Abstract
Description
Technical Field
[0001] This utility model relates to the field of centrifugal roll manufacturing technology, and in particular to an automatic centering device for tooling assembly. Background Technology
[0002] In the centrifugal roll manufacturing process, the assembly of cold-rolled molds and risers still largely relies on the traditional method of "crane hoisting + manual close-range assistance." The core process involves operators standing below or to the side within a 0.3–0.8 m danger zone, visually observing and directing the crane with hand gestures to manually align the riser (weighing 2–8 tons and reaching temperatures of 150–250 °C) with the cold-rolled stop, and then manually fine-tuning until a perfect fit is achieved. This operating mode has long suffered from the following prominent drawbacks: 1. Personnel entering high-risk fall zones During the hoisting process, the swing amplitude of the riser can reach ±100 mm, and the operator must remain directly below the hoisting trajectory. Once the lifting equipment fails or the riser slips, it is very easy to cause serious casualties such as crushing or squeezing.
[0003] 2. Risk of heat radiation and high-temperature burns The heat storage at the riser causes the surface radiation temperature to reach ≥150 ℃, and the ambient temperature in summer can reach above 45 ℃; operators are exposed for a long time, and heatstroke and burn incidents occur frequently.
[0004] 3. Low centering accuracy, repeated adjustments are time-consuming. The coaxiality error is generally ≥3 mm when manually inspected, requiring multiple lifting and lowering of the crane and correction with crowbars and hammers. The average time for a single set of equipment is 20–30 minutes. At the same time, repeated lifting increases the fatigue of the lifting slings and further amplifies the safety risks.
[0005] 4. Lack of universal positioning tooling Existing simple "V" shaped pads or locating pins can only provide coarse positioning and cannot simultaneously constrain radial and angular degrees of freedom; different specifications of risers require frequent replacement of accessories, and still cannot avoid close manual intervention.
[0006] Therefore, how to ensure the coaxiality (≤1 mm) of the cold mold and riser and the end face fit rate (≥90%), while expanding the safe distance of operators to more than 1.5 m through mechanized centering devices and achieving one-time precise assembly, has become an urgent technical problem to be solved in the field of centrifugal roll manufacturing. Utility Model Content
[0007] The technical problem to be solved by this utility model is to provide an automatic alignment device for tooling assembly, so as to achieve one-time precise assembly of the cold mold and riser coaxiality.
[0008] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: An automatic alignment device for tooling assembly includes an annular base, at least three outer supports arranged on the inner side of the outer edge of the base, at least three inner supports arranged on the inner side of the outer supports, a top plate arranged on the inner supports, and risers sleeved on the top plate; the top plate and the base are concentric circles; the risers are provided in a plurality of sizes, the inner diameter of the risers is the same as the outer diameter of the top plate, but the wall thickness is different.
[0009] A further improvement of the present invention is that the chassis is annular, and several sets of external mounting holes are symmetrically arranged on the edge of the chassis. Each set of external mounting holes includes several pairs of mounting holes arranged from the edge of the chassis toward the center of the circle, and several pairs of internal mounting holes are symmetrically arranged on the outer side of the inner circle.
[0010] A further improvement of the present invention is that the inner support includes several angle steels symmetrically arranged on the outer side of the inner circle, and the angle steels are welded to the top plate.
[0011] A further improvement of the present invention is that the outer support includes several T-shaped steels symmetrically arranged on the inner side of the outer edge of the chassis. The flanges of the T-shaped steels are parallel to the tangents of the corresponding outer edge of the chassis. The web of the T-shaped steels includes an inclined section and a vertical section arranged sequentially from top to bottom. The inclined section is inclined from the flange towards the outer center.
[0012] A further improvement of this utility model is that the angle between the outer edge of the inclined segment and the vertical line is in the range of 15° to 45°.
[0013] A further improvement of the present invention is that the inclined segment is configured as a whole.
[0014] A further improvement of the present invention is that the inclined segment is configured as a first inclined segment and a second inclined segment, wherein the angle between the edge of the first inclined segment and the vertical line is smaller than the angle between the edge of the second inclined segment and the vertical line.
[0015] A further improvement of this utility model is that the outer diameter of the top plate is in the range of 500-700mm.
[0016] A further improvement of this utility model is that the riser thickness ranges from 100mm to 400mm.
[0017] A further improvement of this utility model is that: the outer support is set to four, and the inner support is set to four.
[0018] The technological advancements achieved by this utility model due to the adoption of the above technical solution are as follows: 1. This utility model forms a two-stage mechanical alignment of "coarse guidance and fine positioning" by setting an outer support and an inner support, which can complete the cold mold assembly without close manual intervention. It is inherently safe, simple in structure and quick to change.
[0019] 2. This utility model achieves multi-size cold-type compatibility by setting replaceable risers. Attached Figure Description

[0023] like Figure 1 , 2 As shown, an automatic alignment device for tooling assembly includes an annular base 1, four outer supports 2 symmetrically arranged on the inner side of the outer edge of the base 1, four inner supports 3 symmetrically arranged on the inner side of the outer supports 2, a top plate 4 arranged on the inner supports 3, and a riser sleeved on the top plate 4; the top plate 4 and the base 1 are concentric circles; the inner diameter of the riser is the same as the outer diameter of the top plate 4. The chassis 1 is annular, and four sets of external mounting holes are symmetrically arranged on the edge of the chassis 1. Each set of mounting holes includes five pairs of mounting holes arranged from the edge of the chassis 1 toward the center of the circle, which are respectively 450mm, 500mm, 550mm, 600mm and 650mm away from the center of the circle, for mounting the outer bracket 2. Four pairs of mounting holes are symmetrically arranged on the outer side of the inner circle for mounting the inner bracket 3. The inner support 3 consists of four angle steels symmetrically arranged on the outer side of the inner circle, and the angle steels are welded to the top plate 4. The outer support 2 consists of four symmetrically arranged T-shaped steel sections on the inner side of the outer edge of the chassis 1. The flanges of the T-shaped steel sections are parallel to the tangents of the corresponding outer edge of the chassis 1. The web of the T-shaped steel section includes an inclined section and a vertical section arranged sequentially from top to bottom. The inclined section is inclined from the flange towards the outer center. Figure 3 As shown, the inclined segment can be configured as a single unit, such as... Figure 4 As shown, the inclined segment can also be configured as a first inclined segment and a second inclined segment; the angle between the outer edge of the inclined segment and the vertical line is in the range of 15° to 45°; The outer diameter of the top plate 4 ranges from 500 to 700 mm; The riser is configured as a plurality of risers, the inner diameter of which is the same as the outer diameter of the top plate 4, and the wall thickness ranges from 100mm to 400mm.
[0024] How to use: Commissioning phase: Select the appropriate riser based on the type of cooler to be installed. For example, the outer diameter of the existing top plate 4 is 500mm, and the inner diameter of the cold type to be installed is 700mm and the outer diameter is 1000mm. In this case, the inner diameter of the riser is selected to be 500mm and the thickness is 100mm, which matches the inner diameter of the cold type of 700mm.
[0025] Coarse positioning: The overhead crane lifts the cold mold and moves it directly above the top box. The operator (at this time in a safe area) directs the overhead crane to slowly descend via remote control or hand gestures.
[0026] Mechanical guidance: During the descent of the cold-formed section, the cold-formed section contacts the inclined section of the outer support 2, achieving a wide range of coarse guidance and limiting the horizontal swing of the cold-formed section.
[0027] Precise positioning: As the cold-form continues to descend, it enters the vertical section of the outer support 2, achieving final precise alignment. At this point, the cold-form stop and riser are completely coaxial.
[0028] The grate assembly is complete: The overhead crane continues to descend slowly, and the cold-formed stop smoothly and without impact falls into the riser, completing the grate assembly. Throughout the entire process, the operator remains at least 5 meters away.
[0029] In summary, this invention enables precise one-time assembly of the cold mold and riser to achieve coaxiality.
