Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of part surface grinding quality inspection, in particular to a grinding quality inspection tool. Background Art
[0002] When producing sheet metal parts through stamping process, the stamping process includes shearing, punching, cutting, compounding, folding, welding, riveting, splicing, forming and other processes. If there is a processing error in the stamping process, it is easy to cause defects on the surface of the sheet metal. Therefore, after the sheet metal processing is completed, the sheet metal parts need to be inspected to ensure that the sheet metal products meet the size requirements and other requirements.
[0003] In order to make sheet metal parts reach qualified standards, the flatness of the surface of sheet metal parts is usually inspected. The operator grinds the surface of the sheet metal parts with the sand net on the grinding tool, and then manually observes the surface of the sheet metal parts to determine whether there are defects such as pitting and indentation on the surface of the sheet metal parts.
[0004] However, when the operator is grinding the tool, if the grinding tool is pressed down on the sheet metal part for grinding, the sheet metal part is likely to be deformed due to the force, and the operator needs to manually hold the moving parts on the production line tightly, which may easily cut the operator if the operation is improper. If the sheet metal part is not pressed tightly during grinding, the sand screen will not fit the surface of the sheet metal part well, affecting the grinding effect. In view of this, it is necessary to provide a grinding quality inspection tool that can take into account both safety and grinding effect. Utility Model Content
[0005] The purpose of the utility model is to provide a polishing quality inspection tool, in which a sand net is arranged on the lower surface of an elastic body, and the surface of a part is rubbed by the soft sand net supported by the elastic body, and a magnet in the elastic body attracts the part so that the part is tightly attached to the sand net, so that an operator can polish the surface of the part more easily, and the final polishing effect also meets the quality inspection requirements, and the operator is safer during the polishing quality inspection process, and after the operator's hands do not need to directly contact the parts on the production line, the flow speed of the production line can be faster, thereby improving production efficiency.
[0006] The technical solution of the utility model provides a polishing quality inspection tool, comprising an elastic body and a sand net connected to the lower surface of the elastic body;
[0007] Wherein, a magnet for adsorbing ferromagnetic parts is arranged in the elastic body.
[0008] In one of the optional technical solutions, the magnet includes a plurality of magnetic units, and the plurality of magnetic units are evenly distributed in the elastic body.
[0009] In one of the optional technical solutions, the elastic body is in a cylindrical structure, and the plurality of magnetic units are evenly distributed along the circumference of the elastic body.
[0010] In one of the optional technical solutions, the elastic body has a plurality of assembly grooves uniformly distributed along the circumference and opening upward, and the magnetic unit is detachably embedded in the assembly grooves.
[0011] In one of the optional technical solutions, the magnet includes at least one magnetic unit in a circular shape, and the magnetic unit is parallel to the sand screen.
[0012] In one of the optional technical solutions, the magnetic unit is a permanent magnet, or the magnetic unit is an electromagnet.
[0013] In one of the optional technical solutions, the elastic body includes a fixed plate, a sponge layer and a pad which are stacked in sequence from top to bottom, the sand net is connected to the lower surface of the pad, and the magnet is connected to the lower surface of the fixed plate.
[0014] In one of the optional technical solutions, a hand-held portion is provided on the fixed plate.
[0015] In one of the optional technical solutions, the hand-held part includes an elastic band, and two ends of the elastic band are respectively fixedly connected to the fixing plate.
[0016] In one of the optional technical solutions, Velcro is provided on two opposite sides of the sand net, and the sand net is detachably connected to the elastic body through the Velcro.
[0017] The above technical solution has the following beneficial effects:
[0018] The grinding quality inspection tool provided by the utility model includes an elastic body and a sand net. By arranging the sand net on the lower surface of the elastic body, the elastic body can support the sand net, so that the sand net can softly fit and grind the surface of the parts. A magnet is arranged in the elastic body, so that the magnet actively attracts the parts, and the parts are actively attached to the sand net after being attracted. The operator's hands do not need to directly contact the parts on the production line, and the flow speed of the production line can be faster to improve production efficiency. Because the parts are actively attached to the sand net under the action of the magnet, the grinding effect can meet the quality inspection requirements without the operator holding the parts with his hands, which greatly improves the safety of the operator in the grinding quality inspection process after the sheet metal processing is completed.

[0025] The specific implementation of the utility model is further described below in conjunction with the accompanying drawings. The same parts are represented by the same figure numbers. It should be noted that the words "front", "rear", "left", "right", "upper" and "lower" used in the following description refer to directions in the accompanying drawings, and the words "inner" and "outer" refer to directions toward or away from the geometric center of a specific component, respectively.
[0026] like Figure 1-4 As shown, a polishing quality inspection tool provided by an embodiment of the utility model comprises an elastic body 1 and a sanding net 2 connected to the lower surface of the elastic body 1. Among them, a magnet 3 for adsorbing ferromagnetic parts is provided in the elastic body 1. The function of the magnet 3 is to adsorb the ferromagnetic parts and make the ferromagnetic parts close to the sanding net 2 located on the lower surface of the elastic body 1.
[0027] Since sheet metal parts are stamped and formed, especially the parts on automobiles, stamping and forming are often used, the sheet metal parts obtained after shearing, punching, cutting, compounding, folding, welding, riveting, splicing, forming and other processing need to be inspected for quality to ensure that the quality of the parts is qualified and can be installed on the car. In the existing automobile sheet metal parts production line, the operator generally uses a grinding tool to grind the surface of the parts after stamping and then observes the surface of the parts after grinding to ensure that there are no obvious defects on the surface of the parts, and then the parts pass the quality inspection. However, since the parts flowing on the production line are not easy to grind, and the edges of some sheet metal parts are relatively sharp, it is easy to cut the hands of the operator. For this reason, the grinding quality inspection tool provided by the technical solution is provided with a magnet 3, and the way of actively adsorbing the parts to be inspected by the magnet 3 replaces the way of the operator manually fitting the sheet metal parts with the quality inspection grinding tool, so as to ensure the safety of the operator during the grinding quality inspection process, and at the same time, it can also speed up the transportation speed of the parts on the production line.
[0028] like Figure 1 and Figure 3 As shown, specifically, the elastic body 1 is the main part of the grinding quality inspection tool, which occupies most of the volume, and plays the role of installing the sand net 2, providing the operator with hand-held, buffering the impact of the grinding process, and making the sand net 2 fit the surface of various structural parts. Therefore, the elastic body 1 itself must have a certain elasticity. Based on the elasticity of the elastic body 1 itself, the sand net 2 on the lower surface of the elastic body 1 is completely covered on the surface of the part, and the impact generated by the operator's grinding action is absorbed, so that the surface of the sheet metal part can be gently and comprehensively polished.
[0029] The elastic body 1 is a block structure, and the elastic body 1 as a whole can be a regular structure such as a rectangular structure, a cylindrical structure, or other irregular structures, which will not be repeated here. In order to meet the elastic requirements of the elastic body 1, the material made of the elastic body 1 can be one or more elastic materials such as sponge materials, rubber materials or silicone materials. In order to improve the uniformity of polishing the surface of the part, the elastic body 1 is preferably a cylindrical structure, and accordingly, the sand net 2 is also a circular structure that matches the circular surface of the elastic body 1. The sand net 2 is fitted and connected to the circular surface of the elastic body 1, and cooperates with the internal magnet 3 to adsorb the part to evenly polish the surface of the part.
[0030] Here, the parts that can be magnetically attracted by the magnet 3 can only be made of ferromagnetic materials such as iron, cobalt, nickel and their alloys and ferrite. When the grinding quality inspection tool is used to grind parts made of non-ferromagnetic materials, it is also possible to grind directly by pressing the surface of the parts without magnetically attracting the parts.
[0031] The connection between the sand screen 2 and the elastic body 1 can be a fixed connection or a detachable connection for easy replacement. The sand screen 2 is a sandpaper or metal mesh with a grid. The rough surface of the sand screen 2 can polish the surface of the part, eliminate the debris and fine concave-convex structure on the surface of the part, make the surface of the part smooth, and facilitate the observation of defects on the surface of the part.
[0032] The grinding quality inspection tool provided by the utility model includes an elastic body 1 and a sand net 2. The sand net 2 is arranged on the lower surface of the elastic body 1, so that the elastic body 1 can support the sand net 2, so that the sand net 2 can softly fit and grind the surface of the parts. A magnet 3 is arranged in the elastic body 1, so that the magnet 3 actively attracts the parts, and the parts are actively attached to the sand net 2 after being attracted. The operator's hands do not need to directly contact the parts on the production line, and the flow speed of the production line can be faster to improve production efficiency. Because the parts are actively attached to the sand net 2 under the action of the magnet 3, the grinding effect can meet the quality inspection requirements without the operator holding the parts with his hands, which greatly improves the safety of the operator in the grinding quality inspection process after the sheet metal processing is completed.
[0033] In one embodiment, Figure 1 and Figure 2 As shown, the magnet 3 includes a plurality of magnetic units 31 , and the plurality of magnetic units 31 are evenly distributed in the elastic body 1 .
[0034] In this embodiment, a plurality of magnetic units 31 are provided in the elastic body 1 , so that the magnetic attraction force in the elastic body 1 can be dispersed, so that the elastic body 1 can adsorb the parts when approaching the parts in all directions.
[0035] In one embodiment, Figure 1 and Figure 2 As shown, the elastic body 1 is in a cylindrical structure, and a plurality of magnetic units 31 are evenly distributed along the circumference of the elastic body 1 .
[0036] In this embodiment, the elastic body 1 is set as a cylinder, which can better evenly grind the surface of the part, and the multiple magnetic units 31 can be evenly distributed in the elastic body 1. Here, the multiple magnetic units 31 are preferably distributed in a circularly equidistant form. Of course, the multiple magnetic units 31 can also be evenly distributed in a rectangular array or other evenly distributed forms. The evenly distributed magnetic body can make the overall force of the part uniform when it is adsorbed against the sand net 2, so that the grinding is uniform, and it is also convenient to separate the grinding quality inspection tool from the part after the grinding is completed.
[0037] In one embodiment, Figure 1 and Figure 2 As shown, the elastic body 1 has a plurality of assembly grooves 15 evenly distributed along the circumference and opening upward, and the magnetic unit 31 is detachably embedded in the assembly groove 15 .
[0038] In this embodiment, the upper surface of the elastic body 1 is provided with a plurality of assembly grooves 15 opening upward, so that the magnetic unit 31 can be detachably embedded in the elastic body 1. In order to facilitate insertion and removal in the elastic body 1, the magnetic unit 31 is preferably a cylindrical structure. Of course, the magnetic unit 31 can also be other structures that are convenient for embedding and removal. In order to make the magnetic distribution more uniform, a plurality of assembly grooves 15 opening upward are evenly distributed on the elastic body 1 along the circumference, so that the distribution of the magnetic unit 31 is also evenly distributed along the circumference of the elastic body 1. The plurality of assembly grooves 15 can also be irregularly distributed. Of course, the case where only one assembly groove 15 is provided, or the case where the assembly groove 15 faces other directions, also falls within the protection scope of the utility model and will not be repeated here.
[0039] In one embodiment, the magnet 3 includes at least one annular magnetic unit 31 , and the magnetic unit 31 is parallel to the sand screen 2 .
[0040] In this embodiment, the magnetic unit 31 in the shape of a ring and parallel to the sand screen 2 can also provide a uniformly distributed magnetic field for the elastic body 1 to assist the grinding quality inspection tool in uniformly magnetically attracting parts. The cylindrical magnetic unit 31 is parallel to the sand screen 2, specifically, the upper and lower surfaces of the ring are parallel to the plane where the sand screen 2 is located. In order to achieve a uniform adsorption effect, the magnetic unit 31 can also be a disc-shaped structure, and the disc-shaped magnetic unit 31 completely covers a portion of the plane in the cylindrical elastic body 1. Correspondingly, the assembly groove 15 can be a groove structure that is annular or circular as a whole, and the magnetic unit 31 can be completely placed in the assembly groove 15.
[0041] In one embodiment, Figure 1 and Figure 2 As shown, the magnetic unit 31 is a permanent magnet, or the magnetic unit 31 is an electromagnet.
[0042] In this embodiment, when the magnetic unit 31 is a permanent magnet, the magnetic force of the magnetic unit 31 cannot be controlled, and the parts can only be actively adsorbed. After the grinding process is completed, the operator manually separates the parts from the sand screen 2. When the magnetic unit 31 is an electromagnet, each magnetic unit 31 needs to be powered on, and a corresponding magnetic switch button is set on the elastic body 1. The operator controls the magnetism of the magnet 3 through the magnetic switch, so that the sand screen 2 and the parts can be easily separated after the grinding is completed, so as to facilitate quality inspection.
[0043] In one embodiment, Figure 3 As shown, the elastic body 1 includes a fixing plate 11 , a sponge layer 12 and a pad 13 which are stacked in sequence from top to bottom, the sand net 2 is connected to the lower surface of the pad 13 , and the magnet 3 is connected to the lower surface of the fixing plate 11 .
[0044] In this embodiment, the main part with a larger volume in the elastic body 1 is the elastic sponge layer 12, and the fixing plate 11 is a hard plate body without elasticity. The fixing plate 11 is arranged above the sponge layer 12, which can maintain the overall shape of the elastic body 1 and facilitate the operator to exert force downward through the fixing plate 11 during grinding. The pad 13 is made of EVA plastic and can absorb impact from top to bottom. The pad 13 cooperates with the sponge layer 12 to make the force exerted by the operator act on the surface of the part in a unified direction, thereby improving the relative movement smoothness between the sand net 2 and the part, and then improving the grinding effect.
[0045] In one embodiment, Figure 1 As shown, a hand-held portion 14 is provided on the fixing plate 11. Further, the hand-held portion 14 includes an elastic band, and two ends of the elastic band are fixedly connected to the fixing plate 11 respectively.
[0046] In this embodiment, in order to facilitate the operator to hold the elastic body 1 and prevent the operator from slipping and causing the hand to be separated from the grinding quality inspection tool, a hand-held portion 14 is provided on the fixed plate 11 for the user to hold. Preferably, the hand-held portion 14 is provided as an elastic band structure, and the operator's hand passes through the elastic band and the fixed plate 11, and the hand holds the fixed plate 11 tightly, and the back of the hand is elastically tightened by the elastic band, thereby improving the operational stability of the grinding process.
[0047] In one embodiment, Figure 4 As shown, Velcro 21 is provided on two opposite sides of the sand net 2 , and the sand net 2 is detachably connected to the elastic body 1 through the Velcro 21 .
[0048] In this embodiment, Velcro 21 is respectively arranged on opposite sides of the sand net 2, and elastic fibers with hooks and barbs are specifically arranged on the Velcro 21. Correspondingly, soft fibers matching the elastic fibers with hooks and barbs on the elastic body 1 are also respectively arranged on opposite sides of the elastic body 1. The elastic fibers with hooks and barbs are detachably bonded to the soft fibers, so that the sand net 2 is connected to the elastic body 1 and the relative positions are fixed. Of course, the number of Velcro 21 can also be three, four, five, etc., and the connection between the sand net 2 and the elastic body 1 can also use other detachable connection structures, which will not be repeated here.
[0049] As needed, the above technical solutions can be combined to achieve the best technical effect.
[0050] The above are only the principles and preferred embodiments of the present invention. It should be noted that, for those skilled in the art, on the basis of the principles of the present invention, several other modifications can be made, which should also be considered as the protection scope of the present invention.
