Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of laser cutting positioning, and particularly relates to a positioning system based on detection type base laser cutting. BACKGROUND

[0002] One of the core functions of the existing power conversion system is to convert high voltage into low voltage, and the power conversion system comprises an isolation switch. Before use, the isolation switch needs to be detected, for example, the stability of opening and closing is tested, whether the contact between the contact support and the contact is good is detected, whether the resistance value is consistent is tested, whether the error is within 0.3A, etc. The detection base used adopts a square tube as a base, and some structures are installed inside and outside the square tube to assemble a detection base to detect the isolation switch. If the square tube is damaged during processing, the detection work of the isolation switch will be affected.

[0003] At present, when the square tube is used as a detection base, laser cutting is needed. Because the square tube is hollow, molten slag and splashes will be generated during laser cutting, and high-temperature waste after cutting will also be generated. If these substances enter the inside of the square tube, not only the size accuracy and surface quality of the hole will be affected, but also the inner wall of the square tube will be easily damaged. Moreover, because laser has penetrating property, improper actual laser cutting parameter setting will also affect the inner wall of the square tube. Therefore, the inside of the square tube needs to be filled and protected. Because the existing detection base needs square tubes with different inner diameters, it is a technical problem to be solved in the field that a processing filling protection structure suitable for square tubes with different inner diameters is designed.

[0036] In order to make the purpose, technical scheme and advantages of the embodiments of the present disclosure clearer, the technical scheme of the embodiments of the present disclosure will be described clearly and completely below in conjunction with the drawings of the embodiments of the present disclosure. Obviously, the described embodiments are part of the embodiments of the present disclosure, rather than all the embodiments. Based on the described embodiments of the present disclosure, all other embodiments obtained by a person of ordinary skill in the art without any inventive effort fall within the protection scope of the present disclosure.

[0037] Embodiment 1, please refer to Figures 1-6The application discloses a positioning system based on a detection type base laser cutting, which comprises a supporting base 1, a pair of positioning bases 2 arranged on the supporting base 1, a square tube 3 arranged between the pair of positioning bases 2, a laser cutting mechanism arranged on the supporting base 1, the laser cutting mechanism comprising a laser, a mechanical hand for driving the laser to move and a controller for controlling the mechanical hand, a turning part 4 arranged outside the square tube 3, the turning part 4 being responsible for switching the machining surface of the square tube 3, and a protection part 5 arranged inside the square tube 3, the protection part 5 not following the rotation during the switching of the machining surface of the square tube 3.

[0038] The protection part 5 comprises an arc-shaped bottom plate 51, two sides of the arc-shaped bottom plate 51 being rotationally connected with material receiving plates 52.

[0039] The material receiving plates 52 have two movement states, the first state being an unfolded state and being responsible for collecting cutting waste, and the second state being a storage state and being convenient for switching the machining surface of the square tube 3.

[0044] The reset member 53 is a high-temperature-resistant spring or a high-temperature-resistant elastic rope, and the arc-shaped bottom plate 51 and the material receiving plate 52 are made of heat-resistant steel or heat-resistant alloy (iron-based alloy, etc.). In use, the material receiving plate 52 is in an unfolded state and can protect the inner side and the inner bottom of the square tube 3 during laser punching on the top surface of the square tube 3, effectively avoiding damage to the inner side and the inner bottom of the square tube 3 caused by sparks and high-temperature waste generated during laser cutting. Moreover, the waste after cutting also falls on the arc-shaped bottom plate 51 or the material receiving plate 52, so that not only the waste is collected, but also the inner bottom of the square tube 3 is prevented from being scalded by the waste with a high surface temperature immediately after cutting.

[0045] Further, the turning part 4 comprises a speed reducer motor arranged in the positioning base 2, the output end of the speed reducer motor is fixedly connected with a first speed reducer gear 41, a square limiting frame 43 is arranged on the positioning base 2, the outer part of the square limiting frame 43 is fixedly sleeved with a second speed reducer gear 42, and the first speed reducer gear 41 is in meshing connection with the second speed reducer gear 42.

[0046] The speed reducer motor is started, the speed reducer motor drives the first speed reducer gear 41 to rotate, the first speed reducer gear 41 drives the second speed reducer gear 42 to rotate, thereby driving the square tube 3 to rotate by 90 or 180 degrees, so that the processing surface is switched and the laser cutting is performed on the side surface or the bottom surface.

[0047] The inner wall of the square limiting frame 43 is fixedly connected with an elastic pad, so that the clamping is more stable.

[0048] The speed reducer motor is electrically connected with the controller, and the square limiting frame 43 drives the square tube 3 to rotate by 90 or 180 degrees by starting the speed reducer motor.

[0049] Specifically, the supporting base 1 is rotationally connected with a rotating base 64, the rotating base 64 is installed with a driving motor 65, the driving shaft 61 is in spline sleeve plug-in transmission with the driving motor 65 (that is, the driving shaft 61 can be freely pulled out while following the rotation), the driving motor 65 is started, and the driving shaft 61 starts to rotate. The driving motor 65 can be forward or reverse, in work, the rotating base 64 is first rotated, the protection part 5 is inserted into the square tube 3, then the rotating base 64 is rotated, and finally the driving shaft 61 is plugged with the driving motor 65, so that the work can be started.

[0050] Since part of the square tube 3 is a rectangular cross-section structure, according to the internal incircle area, the inner cavity space will change when rotating, at this time, the receiving and folding of the receiving plate 52 is needed, the driving shaft 61 is rotated, the rope winding roller 62 is arranged on the driving shaft 61, the rope winding roller 62 rotates to wind the traction rope 63, so that a pair of receiving plates 52 rotate inward to the storage posture, and the elastic force of the reset member 53 is overcome; when the square tube 3 is switched to the machining surface that needs to be machined, the driving motor 65 is started in the reverse direction again, so that the rope winding roller 62 is in a unwinding state, the receiving plate 52 is unfolded outward under the action of the reset member 53, and abuts against the inner side wall of the square tube 3 to continue to protect and collect waste materials.

[0051] And the above-mentioned protection component 5 is suitable for square tubes 3 with little difference in inner diameter (error within 3-10 cm), and the angle of the receiving plate 52 can be self-adaptively changed according to the inner diameter of the square tube 3.

[0052] Embodiment 2, please refer to Figures 7-8 , the difference between embodiment 2 and embodiment 1 is that the following technical features are added: the inside of the square tube 3 is provided with a supporting component, and the supporting component includes a supporting plate 7, which is responsible for supporting and plugging the notch position during cutting.

[0053] In further provided embodiments of the application, the supporting plate 7 is provided below with a receiving component 8, and the receiving component 8 includes a telescopic member 81, which has two motion states, the first state is a supporting state, which is used to top the supporting plate 7 on the inner top surface of the square tube 3, and the second state is a retracted state, which is used to retract the supporting plate 7 to the intermediate position inside the square tube 3.

[0054] The receiving component 8 includes a rope winding roller 82 fixedly sleeved on the driving shaft 61, the rope winding roller 82 is fixedly wound with a pulling member 83, the end of the pulling member 83 is fixedly connected with the supporting plate 7, and the pulling member 83 is responsible for pulling the telescopic member 81 to the retracted state.

[0055] The pulling member 83 is made of the same material as the pulling rope in embodiment 1.

[0056] In further provided schemes of the application, the telescopic member 81 includes a fixed rod 811 and a supporting rod 812, the supporting rod 812 is hollow inside, the inner top of the supporting rod 812 is fixedly connected with a supporting spring, and the fixed rod 811 is slidingly connected inside the supporting rod 812 and fixedly connected with the supporting spring.

[0057] In the further provided scheme of the present application, the telescopic member 81 comprises a fixed rod 811 and a supporting rod 812, the fixed rod 811 is hollow inside, the inner top of the fixed rod 811 is fixedly connected with a supporting spring (initially in a compressed state, the initial compression amount is 10-15 cm, and the subsequent compression amount can be 15-30 cm, and a spring steel material with relatively large elastic force is adopted), and the supporting rod 812 is slidingly connected to the inside of the supporting rod 812 and is fixedly connected with the supporting spring.

[0058] The supporting rod 812 can stably slide in the vertical direction inside the fixed rod 811, and the supporting plate 7 can also stably slide in the vertical direction.

[0059] In the actual design of the present application, the pulling rope is in a relaxed state, the pulling member 83 is in a straight state, and the inner roller body outer diameter of the rope collecting roller 82 is greater than the inner roller body outer diameter of the rope winding roller 62, so that the supporting plate 7 is first quickly stored in the center of the inner cavity, then a pair of the connecting plates 52 rotate inwardly, and the supporting plate 7 is wrapped in the inner cavity.

[0060] In the present application, the supporting spring is responsible for abutting the supporting plate 7 against the inner top surface of the square tube 3 through the supporting rod 812, thereby supporting and plugging the cutting notch position, so that the cutting edge is smoother, and the square tube 3 is not easy to deform with the filling support of the supporting plate 7.

[0061] In example 3, please refer to Figures 9-11 , the difference between example 3 and example 2 is that the following technical features are added: the supporting plate 7 comprises a plate frame 71 and a plate body 72, the plate frame 71 is rotatably connected to the plate body 72, a plurality of compression springs 76 are arranged in the inside of the plate body 72, the plate frame 71 and the plate body 72 are fixedly connected through the compression springs 76, vertical strip plates 79 are arranged in the plate frame 71 and on the plate body 72, a first clamping block 75 and a second clamping block 77 are respectively arranged on a pair of the vertical strip plates 79, and the end of the pulling member 83 is fixedly connected with the first clamping block 75 (which is different from example 2).

[0062] The plate body 72 has two states of horizontal and inclined, when the pulling member 83 pulls the first clamping block 75 to move, the plate body 72 rotates to an inclined state under the elastic force of the compression spring 76, so that the cutting waste falls.

[0063] By arranging the supporting plate 73 in the plate frame 71, the plate body 72 can be supported, so that the plate body 72 can be tightly abutted on the inner top surface of the square tube 3 under the action of the telescopic member 81.

[0064] Specifically, the bottom of the plate body 72 is fixedly connected with the vertical strip plate 79, the inner bottom surface of the plate frame 71 is fixedly connected with the vertical strip plate 79, the first clamping block 75 is slidingly connected to the vertical strip plate 79 on the plate frame 71, the second clamping block 77 is fixedly connected to the vertical strip plate 79 on the plate body 72, and the end portions of the first clamping block 75 and the second clamping block 77 are provided with elastic portions which are made of elastic metal material, the extrusion force between the elastic portions is greater than the elastic force of the compression spring 76, so that initially the plate body 72 is located in the plate frame 71.

[0065] Specifically, the bottom surface of the plate body 72 and the top surface of the first clamping block 75 are fixedly connected with the magnet blocks 78, the magnet blocks 78 are specifically T-shaped magnets, the magnetic force is greater than the extrusion force between the elastic portions, and the reset spring 74 is fixedly connected between the first clamping block 75 and the inner bottom surface of the plate frame 71.

[0066] When the pulling piece 83 is pulled, the pulling piece 83 pulls the first clamping block 75 to move, overcomes the magnetic force between the magnet blocks 78 and the elastic force of the reset spring 74 and descends, finally moves to the lower side of the second clamping block 77, unlocks the second clamping block 77, and finally the plate body 72 automatically rotates a set angle (15-60 degrees) under the elastic force of the compression spring 76, pours the waste (cut down) located above it into the protection component 5, then the first clamping block 75 moves to the limit position (the position where the reset spring 74 cannot be compressed), the plate frame 71 is pulled to move downward, and the storage is completed.

[0067] When the subsequent driving shaft 61 reverses, the supporting plate 7 moves upward under the elastic force of the supporting spring, the plate body 72 automatically rotates into the plate frame 71, extrudes and shrinks the compression spring 76, and when the pair of magnet blocks 78 approaches, are attracted by the strong magnetic force, so that the first clamping block 75 moves to the upper side of the second clamping block 77, and the magnet blocks 78 are attracted to each other.

[0068] The above only describes certain exemplary embodiments of the application in a descriptive manner, and it is self-evident that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the application.
