Description

Technical Field

[0001] This utility model relates to the field of wind power generation, and in particular to a gear processing fixture for wind turbine generators. Background Technology

[0002] A wind turbine generator set is a system that converts the kinetic energy of wind into electrical energy. It consists of components such as a wind turbine, generator, deflector, tower, speed limiting safety mechanism, and energy storage device. Wind turbine generator sets generally use gearboxes or gear speed-up devices to increase the generator speed. As an important driving component, the transmission gear must be processed within strict dimensional requirements. Therefore, when processing such gears, corresponding processing fixtures are usually required to ensure processing stability. As shown in the Chinese Patent Network, a processing fixture for transmission gears of wind turbine generators (publication announcement number CN219169803U) is used. When processing and positioning the gear, this type of fixture clamps the gear body teeth with a locking block. Pressing the locking block can cause another connecting ring and locking block to pop up, clamping two sets of gear bodies of different sizes. This allows for all-round clamping of the gear, preventing gear rotational deviation when processing from the side, thus ensuring that the processed gear has almost no dimensional deviation.

[0003] However, the gear processing fixtures disclosed in the aforementioned patents and those currently used in the market still have some shortcomings: Existing methods using elastic conversion components to achieve staggered ejection of two sets of clamping blocks for locking and limiting different gear teeth, while offering relatively flexible control, have limited adaptability to gear clamping and positioning. They can only be used for clamping and fixing a limited number of gear models, and their flexible control and adaptability are not efficient enough. Therefore, those skilled in the art provide a gear processing fixture for wind turbines to solve the problems mentioned in the background section. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this utility model provides a gear processing fixture for wind turbines, which solves the problem mentioned in the background art that the existing gear processing fixtures for wind turbines are not efficient enough in terms of gear clamping adaptability.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: a gear processing fixture for wind turbine generators, comprising a support base and a positioning rod installed in the middle of the support base;

[0006] The positioning rod includes an integrally connected splined shaft and a positioning screw;

[0007] A gear positioning fixture is fitted on the outer side of the spline shaft.

[0008] The positioning screw is screwed with a compression sleeve along its bolt direction;

[0009] A washer is provided between the compression nut and the gear positioning fixture, and the washer is looped around the positioning rod. The number of washers is not less than one set.

[0010] As a further technical solution of this utility model: the gear positioning fixture includes a spline sleeve that is ringed on the spline shaft. Two sets of adjusting frames are symmetrically arranged on both sides of the sleeve of the spline sleeve. The adjusting frame is slidably connected to a telescopic frame along its support direction. The support of the adjusting frame is provided with an adjusting and braking mechanism for driving the telescopic frame. The top of the support of the telescopic frame is provided with a locking tooth seat.

[0011] As a further technical solution of this utility model: the inside of the bushing of the spline sleeve is provided with a spline groove that is adapted to the spline shaft.

[0012] As a further technical solution of this utility model: the support of the adjustment frame is provided with guide rails on both sides in a symmetrical manner, and the tail end of the support of the telescopic frame is provided with guide slides adapted to the guide rails in a symmetrical manner.

[0013] As a further technical solution of this utility model: the adjusting braking mechanism includes a brake screw arranged along the direction of the adjusting frame support and an adjusting knob installed at one end of the adjusting frame support. The knob shaft of the adjusting knob is provided with a bevel gear A, and one end of the shaft of the brake screw is provided with a bevel gear B that meshes with the bevel gear A. A brake sleeve is sleeved on the outside of the shaft of the brake screw, and a brake shaft sleeve that outerly covers the brake screw is provided on one side of the brake sleeve. The brake shaft sleeve supports the telescopic frame.

[0014] As a further technical solution of this utility model: the inner ring of the washer is larger than the outer ring of the spline shaft, and the outer ring of the washer is the same size as the spline sleeve opening of the gear positioning fixture.

[0015] This utility model provides a gear machining fixture for wind turbines, which has the following advantages compared with the prior art: When the gear of this design is being positioned and machined, after the gear passes through the positioning rod and is placed on the support, the gear positioning fixture is simultaneously passed through the positioning rod and pressed flat on the gear. The locking tooth seat is adjusted and aligned by the extension and retraction drive of the braking mechanism in the gear positioning fixture, so that the locking sleeve is placed on the gear teeth, locking the gear positioning fixture and the gear together. Then, the gear positioning fixture is pressed and positioned by the height of the washer and the thread of the tightening screw sleeve, so as to achieve the limit and fixation of the gear's upper and lower and horizontal positions, ensuring the stability of gear machining. Its adjustment and adaptation are more flexible and versatile, and it can be adapted to clamp and position various types of gears while achieving integrated upper and lower and horizontal locking and positioning of the gear, resulting in better clamping and positioning machining stability.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-5This utility model provides a technical solution for a gear machining fixture for wind turbines: A gear machining fixture for wind turbines includes a support base 1 and a positioning rod 2 installed in the middle of the support base 1. The positioning rod 2 includes a splined shaft 21 and a positioning screw 22 integrally connected. A gear positioning fixture 3 is sleeved on the outer side of the splined shaft 21. The gear positioning fixture 3 includes a splined sleeve 31 that is ringed on the splined shaft 21. The inside of the sleeve of the splined sleeve 31 is provided with a spline groove 32 that is adapted to the splined shaft 21. By utilizing the meshing and matching of the spline groove 32 with the teeth of the splined shaft 21, when the gear positioning fixture 3 is ringed on the splined shaft 21 and meshes and locks with the teeth of the gear body 6, the meshing of the spline groove 32 with the splined shaft 21 can act as a locking component to prevent the gear body 6 from undergoing horizontal skew displacement during machining, and to lock and limit the gear body 6 in the horizontal direction.

[0024] Two sets of adjusting frames 34 are symmetrically arranged on both sides of the bushing of the spline sleeve 31. The adjusting frame 34 is slidably connected to the telescopic frame 35 along its support direction. The two sides of the support of the adjusting frame 34 are symmetrically arranged with guide rails 37. The tail end of the support of the telescopic frame 35 is symmetrically arranged with guide slides 38 that are adapted to the guide rails 37. By using the guide rails 37 and guide slides 38, a horizontal guiding and limiting function is achieved, so that the telescopic frame 35 can be adjusted and aligned along the support direction of the adjusting frame 34.

[0025] The bracket of the adjusting frame 34 is equipped with an adjusting and braking mechanism that drives the telescopic frame 35. The top of the bracket of the telescopic frame 35 is equipped with a locking gear seat 36. The adjusting and braking mechanism includes a brake screw 313 arranged along the direction of the adjusting frame 34 bracket and an adjusting knob 33 installed at one end of the adjusting frame 34 bracket. The knob shaft of the adjusting knob 33 is equipped with a bevel gear A310. One end of the shaft of the brake screw 313 is equipped with a bevel gear B311 that meshes with the bevel gear A310. A brake sleeve 312 is sleeved on the outside of the shaft of the brake screw 313. A brake sleeve is provided on one side of the brake sleeve 312. The brake bushing 39 of rod 313 supports the telescopic frame 35. By turning the adjustment knob 33, the bevel gear A310 is driven to rotate. The meshing transmission of bevel gear A310 and bevel gear B311 drives the brake screw 313 to rotate, driving the combination of brake sleeve 312 and brake bushing 39 to perform horizontal braking. As a driving source, the telescopic frame 35 is pushed to extend and retract along the support direction of the adjustment frame 34 for adjustment and positioning. The distance between the two sets of locking tooth seats 36 is adjusted in opposite directions to keep the two sets of locking tooth seats 36 at a suitable distance and clamp them on the teeth of the gear body 6.

[0026] A clamping sleeve 5 is screwed onto the positioning screw 22 along its bolt direction. A washer 4 is placed between the clamping sleeve 5 and the gear positioning fixture 3 and is looped around the positioning rod 2. There is at least one set of washers 4. The inner ring of the washer 4 is larger than the outer ring of the spline shaft 21, and the outer ring of the washer 4 is the same size as the spline sleeve opening of the gear positioning fixture 3. After the gear positioning fixture 3 is flatly locked onto the gear body 6, the washer 4 is flatly placed on the spline sleeve 31 of the gear positioning fixture 3, and the height of the washer 4 is higher than the height of the spline shaft 21. Then the clamping sleeve 5 is pushed along the thread of the positioning screw 22. The gear positioning fixture 3 is clamped and positioned by the washer 4, so as to clamp and fix the gear positioning fixture 3 in the upper and lower positions.

[0027] The working principle of this utility model is as follows: When clamping and positioning the wind turbine gear, the distance between the two sets of locking tooth seats 36 in the gear positioning fixture 3 is adjusted according to the size and model of the gear body 6 to fit the gear body 6. Then, during the adjustment process, by turning the adjustment knob 33, the combination transmission of bevel gear A310 and bevel gear B311 is driven, which in turn drives the brake screw 313 to rotate, driving the combination of brake sleeve 312 and brake shaft sleeve 39 to perform horizontal braking, pushing the telescopic frame 35 to extend and retract along the support direction of the adjustment frame 34 to adjust the position, and adjusting the distance between the two sets of locking tooth seats 36 in opposite directions so that the two sets of locking tooth seats 36 maintain a suitable distance and are clamped on the teeth of the gear body 6.

[0028] Then, the gear body 6 to be processed is passed through the positioning rod 2 and placed on the support seat 1. At the same time, the gear positioning fixture 3 is guided and installed along the positioning rod 2, so that the spline sleeve 31 of the gear positioning fixture 3 is engaged and locked on the spline shaft 21, and the two sets of locking tooth seats 36 of the gear positioning fixture 3 are locked on the teeth of the gear body 6, forming a horizontal locking positioning.

[0029] After the gear positioning fixture 3 is flat-pressed and locked onto the gear body 6, the washer 4 is passed through the positioning rod 2 and flatly placed on the spline sleeve 31 of the gear positioning fixture 3, and the height of the washer 4 is higher than the height of the spline shaft 21, so that the clamping screw sleeve 5 can clamp and position the gear positioning fixture 3 through the washer 4. Then, the clamping screw sleeve 5 is pushed along the thread of the positioning screw 22, and the gear positioning fixture 3 is clamped and positioned through the washer 4, so as to clamp and fix the gear positioning fixture 3 in the upper and lower positions. Its clamping and positioning state can not only adapt to the clamping and positioning of various types of gears, but also realize the vertical and horizontal integrated locking and positioning of the gear, and the clamping and positioning processing stability is better.

[0030] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model are implemented according to conventional methods in the art, unless otherwise specified or limited.
