Description

Technical Field

[0001] The utility model relates to the field of rubber roller production, in particular to a drilling device based on adjusting the dynamic balance of a rubber roller. Background Art

[0002] Rubber rollers are cylindrical objects made of rubber materials. Their diameters are usually between tens of millimeters and one meter, and their lengths are between tens of centimeters and several meters. According to different usage scenarios and functional requirements, rubber rollers can be divided into many types, such as electrical insulation rubber rollers, rubber rollers for plastic processing, rubber rollers for rubber processing, rubber rollers for printing, etc., as well as special rubber rollers for various industries such as steel, mining, chemical, textile, papermaking, and medicine.

[0003] After the rubber roller is turned, there will be certain welding and processing errors between its outer cylindrical surface and the center of the connecting shafts at both ends. At this time, when the rubber roller rotates at high speed, the thicker wall side will produce a larger centrifugal force, which can easily cause the roller to deform, thus affecting its use effect and life. For this reason, during production design, holes are usually drilled on the end face of the rubber roller near the thinner wall area, and rod-shaped counterweights are added to indirectly achieve the counterweight effect and balance the force on its outer cylindrical surface.

[0004] With respect to the above-mentioned related technologies, the inventors found that the traditional drilling method is that the staff uses a drill gun to directly drill holes in one end of the rubber roller close to the outer cylindrical surface. Since the hole diameters required to be drilled are different, it is difficult to ensure the verticality and straightness of the drilling during manual operation, which may cause the position of the hole to deviate from the predetermined position or the straightness of the hole to fail to meet the standard, which not only affects the drilling efficiency and accuracy, but also affects the subsequent installation of the counterweight block. Utility Model Content

[0005] The main technical problem solved by the utility model is to provide a drilling device based on adjusting the dynamic balance of a rubber roller, thereby improving the efficiency and accuracy of drilling and facilitating the installation of a counterweight block.

[0006] In order to solve the above technical problems, a technical solution adopted by the utility model is: to provide a drilling device based on adjusting the dynamic balance of a rubber roller, comprising: a workbench and a roller positioning mechanism installed on the top thereof, one side of the roller positioning mechanism is connected to a drilling mechanism, the drilling mechanism comprises a mounting seat and a connecting plate connected to one side thereof, a side of the connecting plate close to the roller positioning mechanism is slidably connected to a drilling assembly, and also comprises a driving assembly for driving the drilling assembly to move;

[0008] By adopting the above technical solution, the combination of gears and racks provides a precise transmission mechanism, which can ensure that the drilling position of the drilling assembly at the end of the rubber roller is accurate. Compared with manual operation, the automatic drilling system driven by gears and racks can work continuously and stably without human intervention, thereby improving the drilling efficiency. At the same time, the roller positioning mechanism can position the rubber roller and effectively fix it when drilling.
