Description

Technical Field

[0001] This utility model relates to the field of inductor coil processing technology, and more specifically, it relates to a positioning and clamping device for processing inductor products. Background Technology

[0002] Inductors are components that convert electrical energy into magnetic energy and store it. They operate based on the principle of electromagnetic induction and consist of an iron core and a coil wound around it. Before winding, the surface of the iron core needs to be coated with insulating varnish to prevent leakage.

[0003] Currently, the clamping device of spraying equipment on the market usually consists of two opposing clamping plates. The two clamping plates clamp the workpiece along the axial direction of the iron core before spraying. The clamping plates form a certain coverage area on the iron core. In order to ensure the comprehensiveness of the spraying, multiple clamping is usually required, which increases the processing difficulty and affects the processing efficiency. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a positioning and clamping device for processing inductor products that is easy to process.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A positioning and clamping device for processing inductor products includes a housing, the housing having a cylindrical structure, a bushing threadedly connected to the housing, a push block threadedly connected to the bushing, one end of the bushing extending out of the housing, and a plurality of grippers rotatably connected to the end of the bushing extending out of the housing, the plurality of grippers being able to jointly clamp an iron core, a motor installed inside the housing, the output end of the motor being slidably connected to the push block, a pressing surface being provided at the end of the push block opposite to the motor, one end of each gripper extending into the bushing, and the end of the gripper extending into the bushing abutting against the pressing surface.

[0007] The present invention is further configured such that: the gripper includes a connecting rod, the middle position of the connecting rod is rotatably connected to the bushing, one end of the connecting rod extends into the bushing and abuts against the extrusion surface, the other end of the connecting rod extends out of the bushing and is connected to an extrusion block, the extrusion block extends radially away from the axis of the bushing, and the extrusion block can abut against the inner wall of the iron core.

[0008] The present invention is further configured such that: the bushing is cylindrical, the outer wall of the bushing is provided with an external thread, the inner wall of the bushing is provided with an internal thread, a movable sleeve is fixed inside the outer shell, the external thread is threadedly connected to the movable sleeve, the push block is threadedly connected to the internal thread, the external thread is a coarse thread, the internal thread is a fine thread, the bottom of the bushing is provided with an end face, and the push block can abut against the end face.

[0009] The present invention is further configured such that: a drive shaft is connected to the output shaft of the motor, the drive shaft passes through the center of the push block, a connecting key is provided between the drive shaft and the push block, and the push block is slidably connected to the connecting key.

[0010] The present invention is further configured such that: the top of the outer shell is provided with a placement surface, the placement surface is used to place the iron core, and the bushing can extend out of the placement surface.

[0011] The advantages of this utility model are:

[0012] The iron core is placed on the placement surface, and the motor can drive the push block to move upward. The pressing surface drives the connecting rod to rotate until the pressing block abuts against the inner wall of the iron core. When the motor continues to rotate, the push block does not move. At this time, the torque is transmitted to the bushing, and the bushing rotates and moves upward on the moving sleeve, so that the iron core is lifted off the placement surface. This reduces the coverage area of ​​the fixture on the iron core, facilitates the spraying process, and reduces the number of clamping operations during the processing. Attached Figure Description

[0020] Please see Figure 1-3 The present invention provides the following technical solution:

[0021] A positioning and clamping device for processing inductor products includes a housing 1, which has a cylindrical structure. A bushing 2 is threadedly connected to the housing 1, and a push block 3 is threadedly connected to the bushing 2. One end of the bushing 2 extends out of the housing 1, and a plurality of grippers 5 are rotatably connected to the end of the bushing 2 extending out of the housing 1. The plurality of grippers 5 can jointly clamp an iron core. A motor 4 is installed inside the housing 1, and the output end of the motor 4 is slidably connected to the push block 3. A pressing surface 31 is provided at the end of the push block 3 away from the motor 4. One end of the gripper 5 extends into the bushing 2, and the end of the gripper 5 extending into the bushing 2 abuts against the pressing surface 31. A placement surface 12 is provided at the top of the housing 1 for placing the iron core. The bushing 2 can extend out of the placement surface 12.

[0022] The gripper 5 includes a connecting rod 51, which is rotatably connected to the bushing 2 at its middle position. One end of the connecting rod 51 extends into the bushing 2 and abuts against the pressing surface 31. The other end of the connecting rod 51 extends out of the bushing 2 and is connected to a pressing block 52. The pressing block 52 extends radially away from the axis of the bushing 2 and abuts against the inner wall of the iron core. When the push block 3 moves upward, the pressing surface 31 drives the connecting rod 51 to rotate outward until the pressing block 52 abuts against the inner wall of the iron core. At this time, the connecting rod 51 stops rotating and the push block 3 stops moving upward, thus achieving the clamping of the iron core.

[0023] The bushing 2 is cylindrical. The outer wall of the bushing 2 is provided with an external thread 22, and the inner wall of the bushing 2 is provided with an internal thread 23. The movable sleeve 11 is fixed inside the outer shell 1. The external thread 22 is threadedly connected to the movable sleeve 11, and the push block 3 is threadedly connected to the internal thread 23. The bottom of the bushing 2 is provided with an end face 21, and the push block 3 can abut against the end face 21.

[0024] The external thread 22 is a coarse thread, and the internal thread 23 is a fine thread. That is, when the push block 3 rotates, the friction on the internal thread 23 is small, and the internal thread 23 rotates first. That is, the push block 3 and the bushing 2 move relative to each other first. When the push block 3 stops moving, the torque on the push block 3 is transmitted to the bushing 2, causing the bushing 2 to rotate and move upward.

[0025] That is, the gripper 5 first clamps the iron core, and then the iron core is lifted off the placement surface 12 as the bushing 2 moves upward, which reduces the area covered by the fixture on the iron core and improves the processing efficiency.

[0026] A drive shaft 41 is connected to the output shaft of motor 4. The drive shaft 41 passes through the center of push block 3. A connecting key 42 is provided between drive shaft 41 and push block 3. Push block 3 and connecting key 42 are slidably connected.

[0027] Specifically, the iron core is placed on the placement surface 12, and the motor 4 can drive the push block 3 to move upward. The connecting rod 51 is driven to rotate through the pressing surface 31 until the pressing block 52 abuts against the inner wall of the iron core. When the motor 4 continues to rotate, the push block 3 does not move. At this time, the torque is transmitted to the bushing 2, and the bushing 2 rotates and moves upward on the moving sleeve 11, so that the iron core is lifted off the placement surface 12. This reduces the coverage of the fixture on the iron core, facilitates the spraying process, and reduces the number of clamping operations during the processing.

[0028] When the motor 4 rotates in the reverse direction, the push block 3 moves downward first, the gripper 5 retracts, and the iron core falls off until the push block 3 returns to its original position and abuts against the end face 21. At this time, the bushing 2 continues to move downward and return to its original position, and the iron core can be removed.
