Background technique

Grinding is a kind of surface modification technology. It generally refers to a processing method that uses rough objects (such as: sandpaper containing higher hardness particles, etc.) to change the physical properties of the material surface through friction. The main purpose is to obtain a specific surface roughness. Spend. Mechanical grinding is mainly to remove the burr on the surface of the product workpiece, make it smooth, easy to continue processing or reach the finished product. There are many types of mechanical grinding tools commonly used, which can be divided into two categories: pneumatic grinding tools and electric grinding tools according to different power devices. These When traditional grinding tools are used for grinding, more dust and waste residues are generated, causing greater pollution. The flying debris generated during the grinding process not only easily pollutes the surrounding environment, but also due to the small size of the flying debris, the cleaning process after production is very difficult. In addition, the existing mechanical grinding device has poor mobility and needs to be moved by a forklift or a crane, especially for grinding a large workpiece, and it is inconvenient to move the workpiece, it can only be realized by moving the grinding device, and the work efficiency is particularly low at this time .

detailed description

It should be noted that, in the case of no conflict, the embodiments of the present invention and the features in the embodiments can be combined with each other.

Specific embodiments of the invention will be described in detail below in conjunction with the accompanying drawings.

A mechanical grinding device, as shown in Figure 1, comprises a base 1, a frame 2 arranged on the base 1, and a rotating shaft 3 and a beam 4 arranged on the frame 2; the detachable coaxial Several grinding heads 5 are provided, and a dust collection cover 6 is provided on the position corresponding to the grinding head 5 on the cross beam 4, and a suction nozzle 7 is arranged in the dust collection cover 6; the suction nozzle 7 passes through a hose 8 It is connected with the dust collection box 9 on the base 1; the bottom end of the base 1 is provided with traveling wheels 10, and a counterweight 11 is provided on the base 1. A counterweight is arranged on the base to balance the weight of the structural parts such as the beam, the rotating shaft and the grinding head, so as to ensure that the center of gravity of the device is in the middle of the base, so that the structural stability of the entire grinding device is good.

Wherein, the dust suction nozzle 7 is arranged at the center of the dust collection hood 6 , and the outer edge of the dust collection hood 6 is provided with an obliquely downward eaves 12 . The use of the eaves 12 can efficiently gather smoke and dust, so that debris generated during the grinding process can be absorbed, so as to avoid polluting the environment and not affecting the health of operators.
