Description
Technical Field
[0001] The present invention relates to the technical field of generators, and in particular to a precise positioning tool for a fixed shaft and a stator of a generator. Background Art
[0002] Both the rotor and the stator are necessary parts for the motor to drive the shaft to rotate. The stator is fixedly mounted on the housing and is usually wound with a coil. The rotor is installed and fixed on the machine base through a bearing or a sleeve. There are silicon steel plates on the rotor, and the rotor of the DC motor also has a coil. When they are both in working condition, the current will flow into the stator and rotor under the action of the coil. A magnetic field is generated on the silicon steel plate, which drives the rotor to rotate. Both the stator and the rotor are composed of an iron core and a winding. The iron core is made of laminated silicon steel plates. The winding is a thick copper wire, the wire is covered with an insulating material and then coated with epoxy resin. The winding is wound on the iron core according to certain standards and methods. The stator and rotor. The stator is the fixed part of the motor, mainly composed of three parts: stator core, stator winding and base, and its main function is to generate a rotating magnetic field. The rotor is the rotating part of the motor, which consists of a rotating shaft, a rotor core and a rotor winding. There is an excitation winding on the rotor. When the excitation current is applied, the rotor rotates under the action of the prime mover, generating an alternating magnetic field. The three-phase winding of the stator cuts off the magnetic lines of force in turn, which will induce an alternating electromotive force of the same magnitude and an electrical angle of 120°. The stator is equivalent to a wire, and the rotor is an electromagnet. The rotor is energized and then rotated by the prime mover to form a rotating magnetic field. Conversely, the wire (stator) cuts off the rotating magnetic field (rotor), which will cause an induced potential to form in the wire, and then the switch will close the wire to allow current to flow. Strictly speaking, both the stator and the rotor have magnetic fields, the difference is that the rotor generates magnetism through electricity, while the stator generates electricity through magnetism.
[0003] During the installation of the generator's fixed shaft and stator, due to the lack of a guide fixture, operators usually use bolts for alignment when docking the fixed shaft and stator. During the alignment process, it is impossible to ensure that the size range difference between the fixed shaft stop and the stator stop is less than 0.3 mm. At the same time, the threaded holes of the fixed shaft and stator cannot be fully aligned, and bolt jamming often occurs. During the installation of the generator's fixed shaft and stator, it is necessary to ensure that the size range difference between the fixed shaft stop and the stator stop is less than 0.3 mm. During the actual assembly process, due to the lack of precise positioning fixtures, the size needs to be constantly adjusted during the placement process. At the same time, the stop gap changes after the bolt torque is tightened, affecting the installation quality and efficiency of the generator's fixed shaft and stator.
[0004] Therefore, there is an urgent need for precise positioning tooling of the generator fixed shaft and stator to solve the above-mentioned problems. Summary of the invention

[0014] Compared with the prior art, the present invention has the following beneficial effects:
[0015] (1) The precise positioning tooling for the fixed axis and stator of the generator first connects the clamping mechanism to the rear end of the outer shell through the connecting pins and tightens it, and at the same time, the positioning mechanism is correspondingly inserted into the fixed axis clamping socket, and by turning the handle, the gear two and the gear one are driven to mesh and rotate, so that the movable column moves forward along the range clamped by the side plate, and the rear column plate is pushed forward by the connection of the long rod, so that the inner column contacts the clamping column and squeezes it outward, so that the clamping plate is correspondingly squeezed and pressed on the inner wall of the stator clamping socket, and by designing four groups of clamping plates up, down, left and right, and the inner column has the same pushing force on the four groups of clamping plates, the positioning sleeve is accurately aligned with the center of the stator clamping socket and fixed, so that the positioning mechanism is set opposite to the center of the stator clamping socket, so that the positioning mechanism and the stator clamping socket are firstly opposite, thereby improving the accuracy of subsequent connection.
[0016] (2) The precise positioning tooling for the fixed axis and stator of the generator synchronously connects the handles on the three adjustment mechanisms through belts, so that adjusting one of the handles can synchronously adjust all the handles. When the center of the stator bayonet is accurately found, synchronous adjustment can be performed first through the linkage of the belt, and then the handles can be tightened one by one. While ensuring accurate connection, the range adjustment is more convenient and quick.
[0017] (3) The precise positioning tooling for the fixed axis and stator of the generator automatically aligns the left and right directions of the stator mechanism and the fixed axis mechanism during the connection process by docking the positioning mechanism and the stator bayonet, and docking the upper adjustment mechanism and the weight reduction mechanism. The fixed axis mechanism and the weight reduction mechanism are connected by sleeve connection with the lower side of the connecting ring 2 through the seat groove. In this way, the fixed axis mechanism is supported by the seat groove, which reduces the interference of gravity on the alignment during the docking process of the fixed axis mechanism, thereby improving the alignment efficiency of the device.
[0018] (4) The precise positioning tooling for the fixed axis and stator of the generator adjusts the height of the fixed axis mechanism by aligning the fixed axis bayonet on the fixed axis mechanism with the guide rod one by one and adjusting the length of the pull rope through the rope drum, so that the fixed axis bayonet and the guide rod are aligned and sleeved. After the fixed axis bayonet and the guide rod are sleeved one by one, the slide column can be quickly moved to the rear side in an aligned manner through the design of the plate slide groove, so that the fixed axis mechanism can be more quickly roughly delivered and docked with the stator mechanism, thereby improving the docking speed of the device. When the fixed axis bayonet is about to move to the front side of the positioning mechanism, the rope drum and the pull rope can be adjusted here to make it completely aligned and docked with the stator mechanism, thereby enhancing the docking accuracy of the device.
[0019] (5) The precise positioning tooling for the fixed axis and stator of the generator, after the stator mechanism and the fixed axis mechanism are connected, at this time, by pulling the hook rope and connecting the bent hook on the front side of the hook rope to the ring of the rear clamping plate, when the hand is turned in the opposite direction, the backward moving column will not only pull the inner column backward to change the interference state between the clamping plate and the stator clamping mouth, but also pull the entire positioning mechanism backward, so that the positioning mechanism is removed from the inside of the stator clamping mouth and the fixed axis clamping mouth, and the threaded column 2 is embedded in them, so that the device can carry out the connection process of the threaded column 2 with the stator mechanism and the fixed axis mechanism under the escort of the facing structure, so that there is no jamming phenomenon in the connection process, and the quality of the connection is improved.
[0020] (6) The precise positioning tooling for the fixed axis and stator of the generator is designed with an adjustment mechanism and a hook rope, so that when the rear column plate is pulled to make the positioning mechanism lose its engagement with the stator and fixed axis snap-ons, the positioning mechanism can be pulled out from the latter at the same time. The entire pulling out process and the separation process are carried out simultaneously, thereby improving the linkage between the device components and effects.
[0021] (7) The precise positioning tooling for the fixed axis and stator of the generator can quickly and accurately complete the docking of the stator mechanism and the fixed axis mechanism through the docking of the device. At the same time, the structure is always connected to ensure that the dimensional difference between the stator bayonet and the fixed axis bayonet during the assembly process is less than 0.3 mm, thereby improving the accuracy of the device docking.
[0022] (8) The generator fixed axis and stator precise positioning tooling is to connect two sets of threaded columns into the stator bayonet and the fixed axis bayonet, then remove the threaded positioning mechanism and the guide rod, and screw the bearing on the outside to complete the accurate docking of the stator mechanism and the fixed axis mechanism. The assembly design of the device facilitates the docking of the device, and at the same time facilitates the storage and separation of the device, thereby improving the flexibility of the device.

[0043] Working principle:
[0044] Step 1: First, the clamping mechanism 5 is clamped to the rear end of the outer shell 102 through the connecting nail 503 and fastened. At the same time, the correcting mechanism 3 is correspondingly inserted into the fixed axis clamping socket 203, and the handle 407 is rotated to drive the gear 2 406 and the gear 1 404 to mesh and rotate, so that the movable column 408 moves forward along the range clamped by the side plate 402, and the rear column plate 309 is pushed forward through the connection of the long rod 410, so that the inner column 308 contacts the clamping column 303 and It is squeezed outward, so that the clamping plate 304 is correspondingly squeezed and pressed on the inner wall of the stator clamping port 105. Through the design of four groups of clamping plates 304 in the upper, lower, left and right directions, and the inner column 308 exerts the same pushing force on the four groups of clamping plates 304, the positioning sleeve 301 is accurately aligned with the center of the stator clamping port 105 and fixed, so that the positioning mechanism 3 is set opposite the center of the stator clamping port 105, so that the positioning mechanism 3 and the stator clamping port 105 are firstly opposite, thereby improving the accuracy of subsequent connection.
[0045] Step 2: Synchronously connect the handles 407 on the three adjustment mechanisms 4 through the belt 412, so that adjusting one of the handles 407 can synchronously adjust all the handles 407. When the center of the stator bayonet 105 is found, synchronous adjustment can be performed first through the linkage of the belt 412, and then the handles 407 can be tightened one by one in turn, which ensures accurate connection and makes range adjustment more convenient and quick.
[0046] Step 3: By docking the alignment mechanism 3 and the stator bayonet 105, and the upper adjustment mechanism 4 and the weight reduction mechanism 7, the stator mechanism 1 and the axis-fixing mechanism 2 are automatically aligned in the left and right directions during the connection process, and the axis-fixing mechanism 2 is connected to the weight reduction mechanism 7 by sleeve-connecting the lower side of the connecting ring 2 202 through the seat groove 708. In this way, the axis-fixing mechanism 2 is supported by the seat groove 708 to reduce the interference of gravity on the alignment during the docking process, thereby improving the alignment efficiency of the device.
[0047] Step 4: By aligning the fixed axis bayonet 203 on the fixed axis mechanism 2 with the guide rod 604 one by one, and adjusting the extended length of the pull rope 706 through the rope drum 705, the height of the fixed axis mechanism 2 is adjusted, so that the fixed axis bayonet 203 and the guide rod 604 are aligned and sleeved. After the fixed axis bayonet 203 and the guide rod 604 are sleeved one by one, the slide column 704 can be quickly moved to the rear side in an aligned manner through the design of the plate slide groove 703, so that the fixed axis mechanism 2 can be more quickly roughly delivered and docked with the stator mechanism 1, thereby improving the docking speed of the device. When the fixed axis bayonet 203 is about to move to the front side of the positioning mechanism 3, the rope drum 705 and the pull rope 706 can be adjusted here to make it completely aligned and docked with the stator mechanism 1, thereby enhancing the accuracy of the device docking.
[0048] Step 5: After the stator mechanism 1 and the fixed axis mechanism 2 are connected, the hook rope 411 is pulled and the hook on the front side of the hook rope 411 is connected to the ring of the rear clamping plate 302. When the handle 407 is rotated in the opposite direction, the rearward moving column 408 will not only pull the inner column 308 backward to change the interference state between the clamping plate 304 and the stator clamping port 105, but also pull the entire positioning mechanism 3 backward, so that the positioning mechanism 3 is removed from the inside of the stator clamping port 105 and the fixed axis clamping port 203 and the threaded column 2 601 is embedded therein, so that the device can carry out the connection process of the threaded column 2 601 with the stator mechanism 1 and the fixed axis mechanism 2 under the escort of the facing structure, so that there is no jamming in the connection process, thereby improving the quality of the connection.
[0049] Step 6: Through the design of the adjustment mechanism 4 and the hook rope 411, the positioning mechanism 3 can be pulled out from the stator snap-in 105 and the fixed axis snap-in 203 while the rear column plate 309 is pulled to make the positioning mechanism 3 lose its engagement therewith. The entire pulling out process and the separation process are carried out synchronously, thereby improving the linkage between the device components and effects.
[0050] Step 7: By docking the device, the stator mechanism 1 and the fixed axis mechanism 2 are quickly and accurately docked. At the same time, the structure is always connected to ensure that the dimensional extreme difference between the stator bayonet 105 and the fixed axis bayonet 203 during the assembly process is less than 0.3 mm, thereby improving the accuracy of the device docking.
[0051] Step 8: After inserting the threaded column 601 into the stator bayonet 105 and the fixed axis bayonet 203, the threaded disassembly of the positioning mechanism 3 and the guide rod 604, and the bearing is screwed on the outside to complete the accurate docking of the stator mechanism 1 and the fixed axis mechanism 2. The assembly design of the device facilitates the docking of the device, and at the same time facilitates the storage and separation of the device, thereby improving the flexibility of the device.
