Description

Technical Field

[0001] This disclosure relates to the field of parts inspection technology, and in particular to an actuator inspection device. Background Technology

[0002] In air conditioning systems, actuators are often required to be connected to the housing. For example, a damper actuator is connected inside the housing. For ease of assembly, the damper actuator has three connection holes on its outer periphery. The relative positional relationship of these three connection holes needs to meet theoretical requirements to ensure successful damper actuator assembly. Therefore, it is necessary to test the relative positional relationship of the three connection holes in the actuator.

[0003] In related technologies, when checking whether the connection holes of the actuator meet the requirements, professionals generally use a coordinate measuring machine to perform high-precision measurements on the geometric dimensions, shape, and positional tolerances of each connection hole in the actuator.

[0004] However, the above testing process is relatively complex because it requires professionals to operate the corresponding coordinate measuring machine, and the coordinate measuring machine used is also very expensive, making it inconvenient for widespread application. Utility Model Content

[0005] This disclosure provides a testing device for actuators, which can simplify the testing process for connecting holes in actuators and reduce testing costs. The technical solution is as follows:

[0006] This disclosure provides a detection device for an actuator, which is used to detect the positional relationship of multiple connecting holes in the actuator. The detection device includes a detection base plate, multiple support columns, and multiple detection pins. The multiple support columns and multiple detection pins are spaced apart from each other on the same surface of the detection base plate. The axes of the multiple support columns are parallel to the surface of the base plate, and the center lines of the multiple support columns are located on at least two planes. One end of each support column is connected to the detection base plate, and the other end of the multiple support columns is located on a first plane for supporting the actuator. The multiple detection pins are arranged one-to-one with the multiple connecting holes, and the distance between two adjacent detection pins is the same as the theoretical distance between two adjacent connecting holes. The axis of each detection pin is parallel to the axis of the support column. One end of the detection pin is connected to the detection base plate, and the other end is coaxially located in the corresponding connecting hole.

[0007] In another implementation of this disclosure, the detection pin includes a connecting section and a mating section along its own axial direction. One end of the connecting section is connected to the detection substrate, and the other end of the connecting section is connected to one end of the mating section. The outer diameter of the connecting section is not less than the outer diameter of the mating section.

[0008] In another implementation of this disclosure, the height of the support column is the same as the height of the connecting segment.

[0009] In another implementation of this disclosure, the plurality of detection pins includes a first detection pin, a second detection pin, and a third detection pin, wherein the cross-sections of the first detection pin and the second detection pin away from the top of the detection substrate are both circular, and the cross-section of the third detection pin away from the top of the detection substrate is oval.

[0010] In another implementation of this disclosure, the detection device further includes a positioning pin, which is located on the same surface as the detection substrate. One end of the positioning pin is connected to the detection substrate, and the other end of the positioning pin is used to insert into the pin hole of the actuator.

[0011] In another implementation of this disclosure, the positioning pin is located between one of the detection pins and one of the support columns.

[0012] In another implementation of this disclosure, the height of the positioning pin is greater than the height of the support column and less than the height of the detection pin.

[0013] In another implementation of this disclosure, the detection substrate includes a flat plate and two side panels, the two side panels being located on the same surface of the flat plate and on opposite sides of the flat plate; each of the side panels is connected to the flat plate, and the flat plate and the two side panels define a U-shaped space for arranging the detection pin and the support column.

[0014] In another implementation of this disclosure, each of the side panels has a cavity in the middle that extends through opposite sides of the side panel, and the cavities of the two side panels are arranged opposite each other along the arrangement direction of the two side panels.

[0015] In another implementation of this disclosure, the plate has a plurality of through holes arranged at intervals along the outer periphery of the plate.

[0016] The beneficial effects of the technical solutions provided in this disclosure are:

[0017] When the detection device provided in this embodiment detects the three connection holes in an actuator, since the detection device includes a detection base plate, multiple support columns, and multiple detection pins, the detection base plate can provide a mounting foundation for the support columns and detection pins. Simultaneously, since the other ends of the multiple support columns are located on a first plane for supporting the actuator, the actuator can be supported by the support columns during detection, ensuring it is positioned on the first plane and preventing inaccurate detection results due to actuator tilting. Furthermore, since the multiple detection pins are arranged one-to-one with the multiple connection holes, and the distance between two adjacent detection pins is the same as the theoretical distance between two adjacent connection holes, with one end of the detection pin connected to the detection base plate and the other end coaxially located in the corresponding connection hole, during detection, when the actuator is placed on the support columns, the connection holes in the actuator can be fitted one-to-one with the detection pins. By observing the fit between each detection pin and its corresponding connection hole, it can be determined whether the positional relationship of the connection holes meets the requirements. If a detection pin cannot pass smoothly through the corresponding connection hole, it indicates that the positional relationship of the connection holes does not meet the requirements. If the test pin can pass smoothly through the corresponding connection hole, it means that the positional relationship of the connection hole meets the requirements. Attached Figure Description

[0029] To make the objectives, technical solutions, and advantages of this disclosure clearer, the embodiments of this disclosure will be described in further detail below with reference to the accompanying drawings.

[0030] Figure 1 This is a structural diagram of the damper actuator in a certain air conditioner. Figure 1 This actuator is used to adjust the opening and closing angle or position of a damper (air valve), thereby controlling the direction, airflow, or temperature of the air conditioning system. The actuator has three connection holes 101 on its outer periphery, arranged in a triangular pattern. Furthermore, of the three connection holes 101, the first connection hole 101 is a cylindrical hole, the second connection hole 101 is a horizontal hole... Figure 1 The waist-shaped hole extends in the left and right directions, and the third connecting hole 101 is along the... Figure 1 An oblong hole extending vertically. One end of each of the three connecting holes 101 is located on the first side of the actuator.

[0031] To ensure that the positional relationship between the three connecting holes meets the assembly requirements, it is necessary to inspect them. Therefore, this disclosure provides an actuator inspection device for detecting the positional relationship of the three connecting holes in the actuator.

[0032] Figure 2 This is a schematic diagram of the structure of a detection device for an actuator provided in an embodiment of this disclosure, as shown below. Figure 2 As shown, the detection device includes a detection substrate 1, multiple support columns 2 and multiple detection pins 3.

[0033] Multiple support pillars 2 and multiple detection pins 3 are spaced apart from each other on the same plate surface of the detection substrate 1. The axes of the multiple support pillars 2 are parallel to the plate surface, and the center lines of the multiple support pillars 2 are located on at least two planes.

[0034] Figure 3 for Figure 2 The front view, combined with Figure 3 One end of each of the multiple support columns 2 is connected to the detection base plate 1, and the other end of each of the multiple support columns 2 is located on the first plane used to support the actuator. Figure 3 On the plane indicated by the dashed line a.

[0035] Multiple detection pins 3 are arranged in a one-to-one correspondence with multiple connecting holes, and the distance between two adjacent detection pins 3 is the same as the theoretical distance between two adjacent connecting holes. The axis of each detection pin 3 is parallel to the axis of the support column 2. One end of the detection pin 3 is connected to the detection substrate 1, and the other end is coaxially located in the corresponding connecting hole.

[0036] When the detection device provided in this embodiment detects the three connection holes in the actuator, since the detection device includes a detection base plate 1, multiple support columns 2, and multiple detection pins 3, the detection base plate 1 can provide a mounting foundation for the support columns 2 and detection pins 3. Simultaneously, since the other ends of the multiple support columns 2 are located on a first plane for supporting the actuator, during detection, the actuator can be lifted by the support columns 2 to ensure it is positioned on the first plane, preventing inaccurate detection results due to actuator tilting. Furthermore, since the multiple detection pins 3 are arranged one-to-one with the multiple connection holes, and the distance between two adjacent detection pins 3 is the same as the theoretical distance between two adjacent connection holes, with one end of each detection pin 3 connected to the detection base plate 1 and the other end coaxially located in the corresponding connection hole, during detection, when the actuator is placed on the support columns 2, the connection holes in the actuator can be fitted one-to-one with the detection pins 3. By observing the fit between each detection pin 3 and the corresponding connection hole, it can be determined whether the positional relationship of the connection holes meets the requirements. If the detection pin 3 cannot pass smoothly through the corresponding connection hole, it indicates that the positional relationship of the connection holes does not meet the requirements. When the detection pin 3 can pass smoothly through the corresponding connecting hole, it means that the positional relationship of the connecting holes meets the requirements.

[0037] In this embodiment, the distance between the two detection pins 3 refers to the distance between the axes of the two detection pins 3. The distance between two adjacent connecting holes refers to the distance between the centers of the two connecting holes.

[0038] See also Figure 3 Optionally, the detection pin 3 includes a connecting section 31 and a mating section 32 along its own axis. One end of the connecting section 31 is connected to the detection substrate 1, and the other end of the connecting section 31 is connected to one end of the mating section 32. The outer diameter of the connecting section 31 is not less than the outer diameter of the mating section 32, and the mating section 32 is used to be coaxial with the corresponding connecting hole.

[0039] In the above implementation, the connecting section 31 connects the detection pin 3 to the detection substrate 1, and the mating section 32 extends into the corresponding connecting hole of the detection pin 3 to mate with the corresponding connecting hole. Thus, during detection, the mating relationship between the mating section 32 and the corresponding connecting hole can be directly observed to determine whether the positional relationship of the connecting holes meets the requirements.

[0040] Optionally, the height of the support column 2 is the same as the height of the connecting section 31.

[0041] In the above implementation, since one end of each of the three connecting holes in the actuator is located on the first side of the actuator, when the height of the support column 2 is set to be the same as the height of the connecting section 31, during the detection, when the first side of the actuator facing the detection device is fitted onto the corresponding detection pin 3, the first side of the actuator will naturally fit with each support column 2, and one end of the connecting hole will be limited and flush with the end face connected to the connecting section 31 and the mating section 32, thereby detecting whether the connecting holes are located on the same plane through the connecting section 31.

[0042] Optionally, the detection pin 3 also includes a guide section 33, one end of which is connected to the end of the mating section 32 away from the connecting section 31, and the outer diameter of the guide section 33 is not greater than the outer diameter of the mating section 32.

[0043] In the above implementation, the guide segment 33 is used to pass through the corresponding connection hole so that the actuator will not arbitrarily detach from the detection device during detection.

[0044] For example, the connecting section 31, the mating section 32, and the guide section 33 are all cylindrical structures with a tapered surface at the end away from the detection substrate 1. The maximum outer diameter of the guide section 33 is smaller than the minimum outer diameter of the mating section 32, and the maximum outer diameter of the mating section 32 is smaller than the minimum outer diameter of the connecting section 31. This arrangement not only facilitates their interconnection but also allows the connecting hole to pass through.

[0045] In addition, in order to facilitate the mating of the detection pin 3 with the corresponding positioning hole, the cross-sectional shape of the guide section 33 and the mating section 32 of the detection pin 3 can be the same as the shape of the corresponding connecting hole.

[0046] For example, in this embodiment, the plurality of detection pins 3 include a first detection pin, a second detection pin, and a third detection pin. The top cross-sections of the first and second detection pins away from the detection substrate 1 are both circular, and the top cross-section of the third detection pin away from the detection substrate 1 is oval.

[0047] Optionally, the detection substrate 1, the detection pin 3, and the support column 2 are integrated into a single structural component.

[0048] This allows for rapid processing of the testing device, improving production efficiency.

[0049] In this embodiment, the detection substrate 1, the detection pin 3, and the support column 2 are all aluminum structural components.

[0050] By using aluminum structural components, the detection device can be made lighter, and the aluminum structural components can automatically form an oxide film on their surface to protect the detection device, prevent rust, and extend its service life.

[0051] In this embodiment, to increase the space of the support column 2, each support column 2 includes a first segment 21, a second segment 22, a third segment 23, and a fourth segment 24 connected in sequence. The bottom of the first segment 21 is connected to the detection substrate 1, and the top of the fourth segment 24 is used to support the actuator.

[0052] The first segment 21 and the third segment 23 are both cylindrical structures of equal diameter, with the outer diameter of the first segment 21 being larger than that of the third segment 23. The second segment 22 is a tapered segment, with the outer diameter of its small end being the same as that of the third segment 23, and the outer diameter of its large end being the same as that of the first segment 21. The fourth segment 24 is also a tapered segment, designed to prevent scratches on the actuator during placement due to its smooth curved surface.

[0053] See you again Figure 2 Optionally, the detection device also includes a positioning pin 4, which is located on the same plate surface as the detection base plate 1. One end of the positioning pin 4 is connected to the detection base plate 1, and the other end of the positioning pin 4 is used to insert into the pin hole of the actuator.

[0054] For ease of positioning, the top cross-section of the positioning pin 4 is the same shape as the pin hole.

[0055] In the above implementation, the positioning pin 4 facilitates the positioning of the actuator during testing, enabling the actuator to be quickly assembled into the testing device.

[0056] Optionally, the locating pin 4 is located between one of the detection pins 3 and one of the support columns 2.

[0057] In the above implementation, the positioning pin 4 can be inserted only into the middle of the actuator, rather than the edge, when it is engaged with the pin hole of the actuator, so as to improve the positioning effect.

[0058] Optionally, the height of the locating pin 4 is greater than the height of the support column 2 and less than the height of the detection pin 3.

[0059] In the above implementation, the height of the positioning pin 4 is set above the structure, which can ensure that the positioning pin 4 can be inserted into the pin hole, while the positioning pin 4 will not affect the arrangement of the actuator due to being too long.

[0060] Optionally, the detection substrate 1 includes a flat plate 11 and two side panels 12, which are located on the same surface of the flat plate 11 and on opposite sides of the flat plate 11.

[0061] Each side panel 12 is connected to a flat plate 11, and the flat plate 11 and the two side panels 12 define a U-shaped space for arranging the detection pin 3 and the support column 2.

[0062] In the above implementation, the plate 11 is used to provide an installation base for the detection pin 3 and the support column 2, etc., and the side panel 12 is used to define a U-shaped space with the plate 11 in order to protect the actuator, etc.

[0063] Figure 4 for Figure 3 The side view, combined with Figure 4 Optionally, the middle part of the side wall 12 has a cavity 120 that passes through the opposite sides of the side wall 12, and the cavities 120 of the two side walls 12 are arranged opposite each other along the arrangement direction of the two side walls 12.

[0064] In the above implementation, the arrangement of cavities not only reduces the weight of the detection device, but also makes it easier to hold and place the detection device.

[0065] Optionally, the side enclosure 12 is a trapezoidal fence, including a top plate 121 and two oppositely arranged side plates 122. The top plate 121 is opposite to and spaced apart from the flat plate 11. The two side plates 122 are located between the top plate 121 and the flat plate 11, and each side plate 122 is connected to the flat plate 11 and the top plate 121 respectively.

[0066] In the above implementation, the side plate 122 is used to connect the top plate 121 and the flat plate 11 together, and the obliquely arranged side plate 122 can save space. The top plate 121 is used to space from the flat plate 11 to form a cavity, which is convenient for handling.

[0067] See you again Figure 1 Optionally, the plate 11 has a plurality of through holes 110 arranged at intervals along the outer periphery of the plate 11.

[0068] In the above implementation, the through hole 110 not only reduces the weight of the detection device, but also facilitates the arrangement of fasteners so as to fix the detection substrate 1 on the platform.

[0069] Optionally, the plate 11 is a square plate with chamfered corners at all four corners.

[0070] In the above implementation, sharp edges in the structural components can cause localized stress concentration, easily becoming crack initiation points, leading to structural fatigue or fracture. Therefore, chamfering at the four corners of the detection substrate 1 can smoothly transition stress distribution by rounding or beveling, significantly reducing stress peaks. Furthermore, without chamfering, the sharp corners of the detection substrate 1 may scratch operators or damage other components.

[0071] The working process of the detection device provided in this embodiment is briefly described below:

[0072] During testing, the testing substrate 1 is placed on the platform, and the actuator is moved so that its first side faces the testing substrate. Next, the pin holes in the actuator are aligned with the positioning pins, and each connecting hole is aligned with each testing pin 3. Then, the first side of the actuator is attached to the top surface of each support column 2 so that the actuator is positioned on the support column 2. At the same time, it is observed whether each testing pin can pass smoothly through the corresponding connecting hole.

[0073] If the detection pin 3 cannot pass smoothly through the corresponding connecting hole, it indicates that the positional relationship of the connecting holes does not meet the requirements. If the detection pin 3 can pass smoothly through the corresponding connecting hole, it indicates that the positional relationship of the connecting holes meets the requirements.

[0074] The above are merely optional embodiments of this disclosure and are not intended to limit this disclosure. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this disclosure should be included within the protection scope of this disclosure.
