[0061] Example 1

[0062] This embodiment provides a positioning fixture for positioning the product 10 to be inspected, such as... Figure 1 As shown, the existing product 10 includes a product body 11, a rod 12, a first plate 13, and a second plate 14. The rod 12 is inserted into the product body 11, and the first plate 13 and the second plate 14 are welded to both ends of the rod 12. For ease of understanding, taking the product 10 as a coil as an example, the product body 11 is the coil body, the rod 12 is the coil core, and the first plate 13 and the second plate 14 are the first armature and the second armature, respectively. Next, the specific structure and implementation of this positioning fixture will be described in detail, with the up-down direction as the first direction, the left-right direction as the second direction, and the front-back direction as the third direction.

[0063] like Figures 2-6As shown, the positioning fixture 1000 includes a base plate 100, a positioning assembly 200, and a support assembly 300. The positioning assembly 200 includes a positioning member 210, which is elastically connected to the base plate 100 and can float along a first direction. The positioning member 210 is used to support the product body 11. The support assembly 300 includes support members 310 located on both sides of the positioning member 210 and arranged opposite to each other. The space formed by the positioning member 210 and the support members 310 is used to accommodate the product body 11 and the rod 12. The bottom end of the support member 310 is slidably disposed on the base plate 100 along a second direction, and the top end of the support member 310 can support and limit the first armature in the first direction. The first direction is perpendicular to the second direction. When coil testing is required, the coil is placed on the positioning member 210, and then the two support members 310 are manually pushed towards the positioning member 210. When the bottom end of the support member 310 slides along the base plate 100 to a position close to the rod 12, at least the top end of a portion of the support member 310 is located below the first armature. At this time, the top end of the support member 310 can support and limit the first armature in the first direction, ensuring that the first armature remains stationary when downward pressure is applied to the iron core, and the coil body and iron core can float in the first direction, effectively avoiding damage to the coil body, ensuring the reusability of the coil body, and the positioning fixture 1000 has a simple structure, is easy to operate, and can significantly improve testing efficiency.

[0064] Optionally, such as Figures 2-4 As shown, the positioning assembly 200 also includes an elastic element 220 and at least one guide rod 230. One end of the elastic element 220 is connected to the base plate 100, and the other end is connected to the positioning element 210 to provide elastic support. One end of the guide rod 230 is provided with a first limiting cap, and the other end of the guide rod 230 slides through the base plate 100 and is securely connected to the positioning element 210. The first limiting cap can fit against the bottom surface of the base plate 100. Through this structural design, the elastic element 220 ensures that the positioning element 210 has floating capability in the first direction, thereby buffering the impact of external forces on the coil body and effectively avoiding damage to the coil body. The guide rod 230, in conjunction with the first limiting cap, limits the floating range of the positioning element 210, ensuring the stability and accuracy of positioning and providing reliable support for the inspection of product 10.

[0065] Optionally, the elastic element 220 is a spring, which can provide reliable elastic support for the positioning element 210. The guide rod 230 is a first screw, one end of which is provided with a first limiting cap, and the other end is provided with an external thread. The threaded end of the first screw slides through the bottom edge and is threadedly connected to the support element 310. Optionally, the base plate 100 is provided with a first through hole 130, and the first screw is provided with a smooth rod portion. The smooth rod portion slides through the first through hole. The cooperation between the smooth rod portion and the first through hole 130 can reduce the frictional resistance of the first screw during the sliding process, thereby ensuring that the floating of the positioning element 210 in the first direction is smoother and more stable.

[0066] like Figure 4 As shown, in this embodiment, the positioning component 200 includes two first screws, which are located on both sides of the elastic member 220. Each first screw slides through the base plate 100 and is threadedly connected to the positioning member 210, thereby ensuring that the positioning member 210 is subjected to balanced forces and improving the reliability and accuracy of the detection results.

[0067] like Figure 2 and Figure 5 As shown, a second armature is provided at the second end of the iron core, and a protrusion 15 is formed by the protrusion of the second armature protruding from the iron core. A clearance groove 211 is provided on the positioning member 210 along the third direction. One end of the clearance groove 211 is provided with an opening 212, and the other end is provided with a positioning platform 213. When the coil body is placed, the opening 212 is used to allow the protrusion 15 to slide in the clearance groove 211. When the second armature at the bottom of the coil body slides to abut against the positioning platform 213, the coil body is placed in place, and the first direction, the second direction, and the third direction are perpendicular to each other. In this embodiment, the protrusion 15 is cylindrical, and the diameter of the protrusion 15 is equal to the width of the clearance groove 211. The sliding cooperation between the clearance groove 211 and the protrusion 15 can effectively guide the movement of the coil in the third direction, ensure reliable contact between the second armature and the positioning platform 213, and ensure the stability of the coil during the testing process. Optionally, the side of the coil where the second armature is mounted also has an inverted U-shaped part 16. When the coil body is placed on the positioning part 210, the inverted U-shaped part 16 is fastened to the positioning part 210 but does not contact the positioning part 210, so as to avoid mechanical damage to the positioning part 210.

[0068] Optionally, a slide rail 110 is provided on the base plate 100 along the first direction. The support member 310 includes a support base 311, a sliding part 3111 at the bottom of the support base 311, the sliding part 3111 being slidably disposed within the slide rail 110, and a supporting part 3112 at the top of the support base 311. At least a portion of the supporting part 3112 can fit against the bottom side of the first armature, thereby restricting the descent of the first iron core when downward pressure is applied to the iron core. The cooperation between the slide rail 110 and the sliding part 3111 ensures that the position of the support member 310 can be flexibly adjusted in the second direction. At least a portion of the supporting part 3112 can fit against the bottom side of the first armature. When downward pressure is applied to the iron core, the supporting part 3112 of the support member 310 restricts the descent of the first iron core, thereby achieving the limiting effect on the first armature and completing the test of the welding strength of the first armature and the iron core.

[0069] Optionally, the support member 310 further includes a limiting plate 312, which is disposed on the support portion 3112 of the support member 310. The limiting plate 312 has a limiting step 3120, which can abut against the two side walls adjacent to the first armature. The two limiting steps 3120 located on both sides of the positioning member 210 and arranged opposite each other can form a limiting space, in which at least part of the first armature can be confined. The limiting space can limit the first armature in a second direction, preventing the first armature from shifting or shaking due to external force. This precise limiting effect improves the positioning fixture 1000's ability to fix the first armature on the coil. At the same time, the synergistic effect of the support portion 3112 and the limiting plate 312 effectively fixes the position of the first armature, preventing it from shifting during the detection process, improving positioning accuracy, and enhancing the practicality and reliability of the positioning fixture 1000.

[0070] In this embodiment, as Figure 3 and Figure 5 As shown, the limiting step 3120 includes a first step wall 3121 and a second step wall 3122, which are perpendicular to each other. The first step wall 3121 and the second step wall 3122 respectively abut against the two side walls of the first armature, forming a right-angle limiting structure to ensure the stability of the first armature. Optionally, the limiting plate 312 is also provided with a clearance step 3130, which includes a third step wall 3123 and a fourth step wall 3124, which are perpendicular to each other and can form a right-angle clearance structure to avoid the outward protrusion of the first armature in the second direction.

[0071] Optionally, such as Figure 5 As shown, the support portion 3112 is provided with a clearance notch 31121. The clearance notch 31121 can prevent the support base 311 from contacting the iron core, avoid mechanical wear on the support portion 3112, and improve the service life of the support base 311.

[0072] Optionally, the base plate 100 has an elongated hole 120 extending in the second direction corresponding to the support member 310. The support assembly 300 also includes a first limiting rod 320. One end of the first limiting rod 320 slides through the corresponding elongated hole 120 and connects to the support member 310, while the other end can abut against the bottom side of the base plate 100. The cooperation between the elongated hole 120 and the first limiting rod 320 can limit the sliding range of the support member 310 in the second direction, allowing the support member 310 to flexibly adjust its position to adapt to different testing requirements. At the same time, the abutment between the first limiting rod 320 and the bottom side of the base plate 100 restricts the support member 310 from detaching from the base in the first direction, thereby ensuring the stability of the support member 310 in the vertical direction. This dual limiting design not only improves the adaptability and operational flexibility of the positioning fixture 1000, but also enhances the stability of the support member 310, avoiding testing errors caused by excessive sliding or detachment.

[0073] Optionally, such as Figure 5 and Figure 6 As shown, the support assembly 300 also includes a second limiting rod 330. The second limiting rod 330 can pass through the support member 310 and be inserted into the corresponding elongated hole 120. The first limiting rod 320 and the second limiting rod 330 can respectively abut against the two ends of the same elongated hole 120, which can ensure that the support member 310 remains fixed relative to the base, thereby improving the stability and reliability of the support and limiting of the first armature.

[0074] In this embodiment, the first limiting rod 320 is a limiting screw, which passes through the elongated hole 120 and is threadedly connected to the sliding part 3111 of the support base 311; the second limiting rod 330 is a limiting pin, and the sliding part 3111 of the support base 311 has a second through hole 31111, through which the limiting pin can be inserted into the elongated hole 120, and together with the corresponding limiting screw, it limits one support member 310, thereby improving detection efficiency. The limiting screw and the limiting pin work together, which not only improves the positioning accuracy and anti-displacement capability of the support assembly 300, but also simplifies the operation process, thereby improving detection efficiency.

[0075] Example 2

[0076] This embodiment provides a pressure detection device, such as... Figures 7-9As shown, the pressure detection device includes a power assembly 600 and a positioning fixture 1000 as described in Embodiment 1. The positioning fixture 1000 is used to position the product 10, and the power assembly 600 is used to apply pressure to the iron core in a first direction and record the pressure value applied when the iron core separates from the first armature. The positioning fixture 1000 can stably support the coil body and protect the coil body from damage. At the same time, the power assembly 600 accurately applies pressure and records the pressure value when the first armature separates from the iron core in real time, thereby realizing quantitative detection of the welding quality of the first armature and the iron core. This not only significantly improves the detection accuracy and efficiency, but also provides a reliable basis for coil quality evaluation through data recording.

[0077] Optionally, such as Figure 8 As shown, the pressure detection device also includes a housing 500, a positioning fixture 1000 mounted on the bottom wall of the housing 500, and a power assembly 600 including a drive unit 610, a pressure sensor 620, and a punch 630. The drive unit 610 is connected to the top wall of the housing 500, the pressure sensor 620 is mounted on the output end of the drive unit 610, and the punch 630 is connected to the pressure sensor 620. The drive unit 610 drives the punch 630 to abut against the iron core. The drive unit 610 provides stable power output, the pressure sensor 620 monitors and records the pressure value applied to the iron core by the punch 630 in real time, and the punch 630 ensures that the pressure is accurately applied to the iron core, realizing accurate testing of the welding strength between the iron core and the first armature. The high sensitivity of the pressure sensor 620 ensures accurate acquisition of the separation force value, thereby improving the reliability and data credibility of the detection. Meanwhile, this component, in conjunction with the non-destructive support function of the positioning fixture 1000, not only improves the inspection efficiency but also effectively avoids secondary damage to the product 10, meeting the requirements of high-quality inspection. In this embodiment, the driving component 610 is a servo electric cylinder, which provides stable driving force and precise displacement, thus improving inspection accuracy.

[0078] Optionally, such as Figure 8 As shown, a box body 500 has an entrance on one side, with a safety door 540 and an access control sensor 550 at the entrance. The safety door 540 can slide to a preset position in a first direction. The access control sensor 550 is communicatively connected to the drive unit 610. The access control sensor 550 is used to restrict the movement of the drive unit 610 when the safety door 540 is open, thereby effectively preventing safety accidents caused by misoperation or accidental opening. This safety protection mechanism not only improves the operational safety of the pressure detection device but also ensures the stability and reliability of the detection process.

[0079] Optionally, the access control sensor 550 includes a trigger and a sensor body. The sensor body is mounted on the bottom wall of the housing 500 and is communicatively connected to the drive unit 610. The trigger is mounted on the safety door 540. When the safety door 540 is closed, the trigger is electrically connected to the sensor body. When the safety door 540 is opened, the trigger separates from the sensor body, disconnects the electrical connection, and quickly sends a signal to the drive unit 610 to restrict its operation, thereby preventing the power unit 600 from operating in an unsafe state and effectively improving the safety of the pressure detection device.

[0080] Optionally, such as Figure 8 As shown, the housing 500 includes a frame 510, which includes a first mounting plate 511, a second mounting plate 513, and a support rod 512. The first mounting plate 511 and the second mounting plate 513 are arranged opposite each other along a first direction. Multiple support members 310 are located between the first mounting plate 511 and the second mounting plate 513. One end of the support rod 512 is connected to the first mounting plate 511, and the other end is connected to the second mounting plate 513. That is, the first mounting plate 511 is the bottom wall of the housing 500, and the second mounting plate 513 is the top wall of the housing 500. Thus, the positioning fixture 1000 is mounted on the first mounting plate 511, and the driving member 610 is mounted on the second mounting plate 513. The frame 510 provides a higher strength support structure, ensuring the reliability and accuracy of the test results. Figure 9 As shown, in this embodiment, a recessed groove 5111 is provided on the bottom surface of the first mounting plate 511 corresponding to the elongated hole 120. The size of the recessed groove 5111 is slightly larger than the size of the elongated hole 120 so that the head of the limiting screw does not protrude from the lower surface of the first mounting plate 511, thus ensuring the stability of the frame 510.

[0081] Optionally, the enclosure 500 further includes two side panels 520 and a back panel 530. The two side panels 520 are respectively disposed on both sides of the frame 510, and the back panel 530 is disposed on the rear side of the frame 510. The safety door 540 is located on the front side of the frame 510 and is slidably connected to the two side panels 520. In this embodiment, the two side panels 520 and the back panel 530 are made of stainless steel, and the safety door 540 is made of transparent acrylic sheet. The stainless steel side panels 520 and the back panel 530 have excellent corrosion resistance and mechanical strength, which can effectively protect the internal structure of the enclosure 500 and improve the durability and stability of the enclosure 500. The safety door 540 made of transparent acrylic sheet is both lightweight and highly transparent, which makes it easy for operators to observe the detection process inside the enclosure 500 in real time, while maintaining sufficient strength to cope with daily use. In this embodiment, the two side panels 520 and the back panel 530 are integrally bent and formed, which can improve the manufacturing efficiency of the enclosure 500.

[0082] Optionally, the safety door 540 is provided with a ball handle 542 to facilitate the opening and closing of the safety door 540. The ball handle 542 provides the operator with a comfortable gripping experience, making the sliding operation of the safety door 540 more effortless and smooth, simplifying the opening and closing process of the safety door 540 and improving operating efficiency.

[0083] Optionally, one of the safety door 540 and the housing 500 is provided with a guide portion 541 extending along the first direction, and the other of the safety door 540 and the housing 500 is provided with a mating portion 521. The guide portion 541 can slide with the mating portion 521. The sliding engagement between the guide portion 541 and the mating portion 521 ensures smooth movement of the safety door 540 along the first direction. The combination of the pulley and the sliding hole further reduces sliding friction, improving the smoothness and durability of the opening and closing of the safety door 540.

[0084] In this embodiment, as Figure 8 As shown, the side plate 520 of the housing 500 has sliding holes, and the safety door 540 has pulleys corresponding to the sliding holes. The pulleys can slide and connect with the side wall of the sliding holes. Specifically, the safety door 540 is equipped with four pulleys on the side facing the housing 500, that is, two pulleys are provided on the left side of the safety door 540 and two pulleys are provided on the right side. The two pulleys on the left side are slidably set in the guide holes of the left side plate 520 of the housing 500, and the two pulleys on the right side are slidably set in the guide holes of the right side of the housing 500, thereby ensuring the smooth sliding of the safety door 540.

[0085] In other embodiments, the specific forms of the guide part 541 and the mating part 521 can be adjusted according to actual needs. For example, a guide rail can be provided on the safety door 540 and a guide block can be provided on the side plate 520 of the housing 500. The guide block and the guide rail slide together, thereby improving the stability of the sliding of the safety door 540.

[0086] Optionally, such as Figure 8 As shown, the pressure detection device also includes a limiting component 700, which includes a first limiting member 710 and a second limiting member 720. The first limiting member 710 is disposed on the housing 500, and the second limiting member 720 is disposed on the safety door 540. The first limiting member 710 can be magnetically connected or snap-fitted to the second limiting member 720. With this design, when the safety door 540 slides to the open position, the magnetic connection or snap-fit ​​connection between the first limiting member 710 and the second limiting member 720 can effectively lock the safety door 540, preventing it from accidentally falling and protecting the operator from injury, thus improving operational safety.

[0087] In this embodiment, the first limiting member 710 is a first magnet, and the second limiting member 720 is a second magnet or an iron component. When the safety door 540 is opened to the correct position, the first magnet can be attracted to the second magnet, or the iron component can be attracted to the first magnet. In this embodiment, to facilitate the installation of the first magnet on the housing 500, the limiting assembly 700 also includes a bracket 730. The bracket 730 is an L-shaped bracket 730, with one side fixed to the housing 500 and the first magnet installed on the other side. The bracket 730 provides an installation position for the first magnet, facilitating the attraction between the first and second magnets and ensuring greater stability when the safety door 540 is opened.

[0088] In other embodiments, the first limiting member 710 can be a buckle, and the second limiting member 720 can be a slot. When the safety door 540 is opened to the position, the buckle is engaged in the slot, thereby preventing the safety door 540 from falling and improving the safety of operation.

[0089] Optionally, the pressure testing device also includes a frame 400 and a display component 800. Both the housing 500 and the display component 800 are located on top of the frame 400. The display component 800 is communicatively connected to the pressure sensor 620 and the drive unit 610, and is used to display the test results. The frame 400 provides a stable support platform for the housing 500 and the display component 800, ensuring the overall structural stability of the device. Simultaneously, the display component 800, communicatively connected to both the pressure sensor 620 and the drive unit 610, can intuitively display test data such as the pressure value applied when the iron core separates from the first armature, facilitating real-time monitoring of the testing process by operators and improving data readability.

[0090] In this embodiment, the display component 800 includes a support rod 810 and a display screen 820. One end of the support rod 810 is connected to the top of the frame 400, and the other end is equipped with the display screen 820. The display screen 820 is communicatively connected to the pressure sensor 620 and the drive unit 610, and can display the detection results. Placing the display component 800 on top of the frame 400 optimizes the human-machine interaction experience, facilitates operators to observe and record results, and further improves the practicality and work efficiency of the pressure detection device.

[0091] Optionally, the pressure detection device provided in this embodiment can not only achieve accurate pressure detection, but also serve as a coil breaking device. For example, when it is necessary to break the first armature on the coil body, the power component 600 applies pressure along the first direction to the iron core, and combined with the stable support of the positioning clamp 1000, the defective welded product 10 can be broken apart. By integrating detection and breaking into one unit, not only is work efficiency improved, but the use of additional tools is also reduced, the complexity and cost of operation are lowered, and the practicality and flexibility of the pressure detection device are improved. It should be noted that, according to the coil model, a matching support member 310 can be installed on the base plate 100 to adapt the support member 310 to the first armature of different coil models, ensuring that the positioning clamp 1000 can stably support and limit the products 10 of various specifications, thus improving the compatibility of the positioning clamp 1000.

[0092] For example, taking the pressure detection device provided in this embodiment to test the welding strength between the coil core and the first armature as an example, the detection process is roughly as follows:

[0093] S1. The operator manually holds the ball head handle 542 and opens the acrylic safety door 540 upwards, disconnecting the access control sensor 550. At this time, the detection function cannot be activated. When the safety door 540 is pushed upwards until the first limit member 710 and the second limit member 720 are aligned, the first limit member 710 and the second limit member 720 are magnetically attracted, restricting the safety door 540 from falling.

[0094] S2. The operator opens the two support members 310 to both sides. The first limiting rod 320 on the bottom side of the support member 310, together with the elongated hole 120, can prevent the support member 310 from being moved out by accident and causing danger. Then, the second armature of the coil is placed on the positioning member 210 in the correct direction, and the coil body is pushed inward into place (the second armature abuts against the positioning platform 213). The clearance groove 211 on the positioning member 210 restricts the left and right movement of the part of the iron core protruding from the second armature. The positioning member 210 is slidably connected to the base plate 100 by two first screws of equal height, which plays a pre-compression role on the spring.

[0095] Then, the operator closes the two support members 310 on both sides of the positioning member 210 towards the coil body. After they are closed, the first armature of the coil will be lifted above the two supporting parts 3112 of the two support members 310. At this time, the limiting space formed by the two limiting plates 312 provides secondary positioning for the first armature. The operator inserts the second limiting rod 330 into the second through hole 31111 and the elongated hole 120. The first limiting rod 320 and the second limiting rod 330 respectively abut against the two ends of the same elongated hole, restricting the movement of the support member 310 on the base plate 100, thus fixing the support member 310 and preventing the two support members 310 from shifting during testing.

[0096] S3. The operator holds the ball handle 542 to close the safety door 540. The metal plate on the safety door 540 triggers the access control sensor 550. Then, the operator presses the start button of the servo cylinder. The servo cylinder operates according to the set program, with the punch 630 pressing down on the iron core. The pressure is continuously increased until the weld between the iron core and the first armature is torn and destroyed. The punch 630 descends to the designated distance. The positioning component 210 moves with the pressing distance to protect the coil body from damage. The pressure sensor 620 records the highest pressure value when the weld between the iron core and the first armature is torn and destroyed. Then, the servo cylinder, along with the punch 630 and the pressure sensor 620, quickly returns to the original position. The positioning component 210 returns to its original position under the action of the spring. The pressure sensor 620 transmits the highest data and saves it to the display screen 820, indicating whether it is qualified.

[0097] S4. The operator opens the safety door 540 and disconnects the access control sensor 550. At this time, the servo cylinder cannot be started. The second limit rod 330 is taken out, and the two support pieces 310 are pushed to the sides to remove the separated coil body and the first armature.

[0098] S5. When testing the next coil, repeat steps S1, S2, S3, and S4 to complete the testing function. After the sampling inspection of a batch of products 10 is completed, close the safety door 540 and turn off the power to the pressure detection device.
