背景技术Background technique
抛光技术，又称镜面加工，是为了得到光亮表面而采用的加工工艺，其加工特点，是加工基本不改变工件形状，旨在提高表面粗糙度。抛光不仅增加工件的美观，而且能够改善材料表面的耐腐蚀性、耐磨性及其他特殊性能。在生活、生产中的各个领域都有广泛应用。抛光既可作为零件的最终工序，也可作为镀膜前的表面预处理工序。Polishing technology, also known as mirror processing, is a processing technology used in order to obtain a bright surface. Its processing feature is that the processing basically does not change the shape of the workpiece and aims to improve the surface roughness. Polishing not only increases the beauty of the workpiece, but also improves the corrosion resistance, wear resistance and other special properties of the material surface. It is widely used in various fields of life and production. Polishing can be used as the final process of the part, as well as the surface pretreatment process before coating.
传统的抛光设备，在传统的制造过程中，为了满足设备的升降精度需求和平面度的需求，常规的抛光机器的升降装置中用于固定升降电机、行程导轨或者丝杆的连接板（底板、固定座等）固定板大都采用整体加工，整板的加工，虽然升降精度和平面度得到了满足，但是加工成本较高，而且装配人员在安装连接板时需要浪费大量的劳动力，由于连接板是一个大的整体，然后重量很重，装配人员在安装时比较困难。Traditional polishing equipment, in the traditional manufacturing process, in order to meet the requirements of the lifting accuracy and flatness of the equipment, the lifting device of the conventional polishing machine is used to fix the lifting motor, the travel guide or the connecting plate (bottom plate, Fixing seats, etc.) The fixing plates are mostly processed as a whole. Although the lifting accuracy and flatness of the whole plate are satisfied, the processing cost is high, and the assembly personnel need to waste a lot of labor when installing the connecting plate. A large whole, and then the weight is very heavy, it is difficult for the assembler to install it.

In addition, the terms "first", "second", and "third" are only used for descriptive purposes, and cannot be understood as indicating or implying relative importance.
如图1至图12所示，一种内部曲面抛光机器，包括矩形基座1、升降装置3、弧面分度装置5和万向调节杆508等几部分。As shown in Figures 1 to 12, an internal curved surface polishing machine includes a rectangular base 1, a lifting device 3, a curved surface indexing device 5, and a universal adjustment rod 508.
如图1所示，矩形基座1，包括矩形基座1本体、工作台面101、上框架2和控制箱14；矩形基座1本体安置在地面上，工作台面101设置在所述矩形基座1本体的上面，上框架2安装在所述矩形基座1本体上面，控制箱14设置在所述矩形基座1本体的内部。为了合理的利用的矩形基座1的空间，矩形基座1为中空结构的设计，而且中空结构设计的矩形基座1具有收纳的价值，能够将控制柜收纳其中，不用单独的再单独的做一个控制柜，合理的利用了矩形基座1的空间，有节省了单独做控制箱14的费用。As shown in Figure 1, the rectangular base 1 includes a rectangular base 1 body, a work surface 101, an upper frame 2 and a control box 14. The rectangular base 1 body is placed on the ground, and the work surface 101 is set on the rectangular base. 1. On the top of the body, the upper frame 2 is installed on the body of the rectangular base 1, and the control box 14 is arranged inside the body of the rectangular base 1. In order to make reasonable use of the space of the rectangular base 1, the rectangular base 1 is designed with a hollow structure, and the rectangular base 1 designed with the hollow structure has the value of storage, and the control cabinet can be stored in it instead of a separate one. A control cabinet makes reasonable use of the space of the rectangular base 1 and saves the cost of making the control box 14 separately.
在进一步实例中，上框架2呈矩形框架结构，为了方便装配人员将上框架2装配安装到矩形基座1本体的上面，上框架2包括，垫板201、防护件4和方管202；垫板201螺纹设置在所述矩形基座1本体的上面，且位于矩形结构长度方向，方管202安装在所述垫板201上面，防护件4设置在方管202上面，并且防护件4的两端同时分别连接在方管202上面。在安装上框架2前，装配人员现将多个方管202剪裁至设定尺寸，然后将每个方管202拼焊成一个矩形结构的框架，众所周知，如果将拼焊好的矩形框架直接拼焊安装在矩形基座1本体上面，在拼焊时，需要借助外力或者工装才能将由方管202拼焊成矩形框架，安装到矩形基座1本体上面，一旦拼焊完成，后面想要拆卸，非常困难。为了解决拆卸困难的问题，同时不借助外力和工装也可以完成装配工装，在方管202拼焊成的矩形结构的长度方向设置了垫板201，并且在垫板201的上面设置至少四个螺纹孔，通过螺栓将上框架2螺接在矩形基座1上面。In a further example, the upper frame 2 has a rectangular frame structure. In order to facilitate the assembly personnel to assemble and install the upper frame 2 on the body of the rectangular base 1, the upper frame 2 includes a backing plate 201, a protective member 4 and a square tube 202; The plate 201 is threadedly arranged on the body of the rectangular base 1 and located in the length direction of the rectangular structure. The square tube 202 is installed on the backing plate 201, the guard 4 is arranged on the square tube 202, and two of the guard 4 The ends are respectively connected to the square tube 202 at the same time. Before installing the upper frame 2, the assembler now cuts a number of square tubes 202 to a set size, and then welds each square tube 202 into a rectangular structure frame. As we all know, if the tailor-welded rectangular frame is directly assembled Welding is installed on the body of the rectangular base 1. During tailor welding, external force or tooling is needed to weld the square tube 202 into a rectangular frame and install it on the body of the rectangular base 1. Once the tailor welding is completed, it will be removed later. very difficult. In order to solve the problem of difficult disassembly, and at the same time, the assembly tooling can be completed without the help of external force and tooling. A backing plate 201 is provided in the length direction of the rectangular structure welded by the square tube 202, and at least four threads are provided on the backing plate 201 Hole, the upper frame 2 is screwed on the rectangular base 1 through bolts.
在进一步实例中，如果在上框架2的方管202上面直接打孔攻丝，也可以满足安装简单，拆卸方便的需求，但是方管202上面打孔，方管202的承载力大大下降，而且由于选用的方管202的是一个空心的结构无缝矩形方管202，在方管202上打孔攻丝，其有效的螺纹较少，在设备工作时，可能会产生振动，或者搬运时产生的振动，振动容易产生将方管202上面的螺纹产生滑丝，从而使得螺纹失效。容易造成机器在工作时，带动上框架2晃动的现象的发生，因此在垫板201固定在方管202上，并在垫板201上面打孔攻丝，为最优方案。同时为了方便观测机器工作的实时状态，也为了发生危险情况时增加操作人员的安全性能，在由方管202拼焊成的矩形框架上面安装了防护件4，为了监测的便利性和透明性、同时也为了安全性，防止在发生危险时防护件4四溅，给操作员造成危险，防护件4采用透明性和透光性较好的亚克力板，选用亚克力板作为防护件4，其亚克力板的抗冲击能力较强，和同等透光性和透明性较好的玻璃相比而言，亚克力板的抗冲击性能是玻璃的16倍，即使发生冲击，其压力板不会想玻璃一样四溅。In a further example, if the square tube 202 of the upper frame 2 is directly punched and tapped, it can also meet the requirements of simple installation and convenient disassembly. However, if the square tube 202 is punched, the bearing capacity of the square tube 202 is greatly reduced, and Since the selected square tube 202 is a hollow structure seamless rectangular square tube 202, the square tube 202 is punched and tapped, and its effective threads are less. When the equipment is working, it may produce vibration or produce The vibration is prone to cause the thread on the square tube 202 to slip, thereby causing the thread to fail. It is easy to cause the phenomenon of shaking the upper frame 2 when the machine is working. Therefore, fixing the backing plate 201 on the square tube 202 and punching and tapping on the backing plate 201 is the optimal solution. At the same time, in order to facilitate the observation of the real-time status of the machine, and to increase the safety of the operator in the event of a dangerous situation, a protective piece 4 is installed on the rectangular frame formed by the square tube 202 tailored welding. For the convenience and transparency of monitoring, At the same time, for the sake of safety, to prevent the protective part 4 from splashing and causing danger to the operator when danger occurs, the protective part 4 adopts an acrylic plate with good transparency and light transmission, and an acrylic plate is selected as the protective part 4. Its acrylic plate Compared with glass with the same light transmittance and better transparency, the impact resistance of acrylic plate is 16 times that of glass. Even if an impact occurs, the pressure plate will not splash like glass. .

Because the eccentric cam 503 is designed as an eccentric structure, and the eccentric cam 503 is divided into a big wheel 10 and a small wheel 11. A locking hole 12 is provided on the side of 11, and one end of the small wheel 11 is connected with the rotating end of the speed regulating motor 502. In order to prevent the rotation of the speed regulating motor 502 from causing the eccentric cam 503 to loosen, the designed locking The hole 12 further locks the eccentric cam 503. As the boss of the long plate 506 and the eccentric cam 503 are axially parallel to each other during movement, the speed-regulating motor 502 rotates once. Due to the eccentric design of the eccentric cam 503, when the eccentric cam 503 is running Rotate an elliptical track to the maximum radius of the eccentric cam 503. The eccentric cam 503 conflicts with the cam of the long plate 506, and the parts connected to the long plate 506 travel an elliptical track.

During the working process, the force sensor installed in the lower block 507 senses the pressure of polishing, and passes this pressure signal through A/ The D converter converts to a discrete signal.
