adjustment steps in existing devices, greatly improving the cutting efficiency of this device. Secondly, because the bottom surface of the pressure plate 304 is lower than the cutting blade 302, the pressure plate 304 will first contact the material when it moves downward. With the elasticity of the support spring 305, the material is effectively pressed on both sides, preventing the material from shifting position due to the cutting pressure of the cutting blade 302. This significantly improves the cutting quality of this device.
