Problems solved by technology

[0010] However, the problems with the use of the adjustable guard are: ① the adjustable guard is very cumbersome to use in practice, because it must be adjusted anytime and anywhere along with the grinding of the grinding wheel; The gap must be less than 6 mm ( Figure 13 )” (Article 2.4.13 of GB4674-84)
[0012] (3) Traditional grinder guards do not conform to ergonomics
At this time, the operator has to adjust the posture, such as bending over, leaning back, etc., which is tiring enough

Embodiment Construction

[0042] Since the implementation forms of the barrier position adjustment and fixing mechanism can be various, the specific implementation modes of the present invention are also various. For the convenience of description, this section will be described in the following order:

[0043] A. Vertical and horizontal adjustment methods;

[0044] B. A solution using vertical and horizontal adjustment methods;

[0045] C. Radial and tangential direction adjustment methods;

[0046] D. Overall structure.

[0047] A. Vertical and horizontal direction adjustment implementation

[0048] In this embodiment, the barrier position adjustment mechanism is composed of a longitudinal position adjustment and fixing mechanism and a horizontal position adjustment and fixing mechanism.

[0049] Figure 5 —— 8 shows a specific example of this embodiment, in which the longitudinal position adjustment mechanism and the horizontal position adjustment mechanism are both gear-rack transmission mechan...

Abstract

The novel anti-explosion grinder has guard unit set on the protecting hood. The guard unit includes one adjustable barrier and one barrier position regulating mechanism. The grinder with said guard unit has the features of being safe and reliable except excellent operation performance. In case of damage grinding wheel, the present invention can block the grinding wheel fragment from injuring operator. In addition, the novel anti-explosion grinder coincides somatology and can improve labor environment, reduce dust pollution and lower labor strength.

Description

(1) Technical field [0001] The invention relates to a grinding machine—a grinder, in particular to a grinder protective cover. (2) Background technology [0002] Grinding is an important processing procedure in the machinery industry, and the grinder is an important type of grinding machinery. It uses a grinding wheel to process the workpiece. A grinding wheel is a porous object composed of abrasives and bonds. Abrasives have high hardness. During grinding, the abrasive particles on the surface of the high-speed rotating grinding wheel will grind the workpiece, and at the same time, they will be worn off, and the diameter of the grinding wheel will gradually become smaller. When the diameter of the grinding wheel is small to a certain extent, the grinding wheel needs to be replaced. up. In the case of continuous normal operation of the grinder, one shift consumes about 2-3 grinding wheels. [0003] Because the grinding wheel is brittle and fragile, the grinding wheel is ...
