Description

Technical Field

[0001] This utility model relates to the technical field of mating component sealing tester, specifically an improved mating component sealing tester. Background Technology

[0002] The component sealing tester is a device that uses a pressure reduction method and different tooling to test the sealing performance of plunger components, nozzle components, and oil outlet valve components.

[0003] Existing component sealing testing machines include a testing machine body, which has a worktable and a clamping fixture and a control panel mounted on it. The clamping fixture is controlled by a foot pedal control switch installed on the ground. The control panel is located on the front side of the testing machine body. The worktable has a recessed structure. This type of component sealing testing machine requires the testing personnel to operate while standing, which is inconvenient. In addition, the worktable occupies a large space and cannot make good use of the space. Utility Model Content

[0004] To address the technical problems existing in the background art, this utility model provides an improved mating component sealing performance testing machine.

[0005] The technical solution of this utility model is as follows: An improved mating component sealing performance testing machine includes a testing machine body disposed on a reference surface. The testing machine body includes a clamping fixture and a control assembly. An extended worktable is provided on the front side of the testing machine body. The worktable is located in the middle of the testing machine body. The clamping fixture is disposed on the worktable, and the control assembly is located on the front side of the testing machine body. The front side of the main body of the testing machine is provided with an extended base plate. The base plate is located at the lower end of the front side. The extension direction of the base plate is consistent with the extension direction of the worktable. The clamping fixture includes the fixture body and the foot switch connected to it. The foot switch is set on the base plate. The foot switch and the base plate are detachably connected by a connector and are located on one side directly below the fixture body. The upper surface of the base plate is an inclined surface, and the inclination direction is downward along its width from the side closest to the front side.

[0006] A workbench is set on the front side of the main body of the testing machine for installing the clamping fixture of the component sealing testing machine. The clamping fixture is used to clamp the component to be tested on the workbench. Both the workbench and the base plate extend outward, and the space between them allows the operator to sit in front of the main body of the testing machine to perform component testing operations. The foot switch is located on the base plate, which makes it convenient for the operator to operate the clamping fixture in a seated position as well as when standing. It will not obstruct the operator's movement. At the same time, the extended workbench can increase the operating space and reduce space waste.

[0007] Preferably, the lower surface, front side, and upper surface of the base plate of the worktable form a semi-enclosed knee cavity.

[0008] The horizontal direction of the front side is its length direction, and the length direction of the worktable is consistent with the length direction of the front side. The clamping device is located on the inner side above the worktable. In order to facilitate the operator to operate the clamping device in a seated position, the width of the worktable is set to be greater than the width of the base plate.

[0009] The base plate has the following structure: its width is 2 / 4 to 3 / 4 of the width of the workbench, and its width is greater than the longest length of the foot pedal surface of the foot switch. The base plate is shorter than the workbench, which makes it easier for the operator to approach the clamping fixture to clamp the parts when seated. This avoids the inconvenience of operating the clamping fixture due to the base plate being the same width as the workbench.

[0010] The angle of inclination of the inclined surface is 5-15° between the extension line of the plane containing the inclined surface of the base plate and the reference plane. This can reduce the pressure points on the operator's feet when not operating the foot switch, avoiding discomfort caused by prolonged pressure. The inclined foot pedal can provide a larger contact area, allowing the user's feet to be placed more comfortably and reducing fatigue during long-term work.

[0011] To facilitate better control of the clamping fixture by the operator in a seated position, the vertical distance between the upper surface of the workbench and the inclined surface of the base plate is 60-80 cm, and the vertical distance between the horizontal plane where the lowest position of the inclined surface is located and the horizontal plane where the reference plane is located is less than 10 cm.

[0012] The outer edge of the workbench is provided with a stop bar that is arranged along its side length. The stop bar includes an integrally formed U-shaped plate and a U-shaped inner liner. The U-shaped plate is located on the upper surface of the outer edge of the workbench, and the U-shaped inner liner is located on the inner side of the workbench.

[0013] The cross-section of the baffle is an inverted L-shaped structure.

[0014] The beneficial effects of this utility model are as follows: Both the workbench and the base plate extend outwards, and the semi-enclosed knee cavity allows the operator to sit in front of the main body of the testing machine to perform part testing operations without having to stand for a long time to perform part testing. The foot switch is located on the base plate, which makes it convenient for operators to operate the clamping fixture while seated or standing. It does not obstruct the operator's movement. At the same time, the extended worktable can increase the operating space and reduce space waste. The angle between the extension line of the inclined plane of the base plate and the reference plane is 5-15°, which can reduce the pressure points on the operator's feet when not operating the foot switch, avoid discomfort caused by long-term pressure, and the inclined foot pedal can provide a larger contact area, allowing the user's feet to be placed more comfortably, reducing fatigue during long-term work, and also making it easier to install the foot switch. The outer edge of the workbench is usually integrally formed with the workbench. The U-shaped inner liner is set on the inner side of the workbench and cooperates with the inner side of the U-shaped plate. It can protect the outer edge of the workbench and prevent the workbench from being bumped and worn when the workbench is placed or the workpiece is moved for a long time. In this embodiment, the stop bar is detachably connected to the workbench by several bolts. After the stop bar is worn by collision, the bolts can be removed and the stop bar can be replaced directly without replacing the entire workbench. Attached Figure Description

[0016] Example 1 See Figure 1 and Figure 2 As shown, an improved mating component sealing performance testing machine includes a testing machine body 1 set on a reference surface. The testing machine body 1 includes a clamping fixture 2 and a control component 3. The control component 3 includes a display screen and a control module electrically connected to it. The control module is installed inside the testing machine body 1. An extended worktable 4 is provided on the front side 11 of the testing machine body 1. The worktable 4 is located in the middle of the testing machine body 1. The clamping fixture 2 is set on the worktable 4, and the control component 3 is located on the front side 11 of the testing machine body 1, with the clamping fixture 2 located in front of the control component 3.

[0017] Because the existing technology has the display screen located on the front side 11 of the detection body, while the clamping mechanism is located inside the detection body, when clamping or adjusting the parts on the clamping fixture 2, it is too close to the display screen, and the operator has a large tilt angle with the display screen, which affects the viewing of the data on the display screen. Therefore, in this embodiment, the clamping fixture 2 is located in front of the display screen, and the clamping fixture 2 and the control component 3 are arranged along the length of the worktable 4. The vertical distance between the clamping fixture 2 and the control component 3 along the horizontal plane is 10-20 cm, which makes it convenient to view the data on the display screen when clamping or adjusting the parts on the clamping fixture 2, and facilitates the operation of the clamping fixture 2.

[0018] See Figure 3 As shown, a baffle 6 is provided along the outer edge of the upper surface of the workbench 4. The baffle 6 includes an integrally formed U-shaped plate 61 and a U-shaped inner liner 62. The U-shaped plate 61 is located on the upper end face of the outer edge of the workbench, and the U-shaped inner liner 62 is located on the inner side of the workbench. The cross-section of the baffle 6 is an inverted L-shaped structure. The baffle 6 serves to prevent the devices used for testing within the workbench 4 from falling off, and also to prevent leakage and splashing of the gas or testing liquid used during component testing. The height of the baffle 6 is 5-15 cm, and the baffle 6 can be made of transparent material for easy observation of the components. It should be noted that the outer edge of the workbench 4 is usually integrally formed with the workbench. The U-shaped inner liner 62 is set on the inner side of the workbench and cooperates with the inner side of the U-shaped plate 61. It can protect the outer edge of the workbench 4 and prevent the workbench 4 from being bumped and worn when the workbench is placed or the workpiece to be tested is moved for a long time. In this embodiment, the stop bar 6 is detachably connected to the workbench by several bolts. After the stop bar 6 is worn by collision, the bolts can be removed and the stop bar 6 can be replaced directly without replacing the entire workbench 4.

[0019] See Figure 1 and Figure 2 As shown, the front side 11 of the main body 1 of the testing machine is provided with an extended base plate 5. The base plate 5 is located at the lower end of the front side 11, and the extension direction of the base plate 5 is consistent with the extension direction of the worktable 4. The clamping fixture 2 includes a fixture body 21 and a foot switch 22 connected to it. The foot switch 22 is set on the base plate 5 and is detachably connected to the base plate 5 through a connector, and is located on one side directly below the fixture body 21. The upper surface of the base plate 5 is an inclined surface 51, and the inclination direction is inclined downward along its width direction from the side near the front side 11.

[0020] To facilitate the operation of the testing machine by the operator sitting in front of the testing machine body, so that the testing of the parts does not require standing for a long time, the lower surface of the workbench 4, the front side 44 and the upper surface of the base plate 5 form a semi-enclosed knee cavity.

[0021] The tilt angle of the inclined surface 51 is 5-15°, with the extension line of the plane containing the inclined surface 51 of the base plate 5 forming an angle with the reference plane. This reduces the pressure points on the operator's feet when not operating the foot switch 22, avoiding discomfort caused by prolonged pressure. The tilted foot pedal provides a larger contact area, allowing the user's feet to rest more comfortably and reducing fatigue during long-term work. To facilitate better operation of the clamping fixture 2 by the operator in a seated position, the vertical distance between the upper surface of the workbench 4 and the inclined surface 51 of the base plate 5 is 60-80 cm, and the vertical distance between the horizontal plane containing the lowest point of the inclined surface 51 and the horizontal plane containing the reference plane is less than 10 cm.

[0022] The transverse direction of the front side 11 is its length direction. The length direction of the worktable 4 is consistent with the length direction of the front side 11. The clamping device is located on the inner side above the worktable 4. To facilitate the operator's operation of the clamping device while seated, the width of the worktable 4 is greater than the width of the base plate 5. The structure of the base plate 5 is such that its width is 2 / 4 to 3 / 4 of the width of the worktable 4, and its width is greater than the longest length of the foot pedal surface of the foot switch 22. The width of the base plate 5 is shorter than that of the worktable 4, which makes it easier for the operator to approach the further clamping fixture 2 to clamp the device while seated, and avoids the inconvenience of operating the clamping fixture 2 due to the same width of the base plate 5 as the worktable 4.

[0023] A workbench 4 is provided on the front side 11 of the main body 1 of the testing machine for mounting the clamping fixture 2 of the mating part sealing tester. The clamping fixture 2 includes a clamping cylinder and a pressing component connected to the output end of the clamping cylinder. The clamping cylinder is a pneumatic hydraulic pump. The clamping cylinder and the pressing component are existing technologies. The electrical connection between the clamping fixture 2 and the foot switch 22 is also existing technology and is not shown in the figure. The main body 1 of the testing machine can be a floor-standing air tightness testing device from Ruixinlai or a cabinet-type air tightness testing device from Longhan Technology, etc. For ease of understanding, the connection relationship between the clamping fixture 2 and the control component 3 of the main body 1 of the testing machine is as follows (all of the following are existing technologies): The fixture body 21 is fixed to the upper surface of the workbench 4 by bolts, and its internal pneumatic hydraulic pump is connected to the fixture of the pair to be tested through a high-pressure oil pipe; the foot switch 22 is connected to the PLC control cabinet inside the main body 1 of the testing machine through its own connecting cable, with the industrial control computer as the host computer, responsible for parameter setting, data storage and display; and the PLC as the slave computer, responsible for executing precise logic and timing control. When the operator presses the foot switch 22, the switch sends a digital input signal to the PLC; after receiving this signal, the PLC, according to the preset program of the industrial control computer, first controls the electromagnetic pilot valve of the clamping cylinder to operate, driving the cylinder to press down and lock the pair. Subsequently, the PLC-controlled air intake solenoid valve opens, initiating the detection process. In this embodiment, the display screen of the control component 3 is connected to the industrial computer via a data cable, displaying the system pressure value and timing information collected by the PLC from the pressure sensor in real time. Since it is arranged side by side with the clamping fixture 2 along the length of the workbench, it ensures that the operator's line of sight can be kept basically parallel to the display screen when operating the fixture, and the reading can be clearly obtained without frequently adjusting the head angle.
