Description

Technical Field

[0001] This utility model relates to the field of mechanical processing equipment technology, and in particular to a grinding device for the tip of a CNC roll grinding machine. Background Technology

[0002] In modern industrial production, the roll is an important component of the rolling mill, and its quality directly affects the production quality and efficiency of steel. During long-term use, the precision of the roll tip will decrease due to factors such as wear and oxidation, and it needs to be polished and repaired regularly. However, many problems still exist in practical applications.

[0003] Traditional fixed structures are difficult to adapt quickly and accurately to rolls of different sizes, resulting in poor versatility. Furthermore, once fixed, the rolls cannot rotate flexibly, hindering all-around grinding. The position adjustment of the grinding equipment is not precise enough to meet high-precision grinding requirements. The grinding and polishing functions are limited, making it difficult to handle complex grinding tasks, leading to low grinding efficiency. Moreover, the lack of effective debris removal and cooling measures means that debris accumulation and high temperatures during grinding affect grinding quality and increase equipment wear. Therefore, we have introduced a tip grinding device for CNC roll grinding machines. Utility Model Content

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0027] Please see Figure 1-4 This utility model provides a technical solution:

[0028] A CNC roll grinding machine tip grinding device includes a processing table 1. The upper front part and the upper rear part of the processing table 1 are respectively provided with a displacement groove 3 and a displacement groove 4. The right front part and the right rear part of the processing table 1 are respectively fixedly connected with a fixing device 6 and a grinding equipment device 5. The left end of the processing table 1 is fixedly connected with a water tank 2.

[0029] In this embodiment, the fixing device 6 includes a first drive motor 61 and a second drive motor 64. The output end of the first drive motor 61 passes through the processing table 1 and is fixedly connected to a threaded rod 62. Displacement plates 63 are movably connected to the left and right sides of the outer surface of the threaded rod 62. The output end of the second drive motor 64 passes through the left displacement plate 63 and is fixedly connected to a left clamping block 65. A connecting shaft 68 is movably mounted on the upper left end of the right displacement plate 63 via a bearing. A right clamping block 67 is fixedly connected to the left end of the connecting shaft 68. Clamping grooves 66 are opened at the middle of the right end of block 65 and the middle of the left end of right clamping block 67.

[0030] The above scheme involves placing the roll to be ground on the processing table 1, then starting drive motor 61. Its output drives the positive and negative threaded rod 62 to rotate. Because the threads on the left and right sides of the positive and negative threaded rod 62 are opposite, the two displacement plates 63, which are movably connected to its outer surface, slide towards or away from each other in the displacement groove 3, thereby adjusting the distance between the left clamping block 65 and the right clamping block 67. When the distance is suitable for the roll size, drive motor 64 is started. Its output drives the left clamping block 65 to rotate, which, together with the right clamping block 67, firmly clamps the roll through the clamping groove 66. Under the action of drive motor 64, the roll can be driven to rotate, providing a stable fixed foundation for subsequent grinding. The two identical and symmetrically distributed displacement plates 63, along with the left clamping block 65 and the right clamping block 67, and the transmission of the positive and negative threaded rod 62, can quickly and accurately adapt to the fixing requirements of rolls of different sizes, improving the versatility of the device. Drive motor 64 drives the left clamping block 65 to rotate, allowing the roll to rotate flexibly in the fixed state, which is convenient for grinding the tip.

A cylinder 54 is fixedly installed at the middle rear end of the moving base 53. The main body assembly 58 includes a drive motor 581 and a synchronous belt 584. The output end of the drive motor 581 passes through the side plate 57 and is fixedly connected to a pulley 582. The pulley 582 is connected to the same...

The left end of the rear fixed shaft 585 is movably connected to the right end of the connecting housing 55 via a bearing, and the right end of the front fixed shaft 585 is connected to... The right side plate 57 is movably connected to the side plate wall. The left end of the main rod 586 is movably connected to the left side plate wall of the connecting shell 55 via a bearing.

The bottom of the moving seat 53 is slidably connected in the displacement groove 4.

[0032] Through the above scheme: after the rolls are fixed, drive motor 3 51 is started, and its output end drives the long screw 52 to rotate, causing the movable seat 53, which is movably connected to the outer surface of the long screw 52, ​​to move left and right within the displacement groove 2 4, thereby adjusting the lateral position of the grinding equipment. Then, cylinder 54 is started, and its output end pushes the connecting shell 55 and its components closer to or away from the rolls, realizing the longitudinal feed of the grinding equipment.

Drive motor 4 581 is started, and its output end drives the pulley 1 58. 2. The first pulley 582 is connected to the second pulley 583 via the synchronous belt 584, causing the fixed shaft 585 on the two pulleys to rotate. At the same time, the synchronous belt 584 drives the main rod 586 to rotate, causing the polishing disc 587 and grinding disc 588 on the main rod 586 to rotate at high speed, grinding and polishing the tip of the roll. During the grinding process, the micro water pump 511 is started, and the coolant in the water tank 2 is sprayed out from the nozzle 512 at a 20-degree angle through the telescopic pipe 510 to cool and rinse the grinding part, preventing debris accumulation and high temperature from affecting the grinding effect.

[0033] It should be noted that this utility model is a tip grinding device for a CNC roll grinding machine. During use, the roll to be ground is first placed on the processing table 1 and fixed by the fixing device 6. The drive motor 61 is started, and its output drives the positive and negative threaded rod 62 to rotate. Since the left and right threads on the outer surface of the positive and negative threaded rod 62 are in opposite directions, the two displacement plates 63 will slide towards or away from each other in the displacement groove 3, thereby adjusting the distance between the left clamping block 65 and the right clamping block 67. When the distance is appropriate, the drive motor 64 is started, and its output drives the left clamping block 65 to rotate. Together with the right clamping block 67, the roll is firmly clamped by the clamping groove 66 and can be rotated. After fixing the roll, the grinding operation begins.
