The outer wall of the power fittings needs to be polished during the processing. When polishing and cutting burrs on the top of the cylindrical fittings, traditional polishing equipment mostly fixes the fittings to be polished manually before sending them for polishing. Therefore, frequent manual clamping operations are required, which has a high labor intensity for workers and a low safety factor for operation, reducing the overall work efficiency. After polishing, the fittings are disassembled, and the back and forth operation is time-consuming and labor-intensive, which is very inconvenient. Moreover, the flying debris during polishing is easy to splash, causing pollution to the surrounding environment. In addition, some debris is attached to the polished parts, which is not convenient to remove and classify well, increasing the subsequent price steps and reducing production efficiency. At the same time, during the polishing process, the fittings are fixed and cannot rotate. When the polishing roller brush is tilted, it is easy to cause uneven polishing thickness and inadequate burr cleaning. Summary of the invention

A lower hopper is installed at one end of the bottom of the operating table, and the lower hopper is located at the bottom of the lower trough. The angle between the lower hopper and the top of the operating table is 45 degrees. A screen is installed on the lower hopper, and a discharge hopper is installed at the bottom of the lower hopper, and the angle between the discharge hopper and the lower hopper is 45 degrees.

[0022] By adopting the above technical solution, the lower hopper is shaken to make the debris fall better.

[0023] The method for using the automatic clamping hardware grinding device comprises the following steps:

[0024] S1. First install the drive motor and roller brush, and adjust the height. Then insert multiple parts into multiple discharge holes respectively. Through the operation of the servo motor, the rubber roller drives the parts to rotate, and the turntable drives the parts to be polished one by one. The polished parts fall out through the discharge chute, and at the same time, the space is vacated, and the parts can be put in again for polishing;

[0025] S2. When the turntable drives the part to rotate to one end of the pressure plate, the part can be ground. The pressure plate is resisted and contracted by the top block, and the part is clamped by the resisting wheel, making the part grinding more stable. After the grinding is completed, the part is taken away from the pressure plate by the turntable, so that the pressure plate is separated from the top block and the pressure plate is reset, so that the part will not be clamped, which is convenient for subsequent unloading and falling;

[0026] S3. When the pressure plate is moving and clamping, the tooth block and the bevel rack are in a one-way limit contact, so that the pressure plate can only clamp the parts without loosening. The bottom of the push rod is driven by the turntable to slide out of the slide slot, and the bottom of the push rod is contacted by the mounting plate, so that the push rod contacts the convex block on the tooth block, so that the tooth block is contacted and separated from the bevel rack, so that the pressure plate will not be limited, which is convenient for subsequent reset;

[0027] S4. The polished parts fall into the lower hopper for recovery, and the debris can be screened out. With the cooperation of the connecting spring and the connecting shaft, the lower hopper shakes after the parts fall, so that the debris falls better and does not block the screen. At the same time, the shaking plays a role in decompression, so that the parts will not be impacted and worn.

[0028] Compared with the prior art, the present invention has the following beneficial effects:

[0029] 1. The present invention installs the mounting frame through the operating table, so that the driving motor is supported and installed, thereby realizing the grinding of parts by the rotation of the roller brush, and the opening of the discharge hole through the installation of the turntable realizes the placement of parts. The turntable can be driven and controlled through the operation of the servo motor, which is conducive to the conveying and grinding of parts on the turntable. The polished parts are dropped and discharged through the discharge chute, and at the same time, the position is vacated for loading and grinding of parts again;

[0030] 2. The present invention drives the parts to move to the grinding position by the rotation of the turntable. The pressure plate is installed so that the pressure plate is resisted and contracted by the top block, and the part is clamped by the resisting wheel. When the roller brush grinds the surface of the part, the rubber roller drives the part to rotate. The roller brush and the part can be set to rotate in opposite directions, which is conducive to comprehensive grinding of the parts, making the grinding surface of the parts more uniform, avoiding the situation that the top grinding surface of the parts tilts to one side due to the tilt of the roller brush, and the grinding surface is uneven. After the grinding is completed, the parts are taken away from the pressure plate by the turntable, the pressure plate is separated from the top block, and the pressure plate is reset, so that the resisting wheel pair will not clamp the parts, which is convenient for subsequent unloading and falling;

[0031] 3. The present invention uses the matching installation of the clamping block and the bevel rack to enable the pressure plate to be limited in one direction when moving, so that the pressure plate can only clamp the parts through the abutment wheel and will not loosen, thus playing a role of limit protection. The bottom of the push rod is driven by the turntable to slide out of the slide groove, and the bottom end of the push rod is abutted by the mounting plate, so that the push rod abuts against the convex block on the tooth block, so that the tooth block is abutted and separated from the bevel rack, so that the pressure plate will not be limited, which is convenient for subsequent reset;

[0032] 4. The present invention cooperates with the lower hopper and the screen so that the fallen parts can be exported for recycling, and the debris can be classified and screened out to make the parts cleaner. With the cooperation of the connecting spring and the connecting shaft, the lower hopper shakes after the parts fall, so that the debris falls better and will not block the screen. At the same time, the shaking plays a role in reducing pressure, so that the parts will not be impacted and worn. BRIEF DESCRIPTION OF THE DRAWINGS

[0048] Embodiment 1: According to Figure 1 , Figure 2 , Figure 3 , Figure 5 , Figure 6 , Figure 7 , Figure 8 and Fig. 9 As shown, an automatic clamping hardware grinding device comprises an operating table 1, a grinding mechanism 2 is installed on the operating table 1, and the grinding mechanism 2 comprises a mounting frame 21, a mounting frame 21 is installed at one end of the top of the operating table 1, a pad 25 is detachably connected to the mounting frame 21, a driving motor 22 is detachably connected to the pad 25, a roller brush 26 is detachably connected to the output shaft of the driving motor 22, a cover shell 23 is detachably connected to the outer side of the driving motor 22, the cover shell 23 is located on the outer side of the roller brush 26, the cover shell 23 is a "9"-shaped structure, a dust suction pipe 24 is connected to the top of one end of the cover shell 23, and through the installation of the mounting frame 21, the dust suction pipe 24 can be used to remove the dust from the cover shell 23. The drive motor 22 is supported and installed, and the parts are polished with the cooperation of the roller brush 26. The drive motor 22 is supported with the cooperation of the pad 25. The height of the drive motor 22 can be adjusted by adding or reducing the pad 25, which is convenient for polishing parts of different lengths. The installation of the cover 23 plays a role in safety protection, and the debris generated by grinding can be thrown into the inner side of the cover 23 for export, reducing dust pollution to the environment. At the same time, the dust suction pipe 24 is connected to the external vacuum cleaner to achieve the removal and cleaning of the debris, and the export and recovery of large debris.

[0049] Furthermore, a material discharge mechanism 3 is installed on the operating table 1, and the material discharge mechanism 3 includes a mounting plate 31. The mounting plate 31 is installed at the top center of the operating table 1. A rotating shaft 33 is rotatably connected at the top center of the mounting plate 31. The rotating shaft 33 is a hexagonal prism structure. A turntable 32 is slidably connected to the rotating shaft 33. The bottom of the turntable 32 is in conflict with the mounting plate 31. A plurality of material discharge holes 37 distributed in an annular shape are provided at the edge of the turntable 32. Both ends of the material discharge holes 37 extend to the outside of both sides of the turntable 32. The material discharge holes 37 are located at the bottom of the roller brush 26. A material discharge trough 35 is provided at the edge of the mounting plate 31. The bottom of the material discharge trough 35 extends to the outside of the bottom of the operating table 1. A top cover 36 is threadedly connected to the top of the rotating shaft 33. The top cover 36 is in conflict with the top edge of the turntable 32. A servo motor 34 is installed at the bottom of the mounting plate 31. The output shaft of the servo motor 34 is connected to the rotating shaft 33. The rotating shaft 3 is realized by installing the mounting plate 31. 3 and the top cover 36 cooperate, so that the turntable 32 is placed stably and can rotate on the top of the mounting plate 31. Through the opening of multiple discharge holes 37, it is convenient to insert and place multiple parts. Through the installation of the servo motor 34, the drive control of the rotating shaft 33 and the turntable 32 is realized, so that the turntable 32 can rotate a certain angle on the top of the mounting plate 31, so that the parts inside the discharge holes 37 are rotated to the bottom of the roller brush 26 for grinding and working. When the turntable 32 stays for a certain time and the grinding is completed, it is rotated again by a certain angle to facilitate the grinding of another part. At the same time, the polished parts follow the turntable 32 to rotate to the top of the discharge trough 35, so that the parts fall through the discharge trough 35 for recovery. After the parts are unloaded, the discharge holes 37 are vacated to facilitate the parts to be unloaded again and wait for the grinding work. By analogy, the parts unloading, feeding, grinding, unloading and unloading are realized, which improves the efficiency of grinding and makes the operation more convenient.

[0050] Furthermore, the top block 41 is a trapezoidal structure, and a plurality of annularly distributed clamping grooves 44 are provided at the inner edge of the turntable 32, and the clamping grooves 44 are of a diamond structure. The clamping grooves 44 are connected to the discharge hole 37, and the clamping grooves 44 are located at the center of the discharge hole 37. The diameter of the discharge hole 37 is larger than the width of the clamping grooves 44. The pressure plate 43 is installed inside the turntable 32 and is provided with a plurality of pressure plates 43 distributed in an annular shape. A through-grooving card slot 46 is provided on the pressure plate 43, and the card slot 46 is of a diamond structure. The card slot 46 is equal in size to the clamping groove 44. The pressure plate 43 is slidably connected to the inside of the turntable 32 through a plurality of compression springs 47. One end of the pressure plate 43 extends to the outside of the turntable 32. The two pressure plates 43 form a group, and a pressure wheel 42 is rotatably connected between one end of the two pressure plates 43. The two clamping grooves 44 are located between the two pressure plates 43. Under the resistance of the compression springs 47, The pressing plate 43 is resisted and slides out, so that the card slot 46 and the clamping slot 44 remain in a vertical state. By opening the clamping slot 44, the card slot 46 and the clamping slot 44 on the pressing plate 43 are staggered, so that the parts are inserted into the clamping slot 44 and the card slot 46 through the discharge hole 37. When the turntable 32 carries the parts and rotates to the bottom of the roller brush 26, the pressure wheel 42 on the pressing plate 43 is resisted by the top block 41, and the pressure wheel 42 drives the two pressing plates 43 to get rid of the elastic force of the compression spring 47 and shrink, so that the card slot 46 and the clamping slot 44 are staggered and close, and the clamping work of the parts is realized by the resisting wheel, so that the parts are stably placed inside the discharge hole 37 and maintained in a vertical state, which is convenient for grinding work. When the grinding is completed, the parts are separated from the roller brush 26, the pressure wheel 42 is separated from the top block 41, and the pressing plate 43 will be reset, which is convenient for the parts to fall down for work.

[0051] Furthermore, a clamping block 45 is installed inside the turntable 32. A plurality of clamping blocks 45 are provided and distributed in a ring shape. One end of the clamping block 45 is a "C"-shaped structure. One end of the plurality of clamping blocks 45 extends into the clamping groove 44 respectively, so as to facilitate the clamping of parts.

[0052] Furthermore, a plurality of annularly distributed clamping mechanisms 4 are installed inside the turntable 32, and the clamping mechanisms 4 include a top block 41, and a top block 41 is installed at one end of the mounting plate 31. A pressure plate 43 and a clamping block 45 are connected to the turntable 32, and a resistance wheel 93 is installed at one end of the pressure plate 43 and the clamping block 45 close to the inner side of the discharge hole 37. A first gear 92 is rotatably connected to the turntable 32, and a limiting hole 96 is provided on the first gear 92. A limiting column 91 extending into the limiting hole 96 is installed on the mounting plate 31. A rubber roller 95 extending into the discharge hole 37 is rotatably connected to the clamping block 45, and a second gear 94 is installed on the shaft of the rubber roller 95. The second gear 94 is meshed with the first gear 92. When the pressure wheel 42 is pushed by the top block 41, the pressure plate 43 The first gear 92 is moved closer to the clamping block 45, thereby clamping the part inside the discharge hole 37. The abutment wheel 93 is in close contact with the outer wall of the part to limit the swing of the part. The outer wall of the part is in close contact with the rubber roller 95. When the turntable 32 rotates, the first gear 92 is limited by the limiting column 91, so that the first gear 92 and the turntable 32 move relative to each other, thereby driving the second gear 94 to move, and the second gear 94 drives the rubber roller 95 to rotate. Since the first gear 92 is directly larger than the second gear 94, the rotation speed of the rubber roller 95 is greater than that of the turntable 32. Therefore, when the roller brush 26 grinds the surface of the part, the rubber roller 95 drives the part to rotate, wherein the roller brush 26 and the part can be set to rotate in opposite directions, which is conducive to comprehensive grinding of the part.

[0053] Embodiment 2: According to Figure 5 , Fig. 9 , Fig.10 , Fig.11 and Fig.12 The adjusting mechanism 5 comprises a screw rod 52, a side wall of one end of the mounting plate 31 being vertically threadedly connected with the screw rod 52, one end of the screw rod 52 being rotatably connected with one side of the top block 41, the bottom of the top block 41 being slidably connected with the mounting plate 31, and the other end of the screw rod 52 being installed with a twisting knob 53. The two ends of one side of the top block 41 are vertically connected with a guide plate 51, and one end of the guide plate 51 is slidably connected with the side wall of the mounting plate 31. The driving control of the top block 41 is realized through the threaded connection of the screw rod 52. The distance between the top block 41 and the outer side of the turntable 32 is changed by rotating the twisting knob 53, so as to realize the control of the clamping force of the parts, and facilitate the good clamping work of parts of different sizes. With the cooperation of the guide plate 51, the top block 41 slides smoothly and stably without offset, which is beneficial to the subsequent resistance work of the pressure wheel 42.

[0054] Furthermore, a plurality of locking mechanisms 6 are installed in a ring-shaped arrangement inside the turntable 32. The locking mechanism 6 includes a beveled rack 62. The beveled racks 62 are symmetrically installed on both sides of one end of one of the pressure plates 43. Symmetrical tooth blocks 61 are connected in a ring-shaped arrangement inside the turntable 32. The tooth blocks 61 are slidably connected to the inside of the turntable 32 through a return spring 63. One end of the symmetrical tooth blocks 61 abuts against the beveled rack 62. The sharp teeth at one end of the tooth blocks 61 are opposite to the sharp teeth at one side of the beveled rack 62. Under the abutment of the return spring 63, the tooth blocks 61 are locked. The block 61 contacts with the bevel rack 62, and the tooth block 61 is retractable inside the turntable 32. When the pressure plate 43 is contacted to clamp the part, the bevel rack 62 moves at one end of the tooth block 61, and the bevel rack 62 contacts and shrinks against the tooth block 61, which facilitates the movement of the bevel rack 62. Since the sharp teeth at one end of the tooth block 61 are in opposite directions to the sharp teeth on one side of the bevel rack 62, after the bevel rack 62 moves, the tooth block 61 resets and continues to contact, and the rack cannot move in the opposite direction, which is beneficial to the one-way limiting effect of the bevel rack 62 after it moves, so that the part will not loosen after being clamped.

[0055] Furthermore, a plurality of annularly distributed abutment mechanisms 7 are installed inside the turntable 32, and the abutment mechanisms 7 include push rods 76.

The protrusion 73 is a hemispherical structure, and the top of the push rod 76 extends to the inner side of the bottom of the movable groove 72 and is located at the bottom of the protrusion 73. The top of the push rod 76 is an arc structure, and a slide groove 71 is provided on the top of the mounting plate 31. The slide groove 71 is a three-quarter circular structure, and the slide groove 71 is located at the bottom of the plurality of groups of push rods 76.
