[0001] The invention relates to the technical field of core rod clamps, in particular to a core rod clamp head adjusting claw mechanism. Background Art

[0002] A rolling mill is a device that realizes the metal rolling process, and generally refers to a device that completes the entire process of rolled material production. It consists of rolls, a rolling mill arch, a bearing seat, bearings, a self-contained reel or material reeling and unreeling platform, a base, a roll adjustment device, an upper roll balancing device, and a roll changing device. The core rod clamp adjustment mechanism is an adjustment component on the rolling mill, which is mainly used to remove and replace the core rod when it is damaged.

[0003] When the core rod of the existing core rod clamp is removed and replaced when the core rod is damaged, the top rotary box needs to be moved and removed before the support column and the core rod at the bottom of the rotary box can be removed. The replacement process is time-consuming and labor-intensive. At the same time, after long-term use, when the claws of the core rod clamp are damaged, the core rod clamp is fixed to the surface of the core rod, which makes it impossible to replace and repair the claws. For this reason, the present invention provides a core rod clamp head adjustment claw mechanism. Summary of the Invention

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] 1. The core rod clamping head adjusts the claw mechanism by setting a spring, a tooth block and a connecting ring. The limit clamping plate is pressed downward to squeeze the spring, and then the connecting ring at the top of the fixed plate is rotated on the surface of the fixed shaft to make the tooth block fixedly installed on the extension plate at the bottom of the fixed plate rotate into the wall groove of the connecting block until the tooth block on the side of the extension plate engages with the tooth groove opened in the wall groove of the connecting block. The limit clamping plate spring is loosened to drive it to rebound, thereby limiting the extension plate, thereby limiting and fixing the connecting core rod and the support column, reducing the difficulty of installation and disassembly.

[0013] 2. The core rod clamping head adjusts the clamping claw mechanism by setting a limit plate, a clamping block and a clamping column, and fits the first clamping block and the second clamping block on the surface of the connecting core rod, and then slides the limit plate into the clamping groove of the first clamping block and the second clamping block to form a preliminary clamping, and then inserts the clamping column into the connecting groove through the fixing ring fixed by the fixing block on the side of the limit plate. During the insertion process, the clamping block on the surface of the clamping column slides into the square groove of the fixing ring to form a secondary clamping. When the clamping claw is damaged, the clamping column and the limit plate can be removed, which is convenient for replacement when the clamping claw is damaged. BRIEF DESCRIPTION OF THE DRAWINGS

After loosening the limit card plate 4, the spring 2 drives it to rebound to limit the extension plate 18. The connecting core rod 8 and the support column 1 are limited and fixed. When a new clamping claw needs to be installed, the first clamping block 6 and the second clamping block 11 are fitted on the surface of the connecting core rod 8, and then the limiting plate 9 is slid into the clamping groove 10 of the first clamping block 6 and the second clamping block 11 to form a preliminary clamping connection, and then the clamping column 19 is fixed by the fixing block 23 on the side of the limiting plate 9. The fixing ring 22 is inserted into the connecting groove 20. During the insertion process, the clamping block 24 on the surface of the clamping column 19 slides into the square groove 21 of the fixing ring 22 to form an enhanced clamping lock.
