It includes a positioning base, inside which is installed an irregularly shaped adapter component extending to the outside for adapting to the shape of an irregularly shaped roll. The adapter component includes a clamping part connected inside the positioning base and a driving part installed inside the positioning base and connected to the clamping part. In this utility model, when the irregularly shaped roll is compressed, it can compress the uprights downwards and compress the spring strip.

Thus, the first and second clamping plates can be used to clamp all the uprights alternately, allowing the uprights to adapt to and position different irregularly shaped rolls.

Description

Technical Field

[0001] This utility model belongs to the field of roll welding technology, specifically relating to an irregularly shaped positioning device for roll welding. Background Technology

[0002] Roll welding is a manufacturing process in which metal sheets are rolled and formed, and then welded together to form a cylindrical structure. During the welding process, positioning devices are required to prevent the rolls from shifting. Irregularly shaped rolls are different from normal round or rectangular rolls, and special irregularly shaped positioning devices are required for fixing them.

[0003] Existing irregularly shaped drum positioning devices mainly rely on a single clamping force to achieve drum positioning in practical applications. However, this method of positioning based solely on clamping force has obvious drawbacks. Due to the lack of other effective auxiliary positioning methods, the clamping is often not tight when dealing with irregularly shaped drums with different characteristics, which leads to the drum being prone to displacement during use, affecting normal production and product quality. Utility Model Content

[0004] The purpose of this utility model is to provide an irregularly shaped positioning device for welding rolls, which aims to solve the obvious drawbacks of the existing technology that relies solely on clamping force for positioning. Due to the lack of other effective auxiliary positioning methods, when dealing with irregularly shaped rolls with different characteristics, the clamping is often not tight, which leads to the rolls easily shifting during use, affecting the normal production process and product quality.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a non-circular positioning device for roll welding, comprising a non-circular adaptation component extending to the outside and adapted to the shape of a non-circular roll, the non-circular adaptation component comprising a clamping part connected inside the positioning base, a driving part installed inside the positioning base and connected to the clamping part, and an adaptation part connected between the clamping part and the positioning base, wherein a positioning component for fixing the non-circular roll is installed on the upper surface of the positioning base.

[0006] As a preferred embodiment of the irregular positioning device for roll welding of this utility model, the clamping part includes a first clamping plate disposed inside the positioning base cavity, a first guide groove disposed on the inner side wall of the positioning base and adapted to the first clamping plate, a first rubber ring connected to the inner wall of the through hole of the first clamping plate, a second clamping plate disposed inside the positioning base cavity, a second guide groove disposed on the inner side wall of the positioning base and adapted to the second clamping plate, and a second rubber ring connected to the inner wall of the through hole of the first clamping plate and corresponding to the first rubber ring.

[0007] As a preferred embodiment of the irregular positioning device for roll welding of this utility model, the driving part includes a first connecting block connected to the upper surface of the first clamping plate, a first spiral tube that penetrates and is connected inside the first connecting block, a second connecting block that penetrates the first clamping plate and is connected to the surface of the second clamping plate, a second spiral tube that penetrates and is connected inside the second connecting block, and a bidirectional lead screw that penetrates the interior of the first spiral tube and the second spiral tube and is threaded together.

[0008] As a preferred embodiment of the irregular positioning device for drum welding of this utility model, the driving unit further includes a bearing sleeved on the surface of the bidirectional lead screw and fitted onto the side surface of the positioning base, a driven bevel gear connected to the end of the bidirectional lead screw, a drive motor installed on the inner side wall of the positioning base, and an active bevel gear connected to the output end of the drive motor and meshing with the driven bevel gear.

[0009] As a preferred embodiment of the irregular positioning device for roll welding of this utility model, the adapter includes a horizontal plate connected to the inner wall of the positioning base, a vertical rod penetrating the positioning base, the first rubber ring, the second rubber ring and the interior of the horizontal plate, a limiting plate connected to the surface of the vertical rod and located below the second clamping plate, and a spring strip connected to the lower surface of the limiting plate and connected to the horizontal plate.

[0010] As a preferred embodiment of the irregular positioning device for roll welding of this utility model, the positioning component includes a support arm connected to the upper surface of the positioning base, a telescopic rod installed on the horizontal part of the support arm, a pressure plate connected to the output end of the telescopic rod, and a rubber pad connected to the lower surface of the pressure plate.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] In this invention, when the irregularly shaped drum is compressed, it can compress the uprights downwards and compress the spring strip. Then, when the drive motor runs, it drives the active bevel gear to rotate. When the active bevel gear rotates, it drives the bidirectional lead screw to rotate through the driven bevel gear, which in turn drives the first and second solenoids to move in opposite directions. When the first and second solenoids move in opposite directions, they respectively drive the first and second clamping plates to move in opposite directions through the first and second connecting blocks. Thus, all the uprights can be clamped by the first and second clamping plates in an alternating manner. In this way, the uprights can be adapted to the shape of different irregularly shaped drums and positioned accordingly. Attached Figure Description

[0024] In practical use, when the first clamping plate 2011 is subjected to force, it can slide on the inner wall of the first guide groove 2012, thereby restricting the movement direction of the first clamping plate 2011; and when the second clamping plate 2014 is subjected to force, it can slide on the inner wall of the second guide groove 2015, thereby restricting the movement direction of the second clamping plate 2014.

[0025] Preferably, the drive unit 202 includes a first connecting block 2021 connected to the upper surface of the first clamping plate 2011, a first threaded tube 2022 penetrating and connected inside the first connecting block 2021, a second connecting block 2023 penetrating the first clamping plate 2011 and connected to the surface of the second clamping plate 2014, a second threaded tube 2024 penetrating and connected inside the second connecting block 2023, and a bidirectional lead screw 2025 penetrating the first threaded tube 2022 and the second threaded tube 2024 and threadedly connected.

[0026] In practical use, when the bidirectional lead screw 2025 rotates, it can drive the first solenoid 2022 and the second solenoid 2024 to move in opposite directions. When the first solenoid 2022 and the second solenoid 2024 move in opposite directions, they respectively drive the first clamping plate 2011 and the second clamping plate 2014 to move in opposite directions through the first connecting block 2021 and the second connecting block 2023, so that the first clamping plate 2011 and the second clamping plate 2014 can be staggered.

[0031] In practical use, when the telescopic rod 302 extends, it can drive the pressure plate 303 to move downward. When the pressure plate 303 drives the rubber pad 304 to move downward to the surface of the drum, the drum can be positioned.

[0032] Working principle: When using this positioning device, first place the irregularly shaped drum on the top of the upright 2032 group, then run the telescopic rod 302. When the telescopic rod 302 extends, it can drive the rubber pad 304 to move downward through the pressure plate 303. When the pressure plate 303 drives the rubber pad 304 to the surface of the irregularly shaped drum, it can squeeze it. When the irregularly shaped drum is squeezed, it can squeeze the upright 2032. When the upright 2032 is squeezed, it can move downward and compress the spring strip 2034.

[0033] Then the drive motor 2028 can be operated. When the drive motor 2028 is running, it can drive the active bevel gear 2029 to rotate. When the active bevel gear 2029 rotates, it drives the bidirectional lead screw 2025 to rotate through the driven bevel gear 2027.
