Description

Technical Field

[0001] This invention relates to the field of windshield wiper assembly technology for high-speed trains, specifically to a device for assembling sensors inside the windshield wiper motor of a high-speed train. Background Technology

[0002] The position sensor inside the windshield wiper motor of the high-speed train has a fully threaded cylindrical structure. The axial distance between its probe cross-section and the sensor mounting plate is a key parameter for Hall signal sensing, directly determining the wiper position detection accuracy, zero-point return reliability, and operational stability. The sensor is fixed to the mounting plate by spring washers on both sides and double nuts. The design intention was to retain the axial adjustment function of the mounting plate to accommodate the machining tolerances of parts and the requirements for wiper zero-point calibration.

[0003] Existing manual assembly methods have significant drawbacks. When manually adjusting the spacing and tightening the nuts, it's difficult to ensure symmetrical deformation of the spring washers on both sides and uniform tightening force. This leads to axial movement of the mounting plate and makes it impossible to guarantee consistent spacing between the sensor probe cross-section and the mounting plate for each device. Spacing deviations can cause weak Hall signals, magnetic field saturation, and detection failures, resulting in wipers not returning to their original position, vibration, fault alarms, and even damage to the sensor probe. This fails to meet the high-speed, safe, and stable operation requirements of high-speed trains. Currently, there is a lack of dedicated devices that can achieve precise automatic spacing adjustment and ensure assembly consistency. Therefore, we propose a device for assembling sensors inside the wiper motor of high-speed trains to solve the aforementioned problems. Summary of the Invention

[0019] like Figure 1-8 As shown: A device for assembling sensors inside the windshield wiper motor of a high-speed train includes a base plate 101. Two sets of side plates 102 are set on the outer sides of the base plate 101. A T-shaped rod 103 is slidably mounted on the upper limit of the side plate 102. The T-shaped rod 103 is fixedly connected to the base plate 101, and a first spring 104 is sleeved on the surface of the T-shaped rod 103. The two ends of the first spring 104 are fixedly connected to the T-shaped rod 103 and the side plate 102 respectively. Sleeve 107 is fixed to one side of side plate 102, and one end penetrates through the side of base plate 101 and extends into base plate 101; The screwing assembly 2 is installed at the end of the sleeve 107 and is used to tighten the double nuts for sensor assembly. The screwing assembly 2 includes a support plate 202 fixed to the end of the sleeve 107. A first motor 203 is fixedly installed on one side of the support plate 202. A worm gear 201 is fixedly installed at the output end of the first motor 203. A nut collet 205 is rotatably installed at the end of the sleeve 107 through a bearing. A worm wheel 204 that meshes with the worm gear 201 is fixed on the surface of the nut collet 205. Locking component 3 is located at the center of the base plate 101 and is used to fix the position of the limit sensor mounting plate. Locking component 3 includes a card holder 301 fixed on one side of the base plate 101. The upper surface of the card holder 301 is provided with a insertion groove. Ball head rods 302 arranged symmetrically slide in the card holder 301. A second spring 303 is fixed between the ball head rods 302 and the card holder 301. The end of the ball head rod 302 is designed with a ball head structure. The ball head of the ball head rod 302 is located in the insertion groove. The insertion groove of the card holder 301 is provided with a matching adjustment plate 304. One end of the adjustment plate 304 is rotatably connected to an adjustment locking rod 305 through a bearing. The adjustment locking rod 305 is threadedly connected to the card holder 301 through a threaded hole. The shifting clamping assembly 4 is mounted on the base plate 101 and is used to clamp and lock the sensor. The shifting clamping assembly 4 includes a connecting plate 401 mounted on one side of the base plate 101. An electric push rod 412 for driving the connecting plate 401 to move is fixedly mounted on the top of the connecting plate 401 by a U-shaped frame. A second motor 402 is fixedly mounted on one side of the connecting plate 401. A lead screw 404 is fixedly mounted on the output end of the second motor 402. A movable seat 403 is limited and slidably mounted on one side of the connecting plate 401. The movable seat 403 and the lead screw 404 are threadedly connected. Two sets of parallel second support rods 406 are hinged to both sides of the movable seat 403. A first support rod 405 is hinged to one side of the connecting plate 401 near the position of the second support rods 406 by a hinge shaft. One end of the first support rod 405 is hinged to one of the sets of second support rods 406. It also includes symmetrically arranged third support rods 407. The ends of the two sets of second support rods 406 are connected to the third support rods 407 via hinge shafts. Clamping plates 408 are fixedly installed on the side of the two sets of third support rods 407 that are close to each other. The side of the two sets of clamping plates 408 that are close to each other has an arc-shaped groove or a V-shaped groove, and a silicone pad is provided in the groove. The U-shaped frame has a strip groove, and a sleeve 410 is slidably limited in the strip groove. A push rod 409 slides in the sleeve 410. The bottom end of the push rod 409 is fixedly connected to the connecting plate 401. The top of the U-shaped frame has symmetrically arranged rollers 411 that rotate via a pivot. The top of the U-shaped frame has symmetrically arranged arc plates 413. A plate is fixed to one side of the sleeve 410, and a pin 414 slides through a circular hole on the plate. A third spring 415 is sleeved on the surface of the pin 414. The two ends of the third spring 415 are fixedly connected to the pin 414 and the plate, respectively. A through circular hole is opened on one side of the sleeve 410. A first electromagnet 416 is fixed to one end of the pin 414, and a second electromagnet 417 is fixedly installed on one side of the top rod 409.

[0020] The second electromagnet 417 and the first electromagnet 416 have opposite magnetic poles. In the initial state of the third spring 415, the first electromagnet 416 and the second electromagnet 417 are not in contact. The sleeve 107 has a first laser sensor 108 fixed inside, and the side plate 102 has a second laser sensor 109 fixedly installed at the bottom by a mounting block. The first laser sensor 108 and the second laser sensor 109 are on the same projection surface. The base plate 101 has two sides hinged with stop bars 105 via hinge shafts, and the upper surface of the side plate 102 is fixed with a socket 106. A slot adapted to the stop bar 105 is provided on one side of the socket 106.

[0021] In this implementation plan: the sensor assembly device inside the windshield wiper motor of the EMU train is used by the operator first vertically inserting the fully threaded cylindrical sensor into the central mounting hole of the sensor mounting plate, ensuring the sensor penetrates the mounting plate and remains axially centered. Then, spring washers and double locking nuts are sequentially fitted onto the left and right ends of the sensor protruding from the mounting plate, completing the pre-assembly of the sensor and mounting plate. The pre-assembled workpiece is then placed as a whole, the sensor mounting plate is aligned downwards and inserted into the insertion slot on the upper surface of the locking assembly 3's retainer 301, completing the initial positioning and loading of the workpiece. After the sensor mounting plate is inserted into the insertion slot of the bracket 301, the two ball-head rods 302 symmetrically arranged inside the bracket 301 extend towards the center of the insertion slot under the elastic thrust of the second spring 303. The ball ends automatically engage with the preset positioning mounting holes on the mounting plate, achieving rigid axial and circumferential bidirectional positioning of the mounting plate and completely avoiding problems such as shaking, offset, or movement of the mounting plate during assembly. For sensor mounting plates of different thicknesses, the operator can rotate and adjust the locking rod 305, using threaded transmission to drive the adjusting plate 304 to move axially inside the bracket 301, changing the effective accommodating thickness of the insertion slot. This allows the device to adapt to mounting plates of different thicknesses for positioning and insertion, improving versatility. When the second motor 402 in the shifting clamping assembly 4 is activated, it rotates in the forward direction. The motor output shaft drives the lead screw 404 to rotate, which, under the limiting and guiding action, causes the moving seat 403 to slide smoothly along the set direction. When the moving seat 403 moves, it pushes the second support rod 406 hinged to it. The second support rod 406, in conjunction with the first support rod 405 and the third support rod 407, forms a stable linkage extension and retraction action, pushing the two sets of symmetrically arranged clamping plates 408 to close synchronously towards the center of the sensor. The clamping plates 408 have arc-shaped grooves or V-shaped grooves on their inner sides and are equipped with silicone pads to flexibly grip the end of the sensor, achieving rigid clamping without damage or slippage, fixing the sensor's posture, and preventing the sensor from rotating or shifting when the nut is tightened subsequently. While keeping the sensor clamped, the operator pulls the side plates 102 on both sides of the base plate 101 outwards, so that the socket 106 fixed on the upper surface of the side plate 102 is completely disengaged from the stop bar 105 connected to the side of the base plate 101 via the hinge shaft, thus releasing the stop bar 105 from limiting and blocking the side plate 102. At this time, under the action of the tension and restoring force, the first spring 104 pulls the T-shaped rod 103, causing the side plate 102 to slide smoothly towards the base plate 101, thereby causing the sleeve 107 fixed inside the side plate 102 to move synchronously towards the end of the sensor, until the nut 205 at the end of the sleeve 107 is completely engaged with the locking nut on the unclamped end of the sensor, and at the same time, the sensor rod extends into the sleeve 107 to avoid structural interference. After sleeve 107 is in place, the first laser sensor 108 and the second laser sensor 109 are activated simultaneously: the first laser sensor 108 is fixed inside sleeve 107, and the laser beam is projected vertically onto the sensor probe end face; the second laser sensor 109 is fixed on the mounting block at the bottom of side plate 102, and the laser beam is projected vertically onto the sensor mounting plate surface. Both sets of laser sensors detect distance signals in real time within the same projection surface, accurately obtaining the axial distance between the sensor probe end face and the mounting plate, and feeding it back to the control system. The tightening assembly 2 is activated, and the first motor 203 drives the worm gear 201 to rotate. The worm gear 201 meshes with the worm wheel 204, driving the nut collet 205 to rotate at a uniform speed, tightening the locking nut and pushing the sensor to move slightly axially. When the laser detection system measures the distance to reach the preset standard value, the control system immediately stops the first motor 203, and the tightening assembly 2 stops operating, completing the single-sided nut tightening and precise axial distance calibration. After the nut on one side is tightened, the second motor 402 is controlled to rotate in reverse, driving the clamping plate 408 to open synchronously and release the clamp on the sensor end. Then, the electric push rod 412 is activated to retract, pulling the sleeve 410 inside the U-shaped frame to slide along the groove. The sleeve 410 drives the top rod 409 and the top roller 411 to move horizontally synchronously. The roller 411 rolls along the surface of the arc plate 413 fixed at the top of the U-shaped frame, lifting the top rod 409 and the connecting plate 401 below upwards as a whole, so that the shifting clamping assembly 4 is raised as a whole and passes over the sensor mounting plate, and moves smoothly to the other end of the sensor. After it is in place, the first electromagnet 416 and the second electromagnet 417 are energized synchronously, generating opposite magnetic pole attraction force, pulling the pin 414 to overcome the elastic force of the third spring 415 and extend it into the positioning hole, rigidly locking the position of the connecting plate 401 to prevent displacement during secondary clamping. After the clamping assembly is repositioned and locked, the second motor 402 is restarted to rotate forward, driving the clamping plate 408 to close again, gripping the other end of the sensor and maintaining the sensor's stable posture. The corresponding screwing assembly 2 at the other end of the sensor is then activated, tightening the locking nut according to the preset torque and speed, ensuring that the spring washers on both sides of the sensor have completely symmetrical deformation and uniform locking force. After the nut is tightened, all actuators such as motors, electromagnets, and push rods are reset sequentially, and the stop rod 105 is re-engaged into the socket 106, restoring the side plate 102 to its limit position. The operator then removes the assembled sensor and mounting plate assembly, completing the entire automated assembly process. This solution effectively solves the problems of low precision, poor consistency, and uneven locking force in the manual assembly of sensors inside the wiper motor of high-speed trains. It has significant technical advantages. By using the first laser sensor 108 and the second laser sensor 109 to achieve dual-point real-time ranging, it can accurately control the axial distance between the sensor probe end face and the mounting plate, ensuring the stability and reliability of the Hall signal, avoiding weak signal, magnetic field saturation and detection failure, and greatly improving the wiper position detection accuracy and zero-point return stability. The dual nuts are tightened symmetrically in segments using the screw-tightening assembly 2, and stably clamped using the shifting clamping assembly 4. This ensures uniform deformation of the spring washers on both sides and consistent locking force, fundamentally preventing axial movement of the mounting plate and avoiding wiper malfunctions and sensor damage. The locking assembly 3 can adapt to mounting plates of different thicknesses by adjusting the locking rod 305 and the adjusting plate 304, offering strong versatility. The device automates the entire process, from material loading and limiting to automatic clamping, spacing calibration, nut tightening, and repositioning and relocking, reducing manual labor intensity and operational errors, and improving assembly efficiency and batch consistency. The overall structure is reliable in positioning, operates smoothly, and clamps without damage, meeting the high-speed, safe, and stable assembly requirements of high-speed trains, demonstrating outstanding practicality and durability.
