Description

Technical Field

[0001] This invention relates to the field of pressure boosting device testing technology, and more specifically to a pressure testing device for a pressure boosting device. Background Technology

[0002] Currently, the turbocharger, as a core component for increasing the intake air volume and cylinder charge density of an internal combustion engine, directly determines the engine's efficiency and power output. The turbocharger housing, as the load-bearing and protective structure of the turbocharger, must withstand the continuous pressure from compressed air. Therefore, during its production and processing, the pressure-bearing capacity of the housing must be rigorously tested to ensure that it meets quality standards and guarantees the safe and stable operation of the turbocharger.

[0003] In the prior art, there are already related devices for pressure testing of turbocharger housings. For example, Chinese utility model patent with publication number CN218646762U discloses a pressure testing device for compressor housings. The device includes a testing platform, a positioning retaining ring, a drive unit, and a drive device. During operation, the compressor housing is clamped and positioned by the positioning retaining ring, and then the pressure block of the drive unit moves towards the housing and applies pressure, thereby realizing the pressure testing of the housing. This ensures the stability of the testing process and the accuracy of the data to a certain extent.

[0004] However, the aforementioned existing testing devices and similar fixed-structure testing equipment still have significant drawbacks in practical applications: the testing mechanism of such devices is in a fixed position and can only perform pressure testing on a single preset point on the turbocharger housing; when other areas of the housing need to be tested, the testing position must be adjusted by moving the turbocharger housing. However, turbocharger housings are usually large in size and weight, and the load-bearing space of the testing platform is limited. Moving them manually or using conventional auxiliary mechanisms is cumbersome, time-consuming, and labor-intensive, resulting in low testing efficiency and difficulty in comprehensively assessing the overall pressure-bearing performance of the housing, thus failing to meet the needs for efficient and comprehensive quality testing of turbocharger housings. Summary of the Invention

[0005] The purpose of this invention is to overcome the shortcomings of the prior art and provide a pressure testing device for a pressurization device. This addresses the problems of existing testing equipment, such as fixed testing mechanisms, single-point testing capability, cumbersome operation due to the need to move the bulky housing, poor testing coverage, low efficiency, and difficulty in comprehensively evaluating the housing's pressure-bearing performance.

[0006] To achieve the above objectives, the present invention employs the following technical solutions: A pressure testing device for a booster includes a testing platform (1), a support frame (2) fixedly connected to the upper end of the testing platform (1), a drive unit (3) installed on the top of the support frame (2), the output end of the drive unit (3) passing through the support frame (2) and connected to a test component (4), and a fixing component (5) is provided on the testing platform (1). The test component (4) includes a mounting base (41), which is fixedly connected to the output end of the drive unit (3). Several evenly arranged connecting columns (42) are installed below the mounting base (41), and a test head (43) is installed at the lower end of each connecting column (42). The pressure test can be performed on multiple points of the turbocharger housing at the same time. The test coverage can be expanded without moving the turbocharger housing, which solves the limitation of single-point testing of existing equipment, greatly improves the testing efficiency, and can more comprehensively evaluate the overall pressure performance of the housing.

[0007] As a preferred embodiment, the connecting column (42) is configured as a hollow structure, and a pressure sensor (6) is also installed inside the connecting column (42). One end of the pressure sensor (6) extends through the connecting column (42) into the interior of the test head, which can directly and accurately collect the pressure data applied to the shell by the test head (43), ensuring the accuracy of the test data and providing a reliable basis for the quality assessment of the shell.

[0008] As a preferred embodiment, the fixing component (5) includes a storage slot (51) installed on the testing platform (1). A vertical clamp (52) is installed on the upper end of the storage slot (51). The storage slot (51) in the fixing component (5) works in conjunction with the vertical clamp (52) to securely fix the booster housing on the testing platform (1). This eliminates the need for manual or auxiliary mechanisms to move the bulky housing to adjust the testing position, reducing the difficulty of operation and saving operation time.

[0009] As a preferred embodiment, two sets of symmetrical guide columns (7) are fixedly connected between the testing platform (1) and the support frame (2). The mounting base (41) is slidably disposed on the outside of the two sets of guide columns (7). The guide columns (7) guide the mounting base (41), making the mounting base (41) drive the test component (4) to move up and down more smoothly, and avoiding the test head (43) from deviating and affecting the testing accuracy.

[0010] As a preferred embodiment, the mounting base (41) includes a connecting plate (411), a mounting plate (412), and a connecting seat (413). The connecting seat (413) is threadedly connected to the output end of the drive unit (3). The connecting seat (413) is connected to the connecting plate (411) by bolts. The connecting plate (411) is fixedly connected to the mounting plate (412). The bottom of the mounting plate (412) is provided with a T-shaped groove (4121). The upper end of the connecting column (42) is provided with a T-shaped slider (421) that matches the T-shaped groove (4121). The T-shaped groove (4121) at the bottom of the mounting plate (412) cooperates with the T-shaped slider (421) at the upper end of the connecting column (42). The position of the connecting column (42) and the test head (43) can be adjusted according to the testing requirements of different specifications of turbocharger housings, thereby improving the versatility of the equipment.

[0011] As a preferred method, the drive unit (3) adopts a drive cylinder or a hydraulic cylinder; by flexibly selecting the drive method, the fast response and low cost of the drive cylinder and the high pressure and high precision of the hydraulic cylinder are used to jointly construct an efficient, reliable and economical testing scheme, which is suitable for the full-scene testing of various pressure-bearing components such as the turbocharger housing.

Detailed Implementation

[0017] The present invention will now be described in detail with reference to the accompanying drawings.

[0018] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0019] Example 1: like Figures 1-4 As shown, A pressure testing device for a booster device includes a testing platform (1). The testing platform (1) is made of high-strength stainless steel to ensure load-bearing stability and corrosion resistance. A support frame (2) is fixedly connected to its upper end by bolts. The support frame (2) is similar to a protective cover with one end open. Except for the side facing the operator, the other three sides and the top are equipped with protective panels. The opening width of the open side is adapted to the needs of picking up and putting down the booster housing. It can effectively protect the test components (4) and other components inside the device, avoid external debris from interfering with the testing process or the components from being damaged by accidental collisions, and facilitate the operator to place, fix and observe and operate the booster housing on the open side. A drive unit (3) is installed on the top of the support frame (2). Its output end passes through the through hole in the center of the protective panel on the top of the support frame (2) and is connected to the test component (4). A fixing component (5) is provided on the testing platform (1) for fixing the booster housing.

[0020] The test component (4) includes a mounting base (41), connecting posts (42) and a test head (43). The mounting base (41) is fixedly connected to the output end of the drive unit (3). Several evenly arranged connecting posts (42) are installed below the mounting base (41). The number of connecting posts (42) can be set to 6 to 8 according to actual testing requirements. There is a certain distance between two adjacent connecting posts (42). When the pressure test is performed on the turbocharger housing, the pressure of the test head (43) is not too concentrated, which may damage the turbocharger housing. The lower end of each connecting post (42) is threaded with a test head (43). The test head (43) is made of wear-resistant rubber material to avoid scratching the surface of the housing during testing.

[0021] The connecting column (42) is designed as a hollow structure. A pressure sensor (6) is installed inside the connecting column (42). The test head (43) includes an interconnected mounting column (431) and a pressure block (432). The mounting column (431) is threadedly connected to the connecting column (42). One end of the pressure sensor (6) passes through the connecting column (42) and the mounting column (431) and extends to the lower end of the pressure block (432). It can directly detect the pressure applied to the housing by the test head (43) to ensure accurate test data.

[0022] The fixing component (5) includes a storage slot (51) installed on the testing platform (1). The storage slot (51) is fixed in a preset position on the testing platform (1), and the storage slot (51) is located in the area of ​​the testing platform (1) corresponding to the open side of the support frame (2), so that the operator can place the booster housing on the storage slot (51) from the open side. A vertical clamp (52) is installed at the upper end of the storage slot (51). It should also be noted that the vertical clamp (52) is existing technology, and its structure will not be described in detail here. The device uses the Jiagang brand vertical clamp, which can facilitate the operator to quickly clamp or loosen the booster housing on the open side to ensure the stability of the housing position during the testing process.

[0023] Two sets of symmetrical guide columns (7) are fixedly connected between the detection platform (1) and the support frame (2). The two sets of guide columns (7) are respectively set close to the two sides of the open side of the support frame (2). The mounting seat (41) has sliding holes on both sides that match the guide columns (7). The mounting seat (41) is slidably set on the outside of the two sets of guide columns (7). The guide columns (7) can restrict the movement direction of the mounting seat (41) and prevent the mounting seat (41) from shifting during the up and down movement, thereby improving the detection accuracy. At the same time, the guide columns (7) can also further enhance the structural stability of the support frame (2) and improve the overall protection effect in conjunction with the protective cover structure.

[0024] The mounting base (41) includes a connecting plate (411), a mounting plate (412), and a connecting seat (413). The connecting seat (413) is threadedly connected to the output end of the drive unit (3). The connecting seat (413) is connected to the connecting plate (411) by bolts for easy disassembly and maintenance. The connecting plate (411) is fixedly connected to the mounting plate (412). The bottom of the mounting plate (412) is provided with a T-shaped groove (4121). The upper end of the connecting column (42) is provided with a T-shaped slider (421) that matches the T-shaped groove (4121). 421) It can slide in the T-shaped slide (4121) to adjust the position of the connecting column (42) and the test head (43) to meet the testing requirements of different points. There is no need to move the housing. The operator can observe and adjust the position of the connecting column (42) from the open side of the support frame (2). The operation is convenient. Both ends of the T-shaped slide (4121) are provided with disassembly ports. The top and side walls of the T-shaped slide (4121) are provided with several one-to-one corresponding mounting holes and fixing holes, which facilitates the disassembly and replacement of the connecting column (42) according to the testing requirements of the turbocharger housing.

[0025] The drive unit (3) uses either a pneumatic cylinder or a hydraulic cylinder. Pneumatic cylinders have the characteristics of fast response and low cost, while hydraulic cylinders have the characteristics of high pressure and high precision. They can be flexibly selected and are suitable for full-scene testing of various pressure-bearing components such as the turbocharger housing.

[0026] Working principle In use, first place the booster housing in the groove of the storage slot (51) and clamp the housing with the vertical clamp (52); according to the points that need to be tested on the housing, push the connecting column (42) so that the T-shaped slider (421) slides in the T-shaped groove (4121). After adjusting the position of the test head (43), fix the connecting column (42) with the set screw; start the drive cylinder (or hydraulic cylinder), and the output end of the drive cylinder (or hydraulic cylinder) pushes the mounting base (41) to move downward along the guide column (7) so that the test head (43) contacts the surface of the housing and applies pressure; the pressure sensor (6) detects the pressure applied by the test head (43) in real time to ensure that the applied pressure is within the set range. The operator judges whether the booster housing meets the requirements by judging whether the booster housing deforms within the set pressure range; after the test is completed, the drive cylinder (or hydraulic cylinder) drives the test component (4) to reset, release the vertical clamp (52), and take out the housing.

[0027] In this embodiment, the present invention can quickly adjust the detection points and achieve multi-area detection without moving the housing. The detection efficiency is improved by more than 30% compared with the existing equipment. Moreover, the detection point error is small and the pressure detection accuracy is high, which can fully meet the needs of efficient and accurate pressure testing of the booster housing.

[0028] This invention is not limited to the specific embodiments described above. The invention extends to any new feature or combination disclosed in this specification, as well as any new method or process step or combination disclosed herein.
