Description

Technical Field

[0001] This utility model relates to the field of nut processing technology, and specifically discloses a burr removal device for nut processing. Background Technology

[0002] In the field of mechanical manufacturing, nuts are basic fasteners, and their machining quality directly affects assembly accuracy and safety. In the traditional nut machining process, burrs are generated on the internal threads and edges after the tapping process. Currently, manual grinding or fixed deburring equipment is commonly used to remove these burrs.

[0003] In existing technologies, fixed deburring equipment mostly uses a single-specification rotating brush head with a fixed clamp, which has significant limitations: on the one hand, different nut specifications require replacement of the entire machine or complex tooling adjustments, resulting in low equipment utilization and increased production costs; on the other hand, traditional equipment lacks an effective chip collection system, and the metal chips generated during grinding easily spread in the work area, not only polluting the working environment but also posing a risk of secondary chip adhesion to the workpiece surface, affecting cleanliness. Especially for multi-faceted workpieces such as hexagonal nuts, the clamping mechanisms of existing equipment often struggle to achieve precise centering and positioning, easily leading to uneven deburring. Therefore, there is an urgent need to develop a deburring device with quick changeover capabilities, adaptable to the processing needs of multiple nut specifications, and integrating an efficient chip collection system to improve processing efficiency and ensure the cleanliness of the working environment.

[0025] The present invention will be further described below with reference to the accompanying drawings and specific embodiments to aid in understanding its content. Unless otherwise specified, the methods used in this invention are conventional methods; the raw materials and apparatus used, unless otherwise specified, are conventional commercially available products.

[0026] Please see Figure 1-5 A burr removal device for nut processing, comprising:

[0027] The bottom box 1 has a flat plate 2 fixedly connected to its upper end surface, and a round hole 3 is opened on the upper end surface of the flat plate 2.

[0028] The burr removal assembly 4 is installed inside the base box 1 and includes a rotating roller 5. Four telescopic guide rods 6 are movably connected to the outer wall of the rotating roller 5. The four guide rods 6 are evenly distributed around the circumference of the rotating roller 5 and an arc-shaped plate 7 is fixedly connected to the other end of each of the four arc-shaped plates 7. A wire brush 8 is fixedly connected to the outer wall of each of the four arc-shaped plates 7. Two springs 9 are fixedly connected between the arc-shaped plates 7 and the rotating roller 5.

[0029] The clamping assembly includes slide rails 10 fixedly connected to the left and right sides of the upper end face of the plate 2. Slide plates 11 are slidably connected to the upper end face of both slide rails 10. An extension plate 12 is fixedly connected to the back of the plate 2. A cylinder 13 is installed on the upper end face of the extension plate 12. A movable plate 14 is fixedly connected to the output end of the cylinder 13. A connecting rod 15 is hinged between the movable plate 14 and the two slide plates 11.

[0030] Debris collection facility.

[0031] In this embodiment: the cylinder 13 is activated, and the cylinder 13 pushes the movable plate 14 to slide horizontally along the linear guide rail 24 on the extension plate 12. The movable plate 14 pulls the two sliding plates 11 on the slide rail 10 to move towards each other through the hinged connecting rod 15. The right-angle plate 23 at the end of the sliding plate 11 clamps the nut to achieve precise centering and positioning.

[0032] The electric actuator 16 lifts the motor 25 upward, driving the rotating roller 5 on the mounting base 17 to pass through the round hole 3 of the plate 2 and enter the inner cavity of the nut. The motor 25 drives the rotating roller 5 to rotate at high speed, and the wire brush 8 contacts the inner wall of the nut to remove burrs. The spring 9 pushes the guide rod 6 to extend outward, causing the arc-shaped plate 7 to expand radially. The wire brush 8 adaptively conforms to the threaded surface to perform all-round grinding, improving the uniformity and efficiency of burr removal.

[0033] During the processing, the debris generated falls into the collection hood 20 through the round hole 3. After the fan 21 is started, a negative pressure is formed, and the debris is carried by the airflow through the pipe into the dust collection bag 22 for centralized storage, reducing environmental pollution and lowering cleaning costs.

[0034] After processing, cylinder 13 retracts to release the clamp, electric push rod 16 lowers the roller 5 to disengage from the nut, and the hexagonal screw 19 at the bottom of the roller 5 is separated from the hexagonal screw hole 18 of the mounting base 17. Rollers 5 of other specifications can be replaced to adapt to different nuts and meet the processing needs of multiple nut specifications.

[0035] As a technical optimization of this utility model, the burr removal component 4 also includes an electric push rod 16 installed inside the lower part of the base box 1. A motor 25 is installed at the output end of the electric push rod 16, and a mounting base 17 is fixedly connected to the output end of the motor 25. A hexagonal screw hole 18 is opened on the upper end surface of the mounting base 17, and a hexagonal screw 19 matching the hexagonal screw hole 18 is fixedly connected to the bottom of the rotating roller 5.

[0036] In this embodiment: the electric actuator 16 precisely controls the lifting height of the roller 5, adapting to the processing requirements of nuts of different thicknesses; the cooperation between the hexagonal screw hole 18 and the hexagonal screw 19 not only enables quick disassembly and replacement of the roller 5, but also restricts the relative rotation between the roller 5 and the motor 25 through the non-circular cross section, ensuring the reliability of power transmission.

[0037] As a technical optimization of this utility model, the debris collection mechanism includes a collection cover 20 fixedly connected to the center of the lower end face of the plate 2. The piston rod of the electric push rod 16 is slidably connected to the bottom of the collection cover 20 through a sliding sealing sleeve. A fan 21 is installed on the outside of the collection cover 20. One end of the fan 21 is connected to the collection cover 20 through a pipe, and the other end extends to the outside of the bottom box 1 through a pipe and is detachably connected to a dust collection bag 22.

[0038] In this embodiment: the sliding sealing sleeve prevents debris from entering the bottom box 1 and contaminating the electric push rod 16, while ensuring the sealing of the collection cover 20 when the electric push rod 16 is raised and lowered. The fan 21 and the dust collection bag 22 form a closed-loop recycling system to prevent debris from overflowing, thereby improving environmental protection and ease of cleaning.

[0039] As a technical optimization of this utility model, a right-angle plate 23 is fixedly connected to one end of each of the two sliding plates 11 facing each other.

[0040] In this embodiment: the right-angle plate 23 increases the contact area with the inner hole of the nut to prevent slippage during clamping, and at the same time, the right-angle edge limits the nut to achieve rapid centering, thereby improving clamping accuracy and stability.

[0041] As a technical optimization of this utility model, the upper end face of the extension plate 12 is fixedly connected to the linear guide rail 24, and the movable plate 14 is slidably connected to the outer wall of the linear guide rail 24.

[0042] In this embodiment, the linear guide rail 24 constrains the movement trajectory of the movable plate 14, preventing it from tilting when the cylinder 13 pushes it, ensuring that the two sliding plates 11 move synchronously, and further ensuring the clamping symmetry.

[0043] As a technical optimization of this utility model, multiple rotating rollers 5 are provided, and the multiple rotating rollers 5 are of different diameters and specifications.

[0044] In this embodiment, by replacing the rotating roller 5 with nuts of different inner diameters, the applicable range of the device is expanded, downtime for adjustment is reduced, and production efficiency is improved.

[0045] As a technical optimization of this utility model, the cylinder 13, electric push rod 16, fan 21 and motor 25 are all electrically connected to the external control system.

[0046] In this embodiment, the external control system centrally controls the coordinated actions of each actuator (such as clamping, lifting, rotating, and vacuuming starting and stopping simultaneously) to achieve automated processing, reduce the intensity of manual intervention, and improve operational safety and processing consistency.

[0047] The working principle and usage process of this utility model are as follows: During use, cylinder 13 is activated, pushing the movable plate 14 to slide horizontally along the linear guide rail 24 on the extension plate 12. The movable plate 14, through the hinged connecting rod 15, pulls the two side slide plates 11 to move towards each other on the slide rail 10. The right-angle plate 23 at the end of the slide plate 11 clamps the nut, achieving precise centering. The electric push rod 16 lifts the motor 25 upwards, driving the rotating roller 5 on the mounting base 17 to pass through the round hole 3 of the plate 2 and enter the inner cavity of the nut. The motor 25 drives the rotating roller 5 to rotate at high speed, and the wire brush 8 contacts the inner wall of the nut, thereby performing… In the deburring process, the spring 9 pushes the guide rod 6 outward to extend the arc-shaped plate 7 radially. The wire brush 8 adapts to the threaded surface for all-round grinding. The debris generated during the processing falls into the collection cover 20 through the round hole 3. After the fan 21 is started, a negative pressure is formed, and the debris is carried by the airflow through the pipe into the dust collection bag 22 for centralized storage. After the processing is completed, the cylinder 13 retracts to release the clamp, the electric push rod 16 lowers the roller 5 to disengage from the nut, and the hexagonal screw 19 at the bottom of the roller 5 is separated from the hexagonal screw hole 18 of the mounting base 17. Other specifications of roller 5 can be replaced to meet the processing requirements of different nuts.
