Technical Field

[0001] The utility model relates to the technical field of grinding and polishing, in particular to a multi-axis self-adaptive grinding and polishing workstation. Background Art

[0002] Grinding and polishing refers to a processing method that uses mechanical, chemical or electrochemical effects to reduce the surface roughness of a workpiece to obtain a bright and smooth surface.

[0003] Most of the grinding and polishing processes are mechanical. After the processing of some complex curved parts, a large number of knife marks will remain on the surface. At present, most of them are polished manually. The parts are polished with manual sandpaper. This grinding method is not only inefficient, but also has poor consistency of finished products, and the appearance quality is also uneven.

[0004] In order to solve the above problems, at present, there are also a few industrial robots that use external force to control grinding tools, and cooperate with sensor detection to realize the grinding and polishing of parts. When using robots for grinding work, multiple devices are often required to cooperate to complete it. Therefore, many devices are integrated into a grinding and polishing workstation. Most of the existing grinding and polishing workstations require manual replacement of parts, that is, the parts to be polished are installed in the workstation, and after the grinding and polishing are completed, they are taken out, and then new parts to be polished are reinstalled in the workstation. Although this workstation has improved accuracy and efficiency, the process of replacing parts still wastes a lot of time, so that the grinding efficiency of the workstation is still low.

[0022] The preferred embodiments of the present invention are described below with reference to the accompanying drawings. It should be understood by those skilled in the art that these embodiments are only used to explain the technical principles of the present invention and are not intended to limit the protection scope of the present invention.

[0023] refer to Figure 1 , 2 The utility model proposes a multi-axis adaptive grinding and polishing workstation, including a box body 1, a material changing area is arranged on a corner of the front surface of the box body 1, the material changing area is located outside the box body 1, and the box body 1 is provided with a material changing port corresponding to the material changing area.

[0024] refer to Figure 3 A seven-degree-of-freedom robot arm 2, a grinding component 3, a polishing component 4 and a detection component are installed in the box 1, wherein the grinding component 3 adopts a purchased belt sander, which is directly installed at a designated position in the box 1. The parts are clamped to the grinding position of the belt sander by the robot arm 2 to complete the grinding process of the parts, that is, the belt sander can simultaneously meet the processes of rough polishing, medium polishing and fine polishing of the parts.

[0025] The polishing assembly 4 includes a polishing wheel 41 and a cleaning wheel 42. After the polishing assembly 3 is used to perform fine polishing on the part, the mechanical arm 2 clamps the part and places it on the polishing wheel 41. The polishing wheel 41 further polishes the part. The polishing wheel 41 uses a felt wheel or a cloth wheel. When in use, polishing wax is applied to the surface of the polishing wheel 41. After polishing, the surface of the part is cleaned with the cleaning wheel 42 to remove the abrasive and impurities on the surface of the workpiece to ensure the surface cleanliness of the workpiece before testing.

[0026] The detection component includes a contour sensor and a roughness sensor, which are installed in the box 1 without affecting the position of other processes. The two sensors are used to detect the contour and roughness of the parts. Because the two sensors are purchased parts, and the usage and process are also existing technologies, they will not be repeated here.

[0027] It also includes a feeding assembly 5, which is arranged through the box body 1, that is, the two ends of the feeding assembly 5 are respectively arranged inside and outside the box body 1, wherein the end of the feeding assembly 5 located outside is placed in the material replacement area. The feeding assembly 5 is connected to two feeding tables 51 that slide towards each other, and the two feeding tables 51 can simultaneously realize opposite movement, that is, one moves toward the inside of the box body 1, and the other moves toward the outside of the box body 1, and vice versa. The two feeding tables 51 are both hollow, and the size of one of them is larger than the other, so that the feeding table 51 of small size can pass through the inside of the feeding table 51 of large size.

[0028] refer to Figure 4 , 5 The feeding assembly 5 includes a feeding rack 52 , the two ends of which are respectively arranged inside and outside the box body 1 , and the two feeding platforms 51 are both slidably connected to the feeding rack 52 .

[0029] The feeding rack 52 includes two installation boxes 521, one of which is arranged inside the box body 1, and the other is arranged outside the box body 1; two guide columns 522 are also arranged corresponding to each feeding table 51, and the two ends of the guide columns 522 are respectively fixedly connected to the two installation boxes 521, and the feeding table 51 is slidably connected to the corresponding two guide columns 522 through a slider to achieve the purpose of sliding along the direction of the guide columns 522.

[0030] A lead screw 523 is also provided corresponding to each feeding platform 51. The two lead screws 523 are arranged parallel to the guide column 522. The two ends of the lead screw 523 are rotatably connected to the two mounting boxes 521 respectively. The two lead screws 523 are arranged up and down, and the large-sized feeding platform 51 is threadedly connected to the lead screw 523 located below through a slider, and the lead screw 523 located above is passed through the large-sized feeding platform 51, and the small-sized feeding platform 51 is threadedly connected to the lead screw 523 located above through a slider.

[0031] One end of the lead screw 523 located above is also connected to a driving device 53 through a coupling. The driving device 53 is a motor. The driving device 53 is arranged outside the box body 1, and the driving device 53 is installed on the installation box 521. The driving device 53 can drive the lead screw 523 to rotate, and then the rotation of the lead screw 523 can drive the feeding table 51 to slide along its length direction. The sliding direction of the feeding table 51 can be further controlled by the forward and reverse rotation of the lead screw 523.

[0032] refer to Figure 6 , the two lead screws 523 are connected by two gears 5211, the two gears 5211 are coaxially mounted on the two lead screws 523, and the two gears 5211 mesh with each other. When the driving device 53 drives one of the lead screws 523 to rotate, the other lead screw 523 can also be driven to rotate through the transmission of the gear 5211, and the rotation directions of the two lead screws 523 are opposite. It should be noted that both lead screws 523 are provided with positive threads. When the two lead screws 523 rotate at the same time and in opposite directions, the two feeding tables 51 can slide toward each other at the same time. The two gears 5211 are mounted in the mounting box 521 located outside the box body 1.

[0033] refer to Figure 7 A chip receiving groove 6 is installed below the grinding component 3 and the polishing component 4, so that the debris generated during grinding and polishing can fall into the chip receiving groove 6 for centralized collection and treatment. A weak magnetic plate 61 is installed on the bottom wall of the chip receiving groove 6, and the weak magnetic plate 61 is connected to the chip receiving groove 6 by gluing. The weak magnetic plate 61 can generate a weak magnetic field, further generating a certain magnetic force on the debris, so that the debris can be adsorbed in the chip receiving groove 6, avoiding the problem of dust in the box body 1 due to its small size and easy floating in the box body 1.

[0034] In summary, the utility model can achieve the purpose of the two feeding tables 51 alternately entering and exiting the box 1 by setting two relatively sliding feeding tables 51. Further, in the process of sliding toward each other, it can realize the purpose of feeding the parts to be polished into the box 1 and sending the polished parts out of the box 1. At the same time, during the process of polishing in the box 1, the operator can also synchronously remove the sent parts from the feeding table 51 and place new parts to be polished, and wait for the next time to send out the parts and then feed the parts to be polished, which greatly shortens the speed of replacing parts and improves production efficiency. By setting a weak magnetic plate 61 in the chip receiving groove 6, the effect of weak magnetic adsorption of metal debris during polishing can be achieved, and the debris generated during grinding and polishing can be further prevented from floating to other mechanisms and affecting the operation of the mechanism.
