Description

Technical Field

[0002] Wind turbines convert wind energy into electrical energy through the coordination of structures such as blades, gearboxes, and generators. Wind turbines are very large in size, and their gearboxes are also equipped with giant gears and gear rings.

[0003] There are many giant gears and gear rings used in wind power. The gears and gear rings are very large in size. The gears and gear rings need to be ground to remove burrs between the tooth blocks to ensure the smoothness of the gears and gear rings. Due to the huge size of the gears and gear rings, the gears and gear rings need to be clamped and fixed using multiple independently set fixing frames.

During the clamping process of multiple independently set fixing frames, position positioning measurements need to be performed multiple times. Each replacement of the gears and gear rings takes a long time. Summary of the invention

[0043] In the embodiment of the present disclosure, the upper pressure frame 304 and the upper fixed block 302 are slidably connected, and the two sides of the upper fixed block 302 extend to the outside of the two sides of the upper positioning frame 3.

[0045] The invention discloses a clamping method of a positioning clamping device for grinding wind power gears, comprising the following steps:

[0046] Fix the lower positioning frame 1 in the T-shaped connecting groove of the T-shaped groove workbench 4, and place the gear or gear ring component on the top plane of the upper positioning frame 3;

[0047] The upper connecting bracket 210 and the side connecting slot 202 are slidably inserted, and the side fixing pin 211 and the middle groove of the side connecting slot 202 are slidably inserted, and the upper connecting bracket 210 and the side connecting slot 202 are fixed in position;

[0048] The adjacent middle transmission shafts 203 are rotated synchronously through the first lower transmission shaft 205, the first transmission rod 206, the second transmission rod 207, and the second lower transmission shaft 208. The middle transmission shaft 203 drives the second screw rod 301 to rotate synchronously. The multiple upper positioning frames 3 move synchronously, and the upper positioning frames 3 move radially around the center.

[0049] The vertical surface of the upper fixing block 302 on the top of the upper positioning frame 3 fits the vertical surface of the gear or gear ring to fix the gear or gear ring, and the upper pressing frame 304 presses down the top surface of the lower gear or gear ring to fix it;

[0050] The rotation of the first screw rod 101 drives the middle positioning frame 2 to move horizontally, and the middle positioning frame 2 and the upper positioning frame 3 move synchronously to compensate for the error caused by the fixed position of the lower positioning frame 1 and the T-slot workbench 4.

[0051] Embodiment 2, on the basis of embodiment 1, one of the upper positioning frames 3 is provided with a motor to drive the middle transmission shaft 203 to rotate through gears. Only the motor needs to drive the middle transmission shaft 203 of one upper positioning frame 3, and the middle transmission shafts 203 of other upper positioning frames 3 can also rely on the transmission of the first lower transmission shaft 205, the first transmission rod 206, the second transmission rod 207, and the second lower transmission shaft 208 to rotate synchronously, eliminating the need for personnel to manually operate the middle transmission shaft 203.

[0052] The working principle of the first embodiment of the present invention is as follows: the T-slot worktable 4 can be fixedly connected to the worktable of the grinding equipment, and the T-slot worktable 4 rotates in a circular direction along with the worktable of the grinding equipment. The lower positioning frame 1 and the T-connecting slot bolts are tightened, and the number of lower positioning frames 1 is adjusted according to the size of the gear or gear ring that needs to be ground. The larger the gear or gear ring, the more lower positioning frames 1 are required to fix it, and the smaller the gear or gear ring, the smaller the gear or gear ring can be fixed with fewer lower positioning frames 1. There will be a certain error when the lower positioning frame 1 and the T-slot worktable 4 are fixed. By rotating the first screw 101, the middle positioning frame 2 moves axially horizontally along the thread outside the first screw 101, and the middle positioning frame 2 and the upper positioning frame 3 move synchronously. Dynamically supplement the error caused by the fixed position of the lower positioning frame 1 and the T-slot workbench 4, ensure that the multiple middle positioning frames 2 are equidistant from the center of the T-slot workbench 4, and realize the positioning and clamping of the gear or gear ring around the center of the T-slot workbench 4 by the multiple upper positioning frames 3, ensure that the center of the clamped gear or gear ring is aligned with the T-slot workbench 4, eliminate the work of re-positioning the gear or gear ring after processing, and eliminate the need for the grinding equipment to re-position the center of the circle after the gear or gear ring is supported, thereby reducing the positioning time and speeding up the processing efficiency of gear grinding. A retractable corrugated cover plate is arranged between the middle positioning frame 2 and the upper positioning frame 3 to cover the second screw 301, and the protection of the corrugated cover plate prevents iron filings from falling onto the second screw 301;

[0053] After the gear or gear ring is hoisted and placed horizontally on the plane of the upper positioning frame 3, the second screw 301 is rotated, and the thread of the second screw 301 guides the upper positioning frame 3 and the upper fixing block 302 to move synchronously close to the gear, and the vertical surface of the upper fixing block 302 fits the vertical surface of the gear or gear ring to fix the gear or gear ring in the horizontal direction, so as to achieve the clamping and fixing operation of the outer side or inner side of the gear or gear ring, and the middle lifting screw 303 is rotated, and the upper fixing block 302 is moved along the thread of the middle lifting screw 303. The upper fixing block 302 is pressed down to fit the top surface of the gear or gear ring to fix the gear or gear ring in the vertical direction, completing the vertical and horizontal fixing operations of the gear or gear ring. The upper connecting bracket 210 and the side connecting slot 202 are slidably inserted, and the side fixing pin 211 and the middle groove of the side connecting slot 202 are slidably inserted. The upper connecting bracket 210 and the side connecting slot 202 are fixed in position, and the middle transmission shaft 203 is engaged to drive the first lower transmission shaft 205 to rotate. The first lower transmission shaft 2 05 and the first transmission rod 206, the second transmission rod 207, and the second lower transmission shaft 208 rotate synchronously, the first lower transmission shaft 205 meshes to drive the middle transmission shaft 203 of the adjacent upper positioning frame 3 to rotate synchronously, and the upper end of the middle transmission shaft 203 meshes to drive the second screw 301 to rotate, so as to realize the synchronous movement of the upper positioning frame 3, and realize the synchronous movement of the adjacent upper positioning frames 3 by synchronizing the first lower transmission shaft 205, the first transmission rod 206, the second transmission rod 207, and the second lower transmission shaft 208. The multiple upper positioning frames 3 perform radial synchronous movement around the center of the T-slot workbench 4 to realize the annular clamping and fixing operation of the middle gear or gear ring, eliminating the need for the multiple upper positioning frames 3 to be fixed one by one, reducing the operation steps of clamping and tightening one by one, and realizing the center alignment and positioning of the gear or gear ring while clamping the multiple upper positioning frames 3, eliminating the need for multiple position positioning and measurement processes during the clamping process of multiple independently set fixing frames, and eliminating the situation where each replacement of the gear and gear ring requires a long time;

[0054] The first transmission rod 206 and the second transmission rod 207 are both hexagonal tube structures. The sliding and telescopic movement between the first transmission rod 206 and the second transmission rod 207 satisfies the power transmission work at different distances between the upper positioning frames 3. The lower rotating frame 204 rotates around the tail cylinder of the outer connecting frame 201, and the tail connecting rotating frame 209 rotates around the upper connecting plug frame 210. The tail connecting rotating frame 209 rotates around the middle transmission shaft 203. The rotation of the lower rotating frame 204 and the tail connecting rotating frame 209 is adjusted to adapt to the angle changes between the upper positioning frames 3 with different numbers of annular arrays, thereby achieving compatibility with different arrangement numbers of the upper positioning frames 3.
