Detailed Description

The embodiment of the invention discloses a pressure standard component device, which is used for meeting the requirements of pressure maintaining or checking and testing without pressure.

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Referring to fig. 1-2, fig. 1 is a schematic structural diagram of a pressure standard device according to an embodiment of the present invention; fig. 2 is another view of fig. 1.

In one embodiment, the invention provides a pressure standard device comprising a support body 2, a standard 1 and a spacing member.

Wherein the bottom end of the support body 2 has an opening. The support body 2 is a carrier for the standard 1 for integrating a plurality of standards 1. When the pressure testing device works, the supporting main body 2 can be driven to move by driving components such as a motor and the like so as to apply pressure to a workpiece to perform pressure maintaining or checking and testing. The specific structure of the support body 2 may not be limited, and may be configured as a housing, a frame structure, or the like. The bottom end of the support body 2 has an opening to facilitate the extension of the standard 1 into interaction with the workpiece.

The plurality of standard components 1 are slidably mounted in the support main body 2 and are sequentially arranged along the sliding direction, and the bottom ends of the standard components 1 located at the lowest position in the sliding direction are extended from the openings to be used as action ends. The respective standards 1 are arranged in this order in the up-down direction with the sliding direction as the up-down direction. The acting end, namely the standard component 1 directly acts on one end of the workpiece for pressure maintaining or checking and testing. Here, a plurality of the present invention means two or more. The standard component 1 is slidably mounted in the support body 2, and when the standard component 1 is not limited by the limiting part, the standard component 1 can slide up and down along the support body 2, and the lowest standard component 1 cannot be separated from the support body 2. For example, the width of the top end of the lowermost module 1 is set to be larger than the width of the opening, so that it is caught in the opening. Of course, the lowermost module 1 should be able to move upwards from the opening within a certain range, and in operation, the lowermost module 1 is moved upwards relative to the support body 2 by the downward pressure of the support body 2, and is no longer supported by the support body 2, so that the pressure is applied to the workpiece completely.

The limiting parts are respectively arranged corresponding to each standard component 1 above, and are used for limiting the corresponding standard component 1 at a position spaced from the adjacent standard component 1, or eliminating the limiting to enable the corresponding standard component 1 to be overlapped with the standard component 1 below. Here, each of the upper standard components 1 refers to a plurality of standard components 1 arranged in sequence in the vertical direction, and each of the standard components 1 located above the lowermost standard component 1 is provided with a stopper member correspondingly, but the lowermost standard component 1 is not limited. In the case where the support body 2 can restrict the lowermost standard 1 to prevent it from coming off, it is not necessary to provide a restricting member thereto. Of course, the lowermost standard 1 may be provided with a stopper member as needed.

The stopper member is provided to perform a stopper function on the corresponding standard component 1, and the stopper member is operated to switch between a stopper state and a stopper release state. The standard component 1 is spaced from the adjacent standard component 1 under the limiting action of the corresponding limiting part, the specific spacing can be set according to requirements, and when the standard component 1 below is in pressure application work, the standard component 1 does not act due to the spacing. When the standard component 1 is not limited by the corresponding limiting part, the standard component 1 can be overlapped with the lower standard component 1 under the action of self gravity, and when the lower standard component 1 applies pressure to work, the standard component 1 overlapped with the lower standard component applies pressure together to act together. The specific structure of the limiting part can adopt a manipulator, a telescopic limiting bulge and the like, and is not limited in detail here.

With the pressure standard device provided by the invention, the support body 2 is used as a carrier of the standard 1, and each standard 1 is installed in a sliding way. The number of the force application standard components 1 can be selected according to the different pressure values required by pressure maintaining or checking and testing. If a smaller pressure is needed, each upper standard component 1 can be limited by the limiting component, so that two adjacent standard components 1 are arranged at intervals, and the lowest standard component 1 can be used as a force application component for pressure loading. When a large pressure is needed, the pressure loading can be carried out under the combined action of increasing the number of the working standard parts 1, namely releasing the limit of one or more standard parts 1 above and enabling the working standard parts to slide downwards along the support main body 2 under the action of gravity to be overlapped with the standard part 1 at the lowest. In conclusion, through the structure, the increase and decrease of the standard component 1 can be conveniently carried out, so that the requirements of different pressure maintaining or checking and testing are met, and the problem that the use of the standard component 1 with a single specification is limited is solved.

Specifically, the limiting part is a clamping jaw 3, through holes are formed in the supporting body 2 corresponding to the clamping jaws 3, the corresponding standard part 1 is limited in the inward clamping state of the clamping jaws 3, and the limitation on the standard part 1 is relieved when the clamping jaws are loosened outwards. That is, through holes are formed in the supporting body 2 corresponding to the standard parts 1 above, the clamping jaws 3 can extend into the through holes to limit the standard parts 1, specifically, the clamping jaws 3 can clamp the standard parts 1 through the matching of the clamping jaws 3 and the standard parts 1, or the clamping jaws 3 can be set to limit the standard parts 1 to move downwards relative to the supporting body 2, so that when the supporting body 2 is loaded and moves upwards, the standard parts 1 can keep intervals with the standard parts 1 below due to the limit of the clamping jaws 3. When the limit is required to be cancelled, the clamping jaw 3 is loosened outwards, the limit on the standard component 1 is cancelled, and the standard component 1 can fall under the action of the gravity of the standard component 1 and abut against the standard component 1 below. The limiting part adopts the clamping jaw 3, so that the structure is simple and the control is convenient.

Specifically, telescopic cylinders are respectively arranged in cooperation with the clamping jaws 3 and control the clamping jaws 3 to loosen or clamp. Through the setting of telescoping cylinder, can drive clamping jaw 3 inwards to remove in order to step up automatically, perhaps outwards remove in order to loosen. The telescopic cylinder can be a cylinder, and can also be a telescopic driving part such as a hydraulic cylinder and the like according to needs.

Further, the top of the standard 1 corresponding to each clamping jaw 3 is provided with a flange, and the clamping jaws 3 can be blocked under the flange when clamped inwards to limit the downward movement of the standard 1. Through the setting of flange, when clamping jaw 3 inwards steps up, the card hinders in the flange below, so when supporting body 2 shifts up, clamping jaw 3 can restrict the relative downward shifting that supports body 2 of standard component 1 when clamping jaw 3 offsets back with the flange to drive standard component 1 and shift up together along with supporting body 2. The flange is matched with the clamping jaw 3, the structure is simple, and the complex structure improvement on the standard component 1 is not needed. When the stopper is configured to be grabbed by a robot or the like, the standard 1 may not be provided with a flange.

In the above embodiments, the top of the standard component 1 located at the lowest position in the sliding direction has a flange, and the flange can abut against the periphery of the opening to prevent the lowest standard component 1 from falling out. That is to the standard component 1 of the lowest, its top also has the flange, through flange and supporting body 2 cooperation, with standard component 1 spacing can not deviate from in supporting body 2, and because the flange is located the top, then the bottom of standard component 1 can be by the opening protrusion under self action of gravity to be convenient for carry out pressure loading. Specifically, the appearance structures of the standard parts 1 are the same, namely the top of each standard part 1 is provided with a flange, so that when the pressure standard part device is assembled, the upper and lower installation positions of the standard parts 1 do not need to be distinguished, and the assembly is more convenient.

When pressure maintaining or checking and testing is performed, specifically, taking two standard components 1 participating in loading as an example, the bottom end of the standard component 1 at the bottom is pressed down by the supporting main body 2 to be in contact with a workpiece to become an acting end, and the acting end moves upwards relative to the supporting main body 2, so that the supporting effect of the supporting main body 2 is not exerted. And the second standard component 1 is positioned above the second standard component 1 adjacent to the lowest standard component 1, and the limiting part releases the limiting effect on the second standard component 1, so that the second standard component 1 moves downwards under the self gravity to abut against the lowest standard component 1 to realize the combined action. In this state, the second standard component 1 should have a gap from the upper standard component 1, and the gap can be specifically controlled by the pressing distance of the supporting body 2, so as to ensure the number of the actually working standard components 1.

In particular, it is possible for the support body 2 to be a cylinder, such as a cylinder. The hollow part of the cylinder body is used for placing each standard component 1, and a through hole for the clamping jaw 3 to extend into is arranged on the side wall of the cylinder body. The cylinder structure can be used as a carrier of the standard component 1, and can play a good dustproof and protection role in the standard component 1. The support body 2 is not limited to the cylindrical body, and other carriers such as a bracket may be used as necessary.

For the shape of the standard 1, the structural arrangement of a conventional standard 1 can be used. Specifically, each standard 1 includes a conical main body portion, and the axes of the conical main body portions are collinear. Adopt circular cone main part, then the one end at its pointed end can be used as the effect end, can realize the pressurization in accurate position to satisfy different pressurize goods pressure test demands. In the case where the standard 1 is provided with a flange at its top end, a boss, preferably a circular truncated cone, is attached to the circular top surface of the conical body portion to form the flange. It should be noted that the axes of the conical body portions are collinear, which means that the conical body portions of the respective standards 1 are collinear in the sliding direction, so that when the upper and lower standards 1 are stacked for common loading, effective and accurate loading of the pressure of the standards 1 is ensured.

In addition to the above embodiments, in a state where each stopper member restricts the corresponding standard cell 1, the distances between the adjacent standard cells 1 are equal or unequal. The distances between the adjacent standard parts 1 are equal, so that the clamping jaws 3 and other limiting parts can be conveniently arranged. And the distance between the adjacent standard components 1 is equal, so that the moving distance of the support main body 2 is conveniently controlled during loading, and the number of the actually participating working standard components 1 is equal to the number of the target working standard components 1 controlled by the limiting component. According to the requirement, under the state that each limiting component limits the corresponding standard component 1, the distance between the adjacent standard components 1 can be unequal, and the stroke of each standard component is controlled correspondingly.

In the above embodiments, the weights of the plurality of standard members 1 are all different or all the same or the weights of some of the standard members 1 are the same. Pressure standard component device in this application can be convenient carry out the increase and decrease of standard component 1 to satisfy the demand that does not need pressure pressurize or check-up and test, consequently can the same to its weight of each standard component 1, also can be different, as required set up can. When the weights of the standard parts 1 are different, the number of the standard parts 1 involved in loading is increased or decreased, so that diversified loading pressures can be realized.

For a more clear description of the present solution, three standards 1 are provided as an example in the following.

The first standard member 11, the second standard member 12, and the third standard member 13 are provided in this order from the bottom to the top in the sliding direction. The thickness of each standard component 1 can be 40mm, the distance between adjacent standard components 1 is 10mm when each limiting component limits the corresponding standard component 1, and the height of the part of the first standard component 11 extending out of the opening is 27 mm.

When a small pressure is needed, the limiting parts corresponding to the second standard component 12 and the third standard component 13 limit the two respectively, and the support main body 2 is controlled to be pressed downwards, and the pressing depth cannot be larger than 10mm (such as 6mm) after the first standard component 11 contacts the product, so as to avoid contacting the second standard component 12.

When a larger pressure is needed, the limiting part corresponding to the third standard part 13 still limits the position of the third standard part, the limiting part clamping the second standard part 12 releases the limit of the second standard part 12, the second standard part 12 and the first standard part 11 are overlapped and pressed downwards together, the pressing depth is larger than 10mm and smaller than 20mm (such as 16mm) after the pressing is contacted with a product, and the second standard part 12 is prevented from touching the third standard part 13. When the limiting part adopts the clamping jaw 3 and is matched with the flange on the standard part 1 for limiting, the clamping jaw 3 for clamping the second standard part 12 extends inwards to clamp at the moment of finishing pressing, so that the clamping jaw 3 can be used for clamping the second standard part 12 in the process of driving the supporting main body 2 to ascend by the motor.

When a larger pressure is needed, the limiting parts corresponding to the second standard part 12 and the third standard part 13 respectively relieve the limitation of the first standard part 11, the second standard part 12 and the third standard part 13, so that the first standard part 11, the second standard part 12 and the third standard part 13 are superposed together and pressed down to contact with a product, and the pressing depth is more than 20mm and less than 27mm (for example, 24mm) to avoid excessive pressing down, when the limiting parts adopt the clamping jaws 3 and are matched with the flanges on the standard parts 1 for limiting, the clamping jaws 3 clamping the second standard part 12 and the third standard part 13 at the moment of finishing pressing are respectively stretched inwards to clamp, and thus each clamping jaw 3 can clamp the second standard part 12 and the third standard part 13 in the process of driving the support main body 2 to ascend by the motor.

Based on the pressure standard device provided in the above embodiment, the present invention further provides a pressure device, which includes any one of the pressure standard devices in the above embodiments and a driving device for driving the support body 2 to move for pressing.
