Description

Technical Field

[0001] The utility model relates to the technical field of numerical control roll grinding machines, and more specifically, the utility model relates to a roll adjusting device for a numerical control roll grinding machine. Background Art

[0002] The numerical control roll grinding machine is an important supporting equipment for the steel plate rolling production line. Its grinding accuracy and grinding efficiency directly affect the rolling quality and production efficiency of the steel plate. During the steel plate rolling process, the geometric accuracy of the roll surface will be damaged due to high-temperature oxidation and mechanical wear, etc., and it is necessary to periodically grind and repair the roll surface;

[0003] The movable roll group is driven by a telescopic device to fix the roll. However, this method is likely to cause impact damage to the end of the roll during the clamping process, and the roll needs to be placed between the movable roll group and the fixed roll group with the assistance of staff, increasing the operation burden of the staff;

[0004] Chinese Patent with the patent application number CN202323213962.9 discloses a roll adjusting device for a numerical control roll grinding machine, including a machine table installed inside the workshop. A fixed roll group is installed on the left side of the upper end of the machine table, and a support plate is fixedly installed on the right side of the upper end of the machine table. For this roll adjusting device of the numerical control roll grinding machine, by driving the up and down movement of the bearing frame, the roll can be placed between the movable roll group and the fixed roll group, so that there is no need for staff to support, and fine adjustment can be realized by the cooperation of the worm and the worm wheel, avoiding impact damage to the roll;

[0005] However, it can be seen from the attached drawings of its specification that the bearing frame is supported and adjusted by two connecting rods arranged at the center position of the bottom of the bearing frame. Since the bearing frame is set in a "V" shape, it is easy to cause the bearing frame to tilt when the roll is placed on the top of the bearing frame, affecting the placement stability of the roll, and it is easy to cause the bearing frame to shake when the bearing frame moves up and down, affecting the adjustment stability of the roll.

The double-shaft motor is fixed in the middle of the support table, and the output end of the double-shaft motor is connected with a second bevel gear;

[0009] Limiting rings are symmetrically and fixedly connected to both ends of the rotating rod. Limiting sliders are symmetrically arranged on both sides of the limiting ring. The top of the limiting slider is rotatably connected with a first support rod.

[0010] Preferably, both ends of the second support rod are inclined, the bottom of the second support rod is horizontally structured, and the cross-section of the second support rod is circular.

[0011] Preferably, the connecting rod penetrates through the middle of the second support rod and is fixedly connected with a plurality of second support rods. The number of the support plates is two, and the support plates are fixed at both ends of the second support rod. The bottom wall of the support plate is horizontal.

[0012] Preferably, the side walls of the connecting rod and the support plate close to the roller are both lower than the side walls of the second support rod close to the roller. The first support rod corresponds to the connecting seat, and the top of the first support rod is rotatably connected with the connecting seat.

[0013] Preferably, the second bevel gear meshes with the first bevel gear. Threads are symmetrically arranged on the surface of the rotating rod at both sides of the limiting ring.

[0015] The technical effects and advantages of the present utility model:

[0016] 1. First, the present utility model is supported by a plurality of first support rods around the bottom of both sides of the support frame, which can improve the support stability of the support frame. And through the simultaneous movement of a plurality of first support rods, the stability of the up-and-down movement of the support frame can be improved, thereby improving the stability of the up-and-down movement of the roller, improving the adjustment and support stability of the roller, improving the use effect. And by starting the double-shaft motor to control the second bevel gear to drive the first bevel gear to make the two rotating rods rotate simultaneously, the driving stability can be improved and the use effect can be improved;

[0017] 2. The utility model also improves the connection stability of multiple second support rods through the cooperation of the connecting rod and the support plate. By setting the side walls of the connecting rod and the support plate close to the roller lower than the side walls of the second support rods close to the roller, when the roller is placed inside the support frame, it only contacts the side walls of the second support rods, which facilitates the horizontal movement of the roller and will not cause abrasion to the roller, improving the use effect. The set limit ring can limit the moving position of the limit slider, facilitating use;

[0018] In summary, through the mutual influence of the above multiple functions, multiple first support rods can support the support frame simultaneously, improving the stability of the up-and-down movement of the support frame, thereby enhancing the stability of the support adjustment of the roller and improving the use effect.
