Description

Technical Field

[0001] This utility model belongs to the technical field of electrode processing equipment, and specifically relates to a positioning device for electrode processing. Background Technology

[0002] Graphite, as an electrode material, is increasingly widely used due to its advantages such as high machinability, light weight, fast forming, low expansion rate, low loss, and easy correction. Among the processing methods for graphite electrodes, machining is the most common. When machining graphite electrodes, clamping and positioning fixtures are typically used to position the graphite block, and then a CNC engraving machine is used to process the graphite electrode.

[0003] Dust is generated during the processing of graphite electrodes. In the existing technology, most of the positioning devices for electrode processing cannot handle the dust generated during processing, causing the dust to float in the working environment. A large amount of dust in the air not only pollutes the working environment but also causes certain damage to the health of the workers. Utility Model Content

[0004] The purpose of this utility model is to provide a positioning device for electrode processing, so as to solve the problem that most of the positioning devices for electrode processing mentioned in the background art cannot handle the dust generated during processing, resulting in dust floating in the working environment. A large amount of dust in the air not only pollutes the working environment but also causes certain damage to the health of workers.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a positioning device for electrode processing, comprising a worktable, a dust collection component, a support component, and a fixing component. The dust collection component consists of a collection box and a suction fan. The support component consists of a rotary motor and a support plate. The fixing component consists of a protective box and two fixing sleeves. Two connecting rods are movably connected to the surface of the protective box.

[0006] The outer wall of one side of the fixed sleeve is provided with a connecting groove that matches the connecting rod. The surface of the fixed sleeve is provided with a through hole, and a fixing pin is movably connected in the through hole on the surface of the fixed sleeve. The surface of the connecting rod is provided with a fixing hole that matches the fixing pin.

[0007] In a further embodiment, an air intake hood that fits into the collection box is installed outside the air intake pipe of the suction fan, and a through groove for the collection box to move is provided on one side of the outer wall of the workbench.

[0008] In a further embodiment, the output end of the rotary motor is fixed with a rotating shaft, and the outer wall of the rotating shaft is fixed with two connecting blocks that are fixedly connected to the support plate. The surface of the worktable is provided with a rotating groove for the support plate to rotate.

[0009] In a further embodiment, a dual-axis motor is installed on the bottom wall of the inner cavity of the protective box. Both output ends of the dual-axis motor are fixed with guide screws, and the outer wall of the guide screws is threaded with guide blocks that are fixedly connected to the connecting rod.

[0010] In a further embodiment, each of the two fixed sleeves has a movable groove on its opposite surface, a protective pad is movably connected in the movable groove of the fixed sleeve, and a plurality of buffer springs for supporting the protective pad are installed in the fixed sleeve.

[0011] In a further embodiment, a limit ring is fixed to the outer wall of the fixing pin, and a fixing spring for supporting the limit ring is sleeved on the outside of the fixing pin.

[0012] In a further embodiment, a ventilation groove corresponding to the size of the suction hood is provided on one outer wall of the collection box, and a dustproof net is installed in the ventilation groove of the collection box.

[0013] The technical effects and advantages of this utility model are as follows:

[0014] This positioning device for electrode processing uses a suction fan to create negative pressure inside the workbench during electrode processing, which in turn draws the dust generated during electrode processing into a collection box, preventing dust leakage and facilitating centralized dust treatment later. The rotatable support plate seals the workbench after electrode processing is completed, further preventing dust leakage.

[0015] The dual-axis motor drives two fixed sleeves to move towards each other. The distance between the two fixed sleeves can be adjusted according to the required electrode size to fix the electrode between the two fixed sleeves and quickly position the electrode. At the same time, the protective pad and buffer spring can effectively protect the electrode and prevent it from being damaged.

[0016] By using a fixed spring to support the limiting ring, the fixing pin can be inserted into the fixing hole of the connecting rod, thus quickly completing the installation of the fixing sleeve. Pulling the fixing pin upwards separates it from the connecting rod, and pulling the fixing sleeve outwards quickly disassembles it, facilitating later maintenance. This positioning device for electrode processing can effectively handle dust and other impurities generated during electrode processing, preventing dust leakage and pollution of the working environment.

[0024] In the following description, numerous specific details are set forth in order to provide a more thorough understanding of the present invention. However, it will be apparent to those skilled in the art that the present invention can be practiced without one or more of these details. In other instances, certain technical features well-known in the art have not been described in order to avoid confusion with the present invention.

[0025] Unless otherwise defined, the directions mentioned herein, such as up, down, left, right, front, back, inside, and outside, are based on the directions shown in the figures of this utility model, and are explained here together.

[0026] This utility model provides, for example Figure 1-5The positioning device for electrode processing shown includes a worktable 1, a dust collection component, a support component, and a fixing component. The dust collection component consists of a collection box 2 and a suction fan 3. A groove is provided on one outer wall of the worktable 1 for the collection box 2 to move. Two handles are symmetrically fixed to one outer wall of the collection box 2 by bolts. The suction fan 3 is fixed to the outer wall of the worktable 1 by bolts. An air suction hood 4 that fits against the collection box 2 is installed outside the air inlet pipe of the suction fan 3, and the air suction hood 4 is movably connected to the collection box 2. A ventilation groove corresponding to the size of the air suction hood 4 is provided on one outer wall of the collection box 2, and a dustproof net is installed in the ventilation groove of the collection box 2. When the suction fan 3 is working, it can suck air from the collection box 2 in conjunction with the air suction hood 4, so that the collection box 2 and the worktable 1 are under negative pressure. At the same time, the dustproof net can prevent dust from entering the suction fan 3.

[0027] The support component consists of a rotary motor 5 and a support plate 8. The rotary motor 5 is fixed to the top wall of the inner cavity of the worktable 1 by bolts. The output end of the rotary motor 5 is fixed to a rotary shaft 6 by a coupling. The rotary shaft 6 is rotatably connected to the inner wall of the worktable 1 by bearings, thereby ensuring the stability of the rotary shaft 6 during operation. Two connecting blocks 7 are welded to the outer wall of the rotary shaft 6 and fixedly connected to the support plate 8. The surface of the worktable 1 is provided with a rotating groove for the support plate 8 to rotate. When the electrode is placed, the support plate 8 can stably support the electrode. When the electrode is processed, the rotary motor 5 drives the rotary shaft 6 and the support plate 8 to rotate, so that the support plate 8 rotates to a vertical state, which allows the dust generated during electrode processing to fall into the worktable 1.

[0028] The fixed component consists of a protective box 9 and two fixed sleeves 14. Two connecting rods 13 are movably connected to the surface of the protective box 9. A dual-axis motor 10 is bolted to the bottom wall of the inner cavity of the protective box 9. The two output ends of the dual-axis motor 10 are fixed with guide screws 11 through couplings. The thread grooves of the two guide screws 11 are opposite. The outer wall of the guide screw 11 is threaded with a guide block 12 that is fixedly connected to the connecting rod 13. The surface of the protective box 9 is provided with a guide groove for the guide block 12 to move.

[0029] The bottom of the fixing sleeve 14 is provided with a connecting groove that matches the connecting rod 13. The surface of the fixing sleeve 14 is provided with a through hole, and a fixing pin 15 is movably connected in the through hole on the surface of the fixing sleeve 14. The surface of the connecting rod 13 is provided with a fixing hole that matches the fixing pin 15. A limit ring 16 is welded to the outer wall of the fixing pin 15, and a fixing spring 17 for supporting the limit ring 16 is sleeved on the outside of the fixing pin 15. The fixing spring 17 supports the limit ring 16, so that the fixing pin 15 can be inserted into the fixing hole of the connecting rod 13, and the installation of the fixing sleeve 14 can be completed quickly. Pulling the fixing pin 15 upward will separate the fixing pin 15 from the connecting rod 13, and pulling the fixing sleeve 14 outward will quickly complete the disassembly of the fixing sleeve 14, which is convenient for later maintenance.

[0030] Each of the two fixed sleeves 14 has a movable groove on its opposite surface. A protective pad 18 is movably connected in the movable groove of the fixed sleeve 14. Limiting sliders are fixed on both outer walls of the protective pad 18. Limiting grooves are provided on both inner walls of the fixed sleeve 14 for the limiting sliders to slide. The limiting sliders slide in the limiting grooves of the fixed sleeve 14, which can restrict the movement path of the protective pad 18 and prevent the protective pad 18 from sliding out of the fixed sleeve 14. Multiple buffer springs 19 are installed in the fixed sleeve 14 to support the protective pad 18. The two fixed sleeves 14 can be driven to move towards each other by the dual-axis motor 10. The distance between the two fixed sleeves 14 can be adjusted according to the electrode size to be processed, and the electrode can be fixed between the two fixed sleeves 14 to quickly position the electrode. At the same time, the protective pad 18 and the buffer springs 19 can effectively protect the electrode and prevent damage to the electrode.

[0031] All standard parts used in this utility model can be purchased from the market, and irregular parts can be customized according to the description and drawings. The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts and equipment adopt conventional models in the prior art, and the circuit connection adopts conventional connection methods in the prior art, which will not be described in detail here. The control method of this utility model is through a controller. The control circuit of the controller can be implemented by simple programming by those skilled in the art. The contents not described in detail in this specification belong to the prior art known to those skilled in the art.

[0032] In the description of this utility model, it should be understood that the indicated orientation or positional relationship is based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing this utility model and simplifying the description, and is not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0033] Working principle:

[0034] This positioning device for electrode processing, when in use, places the graphite electrode on the surface of the support plate 8, starts the dual-axis motor 10, drives the two guide screws 11 and guide blocks 12 to move towards each other simultaneously, and with the help of the connecting rod 13, drives the two fixed sleeves 14 to move towards each other. The distance between the two fixed sleeves 14 is adjusted so that the two protective pads 18 are tightly attached to both sides of the electrode, fixing the electrode between the two fixed sleeves 14, quickly positioning the electrode. At the same time, with the help of the protective pads 18 and the buffer springs 19, the electrode can be effectively protected and prevented from being damaged.

[0035] After the electrode is positioned, the rotary motor 5 is started, driving the rotary shaft 6 and the support plate 8 to rotate, so that the support plate 8 rotates to a vertical position. The electrode is then processed by the engraving machine. At the same time, the suction fan 3 is started, and the suction hood 4 is used to create a negative pressure inside the worktable 1, sucking the dust generated during electrode processing into the collection box 2 to prevent dust leakage. After the electrode processing is completed, the suction fan 3 is turned off, and the rotary motor 5 rotates in the opposite direction to reset the support plate 8 and seal the worktable 1, further preventing dust leakage. The dual-axis motor 10 is then reset, and the processed electrode is removed from the surface of the support plate 8.

[0036] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
