Description

Technical Field

[0001] The utility model relates to the field of elevator parts processing, in particular to an elevator sill fixing device. Background Art

[0002] The elevator sill is an important part of the elevator. It is located between the elevator car entrance and the floor entrance, and serves to connect the car and the floor. At present, elevators are used more and more, and the demand for elevator sills is also increasing. The requirements for elevator sill processing are also getting higher and higher. When the elevator sill profile is too long, it needs to be cut. It is necessary to fix it in advance for cutting. However, the current sill fixing device often causes the sill to slip during cutting due to unstable fixation. If the fixation is unstable and moves, it affects the cutting accuracy of the sill, which brings a lot of trouble to the subsequent work. In addition, a large amount of debris and dust often accumulates in the cutting avoidance groove, which affects the cutting effect and is difficult to clean. Utility Model Content

After clamping, the elevator sill profile is very stable and not easy to move; in the third step, the first fixing member and the second fixing assembly avoid the middle cutting area at the same time, so as to facilitate the operation of the cutting device; in the fourth step, during the cutting process, a large amount of fragments and dust will be generated and fall into the cutting avoidance groove at the lower end, and the dust will be absorbed and removed in time by the cleaning assembly. At the same time, the suction force generated also has a certain effect of suppressing the flying of cutting waste, and the fragments are pushed by the cleaning assembly moving left and right, and the fragments are automatically discharged from the left and right ends of the cutting avoidance groove; in the fifth step, after the cutting is completed, the front and rear ends of the elevator sill profile can still be stably fixed and will not fall off. Compared with the traditional fixing device, which only uses one point to fix, it will automatically fall off after cutting to damage the elevator sill.

After clamping, the elevator sill profile is very stable and not easy to move. At the same time, after the cutting is completed, the front and rear ends of the elevator sill profile can still be stably fixed and will not automatically fall and cause damage to the elevator sill. By arranging a cleaning component and a cleaning component in the cutting avoidance groove, a large amount of fragments and dust falling into the cutting avoidance groove are processed, and the dust is absorbed and removed in time by the cleaning component.

[0024] In the second step, the controller starts the control cylinder 302 on the outside of the moving mounting plate 301. The piston rod of the control cylinder 302 pushes the linkage frame 303 to drive the two front-to-back symmetrical clamping plates 304 to move inward.
