Description

Technical Field

[0001] The utility model relates to the technical application field of automation equipment, and particularly relates to an appearance detection device for a motor stator. Background Art

[0002] The motor stator is an important component of motors such as generators and starters. The motor stator is an important part of the motor. The motor stator consists of three parts: a stator core, a stator winding, and a frame. The main function of the motor stator is to generate a rotating magnetic field, while the main function of the rotor is to be cut by magnetic lines of force in the rotating magnetic field to generate an output current.

[0003] During the traditional detection of the stator appearance, manual detection is used. When the number of stators to be detected is large, the existing detection devices have a low degree of automation, cannot meet the requirements of full-automatic testing, and have poor adaptability. Therefore, there is an urgent need to provide an appearance detection device for a motor stator. Summary of the Utility Model

[0004] To solve the above technical problems, the utility model provides an appearance detection device for a motor stator. The first downward press start of the servo motor can simultaneously complete the tests of the inner diameter, height, and flatness of the stator, improving the efficiency compared with manual testing and ensuring the accuracy.

[0005] The technical solution of the utility model is: an appearance detection device for a motor stator, including a frame, a measurement tooling arranged on the frame, and a test component arranged on the frame. The test component is slidably connected to the frame through a servo press and can move up and down along the height direction of the frame to test the stator placed on the measurement tooling;

[0006] The test component includes a test bracket detachably connected to the servo press. The test bracket is elastically provided with an inner diameter gauge. When the servo press drives the inner diameter gauge located on the test bracket to move towards the stator, the inner diameter gauge has two states relative to the stator:

[0007] The inner diameter gauge enters the stator, indicating that the inner diameter of the stator meets the standard;

[0008] The inner diameter gauge abuts against the upper end face of the stator, indicating that the inner diameter of the stator does not meet the standard.

[0009] Further, a gauge bracket is arranged inside the test bracket. The gauge bracket is connected to the inner diameter gauge through a telescopic rod. The telescopic rod extends the inner diameter gauge out of the test bracket, and a spring is sleeved at one end of the telescopic rod where the inner diameter gauge is located.

[0010] Further, the test bracket is provided with a top measurement sensor for cooperating with the telescopic rod.

[0011] Furthermore, the testing component further includes a pressing plate disposed at the bottom of the testing bracket through a sliding rod, and the pressing plate is provided with an opening for an internal diameter gauge to pass through. When the pressing plate abuts against the upper end face of the stator, it can move along the height direction of the sliding rod.

[0012] Furthermore, the outer diameter of the pressing plate is smaller than the outer diameter of the testing bracket, and a height measuring sensor is provided on one side of the testing bracket.

[0013] Furthermore, a fixing plate is further provided at the bottom of the testing bracket. The fixing plate is provided with a plurality of flatness detection sensors, and the pressing plate is provided with through holes for the flatness detection sensors to pass through.

[0014] Furthermore, a centering rod is provided at the bottom of the testing bracket, and the measuring tooling is provided with a centering hole for cooperating with the centering rod.

[0015] Furthermore, a plurality of support rods are further provided at the bottom of the testing bracket, and the plurality of support rods are located on both sides of the centering rod.

[0016] Furthermore, a fixing seat connected to the testing bracket is provided at the telescopic end of the servo press, and the fixing seat and the testing bracket are detachably connected by bolts.

[0017] Furthermore, an arc-shaped bracket is provided on one side of the testing bracket, and a guide rod for detachably inserting and cooperating with the arc-shaped bracket is provided on the frame.

[0018] The beneficial technical effects of the present utility model are as follows:

[0019] 1. The internal diameter of the stator is detected by an internal diameter gauge. At the same time, the internal diameter gauge is elastically arranged to avoid rigid contact between the internal diameter gauge and the end of the stator when the internal diameter of the stator is small, so as to protect the stator.

[0020] 2. Since the stator is composed of multiple layers of parts, the upper end face of the stator is pressed by the pressing plate so that the height measuring sensor can measure the height of the stator to ensure the testing accuracy.

[0021] 3. The pressing plate and the flatness detection sensor are used in cooperation to be able to test the flatness of the end face of the stator.

[0022] 4. The testing bracket and the fixing seat are detachably arranged, and through the settings of the guide rod, the arc-shaped bracket and the fixing seat, it is convenient to assemble and remove the testing component, so as to replace the adapted testing component according to different workpieces.

[0023] 5. The setting of the support rods facilitates the placement of the entire testing component and avoids damage to components such as the internal diameter gauge.

Detailed Description of the Preferred Embodiments

[0033] In order to be able to more clearly understand the technical means of the present invention and implement it in accordance with the content of the specification, the following further describes in detail the specific embodiments of the present invention with reference to the accompanying drawings and embodiments. The following embodiments are used to illustrate the present invention, but are not used to limit the scope of the present invention.

[0034] It should be noted that the terms "first", "second", etc. in the specification and claims of the present application and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged under appropriate circumstances so as to implement the embodiments of the present application described herein.

[0035] In the description of the present utility model, it should be noted that the orientation or positional relationship indicated by the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc. is based on the orientation or positional relationship described in the embodiments and shown in the drawings, or the orientation or positional relationship in which the utility model product is customarily placed during use. It is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present utility model.

[0036] As Figures 1 - 5 shown, the present utility model specifically relates to an appearance detection device for a motor stator, including a frame 420, a measuring tooling 410 provided on the frame 420, and a test assembly 440 provided on the frame 420. The test assembly 440 is slidably connected to the frame 420 through a servo press 430 and can move up and down along the height direction of the frame 420 to test the stator placed on the measuring tooling 410;

[0037] The test assembly 440 includes a test bracket 441 detachably connected to the servo press 430. The test bracket 441 is elastically provided with an internal diameter gauge 4423. When the servo press 430 drives the internal diameter gauge 4423 located on the test bracket 441 to move towards the stator, the internal diameter gauge 4423 has two states relative to the stator:

[0038] The internal diameter gauge 4423 enters the inside of the stator, indicating that the inner diameter of the stator meets the standard;

[0039] The internal diameter gauge 4423 abuts against the upper end face of the stator, indicating that the inner diameter of the stator does not meet the standard.

[0040] It should be noted that among them, the internal diameter gauge 4423 has a standard size and is used to detect the inner diameter of the stator. If the inner diameter of the stator meets the standard, then the internal diameter gauge 4423 can be placed inside the stator; if the inner diameter of the stator does not meet the standard, then the internal diameter gauge 4423 cannot be placed inside the stator.

[0041] When the stator is placed on the measuring tooling 410, the servo press 430 drives the internal diameter gauge 4423 to move vertically downward through the test bracket 441, so that the internal diameter gauge 4423 enters the inside of the stator to complete the detection of the inner diameter of the stator;

[0042] When the internal diameter gauge 4423 cannot enter the interior of the stator, the internal diameter gauge 4423 abuts against the upper end face of the stator. Since the internal diameter gauge 4423 is elastically connected to the test bracket 441, it is avoided that the internal diameter gauge 4423 makes rigid contact with the upper end face of the stator, thus avoiding damage to the stator. When the internal diameter gauge 4423 cannot enter the interior of the stator, the servo press 430 drives the internal diameter gauge 4423 to return to its initial position for rechecking the stator.

[0043] A gauge bracket 442 is provided inside the test bracket 441. The gauge bracket 442 is connected to the internal diameter gauge 4423 through a telescopic rod 4421. The telescopic rod 4421 extends the internal diameter gauge 4423 outside the test bracket 441, and a spring 4422 is sleeved on one end of the telescopic rod 4421 where the internal diameter gauge 4423 is located. The test bracket 441 is provided with a top measurement sensor 4424 for use in conjunction with the telescopic rod 4421.

[0044] If the internal diameter gauge 4423 can enter the interior of the stator, then the spring 4422 will not be compressed and the telescopic rod 4421 will not change. If the internal diameter gauge cannot enter the interior of the stator, then the spring 4422 will be in a compressed state, and accordingly the telescopic rod 4421 will also change. After the top measurement sensor 4424 detects a change in the telescopic rod 4421, the servo press 430 drives the internal diameter gauge 4423 to return to its initial position.

[0045] The test assembly 440 further includes a pressing plate 443 provided at the bottom of the test bracket 441 through a sliding rod 4431. The pressing plate 443 is provided with an opening 4433 for the internal diameter gauge 4423 to pass through. When the pressing plate 443 abuts against the upper end face of the stator, it can move along the height direction of the sliding rod 4431.

[0046] During the normal test process and when the internal diameter of the stator meets the standard, the position of the internal diameter gauge 4423 will not change. Since the pressing plate 443 is connected to the test bracket 441 through the sliding rod 4431, when the internal diameter gauge enters the interior of the stator, the pressing plate 443 abuts against the upper end face of the stator, and the pressing plate 443 moves relative to the internal diameter gauge 4423 through the sliding rod 4431, and the internal diameter gauge 4423 passes through the opening 4433 and enters the interior of the stator.

[0047] Meanwhile, during the process of the internal diameter gauge entering the interior of the stator, the pressing plate 443 continuously exerts pressure on the upper end face of the stator, and after the internal diameter enters the interior of the stator, the pressing plate 443 maintains the force exerted on the upper end face of the stator to ensure the theoretical flatness of the upper end face of the stator.

[0048] The outer diameter of the pressing plate 443 is smaller than the outer diameter of the test bracket 441. A height measurement sensor 4434 is provided on one side of the test bracket 441 to measure the height of the stator under the pressing state.

[0049] A fixing plate 444 is further provided at the bottom of the test bracket 441. The fixing plate 444 is provided with a plurality of flatness detection sensors 4441, and the pressing plate 443 is provided with a through hole 4432 for the flatness detection sensors 4441 to pass through.

[0050] As mentioned above, the pressing plate 443 moves relative to the internal diameter gauge 4423, further enabling the pressing plate 443 to abut against the fixing plate 444. The flatness detection sensors 4441 pass through the through holes 4432 to detect the flatness of the upper end face of the stator. If the flatness of the upper end face meets the requirements, the data of the plurality of flatness detection sensors 4441 should be consistent or have a small difference.

[0051] A centering rod 447 is provided at the bottom of the test bracket 441. The measuring tooling 410 is provided with a centering hole 411 for cooperating with the centering rod 447. The centering rod 447 is inserted into the centering hole 411, further ensuring the accuracy during the downward pressing process.

[0052] A plurality of support rods 445 are further provided at the bottom of the test bracket 441. The plurality of support rods 445 are located on both sides of the centering rod 447.

[0053] As mentioned above, the test assembly 440 is detachably connected to the servo press 430. After the test assembly 440 is disassembled, it is supported by the plurality of support rods 445 to prevent the internal diameter gauge 4423 from directly contacting the ground, etc.

[0054] A fixing seat connected to the test bracket 441 is provided at the telescopic end of the servo press 430. The fixing seat and the test bracket 441 are detachably connected by bolts, which is convenient for replacing the adapted test assembly 440 according to different workpieces.

[0055] There are various detachable methods. In this embodiment, bolt fixation is preferably used.

[0056] An arc-shaped bracket 446 is provided on one side of the test bracket 441. The frame 420 is detachably inserted into a guide rod 421 for cooperating with the arc-shaped bracket 446.

[0057] The servo press 430 drives the test assembly 440 to move downward to a specified position. At this time, the arc-shaped bracket 446 abuts against the guide rod 421. The operator disassembles the bolts between the test bracket 441 and the fixing seat. After the disassembly is completed, the operator pulls the test assembly 440 to move along the direction of the guide rod 421 to take out the test assembly 440.

[0058] The replacement of the test assembly 440 adopts the same operation method and will not be described in detail here.

[0059] The above embodiments are only specific implementation manners of the present utility model, used to illustrate the technical solutions of the present utility model, rather than limiting it. The protection scope of the present utility model is not limited thereto. Although the present utility model has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: Any person skilled in the art within the technical scope disclosed by the present utility model can still modify the technical solutions recorded in the foregoing embodiments, or can easily think of changes, or perform equivalent replacements on some of the technical features; and these modifications, changes or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present utility model, and should all be covered within the protection scope of the present utility model.
