Description

Technical Field

[0001] The present invention relates to the field of polishing processing of washbasins, and particularly to a swing-type grinding device for washbasins. Background Art

[0002] In the current production process of washbasins, in order to improve the smoothness of the inner wall of the washbasin at the final factory and reduce the stains adhering to the inner wall of the washbasin during use, it is necessary to polish the inner wall of the washbasin during production to reduce the roughness of the inner wall of the washbasin.

[0003] In the existing washbasin polishing process, there are usually two grinding methods. One is to drive the swing arm to swing to a suitable position by a motor, and then use the grinding wheel arranged at the end of the swing arm to perform grinding. The other is to drive the polishing belt by a pulley driven by a motor, and use the grinding surface of the polishing belt to grind the inner wall of the washbasin. The former cannot achieve a good grinding effect on the flat surface of the bottom of the inner wall of the washbasin, and the latter is prone to the situation where the grinding equipment interferes with the washbasin during the grinding process. Summary of the Invention

[0004] The present invention aims to solve at least one of the technical problems existing in the prior art. For this purpose, the present invention provides a swing-type grinding device for washbasins, which can achieve good grinding and polishing effects on both the flat surface and the concave surface of the inner wall of the washbasin, while reducing the occurrence of interference between the grinding equipment and the washbasin.

[0005] The swing-type grinding device for washbasins of the present invention includes: a frame; a swing bracket arranged on the frame, and the swing bracket can swing relative to the swing bracket; a swing arm telescopically arranged on the swing bracket; a grinding drive wheel rotatably arranged on the swing bracket; a grinding wheel rotatably connected to the end below the swing arm; a grinding belt, with both ends respectively connected to the grinding drive wheel and the grinding wheel, and can be linked under the action of the grinding drive wheel.

[0006] Furthermore, a driving device is arranged on the frame, and the driving device is used to drive the swing bracket to rotate.

[0007] Furthermore, the driving device includes a swing motor arranged on the frame, the swing motor is drivingly connected with a driving gear, the swing bracket is connected with a driven gear, and the driven gear meshes with the driving gear.

[0008] Furthermore, the driving device includes a swing motor arranged on the frame, the swing motor is drivingly connected with an eccentric wheel, and the eccentric wheel is connected with the swing bracket.

[0009] Furthermore, the swing motor is a stepping motor.

[0010] Further, a telescopic cylinder is provided on the swing bracket. The telescopic cylinder can drive the swing arm to extend downward. A driven pulley is rotatably connected to the upper end of the swing arm, and the driven pulley is connected to the grinding belt.

[0011] Further, a tensioning roller is provided on the swing bracket, and the tensioning roller abuts against the grinding belt.

[0012] Further, two tensioning rollers are provided on the swing bracket, and the two tensioning rollers are respectively located at the upper end and the lower end of the grinding drive wheel.

[0013] Further, a slider is provided on the swing bracket. The slider is slidably connected to the swing bracket, and the grinding drive wheel is rotatably arranged on the slider.

[0014] Further, a lead screw is rotatably connected to the swing bracket. The lead screw is in threaded cooperation with the slider, and one end of the lead screw is connected with a handwheel.

[0015] When applying the swing-type grinding device for a washbasin of the present invention to grind the concave surface of the inner wall of the washbasin, the swing arm can be controlled to swing relative to the frame to a suitable position, so that the grinding wheel moves along an arc to the concave surface of the inner wall of the washbasin driven by the swing arm. Then, the grinding drive wheel is controlled to drive the grinding belt to rotate, so that the grinding belt can grind the concave surface of the inner wall of the washbasin. Compared with the prior art in which the grinding wheel approaches the concave surface by means of lifting, the swing method adopted in the present invention to make the grinding wheel approach the concave surface can effectively reduce the interference between the grinding equipment and the washbasin; when grinding and polishing the flat surface of the inner wall of the washbasin, the swing arm can be telescoped while the swing bracket is swinging, so that the movement track of the grinding assembly at the end of the swing arm is as flat as possible. Compared with the non-telescopic swing-arm grinding device, the grinding effect on the flat surface is greatly improved, and good grinding and polishing effects can be achieved on both the flat surface and the concave surface.

[0026] The embodiments of the present invention will be described in detail below. The examples of the embodiments are shown in the drawings, in which the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by referring to the drawings are exemplary and are only used to explain the present invention and should not be construed as a limitation to the present invention.

[0028] In the description of the present invention, the meaning of several is one or more, the meaning of multiple is more than two, greater than, less than, exceeding, etc. are understood as not including the present number, and above, below, within, etc. are understood as including the present number. If there is a description of first and second, it is only for the purpose of distinguishing technical features and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features or implicitly indicating the sequence relationship of the indicated technical features.

[0029] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installation, connection, etc. should be understood in a broad sense, and those skilled in the art can reasonably determine the specific meanings of the above terms in the present invention in combination with the specific content of the technical solution.

[0030] In the first aspect of this embodiment, referring to Figures 1 to 5 , a swinging telescopic grinding device is provided, which is characterized in that it includes: a frame 100; a swinging bracket 200, arranged on the frame 100, and the swinging bracket 200 can swing relative to the frame 100; a swing arm 220, telescopically arranged on the swinging bracket 200; and a grinding assembly, arranged at the end below the swing arm 220.

[0031] When applying the swing telescopic grinding device of the first aspect of this embodiment to grind and polish the concave surface of the inner wall of the washbasin 400, the swing bracket 200 can be controlled to swing to the position corresponding to the concave surface of the inner wall of the washbasin 400, so that the grinding assembly can grind the concave surface, reducing the interference problem caused by moving the grinding assembly in a translational manner; when grinding and polishing the flat surface of the inner wall of the washbasin 400, while the swing bracket 200 is swinging, the telescopic swing arm 220 can be extended and retracted, so that the movement trajectory of the grinding assembly at the end of the swing arm 220 is as close to the flat surface as possible. Compared with the non-telescopic swing arm 220 type grinding device, the grinding effect on the flat surface is greatly improved, and good grinding and polishing effects can be achieved on both the flat surface and the concave surface.

[0032] Among them, the swing bracket 200 can swing relative to the frame 100 either by manual driving or by setting a motor eccentric wheel driving device, a hydraulic cylinder reciprocating driving device, etc., to realize the automatic swing of the swing bracket 200.

[0033] It can be understood that the swing arm 220 can be actively extended and retracted relative to the swing bracket 200 by setting a cylinder or a linear motor, etc., or a driving device can be not set, and the swing arm 220 can be set to be floating relative to the swing bracket 200. When the swing arm 220 passes over the flat surface of the inner wall of the washbasin 400, after the swing arm 220 is abutted by the body of the washbasin 400, it can be automatically extended and retracted.

[0034] It should be noted that the grinding assembly can also grind the inner wall of the washbasin 400 in various ways. For example, the inner wall of the washbasin 400 can be ground by sandpaper or grinding wheels fixedly arranged at the lower end of the swing arm 220, or a hub motor can be arranged at the lower end of the swing arm 220, and a grinding wheel can be sleeved on the outer periphery of the hub motor, and the inner wall of the washbasin 400 can be ground and polished by the rotation of the grinding wheel.

[0035] As Figure 2 shown, in order to realize the automatic control of the swing of the swing bracket 200 and facilitate the precise control of the swing position of the swing bracket 200, a driving device is arranged on the frame 100, and the driving device is used to drive the swing bracket 200 to rotate.

[0036] As Figure 6 shown, the inner wall surface of the washbasin 400 is composed of a concave part and a flat part. During production, both the concave part and the curved part need to be polished.

[0037] Further as Figure 1 、 Figure 2As shown in the figure, the driving device includes a swing motor 110 arranged on the frame 100. The swing motor 110 is drivingly connected with a driving gear 120. The swing bracket 200 is connected with a driven gear 130, and the driven gear 130 meshes with the driving gear 120. Among them, when the motor rotates forward and backward alternately, the swing bracket 200 can swing relative to the swing bracket 200 under the drive of the gear. Using gear transmission can effectively ensure the accuracy of transmission.

[0038] As Figure 2 shown in the figure, here, since the swing bracket 200 only needs to swing relative to the frame 100 and does not need to rotate a full circle, the driven gear 130 does not need to be provided with a full-circle complete gear. Only the part of the gear as shown in the figure is needed to meet the swing stroke, which can also play a role in saving the self-weight of the gear and reducing the load of the motor.

[0039] Of course, an eccentric wheel can also be drivingly connected to the swing motor 110, and the eccentric wheel is connected to the swing bracket 200. By driving the eccentric wheel to rotate, the swing bracket 200 is driven to swing. At this time, only the driving motor needs to rotate in one direction, and there is no need to control the motor to rotate forward and backward alternately.

[0040] Due to the need to facilitate the control of the position and forward and backward rotation state of the motor, a stepper motor can be used as the swing motor 110.

[0041] As Figure 1 shown in the figure, in order to actively control the telescopic state of the swing arm 220 relative to the swing bracket 200, a telescopic cylinder 210 is arranged on the swing bracket 200, and the telescopic cylinder 210 can drive the swing arm 220 to telescope.

[0042] As Figure 3 、 Figure 4 shown in the figure, in order to enable the swing arm 220 to better adapt to washbasins 400 of different depths, an extension arm 230 can be arranged below the swing arm 220. A grinding assembly is arranged at the end of the lower end of the extension arm 230, and the extension arm 230 is detachably connected to the swing arm 220.

[0043] Furthermore, in order to adjust the extension distance of the extension arm 230, a plurality of fixing holes are arranged on the extension arm 230. A screw passes through one of the fixing holes and is threadedly connected to the extension arm 230. When the extension distance needs to be adjusted, it can be achieved by passing the screw through different fixing holes and threadedly connecting it to the swing arm 220.

[0044] As Figures 1 to 5As shown, in the second aspect of this embodiment, a wash basin 400 grinding device is provided, including: a frame 100; a swing arm 220, which is arranged on the frame 100 and can swing relative to the frame 100; a grinding drive wheel 320, which is rotatably arranged on the frame 100; a grinding wheel 380, which is rotatably connected to the end below the swing arm 220; and a grinding belt 340, whose two ends are respectively connected to the grinding drive wheel 320 and the grinding wheel 380, and can be linked under the action of the grinding drive wheel 320.

[0045] The wash basin 400 grinding device according to the second aspect of the present embodiment can be used to control the swing arm 220 to swing to a suitable position relative to the frame 100, so that the grinding wheel 380 moves along a circular arc to the concave surface of the inner wall of the wash basin 400 driven by the swing arm 220, and then the grinding drive wheel 320 is controlled to drive the grinding belt 340 to rotate, so that the grinding belt 340 can grind the concave surface of the inner wall of the wash basin 400. Compared with the prior art that uses a lifting method to make the grinding wheel 380 close to the concave surface, the present invention uses a swinging method to make the grinding wheel 380 close to the concave surface, which can effectively reduce the interference between the grinding equipment and the wash basin 400.

[0046] The grinding drive wheel 320 can drive the grinding belt 340 to rotate in various ways, such as manually rotating the grinding drive wheel 320 to drive the grinding belt 340 to rotate, or driving the grinding drive wheel 320 to rotate by a motor or a rotary cylinder.

[0047] like Figure 2 As shown, in order to enable the grinding belt 340 to better grind the plane of the inner wall of the wash basin 400, a swing bracket 200 is provided on the frame 100, and the swing bracket 200 can swing relative to the frame 100. The swing arm 220 is telescopically arranged on the swing bracket 200, and the grinding drive wheel 320 is rotatably arranged on the swing bracket 200; at this time, the grinding drive wheel 320 can move along the plane as much as possible by swinging and telescoping, thereby greatly improving the grinding effect of the plane.

[0048] Furthermore, in order to facilitate the driving of the grinding drive wheel 320 to rotate and to facilitate the arrangement of the position of the drive device, a grinding motor 300 is provided on the swing bracket 200. The grinding motor 300 drives the grinding drive wheel 320 to rotate through a synchronous belt 310. At this time, the grinding motor 300 can be arranged off-axis with the grinding drive wheel 320.

[0049] like Figure 2 As shown, in order to facilitate the tension of the grinding belt 340, a slider 360 is provided on the swing bracket 200, the slider 360 is slidably connected to the swing bracket 200, and the grinding drive wheel 320 is rotatably set on the slider 360; at this time, the belt tension can be adjusted by simply adjusting the position of the slider 360.

[0050] Further, in order to lock the slider 360 after adjusting its position, a lead screw is rotatably connected to the swing bracket 200, and the lead screw is in threaded engagement with the slider 360. At this time, the reverse self-locking property of the lead screw can be used to lock the position of the slider 360.

[0051] To facilitate the rotation of the lead screw, a handwheel 370 is connected to one end of the lead screw.

[0052] As Figure 2 shown, a driven pulley 350 is rotatably connected to the upper end of the swing arm 220, and the driven pulley 350 is connected to the grinding belt 340.

[0053] Further, in order to prevent the included angle of the grinding belt 340 at the grinding wheel 380 from being too large, which may affect the swing range of the swing arm 220, a tension roller 330 is provided on the swing bracket 200, and the tension roller 330 abuts against the grinding belt 340.

[0054] Specifically, two tension rollers 330 are provided on the swing bracket 200, and the two tension rollers 330 are respectively located above and below the grinding drive pulley 320.

[0055] As Figures 1 to 5 shown, the swing-type grinding device for the washbasin 400 according to the third aspect of this embodiment includes: a frame 100; a swing bracket 200 provided on the frame 100, and the swing bracket 200 can swing relative to the swing bracket 200; a swing arm 220 telescopically provided on the swing bracket 200; a grinding drive pulley 320 rotatably provided on the swing bracket 200; a grinding wheel 380 rotatably connected to the end below the swing arm 220; a grinding belt 340 with both ends respectively connected to the grinding drive pulley 320 and the grinding wheel 380, and capable of being linked under the action of the grinding drive pulley 320.

[0056] When using the swing-type grinding device for the washbasin 400 according to the third aspect of this embodiment to grind the concave surface of the inner wall of the washbasin 400, the swing arm 220 can be controlled to swing relative to the frame 100 to an appropriate position, so that the grinding wheel 380 moves along an arc driven by the swing arm 220 to the concave surface of the inner wall of the washbasin 400. Then, the grinding drive wheel 320 is controlled to drive the grinding belt 340 to rotate, so that the grinding belt 340 can grind the concave surface of the inner wall of the washbasin 400. Compared with the prior art in which the grinding wheel 380 approaches the concave surface by means of lifting, the swing method adopted in the present invention to make the grinding wheel 380 approach the concave surface can effectively reduce the interference between the grinding equipment and the washbasin 400; when grinding and polishing the flat surface of the inner wall of the washbasin 400, the swing arm 220 can be telescoped while the swing bracket 200 is swinging, so that the movement trajectory of the grinding assembly at the end of the swing arm 220 is as flat as possible. Compared with the non-telescopic swing arm 220 type grinding device, the grinding effect on the flat surface is greatly improved, and good grinding and polishing effects can be achieved on both the flat surface and the concave surface.

[0057] As Figure 1 、 Figure 2 shown, in order to realize the automatic control of the swing of the swing bracket 200, a driving device is provided on the frame 100, and the driving device is used to drive the swing bracket 200 to rotate.

[0058] Further, the driving device includes a swing motor 110 provided on the frame 100. The swing motor 110 is drivingly connected with a driving gear 120. The swing bracket 200 is connected with a driven gear 130, and the driven gear 130 meshes with the driving gear 120.

[0059] In order to reduce the alternating forward and reverse rotation of the swing motor 110 and extend the service life of the motor, the driving device includes a swing motor 110 provided on the frame 100. The swing motor 110 is drivingly connected with an eccentric wheel, and the eccentric wheel is connected with the swing bracket 200; at this time, the swing motor 110 only needs to rotate in one direction and does not need to alternate forward and reverse.

[0060] For the purpose of facilitating the control of the swing, the swing motor 110 is a stepping motor.

[0061] As Figure 1 shown, in order to automatically control the telescoping of the swing arm 220 and better grind the flat surface of the inner wall of the washbasin 400, a telescopic cylinder 210 is provided on the swing bracket 200. The telescopic cylinder 210 can drive the swing arm 220 to extend downward. The upper end of the swing arm 220 is rotatably connected with a driven pulley 350, and the driven pulley 350 is connected with the grinding belt 340.

[0062] As Figure 1As shown, in order to avoid an excessive angle of the grinding belt 340 at the grinding wheel 380, which may affect the swing range of the swing arm 220, a tensioning roller 330 is provided on the swing bracket 200, and the tensioning roller 330 abuts against the grinding belt 340.

[0063] Furthermore, two tensioning rollers 330 are provided on the swing bracket 200, and the two tensioning rollers 330 are respectively located at the upper and lower ends of the grinding drive wheel 320.

[0064] In order to facilitate the adjustment of the position of the grinding drive wheel 320 and further adjust the tension of the grinding belt 340, a slider 360 is provided on the swing bracket 200. The slider 360 is slidably connected to the swing bracket 200, and the grinding drive wheel 320 is rotatably arranged on the slider 360.

[0065] Furthermore, a lead screw is rotatably connected to the swing bracket 200. The lead screw is in threaded cooperation with the slider 360, and one end of the lead screw is connected to a handwheel 370.
