Description

Technical Field

[0001] The utility model relates to the technical field related to mechanical processing, and in particular to a high-precision roller leveling mechanism. Background Art

[0002] Before machining, the roller requires clamping to stabilize and center the workpiece. Traditional lathes utilize a three-jaw chuck on one side and a centering tool on the other, making this structure suitable for smaller, shorter workpieces. However, roller laser engraving machines process workpieces up to approximately 6 meters in length. To prevent axial bending of the roller, a centering tool and three-jaw chucks are used on both sides. Furthermore, because the workpieces can weigh several tons, they must be hoisted using a crane, resulting in low handling accuracy. Furthermore, the heavy weight can cause the workpiece to bend downward. Consequently, high precision is required for the workpiece's center position before clamping, necessitating a supplementary support method.

[0003] Currently, roller clamping is mostly done by manual handling or overhead crane. Manual handling has the advantage of being able to handle workpieces of various sizes, but these are usually small products. Overhead cranes have the advantage of being able to handle large workpieces, but the clamping accuracy is low and they can only accommodate products with small diameter differences.

[0004] In view of the above-mentioned defects, the designers have actively carried out research and innovation in order to create a high-precision roller leveling mechanism to make it more valuable for industrial use. Utility Model Content

[0029] In order to enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. The components of the embodiments of the present invention generally described and shown in the drawings here can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of the present invention provided in the drawings is not intended to limit the scope of the utility model for which protection is sought, but merely represents selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without making creative work are within the scope of protection of the present invention.

[0030] like Figures 1 to 4 As shown, a high-precision roller leveling mechanism includes a roller lifting base 1 and a roller lifting top seat 4 from top to bottom, a roller lifting support assembly 5 is installed on the roller lifting top seat 4, and the roller lifting module installed on the roller lifting base 1 drives the upper roller lifting top seat 4 to move in the vertical direction.

[0031] 1. The drum lifting module includes a servo motor 8, a reducer 9 and a worm gear screw lift 13 respectively installed on the drum lifting base 1. The servo motor 8 is connected to the input end of the reducer 9 at the rear end, and the output end of the reducer 9 is connected to the worm gear screw lifts 13 on the left and right sides through the coupling 14. The worm gear screw lift 13 drives the upper drum lifting base 4 to move in the vertical direction.

[0032] 2. A laser sensor 7 is installed on the outer front end of the roller lifting base 1 through a sensor bracket 6.

[0033] 3. The roller lifting support assembly 5 includes a support base 16 installed on the roller lifting top base 4, and a roller mounting groove 17 distributed along the left and right directions is opened on the inner side of the top of the support base 16. Support rollers 18 are installed on the left and right sides of the roller mounting groove 17, and a V-shaped groove 19 is opened on the roller mounting groove 17 between the two support rollers 18.

[0034] The support roller 18 is installed in the roller mounting groove 17 through the roller mounting shaft 20 distributed along the front and rear directions. The rear end of the roller mounting shaft 20 is installed in the roller mounting groove 17 through the retaining ring 21, and the roller mounting shaft 20 at the front and rear ends of the support roller 18 is installed with a spacer 22.

[0035] 4. A roller lifting fixing plate 3 is provided between the roller lifting base 1 and the roller lifting top seat 4. The roller lifting fixing plate 3 is mounted on the roller lifting base 1 via a plurality of roller lifting struts 2. A plurality of guide posts 15 distributed along the vertical direction are mounted on the roller lifting fixing plate 3. The roller lifting top seat 4 is connected to the guide posts 15.

[0036] 5. A sensor stand 10 is installed on one of the roller lifting pillars 2, and a number of photoelectric sensors 11 are evenly distributed along the vertical direction on the sensor stand 10. At the bottom of the roller lifting top seat 4, a sensor sheet 12 distributed along the vertical direction and compatible with the above-mentioned photoelectric sensors 11 is installed.

[0037] Servo motor 8, as the power source, is installed on the input end of reducer 9. The output end of reducer 9 is connected to worm gear screw elevator 13 through coupling 14, so that the left and right sides can rise and fall synchronously, thereby driving the drum lifting support assembly 5 to rise and fall. Laser sensor 7 is used for distance measurement.

[0038] During use, the present invention is provided with a set of roller leveling mechanisms on both sides of the workpiece. First, the laser sensors 7 on both sides respectively measure the distance of the clamping part of the workpiece. If the measured data is different from the preset parameters, the servo motor 8 drives the worm screw elevator 13 and drives the roller lifting support assembly 5 to lift and lower, so that the left and right ends of the workpiece can be lifted and lowered in the same direction or opposite directions, respectively, to achieve the purpose of leveling it and making it equal to the center of the chuck. In addition, due to its large deadweight, long workpieces will produce downward bending deformation, and the closer to the center, the more serious it is. In order to meet high-precision processing indicators, this leveling mechanism adopts a roller lifting support assembly 5 (whose supporting part is two freely rotatable shaft parts, namely support rollers 18), which can move to a suitable position below the workpiece to serve as auxiliary support during the processing.

[0039] This new model uses a laser sensor in conjunction with a servo motor and multi-stage reduction gears to accurately ensure the center height of workpieces of varying weights, lengths, and diameters. It also serves as an auxiliary support structure during machining, meeting high-precision machining specifications.

[0040] The installed laser sensor is used to measure the level of the roller, and then the left and right center heights of the workpiece are adjusted according to the measured value to ensure that it is at the same height as the center of the chuck.

[0041] The roller lifting module can not only adapt to a variety of workpieces with different diameters, but also act as a support seat during the processing of long rollers.
