Description

Technical Field

[0001] This invention relates to the field of motor testing technology, and more specifically, to a constant pressure carbon brush spring pressure testing device for motor rotors. Background Technology

[0002] A generator rotor slip ring is a metal ring fixed on the generator rotor that can rotate at high speed with the rotor. A carbon brush is a brush holder mounted on the fixed part of the device. It is made of carbon blocks and is also called an electric brush. A spring is pressed on the upper end. The spring pressure contacts the slip ring. Current is input to the rotor winding through the wire connected to the carbon brush head, forming magnetic poles on the generator rotor and cutting the generator stator winding to generate electricity.

[0003] Traditional carbon brush spring pressure checks involve both visual and mechanical inspections. This necessitates pressure testing before installing the carbon brush springs on the motor to ensure the stability of the carbon brush spring pressure after installation.

[0004] For example, Chinese patent application number CN113916525A discloses a generator rotor slip ring carbon brush constant pressure spring pressure detection device, mainly relating to the field of generator testing equipment. It includes a base and a control system. A limiting ring is provided at the center of the base. A detection body is located between the outer wall of the limiting ring and the inner wall of the base. An annular groove is formed in the outer wall of the base, and a driving ring is provided within the groove. The outer side of the driving ring is threaded to the groove wall. The cross-section of the groove near the limiting ring is a stepped surface, and the bottom of the driving ring near the limiting ring has an inverted conical cross-section. The beneficial effects of this invention are: it eliminates manual measurement, improves the efficiency of spring pressure measurement, reduces labor intensity, and allows measurement under simulated use conditions, reducing measurement errors. It can also detect carbon brush deterioration as early as possible, avoiding equipment damage accidents.

[0005] The aforementioned carbon brush constant pressure spring pressure testing device can test the lateral pressure of the constant pressure spring through the contact test of the limiting plate. However, because the constant pressure spring is helically coiled, it is impossible to fully detect the pressure of the constant pressure spring when it is subjected to lateral pressure. Furthermore, after the spring undergoes a certain deformation under pressure, the traditional testing method requires manual judgment of the deformation range of the spring under pressure, which makes it impossible to monitor and control the deformation of the spring in a timely manner. This affects the timely detection of the pressure deformation of the constant pressure spring after pressure testing, thus hindering efficient detection and processing of the constant pressure spring during pressure testing. Therefore, it is of great significance to study a constant pressure carbon brush spring pressure testing device for motor rotors to solve the above problems. Summary of the Invention

[0006] To overcome the aforementioned deficiencies of the prior art, this invention provides a pressure detection device for constant pressure carbon brush springs used in motor rotors. The technical problem this invention aims to solve is that, when performing spring pressure testing, the lateral pressure of the constant pressure spring can be tested through the contact test of the limiting plate. However, because the constant pressure spring is helically coiled, the pressure of the constant pressure spring cannot be fully detected when it is subjected to lateral pressure. Furthermore, when the spring undergoes a certain deformation under pressure, traditional detection methods require manual judgment of the deformation range of the spring under pressure, making it impossible to monitor and control the deformation of the spring in a timely manner. This affects the timely detection of the pressure deformation of the constant pressure spring after pressure testing, thus hindering efficient detection and processing of the constant pressure spring during pressure testing.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a constant pressure carbon brush spring pressure detection device for motor rotor, comprising a mounting plate, a control surface, and movable testing mechanisms. The top of the mounting plate is provided with a control surface, and multiple movable testing mechanisms are mounted on the top of the control surface.

[0009] The active testing mechanism includes a movable chute, a contact connecting plate, a sliding rod, a first limiting plate, a first rotating seat, and a connecting movable seat. The movable chute is located outside the top of the control panel. The contact connecting plate is located at the top of the control panel. The sliding rod is rotatably connected to the top of the contact connecting plate. The first limiting plate is fixedly connected to the outer side wall of the contact connecting plate. The first rotating seat is inserted outside the bottom of the first limiting plate. The connecting movable seat is fixedly connected to the outer side wall of the top of the control panel.

[0010] As a further embodiment of the present invention: the sliding rod is inserted through the inside of the movable slide groove, the sliding rod is slidably connected inside the movable slide groove, the first limiting plate is rotatably connected to the top of the control panel through the first rotating seat, and the sliding rod rotates around the first rotating seat in the circumference inside the movable slide groove.

[0011] As a further aspect of the present invention: the movable extension mechanism includes a second rotating seat, a rotating shaft, and a connecting extension rod. The second rotating seat is fixedly connected to the outer side wall of the abutting connecting plate. The rotating shaft is inserted inside the second rotating seat. The outer surface of the rotating shaft is connected to the connecting extension rod. One side wall of the connecting extension rod is fixedly connected to the outside of the transmission mechanism. The rotating shaft is rotatably connected inside the second rotating seat.

[0012] As a further embodiment of the present invention: the transmission mechanism includes a movable motor, a movable rotating tooth and a plurality of connecting gears. The movable motor is disposed above the control panel. The movable rotating tooth is fixedly connected to the outer wall of the output end of the movable motor. A plurality of connecting gears are meshed on the outside of the movable rotating tooth, and a plurality of connecting rack plates are meshed on the outside of each of the plurality of connecting gears.

[0013] As a further embodiment of the present invention: the connecting gears are evenly arranged on the outer side wall of the movable rotating teeth, the connecting rack plate is rotatably connected to the connecting gears, and a connecting top extension rod is fixedly connected to one side outer wall of the connecting rack plate.

[0014] As a further embodiment of the present invention: the detection mechanism includes an abutment plate, an elastic guide rod, and a connecting guide rod. The abutment plate is disposed inside the first limiting plate. An elastic guide rod is fixedly installed on one outer wall of the abutment plate. A connecting guide rod is fixedly connected to one outer wall of the abutment plate. A mounting base is fixedly connected to one side wall of the elastic guide rod. A pressure sensor is installed on the outside of the mounting base.

[0015] As a further embodiment of the present invention: one side of the connecting guide rod is inserted into the inside of the pressure sensor, and the pressure sensor is connected to the abutment plate through the connecting guide rod and the elastic guide rod. Two elastic guide rods are provided on the upper and lower sides of the outer side wall of the mounting base.

[0016] As a further embodiment of the present invention: the limiting and fixing mechanism includes a placement plate, a second limiting plate, and a bolt adjusting seat. The placement plate is fixedly connected to the top of the connecting movable seat. The top of the placement plate is provided with a second limiting plate. A bolt adjusting seat is inserted into the outside of the second limiting plate. An abutment seat is fixedly connected to one side wall of the bolt adjusting seat. A hanging rod is welded to the top of the second limiting plate. A carbon brush spring is sleeved on the outside of the second limiting plate. The bolt adjusting seat is threadedly connected to the second limiting plate. The hanging rod is sleeved on the outside of the top of the carbon brush spring. The connecting end of the carbon brush spring abuts against the outer side wall of the abutment plate.

[0017] The beneficial effects of this invention are as follows:

[0018] 1. This invention, through the setting of an active testing mechanism, a storage plate base, and a sliding plate, enables the carbon brush spring to be inserted outside the second limiting plate during pressure testing. After the bolt adjusting seat is screwed and rotated, the carbon brush spring can be limited and fixed outside the second limiting plate. Subsequently, after the transmission mechanism operates, it drives the connecting extension rod to extend the connecting plate. At this time, the sliding rod rotates around the first rotating seat inside the moving groove. Thus, when the connecting end of the carbon brush spring abuts against the abutting plate, the pressure sensor can detect the pressure during abutment. After the placement plate is connected to the top of the connecting active seat, the placement plate can rotate. Thus, when the core end of the carbon brush spring is fixed, the output end of the carbon brush spring is subjected to pressure after abutment, and the compressive elastic deformation of the carbon brush spring can be detected. Therefore, during the pressure test of the carbon brush spring, the working state of the carbon brush spring under pressure can be simulated to a great extent, increasing the accuracy and convenience of the test.

[0019] 2. This invention, through the setting of a storage plate base, a sliding plate, a measuring scale, and a clamping plate, enables the carbon brush spring to be inserted and limited after being inserted on the second limiting plate. First, the movable rotation between the clamping plate and the sliding plate, and the elastic extension and contraction between the clamping plate and the tension spring, allow the carbon brush spring to be engaged and limited. Subsequently, when the carbon brush spring unfolds under pressure, the outermost spring of the carbon brush spring is driven by the limiting of the clamping plate to slide and extend outward within the storage plate base. This allows the data of the sliding plate after outward movement to be monitored in a timely manner through the measuring scale. This facilitates the observation of the deformation value of the elastic displacement of the carbon brush spring after being subjected to pressure, and enables effective and convenient testing of qualified carbon brush springs.

[0020] 3. This invention, through the configuration of a movable motor, movable rotating gears, connecting gears, and connecting rack plates, enables synchronous testing of carbon brush spring components. The movable motor's operation causes the movable rotating gears to rotate, controlling the four connecting gears to rotate synchronously. Simultaneously, the connecting rack plates, after meshing with the connecting gears, control the synchronous extension and retraction of the four connecting rack plates. This, in turn, controls the extension operation of the connecting top extension rod on the rotating shaft and the extension control of the abutting connecting plate, thereby detecting the pressure at the connecting end of the carbon brush spring component. This allows for synchronous testing of multiple carbon brush spring components, increasing testing efficiency and enhancing both convenience and efficiency. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0030] like Figure 1-7 As shown, the present invention provides a constant pressure carbon brush spring pressure detection device for motor rotor, including a mounting plate base 1, a control surface 2, and a movable testing mechanism 3. The top of the mounting plate base 1 is provided with the control surface 2, and multiple movable testing mechanisms 3 are installed on the top of the control surface 2. Each of the multiple movable testing mechanisms 3 is externally connected to a movable extension mechanism 4. A transmission mechanism 5 is provided on the external of the top of the control surface 2. A detection mechanism 6 is installed inside each of the multiple movable testing mechanisms 3. A limit fixing mechanism 7 is provided on the top of each of the multiple movable testing mechanisms 3. A measuring mechanism 8 is provided inside the limit fixing mechanism 7.

[0031] The measuring mechanism 8 includes a storage plate base 801, a sliding plate 802, a measuring scale 803, a clamping plate 804, a third rotating seat 805, a tension spring 806, and a limiting seat 807. The storage plate base 801 is installed on the outer side wall of the top end of the limiting and fixing mechanism 7. The sliding plate 802 is inserted inside the storage plate base 801. The measuring scale 803 is formed on the outer side wall of the top end of the sliding plate 802. The clamping plate 804 is hinged to the outer side of the top end of the sliding plate 802. The third rotating seat 805 is fixedly installed on one side of the outer wall of the clamping plate 804. The tension spring 806 is inserted into the third rotating seat 807. The outer side of the rotating seat 805, the limiting seat 807 is fixedly connected to the outer top of the sliding plate 802, the sliding plate 802 is slidably connected inside the storage plate seat 801, the tension spring 806 is rotatably connected to the third rotating seat 805, the tension spring 806 is movably rotatably connected to the limiting seat 807, the measuring scale 803 is evenly opened on the outer side wall of the top of the sliding plate 802, the clamping plate 804 is elastically telescopically connected to the tension spring 806, the clamping plate 804 is rotatably connected to the top of the sliding plate 802, and the outer surface of the top of the storage plate seat 801 is a smooth stainless steel plate.

[0032] The activity testing mechanism 3 includes a movable slide 301, a contact connecting plate 302, a sliding rod 303, a first limiting plate 304, a first rotating seat 305, and a connecting movable seat 306. The movable slide 301 is located outside the top of the control panel 2. The contact connecting plate 302 is located at the top of the control panel 2. The sliding rod 303 is rotatably connected to the top of the contact connecting plate 302. The first limiting plate 304 is fixedly connected to the outer wall of the contact connecting plate 302. The first rotating seat 305 is inserted outside the bottom end of the first limiting plate 304. The connecting movable seat 306 is fixedly connected to the outer wall of the top of the control panel 2. The sliding rod 303 is inserted through the interior of the movable slide 301. The movable slide 301 is internally slidably connected. The first limiting plate 304 is rotatably connected to the top of the control panel 2 via the first rotating seat 305. The sliding rod 303 rotates around the first rotating seat 305 in the inner circumference of the movable slide 301. When the first limiting plate 304 rotates around the first rotating seat 305, the sliding rod 303 performs a sliding rotation operation inside the movable slide 301. At this time, the detection mechanism 6 detects the abutting pressure of the carbon brush spring 706, causing the carbon brush spring 706 to undergo elastic deformation, thereby controlling the sliding plate 802 to slide inside the storage plate seat 801, so that the deformation of the carbon brush spring 706 during elastic deformation can be conveniently monitored.

[0033] like Figure 2As shown, the movable extension mechanism 4 includes a second rotating seat 401, a rotating shaft 402, and a connecting extension rod 403. The second rotating seat 401 is fixedly connected to the outer wall of the abutting connecting plate 302. The rotating shaft 402 is inserted inside the second rotating seat 401, and the connecting extension rod 403 is connected to the outer surface of the rotating shaft 402. One side wall of the connecting extension rod 403 is fixedly connected to the outside of the transmission mechanism 5. The rotating shaft 402 is rotatably connected inside the second rotating seat 401. The transmission mechanism 5 includes a movable motor 501, a movable rotating gear 502, and multiple connecting gears 503. The movable motor 501 is located above the control panel 2. The outer wall of the output end of the movable motor 501 is fixedly connected to the movable rotating gear 502. Multiple connecting gears 503 are externally engaged with the 2, and multiple connecting rack plates 504 are externally engaged with the multiple connecting gears 503. The connecting gears 503 are evenly arranged on the outer side wall of the movable rotating gear 502. The connecting rack plate 504 is rotatably connected to the connecting gear 503. A connecting top extension rod 403 is fixedly connected to one side of the outer wall of the connecting rack plate 504. After the movable motor 501 is working, it causes the movable rotating gear 502 to rotate. At this time, it drives the connecting gear 503 to rotate, and causes the connecting rack plate 504 to extend and retract. Thus, after the connecting top extension rod 403 extends and retracts, it can extend and retract the rotating shaft 402, thereby driving the first limit plate 304 to extend and retract, and perform pressure testing on the carbon brush spring 706.

[0034] like Figure 5 and Figure 7As shown, the detection mechanism 6 includes an abutment plate 601, a spring guide rod 602, and a connecting guide rod 603. The abutment plate 601 is disposed inside the first limiting plate 304. The spring guide rod 602 is fixedly installed on one outer wall of the abutment plate 601, and the connecting guide rod 603 is fixedly connected to one outer wall of the abutment plate 601. A mounting base 604 is fixedly connected to one side wall of the spring guide rod 602. A pressure sensor 605 is installed on the outside of the mounting base 604. One side of the connecting guide rod 603 is inserted into the pressure sensor 605. The pressure sensor 605 is connected to the abutment plate 601 through the connecting guide rod 603 and the spring guide rod 602. Two spring guide rods 602 are arranged on the upper and lower outer walls of the mounting base 604. The limiting and fixing mechanism 7 includes a placement plate 701, a second limiting plate 702, and a bolt adjusting seat 703. The placement plate 701 is fixedly connected to the top of the connecting movable seat 306. A second limiting plate 702 is provided at the top of the plate 701. A bolt adjusting seat 703 is inserted into the outside of the second limiting plate 702. An abutment seat 704 is fixedly connected to one side wall of the bolt adjusting seat 703. A hanging rod 705 is welded to the top of the second limiting plate 702. A carbon brush spring 706 is sleeved on the outside of the second limiting plate 702. The bolt adjusting seat 703 is threadedly connected to the second limiting plate 702. The hanging rod 705 is sleeved on the outside of the top of the carbon brush spring 706. The connecting end of the carbon brush spring 706 abuts against the outer side wall of the abutment plate 601. After the abutment plate 601 abuts against the connecting end of the carbon brush spring 706, it can perform pressure control testing on the carbon brush spring 706. By rotating and limiting the bolt adjusting seat 703, the carbon brush spring 706 can be fixed after being inserted into the second limiting plate 702. The pressure sensor 605 is model VPMC-A2-P-100.

[0035] Working principle of this invention:

[0036] S1. When performing a pressure test on the carbon brush spring 706, the operator first inserts the carbon brush spring 706 outside the second limiting plate 702, and then screws and rotates the bolt adjusting seat 703 to limit and fix the carbon brush spring 706 outside the second limiting plate 702. Subsequently, after the movable motor 501 operates, it drives the movable rotating gear 502 to rotate, which in turn controls the four connecting gears 503 to rotate synchronously. At this time, after the connecting rack plate 504 meshes with the connecting gears 503, it controls the four connecting rack plates 504 to extend and retract synchronously, thereby controlling the extension rod 403 to extend the rotating shaft 402. After the rotating shaft 402 is extended, this... When the sliding rod 303 rotates around the first rotating seat 305 inside the moving groove 301, and the first limiting plate 304 rotates around the first rotating seat 305, the sliding rod 303 slides and rotates inside the moving groove 301. Thus, when the connecting end of the carbon brush spring 706 abuts against the abutting plate 601, the pressure sensor 605 can detect the pressure during abutment. After the placement plate 701 is connected to the top of the connecting movable seat 306, the placement plate 701 can rotate. Thus, when the core end of the carbon brush spring 706 is fixed, the output end of the carbon brush spring 706 is subjected to pressure after abutment, and the compressive elastic deformation of the carbon brush spring 706 is detected.

[0037] S2. Furthermore, after the carbon brush spring 706 undergoes elastic deformation, the movement and rotation between the clamping plate 804 and the sliding plate 802, as well as the elastic extension and contraction of the clamping plate 804 and the tension spring 806, can perform abutment and limit treatment on the carbon brush spring 706. Subsequently, when the carbon brush spring 706 unfolds its spring sheet after being compressed, the outermost spring sheet of the carbon brush spring 706 is limited by the clamping plate 804, causing the sliding plate 802 to slide and extend outward inside the storage plate base 801. This allows the movement data of the sliding plate 802 after outward movement to be measured and controlled by the measuring scale 803. This enables the measurement of the deformation value of the elastic displacement of the carbon brush spring 706 after being subjected to pressure, as well as the deformation data, facilitating the judgment that the carbon brush spring 706 is qualified under pressure.
