The preferred embodiments in the following description are only examples, and those skilled in the art can think of other obvious variations. The basic principles defined in the following description of the present invention can be applied to other implementation schemes, variation schemes, improvement schemes, equivalent schemes, and other technical schemes that do not deviate from the spirit and scope of the present invention.

[0039] Those skilled in the art should understand that in the disclosure of the specification, the orientation or positional relationships indicated by the terms "longitudinal", "lateral", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc. are based on the orientation or positional relationships shown in the drawings. It is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, the above - mentioned terms should not be construed as limitations on the present invention.

[0040] It can be understood that the term "a" should be understood as "at least one" or "one or more". That is, in one embodiment, the number of an element can be one, while in other embodiments, the number of this element can be multiple. The term "a" should not be construed as a limitation on the number.

[0041] Reference Figures 1 to 11 , a prism surface grinding and polishing integrated machine according to a preferred embodiment of the present invention will be described in detail below. The prism surface grinding and polishing integrated machine includes a frame 100 and an operation box 200 disposed on the frame 100. The operation of each electrical component is controlled by the operation box 200. Two moving mechanisms 300 and a driving assembly are disposed in the upper part of the frame 100. The two moving mechanisms 300 are connected to the driving assembly in a manner that can be driven to move in the front-back direction α, the left-right direction β, and the up-down direction γ. A pneumatic chuck 500 for mounting a product 400 is disposed at the bottom of the moving mechanism 300. Generally, the product 400 is coaxially mounted at the bottom of the pneumatic chuck 500. The left-right direction β is the direction in which the two moving mechanisms 300 are arranged side by side. In the left-right direction β and the front-back direction α, the driving assembly drives the two moving mechanisms to move synchronously. In the up-down direction γ, the driving assembly drives the two moving mechanisms 300 to move up and down synchronously or non-synchronously. When moving up and down synchronously, it can drive two products 400 to move simultaneously, and thus process two products 400 simultaneously. When moving non-synchronously, the processing of the product 400 is controlled separately;

[0042] A liquid basin 600 for containing grinding liquid is disposed below the moving mechanism 300 on the frame 100, and three grinding discs 700 are correspondingly disposed at the bottom of the liquid basin 600 along the left-right direction β. The grinding disc 700 near the middle position is a fine grinding and polishing disc, and the grinding discs 700 near both sides are rough grinding and polishing discs, so that the driving assembly can drive the two moving mechanisms 300 to drive the corresponding products 400 to perform corresponding rough grinding and fine grinding, or fine grinding and rough grinding synchronously on the grinding discs 700.

[0043] For example, after the left product 400 is roughly ground by the leftmost rough grinding disc, it moves to the right to the finishing disc in the middle position for finishing. When the left product 400 moves to the finishing disc, a product 400 to be processed is installed on the pneumatic chuck 500 near the rightmost rough grinding disc. At this time, the finishing disc in the middle position and the rightmost rough grinding disc simultaneously perform finishing and rough grinding on the left product 400 and the right product 400. After the processing is completed, the product 400 after finishing in the middle position can be removed. Then, the moving mechanism 300 moves to the left as a whole. The product 400 after rough grinding on the rightmost side moves to the finishing disc in the middle position, and the pneumatic chuck 500 of the removed product 400 moves to the leftmost rough grinding disc. At this time, a product 400 to be processed is installed on the leftmost pneumatic chuck 500, and then the left product 400 and the right product 400 are simultaneously subjected to rough grinding and finishing by the leftmost rough grinding disc and the finishing disc in the middle position. Thus, two products 400 can be processed simultaneously in each round of processing, and the processing process flow remains unchanged. Furthermore, on the premise of ensuring the quality of the product 400, the processing efficiency can be effectively improved.

[0044] In one embodiment, three grinding fluid barrels 800 are provided at the rear side of the frame 100. The grinding fluid barrels 800 are respectively connected to the three liquid storage areas 601 of the liquid basin 600 through pipelines to supply grinding fluid to the three grinding discs 700 respectively.

[0045] Meanwhile, in combination with Figure 5 and Figure 6 , a grinding fixing seat 610 is provided on the bottom wall of the liquid basin 600, and a liquid retaining ring 620 is provided at the bottom of the liquid basin 600 near the outer ring of the grinding fixing seat 610 to prevent the grinding fluid from seeping into the grinding fixing seat 610 and affecting the normal operation of each component. A grinding shaft 630 is provided in the grinding fixing seat 610, and one end of the grinding shaft 630 located in the liquid basin 600 is coaxially connected to the grinding disc 700. One end of the grinding shaft 630 located below the liquid basin 600 is coaxially connected to a grinding motor 640. Thus, under the control of the operation box 200, the grinding disc 700 is driven to rotate by the grinding motor 640. Generally, the rotation speeds of the two rough grinding discs on both sides are the same, while the rotation speed of the finishing disc in the middle position is slightly larger. In addition, there may be differences in the grinding fluids used for the finishing disc and the rough grinding discs. Moreover, the teeth on the finishing disc are finer than those on the rough grinding discs.

[0046] In one embodiment, in combination with Figures 1 to 4, the driving assembly includes a left - right moving mechanism 10, a front - rear moving mechanism 20 and an up - down moving mechanism 30. Among them, the left - right moving mechanism 10 includes a left - right guide rail 11, a first motor 12, a first lead screw and a first lead screw nut 13. The left - right guide rail 11 and the first motor 12 both extend along the left - right direction β and are both directly or indirectly fixedly arranged on the top of the frame 100. The first motor 12 is coaxially connected to the first lead screw located in the left - right guide rail 11 at one end of the left - right guide rail 11 and drives the first lead screw to rotate directionally. Obviously, the extending direction of the first lead screw is the same as that of the left - right guide rail 11. In addition, the first lead screw nut 13 is threadedly fitted on the first lead screw in a manner that can move directionally along the left - right direction β. Thus, when the first lead screw is driven to rotate, the first lead screw nut 13 can move in a directional straight line;

[0047] The front - rear moving mechanism 20 includes a front - rear moving seat 21, a second motor 22, a second lead screw and a second lead screw nut. The front - rear moving seat 21 is fixedly connected to the top of the first lead screw nut 13 at the same time so as to be able to move directionally in a straight line along with the first lead screw nut 13. Since the front - rear moving seat 21 has a large span in the left - right direction β, a plurality of the first lead screw nuts 13 can be evenly arranged in the left - right direction β, so that the plurality of the first lead screw nuts 13 can drive the front - rear moving seat 21 to move synchronously, which can effectively ensure the stability of the movement of the front - rear moving seat 21. In addition, a front - rear guide rail 23 extending along the front - rear direction α is arranged on the top of the front - rear moving seat 21, and the second motor 22 is coaxially connected to the second lead screw located in the front - rear guide rail 23 at one end of the front - rear guide rail 23. The second lead screw nut is threadedly fitted on the second lead screw in a manner that can move directionally along the front - rear direction α. Furthermore, the directional rotation of the second motor 22 can be converted into the constant - speed linear movement of the second lead screw nut through the cooperation of the second lead screw and the second lead screw nut;

[0048] The vertical movement mechanism 30 includes two vertical movement seats 31, third motors 32 respectively arranged at the tops of the vertical movement seats 31, third lead screws 33 coaxially connected to the third motors 32 within the vertical movement seats 31, and third lead screw nuts 34 sleeved on the third lead screws 33. Among them, the two vertical movement seats 31 are arranged side by side along the left-right direction β and fixed at the top of the second lead screw nut, so as to be able to move linearly in a fixed direction along with the second lead screw nut. Among them, the two movement mechanisms 300 are respectively fixedly arranged on the two third lead screw nuts 34, and the two vertical movement seats 31 are respectively provided with upper and lower guide rails 35 for the two movement mechanisms 300 to move vertically in a fixed direction. Furthermore, under the control of the operation box 200, the two third motors 32 can rotate synchronously or asynchronously, so as to control the timing and moving speed of the corresponding product 400 moving up and down.

[0049] Generally, the two third motors 32 are controlled by the operation box 200 to rotate synchronously, so as to process two products 400 synchronously to ensure the processing efficiency. Only in some special cases, such as when a single product 400 needs to be processed separately, one of the third motors 32 will drive the corresponding product 400 to move up and down.

[0050] Further preferably, bellows covers 14, or flexible bellows machine tool guide rail protective covers, are respectively sleeved on the left-right guide rails 11, the front-back guide rails 23 and the upper-lower guide rails 35 for protecting the machine tool guide rails;

[0051] Drag chains 15 for placing wire materials are arranged on the sides of the left-right guide rails 11, the front-back guide rails 23 and the upper-lower guide rails 35.

[0052] Further preferably, in combination with Figure 7 and Figure 8, the moving mechanism 300 includes a fixing plate 41, two floating fixing seats 42, two floating arms 43, a fixing mechanism 44 and a floating mechanism. The fixing plate 41 is matched with the up-and-down guide rail 35 and fixedly connected to the third lead screw nut 34, and thus can move up and down directionally with the third lead screw nut 34. Two of the floating fixing seats 42 extend along the up-and-down direction γ and are fixedly arranged side by side on the surface of the fixing plate 41 along the left-and-right direction β. Two of the floating arms 43 are close to the bottom of the floating fixing seats 42 and are symmetrically arranged on the inner side walls of the two floating fixing seats 42. The fixing mechanism 44 is arranged between the two floating arms 43 and has a mounting end protruding from the bottom of the floating arms 43 for mounting the pneumatic chuck 500. The floating mechanism includes two floating cylinders 45 and two floating shafts 46. The two floating cylinders 45 are respectively and symmetrically mounted on the outer sides of the two floating fixing seats 42, and the output ends of the floating cylinders 45 are respectively connected to the corresponding floating arms 43, so as to be able to drive the floating arms 43 to move directionally by telescoping. The two floating shafts 46 are correspondingly and vertically inserted between the floating fixing seats 42 and the floating arms 43 on both sides. Conical roller bearings 461 suitable for connecting the floating fixing seats 42 and the floating arms 43 are respectively sleeved on both sides of the floating shafts 46 in the extending direction, and a thrust ball bearing 462 is sleeved at the middle position between the two conical roller bearings 461. The thrust ball bearing 462 is embedded in the floating arm 43, and the inner ring of the thrust ball bearing 462 and the floating shaft 46 are in clearance fit;

[0053] In this way, under the support of the tapered roller bearings 461 on both sides, when the floating cylinders 45 on both sides are synchronously extended or retracted, based on the gap between the thrust ball bearing 462 and the floating shaft 46, the floating arm 43 can be pushed to move in a certain range, thereby driving the product 400 at the installation end of the fixing mechanism 44 to move, flexibly adjusting the pressure between the product 400 and the grinding disc 700, or ensuring that the pressure between the product 400 and the grinding disc 700 is stable, and then when the product 400 just contacts the grinding disc 700, it can ensure that the product 400 will not have a strong hard contact with the grinding disc 700 to damage the product 400. 00, and at the same time, during the processing of the product 400, the processing quality of the product 400 can also be ensured. In the process of the product 400 contacting the grinding disc 700, the product 400 can be first brought close to but not in contact with the grinding disc 700, and then the floating cylinders 45 on both sides can be used to make the product 400 contact the grinding disc 700 and maintain a predetermined pressure. Alternatively, the product 400 can be first allowed to contact the grinding disc 700, and then the pressure between the product 400 and the grinding disc 700 can be adjusted by the floating cylinders 45 on both sides, wherein the pressure between the product 400 and the grinding disc 700 is monitored by the pressure sensor of the electrically controlled proportional valve in the floating cylinder 45.

[0054] Further preferably, the floating fixed seat 42 is provided with a mounting notch 401 on the inner side wall near the bottom, and at the same time, the top of the floating arm 43 is provided with a boss 431 that matches the mounting notch 401, and the floating shaft 46 is opposite to the boss 431, so that the overall structure of the moving mechanism 300 is more compact. At the same time, based on the cooperation between the mounting notch 401 and the boss 431, the floating fixed seat 42 and the floating arm 43 are facilitated to be quickly assembled, and a certain guiding effect can be provided to the movement of the floating arm 43 during the adjustment process.

[0055] Further preferably, a guide plate 421 and a guiding and limiting structure are respectively installed on the opposite front side wall and rear side wall of the floating fixing seat 42. The guide plate 421 extends to the floating arm and covers the top of the floating arm 43 to provide a guiding effect for the movement of the floating arm 43 during the adjustment process. The guiding and limiting structure includes a fixing block 422, a guiding block 423, and a fully threaded bolt 424. The fixing block 422 and the guiding block 423 are respectively installed on the floating fixing seat 42 and the floating arm 43 in the vertical direction. One end of the fully threaded bolt 424 is fixedly connected to the fixing block 422, and the other end passes through the guiding block 423 in a sliding fit manner and has a nut 425 located below the guiding block 423. At the same time, a nut 426 is sleeved on the fully threaded bolt 424 in a threaded fit manner, and the nut 426 is located between the guiding block 423 and the nut 425, so that the downward movement distance of the floating arm 43 can be limited by the nut 426, ensuring that the floating arm 43 will not move down a large distance due to an accident and damage the product 400. In addition, the position of the nut 426 can be rotated and adjusted to change the maximum downward movement distance of the floating arm 43, and the adjustment is more convenient and has a high flexibility.

[0056] Further preferably, in combination with Figures 9 to 11 , the fixing mechanism 44 includes a rotating element 441, a rotating sleeve 442, and a transfer shaft 443. The rotating element 441 is fixedly connected to the top end of the rotating sleeve 442 through a transfer sleeve 444. The transfer shaft 443 is embedded in the rotating sleeve 442, coaxially fixedly connected to the output end of the rotating element 441 at the top end, and coaxially fixedly connected to the pneumatic chuck 500 at the bottom end. The bottom end of the pneumatic chuck 500 is used to install the product 400. A bearing 445 is provided between the transfer shaft 443 and the rotating sleeve 442, and the rotating sleeve 442 is arranged between the two floating arms 43. Thus, based on the cooperation of the rotating sleeve 442 and the transfer shaft 443 through the bearing 445, the product 400 can be driven to rotate directionally by the rotating element 441, facilitating the one-time processing and forming of the product 400.

[0057] Further preferably, the two floating arms 43 are respectively defined as a first floating arm 432 and a second floating arm 433, wherein a first swing shaft 434 and a second swing shaft 435 capable of freely rotating are symmetrically arranged inside the first floating arm 432 and the second floating arm 433.

When the first rotating element 436 operates, its rotating output end drives the rotating sleeve 442 to rotate between the two floating arms 43 through the first swing shaft 434 and the second swing shaft 435, so that the product 400 can also generate a certain yaw in the front-back direction α, and cooperate with the rotating element 441 to drive the product to rotate directionally and quantitatively, which is more convenient for the product 400 to be formed in one-time processing. In addition, the symmetrical design of the first swing shaft 434 and the second swing shaft 435 can also effectively improve the stability of the rotation of the fixing mechanism 44, thereby ensuring the accuracy of the yaw direction and yaw amount of the product 400.

[0058] Further preferably, a protective cover 437 is installed on the outer wall of the second floating arm 433 opposite to the second swing shaft 435 for protecting the second swing shaft 435. At the same time, an adjusting rod 438 is connected between the two floating arms 43 for stabilizing the first floating arm 432 and the second floating arm 433.
