Description

Technical Field

[0001] The utility model relates to a fixed tool used for grinding small metal die castings, belonging to the technical field of die casting processing. Background Art

[0002] After die casting, metal die castings usually need to be polished and deburred. Currently, manual polishing is mainly used, that is, the worker holds the metal die casting in one hand and the air grinder in the other hand to polish the surface of the metal die casting to remove the burrs on the surface.

[0003] When the metal die castings to be polished are small in size, for example: Figure 1 The end cover of the CNC machining center operation panel shown in the figure not only makes it inconvenient to grasp during manual grinding, but also poses a safety risk of injuring the hands with an air grinder; in addition, if a small metal die-casting is manually held for grinding, there will be a grinding dead angle where the hands grasp, which will result in the need to change the grasping position many times during the grinding process, making the grinding operation very inconvenient and the grinding efficiency very low.

[0023] Example

[0024] Please combine Figures 2 to 6 As shown: This embodiment provides a fixing tool for grinding small metal die castings, including a vertically arranged mounting plate 1, the top of which is horizontally provided with a small metal die casting 2 to be ground (in this embodiment, Figure 1 The end cover of the CNC machining center operation panel shown in the figure is used as an example) and is matched with a contoured adsorption plate 3. The upper part of the contoured adsorption plate 3 is provided with an adsorption groove 31 with a top opening. The adsorption groove 31 is surrounded by a sealing groove 32. A sealing ring 4 is provided in the sealing groove 32. A card groove 5 that is matched with the bottom of the small metal die-casting 2 to be polished is formed between the sealing ring 4 and the adsorption groove 31. An adsorption hole 33 is vertically provided in the adsorption groove 31, and the adsorption hole 33 is connected to a vacuum generator 6 through a pipeline.

[0025] The method of using the fixed tooling for grinding small metal die castings described in the utility model is as follows:

[0026] The small metal die casting 2 to be polished is placed on the top of the profiling adsorption plate 3, and its bottom is stuck in the card slot 5 formed between the adsorption slot 31 of the profiling adsorption plate 3 and the sealing ring 4 (such as Figure 4As shown), in this way, the small metal die-casting 2 to be polished is clamped on the profiling adsorption plate 3, and a chamber is formed between the profiling adsorption plate 3 and the small metal die-casting 2 to be polished; the vacuum generator 6 is turned on, and a negative pressure is generated in the chamber between the profiling adsorption plate 3 and the small metal die-casting 2 to be polished through the vacuum generator 6, so that under the action of the negative pressure, the small metal die-casting 2 to be polished is adsorbed and fixed on the profiling adsorption plate 3; then the staff only needs to hold the air grinder to polish the surface of the small metal die-casting 2 to be polished. After the polishing is completed, the vacuum generator 6 is turned off and the polished small metal die-casting 2 is taken away.

[0027] As can be seen from the above, the utility model can make the small metal die-casting 2 to be polished be clamped on the profiling adsorption plate 3 through the unique setting of the profiling adsorption plate 3 and the sealing ring 4, so that the small metal die-casting 2 to be polished can be fixed in the horizontal direction; and the vacuum generator 6 is used to generate negative pressure in the chamber between the profiling adsorption plate 3 and the small metal die-casting 2 to be polished, and the small metal die-casting 2 to be polished is adsorbed and fixed on the profiling adsorption plate 3 through the negative pressure, so that the small metal die-casting 2 to be polished can be fixed in the vertical direction. In this way, the fixing tool of the utility model can stably fix the small metal die-casting 2 to be polished in the horizontal and vertical directions. In this way, when grinding the small metal die-casting 2 to be ground, the staff does not need to grab the small metal die-casting 2 to be ground, and only needs to hold the air grinder to grind the small metal die-casting 2 to be ground, which effectively overcomes the defects of inconvenient grabbing and poor safety of the traditional small metal die-casting 2 held manually; at the same time, the bottom of the small metal die-casting 2 to be ground is fixedly adsorbed on the contoured adsorption plate 3, and the surface of the small metal die-casting 2 to be ground that needs to be ground is completely exposed, and there is no grinding dead angle. After the small metal die-casting 2 to be ground is fixed, it can be directly ground by the grinder, which can effectively avoid the problem of grinding dead angles, and the grinding operation is very convenient and safe.

[0028] In this embodiment, the top height of the sealing groove 32 is lower than the top height of the adsorption groove 31 , so that it is convenient to install the sealing ring 4 in the sealing groove 32 while forming a clamping groove 5 between the sealing ring 4 and the adsorption groove 31 .

[0029] In this embodiment, please combine Figure 2 and Figure 3As shown, one path of the vacuum generator 6 is connected to the adsorption hole 33 through a pipeline, and the other path of the vacuum generator 6 is connected to the compressed air (omitted in the figure) through a pipeline. A switch valve 7 is provided on the pipeline between the vacuum generator 6 and the compressed air (the compressed air and the pipeline between the compressed air and the switch valve 7 are omitted in the figure). The switch valve 7 controls the on-off of the air path between the vacuum generator 6 and the compressed air, and then controls the switch of the vacuum generator 6. The switch valve 7 can be a commercially available manual valve, and the switch of the vacuum generator 6 is manually controlled by the manual valve.

[0030] In this embodiment, please combine Figure 2 and Figure 3 As shown, a notch is provided at the top of the mounting plate 1 corresponding to the position of the adsorption hole 33 of the contoured adsorption plate 3, leaving space for installing the pipeline at the bottom of the contoured adsorption plate 3, so that the adsorption hole 33 can be connected to the pipeline. The notch can be U-shaped, that is, the mounting plate 1 as a whole is similar to a U-shaped plate.

[0031] In this embodiment, please combine Figure 2 and Figure 3 As shown, the fixing tool further includes a bottom plate 8 arranged horizontally, and the mounting fixing plate 1 and the vacuum generator 6 are both mounted on the bottom plate 8. Correspondingly, the switch valve 7 is also mounted on the bottom plate 8. The bottom plate 8 is used to integrate the related components in the fixing tool on the bottom plate 8.

[0032] In addition, handles 9 are provided on both sides of the top of the bottom plate 8 , so as to facilitate moving and fixing the tooling through the handles 9 .

[0033] Finally, it is necessary to point out that the above is only a preferred specific implementation method of the utility model, but the protection scope of the utility model is not limited to this. Any changes or substitutions that can be easily thought of by any technician familiar with the technical field within the technical scope disclosed by the utility model should be covered within the protection scope of the utility model.
