Description
Technical Field
[0001] The invention relates to the technical field of clamp equipment, and in particular to a nut processing clamp and a use method thereof. Background Art
[0002] Bolt fixing, welding fixing and buckle fixing are common fixing methods in mechanical structures. Bolt fixing and buckle fixing both have the advantage of easy disassembly, but bolt fixing has better tightness and safety.
[0003] Welding fixation is often used for the connection and fixation of closed structures, but after bolt fixation is combined with sealing strips, it can also be used for the fixation of closed structures.
[0004] Among them, when processing hexagonal nuts, the hexagonal shape is often processed first, and then the internal thread is processed. The nuts are usually processed in batches with a fast production speed. When the nuts are frequently placed for processing, the hexagonal shape of the nuts may not match the clamp when they are placed, resulting in clamp marks or damage to the nuts when clamped, affecting the use of the nuts. Summary of the invention
[0005] In order to solve the above technical problems, the present invention provides a nut processing fixture, including a correction mechanism, the correction mechanism also includes a base, the top of the base is fixedly connected with a fixed plate, and the inner wall of the fixed plate is slidably connected with a plurality of clamping blocks;
[0006] The extrusion mechanism includes a connecting plate 1 fixedly connected to a side wall of the front clamping block, a sliding groove is provided on the side wall of the connecting plate 1, a connecting tube 2 is provided on the top of the fixed plate, and a plurality of connecting plates 2 are fixedly connected to the outer wall of the connecting tube 2;
[0007] The flipping mechanism includes a rack slidably connected to the bottom of the connecting plate 2 located on the left side, a connecting sleeve 1 is fixedly connected to the bottom of the connecting plate 2 located on the left side, and a spring reset rod 1 is slidably connected to the inner wall of the connecting sleeve 1.
[0008] Preferably, the correction mechanism also includes a motor fixedly connected to the bottom of the base, and the top output end of the motor is fixedly connected to a rotating disk, and a plurality of arc-shaped grooves 1 are opened on the top of the rotating disk, and a rotating frame is slidably connected to the inner walls of the plurality of arc-shaped grooves 1, and the tops of the rotating frames located on the front and back sides are rotatably connected to the bottom of the clamping block 1, and the tops of the rotating frames located on the left and right sides are rotatably connected to the clamping block 2. When the hexagonal nut is clamped by the clamping block 2 and the clamping block 1, the nut can be corrected. The nut is placed on the top of the support block, and then the motor is started to drive the rotating disk to rotate. When the rotating disk rotates, the arc-shaped groove 1 will push the rotating frame to move, thereby driving the clamping block 1 and the clamping block 2 to move close to the nut at the same time.
[0009] Preferably, the correction mechanism also includes a fixed plate fixedly connected to the side wall of the clamping block two, the top of the rotating disk is rotatably connected to a connecting tube one, the inner wall of the connecting tube one is rotatably connected to a supporting block, the inner walls of several fixed plates are fixedly connected to spring telescopic rods, the side walls of several spring telescopic rods are fixedly connected to extrusion plates, the inner walls of several clamping blocks two are slidably connected to correction plates, and the top of the base is slidably connected to a collecting box. When the clamping block two moves, it will drive the extrusion plate and the correction plate to approach the nut, and the extrusion plates on both sides will first contact the nut to squeeze the nut, and the extrusion plate will be subjected to a reaction force to squeeze the spring telescopic rod, allowing the spring telescopic rod to accumulate rebound force, and relying on the rebound force of the spring telescopic rod to pre-press the nut. If the straight edge of the nut is not parallel to the extrusion plate, it means that the contact area between the extrusion plate and the nut is small. At this time, the clamping force on the nut is small. After the extrusion plate and the nut are in contact, the correction plate will also contact the nut, allowing The correction plates on both sides push the two sides of the nut, allowing the nut to rotate slowly so that the straight edge of the nut fits with the extrusion plate. After fitting, due to the strong resilience accumulated in the spring telescopic rod and the fit of the extrusion plate and the nut, the nut is subjected to a large extrusion force, so the correction plate will not push the nut to rotate, and at this time the contact surface between the nut and the correction plate is an inclined surface, and the correction plate will be affected by the inclined surface to move and gradually separate from the nut until the extrusion plate and the fixed plate fit together to clamp the nut, and at this time the beveled edge of the correction plate will also be aligned with the sharp corner of the nut, and the clamping block 1 will push the correction plate to clamp the nut, and the contact area between the clamping block 1 and the nut is increased through the correction plate, thereby making the clamping effect more stable, and correcting before clamping the nut can avoid frequent clamping during batch processing of the nut, resulting in the situation where the nut is not placed in place, resulting in a smaller contact area with the outer wall of the nut when the fixture is clamped, resulting in concentrated extrusion force, which may cause deformation or damage to the nut.
[0010] Preferably, the extrusion mechanism also includes a spring extrusion ring fixedly connected to the bottom of the connecting tube two, and a plurality of fixed rods one are fixedly connected to the top of the fixed plate, and the outer walls of the plurality of fixed rods one are slidably connected to the inner wall of the connecting plate two. The force of the movement of the clamping block one is used to drive the connecting plate one to move. When the connecting plate one moves, the connecting rod at the side wall of the connecting tube two will slide in the sliding groove. After the connecting plate one moves a certain distance, the connecting rod will descend at the inclined surface of the sliding groove, causing the connecting tube two to descend, driving the connecting plate two to descend horizontally under the limit of the fixed rod one, allowing the spring extrusion ring to descend close to the nut, so that the spring extrusion ring squeezes the nut, and first contacts the inclined end of the nut to move the nut.
[0011] Preferably, the flip mechanism also includes a connecting rod fixedly connected to the side wall of the supporting block, the side wall of the connecting rod is fixedly connected with a gear, the outer wall of the gear is meshed with the side wall of the rack, the outer wall of the connecting tube is fixedly connected with a plurality of connecting sleeves 2, the inner walls of the plurality of connecting sleeves 2 are slidably connected with spring return rods 2, the side wall of the spring return rod 1 is fixedly connected with the side wall of the rack, and the rack is driven to descend by the force of the connecting plate 2 descending. When the rack and the gear contact, a nut is placed on the top of the supporting block and the nut is pre-pressed by the extrusion plate, so that the rack will not drive the gear to rotate. Since the gear will not rotate at this time, but the rack can slide, when the rack continues to move, the gear will squeeze the rack to separate the rack from the gear. When the rack moves, it will drive the spring return rod 1 to move, allowing the spring return rod 1 to accumulate rebound force, thereby allowing the connecting plate 2 to descend. When the rack is separated from the gear, the rack is returned to its position by the rebound force of the spring return rod 1, and when the nut is processed.
[0012] Preferably, the flipping mechanism also includes a plurality of arc-shaped scrapers arranged at the bottom of the support block, the side walls of the plurality of arc-shaped scrapers are fixedly connected to the side walls of the spring return rod 2, the top of the fixed plate is provided with a plurality of arc-shaped grooves 2, the outer wall of the connecting tube 1 is provided with a plurality of movable grooves, the interior of the connecting tube 1 is provided with a plurality of connecting frames, the outer walls of the plurality of connecting frames are slidably connected to the inner walls of the movable grooves, after the clamping block 1 and the clamping block 2 are separated from the nut and the nut is removed, the clamping block 1 is continued to be moved to make the connecting tube 2 rise, at this time, the rack and the gear are in contact, which will drive the gear to rotate, so that the connecting rod rotates, so that the support The support block flips and the debris generated by processing the nut falls into the connecting tube one. When the connecting tube one flips, it will also fit with the arc surface of the spring return rod two, squeezing the side wall of the arc scraper, allowing the arc scraper to squeeze the spring return rod two. When the support block is flipped, the rebound force of the spring return rod two is released, allowing the arc scraper to move quickly to clean the debris stuck to the bottom of the support block, and drop it into the collection box through the arc groove two. By keeping the support block clean, it is avoided that debris remains on the support block, which causes the nut to tilt easily when placed. Keeping the nut level also avoids large debris that causes the spring extrusion ring to be unable to flatten the nut.
[0013] Preferably, the flipping mechanism also includes a return spring fixedly connected to the bottom of the connecting frame, a plurality of pushing frames are arranged inside the connecting tube one, a plurality of fixed rods two are fixedly connected to the inner wall of the connecting tube one, the inner walls of the plurality of pushing frames are rotatably connected to the outer wall of the fixed rod two, the inner walls of the plurality of pushing frames are slidably connected to the moving rods, and the side walls of the plurality of moving rods are fixedly connected to the arc plates. By utilizing the force of the flipping of the support block, when the support block flips, it will touch the connecting frame, allowing the connecting frame to slide and descend in the moving groove, and at the same time squeeze the return spring to allow the return spring to accumulate rebound force. When the connecting frame descends, it will slide inside the pushing frame, pushing the pushing frame to move, allowing the pushing frame to rotate, so that the bottom of the pushing frame slides at the outer wall of the moving rod, pushing the moving rod to move, thereby allowing the arc plate to move, and pushing the debris that falls around the connecting tube one into the arc groove two, and by cleaning the debris around the connecting tube one, it is possible to prevent the accumulation of debris, which may affect the movement of the clamping block one and the clamping block two when they move around the connecting tube one.
[0014] A method for using a nut processing fixture includes the following steps:
[0015] S1: Place the nut on the top of the support block, then start the motor to drive the rotating disk to rotate. When the rotating disk rotates, the arc groove 1 pushes the rotating frame to move, thereby driving the clamping block 1 and the clamping block 2 to move close to the nut at the same time;
[0016] S2: When the clamping block 2 moves, it will drive the extrusion plate and the correction plate close to the nut. The extrusion plates on both sides will first contact the nut and squeeze the nut, while the extrusion plates will be subjected to the reaction force and squeeze the spring telescopic rod;
[0017] S3: Let the spring telescopic rod accumulate rebound force, and rely on the rebound force of the spring telescopic rod to pre-press the nut. After the extrusion plate contacts the nut, the correction plate will also contact the nut. Let the correction plates on both sides push the two sides of the nut, and let the nut rotate slowly so that the straight edge of the nut fits with the extrusion plate.
[0018] The present invention has the following beneficial effects:
[0019] (1) The present invention utilizes the characteristic that when the clamping block 2 and the clamping block 1 clamp the hexagonal nut, the nut can be corrected. The nut is placed on the top of the support block, and then the motor is started to drive the rotating disk to rotate. When the rotating disk rotates, the arc groove 1 will push the rotating frame to move, thereby driving the clamping block 1 and the clamping block 2 to move close to the nut at the same time. When the clamping block 2 moves, it will drive the extrusion plate and the correction plate to approach the nut. The extrusion plates on both sides will first contact the nut and squeeze the nut. The extrusion plates will be subjected to a reaction force and squeeze the spring telescopic rod, allowing the spring telescopic rod to accumulate rebound force. The nut is pre-pressed by the rebound force of the spring telescopic rod. If the straight edge of the nut is not parallel to the extrusion plate, it means that the contact area between the extrusion plate and the nut is small. At this time, the clamping force on the nut is small. After the extrusion plate and the nut are in contact, the correction plate will also contact the nut, allowing the correction plates on both sides to push the two sides of the nut, allowing the nut to rotate slowly, so that the nut The straight edge of the nut fits with the extrusion plate. After fitting, due to the strong resilience accumulated in the spring telescopic rod and the fit of the extrusion plate and the nut, the nut is subjected to a large extrusion force, so the correction plate will not push the nut to rotate, and at this time the contact surface between the nut and the correction plate is an inclined surface, the correction plate will be affected by the inclined surface and move gradually separated from the nut until the extrusion plate and the fixed plate fit together to clamp the nut, and at this time the beveled edge of the correction plate will also be aligned with the sharp corner of the nut, and the clamping block 1 will push the correction plate to clamp the nut, and the contact area between the clamping block 1 and the nut will be increased through the correction plate, thereby making the clamping effect more stable, and correcting before clamping the nut can avoid frequent clamping during batch processing of the nut, resulting in the situation of improper placement, resulting in a smaller contact area with the outer wall of the nut when the fixture is clamped, resulting in concentrated extrusion force, which may cause deformation or damage to the nut, ensuring that the nut can be correctly aligned and fixed.
[0020] (2) The present invention utilizes the force of the movement of the clamping block 1 to drive the connection plate 1 to move. When the connection plate 1 moves, it will cause the connecting rod at the side wall of the connection tube 2 to slide in the sliding groove. After the connection plate 1 moves a certain distance, the connecting rod will descend at the inclined surface of the sliding groove, causing the connection tube 2 to descend, driving the connection plate 2 to descend horizontally under the limit of the fixed rod 1, allowing the spring extrusion ring to descend close to the nut, so that the spring extrusion ring squeezes the nut and contacts the inclined end of the nut first, allowing the nut to move. At this time, the extrusion plate will pre-press the nut, but the clamping force is small. The spring extrusion ring can smoothly push the nut to move. If the nut is not tilted, it can also ensure that the nut fits the top of the support block, avoiding the debris during processing causing the nut to tilt during placement, so that when the correction plate pushes the nut to rotate, the nut may be misplaced, increasing the difficulty of positioning during processing and affecting the accuracy of positioning.
[0021] (3) The present invention utilizes the force of the second connecting plate descending to drive the rack to descend. When the rack and the gear are in contact, since a nut is placed on the top of the support block and the nut is pre-pressed by the extrusion plate, the rack will not drive the gear to rotate. Since the gear will not rotate at this time, but the rack can slide, when the rack continues to move, the gear will squeeze the rack, causing the rack to separate from the gear. When the rack moves, it will drive the spring return rod 1 to move, allowing the spring return rod 1 to accumulate rebound force, thereby causing the second connecting plate to descend. When the rack is separated from the gear, the rack is returned to its original position by the rebound force of the spring return rod 1. When the nut is processed, the clamping block 1 and the second clamping block are separated from the nut. After the nut is removed, the clamping block 1 is continued to move to allow the second connecting tube to move upward. When the support block is flipped, the rack and the gear are in contact, which will drive the gear to rotate, allowing the connecting rod to rotate, causing the support block to flip and the debris generated by the processing of the nut to fall into the connecting tube one. When the connecting tube one flips, it will also fit the arc surface of the spring reset rod two, squeezing the side wall of the arc scraper, allowing the arc scraper to squeeze the spring reset rod two. When the support block is flipped, the rebound force of the spring reset rod two is released, allowing the arc scraper to move quickly to clean the debris stuck to the bottom of the support block, and drop it into the collection box through the arc groove two. By keeping the support block clean, it is avoided that debris remains on the support block, which causes the nut to tilt easily when placed, keeps the nut level, and also avoids large debris that causes the spring extrusion ring to be unable to flatten the nut.
[0022] (4) The present invention utilizes the force of the support block flipping. When the support block flips, it touches the connecting frame, causing the connecting frame to slide down in the moving groove and squeeze the reset spring at the same time, allowing the reset spring to accumulate rebound force. When the connecting frame descends, it slides inside the pushing frame, pushing the pushing frame to move, causing the pushing frame to rotate, thereby allowing the bottom of the pushing frame to slide on the outer wall of the moving rod, pushing the moving rod to move, thereby allowing the arc plate to move, pushing the debris that falls around the connecting tube one into the arc groove two, and then falling into the collection box through the arc groove two. When the support block is horizontal, the rebound force of the spring telescopic rod allows the connecting frame to reset, thereby allowing the arc plate to return to its position, and by cleaning the debris around the connecting tube one, it is avoided that the debris accumulates and the clamping block one and the clamping block two are affected by the accumulated debris when they move around the connecting tube one.

DETAILED DESCRIPTION
[0035] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.
[0036] For example, see Figure 1 - Figure 3 The present invention is a nut processing fixture, including a correction mechanism 1, the correction mechanism 1 also includes a base 101, the top of the base 101 is fixedly connected with a fixed plate 102, and the inner wall of the fixed plate 102 is slidably connected with a plurality of clamping blocks 103;
[0037] The extrusion mechanism 2 includes a connecting plate 201 fixedly connected to the side wall of the front clamping block 103, a sliding groove 202 is provided on the side wall of the connecting plate 201, a connecting tube 203 is provided on the top of the fixed plate 102, and a plurality of connecting plates 204 are fixedly connected to the outer wall of the connecting tube 203;
[0038] The flipping mechanism 3 includes a rack 301 slidably connected to the bottom of the connecting plate 204 on the left side, a connecting sleeve 1 302 is fixedly connected to the bottom of the connecting plate 204 on the left side, and a spring return rod 1 303 is slidably connected to the inner wall of the connecting sleeve 1 302.
[0039] The correction mechanism 1 also includes a motor 104 fixedly connected to the bottom of the base 101, and a rotating disk 105 is fixedly connected to the top output end of the motor 104. A plurality of arc-shaped grooves 106 are provided on the top of the rotating disk 105, and a rotating frame 107 is slidably connected to the inner walls of the plurality of arc-shaped grooves 106. The tops of the rotating frames 107 located on the front and back sides are rotatably connected to the bottom of the clamping block 103, and the tops of the rotating frames 107 located on the left and right sides are rotatably connected to the clamping block 2 108. When the clamping block 2 108 and the clamping block 1 103 clamp the hexagonal nut, the nut can be corrected. The nut is placed on the top of the support block 110, and then the motor 104 is started to drive the rotating disk 105 to rotate. When the rotating disk 105 rotates, the arc-shaped groove 106 pushes the rotating frame 107 to move, thereby driving the clamping block 103 and the clamping block 2 108 to move close to the nut at the same time.
[0040] The correction mechanism 1 also includes a fixed plate 111 fixedly connected to the side wall of the clamping block 108, the top of the rotating disk 105 is rotatably connected to the connecting tube 109, the inner wall of the connecting tube 109 is rotatably connected to the supporting block 110, the inner walls of several fixed plates 111 are fixedly connected to spring telescopic rods 112, the side walls of several spring telescopic rods 112 are fixedly connected to extrusion plates 113, the inner walls of several clamping blocks 108 are slidably connected to correction plates 114, and the top of the base 101 is slidably connected to a collecting box 115. When the clamping block 108 moves, it will drive the extrusion plate 113 and the correction plate 114 close to the nut. The extrusion plates 113 on both sides will first contact the nut and squeeze the nut. The extrusion plate 113 will be subjected to a reaction force and squeeze the spring telescopic rod 112, allowing the spring telescopic rod 112 to accumulate rebound force. The nut is pre-pressed by the rebound force of the spring telescopic rod 112. If the straight edge of the nut is not parallel to the extrusion plate 113, it means that the contact area between the extrusion plate 113 and the nut is small. At this time, the clamping force on the nut is small, and the extrusion plate 113 and the nut are in contact. After that, the correction plate 114 will also contact the nut, allowing the correction plates 114 on both sides to push the two sides of the nut, allowing the nut to slowly rotate, so that the straight edge of the nut fits with the extrusion plate 113. After fitting, since the resilience accumulated by the spring telescopic rod 112 is strong and the extrusion plate 113 fits with the nut, the extrusion force on the nut is large, so the correction plate 114 will not push the nut to rotate. At this time, the contact surface between the nut and the correction plate 114 is an inclined surface, and the correction plate 114 will be affected by the inclined surface to move and gradually separate from the nut until the extrusion plate 113 and the fixing plate 113 are aligned. 1 fits and clamps the nut, and the beveled edge of the correction plate 114 will be aligned with the sharp corner of the nut at this time, and the clamping block 103 will push the correction plate 114 to clamp the nut. The contact area between the clamping block 103 and the nut is increased through the correction plate 114, so that the clamping effect is more stable. By correcting the nut before clamping it, frequent clamping during batch processing of the nut can be avoided, resulting in the situation of improper placement, which will reduce the contact area with the outer wall of the nut when the fixture is clamped, resulting in concentrated extrusion force, which may cause deformation or damage to the nut.
[0041] For example 2, please refer to Figure 4 - Fig. 9The present invention is a nut processing fixture. On the basis of embodiment 1, the extrusion mechanism 2 also includes a spring extrusion ring 205 fixedly connected to the bottom of the connecting tube 203. The top of the fixed disk 102 is fixedly connected with a plurality of fixed rods 206. The outer walls of the plurality of fixed rods 206 are slidably connected to the inner wall of the connecting plate 204. The force of the movement of the clamping block 103 is used to drive the connecting plate 101 to move. When the connecting plate 101 moves, the connecting rod at the side wall of the connecting tube 203 will slide in the sliding groove 202. After the connecting plate 101 moves a certain distance, the connecting rod will drop at the inclined surface of the sliding groove 202, causing the connecting tube 203 to drop, driving the connecting plate 204 to drop horizontally under the limit of the fixed rod 106, allowing the spring extrusion ring 205 to drop close to the nut, so that the spring extrusion ring 205 squeezes the nut and contacts the inclined end of the nut first, allowing the nut to move.
[0042] The flip mechanism 3 also includes a connecting rod 305 fixedly connected to the side wall of the support block 110, a gear 304 is fixedly connected to the side wall of the connecting rod 305, the outer wall of the gear 304 is meshed with the side wall of the rack 301, a plurality of connecting sleeves 2 306 are fixedly connected to the outer wall of the connecting cylinder 109, and a plurality of spring return rods 2 307 are slidably connected to the inner walls of the plurality of connecting sleeves 2 306, the side wall of the spring return rod 1 303 is fixedly connected to the side wall of the rack 301, and the rack 301 is driven to descend by the downward force of the connecting plate 204. When the rack 301 and the gear 304 are in contact, due to the support block 110 A nut is placed on the top and the nut is pre-pressed by the extrusion plate 113, so the rack 301 will not drive the gear 304 to rotate. Since the gear 304 will not rotate at this time, and the rack 301 can slide, when the rack 301 continues to move, the gear 304 will squeeze the rack 301, so that the rack 301 and the gear 304 are separated. When the rack 301 moves, it will drive the spring return rod 1 303 to move, so that the spring return rod 1 303 accumulates rebound force, thereby allowing the connecting plate 204 to descend. When the rack 301 is separated from the gear 304, the rack 301 is returned to its original position through the rebound force of the spring return rod 1 303, and the nut is processed.
[0043] The flip mechanism 3 also includes a plurality of arc scrapers 308 arranged at the bottom of the support block 110, and the side walls of the plurality of arc scrapers 308 are fixedly connected to the side walls of the spring return rod 2 307. The top of the fixed disk 102 is provided with a plurality of arc grooves 2 309, and the outer wall of the connecting tube 109 is provided with a plurality of movable grooves 311. The interior of the connecting tube 109 is provided with a plurality of connecting frames 310, and the outer walls of the plurality of connecting frames 310 are slidably connected to the inner walls of the movable grooves 311. After the clamping block 103 and the clamping block 2 108 are separated from the nut and the nut is removed, the clamping block 103 is continued to be moved to make the connecting tube 2 203 rise. At this time, the rack 301 is in contact with the gear 304, which will drive the gear 304 to rotate, so that the connecting rod 305 rotates. The support block 110 is moved, causing the support block 110 to flip over and the debris generated by processing the nut falls into the connecting tube 109. When the connecting tube 109 flips over, it will also fit with the arc surface of the spring return rod 2 307, squeezing the side wall of the arc scraper 308, allowing the arc scraper 308 to squeeze the spring return rod 2 307. When the support block 110 is flipped over, the rebound force of the spring return rod 2 307 is released, allowing the arc scraper 308 to move quickly to clean the debris adhered to the bottom of the support block 110, and drop it into the collection box 115 through the arc groove 2 309. By keeping the support block 110 clean, it is avoided that debris remains on the support block 110, which causes the nut to tilt easily when placed, keeps the nut level, and also avoids large debris that causes the spring extrusion ring 205 to be unable to flatten the nut.
[0044] The flipping mechanism 3 also includes a return spring 312 fixedly connected to the bottom of the connecting frame 310, a plurality of pushing frames 314 are arranged inside the connecting tube 109, a plurality of fixing rods 313 are fixedly connected to the inner wall of the connecting tube 109, the inner walls of the plurality of pushing frames 314 are rotatably connected to the outer wall of the fixing rod 2 313, the inner walls of the plurality of pushing frames 314 are slidably connected to the moving rods 315, the side walls of the plurality of moving rods 315 are fixedly connected to the arc plates 316, and the flipping force of the support block 110 is utilized, when the support block 110 flips, it will touch the connecting frame 310, so that the connecting frame 310 slides down in the moving groove 311, and at the same time When the connecting frame 310 is lowered, the reset spring 312 is squeezed to allow the reset spring 312 to accumulate a rebound force. When the connecting frame 310 descends, it will slide inside the pushing frame 314, pushing the pushing frame 314 to move and allowing the pushing frame 314 to rotate, so that the bottom of the pushing frame 314 slides on the outer wall of the moving rod 315, pushing the moving rod 315 to move, thereby allowing the arc plate 316 to move and push the debris that has fallen around the connecting cylinder 109 into the arc groove 2 309. By cleaning the debris around the connecting cylinder 109, it is avoided that the accumulation of debris causes the clamping block 103 and the clamping block 2 108 to be affected by the accumulated debris when moving around the connecting cylinder 109.
[0045] The method for using the nut processing fixture includes the following steps:
[0046] S1: Place the nut on the top of the support block 110, then start the motor 104 to drive the rotating disk 105 to rotate. When the rotating disk 105 rotates, the arc groove 106 pushes the rotating frame 107 to move, thereby driving the clamping block 103 and the clamping block 2 108 to move close to the nut at the same time;
[0047] S2: When the second clamping block 108 moves, it will drive the extrusion plate 113 and the correction plate 114 close to the nut. The extrusion plates 113 on both sides will first contact the nut and squeeze the nut, while the extrusion plates 113 will be subjected to a reaction force and squeeze the spring telescopic rod 112;
[0048] S3: Allow the spring telescopic rod 112 to accumulate resilience, and rely on the resilience of the spring telescopic rod 112 to pre-press the nut. After the extrusion plate 113 contacts the nut, the correction plate 114 will also contact the nut, allowing the correction plates 114 on both sides to push both sides of the nut, allowing the nut to rotate slowly, so that the straight edge of the nut fits with the extrusion plate 113.
[0049] A specific application of this embodiment is: when the present invention is used, the hexagonal nut can be corrected by using the clamping block 2 108 and the clamping block 1 103. The nut is placed on the top of the support block 110, and then the motor 104 is started to drive the rotating disk 105 to rotate. When the rotating disk 105 rotates, the arc groove 106 pushes the rotating frame 107 to move, thereby driving the clamping block 103 and the clamping block 2 108 to move close to the nut at the same time. When the clamping block 2 108 moves, it drives the extrusion plate 113 and the correction plate When the nut 114 is close to the nut, the extrusion plates 113 on both sides will first contact the nut and squeeze the nut, and the extrusion plate 113 will be subjected to the reaction force to squeeze the spring telescopic rod 112, so that the spring telescopic rod 112 accumulates the rebound force, and the nut is pre-pressed by the rebound force of the spring telescopic rod 112. If the straight edge of the nut is not parallel to the extrusion plate 113, it means that the contact area between the extrusion plate 113 and the nut is small, and the clamping force on the nut is small at this time. After the extrusion plate 113 contacts the nut, the correction plate 114 will also contact the nut, so that the correction plates on both sides The plate 114 pushes both sides of the nut, allowing the nut to rotate slowly, so that the straight edge of the nut fits with the extrusion plate 113. After fitting, since the spring telescopic rod 112 has a strong resilience, and the extrusion plate 113 fits with the nut, the nut is subjected to a large extrusion force, so the correction plate 114 will not push the nut to rotate. At this time, the contact surface between the nut and the correction plate 114 is an inclined surface, and the correction plate 114 will be affected by the inclined surface to move and gradually separate from the nut, until the extrusion plate 113 fits with the fixing plate 111 to clamp the nut, and at this time, the correction plate The beveled edge of 114 will also be aligned with the sharp corner of the nut, and the clamping block 103 will push the correction plate 114 to clamp the nut. The correction plate 114 increases the contact area between the clamping block 103 and the nut, so that the clamping effect is more stable. By correcting the nut before clamping it, it is avoided that the nuts are frequently clamped during batch processing, and the nuts are not placed in place, resulting in a smaller contact area with the outer wall of the nut when the clamp is clamped, resulting in concentrated extrusion force, which may cause deformation or damage to the nut, and ensure that the nut can be correctly aligned and fixed;
[0050] The force of the clamping block 103 moving is used to drive the connecting plate 1 201 to move. When the connecting plate 1 201 moves, the connecting rod at the side wall of the connecting tube 203 will slide in the sliding groove 202. After the connecting plate 1 201 moves a certain distance, the connecting rod will drop at the inclined surface of the sliding groove 202, causing the connecting tube 203 to drop, driving the connecting plate 204 to drop horizontally under the limit of the fixed rod 1 206, allowing the spring extrusion ring 205 to drop close to the nut, so that the spring extrusion ring 205 squeezes the nut and contacts the inclined end of the nut first, allowing the nut to move. At this time, the extrusion plate 113 will pre-press the nut, but the pressing force is small, and the spring extrusion ring 205 can smoothly push the nut to move. 304 is pressed against the top of the support block 110, and the gear 304 is pressed against the top of the support block 110. The gear 304 does not rotate at this time, and the rack 301 can slide. When the rack 301 continues to move, the gear 304 will squeeze the rack 301, and the gear 304 will be pressed against the top of the support block 110. 1, the rack 301 is separated from the gear 304. When the rack 301 moves, it will drive the spring return rod 1 303 to move, so that the spring return rod 1 303 accumulates the rebound force, so that the connecting plate 204 drops. When the rack 301 is separated from the gear 304, the rack 301 is returned to its original position by the rebound force of the spring return rod 1 303. When the nut is processed, the clamping block 103 and the clamping block 2 108 are separated from the nut, and the nut is removed. Then, the clamping block 103 is continued to be moved to make the connecting tube 2 203 rise. At this time, the rack 301 and the gear 304 are in contact, which will drive the gear 304 to rotate, so that the connecting rod 305 rotates, and the support block 110 is turned over to drop the debris generated by the processing of the nut. When the support block 110 is turned over, the rebound force of the spring return rod 307 is released, so that the arc scraper 308 can quickly move to clean the debris adhered to the bottom of the support block 110, and the debris falls into the collection box 115 through the arc groove 309. By keeping the support block 110 clean, it is avoided that the debris remains on the support block 110, which causes the nut to tilt when placed, keeps the nut level, and also avoids large debris, which causes the spring extrusion ring 205 to be unable to flatten the nut.
[0051] By utilizing the force of the flipping of the support block 110, when the support block 110 flips, it will touch the connecting frame 310, so that the connecting frame 310 slides down in the moving groove 311, and at the same time, the reset spring 312 is squeezed to allow the reset spring 312 to accumulate resilience. When the connecting frame 310 descends, it will slide inside the pushing frame 314, pushing the pushing frame 314 to move, so that the pushing frame 314 rotates, so that the bottom of the pushing frame 314 slides on the outer wall of the moving rod 315, pushing the moving rod 315 to move, so that the arc The plate 316 moves to push the debris that has fallen around the connecting tube 109 into the arc groove 2 309, and then falls into the collection box 115 through the arc groove 2 309. When the support block 110 is horizontal, the connecting frame 310 is reset by the rebound force of the spring telescopic rod 112, thereby returning the arc plate 316 to its original position. By cleaning the debris around the connecting tube 109, it is avoided that the accumulation of debris may affect the movement of the clamping block 103 and the clamping block 2 108 when they move around the connecting tube 109.
