Description

Technical Field

[0001] This utility model relates to the technical field of sealing component testing equipment, and in particular to a perforated sealing component testing device. Background Technology

[0002] Perforated closures are enclosed structural components with one or more openings, widely used in various industrial fields such as machinery, automobiles, and electronic equipment. These perforated closures typically require rigorous quality inspection during the manufacturing process to ensure that the size, location, and shape of the openings meet design requirements and achieve predetermined functional and safety standards.

[0003] In practice, existing traditional testing equipment requires manual intervention or uses static testing methods, which cannot flexibly adjust the position and angle of the equipment during testing. The overall testing flexibility of the equipment is low. Manual testing is not only time-consuming, but also easily affected by human factors, resulting in low production efficiency.

[0004] Therefore, this utility model provides a detection device for perforated closures. Utility Model Content

[0005] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a detection device for perforated closures.

[0006] To achieve the above objectives, this utility model adopts the following technical solution: a detection device for a perforated closure, including a mounting base plate.

[0007] Two fixing frames are installed on the top of the mounting base plate. The two fixing frames are symmetrically distributed. A top mounting guide rail is installed between the two fixing frames. An auxiliary detection mechanism is slidably connected to one side of the top mounting guide rail.

[0008] The auxiliary detection mechanism includes a movable slide plate. A movable slide plate is slidably connected to one side of the top mounting rail. A mounting block is fixedly connected to the outer side of the movable slide plate. A mounting frame is fixedly connected to the outer side of the mounting block. A laser sensor is rotatably connected inside the mounting frame. A lighting panel is installed at the bottom of the mounting frame, located below the laser sensor. The laser sensor is limited by a limiting shaft on the outer side of the mounting frame. An auxiliary positioning plate is installed on the outer side of the movable slide plate, located on one side of the mounting block. The auxiliary positioning plate has an L-shaped structure. An infrared sensor is installed at the bottom of the auxiliary positioning plate. A sixth positioning bolt, which connects to the infrared sensor, is installed at the top of the auxiliary positioning plate. The infrared sensor and the auxiliary positioning plate are positioned and installed using the sixth positioning bolt. The L-shaped structure of the auxiliary positioning plate allows for better connection.

[0009] A placement base plate is installed on top of the mounting base plate, and a dustproof box is installed on top of the placement base plate. A connecting plate is rotatably connected above the dustproof box, and a shock-absorbing plate is installed on top of the connecting plate. A limit plate is installed on top of the shock-absorbing plate, and the limit plate is located below the auxiliary detection mechanism. Equally spaced movable sliders are slidably connected inside the limit plate. A detection clamping block is installed on one side of each movable slider. The limit plate has a placement cavity for placing a closure component. The closure component is placed inside the placement cavity, and multiple movable sliders are manually moved towards the center until the closure component is limited by the detection clamping block. At this time, the movable sliders are positioned and installed by the fourth positioning bolt to avoid equipment reset.

The detection clamping blocks and elastic sponge pads limit the position of the seal, while reducing direct contact... To prevent equipment damage caused by contact and extend the service life of the equipment, the dustproof box is internally connected to a rotating shaft, which in turn is internally connected to a first gear and a second gear. The second gear is located above the first gear, and a connecting rod is fixedly connected to the axis of the second gear.

The first drive motor rotates, driving the second bevel gear to rotate, which in turn drives the top rotating shaft to rotate. Under the limitation of the two limiting plates, this drives the top connecting plate. Orientation adjustment is performed to meet the angle and orientation requirements during testing, improving the flexibility of use in testing closed components. Fixed support plates are fixedly connected to both sides of the fixed frame. Second positioning bolts extending into the interior of the fixed frame are threaded into the interior of each fixed support plate.

The fixed support plates and mounting base plate are positioned and installed using the first positioning bolts, and the fixed support plates and fixed frame are positioned and installed using the second positioning bolts, thereby achieving a reinforced connection between the mounting base plate and the fixed frame.

[0012] In a preferred embodiment, the bottom of the mounting base is fixedly connected with equidistantly distributed support feet, and a field storage box is installed on the top of the mounting base and on one side of the fixing frame. The field storage box is used to store some of the equipment on site for easy access during use.

The control panel is used to control the operation of the first drive motor, the second drive motor, the laser sensor, the lighting panel, and the infrared sensor, thereby realizing unified management of the power equipment.

[0014] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0015] By setting up an installation base plate, placement base plate, shock absorber, and dustproof box, the equipment damage caused by direct contact is reduced, thereby extending the service life of the equipment. The operation of the second drive motor drives the first gear to rotate, which in turn causes the second gear meshing above the first gear to rotate. Under the limitation of the connecting rod and the limiting plate, the top connecting plate is driven to make a fine angle adjustment. The operation of the first drive motor drives the second bevel gear to rotate, which drives the top rotating shaft to rotate.

[0030] In this scheme, a base plate 2 is installed on top of the mounting base plate 1, and a dustproof box 4 is installed on top of the mounting base plate 2. A connecting plate 38 is rotatably connected above the dustproof box 4.

The sealing component is placed inside the placement cavity 32, and multiple movable sliders 34 are manually moved towards the center until the sealing component is limited by the detection clamping block 35. At this time, the movable sliders 34 are positioned and installed by the fourth positioning bolt 36 to avoid equipment reset.

[0031] Going a step further, such as Figures 1-4 As shown: In this scheme, the top of the limiting plate 31 and one side of the movable slider 34 are threaded with a third positioning bolt 33 extending into the interior of the shock-absorbing plate 3; the top of the movable slider 34 is threaded with a fourth positioning bolt 36 extending into the interior of the limiting plate 31; elastic sponge pads 37 are installed on the adjacent sides of multiple detection clamping blocks 35; fifth positioning bolts 56 extend from the outer side of the auxiliary positioning plate 55 into the interior of the movable slide plate 5; two symmetrically distributed limiting rods 59 extending into the top mounting guide rail 13 are installed on the outer side of the mounting block 51. After manually adjusting the position of the mounting block 51, the two limiting rods...

Under the limitation of the connecting rod 46 and the limiting plate 47, the top connecting plate 38 is driven to make a fine angle adjustment, which improves the flexibility of the use of the sealing component inspection.

[0033] In this design, a motor mounting base 21 is fixedly connected to the top of the base plate 2 and to one side of the dustproof box 4. A first drive motor 22 is fixedly connected to the top of the motor mounting base 21. The output end of the first drive motor 22 extends into the dustproof box 4 and is fixedly connected to a second bevel gear 43. A first bevel gear 42 is fixedly connected to the bottom of the rotating shaft 41. The second bevel gear 43 is located above the first bevel gear 42 and meshes with the first bevel gear 42. The first drive motor 22 rotates, driving the second bevel gear 43 to rotate, which in turn drives the rotating shaft 41 at the top to rotate. Under the limitation of the two limiting plates 47, the connecting plate 38 at the top is adjusted in orientation, which meets the requirements for angle and orientation during inspection and improves the flexibility of use in the inspection of the sealing component.

[0037] Working principle:

[0038] like Figures 1-5 As shown:

[0039] By setting up the mounting base plate 1, placement base plate 2, shock absorber plate 3, and dustproof box 4, when in use, open the control panel 18, and position and install the infrared sensor 57 and auxiliary positioning plate 55 using the sixth positioning bolt 58. The L-shaped structure of the auxiliary positioning plate 55 facilitates better connection. The limit plate 31 has an inner cavity 32 for placing the closure component. Place the closure component inside the inner cavity 32, and manually move multiple movable sliders 34 towards the center until the closure component is limited by the detection clamping block 35. At this time, the movable sliders 34 are positioned and installed using the fourth positioning bolt 36 to prevent the equipment from resetting.

[0040] After manually adjusting the position of the mounting block 51, the mounting block 51 and the top mounting guide rail 13 are positioned and installed using two limit rods 59 to prevent the equipment from moving on its own during actual testing. The auxiliary positioning plate 55 and the mounting block 51 are positioned and installed using the fifth positioning bolt 56, which facilitates the height adjustment of the infrared sensor 57 at the bottom of the auxiliary positioning plate 55.

[0041] The installation of the limiting plate 31 and the shock-absorbing plate 3 is reinforced by multiple third positioning bolts 33, which improves the stability of the equipment during the testing of the seal. The sealing component is limited by the testing clamping block 35 and the elastic sponge pad 37, which reduces the equipment damage caused by direct contact and thus extends the service life of the equipment.

[0042] The second drive motor 23 operates, driving the first gear 44 to rotate, which in turn causes the second gear 45, which is meshed above the first gear 44, to rotate. Under the limitation of the connecting rod 46 and the limiting plate 47, the connecting plate 38 at the top is driven to make a fine angle adjustment.

[0043] The first drive motor 22 rotates, driving the second bevel gear 43 to rotate, which in turn drives the top rotating shaft 41 to rotate. Under the limitation of the two limit plates 47, the top connecting plate 38 is driven to adjust its orientation, which meets the requirements for angle and orientation during inspection and improves the flexibility of use in the inspection of the sealing component.

[0044] The control panel 18 is used to control the operation of the first drive motor 22, the second drive motor 23, the laser sensor 53, the lighting panel 54, and the infrared sensor 57, thereby realizing unified management of the power equipment.

[0045] The on-site storage box 17 is used to store some of the equipment on-site for easy access. Multiple support feet 11 provide overall support, improving the stability of the equipment during placement. The first positioning bolt 15 of the mounting base plate 1 positions and installs the fixed support plate 14 and the mounting base plate 1, while the second positioning bolt 16 positions and installs the fixed support plate 14 and the fixed frame 12. This achieves a reinforced connection between the mounting base plate 1 and the fixed frame 12, reducing the degree of manual intervention, accelerating the overall testing efficiency, and meeting the needs of actual testing.
