Description

Technical Field

[0001] The utility model relates to the technical field of generator production, in particular to a shaping device for cooling a generator end plate. Background Art

[0002] A generator installed in a wind turbine generally includes a stator and a rotor rotating relative to the stator. The stator generally includes a frame body extending longitudinally along a longitudinal axis, and includes a stator yoke and a plurality of teeth. The plurality of teeth protrude from the stator yoke to corresponding radial ends of the teeth according to a radial direction. Each tooth also extends longitudinally between a first longitudinal end of the tooth and a second longitudinal end of the tooth. End plates are generally arranged at the longitudinal ends of the teeth, both at the drive end and the non-drive end. Such end plates installed inside the generator are generally made of plastic and are made by solidifying the plastic in a mold.

[0003] The generator end plate has a high temperature when it is just formed, and it needs to be cooled to room temperature before it can be processed subsequently. During the cooling process, the generator end plate will undergo irreversible deformation due to thermal expansion and contraction, resulting in a decrease in the quality of the generator end plate. To avoid deformation of the generator end plate during the cooling process, it is necessary to shape the generator end plate while it is cooling. When using the existing shaping device, workers are likely to touch the generator end plate. To avoid being burned by the high-temperature generator end plate, workers need to wear protective gloves. However, wearing gloves will reduce the flexibility of the hands, resulting in reduced work efficiency. In view of this, we propose a shaping device for cooling the generator end plate. Utility Model Content

[0004] The purpose of the present utility model is to provide a shaping device for cooling a generator end plate, so as to solve the problems raised in the above background technology.

[0005] To achieve the above-mentioned objectives, one of the objectives of the present invention is to provide a shaping device for cooling an end plate of a generator, comprising a bottom plate, a rectangular array on the top of the bottom plate, and four baffles hingedly connected in a rectangular array on the upper surface of the bottom plate. The hinge point between the baffle and the bottom plate is close to the edge of the bottom plate, and the baffle is provided with an oblique groove at the other end away from the hinge of the bottom plate, and the upper side of the bottom plate is symmetrically fixedly connected with two pads near the middle. The pads are arranged at a position between the two embedded grooves. When the baffle rotates to a horizontal state and the other end of the baffle is close to the middle position of the bottom plate, the baffle is arranged on the upper side of the embedded groove, and the other end of the baffle contacts the upper surface of the pad. A vertical plate is fixedly connected at the center of the upper surface of the pad, and pressure plates and displacement mechanisms are symmetrically provided on both sides of the vertical plate. The displacement mechanism is used to drive the corresponding pressure plates close to or away from the vertical plate. When the displacement mechanism drives the pressure plate away from the vertical plate and the other end of the baffle contacts the upper surface of the pad, one end of the pressure plate contacts the oblique groove.

[0006] As a further improvement of the present technical solution, a plurality of cooling cavities are provided inside the base plate, and the plurality of cooling cavities are interconnected through hoses. The interior of the cooling cavities is filled with liquid for cooling the generator end plate placed in the embedded groove.

[0007] As a further improvement of the present technical solution, the displacement mechanism includes two screw rods rotatably arranged on one side of the vertical plate, and two side plates are symmetrically fixedly connected to both sides of the pressure plate, and the two side plates are respectively threadedly connected to the two screw rods.

[0008] As a further improvement of this technical solution, a worm gear is coaxially fixedly connected to one end of the screw rod close to the vertical plate, a worm gear is rotatably provided on the upper surface of the pad, and the two worm gears located on one side of the vertical plate are both engaged with the worm gear.

[0009] As a further improvement of the present technical solution, one end of the worm extends to the outside of the pad and is coaxially fixedly connected to a driven gear. A driving gear is rotatably provided on the upper surface of the base plate. The driving gear is located on the side where the two driven gears are away from each other, and the driving gears are respectively engaged with the driven gears. A crank is coaxially fixedly connected to the rotating shaft of the driving gear.

[0010] Compared with the prior art, the present invention has the following beneficial effects:

[0011] The shaping device for cooling the generator end plate places the generator end plate to be cooled inside one of the embedded grooves, rotates the corresponding baffle to a horizontal state, and then locks the position of the baffle. This allows the baffle to cooperate with the embedded groove to prevent the generator end plate from deforming due to expansion and contraction, thereby ensuring the quality of the generator end plate after cooling. At the same time, when locking the baffle position, the worker's hands will not come into contact with the generator end plate, preventing the worker from being scalded by the high-temperature generator end plate, thereby ensuring the worker's safety.

[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] Example 1

[0024] See also Figure 1-Figure 2 As shown, one of the purposes of this embodiment is to provide a shaping device for cooling a generator end plate, comprising a base plate 1, wherein a rectangular array on the top of the base plate 1 is provided with four embedded grooves 11, and a plurality of cooling cavities are provided inside the base plate 1. The plurality of cooling cavities are interconnected by hoses 12, and the interior of the cooling cavities is filled with liquid for cooling the generator end plate placed in the embedded grooves 11. The two hoses 12 connected to the two outermost cooling cavities are respectively connected to an inlet pipe and an outlet pipe. The inlet pipe injects liquid into the interior of the plurality of cooling cavities, and the liquid in the cooling cavities is then discharged through the outlet pipe, so that the liquid continuously flows inside the plurality of cooling cavities. The base plate 1 is made of steel with good thermal conductivity. The temperature of the base plate 1 as a whole is maintained below room temperature through heat exchange between the liquid and the cooling cavities. When the generator end plate with a higher temperature is placed inside the embedded grooves 11, and the lower surface and four side surfaces of the generator end plate are in contact with the inner wall of the embedded grooves 11, the heat exchange between the base plate 1 and the generator end plate causes the generator end plate to cool down rapidly, thereby facilitating subsequent processing of the generator end plate.

[0025] When the temperature inside the embedded groove 11 drops, the generator end plate will deform due to thermal expansion and contraction, resulting in a decrease in the quality of the generator end plate. To solve this problem, four baffles 2 are hinged in a rectangular array on the upper surface of the base plate 1. The hinge between the baffles 2 and the base plate 1 is close to the edge of the base plate 1. Two pads 3 are symmetrically fixedly connected near the middle of the upper side of the base plate 1. The pads 3 are set between the two embedded grooves 11. When the lower surface of the generator end plate contacts the bottom surface inside the embedded groove 11, the top position of the generator end plate On the outside of the embedded groove 11, the baffle 2 is rotated to a horizontal state, and the other end of the baffle 2 is close to the middle position of the base plate 1. In this state, the baffle 2 is set on the upper side of the embedded groove 11, and the other end of the baffle 2 is in contact with the upper surface of the pad 3. When the generator end plate is placed in the embedded groove 11, the middle section of the baffle 2 is in close contact with the upper surface of the generator end plate. At this time, the position of the baffle 2 is fixed to prevent the generator end plate from deforming due to expansion and contraction, thereby ensuring the quality of the generator end plate after cooling.

[0026] In order to fix the baffle 2 in a horizontal state and prevent the worker from contacting the generator end plate when fixing the baffle 2, and to prevent the high temperature generator end plate from scalding the worker's hands, please refer to Figure 2 , an inclined groove 21 is provided at the other end of the baffle 2 away from the hinged end of the base plate 1, and a vertical plate 31 is fixedly connected at the center of the upper surface of the pad 3. Pressure plates 4 and displacement mechanisms 5 are symmetrically provided on both sides of the vertical plate 31. The displacement mechanism 5 is used to drive the corresponding pressure plates 4 to move closer to or away from the vertical plate 31. When the baffle 2 rotates to a horizontal state and the other end of the baffle 2 contacts the upper surface of the pad 3, the worker drives the pressure plate 4 away from the vertical plate 31 through the displacement mechanism 5, so that one end of the pressure plate 4 contacts the inclined groove 21, so that the pressure plate 4 can prevent the baffle 2 in the horizontal state from rotating upward, thereby stabilizing the baffle 2 in the horizontal state, so that the baffle 2 prevents the generator end plate from deforming due to expansion and contraction.

[0027] The structure of the displacement mechanism 5 is detailed below. Figure 3 and Figure 4The two worm wheels 53 on one side of the vertical plate 31 are meshed with the worm 54, and the worm 54 is rotated. The engagement transmission of the worm 54 and the worm wheel 53 causes the two worm wheels 53 to respectively drive the two screw rods 52 to rotate. Through the threaded connection between the screw rod 52 and the side plate 41, the two side plates 41 drive the pressure plate 4 along the axis direction of the screw rod 52 to approach the baffle 2. By making the pressure plate 4 contact the inclined groove 21 on the baffle 2, the baffle 2 can be fixed in a horizontal state, so that the baffle 2 prevents the generator end plate from deforming due to expansion and contraction.

[0028] At the same time, when the worker holds the crank 57 and rotates the driving gear 56, the crank 57 serves as a labor-saving lever, enabling the worker to rotate the worm 54 more labor-saving.

[0029] When using this device, the worker places the newly formed generator end plate with a higher temperature inside one of the embedded grooves 11, and then rotates the baffle 2 corresponding to the embedded groove 11 to a horizontal state, and makes the other end of the baffle 2 contact the upper surface of the pad 3, so that the middle section of the baffle 2 can contact the upper surface of the generator end plate. The worker then rotates the corresponding crank 57 to move the pressure plate 4 corresponding to the baffle 2 horizontally away from the vertical plate 31 until one end of the pressure plate 4 contacts the inclined groove 21 on the baffle 2, fixing the baffle 2 in a horizontal state, so that the baffle 2 in a horizontal state prevents the generator end plate from deforming during the cooling process. The worker only needs to rotate the crank 57 away from the generator end plate to fix the position of the baffle 2, thereby greatly reducing the possibility of the worker's hands contacting the generator end plate and preventing the worker from being scalded by the high-temperature generator end plate.
