Description

Technical Field

[0001] This utility model relates to the field of contactor manufacturing technology, and in particular to a contactor adjustment device. Background Technology

[0002] A contactor is an automatic switching electrical device used to frequently connect or disconnect AC / DC main circuits and high-capacity control circuits. It is mainly used to control motors, electric heating equipment, welding machines, etc., and is one of the most widely used electrical components in electric drive systems. Contactors have two states: on and off, called the released state and the operating state. Contactors include DC contactors and AC contactors.

[0003] The main working components of an AC contactor are a low-voltage coil and an armature. It can be divided into single-phase and three-phase contactors. When the coil is energized, the stationary iron core generates electromagnetic attraction, which attracts the moving iron core. Since the contact system is linked with the moving iron core, the moving iron core drives the three moving contact pieces to run simultaneously, closing the contacts and thus connecting the power supply. When the coil is de-energized, the attraction disappears, and the linkage part of the moving iron core separates by the reaction force of the torsion spring, causing the main contacts to open and thus cutting off the power supply. Because different customers use AC contactors and their application scenarios vary, the required reaction force of the AC contactor's torsion spring differs depending on the application scenario. In such cases, operators need to manually adjust the reaction force of the AC contactor's torsion spring to achieve the required product performance. However, manual adjustment has problems such as inaccurate reaction force and low operational efficiency. Furthermore, if the pressure of the torsion spring is insufficient, it will cause abnormal contactor engagement; if the reaction force of the torsion spring is too large, it will cause slow engagement; if the contact spring pressure exceeds the travel limit, the iron core cannot be fully closed; and if the contact spring pressure and release pressure are too large, the contacts cannot be fully closed.

[0004] Therefore, there is an urgent need to provide a new type of contactor adjustment device to solve the above-mentioned technical problems in the prior art. Utility Model Content

[0005] The purpose of this utility model is to provide a contactor adjustment device that can automatically identify the magnitude of the reaction force during the adjustment of the torsion spring reaction force value, thereby improving the accuracy and efficiency of the contactor reaction force adjustment, and is applicable to contactors of different models.

[0006] To achieve this objective, the present invention adopts the following technical solution:

The locking part is located below the limiting gear and protrudes towards the limiting gear. The operating part is rotatably connected to the first mounting base. Rotating the operating part drives the locking part to approach or move away from the limiting gear, so that the locking part engages with the tooth groove of the limiting gear or disengages from the tooth groove of the limiting gear. An elastic member is sandwiched between the lower part of the locking part and the first mounting base.

[0033] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

[0034] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0035] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0036] In the description of this embodiment, the terms "upper," "lower," "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0037] The first direction described in this embodiment is: Figure 2 and Figure 5 The X direction shown is the horizontal direction and the axial direction of the long axis 11 of the contactor 10 to be adjusted; the second direction is... Figure 5 The Y direction shown is another horizontal direction perpendicular to the X direction; the third direction is... Figure 2 and Figure 5 The Z direction shown is the vertical direction, where the X, Y, and Z directions are all perpendicular to each other.

[0038] In this embodiment, the contactor 10 to be adjusted is an AC contactor, which will not be described in detail here.

[0039] like Figure 1 and Figure 2 As shown, the contactor adjustment device includes an adjustment base 100, a force measuring component 200, a fixing component 300, and an adjustment component 400. The adjustment base 100 is used to support the contactor 10 to be adjusted. The fixing component 300 is disposed on the adjustment base 100 and moves along a first direction. The adjustment component 400 is disposed on the adjustment base 100 and spaced apart from the fixing component 300 in the first direction. The space between the adjustment component 400 and the fixing component 300 is used to place the contactor 10 to be adjusted. The fixing component 300 is used to move along the first direction and abut against one end of the long shaft 11 of the contactor 10 to be adjusted. The output end of the adjustment component 400 is connected to the other end of the long shaft 11. The adjustment component 400 is used to drive the long shaft 11 to rotate around its own axis to adjust the reaction force value of the torsion spring 12 disposed on the long shaft 11. The force measuring component 200 is connected to the adjustment base 100 and is used to detect the reaction force value of the torsion spring 12.

[0040] In this embodiment, the contactor 10 to be adjusted is placed along a third direction. Specifically, the mounting structure at the bottom of the contactor 10 is placed on the top wall of the adjusting base 100, and the contactor 10 to be adjusted is fixed in the snap-fit ​​groove 120 of the adjusting base 100 using fixing bolts. Furthermore, the adjusting base 100 is provided with a plurality of snap-fit ​​grooves 120 for fixing the contactor 10 to be adjusted. The number and shape of the snap-fit ​​grooves 120 can be selected according to the model of the contactor 10 to be adjusted, which will not be elaborated here; specifically, there are 4 snap-fit ​​grooves 120, each of which extends along a second direction, thereby accommodating contactors 10 of different sizes and models to be adjusted.

[0041] In this embodiment, the contactor adjustment device uses an adjustment base 100 to support the contactor 10 to be adjusted. The contactor 10 to be adjusted has a fixing component 300 and an adjustment component 400 at both ends along a first direction. The fixing component 300 can be adjusted in position along the first direction. The fixing component 300 abuts against the contactor 10 to be adjusted along the first direction, clamping and fixing the contactor 10 to be adjusted with the adjustment component 400. This makes the contactor adjustment device suitable for contactors 10 of different sizes and models. At this time, the adjustment component 400 drives the long shaft 11 of the contactor 10 to rotate around its own axis, causing the long shaft 11 to drive the torsion spring 12 mounted on it to contract or extend, thereby adjusting the reaction force value of the torsion spring 12. During the adjustment process, the force measuring component 200 can directly measure the reaction force value, thus visually demonstrating whether the reaction force value of the torsion spring 12 meets the requirements after adjustment. This achieves automatic adjustment of the reaction force value of the contactor 10 to be adjusted, improving the accuracy and efficiency of the adjustment. This contactor adjustment device can automatically identify the magnitude of the reaction force during the adjustment of the torsion spring 12, thereby improving the accuracy and efficiency of the contactor's reaction force adjustment. It is also applicable to contactors of different models.

[0042] Optionally, the force measuring component 200 includes a support frame 210 and a force gauge 220. The support frame 210 is fixed to the adjustment base 100, and the force gauge 220 is disposed on the support frame 210. The force gauge 220 is used to abut against the contactor 10 to be adjusted in the open position and to measure the reaction force value received by the contactor 10 to be adjusted. It should be noted that during the test, the contactor 10 to be adjusted is in the open state. The force gauge 220 moves along the third direction and presses the contactor downward, causing the contactor to move to the closed position, thereby compressing the torsion spring 12 to give it the adjusted reaction force value. The force gauge 220 can accurately measure the reaction force value. The structure is simple and can also improve the accuracy of force measurement.

[0043] In this embodiment, the adjustment component 400 moves along the first direction on the adjustment base 100. Thus, both the adjustment component 400 and the fixing component 300 can change position along the first direction, making the contactor adjustment device more applicable to a wider range of sizes, including both larger and smaller contactors 10 to be adjusted; further details will not be elaborated here.

[0044] like Figures 1 to 4As shown, optionally, the adjustment base 100 is provided with a plurality of mounting holes 110 on both sides of the contactor 10 to be adjusted along the first direction. Each mounting hole 110 extends along the first direction, and the plurality of mounting holes 110 on each side are spaced apart along the second direction. The fixing component 300 is connected to the mounting hole 110 on one side, and the adjustment component 400 is connected to the mounting hole 110 on the other side. In this embodiment, four mounting holes 110 are provided. The fixing component 300 is installed in two parallel mounting holes 110, and the adjusting component 400 is installed in the other two parallel mounting holes 110. By moving the positions of the fixing component 300 and the adjusting component 400, and then passing the connector through the adjusting component 400 or the fixing component 300 and the corresponding mounting hole 110 in sequence, the adjusting component 400 and the fixing component 300 can be installed at different positions in the mounting holes 110, thereby realizing the adjustment and fixing of the fixing component 300 and the adjusting component 400 along the first direction. The position adjustment method is simple and the fixing effect is better.

[0045] like Figure 3 As shown, the fixing component 300 in this embodiment includes a second mounting base 310, a driving mechanism, and a fixing rod 320. The second mounting base 310 is connected to the adjusting base 100. The driving mechanism is disposed on the second mounting base 310. The fixing rod 320 is slidably connected to the second mounting base 310 along a first direction. One end of the fixing rod 320 is connected to the output end of the driving mechanism. The driving mechanism is used to drive the fixing rod 320 to move along the first direction, so that the other end of the fixing rod 320 can abut against the long shaft 11. It should be noted that the driving mechanism can be a manual operating mechanism or an automated driving component such as a driving cylinder or a driving motor, as long as it can realize the movement of the fixing rod 320 along the first direction. The fixing rod 320 abutting against the long shaft 11 can limit and fix the long shaft 11. Specifically, a bearing can be set on the fixing rod 320, and the long shaft 11 is correspondingly inserted into the bearing to realize the axial and radial limit and fixation of the long shaft 11. This will not be elaborated here.

[0046] Specifically, in this embodiment, the aforementioned driving mechanism is a manual operating mechanism, including a rotating handle 331 and a transmission hinge 332. The rotating handle 331 is hinged to the second mounting base 310, one end of the transmission hinge 332 is hinged to one end of the rotating handle 331, and the other end of the transmission hinge 332 is hinged to the fixed rod 320. By rotating the rotating handle 331, the transmission hinge 332 at the bottom of the rotating handle 331 can be driven to move along the first direction, thereby driving the fixed rod 320 to move along the first direction, realizing the fixing or unfixing of the fixed rod 320 and the long shaft 11. Compared with the setting of automated driving components, this simplifies the structure and reduces costs.

[0047] Furthermore, a second mounting bracket 311 may also be provided on the second mounting base 310. The second mounting bracket 311 is equipped with the aforementioned drive mechanism and fixing rod 320. The second mounting bracket 311 and the second mounting base 310 can be integrally formed or can be separately detached, which will not be elaborated here.

[0048] like Figure 4 and Figure 5 As shown, the adjustment assembly 400 includes a first mounting base 410, an adjustment shaft 420, and a limiting mechanism 430. The first mounting base 410 is connected to the adjustment base 100. The adjustment shaft 420 is rotatably connected to the first mounting base 410. One end of the adjustment shaft 420 is used to connect to the long shaft 11, and the other end of the adjustment shaft 420 is provided with an adjustment handle 422. The adjustment shaft 420 rotates to drive the long shaft 11 to rotate. The limiting mechanism 430 is provided on the first mounting base 410. When adjusting the reaction force value of the torsion spring 12, the limiting mechanism 430 is disconnected from the adjustment shaft 420. After the reaction force value of the torsion spring 12 is adjusted to a preset value, the limiting mechanism 430 brakes the adjustment shaft 420. In this embodiment, bearings are provided at both ends of the adjusting shaft 420, and the bearings are fixed on the mounting base, thereby enabling the adjusting shaft 420 to rotate smoothly. By manually rotating the adjusting handle 422, the adjusting shaft 420 is driven to rotate, which in turn drives the long shaft 11 to rotate, thereby adjusting the reaction force value of the torsion spring 12 on the long shaft 11. When the adjustment is in place, the adjusting shaft 420 is braked by the limiting mechanism 430, so that the torsion spring 12 remains stationary at this moment, which facilitates the subsequent reaction force value detection work and makes the measured reaction force value more accurate.

[0049] like Figure 5As shown, in this embodiment, the limiting mechanism 430 includes a limiting gear 431 and a limiting block 432. The limiting gear 431 is coaxially fixed to the adjusting shaft 420, and the limiting block 432 is disposed on the first mounting base 410. The limiting block 432 is used to move closer to or further away from the limiting gear 431, so that the limiting block 432 engages or disengages with the tooth groove of the limiting gear 431. The limiting gear 431 is coaxially fixed to the adjusting shaft 420, meaning it can rotate together with the adjusting shaft 420. When the adjustment is in place, the limiting block 432 moves closer to the limiting gear 431, and the limiting block 432 can engage with the limiting gear 431, thus fixing the limiting gear 431. This, in turn, achieves braking of the adjusting shaft 420. The operation is convenient and the structure is simple, which can reduce manufacturing costs.

[0050] In a preferred embodiment, the limiting block 432 has an operating part 4322 extending out of the first mounting base 410 at one end along the second direction, and a locking part 4321 at the other end. The locking part 4321 is located below the limiting gear 431 and protrudes towards the limiting gear 431. The operating part 4322 is rotatably connected to the first mounting base 410. Rotating the operating part 4322 drives the locking part 4321 to approach or move away from the limiting gear 431, so that the locking part 4321 can engage with the tooth groove of the limiting gear 431 or disengage from the tooth groove of the limiting gear 431. An elastic member 433 is sandwiched between the lower part of the locking part 4321 and the first mounting base 410. When it is necessary to rotate the adjusting shaft 420, lift the operating part 4322, and the locking part 4321 will press down the elastic member 433 and move away from the tooth groove of the limiting gear 431, thus disengaging the connection between the two. After the adjusting shaft 420 is adjusted to the correct position, release the operating part 4322, and the locking part 4321 will move upward under the elastic force of the elastic member 433, so that the locking part 4321 can engage with the tooth groove of the limiting gear 431, thereby braking the adjusting shaft 420, further improving the convenience of operation and the adjustment efficiency.

[0051] In other optional embodiments, the limiting block 432 is slidably connected to the first mounting base 410. One end of the limiting block 432 is provided with an elastic element 433, and the other end can engage with the tooth groove of the limiting gear 431. In specific operation, by pushing the limiting block 432 away from the limiting gear 431 in the second direction, the elastic element 433 can be compressed, and the other end of the limiting block 432 is released from engagement with the limiting gear 431. After the reaction force value is adjusted, the limiting block 432 is released, and the elastic element 433 pushes the limiting block 432 closer to and against the tooth groove of the limiting gear 431, thereby braking the limiting gear 431 and the adjusting shaft 420.

[0052] In another optional embodiment, the limiting mechanism 430 is a clamping and fixing structure provided on the first mounting base 410, such as an elastic gripper, a disc brake, or a drum brake. The elastic gripper directly clamps and fixes the adjusting shaft 420 to achieve braking. The disc brake uses the contact friction between the brake disc and the brake caliper to achieve braking. The drum brake uses the contact friction between the brake shoes and the brake drum to achieve braking. All of the above structures can achieve braking of the adjusting shaft, which will not be described in detail here.

[0053] In this embodiment, an adjustment part 421 is provided at one end of the adjustment shaft 420 near the contactor 10 to be adjusted, which cooperates with the adjustment block 13 of the long shaft 11. The adjustment part 421 and the adjustment shaft 420 can be integrally formed or can be separately and detachably provided. Using the adjustment part 421 to fix the adjustment block 13 can improve the fixing effect between the adjustment shaft 420 and the adjustment block 13, provide a stable torque to rotate the long shaft 11, and further improve the adjustment efficiency.

[0054] Furthermore, a first mounting support 411 may also be provided on the first mounting base 410. The first mounting support 411 is equipped with the aforementioned adjusting shaft 420 and limiting mechanism 430. The first mounting support 411 and the first mounting base 410 can be integrally formed or can be separately detached. This will not be elaborated here.

[0055] like Figure 6 and Figure 7 As shown, this embodiment also provides a contactor detection device and detection method. The detection device includes a cabinet 20, which is equipped with a control panel 23, a detector mounting position 24 (for installing the detector), and at least two test positions, specifically a first test position 21 and a second test position 22. The control panel 23 is equipped with a PLC control unit, which is used to select different test positions, set withstand voltage and contact detection parameters, etc.

[0056] During testing, first, select the corresponding test station according to the product specifications, place the product in the corresponding test station, turn on the main power switch, and select the product specifications and withstand voltage parameters on the control panel 23; the built-in barcode scanner of the testing device scans the product barcode. If there is no abnormality, the testing will start automatically and the test data will be recorded. The power-on test, withstand voltage test, and parameter test will be performed in sequence. If an abnormality is detected during the testing process, the corresponding fault information will be displayed, and the faulty product will be removed simultaneously while the test data will be recorded and transmitted; if the test is normal, the test data will also be recorded and transmitted.

[0057] Furthermore, during the test, different detection statuses are displayed on the control panel 23 using indicator lights of different colors. Different fault information corresponds to different colored indicator lights, which makes it easier for operators to intuitively understand the fault information and take corresponding actions. This will not be elaborated further here.

[0058] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here.
