[0022] The technical solutions in the embodiments of the utility model will be apparently and completely described in conjunction with the drawings of the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments of the utility model, all the other embodiments obtained by the person skilled in the art without any creative labor fall within the protection scope of the utility model.
[0023] Embodiment 1:
[0024] A linear bearing guide rail, as shown in Figure 1 and 2 , comprises a guide rail 1 and a bearing sliding block 2, the guide rail 1 is an elongated structure extending along direction X, two directions perpendicular to the direction X are direction Y and direction Z perpendicular to the direction Y respectively; that is, the direction X is the length direction of the guide rail, the direction Y is the width direction of the guide rail, and the direction Z is the height direction of the guide rail.
[0025] The cross section of the guide rail 1 is a symmetrical structure relative to the symmetry axis L. Here, the cross section is the cross section in the direction X, and the symmetrical structure processing only needs to be subjected to grinding treatment once, thereby simplifying the manufacturing process, improving the manufacturing efficiency, and also facilitating the assembly of the bearing sliding block and the guide rail.
[0026] As shown in Figure 2 and 5 , the guide rail 1 is sequentially provided with a head portion 11, a neck portion 12 and a bottom portion 13 in the height direction; the head portion 11 is the uppermost, and the bottom portion 13 is at the lowermost.
[0027] The maximum width of the head portion 11 in the width direction is a head width, the minimum width of the neck portion 12 in the width direction is a neck width, and the maximum width of the bottom portion 13 in the width direction is a bottom width. The neck width is smaller than the head width and the bottom width.
[0028] A first upper rail slope 111 and a first lower rail slope 112 are arranged at one side of the head width of the head portion 11. The first lower rail slope 112 is below the first upper rail slope 111, and the first upper rail slope 111 and the first lower rail slope 112 are oppositely inclined. The first upper rail slope 111 and the first lower rail slope 112 form an inclined angle of 90°. The connection between the first upper rail slope 111 and the first lower rail slope 112 is located at the head width, and the connection between the first upper rail slope 111 and the first lower rail slope 112 does not contact the first bearing.
[0029] A second upper rail slope 113 and a second lower rail slope 114 are arranged at the other side of the head width of the head portion 11. The second lower rail slope 114 is below the second upper rail slope 113, and the second upper rail slope 113 and the second lower rail slope 114 are oppositely inclined. The second upper rail slope 113 and the second lower rail slope 114 form an inclined angle of 90°. Since the guide rail 1 is symmetrical about the symmetry axis L, the first upper rail slope 111 and the second upper rail slope 113, and the first lower rail slope 112 and the second lower rail slope 114 are symmetrical about the symmetry axis L. Similarly, the connection between the second upper rail slope 113 and the second lower rail slope 114 does not contact the second bearing.
[0030] The guide rail only needs to undergo a transverse grinding process, and does not need a top grinding process or any other grinding process in other directions, thereby simplifying the manufacturing process and improving the manufacturing efficiency. In addition, the present application also solves the problem that the two grinding processes of the conventional bearing guide rail have different grinding references.
[0031] As shown in FIGS. Figure 2 , 3 and 4, the bearing slider 2 includes a slider plate 23, and a plurality of fixing shafts 24 are arranged on the lower end surface of the slider plate 23. Each fixing shaft 24 is provided with a bearing, and the bearing is threadedly connected to the fixing shaft 24 below the bearing by a locking nut, so as to limit the installation position of the bearing on the fixing shaft.
[0032] In the present application, the bearings include a first bearing 21 and a second bearing 22, and the first bearing and the second bearing have the same structure. The first bearing 21 and the second bearing 22 are in rolling contact with the head portion 11.
[0033] Specifically, the outer circumferential surface of the first bearing 21 is provided with a first upper bearing contact surface 211 and a first lower bearing contact surface 212, and the inclined angle formed by the first upper bearing contact surface 211 and the first lower bearing contact surface 212 is 90°; the first upper bearing contact surface 211 contacts the first upper track inclined surface 111, and the first lower bearing contact surface 212 contacts the first lower track inclined surface 112.
[0034] The outer circumferential surface of the second bearing 22 is provided with a second upper bearing contact surface 221 and a second lower bearing contact surface 222. The inclined angle formed by the second upper bearing contact surface 221 and the second lower bearing contact surface 222 is 90°. The second upper bearing contact surface 221 contacts the second upper track inclined surface 113, and the second lower bearing contact surface 222 contacts the second lower track inclined surface 114.
[0035] Because the first bearing and the second bearing can rotate relative to the fixed shaft along the guide rail, the first upper bearing contact surface 211, the first lower bearing contact surface 212, the second upper bearing contact surface 221, and the second lower bearing contact surface 222 are all closed end faces. When viewed from above along the axis, they are annular, and all are about the axis of the fixed shaft.
[0036] The first and second bearings are V-type bearings, which roll into contact with the two inclined surfaces of the guide rail head through the V-shaped surface, preventing powder from entering. The appropriate width of the neck can maintain the rigidity of the guide rail.
[0037] To prevent the bearing slider from sliding off the guide rail, baffles 6 are provided at both ends of the guide rail.
[0038] During assembly, the two bearing bearing surfaces of the first bearing contact with the two inclined surfaces of the guide rail head, and the two bearing bearing surfaces of the second bearing contact with the two inclined surfaces of the guide rail head, thus confining the slider plate to the guide rail and realizing the relative movement of the slider and the guide rail.
[0039] Example 2:
[0040] A track module for fire extinguisher manufacturing, such as Figure 6 , 7 As shown in Figure 8, the system includes a mounting base plate 3, a moving component 4, two linear bearing guide rails as described in Embodiment 1, and a base plate 5. The moving component 4 and the linear bearing guide rails are both mounted on the base plate 5, making the track module a whole. It can be moved and installed as a whole, and the reference planes of the linear bearing guide rails are the same.
[0041] The moving component 4 can be a telescopic cylinder, a motor screw and nut structure, or an electric cylinder, etc. Anything that can apply force along the X direction to the mounting base plate is acceptable.
[0042] The moving assembly 4 is arranged in parallel with the two linear bearing guides, and the movable part of the moving assembly is connected with the mounting base plate 3, the mounting base plate 3 is connected with the slider plate 23 of the linear bearing guide, and the upper end surface of the mounting base plate 3 serves as a functional module assembly position. The functional mechanism 7 is mounted on the upper end surface of the mounting base plate to provide movement guidance for the functional mechanism.
