Problems solved by technology
[0003] For the edge grinding devices for the production of lead-free tin bars currently on the market, there are still a lot of problems. The hand-held grinding device does not fix the effect well when grinding, and lead-free tin bars of different sizes need to be polished. The positions and angles are different, so we propose a corner grinding device for the production of lead-free tin bars in order to solve the above-mentioned problems

The invention discloses an edge and corner polishing device for lead-free tin bar production, and relates to the technical field of lead-free tin bar machining. A first sliding groove is formed in the lower surface of a supporting plate; a first motor is fixed to the right side wall of the first sliding groove and connected with an external power source; a first lead screw is fixed to an output shaft of the first motor, and the other end of the first lead screw is rotationally connected with the left side wall of the first sliding groove; the first lead screw is sleeved with a first nut in a screwed mode, and the first nut is movably clamped in the first sliding groove; an electric telescopic rod is fixed to the bottom of the first nut and connected with an external power source; a first connecting plate is arranged at the movable end of the electric telescopic rod; and a box body is arranged below the first connecting plate. Adjustment can be carried out according to the height and angle of the lead-free tin bar, and practicability is improved; fixing can be conducted according to the size of the lead-free tin bar, and movement of the lead-free tin bar is not affected; and the service life of the polishing device is prolonged.
Description
technical field [0001] The invention relates to the technical field of lead-free tin bar processing, in particular to an edge grinding device for lead-free tin bar production. Background technique [0002] Lead-free tin bar is one of the important materials for soldering in electronic assembly. Due to its excellent performance and non-toxicity, it is highly valued in the field of electronic welding. When producing lead-free tin bar, after it comes out of the mold, its edges and corners are sharp and easy When in use, it pricks the user's hand, so its edges and corners need to be smoothed. [0003] For the edge grinding devices for the production of lead-free tin bars currently on the market, there are still a lot of problems. The hand-held grinding device does not fix the effect well when grinding, and lead-free tin bars of different sizes need to be polished. The positions and angles are different, so we propose a corner grinding device for the production of lead-free tin ...
