Description

Technical Field

[0001] The present invention relates to the technical field of pressure switch sensor detection, and particularly relates to a pressure switch sensor detection device. Background Art

[0002] A pressure switch sensor is a device that converts pressure into current / voltage, and is mainly used to measure physical quantities such as pressure and displacement. It is widely used in industrial automation, medical equipment, aerospace and other fields. By detecting the voltage, the corresponding pressure value can be obtained. In addition, it also controls the load execution through pressure. It adopts a metal diaphragm method, with fixed contacts suspended and fixed by a metal elastic diaphragm; the movable contact is welded in the center of the metal elastic diaphragm through a special process, and the metal elastic diaphragm is then fixed in the pressure interface through sealing. Under the action of pressure, the metal diaphragm deforms within the range of elastic deformation. Through the center support rod, the deformed diaphragm drives the movable contact of the switch to move up and down axially to contact the fixed contact, thereby controlling the load to execute the command.

[0003] The working reliability of the pressure switch sensor is an important guarantee to ensure the reliable operation of the pressure detection system and other pressure control systems. Manually connect the signal wire and the positive and negative wires of the pressure switch sensor to the load, and after manually starting, observe whether the load is executed. Judge whether the pressure switch sensor is qualified through the execution state of the load. If this pure manual wiring method is used for batch detection, the detection efficiency will be low. Summary of the Invention

A working cavity is provided in the vertical direction of the vertical seat, and the pressure switch sensor is located in the working cavity to complete the test. A vertical connection part is formed on the left side of the working cavity. A positioning structure is provided in the working cavity, and the positioning structure includes a first positioning part arranged on the top end of the working cavity and a second positioning part arranged on the bottom end of the working cavity. The upper end of the working cavity reaches the first positioning part and is horizontal, and the lower two ends of the working cavity reach the second positioning part and are horizontal. A first positioning hole communicating up and down is provided on the first positioning part, and a second positioning hole communicating up and down is also provided on the first positioning part. A second positioning hole communicating up and down is provided on the second positioning part, and the second positioning hole coincides with the first positioning hole up and down on the same straight line. A detection component is also provided on the working cavity, and the detection component includes a test load installed on the connection part, an electric cylinder installed on the first positioning part, and a button installed on the bottom surface of the first positioning part. The action rod of the electric cylinder is vertically downward and is installed with a pressing plate, and the pressing plate is located above the first positioning hole; the positioning structure further includes a first spring fixed on the second positioning part and vertically upward, and a positioning plate is installed at the top end of the first spring. A third positioning hole is provided on the positioning plate. The detection component further includes a fixed sleeve installed in the second positioning hole and a second spring fixed in the fixed sleeve. The second spring is sleeved on the inner periphery of the first spring, and the second spring is vertically upward and is installed with a contact pressing plate at the top end. The center of the third positioning hole and the center of the contact pressing plate are on the same axis, and the contact pressing plate is located on the bottom side of the positioning plate. A positive terminal and a negative terminal are installed on the first positioning part, and the bottom ends of the positive terminal and the negative terminal are vertically beside the second positioning hole.

[0005] As a further preference, the support strength of the second spring is higher than that of the first spring.

[0006] As a further preference, a vertically downward connecting column is fixed on the bottom surface of the second positioning part, and a threaded hole is provided on the connecting column.

[0007] As a further preference, a quick installation groove is opened inward from the outer side of the bottom surface of the first positioning part, and the inner end of the quick installation groove communicates with the first positioning hole.

[0008] As a further preference, planes are provided on both sides of the top end of the vertical seat, damping shafts are installed on the two planes, a swing frame is installed between the two damping shafts, and the positive terminal and the negative terminal are installed on the swing frame.

[0009] As a further preference, two contact plates are installed on the bottom surface of the top end of the swing frame. The positive terminal and the negative terminal are bolts. The bottom ends of the positive terminal and the negative terminal pass through the bottom of the top end of the swing frame. The top ends of the two contact plates are respectively connected to the positive terminal and the negative terminal. The two contact plates are perpendicular downward, and elastic contacts are provided on the opposite surfaces of the bottom ends of the two contact plates. The second positioning holes are in two positions on the left and right. The two elastic contacts are respectively beside the upper sides of the two second positioning holes on the left and right. The two contact plates are elastic metal plates.

[0010] As a further preference, the button is a momentary button, the button faces downward and faces the positioning plate. The normally open contact of the button is electrically connected to the electric cylinder.

[0012] The beneficial effects of the present invention compared with the prior art are:

[0013] During use, place the bottom end of the pressure switch sensor on the feed platform. The positioning plate pushes the top end of the pressure switch sensor to drive the positive and negative plates into the quick-installation groove. The pressure sensing end falls into the third positioning hole and corresponds to the upper side of the pressure contact plate. After releasing the hand, the first spring releases elastic force upward and pushes the positioning plate to rise quickly. The positioning plate pushes the pressure switch sensor to rise, and the positive and negative plates are quickly butted against the two elastic contacts to connect the power supply and the signal. The signal is transmitted to the test load through the signal line. At the same time, the top end of the pressure switch sensor penetrates into the first positioning hole, and the top surface of the pressure switch sensor leans against the button. The button commands the electric cylinder to act. The electric cylinder pushes the pressing plate against the top end. The pressure contact plate provides a reaction force to the pressure sensing end to provide a signal to the pressure switch sensor and transmit the signal to the test load. If the test load operates, it is measured that the pressure switch sensor is qualified. If the test load is still stationary, it is measured that the pressure switch sensor is damaged. In a mass production environment, replace the next pressure switch sensor in the same way and complete the test in the same method. During the operation process, only need to install the pressure switch sensor into the working cavity from the side. Through the above series of coherent actions, the pressure switch sensor is quickly positioned and quickly tested. Its positive and negative plates do not need to be manually butted by humans, the positioning is accurate, and the detection efficiency and quality are relatively high. Description of the Drawings

Specific embodiments

[0022] The following will clearly and completely describe the above and other embodiments and advantages of the present invention with reference to the accompanying drawings. Obviously, the described embodiments are only partial embodiments of the present invention, rather than all embodiments.

[0023] In one embodiment, as Figures 1-7 shown:

[0024] This embodiment provides a pressure switch sensor detection device, including a vertical base 1. A working cavity 2 is formed in the vertical direction of the vertical base 1. The pressure switch sensor is located in the working cavity 2 to complete the test. A vertical connection part 3 is formed on the left side of the working cavity 2. A positioning structure is arranged in the working cavity 2. The positioning structure includes a first positioning part 4 arranged on the top end of the working cavity 2 and a second positioning part 5 arranged on the bottom end of the working cavity 2. The upper end of the working cavity 2 reaches the first positioning part 4 and is horizontal. The lower two ends of the working cavity 2 reach the second positioning part 5 and are horizontal. A first positioning hole 6 communicating up and down is formed in the first positioning part 4. A second positioning hole 7 communicating up and down is also formed in the first positioning part 4. A fixing hole 8 communicating up and down is formed in the second positioning part 5. The fixing hole 8 and the first positioning hole 6 overlap vertically on the same straight line. A detection component is also arranged on the working cavity 2. The detection component includes a test load 9 installed on the connection part 3, an electric cylinder 10 installed on the first positioning part 4, and a button 12 installed on the bottom surface of the first positioning part 4. The action rod of the electric cylinder 10 is vertically downward and is installed with a pressing plate 11. The pressing plate 11 is located above the first positioning hole 6. The positioning structure further includes a first spring 13 fixed on the second positioning part 5 and vertically upward. The top end of the first spring 13 is installed with a positioning plate 14. A third positioning hole 15 is formed in the positioning plate 14. The detection component further includes a fixing sleeve 16 installed in the fixing hole 8 and a second spring 17 fixed in the fixing sleeve 16. The second spring 17 is sleeved on the inner periphery of the first spring 13. The second spring 17 is vertically upward and is installed with a contact pressing plate 18 at the top end. The center of the third positioning hole 15 and the center of the contact pressing plate 18 are on the same axis. The contact pressing plate 18 is located on the bottom side of the positioning plate 14. A positive terminal 19 and a negative terminal 20 are installed on the first positioning part 4. The bottoms of the positive terminal 19 and the negative terminal 20 are perpendicular to the side of the second positioning hole 7.

[0025] A connecting column 21 vertically downward is fixed on the bottom surface of the second positioning part 5. A threaded hole 22 is formed in the connecting column 21. When the whole detection device is actually used, it is connected to the detection table through the threaded hole 22. When the pressure switch sensor A is placed in the working cavity 2 for positioning and testing, it can prevent the whole testing device from moving.

[0026] A quick installation groove 23 is formed from the outer side of the bottom surface of the first positioning part 4 inward. The inner end of the quick installation groove 23 communicates with the first positioning hole 6.

[0027] On both sides of the top end of the upright base 1, flat surfaces 24 are provided. Damping shafts are installed on the two flat surfaces 24. A swing frame 25 is installed between the two damping shafts. A positive terminal 19 and a negative terminal 20 are installed on the swing frame 25. On the bottom surface of the top end of the swing frame 25, two left and right contact plates 26 are installed. The positive terminal 19 and the negative terminal 20 are bolts. The bottom ends of the positive terminal 19 and the negative terminal 20 pass through the bottom of the top end of the swing frame 25. The top ends of the two contact plates 26 are respectively connected to the positive terminal 19 and the negative terminal 20. The two contact plates 26 are perpendicular downward, and elastic contacts 27 are provided on the opposite surfaces of the bottom ends of the two contact plates 26. The second positioning holes 7 are in two places on the left and right. The two elastic contacts 27 are respectively beside the upper sides of the two left and right second positioning holes 7. The two contact plates 26 are elastic metal plates.

[0028] The button 12 is a momentary action button. The button 12 faces downward and faces the positioning plate 14. The normally open contact of the button 12 is electrically connected to the electric cylinder 10. When the normally open contact of the button 12 is closed, the electric cylinder 10 is automatically started, and the pressing plate 11 is driven by the electric cylinder 10 to automatically descend. On the bottom surface of the top end of the upright base 1, the inner end of the quick-installation groove 23 communicates with the second positioning hole 7. A feed platform 29 corresponding to the lower part of the quick-installation groove 23 is installed on the positioning plate 14. The outer end of the feed platform 29 extends beyond the outer end of the quick-installation groove 23.

[0029] The upright base 1 is made of hard rubber. The opening of the working cavity 2 enables the working cavity 2 to be insulated and isolated from the test load 9 through the connecting part 3. At the same time, the working cavity 2 serves as the placement area for the pressure switch sensor A during the test, preventing the pressure switch sensor A from generating static electricity during the test.

[0030] During use, place the bottom end of the pressure switch sensor A on the feed platform 29, apply force downward to press, so that the feed platform 29 drives the positioning plate 14 to descend, and the first spring 13 is pushed by the positioning plate 14 to compress downward and store elastic force. The top end B of the pressure switch sensor A drives the positive and negative plates D into the quick-installation groove 23, continue to push the pressure switch sensor A, so that its pressure sensing end C falls into the third positioning hole 15 and corresponds to the upper side of the pressure contact plate 18, and the body of the switch sensor A is stuck into the working cavity 2, and the positive and negative plates D reach below the second positioning hole 7 along the quick-installation groove 23. After releasing the hand, the first spring 13 releases the elastic force upward and pushes the positioning plate 14 to rise quickly. The positioning plate 14 pushes the pressure switch sensor A to rise, and the pressure switch sensor A drives the positive and negative plates D to rise. The positive and negative plates D are quickly docked on the two elastic contacts 27 as shown in the figure, connecting the power supply and the signal, and the signal is transmitted to the test load 9 through the signal wire. At the same time, the top end B of the pressure switch sensor A penetrates into the first positioning hole 6. At this time, both the upper and lower ends of the pressure switch sensor A are quickly positioned on the detection device, and as the positioning plate 14 pushes the pressure switch sensor A upward, the top surface of the pressure switch sensor A leans against Figure 5 shown in the figure, quickly docked on the two elastic contacts 27, connecting the power supply and the signal, and the signal is transmitted to the test load 9 through the signal wire. At the same time, the top end B of the pressure switch sensor A penetrates into the first positioning hole 6. At this time, both the upper and lower ends of the pressure switch sensor A are quickly positioned on the detection device, and as the positioning plate 14 pushes the pressure switch sensor A upward, the top surface of the pressure switch sensor A leans against Figure 2, Figure 4 On the button 12 shown, the normally closed contact of the button 12 closes, and commands the electric cylinder 10 to act. The action rod of the electric cylinder 10 pushes the pressing plate 11 downward, causing the pressing plate 11 to press against the top end B. The top end B pushes the pressure switch sensor A to descend again. The pressure switch sensor A drives the pressure sensing end C to descend, and the pressure sensing end C lands on the pressure contact plate 18. The pressure contact plate 18 provides a reaction force to the pressure sensing end C to provide a signal to the pressure switch sensor A and transmit the signal to the test load 9. If the test load 9 operates, it is measured that the pressure switch sensor A is qualified. If the test load 9 remains stationary, it is measured that the pressure switch sensor A is damaged. After the test is completed, the feeding platform 29 is pushed. The feeding platform 29 drives the positioning plate 14 to descend. The positioning plate 14 drives the pressure switch sensor A to descend. The pressure switch sensor A drives the positive and negative plates D to descend into the working cavity 2. Then, the pressure switch sensor A is removed from the opening side of the working cavity 2. In a mass production environment, the next pressure switch sensor A is replaced by analogy, and the test is completed in the same way. During the operation process, only the pressure switch sensor A needs to be loaded into the working cavity 2 from the side. Through the above series of coherent actions, the pressure switch sensor A is quickly positioned and quickly tested. Its positive and negative plates D do not need to be manually docked by humans, with accurate positioning and high efficiency. Before the test, the pressure switch sensor A is quickly positioned in the working cavity 2. During the test, the pressure switch sensor A does not shake. When providing a pressure signal to the pressure sensing end C, since the pressure switch sensor A is positioned, the signal quality of the pressure switch sensor A is guaranteed, and the detection quality is high.

[0031] It should be further noted that the support strength of the second spring 17 is higher than that of the first spring 13. When the pressing plate 11 pushes the pressure switch sensor A downward, the bottom end of the pressure switch sensor A lands on the positioning plate 14 and pushes the positioning plate 14 to descend. When the pressure sensing end C at the bottom of the pressure switch sensor A lands on the pressure contact plate 18, although the pressure contact plate 18 descends, the elastic strength of the second spring 17 is sufficient to hold the pressure contact plate 18 against the pressure sensing end C and provide an upward reaction force signal to the pressure sensing end C.
