Description

Technical Field

[0001] This utility model relates to the field of waterjet cutting technology, specifically a CNC waterjet cutting machine with positioning and clamping fixtures. Background Technology

[0002] Waterjet cutting is suitable for high-precision processing applications, such as cutting chemical fibers, wood, leather, rubber, and ceramics, due to its advantages of smooth, flat, burr-free cuts and no heat-affected zone. However, there are still some shortcomings in the actual operation of this type of CNC waterjet cutting machine.

[0003] CNC waterjet cutting machines often only allow for lateral movement adjustment of the waterjet cutting nozzle, making it difficult to automatically and comprehensively adjust the relative vertical height and longitudinal position between the waterjet cutting nozzle and the product to be cut. This results in low applicability of the device and difficulty in meeting flexible cutting needs at different positions. Furthermore, it often involves placing the product directly onto the cutting machine without a positioning and clamping fixture to fix the product in place, leading to poor stability and inaccurate cutting position. To address these shortcomings, we propose a new type of CNC waterjet cutting machine with a positioning and clamping fixture. Utility Model Content

[0004] The purpose of this invention is to provide a CNC waterjet cutting machine with a positioning and clamping fixture to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: A CNC waterjet cutting machine with positioning and clamping fixture, comprising a frame, a PLC controller mounted at one end of the frame, Z-axis hydraulic telescopic cylinders fixed at the four corners inside the frame, the output end of the Z-axis hydraulic telescopic cylinder connected to an X-axis drive housing, a drive seat slidably connected between adjacent X-axis drive housings, a water storage tank and an abrasive storage tank welded to the two ends inside the drive seat, a water pump fixed on the water storage tank, a water inlet pipe connected to the output end of the water pump, and a material pump fixed on the abrasive storage tank. The pump has an abrasive inlet pipe connected to its output end, and a water jet cutting nozzle is connected between the abrasive inlet pipe and the water inlet pipe. Z-axis hydraulic telescopic cylinders are evenly installed between the X-axis drive housing and the frame. Y-axis drive housings are evenly welded to the bottom of the frame. Stepper motors and lead screw guide modules are sequentially installed on both the Y-axis drive housing and the X-axis drive housing. A telescopic cylinder is slidably connected to the top of the Y-axis drive housing. A positioning clamping fixture is connected to the output end of the telescopic cylinder. A pressure sensor is installed at the end of the positioning clamping fixture away from the Y-axis drive housing.

[0006] Preferably, both ends of the X-axis drive housing are provided with guide sleeves, and the bottom of the frame is welded with a guide column that is slidably connected to the guide sleeves.

[0007] Preferably, there are two X-axis drive housings and two Y-axis drive housings.

[0008] Preferably, the positioning clamping fixture and the output end of the telescopic cylinder are connected by screws to form a disassembly and installation structure.

[0009] Preferably, the bottom of the positioning and clamping fixture is evenly and movably connected with guide balls that match the frame, which improves the stability of the positioning and clamping fixture during movement.

[0010] Preferably, a sewage collection chamber is provided at the bottom of the frame.

[0011] Preferably, a filter plate is installed on the top of the sewage collection chamber, and filter holes are evenly distributed on the filter plate.

[0012] Preferably, positioning strips are evenly distributed along the edge of the filter plate, and positioning slots matching the positioning strips are provided on the sewage collection chamber.

[0013] Preferably, the bottom end of the sewage collection chamber is provided with a drainage port, and a sealing plug is threaded onto the drainage port.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] (1) The CNC waterjet cutting machine with positioning and clamping fixtures has optimized its performance by installing telescopic cylinders, etc. The PLC controller simultaneously starts the extension of two telescopic cylinders, which can change the distance between the two positioning and clamping fixtures, realize the clamping and fixing of the product to be cut, and the synchronous drive structure also ensures that the product is positioned in the middle position of the bottom of the machine frame while clamping. Then, the PLC controller controls the stepper motors inside the Y-axis drive housing and the X-axis drive housing to start, and with the transmission action of the corresponding lead screw guide module, the waterjet cutting nozzle can be automatically moved in the X-axis, and the two positioning and clamping fixtures and the clamped product can be automatically moved in the Y-axis. This can flexibly adjust the relative position between the waterjet cutting nozzle and the surface of the product to be cut, which is conducive to realizing continuous cutting at different positions on the surface of the product to be cut and improving processing efficiency. Furthermore, starting the Z-axis hydraulic telescopic cylinder can drive the X-axis drive housing to automatically lift up and down, which is convenient for flexibly adjusting the working height of the waterjet cutting nozzle and further optimizing the cutting effect.

[0016] (2) The CNC waterjet cutting machine with positioning and clamping fixture has optimized its structure by installing a water tank, etc. The user can selectively turn on the pump installed on the abrasive storage tank according to the hardness of the material to be cut. In conjunction with the start of the pump installed on the water tank, when cutting harder products such as glass, water and abrasive are injected into the waterjet cutting nozzle through the water inlet pipe and the abrasive inlet pipe. The waterjet cutting nozzle is then shot out at the cutting position to complete the waterjet cutting function. When cutting ordinary chemical fibers, it is only necessary to turn on the pump installed on the water tank. Thus, the device integrates the water tank and the pump, as well as the abrasive storage tank and the pump, into the drive base, which facilitates flexible switching of cutting methods, meets different cutting needs, and enhances applicability.

[0017] (3) The CNC waterjet cutting machine with positioning and clamping fixture is equipped with a sewage collection chamber, which makes it possible to collect the wastewater generated during CNC waterjet cutting by installing a filter plate on the top of the sewage collection chamber with filter holes evenly arranged on the filter plate. Subsequently, the user only needs to remove and clean the filter plate independently through the plug-in structure composed of positioning inserts and positioning slots, and open the sealing plug on the drainage reserved port at the bottom of the sewage collection chamber to discharge the filtered wastewater. This makes the device realize the advantages of sewage collection and treatment, avoids ground pollution, and makes the device itself easy to clean through the split structure. On the other hand, by setting a pressure sensor on the positioning and clamping fixture, the clamping pressure of the two positioning and clamping fixtures on the product can be monitored in real time, and the monitored data is sent to the PLC controller, which facilitates intelligent control of the clamping force and avoids the situation of being too loose or too tight.

[0025] The drive base 8 has a water storage tank 2 and an abrasive storage tank 6 welded to its two ends respectively. A water pump 1 is fixed on the water storage tank 2. The output end of the water pump 1 is connected to a water inlet pipe 3. A material pump 7 is fixed on the abrasive storage tank 6. The output end of the material pump 7 is connected to an abrasive inlet pipe 5. A water jet cutting nozzle 4 is connected between the abrasive inlet pipe 5 and the water inlet pipe 3.

[0026] In use, the user can selectively turn on the material pump 7 installed on the abrasive storage tank 6 according to the hardness of the material to be cut. In conjunction with the start of the water pump 1 installed on the water tank 2, when cutting harder products such as glass, water and abrasive are simultaneously injected into the water jet cutting nozzle 4 through the water inlet pipe 3 and the abrasive inlet pipe 5. The water jet cutting nozzle 4 then shoots out towards the cutting position to complete the water jet cutting function. When cutting ordinary chemical fibers, only the water pump 1 installed on the water tank 2 needs to be turned on. Thus, by integrating the water tank 2 and the water pump 1, as well as the abrasive storage tank 6 and the material pump 7, into the drive base 8, the device can flexibly switch cutting methods, meet different cutting needs, and enhance its applicability.

[0028] A telescopic cylinder 26 is slidably connected to the top of the Y-axis drive housing 11. The output end of the telescopic cylinder 26 is connected to a positioning clamping fixture 27. A pressure sensor 25 is provided at the end of the positioning clamping fixture 27 away from the Y-axis drive housing 11.

[0029] In use, the PLC controller 18 simultaneously activates two telescopic cylinders 26 to extend, which can change the distance between the two positioning clamping fixtures 27, thereby clamping and fixing the product to be cut. The synchronous drive structure also ensures that the product is positioned in the middle of the bottom of the frame 17 while being clamped. Subsequently, the PLC controller 18 controls the stepper motors 9 inside the Y-axis drive housing 11 and the X-axis drive housing 10 to start. With the transmission action of the corresponding lead screw guide module 19, the water jet cutting nozzle 4 can move automatically in the X-axis, and the two positioning clamping fixtures 27 and the clamped product can move automatically in the Y-axis. This allows for flexible adjustment of the relative position between the water jet cutting nozzle 4 and the surface of the product to be cut, which is conducive to continuous cutting at different positions on the surface of the product to be cut and improves processing efficiency. Furthermore, the activation of the Z-axis hydraulic telescopic cylinder 14 can drive the X-axis drive housing 10 to automatically lift up and down, which facilitates flexible adjustment of the working height of the water jet cutting nozzle 4 and further optimizes the cutting effect.

[0030] Both ends of the X-axis drive housing 10 are provided with guide sleeves 15, and the bottom of the frame 17 is welded with a guide slide column 16 that is slidably connected to the guide sleeves 15.

[0031] Both the X-axis drive housing 10 and the Y-axis drive housing 11 are provided with two;

[0032] The positioning clamping fixture 27 and the output end of the telescopic cylinder 26 are connected by screws to form a disassembly and installation structure.

[0033] The bottom of the positioning and clamping fixture 27 is evenly and dynamically connected with guide balls 24 that match the frame 17, which improves the stability of the positioning and clamping fixture 27 when it moves.

[0034] A wastewater collection chamber 12 is provided at the bottom of the frame 17;

[0035] A filter plate 20 is installed on the top of the sewage collection chamber 12, and filter holes 21 are evenly arranged on the filter plate 20.

[0036] Positioning strips 23 are evenly arranged along the edge of the filter plate 20, and positioning slots 22 that match the positioning strips 23 are provided on the sewage collection chamber 12.

[0037] The bottom end of the sewage collection chamber 12 is provided with a drainage reserved port 13, and a sealing plug is threaded onto the drainage reserved port 13;

[0038] In use, a filter plate 20 is installed on the top of the sewage collection chamber 12, and filter holes 21 are evenly arranged on the filter plate 20 to facilitate the collection of wastewater generated during CNC water jet cutting after filtration. Subsequently, the user only needs to remove the filter plate 20 independently and clean it through the plug-in structure composed of the positioning insert 23 and the positioning slot 22, and open the sealing plug on the drainage reserved port 13 at the bottom of the sewage collection chamber 12 to discharge the filtered wastewater. This makes the device realize the advantages of sewage collection and treatment, avoid pollution of the ground, and make the device itself easy to clean through the split structure.

[0039] In use, according to the embodiments of this application: First, an external power supply is connected. The user can selectively turn on the pump 7 installed on the abrasive storage tank 6 according to the hardness of the material to be cut. Then, in conjunction with the start of the water pump 1 installed on the water tank 2, when cutting harder products such as glass, water and abrasive are simultaneously injected into the water jet cutting nozzle 4 through the water inlet pipe 3 and the abrasive inlet pipe 5. The water jet cutting nozzle 4 then shoots out towards the cutting position to complete the water jet cutting function. For ordinary chemical fiber cutting, only the water pump 1 installed on the water tank 2 needs to be turned on. Thus, the device integrates the water tank 2 and the water pump 1, as well as the abrasive storage tank 6 and the pump 7, into a single drive unit. The seat 8 facilitates flexible switching of cutting methods, meets different cutting needs, and enhances applicability. In actual operation, the PLC controller 18 simultaneously activates two telescopic cylinders 26 to extend, which can change the distance between the two positioning clamping fixtures 27, thereby clamping and fixing the product to be cut. This synchronous drive structure also ensures that the product is positioned in the middle of the bottom of the frame 17 while being clamped. Subsequently, the PLC controller 18 controls the stepper motors 9 inside the Y-axis drive housing 11 and X-axis drive housing 10 to start, and in conjunction with the transmission action of the corresponding lead screw guide module 19, it can drive the water jet cutting nozzle 4 to move automatically in the X-axis, driving the two positioning clamping fixtures 27. The positioning clamping fixture 27 and the product it clamps move automatically along the Y-axis. This allows for flexible adjustment of the relative position between the waterjet cutting nozzle 4 and the surface of the product to be cut, thus facilitating continuous cutting at different positions on the product surface and improving processing efficiency. Furthermore, activating the Z-axis hydraulic telescopic cylinder 14 automatically raises and lowers the X-axis drive housing 10, facilitating flexible adjustment of the working height of the waterjet cutting nozzle 4 and further optimizing the cutting effect. Additionally, by installing pressure sensors 25 on the positioning clamping fixture 27, the clamping pressure of the two positioning clamping fixtures 27 on the product can be monitored in real time, and the monitored data is then sent to the PLC controller 18. This facilitates intelligent control of the clamping force, preventing it from being too loose or too tight. Furthermore, a filter plate 20 is installed on the top of the sewage collection chamber 12, with filter holes 21 evenly distributed on the filter plate 20. This allows for the collection of wastewater generated during CNC water jet cutting after filtration. Subsequently, the user only needs to remove and clean the filter plate 20 independently through the plug-in structure formed by the positioning insert 23 and the positioning slot 22, and open the sealing plug on the drainage reserved port 13 at the bottom of the sewage collection chamber 12 to discharge the filtered wastewater. This allows the device to achieve the advantages of sewage collection and treatment, avoid ground pollution, and make the device itself easy to clean through its split structure.
