Description

Technical Field

[0001] This utility model relates to the field of pneumatic detection technology, specifically a pneumatic detection device. Background Technology

[0002] The motor end cap is one of the key components of an electric motor, and its dimensional accuracy directly affects the overall performance of the motor. The end cap needs to accurately support the rotor and ensure the uniformity of the air gap between the rotor and the stator, which is crucial for the stable operation of the motor. If the dimensional accuracy of the end cap does not meet the standards, it may lead to uneven air gap, which in turn affects the efficiency, noise, and vibration levels of the motor.

[0003] When performing precision testing on traditional motor end caps, a micrometer is typically used for manual inspection. However, because the micrometer is relatively hard, it can cause bumps and scratches to the object being inspected during the inspection, affecting the processing quality and resulting in defective products. Therefore, there is an urgent need for an inspection device that will not damage the object being inspected during the inspection process. Utility Model Content

[0004] To address the problem that existing micrometers easily scratch the object being tested, this invention provides a pneumatic testing device.

[0005] The present invention discloses a pneumatic detection device comprising: a support component and a detection component; the support component includes a support member and a limiting member, the limiting member being connected to one side of the support member and having at least one detection head; and the detection component includes a detection member and an air supply pipe, at least one of the detection members being disposed on one side of the limiting member, one end of the air supply pipe being connected to the detection member, and the other end of the air supply pipe being connected to the limiting member and communicating with the detection head.

[0006] Preferably, the number of detection heads, detection components, and gas supply pipes are the same, and one detection component corresponds to one detection head.

[0007] Preferably, a pneumatic detection device further includes a pressure application component, which includes a mounting plate, a pressure application element, and an elastic element. The mounting plate is disposed on one side of the limiting element, and the pressure application element is disposed between the limiting element and the mounting plate. One end of the pressure application element is connected to the mounting plate, and the other end of the pressure application element is connected to the pressure application element.

[0008] Preferably, the pressure application assembly further includes a screw member, one end of which is connected to the bearing member, and the screw member penetrates the mounting plate.

[0009] Preferably, the screw component has threads on its surface, and the portion of the mounting plate through which the screw component penetrates has a matching threaded groove.

[0010] Preferably, the pressure application component further includes a buffer, and the side of the pressure application component near the limiting member is connected to the buffer.

[0011] Preferably, the buffer is made of a flexible material.

[0012] Preferably, the pressure application component further includes a guide member, one end of which is connected to the pressure application component, and the guide member extends through the mounting plate.

[0013] Preferably, there are two guide members, which are respectively connected to both sides of one side of the pressure member.

[0014] Compared with the prior art, the present invention provides a pneumatic detection device with the following advantages:

[0015] 1. This pneumatic detection device, by setting up a support component and a detection component, allows the object to be detected to be placed on the limiting component and the detection head to be in close contact with the object. Then, with the cooperation of the detection component and the air supply pipe, the detection head blows out gas. Under the obstruction of the object to be detected, the air pressure inside the detection head increases. The electrical converter in the detection component converts the pressure on the detection head into an electrical signal and displays the detection data, thereby completing the pneumatic detection of the object to be detected. This avoids the situation where the object to be detected is easily scratched when using a micrometer.

[0016] 2. This pneumatic detection device, by setting up a pressure application component, enables the pressure application component to be pushed by the elastic element under the action of the mounting plate when the object to be detected is being detected. This pushes the object to be detected closer to the detection head and ensures that the object to be detected is in close contact with the detection head, thereby ensuring the accuracy of the pneumatic detection device during detection.

[0017] 3. This pneumatic detection device, by setting a screw component inside the pressure application assembly, and the mounting plate being able to be adjusted along the screw component to move away from or closer to the limiting component, allows for adjustment of the distance between the pressure application component and the limiting component. This ensures that the pressure application assembly can apply pressure to objects of any size to be tested, thereby improving the detection capability of the pneumatic detection device.

[0025] The embodiments of this disclosure will now be described in detail with reference to the accompanying drawings.

[0026] The following specific examples illustrate the implementation of this disclosure. Those skilled in the art can easily understand other advantages and effects of this disclosure from the content disclosed in this specification. Obviously, the described embodiments are only a part of the embodiments of this disclosure, and not all of them. This disclosure can also be implemented or applied through other different specific embodiments, and the details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of this disclosure. It should be noted that, in the absence of conflict, the following embodiments and features in the embodiments can be combined with each other. Based on the embodiments in this disclosure, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this disclosure.

[0027] Reference Figures 1-3 , Figure 1 This is a schematic diagram of the structure of this utility model; Figure 2 This is another structural schematic diagram of the present invention; Figure 3 This utility model Figure 1 Enlarged schematic diagram of the structure at point A. A pneumatic detection device includes: a support component 1 and a detection component 2. The support component 1 includes a support member 11 and a limiting member 12. The limiting member 12 is connected to one side of the support member 11 and has at least one detection head 121. The detection component 2 includes a detection member 21 and an air supply pipe 22. At least one detection member 21 is disposed on one side of the limiting member 12. One end of the air supply pipe 22 is connected to the detection member 21, and the other end of the air supply pipe 22 is connected to the limiting member 12 and communicates with the detection head 121.

[0028] Specifically, the detection component 21 is equipped with an electrical converter for detecting the pressure on the detection head 121 and a display screen for displaying the detection data.

[0029] This pneumatic detection device, by setting up a support component 1 and a detection component 2, allows the object to be detected to be placed on the limiting component 12 and the detection head to be in close contact with the object. Then, with the cooperation of the detection component 21 and the air supply pipe 22, the detection head 121 blows out gas. Under the obstruction of the object to be detected, the air pressure inside the detection head 121 increases. The electrical converter in the detection component 21 converts the pressure on the detection head 121 into an electrical signal and displays the detection data, thereby completing the pneumatic detection of the object to be detected. This avoids the situation where the object to be detected is easily scratched when using a micrometer.

[0030] The number of detection heads 121, detection elements 21 and air supply pipes 22 are the same, and one detection element 21 corresponds to one detection head 121, so that each detection element 21 can be detected by one detection head 121, thereby detecting the data of this part.

[0031] Specifically, there are multiple detection heads 121, which can detect multiple parts of the object to be detected.

[0032] A pneumatic detection device further includes a pressure application component 3, which includes a mounting plate 31, a pressure application component 33, and an elastic component 34. The mounting plate 31 is disposed on one side of the limiting component 12, the pressure application component 33 is disposed between the limiting component 12 and the mounting plate 31, one end of the 34 is connected to the mounting plate 31, and the other end of the 34 is connected to the pressure application component 33.

[0033] The pneumatic detection device, by setting up a pressure application component 3, enables the pressure application component 33 to be pushed by the elastic element 34 under the action of the mounting plate 31 when the object to be detected is being detected. This pushes the object to be detected closer to the detection head 121 and ensures that the object to be detected is in close contact with the detection head 121, thereby ensuring the accuracy of the pneumatic detection device when it is being detected.

[0034] The pressure application assembly 3 also includes a screw member 32, one end of which is connected to the bearing member 11, and the screw member 32 penetrates the mounting plate 31.

[0035] Specifically, the screw 32 has threads on its surface, and the part of the mounting plate 31 through which the screw 32 passes has a matching threaded groove, so that the mounting plate 31 can be adjusted to move away from or closer to the limiting member 12 by rotating the screw 32.

[0036] The pneumatic detection device has a screw 32 installed inside the pressure application assembly 3, and the mounting plate 31 can be adjusted along the screw 32 to move away from or closer to the limit member 12. This allows the distance between the pressure application assembly 33 and the limit member 12 to be adjusted, thereby ensuring that the pressure application assembly 3 can apply pressure to objects of any size to be tested, thus improving the detection capability of the pneumatic detection device.

[0037] The pressure application assembly 3 also includes a buffer 35. The side of the pressure application assembly 33 near the limiting member 12 is connected to the buffer 35, and the buffer 35 is made of a flexible material, so that when pressure is applied to the object to be tested by the pressure application assembly 3, the buffer 35 can contact the object to be tested, avoiding damage caused by rigid contact.

[0038] The pressure application assembly 3 also includes a guide 36. One end of the guide 36 is connected to the pressure application assembly 33, and the guide 36 passes through the mounting plate 31. This allows the pressure application assembly 33 to be guided by the guide 36 when it approaches or moves away from the limiting member 12 under the action of the 34, thereby ensuring that pressure can be applied stably to the object to be tested and that the object to be tested will not deviate.

[0039] There are two guide members 36, which are connected to both sides of one side of the pressure member 33, respectively, to further improve the stability of the movement of the pressure member 33.
