Description

Technical Field

[0001] This utility model relates to the field of cutting device technology, and in particular to a cutting device for processing plastic parts. Background Technology

[0002] Plastic parts refer to components or accessories manufactured using synthetic or natural polymers (plastics) as the main raw materials through molding processes such as injection molding, extrusion, blow molding, and compression molding. Processing and cutting equipment is a key piece of equipment in the post-processing or molding of plastics, specifically used to accurately cut plastic raw materials (sheets, rods, pipes, profiles, injection molded parts gates and flash), semi-finished products, or molded parts into the required size and shape.

[0003] In the field of plastic parts processing and manufacturing, cutting is a key post-processing step. Traditional plastic parts cutting devices mostly adopt the working principle of mechanical stamping or reciprocating sawing. Traditional clamps are mechanical clamping. For plastic parts with irregular shapes or those that have already been precision machined, excessive clamping force can easily cause surface damage or deformation. At the same time, under the vibration of stamping or sawing, the workpiece is prone to slight displacement, resulting in cutting accuracy exceeding tolerance. Utility Model Content

[0019] like Figures 1-5 As shown, the device includes a housing 1, an operation panel 2 for controlling the whole device is mounted on the outer end of the housing 1, a flexible arc rod 3 that can slide and move to flexibly hold plastic parts is provided on the housing 1, a displacement adjustment component 5 for quick positioning and adjustment is provided on the outer side of the flexible arc rod 3 on the housing 1, and a cutting module 4 for processing and cutting plastic parts is mounted in the displacement adjustment component 5.

[0020] like Figures 2-3 As shown, the inside of the box 1 is connected to a pneumatic operating table 104, and the outside of the box 1 is equipped with a pneumatic box 103 that communicates with the pneumatic operating table 104. Several sets of pneumatic holes 105 are distributed on the pneumatic operating table 104, and installation clamps 109 are installed between two sets of pneumatic holes 105.

The pressure-bearing frame 111 has a first sliding groove 107 and a second sliding groove 108 respectively opened in the longitudinal and transverse directions near the edge. The pneumatic operating table 104 has a third sliding groove 112 on both sides for sliding the flexible arc rod 3. Support seats 102 are fixed at the corners of the bottom of the box 1. Maintenance doors 101 are symmetrically installed on the box 1. A vibration isolation sleeve 106 is attached to the inner side of the pressure-bearing frame 111.

[0021] like Figures 3-4As shown, elastic rods 301 are installed at both the top and bottom of the flexible arc rod 3. Each elastic rod 301 contains a spring-rubber damper. Several sets of airbags 302 are linearly mounted on the elastic rods 301. Connecting arms 305 are installed at both ends of the flexible arc rod 3. Pressure sensors are installed inside each airbag 302. A rotating rod 303 connects the connecting arm 305 to the flexible arc rod 3. A torque module 304 is connected to the outer end of the rotating rod 303. The torque module 304 drives the rotating rod 303 to adjust the connecting arm 305 and the flexible arc rod 3. In the operation of the section, the end of the connecting arm 305 away from the rotating rod 303 is connected to the guide arm 306. A first steering rod 307 is provided between the guide arm 306 and the connecting arm 305. One end of the first steering rod 307 is connected to the drive motor 308. The drive motor 308 drives the first steering rod 307 to drive the guide arm 306 and the connecting arm 305 to turn.

The displacement adjustment assembly 5 includes a first connecting frame 501 and a second connecting frame 506 arranged perpendicular to the first connecting frame. A sliding sleeve 502, which is fixedly connected to the second connecting frame 506 and mounted on the first connecting frame 501, is fitted on the first connecting frame 501. The center of the frame 501 is provided with a push rod that drives the sliding sleeve 502 to move. One end of the push rod is connected to a cylinder 503. The end of the push rod away from the cylinder 503 is provided with a limiter 504. The cylinder 503 drives the push rod to drive the sliding sleeve 502 and the second connecting frame 506 to move synchronously along the first connecting frame 501. The end of the second connecting frame 506 away from the first connecting frame 501 is connected to a third connecting frame 508. A telescopic sleeve 507 is provided between the third connecting frame 508 and the second connecting frame 506. The lower ends of the third connecting frame 508 and the first connecting frame 501 are both connected to a second slider 510. The outer ends of the third connecting frame 508 and the first connecting frame 501 are respectively provided with a second lithium battery pack 505 and a third lithium battery pack 509. The spring-rubber damper inside the flexible arc rod 3, the vibration isolation sleeve 106 (usually made of high-damping polyurethane material) inside the pressure-bearing frame 111, and the rigid structure of the entire system (the housing 1 and the pressure-bearing frame 111 are made of 6061-T6 aluminum alloy and CNC machined) together constitute a multi-layer vibration reduction system. This system can effectively absorb and isolate the vibration generated by the cutting module 4 during operation, eliminate the slight displacement of the workpiece during processing, and thus ensure extremely high cutting accuracy.

[0023] Working principle: First, the operator places the plastic part to be cut on the pneumatic operating table 104. The equipment is started via the control panel 2, and the pressure box 103 (with built-in vacuum pump) begins to work, generating negative pressure at the pressure port 105 of the pneumatic operating table 104, initially adsorbing and fixing the workpiece onto the table surface. This step provides basic fixing force, preventing macroscopic movement of the workpiece; After initial fixation, the control system starts the drive motor 308 and torque module 304. The torque module 304 drives the rotating rod 303, which in turn drives the connecting arm 305 and the flexible arc rod 3 to extend from the third slide groove 112 on both sides of the housing 1 and close towards the workpiece. At the same time, the drive motor 308 adjusts the angle of the guide arm 306 through the first steering rod 307, so that the flexible arc rod 3 approaches the workpiece contour in the best posture. When the airbag ball 302 on the flexible arc bar 3 and the small claw 312 at the end of the arc frame 311 (the contact surface is a silicone airbag layer 313) come into contact with the workpiece surface, the internal HM series pressure sensor begins to provide real-time feedback of pressure data. Based on feedback, the system intelligently adjusts the output of the drive motor 308 and the torque module 304, so that each contact point "embraces" the workpiece with a uniform and safe force, and completes the final adaptive flexible clamping. The entire clamping process is like having a flexible, fully enclosed fixture custom-made for the workpiece; After the workpiece is firmly and flexibly fixed, the displacement adjustment component 5 starts to work. The cylinder 503 drives the push rod, pushing the sliding sleeve 502 and the second connecting frame 506 fixed thereto to move precisely along the first connecting frame 501 (using a high-precision linear optical axis) to the cutting start position. When the Y-axis position needs to be adjusted, the telescopic sleeve 507 allows the third connecting frame 508 to extend and retract. The cutting module 4 (such as a high-speed spindle with a milling cutter or laser head) mounted on the second connecting frame 506 is activated under the command of the control system, performing high-speed, high-precision cutting operations on the workpiece along a preset path. The vibrations during this process are effectively absorbed by the flexible clamping system and the shock-absorbing structure. After cutting is completed, cutting module 4 stops and resets. Torque module 304 and drive motor 308 move in opposite directions, causing flexible arc rod 3 to release the workpiece and retract to both sides of housing 1. The pneumatic operating table 104 releases negative pressure, allowing the operator to remove the processed part.

[0024] Specifically, the displacement adjustment component 5, cutting module 4, and flexible clamping unit all adopt a modular design, connected via grooves, sliders (the first slider 309 and the second slider 510 use chrome-plated linear bearings) and standard interfaces, facilitating maintenance and replacement. Each module is powered by an independent lithium battery pack (such as the first, second, and third lithium battery packs 509), with clear wiring, reducing internal electromagnetic interference. Meanwhile, the control panel 2 integrates all control functions, providing a user-friendly human-machine interface. The device has a wealth of sensor interfaces and control ports, and can be easily integrated with vision positioning systems, temperature monitoring (such as adding an infrared temperature sensor like MLX90614 to the cutting module 4) or robotic arm automatic loading and unloading units in the future, with huge potential for intelligent and automated upgrades. Cutting module 4: It can be replaced with a high-speed electric spindle (such as an 800W air-cooled spindle), an ultrasonic cutting knife or a small laser according to specific process requirements. It is fastened to the second connecting frame 506 through the sliding sleeve 502 and its position is adjustable. Torque module 304: Preferably a servo motor with an integrated encoder, such as the DYNAMIXEL series, which can precisely control the rotation angle and torque. The pneumatic operating table 104 is essentially a platform with a built-in multi-chamber vacuum adsorption zone. The "pneumatic port 105" is connected to a vacuum generator to generate adsorption force.

[0025] Mounting clamps 109 and clamping holes 110: Standardized interfaces for mounting and securing various molds or special fixtures, increasing the versatility of the equipment.

[0026] Elastic rod 301: A flexible component with an integrated spring rubber damper, whose main function is to provide radial cushioning and elasticity.
