Description

Technical Field

[0001] This utility model relates to the field of casting mold manufacturing technology, and in particular to a welding and positioning device for accessories on a casting mold. Background Technology

[0002] In the manufacturing process of sand molds, conical cylindrical components need to be welded onto the male mold for positioning or shaping. In existing technology, taking a welding positioning bracket disclosed in patent document CN108971872B as an example, when welding cylindrical components, a horizontal and vertical dimension positioning method is often used, followed by clamping to achieve positioning. However, this method has significant drawbacks: because the cylindrical components need to be welded, a positioning device is required to provide a pre-pressure to the cylindrical component during positioning, ensuring it adheres tightly to the steel plate. However, existing positioning devices only achieve positioning on a flat surface and cannot provide pre-pressure to the conical cylindrical component, leading to unstable bonding between the cylindrical component and the steel plate after welding. Furthermore, during welding, the lower edge of the cylindrical component needs to be welded as a whole, typically using fish-scale welding. However, existing positioning devices interfere with the welding core rod, preventing continuous welding and affecting welding efficiency.

[0003] To solve the above problems, a welding positioning device for accessories on a casting mold is provided. Utility Model Content

[0004] In order to overcome the defects of the prior art, this utility model provides a welding positioning device for accessories on casting molds, which effectively solves the problem that the positioning of conical components on male molds lacks pre-pressure during welding, and cannot be continuously and uninterruptedly welded around a circle.

[0005] The technical solution includes a ring-shaped base with multiple magnets fixed at the lower end of the base. A rotatable outer ring is fitted on the base, and a pressing mechanism is located above the outer ring. The pressing mechanism consists of multiple concentric cylinders. The outermost cylinder is fixed to the outer ring by multiple fixing rods. Multiple elastic elements are connected between adjacent cylinders, allowing them to move up and down.

[0006] To better install the elastic element, multiple grooves are provided on the side wall of the cylinder, so that adjacent cylinders can only move up and down but cannot rotate.

[0007] The elastic element is a compression spring.

[0008] A tapered roller bearing is installed between the outer ring and the base.

[0009] This utility model has a clever structure that enables rapid positioning by pre-pressing the conical component onto the steel plate; at the same time, it ensures that the welding core rod is not interfered with during the welding process, and allows for uninterrupted continuous welding of one circle.

[0014] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings.

[0015] Depend on Figures 1 to 4 As shown, this utility model includes an annular base 1, with multiple magnets 2 fixed at the lower end of the base 1, and a rotatable outer ring 3 fitted on the base 1. A pressing mechanism is located above the outer ring 3. The pressing mechanism consists of multiple concentric cylinders 4, with the outermost cylinder 4 fixed to the outer ring 3 by multiple fixing rods 5. Multiple elastic elements 6 are connected between adjacent cylinders 4, allowing adjacent cylinders 4 to move up and down.

[0016] To better install the elastic element 6, multiple grooves 7 are provided on the side wall of the cylinder 4, so that adjacent cylinders 4 can only move up and down but cannot rotate.

[0017] The elastic element 6 is a compression spring.

[0018] A tapered roller bearing is installed between the outer ring 3 and the base 1.

[0019] It is more convenient to use an electromagnet 2 as the magnet 2 mentioned above.

[0020] It is worth noting that the elastic element 6 can be replaced by an elastic rope in addition to a compression spring.

[0021] In use, place the conical component in a suitable position on the steel plate, and then place the device on the steel plate from top to bottom. At this time, the upper end of the conical component is inserted into the clamping mechanism. Then, press the base 1 down and press it tightly against the steel plate. The magnet is attracted to the steel plate. At this time, multiple cylinders 4 are displaced vertically. Under the action of the elastic element 6, multiple cylinders 4 provide downward pre-pressure to the conical component, so that the lower end of the conical component is in close contact with the steel plate. At this time, welding can be carried out. During the welding process, fish scale welding is generally used. During the welding process of the welding core rod along the outer edge of the lower end of the conical component, since the bearing is installed between the outer ring 3 and the base 1, the welding core can continue to weld around the outer edge of the lower end of the conical cylinder without interference, and the welding is completed in one go.

[0022] It is worth noting that since the outer ring 3 also drives the clamping mechanism to rotate when it rotates, but the conical part is required to remain stationary during welding, under the premise of sufficient preload, the friction between the lower edge of the cylinder 4 and the conical part is less than the friction between the conical part and the steel plate, thus ensuring that the conical part does not rotate. Of course, ball bearings can also be installed on the lower edge of the cylinder, which can greatly reduce the friction between the cylinder 4 and the conical part, further ensuring that the conical part does not rotate.

[0023] This utility model has a clever structure that enables rapid positioning by pre-pressing the conical component onto the steel plate; at the same time, it ensures that the welding core rod is not interfered with during the welding process, and allows for uninterrupted continuous welding of one circle.
