Description

Technical Field

[0001] This utility model relates to the field of workpiece machining technology, and in particular to a support mechanism for machining. Background Technology

[0002] Currently, hydraulic fixtures are commonly used for positioning and supporting workpieces during machining. Traditional support methods often employ a support cylinder positioned directly below the workpiece clamping point for direct support. However, when the workpiece's machining features are close to the support point, the support cylinder itself encroaches on the tool's path. In other words, traditional support mechanisms using direct cylinder support interfere with the tool, making machining of the corresponding features more difficult. Summary of the Invention

[0003] The technical problem to be solved by this utility model is to provide a simple support mechanism for machining, which is suitable for use in machining scenarios where the machining features of the workpiece are close to the support point, so as to facilitate the machining of the corresponding features.

[0004] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows: A machining support mechanism includes a support cylinder, a support plate, and a fixed base. The two opposite ends of the support plate are a support end and a mounting end, respectively. The mounting end is rotatably mounted on the fixed base, allowing the support end to tilt up and down. The support cylinder has a push rod that can extend and retract up and down. The push rod pushes upward and acts on the lower end face of the support plate, causing the support end to support the workpiece upward. The push rod is disposed between the support end and the mounting end.

[0005] The fixed base is provided with two rotating mounting walls, and there is a mounting groove between the two rotating mounting walls for the mounting end to be inserted and installed. Each of the two rotating mounting walls is provided with a through mounting hole, and the two mounting holes are coaxially arranged. The mounting end is provided with a matching rotating mounting hole. The support plate is rotated and installed on the rotating mounting base by a rotating shaft passing through the mounting hole on one rotating mounting wall, the rotating mounting hole and the mounting hole on the other rotating mounting wall in sequence. The rotating mounting hole and the rotating shaft are in clearance fit.

[0006] Both ends of the rotating shaft extend outwards, and the extended portion of the rotating shaft is provided with a retaining ring groove. The rotating shaft is secured to the fixed base by a matching retaining ring that is locked in the corresponding retaining ring groove.

[0007] The fixed base is provided with a limiting mechanism to prevent the support plate from rotating excessively.

[0008] The limiting mechanism includes a horizontally arranged limiting plate, which is spaced apart above the two rotating mounting walls.

[0009] One end of the limiting plate is bent vertically downward to form a support wall. The support wall is located behind the two rotating mounting walls. A horizontal connecting wall protrudes from the support wall toward the support end. The connecting wall is detachably and fixedly mounted on the fixed base.

[0010] The connecting wall is provided with a vertically penetrating connecting hole, and the fixing base is provided with a corresponding mounting screw hole. The connecting wall is detachably fixed on the fixing base by passing a matching screw through the connecting hole and screwing it into the corresponding mounting screw hole.

[0011] The connecting hole is a waist-shaped hole, and the length direction of the waist-shaped hole is from the support end to the mounting end. The length of the waist-shaped hole is greater than the width of the waist-shaped hole.

[0012] Compared with the prior art, the advantages of this utility model are as follows: It has a simple structure. By placing the push rod of the support cylinder between the support end and the mounting end of the support plate, the lever principle is used to tilt the support end upwards to support it below the workpiece. This allows the support cylinder body to avoid the workpiece's machining area, fundamentally solving the tool path interference problem caused by the traditional direct support of the support cylinder when the workpiece's machining features are close to the support point. Furthermore, the support cylinder and support plate are two independent components, requiring no fixed connection. The original structure of the support cylinder as a standard part is retained, eliminating the need for any modifications, reducing manufacturing and maintenance costs, and improving the versatility and adaptability of the mechanism.

[0014] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0015] As shown in the figure, a support mechanism for machining includes a support cylinder 1, a support plate 2, and a fixed base 3. The two opposite ends of the support plate 2 are a support end 21 and a mounting end 22, respectively. The mounting end 22 is rotatably mounted on the fixed base 3, so that the support end 21 can tilt up and down. The support cylinder 1 has a push rod 11 that can extend and retract up and down. The push rod 11 pushes upward and acts on the lower end surface of the support plate 2, driving the support end 21 to support the workpiece upward. The push rod 11 is located between the support end 21 and the mounting end 22.

[0016] In this specific embodiment, the fixed base 3 is provided with two rotating mounting walls 31, and a mounting groove 32 for the mounting end 22 to be inserted between the two rotating mounting walls 31. Each of the two rotating mounting walls 31 has a through mounting hole 311, which is coaxially arranged. The mounting end 22 has a matching rotating mounting hole 221. A rotating shaft 4 passes sequentially through the mounting holes 311, 221, and 311 on one rotating mounting wall 31, enabling the support plate 2 to be rotated on the rotating mounting base. The rotating mounting hole 221 is clearance-fitted with the rotating shaft 4. The cooperation of the double mounting walls and the rotating shaft 4 provides a stable and precise rotation axis 4 for the support plate 2; the clearance fit between the rotating shaft 4 and the rotating mounting hole 221 ensures that the support plate 2 can tilt flexibly and smoothly.

[0017] In this specific embodiment, both ends of the rotating shaft 4 extend outwards, and the extended portion of the rotating shaft 4 is provided with a retaining spring groove 41. The retaining spring 5 is engaged in the corresponding retaining spring groove 41 to achieve anti-detachment installation of the rotating shaft 4 on the fixed base 3. The structure is simple, the installation is reliable and stable, and it is easy to disassemble and assemble, enabling quick installation and replacement of the support plate 2.

[0018] In this specific embodiment, the fixed base 3 is provided with a limiting mechanism to prevent the support plate 2 from rotating excessively. The limiting mechanism effectively prevents the support plate 2 from accidentally flipping 180° to another direction, thereby avoiding interference or collision with surrounding components and protecting the mechanism itself.

[0019] In this specific embodiment, the limiting mechanism includes a horizontally arranged limiting plate 6, which is spaced apart above the two rotating mounting walls 31. The structure is simple; the horizontal limiting plate 6, spaced apart above the rotating mounting walls 31, effectively limits the rotation angle of the support plate 2. The specific angle can be adjusted by the gap between the limiting plate 6 and the rotating mounting walls 31.

[0020] In this specific embodiment, one end of the limiting plate 6 is bent downwards vertically to form a support wall 61. The support wall 61 is located behind the two rotating mounting walls 31. A horizontal connecting wall 62 protrudes from the support wall 61 toward the support end 21. The connecting wall 62 is detachably and fixedly mounted on the fixed base 3. The structure is simple, providing lateral support strength through the support wall 61 and facilitating convenient connection with the fixed base 3 through the horizontal connecting wall 62.

[0021] In this specific embodiment, the connecting wall 62 is provided with a vertically penetrating connecting hole 621, and the fixing base 3 is provided with a corresponding mounting screw hole 33. The connecting wall 62 is detachably fixedly installed on the fixing base 3 by passing through the connecting hole 621 and screwing it into the corresponding mounting screw hole 33. The structure is simple and easy to assemble and disassemble.

[0022] In this specific embodiment, the connecting hole 621 is an oblong hole, with its length extending from the support end 21 to the mounting end 22. The length of the oblong hole is greater than its width. The oblong hole design provides adjustment margin, allowing the position of the limiting plate 6 to be finely adjusted. This enables adjustment of the upward tilting stroke of the support end 21, enhancing the overall flexibility of the mechanism's installation and its adaptability to tolerances.
