Description

Technical Field

[0001] This utility model relates to the field of sizing roller processing technology, and in particular to a grinding device for sizing roller processing. Background Technology

[0002] Sizing rolls are key production components in the rolling industry. By adjusting the diameter, layout, and position of sizing rolls, the required dimensional accuracy of workpieces such as steel ingots and billets can be ensured. Especially in seamless tube continuous rolling production lines, their importance to rolling efficiency and rolling quality is even more evident. During the production and processing of sizing rolls, their outer surface needs to be ground, which requires the use of grinding equipment.

[0003] Chinese utility model patent (CN220279111U) discloses a grinding device for sizing roller processing, including a housing, a vertical plate, and a tensioning mechanism. A mounting frame is fixedly installed inside the housing, and gears are installed inside the housing. A material placement column is installed on the housing and mounting frame, and a sizing roller is mounted on the outer wall of the material placement column. The vertical plate is fixedly installed on the top of the housing, and a vertical plate and threaded rod are installed on the vertical plate. A sponge abrasive block is placed on the vertical plate. The tensioning mechanism is installed on the housing and the material placement column, and can be used to tension and limit the sizing roller. This technical solution allows for the grinding of sizing rollers of different sizes by adjusting the left and right movement of the sponge abrasive block and the rotation of the material placement column, improving the device's mobility and practicality. However, due to the irregular shape and large variation in the curvature of the sizing roller, during the grinding process, the protruding parts of the outer surface of the sizing roller are easily over-ground, while the concave parts are not thoroughly ground, thus affecting the grinding effect and the quality of the finished sizing roller.

[0004] Therefore, it is necessary to propose an improved grinding device for sizing roll processing to overcome the shortcomings of the existing technology. Utility Model Content

[0005] The purpose of this invention is to solve the problems in the prior art and provide a grinding device for sizing roller processing.

[0021] To make the technical means, technical features, utility model purpose and technical effects of this utility model easier to understand, the present utility model will be further described below with reference to specific illustrations.

[0022] like Figure 1 and Figure 2As shown, a grinding device for sizing roller processing includes a base 1, a column 2, a lifting mechanism, a linear module 7, a clamping mechanism, and a grinding mechanism. The column 2 is mounted on the base 1. The lifting mechanism and the grinding mechanism are both connected to the column 2. The grinding mechanism is located at the upper end of the side wall of the column 2 facing the middle of the base 1. The linear module 7 is connected to the lifting mechanism and is driven by the lifting mechanism to achieve up-and-down lifting movement. The clamping mechanism is installed at the output end of the linear module 7 and is driven by the linear module 7 to achieve reciprocating lateral movement in the left-right direction. The clamping mechanism can clamp and position the sizing roller and drive the sizing roller to rotate. During the rotation of the sizing roller, the lifting mechanism and the linear module 7 can drive the sizing roller to move up, down, left, and right. The grinding mechanism completes the grinding operation of the sizing roller according to its shape.

[0023] like Figure 1 and Figure 2 As shown, the lifting mechanism includes a lifting motor 3 and a lifting screw 4. The lifting motor 3 is installed at the top of the column 2, and the lifting screw 4 is connected to the column 2. The lifting motor 3 and the lifting screw 4 are connected by a transmission. The lifting motor 3 drives the lifting screw 4 to rotate relative to the column 2. A lifting seat 5 is threadedly connected to the lifting screw 4 for the installation of the linear module 7. A first guide groove 6 is machined on the side wall of the column 2. The lifting seat 5 passes through and is connected in the first guide groove 6 and can slide up and down along the first guide groove 6. Since the lifting seat 5 is threadedly connected to the lifting screw 4, the rotational motion of the lifting screw 4 can be converted into the up and down movement of the lifting seat 5. The first guide groove 6 limits and guides the up and down movement of the lifting seat 5.

[0024] like Figure 1 and Figure 2 As shown, the clamping mechanism includes a slotted plate 8, a first clamping seat 9, a second clamping seat 10, a forward and reverse threaded screw 11, and a drive motor 12. The slotted plate 8 is connected to the output end of the linear module 7 through a heightening seat 13. A limiting groove is machined on the surface of the slotted plate 8 facing away from the heightening seat 13. The limiting groove adopts a T-shaped groove or a dovetail groove structure. There are two limiting grooves, which are distributed parallel to each other along the length of the slotted plate 8. The first clamping seat 9 and the second clamping seat 10 are installed opposite to each other. Both the first clamping seat 9 and the second clamping seat 10 can slide within the limiting groove.

[0025] Both the positive and negative threaded screws 11 and the drive motor 12 are mounted on the surface of the slot plate 8 facing away from the limiting groove. The drive motor 12 is mounted at one end of the slot plate 8. The positive and negative threaded screws 11 are rotatably connected to the slot plate 8. The drive motor 12 is connected to the positive and negative threaded screws 11 for transmission. The drive motor 12 drives the positive and negative threaded screws 11 to rotate. A drive seat 14 is threaded to each end of the positive and negative threaded screws 11. The two drive seats 14 are respectively connected to the first clamping seat 9 and the second clamping seat 10. A second guide groove 22 is machined on the slot plate 8. The second guide groove 22 is located between the two limiting grooves. Both drive seats 14 are connected through the second guide groove 22 and slide along the second guide groove 22 under the drive of the positive and negative threaded screws 11. The second guide groove 22 guides and limits the sliding of the drive seats 14.

[0026] A first bearing seat 15 is machined on the outer wall of the first clamping seat 9, and a first clamping arm 16 is connected inside the first bearing seat 15. A second bearing seat 17 is machined on the outer wall of the second clamping seat 10, and a second clamping arm 18 is connected inside the second bearing seat 17. A rotary motor 19 is also installed on the outer wall of the second clamping seat 10. The rotary motor 19 and the second clamping arm 18 are connected by a drive. The drive is a conventional drive. In this embodiment, a gear drive is used as an example. Specifically, a drive gear 20 is fixedly connected to the output shaft of the rotary motor 19, and a driven gear 21 is fixedly connected to the second clamping arm 18. The drive gear 20 and the driven gear 21 mesh. The first clamping arm 16 and the second clamping arm 18 are both machined into a tapered structure, which can be inserted into the central through hole of the sizing roller and can adapt to the clamping needs of multi-specification positioning rollers. The diameter of the driven gear 21 is larger than the diameter of the drive gear 20, which can realize the deceleration drive.

[0027] The drive motor 12 drives the forward and reverse threaded screws 11 to bring the first clamping seat 9 and the second clamping seat 10 closer together, clamping and positioning the sizing roller between the first clamping arm 16 and the second clamping arm 18. The rotary motor 19 drives the drive gear 20 to rotate. Through the meshing of the drive gear 20 and the driven gear 21, the second clamping arm 18 is driven to rotate within the second bearing seat 17. Due to the force between the first clamping arm 16 and the second clamping arm 18, the sizing roller and the first clamping arm 16 can be driven to rotate.

[0028] like Figure 1 and Figure 2As shown, the grinding mechanism includes a cantilever 23, connecting rods 24, mounting plate 25, and abrasive blocks 26. The cantilever 23 is connected to the upper end of the side wall of the column 2 facing the center of the base 1. There are two connecting rods 24, which are connected through the cantilever 23. A guide sleeve 28 is installed at the position where the connecting rod 24 passes through the cantilever 23. The connecting rod 24 is slidably connected in the guide sleeve 28, which guides the sliding of the connecting rod 24 and reduces friction. The mounting plate 25 is connected to the lower end of the two connecting rods 24 and is used to install the abrasive blocks 26. The abrasive blocks 26 are detachably connected to the mounting plate 25 for easy replacement. A spring 27 is fitted on the connecting rod 24. One end of the spring 27 abuts against the cantilever 23, and the other end of the spring 27 abuts against the mounting plate 25. When the abrasive block 26 comes into contact with the sizing roller, it can float by compressing the spring 27 to avoid hard contact and over-grinding.

[0029] like Figure 1 and Figure 2 As shown, a receiving groove 29 is installed on the base 1. After the sizing roller is clamped and positioned, the receiving groove 29 is located below the sizing roller. The grinding debris falls downward into the receiving groove 29, avoiding splashing everywhere and causing environmental pollution, and facilitating unified collection and treatment.

[0030] The working principle of this utility model is as follows:

[0031] In use, the sizing roller is manually held or hoisted and placed between the first clamping seat 9 and the second clamping seat 10. The drive motor 12 is started, and the drive motor 12 drives the first clamping seat 9 and the second clamping seat 10 to move closer together through the positive and negative threaded screws 11, so that the first clamping arm 16 and the second clamping arm 18 are respectively inserted into the center holes at both ends of the sizing roller to clamp and fix the sizing roller. The lifting motor 3 is started, and the lifting motor 3 drives the sizing roller to move closer to the abrasive block 26 through the lifting screw 4, so that the abrasive block 26 contacts the surface of the sizing roller. The rotary motor 19 is started, and the rotary motor 19 drives the sizing roller to rotate. During the rotation, the lifting motor 3 drives the lifting screw 4 to move the sizing roller up and down, and the linear module 7 drives the sizing roller to move left and right, so that the curved surface of the sizing roller maintains appropriate contact and fit with the abrasive block 26, so as to achieve grinding of the sizing roller. Through the compression of the spring 27, the height difference of the curved surface of the sizing roller is prevented from being in excessive contact with the abrasive block 26 for a long time, which would cause over-grinding, thus ensuring the grinding effect and improving the quality of the finished sizing roller.

[0032] The above description is merely a preferred embodiment of this utility model and is not intended to limit the scope of this utility model. All equivalent changes and modifications made in accordance with the scope of the claims of this utility model should fall within the technical scope of this utility model.
