Description

Technical Field

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

[0002] A horizontal machining center is a high-performance CNC machine tool. Its core feature is that the spindle is horizontally positioned. Compared to a vertical machining center, the worktable of a horizontal machining center is usually an indexable rotary table (i.e., a CNC rotary table). After the workpiece is clamped once, the worktable can be rotated to complete the machining of the other four sides (excluding the mounting surface) and multiple angles. It is very suitable for machining complex parts such as box-shaped and shell-shaped parts. The lifting structure (also known as the Y-axis drive mechanism) is a key functional component that realizes the relative movement between the tool and the workpiece in the vertical direction (Y-axis). Its performance directly determines the machining accuracy, dynamic response, load-bearing capacity, and overall rigidity of the machine tool. This is its most basic function: to control the precise positioning of the tool on the Y-axis (vertical direction) after the Z-axis (spindle axis) and X-axis (horizontal transverse direction) are determined, so as to complete the machining of complex surfaces. The lifting table (or slide) needs to install heavy tool magazines, robotic arms, spindle boxes, and other components. Therefore, its structure must have extremely high rigidity and strength. Under heavy load and high-speed movement, deformation and vibration must be minimized to ensure the dimensional accuracy, shape accuracy, and surface finish of the machining. Modern machining pursues high efficiency and requires the lifting structure to start, accelerate, and stop quickly and smoothly to reduce non-machining time.

[0003] When working, horizontal lathes often lack support for excessively long parts, which is not conducive to the machining of parts. Utility Model Content

[0004] To achieve the above objectives, this utility model provides the following technical solution: a lifting structure for a horizontal machining center, comprising a support base plate, a sliding rail fixedly connected to the top of the support base plate, a first motor fixedly connected to one end of the top of the sliding rail, a forward screw fixedly connected to the drive shaft of the first motor, a reverse screw fixedly connected to the side of the forward screw, a support device sleeved and threadedly connected to the side of the reverse screw, the bottom of the support device slidably connected to the top of the sliding rail, and a lifting device fixedly connected to the bottom of the support base plate. When the first motor is started, the drive shaft of the first motor rotates, driving the forward screw to rotate, which in turn drives the reverse screw to rotate. The rotation of the forward and reverse screws causes multiple sets of support devices to move synchronously, thereby increasing the coverage area between the multiple sets of support devices. This facilitates the support of parts of different lengths. The support devices support the parts, thus facilitating the rotational support of the parts during machining on a horizontal lathe, thereby enabling rotational support of the parts.

[0005] Preferably, the support device includes a sliding seat, a slide bar fixedly connected to the bottom of the sliding seat, an elastic bracket fixedly connected to the side of the sliding seat, an electric telescopic rod fixedly connected to the top side of the elastic bracket, the movable end of the electric telescopic rod passing through the side of the elastic bracket and slidably connected to the elastic bracket, a support assembly fixedly connected to the movable end of the electric telescopic rod, the sliding seat being slidably connected to the top of the sliding track via the slide bar, and a forward screw passing through the side of the sliding seat and threadedly connected to the sliding seat.

[0006] Preferably, the support assembly includes a connecting seat, a rotating frame fixedly connected to the side of the connecting seat, a rotating shaft rotatably connected to the inner wall of the rotating frame via a rotating shaft, a support ring sleeved and fixedly connected to the side of the rotating shaft, and the bottom of the connecting seat fixedly connected to the movable end of the electric telescopic rod. The part directly contacts the side of the support ring, the rotating shaft provides rotational support to the support ring, and the support ring increases the effective contact area with the part, thereby increasing the stability of the part support. The electric telescopic rod supports parts of different sizes. The elastic bracket facilitates elastic support for the parts, allowing the parts to absorb vibrations during processing, thus facilitating stable support. The sliding seat and slide bar enable sliding movement on the top of the sliding track, thereby covering parts of different lengths.

[0007] Preferably, the lifting device includes a bottom support, a worm gear rotatably connected to the top of the bottom support, a stud threaded through and connected to the top of the worm gear, a support frame fixedly connected to the top of the stud, an electric worm gear meshing with the side of the worm gear, a positioning slide rod threaded through and slidably connected to the top of the bottom support on one side of the worm gear, a fixed connection between the top of the support frame and the bottom of the support base plate, a fixed connection between the top of the positioning slide rod and the bottom of the support base plate, and a fixed connection between the side of the electric worm gear and the top of the support base plate via the support. When the electric worm gear is activated, its rotation drives the worm gear to rotate, which in turn moves the stud, causing the support frame to move up and down. This facilitates the raising or lowering of parts, and the threaded engagement of the worm gear and stud allows the support frame to maintain a stable height without external force intervention. Stable movement is achieved through the sliding connection between the positioning slide rod and the top of the bottom support.

[0008] This utility model provides a lifting structure for a horizontal machining center. It has the following beneficial effects: 1. This horizontal machining center uses a lifting structure and is equipped with a first motor. The rotation of the drive shaft of the first motor drives the forward screw to rotate, and the rotation of the forward screw drives the reverse screw to rotate. The rotation of the forward and reverse screws drives multiple sets of support devices to move synchronously, thereby increasing the coverage area between the multiple sets of support devices. This facilitates the support of parts of different lengths. The support devices support the parts, thus facilitating the rotational support of the parts while machining on the horizontal lathe, thereby facilitating the rotational support of the parts.

[0009] 2. This horizontal machining center uses a lifting structure with a support ring. The part directly contacts the side of the support ring, and the rotating shaft provides rotational support for the support ring. The support ring increases the effective contact area with the part, thereby increasing the stability of the part support. It supports parts of different sizes through an electric telescopic rod. The elastic bracket facilitates elastic support for the parts, allowing the parts to absorb vibrations during machining and ensuring stable support. The sliding seat and slide bar enable sliding movement on the top of the sliding track, thus covering parts of different lengths.

[0010] 3. This horizontal machining center uses a lifting structure and is equipped with an electric worm gear. When the electric worm gear is started, its rotation drives the worm wheel to rotate, which in turn drives the stud to move. The stud's movement causes the support frame to move up and down, thus facilitating the raising or lowering of parts. The threaded engagement between the worm wheel and the stud ensures that the support frame remains at a stable height without external force intervention. Stable movement is achieved through the sliding connection between the positioning slide rod and the top of the bottom support. Attached Figure Description
