Description

Technical Field

[0001] This utility model belongs to the field of closed-hole flat roller adjustment technology, specifically a closed-hole flat roller lateral positioning adjustment mechanism. Background Technology

[0002] Flat rolls typically refer to rolls with a flat or curved surface. Closed-gauge rolls are a type of rolling pass characterized by the roll gap, i.e., the roll profile is located in the closed portion of the roll, meaning the roll profile is completely surrounded by the roll body. This design is mainly used for rolling products such as wide flat steel, enabling high-precision rolling of the material's sides. During the processing and assembly of closed-gauge flat roll systems, axial cumulative errors are inevitable due to manufacturing tolerances and installation fit factors. To ensure rolling accuracy, a lateral adjustment mechanism is needed to align the centerline after installation to eliminate static errors and restore the roll system to the designed axial zero position, ensuring the stability and reliability of the rolling process. In existing horizontal adjustment mechanisms for flat rollers, the connection between the flat roller and the adjustment mechanism is prone to loosening or slight displacement during continuous rotation and high-load operation. This affects the linkage accuracy between the adjustment mechanism and the flat roller, thus impacting operational stability. Therefore, a closed-hole flat roller lateral positioning adjustment mechanism is proposed to address the above problems. Utility Model Content

It is equipped with a lateral adjustment and positioning structure. By moving the base on the outer wall of the lateral precision adjustment screw, the positioning component at the bottom and the base structure and all components above it, including the column, support seat, flat roller assembly, etc., move laterally along the screw axis.

[0013] 2. This utility model provides a lateral positioning and adjustment mechanism for a closed-hole flat roller. A positioning bushing is provided. By providing a positioning bushing on the outer wall of the base, after the lateral adjustment is performed, the positioning bushing limits the external position of the base, effectively eliminating the assembly gap between the lateral precision adjustment screw and the base.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Specific implementation examples are given below.

[0018] Please see Figures 1-5 This utility model provides a lateral positioning and adjustment mechanism for a closed-hole flat roller, including a base structure 1, which includes a base 101. The top of the base 101 has a positioning insertion hole 102. A lateral adjustment structure 2 is inserted into the side wall of the base 101. The lateral adjustment structure 2 includes a lateral precision adjustment screw 201. A positioning bushing 202 is movably sleeved on the outer wall of the lateral precision adjustment screw 201. A positioning mechanism 3 is provided on the top of the base 101. The positioning mechanism 3 includes a support 301. Mounting plates 302 are connected to both sides of the outer wall of the support 301. A fixing structure 4 is inserted into the top of the support 301.

[0019] Furthermore, such as Figure 1 , Figure 2 and Figure 3As shown, the transverse precision adjusting screws 201 in the transverse adjustment structure 2 are provided in two sets horizontally distributed. The transverse precision adjusting screws 201 are movably sleeved on the inner wall of the circular hole opened on the outer wall of the base 101, and the positioning bushing 202 is adapted to the outer wall of the transverse precision adjusting screw 201. During operation, rotating the two horizontally arranged transverse precision adjusting screws 201 will cause axial movement of the screws themselves, since the screws are movably sleeved with the circular hole on the side wall of the base 101. The T-shaped positioning bushing 202 is sleeved on the transverse precision adjusting screw 201, and its outer end face is in close contact with the outer side of the base 101. Therefore, when the transverse precision adjusting screw 201 is moved axially, it will push or pull the positioning bushing 202, thereby transmitting the precise linear displacement to the base 101 connected to the inner side of the positioning bushing 202, thus realizing the transverse positioning adjustment of the entire upper structure.

[0020] Furthermore, such as Figure 2 , Figure 3 and Figure 4 As shown, the positioning bushing 202 has a T-shaped sleeve structure, and its outer end face is fitted and connected to the outer surface of the base 101. During operation, after lateral adjustment, the positioning bushing 202 limits the external position of the base 101, further strengthening the fixing effect.

[0021] Furthermore, such as Figure 3 and Figure 4 As shown, the base structure 1 also includes a column 103, which is fixedly installed on both sides of the top of the base 101. A circular groove is formed on the top of the column 103. During operation, the column 103 on the base provides support and mounting points for the positioning mechanism 3. The bottom of the mounting plate 302 of the positioning mechanism 3 is movably connected to the top of the column 103 through a fixing structure 4.

[0022] Furthermore, such as Figure 4 As shown, the top two sides of the column 103 are movably connected to the bottom of the mounting plate 302. A support base 301 is connected to the inner wall of the mounting plate 302, and a positioning structure is movably installed on the inner wall of the support base 301. During operation, the column 103 is connected to the positioning mechanism 3 through the fixing structure 4. The support base 301 has a positioning structure inside, which fixes the position of the base 101.

[0023] Furthermore, such as Figure 1 , Figure 3 and Figure 5As shown, the positioning structure includes a connecting rod 303, with a matching steering wheel 304 fixedly mounted at the top of the connecting rod 303 and a positioning component 305 fixedly mounted at the bottom of the connecting rod 303. During operation, the steering wheel 304 rotates, causing the connecting rod 303 to rotate and rise. The connecting rod 303 then moves the positioning component 305 at the bottom. The positioning component 305 is designed as a combination of an arc-shaped plate and a positioning plate. During operation, the positioning component 305 moves downwards, and its rectangular positioning plate inserts into the positioning hole 102 of the base, thereby fixing the base 101.

[0024] Furthermore, such as Figure 5 As shown, the positioning component 305 includes an arc-shaped plate and a positioning plate. Rectangular positioning plates are fixedly connected to both sides of the bottom of the arc-shaped plate, and the positioning plates are movably inserted into the inner wall of the positioning socket 102. During operation, the insertion connection between the positioning plate and the positioning socket 102 is fixed, realizing the precise positioning of the base 101 in the horizontal plane and eliminating the lateral swing degree of freedom.

[0025] Furthermore, such as Figure 4 As shown, the fixing structure 4 includes a pin 401, which is adapted to be inserted into the inner wall of the circular groove. A fixing member 402 is fixedly sleeved on the outer wall of the pin 401, and an end cap 403 is fixedly connected to the top of the pin 401. During operation, the pin 401 is inserted into the circular groove at the top of the column 103, and the fixing member 402 moves down with the pin 401 to fix it, thereby fixing the positioning mechanism 3 to the base structure 1.

[0026] Working principle: The positioning mechanism 3 is installed on the column 103 via its mounting plate 302 and the fixing structure 4. During adjustment, the two transverse precision adjusting screws 201 are rotated. The transverse precision adjusting screws 201 rotate in the round holes on the side wall of the base 101 and generate axial movement. The outer end face of the T-shaped positioning bushing 202 is in close contact with the base 101, which limits the outer side of the base 101 and eliminates the assembly gap between the transverse precision adjusting screws 201 and the base 101. After adjustment and locking, the long-term stability of the positioning is ensured, which drives the positioning mechanism 3 of the entire upper part of the base structure 1 to move in the horizontal direction. After the transverse adjustment is in place, the positioning structure inside the positioning mechanism 3 is operated to push or rotate the positioning part 305 at the bottom to move downward. The rectangular positioning plate at the bottom of the positioning part 305 is vertically inserted into the positioning insertion hole 102 pre-opened at the top of the base 101, thereby fixing the position of the base 101 and enhancing the stability after adjustment.

[0027] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
