Description

Technical Field

[0001] This utility model relates to the field of materials testing technology, specifically to a metal materials testing device. Background Technology

[0002] Metal material inspection is a crucial step in verifying whether the quality of materials meets standards through methods such as composition analysis, mechanical property testing, and non-destructive testing. Visual inspection after grinding is one such intuitive method. It requires grinding the surface to remove the oxide layer or contaminants, and then directly observing surface defects such as cracks and inclusions with the naked eye or a low magnification microscope. It is also often used as a pretreatment for surface quality inspection or non-destructive testing and is an important method to ensure the surface quality of materials.

[0003] In existing technologies, when grinding metal materials before inspection, operators usually need to hold the metal material to be inspected and then hold it in direct contact with the grinding equipment. However, when the surface of the metal material has sharp edges or is relatively smooth, it is inconvenient for the operator to fix the metal material. In addition, the metal material heats up after continuous friction during the grinding process, which can easily burn the operator's hands. Therefore, a metal material inspection device is proposed to solve the above problems. Utility Model Content

[0004] The objective of this utility model can be achieved through the following technical solutions: A metal material inspection device includes a grinding mechanism, and a clamping mechanism is provided above the grinding mechanism; The clamping mechanism includes an extension plate, which is L-shaped in general. The upper end of the extension plate extends horizontally. A handle is fixedly connected to one side of the top surface of the extension plate. An inner slide rail is provided in the middle of the top surface of the extension plate. Clamping plates are slidably connected to both ends of the inner wall of the inner slide rail. A buffer pad is glued and fixed between the surfaces of the two clamping plates. A slide rod is fixedly connected to the middle and both sides of the top surface of each clamping plate. A push plate is fixedly installed at the top of the slide rod on the same side. A support spring is sleeved on the outer wall of the middle slide rod on each side.

[0005] As a further embodiment of this utility model: an outer slide rail is provided on the top surface of the extension plate on both sides of the inner slide rail. Both the outer slide rail and the inner slide rail extend in the horizontal direction. A shelf is supported and connected on the top surface of the extension plate above each clamping plate. The bottom center of each shelf is slidably connected along the inner side of the inner slide rail. Each shelf is connected through a slide rod. The top center of each shelf is supported and connected to the bottom of a support spring.

[0006] As a further embodiment of this utility model: a lead screw is rotatably connected to the middle of the upper end of the extension plate, one end of the lead screw is rotatably connected to the surface of one of the shelves, and the other end of the lead screw extends to the outside of the extension plate and is fixedly connected to a knob.

[0007] As a further embodiment of this utility model: threaded shafts are fixedly connected to both sides of the bottom surface of the shelf away from the lead screw. Each threaded shaft extends in a vertical direction and is connected through the inner side of the outer slide rail. A nut is threaded on the outer wall of the threaded shaft below the extension plate. The top surface of the nut abuts against the bottom surface of the extension plate. A limiting base is rotatably connected to the lower end of the extension plate. The upper end of the limiting base is L-shaped and abuts against the lower surface of the extension plate.

[0008] As a further embodiment of this utility model: the grinding mechanism includes an outer shell, a drainage groove is provided on one side of the bottom surface of the inner wall of the outer shell, and a drainage pipe is connected through and fixedly connected to the lower end of the outer wall of the outer shell, with the port of the drainage pipe aligned with the inside of the drainage groove.

[0009] As a further embodiment of this utility model: an annular plate is fixedly installed in the middle of the inner wall of the outer shell, a servo motor is fixedly installed in the middle of the annular plate, and the output shaft of the servo motor faces upward and is fixedly connected to a drive shaft.

[0010] As a further embodiment of this utility model: a turntable is inserted into the outer side of the drive shaft, the bottom surface of the turntable is rotatably connected to the top surface of the annular plate, sandpaper is supported and connected in the middle of the top surface of the turntable, and a pressure plate is inserted into the top surface of the turntable and outside the sandpaper. Several drainage holes are opened on the outer wall of the pressure plate near the top surface of the turntable.

[0011] The beneficial effects of this utility model are: (1) This utility model uses a servo motor-driven turntable to grind metal materials with sandpaper on top. A pressure plate is inserted into the top of the turntable. At the same time, the pressure plate presses down on the sandpaper and assists in positioning. Multiple drainage holes are opened on the outside of the pressure plate. During the grinding of metal materials, a water pipe for conveying water can be placed above the sandpaper to output water to the grinding surface of the metal material and cool it down. This avoids damage to the metal material caused by the high temperature generated during grinding and can also reduce dust from grinding debris. Cooling water falls into the outer shell through the drainage holes and is finally discharged through the drainage pipe.

[0012] (2) A clamping mechanism is installed above the sandpaper. The clamping plates on both sides of the clamping mechanism can clamp and fix the symmetrical sides of the metal material respectively. The surface of the clamping plate is also bonded with a flexible buffer pad. When the cylindrical metal material is clamped, the surface of the buffer pad is concave and wraps around the cylindrical side, thereby increasing the contact area with the metal material and helping to improve the clamping stability. During the grinding, the operator only needs to press down the push plate to drive the two clamping plates to fall slightly and drive the end face of the metal material to fall to receive the sandpaper below. After the grinding is completed, the clamping plate can be flipped by lifting the handle, and the metal material is away from the sandpaper, which makes it convenient for the operator to inspect the ground surface of the metal material.

Figures 3-4 As shown, by rotating the knob 205, the left clamp 208 can be controlled to move horizontally.

[0019] Threaded shafts 213 are fixedly connected to both sides of the bottom surface of the shelf 207 away from the lead screw 206. Each threaded shaft 213 extends vertically and is connected to the inner side of the outer slide rail 203. A nut 214 is threaded onto the outer wall of the threaded shaft 213 below the extension plate 201. The top surface of the nut 214 abuts against the bottom surface of the extension plate 201. A limiting base 215 is rotatably connected to the lower end of the extension plate 201. The upper end of the limiting base 215 is L-shaped and abuts against the lower surface of the extension plate 201. Figures 3-4 As shown, each threaded shaft 213 is inserted into the outer slide rail 203. By tightening the nut 214, the left shelf 207 and clamp 208 are fixed. After loosening the nut 214, the left clamp can move horizontally, which facilitates clamping metal materials of different thicknesses.

[0020] The grinding mechanism 1 includes a housing 101. A drainage groove 102 is provided on one side of the bottom surface of the inner wall of the housing 101. A drainage pipe 103 is passed through and fixedly connected to the lower end of the outer wall of the housing 101. The port of the drainage pipe 103 is aligned with the inside of the drainage groove 102. An annular plate 104 is fixedly installed in the middle of the inner wall of the housing 101. A servo motor 105 is fixedly installed in the middle of the annular plate 104. The output shaft of the servo motor 105 faces upward and is fixedly connected to a drive shaft 106.

[0021] The working principle of this utility model: When the device is in use, the metal material to be inspected is placed on top of the sandpaper 108 and between the two clamping plates 208. Then, the screw 206 is rotated by the knob 205. The screw 206 moves along the threaded hole on the end face of the extension plate 201. The screw 206 pushes the shelf 207 on one side to move along the inner slide rail 204, thereby shortening the distance between the two clamping plates 208 and clamping the metal material. Secondly, the servo motor 105 is started, which drives the turntable 107 to rotate continuously via the drive shaft 106. The sandpaper 108 rotates and polishes the metal material above. During polishing, the operator can press down on the push plate 211, which retracts the support spring 212 and drives the clamping plate 208 to fall through the slide rod 210. The metal material is then clamped and falls against the surface of the sandpaper 108, improving the polishing effect of the sandpaper on the metal material. During polishing, the metal material can be rinsed with water to cool it. The cooling water flows out through the drain hole 110 and then enters the drain groove 102 inside the outer shell 101. Finally, the water flows out through the drain pipe 103. After polishing, the extension plate 201 is rotated 90 degrees clockwise on the limiting base 215 by the handle 202, so that the metal material is removed from the sandpaper 108, making it convenient for the operator to visually inspect the polished surface.
