Description

Technical Field

[0001] This utility model relates to a fine-tuning fixture for the processing of clamping rollers, belonging to the field of machining positioning and adjustment. Background Technology

[0002] In hot rolling production lines, the pinch rolls of the coiler are an important component. The roll shape and grinding precision of the pinch rolls are crucial for controlling the coil shape and coiling accuracy of hot-rolled steel coils. Errors in the roll shape of the pinch rolls can easily cause vibrations during coiler operation, resulting in product quality defects such as roll marks and loose coils on the strip surface.

[0003] The specific problems currently existing in the processing of pinch rolls are as follows: (1) Currently, the pinch roller is supported by a fixed pad for positioning. It is difficult for the central axis of the pinch roller to coincide with the central axis of the machine tool. After processing, the roller shape becomes eccentric. Defects such as pressure oscillation and roller marks after being put on the machine are one of the important reasons why the processing accuracy of the pinch roller does not meet the requirements. (2) The original pinch roller is a fixed support method and cannot be adjusted. It is difficult to align the pinch roller on the machine tool. It needs to be repeatedly aligned and ground to meet the usage requirements. This results in high labor intensity for operators, low grinding efficiency, and increased grinding amount of the pinch roller, leading to increased costs. Utility Model Content

[0004] The technical problem to be solved by this utility model is that the existing pinch rollers are fixed and cannot be adjusted, making it difficult to align the pinch rollers on the machine tool and resulting in low grinding efficiency.

[0005] The technical solution adopted by this utility model to solve its technical problem is: a fine-tuning fixture for processing pinch rollers, including a base, a wedge, an adjustment component and a mounting base. The mounting base has a U-shaped structure and is set at the upper end of the base. The wedge passes through the bottom of the mounting base and can move up and down through the adjustment component.

[0006] The aforementioned device includes a wedge-shaped trapezoidal structure.

[0007] Furthermore, the adjustment component in the above device includes a slider and a lead screw. The upper end of the base is provided with an installation groove, and the lead screw is rotatably disposed in the installation groove. The slider passes through the lead screw and is threadedly connected to the lead screw. The lower end of the slider is placed in the installation groove, and the upper end of the slider is an inclined surface that contacts and connects with the lower end surface of the wedge.

[0008] Furthermore, the slider in the above-mentioned device includes a left slider and a right slider arranged symmetrically, the threads at both ends of the lead screw have opposite directions, and the left slider and the right slider are respectively inserted through both ends of the lead screw and threadedly connected to the lead screw.

[0009] Furthermore, in the above-mentioned device, the left and right sliders are both right-angled trapezoids, and the right-angled sides of the left and right sliders are set on the bottom surface of the mounting groove. The left and right sliders are provided with mounting holes inside, and the two ends of the mounting holes are set on the upper and lower bottoms of the trapezoidal left and right sliders. Threaded sleeves are fixed in the mounting holes respectively, and the lead screw is threadedly connected to the threaded sleeves.

[0010] In the aforementioned device, adjusting screws are provided on both sides of the opening of the mounting base, and the adjusting screws are threadedly connected to the side wall of the opening of the mounting base.

[0011] In the aforementioned device, the mounting base has countersunk holes spaced at its bottom end, and the base has threaded holes at its upper end. The mounting base and the base are detachably connected by screws.

[0012] The device also includes baffles spaced apart, with a lead screw passing through the baffles and the baffles being detachably connected to the mounting grooves of the base via screws; one end of the lead screw extends out of the baffle and is provided with a square adjusting head.

[0013] Furthermore, the base of the aforementioned device has L-shaped openings at both ends, and threaded holes are provided on the opening side. Through holes are provided at intervals on the baffle, and the screw passes through the baffle and is threadedly connected to the base.

[0014] Furthermore, the lead screw in the above device is provided with a shoulder on the outer wall, and the shoulder is located inside the baffle. The baffle is fitted with retaining rings on both sides, so that the lead screw can rotate and be mounted on the baffle.

[0015] The beneficial effects of this utility model are: by replacing the mounting base, this structure can adapt to the processing of various box-type rolls, and has strong practicality. This structure actually uses a U-shaped mounting base to achieve positioning at both ends of the pinch roll during grinding, an adjusting component to achieve vertical adjustment of the pinch roll, and an additional pad on the inner wall of the mounting base to achieve initial positioning of the pinch roll. This structural design allows for centering adjustment of the pinch roll in four directions (up, down, left, and right). Actual field use has shown that the equipment is safe and easy to operate, while also improving on-site work efficiency. Attached Figure Description

The mounting base 3 has a U-shaped structure and is located on the upper end of the base 4. The wedge 11 passes through the bottom of the mounting base 3 and can move up and down via the adjustment component. Those skilled in the art will understand that this structure is simple, reliable, and easy to operate. Using this fixture for processing the pinch roll 1 results in a simple alignment process, low workload, and high grinding efficiency. In practice, the connecting seats 2 at both ends of the pinch roll 1 are placed inside the openings of the mounting base 3, and initial positioning is achieved on both sides via pads 32. Simultaneously, since the wedge 11 passes through the bottom of the mounting base 3 and can move up and down via the adjustment component, and since the lower end of the connecting seat 2 is in contact with the upper end of the wedge 11, the adjustment component is used to adjust the wedge 11 to achieve the purpose of adjusting the vertical position of the connecting seat 2. The base 4 is positioned at the lower end of the mounting base 3 for easy connection with the connecting plate 8. In practice, the structural strength of the connection between the base 4 and the connecting plate 8 can be ensured by the stiffening rib 7. The connecting plate 8 is connected to the base plate 9 by bolts, and the base plate 9 is slidably connected to the guide rail 10.

Those skilled in the art will understand that the preferred structure of the adjusting component preferably includes a slider and a lead screw 5. The upper end of the slider contacts the lower end of the wedge block 11. Since the wedge block 11 has an inverted trapezoidal structure, the upper end of the slider should be in contact with the inclined surface structure.

A slider is threaded onto the lead screw 5 and connected to it, with its lower end positioned within the groove. The groove's limiting mechanism ensures the slider can only move axially along the lead screw 5. This structural design, by rotating the lead screw 5 to move the slider up and down, achieves the adjustment of the pinch roller 1, effectively reducing labor intensity and improving work efficiency.
