Description

Technical Field

[0001] This utility model relates to the field of horizontal machining center technology, specifically to a rotation limiting structure for a horizontal machining center worktable. Background Technology

[0002] A horizontal machining center is a machining center in which the spindle axis is set parallel to the worktable. It is mainly suitable for machining box-shaped parts. The working principle is that after the workpiece is clamped on the machining center once, the computer can automatically select different tools and automatically change the spindle speed of the machine tool to complete the machining of multiple surfaces of the workpiece in sequence.

[0003] Application number CN201920107854.8 discloses a rotary table for a horizontal machining center. This table can position and clamp a workpiece. When machining one side of the workpiece, the drive mechanism rotates the table 90° in both directions, ensuring the surface to be machined is on one side of the machine spindle, thus completing the machining of the other side. This eliminates the need for manual clamping after machining one side, saving clamping time and improving machining efficiency and accuracy. However, this design has limitations. The rotary table lacks horizontal rotation capability, restricting its applicability to workpieces requiring multi-directional horizontal machining and failing to meet the needs of more complex machining scenarios.

[0004] Therefore, we propose a rotation limiting structure for the worktable of a horizontal machining center. Utility Model Content

[0005] The main purpose of this utility model is to provide a horizontal machining center worktable rotation limiting structure with excellent horizontal rotation function, which greatly expands the applicability of machining scenarios. The ball bearings are evenly distributed between the support plate and the mounting base, which greatly reduces the friction and shaking during the rotation of the support plate, making the rotation of the worktable more stable and smooth, and can effectively solve the problems in the background technology.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A horizontal machining center worktable rotation limiting structure includes a base and a mounting mechanism. The worktable is mounted on the upper surface of the base and is assembled on the mounting mechanism. The mounting mechanism includes a support plate, ball bearings, a rotating shaft, a motor, an assembly seat, a positioning component, a slip ring, a first bolt, a first fastener, and a second fastener. Both the support plate and the assembly seat are circular plate structures. The support plate is located directly above the assembly seat. An embedded groove for mounting the base is provided at the center of the upper surface of the support plate. The bottom end of the support plate is connected to the top of the assembly seat via a rotating shaft at the center. A limiting component for limiting the position of the slip ring is provided at the outer edge of the top of the assembly seat. The limiting component has a mounting cavity for accommodating the support plate. The limiting component includes a first fastener and a second fastener, both of which are circular ring structures. The bottom end of the first fastener is fastened to the top end of the second fastener. The inner walls of the first and second fasteners are provided with an arc-shaped groove that matches the outer side of the slip ring. The mounting base has a cavity for installing the motor at its center.

[0007] By adopting the above technical solution, it has excellent horizontal rotation function, which greatly expands the applicability of processing scenarios. The balls are evenly distributed between the support plate and the mounting base, which greatly reduces the friction and shaking during the rotation of the support plate, making the rotation of the worktable more stable and smooth, thereby effectively reducing the deviation during the rotation process and ensuring the positioning accuracy of the worktable when it rotates to the specified angle.

[0008] Specifically, ball bearings are provided between the support plate and the mounting base, the top end of the rotating shaft is vertically inserted into the center of the lower end face of the support plate, and the bottom end of the rotating shaft passes through the top end of the mounting base and is connected to the output shaft at the top of the motor via a coupling.

[0009] Specifically, the base is horizontally assembled in the embedded groove, and the base is fixedly connected to the upper surface of the support plate by a positioning component and a first bolt.

[0010] Specifically, a positioning groove for installing a slip ring is provided at the center of the outer side of the support plate, and the slip ring is engaged with the support plate.

[0011] Specifically, the slip ring has a circular ring structure, and the inner wall of the slip ring is provided with an assembly groove that matches the positioning groove.

[0012] Specifically, the top of the mounting base is provided with a drain hole that communicates with the mounting cavity, and there are multiple sets of drain holes.

[0013] The beneficial effects of this utility model are as follows: The horizontal machining center worktable rotation limiting structure described in this utility model has excellent horizontal rotation function, which greatly expands the applicability of machining scenarios. The balls are evenly distributed between the support plate and the mounting base, which greatly reduces the friction and shaking during the rotation of the support plate, making the rotation of the worktable more stable and smooth, thereby effectively reducing the deviation during the rotation process and ensuring the positioning accuracy of the worktable when it is rotated to a specified angle. With the first and second fasteners working closely together, the slip ring slides stably in the arc groove when the worktable rotates. Once the worktable rotates to the set limit angle, the slip ring will contact the inner wall of the limit component, immediately stopping the worktable from continuing to rotate. This effectively prevents the worktable from rotating excessively and ensures the positional accuracy and stability of the worktable during processing. Multiple sets of drainage holes are evenly distributed on the top of the mounting base, which can quickly and effectively drain liquid, keep the inside of the equipment dry and clean, and extend the service life of the equipment.

[0016] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0017] As one embodiment of this utility model, such as Figures 1-3As shown, the present invention discloses a horizontal machining center worktable rotation limiting structure, including a base 1 and a mounting mechanism 2. The worktable is mounted on the upper surface of the base 1 and is mounted on the mounting mechanism 2. The mounting mechanism 2 includes a support plate 3, ball bearings 4, a rotating shaft 5, a motor 6, a mounting seat 7, a positioning component 8, a slip ring 11, a first bolt 13, a first fastener 15, and a second fastener 16. The support plate 3 and the mounting seat 7 are both circular plate structures. The support plate 3 is located directly above the mounting seat 7. The upper surface of the support plate 3 has an embedded groove 12 for mounting the base 1 at its center. The bottom of the support plate 3 is connected to the top of the mounting seat 7 via the rotating shaft 5 at its center. The outer edge of the top of the mounting seat 7 has a limiting component for limiting the position of the slip ring 11. The limiting component has a mounting cavity 9 for accommodating the support plate 3. The limiting component includes a first fastener 15 and a second fastener 16. Both the first fastener 15 and the second fastener 16 are circular ring structures. The bottom end of the first fastener 15 is fastened to the top end of the second fastener 16. The inner walls of the first fastener 15 and the second fastener 16 are provided with an arc-shaped groove that is adapted to the outer side of the slip ring 11. The mounting base 7 has a cavity for installing the motor 6 at its center.

[0018] During operation, the limiting structure plays a crucial role in the rotation of the worktable. The slip ring 11 rotates together with the support plate 3. When the worktable rotates to the set limit angle, the slip ring 11 contacts the inner wall of the limiting component. The limiting component consists of a first fastener 15 and a second fastener 16. The arc-shaped groove on its inner wall fits tightly with the outer side of the slip ring 11. When the slip ring 11 contacts the inner wall of the arc-shaped groove, it prevents the slip ring 11 from moving further, thereby indirectly limiting the rotation angle of the worktable, ensuring that the worktable does not rotate excessively, and guaranteeing the positional accuracy and stability of the workpiece during processing.

[0019] This utility model also includes a ball bearing 4 between the support plate 3 and the mounting base 7, the top end of the rotating shaft 5 being vertically inserted at the center of the lower end face of the support plate 3, and the bottom end of the rotating shaft 5 passing through the top end of the mounting base 7 and connected to the output shaft at the top end of the motor 6 via a coupling.

[0020] The present invention also includes that the base 1 is horizontally assembled in the embedded groove 12, and the base 1 is fixedly connected to the upper end face of the support plate 3 by the positioning member 8 and the first bolt 13.

[0021] The present invention also includes a positioning groove 14 for installing a slip ring 11 at the center of the outer side of the support plate 3, wherein the slip ring 11 is engaged with the support plate 3.

[0022] The present invention also includes that the slip ring 11 has a circular ring structure and the inner wall of the slip ring 11 is provided with an assembly groove that is adapted to the positioning groove 14.

[0023] The present invention also includes a drain hole 10 at the top of the mounting base 7 that communicates with the mounting cavity 9, and the drain hole 10 is provided in multiple sets.

[0024] In use, the base 1 is placed horizontally in the embedding groove 12 on the upper surface of the support plate 3, ensuring that the base 1 and the embedding groove 12 fit tightly together. The base 1 is then firmly fixed to the support plate 3 using the first bolt 13. The motor 6 drives the rotating shaft 5 to rotate through the output shaft. Under the drive of the rotating shaft 5, the support plate 3 rotates at the top of the mounting base 7, and the base 1 and the worktable installed in the embedding groove 12 on its upper surface also rotate together, realizing the horizontal rotation function of the worktable. During the rotation of the worktable, the limiting structure plays a crucial role. The slip ring 11 rotates together with the support plate 3. When the worktable rotates to the set limit angle, the slip ring 11 contacts the inner wall of the limiting component. The limiting component consists of the first fastener 15 and the second fastener 16. The arc-shaped groove on its inner wall fits tightly with the outer side of the slip ring 11. When the slip ring 11 contacts the inner wall of the arc-shaped groove, it prevents the slip ring 11 from moving further, thereby indirectly limiting the rotation angle of the worktable, ensuring that the worktable does not rotate excessively, and guaranteeing the positional accuracy and stability of the workpiece during processing.
