Description

Technical Field

[0001] This utility model relates to the technical field of waterjet cutting equipment, and in particular to a fine waterjet cutting device for polyester resin crafts. Background Technology

[0002] Polyester resin handicrafts are widely used in decoration and collection due to their excellent plasticity and appearance. Waterjet cutting, as a cold cutting method, uses high-pressure water jets for processing, offering advantages such as smooth cuts, no thermal stress, and less dust, making it ideal for cutting materials like polyester resin.

[0003] However, polyester resin handicrafts often have complex shapes and require "fine" processing, which places extremely high demands on the precision and flexibility of the cutting. During the cutting process, not only does the cutting jet need to be accurately aligned with the cutting trajectory of the workpiece, but the cutting head also needs to be able to flexibly adjust its height in the vertical direction according to the different thicknesses or three-dimensional features of the handicraft to maintain the optimal cutting distance.

[0004] In existing cutting devices, it is often difficult to simultaneously achieve both convenient horizontal workpiece positioning and precise vertical adjustment of the cutting head. Some simple cutting tables rely on manual handling or rough clamping when adjusting the workpiece position, resulting in poor positioning accuracy and low consistency in repeated processing. Furthermore, their cutting head height adjustment mechanisms are often simple manual locking structures with limited adjustment stroke and inability to achieve automation and precise positioning. This lack of or rudimentary horizontal and vertical adjustment mechanisms leads to low efficiency and difficulty in guaranteeing cutting quality during fine cutting.

[0005] Therefore, this utility model proposes a fine waterjet cutting device for polyester resin handicrafts to overcome the shortcomings of the prior art. Utility Model Content

Detailed Implementation

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Reference Figures 1-5 The present invention provides an embodiment of a fine waterjet cutting device for polyester resin crafts, including a device base 308, a horizontal axis moving stage assembly 2 disposed above the device base 308, and a guide rail support 305 fixedly installed on the device base 308. The device base 308 is used to provide a stable mounting base for the entire device, the horizontal axis moving stage assembly 2 is used to carry and realize the horizontal movement of the workpiece, and the guide rail support 305 provides support and guidance for the vertical movement of the subsequently installed cutting main frame 1.

[0032] Specifically, the device achieves precision cutting through a vertical drive and a horizontal movement mechanism. A guide rail support 305 is fixedly mounted on the equipment base 308. A movable slide 301 is mounted on the guide rail support 305 and can slide vertically along it. The cutting main frame 1 is fixedly mounted on the upper surface of the movable slide 301, enabling the cutting main frame 1 to move vertically. To drive the movable slide 301, a vertical drive motor 3 is fixed to the equipment base 308. The output end of the vertical drive motor 3 is rotatably connected to the lower end of the vertical shaft screw 302 via a coupling 306. The vertical shaft screw 302 passes through the guide rail support 305 and forms a threaded engagement with the vertical shaft seat 303 and the slider 304 mounted on the lower surface of the movable slide 301. When the vertical drive motor 3 operates, it drives the vertical shaft screw 302 to rotate via the coupling 306, thereby driving the vertical shaft seat 303 and the slider 304 threadedly engaged with the vertical shaft screw 302. Block 304 ultimately enables the vertical precise movement of the movable slide 301 together with the cutting main frame 1. At the same time, the horizontal axis movable stage assembly 2 enables the horizontal precise positioning of the workpiece carrier 206. The horizontal axis movable stage assembly 2 includes a horizontal guide rail 207 fixed to the equipment base 308 and a lead screw bearing seat 202. The movable seat 204 is slidably engaged with the horizontal guide rail 207. The bottom of the workpiece carrier 206 is connected to the movable seat 204 through the shaft seat fixing block 205. The manual crank handle 203 is connected to one end of the horizontal axis lead screw 201. The horizontal axis lead screw 201 passes through the lead screw bearing seat 202 and forms a threaded engagement with the movable seat 204. When the operator turns the manual crank handle 203, the horizontal axis lead screw 201 rotates under the support of the lead screw bearing seat 202, thereby driving the movable seat 204 to slide smoothly along the horizontal guide rail 207, and through the shaft seat fixing block 205, it drives the workpiece carrier 206 to complete the horizontal position adjustment.

[0033] Vertical linear guide rails are fixed on both sides of the guide rail support 305. Slider 304s that slide in slidability with the linear guide rails are correspondingly provided on both sides of the movable slide table 301. This guide rail and slider 304 cooperation structure ensures high stability and anti-deflection capability of the movable slide table 301 during vertical movement along the guide rail support 305, providing precise guidance and limiting for vertical drive. The output end of the vertical drive motor 3 is rotatably connected to the lower end of the vertical shaft screw 302 via a coupling 306. The rotational motion of the vertical shaft screw 302 is converted into vertical linear motion of the movable slide table 301 through the threaded engagement between the vertical shaft seat 303 and the slider 304, which are bolted to the lower surface of the movable slide table 301. The movement drives the cutting main frame 1, which is fixedly installed on the upper surface of the movable slide table 301, to achieve automated and high-precision lifting and positioning. At the same time, the cutting main frame 1 is further provided with a lifting adjustment column 104. The lifting adjustment column 104 is a spiral lifting mechanism with an adjustment handwheel for manual rotation at its top. The high-pressure water injection port 101 is fixed on the surface of the lifting adjustment column 104. The output end of the high-pressure water injection port 101 is connected to the sand mixing pipe 102, and the end of the sand mixing pipe 102 is connected to the jet nozzle 103. By manually rotating the adjustment handwheel, the lifting adjustment column 104 can be driven to make slight lifting and lowering, thereby achieving fine-tuning of the height of the jet nozzle 103 to meet extremely demanding cutting precision requirements.

[0034] As a preferred embodiment, the cutting host frame 1 is provided with a lifting adjustment column 104 inside. A high-pressure water injection port 101 is fixed on the surface of the lifting adjustment column 104. The output end of the high-pressure water injection port 101 is connected to the sand mixing pipe 102. The end of the sand mixing pipe 102 is connected to the jet nozzle 103. This structure together forms the water jet supply, sand mixing and spraying path, ensuring the effective formation and delivery of the cutting medium.

[0035] As a preferred embodiment, vertical linear guide rails are fixed on both sides of the guide rail support 305, and sliders 304 that slide in cooperation with the linear guide rails are provided on both sides of the movable slide table 301. The precise cooperation between the linear guide rails and the sliders 304 greatly improves the stability and positioning accuracy of the movable slide table 301 during vertical movement, and effectively reduces the shaking and deviation during the cutting process.

[0036] In a preferred embodiment, both the vertical shaft seat 303 and the slider 304 are fixed to the lower surface of the movable slide 301 by bolts. This bolt fixing method ensures that the vertical shaft seat 303 and the slider 304 are firmly and reliably connected to the movable slide 301, and ensures that the rotation of the vertical shaft screw 302 can be stably and effectively converted into the linear motion of the movable slide 301.

[0037] In a preferred embodiment, the lead screw bearing housing 202 is provided with a bearing for supporting the rotation of the horizontal lead screw 201. The bearing is designed to reduce the frictional resistance of the horizontal lead screw 201 during rotation, improve transmission efficiency and positioning accuracy, and extend the service life of the horizontal lead screw 201.

[0038] As a preferred embodiment, the shaft seat fixing block 205 is an L-shaped connecting block, which connects the upper surface of the movable seat 204 and the side surface of the workpiece bearing platform 206 respectively by bolts. The L-shaped connecting block and the bolt connection method are intended to provide a stable connection, ensuring that the movable seat 204 can stably drive the workpiece bearing platform 206 to move synchronously when sliding on the transverse guide rail 207, avoiding relative displacement and ensuring the accuracy of cutting positioning.

[0039] In a preferred embodiment, the bottom of the equipment base 308 is provided with a drain outlet 307. The drain outlet 307 is designed to drain the water and abrasive mixture generated during the cutting process in a timely manner, keep the working environment of the equipment clean, and prevent the accumulation of waste liquid from affecting the operation of the equipment or corroding the parts.

[0040] As a preferred embodiment, the lifting adjustment column 104 is a spiral lifting mechanism with an adjustment handwheel at the top for manual rotation. This spiral lifting mechanism, in conjunction with the adjustment handwheel, provides a convenient, intuitive, and highly precise fine-tuning method, allowing operators to accurately control minute height changes of the jet nozzle 103 to meet the extremely high requirements for fine cutting of polyester resin crafts.

[0041] Working Principle: The equipment base 308 provides a stable mounting platform for the entire device. A guide rail support 305, a transverse guide rail 207 of the horizontal axis moving table assembly 2, and a lead screw bearing seat 202 are fixedly mounted on top of it. When vertical position adjustment of the workpiece is required, the vertical drive motor 3 starts, and its output end drives the vertical axis lead screw 302 to rotate via a coupling 306. The rotational motion of the vertical axis lead screw 302 is converted into the vertical linear motion of the moving slide 301 through the threaded engagement between the vertical axis seat 303 and the slider 304 mounted on the lower surface of the moving slide 301. Because the moving slide 301 and the linear guide rail on the guide rail support 305 are slidably engaged through the slider 304, the moving slide 301, together with the cutting main frame 1 fixedly mounted on its upper surface, can rise and fall smoothly and accurately in the vertical direction. After vertical drive positioning, the operator can also manually rotate the adjustment handwheel on the top of the lifting adjustment column 104 inside the cutting host frame 1 to drive the spiral lifting mechanism to achieve a small height adjustment of the high pressure water injection port 101, so as to meet the ultimate requirements for cutting precision.

[0042] When the workpiece needs to be adjusted laterally, the operator manually rotates the manual crank 203 of the horizontal axis moving table assembly 2. The manual crank 203 drives the connected horizontal axis lead screw 201 to rotate under the support of the lead screw bearing seat 202. The rotation of the horizontal axis lead screw 201 drives the moving seat 204 to slide smoothly along the horizontal guide rail 207 through the threaded engagement with the moving seat 204. Since the bottom of the workpiece bearing table 206 is connected to the moving seat 204 through the shaft seat fixing block 205, the workpiece bearing table 206 will move laterally accordingly, thereby achieving precise positioning of the workpiece in the horizontal plane.

[0043] High-pressure water enters the sand mixing pipe 102 through the high-pressure water injection port 101 and mixes with the sand to form a high-pressure abrasive jet, which is sprayed out from the jet nozzle 103 to perform fine cutting on the polyester resin crafts located on the workpiece support platform 206. The wastewater generated during the cutting process is discharged through the drain port 307 at the bottom of the equipment base 308 to ensure a clean working environment.
