Description

Technical Field

[0001] This utility model relates to the field of aluminum profile processing technology, and in particular to a weld seam treatment device for aluminum profile frames. Background Technology

[0002] Aluminum profile frames are structural components made of aluminum alloy. Due to their lightweight, high strength, corrosion resistance, and ease of processing, they are widely used in industries, transportation, and construction. During their production, welding is usually required to fix the various parts of the frame. To further improve the flatness, aesthetics, and structural stability of the frame, the welds produced after welding need to be professionally ground.

[0003] An automated welding device for metal door and window processing is disclosed in Chinese Patent Publication No. CN223172423U. This automated welding device for metal door and window processing can control the linear reciprocating motion of the grinding wheel during grinding, thereby improving the grinding effect of the grinding wheel. However, according to the automated welding device for metal door and window processing provided by related technologies and existing technologies: traditional aluminum frame grinding requires separate treatment of the upper and lower surfaces and corners of the aluminum frame. Multiple clamping and adjustment affect the overall grinding speed. At the same time, corner grinding is mostly done manually by holding the grinding tool or pushing the aluminum frame to adapt to the corner contour. However, it is difficult to accurately control the force, speed and path stability of manual operation, which affects the accuracy of corner grinding. In addition, traditional flat surface grinding relies on the linear motion of a fixed grinding disc, which is prone to producing striped grinding marks, affecting the effect of flat surface grinding.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0024] Additional aspects and advantages of this invention will be further set forth in the description which follows in conjunction with the accompanying drawings, in part of which will be obvious from the description or may be learned by practice of the invention.

[0025] like Figures 1 to 7As shown, a welding treatment device for an aluminum profile frame includes a frame 1. A lifting assembly 3 is located at the top of the frame 1, and a lifting frame 8 is mounted on the lifting assembly 3. A grinding assembly 5 for simultaneously grinding both sides and corners of the aluminum frame is located inside the lifting frame 8. A swing assembly 6 for controlling the swing of the grinding assembly 5 to grind the corners is located at the top of the lifting frame 8. A grinding table 2 is fixedly mounted on the frame 1 corresponding to the position of the grinding assembly 5. A fixing assembly 4 for limiting and fixing the aluminum frame is mounted on the grinding table 2. In use, the fixing assembly 4 of the aluminum frame is fixedly positioned on the grinding table 2, and then the grinding assembly 5... Upon startup, the lifting assembly 3 controls the grinding assembly 5 to first contact the upper surface of the aluminum frame and grind its upper surface and corners. After the upper surface is ground, the grinding assembly 5 contacts the lower surface of the aluminum frame and grinds its lower surface and remaining corners. Thus, the grinding of both sides and corners of the aluminum frame is achieved in one processing step, greatly improving the overall grinding speed. In addition, during the grinding process, the swing assembly 6 controls the grinding assembly 5 to swing around the corner line, thereby uniformly grinding the corners of the aluminum frame and forming a composite grinding trajectory, which greatly improves the uniformity of surface grinding.

[0026] like Figure 3 As shown, the lifting assembly 3 includes a vertical rail 31 fixed to the top of the frame 1. A lifting drive component 32 is fixedly installed on the top of the vertical rail 31. A lead screw 33 is fixedly installed at the output end of the lifting drive component 32. The lead screw 33 is rotatably installed inside the vertical rail 31. The lifting frame 8 is threadedly connected to the lead screw 33 and slidably connected to the vertical rail 31. The lifting drive component 32 drives the lead screw 33 to rotate. Since the lifting frame 8 is threadedly connected to the lead screw 33 and slidably engaged with the vertical rail 31, the rotational motion of the lead screw 33 is converted into the linear lifting motion of the lifting frame 8 along the vertical rail 31, thereby realizing the adjustment of the grinding height.

[0027] like Figure 1 and Figure 2 As shown, the fixing component 4 includes a fixing frame 41 fixed to the top of the grinding table 2. An electric push rod 43 is fixedly installed on the top of the fixing frame 41. The output end of the electric push rod 43 passes downward through the fixing frame 41 and is fixedly provided with a pressure plate 42. The pressure plate 42 is vertically slidably connected to the fixing frame 41. The grinding table 2 is symmetrically provided with two positioning plates 44 below the pressure plate 42 to limit the position of the aluminum frame. The two positioning plates 44 are set perpendicular to each other. The electric push rod 43 extends and pushes the pressure plate 42 to move downward. In conjunction with the two positioning plates 44 on the grinding table 2, the aluminum frame is limited and fixed from the vertical and horizontal: the positioning plate 44 limits the horizontal position of the aluminum frame, and the pressure plate 42 presses the aluminum frame tightly on the grinding table 2 to prevent the aluminum frame from shifting during the grinding process.

[0028] like Figure 3 and Figure 4As shown, the swing assembly 6 includes a swing drive 61 fixed to the top of the lifting frame 8. A crank 62 is fixedly provided at the output end of the swing drive 61. A connecting rod 63 is hinged to the end of the crank 62. A rocker arm 64 is hinged to the end of the connecting rod 63 away from the crank 62. The swing drive 61 drives the crank 62 to rotate. The crank 62 pushes the rocker arm 64 to swing back and forth through the connecting rod 63. The rocker arm 64 is connected to the grinding assembly 5, thereby driving its swing.

[0029] like Figures 3 to 7 As shown, the grinding assembly 5 includes a grinding frame 51 installed inside the lifting frame 8. A vertically arranged main shaft 52 is rotatably mounted on the grinding frame 51. A grinding roller 54 for grinding the edges and corners of the aluminum frame is fixedly mounted on the main shaft 52. A grinding drive component 53 for driving the main shaft 52 to rotate is fixedly mounted on the top of the grinding frame 51. Grinding discs 56 for grinding both sides of the aluminum frame are provided at both ends of the grinding roller 54 on the grinding frame 51. The grinding discs 56 and the grinding frame 51 are connected by a secondary shaft 55. The connection is as follows: each secondary shaft 55 is driven to the main shaft 52 via a synchronous belt 57; the grinding frame 51 and the lifting frame 8 are rotatably connected via a rotating shaft 7; the end of the rocker arm 64 away from the connecting rod 63 is fixedly connected to the rotating shaft 7; the axis of the rotating shaft 7 coincides with the corner line of the aluminum frame; the grinding drive component 53 drives the main shaft 52 to rotate, and the main shaft 52 drives the secondary shafts 55 at both ends to rotate synchronously via the synchronous belt 57, so that the grinding roller 54 on the main shaft 52 and the grinding disc 56 on the secondary shaft 55 work simultaneously. The grinding roller 54 focuses on grinding the edges and corners of the aluminum frame, while the grinding disc 56 is responsible for the flat surface treatment of the upper and lower surfaces of the aluminum frame, achieving simultaneous processing of both surfaces and edges and corners, greatly improving the grinding speed. Meanwhile, the grinding frame 51 is rotatably connected to the lifting frame 8 via a rotating shaft 7, and the axis of the rotating shaft 7 coincides with the edge and corner line of the aluminum frame (i.e., the swing center is coaxial with the edge and corner line). When the connecting rod 63 of the swing assembly 6 pushes the rocker arm 64, the rocker arm 64 drives the rotating shaft 7 to reciprocate around the edge and corner line of the aluminum frame, thereby... The entire grinding frame 51 and grinding roller 54 swing in an arc around the corner line. While rotating, the grinding roller 54 swings with the grinding frame 51. Its motion trajectory matches the contour of the aluminum frame corner, achieving uniform grinding of the corner area. In addition, when grinding both sides, the grinding disc 56 also swings with the grinding frame 51. The swinging motion of the grinding disc 56 (around the corner line) and its own rotational motion (around the secondary shaft 55) form a compound motion trajectory, thereby improving the uniformity of grinding on both sides.

[0030] The work process is as follows:

[0031] S1: As Figure 4 As shown, the grinding drive 53 drives the main shaft 52 to rotate, and the main shaft 52 drives the auxiliary shafts 55 at both ends to rotate synchronously through the timing belt 57, so that the grinding roller 54 on the main shaft 52 and the grinding disc 56 on the auxiliary shaft 55 work at the same time.

[0032] S2: As Figures 1 to 3As shown, the aluminum frame is placed on the grinding table 2, so that the two sides of the aluminum frame are in contact with the positioning plate 44 for initial positioning. During this process, the corners of the aluminum frame contact the grinding roller 54 to achieve initial grinding, ensuring that the aluminum frame can be in close contact with the positioning plate 44 to achieve positioning.

[0033] S3: As Figure 1 As shown, when the electric push rod 43 is activated, it pushes the pressure plate 42 downward and presses the top of the aluminum frame. Through the cooperation of the positioning plate 44 and the pressure plate 42, the aluminum frame is firmly fixed on the grinding table 2 to prevent displacement during grinding.

[0034] S4: As Figure 3 and Figure 5 As shown, the lifting drive component 32 drives the lead screw 33 to rotate, causing the lifting frame 8 to slide down along the vertical rail 31, so that the upper grinding disc 56 descends to contact the upper surface of the aluminum frame and grinds the weld seam on its upper surface.

[0035] S5: As Figure 6 and Figure 7 As shown, at the same time, the swing drive 61 drives the crank 62 to rotate, and the crank 62 pushes the rocker arm 64 to swing back and forth through the connecting rod 63, which in turn drives the grinding frame 51 through the rotating shaft 7 to drive the grinding roller 54 to swing periodically along the corner of the aluminum frame, so as to achieve uniform grinding of the corner area.

[0036] S6: As Figure 6 and Figure 7 As shown, in addition, when the grinding disc 56 is grinding the surface, it will also swing along with the grinding frame 51. The swinging motion of the grinding disc 56 and its own rotational motion form a compound motion trajectory, thereby improving the uniformity of grinding on both sides.

[0037] S7: As Figure 4 As shown, after the upper surface of the aluminum frame is polished, the polishing frame 51 moves upward to drive the polishing disc 56 below to fit against the lower surface of the aluminum frame. The lower surface of the aluminum frame is polished through the above process. At the same time, the polishing roller 54 covers all areas of the corners of the aluminum frame to achieve polishing of the corners without dead angles.

[0038] S8: As shown in 3, the above design allows for the grinding of both sides and corners of the aluminum frame in a single process, eliminating the need for step-by-step processing and significantly improving grinding speed. In addition, the oscillating grinding design not only allows for uniform grinding of the aluminum frame corners but also enables the grinding disc 56 to form a composite grinding trajectory, greatly improving the uniformity of grinding.

[0039] In this application, all driving components are electric motors, which, along with the electric push rod 43, are known technologies in this field. Therefore, their specific structures and working principles are not described in detail.

[0040] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
