Description

Technical Field

[0001] The invention relates to the technical field of polishing processing, in particular to a surface polishing device for processing doors, windows and curtain walls. Background Art

[0002] Doors, windows and curtain walls are a general term for the building's external protective structure, mainly including doors, windows and curtain wall systems of the building's exterior walls. Doors and windows, as channels connecting the interior and exterior spaces of a building, have functions such as lighting, ventilation, heat preservation and sound insulation; while curtain walls, as the exterior walls of a building, not only play a role in enclosure and decoration, but also carry certain structural functions, with characteristics such as windproof, rainproof, sunscreen and heat preservation. Modern door, window and curtain wall design focuses on energy saving, environmental protection and aesthetics, and uses advanced materials and processes, becoming an important element in improving building quality and comfort.

[0003] With the improvement of living standards, most high-rise buildings now use doors, windows and curtain walls. Polishing doors, windows and curtain walls is to improve their beauty, durability and functionality. The polishing process mainly includes removing surface burrs, oil stains and dust, smoothing edges and corners, and enhancing coating adhesion. Through polishing, the surface of doors, windows and curtain walls is smoother and flatter, and the coating adhesion is stronger, thereby improving the overall quality and service life, while meeting the dual needs of building beauty and practicality.

[0004] The polishing process mainly includes preliminary preparation. In the polishing process, in order to ensure the polishing effect, it is usually necessary to go through coarse grinding, medium grinding and fine grinding.

[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0032] Example 1: This example is intended to help solve the problem that manually replacing the grinding wheel will reduce the polishing efficiency. Figures 1 to 9 A surface polishing device for door, window and curtain wall processing includes a top plate 1, a moving device 2 is installed at the bottom of the top plate 1, the moving device 2 includes an electric push rod 25 arranged at the bottom of the top plate 1, a folding line mounting plate 26 is installed at the output end of the electric push rod 25, and a wheel changing device 3 is installed on the side wall of the folding line mounting plate 26.

[0033] The moving device 2 includes a No. 1 slide rail 21 fixedly connected to the bottom of the top plate 1, a slide rod 22 slidably connected inside the No. 1 slide rail 21, a slide groove 23 is provided inside the slide rod 22, a slider 24 is slidably connected inside the slide groove 23, and an electric push rod 25 is fixedly connected to the bottom of the slider 24.

[0034] The configuration of the mobile device 2 is intended to accurately control the relative position of the polishing wheel 34 to ensure the position accuracy and integrity of the polishing range when polishing doors, windows and curtain walls. Specifically, the slide bar 22 can slide smoothly along the No. 1 slide rail 21 under the drive of the motor and screw drive system. At the same time, the slider 24 can also achieve precise movement in the slide groove 23 under the action of another set of motors and screw drive mechanisms. This design strategy, through a dual sliding adjustment mechanism, can flexibly adjust the polishing position of the polishing wheel 34 to meet the needs of precise polishing of different areas of doors, windows and curtain walls (its specific driving method and working principle are prior art, and this solution will not be described in detail).

[0035] The wheel changing device 3 includes a wheel changing motor 31 fixedly connected to one end of the folding line mounting plate 26, and the output end of the wheel changing motor 31 is fixedly connected to a wheel changing cylinder 32, a grinding wheel mounting groove 33 is provided in the wheel changing cylinder 32, a polishing grinding wheel 34 is installed in the grinding wheel mounting groove 33, and the polishing grinding wheel 34 is driven by the working device 4.

[0036] The structure of the wheel changing device 3 is to realize the efficient replacement of the polishing grinding wheel 34 to meet the process conversion requirements from rough grinding to fine polishing. The device drives the wheel changing cylinder 32 to rotate through the driving action of the wheel changing motor 31. This rotation action allows the polishing grinding wheels 34 equipped with sandpaper of different grits to be presented in sequence, especially when the rough grinding stage is completed, the polishing grinding wheel 34 equipped with medium sandpaper can be quickly rotated to the operating position. Subsequently, through the precise docking of the connecting device 5, the selected polishing grinding wheel 34 is firmly connected to the working device 4 to ensure the continuity and stability of the polishing operation.

[0037] The wheel changing cylinder 32 is cleverly equipped with polishing wheels 34 of various sizes and specifications. This design not only simplifies the replacement process of the grinding wheel during polishing, but also significantly improves the replacement efficiency. Compared with the traditional manual replacement method, the degree of automation is greatly improved. This improvement not only ensures the efficient execution of the polishing process, but also effectively shortens the operation cycle, further improving the overall production efficiency and quality control level of the polishing work.

[0038] The working device 4 includes a working motor 41 fixedly connected to the other end of the fold line mounting plate 26, the output end of the working motor 41 is fixedly connected to a telescopic outer shell 42, a telescopic inner rod 43 is slidably connected inside the telescopic outer shell 42, a polishing grinding wheel 34 is installed at the bottom of the telescopic inner rod 43, and the telescopic inner rod 43 is connected to the polishing grinding wheel 34 by a connecting device 5.

[0039] An independent annular groove 45 is formed at the top of the telescopic inner rod 43 , an independent annular block 46 is rotatably connected in the independent annular groove 45 , a telescopic spring 44 is fixedly connected to the top of the independent annular block 46 , and the other end of the telescopic spring 44 is fixedly connected in the telescopic outer shell 42 .

[0040] A spiral track groove 47 is defined in the telescopic outer shell 42 , a spiral slider 48 is slidably connected in the spiral track groove 47 , and the spiral slider 48 is fixedly connected to the side wall of the telescopic inner rod 43 .

[0041] The working device 4 is designed to drive the polishing wheel 34 to perform polishing work. The working motor 41 drives the polishing wheel 34 to rotate through the connection between the telescopic outer shell 42, the telescopic inner rod 43, and the connecting device 5. When the new polishing wheel 34 rotates to the bottom of the working motor 41, the working motor 41 drives the telescopic outer shell 42 to rotate. Since a spiral track groove 47 and a spiral slider 48 are provided between the telescopic outer shell 42 and the telescopic inner rod 43, the telescopic outer shell 42 starts to rotate under the drive of the working motor 41 and drives the telescopic inner rod 43 to slide downward. This design helps to ensure the connection between the telescopic inner rod 43 and the polishing wheel 34. Through the sliding of the telescopic inner rod 43, the connecting device 5 can be driven to connect the polishing wheel 34 with the telescopic inner rod 43, providing a stable connection for the working motor 41 to drive the polishing wheel 34 to work.

[0042] Before the polishing wheel 34 is fully connected to the telescopic inner rod 43, the telescopic inner rod 43 and the telescopic outer shell 42 are in a state of relative rotation. When the spiral slider 48 on the side wall of the telescopic inner rod 43 slides to the lowest end of the spiral track groove 47, the telescopic outer shell 42 will drive the telescopic inner rod 43 to rotate. Through this design, the working motor 41 cannot drive the polishing wheel 34 to rotate when the polishing wheel 34 and the telescopic inner rod 43 are fully connected, which effectively ensures the stability of the connection process of the connecting device 5.

[0043] Embodiment 2, this embodiment is intended to promote the solution of the problem of stability of the connection between the polishing wheel 34 and the telescopic inner rod 43 after the position of the polishing wheel 34 is changed. This embodiment is an explanation based on the embodiment 1. For details, please refer to Figures 1 to 9 The connecting device 5 includes a plug-in groove 51 opened in the polishing grinding wheel 34, the bottom of the telescopic inner rod 43 is plugged into the plug-in groove 51, a connecting ring groove 52 is opened in the telescopic inner rod 43, a fixed tooth block 53 is fixedly connected in the connecting ring groove 52, and a plug-in tooth block 54 is plugged between the fixed tooth blocks 53. The plug-in tooth block 54 is slidably connected in the plug-in slide groove 59, and the plug-in slide groove 59 is opened in the polishing grinding wheel 34.

[0044] The polishing grinding wheel 34 is located at the bottom of the plug-in groove 51 and is provided with a drive mounting groove 55, in which a drive block 56 is slidably connected, and a drive spring 57 is fixedly connected to the bottom of the drive block 56, and the other end of the drive spring 57 is fixedly connected to the drive mounting groove 55. The bottom of the drive mounting groove 55 is connected to a hydraulic channel 58, and the other end of the hydraulic channel 58 is connected to the plug-in slide groove 59.

[0045] The tail end of the plug-in tooth block 54 is fixedly connected to a No. 1 buffer spring 511, the other end of the No. 1 buffer spring 511 is fixedly connected to a buffer plate 510, the other end of the buffer plate 510 is fixedly connected to a No. 2 buffer spring 512, and the other end of the No. 2 buffer spring 512 is fixedly connected in the plug-in slot 59.

[0046] The connection device 5 is designed to ensure a stable connection between the polishing wheel 34 and the telescopic inner rod 43. When the telescopic inner rod 43 slides downward and is inserted into the plug-in slot 51, the bottom of the telescopic inner rod 43 contacts the drive block 56 and drives the drive block 56 to slide downward. Since a hydraulic channel 58 is provided at the bottom of the drive block 56, the buffer plate 510 at the other end of the hydraulic channel 58 and the No. 1 buffer spring 511, the No. 2 buffer spring 512 and the plug-in tooth block 54 fixedly connected to the buffer plate 510 are driven to slide to the right through the communication of the hydraulic channel 58, so that when the telescopic inner rod 43 is not fully inserted into the plug-in slot 51, the connecting ring groove 52 and the plug-in tooth block 54 are connected. The slide grooves 59 are not flush with each other, so the No. 1 buffer spring 511 will be in a compressed state, and the No. 2 buffer spring 512 will be in a stretched state under the drive of the drive block 56. When the telescopic inner rod 43 is fully inserted into the plug-in groove 51, driven by the No. 1 buffer spring 511, the plug-in tooth block 54 will be directly inserted into the gap between the fixed tooth block 53 in the connecting ring groove 52. At this time, the telescopic inner rod 43 and the polishing grinding wheel 34 are fixedly connected, and can be rotated under the drive of the working motor 41. Through this design, the stable connection between the telescopic inner rod 43 and the polishing grinding wheel 34 is effectively guaranteed, and the stable progress of the polishing process is guaranteed.

[0047] After polishing is completed, the working motor 41 only needs to rotate in the reverse direction to disconnect the telescopic inner rod 43 from the polishing grinding wheel 34 .

[0048] Embodiment 3, this embodiment is intended to promote the solution of the problem of further improving the connection stability between the telescopic inner rod 43 and the polishing grinding wheel 34. This embodiment is an explanation based on the embodiment 2. For details, please refer to Figures 1 to 9 A pressing assembly 6 is provided between the polishing grinding wheel 34 and the wheel changing cylinder 32. The pressing assembly 6 includes a pressing groove 61 opened in the wheel changing cylinder 32, a pressing plate 62 is slidably connected in the pressing groove 61, a pressing spring 63 is fixedly connected to the bottom of the pressing plate 62, and the other end of the pressing spring 63 is fixedly connected in the pressing groove 61, and a rotating groove 64 is opened in the wheel changing cylinder 32.

[0049] The downward pressure groove 61 and the downward pressure plate 62 are designed to be rectangular, which effectively ensures the stability of the polishing wheel 34 before replacement and avoids the polishing wheel 34 from rotating or falling off due to unexpected circumstances. At the same time, this downward pressure design allows the polishing wheel 34 to be stored in the wheel changing cylinder 32 when it is not rotating, effectively avoiding wear caused by external factors and effectively protecting the polishing wheel 34.

[0050] After the polishing wheel 34 is connected to the telescopic inner rod 43 by the connection device 5, the telescopic inner rod 43 will continue to drive the polishing wheel 34 to slide downward a certain distance under the drive of the working motor 41. At this time, the lower pressure plate 62 fixedly connected to the outer wall of the polishing wheel 34 will slide downward to the rotating groove 64. At this time, under the drive of the working motor 41, the rectangular lower pressure plate 62 can rotate in the annular rotating groove 64. This design enables the polishing wheel 34 to have different functions in different states.

[0051] A limiting assembly 7 is disposed in the polishing wheel 34 . The limiting assembly 7 includes a first slide groove 71 provided in the polishing wheel 34 . A first rack 74 is slidably connected in the first slide groove 71 . One end of the first rack 74 abuts against the buffer plate 510 .

[0052] A No. 2 slide groove 72 and a circular groove 73 are provided in the polishing grinding wheel 34. A No. 2 rack 75 is slidably connected in the No. 2 slide groove 72, and a transmission gear 76 is rotatably connected in the circular groove 73. The side wall of the transmission gear 76 is meshingly connected with the No. 1 rack 74 and the No. 2 rack 75. One end of the No. 2 rack 75 is fixedly connected to a return spring 79, and the other end of the return spring 79 is fixedly connected in the No. 2 slide groove 72. The other end of the No. 2 rack 75 is fixedly connected to a triangular slider 77, which is inserted in the triangular slide groove 78, and the triangular slide groove 78 is provided in the wheel changing cylinder 32.

[0053] After the polishing wheel 34 descends, the No. 2 rack 75 abutted by the side wall of the wheel changing cylinder 32 and the triangular slider 77 fixedly connected to one end of the No. 2 rack 75 will be inserted into the triangular slide groove 78 under the action of the reset spring 79. At this time, the No. 1 rack 74 is driven to slide to the left through the transmission gear 76, and one end of the No. 1 rack 74 is driven to abut against the buffer plate 510. At this time, the plug-in tooth block 54 will not be able to slide backward and will be in a stuck state. Through this design, the stability of the connection between the polishing wheel 34 and the telescopic inner rod 43 is further guaranteed.

[0054] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.

[0055] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
