It includes a base, the upper surface of which has a feeding groove matching the shape of a finned heat sink. Inspection plates for flatness inspection of the finned heat sink are positioned above both ends of the feeding groove. Both ends of the inspection plates are slidably connected to the upper surface of the base via a sliding guide mechanism. This utility model, through the cooperation of the inspection plates and the sliding guide mechanism, moves the inspection plates and utilizes the gap between the inspection plates and the finned heat sink to perform flatness inspection on the finned heat sink placed in the feeding groove.

Description

Technical Field

[0001] This utility model relates to the field of product inspection tool technology, specifically a large module hole position and flatness inspection tool. Background Technology

[0002] Finned radiators are common heat exchange devices on the market. By adding fins (such as aluminum or steel strips) to the surface of a base tube (such as a steel or copper tube), the heat dissipation area is significantly increased, improving heat exchange efficiency. Figure 5 As shown, in order to prevent product deformation and hole misalignment, it is necessary to inspect the hole position and flatness during the production of finned heat sinks.

[0003] However, the flatness inspection of finned heat sinks reflects the flatness of the substrate or fin surface, requiring high-precision surface scanning equipment (such as laser interferometers). Hole position inspection verifies whether the position, diameter, and spacing of the holes meet the design requirements. These two are different dimensions of geometric tolerances and require different physical parameters (surface flatness vs. geometric position) and inspection equipment. They usually need to be inspected step by step to ensure independent verification of accuracy and meet manufacturing standards.

[0004] However, step-by-step inspection increases the number of times the finned heat sink is transferred and loaded / unloaded, prolonging the inspection cycle and thus affecting the quality inspection efficiency of the finned heat sink. Therefore, we need to propose a large module hole position and flatness inspection fixture to solve the above problems, so that hole position and flatness can be inspected simultaneously, effectively improving the inspection efficiency of the finned heat sink. Utility Model Content

[0005] The purpose of this invention is to provide a large module hole position and flatness inspection tool that can simultaneously inspect hole position and flatness, effectively improving the inspection efficiency of finned heat sinks and solving the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a large module hole position and flatness inspection tool, including a base, the upper surface of which is provided with a feeding groove matching the shape of a finned heat sink, and an inspection plate for inspecting the flatness of the finned heat sink is provided above both ends of the feeding groove, and both ends of the inspection plate are slidably connected to the upper surface of the base through a sliding guide mechanism.

[0007] The inside of the feeding trough is equipped with a detection component for detecting holes at different positions on the finned heat sink. Between the two detection plates is a pressurizing mechanism for applying pressure to the finned heat sink. The pressurizing mechanism is connected to the base via a height-adjustable bracket.

[0008] Preferably, the detection component includes multiple intermediate hole detection columns and multiple edge hole detection columns. The intermediate hole detection columns are detachably installed on both sides of the middle part of the discharge trough, and the multiple edge hole detection columns are detachably installed at both ends of the discharge trough.

[0009] Preferably, both the intermediate hole detection post and the edge hole detection post include a column threadedly connected to the bottom of the discharge trough, and the lower end of the column is provided with a stud for screwing into the bottom of the discharge trough.

[0010] Preferably, the sliding guide mechanism includes a guide rail and a slider that slides on the guide rail. The guide rail is fixed on the base located on both sides of the material discharge trough, and the guide rails on both sides are symmetrical about the center of the material discharge trough.

[0011] Preferably, the detection plate has multiple mounting holes at both ends, and the two ends of the detection plate are fixed to the slider by fixing screws.

[0012] Preferably, the bracket includes a vertical plate, on which a mounting seat is slidably mounted. The vertical plate has an elongated hole for adjusting the height of the mounting seat. The bracket locks the moving position of the mounting seat by a locking screw, and the locking screw passes through the elongated hole and is threaded to one side of the mounting seat. The pressure mechanism is installed on the other side of the mounting seat.

[0013] Preferably, the pressurizing mechanism includes a pressure block and a hand-operated elbow clamp mounted on the other side of the mounting base, the pressure block being mounted on the lower end of the hand-operated elbow clamp.

[0014] Preferably, the feeding trough has a material-receiving notch on the side opposite to the vertical plate, and both ends of the feeding trough have clearance notches for receiving material from both ends of the finned heat sink.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1. This utility model utilizes the cooperation of a detection plate and a sliding guide mechanism. By moving the detection plate, the flatness of the finned heat sink placed in the feeding trough is detected using the gap between the detection plate and the finned heat sink. The gap between the detection plate and the finned heat sink is the requirement for flatness control. The detection components in the feeding trough can detect the holes at different positions on the finned heat sink, allowing the finned heat sink to have its flatness and hole positions detected simultaneously with only one loading and unloading process. This reduces labor costs and effectively improves the detection efficiency of the finned heat sink.

[0017] 2. This utility model, through the cooperation of the bracket and the pressurizing mechanism, can fix the position of the finned heat sink placed in the feeding trough, so that the finned heat sink can remain stable when the test plate is testing the flatness, thereby improving the accuracy of the test.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figure 1-5 This utility model provides a technical solution: a large module hole position and flatness inspection tool, including a base 1. The upper surface of the base 1 is provided with a feeding groove 8 that matches the shape of the finned heat sink 7. The upper ends of the feeding groove 8 are provided with inspection plates 3 for inspecting the flatness of the finned heat sink 7. Both ends of the inspection plates 3 are slidably connected to the upper surface of the base 1 through a sliding guide mechanism 2. The inside of the feeding groove 8 is provided with an inspection component for inspecting the hole positions at different locations on the finned heat sink 7.

[0026] By moving the detection plate 3, the flatness of the finned heat sink 7 placed in the feeding trough 8 is detected using the gap between the detection plate 3 and the finned heat sink 7. The gap between the detection plate 3 and the finned heat sink 7 is the requirement for flatness control. The detection components in the feeding trough 8 can detect the holes at different positions on the finned heat sink 7, so that the flatness and hole positions of the finned heat sink 7 can be detected simultaneously with only one loading and unloading, reducing labor costs and effectively improving the detection efficiency of the finned heat sink 7.

[0027] A pressurizing mechanism 5 for applying pressure to the finned heat sink 7 is provided between the two test plates 3. The pressurizing mechanism 5 is connected to the base 1 through a height-adjustable bracket 4. Through the cooperation of the bracket 4 and the pressurizing mechanism 5, the position of the finned heat sink 7 placed in the discharge trough 8 can be fixed, so that the finned heat sink 7 can remain stable when the test plate 3 is testing the flatness, thereby improving the accuracy of the test.

[0028] The detection assembly includes multiple intermediate hole detection posts 6 and multiple edge hole detection posts 9. The intermediate hole detection posts 6 are detachably installed on both sides of the middle part of the discharge trough 8, and the multiple edge hole detection posts 9 are detachably installed at both ends of the discharge trough 8. The intermediate hole detection posts 6 and edge hole detection posts 9 are flexibly installed according to the actual position of the holes on the actual finned heat sink 7, so that the inspection tool can match the finned heat sink 7 and detect the holes on the finned heat sink 7.

[0029] Both the intermediate hole detection column 6 and the edge hole detection column 9 include a column threadedly connected to the bottom of the discharge trough 8. The lower end of the column is provided with a stud for screwing into the bottom of the discharge trough 8. The column is designed according to the specific shape of the hole on the finned radiator 7. During the inspection, if the column can be inserted into the corresponding hole on the finned radiator 7, it means that the hole is qualified. If the column cannot be inserted into the corresponding hole on the finned radiator 7, it is determined that there is an abnormality in the hole of the finned radiator 7.

[0030] The sliding guide mechanism 2 includes a guide rail 21 and a slider 22 that slides on the guide rail 21. The guide rail 21 is fixed on the base 1 on both sides of the material feeding groove 8, and the guide rail 21 on both sides is symmetrical about the center of the material feeding groove 8, so that the detection plate 3 can slide on the guide rail 21. During the flatness test, if the detection plate 3 can move on the upper surface of the finned heat sink 7 in the material feeding groove 8, it means that the flatness of the finned heat sink 7 meets the quality requirements. If the detection plate 3 cannot move on the finned heat sink 7, it means that the flatness of the finned heat sink 7 is out of specification and does not meet the quality requirements.

[0031] Multiple mounting holes are provided at both ends of the detection plate 3. The two ends of the detection plate 3 are fixed to the slider 22 by fixing screws, so that the detection plates 3 on both sides of the feeding trough 8 span the feeding trough 8 like a bridge. The gap between the detection plate 3 and the finned heat sink 7 is the standard for the flatness quality requirement of the finned heat sink 7. The detection plate 3 is fixed to the slider 22 by fixing screws, so that the detection plate 3 is detachable, which makes it easy to replace different detection plates 3 according to different quality specifications to adjust the distance between the finned heat sink 7 and the detection plate 3.

[0032] The bracket 4 includes a vertical plate 41, on which a mounting base 42 is slidably mounted. The vertical plate 41 has an elongated hole 43 for adjusting the height of the mounting base 42. The bracket 4 locks the position of the mounting base 42 by a locking screw 44, which passes through the elongated hole 43 and is threaded to one side of the mounting base 42. The pressure mechanism 5 is installed on the other side of the mounting base 42. By loosening the locking screw 44, the mounting base 42 can move within the elongated hole 43. After adjusting the position, the locking screw 44 is tightened again to adjust the height of the mounting base 42, thereby adjusting the position of the pressure mechanism 5 and adjusting the pressure applied to the finned heat sink 7. This method is also suitable for testing finned heat sinks 7 of different thicknesses.

[0033] The pressurizing mechanism 5 includes a pressure block 52 and a hand-operated elbow clamp 51 installed on the other side of the mounting base 42. The pressure block 52 is installed at the lower end of the hand-operated elbow clamp 51, which is a commercially available product. It includes a fixed jaw, a movable jaw, a connecting component, and an operating handle. The fixed jaw is connected to the mounting base 42, and the movable jaw is connected to the pressure block 52. The movable jaw moves through the connecting component, such as a four-bar linkage, which transmits the operating force and controls the trajectory of the movable jaw. The operating handle is the input point for manual force application. The power is transmitted through a lever mechanism. By lifting or pressing the operating handle, the pressure block 52 moves up or down to apply pressure to the finned radiator 7 or move away from the finned radiator 7, which facilitates the fixation of the finned radiator 7 placed in the discharge trough 8.

[0034] The material feeding trough 8 is provided with a material taking notch 10 on the side opposite to the vertical plate 41. Both ends of the material feeding trough 8 are provided with clearance notches 11 for taking material from both ends of the finned heat sink 7. The material taking notch 10 and clearance notch 11 are used to facilitate taking the finned heat sink 7 out of the material feeding trough 8 and putting it in.

[0035] During testing, the testing plate 3 is first moved to both ends of the feeding trough 8, and then the finned radiator 7 is placed into the feeding trough 8. If both the middle hole testing column 6 and the edge hole testing column 9 can be inserted into the corresponding positions on the finned radiator 7, the finned radiator 7 can be placed flat into the feeding trough 8, which means that the hole positions of the finned radiator 7 are qualified. Then, the pressure block 52 is moved by the hand-push elbow clamp 51, so that the pressure block 52 abuts against the upper surface of the middle part of the finned radiator 7, fixing the position of the finned radiator 7. At this time, the testing plates 3 at both ends of the feeding trough 8 are moved along the guide rail 21 in opposite directions, so that the testing plates 3 can move across the upper surface of the finned radiator 7. If the testing plates 3 can pass through the finned radiator 7, it is determined that the flatness of the finned radiator 7 meets the quality requirements. If the testing plates 3 cannot pass through the finned radiator 7, it is determined that the flatness of the finned radiator 7 does not meet the quality requirements.

[0036] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
