Description

Technical Field

[0001] The utility model relates to the technical field of gravity casting, in particular to a clamping tool for detecting a gravity casting workpiece. Background Art

[0002] Gravity casting refers to the process of pouring molten metal into a mold under the action of the earth's gravity, also known as gravity casting. In a broad sense, gravity casting includes sand casting, metal mold casting, investment casting, lost foam casting, mud mold casting, etc. In a narrow sense, gravity casting mainly refers to metal mold casting. After gravity casting, the workpiece needs to be further tested to ensure the casting quality of the workpiece. When testing the workpiece, it is necessary to clamp and fix the workpiece with a clamping tool to facilitate the inspection of the workpiece.

[0003] However, the existing workpiece clamping method mainly fixes the workpiece by extrusion. Since some workpieces have different shapes and the surface of the fixing workpiece in contact with the workpiece is relatively flat, only the most protruding part of the workpiece can be clamped during extrusion fixation. The actual contact area between the clamping component and the workpiece is small, the clamping stability is poor, and the workpiece is easy to fall off when subjected to external force. Since the workpiece falls off during inspection, it is easy to cause damage to the workpiece, and the fallen workpiece may also injure the staff. Utility Model Content

[0012] 1. In the utility model, when working, the workpiece to be inspected is placed on the fixed plate on the inner wall of the bottom of the mounting frame, and then the threaded rod is rotated. The threaded rod descends and drives the fixed plate to descend. The fixed plate installed at the bottom of the fixed plate gradually squeezes the top of the workpiece. As the fixed plate contacts the workpiece, the spring gradually contracts under pressure. Due to the irregular shape of the workpiece, the degree of contraction of each spring is different. Compared with the traditional workpiece clamping device, it can fix different positions of irregular workpieces, the fixed clamping area is larger, and the force on the workpiece is more uniform, making the workpiece more stable during inspection, not easy to shake or fall off, and more convenient to use. The pressure sensor monitors the pressure on the workpiece. When the pressure reaches a certain value, the prompt light lights up, indicating that the pressure on the workpiece reaches a certain value. Under this pressure value, the workpiece is stably fixed and cannot shake. The anti-slip pad increases the friction between the fixed plate and the workpiece, making the workpiece more stable.

[0013] 2. In the utility model, when clamping a workpiece, the first electric telescopic rod drives the clamping components to move closer to or farther from each other, and the spacing between the clamping components is adjusted according to the length of the workpiece to be fixed, so as to facilitate the fixing of workpieces of different specifications and sizes. The servo motor drives the rotating disk to rotate and drive the clamping components and the workpiece to flip, so as to facilitate the detection of the other side of the workpiece, which is more convenient to use. When inspecting the workpiece, the second electric telescopic rod drives the support plate to rise to support the bottom of the workpiece, thereby reducing the load of the clamping components and preventing the clamping components from malfunctioning due to excessive load. At the same time, the support component supports the workpiece, making the workpiece more stable, which is conducive to workpiece detection. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] By means of the above structure: during operation, the workpiece to be inspected is placed on the fixed plate 7 on the inner wall at the bottom of the mounting frame 2, and then the threaded rod 3 is rotated. The threaded rod 3 descends and drives the fixed plate 4 to descend, and the fixed plate 7 installed at the bottom of the fixed plate 4 gradually squeezes the top of the workpiece. As the fixed plate 7 contacts the workpiece, the spring 8 is gradually compressed and contracts. Due to the irregular shape of the workpiece, the degree of contraction of each spring 8 is different. Compared with the traditional workpiece clamping device, it can fix different positions of irregular workpieces, the fixed clamping area is larger, and the force on the workpiece is more uniform, making the workpiece more stable during inspection, not easy to shake or fall off, and more convenient to use. The pressure sensor 10 monitors the pressure on the workpiece. When the pressure reaches a certain value, the prompt light 11 lights up, indicating that the pressure on the workpiece reaches a certain value. Under this pressure value, the workpiece is stably fixed and cannot shake.

[0023] like Figure 4 As shown, anti-skid pads 9 are provided between the adjacent outer walls of the fixed plate 7. The anti-skid pads 9 are adapted to the fixed plate 7. The thickness of the anti-skid pads 9 is less than that of the fixed plate 7. The anti-skid pads 9 increase the friction between the fixed plate 7 and the workpiece, making the workpiece more stable.

[0024] like Figure 1As shown, the mounting assembly includes mounting rods 15 welded to both ends of the outer wall at the top of the base plate 1, and the outer walls on both adjacent sides of the mounting rods 15 are provided with rotating grooves, and a rotating disk 12 is rotatably installed on the inner wall of the rotating groove, and a first electric telescopic rod 13 is installed on the outer wall of the rotating disk 12, and the first electric telescopic rod 13 is connected to the mounting frame 2. A servo motor 14 is installed on the outer wall of the mounting rod 15 on one side by bolts, and the output shaft of the servo motor 14 is connected to the rotating disk 12, and the servo motor 14 is provided with a protective cover adapted thereto. When the workpiece is clamped, the first electric telescopic rod 13 drives the clamping assemblies to move closer to or away from each other, and the spacing of the clamping assemblies is adjusted according to the length of the workpiece to be fixed, so as to facilitate the fixing of workpieces of different specifications and sizes, and the servo motor 14 drives the rotating disk 12 to rotate and drive the clamping assembly and the workpiece to flip, so as to facilitate the detection of the other side of the workpiece, and it is more convenient to use.

When the workpiece is inspected, the second electric telescopic rod 16 drives the support plate 17 to rise to support the bottom of the workpiece, reduce the load of the clamping assembly, and prevent the clamping assembly from malfunctioning due to excessive load. At the same time, the support assembly supports the workpiece, making the workpiece more stable, which is conducive to workpiece inspection.

[0026] How this utility works:

[0027] During operation, the workpiece to be inspected is placed on the fixed plate 7 on the inner wall at the bottom of the mounting frame 2, and then the threaded rod 3 is rotated. The threaded rod 3 descends and drives the fixed plate 4 to descend. The fixed plate 7 installed at the bottom of the fixed plate 4 gradually squeezes the top of the workpiece. As the fixed plate 7 contacts the workpiece, the spring 8 is gradually compressed and contracted. Due to the irregular shape of the workpiece, the degree of contraction of each spring 8 is different. Compared with the traditional workpiece clamping device, it can fix different positions of irregular workpieces, the fixed clamping area is larger, and the force on the workpiece is more uniform, making the workpiece more stable during inspection, not easy to shake or fall off, and more convenient to use. The pressure sensor 10 monitors the pressure on the workpiece. When the pressure reaches a certain value, the warning light 11 lights up, indicating that the pressure on the workpiece reaches a certain value. At this pressure value, the workpiece is stably fixed and cannot shake. The anti-slip pad 9 increases the friction between the fixed plate 7 and the workpiece, making the workpiece more stable.

[0028] When clamping the workpiece, the first electric telescopic rod 13 drives the clamping components to move closer to or farther away from each other, and the spacing between the clamping components is adjusted according to the length of the workpiece to be fixed, so as to facilitate the fixing of workpieces of different specifications and sizes. The servo motor 14 drives the rotating disk 12 to rotate and drive the clamping components and the workpiece to flip, so as to facilitate the detection of the other side of the workpiece, which is more convenient to use. When inspecting the workpiece, the second electric telescopic rod 16 drives the support plate 17 to rise to support the bottom of the workpiece, thereby reducing the load of the clamping components and preventing the clamping components from malfunctioning due to excessive load. At the same time, the support component supports the workpiece, making the workpiece more stable, which is conducive to workpiece inspection.
