Description

Technical Field

[0001] This utility model relates to the field of docking fixtures, and in particular to a docking fixture for free rolls of a continuous casting machine. Background Technology

[0002] The free roll of the continuous casting machine is composed of two segmented rolls, with two bearing seats in the middle. A core sleeve with four O-rings is installed in the core of the two rolls to form a cooling water chamber to cool the rolls. Two through covers are installed between the middle bearing seats. The two through covers have two seals. After assembly, the two bearing seats form a lubricating grease chamber and can prevent external cooling water and oxide slag from entering the bearing seats.

[0003] In existing continuous casting machines that use two segmented rolls for free roll assembly, the operator first axially positions the two segmented rolls, and then uses external equipment to assemble them. During this process, the operator needs to spend a long time axially positioning the two segmented rolls, which results in a long assembly time and low assembly efficiency for the free rolls of the continuous casting machine.

[0013] The above-mentioned and other technical features and advantages of this utility model will be described in more detail below with reference to the accompanying drawings.

[0014] Combined with appendix Figure 1-3 As shown, a free roll docking fixture for a continuous casting machine is disclosed. The free rolls include two segmented rolls 1, each of which includes a roll body 1b and two bearing seats 1a. The docking fixture includes a worktable 2; two slide rails 3, which are arranged parallel to each other on the worktable 2; an intermediate baffle 4, which is detachably disposed in the middle of the upper end face of the worktable 2; and two docking units, which are respectively disposed on the left and right sides of the intermediate baffle 4 for pressing and docking the two segmented rolls 1. Each docking unit includes an outer baffle 5 disposed at the end of the worktable 2, a hydraulic top 6 disposed on the outer baffle 5, a V-block 7 slidably mounted on the slide rail 3 for placing the roll body 1b, and two bearing seat placement platforms 8 located at both ends of the V-block 7, slidably mounted on the slide rail 3 for placing the bearing seats 1a. The bearing seat placement platforms 8 are provided with a centering clamping mechanism for centering and clamping the bearing seats 1a.

[0015] It should be noted that the length of the V-block 7 is less than the length of the roller body 1b, and the length of the bearing seat placement platform 8 is less than the length of the bearing seat 1a.

[0016] Each of the aforementioned centering and clamping mechanisms includes a mounting groove 9, which is disposed on the bearing housing placement platform 8; a lead screw 10, which is rotatably mounted in the mounting groove 9, with the front and rear threads having opposite directions; a handwheel 11, which is disposed on the outer end of the lead screw 10; and two grippers 12, which are symmetrically and slidably mounted in the mounting groove 9 and respectively threaded into the front and rear halves of the lead screw 10. This design is simple in structure, provides stable clamping, and is convenient to operate. When clamping the bearing housing 1a, rotating the handwheel 11 drives the lead screw 10 to rotate. As the lead screw 10 rotates, the grippers 12 gradually move inward along the mounting groove 9, thereby clamping the bearing housing 1a.

[0017] The workbench 2 has a insertion slot 4a in the middle, and the intermediate baffle 4 is detachably inserted into the insertion slot 4a. This design is simple and easy to assemble and disassemble.

[0018] When assembling a single segmented roller 1,

[0019] First, insert the intermediate baffle 4 into the insertion slot 4a;

[0020] Then, the roller body 1b is hoisted onto the V-block 7 using hoisting equipment, the bearing seat 1a is placed on the bearing seat placement platform 8, and the centering and clamping mechanism is used to connect and clamp the roller body 1b onto the V-block 7.

[0021] Finally, the hydraulic jack 6 is activated. As the hydraulic jack 6 extends, the bearing housing 1a and the roller body 1b gradually move closer to each other, completing the assembly of the segmented roller 1.

[0022] When assembling the free roller, i.e., connecting two segmented rollers 1, after completing the assembly of a single segmented roller 1, remove the intermediate baffle 4; then place the core sleeve at the end of any roller body 1b at the connection point of the segmented roller 1; finally, start the hydraulic jack 6 to continue pressing, and complete the connection of the segmented rollers 1.

[0023] This utility model is not limited to the above embodiments. Based on the technical solutions disclosed in this utility model, those skilled in the art can make some substitutions and modifications to some of the technical features without creative labor, and these substitutions and modifications are all within the protection scope of this utility model.
