Description

Technical Field

[0001] The invention relates to a slider device running on a curved guide rail. Background Art

[0002] The commonly used guide rails with double sides as guide surfaces and the matching sliders generally have four rollers installed on the base mounting plate of the slider, and the axis positions of these four rollers are fixed. Such a slider is feasible if it only moves on a linear guide rail or only moves on a circular guide rail. However, it is not feasible for such a slider with a fixed roller axis to move on a curved guide rail composed of a linear guide rail and a circular guide rail of arbitrary curvature. It can be known from geometry that a slider with a fixed roller axis that satisfies the requirement of moving on a linear guide rail cannot move on a circular guide rail (such as Figure 1 ). Accordingly, a slider with a fixed roller axis that moves on an annular guide rail cannot move on a linear guide rail (such as Figure 2 ). If the S-shaped curved guide rail is composed of multiple sections of annular guide rails of arbitrary arcs connected end to end, the sliders on the annular guide rails of different arc sections cannot be used universally.

[0003] If the four roller axes on the slider are not fixed, and are divided into two front and rear roller groups, and each roller group rotates around its own center (the midpoint of the line connecting the two roller axes), although when the slider moves on the linear guide, its center is on the center line of the guide. However, when the slider moves to the circular guide, its center will deviate from the center line of the circular guide and shift a certain distance toward the center of the circular guide (such as Figure 3 ).

[0004] If the motion trajectory of the center point of the slider with a fixed roller axis is to be made to coincide with the center line of the guide rail, the commonly used approach is to adjust the cross-sectional dimensions of the curved and straight sections of the guide rail, which in turn requires additional processing of the guide rail. Summary of the invention

In order to reduce the friction between the upper and lower surfaces of the front and rear mounting plates and the lower surface of the upper cover and the upper surface of the bottom plate respectively when the front and rear roller groups move relative to the box seat, and to bear the load of the box seat on the upper and lower planes of the front and rear mounting plates, front annular grooves are respectively opened at the top surface of the top wall and the bottom surface of the bottom wall of the front mounting plate at the positions corresponding to the shaft rod, and a front plane bearing 23 coaxial with the shaft rod is embedded in each front annular groove, and a rear annular groove is respectively opened at the top surface of the top wall and the bottom surface of the bottom wall of the rear mounting plate at the positions corresponding to the shaft rod, and a rear plane bearing 23 coaxial with the shaft rod is embedded in each rear annular groove. In the present invention, during installation, the center of the box seat is overlapped with the center of the main roller group, so as to ensure that when the slider device moves on the guide rail, the center of the slider device is on the center line of the guide rail at any position.

[0046] Each bearing roller shown in the embodiment of the present invention is a bearing roller with a V-shaped groove, and the corresponding guide rail 1 is a guide rail with V-shaped edges on both sides, a V-shaped edge guide rail 11 with a rack on one side, and a V-shaped edge guide rail 12 with racks on both sides. The motion trajectory of the center point of the slider coincides with the center line of the guide rail, and the center line of the guide rail refers to the center line of the length direction of the guide rail, which is very important for the assembly of materials on the actual production line.

[0047] The two rollers on the main roller group or the slave roller group clamp the guide rail and roll on the guide rail. The axis position of the bearing roller on the mounting plate is fixed. The midpoint of the axis line of the two bearing rollers on the roller group, i.e., the connecting axis of the roller group, is on the center line of the guide rail. For the main roller group or the slave roller group, the connecting line of the bearing roller axes on it is always perpendicular to the center line of the guide rail, that is, for the roller group on the circular guide rail, the connecting line of the roller axes passes through the center of the guide rail; for the roller group on the linear guide rail, the connecting line of the bearing roller axes is perpendicular to the center line of the guide rail. The main and slave roller groups are placed in front and behind the main roller group and have a certain distance from the main roller group. In order to keep the connecting line of the roller axes perpendicular to the center line of the guide rail and keep the distance from the main roller group unchanged, it is necessary to rotate a certain angle relative to the rotating shaft of the main roller group. Therefore, the fixed length connecting rod used to connect the main roller group and the slave roller group must rotate relative to the connecting axis of the main roller group and the connecting axis of the slave roller group.

[0048] A gear 71 is coaxially mounted on the bearing roller on either side of the main roller assembly. Fig.12 and Fig.13As shown, a gear 71 is installed below the right bearing roller of the main roller assembly, and the gear is installed at the lower end of the shaft of the right bearing roller. A slewing bearing 71A is arranged between the shaft of the right bearing roller and the main mounting plate. The shaft of the right bearing roller is connected to the output shaft of the driving mechanism 81 to obtain the driving torque. Among them, for the gear 7 installed on the roller shaft to drive the slider, the roller shaft is installed in the hole of the main roller mounting plate through the slewing bearing, and can rotate independently in the hole of the main mounting plate. Such a slider device can move on the curved guide rail 11 with a rack on one side.

[0049] like Fig.14 and Fig.15 As shown, a gear 72 is coaxially installed below the left bearing roller and the right bearing roller of the main roller group, one of which is installed at the lower end of the shaft of the right bearing roller, and a right slewing bearing 72A is arranged between the shaft of the right bearing roller and the main mounting plate, and another gear is installed at the lower end of the shaft of the left bearing roller, and a left slewing bearing 72B is arranged between the shaft of the left bearing roller and the main mounting plate. The gear 72 is coaxial with the bearing roller and fixedly installed on the roller shaft, and is respectively connected to the output shaft of each driving mechanism 82 to obtain the driving torque. Among them, for the gear installed on the roller shaft to drive the slider, the roller shaft is installed in the hole of the main roller mounting plate through the slewing bearing, and can rotate independently in the hole of the main mounting plate. Such a slider device can move on the double-sided rack curve guide 12.

[0050] Commonly used curved guide rails are generally composed of a linear guide rail and an annular guide rail of any curvature connected end to end, or a plurality of annular guide rails of any curvature connected end to end. The present invention takes these two combinations of curved guide rails as examples: a curved straight guide rail ( Figures 19 to 21 , the motion principle of the curved guideway composed of a linear guide and a circular guideway); the S-shaped curved guideway composed of two arc circular guideways ( Figures 16 to 18 , the S-curve guide motion principle), describes the slider device that can move on it.
