The tooth number on both sides of the blade root can be selected according to the centrifugal force of the blade, and the strength is high and the adaptability is good.

When clamping the longitudinal number type blade root, the clamp body is usually manually opened first, the longitudinal number type blade root is placed into the clamping groove, the blade is located outside the clamp body, the clamp body is closed, and then the fixing bolt is inserted into the clamp body for fixation. When the longitudinal number type blade root needs to be taken out from the clamp, the fixing bolt is loosened and taken out first, then the clamp body is opened, and the longitudinal number type blade root is taken out from the clamping groove.

DETAILED DESCRIPTION

[0044] The following will be described in detail in combination with the accompanying drawings Figures 1-9 The application is further described in detail.

[0045] The embodiment of the application discloses a stable longitudinal tree type blade root grinding processing tool. Referring to Figure 1 The stable longitudinal tree type blade root grinding processing tool comprises a workbench 1, a clamping body 2, a lifting platform 3 and a lifting mechanism 4 are fixedly installed on the workbench 1, an installation through groove 11 for placing the lifting mechanism 4 is formed in the workbench 1, the shape of the installation through groove 11 can be adjusted according to actual conditions, the lifting platform 3 is installed on the workbench 1 through the lifting mechanism 4, the lifting platform 3 is located on one side of the clamping body 2, an installation recess 21 is formed on one side of the clamping body 2 close to the lifting platform 3, a support plate 22 and two clamping devices 23 are fixedly installed on the bottom wall of the installation recess 21; the top surface of the support plate 22 is flush with the top surface of the lifting platform 3, the two clamping devices 23 are respectively located on the two sides of the support plate 22, and when a blade root 5 is located on the support plate 22, the top surface of the blade root 5 abuts against the inner wall of the installation recess 21.

[0046] When assembling the blade root 5, first place the blade root 5 on the lifting platform 3. At this time, the top surface of the lifting platform 3 is flush with the top surface of the support plate 22. Push the blade root 5 into the mounting groove 21. When the blade root 5 is on the support plate 22, clamp the blade root 5 through the clamping device 23. Then push the blade root 5 into the mounting groove 21 through the clamping device 23. And lower the lifting platform 3 into the mounting through slot 11 through the lifting mechanism 4 so that the lifting platform 3 does not easily affect the grinding of the blade 51 on the blade root 5.

[0047] Reference Figure 1 , Figure 2 and Figure 3 Two mounting plates 221 are fixedly installed on both sides of the support plate 22 in the width direction, and the side walls on both sides of the blade root 5 abut against the mounting plates 221. When the blade root 5 is pushed into the mounting groove 21, the width direction of the blade root 5 is limited by the mounting plates 221 on both sides of the support plate 22, making the blade root 5 less likely to shake on the support plate 22 and improving the stability of the blade root 5 clamping.

[0048] Reference Figure 1 , Figure 4 and Figure 5 The lifting mechanism 4 includes a control component 41 and a lifting rod 42. The lifting rod 42 is fixedly connected to the inner wall of the mounting slot 11. A lifting groove 421 is provided on the lifting rod 42. A lifting block 422 is installed in the lifting groove 421, and the cross-section of the lifting block 422 is convex. The lifting groove 421 is adapted to the lifting block 422. A fixing rod 423 is fixedly connected to the lifting block 422. One end of the fixing rod 423 away from the lifting block 422 is fixedly connected to the bottom end of the lifting platform 3. When the lifting platform 3 needs to be raised or lowered, the control component 41 controls the lifting block 422 to rise or fall in the lifting groove 421, thereby causing the fixing rod 423 to drive the lifting platform 3 to rise or fall. The convex cross-section of the lifting groove 421 and the adaptation of the lifting block 422 to the lifting groove 421 make it difficult for the lifting block 422 to fall out of the lifting groove 421, thereby improving the stability of the installation of the lifting block 422.

[0049] Reference Figure 4 , Figure 5 and Figure 6A plurality of rotating plates 222 are connected to the mounting plate 221 by torsion springs 6, a plurality of mounting grooves 223 are formed in the support plate 22 near the mounting plate 221, and the rotating plates 222 are rotatably mounted in the mounting grooves 223 by the torsion springs 6. The control assembly 41 comprises a pushing assembly 411 and an eccentric wheel 412, the eccentric wheel 412 is rotatably connected to the lifting block 422 by a plurality of connecting rods 4121 which are hingedly connected to each other, the pushing assembly 411 is used for driving the eccentric wheel 412, and the pushing assembly 411 comprises a spring body 413 and a plurality of driving rods 414. In actual conditions, the eccentric wheel 412 and the driving rods 414 are relatively light in weight, a placing groove 211 for placing the spring body 413 is formed in the bottom end of the mounting recess 21, the spring body 413 is fixedly installed in the placing groove 211 and located directly below the mounting groove, the spring body 413 comprises a plurality of springs 4131 and a plurality of fixed plates 4132, the springs 4131 are fixedly connected to the fixed plates 4132, and the number of the springs 4131 can be adjusted according to actual needs; the fixed plate 4132 at the bottom end of the spring body 413 is fixedly connected to the bottom wall of the placing groove 211, an arc-shaped rod 2221 is fixedly connected to one side of the rotating plate 222 near the mounting groove 223, a fixing groove 2231 is formed in the bottom wall of the mounting groove 223, the arc-shaped rod 2221 penetrates through the fixing groove 2231 and is fixedly connected to the fixed plate 4132 at the top end of the spring body 413, and the fixed plate 4132 at the top end of the spring body 413 is fixedly connected to the driving rods 414, and the driving rods 414 are hingedly connected to the eccentric wheel 412 at the ends away from the spring body 413.

[0050] When the blade root 5 is pushed into the mounting recess 21, the blade root 5 pushes the rotating plate 222 to rotate into the mounting groove 223, so that the arc-shaped rod 2221 penetrates through the fixing groove 2231 and pushes the fixed plate 4132 at the top end of the spring body 413 to move downward. At this time, since the top surface of the blade root 5 abuts against the inner wall of the mounting recess 21, the blade root 5 and the clamping body 2 on the blade root 5 exert pressure on the springs 4131, so that the springs 4131 are compressed, thereby causing the driving rods 414 to start to move, the eccentric wheel 412 is driven to move, and finally the lifting platform 3 is pushed to descend. When the blade root 5 is moved out of the mounting recess 21, the blade root 5 is moved away from the rotating plate 222, the springs 4131 rebound, the rotating plate 222 is reset, the fixed plate 4132 at the top end of the spring body 413 pulls the driving rods 414 to move in the direction close to the lifting platform 3, the eccentric wheel 412 is pushed to move in the direction close to the lifting platform 3, thereby causing the lifting platform 3 to ascend upward until the top surface of the lifting platform 3 is flush with the top surface of the support plate 22, and facilitating the placement of the blade root 5 after the blade root 5 is moved out of the mounting recess 21.

[0052] When the blade root 5 is pushed into the installation groove 21, the blade root 5 presses the rotating plate 222, the rotating plate 222 presses the fixed plate 4132 at the top end of the spring body 413 through the arc-shaped rod 2221 to move downward, the first moving rod 4141 at one end close to the lifting platform 3 is driven to move downward, the first moving rod 4141 rotates around the rotating shaft 4144, the other end of the first moving rod 4141 far away from the lifting platform 3 is raised upward, the second moving rod 4142 is moved away from the lifting platform 3 through the first connecting part 4145 and the second connecting part 4146 abutting with each other, and the friction pad 4147 reduces the friction between the first connecting part 4145 and the second connecting part 4146, so that the first connecting part 4145 and the second connecting part 4146 are not easy to wear. The second moving rod 4142 pulls the eccentric wheel 412 to move away from the lifting platform 3, the eccentric wheel 412 moves the lifting block 422 downward through the connecting rod 4121, so that the lifting platform 3 is lowered. When the blade root 5 is moved out of the installation groove 21, the blade root 5 is removed from the rotating plate 222, the spring 4131 rebounds, the rotating plate 222 is reset, the fixed plate 4132 at the top end of the spring body 413 pulls the first moving rod 4141 to move close to the lifting platform 3, the first moving rod 4141 pulls the second moving rod 4142 to move close to the lifting platform 3, so as to push the eccentric wheel 412 to move close to the lifting platform 3, so that the lifting platform 3 is raised upward to the top surface of the lifting platform 3 is flush with the top surface of the supporting plate 22, facilitating the placement of the blade root 5 after being moved out of the installation groove 21. The first connecting part 4145 and the second connecting part 4146 realize automatic control of the lifting of the lifting platform 3, and the efficiency of the lifting of the lifting platform 3 is improved.

[0053] With reference to Figure 7 , the first connecting part 4145 and the second connecting part 4146 are provided with fixing holes 4148, and the fixing member 4143 is a fixed bolt which passes through the fixing holes 4148 and is threadedly connected with the nut. When the first moving rod 4141 pushes the second moving rod 4142 to move through the first connecting part 4145 and the second connecting part 4146 abutting with each other, the fixed bolt passes through the fixing holes 4148 to fix the first connecting part 4145 and the second connecting part 4146 with each other, so that the second moving rod 4142 is not easy to fall off from the first moving rod 4141 during the movement when the first moving rod 4141 and the second moving rod 4142 move together, and the first moving rod 4141 drives the second moving rod 4142 to move.

[0054] With reference to Figure 1 and Figure 3The clamping device 23 comprises two groups of sliding assemblies 231 and two groups of push rods 232, the sliding assemblies 231 are used for driving the push rods 232 to slide automatically, each push rod 232 is slidably installed in the mounting groove 21 through a group of sliding assemblies 231, the push rod 232 comprises a first rod body 2321 and a second rod body 2322, the first rod body 2321 is closer to the lifting platform 3 than the second rod body 2322, a connecting plate 2323 is rotatably connected to the first rod body 2321 through a torsion spring 6, a blocking rod 2324 is fixedly connected to the second rod body 2322, the connecting plate 2323 can be rotated to abut against a side wall of the blade root 5, at this time, the blocking rod 2324 abuts against an end of the blade root 5 which is away from the lifting platform 3, the length of the connecting plate 2323 is less than the length of the blocking rod 2324, and the length of the connecting plate 2323 can be adjusted according to actual needs. The tool for grinding the longitudinal tree type blade root further comprises a limiting piece 7, the limiting piece 7 is detachable with the clamping body 2, when the blade root 5 is pushed into the mounting groove 21, the connecting plate 2323 is rotated away from the lifting platform 3, and the limiting piece 7 is used for limiting the connecting plate 2323 from rotating towards the lifting platform 3; when the limiting piece 7 removes the limitation on the connecting plate 2323, the connecting plate 2323 can rotate towards the lifting platform 3.

[0055] When the blade root 5 is assembled, the blade root 5 is first pushed into the mounting groove 21 until an end of the blade root 5 close to the mounting groove 21 abuts against the connecting plate 2323 on the first rod body 2321, and then the blade root 5 is further pushed into the mounting groove 21, so that the connecting plate 2323 is rotated to abut against the end wall of the blade root 5, the blade root 5 can continue to be pushed into the mounting groove 21, and the rotation of the connecting plate 2323 is limited by the limiting piece 7, so that the connecting plate 2323 cannot rotate towards the lifting platform 3, and the blocking rod 2324 on the second rod body 2322 cooperates with the connecting plate 2323 to clamp the blade root 5; when the blade root 5 needs to be removed from the mounting groove 21, the limiting piece 7 is detached from the clamping body 2, the limiting piece 7 removes the limitation on the connecting plate 2323, the connecting plate 2323 rotates towards the lifting platform 3, and the blade root 5 is moved to the opening of the mounting groove 21 through the blocking rod 2324 on the second rod body 2322 until the blade root 5 is removed from the mounting groove 21, so that the blade root 5 is clamped.

[0056] Referring to Figure 3 and Figure 8The sliding assembly 231 comprises a driving assembly 234 and a sliding table 235. The sliding table 235 is provided with a sliding groove 2351 penetrating through two sides of the sliding table 235 along the length direction of the sliding table 235. A sliding block 2352 is slidably arranged in the sliding groove 2351. The push rod 232 is fixedly connected to the sliding block 2352. The driving assembly 234 comprises a driving motor 2341, a synchronous assembly 2342 and two screw rods 2343. The rotating shaft of the driving motor 2341 is connected to the screw rods 2343 through the synchronous assembly 2342. The screw rods 2343 penetrate through the corresponding sliding blocks 2352 and are threadedly connected to the sliding blocks 2352.

[0057] With reference to Figure 8 The synchronous assembly 2342 comprises a synchronous belt 2344, one synchronous driving wheel 2345 and two synchronous driven wheels 2346. The two synchronous driven wheels 2346 are respectively located on the two sides of the synchronous driving wheel 2345. The synchronous driving wheel 2345 is connected to the rotating shaft of the driving motor 2341 and coaxially arranged. The rotating shafts of the two synchronous driven wheels 2346 are respectively connected to the corresponding screw rods 2343 and coaxially arranged. The synchronous driving wheel 2345 and the synchronous driven wheels 2346 are matched with the synchronous belt 2344. When the blade root 5 is moved, the driving motor 2341 is driven to start rotating the synchronous driving wheel 2345. The screw rods 2343 are driven to start rotating through the synchronous belt 2344, thereby driving the two push rods 232 to start rotating. Finally, one driving motor 2341 drives the push rods 232 on the two sides of the blade root 5 to move simultaneously, improving the driving efficiency of the driving motor 2341 and saving energy consumption.

[0058] With reference to Figure 3 and Figure 9The limiting member 7 comprises a limiting rod 71, and limiting holes 72 are formed on the first rod body 2321 near the lifting platform 3 and on the sliding block 2352. The limiting hole 72 on the first rod body 2321 is closer to the lifting platform 3 than the connecting plate. When the connecting plate 2323 is rotated to abut against the side wall of the blade root 5, one end of the limiting rod 71 passes through the limiting hole 72 to limit the rotation of the connecting plate 2323. The other end of the limiting rod 71 passes through the limiting hole 72 on the sliding block 2352 and is clamped on the sliding block 2352. A limiting groove 24 is formed on the inner wall of the mounting groove 21 for the limiting rod 71 to slide. The limiting rod 71 is away from the first rod body 2321 and is located outside the clamping body 2. When the connecting plate 2323 is rotated to abut against the end wall of the blade root 5, one end of the limiting rod 71 passes through the limiting hole 72 on the first rod body 2321, and the other end passes through the limiting hole 72 on the sliding block 2352. The limiting rod 71 limits the rotation of the connecting plate 2323 so that it cannot rotate towards the lifting platform 3. When the blade root 5 needs to be moved out of the mounting groove 21, the limiting rod 71 is detached from the clamping body 2. The limiting rod 71 removes the limitation on the connecting plate 2323. With the movement of the blade root 5, the connecting plate 2323 rotates towards the lifting platform 3. The rotation of the connecting plate 2323 is limited, thereby further clamping the blade root 5 and improving the stability of the blade root 5.

[0059] The implementation principle of the stable longitudinal number type blade root grinding tooling device is as follows: when the longitudinal number type blade root 5 is assembled, the top surface of the lifting table 3 is flush with the top surface of the supporting plate 22, and the end of the supporting plate 22 near the opening of the mounting groove 21 is adjacent to the lifting table 3. The blade root 5 is placed on the lifting table 3, and the blade root 5 is pushed away from the lifting table 3. The connecting plate 2323 on the first rod body 2321 is rotated into the mounting groove 21 under the pressure of the blade root 5 pushing inward, until the blade root 5 can continue to be pushed away from the lifting table 3 and the side wall of the connecting plate 2323 abuts against the end wall of the blade root 5. At this time, the blocking rod 2324 on the second rod body 2322 abuts against the end of the blade root 5 away from the lifting table 3. The connecting plate 2323 and the blocking rod 2324 cooperate to clamp the blade root 5. The blade root 5 is pushed into the clamping body 2 by the sliding assembly 231, until it abuts against the rotating plate 222. At this time, the blade root 5 and the clamping body 2 above the blade root 5 apply pressure to the rotating plate 222, so that the rotating plate 222 is rotated to be located in the mounting groove 223, thereby driving the lifting mechanism 4 to move the lifting table 3 downward to be located in the mounting through groove 11, so that the lifting table 3 is not easy to affect the blade 51 of the longitudinal number type blade root 5 to be machined; when the blade root 5 needs to be removed, first move the blade root 5 away from the rotating plate, so that the spring 4131 at the bottom end of the rotating plate 222 can be reset, thereby driving the lifting mechanism 4 to lift the lifting table 3 to be flush with the top surface of the supporting plate 22, and then moving the blade root 5 to the direction close to the lifting table 3 by the sliding assembly 231, until the blade root 5 is pushed out of the clamping body 2 on the lifting table 3, and then the blade root is taken away.

[0060] The above are preferred embodiments of the present application, and do not limit the protection scope of the present application. Therefore, equivalent changes made on the basis of the structure, shape and principle of the present application should be covered within the protection scope of the present application.
