Problems solved by technology
[0002] In order to realize the flying pendulum function, when the rotating spindle drives the tool seat to rotate, the frictional resistance between the tool seat and the guide rail is large, resulting in high power consumption; and because the inertia of the tool seat is relatively large during rotation, the tool seat rotates The positioning is not accurate enough, which will affect the cutting quality of the product

Embodiment Construction
[0014] The anti-backlash floating mechanism of the flying pendulum scissors seat includes the rotating main shaft 1 connected with the tool seat. The upper end of the rotating main shaft 1 is internally connected in the main shaft sleeve 2, and the lower end of the main shaft sleeve 2 is internally connected with a double-row cylindrical roller bearing 3 on the rotating main shaft 1. The lower end of the double-row cylindrical roller bearing 3 is provided with a lower end cover 4, which is set on the rotating main shaft 1 and connected with the lower end surface of the main shaft sleeve 2 through a screw 5. The upper end of the rotating main shaft 1 is covered with a spacer 6 on the first stepped shaft, and the main shaft sleeve 2 The upper end surface is provided with an upper end cover 7 and is connected with it by screws 5. The lower end surface of the upper end cover 7 is provided with a boss located in the aperture of the main shaft sleeve 2. The lower end surface of the bo...

The invention relates to a pendulum tool apron gap eliminating floating mechanism. The pendulum tool apron gap eliminating floating mechanism comprises a rotation shaft connected with a tool apron; the upper end of the rotation shaft is sleeved with a shaft sleeve; a biserial cylindrical roller bearing is sleeved with the lower end of the shaft sleeve and is on the rotation shaft; a first stepped shaft on the rotation shaft is sleeved with a sleeve I; an upper end cover is arranged on the upper end surface of the shaft sleeve and is connected with the upper end surface of the shaft sleeve through screws; a boss is arranged on the lower end surface of the upper end cover and is located inside the shaft sleeve aperture; a plurality of counter bored holes are formed in the lower end surface of the boss; a disk spring I is arranged in each counter bored hole; a sliding block I penetrates the inner diameter of each disk spring I; a radial boss is arranged at the lower end of each sliding block I to seal the disk spring I inside each counter bored hole; a pin I penetrates each sliding block I and is connected with the upper end cover; and the tail end of each pin I is located inside the lower end surface of each sliding block I. The pendulum tool apron gap eliminating floating mechanism has a simple structure; when the rotation shaft drives the tool apron to rotate, the retractable function of the disk springs is adopted, a certain gap exists between the tool apron and a guide rail, the friction between the tool apron and the guide rail can be eliminated, so that the fast swing of the pendulum can be achieved, and the positioning is more accurate.
Description
technical field [0001] The invention relates to a backlash-eliminating floating mechanism of a flying pendulum scissors seat, and belongs to the technical field of flying pendulum shearing machinery and equipment. Background technique [0002] In order to realize the flying pendulum function, when the rotating spindle drives the tool seat to rotate, the frictional resistance between the tool seat and the guide rail is large, resulting in high power consumption; and because the inertia of the tool seat is relatively large during rotation, the tool seat rotates The positioning is not accurate enough, which will affect the cutting quality of the product. Contents of the invention [0003] In view of the above defects, the object of the present invention is to provide a backlash-eliminating floating mechanism for the flying pendulum scissors base with simple structure, eliminating the friction between the knife base and the guide rail, realizing fast flying pendulum shears, an...
