Description
Technical Field
[0001] The utility model relates to a slide table, in particular to a ball slide table, and belongs to the technical field of slide tables. Background Art
[0002] Objects on the load-bearing platform are generally in flat contact. Due to the influence of friction, it is difficult for them to move freely on the load-bearing platform, especially the heavier the object.
[0003] From physical knowledge, we know that the magnitude of friction is proportional to the friction coefficient and the normal pressure. The rolling friction coefficient between objects is smaller than the sliding friction coefficient. After changing the sliding friction state between objects to the rolling friction state, the friction force between objects will be greatly reduced. The ball slide plays the role of converting the sliding friction state and the rolling friction state between objects. Utility Model Content

[0006] Preferably, guide posts are welded on the upper cover plate welding piece of the utility model, guide sleeves are welded on the bull's eye system, and the upper cover plate welding piece and the bull's eye system are connected via the guide posts and the guide sleeves.
[0007] Preferably, the upper cover plate welding of the utility model is provided with a plurality of holes, a plurality of bull's eye bearings are arranged on the bull's eye system, and the positions and numbers of the plurality of holes correspond one to one with the positions and numbers of the bull's eyes on the plurality of bull's eye bearings; when the bull's eye system moves up and down, the bull's eye bearings will pass through the holes of the upper cover plate welding part without interfering with each other.
[0008] Preferably, the bull's eye bearing of the utility model comprises matching large steel balls and small steel balls.
[0009] Preferably, the upper cover plate welding part of the utility model is connected to the bottom plate welding part through a guide column.
[0010] Preferably, the push plate system of the utility model is further provided with a lower roller cooperating with the upper roller.
[0011] Compared with the prior art, the utility model has the following advantages and effects: the overall structural design is simple and reasonable, safe and reliable, and the ball slide can convert the sliding friction state and the rolling friction state between objects; since the number of bull's eye bearings is large and the distribution is dense, the bottom surface of the heavy object is in contact with multiple bull's eye bearings, and the rolling resistance of the large steel balls of the bull's eye bearings is small, so the heavy object can be moved horizontally relatively easily.

DETAILED DESCRIPTION
[0018] The present invention will be further described in detail below with reference to the accompanying drawings and through examples. The following examples are provided to explain the present invention, but the present invention is not limited to the following examples.
[0019] Example
[0020] See also Figures 1 to 5 In this embodiment, the bottom plate welding part 2 is connected to the push plate system 3 through the oil cylinder 1, the bull's eye system 4 is welded with a guide sleeve 41 and an inclined raceway 42, and the upper cover plate welding part 5 is welded with a guide column 51. The bull's eye system 4 is connected to the upper cover plate welding part 5 through the guide column 51 and the guide sleeve 41, and the upper cover plate welding part 5 is connected to the bottom plate welding part 2 through the guide column 51, and the guide roller 44 cooperates with the corresponding guide column 51.
[0021] The push plate system 3 in this embodiment is provided with an upper roller 31 and a lower roller 32 , and the upper roller 31 is in contact with the inclined surface raceway 42 of the bull's eye system 4 .
[0022] The interior of the bull's eye bearing 43 is composed of a large steel ball 431 and a small steel ball 432, which is a rolling structure. The friction force of the large steel ball 431 when rolling is relatively small. Figure 2 shown.
[0023] The push plate system 3 in this embodiment can move horizontally on the bottom plate welding part 2 under the push of the piston rod of the cylinder 1, and the upper roller 31 of the push plate system 3 generates pressure on the inclined raceway 42 of the bull's eye system 4. This pressure will be decomposed into horizontal and vertical components. Due to the limiting effect of the guide column 51 and the guide sleeve 41, the bull's eye system 4 can only move up and down along the guide column 51.
[0024] The upper cover plate welding part 5 in this embodiment is provided with a plurality of holes 52, and the positions and number of the plurality of holes 52 correspond one to one with the positions and number of the bull's eyes of the plurality of bull's eye bearings 43 on the bull's eye system 4, so when the bull's eye system 4 moves up and down, the bull's eye bearings 43 will pass through the holes of the upper cover plate welding part 5 without interfering.
[0025] When the piston of the oil cylinder 1 extends, the bull's eye system 4 rises, and the highest point of the large steel ball 431 of the bull's eye bearing 43 is higher than the upper plane of the upper cover plate welding part 5. Since the number of bull's eye bearings 43 is large and the distribution is dense, the bottom surface of the heavy object is in contact with multiple bull's eye bearings 43, and the rolling resistance of the large steel ball 431 of the bull's eye bearing 43 is small, so the heavy object can be moved horizontally relatively easily. Figure 4 shown.
[0026] When the piston of the oil cylinder 1 retracts, the bull's eye system 4 descends, and the highest point of the large steel ball 431 of the bull's eye bearing 43 is lower than the upper plane of the upper cover plate weldment 5. The bottom surface of the weight is in contact with the upper plane of the upper cover plate weldment 5. Due to the large sliding resistance of the contact surface, the weight stays stably on the upper cover plate weldment 5. See Figure 5 shown.
[0027] Through the above description, those skilled in the art can already implement it.
[0028] In addition, it should be noted that the shapes and names of the parts and components of the specific embodiments described in this specification may be different, and the above content described in this specification is only an example of the structure of the utility model. All equivalent changes or simple changes made based on the structure, features and principles described in the patent concept of the utility model are included in the protection scope of the utility model patent.
