Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of motor core testing devices, and in particular to a device for testing the penetration performance of oil holes in motor cores. Background Technology
[0002] With the continuous development of automotive automation, the efficiency and accuracy of manual inspection of corresponding components on automobiles can no longer meet the growing demands of automated production lines. For example, in the motors used in automobiles, the continuity of oil holes in the motor core needs to be inspected, but manual inspection cannot meet the required accuracy and repeatability, resulting in low inspection efficiency.
[0003] In the prior art, such as the iron core oil hole penetration detection device and its control method with application number 202511092124.1, a high-precision oil hole penetration detection process is formed by sensor detection and algorithm judgment. The principle is as follows: the infrared detection device is not blocked, the lifting component continues to move, the mounting plate is attached to the base plate under the action of the baffle of the detection mechanism, and the detection rod on the base plate passes through the through hole into the oil hole of the iron core. If the iron core oil hole is blocked, the detection rod lifts the iron core and blocks the signal of the infrared detection device, thus completing the automatic detection of the iron core. It does not require complex image processing. However, it is not completely applicable to some motor iron cores where the oil holes are not vertical, that is, the holes on the upper and lower end faces of the motor iron core are not on the same diameter circle; and the image detection method is also not applicable. Utility Model Content

[0022] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.
[0023] like Figures 1 to 5 As shown, a device for testing the penetration performance of oil holes in a motor core includes... The system comprises a machine base 11, a translation mechanism 20, a pressing mechanism 30, a containment mechanism 40, and a detection mechanism. The translation mechanism 20 includes a horizontal drive assembly 21 and a support plate 22 for supporting the motor core, located at the output end of the horizontal drive assembly 21. The support plate 22 has multiple first air holes 220. The pressing mechanism 30 includes a lifting drive assembly 31 and a cover plate 32 located at the output end of the lifting drive assembly 31. The cover plate 32 is located above the end of the horizontal drive assembly 21 and has multiple second air holes (not shown). The cover plate 32 is driven to move downward and abut against the upper end of the motor core. The containment mechanism 40 includes multiple... The enclosure unit 400 is located beside the end of the horizontal drive assembly 21. The enclosure unit 400 includes a drive member 41 and an enclosure plate 42 disposed at the output end of the drive member 41. The enclosure plate 42 is provided with multiple air intake channels 420. The multiple enclosure plates 42 are driven to abut against each other and against the side wall of the motor core. The upper end and lower end of the enclosure plate 42 abut against the cover plate 32 and the support plate 22, respectively. The detection mechanism includes an air supply component (not shown) and a detection component 51. The air supply component is connected to the air intake channel 420 through an air intake duct assembly. The detection component 51 is connected to the first air hole 220 and the second air hole through an air outlet duct assembly.
[0024] Combination Figure 6As shown, the motor core 100 has multiple oil holes. Specifically, the vertical slit 101 located on the side wall of the motor core 100, the upper hole 102 connected to the vertical slit 101 at the upper end, and the lower hole (not shown) connected to the vertical slit 101 at the lower end form an oil hole. When applying this utility model, the motor core 100 is placed on the support plate 22, and the position of the motor core 100 is adjusted so that its lower hole corresponds to the first air hole 220 on the support plate 22. The motor core 100 is driven by the horizontal drive assembly 21 to move below the pressure plate 32. The pressure plate 32 is driven by the lifting drive assembly 31 to move down and abut against the upper end of the motor core 100, and the second air hole on the pressure plate 32 corresponds to the upper hole 102 of the motor core 100. Multiple enclosure units 400 are activated, that is, the drive member 41 (optionally a cylinder) drives the enclosure plate 42 to move closer to the motor core 100. After the enclosure plate 42 moves a certain distance, multiple enclosure units 400 are activated. The sidewalls of the plates 42 abut against each other, and the sidewall of the plate 42 abuts against the sidewall of the motor core 100, so that the end of the air intake channel 420 is connected to the vertical slit 101 on the sidewall of the motor core 100. The upper and lower ends of the plate 42 abut against the pressure plate 32 and the bearing plate 22 respectively to seal the upper and lower ends of the plate 42. When the air supply component 50 delivers gas, the gas is delivered to the air intake channel 420 through the air intake duct assembly and delivered to the vertical slit 101. The gas can flow along the direction of the vertical slit 101 and to the first air hole 220 and the second air hole, and then enter the detection component 51 through the air outlet duct assembly to detect the size of the airflow. Specifically, the air intake... The conduit assembly includes an intake manifold and multiple intake branch pipes. The intake manifold is connected to the multiple intake branch pipes via solenoid valves. The multiple intake branch pipes are connected to multiple intake channels 420 respectively. The exhaust conduit assembly includes two exhaust manifolds and multiple exhaust branch pipes. The multiple exhaust branch pipes are connected to a first air port 220 and a second air port respectively. The exhaust branch pipe connected to the first air port 220 is connected to a detection component 51 via a solenoid valve. The exhaust branch pipe connected to the second air port is connected to another detection component 51 via another solenoid valve. The detection component 51 can be a gas flow meter. When performing oil hole penetration testing, the solenoid valve at the intake end controls the intake manifold to connect to the second air port. One intake branch pipe is connected, which delivers gas to the intake channel 420. Since the end of the intake channel 420 is connected to a vertical slit 101, and since the enclosure plate 42 abuts against the side wall of the motor core 100, the gas in the intake channel 420 can only enter the vertical slit 101. The gas flows downward and upward in the vertical slit 101 and enters the lower hole and upper hole 102 connected to the vertical slit 101, respectively, and then enters the exhaust branch pipe connected to the lower hole and upper hole 102, respectively. Similarly, during the intake process, the exhaust branch pipe is connected to the exhaust main pipe through the action of a solenoid valve. The gas enters the detection component 51 through the exhaust main pipe to detect the flow rate.For example, when the oil hole is open, a pair of detection components 51 detect flow data, and the flow data matches the flow data of the air supply component. When the oil hole is not open, one of the detection components 51 has no flow data or the data is abnormal, thus completing the openness test of one oil hole. Furthermore, by controlling the solenoid valve to connect different intake manifolds and intake branch pipes, as well as exhaust manifolds and exhaust branch pipes, the openness test of different oil holes can be achieved separately.
[0025] This invention tests the permeability of oil holes by using air intake and exhaust methods and by measuring gas flow rate. It is more suitable for testing motor cores where the oil holes are not vertically positioned.
[0026] Preferably, the enclosure 42 includes an outer plate 421 and an inner plate 422. The outer plate 421 is disposed at the output end of the drive member 41 and has multiple air inlets 4210. The air inlets 4210 are connected to the air supply member through an air inlet duct assembly. The inner plate 422 has multiple horizontally arranged air inlet slits 4220 penetrating its body. The inner plate 422 is disposed on the outer plate 421. The air inlet slits 4220 and the air inlets 4210 are connected to form an air inlet channel 420. The air inlet slits 4220 are horizontally arranged and have a certain width (matching the width of the vertical slit 101), which can achieve similar air outlet speed and air volume at different positions, allowing the gas to quickly enter the vertical slit 101 in a horizontally spread manner. It should be noted that the multiple air inlet slits 4220 on an inner plate 422 are not connected.
[0027] Furthermore, the end of the air intake channel 420 (i.e. the end of the air intake slit 4220) is located in the middle of the motor core 100. The air intake slit 4220 is opposite to the middle of the vertical slit 101, so that after the gas enters the vertical slit 101, it can flow out through the upper hole 102 and the lower hole respectively. On the one hand, this ensures the uniformity of airflow, and on the other hand, the flow rate data can be used to roughly determine the permeability of the corresponding position (the upper or lower part of the vertical slit 101) in the oil hole.
[0028] Preferably, the inner plate 422 is in an interference fit with the cover plate 32 and the bearing plate 22, the inner plates 422 are in an interference fit with each other, and the inner plate 422 is in an interference fit with the side wall of the motor core 100. This can ensure the sealing of the enclosure plate 42 after it comes into contact with each component, and ensure airtightness.
[0029] The horizontal drive assembly 21 includes a rodless cylinder 211 and a slide plate 212. The slide plate 212 is slidably mounted on the machine base 11 via a guide rail pair 213 and is located at the output end of the rodless cylinder 211, which enables the bearing plate 22 to drive the motor core 100 to move smoothly and accurately.
[0030] Furthermore, a central positioning post 221 is provided on the support plate 22. The motor core 100 is sleeved on the central positioning post 221 and positioned on the support plate 22, which can ensure its stability and make the lower hole on the motor core 100 opposite to the first air hole 220 on the support plate 22.
[0031] The lifting drive assembly 31 includes a bracket 300 and a lifting cylinder 31. The lifting cylinder 31 is mounted on the bracket 300 and has a mounting plate 311 at its lower end. A cover plate 32 is mounted at the lower end of the mounting plate 311. The mounting plate 311 is mounted on the support column 301 of the bracket 300 by sliding up and down through the guide cylinder 302, which can ensure the accuracy of the up and down movement of the cover plate 32 so that its second air hole can be aligned with the upper hole 102 of the motor core 100.
[0032] Furthermore, the lower end of the cover plate 32 is provided with at least two positioning inserts 33. By inserting the positioning inserts 33 into the side seam of the inner wall of the motor core 100, the motor core 100 can be prevented from rotating relative to the support plate 22, ensuring that the upper hole 102 and the lower hole of the motor core 100 are accurately aligned with the second air hole on the cover plate 32 and the first air hole 220 on the support plate 22, respectively.
[0033] In addition, safety light curtains 60 are provided on opposite sides of the housing 12 on the machine base 11 to ensure operational safety.
[0034] The specific embodiments described herein are merely illustrative examples illustrating the spirit of this utility model. Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to substitute them, without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.
