Description

Technical Field

[0001] This utility model relates to the field of roll processing technology, specifically a roll polishing device that can be adapted to different rolls. Background Technology

[0002] Roll polishing equipment is a key piece of equipment in the steel rolling industry used for precision machining of roll surfaces. It primarily improves the surface accuracy and smoothness of rolls through grinding and polishing processes, ensuring the quality of steel rolling. Its core structure includes a polishing head, a feeding mechanism, a spindle drive system, and a CNC control system. It can handle various rolls with diameters of 200-1500mm and lengths of 3-12 meters. The equipment uses a servo motor to drive the polishing head at high speed, combined with a linear guide rail to achieve micron-level feeding. It can remove defects such as oxide scale and wear marks from the roll surface. However, existing roll polishing equipment still has certain problems in use:

[0003] For example, the technical solution of the roll polishing device with application number 202320127258.2 is as follows: it includes a roll body and a fixed block of the roll body, as well as a telescopic mechanism; a slide rail is provided at the lower end of the telescopic mechanism; two drive motors are slidably connected at the lower end of the slide rail; the output ends of the two drive motors are fixedly connected to a sanding wheel that cooperates with the roll body; a sanding belt is provided on the two sanding wheels; an electric push rod is provided on the telescopic mechanism; a slide rod is fixedly connected to the output end of the electric push rod. However, the traditional fixed clamps in the existing roll polishing devices are only designed for rolls of a single specification. When dealing with rolls with a large diameter span, it is necessary to manually replace the entire set of chucks and support components, which is time-consuming and labor-intensive. On the other hand, the collection of waste chips relies on traditional broom sweeping or inefficient dust collection devices. The metal dust and polishing paste mixture generated during the polishing process are easily diffused into the workshop environment, resulting in the dust concentration in the workshop often exceeding the standard.

[0004] In view of this, in-depth research was conducted on the above issues, which led to the creation of this case.

[0005] To address the aforementioned issues, an innovative design was implemented based on the existing roll polishing device. Utility Model Content

[0006] The purpose of this invention is to provide a roll polishing device that can be adapted to different rolls, so as to solve the problems mentioned in the background art of being unable to adapt to rolls of different diameters for fixed polishing and being unable to effectively collect waste.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A roll polishing device adaptable to different rolls includes a base, a mounting frame fixedly installed on the top of the base, and polishing heads arranged on the left and right sides of the top surface of the mounting frame. The polishing heads are driven by servo motors. A pneumatic telescopic mechanism is fixedly installed on the rear side of the upper surface of the base, and a support frame is connected to the front output end of the pneumatic telescopic mechanism. Slide rails are fixedly installed on both the left and right sides of the upper surface of the base, and the support frame is slidably connected to the slide rails. Clamping structures are provided on both the left and right sides of the support frame, and the clamping structures include lower rollers and side rollers. The lower rollers and side rollers provide a fixed clamping effect on the sides and bottoms of rolls of different diameters. A lifting block is provided inside the support frame, and the lifting block is slidably connected to the internal slide groove of the support frame. A collection box is fixedly installed in the middle of the support frame, and the collection box has a pull-out structure.

[0009] Preferably, a drive motor is fixedly installed on the right side of the support frame, and a worm gear is connected to the output end of the drive motor on the left side, with the left end of the worm gear rotatably connected to the left side of the inside of the support frame.

[0010] Using the above technical solution, the drive motor can synchronously control the rotation of the worm gears on both sides through worm gear transmission, realize dual-shaft power output, ensure that the speed of the threaded rods on both sides of the lifting block is consistent, and avoid the tilting of the roller clamping due to the lag of lifting on one side.

[0011] Preferably, the worm gear is meshed with worm wheels on both the left and right sides, and the worm wheels are rotatably connected to the bottom surface of the support frame. A threaded rod is fixedly connected above the worm wheels, and the lifting block is threadedly connected to the top of the threaded rod.

[0012] By adopting the above technical solution, the self-locking characteristics of the worm and worm wheel can fix the position of the lifting block, prevent the roller from moving up and down due to vibration during the polishing process, and improve the clamping stability.

[0013] Preferably, the bottom of the lifting block is provided with a lifting frame, and the bottom of the lifting frame is connected to an electric telescopic mechanism. The electric telescopic mechanism is fixedly installed in the middle of the bottom surface inside the support frame, and telescopic rods are fixedly installed on the left and right sides of the bottom surface inside the support frame, with the upper end of the telescopic rods connected to the bottom surface of the lifting frame.

[0014] Using the above technical solution, the electric telescopic machine can quickly adjust the initial height of the lifting block through the linkage between the lifting frame and the telescopic rod, adapting to the center positioning requirements of rolls with different diameters.

[0015] Preferably, the lifting block has inclined surfaces on its front and rear sides, and the lower roller is rotatably connected to the top of the lifting block, and clamping rods are provided on both the front and rear sides of the lifting block.

[0016] Using the above technical solution, the inclined design of the lifting block pushes the clamping rod to rotate around the hinge point, causing the side roller to fit against the side of the roll, and together with the lower roller to form a three-point clamping, which can adapt to changes in the roll diameter and distribute the clamping force evenly.

[0017] Preferably, the clamping rod is hinged in the middle to the inside of the support frame, and a side roller is rotatably connected to the upper part of the clamping rod.

[0018] Using the above technical solution, the side roller is mounted on the clamping rod through a bearing and can roll with the rotation of the roll, avoiding scratches on the surface of the roll caused by traditional rigid clamping, while allowing the roll to move slightly axially to accommodate the slight displacement during polishing.

[0019] Preferably, a filter screen is provided on the top surface of the collection box, and a vacuum cleaner is fixedly installed on the left and right sides inside the collection box.

[0020] Using the above technical solution, the vacuum cleaner in the collection box adsorbs polishing waste through the filter, improving the efficiency of metal dust collection. Combined with the pull-out structure, cleaning can be done without stopping the machine, improving the convenience of maintenance.

[0021] Compared with the prior art, the beneficial effects of this utility model are: this roll polishing equipment is adaptable to different rolls.

[0022] 1. Adaptive three-way clamping system, compatible with multiple specifications of rolls: The lower roller supports the bottom of the roll, and the side rollers elastically fit the side through the clamping rod to form a "V" clamping structure, which can automatically adapt to the diameter change of the roll without changing the clamp, thus improving the changeover efficiency. The fine adjustment and locking of the lifting block ensures that the polishing center height of rolls of different diameters is consistent, meeting the high-precision polishing requirements.

[0023] 2. High-efficiency waste collection and filtration to improve the workshop environment: The vacuum cleaner adsorbs metal dust and polishing paste generated during the polishing process in real time, and separates solid and liquid impurities through the filter screen, effectively reducing the dust concentration in the workshop. The pull-out design of the collection box makes it easy to centrally process waste, reducing the cleaning time per cleaning session and improving efficiency compared to traditional manual cleaning. At the same time, it avoids the accumulation of waste that affects equipment operation. Attached Figure Description

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Example 1

[0032] Please see Figure 1-4 This utility model provides a technical solution:

[0033] A roll polishing device adaptable to different rolls includes a base 1, a mounting frame 2 fixedly installed on the top of the base 1, and polishing heads 3 arranged on the left and right sides of the top surface of the mounting frame 2.

A threaded rod 12 is fixedly connected above the worm wheels 11. The lifting block 13 is threadedly connected to the upper part of the threaded rod 12. The drive motor 9 is driven by the worm gear 10 and can synchronously control the rotation of the worm wheels 11 on both sides to achieve dual-axis power output. This ensures that the speed of the threaded rods 12 on both sides of the lifting block 13 is consistent, avoiding the tilting of the roller clamp due to the lag of the lifting on one side. The self-locking characteristics of the worm gear 10 and the worm wheels 11 can fix the position of the lifting block 13, preventing the roller from moving up and down due to vibration during the polishing process, and improving the clamping stability.

[0035] The lifting block 13 has inclined surfaces on its front and rear sides, and the lower roller 14 is rotatably connected to the upper part of the lifting block 13.

The clamping rods 15 are hinged in the middle to the inside of the support frame 5, and the upper part of the clamping rods 15 is rotatably connected to the inside of the side rollers 16. The inclined surface design of the lifting block 13 pushes the clamping rods 15 to rotate around the hinge point, causing the side rollers 16 to fit against the side of the roll. Together with the lower rollers 14, they form a three-point clamping, which can adapt to changes in the roll diameter and distribute the clamping force evenly. The side rollers 16 are installed on the clamping rods 15 through bearings and can roll with the roll rotation, avoiding scratches on the roll surface caused by traditional rigid clamping.
