具体实施方式Detailed ways
下面将结合本实用新型实施例中的附图，对本实用新型实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本实用新型一部分实施例，而不是全部的实施例。基于本实用新型中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，均属于本实用新型保护的范围。The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. example. Based on the embodiments of the present utility model, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of the present utility model.
研磨机的主要类型有圆盘式研磨机、转轴式研磨机和各种专用研磨机。圆盘式研磨机分单盘和双盘两种，以双盘研磨机应用最为普通。在双盘研磨机上，多个工件同时放入位于上、下研磨盘之间的保持架内，保持架和工件由偏心或行星机构带动作平面平行运动。下研磨盘旋转，与之平行的上研磨盘可以不转，或与下研磨盘反向旋转，并可上下移动以压紧工件(压力可调)。此外，上研磨盘还可随摇臂绕立柱转动一角度，以便装卸工件。双盘研磨机主要用于加工两平行面、一个平面(需增加压紧工件的附件)、外圆柱面和球面(采用带V形槽的研磨盘)等。加工外圆柱面时,因工件既要滑动又要滚动，须合理选择保持架孔槽型式和排列角度。单盘研磨机只有一个下研磨盘，用于研磨工件的下平面，可使形状和尺寸各异的工件同盘加工，研磨精度较高。有些研磨机还带有能在研磨过程中自动校正研磨盘的机构。The main types of grinders are disc grinders, shaft grinders and various special grinders. There are two types of disc grinders: single disc and double disc, and the double disc grinder is the most common. On the double-disc grinding machine, multiple workpieces are placed in the cage between the upper and lower grinding discs at the same time, and the cage and workpieces are driven by the eccentric or planetary mechanism to move in parallel. The lower grinding disc rotates, and the upper grinding disc parallel to it can not rotate, or rotate in the opposite direction with the lower grinding disc, and can move up and down to press the workpiece (adjustable pressure). In addition, the upper grinding disc can also rotate an angle around the column with the rocker arm to facilitate loading and unloading of workpieces. The double-disc grinder is mainly used to process two parallel surfaces, one plane (need to add accessories for pressing the workpiece), outer cylindrical surface and spherical surface (use grinding disc with V-shaped groove), etc. When machining the outer cylindrical surface, because the workpiece has to slide and roll, it is necessary to choose the cage hole type and arrangement angle reasonably. The single-disc grinder has only one lower grinding disc, which is used to grind the lower plane of the workpiece, so that workpieces with different shapes and sizes can be processed on the same disc, and the grinding accuracy is high. Some grinders also have a mechanism that automatically corrects the grinding disc during the grinding process.
研磨方法一般可分为湿研、干研和半干研3类。(1)湿研：又称敷砂研磨，把液态研磨剂连续加注或涂敷在研磨表面，磨料在工件与研具间不断滑动和滚动，形成切削运动。湿研一般用于粗研磨。(2)干研：又称嵌砂研磨，把磨料均匀在压嵌在研具表面层中，研磨时只须在研具表面涂以少量的硬脂酸混合脂等辅助材料。干研常用于精研磨。(3) 半干研：类似湿研，所用研磨剂是糊状研磨膏。研磨既可用手工操作，也可在研磨机上进行。工件在研磨前须先用其他加工方法获得较高的预加工精度，所留研磨余量一般为5～30微米。Grinding methods can generally be divided into three categories: wet grinding, dry grinding and semi-dry grinding. (1) Wet grinding: also known as sand-coated grinding, the liquid abrasive is continuously injected or coated on the grinding surface, and the abrasive continuously slides and rolls between the workpiece and the grinding tool to form a cutting motion. Wet grinding is generally used for coarse grinding. (2) Dry grinding: also known as sand-embedded grinding, the abrasive is evenly pressed and embedded in the surface layer of the grinding tool. When grinding, only a small amount of stearic acid mixed fat and other auxiliary materials need to be coated on the surface of the grinding tool. Dry grinding is often used for fine grinding. (3) Semi-dry grinding: similar to wet grinding, the abrasive used is paste grinding paste. Grinding can be done by hand or on a grinder. Before the workpiece is ground, other processing methods must be used to obtain higher pre-processing accuracy, and the remaining grinding allowance is generally 5 to 30 microns.

In other embodiments, the position of the opening 21 can also deviate from the center position, but it needs to be satisfied that the opening 21 is located between the three weight devices 3, and the diameter of the opening 21 can be selected according to the actual situation. This is not limited. Due to the existence of the opening, it can avoid the grinding marks on the four corners of the product caused by the protrusion in the middle of the grinding disc when the grinding time is too long.
本实施方式中，研磨盘2在动力装置驱动下绕研磨盘的中心旋转， 3个压重装置3相对于地面固定，与研磨盘2产生相对运动。产品4位于压重装置3与研磨盘2之间，压重装置3与研磨盘2相对运动时即可对产品进行研磨加工。在另一个实施方式中，至少两个压重装置绕研磨盘的中心旋转，且运行速度小于研磨盘的运行速度，与研磨盘产生相对运动。在又一个实施方式中，至少两个压重装置绕研磨盘的中心旋转，且运行方向与研磨盘的运行方向相反，与研磨盘产生相对运动。本实用新型对此均不作限定，只需保证压重装置与研磨盘相对运动。In this embodiment, the grinding disc 2 rotates around the center of the grinding disc under the drive of the power device, and the three weight devices 3 are fixed relative to the ground and move relative to the grinding disc 2 . The product 4 is located between the weight device 3 and the grinding disc 2, and the product can be ground when the weight device 3 and the grinding disc 2 move relative to each other. In another embodiment, at least two weight devices rotate around the center of the grinding disc, and the running speed is lower than the running speed of the grinding disc, so as to generate relative motion with the grinding disc. In yet another embodiment, at least two weight devices rotate around the center of the grinding disc, and the running direction is opposite to the running direction of the grinding disc, so as to generate relative motion with the grinding disc. The utility model is not limited to this, it only needs to ensure the relative movement of the weight device and the grinding disc.

The structures of the three ballast devices in this embodiment are the same, and the other two ballast devices will not be repeated here. The supporting part restricts the movement of the product in the horizontal direction, the main body of the weight restricts the movement of the product in the vertical direction, and the supporting part and the main body of the weight jointly restrict the movement of the product. Since the movement of the product in the horizontal direction and the vertical direction is restricted, it can effectively avoid the wear marks on the corners of the product during the grinding process.
本实施方式中，研磨台1的上表面还设置有洒水口(图中未示出)，压重装置3与研磨盘2之间设置有研磨垫(图中未示出)。现有技术中，研磨垫处于干磨状态，研磨垫会变硬，易损，形成凹坑。本实用新型中，洒水口在研磨产品的过程中，向研磨垫上洒水，使研磨垫有浮力，研磨垫表面不再有凹坑，较为平整，且研磨垫的耐用性大大提高。另外，由于是用水磨，研磨后的水可以直接排放，不会污染环境。In this embodiment, the upper surface of the grinding table 1 is further provided with a sprinkler (not shown in the figure), and a grinding pad (not shown in the figure) is provided between the weight device 3 and the grinding disc 2 .
