Description

Technical Field

[0001] This utility model relates to the technical field of gantry machining equipment, specifically a gantry machining structure with a rotating worktable. Background Technology

[0002] A gantry machining center is a large machine tool whose main structural feature is a gantry-shaped frame. This frame typically consists of two uprights and a crossbeam. The uprights are perpendicular to the ground and support the crossbeam. The gantry frame is the key component of the entire machine, providing strong rigidity to ensure it can withstand enormous cutting forces during machining without excessive deformation. Below the gantry frame is the worktable, used to place and hold the workpiece to be machined. With economic development and the increasing demands of the manufacturing industry, large-scale machine tools have become a better choice for improving efficiency and reducing costs, especially when machining large workpieces.

[0003] Existing technology, such as publication number CN203556928U, provides a gantry milling machine, including a base, a worktable movable along the upper surface of the base, columns on both sides of the base, and a crossbar at the top of the two columns; two first slide rails on the top surface of the crossbar, and a second slide rail on the front side of the crossbar; and a machining table with an L-shaped body, two first grooves sliding along the first slide rails on the lower side of one end of the L-shaped body, and a second groove sliding along the second slide rail on the lower side of the other vertical end of the L-shaped body; thus, the gantry milling machine of this utility model can process quickly and efficiently; and is more stable during processing, improving the efficiency of finished products.

[0004] Existing three-axis gantry machining centers (with X, Y, and Z linear axes) can process multiple sides to a certain extent, primarily by moving the gantry and cutting tool to achieve machining at different positions on the workpiece. However, for complex shapes or sides requiring machining on non-perpendicular planes, three-axis gantry machining centers may encounter difficulties. Because they lack the function to change the relative angle between the cutting tool and the workpiece, when machining inclined surfaces or sides with complex contours, the cutting tool may not be able to properly conform to the workpiece surface, easily leading to decreased machining accuracy or requiring additional tooling fixtures to adjust the workpiece angle. Therefore, we propose a gantry machining structure with a rotary table. Summary of the Invention

[0005] The purpose of this utility model is to provide a gantry machining structure with a rotary worktable. This gantry machining structure with a rotary worktable solves the problem that three-axis gantry machining equipment may encounter difficulties when machining some complex shapes or sides that need to be machined on non-vertical planes. This is because it lacks the function of changing the relative angle between the tool and the workpiece. When machining inclined surfaces or sides with complex contours, it may not be able to make the tool fit the workpiece surface well, which can easily lead to a decrease in machining accuracy or the need for additional tooling fixtures to adjust the workpiece angle.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A gantry machining structure with a rotating worktable includes a base, and the worktable is provided on the top of the base;

[0008] The workbench includes a base, which is disposed above a base plate. A support column is fixedly connected to the top of the base, and a bearing platform is disposed above the support column. Connecting shafts are fixedly connected to both sides of the bearing platform. A row of hydraulic cylinders is hinged to both sides of the base, and one end of the top of each hydraulic cylinder is rotatably connected to the outer wall of the corresponding connecting shaft via a ring.

[0009] Preferably, a connecting seat is provided at the bottom of the support platform at the position of the support column, and the inner wall of the connecting seat cooperates with the outer wall of the support column.

[0010] Preferably, the support column is equipped with an electromagnet for magnetically adsorbing the connecting seat.

[0011] Preferably, when the support platform is in a horizontal state, the hydraulic cylinders on both sides are tilted 30 degrees away from the support platform.

[0012] Preferably, the top of the support platform is provided with a T-slot for installing and fixing clamping fixtures.

[0013] Preferably, the base has columns on both sides, and a crossbeam is fixedly connected to the top of the two columns. A lifting platform is slidably connected to the crossbeam, and a cutting device is slidably connected to the lifting platform.

[0014] Preferably, the base is provided with a linear guide rail for driving the worktable to move in the X-axis direction, the crossbeam is provided with a linear guide rail for driving the lifting platform to move in the Y-axis direction, and the lifting platform is provided with a linear guide rail for driving the cutting device to move in the Z-axis direction.

[0015] By employing the above technical solution, this utility model provides a gantry machining structure with a rotary worktable. It possesses at least the following beneficial effects:

[0016] I. This utility model, by disassembling the worktable into a base and a support platform, allows the support platform to tilt when the hydraulic cylinders on both sides of the base and support platform extend and retract, thereby tilting the workpiece being processed. This facilitates processing the workpiece within a certain tilt angle, avoiding the problem that conventional three-axis gantry machining equipment may lack the function to change the relative angle between the tool and the workpiece. When processing inclined surfaces or sides with complex contours, the tool may not be able to fit well against the workpiece surface, which can easily lead to a decrease in machining accuracy.

[0017] II. When processing a workpiece, this utility model uses a linear guide rail on the base to drive the worktable to move in the X direction, thereby driving the workpiece to move in the X direction. The linear guide rail on the crossbeam to drive the lifting platform to move in the Y direction and the linear guide rail on the lifting platform to drive the cutting device to move in the Z direction work together to enable the cutting device to move in the Z and X directions, so as to facilitate the processing of the workpiece in the X, Y and Z directions by the programmed program.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0025] A gantry machining structure with a rotary table, such as Figure 1 - Figure 4 As shown, the system includes a base 1, a worktable 6 on top of the base 1, and a base 61 on top of the base 1. A support column 63 is fixedly connected to the top of the base 61, and a bearing platform 62 is mounted above the support column 63. Connecting shafts 65 are fixedly connected to both sides of the bearing platform 62. A row of hydraulic cylinders 66 is hinged to both sides of the base 61, and one end of the top of each hydraulic cylinder 66 is rotatably connected to the outer wall of the corresponding connecting shaft 65 via a ring. A connecting seat 64 is provided at the bottom of the bearing platform 62 opposite to the support column 63. The inner wall of the connecting seat 64 cooperates with the outer wall of the support column 63. An electromagnet is installed inside the support column 63 to magnetically attract the connecting seat 64. When the bearing platform 62 is in a horizontal state, the hydraulic cylinders 66 on both sides tilt 30 degrees away from the bearing platform 62. This tilting allows the bearing platform 62 to have a higher tilt angle. A T-slot is provided on the top of the bearing platform 62 for installing and fixing clamping fixtures.

[0026] In this embodiment, by splitting the worktable 6 into a base 61 and a support platform 62, the hydraulic cylinders 66 on both sides of the base 61 and the support platform 62 can tilt the support platform 62 when they extend or retract, thus tilting the workpiece being processed. This facilitates processing the workpiece within a certain tilt angle, avoiding the problem that conventional three-axis gantry machining equipment may lack the function to change the relative angle between the tool and the workpiece. When processing inclined surfaces or sides with complex contours, the tool may not be able to fit well against the workpiece surface, easily leading to a decrease in processing accuracy. In actual use, when the support platform 62 needs to be adjusted, the hydraulic cylinder 66 on one side retracts while the hydraulic cylinder 66 on the other side extends, causing the support platform 62 to rotate around the support column 63. After the workpiece angle on the support platform 62 is adjusted, while the hydraulic cylinder 66 is in the current extended or retracted state, the electromagnet inside the support column 63 is activated, and the support platform 62 is magnetically attracted to the connecting seat 64 below it to fix it, thus maintaining the stability of the workpiece on the support platform 62 during processing.

[0027] like Figure 1 As shown, preferably, the base 1 has columns 2 on both sides, and the top of the two columns 2 is fixedly connected to a crossbeam 3. A lifting platform 4 is slidably connected to the crossbeam 3, and a cutting device 5 is slidably connected to the lifting platform 4. The base 1 is provided with a linear guide rail for driving the worktable 6 to move in the X-axis direction, the crossbeam 3 is provided with a linear guide rail for driving the lifting platform 4 to move in the Y-axis direction, and the lifting platform 4 is provided with a linear guide rail for driving the cutting device 5 to move in the Z-axis direction.

[0028] In this embodiment, when processing the workpiece, the linear guide rail on the base 1 that drives the worktable 6 to move in the X direction is used to drive the workpiece on the worktable 6 to move in the X direction. The linear guide rail on the crossbeam 3 that drives the lifting platform 4 to move in the Y direction and the linear guide rail on the lifting platform 4 that drives the cutting device 5 to move in the Z direction cooperate to enable the cutting device 5 to move in the Z and X directions, so as to facilitate the processing of the workpiece in the X, Y and Z directions by the programmed program.

[0029] In the gantry machining structure with a rotating worktable of this utility model, when the support platform 62 needs to be adjusted, the hydraulic cylinder 66 on one side retracts while the hydraulic cylinder 66 on the other side extends, causing the support platform 62 to rotate around the support column 63. After the workpiece angle on the support platform 62 is adjusted, with the hydraulic cylinder 66 in its current extension / retraction state, the electromagnet inside the support column 63 is activated, magnetically adsorbing the connecting seat 64 below the support platform 62 to fix it, thus maintaining the stability of the workpiece during machining. When machining the workpiece, the linear guide rail on the base 1 that drives the worktable 6 to move in the X-axis direction drives the workpiece on the worktable 6 to move in the X-direction. The linear guide rail on the crossbeam 3 that drives the lifting platform 4 to move in the Y-direction and the linear guide rail on the lifting platform 4 that drives the cutting device 5 to move in the Z-direction cooperate to enable the cutting device 5 to move in the Z-axis and X-axis directions, so as to facilitate the machining of the workpiece in the X, Y, and Z-axis directions according to the programmed program.
