[0033] The present invention provides a cutting device to realize automatic cutting of a workpiece 9, thereby improving cutting efficiency.

[0034] The workpiece 9 may be a walkway on a tank container or other plates.

[0035] Combination Figure 1 and Figure 2 The cutting device includes a clamping mechanism for clamping the workpiece 9 and a cutting mechanism for cutting the workpiece 9 clamped by the clamping mechanism.

[0036] The clamping mechanism includes a base 11 , a fixed support seat 121 , a movable support seat 122 , two positioning components, an end limit component and a plurality of pressing members 15 .

[0037] For the convenience of description, the length direction of the base 11 is defined as the longitudinal direction, and the width direction of the base 11 is defined as the transverse direction.

[0038] The base 11 is the foundation of the entire clamping mechanism. Specifically, the base 11 includes a horizontally arranged bottom plate and a reinforcing seat located below the bottom plate. Both ends of the bottom plate extend outwardly beyond the reinforcing seat.

[0039] The fixed support seat 121 and the movable support seat 122 are arranged at two ends of the longitudinal direction of the base 11. The top of the fixed support seat 121 is provided with a horizontal plane extending horizontally.

[0040] A horizontal plane extending horizontally is provided on the top of the movable support seat 122. The horizontal planes on the tops of the fixed support seat 121 and the movable support seat 122 together form a support surface for supporting the workpiece 9.

[0041] The movable support seat 122 can move in the longitudinal direction to approach or move away from the fixed support seat 121. Specifically, the movable support seat 122 moves in the longitudinal direction relative to the bottom plate.

[0042] The base 11 is provided with a slide rail extending in the longitudinal direction. The slide rail is arranged on the bottom plate. A slider is provided at the bottom of the mobile support seat 122, and the slider is slidably matched with the slide rail. The cutting device includes a power mechanism, which is connected to the mobile support seat 122 to drive the mobile support seat 122 to move along the slide rail. The power mechanism is a servo motor.

[0043] Combination Figure 2 and Figure 3 The cutting device preferably further includes a drag chain 16 disposed on the side of the base 11. The drag chain 16 is a connecting member formed by connecting a plurality of tubular units and having a traction protection function. One end of the drag chain 16 is connected to the mobile support seat 122 and can move back and forth with the mobile support seat 122, and the other end of the drag chain 16 is disposed on one side of the base 11. In this embodiment, a support plate 311 is disposed on one side of the reinforcement seat, and the support plate 311 is used to support the drag chain 16.

[0044] Combination Figure 4-Figure 6 , the two positioning components are respectively arranged on the fixed support seat 121 and the movable support seat 122. That is, a positioning component is arranged on the fixed support seat 121, and a positioning component is arranged on the movable support seat 122.

[0045] The positioning assembly includes a fixed positioning member 131 and a movable positioning member 132 arranged on two lateral sides. The movable positioning member 132 can move in the lateral direction to approach or move away from the fixed positioning member 131.

[0046] The fixed positioning member 131 and the movable positioning member 132 of the same positioning assembly are located in the same horizontal direction. The two fixed positioning members 131 are located on the same side of the support surface. The fixed positioning member 131 is plate-shaped and is fixed on the fixed support seat 121 and the movable support seat 122, respectively, and extends upward beyond the support surface. Preferably, the upper portion of the fixed positioning member 131 has a guide surface that is inclined outward from bottom to top.

[0047] The movable positioning member 132 comprises a positioning plate, which extends upwardly beyond the support surface and is used to abut against the workpiece 9 located on the support surface. The upper portion of the positioning plate preferably has a guide surface that is inclined outwardly from bottom to top.

[0048] The movable positioning member 132 also includes a cylinder, which includes a housing and a telescopic rod that is telescopic along the housing, and the telescopic rod extends in the transverse direction. The two housings are respectively fixed on the fixed support seat 121 and the movable support seat 122. The telescopic rod of the cylinder is connected to the positioning plate to drive the positioning plate to move in the transverse direction.

[0049] The workpiece 9 on the support surface is clamped by moving the positioning member 132 , thereby achieving lateral positioning of the workpiece 9 .

[0050] The end stop assembly is used to realize the longitudinal stop of the workpiece 9 on the support surface. Specifically, the end stop assembly includes a fixed stopper 141 and a movable stopper 142 arranged at both ends of the support surface in the longitudinal direction. The fixed stopper 141 is fixed on the fixed support seat 121, and the movable stopper 142 is movably arranged on the movable support seat 122, and the distance between the fixed stopper 141 and the movable stopper 142 can be adjusted.

[0051] Specifically, the fixed stopper 141 extends in the transverse direction and is continuous. The fixed stopper 141 extends upward beyond the support surface and abuts against the end of the workpiece 9 located on the support surface.

[0052] Specifically, the movable limiting member 142 includes a support frame 1421, a limiting block 1422 and a driving member. The support frame 1421 is movably arranged on the movable support seat 122. The limiting block 1422 is fixed to the top of the support frame 1421. The driving member is connected to the support frame 1421 and drives the support frame 1421 to move laterally. The driving member is a cylinder. Preferably, the movable limiting member 142 includes a plurality of limiting blocks 1422 arranged at intervals along the lateral direction. In this embodiment, the number of the limiting blocks 1422 is two.

[0053] Furthermore, a slide groove can be set on the top of the movable support seat 122, and a slider that slides with the slide groove can be set at the bottom of the support frame 1421. When the driving member drives the support frame 1421, the support frame 1421 moves along the slide groove, which not only ensures the moving direction, but also ensures the smoothness of the movement.

[0054] The two fixed positioning members 131 and the fixed limiting member 141 located on the same side and spaced apart along the longitudinal direction together form an L-shaped abutment surface. Therefore, when the workpiece 9 is placed on the support surface, the limitation on two sides thereof is achieved through the L-shaped abutment surface, and then the limitation on the other two sides of the workpiece 9 is achieved through the movement of the movable positioning member 132 and the movable limiting member 142.

[0055] A plurality of pressing members 15 cooperate with the supporting surface to achieve vertical positioning of the workpiece 9 .

[0056] A plurality of pressing members 15 are arranged at intervals along the circumference of the base 11. The fixed support seat 121 is provided with a pressing member 15, and the movable support seat 122 is provided with a pressing member 15.

[0057] The plurality of clamping members 15 are preferably respectively provided at the longitudinal ends of the support surface and the side clamping members 15 arranged at the opposite sides of the support surface. The end clamping members 15 are provided on the fixed support seat 121 and the side clamping members 15 are provided on the movable support seat 122.

[0058] The end pressing member 15 is disposed at intervals along the lateral direction from the fixed positioning member 131. In this embodiment, there are two end pressing members 15, which are arranged at two lateral sides of the fixed positioning member 131.

[0059] There are two side pressing members 15 , which are arranged on two lateral sides of the support surface. In this embodiment, the side pressing members 15 are respectively arranged corresponding to the fixed positioning member 131 and the movable positioning member 132 on the movable support seat 122 .

[0060] Specifically, the pressing member 15 includes a pressing block that can be raised and lowered. The pressing block is driven by a cylinder to achieve the lifting and lowering. In this embodiment, the bottom surface of the pressing block is a horizontal plane to form a pressing surface, which abuts against the upper surface of the workpiece 9 to press the workpiece 9.

[0061] The cross section of the pressing block of the side pressing piece 15 is L-shaped, and includes a longitudinal portion extending in the longitudinal direction and a transverse portion extending in the transverse direction. The longitudinal portion is arranged at the inner end of the transverse portion and extends toward the end pressing piece 15 . The clamping principle of the clamping mechanism is as follows: According to the length of the workpiece 9, the movable support seat 122 is first moved to a suitable position, and then the workpiece 9 is placed on the support surface so that the two sides of the workpiece 9 respectively abut against the fixed positioning member 131 and the fixed limiting member 141, and then the movable positioning member 132 and the movable limiting member 142 are moved closer to the workpiece 9, and the clamping block descends to clamp the workpiece 9, thereby realizing the longitudinal, transverse and vertical limitation of the workpiece 9 and completing the clamping work.

[0062] The clamping mechanism can adjust the distance between the movable support seat 122 and the fixed support seat 121 according to the length of the workpiece 9, thereby adjusting the length of the support surface, and can further adapt to workpieces 9 of different lengths by adjusting the position of the movable stopper 142. At the same time, the positions of the movable positioning member 132 and the movable stopper 142 on the movable support seat 122 can be adjusted according to different processing requirements for the workpiece 9 to avoid the position that needs to be cut.

[0063] For example, when processing the bevel of the walkway, the movable stopper 142 can be adjusted to move the movable positioning member 132 closer to the middle of the walkway and avoid the corner of the walkway. Alternatively, when processing the arc of the walkway, a longitudinally extending side of the walkway is processed into an arc. At this time, the movable stopper 142 can be adjusted to move the movable positioning member 132 closer to the end of the walkway and avoid the middle area of ​​the walkway.

[0064] Therefore, the clamping mechanism can not only clamp workpieces 9 of different sizes, but also meet different processing requirements of the workpiece 9, thereby improving the versatility of the entire cutting device.

[0065] Furthermore, the cutting device further comprises a base 31, on which the base 11 is rotatably arranged, and the base 11 can rotate longitudinally and thus rotate with the workpiece 9. By rotating the clamping mechanism relative to the base 31, the workpiece 9 can be rotated and cut in different postures, further improving the versatility of the cutting device.

[0066] Specifically, the base 31 includes a supporting plate 311 and pillars 312 arranged at both ends of the supporting plate 311 in the longitudinal direction. The cutting device includes a rotating mechanism for driving the base 11 to rotate relative to the base 31.

[0067] The rotating mechanism includes two connecting plates 36 and a rotating driving member. The two connecting plates 36 are rotatably arranged corresponding to the two pillars 312. The two connecting plates 36 are respectively connected to the longitudinal ends of the base 11. In this embodiment, each connecting plate 36 is respectively arranged on the inner side of the pillar 312. The connecting plate 36 adopts a flange plate.

[0068] The output shaft of the rotary drive member extends in the longitudinal direction. The rotary drive member is connected to at least one connecting disk 36 to drive the connecting disk 36 to rotate and then drive the base 11 to rotate.

[0069] In this embodiment, the rotary drive member adopts an RV reducer.

[0070] There is a height difference between the base 11 and the supporting plate 311. The cutting device further comprises a waste collecting member 35, which is provided with a collecting groove with a top opening, and the outer circumference of the collecting groove extends outwardly beyond the supporting surface, so as to collect waste generated by cutting.

[0071] The cutting mechanism includes a mechanical arm 21 and a laser cutting head 22 disposed on the mechanical arm 21 .

[0072] The robot arm 21 is a 6-axis robot arm 21. The laser cutting head 22 performs cutting by laser.

[0073] An anti-collision sensor 23 is preferably provided between the robot arm 21 and the laser cutting head 22. When the anti-collision sensor 23 detects a collision, the laser cutting head 22 stops working.

[0074] The cutting device includes a controller 38. The controller 38 is in communication with the movable support base 122 and is used to control the movement of the movable support base 122 in the longitudinal direction.

[0075] The controller 38 is in communication with the movable positioning member 132 and is used to control the lateral movement of the movable positioning member 132 .

[0076] The controller 38 is in communication connection with the movable limiting member 142 and is used to control the movement of the movable limiting member 142 in the longitudinal direction.

[0077] The controller 38 is in communication connection with the pressing member 15 and is used for controlling the lifting and lowering of the pressing member 15 .

[0078] The controller 38 is in communication connection with the cutting mechanism and is used to control the action of the cutting mechanism to cut the workpiece 9 .

[0079] The controller 38 also controls the rotation of the clamping mechanism.

[0080] Specifically, the controller 38 is provided with an input module. The input module is used to input the size of the workpiece 9 to be processed and the processing requirements. Therefore, when processing a workpiece 9, the size of the workpiece 9 and the processing requirements (such as cutting an arc or cutting a bevel or cutting a bevel and a hand hole) are first input into the controller. After the input is completed, the controller 38 controls the mobile support seat 122 to move to a preset position according to the above signal. The preset position meets the size requirements of the workpiece 9 and the avoidance requirements during cutting. That is, the mobile support seat 122 not only supports one end of the workpiece 9, but also avoids the laser cutting track.

[0081] Then the workpiece 9 is placed on the support surface and abuts against the fixed stopper 141 and the fixed positioning member 131. Next, the controller 38 controls the movable positioning member 132, the movable stopper 142 and the clamping member 15 to start, realize the positioning of all parties, and complete the clamping work.

[0082] At the same time, after the clamping mechanism has clamped, the controller 38 can also control the clamping mechanism to rotate a certain angle to a preset position as needed. Or, due to cutting requirements, the controller 38 controls the clamping mechanism to rotate at a certain speed while the cutting mechanism performs cutting work.

[0083] The cutting device has a high degree of automation through the cooperation of the clamping mechanism and the cutting mechanism, which not only saves time and improves production efficiency, but also reduces labor costs, improves cutting quality, and eliminates the potential safety hazard of on-site safety electric tools injuring people.

[0084] The cutting device has a simple structure, strong versatility, and an avoidance function, and can achieve all-round cutting without dead angles.

[0085] The present invention also provides a cutting method, using the above cutting device. The cutting method comprises the following steps: S11 . According to the size of the workpiece 9 , the distance between the movable support seat 122 and the fixed support seat 121 is adjusted so that two ends of the workpiece 9 are supported on the movable support seat 122 and the fixed support seat 121 , respectively.

[0086] S12, according to the processing requirements of the workpiece 9, adjust the position of the movable limiting member 142, so that the fixed positioning member 131, the movable positioning member 132 and the pressing member 15 on the movable support seat 122 are moved to the preset position. The preset position can avoid the position to be processed.

[0087] For example, when processing the bevel of the walkway, the movable stopper 142 is adjusted to be away from the fixed stopper 141. Therefore, when the walkway is placed on the support surface, the fixed positioning member 131, the movable positioning member 132 and the pressing member 15 provided on the movable support seat 122 are away from the end of the walkway and close to the middle, so as to avoid the processing of the bevel.

[0088] Alternatively, when processing the arc of the walkway, the movable stopper 142 is adjusted to be close to the fixed stopper 141. Therefore, when the walkway is placed on the support surface, the fixed positioning member 131, the movable positioning member 132 and the pressing member 15 provided on the movable support seat 122 are close to the end of the walkway, so as to avoid processing the arc on the walkway. The arc of the walkway is usually processed and formed on the side of one side of the walkway in the width direction and located in the middle.

[0089] S13, placing the workpiece 9 on the support surface, moving the positioning member 132 closer to the workpiece 9, lowering the clamping member 15, and clamping the workpiece 9 on the support surface.

[0090] Specifically, the workpiece 9 is abutted against the L-shaped abutting surface formed by the two fixed positioning members 131 and the fixed limiting member 141, and then the other two sides of the workpiece 9 are limited by moving the movable positioning member 132 and the movable limiting member 142. Then, the clamping member 15 is lowered to clamp the workpiece 9.

[0091] S14, the cutting mechanism cuts the workpiece 9 located on the clamping mechanism.

[0092] Cutting is performed by a cutting mechanism.

[0093] Preferably, when the cutting mechanism is cutting, the clamping mechanism can also rotate, thereby achieving cutting while rotating.
