Description

Technical Field

[0001] This utility model relates to the technical field of auxiliary devices for laser processing equipment, specifically a silent slide rail type dual-station rotary platform. Background Technology

[0002] In the laser marking process of white desktop and other materials, large-enclosed laser marking machines are widely used due to their high processing precision and strong environmental adaptability.

[0003] However, most existing laser marking machines use a single-station fixed structure or a simple sliding platform for their worktables, which presents several limitations in actual production. The single-station design prevents the loading and unloading of materials from being synchronized with the marking operation. After marking a workpiece, the machine must be stopped to remove the finished product and reposition the workpiece to be processed, significantly reducing production efficiency. This is especially true when batch processing large materials such as white tabletops, where downtime has a more pronounced impact on production capacity. Furthermore, while some platforms employ a dual-station design, the spacing between the stations cannot be adjusted, making them unsuitable for different sizes of white tabletops. When processing large-diameter tabletops, insufficient spacing between the two stations restricts workpiece placement.

[0004] In view of this, we propose a silent sliding rail type dual-station rotary platform. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a silent slide rail type dual-station rotary platform.

[0006] The technical solution of this utility model is:

[0007] A silent sliding-rail type dual-station rotary platform includes an operating table. Two guide rail assemblies are symmetrically slidably mounted within a movable compartment on the top of the operating table. A turntable assembly is slidably mounted above each guide rail assembly. Two hydraulic cylinders are symmetrically fixed to the outer walls of both sides of the operating table. The guide rail assemblies and the piston rods of the two hydraulic cylinders on the same side are fixedly connected. Each turntable assembly includes a drive block slidably connected to the guide rail assembly. A mounting frame is fixedly connected to the top of the drive block, and a turntable body is rotatably mounted on the top of the mounting frame. A rotary motor with its output shaft coaxially fixed to the turntable body is installed inside the mounting frame. By setting up dual guide rail assemblies and a turntable assembly on the top of the operating table, and using hydraulic cylinders to drive the linear motion of the guide rails and a rotary motor to drive the circular motion of the turntable body, independent control and collaborative operation of the two workstations are achieved. Furthermore, the adjustable spacing of the two guide rails allows for adjustment of the distance between the two turntable assemblies during use, effectively increasing the diameter range of the tabletop that can be placed on the turntable assembly, thus enhancing its practicality.

[0008] As a preferred technical solution, a support leg is fixedly connected to each of the four corners of the bottom of the operating platform, providing a stable support structure for the entire device.

[0009] As a preferred technical solution, an anti-slip pad is fixedly connected to the top of the turntable body, and the top of the anti-slip pad is provided with evenly distributed anti-slip protrusions. The design of the anti-slip pad and anti-slip protrusions on the top of the turntable body enhances the friction between the tabletop and the turntable, effectively preventing the workpiece from sliding or displacing due to centrifugal force or external force during rotation.

[0010] As a preferred technical solution, the guide rail assembly includes a movable block slidably connected inside the movable compartment, with a guide rail body welded to the top of the movable block, and the turntable assembly slidably mounted on the guide rail body. This design confines the movement of the guide rail within the movable compartment, effectively preventing lateral displacement or wobbling of the guide rail during movement.

[0011] As a preferred technical solution, the movable block is fixedly connected to the piston rod of the hydraulic cylinder, and both ends of the movable block are tightly fitted against the inner wall of the movable chamber. This fitting structure can be considered a mechanical limiter, effectively suppressing the lateral swaying of the movable block during movement.

[0012] As a preferred technical solution, the top of the guide rail body has two symmetrically integrally formed support plates, and a lead screw is rotatably connected between the two support plates. The drive block has a threaded hole that is threadedly connected to the lead screw. An adjusting motor with an output shaft coaxially fixed to one of the support plates is fixedly installed. The linear motion of the turntable assembly is achieved through the cooperation between the lead screw and the threaded hole.

[0013] As a preferred technical solution, the drive block is provided with a limiting groove that slides in connection with the guide rail body, and the guide rail body has a T-shaped cross-section. This design not only restricts the vertical displacement of the drive block, but also withstands a certain lateral force, preventing the drive block from detaching from the guide rail during movement.

[0014] As a preferred technical solution, two support bars are symmetrically welded to the top of the guide rail body, and the inner wall of the top of the limiting groove is tightly fitted with the top of the support bars. The support bars effectively reduce the contact area between the guide rail body and the drive block, thereby effectively reducing the noise generated by the drive block during sliding.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] This invention achieves independent control and collaborative operation of two workstations by setting a double guide rail assembly and a turntable assembly on the top of the operating table, and using a hydraulic cylinder to drive the linear motion of the guide rails and a rotary motor to drive the circular motion of the turntable body. Furthermore, the adjustable spacing of the two guide rails allows for adjustment of the distance between the two turntable assemblies, effectively increasing the diameter range of the tabletop that can be placed on the turntable assembly, thus enhancing its practicality.

Detailed Implementation

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figures 1-4 This utility model provides a technical solution:

[0025] A silent sliding-rail type dual-station rotary platform includes an operating platform 1. Two guide rail assemblies 2 are symmetrically slidably installed within a movable compartment 10 at the top of the operating platform 1. A turntable assembly 3 is slidably installed above each guide rail assembly 2. Two hydraulic cylinders 4 are symmetrically fixedly installed on the outer walls of both sides of the operating platform 1. The piston rods of the guide rail assemblies 2 and the two hydraulic cylinders 4 on the same side are fixedly connected. The turntable assembly 3 includes a drive block 30 slidably connected to the guide rail assembly 2. A mounting frame 31 is fixedly connected to the top of the drive block 30. A turntable body 32 is rotatably mounted on the top of the mounting frame 31. A rotary motor 34, with its output shaft coaxially fixed to the turntable body 32, is installed inside the mounting frame 31. By setting up dual guide rail assemblies 2 and turntable assemblies 3 at the top of the operating platform 1, and using hydraulic cylinders 4 to drive the guide rails in linear motion and rotary motors 34 to drive the turntable body 32 in circular motion, independent control and collaborative operation of the two stations are achieved. Meanwhile, the two adjustable guide rails allow for adjustment of the distance between the two turntable components 3 during use, thereby effectively increasing the diameter range of the tabletop that can be placed on the turntable component 3 and enhancing its practicality during use.

[0026] In this preferred embodiment, a support leg 5 is fixedly connected to each of the four corners of the bottom of the operating table 1, providing a stable support structure for the entire device.

[0027] In a preferred embodiment, an anti-slip pad 33 is fixedly connected to the top of the turntable body 32, and the top of the anti-slip pad 33 is provided with evenly distributed anti-slip protrusions. The design of the anti-slip pad 33 and anti-slip protrusions on the top of the turntable body 32 enhances the friction between the table and the turntable, effectively preventing the workpiece from sliding or displacing due to centrifugal force or external force during rotation.

[0028] In a preferred embodiment, the guide rail assembly 2 includes a movable block 21 slidably connected inside the movable chamber 10, with a guide rail body 20 welded to the top of the movable block 21, and the turntable assembly 3 slidably mounted on the guide rail body 20. This design confines the movement of the guide rail within the movable chamber 10, effectively preventing lateral displacement or swaying of the guide rail during movement.

[0029] In a preferred embodiment, the movable block 21 is fixedly connected to the piston rod of the hydraulic cylinder 4, and both ends of the movable block 21 are tightly fitted against the inner wall of the movable chamber 10. The fitting structure can be regarded as a mechanical limit, which can effectively suppress the lateral swing of the movable block 21 during the movement.

[0030] In a preferred embodiment, the top of the guide rail body 20 has two symmetrically integrally formed support plates 22, and a lead screw 25 is rotatably connected between the two support plates 22. The drive block 30 has a threaded hole 301 that is threadedly connected to the lead screw 25. An adjusting motor 23 with its output shaft coaxially fixed to one of the support plates 22 is fixedly installed on it. The linear motion of the turntable assembly 3 is achieved through the cooperation between the lead screw 25 and the threaded hole 301.

[0031] As a preferred embodiment, the drive block 30 is provided with a limiting groove 300 that slides in connection with the guide rail body 20, and the guide rail body 20 has a T-shaped cross-section. This design not only restricts the vertical displacement of the drive block 30, but also withstands a certain lateral force, preventing the drive block 30 from detaching from the guide rail during movement.

[0032] In a preferred embodiment, two support bars 24 are symmetrically welded to the top of the guide rail body 20, and the inner wall of the top of the limiting groove 300 is in close contact with the top of the support bars 24. The support bars 24 can effectively reduce the contact area between the guide rail body 20 and the drive block 30, thereby effectively reducing the noise generated by the drive block 30 when sliding.

[0033] When using the silent sliding rail type dual-station rotary platform of this utility model, firstly, according to the size and specifications of the workpiece to be processed, the hydraulic cylinders 4 on both sides of the control table 1 are started. The piston rod of the hydraulic cylinder 4 pushes the movable block 21 to slide in the movable chamber 10, thereby causing the two guide rail assemblies 2 to move closer or further apart, thereby adjusting the initial distance between the two turntable assemblies 3.

[0034] After the spacing is adjusted, the tabletop is placed on the anti-slip pads 33 on top of the two turntable bodies 32. The anti-slip protrusions on the surface of the anti-slip pads 33 will increase the friction between the workpiece and the turntable, preventing the workpiece from shifting due to centrifugal force during subsequent rotation. Then, the adjustment motor 23 is started, and the motor output shaft drives the lead screw 25 to rotate. The lead screw 25 engages with the threaded hole 301 on the drive block 30, causing the turntable assembly 3 to slide along the guide rail body 20.

[0035] Once the turntable assembly 3 moves to the designated processing position, the rotary motor 34 inside the mounting bracket 31 starts, and its output shaft drives the turntable body 32 to rotate, thereby driving the workpiece to adjust its circumferential angle to meet different processing requirements. During the entire operation, if it is necessary to switch the processing position of the workpiece, the turntable assembly 3 can be slid again by adjusting the motor 23, or the position of the guide rail assembly 2 can be adjusted by the hydraulic cylinder 4.

[0036] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
