Description

Technical Field

[0001] The utility model relates to the technical field of rapid assembly, in particular to a quick-disassembly mechanism for detecting tooling. Background Art

[0002] A pressure sensor is a device or component that senses pressure signals and converts them into a usable electrical output signal according to certain rules. Pressure sensors typically consist of a pressure-sensitive element and a signal processing unit. Depending on the test pressure type, pressure sensors can be divided into gauge pressure sensors, differential pressure sensors, and absolute pressure sensors.

[0003] Figure 1 FIG. 1 shows a schematic diagram of the three-dimensional structure of a certain type of pressure sensor in the prior art. Figure 2 for Figure 1 In the cross-sectional structural diagram, 102 represents the pressure interface of the pressure sensor, 103 represents the cable plug of the pressure sensor, and 101 represents the adapter part of the pressure sensor. The adapter part is formed by the sealed connection between the pressure interface and the cable plug, and a cavity for storing circuit boards, chips, etc. is provided inside the adapter part. When in use, the external fluid medium flows into the cavity through the pressure interface and acts on the chip, etc. The cable plug is used to be plugged into the power supply to supply power to the chip, etc. During the production process of the pressure sensor, the sealing of the cavity of the adapter part is generally tested to prevent the fluid medium from entering the cavity when the pressure sensor is used, which causes inaccurate measured results.

[0004] After searching, the patent document with authorization announcement number CN216669115U discloses: a pressure sensor detection device, which includes a body, an air compressor, an air tank and a standard sensor, and also includes a chassis, the top of the chassis is fixed to the body, the interior of the chassis is provided with an air tank extending to the top of the chassis, the top of the air tank is embedded with a standard sensor, the air compressor is fixed to the chassis and the output end is connected to the air tank, the outside of the air tank is provided with an exhaust pipe extending to the outside of the chassis, the outside of the exhaust pipe is provided with a control valve, the top of the chassis is provided with a pressing mechanism fixed to the right side of the body, the top of the air tank is embedded with a mounting seat located below the pressing mechanism, the top of the body is fixed with an oscilloscope, and the bottom of the inner wall of the air tank is fixed with an acoustic emission transducer.

[0005] The above-mentioned detection device is achieved by pre-setting a standard pressure sensor on the body, then setting the pressure sensor to be tested on the body, and then simultaneously passing air of the same pressure into the pressure interfaces of the two and observing and comparing the readings of the two on the body. Based on the readings of the standard pressure sensor, it is judged whether the pressure sensor to be tested is qualified.

[0006] However, during long-term testing, the standard pressure sensor will be damaged under multiple intermittent high-pressure conditions. If this is not discovered in time, the pressure sensor that has passed the test by comparison will have major flaws, resulting in an increased defective rate. If the standard pressure sensor is replaced periodically, the testing cost will increase.

[0007] Based on the inconvenience of the above-mentioned detection method, technicians have proposed a detection method for closing the mold using the upper mold and the lower mold. When in use, the upper mold and the lower mold are respectively installed on the corresponding mold base. However, the installation of the upper mold and the lower mold on the corresponding mold base is usually achieved by using a plurality of conventional fastening bolts. This installation method requires multiple turns of tightening or loosening during disassembly, which makes the mold change time longer and reduces the detection efficiency. In addition, the upper mold and the upper mold base are connected longitudinally. In the process of fastening the upper mold with the fastening bolts, the upper mold will have a downward movement tendency on the upper mold base. The existence of this tendency can easily cause the external thread of the fastening bolt and the internal thread matching it to be damaged and jammed, which will further prolong the mold change time.

[0008] Based on this, we propose a quick-release mechanism for inspection tooling to solve the above problems. Utility Model Content

DETAILED DESCRIPTION

[0045] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0046] Example 1:

[0047] like Figure 3-Figure 15As shown, a detection tool for a pressure sensor includes a cabinet 14, an upper mold base 3 is movably provided on the top of the cabinet 14, a lower mold base 1 is fixedly provided on the bottom of the cabinet 14, and an upper mold 4 is provided on the upper mold base 3, and a lower mold 2 is provided on the lower mold base 1. A driving member 15 is also provided on the top of the cabinet 14, and the execution end of the driving member 15 is fixedly connected to the upper mold base 3, so that the driving member 15 can drive the upper mold 4 to approach the lower mold 2 below until the upper mold 3 and the lower mold 2 are in a closed mold state.

[0048] The lower die 2 is provided with a first blind hole 5, and the opening of the first blind hole 5 faces upwards. The upper die 4 is provided with a second blind hole 6, and the opening of the second blind hole 6 faces downwards. The lower die 2 is provided with a receiving groove 8 at the outer position of the first blind hole 5, and sealing rings are provided at the end positions of the receiving groove 8 and the first blind hole 5. Before testing, the upper die 4 is located above the lower die 2, and the upper die 4 and the lower die 2 are in the open state. This state can be determined by the Figure 3 、 Figure 5 and Figure 8 To represent, during the test, first insert the pressure interface 102 of the pressure sensor to be tested into the first blind hole 5, and then use the driving member 15 to drive the upper mold base 3 and the upper mold 4 to move downward until the second blind hole 6 is sleeved on the cable plug 103 of the pressure sensor and the adapter 101, and then drive the upper mold 4 downward. In this process, since the hole shoulder 7 is provided on the inner side wall of the second blind hole 6, the hole shoulder 7 inside the second blind hole 6 can apply a downward pressing force to the cable plug 103 during the downward process of the second blind hole 6, thereby making the bottom of the adapter 101 and the opening of the first blind hole 5 aligned. The sealing ring of the upper mold 4 contacts with the sealing ring, so that the first blind hole 5 is blocked and sealed; at the same time, the downward movement of the upper mold 4 will drive the open end of the second blind hole 6 to press the sealing ring in the accommodating groove 8. When the upper mold 4 moves to the specified position and is in the mold closing state with the lower mold 2, the adapter 101 will block and seal the first blind hole 5, and the accommodating groove 8 will block and seal the second blind hole 6, that is, the pressure interface 102 of the pressure sensor is located in the airtight chamber formed by the first blind hole 5, and the adapter 101 of the pressure sensor and the cable plug 103 are both located in the detection closed chamber formed by the second blind hole 6. This state can be determined by Figure 15 To indicate this, it is only necessary to introduce a certain pressure of gas into the airtight chamber and then check whether the gas is present inside the airtight chamber to determine whether the pressure sensor is qualified. Specifically, if no gas is detected inside the airtight chamber, it means that the cavity seal of the adapter 101 is intact and the pressure sensor is qualified. Otherwise, it means that the cavity seal of the adapter 101 does not meet the standard and the pressure sensor is defective.

[0049] In summary, the utility model provides a first blind hole 5 for inserting the pressure interface 102 on the lower mold 2, and provides a second blind hole 6 for accommodating the adapter part 101 and the cable plug 103 on the upper mold 4. When the upper mold 4 and the lower mold 2 are in the mold closing state, the pressure interface 102 will be sealed in the first blind hole 5, and the adapter part 101 and the cable plug 103 will be sealed in the second blind hole 6, so that subsequent detection work can be conveniently implemented, the detection is simple, and the detection is accurate.

[0050] like Figures 8-11 As shown, in order to facilitate the detection of the gas in the airtight chamber and the detection of the gas in the airtight chamber, a first through hole is provided on the lower mold 2, and a connecting head 10 is sealed at the bottom end of the first through hole to form the above-mentioned first blind hole 5, and a first connecting hole 11 connected to the first blind hole 5 is provided on the connecting head 10, and the first connecting hole 11 can be opened and closed, that is, a valve can be provided on the first connecting hole 11; a second connecting hole 13 connected to the second blind hole 6 is provided on the upper mold 4, and the second connecting hole 13 can be opened and closed, that is, a valve can be provided on the second connecting hole 13. Through the setting of the first connecting hole 11 and the second connecting hole 13, two external hose connectors can be connected to the first connecting hole 11 and the second connecting hole 13 respectively, that is, the two hose connectors are connected to the airtight chamber and the detection closed chamber respectively. During subsequent testing, the two hose connectors can be connected to the corresponding components (air compressor, etc.) first, so that the valve on the second connecting hole 13 is in a closed state, and then the detection closed chamber is evacuated to make the valve on the first connecting hole 11 in an open state, and then a certain pressure of gas (helium or nitrogen, etc.) is introduced into the airtight chamber. By observing whether the gas is generated inside the detection closed chamber, the quality of the pressure sensor to be tested can be judged.

[0051] On the basis of setting the connecting head 10, a groove 12 for receiving the end of the pressure interface 102 is opened on the connecting head 10, so that the pressure interface 102 is coaxially arranged with the first connecting hole 11, so as to facilitate better gas supply to the pressure interface 102 through the first connecting hole 11.

[0052] like Figure 14As shown, further, after the pressure sensor is tested and qualified, it needs to be marked. The utility model is provided with a marking component 16 on the cabinet 14. The marking component 16 includes a power source 1601 fixedly provided on the cabinet 14 and a mark rod 1602 movably provided on the lower mold base 1, and the mark rod 1602 is located along its length direction on the execution end movement path of the power source 1601. The mark rod 1602 is arranged opposite to the adapter 101, and the lower mold base 1 is provided with a reset spring 1603 fixedly connected to the mark rod 1602. After the pressure sensor is tested and qualified, the power source 1601 can be used to drive the marker 1602 to move, so that the marker 1602 instantly contacts the surface of the pressure sensor to achieve marking; in this process, the reset spring 1603 will be compressed as the marker 1602 moves toward the pressure sensor. Subsequently, after the power source 1601 is reset, the reset spring 1603 will apply a certain elastic reset force to the marker 1602, so that the marker 1602 is reset, facilitating the next work.

[0053] It should be noted that the above-mentioned middle driving member 15 and power source 1601 can be set as a cylinder, an oil cylinder, a telescopic rod, etc., and this article does not impose any restrictions on this, as long as it can realize the reciprocating movement of the corresponding components.

[0054] like Figure 3-Figure 4 As shown, after the detection is completed, the upper mold 4 is reset, and the sealing of the airtight chamber and the detection airtight chamber is broken, and the gas inside the airtight chamber will accumulate inside the cabinet 14. In order to quickly dissipate the gas, the utility model also includes a blowing assembly, which includes fans 17 relatively arranged on both sides of the cabinet 14. The convection generated by the fans 17 on both sides can quickly discharge the gas from the cabinet 14.

[0055] like Figure 4 As shown, further, in order to ensure safety during the detection process, a protective component is also provided on the cabinet 14, which includes a cylinder 23 provided on the top of the cabinet 14 and a protective door 22 connected to the piston rod of the cylinder 23. During the pressure sensor detection process, the cylinder 23 will drive the protective door 22 downward to close the cabinet 14 to prevent staff from operating it incorrectly.

[0056] Example 2:

[0057] like Figures 8-12 and Figure 16-17As shown, this embodiment proposes a quick-release mechanism for a detection tool. The difference between this embodiment and the first embodiment is that the upper mold 4 and the lower mold 2 are detachably mounted on the upper mold base 3 and the lower mold base 1, respectively. The detachable installation of the two can achieve rapid replacement of the upper mold 4 and the lower mold 2, facilitating the detection of different types of pressure sensors. Specifically, the detachable installation of the upper mold 4 and the lower mold 2 is designed as follows:

[0058] (1) Upper mold 4, a slot 27 for inserting upper mold 4 is provided on one end of upper mold base 3 facing lower mold 2, and a positioning pin 21 is movably inserted on upper mold base 3, and one end of positioning pin 21 passes through slot 27, and a connecting spring (not shown in the figure) or other elastic component fixedly connected to positioning pin 21 is provided on upper mold base 3, so that positioning pin 21 can automatically reset after being pulled outward for a distance on upper mold base 3; an assembly hole 9 is provided on the side of upper mold 4, after upper mold 4 is inserted into assembly hole 9 from bottom to top, under the action of connecting spring, positioning pin 21 always contacts with the side of upper mold 4, and positioning pin 21 has a movement tendency to move toward upper mold 4, and at this time, upper mold 4 can be rotated until one end of positioning pin 21 is inserted into assembly hole 9, thereby completing the assembly of upper mold 4 and upper mold base 3. Subsequently, it is only necessary to pull the positioning pin 21 outwards so that the positioning pin 21 is away from the assembly hole 9 to release the lock on the positioning pin 21 and realize the disassembly of the upper mold 4 and the upper mold base 3.

[0059] (2) Lower die 2: A slot 28 for inserting the lower die 2 is provided on the side of the lower die base 1 facing the upper die 4. At the same time, a pressure seat 19 is detachably mounted on the lower die base 1 via a knob 20. A plurality of protrusions are provided on one side of the pressure seat 19 along its length, and an escape zone 24 is formed between any two adjacent protrusions. When the pressure seat 19 is mounted on the lower die base 1 using the knob 20, the pressure seat 19 presses a portion of the lower die 2 onto the slot 28, and the other portion of the lower die 2 is located within the escape zone 24. By providing a plurality of escape zones 24 on the pressure seat 19, a single pressure seat 19 can simultaneously press a plurality of lower dies 2 while also allowing them to escape. Furthermore, the pressure seat 19 and the lower die base 1 can be disassembled and assembled by turning the knob 20, making it easy to use.

[0060] like Figure 7 As shown, in order to sense whether a pressure sensor to be detected is placed on the lower mold 2, a photoelectric switch sensor 18 can be provided on the pressure seat 19 on the basis of the above-mentioned pressure seat 19, and a working hole 26 for the emission end of the photoelectric switch sensor 18 to emit light is opened on the pressure seat 19. At the same time, based on the above-mentioned setting of the marking component 16, in order to adapt to the simultaneous use of the marking component 16 and the pressure seat 19, a through hole 25 for the mark rod 1602 to pass through can be opened on the pressure seat 19, and the mark rod 1602 can pass through the avoidance area 24.

[0061] The above describes an embodiment of the present invention in detail. However, the above content is only a preferred embodiment of the present invention and should not be considered to limit the scope of implementation of the present invention. All equivalent changes and improvements made within the scope of the present invention should still fall within the scope of the patent application of the present invention.
