[0002] Alignment platforms are important industrial devices widely used in various manufacturing and assembly fields, such as semiconductor packaging, electronics manufacturing, and medical device manufacturing. The working principle and characteristics of alignment platforms have a significant impact on their performance and effectiveness.

[0003] A search revealed that patent application number 2010105227475 discloses an alignment platform, including a platform with four support mechanisms arranged at the four corners of a rectangle beneath it. Each support mechanism consists of a support bearing with a cross guide rail pair underneath, the cross guide rail pair comprising an upper guide rail, a lower guide rail, and a middle slider. The upper end of the support bearing is fixedly connected to the platform, and its lower end is fixedly connected to the upper guide rail of the corresponding cross guide rail pair, while the lower guide rail of the cross guide rail pair is fixed to the mounting base. The rectangle has one pair of edges along the X-direction and another pair along the Y-direction. The lower guide rails of the cross guide rail pairs located at both ends of one Y-direction edge of the rectangle are arranged along the X-direction, and each of these two cross guide rail pairs has an X-direction push-pull sliding mechanism acting on its middle slider. Another cross guide rail pair has its lower guide rail arranged along the Y-direction, and this cross guide rail pair has a Y-direction push-pull sliding mechanism acting on its middle slider. This alignment platform is easy to control, ensures mechanical precision, and has a compact structure.

[0004] When the aforementioned patent is used, a servo motor drives the lead screw to rotate, thereby moving the table. However, the rotation of the lead screw will cause a jerking sensation on the table, which will directly affect the accuracy of the table during alignment. Summary of the Invention

[0005] The purpose of this invention is to propose an embedded cross ball bearing guide alignment platform to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows: an embedded cross ball bearing guide alignment platform is provided, comprising two sliding components, which are distributed vertically and horizontally, and a support box is fixedly installed on the outer wall of each of the two sliding components. A top plate is fixedly installed on the top of the upper sliding component, and a placement groove is fixedly connected to the top of the top plate. A support component is installed on the top of each of the two support boxes.

[0007] Furthermore, the sliding assembly includes a straight guide rail and a support block. The straight guide rail is located at the bottom of the sliding assembly, the support block is slidably mounted on the top of the straight guide rail, and the top plate is fixedly mounted on the support block above.

[0008] Furthermore, the outer wall of the straight guide rail is provided with circular grooves on both sides, and the support block has two annular movable grooves inside. Multiple steel balls are movably installed inside the annular movable grooves, and the steel balls are located between the circular grooves and the annular movable grooves.

[0009] Furthermore, the support assembly includes a mounting plate, a mounting shaft, and steel rollers. Two symmetrically distributed mounting plates are fixedly connected to the outer wall of the support box, and multiple linearly distributed mounting shafts are fixedly connected to the inner wall of the mounting plate. The steel rollers are movably mounted on the mounting shafts.

[0010] Furthermore, a baffle is fixedly connected to the front end of the mounting shaft, and a movable hole is provided inside the steel roller, which corresponds to the mounting shaft.

[0011] Furthermore, the outer wall of the bottom support box is fixedly connected with multiple rectangularly distributed fixing lugs.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] This utility model is equipped with a straight guide rail, a support block, a circular slide groove, an annular movable groove, and steel balls. When the support block slides on the top of the straight guide rail, the steel balls roll between the circular slide groove and the annular movable groove, which enables the support block to slide on the top of the straight guide rail. At the same time, the shape of the steel balls can reduce the contact area between the support block and the straight guide rail, thereby reducing the friction force generated by sliding.

[0014] This utility model includes a top plate, a support box, a mounting shaft, a mounting plate, and steel rollers. In use, the steel rollers are mounted on the top of the support box via the mounting shaft and the mounting plate. When the support box and the top plate move, the steel rollers provide support. At the same time, the shape of the steel rollers reduces the contact area between the support box and the top plate, thereby achieving the support function while reducing the friction generated when the support box and the top plate slide relative to each other, thus improving the accuracy of workpiece alignment.

[0025] Reference Figure 1-4This invention provides an embedded cross-ball bearing guide alignment platform. The platform includes two sliding components 1 arranged vertically in a cross configuration. Support boxes 7 are fixedly mounted on the outer walls of both sliding components 1. A top plate 8 is fixedly mounted on the top of the upper sliding component 1, and a placement groove 9 is fixedly connected to the top of the top plate 8. Support components are mounted on the tops of both support boxes 7. In use, the workpiece to be aligned is placed inside the placement groove 9. When the position of the workpiece needs to be adjusted, a pushing device is connected to the outer walls of the upper support box 7 and the top plate 8. The pushing device, in cooperation with the sliding components 1, moves the upper support box 7 and the top plate 8. When the upper support box 7 and the top plate 8 move, the support components provide support while reducing the contact area between the support box 7 and the top plate 8, preventing jerking during workpiece movement and thus improving the accuracy of workpiece alignment.

[0026] The sliding assembly 1 includes a straight guide rail 2 and a support block 3. The straight guide rail 2 is located at the bottom of the sliding assembly 1, and the support block 3 is slidably mounted on the top of the straight guide rail 2. The top plate 8 is fixedly mounted on the top support block 3. Since the top plate 8 is fixedly mounted on the upper support block 3, and the upper straight guide rail 2 is fixedly mounted on the lower support block 3, when the upper support box 7 and the top plate 8 are pushed, the support block 3 can slide on the top of the straight guide rail 2, thereby realizing the smooth sliding of the upper support box 7 and the top plate 8.

[0027] The outer wall of the straight guide rail 2 has circular grooves 4 on both sides, and the support block 3 has two annular movable grooves 5 inside. Multiple steel balls 6 are movably installed inside the annular movable grooves 5. The steel balls 6 are located between the circular grooves 4 and the annular movable grooves 5. When the support block 3 slides on the top of the straight guide rail 2, the steel balls 6 roll between the circular grooves 4 and the annular movable grooves 5, which realizes the sliding of the support block 3 on the top of the straight guide rail 2. At the same time, the shape of the steel balls 6 can reduce the contact area between the support block 3 and the straight guide rail 2, thereby reducing the friction force generated by sliding.

[0028] The support assembly includes a mounting plate 10, a mounting shaft 11, and steel rollers 13. Two symmetrically distributed mounting plates 10 are fixedly connected to the outer wall of the support box 7, and multiple linearly distributed mounting shafts 11 are fixedly connected to the inner wall of the mounting plate 10. The steel rollers 13 are movably mounted on the mounting shafts 11. In use, the steel rollers 13 provide support, and the shape of the steel rollers 13 can reduce the contact area between the support box 7 and the top plate 8, thereby achieving the support function while reducing the friction generated when the support box 7 and the top plate 8 slide relative to each other.

[0029] A baffle 12 is fixedly connected to the front end of the mounting shaft 11. The steel roller 13 has a movable hole 14 inside, which corresponds to the mounting shaft 11. In use, the steel roller 13 is installed inside the mounting shaft 11 through the movable hole 14, allowing it to rotate freely. By fixing the baffle 12 to the front end of the mounting shaft 11, the position of the steel roller 13 can be prevented from shifting when it rolls, thus preventing deviations in workpiece alignment.

[0030] The outer wall of the bottom support box 7 is fixedly connected with multiple rectangularly distributed fixing ear plates 15. In use, the support box 7 below can be fixed in the designated installation position by fixing the ear plates 15.

[0031] Working principle: First, the lower support box 7 is fixed in the designated installation position by fixing the ear plate 15. A pushing device is installed on the outer wall of the upper support box 7 and the top plate 8. Then, the workpiece to be aligned is placed inside the placement groove 9. When the position of the workpiece needs to be adjusted, the pushing device is activated. At the same time, the steel balls 6 roll between the circular slide groove 4 and the annular movable groove 5, so that the upper support box 7 and the top plate 8 can move smoothly. The shape of the steel balls 6 can reduce the contact area between the support block 3 and the straight guide rail 2, thereby reducing the friction generated when the support block 3 and the straight guide rail 2 slide relative to each other. When the upper support box 7 and the top plate 8 move, the steel rollers 13 can provide support. At the same time, the shape of the steel rollers 13 can reduce the contact area between the support block 3 and the straight guide rail 2, thereby further reducing the friction generated when the support block 3 and the straight guide rail 2 slide relative to each other. The reduced contact area can prevent the workpiece from jerking during movement, thereby improving the accuracy of workpiece alignment.

[0032] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
