Description

Technical Field

[0001] This utility model relates to the field of grinding machine technology, specifically to a grinding machine repair roller neck grinding adjustment device. Background Technology

[0002] Roll grinding machines are an indispensable piece of production equipment in modern industrial manufacturing. Rolls are mainly used in industries such as metallurgy and papermaking. While their grinding mechanism shares characteristics with general large cylindrical grinding machines, it differs significantly in its complexity. In addition to the relative rotational motion (main motion) between the grinding wheel and the workpiece (roll), it requires both the grinding wheel and workpiece to perform relative longitudinal motion while simultaneously undergoing a certain radial relative displacement. Moreover, this radial displacement is a composite motion distinct from the grinding taper. Therefore, its transmission mechanism is more complex, and the machine tool requires higher precision. Its grinding mechanism shares characteristics with general large cylindrical grinding machines. In recent years, grinding machine processing has seen significant development and has been widely applied in the machining industry. Grinded mechanical parts achieve high precision and very fine surface roughness.

[0003] When the workpiece to be ground has a large grinding allowance, the existing operation method is to first clamp the workpiece on a lathe for turning, and then clamp the workpiece on a grinding machine for grinding. The two processes require clamping twice, which is not only inconvenient to operate, but also affects the machining accuracy. Utility Model Content

Detailed Implementation

[0022] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0023] Please see Figure 1-6 As shown, a grinding adjustment device for repairing grinding roller necks on a grinding machine includes a base 1 and a support frame 2, fixedly connected to the top of the base 1. A guide rail 3 is mounted on the support frame 2 and can move on the support frame 2. A hydraulic rod 4 is fixedly connected to the guide rail 3, and a bracket 5 is fixedly connected to the piston rod of the hydraulic rod 4. A roller 6 is mounted on the bracket 5, and the roller 6 includes a roller neck 601 mounted on the bracket 5. A roller body 602 is fixedly connected to the roller neck 601. The bracket 5 supports and limits the roller 6 on the guide rail 3, and the height of the bracket 5 and the roller 6 is adjusted by the hydraulic rod 4. A transmission assembly 7 is also included. Mounted on the top of the base 1, the transmission assembly 7 drives the rolling guide rail 3 and the rolling roller 6 to move on the support frame 2. The transmission assembly 7 includes a servo motor 701 mounted on the base 1. The output end of the servo motor 701 is fixedly connected to a drive gear 702. A driven gear 703 meshes with the drive gear 702. Half gears 704 are fixedly connected to both the drive gear 702 and the driven gear 703. A transmission gear 705 meshes with the half gear 704. A moving gear 706 is fixedly connected to the transmission gear 705. A toothed plate 707 that meshes with the moving gear 706 is fixedly connected to the bottom of the guide rail 3.

[0024] It should be noted that during operation, the hydraulic rod 4 is used to drive the bracket 5 to lift the roll neck 601 of the roll 6 to a suitable position, ensuring that it is horizontal with the other end of the roll 6, so that the grinding head and grinding wheel of the machine tool can directly act on the roll 6 to perform grinding treatment on the roll 6.

[0025] Two hydraulic rods 4 are symmetrically arranged, and each piston rod is fixedly connected to a bracket 5; a bearing 11 is fixedly connected to the bracket 5; in this application, the hydraulic rod 4 is only used as an actuator, and the selection and connection method of its power assembly (such as a hydraulic pump) are conventional designs that can be directly determined by those skilled in the art based on load requirements. The bearing 11 is adapted to the roll 6 to be processed, limiting the roll 6 on the bracket 5. The hydraulic rod 4 is used to drive the bracket 5 and the roll 6 to rise and fall, adjusting the distance between the roll 6 and the machine tool grinding wheel.

[0026] The transmission assembly 7 includes a servo motor 701 mounted on the base 1. A drive gear 702 is fixedly connected to the output end of the servo motor 701. A driven gear 703 meshes with the drive gear 702. Half gears 704 are fixedly connected to both the drive gear 702 and the driven gear 703. A transmission gear 705 meshes with the half gears 704. A moving gear 706 is fixedly connected to the transmission gear 705. A toothed plate 707 meshes with the moving gear 706 and is fixedly connected to the bottom of the guide rail 3. A support plate 8 is fixedly connected to the base 1, and the servo motor 701 is fixedly connected to the support plate 8. The driven gear 703 and the transmission gear... All wheels 705 are rotatably connected to the support plate 8. During operation, the servo motor 701 drives the drive gear 702 to rotate, which in turn drives the driven gear 703 to rotate. The drive gear 702 and the driven gear 703 drive their outer half gears 704 to rotate synchronously. The two half gears 704 are installed in a staggered manner. When one of them meshes with the transmission gear 705, the other disengages from the transmission gear 705. The two half gears 704 mesh with the transmission gear 705 at intervals. Since the two half gears 704 rotate in opposite directions, the moving gear 706 meshes with the toothed plate 707, driving the guide rail 3 to reciprocate.

[0027] A support base 9 is fixedly connected to the support frame 2, and a limit block 10 is fixedly connected to the bottom of the guide rail 3. The limit block 10 slides in the support base 9 to limit the guide rail 3 on the support frame 2.

[0028] Working principle: The roll 6 is installed on the bracket 5. The hydraulic rod 4 drives the bracket 5 to lift the roll neck 601 of the roll 6 to a suitable position, ensuring that it is horizontal with the other end of the roll 6. This allows the grinding head and grinding wheel of the machine tool to directly act on the roll 6 for grinding. When the roll grinding machine is performing ultra-precision grinding, selecting a better feed rate can ensure grinding accuracy. For surface roughness requirements, the grinding parameters are generally selected based on experience. Generally, the transverse feed is about 5 micrometers, and the longitudinal grinding parameters are 0.3-0.5 meters / minute. When precision grinding rolls, the machine tool should be idle for 30 minutes to allow the machine tool to reach thermal equilibrium and for the hydraulic oil to purge static air before grinding. The large amount of grinding heat will soften the workpiece surface, increasing its elasticity and facilitating grinding. However, this has adverse effects on the roll surface quality, the abrasive, and the machine tool, impacting the machine tool's accuracy. For high-precision rolls, during no-feed finishing grinding, the roll speed can be continuously varied within a slow range while grinding to reduce or disrupt the impact of various machine tool vibration frequencies on grinding roundness and grinding ripples, thus improving the roll grinding quality. Thanks to the adoption of many new technologies and designs mentioned above, modern roll grinding machines can basically meet the needs of steel rolling technology development.
