Description
Technical Field

[0002] In the sanitary ware hardware manufacturing industry, the polishing and grinding quality of pipe fittings directly affects the product's sealing performance and aesthetics. Traditional polishing and grinding equipment often uses mechanical chucks combined with telescopic ejector pins for clamping mechanisms. For example, utility model patent CN211277850U discloses a grinding component of a polishing device with an automatic adjustment function. This component uses a pneumatic cylinder to drive the inner and outer sleeves for height adjustment. While it can adapt to materials of different thicknesses, its clamping range is relatively small, and its rigid clamping structure is prone to radial deformation of the pipe fittings under vibration, resulting in microscopic indentations on the surface. Furthermore, the polishing pressure causes thin-walled pipes to deform elliptically, but existing equipment lacks a real-time feedback adjustment mechanism. Utility Model Content

[0035] like Figure 1 As shown, the present invention proposes an adjustment component for polishing and grinding, including a base 1 and a clamping seat 2 located on one side of the base 1. The clamping seat 2 is provided with a clamping device 4 for clamping the tube to be polished and ground. The base 1 is provided with a polishing and grinding device 3 that moves linearly along the tube to be polished and ground.
[0036] The polishing and grinding device 3 includes a movable seat 31 slidably mounted on the base 1, a telescopic rod 32 mounted on the movable seat 31, and a mounting seat 33 mounted on the telescopic rod 32. The telescopic rod 32 drives the mounting seat 33 to move along the z-direction. The mounting seat 33 is provided with a vertically mounted telescopic rod 34. The free end of the telescopic rod 34 is provided with a mounting plate 35. The telescopic rod 34 drives the mounting plate 35 to move along the y-direction. The mounting plate 35 is provided with a rotating polishing disc 36 on one side near the clamping seat 2. The other side of the mounting plate 35 is provided with a motor 37. The output shaft of the motor 37 is connected to the center of the polishing disc 36, driving the polishing disc 36 to rotate and perform polishing operations. The bottom of the polishing and grinding device 3 is provided with a linear drive device 7 slidably mounted between the fixed end 5 and the movable end 6. The linear drive device 7 drives the polishing and grinding device 3 to move along the x-direction.
[0037] refer to Figure 2 As shown, the linear drive device 7 includes a ball screw 71, a slide block 72, and a motor 73. The ball screw 71 is rotatably mounted inside the base 1. The slide block 72 has a threaded hole for threaded connection with the ball screw 71. The base 1 has a sliding hole 74 for sliding the movable seat 31. The slide block 72 is connected to the movable seat 31. The motor 73 is located on one side of the base 1, and the output shaft of the motor 73 is connected to the ball screw 71, thereby enabling the slide block 72 to move along the x-axis with the polishing disc 36. Furthermore, a slide rod 75 parallel to the ball screw 71 is provided inside the base 1, and the slide block 72 also has a sliding hole 74 matching the slide rod 75, which improves stability during movement and serves as a limit.
[0038] In this structure, the pipe fitting is first fixed using the clamping device 4. The telescopic rod 34 is adjusted to move the polishing disc 36 along the y-axis, ensuring the disc fits snugly against the pipe fitting. The telescopic rod 32 is used to adjust the z-axis position of the polishing disc 36, i.e., its height, allowing for multi-position adjustment and better fit against the pipe fitting. Once in contact with the pipe fitting, polishing is then performed. Next, the motor 37 is switched on, causing it to rotate and polish the disc 36, thus polishing the pipe fitting. During this process, the motor 73 drives the ball screw 71 to rotate, causing the slide 72 to connect threadedly to the ball screw 71 and move along the sliding hole 74 along the x-axis, polishing the pipe fitting in a straight line.
[0039] As a further explanation:
[0040] refer to Figure 3 and 4As shown, the slide bar 75 in the above scheme can be replaced with a second lead screw 76. The slide block 72 has a threaded hole matching the second lead screw 76. The slide block 72 is driven by two sets of parallel ball screws 71. In this case, a synchronous drive structure is provided between the second lead screw 76 and the ball screw 71. This synchronous drive structure includes a first worm gear 77 and a second worm gear 78 coaxially connected to the outside of the ball screw 71 and the second lead screw 76, respectively. A drive housing is provided on the outside of the base 1. The first worm gear 77 and the second worm gear 78 are rotatably mounted on the inner wall of the drive housing. A worm 79 meshing with the first worm gear 77 and the second worm gear 78 is also provided inside the drive housing. A third motor 73 is located on the outside of the drive housing. The output shaft of the third motor 73 is connected to the worm 79 to drive the worm 79 to rotate. In this structure, the slide block 72 slides along the two sets of lead screws, driving the polishing disc 36 to change position along the x-axis.
[0041] The purpose of this structural design is to solve the rocker effect in long-stroke polishing and to avoid the deterioration of precision caused by wear of the slide bar 75, thereby improving the performance. It can be used according to specific needs. Example
[0042] To address the issue of poor compatibility with pipe dimensions during clamping, refer to Figure 1 and Figure 4 As shown, the clamping device 4 includes a fixed end 5 and a movable end 6 respectively disposed on both sides of the clamping seat 2, and the pipe to be polished is clamped between the fixed end 5 and the movable end 6.
[0043] Combination Figure 1 and Figure 5 As shown, the fixed end 5 includes a chuck 51. A support rod 52 is fixedly connected to the clamping seat 2 at the bottom of the chuck 51. A clamping claw 53, driven by a telescopic rod 54, is provided on one side of the chuck 51. A positioning block 57 is fixedly connected between the telescopic rod and the chuck 51. The clamping claw 53 is connected to the free end of the telescopic rod 54. The clamping claw 53 is distributed circumferentially and moves synchronously towards the center. A piezoelectric ceramic plate 55 is embedded on the claw surface of the clamping claw 53. The piezoelectric ceramic plate 55 is connected to the telescopic rod 54 via a processor 58. The processor 58 can be located on one side of the support rod 52. When the processor 58 detects that the pressure exceeds a threshold, it automatically adjusts the stroke of the telescopic rod 54. In this structure, the piezoelectric ceramic monitoring on the inner wall of the clamping claw 53 of the chuck 51 is used to collect the radial pressure distribution of the pipe in real time, avoiding deformation caused by uneven pressure on the pipe.
[0044] In addition, a second motor 56 is provided at the top of the first support rod 52. The output shaft of the second motor 56 is connected to the center of the chuck 51. The second motor 56 drives the chuck 51 and the pipe clamped by the chuck 51 to rotate, causing the polishing disc 36 to change the polishing of one horizontal surface of the pipe to polishing of the circumference of the pipe.
[0045] As shown Figure 1 in the figure, the movable end 6 includes a lower clamping block 61 and an upper clamping block 62. A second support rod 63 is provided at the bottom of the lower clamping block 61 and is slidably connected to the clamping seat 2. Semi-circular positioning grooves 64 are provided at the centers of both the lower clamping block 61 and the upper clamping block 62. The positioning grooves 64 between the upper clamping block 62 and the lower clamping block 61 form a clamping hole 65 for fixing the pipe fitting to be clamped. The movable end 6 includes multiple sets of clamping holes 65 with different diameters.
[0046] Among them, multiple sets of the movable end 6 are provided. Different-diameter clamping holes 65 are formed between multiple sets of the upper clamping block 62 and the lower clamping block 61. A topological slideway 21 is provided on the clamping seat 2. A slider matching the topological slideway 21 is provided at the bottom of the second support rod 63. The topological slideway 21 is a connected topological network composed of at least two orthogonal rectangular loop units. The rectangular loop units are coupled and connected by sharing boundaries and are arranged along a single-axis direction. The number of the movable ends 6 can be set according to the common pipe diameters of the pipe fittings. Two orthogonal rectangular loop units can be combined into a structure like the Chinese character 'ri', and three orthogonal rectangular loop units can be combined into a structure like the Chinese character'mu'. Multiple sets of loop units can be set for expansion. Adjust the corresponding movable end 6 according to the diameter of the pipe fitting and move it to one side of the corresponding fixed end 5 for setting.
[0047] In this structure, the clamping device 4 is constituted by the fixed end 5 and the movable and replaceable movable end 6. The topological slideway 21 is used to achieve the rapid switching of multiple specifications of the movable end 6, realizing the rapid clamping and positioning effect of the pipe fitting.
[0048] As a further elaborated structure, the slider and the inner wall of the topological slideway 21 can be combined into an 'I'-shaped structure to limit the movement of the second support rod 63 and prevent it from sliding out of the topological slideway 21.
[0049] To facilitate the replacement of the clamped pipe fitting, mounting bosses 66 are provided on both sides of the upper clamping block 62 and the lower clamping block 61. A detachable bolt fixation is provided between the mounting bosses 66, and together with the quickly replaceable movable end 6, it further improves the speed of installation, disassembly, and replacement of the pipe fitting.
[0050] In addition, to solve the problem of scratches on the pipe fitting caused by the metal clamping jaws, a lining layer 67 is provided on the inner wall of the positioning groove 64. The lining layer 67 is made of nitrile rubber and will not cause scratches on the surface of the pipe fitting to be polished when contacting it, avoiding scratches and damage on the surface of the pipe fitting.
[0051] As a further elaborated embodiment:
[0052] As Figure 6As shown, the chuck 51 can be replaced with a common general-purpose chuck 51, including but not limited to hydraulically or pneumatically driven chucks 51 that drive the grippers 501. According to the number of jaws in the grippers 501, they are divided into three-jaw chucks, four-jaw chucks, etc. The side is provided with air holes 502 or oil holes to control the centripetal movement of the grippers. Similar to the drive of the telescopic rod 54, the inner wall of the gripper 501 is equipped with a piezoelectric ceramic plate 55. The pneumatic or hydraulic switch and the piezoelectric ceramic plate 55 are all connected to the processor 58 to control the clamping force and prevent the deformation of the pipe.
[0053] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
