Description

Technical Field

[0001] This invention relates to the field of stator performance testing technology, and more specifically, to a device for testing the energizing performance of a stator. Background Technology

[0002] The stator is the stationary part of an electric motor or generator. It consists of a frame, stator core, coils, and other structural components that fix these parts. The frame is used to fix the core; the core is part of the generator's magnetic circuit; and the coils form the generator's circuit. The main function of the stator is to generate a rotating magnetic field, which causes the rotor to be cut by magnetic lines of force in the rotating magnetic field, thereby generating or outputting current. After the stator is manufactured, its circuit conductivity needs to be tested to ensure that it can be used normally.

[0003] Currently, most motor stator windings use either a star or delta connection. In a star connection, the terminals of one winding are connected together, while the other three terminals of the coil winding are connected to a three-phase power supply. In a delta connection, the six wires of the three windings are connected end to end in a triangle, and the connection is connected to a three-phase power supply. Both of these connections require four wires to connect the stator windings and the power supply. The existing testing method for four-wire stators involves first connecting two wires of the same group, then connecting them to the input and output terminals of the testing instrument, and observing the changes in the indicator lights on the instrument to determine whether the test has passed. Existing stator testing devices cannot automatically connect the stator wiring to the testing area; manual straightening of the wires is required before connecting the four wires to the input and output terminals of the testing device for testing. This operation is cumbersome and highly dependent on manual labor. Summary of the Invention

[0004] To address the technical problems existing in the prior art, a stator energization performance testing device is provided.

[0005] The technical solution is as follows: A stator energization performance testing device includes a body, a testing mechanism for testing the energization performance of a stator, and a positioning component for guiding the stator wires to the testing mechanism; the testing mechanism includes a mounting frame that can slide on the body; a transformer detector installed at the bottom of the mounting frame for testing the energization performance of the stator wires after they are connected; two limiting posts that can slide horizontally on the mounting frame and are used in conjunction to limit the position of the stator; and a telescopic support rod that penetrates the body for supporting the stator to be tested; the positioning component includes a positioning slide that can slide vertically on the mounting frame, has a spring between it and the mounting frame, and has an oblong hole at the bottom; a positioning rod disposed on the positioning slide and on the same vertical line as the testing interface of the transformer detector; and a wire straightening slider that can slide within the oblong hole on the positioning slide and is used in conjunction with the positioning rod to straighten the stator wires and connect them to the transformer detector.

[0006] Preferably, the positioning rod expands outward at an angle greater than 45°; the end of the line-strapping slider that mates with the positioning rod is inclined in the opposite direction to the expansion direction of the positioning rod.

[0007] Preferably, the end of the line-straightening slider away from the positioning rod is chamfered; the contact position between the mounting bracket and the line-straightening slider is set as an inclined surface; the downward movement of the positioning slide will cause the chamfered part of the line-straightening slider to contact the inclined surface of the mounting bracket, forcing the line-straightening slider to move closer to the positioning rod; a spring is provided between the line-straightening slider and the positioning slide.

[0008] Preferably, a groove with a diameter matching the wire on the stator is formed at the contact point between the wire-straightening slider and the positioning rod, and the opening of the groove is set as an inclined surface opposite to the tilt direction of the wire-straightening slider.

[0009] Preferably, the machine body is provided with a wire-pulling assembly that can assist the stator wires to approach the positioning assembly. The wire-pulling assembly includes a folding rod with a horizontal bar portion extending out of the machine body; two wire-pulling slides that can slide on the machine body for moving the wires; and a dual-axis push block disposed on the vertical part of the folding rod and connected to the two wire-pulling slides.

[0010] Preferably, a spring is provided between the crossbar portion of the folding rod and the machine body; the end of the crossbar portion of the folding rod that extends out of the machine body contacts the top of the mounting frame; the maximum distance between the two cable guides is slightly less than the width of the mounting frame.

[0011] Preferably, the body is provided with a power assembly for pushing the mounting frame. The power assembly includes a cylinder I that provides power for pushing the mounting frame; and an annular pusher that can move synchronously with the movable end of the cylinder I, has its top connected to the mounting frame, and passes through the telescopic support rod.

[0012] Preferably, the machine body is further provided with a pull-down assembly, which includes a guide return frame disposed on the transverse portion of the machine body; a lifting rail that can slide on the guide return frame on the same side; and a triangular roller frame that can slide synchronously with the positioning slide, with the bottom rollers in contact with the lifting rail and capable of rolling on the lifting rail.

[0013] Preferably, the lifting track is divided into three parts: a high track, a low track, and an inclined track; the triangular roller frame is initially located in the high track section of the lifting track, and while it rolls along the inclined track towards the low track section, it can cause the positioning slide to descend.

[0014] Preferably, the machine body is provided with a separating component capable of pushing down the defective stator. The separating component includes a cylinder II that provides power for the sliding of the lifting rail; a double-axis rotating rod mounted on the output shaft of the cylinder II and with its two rotating shafts respectively connected to the lifting rail on the same side; and a sleeve rod sleeved on the limiting post and sliding out of the lifting rail.

[0015] The beneficial effects of the present invention are: 1. By setting up a detection mechanism and a positioning mechanism, after the stator is placed on the mounting frame, the positioning slide can be pulled down and slid down. Through the cooperation of the positioning rod and the wire straightening slider, the four wires on the stator can be straightened and contacted with each interface of the transformer detector at the same time, thereby quickly completing the wiring steps in the stator detection process. 2. By setting up the wire-pulling assembly, while the mounting frame slides, the spring between the bending rod and the machine body returns to its original tensioned state. Under the action of the dual-axis push block, the two wire-pulling slides move away from each other, and at the same time, the wires on the stator are pulled towards the positioning rod, and the auxiliary wires are connected to the transformer detector. 3. By setting up the power component and the pull-down component, the cylinder I and the ring pusher push the mounting frame to slide, while the triangular roller frame moves from the high rail part to the low rail part of the lifting track, and at the same time the positioning slide slides down, so that the connection of the stator wire can be completed without manual operation. 4. By setting up different components, when the stator fails the test, cylinder II and the double-axis rotating rod work together to push the two lifting tracks away from each other. At the same time, the two limit posts also move away from each other, and cylinder I is retracted, so that the defective stator falls directly into the collection box placed in advance on the left side of the machine body. For the finished products that pass the test, they can be removed and placed manually, thus realizing the distinction between finished products and defective products of the stator.

Detailed Implementation

[0028] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the present invention or its application or use. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0029] Example: A device for testing the energizing performance of a stator, such as... Figures 1-6 As shown, the device includes a body 1, a testing mechanism 2 for testing the electrical performance of the stator, and a positioning component 3 for guiding the stator wires to the testing mechanism 2. The testing mechanism 2 includes a mounting frame 23, which can slide on the body 1, and the top two corners of the U-shaped plate at its bottom are both set as inclined surfaces. A transformer detector 21 is mounted on the U-shaped plate at the bottom of the mounting frame 23 and can test the electrical performance of the stator. Two limiting posts 24 are provided, which can be positioned on the mounting frame 23. The stator can be restricted when the two limiting posts 24 are in contact with each other, and the telescopic support rod 22 is installed through the right support plate of the machine body 1 to support the stator to be tested; the positioning assembly 3 includes a positioning slide 31, which is symmetrically arranged on both sides of the mounting frame 23 and can slide vertically. It also has a waist-shaped hole 33 at its bottom and a spring between the positioning slide 31 and the mounting frame 23; the positioning rod 32 is symmetrically arranged at the bottom of the positioning slide 31 and is connected to the transformer. The detection interfaces of detector 21 are aligned vertically and expand outward at an angle greater than 45°, enabling them to guide and position the wire. The wire-straightening slider 34 slides within the oblong hole 33 on the positioning slide 31. The end of the wire-straightening slider 34 that mates with the positioning rod 32 is inclined in the opposite direction of the expansion of the positioning rod 32, forming a V-shape when they contact each other. The end of the wire-straightening slider 34 near the U-shaped plate on the mounting bracket 23 is chamfered and mates with it. As the positioning slide 31 slides down, the wire-straightening slider 34 will tilt... The corner contacts the inclined surface of the mounting bracket 23, forcing the wire straightening slider 34 to approach the positioning rod 32. A groove with an aperture matching the wire on the stator is opened at the contact point between the wire straightening slider 34 and the positioning rod 32. The opening of the groove is set as an inclined surface opposite to the tilt direction of the wire straightening slider 34, which can guide the wire into the groove. By cooperating with the positioning rod 32, the wire on the stator can be straightened and connected to the transformer detector 21 during the descent. A spring is provided between the wire straightening slider 34 and the positioning slide 31, which can reset the positioning slide 31 when it rises.

[0030] When inspecting the stator, the worker simply places the stator on the mounting frame 23, supports it with the telescopic support rod 22, and restricts its position with the limiting post 24. Then, the worker pulls the positioning slide 31 downward, causing the wire straightening slider 34 to contact the U-shaped plate at the bottom of the mounting frame 23 and slide within the waist-shaped hole 33 on the positioning slide 31 until it contacts the positioning rod 32. The positioning rod 32 and the wire straightening slider 34 together form a V-shape, which guides the wire and allows it to be inserted into the groove on the wire straightening slider 34. As the wire straightening slider 34 slides down with the positioning slide 31, it straightens the wire. When the positioning slide 31 reaches its lowest point, the wire connects to the interface of the transformer detector 21. By observing the transformer detector 21, the stator's power-carrying performance can be tested.

[0031] like Figure 1 , Figure 6 and Figure 7 As shown, the machine body 1 is equipped with a wire-pulling assembly 4 that assists the stator wires to approach the positioning assembly 3. The wire-pulling assembly 4 includes a folding rod 41, which is divided into a horizontal rod and a vertical rod. A spring is provided between the horizontal rod and the machine body 1, and the left end contacts the top of the mounting bracket 23. There are two sets of wire-pulling slides 43, which extend through the support plate on the right side of the machine body 1 and can slide on the machine body 1. They are used to pull the wires on the stator toward the positioning rod 32, and the maximum distance between the two wire-pulling slides 43 is slightly less than the width of the mounting bracket 23. There is also a double-axis push block 42, which is located at the bottom of the vertical rod of the folding rod 41. Its two rotating plates are respectively connected to the nearest wire-pulling slide 43.

[0032] After the stator is placed, push the mounting bracket 23 to the left so that the mounting bracket 23 no longer presses on the bending rod 41. The bending rod 41 will move to the left under the action of the spring. Under the action of the dual-axis push block 42, push the two wire-pulling slides 43 away from each other, and pull the wires on the stator to both sides so that the wires can complete the docking test more smoothly.

[0033] like Figure 1 and Figure 8 As shown, the body 1 is equipped with a power assembly 5 for pushing the mounting frame 23. The power assembly 5 includes a cylinder I 51, which provides power for pushing the mounting frame 23; and an annular pusher 52, which is installed on the movable end of the cylinder I 51 and can move synchronously with its movable end. The top of the annular pusher 52 is connected to the mounting frame 23. When it moves, it pushes the mounting frame 23 to slide on the body 1. The annular pusher 52 passes through the movable rod of the telescopic support rod 22 and can pull out the movable rod of the telescopic support rod 22. It can also support the stator when the mounting frame 23 moves.

[0034] like Figure 1 and Figure 9As shown, the machine body 1 is also equipped with a pull-down assembly 6, which includes a guide return frame 61. There are four guide return frames 61, with two symmetrically installed on each side of the transverse part of the machine body 1. A lifting rail 62 is installed on the guide return frame 61 on the same side and can slide on the guide return frame 61. The lifting rail 62 is divided into three parts: a high rail, a low rail, and an inclined rail. A triangular roller frame 63 is provided with rollers at the bottom of the triangular roller frame 63 and slides in contact with the bottom of the lifting rail 62. The triangular roller frame 63 is initially located at the high rail part of the lifting rail 62, and while it rolls along the inclined rail to the low rail part, it can cause the positioning slide 31 to descend. When the cylinder I 51 pushes the mounting frame 23 to move to the left, the triangular roller frame 63 slides along the lifting rail 62 and gradually descends, while simultaneously driving the positioning slides 31 on both sides of the machine body 1 to descend at the same time, without the need for manual pulling.

[0035] like Figure 1 and Figure 10 As shown, the machine body 1 is equipped with a separating component 7 that can push down the defective stator. The separating component 7 includes a cylinder II 71, which provides power for the sliding of the lifting rail 62 on the guide return frame 61; a double-axis rotating rod 72, which is mounted on the output shaft of the cylinder II 71, and its two rotating shafts are respectively connected to the lifting rail 62 on the same side. When the output shaft of the cylinder II 71 extends upward, it will cause the two rotating shafts of the double-axis rotating rod 72 to expand outward, pushing the lifting rail 62 away from each other; and a sleeve rod 73, the right end of which is connected to the limiting post 24. The left end slides out of the lifting track 62; when the stator fails the test, the cylinder II 71 is activated to move the two lifting tracks 62 away from each other. At the same time, the two limit posts 24 will also move away from each other under the action of the sleeve rod 73, and will no longer limit the stator. When the mounting frame 23 is pulled back by the cylinder I 51, the stator will fall directly after losing support. The worker needs to place a collection device on the left side of the machine body 1 in advance to collect the unqualified stator. For the stator that passes the test, there is no need to activate the cylinder II 71. After pulling it back by the cylinder I 51, it can be taken out normally.

Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters in the following figures denote similar items; therefore, once an item is defined in one figure, it need not be further discussed in subsequent figures.

[0038] In the description of this invention, it should be understood that the orientation or positional relationship indicated by directional terms such as "front, back, up, down, left, right", "horizontal, vertical, horizontal" and "top, bottom" is generally based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing this invention and simplifying the description.
