[0015] A processing method of a chamfering device for processing an internal bearing of an air circuit breaker, comprising the following processing steps:

[0016] The first step: during continuous operation, as the clamping assembly in the vertical state cooperates with the chamfering processing mechanisms on both sides to realize the processing of the outer ring of the bearing, the deflection assembly drives the swing support assembly to rotate to a horizontal state, so that the clamping assembly is located between the loading frame and the reserved frame of the quick switching assembly, and the opening and closing assembly is squeezed and contacted with the fixed push plate during movement, bypassing the pressure air inside the clamping assembly, canceling the clamping and fixing of the outer ring of the bearing, and at the same time, the quick switching assembly pushes the bearing to be processed into the clamping assembly, and automatically pushes the processed outer ring of the bearing into the reserved frame, starts the deflection assembly and drives the clamping assembly to reset to a vertical state, and the opening and closing assembly is re-sealed when the clamping assembly is away from the fixed push plate, the internal pressure of the clamping assembly is restored and the outer ring of the bearing is clamped, and the clamping assembly is swung back to a vertical state, at this time, the arc baffle in the blocking assembly swings into the quick switching assembly, and the notch is aligned with the reserved frame, the outer ring of the bearing processed in the reserved frame is elastically pushed to the notch and falls into the arc cavity, and falls out along the blanking port, completing the switching and discharging;

[0017] Step 2: After resetting to vertical, the chamfering mechanisms on both sides are brought close together and chamfering is performed;

[0018] Step 3: Start the vacuum pump at the same time, and the vacuum pump will suck the dust particles in the processing process into the arc cavity;

[0019] Step 4: After the processing is completed, the clamping assembly is swung to a horizontal state again to quickly load and unload the material. At the same time, the blocking assembly pushes the impurities collected in the arc cavity upward along the arc cavity to complete the unified collection and cleaning, waiting for the next swing-up reset processing.

[0020] The beneficial effects of the present invention are as follows:

[0021] 1. The present invention realizes the swing control of the swing support assembly by utilizing the deflection assembly. When the swing support assembly and the clamping assembly are located vertically above, the chamfering processing mechanisms on both sides are cooperated to complete the double-sided chamfering. When the swing support assembly and the clamping assembly are swung to the horizontal state, the outer ring of the bearing is automatically pushed to the clamping assembly through the position control of the quick switching assembly. As the clamping assembly cooperates with the gas continuously output in the swing support assembly, after the clamping assembly swings and staggers with the fixed push plate, the clamping head re-clamps the outer ring of the bearing in the positioning ring under the action of gas pressure, and the loading and automatic clamping of the bearing are quickly completed. At the same time, the reserved frame and the spring are used to clamp the outer ring of the bearing in the clamping assembly. After swinging upward, the arc-shaped baffle rotates accordingly. On the one hand, it realizes sealing on one side of the loading frame to prevent the bearing from falling out of the loading frame. On the other hand, it utilizes the notch on the other side of the arc-shaped baffle to realize the automatic pushing out and dropping of the outer ring of the bearing after processing in the reserved frame. Therefore, for the chamfering processing of large quantities of bearing outer rings, it can realize continuous and rapid loading while automatically completing the positioning and clamping of the bearing outer ring after loading, and can also realize automatic withdrawal of the bearing outer ring after processing during continuous loading. The entire continuous processing production efficiency is extremely high, and loading, positioning, clamping, and double-sided chamfering are realized continuously and quickly, and unloading is completed at the same time as loading, reducing intermediate operations and greatly improving production and processing efficiency.

[0022] 2. The present invention utilizes the swinging action of the clamping assembly again. When the clamping assembly is swung up to a vertical state for chamfering, the sealing arc block in the blocking assembly is ensured to open the local space of the arc cavity, and the vacuum pump is used to suck the debris generated by the chamfering and concentrate it into the arc cavity. When the clamping assembly is rotated to a horizontal state for loading and unloading, the sealing arc block is driven to rotate upward and slide along the inside of the arc cavity, and the collected debris is uniformly pushed to the top of the processing table. The collected debris can be directly recycled and processed in a unified manner, avoiding the need for complex and large-scale cleaning operations for scattered debris and impurities, greatly reducing the difficulty of subsequent cleaning and recycling, and having a good use effect.

[0037] The quick switching assembly 13 includes a loading frame 131 , a reserved frame 132 , a third spring 133 , a loading port 134 , a second electric push rod 135 and a limit stopper 136 .

[0038] Embodiment 1: During the initial operation, multiple groups of bearing outer rings to be processed are inserted along the opening of the loading frame 131, and then the No. 1 electric push rod 82 pushes the toothed plate 83 to move horizontally and drives the meshing gear 84 to rotate, driving a group of support shafts 6 to rotate, so that the support plate 71 swings to a horizontal state and is located between the loading frame 131 and the reserved frame 132, and at the same time drives the positioning ring 101 to be located between the loading frame 131 and the reserved frame 132, and the No. 2 electric push rod 135 drives the limit stopper 136 to push multiple groups of bearing outer rings to move horizontally synchronously, and the outermost bearing outer ring is pushed to the inside of the positioning ring 101 and contacts the spring three 133 on the other side, and the push stops. At this time, since the positioning ring 101 swings to a horizontal state, the stop rod 113 of the internal opening and closing assembly 11 The fixed push plate 12 is squeezed and displaced, so that the bypass port 108 is connected with the annular cavity 102, so that the toothed plate 83 drives the gear 84 to rotate in the opposite direction to reset. During the resetting process, the stop rod 113 is staggered with the fixed push plate 12, and the spring 112 pushes the sealing block 111 to seal the connecting hole 106. At the same time, the air pump 72 is started, and the air pump 72 passes the gas into the annular cavity 102 through the through hole 73. At this time, the annular cavity 102 is sealed again and the internal air pressure increases rapidly. The air pressure acts on the clamping head 104, stretching the spring 105 while squeezing the outer ring of the bearing in the clamping positioning ring 101. As the outer ring of the bearing is driven to swing to the vertical upper side, the lead screw moving mechanism 2 on both sides drives the chamfering processing mechanism 3 to act synchronously to perform chamfering processing from both sides of the outer ring of the bearing;After the processing of the first bearing outer ring is completed, the No. 1 electric push rod 82 drives the tooth plate 83 to move horizontally, and cooperates with the gear 84 to make the support plate 71 rotate to the horizontal again and be located between the loading frame 131 and the reserved frame 132, and gradually keep the swing level when the fixed push plate 12 is pressed against the blocking rod 113 in the opening and closing assembly 11, pushing the sealing block 111 to move and compress the spring three 133 and open the connecting hole 106, so that the gas fed passes through the connecting hole 106 and is discharged from the bypass port 108, and the ring The high pressure in the cavity 102 cannot be established, and the spring 105 elastically resets to cancel the clamping and fixing of the outer ring of the bearing in the positioning ring 101, and as the second electric push rod 135 pushes the outer ring of the bearing to move again, the outer ring of the bearing pushed out from the loading frame 131 gradually pushes the outer ring of the bearing that has been clamped in the positioning ring 101 to move horizontally, and the new outer ring of the bearing moves into the positioning ring 101. After processing, the outer ring of the bearing compresses the spring 3 133 and is located in the reserved frame 132. As the clamping assembly 10 is rotated upward and swung again, the opening and closing The spring 112 in the assembly 11 quickly resets and pushes the sealing block 111 to reseal the connecting hole 106. The continuously fed gas re-establishes a high-pressure environment in the annular cavity 102 to achieve the clamping and fixing of the new bearing outer ring. When the positioning ring 101 is completely moved to a vertical state and the subsequent chamfering is performed, as the blocking assembly 14 rotates and swings with the clamping assembly 10, the inner end of the arc-shaped baffle 141 that follows the upward rotation moves to between the feeding frame 131 and the reserved frame 132, and the arc The notch 144 on the baffle plate 141 moves to one side of the reserved frame 132, and the spring 3 133 is elastically reset and pushes the processed bearing outer ring in the reserved frame 132 into the notch 144 and drops into the arc cavity 5, and it automatically falls out from the blanking port 9 along the arc cavity 5. When the bearing outer ring needs to be added later, it can be put in along the loading port 134. The limit stopper 136 automatically fills the bearing outer ring into the loading frame 131 under the reciprocating action, realizing continuous and rapid automatic loading and positioning. ;

[0039] Firstly, the swing control of the swing support assembly 7 is realized by utilizing the deflection assembly 8. When the swing support assembly 7 and the clamping assembly 10 are located vertically above, the chamfering processing mechanisms 3 on both sides are cooperated to complete the double-sided chamfering. When it swings to a horizontal state, the outer ring of the bearing is automatically pushed to the clamping assembly 10 through the position control of the quick switching assembly 13. As the clamping assembly 10 cooperates with the gas continuously output in the swing support assembly 7, after the clamping assembly 10 swings and staggers with the fixed push plate 12, the clamping head 104 re-clamps the outer ring of the bearing in the positioning ring 101 under the action of air pressure, and the loading and automatic clamping of the bearing are quickly completed. At the same time, the reserved frame 132 and the spring three 133 are utilized to After the clamping assembly 10 swings upward, the arc-shaped baffle 141 rotates accordingly, which, on the one hand, realizes sealing on one side of the loading frame 131 to prevent the bearing in the loading frame 131 from falling out, and on the other hand, utilizes the notch 144 on the other side of the arc-shaped baffle 141 to realize the automatic pushing out and dropping of the processed bearing outer ring in the reserved frame 132, so as to realize the chamfering processing of large quantities of bearing outer rings, realize continuous and rapid loading, and automatically complete the positioning and clamping of the bearing outer ring after loading, and realize automatic withdrawal of the bearing outer ring after processing during continuous loading, and the entire continuous processing production efficiency is extremely high, loading, positioning, clamping, and double-sided chamfering are realized continuously and quickly, and unloading is completed at the same time as loading, reducing intermediate operations and greatly improving production and processing efficiency.

When the clamping component 10 rotates horizontally for loading and unloading, the blocking component 14 rotates accordingly, and at this time the sealing arc block 142 slides and rotates upward along the inside of the arc cavity 5 toward the upper end, pushing out the granular debris collected in the arc cavity 5 for unified collection and processing.

[0041] First, by utilizing the swinging action of the clamping assembly 10 again, when the chamfering is started by swinging up to the vertical state, the sealing arc block 142 in the blocking assembly 14 is ensured to open the local space of the arc cavity 5, and the vacuum pump 15 is used to suck the debris generated by the chamfering and concentrate it into the arc cavity 5. When the clamping assembly 10 is rotated to the horizontal state for loading and unloading, the sealing arc block 142 is driven to rotate upward and slide along the inside of the arc cavity 5, and the collected debris is uniformly pushed to the top of the processing table 1, and the collected debris can be directly recycled and processed in a unified manner, avoiding the need for complex and large-scale cleaning operations for scattered debris and impurities, greatly reducing the difficulty of subsequent cleaning and recycling, and having a good use effect.

[0045] The deflection assembly 8 realizes the rotation and swing of a group of support shafts 6 through the meshing of the tooth plate 83 and the gear 84, thereby driving the rotation and swing of the swing support assembly 7. One end of the support seat 4 is closed to achieve precise control of the swing angle, which is achieved by the limit effect.

[0049] The clamping assembly 10 uses the air pressure in the internal annular cavity 102 to push the clamping head 104 to slide out, thereby clamping and fixing the outer ring of the bearing in the positioning ring 101.

The reserved frame 132 first stores the processed bearing outer ring, and when there is enough space on the front, it is automatically pushed out by spring three 133 to complete automatic unloading. The limit stopper 136 ensures that the loading port 134 is blocked during the lateral movement to prevent the workpiece in the loading barrel from falling to the other side of the loading frame 131.

[0052] Among them, the blocking assembly 14 includes an arc baffle 141, a sealing arc block 142, an intermediate plate 143 and a notch 144. One end of the arc baffle 141 is fixedly connected to the outer surface of the clamping assembly 10, the sealing arc block 142 is slidably sleeved inside the arc cavity 5, the intermediate plate 143 is fixedly connected between the arc baffle 141 and the sealing arc block 142, the notch 144 is opened on the side of the inner end of the arc baffle 141, and the notch 144 is located on a side of the arc baffle 141 close to the reserved frame 132. The vacuum pump 15 is sleeved in the processing table 1 through the suction pipeline and is connected to the arc cavity 5. The suction port of the vacuum pump 15 is located on the side away from the blanking port 9.

[0053] The blocking component 14 rotates in the arc cavity 5 following the swing of the clamping component 10, and uses the arc baffle 141 to limit and block the loading frame 131 to prevent the loading frame 131 from falling when the loading frame 131 is swung in a vertical state for processing. At the same time, by using the notch 144, when in the vertical processing position, while maintaining the blocking of one side of the loading frame 131, the reserved frame 132 on the other side is allowed to elastically push the processed workpiece stored inside to the notch 144 and drop it, thereby cooperating with the arc cavity 5 and the blanking port 9 to complete automatic discharge collection, and the sealing arc block 142 adapts to the internal cross-sectional size of the arc cavity 5. It is ensured that the dynamic seal is maintained in the arc cavity 5, and the outer surface of the sealing arc block 142 can be provided with an elastic sealing pad to further provide a dynamic sealing effect. During the swinging process, the sealing arc block 142 opens the suction port of the vacuum pump 15 when rotating downward, allowing the processing debris particles to be sucked into the arc cavity 5, and actively pushes out the collected debris particles when rotating upward, thereby improving the convenience of collection and processing. The suction port of the suction pipe of the vacuum pump 15 is provided with a filter cloth to improve the filtering effect, and the sealing arc block 142 that slides up and down repeatedly actively hangs the filter cloth at the suction pipe of the vacuum pump 15 to avoid blockage.

[0054] A processing method of a chamfering device for processing an internal bearing of an air circuit breaker, comprising the following processing steps:

[0055] Step 1: During continuous operation, as the clamping assembly 10 in the vertical state cooperates with the chamfering processing mechanism 3 on both sides to process the outer ring of the bearing, the deflection assembly 8 drives the swing support assembly 7 to rotate to a horizontal state, so that the clamping assembly 10 is located between the loading frame 131 and the reserved frame 132 of the quick switching assembly 13, and the opening and closing assembly 11 is squeezed and contacted with the fixed push plate 12 during movement, bypassing the internal pressure air of the clamping assembly 10, canceling the clamping fixation of the outer ring of the bearing, and at the same time, the quick switching assembly 13 pushes the bearing to be processed into the clamping assembly 10, and automatically pushes the processed outer ring of the bearing To the reserved frame 132, the deflection assembly 8 is started and the clamping assembly 10 is driven to reset to the vertical state. When the clamping assembly 10 is away from the fixed push plate 12, the opening and closing assembly 11 is re-closed, the internal pressure of the clamping assembly 10 is restored and the outer ring of the bearing is clamped, and the clamping assembly 10 is swung back to the vertical state. At this time, the arc baffle 141 in the blocking assembly 14 swings into the fast switching assembly 13, and the notch 144 is aligned with the reserved frame 132. The outer ring of the bearing processed in the reserved frame 132 is elastically pushed to the notch 144 and falls into the arc cavity 5, and falls out along the blanking port 9, completing the switching and discharging;

[0056] Step 2: After resetting to vertical, the chamfering processing mechanisms 3 on both sides are brought close to each other and chamfering is performed;

[0057] Step 3: At the same time, the vacuum pump 15 is started, and the vacuum pump 15 sucks the dust particles in the processing process into the arc cavity 5;

[0058] Step 4: After the processing is completed, the clamping assembly 10 is swung to a horizontal state again to quickly load and unload materials. At the same time, the blocking assembly 14 pushes the impurities collected in the arc cavity 5 upward along the arc cavity 5 to complete the unified collection and cleaning, and wait for the next swing-up reset processing.

[0059] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
