Referring to fig. 1 to 3, the present utility model provides a lateral pressing assembly, which is applied in an airtight detection device, and includes a base 100, a movable seat 200, a plugging member 300, a pressure sensor 400, and a driver 500. Wherein the movable seat 200 is movably mounted on the base 100 along the front-rear direction; the blocking piece 300 is movably installed on the movable seat 200 along the front-back direction; the pressure sensor 400 is disposed between the movable seat 200 and the blocking piece 300, the pressure sensor 400 has a back end and a detection end which are disposed opposite to each other, the back end is mounted on the movable seat 200, and the detection end faces the blocking piece 300, so that the pressure sensor 400 generates pressure information when the blocking piece 300 moves backward to abut against the detection end; the driver 500 is disposed on the base 100 and is in driving connection with the movable seat 200.

In the technical scheme provided by the utility model, the shell 900 to be tested is positioned in front of the lateral jacking component, when the driver 500 drives the movable seat 200 to move forwards, the blocking piece 300 and the pressure sensor 400 are driven to move forwards synchronously, and when the front section of the blocking piece 300 is inserted into the structural hole of the shell 900 to be tested, the shell 900 to be tested applies a backward reaction force to the blocking piece 300, so that the blocking piece 300 moves backwards relative to the movable seat 200 and approaches and abuts against the detection end of the pressure sensor 400, and the pressure sensor 400 is triggered to perform pressure sensing, and the pressure information of the blocking piece 300 is obtained; by monitoring the pressure information of the plugging piece 300, the jacking pressure applied by the plugging piece 300 to the structural hole of the shell 900 to be tested can be accurately controlled in a proper range, so that good airtight plugging can be realized, and the structure of the shell 900 to be tested is not damaged.

In view of the above, the lateral pressing assembly is applied in an airtight detection apparatus. Specifically, the air tightness detecting device includes a platform 810, the platform 810 defines a detecting station, and the lateral pressing assembly may be located beside the detecting station, and for convenience of understanding, an example in which the detecting station is located in front of the lateral pressing assembly will be described. In addition, the platform 810 may also be positioned on other sides of the inspection station, such as in front of the inspection station.

Further, the air tightness detection device further comprises a carrier plate 820 which can be arranged in a translation mode along the front-back direction, and the carrier plate 820 can reciprocate between a waiting station and a detection station. When the carrier plate 820 is at the waiting station, the shell 900 to be tested is mounted on the carrier plate 820 in a manual operation or automatic operation mode such as a conveyor belt and a mechanical arm, so as to realize the feeding of the shell 900 to be tested. When the carrier plate 820 drives the housing 900 to be tested to move to the testing station, the lateral pressing assembly starts to work.

The movement of the carrier plate 820 may be driven by a translational drive mechanism 830. The translation driving mechanism 830 is implemented by, for example, a linear cylinder, or a combination of the motor 510 and a reversing assembly, where the reversing assembly may be a screw 520 nut assembly, a rack and pinion assembly, a linkage mechanism, or the like. In order to increase the stability of the reciprocating motion of the loading plate 820, one of the loading plate 820 and the platform 810 may be further provided with a guide rail, wherein the other one is provided with a guide groove, and the motion of the loading plate 820 is guided by the sliding fit of the guide rail and the guide groove.

While for a lateral pressing assembly:

the base 100 is mounted to the platform 810. It will be appreciated that the base 100 may be configured to be movably adjustable in a direction toward and away from the inspection station when the lateral jacking assembly is in a non-operational state. The direction approaching to and separating from the detection station may be a front-back direction or an up-down direction, so that the horizontal distance and the relative height between the blocking member 300 and the detection station in the initial state are adjustable. The adjustment manner may be various, for example, in an embodiment, one of the base 100 and the platform 810 is provided with an elongated hole extending longitudinally along the front-back direction or the up-down direction, or a plurality of adjustment holes arranged at intervals in sequence, and the other one is provided with a connecting hole, and the connecting hole is adjusted by a fastener to be connected with different parts of the elongated hole or different adjustment holes, so as to realize the position adjustment of the base 100 relative to the platform 810. And after the position adjustment is completed, the base 100 can be fixedly connected to the platform 810 by the fastener, so that the base 100 is prevented from sliding relative to the platform 810 in the working process of the lateral jacking assembly.

The movable base 200 is movably installed to the base 100 in the front-rear direction. The movement between the movable mount 200 and the base 100 may be a sliding fit. At this time, referring to fig. 4, in an embodiment, one of the joints between the movable base 200 and the base 100 may be provided with a sliding rail 110 extending in the front-rear direction, and the other one is provided with a sliding slot 220, where the sliding slot 220 is slidably engaged with the sliding rail 110. The sliding fit of the sliding rail 110 and the sliding groove 220 helps to provide accurate path guidance for the front-back movement of the movable seat 200 relative to the base 100, and helps to assist in the stable connection between the movable seat 200 and the base 100.

Alternatively, the movement between the movable base 200 and the base 100 may be a rolling fit. At this time, one of the joints between the movable seat 200 and the base 100 may be provided with a long groove extending in the front-rear direction, and the other one of the joints is rotatably provided with a roller, and the roller rolls in the long groove to drive the movable seat 200 to translate back and forth relative to the base 100. The rolling fit of the rollers and the long grooves is beneficial to further reducing friction loss during relative movement between the movable seat 200 and the base 100, so that the translation process of the movable seat 200 relative to the base 100 is smoother and more labor-saving.

The base 100 may further have a side plate erected behind the movable seat 200, and the side plate may stop the movable seat 200 moving backward to a limit position, so as to prevent the movable seat 200 from falling out of the base 100.

The blocking member 300 is generally elongated in the front-rear direction, for example, in a rod or pin shape. The cross-sectional shape of the closure 300 is adapted to the shape of the structural opening of the housing 900 to be tested, which is to be pressed. And in order to make the same closure 300 usable for different sizes of structural holes:

in one embodiment, the cross-sectional area of the occluding component 300 is tapered from front to back. The plugging member 300 may be, for example, configured as a conical shape with a gradually increasing diameter from front to back, so that by adjusting the plugging depth between the plugging member 300 and the structure hole, at least one section of the plugging member 300 may be adapted to the current structure hole size, so that the structure hole may be tightly plugged. The cross-sectional area is arranged to be progressively larger to provide a continuous, progressively larger variety of cross-sectional areas, for example, to provide a continuously increasing variety of diameters, to accommodate more size structural holes.

Alternatively, in an embodiment, the plugging member 300 is arranged in a multi-stage step shape with a cross-sectional area gradually increasing from front to back, so as to form a plurality of step surfaces with gradually increasing cross-sectional area. As such, the occluding component 300 provides a limited number of cross-sectional areas to match the size of a limited variety of structural holes. However, since each step provides a step surface of a different size, when the blocking member 300 and the structural hole are inserted into the corresponding step, the step surface formed between the step and the subsequent step can completely cover the gap between the structural hole and the blocking member 300, which helps to enhance the sealing effect of the blocking member 300 on the structural hole.

Furthermore, the closure 300 may be provided in a plurality. Based on this, the lateral jacking assembly further includes a mounting plate 700, the mounting plate 700 is movably mounted to the movable seat 200 in the front-rear direction, and the pressure sensor 400 is disposed between the movable seat 200 and the mounting plate 700; the rear ends of the plurality of blocking members 300 are connected to the mounting plate 700.

When the to-be-detected shell 900 with specific specifications corresponds, each plugging piece 300 can be simultaneously used for plugging, at this time, the arrangement mode of the plugging pieces 300 is consistent with the arrangement mode of the corresponding structure holes on the to-be-detected shell 900, so that when the movable seat 200 drives the mounting plate 700 to move forward, the plugging between all the plugging pieces 300 and the structure holes can be synchronously realized.

Or further, each plugging piece 300 can be telescopic back and forth relative to the mounting plate 700, for example, a mounting groove or a mounting hole is formed in the mounting plate 700 corresponding to each plugging piece 300, at least part of the plugging piece 300 is accommodated in the mounting groove or penetrates out of the mounting hole backward, and the plugging piece 300 can be telescopic back and forth relative to the mounting groove, so that the protruding length of the plugging piece 300 protruding from the front surface of the mounting plate 700 can be adjusted, and thus, when the structural hole of the shell 900 to be tested with one specification is plugged, the corresponding plugging piece 300 can be extended forward in a corresponding arrangement mode, the rest plugging pieces 300 are retracted backward, and the lateral pressing assembly can be adapted to the shell 900 to be tested with multiple specifications.

Of course, a plurality of mounting positions may be reserved on the mounting plate 700, and each mounting position may be detachably connected to one plugging member 300, so that the current lateral pressing assembly may be adapted to the housing 900 to be tested in the current specification by mounting the plugging member 300 in the required number and the required direction to the corresponding mounting position.

Further, in an embodiment, one of the movable seat 200 and the mounting plate 700 extends in the front-rear direction to form a guide rod 710, and the other extends in the front-rear direction to form a guide hole 210, and the guide rod 710 is slidably engaged with the guide hole 210. The guide rods 710 and the guide holes 210 are arranged in groups, and can be arranged into a plurality of groups according to actual needs, and the guide rods 710 and the guide holes 210 in the plurality of groups can be dispersed in all positions between the mounting plate 700 and the movable seat 200, for example, the guide rods are symmetrical about the mass center or the center of the mounting plate 700, so that the front-back movement of the mounting plate 700 relative to the movable seat 200 can be balanced and stable.

Based on any of the above embodiments, when the pressure sensor 400 is installed between the mounting plate 700 and the movable seat 200, the back end of the pressure sensor 400 may be specifically set to be connected to the front surface of the movable seat 200, and a certain initial avoidance space is reserved between the detection end of the pressure sensor 400 and the mounting plate 700, so as to avoid the collision of the detection end by the mounting plate 700 in the non-working state. Alternatively, the detection end of the pressure sensor 400 may be specifically connected to the rear surface of the mounting plate 700, and a certain initial avoidance space is reserved between the rear end of the pressure sensor 400 and the movable seat 200.

Further, referring to fig. 5, in an embodiment, the back end of the pressure sensor 400 is floatably mounted to the movable seat 200 by an elastic member 600. In this case, the elastic member 600 may be a rubber block or the like, or a spring member, for example. The floating arrangement of the pressure sensor 400 between the mounting plate 700 and the movable base 200 allows the pressure experienced by the pressure sensor 400 to be flexibly relaxed when the closure member 300 is moved rearward relative to the movable base 200 under the reactive force of the housing 900 to be tested.

Specifically, in an embodiment, the rear end of the elastic member 600 is fixedly connected to the movable seat 200, and an annular clamping groove 610 is formed in the sidewall of the elastic member 600 along the circumferential direction thereof. A clamping protrusion 410 is convexly arranged at the lateral side of the back end of the pressure sensor 400, and the clamping protrusion 410 is clamped and fixed with the annular clamping groove 61. The annular clamping groove 610 can provide a clamping and fixing space for the clamping protrusion 410 in the whole circumference, thereby being more convenient for installation and adjustment.

The pressure sensor 400 may be provided as one or at least two. When at least two pressure sensors 400 are provided, the number of the drivers 500 may correspond to the number of the pressure sensors 400, and perform corresponding actions according to the sensing data fed back by the corresponding pressure sensors 400. Specifically, for example, in one embodiment, the driver 500 is a servo motor, and when the pressure sensors of each group detect a predetermined pressure, the corresponding servo motor stops moving and maintains the pressure.

In addition, in an embodiment, the driver 500 is a motor 510, and the movable seat 200 is provided with a screw hole 230 along the front-rear direction; the lateral pressing assembly further comprises a screw 520, wherein the screw 520 is connected with the motor 510 and is in threaded fit with the screw hole 230. The motor 510 may be fixed with respect to the base 100, and a rotation output shaft of the motor 510 extends in a front-rear direction and is coupled with the screw 520 through, for example, a coupling. When the motor 510 is started, the screw rod is driven to rotate along the front-rear axis, and is screwed with the screw hole 230, so that the movable seat 200 is driven to translate along the length direction of the screw rod 520, namely, front-rear direction. Thus, not only the front and back movement of the movable seat 200 can be driven, but also the front and back movement stroke amount of the movable seat 200 can be adjusted by setting the length of the screw 520, so that the movable seat is more practical.

The foregoing description is only of the preferred embodiments of the present utility model and is not intended to limit the scope of the utility model, and all equivalent structural changes made by the description of the present utility model and the accompanying drawings or direct/indirect application in other related technical fields are included in the scope of the utility model.
