Description

Technical Field

[0001] The utility model relates to the technical field of inductor pin cutting, and more particularly to an inductor pin cutting tool. Background Art

[0002] An inductor typically consists of a bobbin, a coil, and a mounting plate. The bobbin and mounting plate are connected, with the coil wrapped around the bobbin. Four pins extend from the coil, each extending through and securely attached to the mounting plate. The pins vary in length and require cutting using a cutting device. Existing cutting equipment requires the inductor to be secured using a cutting tool while the cutting device is in operation. When the existing pin-cutting tool is clamping and fixing the inductor, it is not easy to limit the position of the inductor, resulting in that the pin-cutting device may not be able to align the pins of the inductor, making it difficult to perform the pin-cutting operation; in addition, when the existing pin-cutting tool is clamping the inductor, the inductor is generally placed horizontally, that is, the pins are facing the horizontal direction, and then the mounting plate is clamped and fixed by the pin-cutting tool, but the skeleton and the coil have a heavy weight. Under the action of their own gravity, a large overturning moment will be caused to the connection between the pin-cutting tool and the mounting plate, shortening the service life of the pin-cutting tool, and under the action of their own weight, the clamping force of the skeleton and the coil may be too small, causing them to deviate downward, which will eventually cause the pin-cutting device to be unable to align the pins.

[0029] In this embodiment, the inductor includes a skeleton 26, a connecting plate 27 and a pin 28. When clamping the inductor, the worker holds the skeleton 26, fits the connecting plate 27 against the positioning device, positions it through the positioning device, and clamps it through the clamping device. At this time, the worker holds both sides of the skeleton 26 and starts the first cylinder 3 to drive the lifting plate 4 to move upward along the first guide rod 6, and then drives the third support frame 21 and the support seat 5 to move upward together. When the support seat 5 moves to fit with the skeleton 26, the first cylinder 3 continues to extend, and the spring 23 contracts, applying an extrusion force to the support seat 5 until the spring 23 is compressed to a certain extent. At this time, the first cylinder 3 stops extending, and the skeleton 26 is supported by the spring 23 and the support seat 5 to prevent it from applying a large overturning moment to the clamping device.

[0030] More specifically, the inductor includes a skeleton 26, a connecting plate 27 and pins 28. When clamping the inductor, the worker holds the skeleton 26, fits the connecting plate 27 against the positioning device, positions it through the positioning device, and then clamps it and fixes it through the clamping device. When the clamping device is clamping and fixing, the clamping plate 9 is first driven by the transverse movement mechanism to move to the corresponding clamping seat 10 and the connecting plate 27. At this time, the second cylinder 8 is started to shrink, driving the clamping plate 9 and the clamping seat 10 close to the connecting plate 27 until the clamping seat 10 presses the connecting plate 27 against the positioning plate 12, completing the clamping and fixation of the connecting plate 27.

[0031] See also Figure 1 、 Figure 2 and Figure 5 As an embodiment of the positioning device: the positioning device includes a fixing plate 11, a positioning plate 12, and an L-shaped limiting strip 13. The fixing plate 11 is arranged on the upper surface of the workbench 1. The positioning plate 12 and the fixing plate 11 are detachably connected by bolts. The L-shaped limiting strip 13 is fixedly arranged on one side of the fixing plate 11. Both the positioning plate 12 and the fixing plate 11 are provided with through holes 14. The L-shaped limiting strip 13 is provided with a groove 25 that cooperates with the clamping plate 9.

[0032] Specifically, when positioning the inductor, the worker holds the skeleton 26, fits the connecting plate 27 to the positioning plate 12, and passes the pin 28 through the through hole 14. The worker moves the skeleton 26 and fits the two side edges of the connecting plate 27 to the inner side of the L-shaped limit strip 13, and positions the connecting plate 27 through the L-shaped limit strip 13.

[0033] See also Figure 1-3 As a further implementation of the transverse movement mechanism: the transverse movement mechanism includes a second support frame 15, a mounting plate 16 and a third cylinder 17. The second support frame 15 is connected to the fixed plate 11, and the mounting plate 16 is fixedly set on the second support frame 15. The third cylinder 17 is connected to the mounting plate 16, and its telescopic end passes through the mounting plate 16 and is connected to the movable frame 7. The movable frame 7 is slidably set on the upper surface of the second support frame 15.

[0034] Specifically, the inductor includes a skeleton 26, a connecting plate 27 and a pin 28. When clamping the inductor, the worker holds the skeleton 26, fits the connecting plate 27 against the positioning device, positions it through the positioning device, and then clamps it and fixes it through the clamping device. When the clamping device is clamping and fixing, the third cylinder 17 is first started to extend it and drive the movable frame 7 to move on the second support frame 15 until the clamping plate 9 and the connecting plate 27 correspond. At this time, the connecting plate 27 is clamped and fixed by the clamping mechanism.

[0035] See also Figure 1-3As a further implementation of the adjustment mechanism: the adjustment mechanism includes a screw 19 and an adjusting knob 20, one end of the screw 19 is fixedly connected to the adjusting knob 20, and the other end passes through the clamping plate 9 and is fixedly connected to the clamping seat 10, and the screw 19 and the clamping plate 9 are threadedly connected.

[0036] Specifically, when dealing with connecting plates 27 of different thicknesses, the adjusting knob 20 can be rotated to drive the screw 19 to rotate, thereby driving the clamping seat 10 to approach the clamping plate 9 or away from the clamping plate 9. When the connecting plate 27 is thinner, the clamping seat 10 is away from the clamping plate 9. When the connecting plate 27 is thicker, the clamping seat 10 is close to the clamping plate 9. Therefore, when the thickness of the connecting plate 27 is different and the telescopic length of the second cylinder 8 does not change accordingly, the position of the clamping seat 10 can be adjusted to adapt to connecting plates 27 of various thicknesses.

[0037] In summary, when the overall equipment is in use:

[0038] After clamping the inductor, the worker holds both sides of the skeleton 26 and starts the first cylinder 3, so that it drives the lifting plate 4 to move upward along the first guide rod 6, and then drives the third support frame 21 and the support seat 5 to move upward together. When the support seat 5 moves to fit with the skeleton 26, the first cylinder 3 continues to extend and the spring 23 contracts, applying an extrusion force to the support seat 5 until the spring 23 is compressed to a certain extent. At this time, the first cylinder 3 stops extending and supports the skeleton 26 through the spring 23 and the support seat 5 to prevent it from applying a large overturning moment to the clamping device.

[0039] When positioning the inductor, the worker holds the skeleton 26, fits the connecting plate 27 against the positioning plate 12, and passes the pin 28 through the through hole 14. The worker moves the skeleton 26 and fits the two side edges of the connecting plate 27 against the inner side of the L-shaped limit strip 13, and positions the connecting plate 27 through the L-shaped limit strip 13.

[0040] When clamping the inductor, the worker holds the skeleton 26, fits the connecting plate 27 against the positioning device, positions it through the positioning device, and then clamps it and fixes it through the clamping device. When the clamping device is clamping and fixing, the third cylinder 17 is first started to extend and drive the movable frame 7 to move on the second support frame 15 until the clamping plate 9 and the connecting plate 27 correspond, and the second cylinder 8 is started to contract and drive the clamping plate 9 and the clamping seat 10 to approach the connecting plate 27 until the clamping seat 10 presses the connecting plate 27 against the positioning plate 12, completing the clamping and fixing of the connecting plate 27; when the thickness of the connecting plate 27 changes, the adjusting knob 20 is turned to drive the screw 19 to rotate, thereby driving the clamping seat 10 to approach the clamping plate 9 or away from the clamping plate 9. When the thickness of the connecting plate 27 is thinner, the clamping seat 10 is away from the clamping plate 9, and when the thickness of the connecting plate 27 is thicker, the clamping seat 10 is close to the clamping plate 9.

[0041] In all the schemes mentioned above, the connection between the two components can be selected according to actual conditions by welding, bolt and nut connection, bolt or screw connection or other well-known connection methods, which will not be listed here one by one. In the above, all fixed connections are preferably welded. Although the embodiments of the present invention have been shown and described, it can be understood by ordinary technicians in this field that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention.
