[0027] The present invention is further described below by way of embodiments in conjunction with the accompanying drawings.

[0028] like Figure 1-Figure 5 As shown, a roller surface drilling device includes a drilling machine body 4, a bearing component 1 that can be installed on the workbench of the drilling machine body 4, and supporting components 2 that can fix rollers of various sizes and types to be drilled and enable them to rotate are arranged on both sides of the bearing component 1, and a driving component 3 that can rotate the fixed roller to a certain angle according to the drilling needs is arranged above the bearing component 1.

[0029] In this embodiment: the supporting component 1 includes a base 101, to which a guide rail 102 is fixedly connected; the base 101 provides an installation position for the guide rail 102 for installing the carrier 202 and some components of the supporting component 2 and the driving component 3, and the guide rail 102 limits the movable range of the carrier 202 in this device.

[0030] In this embodiment, the support assembly 2 includes a transverse moving part that can adapt to various sizes of rollers to be drilled, a rolling part that can prevent the roller from being damaged due to friction when rotating, and a clamping part that can effectively fix the roller so that it can rotate. The transverse moving part includes a horizontal double-rod hydraulic cylinder 201 fixedly installed in the bearing assembly 1, and the telescopic end of the horizontal double-rod hydraulic cylinder 201 is fixedly connected to a carrier 202. The rolling part includes an arc frame 203 fixedly connected to the carrier 202, and the arc frame 203 is movable. A rotating rod 204 is installed, and the clamping member includes a support 205 fixedly installed in the carrier 202, and a vertical hydraulic cylinder 206 is movably connected to the support 205. A roller frame 207 is fixedly connected to the telescopic end of the vertical hydraulic cylinder 206, and a rubber-coated pressure roller 208 is movably installed in the roller frame 207. The clamping member also includes a longitudinal double-rod hydraulic cylinder 209 fixedly installed in the carrier 202, and a connecting rod 210 is movably connected between the telescopic end of the vertical hydraulic cylinder 206 and the adjacent longitudinal double-rod hydraulic cylinder 209;

[0031] The guide rail 102 is slidably connected to the carrier 202, the arc frame 203 is rotatably connected to the rotating rod 204, the support 205 is rotatably connected to the vertical hydraulic cylinder 206, the roller frame 207 is rotatably connected to the rubber-coated pressure roller 208, and the vertical hydraulic cylinder 206 and the longitudinal double-rod hydraulic cylinder 209 are both rotatably connected to the connecting rod 210;

[0032] The carrier 202 is driven to slide relative to the guide rail 102 by the horizontal double-rod hydraulic cylinder 201, so that the distance between the two carriers 202 can be changed according to the length of the roll to be drilled. The roll is supported by the carrier 202, and the moving range of the roll is limited by its own arc after contacting the roll. The rotating rod 204 is fixed on the carrier 202 by the arc frame 203, so that the rotating rod 204, which can rotate relative to the arc frame 203, can contact the roll instead of the carrier 202, so as to avoid the roll from being damaged due to friction with the carrier 202 when rotating. The vertically fixed support 205 The position of the lower end of the hydraulic cylinder 206 is transmitted to the rubber-coated pressure roller 208 through the roller frame 207 to change the length of the telescopic end of the vertical hydraulic cylinder 206, so that the height of the rubber-coated pressure roller 208 is adjustable. The length change of the telescopic end of the longitudinal double-rod hydraulic cylinder 209 is transmitted to the vertical hydraulic cylinder 206 through the connecting rod 210 to change the inclination of the vertical hydraulic cylinder 206, thereby changing the longitudinal position and height of the rubber-coated pressure roller 208. The rubber-coated pressure roller 208 with adjustable height and longitudinal position is used to press the roller obliquely downward, thereby preventing the roller from moving in the device without affecting the rotation of the roller.

[0033] In this embodiment: the driving assembly 3 includes a roller seat 301 fixedly connected to the upper side of the base 101, a rubber-coated roller 302 is movably connected between the roller seats 301, one end of the rubber-coated roller 302 is fixedly connected to a first pulley 303, a motor 304 is fixedly installed in the base 101, a second pulley 305 is fixedly connected to the output end of the motor 304, and a belt 306 is provided between the first pulley 303 and the second pulley 305; the roller seat 301 is rotatably connected to the rubber-coated roller 302;

[0034] The rubber-coated roller 302 is installed at a certain height above the base 101 through the roller seat 301, and the roller to be drilled placed between the carriers 202 is appropriately lifted from the bottom by the rubber-coated roller 302. The rotation of the output end of the motor 304 is transmitted to the rubber-coated roller 302 through the second pulley 305, the belt 306, and the first pulley 303, so that the rubber-coated roller 302 that can contact the roller can drive the roller to rotate a certain angle after its own rotation.

[0035] Working principle: When drilling holes on the surface of a metallurgical roll, according to the length of the roll to be drilled, the distance between the two carriers 202 is adjusted in advance through the operation of the horizontal double-rod hydraulic cylinder 201, so that the distance is smaller than the length of the roll body, and then the roll is horizontally centered and suspended between the carriers 202 so that the roll body contacts the rotating rod 204. After the roll is stabilized on the carrier 202, the vertical hydraulic cylinder 206 and the longitudinal double-rod hydraulic cylinder 209 can be used to work together to allow each rubber-coated pressure roller 208 to rise from the carrier 202, and then the roll is fully limited by pressing the roll obliquely downward, and then the roll surface can be drilled through the drilling machine body 4 as needed. If it is necessary to adjust the unobstructed part of the roll according to the drilling needs during processing, the rubber-coated rotating roller 302 can be driven by the motor 304 to rotate, so that the roll is driven by the rubber-coated rotating roller 302 below it and rotates a certain angle.
