Description

Technical Field

[0001] The utility model relates to the technical field of roll maintenance, in particular to a roll grinding and adjusting device. Background Art

[0002] Roll grinding machines are mainly used for the repair, grinding and polishing of rolls. Rolls are commonly used tools in the metal processing process, used to plastically deform materials such as metal blocks or plates in rolling mills. Due to long-term use or wear during use, problems such as wear, dents, and cracks may occur on the surface of the roll. These problems will affect the rolling quality and processing efficiency. Therefore, in order to restore the surface quality of the roll, a roll grinding machine is needed for repair and grinding. Currently, the roll grinding machine mainly includes a driving mechanism for driving the roll to rotate, a supporting mechanism for supporting the roll, and a grinding block in contact with the working surface of the roll. The driving mechanism clamps one end of the roll through a chuck, and then drives the chuck to drive the roll to rotate through a reduction motor. When the roll rotates, the grinding block approaches the roll for grinding, and then the grinding block moves along the axial direction of the roll, so that the entire working surface of the roll can be ground. Among them, when the roll is installed, generally a hoisting device is used to place the roll on the supporting mechanism. However, during the hoisting process, the roll is prone to shaking. The supporting mechanism can position the roll laterally through an arc surface, but cannot position the roll axially. The axial moving stroke of the grinding block has been set. If the roll is axially offset during placement, it will cause one end working surface of the roll not to contact the grinding block during grinding, affecting the grinding quality. Only by extending the axial moving stroke of the grinding block to adapt to the shaking range of the roll, however, the axial moving speed of the grinding block is slow. This method will not only cause waste of energy, but also delay the grinding time. Content of the Utility Model

[0003] The purpose of the utility model is to avoid the deficiencies of the prior art and provide a roll grinding and adjusting device, thereby effectively solving the deficiencies existing in the prior art.

[0004] To achieve the above purpose, the technical solution adopted by the utility model is: a roll grinding and adjusting device, including two support frames arranged at both ends of the roll, a cross plate is arranged between the two support frames, a moving frame and a first driving device for driving the moving frame to move along the axial direction of the roll are arranged on the cross plate, a moving block and a second driving device for driving the moving block to move along the axial direction of the roll are arranged on the moving frame, a grinding block and a third driving device for driving the grinding block to move vertically are arranged on the moving block, and a positioning rod that can abut against the end face of the roll is arranged on the moving frame.

[0005] Further, a roller is arranged on the positioning rod, and the roller is arranged along the tangential direction of the roll.

[0006] Further, the positioning rod is hinged to the moving frame. An elastic member tending to force the positioning rod to rotate towards one side of the roll is provided at the hinge of the positioning rod. A limiting mechanism for limiting the rotation angle of the positioning rod towards one side of the roll is provided on the moving frame. A stop block is provided on the moving frame on the side of the positioning rod away from the roll. A sensor for controlling the operation of the first driving device is provided on the stop block.

[0007] Further, the limiting mechanism is a limiting groove provided on the lower side of the stop block. A limiting rod extending into the limiting groove is provided at the bottom of the positioning rod, and there is a gap between the top surface of the limiting groove and the limiting rod.

[0008] Further, the upper end of the support frame is arc-shaped, and a plurality of rotating shafts are arranged along the circumference on the inner surface of the arc.

[0009] The above technical solution of the present utility model has the following beneficial effects: After the roll is placed on the support frame, the moving frame can be driven to move by the first driving device. The moving frame is positioned by the positioning rod abutting against the side end face of the roll, so that the grinding block on the moving frame corresponds to the position of the roll, and the entire working surface of the roll can be ground without increasing the stroke of the grinding block, reducing the waste of time and energy caused by the unnecessary slow movement of the grinding block.
