Abstract
Description
Technical Field
[0001] This utility model relates to the field of special processing technology, and in particular to a magnet adjustment and positioning device for magnetic field-assisted discharge processing. Background Technology
[0002] Electrical discharge machining (EDM) is a special machining method that uses the electro-erosion effect generated by pulsed discharge between two electrodes immersed in a working fluid to remove materials. It is particularly suitable for machining hard, brittle, or high-toughness conductive materials and has wide applications in mold manufacturing, aerospace, and other fields. In recent years, in order to further improve the efficiency, surface quality, and process stability of EDM, magnetic field-assisted EDM technology has become a key research and application direction. This technology improves the discharge channel state, promotes chip removal, and ensures uniform discharge by applying an external magnetic field to the discharge gap. However, in existing magnetic field-assisted EDM devices, the installation and adjustment methods of the magnets are still relatively primitive, generally using fixed or simple manual adjustment structures. This makes it impossible to achieve precise positioning and quantitative adjustment of the magnets in multiple degrees of freedom in space. Consequently, the magnetic field parameters (including intensity and direction) are difficult to flexibly set according to specific processing requirements, and the magnetic field distribution is difficult to reproduce, thus affecting the stability of the processing effect and the comparability of experimental results.
[0003] Therefore, a magnet adjustment and positioning device for magnetic field-assisted discharge machining is proposed. Utility Model Content
[0004] The purpose of this invention is to provide a magnet adjustment and positioning device for magnetic field-assisted discharge machining, so as to solve the problems mentioned in the background art.

[0014] The beneficial effects of this utility model are:
[0015] This invention allows for the adjustment of the linear position of a magnet by pushing a slider on a linear guide rail. Rotating the clamping seat causes the angle adjustment shaft to rotate, which in turn causes the magnet to rotate, thus adjusting the angle of the magnet.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0024] Example:
[0025] like Figure 1-5 As shown, this embodiment provides a magnet adjustment and positioning device for magnetic field-assisted discharge machining, including a non-magnetic base 1, a linear guide rail 2 mounted on the non-magnetic base 1, a slider 3 slidably engaged within the linear guide rail 2, a scale indicator block 4 mounted on the slider 3, a scale 5 mounted on the linear guide rail 2, an angle adjustment shaft 6 rotatably engaged within the slider 3, a turntable 7 fixedly sleeved on the angle adjustment shaft 6, an angle scale 8 mounted on the slider 3, a scale indicator block 9 and a clamping seat 10 mounted on the turntable 7, a casing 11 slidably engaged within the clamping seat 10, and a fixing plate 12 slidably mounted within the casing 11. The non-magnetic base 1 is fixed in a suitable position through the mounting holes on the non-magnetic base 1. The magnet to be fixed is then placed between a pair of casings 11. The pair of casings 11 move and move closer together to enclose the magnet. The fixing plate 12 moves downward to press and fix the magnet, adaptable to magnets of different sizes. The non-magnetic base 1, clamping base 10, and outer shell 11 are made of non-magnetic materials, which avoids magnetic flux short circuits and ensures the accuracy and effectiveness of the magnetic field required for the experiment.
[0026] Pushing the slider 3 on the linear guide rail 2 allows adjustment of the linear position of the magnet. Rotating the clamping base 10 causes the angle adjustment shaft 6 to rotate, which in turn causes the magnet to rotate, allowing adjustment of the magnet's angle. By adjusting the position and angle of the magnet, continuous and precise adjustment of the magnet spacing and magnetic field direction is achieved, enabling the rapid formation of various magnetic field configurations to meet application requirements. Furthermore, when adjusting the linear position and angle, the spacing and angle can be recorded using the scale indicator block 4, scale 5, angle scale dial 8, and scale indicator block 9, respectively. Both spacing and angle can be quantitatively recorded and precisely reset, ensuring the consistency and comparability of a series of experimental data and strongly supporting scientific research.
[0027] To lock the position of the magnet after linear adjustment, a fixing block 13 is installed on one side of the slider 3. A fixing bolt 14 is screwed into the fixing block 13, and a rubber pad is installed at the bottom of the fixing bolt 14. Pushing the slider 3 on the linear guide rail 2 can adjust the linear position of the magnet. After adjustment, tightening the fixing bolt 14 will cause the fixing bolt 14 to pass through the fixing block 13 and press against the linear guide rail 2. The rubber pad at the bottom of the fixing bolt 14 can also increase contact friction, thereby locking the linear position of the magnet.
[0028] To lock the position of the magnet after angle adjustment, a toothed block 15 is installed on the outer periphery of the turntable 7. A locking block 16 is engaged in the tooth gap of the toothed block 15. A guide sleeve 17 is installed on the slider 3. A slide rod 18 is slidably sleeved in the guide sleeve 17. The locking block 16 is installed at the end of the slide rod 18. Both the guide sleeve 17 and the slide rod 18 have fixing grooves 19, and fixing pins 20 are inserted into the fixing grooves 19. After adjustment, pushing the slide rod 18 forward will cause the locking block 16 to engage in the tooth gap of the toothed block 15, thus locking the magnet angle after adjustment. The number of toothed blocks 15 can support the adjustment of the magnet from zero to ninety degrees.
[0029] To drive a pair of outer casings 11 to move and enclose and secure the magnet, a connecting rod 21 is rotatably mounted on one end of a fixing plate 12. A connecting block 22 is slidably engaged within a clamping seat 10. The other end of the connecting rod 21 is rotatably mounted on the connecting block 22. A screw 23 is mounted on the clamping seat 10, and the connecting block 22 is screwed onto the screw 23. The magnet to be secured is placed between the pair of outer casings 11, and then the screw 23 is rotated. The rotation of the screw 23 causes the connecting block 22 to slide upward, which in turn pulls the pair of connecting rods 21 to rotate. The rotation of the pair of connecting rods 21 pulls the pair of outer casings to move closer together and enclose the magnet.
[0030] To secure the wrapped magnet, a fixing screw 24 is screwed onto the outer casing 11. An annular groove 25 is formed in the fixing plate 12. A retaining ring 26 is fixedly sleeved on the fixing screw 24. The retaining ring 26 rotates and engages within the annular groove 25. Rotating the fixing screw 24 into the outer casing 11 causes the fixing screw 24 to move downward, which in turn moves the pressure plate 12 downward, securing the magnet. The rotation of the retaining ring 26 within the annular groove 25 prevents the fixing screw 24 from falling out of the pressure plate 12.
[0031] Working principle: In use, the non-magnetic base 1 is fixed in a suitable position through the mounting holes on the non-magnetic base 1. Then, the magnet to be fixed is placed between a pair of outer casings 11. Rotating the screw 23 causes the connecting block 22 to slide upwards, which in turn pulls a pair of connecting rods 21 to rotate. This rotation pulls the pair of outer casings closer together to enclose the magnet. Rotating the fixing screw 24 into the outer casing 11 causes the fixing screw 24 to move downwards, which in turn moves the pressure plate 12 downwards to press and fix the magnet. This method can accommodate magnets of different sizes. The non-magnetic base 1, clamping base 10, and outer casing 11 are made of non-magnetic material, avoiding magnetic short circuits and ensuring the accuracy and effectiveness of the magnetic field required for the experiment. Pushing the slider 3 on the linear guide rail 2 adjusts the linear position of the magnet. After adjustment, tightening the fixing bolt 14 causes it to pass through the fixing block 13 and press against the linear guide rail 2. The rubber pad at the bottom of the fixing bolt 14 also increases contact friction, locking the linear position of the magnet. Rotating the clamping seat 10 rotates the angle adjustment shaft 6, which in turn rotates the magnet, allowing for angle adjustment. After adjustment, pushing the slide bar 18 forward causes the locking block 16 to engage with the toothed block 15, locking the adjusted magnet angle. The number of toothed blocks 15 supports magnet angle adjustments from zero to ninety degrees. By adjusting the magnet's position and angle, continuous and precise adjustment of the magnet spacing and magnetic field direction is achieved, quickly forming various magnetic field configurations to meet application requirements. In addition, when adjusting the position and angle of the line, the spacing and angle can be recorded by the scale indicator block 4, scale 5, angle scale 8, and scale indicator block 9 respectively. The spacing and angle can be quantitatively recorded and accurately reset, ensuring the consistency and comparability of the series of experimental data and strongly supporting scientific research.
[0032] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
