Description

Technical Field

[0001] The invention relates to the technical field of tooling and fixtures, and in particular to a tooling and fixture for high-precision gear shaping processing of a wind power gearbox. Background Art

[0002] During the processing of the gears in the wind turbine gearbox, gear shaping is one of the important processing steps. During gear shaping, a tooling fixture is required to provide stable positioning and clamping force to ensure high precision during gear shaping. There are still some problems with the existing tooling fixtures when they are used, such as:

[0003] 1. The patent name disclosed in the prior art with application number "CN202321492193.8" is "a tooling fixture for a gear shaping machine", which includes a fixture seat and a clamping assembly, wherein the clamping assembly includes a cross cavity through the fixture seat, and a first double-threaded rod and a second double-threaded rod respectively installed vertically and crosswise in the cross cavity, and the first double-threaded rod and the second double-threaded rod in the cross cavity are symmetrically and matchedly installed on both sides of the upper ends thereof, and rubber blocks are fixedly installed on the inner ends of the first and second sliders, and the first double-threaded rod and the second double-threaded rod are respectively installed vertically and crosswise in the cross cavity. The first double-threaded rod and the second double-threaded rod installed vertically and crosswise in the cross cavity can respectively drive the first and second sliders symmetrically installed on both sides of the upper end of the fixture seat to open and close, so as to quickly fix and clamp workpieces of different sizes in the center before processing, so as to avoid delaying the processing time due to the adjustment of the four sides of the fixture, and the pressing plate installed in the movable groove of the first and second sliders can bind and press the upper end surface of the workpiece, so as to enhance its fixing effect, and can also adjust the height according to workpieces of different sizes;

[0004] When the above-mentioned fixture is in use, since the areas of the first slider, the second slider, the rubber block and the pressure plate are fixed, when the first slider and the second slider clamp a workpiece with a larger diameter, the contact and clamping area of ​​the first slider and the second slider with the workpiece with a larger diameter will be smaller, resulting in more area of ​​the workpiece with a larger diameter not being clamped, thereby making the stability of the subsequent clamping poor, resulting in the poor clamping effect of the entire fixture on the workpiece with a larger diameter, and then affecting the high precision of the clamping of the entire fixture;

[0005] 2. The patent name disclosed in the prior art with application number "CN202321624506.0" is "A convenient cleaning tool for gear shaping machines". When the gear shaping cutter moves downward, the force plate will be pressed, thereby driving the rod to make the extrusion plate move downward. The driving rod and the force plate are fixed by bolts, and the extended length of the force plate can be freely changed to ensure that the force plate can fully contact the gear shaping cutter. At this time, the extrusion plate pulls the auxiliary tension spring to squeeze the airbag, and the gas inside the airbag is transported to the nozzle through the jet hose. The nozzle sprays airflow to the processing position of the gear and the gear shaping cutter, thereby cleaning the debris in the tooth gap of the gear. By loosening the positioning pin, the angle of the airflow sprayed by the nozzle can be adjusted, thereby ensuring that the airflow can accurately contact the gear gap, while improving the flexibility of the device and further ensuring the cleaning effect;

[0006] Although the fixture mentioned above can spray air through the nozzle to blow it to the processing position of the gear and the gear shaping cutter, thereby cleaning the debris in the tooth gap of the gear, the debris will be blown off and scattered at various positions on the surface of the fixture, which will not only make it inconvenient to collect the debris later, but also make the debris affect the use of the fixture;

[0007] Therefore, we proposed a high-precision wind power gearbox gear shaping tooling fixture to solve the above problems. Summary of the invention

[0031] Compared with the prior art, the beneficial effects of the present invention are as follows: the tooling fixture for high-precision gear shaping processing of wind power gearbox can increase the contact area when clamping the gear blank with a larger diameter through the mutual cooperation of the main clamping plate and the auxiliary clamping plate, thereby clamping a larger area of ​​the workpiece with a larger diameter, thereby improving the stability of the later clamping, improving the clamping effect of the entire tooling fixture on the workpiece with a larger diameter, so that the tooling fixture can ensure the high precision of positioning of the gear blank during the processing process, and the specific contents are as follows:

[0032] (1) When the main clamping plate moves outward to clamp the inner wall of the larger diameter gear blank, the adjusting rod is automatically driven to rotate by pulling the connecting rope, so that the adjusting rod drives the auxiliary clamping plate to rotate outward, so that the auxiliary clamping plate fits the inner wall of the larger diameter gear blank. The main clamping plate and the auxiliary clamping plate cooperate with each other to increase the contact area with the larger diameter gear blank when clamping, so that a larger area of ​​the larger diameter workpiece is clamped, thereby improving the stability of the later clamping and the clamping effect of the entire fixture on the larger diameter workpiece, so that the fixture can ensure the high precision of the positioning of the gear blank during the processing;

[0033] When the main clamping plate moves inward to clamp the outer wall of the larger diameter gear blank, the outer surface of the gear blank applies an outward thrust to the auxiliary clamping plate, so that the auxiliary clamping plate automatically rotates outward to fit the outer wall of the larger diameter gear blank, thereby increasing the contact area when clamping the larger diameter gear blank through the mutual cooperation of the main clamping plate and the auxiliary clamping plate, and also improving the clamping effect of the entire fixture on the larger diameter workpiece;

[0034] The rotation of the second bevel gear can simultaneously drive the four sets of first bevel gears to rotate, and then the four sets of first bevel gears drive the four sets of threaded rods to rotate simultaneously, and then the four sets of main clamping plates move synchronously;

[0035] By using the main clamping plate and the auxiliary clamping plate both of which are arc-shaped structures in coordination, the entire fixture can clamp the inner wall or the outer wall of the gear blank, thereby facilitating the gear shaping process on the outer wall or the inner wall of the gear blank, so that the fixture can meet different usage requirements;

[0036] (2) The inner support plate is used to support the top of the inner guide cover, so that the inner guide cover made of umbrella cloth can be well opened, which is convenient for the inner guide cover to collect the debris generated when the inner wall of the gear blank is processed by the gear shaping process, and the debris is later allowed to fall into the inner collection frame for temporary collection and storage;

[0037] The upper part of the outer air guide cover is supported by the outer supporting plate, and the upper part of the outer air guide cover is tilted and the lower part of the outer air guide cover is vertical by the support of the support assembly, so that the outer air guide cover can guide the debris generated by the gear shaping process on the outer wall of the gear blank to the outer collection frame for collection and temporary storage;

[0038] Furthermore, when the rotary control plate rotates, the automatic control block with inclined sides can automatically push the swing arm and the support assembly to rotate upward and then downward, and then the support assembly can reciprocate up and down to shake the outer air guide cover, thereby allowing the debris on the outer side of the outer air guide cover to be well guided to the outer collection frame for collection and temporary storage.

For details, refer to the attached Figure 1-Figure 8 As shown, a mounting base 1 for mounting a fixture is provided, an outer collection frame 2 is provided above the mounting base 1, and a rotating control plate 3 is provided above the middle of the outer collection frame 2; four groups of main clamping plates 4 are connected above the rotating control plate 3, and two auxiliary clamping plates 5 are symmetrically connected to the outer sides of the main clamping plates 4; a synchronous control assembly for regulating the simultaneous movement of the four groups of main clamping plates 4 is provided inside the upper surface of the rotating control plate 3; an outer support plate 7 is provided below the outer side of the main clamping plates 4, and an inner support plate 6 is provided below the inner side of the main clamping plates 4, and both the inner support plate 6 and the outer support plate 7 are provided in a fan-shaped structure. A motor is provided inside the middle of the outer collection frame 2, and a rotating shaft 301 is provided at the bottom of the rotating control plate 3, and the lower end of the rotating shaft 301 passes through the outer collection frame 2 and is connected to the output end of the motor. The synchronous control assembly includes a vertical rod 11 installed in the middle of the rotating control plate 3, the upper outer key of the vertical rod 11 is connected to the second bevel gear 111, and the lower part of the vertical rod 11 is connected to the motor inside the rotating control plate 3;

[0055] A threaded rod 10 is installed in the internal grooves at equal intervals on the upper surface of the rotating control plate 3, a first bevel gear 101 is installed on the outer side of one end of the threaded rod 10, and the upper part of the first bevel gear 101 is meshed and connected with the second bevel gear 111; a moving block 12 is threadedly connected to the outer side of the threaded rod 10, and a connecting rod 121 with an "L"-shaped structure is installed above the moving block 12, and the end of the connecting rod 121 away from the moving block 12 is connected to the bottom surface of the main clamping plate 4, and the main clamping plate 4 forms a sliding structure with the rotating control plate 3 through the connecting rod 121. The main clamping plate 4 and the auxiliary clamping plate 5 are both arranged in an arc-shaped structure. The two side surfaces of the main clamping plate 4 are grooved with an adjusting rod 15, and the auxiliary clamping plate 5 is installed on the outer side of the middle of the adjusting rod 15. The auxiliary clamping plate 5 forms a rotating structure with the main clamping plate 4 through the adjusting rod 15; the upper outer side of the adjusting rod 15 is sleeved with a first vortex spring 151, and the lower outer side of the adjusting rod 15 is wound with a connecting rope 14. Two sets of guide wheel assemblies 13 are symmetrically installed on the bottom surface of the main clamping plate 4, and the lower end of the connecting rope 14 passes through the guide wheel assembly 13 and is connected to the upper surface of the rotating control plate 3;

[0056] First, the entire fixture is installed in the working area through the mounting base 1. Then, when the inner wall of the larger diameter gear blank needs to be clamped, the larger diameter gear blank is first sleeved on the outer side of the four sets of main clamping plates 4. Then, the motor inside the rotation control plate 3 is started, so that the motor drives the vertical rod 11 to rotate. At this time, the vertical rod 11 drives the second bevel gear 111 on the outside to rotate. Then, the second bevel gear 111 drives the first bevel gear 101 meshed with the surrounding below to rotate. At this time, the first bevel gear 101 drives the internal threaded rod 10 to rotate. Then, when the threaded rod 10 rotates, it drives the moving block 12 connected to the outer thread to move outward. At this time, the moving block 12 drives the connecting rod 121 with an "L" shape structure to move outward. At this time, the connecting rod 121 drives the main clamping plate 4 to move outward. When the outer side surface of the main clamping plate 4 moves to the inner wall of the larger diameter gear blank, When the fitting contact is made, the outer support plate 7 supports the bottom surface of the gear blank. At the same time, the main clamping plate 4 moves outward and drives the guide wheel assembly 13 below to move outward together. At this time, the guide wheel assembly 13 will limit the connection rope 14, and then the connection rope 14 is pulled to drive the adjusting rod 15 to rotate. When the adjusting rod 15 rotates, it drives the first vortex spring 151 to store force. At the same time, when the adjusting rod 15 rotates, it drives the auxiliary clamping plate 5 to rotate outward, so that the outer side surface of the auxiliary clamping plate 5 contacts and clamps the inner side wall of the larger diameter gear blank. Therefore, through the coordinated use of four groups of main clamping plates 4 and auxiliary clamping plates 5, the outer side surfaces of the main clamping plates 4 and the auxiliary clamping plates 5 are all in contact and clamped with the inner side wall of the larger diameter gear blank, thereby increasing the contact area between the tooling fixture and the inner side wall of the larger diameter gear blank, which is convenient for more stable clamping in the later stage and ensures the high precision of positioning of the gear blank during the processing;

[0057] Then, after the jig clamps and fixes the larger diameter gear blank, during the gear shaping process, the motor inside the outer collecting frame 2 drives the rotating shaft 301 to rotate intermittently, and then the rotating shaft 301 drives the rotating control plate 3 to rotate intermittently, and then the rotating control plate 3 drives the gear blank to rotate intermittently, and then the outer wall of the larger diameter gear blank can be gear shaped;

[0058] When it is necessary to clamp the outer wall of the gear blank with a larger diameter, the motor inside the rotating control plate 3 is started, so that the motor drives the vertical rod 11 to rotate. At this time, the vertical rod 11 drives the second bevel gear 111 on the outside to rotate, and then the second bevel gear 111 drives the first bevel gear 101 meshed and connected around the bottom to rotate. At this time, the first bevel gear 101 drives the internal threaded rod 10 to rotate, and then the threaded rod 10 rotates to drive the moving block 12 connected to the outer thread to move outward. At this time, the moving block 12 is stably in the groove on the upper surface of the rotating control plate 3. The moving block 12 drives the connecting rod 121 in the "L" shape to move outward, and the connecting rod 121 drives the main clamping plate 4 to move outward to the farthest distance. At the same time, as shown above, the main clamping plate 4 will drive the guide wheel assembly 13 to move together when it moves outward. At this time, the guide wheel assembly 13 will limit the connection rope 14, and then the connecting rope 14 will drive the adjusting rod 15 to rotate when it is pulled. When the adjusting rod 15 rotates, it drives the first vortex spring 151 to store force. At the same time, when the adjusting rod 15 rotates, it drives the auxiliary clamping plate 5 to rotate outward;

[0059] Then, the gear blank with a larger diameter is placed on the inner side of the four sets of main clamping plates 4, and then the vertical rod 11 is rotated in the opposite direction. Similarly, the main clamping plate 4 is driven to move inward through the connecting rod 121. While the main clamping plate 4 moves inward, the adjusting rod 15 is forced by the first vortex spring 151 to rotate in the opposite direction to reel in the connecting rope 14, thereby causing the adjusting rod 15 to drive the auxiliary clamping plate 5 to rotate in the opposite direction to reset. At the same time, when the inner side wall of the main clamping plate 4 fits with the outer side surface of the gear blank with a larger diameter, the outer side of the gear blank with a larger diameter is The wall will also apply an outward thrust to the auxiliary clamping plate 5, so that the inner wall of the auxiliary clamping plate 5 is always in contact with the outer wall of the larger diameter gear blank. At this time, the inner support plate 6 supports the bottom surface of the gear blank. Therefore, the outer wall of the larger diameter gear blank is stably clamped and fixed through the cooperation of the main clamping plate 4 and the auxiliary clamping plate 5, and then the inner wall of the larger diameter gear blank can be gear-shaped. Therefore, the fixture can meet different clamping requirements and can perform gear shaping operations on the inner wall or the outer wall of the gear blank.

[0060] When clamping a gear blank with a smaller diameter, as shown above, it is only necessary to control the rotation of the vertical rod 11 to drive the four sets of main clamping plates 4 to move outward or inward to perform the clamping operation;

[0061] Embodiment 2: The high-precision wind power gearbox gear shaping processing tooling fixture in this embodiment can collect the debris generated during the gear shaping process to prevent the debris from falling on the tooling fixture and affecting the subsequent use of the tooling fixture. For details, please refer to the attached Figure 1-Figure 4As shown, an inner air deflector 8 is installed below the inner support plate 6; an outer air deflector 9 is installed below the outer support plate 7, an inner collecting frame 81 is installed on the bottom surface of the inner air deflector 8, and the inner collecting frame 81 is installed in the middle of the upper surface of the rotating control plate 3. The inner air deflector 8 is a funnel-shaped structure, and the material of the inner air deflector 8 is an umbrella cloth material. A collection groove 201 with a circular ring structure is opened on the upper surface of the outer collecting frame 2, and the lower part of the outer air deflector 9 is placed in the collection groove 201. The diameter of the collection groove 201 is larger than the diameter of the outer air deflector 9, and the material of the outer air deflector 9 is an umbrella cloth material. A circle of support components 16 are evenly spaced on the outside of the rotating control plate 3 through a mounting mechanism. The support components 16 are arranged in an arc-shaped structure, and the outer side surface of the support components 16 is fitted with the inner side wall of the outer air deflector 9. The mounting mechanism includes a circle of swinging rods 161 mounted at equal intervals on the outside of the rotating control plate 3, the outer ends of the swinging rods 161 are connected to the supporting assembly 16, the highest point of the supporting assembly 16 is flush with the highest point of the middle position of the outer collecting frame 2, and on the basis of the first embodiment, the upper part of the inner air guide cover 8 can be propped up by the inner supporting plate 6, and then when the inner side wall of the gear blank is subjected to gear shaping processing, the debris generated at this time falls into the inner air guide cover 8 made of a funnel-shaped umbrella cloth material, and then the inner air guide cover 8 guides the debris to the inner collecting frame 81 below for collection and temporary storage;

[0062] When the outer wall of the gear blank is subjected to gear shaping, the debris generated at this time falls on the outer guide cover 9 which is inclined at the top. At this time, the outer support plate 7 stably supports the upper part of the outer guide cover 9, and at the same time, the outer guide cover 9 is supported by the support assembly 16, so that when the outer support plate 7 moves inward, the upper part of the outer guide cover 9 is well inclined, so that the debris generated when the outer wall of the gear blank is subjected to gear shaping can be guided along the outer side surface of the outer guide cover 9 to the annular collection groove 201 in the outer collection frame 2 for temporary collection and storage, and the debris in the collection groove 201 and the inner collection frame 81 can be cleaned out by external cleaning tools at a later time;

[0063] Embodiment 3: The high-precision wind power gearbox gear shaping processing tooling fixture in this embodiment, based on the embodiment 2, can further drop the debris on the outer side of the outer shroud 9 into the collection groove 201, thereby improving the efficiency of debris collection. Figure 9-12 As shown, the installation mechanism includes a support rod 162 installed in a groove opened on the outer side of the rotating control plate 3, the outer side of the support rod 162 passes through the swing rod 161, and a second vortex spring 163 is nested and connected to the outer side of one end of the support rod 162, and one end of the second vortex spring 163 is connected to the inside of the rotating control plate 3. A circle of automatic control blocks 17 are evenly installed on the upper surface of the middle part of the outer collection frame 2, and the two sides of the automatic control blocks 17 are arranged in an inclined structure; the swing rod 161 forms an up and down reciprocating rotation structure with the rotating control plate 3 through the automatic control block 17;

[0064] When the rotary control plate 3 rotates, it will drive the outer support assembly 16 to rotate together. At this time, the support assembly 16 revolves around the center of the rotating shaft 301. When the support assembly 16 drives the swing rod 161 to rotate until it contacts the automatic control block 17 at the corresponding position, at this time, since both sides of the automatic control block 17 are arranged in an inclined structure, the automatic control block 17 automatically pushes the swing rod 161 to rotate upward, so that the swing rod 161 rotates upward with the center of the support rod 162 as the center. At this time, the second vortex The spiral spring 163 accumulates force. When the automatic control block 17 is separated from the swing arm 161, the force accumulated by the second spiral spring 163 automatically drives the swing arm 161 and the support assembly 16 to rotate in the opposite direction and reset. As a result, the support assembly 16 rotates up and down reciprocatingly, causing the support assembly 16 to reciprocately shake the outer air duct 9 made of umbrella cloth material, thereby facilitating the shaking of debris on the outer side of the outer air duct 9 and dropping it into the collection groove 201 for collection, thereby improving the efficiency of debris collection and completing a series of tasks.
