Description

Technical Field

[0001] The utility model relates to the field of automation equipment, in particular to a flexible polishing component. Background Art

[0002] After the production of melamine tableware, there will be burrs on the edges. In order to avoid the problem of wasting time in subsequent use, the burrs need to be removed. At this time, they are generally ground off by a grinding wheel. In the existing technology, the grinding wheel is generally fixed. During the grinding process, the burrs are ground off by moving the tableware. Since the tableware is generally round or has an arc surface on the outside, the tableware needs to be rotated continuously during the grinding process. At the same time, due to the different sizes of the burrs, the distance between the tableware and the grinding wheel needs to be adjusted continuously during the grinding process to completely grind off the burrs. However, since the grinding wheel is fixed, the position spacing between the tableware and the grinding wheel is now manually adjusted to control the grinding amount. This is less efficient in the production process and is prone to excessive grinding, thereby affecting product quality. Utility Model Content

[0017] To make the above-mentioned objects, features, and advantages of the present invention more clearly understood, the following detailed description of specific embodiments of the present invention is provided in conjunction with the accompanying drawings. The following description sets forth many specific details to facilitate a full understanding of the present invention. However, the present invention can be implemented in many other ways than those described herein, and those skilled in the art may make similar modifications without departing from the scope of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0018] It should be noted that when an element is referred to as being "fixed to" another element, it may be directly on the other element or there may be an intermediate element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be an intermediate element at the same time. In contrast, when an element is referred to as being "directly on" another element, there is no intermediate element. The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only."

[0019] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the art to which this invention pertains. The terms used herein in the specification of this invention are intended only to describe specific embodiments and are not intended to limit this invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0020] like Figures 1 to 3 As shown, a flexible grinding assembly is characterized in that it includes a fixed plate 1, the upper side of the fixed plate 1 is connected to a mounting plate 2 through a guide rail slider structure, the two ends of the guide rail in the guide rail slider are respectively fixed with a first limit shaft 3 and a second limit shaft 4, the mounting plate 2 is installed with a grinding motor 5, the machine shaft of the grinding motor 5 is connected to a grinding wheel 6, and an elastic reset mechanism is provided between the mounting plate 2 and the fixed plate 1, which is used to make the slider in the guide rail slider abut against the first limit shaft 3.

[0021] An elastic reset mechanism is provided between the mounting plate 2 and the fixed plate 1, so that the positions of the mounting plate 2 and the grinding wheel 6 are not fixed and will move under the action of external force. During use, it is only necessary to rotate the workpiece so that the grinding wheel 6 can move along with the unevenness of the workpiece surface to adjust its position, thereby improving the grinding efficiency and grinding quality.

[0022] At the same time, under the action of the elastic reset mechanism, the grinding wheel 6 will exert a certain force on the workpiece, thereby ensuring the grinding effect between the grinding wheel 6 and the workpiece, and avoiding the situation where the workpiece and the grinding wheel 6 are only in contact, which affects the grinding.

[0023] The elastic reset mechanism makes the slider abut against the first limit shaft 3. At this time, the elastic reset mechanism includes a guide rod arranged parallel to the guide rail, and a first limit plate and a second limit plate are provided at both ends of the guide rod. The lower side of the mounting plate 2 is provided with a limit ring sleeved on the outside of the guide rod, and a spring is provided between the second limit plate and the limit ring. The elastic reset mechanism is arranged between the fixed plate 1 and the mounting plate 2. At this time, the two ends of the guide rod are fixed to the fixed plate 1 by the first limit plate and the second limit plate respectively. A limit ring is provided on the lower side of the mounting plate 2. The limit ring is sleeved on the outer side of the guide rod, and the spring is sleeved on the outer side of the guide rod and is located between the second limit plate and the limit ring. The elastic member is in a compressed state, so that the limit ring abuts against the first limit plate, and the mounting plate 2 is connected to the fixed plate 1 through the guide rail slider. In this way, the mounting plate 2 can slide relative to the fixed plate 1. Under the action of the spring, the mounting plate 2 is in a position close to the first limit plate. During the use of the grinding wheel 6, the workpiece at the position close to the side of the first limit plate contacts the grinding wheel 6, thereby grinding the product. At this time, since the grinding wheel 6 contacts the workpiece, the grinding The grinding wheel 6 will receive a force toward the second limit plate, thereby causing the mounting plate 2 to move toward the second limit plate, thereby compressing the spring. After compression, the spring can give the limit ring a force toward the first limit plate, causing the limit ring, the mounting plate 2, and the grinding wheel 6 to move toward the first limit plate, thereby ensuring that a clamping force is formed between the grinding wheel 6 and the workpiece. The grinding wheel 6 is pressed against the outside of the workpiece to ensure normal grinding. In the process of rotating the workpiece, if the burr suddenly becomes larger or the size of the workpiece becomes larger, the force acting between the workpiece and the grinding wheel 6 becomes larger, which can compress the spring, thereby increasing the distance between the grinding wheel 6 and the workpiece to avoid excessive grinding. If the burr suddenly becomes larger, it is necessary to move the workpiece or increase the grinding time to remove the burr from the workpiece.

[0024] At this time, the grinding wheel 6 can be adjusted to follow the surface of the workpiece to improve the grinding efficiency and quality.

[0025] At this time, the guide rod and the corresponding spring are used to provide elastic force. In order to ensure the overall stability of the force applied to the mounting plate 2, in this embodiment, two guide rods are provided, which are located on both sides of the guide rail, and two corresponding limit rings and springs are also provided. In this way, during the movement of the mounting plate 2, the mounting plate 2 and the fixed plate 1 are relatively stable.

[0026] During the grinding process, if the workpiece is large, it is necessary to grind the product horizontally to improve the grinding efficiency. Therefore, a horizontal displacement between the workpiece and the grinding wheel 6 is required. In this embodiment, the flexible grinding assembly further includes a horizontal adjustment structure 7. The fixed plate 1 is fixed to the movable plate position of the horizontal adjustment structure 7. Under the action of the horizontal adjustment structure 7, the fixed plate 1 moves horizontally. At this time, under the action of the horizontal adjustment structure 7, the fixed plate 1 moves horizontally, and then the mounting plate 2 and the grinding wheel 6 also move horizontally. In this way, a large area can be polished by simply rotating the workpiece.

[0027] Specifically, the lateral adjustment structure 7 includes a base plate 71, a motor 72 is fixed to one end of the base plate 71, the shaft of the motor 72 is connected to a screw 73 through a coupling, a screw nut seat 74 is provided on the outside of the screw 73, a horizontal movable plate 75 is fixed to the screw nut seat 74, a vertical movable plate 76 is provided on the upper side of the horizontal movable plate 75, the fixed plate 1 and the vertical movable plate 76 are fixed, and further, the screw nut seat 74 of the base plate 71 is arranged on the upper side of the base plate 71 through a guide rail slider structure. Under the action of the motor 72, the screw nut seat 74 moves laterally, and then the horizontal fixed plate 1 and the vertical movable plate 76 both move laterally, thereby controlling the lateral movement of the fixed plate 1 and the corresponding mounting plate 2 and the grinding motor 5, and then controlling the lateral reciprocating movement of the grinding wheel 6 for grinding.

[0028] Finally, in order to make the grinding wheel 6 in an inclined state, in this embodiment, the fixed plate 1 is tilted, and one end of the first limit axis 3 of the mounting plate 2 is higher than one end of the second limit axis 4. Specifically, the bottom or top of the vertical movable plate 76 is provided with an inclined edge. After the fixed plate 1 and the vertical movable plate 76 are fixed, the fixed plate 1 is in an inclined state. At this time, the top or bottom of the vertical movable plate 76 is set as an inclined edge. After the fixed plate 1 and the vertical movable plate 76 are fixed, the fixed plate 1 can be placed in an inclined state. At this time, the fixed plate 1 is tilted toward the side of the second limit plate, and the second limit plate side of the fixed plate 1 is lower than the second limit plate side. In this way, the mounting plate 2 and the grinding wheel 6 are both tilted toward the side of the second limit plate. In this way, under the action of gravity, the mounting plate 2 is on the side of the second limit plate. When grinding, the workpiece slightly pushes the grinding wheel 6 back a distance, and the grinding wheel 6 will exert a certain pressure on the workpiece to grind, thereby improving the grinding effect.

[0029] The technical features of the above-mentioned embodiments can be combined arbitrarily. In order to make the description concise, not all possible combinations of the technical features in the above-mentioned embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0030] The above-described embodiments merely represent several implementations of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that a person skilled in the art would be able to make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements fall within the scope of protection of the present invention. Therefore, the scope of protection of the present utility model patent shall be determined by the appended claims.
