Description

Technical Field

[0001] The utility model relates to the technical field of magnetic core cutting equipment, and more specifically, to a positioning device for a multi-wire cutting machine. Background Art

[0002] Magnetic core refers to a sintered magnetic metal oxide composed of a mixture of various iron oxides. For example, manganese-zinc ferrite and nickel-zinc ferrite are typical core materials. Manganese-zinc ferrite has the characteristics of high magnetic permeability and high magnetic flux density, and has the characteristics of low loss. Nickel-zinc ferrite has extremely high resistivity and low magnetic permeability of less than a few hundred. Ferrite cores are used in coils and transformers of various electronic devices.

[0003] At present, a Chinese patent with application number 202022964870.4 on the market discloses a multi-wire cutting machine, including an upper fixed frame, a lower fixed frame and a support frame. The upper fixed frame and the lower fixed frame are fixedly connected through the support frame. An active motor and a connecting shaft are fixedly connected to one side of the upper fixed frame. The power output end of the active motor is fixedly connected to the motor shaft, and a first cam is fixedly connected to the motor shaft. A rotating bearing is fixedly connected to the connecting shaft, and the connecting shaft is rotatably connected to the second cam through a rotating bearing. A plurality of fixed sleeves are also fixedly connected to the upper fixed frame, and a sliding rod is slidably connected to the fixed sleeve. Rotating wheels are provided on both sides of the sliding rod, and the rotating wheels are rotatably connected to the sliding rod.

A fixed cavity is opened at the bottom of the fixed plate, and a plurality of cutting wires are fixedly connected to the fixed cavity.

[0004] In the above patent, although the pressure is controlled within the tolerable range of the cutting wire by an electric telescopic rod to extend the service life of the cutting wire, the frequency of the reciprocating motion of the sliding rod can be controlled by controlling the speed of the active motor, thereby controlling the cutting efficiency, but the multi-wire cutting machine does not have a positioning mechanism, which causes the cutting wire to shift when cutting the material, which in turn easily produces waste during cutting, thereby reducing work efficiency.

DETAILED DESCRIPTION

[0019] Reference Figures 1 to 5 The utility model is further described in detail.

[0020] A positioning device for a multi-wire cutting machine comprises a workbench 2, a cutting mechanism 1, a positioning mechanism 3 and a guide member 13. A cutting mechanism 1 for multi-wire cutting of magnetic cores is provided at one end of the workbench 2, a positioning mechanism 3 for moving and fixing the magnetic cores is provided at the other end of the workbench 2, and the guide member 13 is placed on the workbench 2 and is located between the cutting position and the positioning mechanism 3.

[0021] The positioning mechanism 3 includes a first motor 31, a screw rod 32, a sleeve 33, a moving block 34, a fixing member 35 and a supporting block 36. A slide groove 4 is provided on the workbench 2. The moving block 34 is placed in the slide groove 4 to slide. The moving block 34 is fixedly connected to the fixing member 35. The first motor 31 is fixed on the workbench 2. The first motor 31 includes a first rotating shaft 5. The first rotating shaft 5 passes through the workbench 2 and extends into the slide groove 4 and is fixedly connected to the screw rod 32. The sleeve 33 is fixed on the slide groove 4. A threaded hole 6 is provided on the moving block 34. The screw rod 32 passes through the threaded hole 6 and is rotatably connected to the sleeve 33. The screw rod 32 is threadedly connected to the threaded hole 6. The supporting block 36 is fixed on the workbench 2 and is placed between the moving block 34 and the cutting mechanism 1.

[0022] By placing one end of the magnetic core on the moving block 34 and fixing it with the fixing member 35, and then fixing one end of the magnetic core on the moving block 34, and placing the other end of the magnetic core on the supporting block 36, and then starting the first motor 31, thereby driving the first rotating shaft 5 to rotate, and then the first rotating shaft 5 drives the screw rod 32 to rotate, and the screw rod 32 extends into the sleeve 33, so that the sleeve 33 plays the role of supporting the screw rod 32, and then under the rotation of the screw rod 32, the moving block 34 moves in the slide groove 4, and then drives the fixing member 35 to move, and then the fixing member 35 drives the magnetic core to move, and then the cutting mechanism 1 is started, and the magnetic core is cut by the cutting mechanism 1. Because the fixing member 35 fixes the magnetic core to a limit position, the magnetic core is prevented from deviating when the cutting mechanism 1 cuts the magnetic core, thereby avoiding the generation of waste and improving work efficiency.

[0023] The fixing member 35 includes a connecting block 7, a first spring 8 and a limiting plate 9. The connecting block 7 is fixed on the moving block 34. Limiting grooves 10 are respectively provided on both sides of the connecting block 7. Two first springs 8 are provided and are respectively placed in the two limiting grooves 10. The limiting plate 9 is L-shaped and extends into the limiting groove 10. The two ends of the first spring 8 are respectively fixedly connected to the inner wall of the limiting groove 10 and the limiting plate 9.

[0024] By pulling the two limit plates 9 so that the limit plates 9 extend out of the limit slots 10, the first spring 8 is driven to extend its output elasticity, and then the magnetic core is placed on the moving block 34. At this time, the two limit plates 9 are released, and the first spring 8 rebounds to drive the limit plates 9 to extend into the limit slots 10 until the two limit plates 9 respectively contact the magnetic core, thereby fixing the magnetic core on the moving block 34, and preventing the magnetic core from shifting when the cutting mechanism 1 cuts the magnetic core, thereby avoiding the generation of waste and improving work efficiency.

[0025] The guide member 13 includes a second spring 131, a connecting rod 132, a clamping plate 133 and a fixing block 134. The fixing block 134 has two fixings on both sides of the workbench 2. The fixing block 134 has a connecting hole 14. The connecting rod 132 passes through the connecting hole 14 and is fixedly connected to the clamping plate 133. The second spring 131 is sleeved on the connecting rod 132, and the two ends of the second spring 131 are respectively in conflict with the clamping plate 133 and the fixing block 134.

[0026] By pulling the connecting rod 132, the connecting rod 132 drives the clamping plate 133 to move, and then the clamping plate 133 squeezes the second spring 131 so that the second spring 131 contracts and generates elasticity. When the magnetic core is placed between the two guide members 13, the connecting rod 132 is loosened to reduce the squeezing force of the second spring 131, and then the clamping plate 133 is pushed by the elasticity of the second spring 131 until the clamping plate 133 contacts the magnetic core, thereby playing a guiding role and further limiting the magnetic core.

[0027] The cutting mechanism 1 includes a cutting line 101, a first rotating roller 102, a second rotating roller 103, a second motor 104, a positioning block 105, a synchronous belt 106, a first gear 107 and a second gear 108. The positioning block 105 is fixed on the workbench 2. The positioning block 105 is provided with a positioning groove 11. The second motor 104 is fixed on the positioning block 105. The second motor 104 includes a second rotating shaft 12. The second rotating shaft 12 passes through the positioning block 105 and extends into the positioning groove 11 to be connected to the first rotating shaft. The movable roller 102 is fixedly connected, the first gear 107, the second gear 108 and the synchronous belt 106 are respectively placed in the positioning groove 11, the synchronous belt 106 is multi-tooth meshed with the first gear 107 and the second gear 108 respectively, the second rotating shaft 12 is fixedly connected to the first gear 107, the second gear 108 is rotatably connected to the inner wall of the positioning groove 11, and the second rotating roller 103 is fixedly connected to the second gear 108, and a cutting line 101 is connected between the first rotating roller 102 and the second rotating roller 103;

[0028] The second motor 104 is started to rotate the second shaft 12, and the second shaft 12 drives the gear and the first rotating roller 102 to rotate. The first gear 107 and the second gear 108 are meshed with the multi-teeth of the synchronous belt 106, and the second gear 108 rotates as the first gear 107 rotates, and the second rotating roller 103 rotates as the second gear 108 rotates. The cutting line 101 is driven to rotate as the first rotating roller 102 and the second rotating roller 103 rotate, thereby achieving cutting of the magnetic core.

[0029] Working principle: first, move the two limit plates 9 outward from the limit groove 10, so that the first spring 8 is stretched to generate elasticity, and then one end of the magnetic core to be processed is placed on the moving block 34, and then the two limit plates 9 are loosened, and then the elasticity of the first spring 8 causes it to contract, thereby driving the two limit plates 9 to move relative to each other until the two limit plates 9 respectively conflict with the magnetic core, and then fix one end of the magnetic core on the moving block 34, and then place the other end of the magnetic core on the supporting block 36, which plays a role in supporting the other end of the magnetic core. At the same time, pull the two connecting rods 132 so that the connecting rod 132 drives the card plate 133 to move relative to each other, and then the card plate 133 squeezes the second spring 131. When the other end of the magnetic core is placed on the supporting block 36, the connecting rod 132 is loosened. At this time, the squeezing of the second spring 131 by the card plate 133 is reduced, and then the second spring 131 rebounds and causes the card plate 133 to move relative to each other until the two The clamping plate 133 contacts the magnetic core, thereby further limiting the magnetic core to prevent the magnetic core from shifting during the cutting process. After the magnetic core is fixed, the first motor 31 and the second motor 104 are started, thereby rotating the first shaft 5 and the second shaft 12, and then the first shaft 5 drives the screw rod 32 to rotate, and then the screw rod 32 drives the moving block 34 to move in the slide groove 4 during the rotation, and then the moving block 34 drives the connecting block 7 to move, and then the connecting block 7 pushes the magnetic core to move, and the second shaft 12 drives the first gear 107 and the first rotating roller 102 to rotate. Because the first gear 107 and the second gear 108 are engaged with multiple teeth of the synchronous belt 106, the second gear 108 rotates while the first gear 107 rotates, and then the second gear 108 drives the second rotating roller 103 to rotate, and then the cutting line 101 connected between the first rotating roller 102 and the second rotating roller 103 rotates to cut the moving magnetic core.
