Description

TECHNICAL FIELD

[0001] The utility model relates to guide rail sliding block equipment technical field especially, relates to a guide rail sliding block mounting mechanism. BACKGROUND

[0002] In mechatronic equipment, the guide rail and the sliding block pair mechanism are commonly used for guiding and limiting in linear motion mechanism. The guide rail sliding block mechanism of this type has the characteristics of high dimensional accuracy, high positioning accuracy and strong load capacity, and is widely used in various industrial, scientific research and equipment fields. However, it has the disadvantage of high installation requirement, and has high requirements for the levelness, rigidity of the installation surface and the rigidity of the load itself. Because the guide rail sliding block relies on the rolling body or the sliding body for limiting and guiding, the movement gap is usually micron level, and even the precision of the lowest guide rail sliding block is in the order of 0.1 mm. In actual production activities, in some occasions with very low precision requirement or even no requirement, it is also desired to use such guide rail sliding blocks (to utilize the characteristics of large load and smoothness). In these application scenarios, the installation surface is usually rough and has poor rigidity, and the load itself also does not have appropriate rigidity, such as large sliding doors and sliding covers. In such scenarios, the precision guide rail sliding block mechanism may be stuck due to deformation when in use (especially when used in pairs), resulting in failure of the mechanism.

[0003] In the prior art, the precision guide rail sliding block is often abandoned due to the risk of sticking, and a non-standard self-made linear walking mechanism is used instead. The non-standard linear mechanism has the disadvantages of poor reliability, weak universality, and the need for separate assembly and debugging, which is time-consuming. In other application scenarios, even if the precision guide rail sliding block is used, some measures can only be taken from the perspective of strengthening the rigidity of the installation mechanism and the rigidity of the load itself to reduce the risk of sticking. This treatment method not only increases the redundant design and brings the increase of design and production cost, but also cannot completely eliminate the risk.

[0004] Therefore, it is necessary to develop a guide rail sliding block mounting mechanism to solve the above problems. UTILITY MODEL CONTENTS

[0035] like Figures 1-6 As shown, a guide rail slider mounting mechanism includes:

[0036] Guide rail 2; Guide rail 2 fixed position setting;

[0037] Slider 3; Slider 3 is mounted on guide rail 2 and slides in cooperation with guide rail 2;

[0038] Adapter plate 4; Adapter plate 4 is mounted on slider 3, and the middle side wall of adapter plate 4 is formed as an outwardly convex annular spherical surface 9;

[0039] Load plate 5; The load plate 5 is provided with mounting holes, the adapter plate 4 passes through the mounting holes, and the outwardly protruding annular spherical surface 9 contacts the bottom of the mounting hole of the load plate 5.

[0040] In some embodiments, such as Figures 1-6As shown, the guide rail slider mounting mechanism further comprises a buffer rubber pad 6 and a baffle plate 7, the baffle plate 7 is installed on the top of the load plate 5, the buffer rubber pad 6 is formed into a ring shape, the buffer rubber pad 6 is sleeved on the upper side wall of the adapter plate 4, the lower end of the buffer rubber pad 6 is in contact with the load plate 5, and the lower end of the buffer rubber pad 6 is in contact with the baffle plate 7. The fixing of the adapter plate 4 on the load plate 5 relies on the clamping and limiting of the load plate 5 by the buffer rubber pad 6 and the baffle plate 7. The rubber pad 6 is clamped between the load plate 5 and the baffle plate 7, so that the baffle plate 7 can press the load plate 5 and the deformation amount under a certain load.

[0041] In some embodiments, as shown in Figure 6 As shown, the baffle plate 7 is connected with the adapter plate 4 by bolts.

[0042] In some embodiments, the mounting hole is a circular hole.

[0043] In some embodiments, as shown in Figure 2 As shown, the lower part of the outer convex annular spherical surface 9 has a diameter larger than that of the mounting hole, the upper part of the outer convex annular spherical surface 9 has a diameter smaller than that of the mounting hole, and the outer diameter of the buffer rubber pad 6 is larger than that of the mounting hole.

[0044] In some embodiments, as shown in Figure 5 As shown, an inner concave annular spherical surface is formed on the bottom of the load plate 5 and below the mounting hole, the outer convex annular spherical surface 9 has the same diameter as the inner concave annular spherical surface, and the outer convex annular spherical surface 9 and the inner concave annular spherical surface form a spherical surface fit.

[0045] As shown in Figure 1 and 2 In this application, the guide rail 2 is fixedly installed on the base 1, the connection between the load plate 5 and the adapter plate 4 adopts a spherical surface contact scheme, which can adapt to the relative displacement of the two in each direction; the fixing of the adapter plate 4 on the load plate 5 is realized by means of the buffer rubber pad 6 and the baffle plate 7; the baffle plate 7 is screwed and fastened with the end of the adapter plate 4; the rubber pad 6 is clamped between the load plate 5 and the baffle plate 7, so that the baffle plate 7 can press the load plate 5, and at the same time, the baffle plate 7 can also deform under a certain deformation load to adapt to the deformation.

[0046] As shown in Figure 3 As shown, the simulated load plate 5 bears an eccentric load, generates displacement or deformation, and causes left and right tilting, as shown in Figure 4 As shown, the top view direction is twisted, at this time, due to the unbalanced load on the load plate 5, a movement tendency is generated, on the one hand, the buffer rubber pad 6 and the baffle plate 7 limit the position, a small amount of displacement caused by the compression of the buffer rubber pad 6 is generated in the vertical direction and the eccentric load direction of the front view, at the same time, due to the spherical surface of the contact surface between the adapter plate 4 and the load plate 5, the relative rolling of the two occurs, in reality, the eccentric load is absorbed by the deformation of the load plate 5 and the load thereon, and will not be transmitted to the guide rail 2 and the slider 3, so as not to cause sliding jamming.

Figure 7 In the diagram, a guide rail slider mounting mechanism is installed at three locations: left, center, and right. In this case, the sliding cover 8 is connected and secured to the load plate 5 as a load. If an offset load occurs on the sliding cover 8, such as when a person stands on the sliding cover 8, the person's weight will be unevenly distributed on the sliding cover 8, causing the sliding cover 8 and the load plate 5 to deflect. This deformation will be absorbed by the spherical contact pair between the adapter plate 4 and the load plate 5, and will not be transmitted to the guide rail 2 and the slider 3, thus preventing sliding jamming.

[0048] The above are merely preferred embodiments of this utility model. It should be noted that, for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
