Description

Technical Field

[0001] This utility model relates to the field of automation equipment technology, and specifically to an ejection device for iron core fixtures. Background Technology

[0002] In the manufacturing process of electronic components such as motors and transformers, the iron core typically needs to be positioned, inspected, or processed in a specialized fixture. After the process is completed, the iron core needs to be safely and efficiently removed from the fixture. Traditional removal methods often involve manual tapping, prying, or using simple ejector pins, which have the following obvious drawbacks: Inefficient: Manual operation is slow and cannot meet the cycle time requirements of automated production lines; Risk of damage: Improper force may scratch the surface of the iron core or damage the precision structure inside the fixture, resulting in product scrap and fixture repair; Poor safety: The operation may cause safety hazards such as pinching injuries to operators; Unable to handle fixtures with limiting structures: For some complex fixtures with built-in moving parts and limiting parts (used to firmly fix the iron core during processing), traditional methods cannot automatically remove these restrictions before ejection, resulting in difficult or impossible ejection. Utility Model Content

[0003] This utility model aims to at least partially solve one of the technical problems in related technologies. Therefore, one objective of this utility model is to provide an ejection device for an iron core fixture, comprising: a fixing frame, wherein a storage groove is provided in the middle of the fixing frame, and the storage groove is through-type; Two clamping mechanisms are provided on the fixed frame and respectively on both sides of the top of the storage slot. The two clamping mechanisms on the fixed frame can rotate to move closer or further away from each other to clamp the fixture containing the iron core. A pressing mechanism is provided on the fixed frame and spaced apart at the top of the storage slot and in the same vertical direction as the storage slot. The pressing mechanism can rise or fall in the vertical direction to push the iron core out of the fixture. Two unlocking mechanisms are respectively spaced apart on both sides of the pressing mechanism. The two unlocking mechanisms can rise or fall vertically. When the two unlocking mechanisms fall vertically, they push the movable parts on the outer periphery of the fixture to fall, so that the limiting parts inside the fixture used to restrict the iron core gradually move away from the iron core, so that the iron core can be pushed out of the fixture by the pressing mechanism.

[0004] Preferably, the fixing frame is provided with a shelf, and the shelf has a through groove in the middle. The through groove is provided along the thickness direction of the shelf and corresponds to the shelf groove.

[0005] Preferably, the clamping mechanism includes: a fixing block, which is disposed on the placement plate and on the side of the top of the through groove; A limiting plate is provided on the top of the fixing block and forms a sliding groove with the fixing block and the placement plate; A knob plunger is provided on the fixed block, with one end of the knob plunger located on the outer side of the fixed block and the other end located on the inner side of the fixed block.

[0006] Preferably, the fixing frame is further provided with a mounting bracket.

[0007] Preferably, the pressing mechanism includes: a support frame, which is vertically mounted on the mounting frame; A slide rail is mounted on the support frame and is arranged along the vertical direction of the support frame; A pneumatic rod, which is vertically mounted on the support frame and spaced apart from the slide rail; A skateboard, which is slidably mounted on the slide rail, and the transmission end of the gas spring is connected to the top of the skateboard; A fixing post is vertically installed at the bottom of the slide plate, and the fixing post and the storage slot are arranged in the same vertical direction.

[0008] Preferably, the cross-section of the skateboard is L-shaped.

[0009] Preferably, the unlocking mechanism includes a cylinder, with the cylinder rod vertically mounted on the mounting bracket; A connecting plate is disposed at the bottom of the cylinder and connected to the transmission end of the cylinder; A positioning post is provided at the end of the connecting plate and is arranged in an L-shape with the connecting plate.

[0010] The above-mentioned solution of this utility model has at least the following beneficial effects: by setting up an automatically lifting pressing mechanism and an unlocking mechanism, the core ejection process is automated, which greatly improves production efficiency and is easy to integrate into automated production lines. Through two rotatable clamping mechanisms, the fixture can be firmly clamped on the fixed frame before ejection, preventing it from moving or tilting during the ejection process, thus ensuring the accuracy and reliability of the ejection action. The device is equipped with unlocking mechanisms on both sides. Its working logic is that before the ejection mechanism is activated, the unlocking mechanism descends first, pushing the movable parts on the fixture to retract or move the internal limiting parts, thereby completely releasing the restraint on the iron core. This sequence ensures that the iron core is pushed out without resistance, fundamentally avoiding damage to the iron core and fixture caused by forced ejection.

[0021] The ejection device for iron core fixtures according to embodiments of the present invention will now be described in detail with reference to the accompanying drawings.

[0022] Please refer to Figures 1-3. In this embodiment, the fixture includes: a fixed frame 1 with a storage slot in the middle, the storage slot being through-hole; two clamping mechanisms 2, which are mounted on the fixed frame 1 and respectively located on both sides of the top of the storage slot, the two clamping mechanisms 2 being able to rotate relative to each other on the fixed frame 1 to clamp the fixture containing the iron core; a pressing mechanism 3, which is mounted on the fixed frame 1 and spaced apart on the top of the storage slot and in the same vertical direction as the storage slot, the pressing mechanism 3 being able to rise or fall vertically to push the iron core out of the fixture; and two unlocking mechanisms 4, which are spaced apart on both sides of the pressing mechanism 3, the two unlocking mechanisms 4 being able to rise or fall vertically. When the two unlocking mechanisms 4 fall vertically, they push the movable parts on the outer periphery of the fixture downwards, so that the limiting parts inside the fixture used to restrict the iron core gradually move away from the iron core, so that the iron core can be pushed out of the fixture by the pressing mechanism 3.

[0023] The fixture containing the iron core is placed in the storage slot of the fixed frame 1. The through-type design of the storage slot provides a channel for the downward ejection of the iron core. The two clamping mechanisms 2 on the fixed frame 1 are operated to rotate and move closer to each other, firmly clamping the fixture from both sides to ensure that the fixture remains fixed in subsequent operations. The two unlocking mechanisms 4 receive the action signal and descend synchronously in the vertical direction. The movement of the moving parts is transmitted through the internal structure of the fixture (such as connecting rods, inclined planes, etc.), driving the limiting parts (such as pawls, locking blocks, etc.) used to limit the position of the iron core to gradually move away from the iron core until they are completely disengaged, thereby releasing all the mechanisms on the iron core. Mechanical constraint; after the pressing mechanism 3 receives the ejection signal (which can be linked with the unlocking signal or slightly delayed), its driving component starts, pushing the entire pressing mechanism 3 down vertically; since the pressing mechanism 3 and the placement slot are in the same vertical direction, its end will accurately press on the upper surface of the unconstrained iron core; the pressing mechanism 3 continues to move downward, smoothly and steadily pushing the iron core out of the fixture cavity through the placement slot, completing the removal of the part; after ejection, the pressing mechanism 3 rises to reset, and then the unlocking mechanism 4 rises to reset (releasing the movable parts of the fixture, allowing them to return to their original state under the action of internal springs, etc.), and finally the clamping mechanism 2 rotates to release, so that the empty fixture can be taken out, ready for the next cycle.

[0024] In this embodiment, the fixing frame 1 is provided with a shelf 101, and a through groove 102 is provided in the middle of the shelf 101. The through groove 102 is provided through the thickness direction of the shelf 101 and corresponds to the shelf groove.

[0025] A shelf 101 is provided on the top of the fixed frame 1. The shelf 101 can be fastened to the fixed frame 1 with bolts to form a stable working platform. A through groove 102 is provided in the middle of the shelf 101. The through groove 102 completely penetrates the shelf body along the thickness direction of the shelf 101. The through groove 102 corresponds and aligns perfectly with the shelf groove in the middle of the fixed frame 1 in the vertical direction. When the jig containing the iron core is placed on the shelf 101, the bottom of the jig or the iron core to be ejected is exactly above the through groove 102. This ensures that when the pressing mechanism 3 performs the ejection action, its force can pass through the through groove 102 without obstruction and smoothly push the iron core into and through the shelf groove below, thereby completing the entire ejection process.

[0026] In this embodiment, the clamping mechanism 2 includes: a fixing block 201, which is disposed on the shelf 101 and on the side of the top of the through groove 102; a limiting plate 202, which is disposed on the top of the fixing block 201 and forms a sliding groove with the fixing block 201 and the shelf 101; and a knob plunger 203, which is disposed on the fixing block 201, with one end of the knob plunger 203 disposed on the outer side of the fixing block 201 and the other end disposed on the inner side of the fixing block 201.

[0027] The fixing block 201 can be fixedly installed on the shelf 101 by bolts and is located on the edge side of the top of the through groove 102. A limiting plate 202 is installed on the top of the fixing block 201. The limiting plate 202, together with the surface of the shelf 101 below and the inner side of the fixing block 201, forms a slide groove with an approximately "L" shaped cross section. The slide groove provides guidance and accommodation space for the side of the fixture. A knob plunger 203 is installed on the fixed block 201. The knob plunger 203 is screwed horizontally into a threaded hole pre-set on the side wall of the fixed block 201. Its front end can extend into the slide groove formed by the limiting plate 202, the fixed block 201 and the placement plate 101. When the operator pushes the fixture into place along the slide groove, the knob of the knob plunger 203 can be manually rotated to extend the plunger at the front end inward until it tightly abuts against the side of the fixture, thereby using friction to achieve reliable clamping and positioning of the fixture to be processed.

[0028] In this embodiment, the fixed frame 1 is also provided with a mounting frame 5; a mounting frame 5 is further fixedly installed on the top of the fixed frame 1. The mounting frame 5 serves as the upper support structure of the entire device. It is firmly connected to the fixed frame 1 below by means of columns or direct welding to form a stable rigid frame. The pressing mechanism 3 and the two unlocking mechanisms 4 are both directly or indirectly mounted on this mounting frame 5. Specifically, the mounting frame 5 provides a vertical mounting base and guide support for the pressing mechanism 3, and also provides a fixed mounting position and force fulcrum for the two unlocking mechanisms 4. By integrating these three core actuators onto a unified mounting frame 5, not only is their precise positional relationship relative to the storage slot on the fixed frame 1 ensured, but the entire ejection device structure is also more compact and rigid, ensuring stable and precise force transmission during ejection and unlocking operations.

[0029] In this embodiment, the pressing mechanism 3 includes: a support frame 301, which is vertically mounted on the mounting frame 5; a slide rail 302, which is mounted on the support frame 301 and arranged along the vertical direction of the support frame 301; and a pneumatic rod 303, which is vertically mounted on the support frame 301 and spaced apart from the slide rail 302. The slide plate 304 is slidably mounted on the slide rail 302, and the transmission end of the gas spring 303 is connected to the top of the slide plate 304; the fixing post 305 is vertically mounted on the bottom of the slide plate 304, and the fixing post 305 and the storage slot are mounted in the same vertical direction.

[0030] Near the slide rail 302, a pneumatic rod 303 is vertically mounted on the support frame 301, with its cylinder body fixedly connected to the support frame 301. A slide plate 304 with an approximately L-shaped cross section slides against the slide rail 302, allowing the slide plate 304 to move smoothly up and down along the slide rail 302. The top of the slide plate 304 is connected to the transmission end of the pneumatic rod 303, i.e., the end of its piston rod, so that the pneumatic rod 303 drives its lifting and lowering. At the bottom of the slide plate 304, a fixed column 305 is vertically installed. The position of the fixed column 305 is precisely set so that it is strictly aligned with the storage slot on the fixed frame 1 in the vertical direction. When the gas spring 303 drives the slide plate 304 to move downward, the fixed column 305 descends accordingly and passes through the top opening of the storage slot. Its bottom end acts on the iron core in the fixture, thereby performing the ejection action.

[0031] In this embodiment, the unlocking mechanism 4 includes: a cylinder 401, with a cylinder rod 303 vertically mounted on the mounting bracket 5; a connecting plate 402, which is located at the bottom of the cylinder 401 and connected to the transmission end of the cylinder 401; and a positioning post 403, which is located at the end of the connecting plate 402 and is L-shaped with the connecting plate 402.

[0032] Cylinder 401 is vertically fixed on the mounting bracket 5, with its cylinder body securely connected to the bracket 5. Connecting plate 402 is horizontally positioned below cylinder 401 and connected to the transmission end of cylinder 401, i.e., the end of its piston rod. When cylinder 401 actuates, it drives connecting plate 402 to move vertically up and down. A positioning post 403 is vertically mounted at the end of connecting plate 402. This positioning post 403 is perpendicular to the horizontally positioned connecting plate 402, forming a stable L-shaped structure. This L-shaped structure ensures that the positioning post 403 can move precisely downwards as the connecting plate 402 descends, allowing its bottom end to accurately act on the moving parts of the fixture's outer circumference, pushing it down to complete the unlocking action.
