Description

Technical Field

[0001] The present invention belongs to the technical field of planet carrier processing, and particularly relates to an automatic clamping device for planet carrier processing and a using method thereof. Background Art

[0002] Planet carriers are divided into integral planet carriers and split planet carriers. When processing split planet carriers, there are advantages such as high material utilization rate, low requirements for equipment, and easy control of heat treatment deformation. Therefore, existing planet carriers are mostly split planet carriers. The split planet carrier includes flange plates at both ends and an intermediate web. The two flange plates are welded or bolt-connected through the intermediate web.

[0003] The flange plates are castings or forgings, and the surfaces of the flange plates need to be processed. The surface processing of the flange plates involves the processing of both ends, inner walls, and side walls. When the existing flange plates are processed at both ends, inner walls, and side walls, they need to be clamped and processed separately. For example, a flange plate processing device for valve processing disclosed in the publication number CN222449378U fixes the inner wall of the flange plate through multiple abutting outer rods, and a positioning fixture for exhaust pipe flange plate processing disclosed in the publication number CN222114320U clamps the side wall of the flange plate through two fixed clamping plates.

[0004] When the above devices fix the side wall and inner wall of the flange plate, the fixed side wall and the blocked end cannot be processed. Therefore, the flange plate needs to be clamped and disassembled on different jigs multiple times, resulting in troublesome processing of the flange plate and requiring multiple clamping tools to achieve the surface processing of the flange plate. During mass production, frequent clamping and disassembly of the flange plate affect the processing efficiency of the flange plate. Summary of the Invention

[0022] Compared with the prior art, the present invention has the following beneficial effects:

[0049] In order to make the objectives, technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0050] The following will describe the specific implementation of the present invention in detail in conjunction with specific embodiments.

[0051] As Figures 1 - 5 shown, a kind of automatic clamping device for planet carrier processing provided by an embodiment of the present invention includes a mounting frame 101, and further includes: a flipping ring 102 rotatably connected to the mounting frame 101, a first motor 103 fixed on the side wall of the mounting frame 101, and the rotating end of the first motor 103 is connected to the rotating axis center of the flipping ring 102; a rotating ring 104 is rotatably connected to the flipping ring 102, and a side wall clamping mechanism 2 is arranged on the rotating ring 104, and the side wall clamping mechanism 2 is used for clamping the side wall of the flange; a moving plate 105 is arranged on one side of the flipping ring 102, a rotating disk 106 is rotatably connected to the moving plate 105, and an inner wall clamping mechanism 3 is arranged on the rotating disk 106, and the inner wall clamping mechanism 3 is used for clamping the inner wall of the flange; a rotating assembly one 5 for driving the rotating ring 104 and the rotating disk 106 to rotate is arranged on the mounting frame 101.

[0052] In the embodiment of the present invention, when processing the flange, the flange is placed in the rotating ring 104 by means of a manipulator or manually. The side wall clamping mechanism 2 clamps the side wall of the flange, and the rotating assembly one 5 drives the rotating ring 104 to rotate. The rotating ring 104 drives the flange to rotate, and the tool processes the inner wall and one end of the flange respectively. After the inner wall and one end of the flange are processed, the moving assembly 4 drives the rotating disk 106 away from the rotating ring 104, and the first motor 103 drives the flipping ring 102 to flip. The flipping ring 102 drives the flange to flip, so that the other end of the flange is in the processing station, and by controlling the flipping ring 102 to flip quickly, the processing debris and cutting fluid on the flange can be shaken off to clean the flange;

[0053] The moving assembly 4 drives the moving plate 105 and the rotating disk 106 to approach the rotating ring 104. The moving plate 105 abuts against the flipping ring 102, thereby restricting the rotation of the flipping ring 102, avoiding the rotation of the flipping ring 102 driven by the force of the flange during the processing of the flange, improving the stability of the flange processing. The inner wall clamping mechanism 3 clamps the inner wall of the flange, the side wall clamping mechanism 2 releases the side wall of the flange, the rotating assembly one 5 drives the rotating ring 104 to rotate, the rotating ring 104 drives the flange to rotate, and the tool processes the side wall and the other end of the flange. After the side wall and the other end of the flange are processed, the flange is fixed by a manipulator or manually, the inner wall clamping mechanism 3 releases the inner wall of the flange, and the flange is unloaded by a manipulator or manually, thereby reducing the number of times of manual clamping and disassembling the flange, and reducing the number of flange fixtures, and improving the processing efficiency of the flange.

[0054] As Figure 1 and Figure 2As shown in the figure, as a preferred embodiment of the present invention, the moving component 4 includes two horizontal guiding shafts 401 fixed to one end of the moving plate 105 away from the flipping ring 102. Both of the two horizontal guiding shafts 401 are slidably connected to the mounting frame 101. An electric telescopic rod 402 is fixed to the mounting frame 101, and the telescopic end of the electric telescopic rod 402 is connected to the moving plate 105.

[0055] In the embodiment of the present invention, when the electric telescopic rod 402 extends, under the guiding action of the guiding shaft 401, the electric telescopic rod 402 drives the moving plate 105 to approach the flipping ring 102. The moving plate 105 abuts against the flipping ring 102, thereby restricting the rotation of the flipping ring 102. When processing the flange, due to the force on the flange, the flange and the flipping ring 102 rotate, which improves the stability of flange processing. The moving plate 105 drives the rotating disk 106 to approach the rotating ring 104;

[0056] When the electric telescopic rod 402 contracts, under the guiding action of the guiding shaft 401, the electric telescopic rod 402 drives the moving plate 105 to move away from the flipping ring 102. The moving plate 105 drives the rotating disk 106 to move away from the rotating ring 104, thereby providing space for the flipping of the flipping ring 102.

[0057] As Figure 1 、 Figure 2 、 Figure 5 、 Figure 6 and Figure 7 As shown in the figure, as a preferred embodiment of the present invention, the first rotating component 5 includes a sliding rod 502 fixed to one end of the rotating disk 106 away from the flipping ring 102. A driving sleeve 501 is slidably connected to the sliding rod 502 along the length direction. The driving sleeve 501 is rotatably connected to the mounting frame 101. The driving sleeve 501 is driven to rotate by the rotating end of a servo motor or a machine tool. A third guiding groove 504 is provided on the rotating disk 106. A connecting block 505 is slidably connected in the third guiding groove 504. One end of the connecting block 505 is fixed with a first compression spring 506, and the end of the first compression spring 506 is fixed in the third guiding groove 504. A connecting hole 503 is provided on the rotating ring 104, and the other end of the connecting block 505 is matched with the connecting hole 503.

[0058] In the embodiment of the present invention, when the moving plate 105 and the rotating disk 106 approach the flipping ring 102 and the rotating ring 104, the connecting block 505 is inserted into the connecting hole 503. The rotating end of the servo motor or the machine tool drives the driving sleeve 501 to rotate. The driving sleeve 501 drives the rotating disk 106 to rotate. The rotating disk 106 drives the inner wall clamping mechanism 3 to rotate. The rotating disk 106 drives the connecting block 505 to rotate. The connecting block 505 drives the rotating ring 104 to rotate through the connecting hole 503. The rotating ring 104 drives the side wall clamping mechanism 2 to rotate.

[0059] As shown in Figure 1 , Figure 3 and Figure 4 , as a preferred embodiment of the present invention, the side wall clamping mechanism 2 includes a first guiding groove 201 annularly and evenly arranged on the rotating ring 104. A first clamping slider 202 is slidably connected in each of the three first guiding grooves 201. A first transmission shaft 203 is fixed on the side wall of each of the three first clamping sliders 202. A first transmission ring 204 is rotatably connected in the rotating ring 104. Three arc-shaped grooves 205 are evenly arranged on the first transmission ring 204. The three first transmission shafts 203 are respectively slidably connected in the three arc-shaped grooves 205. A first driving shaft 206 is rotatably connected to the rotating ring 104. The first driving shaft 206 is threadedly connected to one of the first clamping sliders 202.

[0060] In the embodiment of the present invention, in the initial state, the three first clamping sliders 202 are far away from each other. Place the flange between the three first clamping sliders 202 and rotate the first driving shaft 206. Under the guiding action of one of the first guiding grooves 201, the first driving shaft 206 drives one of the first clamping sliders 202 to move through a threaded transmission manner. One of the first clamping sliders 202 can drive the first transmission ring 204 to rotate through the cooperation of one set of the first transmission shaft 203 and the arc-shaped groove 205. The first transmission ring 204 drives the other two first clamping sliders 202 to move synchronously through the cooperation of the other two sets of the first transmission shaft 203 and the arc-shaped groove 205, and the guiding action of the other two first guiding grooves 201, so that the three first clamping sliders 202 move towards each other synchronously, and the three first clamping sliders 202 clamp the side wall of the flange. The thread on the first driving shaft 206 adopts a self-locking thread, which plays a self-locking role in fixing the flange after the flange is fixed, so that the flange is stably fixed.

[0061] When loosening the side wall of the flange, reverse the first driving shaft 206. Under the guiding action of one of the first guiding grooves 201, the first driving shaft 206 drives one of the first clamping sliders 202 to move in the reverse direction through a threaded transmission manner. One of the first clamping sliders 202 can drive the first transmission ring 204 to reverse through the cooperation of one set of the first transmission shaft 203 and the arc-shaped groove 205. The first transmission ring 204 drives the other two first clamping sliders 202 to move synchronously in the reverse direction through the cooperation of the other two sets of the first transmission shaft 203 and the arc-shaped groove 205, and the guiding action of the other two first guiding grooves 201, so that the three first clamping sliders 202 move in the reverse direction synchronously, and the three first clamping sliders 202 loosen the side wall of the flange.

[0062] As shown in Figure 1 , Figure 2 , Figure 5 , Figure 6 , Figure 7 , Figure 8 ,Figure 9 and Figure 10 As shown in Figure 10 , as a preferred embodiment of the present invention, the inner wall clamping mechanism 3 includes three second guiding grooves 301 uniformly arranged in a ring on the rotating disk 106. A second clamping slider 302 is slidably connected in each of the three second guiding grooves 301. A clamping block 303 is arranged at one end of each of the three second clamping sliders 302 close to the flipping ring 102. A second transmission shaft 304 is fixed on the side wall of each of the three second clamping sliders 302. A second transmission ring 305 is rotatably connected in the rotating disk 106. Three second arc grooves 306 are uniformly arranged in a ring on the second transmission ring 305. The three second transmission shafts 304 are respectively slidably connected in the three second arc grooves 306. A second driving shaft 307 is rotatably connected in the rotating disk 106. The second driving shaft 307 is threadedly connected to one of the second clamping sliders 302. The clamping block 303 is slidably connected to the second clamping slider 302. A third transmission shaft 601 is fixed on the side wall of the clamping block 303. An avoidance groove 602 for avoiding the movement of the third transmission shaft 601 is arranged on the side wall of the second clamping slider 302. A sunken groove 603 and a holding sunken groove 604 which are communicated are arranged on the inner wall of the second guiding groove 301. The length direction of the holding sunken groove 604 is horizontal with the moving direction of the second clamping slider 302. The sunken groove 603 is inclined.

[0063] In the embodiment of the present invention, in the initial state, the three second clamping sliders 302 are close to each other, and the clamping block 303 retracts into the second clamping slider 302. When clamping the inner wall of the clamping flange, rotate the second driving shaft 307. Under the guiding action of one of the second guiding grooves 301, the second driving shaft 307 drives one of the second clamping sliders 302 to move through a threaded transmission manner. One of the second clamping sliders 302 can drive the second transmission ring 305 to rotate through the cooperation of one set of the second transmission shafts 304 and the second arc grooves 306. The second transmission ring 305 drives the other two second clamping sliders 302 to move synchronously through the cooperation of the other two sets of the second transmission shafts 304 and the second arc grooves 306 and the guiding action of the other two second guiding grooves 301, so as to make the three second clamping sliders 302 move synchronously in the opposite direction. When the second clamping slider 302 moves, it can drive the clamping block 303 and the third transmission shaft 601 to move. The third transmission shaft 601 moves in the sunken groove 603. The sunken groove 603 pushes the third transmission shaft 601 to move towards the outside of the second guiding groove 301. The third transmission shaft 601 drives the clamping block 303 to extend out of the second clamping slider 302 until the third transmission shaft 601 slides into the holding sunken groove 604, and the clamping block 303 completely extends out of the second clamping slider 302. The three clamping blocks 303 clamp and fix the inner wall of the flange. The thread on the second driving shaft 307 adopts a self-locking thread, which plays a role of self-locking in fixing the flange after fixing the flange, so that the flange is stably fixed.

[0064] When loosening the side wall of the flange, reverse the drive shaft two 307. Under the guiding action of one of the guiding grooves two 301, the drive shaft two 307 drives one of the clamping sliders two 302 to move in the reverse direction through a threaded drive. One of the clamping sliders two 302 can drive the transmission ring two 305 to reverse through the cooperation of one set of transmission shafts two 304 and the arc groove two 306. The transmission ring two 305 drives the other two clamping sliders two 302 to move synchronously in the reverse direction through the cooperation of the remaining two sets of transmission shafts two 304 and the arc groove two 306, and the guiding action of the remaining two guiding grooves two 301, so that the three clamping sliders two 302 move synchronously towards each other. The three clamping sliders two 302 drive the three clamping blocks 303 to move synchronously towards each other, so that the three clamping blocks 303 loosen the inner wall of the flange. The clamping block 303 drives the transmission shaft three 601 to move within the holding groove 604 until the transmission shaft three 601 slides into the sinking groove 603. The sinking groove 603 drives the transmission shaft three 601 to retract into the guiding groove two 301. The transmission shaft three 601 drives the clamping block 303 to retract into the clamping slider two 302, so that the clamping block 303 disengages from the inner side of the flange, providing space for the tool to machine the inner wall of the flange.

[0065] Such as Figure 1 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 11 , Figure 12 , Figure 13 and Figure 14As shown, as a preferred embodiment of the present invention, driving mechanisms 7 are provided on both the mounting frame 101 and the moving plate 105. The two driving mechanisms 7 are respectively used to drive the first driving shaft 206 and the second driving shaft 307 to rotate. The driving mechanism 7 includes a sliding groove 701 provided on the mounting frame 101 or the moving plate 105. A sliding block 702 is slidably connected in the sliding groove 701. An electric telescopic rod two 703 is fixed on the side walls of the mounting frame 101 and the moving plate 105. The telescopic end of the electric telescopic rod two 703 is connected to the sliding block 702. A rotating component two 8 for driving the first driving shaft 206 or the second driving shaft 307 to rotate is provided on the sliding block 702. The rotating component two 8 includes a second motor 801 fixed on the side wall of the mounting frame 101 or the moving plate 105. A rotating shaft 802 is fixed to the rotating end of the second motor 801. A rotating sleeve 803 is slidably connected to the rotating shaft 802 along the length direction. The sliding block 702 is rotatably connected to the rotating sleeve 803. A transmission block 804 is slidably connected to the end of the rotating sleeve 803 along the length direction. One end of the transmission block 804 is fixed with a compression spring two 805. The compression spring two 805 is fixed in the rotating sleeve 803. The other end of the transmission block 804 is regular hexagon-shaped, and regular hexagon-shaped sinking grooves are provided at the ends of both the first driving shaft 206 and the second driving shaft 307. A limiting sinking groove 806 is provided at the position of the side wall of the rotating ring 104 at the end of the first driving shaft 206.

[0066] In the embodiment of the present invention, in the initial state, the two electric telescopic rods two 703 are in a contracted state, and the two transmission blocks 804 are far away from the flipping ring 102 and the moving plate 105;

[0067] When it is necessary to rotate the first driving shaft 206 or the second driving shaft 307, the electric telescopic rod two 703 extends. Under the guiding action of the sliding groove 701, the electric telescopic rod two 703 drives the sliding block 702 to move. The sliding block 702 drives the rotating sleeve 803 to move. The rotating sleeve 803 drives the transmission block 804 to move, so that the transmission block 804 is inserted into the regular hexagon-shaped sinking groove at the end of the first driving shaft 206 or the second driving shaft 307. The second motor 801 drives the rotating shaft 802 to rotate. The rotating shaft 802 drives the rotating sleeve 803 to rotate. The rotating sleeve 803 drives the transmission block 804 to rotate. The transmission block 804 drives the first driving shaft 206 or the second driving shaft 307 to rotate, and the inner wall clamping mechanism 3 can be controlled to clamp or release the inner wall of the flange, and the side wall clamping mechanism 2 can be controlled to clamp or release the side wall of the flange. After the rotation of the first driving shaft 206 or the second driving shaft 307 ends, the electric telescopic rod two 703 contracts, and the transmission block 804 is far away from the flipping ring 102 or the moving plate 105;

[0068] When the moving plate 105 is away from the flipping ring 102 and the flipping ring 102 needs to rotate, one of the electric telescopic rods II 703 extends, and the rotating sleeve 803 is inserted into the limiting sunk groove 806 to limit the rotation of the rotating ring 104 and prevent the rotating ring 104 from rotating when the flipping ring 102 rotates.

[0069] In the above embodiment of the present invention, a kind of automatic clamping device for planet carrier processing is provided. When processing the flange, the flipping ring 102 and the moving plate 105 are attached together. The flange is placed in the rotating ring 104 by means of a manipulator or manually. One of the rotating assemblies II 8 drives the driving shaft I 206 to rotate. Under the guiding action of one of the guiding grooves I 201, the driving shaft I 206 drives one of the clamping sliders I 202 to move through screw drive. One of the clamping sliders I 202 can drive the transmission ring I 204 to rotate through the cooperation of one set of transmission shafts I 203 and the arc-shaped groove I 205. The transmission ring I 204 drives the other two clamping sliders I 202 to move synchronously through the cooperation of the remaining two sets of transmission shafts I 203 and the arc-shaped groove I 205, and under the guiding action of the remaining two guiding grooves I 201, so that the three clamping sliders I 202 move towards each other synchronously, and the three clamping sliders I 202 clamp the side wall of the flange.

[0070] The rotating end of the servo motor or the machine tool drives the driving sleeve 501 to rotate. The driving sleeve 501 drives the rotating disk 106 to rotate. The rotating disk 106 drives the connecting block 505 to rotate. The connecting block 505 drives the rotating ring 104 to rotate through the connecting hole 503. The rotating ring 104 drives the flange to rotate, and the tool processes the inner wall and one end of the flange respectively.

[0071] After the inner wall and one end of the flange are processed, the electric telescopic rod I 402 contracts. Under the guiding action of the guiding shaft 401, the electric telescopic rod I 402 drives the moving plate 105 away from the flipping ring 102. The moving plate 105 drives the rotating disk 106 away from the rotating ring 104, thereby providing space for the flipping of the flipping ring 102. The first motor 103 drives the flipping ring 102 to flip. The flipping ring 102 drives the flange to flip, so that the other end of the flange is in the processing station. The electric telescopic rod I 402 extends. Under the guiding action of the guiding shaft 401, the electric telescopic rod I 402 drives the moving plate 105 to approach the flipping ring 102, and the connecting block 505 is inserted into the connecting hole 503.

[0072] Another rotating assembly II 8 drives the driving shaft II 307 to rotate, controls the inner wall clamping mechanism 3 to clamp the inner wall of the flange, and one of the rotating assemblies II 8 drives the driving shaft I 206 to reverse, and the side wall clamping mechanism 2 releases the side wall of the flange.

[0073] The rotation assembly 1 drives the rotation ring 104 to rotate, and the rotation ring 104 drives the flange to rotate. The tool processes the side wall and the other end of the flange. After the processing of the side wall and the other end of the flange is completed, the flange is fixed by a manipulator or manually. Another rotation assembly 2 drives the second shaft 307 to reverse, controls the inner wall clamping mechanism 3 to release the inner wall of the flange, and the flange is unloaded by a manipulator or manually, thereby reducing the number of times of manually clamping and disassembling the flange, reducing the number of flange fixtures, and improving the processing efficiency of the flange.

[0074] A method for using an automatic clamping device for planet carrier processing, based on the above-mentioned automatic clamping device for planet carrier processing, includes the following steps:

[0075] Step 1: Place the flange in the rotation ring 104, and the side wall clamping mechanism 2 clamps the side wall of the flange.

[0076] Step 2: The rotation assembly 1 drives the rotation ring 104 to rotate, and the rotation ring 104 drives the flange to rotate. The tool processes the inner wall and one end of the flange.

[0077] Step 3: The moving assembly 4 drives the rotating disk 106 away from the rotation ring 104, and the first motor 103 drives the flipping ring 102 to flip, and the flipping ring 102 drives the flange to flip.

[0078] Step 4: The moving assembly 4 drives the rotating disk 106 to approach the rotation ring 104.

[0079] Step 5: The inner wall clamping mechanism 3 clamps the inner wall of the flange, and the side wall clamping mechanism 2 releases the side wall of the flange.

[0080] Step 6: The rotation assembly 1 drives the rotation ring 104 to rotate, and the rotation ring 104 drives the flange to rotate. The tool processes the side wall and the other end of the flange.
