Description

Technical Field

[0001] The utility model relates to the technical field of metal part processing, and particularly relates to a small part polishing device. Background Technique

[0002] Metal is a substance with luster, malleability, electrical conductivity, thermal conductivity, etc. After different metal products are processed, the surfaces of the metal products will be very rough and have many burrs. The burrs not only affect the finished products of the metal products, but also cause harm to the staff.

[0003] In traditional equipment, sandpaper needs to be replaced when grinding the metal surface, which is a troublesome process and wastes manpower.

[0004] A Chinese patent (authorization announcement number: CN117506675A) proposes a metal part polishing device, including a machine table. The top of the machine table is connected with a machine case. There is a polishing chamber in the machine case. The top of the polishing chamber is connected with a polishing mechanism. On both sides of the middle of the bottom end in the machine case, first electric push rods are symmetrically connected. The telescopic ends of the symmetric first electric push rods are connected with a part table. The middle of the top of the part table is rotationally connected with a secondary stabilizing table. On both sides of the top of the secondary stabilizing table, second electric push rods are symmetrically connected. The tops of the paired second electric push rods are both connected with part clamping parts. The advantages of this invention compared with the prior art are: providing a metal part polishing device that can effectively clean burrs, reduce secondary damage to the metal, has a good fixing effect on the metal surface, and can arbitrarily polish and grind the front and back sides.

[0005] In traditional equipment, replacing sandpaper is a relatively troublesome process and wastes manpower, greatly reducing work efficiency. To solve the problem that replacing sandpaper is a relatively troublesome process and wastes manpower, for this reason, we propose a small part polishing device. Content of the Utility Model

[0006] Aiming at the deficiencies of the prior art, the utility model provides a small part polishing device, which solves the problems in the background.

[0007] To achieve the above purposes, the utility model is realized through the following technical solutions:

[0008] A small part polishing device, including a mounting base, five support legs for support are fixedly connected to the bottom of the mounting base, a fixing mechanism for fixing parts is fixedly connected to the upper end surface of the mounting base, two electric retractable rods are fixedly connected to the upper end surface of the mounting base, and the two electric retractable rods are symmetrically distributed. A fixing disc is fixedly connected between the two electric retractable rods. A first driving motor is fixedly installed on the upper end of the fixing disc. The output end of the first driving motor is fixedly connected with a mounting plate, and a polishing mechanism for polishing parts is fixedly connected to the bottom of the mounting plate.

[0009] As a further improvement of this solution, the fixing mechanism includes a limiting disc, the limiting disc is fixedly connected to the upper end surface of the mounting base, several limiting grooves are opened inside the limiting disc, and the limiting grooves are rectangular. A first rotating disc is rotatably connected to the upper end surface of the limiting disc, and a meshing gear ring is fixedly connected to the outer wall of the first rotating disc.

[0010] As a further improvement of this solution, a second driving motor is fixedly installed at the bottom of the mounting base, the output end of the second driving motor is fixedly connected with a gear, the gear meshes with the meshing gear ring, several arc-shaped grooves are opened inside the first rotating disc, and a sliding rod is slidably connected between the inner walls of the limiting groove and the arc-shaped groove. A fixing cylindrical block is fixedly connected to the upper end surface of the sliding rod.

[0011] As a further improvement of this solution, the polishing mechanism includes a rotating rod and a recycling rod. The rotating rod and the recycling rod are both rotatably connected to the bottom of the fixing disc. The outer wall of the rotating rod is wound with abrasive paper, and one end of the abrasive paper away from the rotating rod is fixedly connected to the recycling rod. A third rotating disc is rotatably connected to the bottom of the fixing disc, one end of the third rotating disc close to the rotating rod is fixedly connected to the rotating rod, two limiting arc-shaped blocks are rotatably connected inside the third rotating disc, and the two limiting arc-shaped blocks are fixedly connected to the abrasive paper. A fixing cover is rotatably connected to the end of the third rotating disc away from the rotating rod, and the fixing cover is fixedly connected to the fixing disc.

[0012] As a further improvement of this solution, a reset torsion spring is installed at the end of the fixing cover close to the third rotating disc, and the reset torsion spring is clamped between the two limiting arc-shaped blocks. A second rotating disc is fixedly connected to the outer wall of the recycling rod, several elastic telescopic arms are fixedly connected inside the second rotating disc, and an abutting tooth block is fixedly connected to the output end of the elastic telescopic arm. An elastic telescopic rod with a reset function is fixedly connected to the bottom of the fixing disc.

[0013] Further, at the bottom end of the inner wall of the elastic telescopic rod, a connecting rod is fixedly connected, and at the bottom of the elastic telescopic rod, a clamping tooth block is fixedly connected. The outer wall of the clamping tooth block abuts against a corresponding set of abutting tooth blocks. Lubricating oil is applied to the outer surfaces of the clamping tooth block and the abutting tooth block, which can reduce the friction between the abutting tooth block and the clamping tooth block.

[0014] Beneficial effects

[0015] The utility model provides a small part polishing device. Compared with the prior art, it has the following beneficial effects:

[0016] For this small part polishing device, by rotating the second rotating disc at this time, the second rotating disc drives the abutting tooth block to rotate through the elastic telescopic arm. When the abutting tooth block abuts against the clamping tooth block, the elastic telescopic arm will contract, and the second rotating disc will also drive the recovery rod to rotate. The recovery rod pulls the abrasive paper to wind around the outer surface of the recovery rod. The handle mounting base drives the rotating rod to rotate, and the rotating rod drives the reset torsion spring to rotate and store energy through two groups of limiting arc blocks. At this time, the abrasive paper is in a taut state, which can better abut against the outer wall of the part, and the replacement of the abrasive paper is completed. Description of the drawings
