Description

Technical Field

[0001] This utility model relates to the field of transmission, and in particular to the field of high-precision and high-durability transmission technology, specifically a large-stroke high-precision slide table. Background Technology

[0002] In fields such as precision machining, industrial inspection, and automated assembly, the XY-direction slide table is a core component for achieving precise displacement adjustment of workpieces or equipment, and its performance directly affects the accuracy, stability, and reliability of the entire production or inspection system.

[0003] The existing slide table structure is complex and redundant, which not only increases manufacturing costs but also brings many inconveniences to subsequent maintenance. To achieve multi-directional adjustment, some slide tables incorporate too many intermediate components such as transmission gears and connecting shafts. The assembly relationships between these components are cumbersome, increasing the difficulty of parts processing and assembly, leading to a significant increase in manufacturing costs and a higher probability of malfunctions. Furthermore, the complex structure makes it difficult for maintenance personnel to quickly locate the fault when a slide table fails, resulting in time-consuming and labor-intensive maintenance processes, significantly increasing maintenance costs, hindering the long-term stable operation of the equipment, and reducing the company's production efficiency.

[0037] The purpose of this invention is to provide a slide table in the XY direction, which aims to solve the problems of low precision, insufficient load-bearing capacity, complex structure and poor protection performance of existing slide tables, so as to meet the needs of different fields for high precision, high stability and high reliability slide tables.

[0038] In general, the large-stroke high-precision slide table proposed in this utility model mainly includes: a transmission module base 1, a Y-axis transmission base 2, a transmission module 3, and a drive module 4. (See also...) Figure 1 It shows the arrangement of the transmission module base 1, the Y-axis transmission base 2, the transmission module 3 and the drive module 4.

[0039] When the large-stroke high-precision slide table proposed in this utility model is used, the drive module 4 at the top of the transmission module base 1 controls the slide table 34 to move back and forth along the X-axis, and the drive module 4 at the top of the Y-axis transmission base 2 controls the slide table 34 to move back and forth along the Y-axis. Specifically, the motor 41 controls the rotation of the rotating shaft, which in turn causes the ball screw 43 to rotate through the coupling 42. The rotation of the ball screw 43 controls the drive slider 47 to drive the Y-axis transmission base 2 or the slide table 34 to move back and forth along the ball guide rail 32.

[0040] The Y-axis transmission base 2 is positioned directly above the transmission module base 1. The transmission module base 1 and the Y-axis transmission base 2 are arranged in a cross shape, which allows the slide 34 to move along the X-axis and Y-axis.

[0041] The aforementioned transmission module 3 is bolted to the left and right sides of the top of the transmission module base 1 and the Y-axis transmission base 2. The transmission module 3 includes: a guide rail mounting and positioning block 31, a transmission slider 33, and a slide table 34. The guide rail mounting and positioning block 31 is bolted to the left and right sides of the top of the transmission module base 1 and the Y-axis transmission base 2. The guide rail mounting and positioning block 31 is bolted to a ball guide rail 32, which has high movement accuracy. The transmission slider 33 is mounted on the ball guide rail 32. The top of the transmission slider 33, which is mounted on one side of the transmission module base 1, is bolted to the Y-axis transmission base 2, so that the Y-axis transmission base 2 can be driven by the drive slider 47 to move along the X-axis. The top of the transmission slider 33, which is mounted on one side of the Y-axis transmission base 2, is bolted to a slide table 34, so that the slide table 34 can be driven by the drive slider 47 to move along the Y-axis.

[0042] The aforementioned drive module 4 is bolted to the center of the top of the transmission module base 1 and the Y-axis transmission base 2. The drive module 4 includes: a motor 41, a coupling 42, a ball screw 43, a double-row angular contact bearing 46, a drive slider 47, a bearing cover plate 48, a bushing 49, and a retaining ring 410. The motor 41 is bolted to the center of one side of the top of the transmission module base 1 and the Y-axis transmission base 2. A rotating shaft passes through the center of the motor 41, and the coupling 42 is sleeved on the outside of the rotating shaft. The coupling 42 is located on the side away from the rotating shaft. The device is equipped with a ball screw 43. Specifically, the ball screw 43 is connected to the motor 41 via a coupling 42. Bearing seats 44 and limit blocks 45 are sequentially fitted on the left and right sides of the ball screw 43. A double-row angular contact bearing 46 passes through the center of the bearing seat 44 and is fitted onto the outer side of the ball screw 43. A drive slider 47 is fitted onto the outer side of the ball screw 43, located between the limit blocks 45 on both the left and right sides of the ball screw 43. It should be noted that the bearing seat 44 controls the rotation of the ball screw 43. To ensure stability, the limit stop 45 controls the distance the drive slider 47 moves on the ball screw 43, preventing the drive slider 47 from derailing. The top of the drive slider 47, mounted on one side of the guide rail mounting positioning block 31, is connected to the Y-axis transmission base 2 by bolts, allowing the Y-axis transmission base 2 to be moved along the X-axis by the drive slider 47. The top of the drive slider 47, mounted on one side of the Y-axis transmission base 2, is connected to the slide table 34 by bolts, allowing the slide table 34 to be moved along the Y-axis by the drive slider 47. (The last sentence appears to be incomplete and possibly refers to a different topic.) A bearing cover plate 48 is fitted between the bearing housing 44 and the coupling 42. The bearing cover plate 48 is connected to the bearing housing 44 by bolts. A bushing 49 is fitted on the outside of the ball screw 43 and abuts against the bearing housing 44 and the bearing cover plate 48. It should be noted that the bushing 49 and the bearing cover plate 48 abut against and fill the space between the coupling 42 and the bearing housing 44 to improve the stability of the ball screw 43 during rotation. A retaining ring 410 is fitted on the side of the ball screw 43 away from the motor 41. The retaining ring 410 abuts against the double row angular contact bearing 46 on one side.

[0043] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
