Description

Technical Field

[0001] The utility model relates to the technical field of deburring devices, and particularly relates to a core rod deburring device. Background Art

[0002] A core rod is a rod widely used in various mechanical and electrical equipment, with various types and functions. A core rod usually refers to a slender rod-shaped part, whose shape, material and use vary according to the application scenario; according to different classification criteria, core rods can be divided into various types, such as cylindrical core rods, threaded core rods, stepped core rods, hollow core rods, etc. These core rods play roles such as support, transmission, and guidance in mechanical equipment. The core rod is obtained by cutting and processing from steel, and it is difficult to avoid burrs on the surface of the core rod during transportation and processing. Deburring the core rod aims to improve the quality and performance of the core rod.

[0003] In the prior art, after the core rod is clamped by a machine tool, the machine tool rotates the core rod and then an operator uses sandpaper to polish the surface of the core rod. To improve the polishing effect, usually two types of sandpaper with different polishing fineness are used for polishing, namely rough polishing and fine polishing. The manual polishing method has low polishing efficiency and cannot effectively ensure the polishing effect of rough polishing and fine polishing on the core rod. Content of the Utility Model

[0004] The utility model aims to provide a core rod deburring device to provide a device that can perform rough polishing and fine polishing on the core rod.

[0005] To solve the above problems, the utility model provides the following technical solution:

[0006] A core rod deburring device includes a frame, on which a machine tool is provided. The frame is vertically and slidably connected with a sliding plate along the central axis symmetry of the machine tool. A spring is fixedly arranged between the sliding plate and the frame. Each sliding plate is fixedly connected with a polishing cylinder opposite to the central axis of the machine tool. The polishing fineness of the two polishing cylinders on both sides is different; the frame is also fixedly provided with a cylinder, and the cylinder drives a frame that alternately moves the two sliding plates.

[0007] Working Principle and Beneficial Effects of the Utility Model:

[0008] In this solution, the mandrel is clamped by the machine tool. The mandrel is located between the grinding cylinders on both sides. At this time, the frame is driven downward by the air cylinder. The top of the frame pushes the upper grinding cylinder to move and press the mandrel, and the spring at the top is compressed. The bottom of the frame moves away from the lower grinding cylinder. At this time, the machine tool drives the mandrel to rotate, and the grinding cylinders perform rough grinding on the mandrel. After the rough grinding is completed, the air cylinder drives the frame to move upward. The top of the frame disengages from the upper grinding cylinder, and the compressed spring at the top returns, causing the upper grinding cylinder to disengage from the mandrel. While the bottom of the frame squeezes the lower grinding cylinder to press the mandrel, and at this time, fine grinding can be carried out.

[0009] In this solution, the frame is driven to move by the air cylinder, so as to adjust the grinding cylinders on both sides to perform rough grinding and fine grinding on the mandrel in a certain order. In this grinding method, the grinding cylinders always keep uniform contact with the mandrel, so as to achieve a better grinding effect.

[0010] Optimally, the sliding plates are symmetrically arranged along the axis of the frame. The up-and-down movement trajectories of the grinding cylinders are restricted by the sliding plates on both sides, making the grinding process of the grinding cylinders more stable.

[0011] Optimally, the air cylinder is close to the central axis of the frame. This optimized solution makes the grinding more uniform when the grinding cylinders grind the mandrel.

[0012] Preferably, a negative pressure machine is provided on the frame. The negative pressure machine is used to adsorb the debris generated during the grinding process.

[0013] Optimally, the grinding fineness of the grinding cylinders on both sides is 400 mesh and 800 mesh respectively. Rough grinding and fine grinding are achieved under this grinding fineness.

[0014] Optimally, the frame is provided with rubber pads that contact the sliding plates. Description of the Drawings

[0021] The following is a further detailed description through specific implementation modes:

[0022] The reference numerals in the attached drawings of the specification include: lower grinding cylinder 1, cylinder 2, lower sliding plate 3, machine tool 4, frame 5, upper grinding cylinder 6, upper sliding plate 7, sliding groove 8, spring 9, machine frame 10, and core rod 11.

[0023] In the following statements, orientation terms such as "left", "right", "upper", and "lower" are based on the orientation shown in the drawings. In practice, if the corresponding structures change in the same direction based on the orientation and maintain the relative positions unchanged, it does not affect the implementation of the solution.

[0024] Embodiment: A deburring device for a core rod includes a machine frame 10, and a machine tool 4 is installed on the machine frame 10. The machine tool 4 is a commonly used processing device in the art, and its specific structure and working principle will not be elaborated here. For specific reference, refer to the prior art CN218136875U.

[0025] As Figure 1 and Figure 4 shown, the machine frame 10 is symmetrically provided with sliding grooves 8 along the center axis of the machine tool 4. The sliding grooves 8 are vertically slidably connected with sliding plates, and springs 9 are fixedly arranged between the sliding plates and the machine frame 10, namely the upper sliding plate 7 and the lower sliding plate 3 respectively. The upper sliding plate 7 is fixedly provided with an upper grinding cylinder 6 opposite to the core rod 11, the lower sliding plate 3 is fixedly provided with a lower grinding cylinder 1 opposite to the core rod 11, and the cylinder 2 drives a frame 5 that alternately abuts against the two sliding plates on both sides.

[0026] In this solution, the core rod 11 is clamped by the machine tool 4, and the core rod 11 is located between the lower grinding cylinder 1 and the upper grinding cylinder 6. As Figure 2 and Figure 5 shown, the cylinder 2 drives the frame 5 to move downward. The top of the frame 5 pushes the upper sliding plate 7 and the upper grinding cylinder 6 to move downward. The upper grinding cylinder 6 contacts the core rod 11, and the spring 9 at the top is compressed. The bottom of the frame 5 moves away from the lower sliding plate 3, and the machine tool 4 drives the core rod 11 to rotate. The upper grinding cylinder 6 performs rough grinding on the core rod 11; as Figure 3 and Figure 6 shown, after the rough grinding is completed, the cylinder 2 drives the frame 5 to move upward. The top of the frame 5 disengages from the upper sliding plate 7, and the compressed spring 9 at the top returns, causing the upper grinding cylinder 6 to disengage from the core rod 11. However, the bottom of the frame 5 presses the lower grinding cylinder 1 at the bottom to contact the core rod 11, and at this time, fine grinding can be performed.

[0027] In this solution, the cylinder 2 drives the frame 5 to move up and down, so as to adjust the upper grinding cylinder 6 and the lower grinding cylinder 1 to respectively perform rough grinding and fine grinding on the core rod 11 in a certain order. In such a grinding method, the upper grinding cylinder 6 and the lower grinding cylinder 1 always keep uniform contact with the core rod 11, so as to achieve a better grinding effect.

[0028] The standard parts used in the present utility model can all be purchased from the market. The special-shaped parts can be customized according to the description in the specification and the drawings. The specific connection methods of each part all adopt conventional means such as bolts, rivets, welding, etc. that are mature in the prior art. The machines, parts and equipment all adopt conventional models in the prior art, and the circuit connection adopts the conventional connection method in the prior art, which will not be elaborated here.
