Description

Technical Field

[0001] The present application relates to the technical field of sliding tables, and in particular to a moving sliding table. Background Art

[0002] A sliding table is a mechanical device that can achieve precise linear motion and has a wide range of application fields. In machining, it can be used for tool feeding of machine tools, workpiece positioning, etc.; in an automated production line, it realizes material handling, assembly, and detection; in the manufacture of electronic equipment, it assists in chip pasting, circuit board assembly, etc.; in medical equipment, it precisely controls the movement of instrument components for diagnosis and treatment.

[0003] A sliding table usually consists of a load platform, guide rails, sliders, a drive system, and an installation platform, etc. The guide rails provide guidance for the movement of the sliders to ensure the straightness and accuracy of their movement. The sliders carry the working components and slide smoothly along the guide rails, and the drive system is the power source for the movement of the sliding table.

[0004] Existing drive systems are mostly cylinders or hydraulic cylinders. However, in some application fields such as lathes, when machining, forces will be generated on the workpiece, and the feed accuracy and force stability of the drive systems of cylinders or hydraulic cylinders are relatively low. In addition, currently, most guide rails are installed by the way of bolts passing through and fixing. Due to errors and accuracy, etc., the slide rails will also displace and shake when the workpiece is stressed, resulting in limited machining accuracy of the workpiece. Summary of the Utility Model

[0005] In order to improve the machining accuracy of workpieces, the present application provides a moving sliding table.

[0006] A moving sliding table provided by the present application adopts the following technical solutions: It includes a sliding mechanism and a load platform installed on the sliding mechanism, and is characterized in that: the sliding mechanism includes at least one moving component, the moving component includes an installation platform, a screw drive component installed on the installation platform, at least one slide rail, and a slider slidably installed on the slide rail, and the load platform is connected to the slider;

[0007] At least one groove for the slide rail to be embedded is provided on the installation platform, and the installation platform is provided with a pressing block for pressing the slide rail against the side wall of the groove.

[0008] By adopting the above technical solutions, it is driven by the screw drive component to improve accuracy and force stability. In addition, the groove provides installation and positioning space for the slide rail, ensuring that the slide rail can be stably arranged on the installation platform and maintaining the accuracy and stability of its position; the groove cooperates with the pressing block, and the pressing block applies a force to the slide rail, so that the slide rail can be pressed against one side of the groove, reducing the shaking of the slide rail during use and reducing the shear force on the bolts fixing the guide rail and the installation platform.

[0009] Optionally, a plurality of notches are provided on the side of the mounting table, the notches extend into the groove, and the pressing block is mounted in the notches by bolts.

[0010] By adopting the above technical solution, the notches facilitate the installation of the pressing block, and the force for pressing against the sliding rail is applied to the pressing block through the action of the bolts. The notches extend into the groove, so that the pressing block can directly and effectively transfer the pressure to the sliding rail.

[0011] Optionally, a protruding portion is provided on the side of the pressing block, and the protruding portion abuts against the side of the sliding rail under the pressing of the pressing block. A supporting portion is provided on the side of the pressing block, and the supporting portion abuts against the inner wall of the notch under the pressing of the pressing block.

[0012] By adopting the above technical solution, the pressing block can directly contact the side of the sliding rail through the protruding portion, preventing the inner wall of the notch from blocking the pressing block and causing the pressing block to be unable to press against the sliding rail tightly. The supporting portion provides a supporting point for the pressing block, so that the pressing block can be inclined during the abutting process.

[0013] Optionally, at least one end of the groove is not provided with a block.

[0014] By adopting the above technical solution, when the sliding rail needs to be replaced, only the bolts pressing the pressing block and the bolts fixing the guide rail to the mounting platform need to be loosened and removed, and then the sliding rail can be pulled out from the end of the groove without a block. In this way, the replacement of the sliding rail can be completed quickly without disassembling all the structures.

[0015] Optionally, the groove is in clearance fit with the sliding rail.

[0016] By adopting the above technical solution, a small gap of - mm is left, which facilitates the sliding rail to be relatively easily installed into the groove, reduces the jamming and friction during the installation process, and improves the installation efficiency.

[0017] Optionally, a plurality of second threaded holes are provided on the bottom wall of the groove, and a plurality of second stepped holes are provided on the guide rail. The groove is connected to the second threaded holes by bolts.

[0018] By adopting the above technical solution, the groove and the tightening mechanism limit the movement of the sliding rail in the width direction, and the sliding rail is fixed in the groove by bolts to ensure that the sliding rail is not easily loosened during operation.

[0019] Optionally, the loading platform is provided with a plurality of through mounting grooves, and the mounting grooves are in an inverted T-shape.

[0020] By adopting the above technical solution, the inverted T-shaped mounting grooves are for loading the clamping device to avoid interference from other parts and facilitate the installation of the clamping device.

[0021] In summary, the present application includes at least one of the following beneficial technical effects:

[0022] 1. Improve installation positioning accuracy and stability: The groove of the installation table provides a precise installation positioning space for the slide rail. Cooperating with the pressing block makes the slide rail stable, reduces shaking, ensures the precise and stable movement of the load table, and also reduces the shear force on the fixing bolts, extending their service life.

[0023] 2. Facilitate installation, maintenance, and replacement: The width of the groove is slightly larger than the width of the slide rail, reducing installation jamming friction, and there is no obstruction at one end. When replacing the slide rail, only need to loosen the relevant bolts and then pull it out, without completely disassembling, greatly improving the efficiency of installation and maintenance.

[0024] 3. Achieve high-precision linear motion control: The lead screw drive assembly uses a lead screw and a lead screw block driven by a servo motor, which can provide high-precision speed and rotation angle control, enabling the load table to achieve precise linear motion and meeting different position accuracy requirements.

[0036] The following is further detailed description of this application in combination with the attached Figure 1 - attached Figure 9 to this application.

[0037] The embodiment of this application discloses a moving slide table.

[0038] Referring to Figure 1 , a moving slide table includes a first moving component 11, a second moving component 12 and a carrying platform 2. The second moving component 12 is carried on the moving end of the first moving component 11, and the carrying platform 2 is installed on the moving end of the second moving component 12. Through the first moving component 11 and the second moving component 12, the carrying platform 2 can move along the XY direction. Both the first moving component 11 and the second moving component 12 belong to the sliding mechanism 1. In this embodiment, taking the XY moving slide table composed of two sliding mechanisms 1 as an example, it can also be a multi-directional moving slide table composed of multiple sliding mechanisms 1.

[0039] Referring to Figure 2 , the first moving component 11 includes a slide rail 4, a slide block 5 and an installation table 3. The installation table 3 is processed with grooves 31. In this embodiment, two grooves 31 are taken as an example and are arranged on the top surface of the installation table 3. The slide rail 4 is arranged in the grooves 31, the slide block 5 is slidably connected with the slide rail 4, the second moving component 12 is fixed on the slide block 5 by bolts, a lead screw driving component 6 for driving the second moving component 12 to move is arranged between the two grooves 31, and a plurality of notches 33 are arranged on both sides of the installation table 3. The notches 33 extend into the grooves 31, and a pressing block 32 for pressing the slide rail 4 against one side of the groove 31 is arranged in the groove 31.

[0040] Referring to Figure 3 and Figure 4, several second threaded holes 32 are provided on the bottom surface of the groove 31, and the slide rail 4 is provided with a through second stepped hole 41. A bolt passes through the second stepped hole 41 and is threadedly connected to the second threaded hole 32. Since the slide rail 4 is pressed against one side of the groove 31 by the pressing block 32, the force on the slide rail 4 in the width direction is restricted. Only a small number of bolts are needed to fix the slide rail 4 in the groove 31, and it has a good stability effect; one end of the groove 31 communicates with the side surface of the mounting table 3, and the width of the groove 31 is 0-1 mm greater than the width of the slide rail 4, so that the slide rail 4 can move in the groove 31. When the slide rail 4 needs to be replaced, the slide rail 4 can be withdrawn from the open end of the groove 31.

[0041] Reference Figure 5 and Figure 6 , the notch 33 communicates with the top surface of the mounting table 3, and the notch 33 extends into the groove 31 by 0-0.5 mm. As Figure 6 shown, the groove 31 is milled on the top surface of the mounting table 3, and the notch 33 is milled on the side surface of the mounting table 3. During the milling process of the notch 33, part of the inner wall of the groove 31 will be milled off, so that the notch 33 communicates with the groove 31; the notch 33 is provided with a first threaded hole 35, and the perpendicular line of the first threaded hole 35 is perpendicular to the side wall of the groove 31.

[0042] Reference Figure 6 and Figure 7 , on the same side of the pressing block 34, there are a convex part 342 and a supporting part 343. A first stepped hole 341 passing through the pressing block 34 is provided between the convex part 342 and the supporting part 343. A bolt passes through the first stepped hole 341 and is threadedly connected to the first threaded hole 35. The bolt will apply a pressing force to the pressing block 34 to press the slide rail 4, so that the convex part 342 abuts against the slide rail 4, and the supporting part 343 abuts against the inner wall of the notch 33. The pressing force is applied to the slide rail 4 through the convex part 342.

[0043] Reference Figure 8 , the lead screw drive assembly 6 includes a lead screw 61 and a lead screw block 62. The lead screw 61 is arranged between two slide rails 4. The lead screw 61 is threadedly connected to the lead screw block 62. The lead screw block 62 is fixedly connected to the second moving assembly 12. The lead screw 61 is externally connected to a servo motor. The position of the second moving assembly 12 is accurately adjusted through the servo motor. The servo motor can provide high-precision speed and angle control. Through cooperation with the lead screw, very accurate linear motion of the carrier table can be achieved, meeting the requirements for position accuracy.

[0044] Reference Figure 9 , the principle of the second moving assembly 12 is the same as that of the first moving assembly 11. The difference between the two lies in the mounting table 3. The mounting table 3 in the second moving assembly 12 is not only used to carry relevant corresponding parts, but also connected to the output end of the lead screw drive assembly 6 in the first moving assembly 11. The output end of the lead screw drive assembly 6 in the second moving assembly 12 is fixedly connected to the carrier table 2.

[0045] Reference Figure 10 The stage 2 is provided with a number of through mounting grooves 21. The mounting grooves 21 are in an inverted T shape. Bolts are inverted and embedded in the mounting grooves 21. The stage 2 is equipped with a clamping device for clamping workpieces through bolts and nuts. A connecting portion 22 fixedly connected to the lead screw block 62 in the second moving assembly 12 is provided at the bottom end of the stage 2.

[0046] The above are all the preferred embodiments of this application, and the protection scope of this application is not limited thereby. Therefore, all equivalent changes made according to the structure, shape, and principle of this application should be covered within the protection scope of this application.
