Description

Technical Field

[0001] This application relates to the field of pressure head detection equipment technology, and in particular to a floating mechanism and pressure head detection device. Background Technology

[0002] After some components of Bluetooth headsets are connected using PSA (Pressure Swing Adsorption) technology, pressure holding equipment is required. To ensure the accuracy of the pressure holding machine, it needs to be inspected regularly. Each station has a specific pressure calibration block with different heights. When the inspector makes a mistake, such as using a 60mm high pressure calibration block in the position of a 40mm high calibration block, if the inspector does not detect it in time, the pressure head will be damaged due to excessive pressure. Utility Model Content

[0003] The purpose of this application is to provide a floating mechanism and a pressure head detection device to solve the problem of excessive pressure causing pressure head damage after misoperation.

[0004] Therefore, in a first aspect, embodiments of this application provide a floating mechanism, including:

[0005] Base;

[0006] A first mounting component and a second mounting component are disposed at a distance from the base, and at least the second mounting component is movable along the base;

[0007] An elastic element connects the first mounting component and the second mounting component;

[0008] The connecting bracket is fixedly connected to the first mounting component and movably connected to the second mounting component.

[0009] In one possible implementation, a counterweight component is also included, which is mounted on the first mounting component.

[0010] In one possible implementation, the counterweight assembly includes a counterweight block and a locking element, wherein the counterweight block is detachably mounted to the first mounting assembly via the locking element.

[0011] In one possible implementation, the connecting frame is provided with a limiting structure that restricts the range of motion of the second mounting component.

[0012] In one possible implementation, the first mounting component is also movable along the base in the same direction as the second mounting component. In the direction of movement, the base is provided with limiting members that respectively restrict the travel of the first mounting component and the second mounting component.

[0013] Secondly, embodiments of this application provide a pressure head detection device, comprising:

[0014] Erecting the frame;

[0015] As described in the first aspect, the floating mechanism is movably disposed on the upright;

[0016] A driving element is disposed on the upright, and the driving element is configured to drive the floating mechanism to move along the upright;

[0017] A detection component is disposed on the stand and is configured to detect the pressure of the pressure head mounted on the second mounting component.

[0018] In one possible implementation, the movable end of the drive member is connected to a first connecting plate, the first connecting plate is connected to a second connecting plate via a connector, and the second connecting plate is connected to the floating mechanism; in the direction of movement of the movable end of the drive member, the connector enables a preset connection force between the first connecting plate and the second connecting plate.

[0019] In one possible implementation, the connector includes a magnetic block.

[0020] In one possible implementation, a buffer component is also included, which is disposed on the support and located on the movement path of the floating mechanism, and is configured to buffer the floating mechanism when it moves to a defined position.

[0021] In one possible implementation, the position of at least one of the floating mechanism and the detection component can be adjusted on the stand.

[0022] According to the floating mechanism and pressure head detection device provided in the embodiments of this application, the pressure head is installed on the floating mechanism. When the pressure head is tested, if the height of the placed calibration block is greater than the height of the calibration block required for this station, the second mounting component will move towards the direction closer to the first mounting component, avoiding the situation where the pressure head and the calibration block interfere with each other and cause damage to the pressure head. This solves the problem of excessive pressure causing pressure head damage after misoperation. Furthermore, if the placed calibration block is not the calibration block required for this station, the pressure head and the calibration block will interfere with each other when the pressure head is pressed down for testing. At this time, the floating mechanism will separate from the driving component, so that the pressure head and the calibration block will not be over-compressed, thus avoiding damage to the pressure head.

[0049] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0050] like Figures 1-2 As shown in the figure, this application embodiment provides a floating mechanism, including a base 1, a first mounting component 2, a second mounting component 3, an elastic element 5, and a connecting frame 7. The first mounting component 2 and the second mounting component 3 are spaced apart from each other on the base 1, and at least the second mounting component 3 is movable along the base 1. The elastic element 5 connects the first mounting component 2 and the second mounting component 3; the connecting frame 7 is fixedly connected to the first mounting component 2 and movably connected to the second mounting component 3.

[0051] The pressure head 6 is mounted on the floating mechanism. When the pressure head 6 is tested, if the height of the calibration block placed is greater than the height of the calibration block required for this station, the second mounting component 3 will move towards the first mounting component 2. This avoids the pressure head 6 from interfering with the calibration block and causing damage to the pressure head 6. This solves the problem of excessive pressure causing damage to the pressure head 6 after misoperation.

[0052] Specifically, the elastic element 5 connects the first mounting component 2 and the second mounting component 3. With the first mounting component 2 in an unchanged position, the second mounting component 3 can move towards the first mounting component 2 by compressing the elastic element 5. Under the elastic restoring force of the elastic element 5, the second mounting component 3 can also move away from the first mounting component 2. Within the movement range of the second mounting component 3, it can contain the misaligned calibration block, preventing interference between the calibration block and the pressure head 6.

[0053] To ensure the reliability of the connection of the elastic element 5, two or more elastic elements 5 can be arranged at intervals. The elastic element 5 can be a component that can achieve elastic expansion and contraction, such as a spring.

[0054] In addition, the first mounting component 2 and the second mounting component 3 are connected by the connecting bracket 7 to ensure the stability of the movement of the second mounting component 3, prevent the second mounting component 3 from shaking during movement, and ensure the stability and reliability of the pressure head 6.

[0055] Reference Figure 1 and Figure 2 The first mounting component 2 includes a first mounting part 201 and a first connecting part 202, which are vertically connected. The first mounting part 201 is disposed on the base 1. The second mounting component 3 includes a second mounting part 301 and a second connecting part 302, which are vertically connected. The second mounting part 301 is movably disposed on the base 1. The connecting frame 7 is connected to the first mounting part 201 and the second mounting part 301 respectively. The first connecting part 202 and the second connecting part 302 are arranged parallel to each other in the vertical direction, and the first connecting part 202 is disposed above the second connecting part 302. The two ends of the elastic member 5 are connected to the first connecting part 202 and the second connecting part 302 respectively. The upper and lower sides of the fixed base 4 are connected to the second connecting part 302 and the pressure head 6 respectively.

[0056] In some embodiments, the floating mechanism further includes a counterweight component 9 mounted on the first mounting component 2. When the second mounting component 3 is stationary, the pressure of the first mounting component 2 on the elastic element 5 is adjusted by adjusting the weight of the counterweight component 9 on the first mounting component 2, thereby adjusting the pressure of the pressure head 6 on the second mounting component 3 on the calibration block, thus achieving fine-tuning.

[0057] The counterweight assembly 9 includes a counterweight block 91 and a locking member 92. The counterweight block 91 is detachably mounted on the first mounting assembly 2 via the locking member 92. The locking member 92 includes a screw or a bolt. Taking the locking member 92 as a screw, the screw is screwed into the first mounting assembly 2 and passes through the counterweight block 91, thereby connecting the counterweight block 91 to the first mounting assembly 2. To ensure the reliability of the connection, there may be two or more locking members 92.

[0058] Reference Figure 1 and Figure 2 In some embodiments, the connecting frame 7 is provided with a limiting structure 8 to restrict the range of motion of the second mounting component 3. Specifically, the limiting structure 8 includes a first mating member 81 and a second mating member 82 movably disposed on the first mating member 81 along the direction of movement of the second mounting component 3. The limiting structure 8 also includes a first limit portion and a second limit portion to restrict the movement of the second mating member 82. One of the first mating member 81 and the second mating member 82 is disposed on the connecting frame 7, and the other is disposed on the second mounting component 3. When the second mounting component 3 moves toward the first mounting component 2, the movement of the second mating member 82 is restricted when it reaches the point where it abuts against the first or second limit portion, thus restricting the movement of the second mounting component 3. Similarly, when the second mounting component 3 moves away from the first mounting component 2, the movement of the first mating member 81 is restricted when it reaches the point where it abuts against the first or second limit portion, thus restricting the movement of the second mounting component 3.

[0059] The fit between the first mating component 81 and the second mating component 82 includes a connection between a slide rail and a slide path, or a connection between a moving block and a moving groove. Specifically, one of the first mating component 81 and the second mating component 82 is a moving groove extending along the direction of movement of the second mounting assembly 3, and the other is a moving block embedded within the moving groove; the first limit portion and the second limit portion are respectively the two ends of the moving groove.

[0060] For ease of description, this embodiment uses the vertical direction of movement of the second mounting component 3 as the description. It can be understood that the direction of movement of the second mounting component 3 can also be any horizontal direction. Therefore, the elastic member 5 also elastically expands and contracts in the vertical direction. The first mating member 81 and the second mating member 82 also move and engage in the vertical direction. The first limit part and the second limit part are respectively located on both sides of the second mating member 82 in the vertical direction.

[0061] Reference Figure 1 and Figure 2 For example, the first mating part 81 can be a movable groove, and the second mating part 82 can be a movable block. The movable groove extends vertically, and the movable block is embedded in the movable groove. In this case, the first limit part and the second limit part can be the two ends of the movable groove in the vertical direction. Of course, the first limit part and the second limit part can also be a stop block provided on the connecting frame 7, and are spaced apart on the moving path of the second mating part 82, thereby limiting the second mating part 82 to move between the first limit part and the second limit part. Thus, it can be ensured that the second mounting component 3 can move relative to the first mounting component 2, and it can also avoid the movement distance being too large, which could lead to misoperation, such as placing calibration blocks of different sizes at other points on it for inspection.

[0062] Of course, one of the movable block and the movable slot is disposed on the connecting frame 7, and the other is disposed on the second mounting component 3. In this embodiment, the movable slot is opened on the connecting frame 7, the movable block is fixedly disposed on the second mounting component 3, and the first limit part is located above the second limit part. When the pressure head 6 presses against the calibration block 20, the movable block is located in the movable slot and can abut against the second limit part, or there is a gap between it and the second limit part. When the calibration block 20 needs to be replaced, the second mounting component 3 is moved upward, and the pressure head 6 is moved away from the calibration block 20. At this time, the movable block moves towards the direction close to the first limit part. Then, the replaced calibration block 20 is placed on it, and the pressure head 6 is moved downward for inspection.

[0063] Of course, fixing the connecting bracket 7 to the first mounting component 2 includes welding the connecting bracket 7 to the first mounting component 2, or fixing the connecting bracket 7 to the first mounting component 2 by means such as screwing or snap-fitting. In this embodiment, the connecting bracket 7 is fixed by screwing it into the first mounting component 2. To ensure the connection effect, two screws are provided. Of course, multiple screws can also be provided.

[0064] Reference Figures 1-3 In some embodiments, the first mounting component 2 can also move along the base 1 in the same direction as the second mounting component 3. In the direction of movement, the base 1 is provided with limiting members 13 that respectively limit the movement stroke of the first mounting component 2 and the second mounting component 3.

[0065] When an operator makes a mistake and places an incorrect calibration block on it, and the moving block moves upward until it touches the first limit, but still cannot mate the calibration block with the pressure head 6, the operator can make a preliminary judgment on the mistake. Then, the second mounting component 3 can continue to move upward, and under the connection of the mounting bracket 7, the first mounting component 2 moves upward synchronously, thereby ensuring that the calibration block mates with the pressure head 6 and avoiding interference between the calibration block and the pressure head 6, which could lead to damage to the pressure head 6.

[0066] For ease of description, this application refers to the limiting member 13 used to limit the first mounting component 2 as the first limiting part 131, and the limiting member 13 used to limit the second mounting component 3 as the second limiting part 132. The first limiting part 131 is fixedly disposed on the base 1 and located above the first mounting component 2, thereby limiting the continued upward movement of the first mounting component 2; the second limiting part 132 is fixedly disposed on the base 1 and located below the second mounting component 3, thereby limiting the continued downward movement of the first mounting component 2, thus ensuring the reliability of the device.

[0067] Of course, in order to ensure the reliability of limiting the first mounting component 2, the first limiting part 131 can be provided in two or more at intervals. Similarly, in order to ensure the reliability of limiting the second mounting component 3, the second limiting part 132 can be provided in two or more at intervals.

[0068] In summary, the floating mechanism provided in this application embodiment has the pressure head 6 mounted on it. When pressure testing is performed on the pressure head 6, if the inspector makes a mistake, such as mistakenly using a 60mm high calibration block in the position of a 40mm high calibration block, and if the inspector cannot detect this in time, the second mounting component 3 will move upward during the inspection to avoid interference between the pressure head 6 and the calibration block, thus preventing damage to the pressure head 6.

[0069] Furthermore, when the second mounting component 3 moves to its limit position in the moving slot and still does not meet the height requirement of the verification block, based on the connecting effect of the connecting frame 7, the second mounting component 3 will drive the connecting frame 7 to move the first mounting component 2 upward synchronously until the first mounting component 2 moves to abut against the first limiting part 131, which can provide the maximum placement area for the verification block.

[0070] Existing pressure head testing devices drive the reciprocating motion of the pressure head 6 via the extension and retraction of a cylinder telescopic rod, enabling the pressure head 6 to move back and forth between two points for inspection of the calibration block. However, during this process, if the inspector makes a mistake, such as inserting a finger between the pressure head 6 and the calibration block, there is a risk of finger injury. In this application, by adjusting the position of the base 1, no adjustment of the base 1 is required during inspection. Only the position of the second mounting component 3 needs to be moved, and the elastic element 5 and the limiting structure 8 ensure stable reciprocating motion of the second mounting component 3, thus achieving the inspection of the calibration block. This simplifies operation, and even if the inspector makes a mistake, such as inserting a finger between the pressure head 6 and the calibration block, finger injury will not occur, improving the safety of the device.

[0071] Meanwhile, if the inspection personnel make a mistake, such as placing a calibration block that is taller than the required height of the calibration block for this station, the second mounting component 3 will move upward. When the second mounting component 3 moves to its limit position in the moving slot and still cannot put the calibration block in, the second mounting component 3 can drive the connecting frame 7 and the first mounting component 2 to move upward synchronously, effectively avoiding interference between the pressure head 6 and the calibration block and preventing damage to the pressure head 6.

[0072] like Figures 1-6 As shown in the illustration, this application also provides a pressure head detection device, which includes a floating mechanism as described in the foregoing embodiments. The device further includes a support frame 10, a driving member 11, and a detection assembly. The floating mechanism is mounted on the support frame 10, and the driving member 11 is mounted on the support frame 10. The driving member 11 is configured to drive the floating mechanism to move along the support frame 10, and the direction of movement of the floating mechanism is the same as the direction of movement of the second mounting assembly 3. The detection assembly is mounted on the support frame 10 and is configured to detect the pressure of the pressure head 6 mounted on the second mounting assembly 3.

[0073] The pressure head 6 is mounted on the floating mechanism, and the detection component is used to cooperate with the pressure head 6. The driving component 11 drives the movement of the floating mechanism, so that the pressure head 6 on the floating mechanism can cooperate with the detection component to detect the pressure of the pressure head 6.

[0074] The detection component includes a calibration block 20, on which a pressure gauge 14 is placed. The pressure head 6 presses against the pressure gauge 14, and the pressure gauge 14 performs pressure detection on the pressure head 6.

[0075] The driving component 11 is configured to drive the floating mechanism to move along the upright 10. The movable end of the driving component 11 is connected to the base 1. The driving component 11 is used to drive the base 1 to move, and the movement of the base 1 will simultaneously drive the second mounting assembly 3 to move synchronously. Specifically, the driving component 11 includes a driving cylinder with a vertically extending piston rod. The extension and retraction of the piston rod will drive the base 1 to rise and fall, thereby driving the second mounting assembly 3 to rise and fall. Of course, the driving component 11 can also be an electric push rod or other components that can achieve driving movement.

[0076] In some embodiments, the movable end of the drive member 11 is connected to a first connecting plate 15, and the first connecting plate 15 is connected to a second connecting plate 16 via a connector 17. The second connecting plate 16 is connected to the floating mechanism, that is, the second connecting plate 16 is connected to the base 1. In the moving direction of the movable end of the drive member 11, the connector 17 provides a preset connecting force between the first connecting plate 15 and the second connecting plate 16. When the piston rod of the drive cylinder extends, it drives the base 1 to move upward, and when the piston rod of the drive cylinder retracts, it drives the base 1 to move downward.

[0077] Reference Figures 3-6 The preset connection force allows the first connecting plate 15 to move synchronously with the second connecting plate 16 during the movement of the first connecting plate 15. The second connecting plate 16 is connected to the base 1, and the movement of the second connecting plate 16 will drive the base 1 to move synchronously. The pressure head 6 on the base 1 will also move synchronously. When the driving member 11 drives the first connecting plate 15 to move down until the pressure head 6 presses against the verification block 20, the driving member 11 will continue to drive the first connecting plate 15 to move down, which will be greater than the preset connection force. The first connecting plate 15 will then separate from the second connecting plate 16, thereby ensuring that the base 1 will not continue to move with the downward movement of the driving member 11 and protecting the pressure head 6 from damage.

[0078] The connector 17 includes a magnetic block, and the first connecting plate 15 and the second connecting plate 16 are magnetically attracted to each other; the connector 17 may also include an adhesive component, and the first connecting plate 15 and the second connecting plate 16 are adhesively attracted to each other. In this embodiment, the connector 17 is a magnetic block, and two magnetic blocks are provided, and the first connecting plate 15 and the second connecting plate 16 are magnetically attracted together by the two magnetic blocks.

[0079] In some embodiments, the pressure head detection device further includes a buffer assembly 12, which is disposed on the support frame 10 and located on the movement path of the floating mechanism. The buffer assembly 12 is configured to buffer the floating mechanism when it moves to a predetermined position. The buffer assembly 12 can be a flexible component, such as a rubber pad or a silicone pad.

[0080] In addition, the buffer assembly 12 may also include a buffer frame 121 disposed on the upright frame 10, and a buffer 122 disposed on the buffer frame 121, the buffer 122 being located on the movement path of the base 1; the placement of the buffer 122 restricts the movement of the base 1, thereby avoiding the risk of the base 1 continuing to move.

[0081] Specifically, the buffer frame 121 is positioned below the base 1, and the buffer 122 is aligned with the base 1. The extension and retraction of the piston rod of the drive cylinder causes the base 1 to rise and fall. When the base 1 descends to abut against the buffer 122, the base 1 cannot move further down due to the limiting effect of the buffer 122. It can be seen that when the base 1 moves down, the pressure head 6 moves towards the calibration block 20. By limiting the maximum descent position of the base 1, interference between the pressure head 6 and the calibration block 20, which could cause damage, can be avoided.

[0082] Furthermore, when the base 1 moves to contact the buffer 122, and the drive member 11 drives the first connecting plate 15 to continue moving downward, the downward driving force of the drive member 11 and the upward force of the buffer 122 on the base 1 will be greater than the preset connection force. The first connecting plate 15 will separate from the second connecting plate 16, and the base 1 will not continue to move with the downward movement of the drive member 11, thus protecting the pressure head 6 from damage.

[0083] Of course, in order to ensure the safety of the buffer 122, a buffer rod 123 can also be provided on the buffer frame 121. The end face height of the buffer rod 123 is the same as the end face height of the buffer 122, and together with the buffer 122, it plays the role of buffering and limiting.

[0084] In some embodiments, the position of at least one of the floating mechanism and the detection component can be adjusted on the stand 10, thereby adjusting the relative position between the pressure head 6 and the calibration block 20, ensuring accurate contact between the pressure head 6 and the pressure gauge 14, and ensuring the detection effect.

[0085] Specifically, the pressure head detection device also includes a first adjustment module 18 disposed on the stand 10. The first adjustment module 18 includes a stand 181 and an adjustment member 182. The stand 181 is disposed on the movable end of the drive member 11. The adjustment member 182 is movably disposed on the stand 181 along a first direction, which is perpendicular to the movement direction of the second mounting component 3. The base 1 is disposed on the adjustment member 182. During the adjustment process of the adjustment member 182, the position of the pressure head 6 on the base 1 is adjusted.

[0086] Of course, the base 1 can also be movably mounted on the adjusting member 182 along the movement direction of the second mounting component 3.

[0087] The stand 181 is mounted on the second connecting plate 16 and is movably mounted on the frame 10 in the vertical direction. The adjusting member 182 is movably mounted on the stand 181 in a first direction, which is perpendicular to the movement direction of the second mounting component 3. The second mounting component 3 moves in the vertical direction, and the first direction is a horizontal direction perpendicular to the vertical direction. The base 1 moves in the vertical direction.

[0088] The movement of the adjusting member 182 and the base 1 can be achieved by a driver, such as a cylinder or an electric push rod. In this embodiment, the adjusting member 182 and the base 1 are connected by a positioning pin and a positioning hole, or by a screw and a threaded hole. For example, multiple threaded holes are provided at intervals along the first direction on the stand 181. The position of the adjusting member 182 relative to the stand 181 is achieved by the cooperation of the screw with different threaded holes, thus realizing the movement of the adjusting member 182 along the first direction. Similarly, the position of the base 1 relative to the adjusting member 182 is also realized, thus realizing the vertical movement adjustment of the base 1.

[0089] Reference Figure 3 , Figure 8 The support frame 10 is also connected to a platform 19. A positioning component 21 is provided on the platform 19. The platform 19 is used to place the verification block 20, and the verification block 20 is positioned on the platform 19 by the positioning component 21. The platform 19 provides a placement position for the verification block 20, and the positioning component 21 limits and fixes the verification block 20 on the platform 19, ensuring the stability and reliability of the pressure head 6. Foot pads 22 can also be provided at each corner of the bottom of the platform 19.

[0090] The positioning component 21 includes at least two positioning blocks 211 and at least one set of positioning elements 212. The positioning blocks 211 are disposed on the platform 19 and have positioning surfaces. Two of the positioning surfaces are used to engage with the opposite sides of the verification block 20. The positioning elements 212 include embedded positioning posts and positioning holes. One of the positioning posts and positioning holes is disposed on the platform 19, and the other is disposed on the verification block 20. The two positioning surfaces of the two positioning blocks 211 can provide initial positioning of the verification block 20. Combined with the engagement of the positioning posts and positioning holes, the reliability of the position of the verification block 20 can be ensured. Of course, having multiple sets of positioning components 21 can further improve the reliability and stability of the position of the verification block 20.

[0091] Furthermore, multiple positioning blocks 211 can be provided to cooperate with multiple different surfaces of the verification block 20. Of course, the positioning blocks 211 can also be irregularly shaped, meaning they have multiple positioning surfaces, each of which can cooperate with multiple surfaces of the verification block 20 to improve positioning effectiveness. For example, the positioning block 211 can be L-shaped, with two positioning surfaces forming an angle, which can cooperate with two surfaces of the verification block 20 respectively.

[0092] Furthermore, one of the positioning pins and positioning holes can be set on the platform 19, and the other on the calibration block 20. Positioning is achieved by inserting the positioning pin into the positioning hole. Alternatively, both the platform 19 and the calibration block 20 can have positioning holes, and then additional positioning pins can be inserted into both positioning holes on the platform 19 and the calibration block 20 simultaneously, thereby achieving the effect of positioning the calibration block 20 on the platform 19.

[0093] The platform 19 is also provided with a second adjustment module 23, which includes a third adjustment component 231 and a fourth adjustment component 232. The third adjustment component 231 is movably disposed on the platform 19 along the first direction; the fourth adjustment component 232 is movably disposed on the third adjustment component 231 along the second direction. The first direction, the second direction and the movement direction of the second mounting component 3 are perpendicular to each other. The movement direction of the second mounting component 3 is vertical. Therefore, the first direction and the second direction are two directions that intersect on the horizontal plane.

[0094] The movement of the third adjusting member 231 and the fourth adjusting member 232 can be achieved by a driver, such as a cylinder or an electric push rod. In this embodiment, the third adjusting member 231 and the fourth adjusting member 232 are connected by a positioning pin and a positioning hole, or by a screw and a threaded hole. For example, multiple threaded holes are provided at intervals along the first direction on the platform 19. The position of the third adjusting member 231 relative to the platform 19 is achieved by the cooperation of the screw with different threaded holes, thus realizing the movement of the third adjusting member 231 along the first direction. Similarly, the position of the fourth adjusting member 232 relative to the third adjusting member 231 is also achieved, thus realizing the movement of the fourth adjusting member 232 along the second direction.

[0095] The verification block 20 is placed on the fourth adjusting member 232. During the adjustment process of the third adjusting member 231 and the fourth adjusting member 232, the position of the verification block 20 is adjusted.

[0096] In summary, the pressure head detection device provided in this embodiment places the calibration block 20 on the fourth adjusting member 232 and fixes it by the positioning component 21. A pressure gauge 14 is placed on the calibration block 20. The piston rod of the driving cylinder moves downward, driving the pressure head 6 downward to press against the pressure gauge 14 for inspection. After the inspection, only the second mounting component 3 needs to be driven upward to remove the calibration block 20. Then, another calibration block 20 is placed on the fourth adjusting member 232. The second mounting component 3 moves downward under the restoring force of the elastic member 5, causing the pressure head 6 to press against the pressure gauge 14. If the height of the placed calibration block 20 is greater than the height required for this station, the second mounting component 3 will move towards the first mounting component 2 to press the pressure head 6 against the pressure gauge 14. In this case, the piston rod of the driving cylinder moves downward, and under the pressure of the pressure head 6 against the pressure gauge 14, the first connecting plate 15 and the second connecting plate 16 are separated by force, protecting the pressure head 6 of the pressure head detection device from damage. This pressure head detection device improves equipment stability, indirectly increasing production efficiency; it is also less prone to damage, indirectly saving costs; furthermore, the device enhances safety, ensuring that even misoperation or improper operation will not cause safety issues.
