Description
Technical Field
[0001] This application relates to stone processing equipment, and more particularly to an anti-collision structure, a waterjet sawing device, a machining center, and a waterjet sawing apparatus. Background Technology
[0002] Because the surface of the slate is uneven or the slate may not be placed on an even surface, the waterjet nozzle may hit a protruding part during the waterjet cutting process, thus breaking the nozzle. The waterjet devices in the relevant technology do not have an anti-collision structure, which can easily cause damage to the waterjet. Summary of the Invention
[0003] In view of this, this application provides an anti-collision structure, a waterjet sawing equipment, a machining center, and a waterjet sawing device, which is equipped with an anti-collision device to reduce the probability of the spray gun being broken by impact.
[0004] To achieve the above objectives, this application employs the following technical solution:
[0005] A collision avoidance structure, characterized in that: the collision avoidance structure includes a collision avoidance device fixedly installed on the water jet mounting base of the water jet device; the collision avoidance device includes a collision avoidance bracket fixedly connected to the water jet mounting base, a collision avoidance link movably connected to the collision avoidance bracket, and a collision avoidance ring fixedly installed on the collision avoidance link; the collision avoidance ring is sleeved around the outer periphery of the water jet nozzle of the water jet device and located at the lower end of the water jet nozzle; a collision avoidance sensor for detecting whether the collision avoidance link moves upward relative to the collision avoidance bracket is fixedly installed on the collision avoidance bracket; and an elastic element for driving the collision avoidance link to return downward is connected between the collision avoidance bracket and the collision avoidance link.
[0006] The aforementioned anti-collision structure of this application includes an anti-collision device on the water jet device. Since the anti-collision ring is located on the outer periphery of the water jet spray gun, when the water jet spray gun is about to hit the plate, the anti-collision ring will be squeezed first, thereby pushing the anti-collision linkage to move upward. The anti-collision sensor receives the signal of the anti-collision linkage moving upward and controls the water jet device to stop moving, thereby protecting the equipment and preventing the spray gun from being broken.
[0007] In some embodiments, the anti-collision bracket includes a fixed frame fixedly mounted on a water jet mounting base, an anti-collision plate fixedly mounted on the fixed frame, and a housing fixedly mounted on the anti-collision plate. The anti-collision plate has a telescopic hole in the middle. The anti-collision linkage includes an anti-collision block disposed in the housing and placed above the anti-collision plate, an anti-collision shaft fixedly mounted on the anti-collision block and movable up and down in the telescopic hole, and an anti-collision rod fixedly mounted at the lower end of the anti-collision shaft and located below the anti-collision plate. The anti-collision ring is fixedly mounted on the anti-collision rod. The elastic element is a spring that presses against the upper wall of the housing and the anti-collision block to provide a downward restoring force.
[0008] In some embodiments, the anti-collision sensor is a microswitch that is fixedly mounted on the anti-collision plate and located next to the anti-collision block.
[0009] In some embodiments, the anti-collision structure further includes a sand shield fixedly mounted on the waterjet mounting base and covering the outer periphery of the waterjet gun. The lower end of the sand shield has multiple spaced-apart, vertically extending dividing slits. Since waterjet cutting requires the addition of sand particles, the sand shield is used to prevent water and sand particles from splashing. The dividing slits at the lower end of the sand shield ensure that when it descends and presses against the plate, the strips at the lower end of the sand shield will bend and deform, preventing excessive deformation at the upper end of the sand shield and thus avoiding waterjet cutting into it.
[0010] This application also provides a waterjet sawing device, which includes a waterjet device and the aforementioned anti-collision structure. It also includes a frame, a worktable for placing the board, and a processing mechanism movably connected to the frame. The processing mechanism includes a processing head and a drive system for moving the processing head. The processing head includes a mounting frame, a waterjet lifting bracket slidably connected to the mounting frame in the vertical direction, a waterjet cylinder for driving the waterjet lifting bracket to move up and down, a saw blade cutting mechanism rotatably connected to the lower end of the mounting frame, and a self-rotation drive mechanism for driving the saw blade cutting mechanism to rotate. The waterjet mounting base of the waterjet device is fixedly installed on the waterjet lifting bracket.
[0011] In some embodiments, the waterjet sawing equipment further includes a tool setting block fixedly mounted on the worktable for determining the position of the program origin of the machining head in the machine tool coordinate system. The tool setting block includes a tool setting bracket fixedly mounted on the worktable, a tool setting device fixedly mounted on the tool setting bracket, and a tool setting protective cover covering the tool setting device. The tool setting protective cover is vertically and movably connected to the tool setting bracket via a guide rod. A second spring is connected between the tool setting protective cover and the tool setting bracket to drive the tool setting protective cover upwards to reset. Pressing the tool setting protective cover downwards will allow it to contact the tool setting device. The protective cover around the tool setting device reduces the intrusion of dust and moisture into the tool setting device. During tool setting, the machining head presses down on the tool setting protective cover to contact the tool setting device, through which the program origin can be determined.
[0012] In some embodiments, a control unit is also included, which is connected to both the anti-collision sensor and the processing mechanism. When the control unit receives a signal that the anti-collision linkage has moved upward, it stops the operation of the processing mechanism.
[0013] This application also provides a combination device for machining center and waterjet sawing, which includes the above-mentioned waterjet sawing equipment for cutting sheet metal. The combination device for machining center and waterjet sawing further includes a machining center for grinding the edges of the sheet metal located next to the waterjet sawing equipment, and a transfer device for transferring the sheet metal processed by the waterjet sawing equipment to the machining center.
[0014] This combined unit uses a transfer device to move the sheet metal, which can improve transfer efficiency and processing efficiency.
[0015] In some embodiments, the waterjet sawing equipment and the processing center are spaced apart along the left-right direction. The transfer device includes a slide rail extending along the left-right direction, a robotic arm slidably connected to the slide rail, a suction cup mounted on the robotic arm for adsorbing the sheet material, and a moving mechanism for driving the robotic arm to move left and right. The moving mechanism includes a fixed rack, a gear meshing with the rack, and a moving motor fixedly mounted on the robotic arm for driving the gear to rotate.
[0016] As can be seen from the above technical solution, this application has at least the following advantages and positive effects:
[0017] This application discloses an anti-collision structure, a waterjet sawing equipment, a machining center, and a waterjet sawing device. By installing an anti-collision device on the waterjet device, since the anti-collision ring is located on the outer periphery of the waterjet spray gun, when the waterjet spray gun is about to hit the board, the anti-collision ring will be squeezed first, thereby pushing the anti-collision linkage to move upward. The anti-collision sensor receives the signal of the anti-collision linkage moving upward and controls the waterjet device to stop moving, thereby protecting the equipment and preventing the spray gun from being broken.

[0029] To make the objectives, technical solutions, and advantages of this application clearer, the application will be described in further detail below with reference to the accompanying drawings. The terminology used in the embodiments section of this application is only for explaining specific embodiments and is not intended to limit the application.
[0030] See Figures 1 to 10 This application provides a combined machining center and waterjet sawing device, including a waterjet sawing machine 1 for cutting sheet metal, a machining center 2 disposed next to the waterjet sawing machine 1 for edge grinding of the sheet metal, and a transfer device 3 for transferring the sheet metal processed by the waterjet sawing machine 1 to the machining center 2. This combined device improves transfer efficiency and processing efficiency by using the transfer device 3 to transport the sheet metal.
[0031] The waterjet sawing equipment 1 includes a waterjet device, an anti-collision structure, a frame 4, a workbench 5 for placing the board, and a processing mechanism movably connected to the frame 4. The processing mechanism includes a processing head 6 and a drive system for moving the processing head 6. The processing head 6 includes a mounting frame 61, a waterjet lifting bracket 62 slidably connected to the mounting frame 61 in the vertical direction, a waterjet cylinder 63 for driving the waterjet lifting bracket 62 to move up and down, a saw blade cutting mechanism 64 rotatably connected to the lower end of the mounting frame 61, and a self-rotation drive mechanism for driving the saw blade cutting mechanism 64 to rotate. The anti-collision structure is fixedly installed on the waterjet lifting bracket 62.
[0032] The anti-collision structure includes an anti-collision device 8 fixedly installed on the water jet mounting base 73 of the water jet device 7. The anti-collision device 8 includes an anti-collision bracket 81 fixedly connected to the water jet mounting base 73, an anti-collision connecting rod 82 movably connected to the anti-collision bracket 81, and an anti-collision ring 83 fixedly installed on the anti-collision connecting rod 82. The anti-collision ring 83 is sleeved on the outer periphery of the water jet spray gun 71 of the water jet device 7 and located at the lower end of the water jet spray gun 71. An anti-collision sensor 84 for detecting whether the anti-collision connecting rod 82 moves upward relative to the anti-collision bracket 81 is fixedly installed on the anti-collision bracket 81. An elastic element 85 for driving the anti-collision connecting rod 82 to return downward is connected between the anti-collision bracket 81 and the anti-collision connecting rod 82.
[0033] This anti-collision structure, by setting an anti-collision device 8 on the water jet device 7, and since the anti-collision ring 83 is set on the outer periphery of the water jet spray gun 71, when the water jet spray gun 71 is about to hit the plate, the anti-collision ring 83 will be squeezed first, thereby pushing the anti-collision linkage 82 to move upward. The anti-collision sensor 84 receives the signal of the anti-collision linkage 82 moving upward, and controls the water jet device 7 to stop moving, thereby protecting the equipment and preventing the spray gun from being broken.
[0034] The anti-collision bracket 81 includes a fixed frame 811 fixedly mounted on the water jet device 7, an anti-collision plate 812 fixedly mounted on the fixed frame 811, and a housing 813 fixedly mounted on the anti-collision plate 812. The anti-collision plate 812 has a telescopic hole in the middle. The anti-collision link 82 includes an anti-collision block 821 disposed in the housing 813 and placed on the anti-collision plate 812, an anti-collision shaft 822 fixedly mounted on the anti-collision block 821 and movable up and down in the telescopic hole, and an anti-collision rod 823 fixedly mounted at the lower end of the anti-collision shaft 822 and located below the anti-collision plate 812. The anti-collision ring 83 is fixedly mounted on the anti-collision rod 823. The elastic member 85 is a spring that is pressed against the upper wall of the housing 813 and between the anti-collision block 821 to provide a downward restoring force.
[0035] The anti-collision sensor 84 is a microswitch that is fixedly installed on the anti-collision plate 812 and located next to the anti-collision block 821.
[0036] The waterjet device 7 is also fixedly equipped with a sand shield 72 that covers the outer periphery of the waterjet gun 71. The lower end of the sand shield 72 has multiple dividing slits 721 arranged around its perimeter. Since waterjet cutting requires the addition of sand particles, the sand shield 72 is added to prevent water and sand particles from splashing. The dividing slits 721 at the lower end of the sand shield 72 ensure that when the sand shield 72 descends and presses against the material, the strips at the lower end of the sand shield 72 will bend and deform, preventing excessive deformation at the upper end of the sand shield 72, which could cause the waterjet to cut into the sand shield 72.
[0037] The waterjet sawing equipment 1 also includes a tool setting block 9 fixedly installed on the worktable 5 to determine the position of the program origin of the machining head 6 in the machine tool coordinate system. The tool setting block 9 includes a tool setting bracket 91 fixedly installed on the worktable, a tool setting device 92 fixedly installed on the tool setting bracket 91, and a tool setting protective cover 93 covering the outer periphery of the tool setting device 92. The tool setting protective cover 93 is vertically and movably connected to the tool setting bracket 91 via a guide rod 94. A second spring 95 is also connected between the tool setting protective cover 93 and the tool setting bracket 91 to drive the tool setting protective cover 93 to return to its original position. Pressing the tool setting protective cover 93 downwards will allow it to touch the tool setting device 92. The protective cover covering the outer periphery of the tool setting device 92 can reduce the intrusion of dust and moisture into the tool setting device 92. During the tool setting process, the machining head 6 presses down on the tool setting protective cover 93 to touch the tool setting device 92, through which the program origin can be determined.
[0038] The waterjet sawing equipment 1 also includes a control unit, which is connected to the anti-collision sensor 84 and the processing mechanism respectively. When the control unit receives a signal that the anti-collision linkage 82 moves upward, it stops the operation of the processing mechanism.
[0039] The waterjet sawing equipment 1 and the processing center 2 are spaced apart in the left and right direction. The transfer device 3 includes a slide rail 31 extending in the left and right direction, a robot arm 32 slidably connected to the slide rail 31, a suction cup 33 on the robot arm 32 for adsorbing the board, and a moving mechanism for driving the robot arm 32 to move left and right. The moving mechanism includes a rack 34 fixedly set, a gear 35 meshing with the rack 34, and a moving motor 36 fixedly installed on the robot arm 32 for driving the gear 35 to rotate.
[0040] The following is a brief description of the usage method of the machining center 2 and the sawing waterjet combination device in the above embodiment:
[0041] First, the board is placed on the worktable 5 of the waterjet sawing equipment 1. The processing head 6 performs waterjet cutting or saw blade cutting on the board. After the board is cut, the robotic arm 32 picks up the board and transports it to the processing center 2 for edge grinding or hole grinding.
[0042] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the embodiments of this application, and are not intended to limit them. Although the embodiments of this application have been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein.
