Description

Technical Field

[0001] The utility model relates to the technical field of engine detection, in particular to an engine sealing detection device. Background Art

[0002] An engine is a device that converts the chemical energy of fuel or other forms of energy into mechanical energy. It is widely used in vehicles such as automobiles, aircraft, and ships, as well as in industrial equipment. Based on their operating principles, engines can be divided into two types: internal combustion engines and external combustion engines. Internal combustion engines burn fuel and convert energy internally, while external combustion engines burn fuel externally and convert the generated heat into mechanical energy. Engines are tested for leaks before leaving the factory.

[0003] Chinese patent publication number CN212844239U discloses a device for detecting the sealing of automobile engines. The device uses a vacuum mechanism to create a vacuum state inside the test box to prevent the test environment from affecting the test results. When the engine leaks, the pointer of the pressure gauge rises, and the pressure sensor transmits data to the control panel in real time for observation by the workers. The movable plate is driven by a hydraulic cylinder to move, so that the engine is clamped and fixed between the movable plate and the fixed plate, thereby preventing the engine from shaking.

[0004] Since the engine is heavy, it takes a certain amount of time to place and remove it. However, the above patent will cause the detection process to be interrupted when placing and removing the engine, thereby affecting the detection efficiency. Utility Model Content

[0005] The purpose of the utility model is to provide an engine sealing detection device, which effectively solves the problems raised in the above background technology.

[0006] In order to achieve the above-mentioned purpose, the present utility model provides the following technical solutions.

[0007] An engine seal testing device comprises a housing with openings on both the front and rear sides. A support plate is disposed within the housing, and a partition is mounted on the upper surface of the support plate, dividing the support plate into two testing areas. Both testing areas are provided with fixing devices. Side panels are mounted on both ends of the support plate. Two parallel support plates are mounted on the bottom of the housing. A movement mechanism capable of driving the horizontal movement of the support plate is provided on the upper surface of the support plates.

[0008] It can be seen that when the supporting plate is moved horizontally to either end by the moving mechanism, one of the detection areas will be located inside the box to form a detection space, while the other detection area will be located outside the box. Therefore, while the engine is being tested, the engine can be placed and removed in the outside detection area, thereby avoiding interruption of the detection process when the engine is placed and removed, and improving detection efficiency.

[0009] Furthermore, the moving mechanism includes a mounting groove opened on the upper surface of the support plate, a threaded rod is arranged inside the mounting groove, a motor is installed on the outer surface of the support plate, the output shaft of the motor is connected to the threaded rod, a drive plate is installed on the outer surface of the threaded rod, and the top of the drive plate is connected to the lower surface of one of the side plates.

[0010] Furthermore, a groove is provided on the inner wall of the box, and sealing plates are provided on the four sides of the groove. The outer surface of the sealing plate is connected to a guide rod, the end of the guide rod passes through the outside of the box and is installed with a wedge plate, and a wedge frame is provided on the outer surface of the box. Electric push rods are installed on the outer surfaces of both sides of the box, and the end of the telescopic end of the electric push rod is connected to the wedge frame.

[0011] Furthermore, a spring is sleeved on the outer surface of the guide rod, and two ends of the spring are respectively in contact with the box body and the wedge plate.

[0012] Furthermore, slide bars are installed on the upper and lower outer surfaces of the box body, and linear bearings are slidably installed on the outer surfaces of the slide bars, and the linear bearings are connected to the wedge frame.

[0013] Furthermore, a sealing gasket is provided on the side of the side plate facing the partition plate.

[0014] Furthermore, a sliding groove is provided on the side of the upper surface of the support plate away from the moving mechanism, a slider is provided inside the sliding groove, and the end of the slider is connected to the lower surface of the other side plate.

[0015] Furthermore, the outer surface of the wedge plate is connected to two guide rods, and the two guide rods are symmetrically distributed along the length direction of the wedge plate.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows.

[0017] 1. When the carrying plate is moved horizontally to either end by the moving mechanism of the present invention, one of the detection areas is located inside the box to form a detection space, while the other detection area is located outside the box. Therefore, the engine can be placed and removed in the outer detection area while the engine is being detected, thereby avoiding interruption of the detection process when the engine is placed and removed, and improving detection efficiency.

[0018] 2. The utility model starts the electric push rod, and its telescopic end pushes the wedge frame to move. Since the inclined surface of the wedge frame and the inclined surface of the wedge plate are squeezed against each other, the wedge plate can be driven to move toward the surface of the box body, and the sealing plate is driven to move by the guide rod, so that the four sealing plates are respectively pressed against the outer surfaces of the bearing plate and the partition plate to form a seal, thereby improving the sealing inside the box body and avoiding leakage caused by the gap between the bearing plate and the partition plate and the inner wall of the box body.

[0028] See also Figure 1-Figure 5 The present invention provides an engine seal detection device, comprising a housing 100, with openings provided on both the front and rear sides of the housing 100. A carrier plate 101 is disposed within the housing 100, with a partition plate 102 mounted on the upper surface of the carrier plate 101. The partition plate 102 divides the carrier plate 101 into two detection areas 103, each of which is provided with a fixing device 106. Side panels 104 are mounted on both ends of the carrier plate 101, and two mutually parallel support plates 105 are mounted on the bottom of the housing 100. A moving mechanism 200 capable of driving the carrier plate 101 to move horizontally is provided on the upper surface of the support plates 105.

[0029] During use, the worker first places the engine in the inspection area 103 located on the outside, fixes the engine with the fixing device 106, and then drives the supporting plate 101 to move horizontally to the other end through the moving mechanism 200, so that the engine originally on the outside enters the box body 100, and due to the blocking effect of the side plate 104 and the partition plate 102, a detection space can be formed inside the box body 100, and the other detection area 103 is moved out of the outside of the box body 100. Therefore, while the engine is being inspected, the next engine to be inspected can be placed on the inspection area 103 on the outside. When the engine located inside the box body 100 completes the inspection, it is pushed out by the moving mechanism 200, so that the engine originally on the outside enters the box body 100 for direct inspection, and the engine that has completed the inspection is on the outside, thereby avoiding the interruption of the inspection process when the engine is placed and removed, thereby improving the inspection efficiency. It is worth noting that the fixing device 106 and the sealing detection principle in this application are consistent with the comparative patent, so no further details are given here.

[0030] Specifically, the moving mechanism 200 includes a mounting groove 201 opened on the upper surface of the support plate 105, a threaded rod 202 is provided inside the mounting groove 201, a motor 203 is installed on the outer surface of the support plate 105, the output shaft of the motor 203 is connected to the threaded rod 202, and a driving plate 204 is installed on the outer surface of the threaded rod 202. The top of the driving plate 204 is connected to the lower surface of one of the side plates 104. When the motor 203 is started, its output shaft drives the threaded rod 202 to rotate. Since the inner wall of the mounting groove 201 limits the driving plate 204, the driving plate 204 can move along the length direction of the threaded rod 202 and achieve the purpose of driving the supporting plate 101 to move horizontally.

[0031] Specifically, a groove 300 is provided on the inner wall of the box body 100, and sealing plates 301 are provided on the four sides of the groove 300. The outer surface of the sealing plate 301 is connected to a guide rod 302. The end of the guide rod 302 passes through the outer side of the box body 100 and is installed with a wedge plate 303. The outer surface of the box body 100 is provided with a wedge frame 304. Electric push rods 305 are installed on the outer surfaces of both sides of the box body 100. The end of the telescopic end of the electric push rod 305 is connected to the wedge frame 304. Since the sealing of the internal space needs to be guaranteed when the engine sealing test is performed, when the partition plate 102 is opened, the sealing plate 302 is opened. After moving to the designated position, the electric push rod 305 can be started, and its telescopic end pushes the wedge frame 304 to move. Since the inclined surface of the wedge frame 304 and the inclined surface of the wedge plate 303 are pressed against each other, the wedge plate 303 can be driven to move toward the surface of the box body 100, and the sealing plate 301 can be driven to move through the guide rod 302, so that the four sealing plates 301 are respectively pressed against the outer surfaces of the supporting plate 101 and the partition plate 102 to form a seal, thereby improving the sealing of the interior of the box body 100 and avoiding leakage caused by the gap between the supporting plate 101 and the partition plate 102 and the inner wall of the box body 100.

[0032] Specifically, a spring 400 is sleeved on the outer surface of the guide rod 302, and the two ends of the spring 400 are respectively in contact with the box body 100 and the wedge plate 303. When the wedge plate 303 moves toward the surface of the box body 100, the spring 400 is compressed. When the wedge frame 304 separates from the surface of the wedge plate 303, the compressed spring 400 releases its elastic force, which can push the wedge plate 303 to return to its original position and separate the sealing plate 301 from the outer surfaces of the supporting plate 101 and the partition plate 102, thereby facilitating the movement of the supporting plate 101 inside the box body 100.

[0033] Specifically, sliding rods 500 are installed on the upper and lower outer surfaces of the box body 100, and linear bearings 501 are slidably installed on the outer surface of the sliding rods 500. The linear bearings 501 are connected to the wedge frame 304. Through the arrangement of the sliding rods 500 and the linear bearings 501, the wedge frame 304 can be provided with the ability of limiting guidance, thereby ensuring its smoothness and stability during movement.

[0034] Specifically, a sealing gasket 600 is provided on the side of the side panel 104 facing the partition panel 102. When the side panel 104 and the surface of the box body 100 are closed and pressed tightly, the sealing gasket 600 can play a sealing role between the two to avoid leakage and improve detection accuracy.

[0035] Specifically, a slide groove 700 is provided on the side of the upper surface of the support plate 105 away from the moving mechanism 200, and a slider 701 is provided inside the slide groove 700. The end of the slider 701 is connected to the lower surface of the other side plate 104. Through the setting of the slide groove 700 and the slider 701, not only can the side plate 104 be provided with support capacity and the structural stability of the side plate 104 and the supporting plate 101 be improved, but also a guiding function can be provided to make it stable and smooth when sliding.

[0036] Specifically, two guide rods 302 are connected to the outer surface of the wedge plate 303. The two guide rods 302 are symmetrically distributed along the length direction of the wedge plate 303. The provision of the two guide rods 302 improves the connection strength between the wedge plate 303 and the sealing plate 301, ensuring that the four wedge plates 303 can be squeezed by the wedge frame 304 at the same time.

[0037] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be encompassed within the present invention. Any reference sign in a claim should not be construed as limiting the claim to which it relates.
