Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of sensor detection equipment, in particular to a magnetic sensor detection tooling. Background Art
[0002] Reed switch is a special magnetic sensitive switch. It usually consists of two or three reed contacts made of both magnetic and conductive materials, which are encapsulated in a glass tube filled with inert gas or vacuum. The ends of the parallel reeds in the glass tube overlap and leave a certain gap or contact each other to form the normally open or normally closed contact of the switch; therefore, it is used as a sensor for counting, limit, etc.
[0003] After the reed switch is assembled, it needs to be inspected. In the prior art, workers usually hold a magnetic detector to approach the reed switch for inspection. This method is difficult to determine the trigger distance of the reed switch, resulting in large errors. Another method is to use a screw to drive the magnetic detector close to the reed switch. Although this method has a small error and can determine the trigger distance of the reed switch, it is complex in structure and has a high cost. Summary of the invention

[0024] The preferred embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings to further illustrate the present invention.
[0025] First, combine Figure 1~2 The magnetic sensor detection tooling according to the embodiment of the utility model is described, which is used to determine the trigger distance of the magnetic sensor 91 (with a built-in reed switch), or to perform fixed-distance trigger detection on the magnetic sensor 91 to judge good and defective products, and its application scenarios are very wide.
[0026] like Figure 1~2 As shown, the magnetic sensor detection tooling of the embodiment of the utility model comprises a base 1, a guide rail 2, a first card holder 3, a second card holder 4, a display module, a scale module and a power-on module.
[0027] Specifically, Figure 1~2As shown, the guide rail 2 is arranged on the top of the base 1 to facilitate the movement of the first card holder 3 and guide the movement of the first card holder 3.
[0028] Specifically, Figure 1~2 As shown, the first card holder 3 is slidably connected to the guide rail 2, and the first card holder 3 is used to fix the external magnet; the second card holder 4 is detachably arranged at one end of the guide rail 2, and is used to fix the magnetic sensor 91 to be detected. Alternatively, the first card holder 3 can be used to fix the magnetic sensor 91 to be detected, and the second card holder 4 can be used to fix the magnet.
[0029] Specifically, Figure 1~2 As shown, the display module is arranged on the base 1. The display module comprises: a lamp bead 51, which is arranged on the base 1 and is used to display the detection result. When the magnet on the first card holder 3 moves to a position where the magnetic sensor 91 on the second card holder 4 can be triggered, the magnetic sensor 91 is triggered, and the lamp bead 51 lights up. At this time, the distance between the first card holder 3 and the second card holder 4 is the trigger distance of the magnetic sensor 91.
[0030] Furthermore, in this embodiment, the display module also includes: a buzzer (not shown in the figure), which is arranged on the base 1 and is used to display the detection results. When the magnetic sensor 91 is triggered, the buzzer will make a sound to remind the detection personnel that the magnetic sensor 91 to be detected has been triggered and the magnet on the first card holder 3 has reached the trigger position.
[0031] Specifically, Figure 1~2 As shown, the scale module is arranged on the base 1. The scale module comprises: a scale line 61, which is arranged on the base 1 and parallel to the guide rail 2, and is used to display the distance between the first card seat 3 and the second card seat 4, so as to facilitate the viewing of the specific distance.
[0032] Specifically, Figure 1~2 As shown, the power-on module is arranged on the base 1, and the power-on module is connected to the display module and the magnetic sensor 91 to be detected, and is used to connect the display module and the magnetic sensor 91 to be detected. The power-on module includes: a power-on clip 71, which is arranged on the base 1, and is connected to the display module and the magnetic sensor 91 to be detected, and is used to clamp the power-on end of the magnetic sensor 91.
[0033] Further, if Figure 1~2 As shown, the magnetic sensor detection tooling of the embodiment of the utility model further includes: a pair of limit blocks 81, the pair of limit blocks 81 are respectively arranged at both ends of the guide rail 2, and the second holder 4 is detachably arranged on one of the limit blocks 81 to limit the formation of the first holder 3.
[0034] Further, if Figure 1~2As shown, the magnetic sensor detection tooling of the embodiment of the utility model further includes: a limiter 82, the limiter 82 is detachably arranged on the base 1, the limiter 82 is arranged vertically with the guide rail 2, the limiter 82 is located between the first card holder 3 and the second card holder 4, and the limiter 82 is used to limit the travel of the first card holder 3. When it is necessary to perform a fixed distance detection on the trigger distance of the magnetic sensor 91 to be detected, by fixing the limiter 82 at a specified position, the first card holder 3 can reach the specified distance each time, so as to judge whether the magnetic sensor 91 to be detected is a good product or a defective product. The limiter 82 can directly contact the first card holder 3 to achieve the limit of the first card holder 3, or the limiter 82 can contact the guide head 83 to indirectly achieve the limit of the first card holder 3.
[0035] Further, if Figure 1~2 As shown, the magnetic sensor detection tooling of the embodiment of the utility model further includes: an index head 83, which is arranged on the first holder 3, and the index head 83 indexes the scale line 61, so as to facilitate the observation of the position of the first holder 3, and the index head 83 can also cooperate with the limit member 82 to realize the limit of the stroke of the first holder 3.
[0036] Furthermore, in this embodiment, the indexing head 83 and the first holder 3 are integrally formed to improve strength and reliability.
[0037] When it is necessary to detect the trigger distance of the magnetic sensor 91, the limiter 82 is removed, the magnet is placed on the first card holder 3, the magnetic sensor 91 to be detected is placed on the second card holder 4, and the power-on end of the magnetic sensor 91 to be detected is connected to the power-on clip 71, and then the first card holder 3 is pushed to move toward the second card holder 4. When the lamp bead 51 lights up, the movement stops, and at this time, the distance between the first card holder 3 and the second card holder 4 is read through the scale line 61, and the specific value of the trigger distance of the magnetic sensor 91 to be detected can be determined.
[0038] When it is necessary to perform a fixed-distance detection on the trigger distance of the magnetic sensor 91, the limit member 82 is installed at the preset position, the magnet is placed on the first holder 3, the magnetic sensor 91 to be detected is placed on the second holder 4, and the energized end of the magnetic sensor 91 to be detected is connected to the energized clamp 71, and then the first holder 3 is pushed toward the second holder 4. When the first holder 3 moves to the position of the limit member 82, the lamp bead 51 has not lit up, then the magnetic sensor 91 to be detected is a defective product, if the lamp bead 51 lights up, then it is a good product.
[0039] Above, refer to Figure 1~2 The invention describes a magnetic sensor detection tooling according to an embodiment of the utility model, which has a simple structure, low manufacturing cost, convenient detection operation, and high detection accuracy.
