Description

Technical Field

[0001] The utility model relates to the technical field of polishing machines, in particular to an all-round precision polishing machine. Background Art

[0002] Polishing machines, also known as grinders, are often used for mechanical grinding, polishing and waxing. Their working principle is that the motor drives the sponge or wool polishing disc installed on the polishing machine to rotate at high speed. Due to the joint action of the polishing disc and the polishing agent and the friction with the surface to be polished, the paint surface pollution, oxide layer and shallow marks can be removed.

[0003] Prior art, such as patent publication number CN220881865U, discloses a polishing machine for precision parts processing, comprising a worktable, the top of which is fixedly connected to a rotating seat, the outer portion of which is rotatably connected to an adjustment platform, a hydraulic push rod hinged on the side wall of the rotating seat, the output end of the hydraulic push rod hinged to the adjustment platform, the top of the adjustment platform fixedly connected to a placement platform, the interior of the placement platform having a movable groove, the inner wall of which is fixedly connected to a slide rod, the outer portion of which is slidably connected to a sliding sleeve, the top of the sliding sleeve fixedly connected to a fixed clamping block, the bottom of which is fixedly connected to a first wedge block, the top of the adjustment platform rotatably connected to a rotating sleeve, the inner side wall of the rotating sleeve fixedly connected to a second wedge block that contacts the inclined surface of the first wedge block. This polishing machine for precision parts processing simultaneously fixes the parts on all sides using four fixed clamping blocks, thus having the advantage of stable clamping.

[0004] In actual use, after polishing one surface of a part, the part surface needs to be replaced so that the surface to be polished and the polishing device are aligned. Replacing the part surface requires re-clamping the part, which affects the polishing efficiency; the polishing device makes it difficult to polish the position where the fixed clamp is clamped on the part surface.

[0005] Therefore, it is necessary to provide a new technical solution to overcome the above-mentioned defects. Utility Model Content

[0006] The purpose of this utility model is to provide a comprehensive precision polishing machine which can effectively solve the above technical problems.

[0007] In order to achieve the purpose of the utility model, the following technical solution is adopted: an all-round precision polishing machine, comprising: an electric telescopic column, a rotating assembly for driving the worktable to rotate, a clamping assembly for clamping the workpiece, and a polishing assembly capable of adjusting the polishing angle;

[0008] The rotating assembly includes: a workbench, a ring gear fixedly installed at the bottom of the workbench, a third gear meshing with the ring gear, a third motor driving the third gear to rotate, and a connecting plate connecting the third motor and the support block, and the support block is rotatably installed at the bottom of the workbench.

[0009] Furthermore, the polishing assembly includes: a mounting rod, a rotating rod rotatably mounted at the lower end of the mounting rod, an electric push rod hinged at both ends to the mounting rod and the rotating rod respectively, a fourth motor fixedly mounted on the rotating rod, and a polishing disc fixedly mounted on the output end of the fourth motor.

[0010] Furthermore, the clamping assembly includes: a first bevel gear, a plurality of second bevel gears meshing with the first bevel gear, a third threaded rod fixed through the second bevel gears, a moving block threadedly mounted on the third threaded rod, and a telescopic assembly arranged on the moving block.

[0011] Furthermore, the telescopic assembly includes: a clamping block, a first fixed plate symmetrically fixedly installed on the clamping block, a second fixed plate symmetrically fixedly installed on the moving block, and a limiting rod fixedly installed on the second fixed plate, wherein the limiting rod passes through the through hole on the first fixed plate and surrounds a spring installed on the limiting rod.

[0012] Furthermore, an anti-slip pad is fixedly installed on the clamping block.

[0013] Compared with the prior art, the present invention has the following beneficial effects: the present invention is a comprehensive precision polishing machine. When the polishing of one side of the workpiece is completed, the third motor is started, the third gear drives the ring gear to rotate, and the ring gear drives the workbench to rotate, and the surface of the workpiece to be polished is replaced. At the same time, the stretching of the electric push rod pushes the rotating rod to adjust the angle of the polishing disc, so that the polishing disc can grind the inclined surface of the workpiece without loosening the clamping for adjustment, thereby improving the polishing efficiency.
