Description

Technical Field

[0001] This utility model relates to the field of air compressor housing technology, specifically to an air compressor housing air tightness testing mechanism that is easy to seal. Background Technology

[0002] An air compressor enclosure air tightness testing agency refers to a complete set of specialized equipment and systems used to test the air tightness of air compressor enclosures (casing, outer shell, etc.). Its core objective is to determine whether there is air leakage in the enclosure under specified test conditions, as well as the size and location of the leakage, so as to ensure the performance, reliability and safety of the equipment in actual use. Chinese Patent CN220039759U discloses an airtightness testing mechanism, including a frame and a plate. A testing component is located above the frame. This component includes a lead screw slide, an electric push rod, a sealing cover, a pusher cylinder, a first horizontal plate, a second horizontal plate, a telescopic rod, and a sealing plate. The lead screw slide is bolted to the center of the bottom side of the plate. The first horizontal plate is fixedly connected to the moving end of the lead screw slide. This invention, by setting a sealing plate inside the sealing cover, allows the pusher cylinder to drive the sealing plate downwards to adhere to the upper wall of the material, based on the material's size. Because the sealing plate slides against the inner wall of the sealing cover, it maintains a relatively stable sliding direction. By reducing the distance between the sealing cover and the material, the sealing space is reduced, shortening the time required for material testing and thus improving the testing efficiency of the equipment.

[0003] Based on existing solutions and actual production and processing applications, the existing air compressor housing air tightness testing mechanism causes slight positional deviations each time the housing is placed during air tightness testing, resulting in incomplete sealing. This can easily lead to edge leakage and air accumulation in dead corners, causing unstable test results or misjudgments. Therefore, we propose an air compressor housing air tightness testing mechanism that is easy to seal in order to solve the problems mentioned above. Utility Model Content

[0004] The purpose of this utility model is to provide an air compressor housing air tightness testing mechanism that is easy to seal, so as to solve the problem mentioned in the background art that the current air compressor housing air tightness testing mechanism causes a slight positional deviation each time the housing is placed, resulting in poor sealing and easy leakage at the edges and accumulation of air in dead corners.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an air compressor housing airtightness testing mechanism that is easy to seal, comprising a base: A mounting frame is fixedly installed on the top of the base, and guide rods are fixedly installed on both the left and right ends of the top of the base. A support plate is slidably connected to the body of the guide rod. An adjustment component is provided on the top of the base. A sealing box is provided above the support plate. A sealing component is provided on the frame of the mounting frame, and a clamping component is provided in the inner cavity of the sealing box.

[0006] Preferably, the adjustment assembly includes a moving groove, a synchronous pulley, a belt, a hinge block, and a motor. The moving groove is fixedly installed at the middle position of the top of the base. The front and rear ends of the moving groove are rotatably connected to the synchronous pulleys, and the synchronous pulleys are connected together by a belt sleeve. The top of the moving groove is slidably connected to the hinge block. The rear end of the top of the base is fixedly installed with the motor, and the output end of the motor is connected to the left end shaft of the synchronous pulley at the rear of the moving groove.

[0007] Preferably, the lower end of the hinge block is connected to the belt body, and the upper end of the hinge block is connected to the middle position of the bottom of the support plate.

[0008] Preferably, the sealing assembly includes a sliding rod, an electric push rod, and a placement groove. Sliding rods are fixedly installed at both ends of the top of the mounting frame, and the sliding rods are symmetrically arranged about the vertical central axis of the mounting frame. The lower end of the sliding rod is fixedly connected to the side wall of the mounting frame, and the rod body is slidably connected to the sealing box. An electric push rod is fixedly installed at the rear end of the top of the mounting frame, and a placement groove is provided at the middle position of the support plate.

[0009] Preferably, the output end of the electric push rod is fixedly connected to the rear end of the sealing box, and the outer ring size of the sealing box is consistent with the size of the placement groove.

[0010] Preferably, the clamping assembly includes a support rod, a clamping plate, a connecting block, and a ball screw. The support rod is slidably connected to both the front and rear ends of the side wall of the sealing box. The support rods are symmetrically arranged vertically and horizontally about the vertical center axis of the sealing box. A clamping plate is fixedly installed at one end of the support rod about the inner cavity of the sealing box, and a connecting block is fixedly installed at the other end of the support rod about the outside of the sealing box. A ball screw is rotatably connected to the middle position of both the left and right ends of the sealing box, and the body of the ball screw is connected to the connecting block through a thread.

[0011] Compared with the prior art, the present invention has at least the following beneficial effects: The air tightness testing mechanism for the air compressor housing that is easy to seal ensures the accuracy and uniqueness of the seal through the cooperation between the lifting and lowering of the sealing box and the placement slot, forming a complete sealed container, thereby reducing false alarms caused by poor sealing. At the same time, the movement of the support plate ensures that the housing maintains the same geometric posture before and after sealing, and reduces edge leakage caused by misalignment or displacement of the housing, so that each test is carried out under the same positioning reference. Then, the clamping plate ensures that the sealing surface and the test chamber are aligned in the same way, reducing poor sealing caused by housing position movement, thereby making the test results more stable and repeatable. 1. The outer ring of the sealing box is the same size as the placement groove, and the output end of the electric push rod is fixedly connected to the rear end of the sealing box. The operation of the electric push rod can drive the sealing box to slide on the sliding rod, thereby pushing the sealing box to fit precisely into the placement groove. This ensures that the box placed in the placement groove is in a closed state. The lifting and lowering of the sealing box and the cooperation between it and the placement groove ensure the accuracy and uniqueness of the seal, forming a complete sealed container. This reduces false alarms caused by poor sealing and improves the overall airtightness. 2. The lower end of the hinge block is connected to the belt body, and the upper end of the hinge block is connected to the middle position of the bottom of the support plate. They are connected by a belt through a synchronous pulley. The operation of the motor and the cooperation between the synchronous pulley and the belt can drive the hinge block to slide on the top of the moving groove. The moving groove can drive the support plate to slide on the rod of the guide rod, thereby aligning the box placed in the groove with the sealing box. The movement of the support plate can ensure that the box maintains the same geometric posture before and after sealing, and reduce edge leakage caused by misalignment or deviation of the box. This ensures that each test is carried out under the same positioning reference, thereby improving the repeatability and comparability of test data. 3. The ball screw is connected to the connecting block via a threaded connection. By rotating the ball screw and through the cooperation between the connecting block and the support rod, the support rod can be extended or retracted via the ball screw. By synchronously rotating the two sets of ball screws, the support rod causes the clamping plates to move closer together. The clamping plates can then hold the box placed inside the sealing chamber. The clamping plates ensure that the sealing surface and the test chamber are aligned, reducing poor sealing caused by box movement and ensuring uniform sealing at the test edges, thus resulting in more stable and repeatable test results.

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model, so that the implementation process of how the present application uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0015] In order to solve the technical problem that the existing air compressor housing air tightness testing mechanism causes a slight positional deviation each time the housing is placed, resulting in poor sealing and easy leakage at the edges and accumulation of air in dead corners, this embodiment discloses the following technical content. Please see Figures 1-5 An easy-to-seal air compressor housing air tightness testing mechanism includes a base 1, a mounting bracket 2, a guide rod 3, a support plate 4, a moving groove 5, a synchronous pulley 6, a belt 7, a hinge block 8, a motor 9, a sliding rod 10, a sealing box 11, an electric push rod 12, a placement groove 13, a support rod 14, a clamping plate 15, a connecting block 16, and a ball screw 17. like Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, when performing an air tightness test on the air compressor housing, the air compressor housing is placed in the placement groove 13 because the support plate 4 has a placement groove 13. Then, the motor 9 at the top rear end of the base 1 is controlled by the controller. The output end of the motor 9 is connected to the left end shaft of the synchronous pulley 6 at the rear of the moving groove 5, and is connected to the front and rear sets of synchronous pulleys 6 inside the moving groove 5 by a belt 7. At the same time, the lower end of the sliding hinge block 8 at the top of the moving groove 5 is connected to the belt body of the belt 7, and the upper end of the hinge block 8 is connected to the middle position of the bottom of the support plate 4. When the motor 9 runs in both directions, it is connected to the synchronous pulleys... The cooperation between 6 and belt 7 can drive the hinge block 8 to slide on the top of the moving groove 5, and cause the hinge block 8 to drive the support plate 4 to slide on the rod of the guide rod 3. Thus, by the support plate 4 sliding on the rod of the guide rod 3, the support plate 4 can synchronously drive the air compressor box in the placement groove 13 to move synchronously, thereby adjusting the air compressor box in the placement groove 13 to be directly below the sealing box 11, and ensuring that the air compressor box in the placement groove 13 is aligned with the inner cavity of the sealing box 11. The movement of the support plate 4 can ensure that the box maintains the same geometric posture before and after sealing, and reduce edge leakage caused by misalignment or deviation of the box, so that each test is carried out under the same positioning reference. like Figure 1 , Figure 2 , Figure 3 and Figure 5 As shown, when the air compressor housing in the placement slot 13 is directly below the sealing box 11, the electric push rod 12 can be controlled by the controller. The output end of the electric push rod 12 is fixedly connected to the rear end of the sealing box 11 and slides together with the sliding rod 10 on the mounting frame 2 through the sealing box 11. At the same time, the outer ring size of the sealing box 11 is consistent with the size of the placement slot 13. When the electric push rod 12 is running, it can drive the sealing box 11 to slide on the rod of the sliding rod 10. Thus, the operation of the electric push rod 12 can insert the sealing box 11 into the placement slot 13 and make the outer ring of the sealing box 11 fit precisely with the placement slot 13. This places the air compressor housing in the placement slot 13 in a closed space. The lifting and lowering of the sealing box 11 and the cooperation between the placement slot 13 ensure the accuracy and uniqueness of the seal, forming a complete sealed container and improving the overall airtightness. like Figure 1 , Figure 2 , Figure 3 and Figure 5As shown, when the air compressor housing is placed in the enclosed space between the sealing box 11 and the placement slot 13, the ball screws 17 at both ends of the sealing box 11 can rotate synchronously. This is because the ball screw 17 is threadedly connected to the connecting block 16. Since the side wall of the sealing box 11 is slidably connected to a support rod 14, and a clamping plate 15 is fixedly installed at one end of the support rod 14 relative to the inner cavity of the sealing box 11, and a connecting block 16 is fixedly installed at the other end of the support rod 14 relative to the outside of the sealing box 11, when the ball screw 17 is rotated, it passes through the connecting block... 16 drives the support rod 14 to extend and retract, and causes the support rod 14 to slide on the side wall of the sealing box 11. The sliding of the support rod 14 can drive the clamping plate 15 to move. Then, through the movement of the two sets of clamping plates 15, the two sets of clamping plates 15 are brought closer to the air compressor housing, so that the clamping plates 15 are tightly fitted with the side wall of the air compressor housing, thereby fixing the air compressor housing in the cavity of the sealing box 11. The clamping plates 15 can ensure that the sealing surface and the test cavity are aligned, reduce the sealing problems caused by the movement of the housing, and ensure uniform sealing of the test edge.
