Technical Field

[0001] This utility model relates to the field of metal casting processing technology, and in particular to a positioning device for metal casting processing. Background Technology

[0002] Precise positioning is crucial for ensuring machining quality and efficiency in metal casting processing. Existing positioning devices for metal castings often suffer from insufficient positioning accuracy and inconvenient adjustment. Some devices are ill-suited for metal castings of different shapes and sizes, leading to casting displacement during machining and affecting machining accuracy. Other positioning devices are complex in structure and cumbersome to operate, reducing machining efficiency and increasing production costs. Therefore, there is an urgent need to design a flexible and precise positioning device for metal casting machining to meet actual production requirements. Utility Model Content

[0003] (1) Technical problems to be solved In order to solve the problems of insufficient positioning accuracy and inconvenient adjustment of existing positioning devices, and to achieve precise positioning of metal castings of different shapes and sizes, thereby improving processing quality and efficiency.

[0004] (2) Technical solution The technical solution of this utility model is as follows: a positioning device for metal casting processing, including a base, a working platform, a metal casting body, support columns, positioning components, and an adjustment component. The base has a rectangular structure and is set below the positioning device to support it. The working platform is fixedly installed on the upper surface of the base, and the metal casting body is set above the working platform. Multiple support columns are arranged in parallel inside the working platform, with one end of each support column abutting against the metal casting body. The abutting end of the support column against the metal casting body adopts an arc-shaped rubber structure. Multiple positioning components are symmetrically arranged on the side of the base, and the adjustment component is set between the positioning components and the base. Through the cooperation of components such as telescopic cylinders and rotating shafts in the positioning components, the metal casting can be positioned at multiple angles and directions. The anti-slip pads on the surface of the positioning columns further improve the stability of the positioning, ensuring that the metal casting will not shift during processing, effectively improving the processing accuracy. In conjunction with the adjustment component, the drive motor drives the lead screw to rotate, which can realize the movement of the moving block in the guide groove, thereby adjusting the position of the positioning component. This enables rapid and accurate positioning of castings in different positions, greatly improving the positioning efficiency.

[0005] Furthermore, the positioning assembly includes a movable plate, a telescopic cylinder, a movable plate, a rotating shaft, a positioning plate, and positioning posts. Four movable plates are respectively mounted on the side surface of the base. The telescopic cylinder is movably connected to the movable plate via a hinge. The movable plate is connected to the extended end of the telescopic cylinder via a hinge. The rotating shaft is mounted on the surface of the movable plate. The end of the movable plate away from the telescopic cylinder is connected to one end of the rotating shaft. The positioning plate is mounted on the rotating shaft end away from the movable plate. Two positioning posts are rotatably mounted on the surface of the positioning plate via bearings. Through the cooperation of components such as the telescopic cylinder and the rotating shaft in the positioning assembly, the metal casting can be positioned at multiple angles and directions. The anti-slip pads on the surface of the positioning posts further improve the stability of the positioning, ensuring that the metal casting will not shift during processing, effectively improving processing accuracy.

[0006] Furthermore, the outer surface of the positioning post is fitted with an anti-slip pad made of rubber, and the surface of the anti-slip pad is provided with multiple rubber protrusions, which can increase the friction between the anti-slip pad and the metal casting, prevent the casting from sliding during processing, and improve the stability during processing.

[0007] Furthermore, the adjustment component includes a moving block, a guide groove, a lead screw, and a drive motor. The moving block is welded to the side surface of the moving plate near the base. The side surface of the base has a convex-shaped guide groove. The moving block is adapted to the guide groove. The lead screw is set in the guide groove on the surface of the base. One end of the lead screw is rotatably connected to the base, and the other end of the lead screw is connected to the output shaft of the drive motor installed on the outside of the base. By driving the lead screw to rotate through the drive motor, the moving block can be moved in the guide groove, thereby adjusting the position of the positioning component. This enables rapid and accurate positioning of castings at different positions, greatly improving positioning efficiency.

[0008] Furthermore, casters are installed at the four corners of the base, and each caster is equipped with a brake device to facilitate the movement and fixation of the device, improve the flexibility of the device, and enable it to be quickly fixed in a designated position.

[0009] Furthermore, four hydraulic telescopic cylinders are installed at the bottom of the base. The four hydraulic telescopic cylinders are arranged in a rectangular shape, and a rectangular support plate is installed at the extended end of the hydraulic telescopic cylinder. The bottom surface of the support plate is provided with a rubber anti-slip pad. By setting up the hydraulic telescopic cylinders and the support plate, the height of the device can be adjusted according to actual needs. The rubber anti-slip pad on the bottom surface of the support plate can enhance the stability of the device.

[0010] Furthermore, a control box is also provided on the base, which contains a controller. The controller is electrically connected to the hydraulic telescopic cylinder, the telescopic air cylinder, and the drive motor. The electrical connection between the controller and each component realizes the automated control of the positioning device, simplifies the operation process, improves processing efficiency, and reduces labor costs.

Detailed Implementation

[0017] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0018] Example 1: Please see Figure 1-6 This utility model provides an embodiment: a positioning device for metal casting processing, including a base 1, a working platform 11, a metal casting body 12, support columns 13, positioning components 2, and adjustment components 3. The base 1 is rectangular and positioned below the positioning device to support it. The working platform 11 is fixedly installed on the upper surface of the base 1. The metal casting body 12 is positioned above the working platform 11. Multiple support columns 13 are arranged parallel to each other inside the working platform 11. One end of each support column 13 abuts against the metal casting body 12. The abutting end of the support column 13 against the metal casting body 12 is provided with an arc-shaped rubber structure. Multiple positioning components 2 are symmetrical. The adjustment component 3 is positioned on the side of the base 1 and between the positioning component 2 and the base 1. Through the cooperation of components such as the telescopic cylinder 22 and the rotating shaft 24 in the positioning component 2, the metal casting can be positioned at multiple angles and directions. The anti-slip pad on the surface of the positioning column 26 further improves the stability of the positioning, ensuring that the metal casting will not be displaced during processing, effectively improving the processing accuracy. In conjunction with the adjustment component 3, the lead screw 33 is driven to rotate by the drive motor 34, which can realize the movement of the moving block 31 in the guide groove 32, thereby adjusting the position of the positioning component 2. This enables rapid and accurate positioning of castings in different positions, greatly improving the positioning efficiency.

[0019] The positioning assembly 2 includes a movable plate 21, a telescopic cylinder 22, a movable plate 23, a rotating shaft 24, a positioning plate 25, and positioning posts 26. The four movable plates 21 are respectively set on the side surface of the base 1. The telescopic cylinder 22 is movably connected to the movable plate 21 through a hinge. The movable plate 23 is connected to the extended end of the telescopic cylinder 22 through a hinge. The rotating shaft 24 is installed on the surface of the movable plate 21. The end surface of the movable plate 23 away from the telescopic cylinder 22 is connected to one end of the rotating shaft of the rotating shaft 24. The positioning plate 25 is installed on the rotating shaft end of the rotating shaft 24 away from the movable plate 23. Two positioning posts 26 are rotatably mounted on the surface of the positioning plate 25 through bearings. Through the cooperation of components such as the telescopic cylinder 22 and the rotating shaft 24 in the positioning assembly 2, the metal casting can be positioned at multiple angles and directions. The anti-slip pads on the surface of the positioning posts 26 further improve the stability of the positioning, ensuring that the metal casting will not be displaced during processing, and effectively improving the processing accuracy.

[0020] The outer surface of the positioning post 26 is fitted with an anti-slip pad 27, which is made of rubber and has multiple rubber protrusions on its surface. This increases the friction between the anti-slip pad and the metal casting, prevents the casting from sliding during processing, and improves the stability during processing.

[0021] The base 1 is equipped with casters 4 at the four corners of the bottom, and each caster 4 is equipped with a brake device to facilitate the movement and fixation of the device, improve the flexibility of the device, and enable it to be quickly fixed in a designated position.

[0022] Four hydraulic telescopic cylinders 5 are installed at the bottom of the base 1. The four hydraulic telescopic cylinders 5 are arranged in a rectangular shape. A rectangular support plate 6 is installed at the extended end of the hydraulic telescopic cylinder 5. The bottom surface of the support plate 6 is provided with a rubber anti-slip pad. By setting the hydraulic telescopic cylinders 5 and the support plate 6, the height of the device can be adjusted according to actual needs. The rubber anti-slip pad on the bottom surface of the support plate 6 can enhance the stability of the device.

[0023] Example 2: Please see Figure 1-6 In this embodiment, the adjustment component 3 includes a moving block 31, a guide groove 32, a lead screw 33, and a drive motor 34. The moving block 31 is welded to the side surface of the moving plate 21 near the base 1. The side surface of the base 1 has a convex-shaped guide groove 32. The moving block 31 is adapted to the guide groove 32. The lead screw 33 is set in the guide groove 32 on the surface of the base 1. One end of the lead screw 33 is rotatably connected to the base 1, and the other end of the lead screw 33 is connected to the output shaft end of the drive motor 34 installed on the outside of the base 1. By driving the lead screw 33 to rotate through the drive motor 34, the moving block 31 can move in the guide groove 32, thereby adjusting the position of the positioning component 2. This enables rapid and accurate positioning of castings at different positions, greatly improving positioning efficiency.

[0024] The base 1 is also equipped with a control box, which contains a controller. The controller is electrically connected to the hydraulic telescopic cylinder 5, the telescopic air cylinder 22, and the drive motor 34. The electrical connection between the controller and each component realizes the automated control of the positioning device, simplifies the operation process, improves processing efficiency, and reduces labor costs.

[0025] Through the above steps, during use, based on the size and shape of the metal casting body 12, the controller in the control box starts the drive motor 34, and the output shaft of the drive motor 34 drives the lead screw 33 to rotate. When the lead screw 33 rotates, the moving block 31, which is threadedly connected to the lead screw 33 and adapted to the guide groove 32, moves within the guide groove 32, thereby driving the moving plate 21 welded to the moving block 31 to move, adjusting the horizontal position of the positioning component 2, so that the positioning plate 25 and the positioning post 26 approach the part of the metal casting that needs to be positioned; then, the controller controls the telescopic cylinder 22 to work, and the telescopic cylinder 22 pushes the movable plate 23 to rotate around the rotating shaft 24 through the hinge, so that the positioning plate 25 and the positioning post 26 gradually approach the metal casting body 12. When the positioning post 26 contacts the surface of the metal casting, the telescopic cylinder 22 continues to push, so that the anti-slip pad 27 on the positioning post 26 is tightly attached to the metal casting, and the rubber protrusions on the surface of the anti-slip pad 27 increase the friction, so as to achieve precise positioning and stable clamping of the metal casting. Since the positioning column 26 is rotatably mounted on the surface of the positioning plate 25 via bearings, if the metal casting needs to be rotated during subsequent processing, the positioning column 26 can rotate accordingly without affecting the processing operation. During the metal casting processing, the controller monitors the working status of the hydraulic telescopic cylinder 5, the telescopic cylinder 22, and the drive motor 34 in real time to ensure that the positioning device remains stable and that the positioning components do not loosen their position on the metal casting. If an abnormal situation occurs, such as slight displacement of the metal casting during processing, the controller can restart the drive motor 34 and the telescopic cylinder 22 according to the preset program or the operator's instructions to fine-tune the positioning components and re-fix the position of the metal casting, ensuring processing accuracy and quality.

[0026] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
