The present invention relates to the technical field of burr treatment, and discloses a burr treatment device for part processing, including a grinding body and a grinding assembly installed on one side of the grinding body for grinding hexagonal nuts. An installation groove is provided on one side of the grinding body. Fixed rods are arranged above and below the grinding assembly. A power assembly for controlling the movement of the fixed rods is arranged in the installation groove. In the present invention, a toothed ring is fixedly sleeved outside the fixed rod, and a limiting arc-shaped block is slidably arranged in the chute on the side wall of the installation groove. After deburring one side of the hexagonal nut by grinding, the fixed rod is controlled to drive the hexagonal nut to move. During the movement of the fixed rod, the toothed ring contacts the right-angle surface of the limiting arc-shaped block and rotates to control the hexagonal nut to change its surface. When the fixed rod is controlled to drive the hexagonal nut to move back to its original position, the toothed ring contacts the arc-shaped surface of the limiting arc-shaped block, pushing the limiting arc-shaped block into the chute, and the toothed ring does not rotate, which is convenient for timely changing the surface of the hexagonal nut to remove burrs.

Description

Technical Field

[0001] The present invention relates to the technical field of burr treatment, and specifically relates to a burr treatment device for part processing. Background Art

[0002] Hexagonal nuts are common parts in mechanical equipment and are used to fasten equipment. During the production process of hexagonal nuts, deburring treatment is required. Existing special equipment for deburring hexagonal nuts, such as the hexagonal nut deburring machine disclosed in the authorized announcement number CN219901504U, includes a fixed installation base. A first drive motor is installed inside the left end of the fixed installation base. A convex plate is provided at the upper middle of the movable cross plate. An activity installation bottom plate connected to the fixed installation base is provided outside the convex block. An adjusting rod is provided at the upper end of the support rod. A first rubber pad is provided on the upper surface of the support rod below the hexagonal nut body. This hexagonal nut deburring machine is conducive to stable connection and installation, avoids the inability to disassemble and replace vulnerable parts in a timely manner, can be adjusted for intermittent rotation as needed, and improves the practical effect of the device.

[0003] When deburring the outer side surface of a hexagonal nut, it is polished one side at a time. Similar to the above-mentioned prior art, the hexagonal nut can be rotated to a different side. However, the outer side surface of the existing hexagonal nut is a flat surface. In the above-mentioned prior art, it is polished by a circular grinding base and a sanding disc. It is impossible to polish an entire side surface of the hexagonal nut. Moreover, the hexagonal nut is fixed by bolts, and it is rather troublesome to change the side. Since the side surface of the hexagonal nut directly contacts the sanding disc, the hexagonal nut cannot be directly rotated to change the side. Summary of the Invention

[0004] Aiming at the deficiencies of the prior art, the present invention provides a burr treatment device for part processing, which can achieve comprehensive polishing and can timely change the hexagonal nut.

[0005] To achieve the above object, the present invention provides the following technical solution: A burr treatment device for part processing, including a grinding body and a grinding component installed on one side of the grinding body for grinding hexagonal nuts. An installation groove is provided on one side of the grinding body. Fixed rods are provided above and below the grinding component. A power component for controlling the movement of the fixed rods is provided in the installation groove. A limiting member is provided between the fixed rods and the power component. Tooth rings are fixedly sleeved on the outer sides of the two fixed rods. A limiting component for controlling the rotation of the tooth rings is provided on the side wall of the installation groove. The limiting component is used to control the surface change of the hexagonal nut. A fixing member and a pre-positioning member for fixing the hexagonal nut are provided on the outer side of the fixed rod. A connecting member for pushing the fixing member to move is installed on one side of the grinding body.

[0006] Preferably, the power assembly includes a gear rotatably connected to the side wall of the installation groove. Tooth plates slidably connected to the side wall of the installation groove are meshed on both sides of the gear. The gear is meshed with the tooth plates. Collars are fixedly installed at one ends of the two tooth plates. An electric push rod is fixedly installed on the side wall of the installation groove, and the working end of the electric push rod is fixedly connected to one of the tooth plates.

[0007] Preferably, the limiting member includes a plurality of arc-shaped limiting plates fixedly installed on the outside of the fixed rod. The arc-shaped limiting plates are elastically arranged, and limiting grooves for limiting the arc-shaped limiting plates are formed on the inner side of the collar.

[0008] Preferably, the limiting assembly includes a plurality of sliding grooves formed in the side wall of the installation groove. Limiting arc-shaped blocks are slidably arranged in the sliding grooves, and telescopic springs are fixedly arranged between the limiting arc-shaped blocks and the sliding grooves.

[0009] Preferably, the fixing member includes support plates located on both sides of the fixed rod. Two connecting blocks are fixedly installed at one end of the fixed rod. A first rotating rod and a second rotating rod are rotatably installed on the inner side of the support plate. One end of the first rotating rod is rotatably connected to the connecting block. A push rod slidably connected to the fixed rod is rotatably arranged at one end of the second rotating rod. An installation opening is formed on the outside of the fixed rod. An annular plate slidably connected to the installation opening is sleeved on the outside of the fixed rod. A connecting spring is fixedly arranged between the annular plate and the installation opening, and the push rod is fixedly connected to the annular plate.

[0010] Preferably, the connecting member includes a push plate fixedly installed on one side of the grinding body. One side of the annular plate is in sliding contact with the push plate, and an inclined angle is formed on one side of the push plate.

[0011] Preferably, the pre-positioning member includes two sliding openings formed in the outside of the fixed rod. An arc-shaped housing is slidably connected in the sliding openings, and a reset spring is fixedly arranged between the arc-shaped housing and the sliding openings.

[0012] Preferably, the grinding assembly includes a fixing plate fixedly installed on one side of the grinding body. A double-shaft motor is fixedly installed on the fixing plate, and a grinding disc is fixedly installed at the output end of the double-shaft motor.

[0013] Preferably, a controller is fixedly installed on one side of the grinding body, and the controller is electrically connected to the double-shaft motor and the electric push rod.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. The present invention fixes a toothed ring on the outside of a fixing rod, slides a limit arc block in a slide groove on the side wall of the installation groove, and after one side of the hexagonal nut is polished and deburred, controls the fixing rod to drive the hexagonal nut to move. During the movement of the fixing rod, the toothed ring contacts the right-angled surface of the limit arc block and rotates to control the face change of the hexagonal nut. When the fixing rod is controlled to drive the hexagonal nut to move and reset, the toothed ring contacts the arc surface of the limit arc block and pushes the limit arc block into the slide groove. The toothed ring does not rotate, which is convenient for timely face change and deburring of the hexagonal nut.

[0016] 2. The present invention installs a plurality of arc-shaped limit plates at equal intervals on the outside of a fixed rod. When the gear ring contacts the right-angle surface of the limit arc block, the arc-shaped limit plates rotate. When the hexagonal nut is changed, the arc-shaped limit plates are squeezed. When the gear ring contacts the arc surface of the limit arc block, the arc-shaped limit plates are limited by the limit grooves to prevent the gear ring from rotating.

[0017] 3. The present invention arranges support plates on both sides of the fixed rod, a first rotating rod rotating inside the support plate is rotatably connected to a connecting block on the fixed rod, a second rotating rod rotating inside the support plate is rotatably connected to a push rod on the annular plate, an annular plate in sliding contact with the push plate is installed on one side of the grinding body, when the fixed rod is controlled to move away from the grinding disk, the support plate can be controlled to move away from the inner side of the hexagonal nut through the cooperation of the annular plate, the push plate and the connecting spring, so that the hexagonal nut can be removed and replaced conveniently, and push plates of different sizes can be replaced to adapt to the grinding of hexagonal nuts of different sizes.

Specific implementation manner

[0028] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Embodiment

[0029] Please refer to Figures 1-9 , a burr treatment device for part processing, including a grinding machine body 1 and a grinding component installed on one side of the grinding machine body 1 for grinding the hexagon nut 3. The grinding component includes a fixing plate 2 fixedly installed on one side of the grinding machine body 1. A dual-shaft motor 4 is fixedly installed on the fixing plate 2. A grinding disc 9 is fixedly installed at the output end of the dual-shaft motor 4. An installation groove 5 is opened on one side of the grinding machine body 1. Fixing rods 6 are arranged above and below the grinding component, and the burrs of two groups of hexagon nuts 3 can be ground and removed simultaneously;

[0030] A power component for controlling the movement of the fixing rod 6 is arranged in the installation groove 5. A limiting member is arranged between the fixing rod 6 and the power component. Tooth rings 16 are fixedly sleeved on the outer sides of the two fixing rods 6. A limiting component for controlling the rotation of the tooth ring 16 is arranged on the side wall of the installation groove 5. The limiting component is used for controlling the hexagon nut 3 to change its face. The power component includes a gear 13 rotatably connected to the side wall of the installation groove 5. Tooth plates 14 slidably connected to the side wall of the installation groove 5 are meshed on both sides of the gear 13. The gear 13 is meshed with the tooth plates 14. Sleeve rings 11 are fixedly installed at one ends of the two tooth plates 14. An electric push rod 12 is fixedly installed on the side wall of the installation groove 5. The working end of the electric push rod 12 is fixedly connected to one of the tooth plates 14. The limiting component includes a plurality of sliding grooves 24 opened on the side wall of the installation groove 5. Limiting arc-shaped blocks 18 are slidably arranged in the sliding grooves 24. A telescopic spring 25 is fixedly arranged between the limiting arc-shaped block 18 and the sliding groove 24. After burrs are removed by grinding on one face of the hexagon nut 3, the electric push rod 12 is started to work. Through the cooperation of the gear 13 and the tooth plates 14, the two fixing rods 6 can be controlled to drive the two hexagon nuts 3 to move away from the grinding disc 9. During the movement of the fixing rod 6, the tooth ring 16 contacts the right-angle surface of the limiting arc-shaped block 18 and rotates, which is used to control the hexagon nut 3 to change its face. When the electric push rod 12 is started to work continuously and the fixing rod 6 is controlled to drive the hexagon nut 3 to move back to its original position, the tooth ring 16 contacts the arc-shaped surface of the limiting arc-shaped block 18, and the limiting arc-shaped block 18 is pushed into the sliding groove 24, and the tooth ring 16 does not rotate, which is convenient for removing burrs on the hexagon nut 3 by changing its face in time;

[0031] A fixing member and a pre-positioning member for fixing the hexagon nut 3 are arranged on the outer side of the fixing rod 6. A connecting member for pushing the fixing member to move is installed on one side of the grinding body 1. The fixing member includes support plates 20 located on both sides of the fixing rod 6. Two connecting blocks 30 are fixedly installed at one end of the fixing rod 6. A first rotating rod 31 and a second rotating rod 23 are rotatably installed on the inner sides of the support plates 20. One end of the first rotating rod 31 is rotatably connected to the connecting block 30. A push rod 15 slidably connected to the fixing rod 6 is rotatably arranged at one end of the second rotating rod 23. An installation opening 19 is opened on the outer side of the fixing rod 6. An annular plate 10 slidably connected to the installation opening 19 is sleeved on the outer side of the fixing rod 6. A connecting spring 17 is fixedly arranged between the annular plate 10 and the installation opening 19. The push rod 15 is fixedly connected to the annular plate 10. The connecting member includes a push plate 8 fixedly installed on one side of the grinding body 1. One side of the annular plate 10 is in sliding contact with the push plate 8. An inclined angle 7 is opened on one side of the push plate 8. After the grinding work is completed, the electric push rod 12 is started to work, and the fixing rod 6 is controlled to move away from the grinding disc 9. The annular plate 10 first contacts the flat surface of the push plate 8. At this time, the support plate 20 abuts against the inner side of the hexagon nut 3 to fix the hexagon nut 3. When the fixing rod 6 continues to move, the annular plate 10 contacts the inclined angle 7 of the push plate 8. Through the push of the connecting spring 17, the support plate 20 is separated from the inner side of the hexagon nut 3. At this time, it is convenient to remove the hexagon nut 3 and replace it with a new hexagon nut 3 for deburring treatment;

[0032] A controller 27 is fixedly installed on one side of the grinding body 1, and the controller 27 is electrically connected to the double-shaft motor 4 and the electric push rod 12.

[0033] As a further technical solution of the present invention, the limiting member includes a plurality of arc-shaped limiting plates 21 fixedly installed on the outer side of the fixed rod 6. The arc-shaped limiting plates 21 are elastically arranged. A limiting groove 26 for limiting the arc-shaped limiting plates 21 is opened on the inner side of the collar 11. When the right-angle surface of the tooth ring 16 contacts the limiting arc-shaped block 18 and rotates, for controlling the chamfering of the hexagonal nut 3, the arc-shaped limiting plates 21 are squeezed. When the arc-shaped surface of the tooth ring 16 contacts the limiting arc-shaped block 18, the arc-shaped limiting plates 21 are limited through the limiting groove 26 to prevent the tooth ring 16 from rotating at this time.

[0034] As a further technical solution of the present invention, the pre-positioning member includes two sliding openings 28 opened on the outer side of the fixed rod 6. An arc-shaped housing 22 is slidably connected in the sliding openings 28. A return spring 29 is fixedly arranged between the arc-shaped housing 22 and the sliding openings 28. When taking and placing the hexagonal nut 3, any plane of the hexagonal nut 3 can be placed parallel to the grinding disc 9 (this device can simultaneously grind parts similar to the hexagonal nut 3, not only six sides, but also five sides, four sides, etc., as long as one of the planes is controlled to be placed parallel to the grinding disc 9). The hexagonal nut 3 is fixed through the arc-shaped housing 22 to prevent the hexagonal nut 3 from moving greatly during the moving process.

[0035] Working principle:

[0036] At this time, the annular plate 10 is located at the bevel 7 of the push plate 8, and the support plate 20 does not abut against the inner side of the hexagonal nut 3. The hexagonal nut 3 can be placed on the outer side of the fixed rod 6 (when placing, any plane of the hexagonal nut 3 is placed parallel to the grinding disc 9). During the placing process, the arc-shaped housing 22 will be squeezed to move, the return spring 29 is squeezed, and the outer side of the arc-shaped housing 22 abuts against the inner side of the hexagonal nut 3 to pre-fix the hexagonal nut 3 and prevent the hexagonal nut 3 from moving greatly during the subsequent moving process;

[0037] Start the electric push rod 12 to work, drive the tooth plate 14 connected thereto to move. Through the cooperation of the gear 13 and the other tooth plate 14, the two collars 11 can be controlled to move. The collars 11 drive the two hexagonal nuts 3 to move towards the direction of the grinding disc 9. During the moving process, the fixed rod 6 drives the annular plate 10 to disengage from the bevel 7 and move to the plane of the straight push plate 8. The connecting spring 17 is squeezed, and the annular plate 10 pushes the push rod 15 to move, and the first rotating rod 31 and the second rotating rod 23 rotate, pushing the support plate 20 to abut against the inner side of the hexagonal nut 3 to fix the hexagonal nut 3;

[0038] The electric push rod 12 continues to work, and the fixed rod 6 continues to move. The fixed rod 6 drives the toothed ring 16 to contact the arc surface of the limit arc-shaped block 18, pushing the limit arc-shaped block 18 into the sliding groove 24. The toothed ring 16 does not rotate (when the toothed ring 16 contacts the arc surface of the limit arc-shaped block 18, the arc-shaped limit plate 21 is limited by the limit groove 26 to prevent the toothed ring 16 from rotating at this time) until the hexagonal nut 3 contacts the grinding disc 9, and the grinding disc 9 can perform deburring treatment on it;

[0039] After deburring one side of the hexagonal nut 3, start the electric push rod 12 to work. Through the cooperation of the gear 13 and the toothed plate 14, it is possible to control the two fixed rods 6 to drive the two hexagonal nuts 3 to move away from the grinding disc 9. During the movement of the fixed rod 6, the toothed ring 16 contacts the right-angle surface of the limit arc-shaped block 18 and rotates, which is used to control the hexagonal nut 3 to change its surface (when the toothed ring 16 contacts the right-angle surface of the limit arc-shaped block 18 and rotates to control the hexagonal nut 3 to change its surface, the arc-shaped limit plate 21 is squeezed). Continue to start the electric push rod 12 to work. When controlling the fixed rod 6 to drive the hexagonal nut 3 to move back to its original position, the toothed ring 16 contacts the arc surface of the limit arc-shaped block 18, pushing the limit arc-shaped block 18 into the sliding groove 24, and the toothed ring 16 does not rotate, which is convenient for timely changing the surface and removing burrs of the hexagonal nut 3;

[0040] After the grinding work is completed, start the electric push rod 12 to work, control the fixed rod 6 to move away from the grinding disc 9. The annular plate 10 first contacts the plane of the push plate 8. At this time, the support plate 20 abuts against the inner side of the hexagonal nut 3. The fixed rod 6 continues to move, and the annular plate 10 contacts the bevel 7 of the push plate 8. Through the push of the connecting spring 17, the support plate 20 is separated from the inner side of the hexagonal nut 3. At this time, it is convenient to remove the hexagonal nut 3 and replace it with a new hexagonal nut 3 for deburring treatment.
