Description

Technical Field

[0001] This utility model belongs to the field of stator core technology, and in particular relates to a stacking fixture for exciter stator cores. Background Technology

[0002] The stator core is an important component that forms the magnetic flux circuit of the motor and fixes the stator coil. It is composed of laminations and various fasteners pressed together to form a whole.

[0003] A search revealed that Chinese Patent Publication No. CN221009966U discloses a stacking fixture for stator core production, comprising a fixture body and a protective mechanism disposed on the outer wall of the fixture body. The protective mechanism includes a fixing component; the fixing component includes a sliding rod, a sliding groove, and a fixed protective block. When processing stator cores using the stacking fixture, in order to improve the verticality of the stator core during stacking and prevent the stator core from shifting during stacking, thus affecting the stacking effect, a knob can be rotated to drive the threaded rod to slide along the inner wall of the fixed groove. The sliding of the threaded rod, connected by a rotating rod, drives the sliding rod to slide along the inner wall of the sliding groove. The sliding of the sliding rod causes the fixed protective block to clamp and protect the stator core, thereby improving the flatness of the stator core during stacking processing.

[0004] The above-mentioned patent has the following problems when used:

[0005] 1. Several stacked plates are clamped by two fixed protective blocks, but after stacking, the two fixed protective blocks need to be removed before material can be picked up, resulting in low material picking efficiency. Utility Model Content

[0006] The purpose of this invention is to provide a stacking fixture for exciter stator cores, which has the advantage of automatic unloading, in order to solve the technical problems mentioned in the background art.

[0007] To achieve the above objectives, the specific technical solution of this utility model is as follows: A stacking fixture for exciter stator cores includes a table panel, a material feeding slot is provided through the top of the table panel, and a stacking fixture is provided at the bottom of the table panel corresponding to the material feeding slot.

[0008] The stacking fixture includes a stacking clamping groove welded to the bottom of the table panel and corresponding to the material feeding slot. Limiting grooves are formed on both sides of the stacking clamping groove. Limiting sliders are slidably installed inside each of the two limiting grooves. A support plate is welded between the two limiting sliders and inside the stacking clamping groove. The tops of the two limiting sliders are mounted to the table panel via return springs. A connecting sleeve is welded to the bottom of the support plate. Clamping plate sleeves are welded through both ends of the connecting sleeve. Clamping plates are inserted through the interiors of both clamping plate sleeves. The ends of the two clamping plates that are far apart from each other are connected to the corresponding clamping plate sleeves via sleeved springs. A locking block at the top of a telescopic rod is inserted inside the connecting sleeve and at the top of the two clamping plates. An electric cylinder is inserted at the bottom of the telescopic rod.

[0009] As a preferred embodiment of this invention, both ends of the electric cylinder are mounted on both sides of the stacking clamping groove via fixing brackets.

[0010] As a preferred embodiment of the present invention, a feeding structure is provided on the top of the table panel and at the front end of the feeding slot, and a stacking and pressing structure is provided on the top of the table panel and corresponding to the feeding slot.

[0011] As a preferred embodiment of the present invention, the feeding structure includes a feeding chute opened at the front end of the feeding chute, a push plate is slidably installed inside the feeding chute, a lead screw is inserted into one end of the push plate away from the feeding chute, and the other end of the lead screw extends through the feeding chute and is fixedly installed with a rotating handle.

[0012] As a preferred embodiment of this utility model, both ends of the push plate are welded with limiting sliders, and the ends of the two limiting sliders that are far apart from each other are slidably installed on the limiting grooves that are correspondingly opened on both sides of the feed chute.

[0013] As a preferred embodiment of this utility model, the stacking and pressing structure includes a frame welded to the top of the table panel, a hydraulic cylinder fixedly installed on the top of the frame, and the bottom end of the hydraulic cylinder extending through the frame via an inserted hydraulic rod, and a pressing plate fixedly installed thereon.

[0014] As a preferred embodiment of this utility model, the bottom four corners of the tabletop are each fitted with support legs by welding.

[0015] As a preferred embodiment of this invention, the inside of the feeding trough is horizontally arranged with a stack of exciter stator core plates.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0017] 1. This is a stacking fixture for exciter stator cores. By moving the support plate down to its limit position, the upward pulling force of the two return springs exceeds the clamping force of the two spring-controlled clamping plates on the block. Subsequently, the support plate disengages from the connection between the electric cylinder and the telescopic rod, thereby lifting the stacked exciter stator core plate out of the discharge slot for easy material handling.

[0018] 2. This is a stacking fixture for exciter stator cores. By placing the exciter stator core stacking plate inside the feeding chute, rotating the control screw, and controlling the push plate to slide along the two limit chute 2 until the exciter stator core stacking plate is pushed into the discharge chute, the problem of being injured by the pressing plate is avoided when feeding by hand.

[0024] To further understand the invention content, features and effects of this utility model, the following embodiments are provided, and detailed descriptions are given in conjunction with the accompanying drawings.

[0025] The structure of this utility model will now be described in detail with reference to the accompanying drawings.

[0026] like Figures 1 to 4As shown, the present invention provides a stacking fixture for exciter stator cores, including a table panel 1, a material feeding slot 2 through the top of the table panel 1, and a stacking fixture 3 at the bottom of the table panel 1 corresponding to the material feeding slot 2.

[0027] The stacking fixture 3 includes a stacking clamping groove 301 welded to the bottom of the table panel 1 and corresponding to the material feeding slot 2. Limiting grooves 302 are provided on both sides of the stacking clamping groove 301. Limiting sliders 303 are slidably installed inside each of the two limiting grooves 302. A support plate 304 is welded between the two limiting sliders 303 and inside the stacking clamping groove 301. The tops of the two limiting sliders 303 are mounted to the table panel 1 via return springs 305. The bottom of the support plate 304... A docking sleeve 306 is welded on, and clamping sleeves 307 are welded through both ends of the docking sleeve 306. Clamping plates 308 are inserted through the interior of both clamping sleeves 307. The ends of the two clamping plates 308 that are far apart from each other are connected to the corresponding clamping sleeves 307 by sleeved springs 309. A locking block 3010 at the top of the telescopic rod 3011 is inserted inside the docking sleeve 306 and at the top of the two clamping plates 308. An electric cylinder 3012 is inserted at the bottom end of the telescopic rod 3011.

[0028] refer to Figure 2 and Figure 4 Both ends of the electric cylinder 3012 are mounted on both sides of the stacking clamping groove 301 via fixing brackets 3013.

[0029] The above solution involves mounting both ends of the electric cylinder 3012 on both sides of the stacking clamping groove 301 using fixing brackets 3013. This allows the electric cylinder 3012 to be fixed in place using two fixing brackets 3013, ensuring that the electric cylinder 3012 can output support capacity stably and avoiding tilting or misalignment.

[0030] refer to Figure 1 , Figure 2 and Figure 3A feeding structure 4 is provided on the top of the table panel 1 and at the front end of the feeding slot 2. A pressing structure 5 is provided on the top of the table panel 1 and corresponding to the feeding slot 2. The feeding structure 4 includes a feeding chute 401 opened at the front end of the feeding slot 2. A push plate 402 is slidably installed inside the feeding chute 401. A lead screw 403 is inserted into one end of the push plate 402 away from the feeding slot 2. The other end of the lead screw 403 extends through the feeding slot 2 and is fixedly installed with a rotating handle 404. Both ends of the push plate 402 are welded with limit sliders 405. The ends of the two limit sliders 405 that are far apart from each other are slidably installed on the limit grooves 406 that are opened on both sides of the feed chute 401. The stacking and pressing structure 5 includes a frame 501 welded to the top of the table panel 1. A hydraulic cylinder 502 is fixedly installed on the top of the frame 501. The bottom end of the hydraulic cylinder 502 extends through the frame 501 through the inserted hydraulic rod 503 and is fixedly installed with a pressing plate 504.

[0031] The above solution involves a feeding structure 4 located at the top of the platform 1 and at the front end of the feeding slot 2, and a stacking and pressing structure 5 located at the top of the platform 1 and corresponding to the feeding slot 2. The feeding structure 4 includes a feeding chute 401 at the front end of the feeding slot 2. A push plate 402 is slidably installed inside the feeding chute 401. A lead screw 403 is inserted into one end of the push plate 402 away from the feeding slot 2, and the other end of the lead screw 403 extends through the feeding slot 2 and is fixedly installed with a rotating handle 404. This facilitates placing the exciter stator core stack 7 inside the feeding chute 401. Rotating the rotating handle 404 controls the lead screw 403 to rotate, thereby controlling the push plate 402 to slide along the two limiting chute 406 until the exciter stator core stack 7 is pushed into the feeding slot 2. This avoids manual feeding, which could cause the pressed plate 5 to be pressed. To address the issue of impact damage, limit sliders 405 are welded to both ends of the push plate 402. The ends of the two limit sliders 405 that are far apart from each other are slidably installed on the corresponding limit grooves 406 on both sides of the feed chute 401. This achieves flexible and stable displacement by utilizing the directional sliding behavior between the two limit grooves 406 and the two limit sliders 405, avoiding jamming and misalignment. The stacking and pressing structure 5 includes a frame 501 welded to the top of the table panel 1. A hydraulic cylinder 502 is fixedly installed on the top of the frame 501. The bottom end of the hydraulic cylinder 502 extends through the frame 501 via a hydraulic rod 503 and is fixedly installed with a pressing plate 504. This allows the hydraulic cylinder 502 to control the pressing plate 504 at the bottom of the hydraulic rod 503 to move downward and press the exciter stator core stack 7, thus achieving the smooth implementation of the stacking behavior.

[0032] refer to Figure 1 , Figure 2 Support legs 6 are welded to the four corners of the bottom of the platform 1, and exciter stator core stack 7 is horizontally placed inside the material feeding slot 2.

[0033] The above solution is adopted: support legs 6 are welded to the four corners of the bottom of the table panel 1 to achieve stable support. The exciter stator core stack plate 7 is horizontally placed inside the material feeding slot 2 to achieve mechanized feeding and avoid the accident of the pressing plate 504 injuring the user's hand.

[0034] The working principle of this utility model:

[0035] In use, the exciter stator core stack 7 is placed inside the feed chute 401. Rotating the rotary handle 404 controls the lead screw 403 to rotate, causing the push plate 402 to slide along the two limit chute 406 until the exciter stator core stack 7 is pushed into the discharge chute 2. The hydraulic cylinder 502 controls the hydraulic rod 503 to extend and retract, controlling the pressing plate 504 to press the exciter stator core stack 7. The electric cylinder 3012 controls the support plate on the telescopic rod 3011. The 304 is displaced to the position where the top of the exciter stator core stack 7 is horizontal to the bottom of the feeding chute 401. When the two return springs 305 reach their limit positions, the upward pulling force of the two return springs 305 exceeds the clamping force of the clamping plate 308 on the block 3010 controlled by the two springs 309. Then the support plate 304 disengages from the connection between the electric cylinder 3012 and the telescopic rod 3011, thereby lifting the stacked exciter stator core stack 7 out of the discharge slot 2 for easy material handling.

[0036] In summary, this stacking fixture for exciter stator cores, by moving the support plate 304 to its limit position, causes the upward pulling force of the two return springs 305 to exceed the clamping force of the clamping plate 308 on the locking block 3010 controlled by the two springs 309. Subsequently, the support plate 304 disengages from the connection between the electric cylinder 3012 and the telescopic rod 3011, thereby lifting the stacked exciter stator core stack 7 out of the discharge slot 2. This facilitates material retrieval and solves the problem of low material retrieval efficiency caused by the need to remove two fixed protective blocks after stacking.
