Description

Technical Field

[0001] This utility model relates to the field of gantry machining centers, specifically a gantry machining center for machining heavy parts. Background Technology

[0002] A gantry machining center is a machining center in which the spindle axis is set perpendicular to the worktable. It is mainly suitable for machining large parts, such as machine tool beds, frames, and housings. In the machining of heavy parts, it is often necessary to perform multiple processes such as milling, drilling, and boring on different sides and angles of the parts.

[0003] In the existing technology, the worktable of traditional gantry machining centers is mostly a fixed structure or can only realize simple translational movement. When it is necessary to process heavy parts, the heavy parts need to be moved to the worktable and processed by the tool on the machining spindle.

[0004] However, when heavy parts are being machined for angle adjustment, external hoisting equipment is required to lift the parts, adjust their posture, and then re-clamp and fix them. This makes it inconvenient to adjust the angle of heavy parts, resulting in a cumbersome adjustment process that requires multiple hoisting, positioning, and clamping operations, which consumes a lot of manpower and time and seriously affects processing efficiency. Therefore, in order to address the above problems, a gantry machining center for machining heavy parts is proposed. Utility Model Content

The parts processing mechanism can control a milling cutter 16 to move horizontally and vertically, and the milling cutter 16 can rotate to process heavy parts. An electric slide 4 is fixedly mounted on the base 1, and an electric slide block 5 is slidably connected to the electric slide 4. This structure allows heavy workpieces on the turntable 10 to be moved below the milling cutter 16 for processing. A support 6 is fixedly installed above the workpiece, and an angle adjustment mechanism is installed on the support 6. Through the structure of the angle adjustment mechanism, the angle of the heavy workpiece can be adjusted in the horizontal direction. The angle adjustment mechanism includes a device cavity opened in the support 6, in which a first motor 7 is installed. A drive gear 8 is installed at the output end of the first motor 7. A driven shaft gear 9 is rotatably installed above the device cavity. The teeth of the drive gear 8 mesh with the teeth of the driven shaft gear 9. A turntable 10 is fixedly installed above the support 6. The shaft of the turntable 10 is fixedly connected to the shaft of the driven shaft gear 9. A flip adjustment and positioning mechanism is installed on the turntable 10. Through the structure of the flip adjustment and positioning mechanism, the heavy parts are clamped and positioned, and the flip angle of the heavy parts is controlled for adjustment, which is convenient for the operator to adjust and use.

[0021] Reference Figure 1 The parts processing mechanism includes a transverse electric slide rail 11 fixedly mounted on a crossbeam 3, a drive block 12 slidably connected to the transverse electric slide rail 11, a longitudinal electric slide 13 fixedly mounted on the front side of the drive block 12, an electric slide plate 14 slidably connected to the longitudinal electric slide plate 13, a spindle box 15 fixedly mounted on the electric slide plate 14, and a milling cutter 16 mounted on the output end of the spindle box 15. Through the structural configuration of the parts processing mechanism, the milling cutter 16 can be controlled to move horizontally and vertically, and the milling cutter 16 can rotate to process heavy parts.

[0022] Reference Figure 3 and Figure 4 A ring groove 17 is provided above the support 6, and multiple auxiliary sliding columns 18 are fixedly provided below the turntable 10. The multiple auxiliary sliding columns 18 are slidably connected to the ring groove 17 to improve the load-bearing capacity of the turntable 10.

[0023] Reference Figure 3 and Figure 5The flip adjustment and positioning mechanism includes a set of flip brackets 19 symmetrically arranged on the turntable 10. A flip shaft 20 is rotatably arranged above the flip brackets 19. Support arms 21 are fixedly arranged on the inner ends of the two flip shafts 20 respectively. A motor bracket is fixedly arranged on one side of the flip bracket 19. A second motor 22 is arranged on the motor bracket. A reduction gearbox 23 is arranged on the output end of the second motor 22. The input end of the reduction gearbox 23 is connected to the corresponding flip shaft 20 through a coupling. A part positioning component is arranged on the support arm 21. Through the structural arrangement of the flip adjustment and positioning mechanism, heavy parts are clamped and positioned, and the flip angle of the heavy parts is controlled for adjustment, which is convenient for workers to adjust and use.

[0024] Reference Figure 3 and Figure 5 The part positioning assembly includes heavy-duty dual-axis cylinders 24 fixedly mounted on both sides of the support arm 21. The piston rod of the heavy-duty dual-axis cylinder 24 passes through the support arm 21 and is fixedly mounted on a mounting plate 25. A clamping element 26 is detachably mounted on the mounting plate 25. It is worth noting that the clamping element 26 can be replaced with a matching clamping element 26 according to the actual processing of the heavy parts. Through the structural design of the part positioning assembly, sufficient clamping force can be provided to the clamping element 26 to firmly position the heavy parts on the flipping adjustment positioning mechanism, which facilitates the adjustment of the flipping angle during the subsequent processing of the heavy parts.

[0025] Reference Figure 1 and Figure 3 A pad 27 is fixedly provided on the upper part of the clamping member 26. The pad 27 is provided with anti-slip texture. The anti-slip texture on the pad 27 can increase the friction between the clamping member 26 and the heavy parts, and further improve the clamping effect on the heavy parts.

[0026] Reference Figure 1 An auxiliary hydraulic lifting platform 28 is fixedly installed above the turntable 10. The auxiliary hydraulic lifting platform 28 is located in the middle of the upper part of the turntable 10. With this structure, heavy parts are pre-placed on the auxiliary hydraulic lifting platform 28. By controlling the operation of the auxiliary hydraulic lifting platform 28, the heavy parts are lifted to a suitable position, so that the part positioning component can position the heavy parts. After the heavy parts are positioned, the auxiliary hydraulic lifting platform 28 is controlled to reset.

[0027] Working principle: When processing heavy parts, the operator pre-places the heavy parts on the auxiliary hydraulic lifting platform 28. By controlling the operation of the auxiliary hydraulic lifting platform 28, the heavy parts are lifted to a suitable position, so that the part positioning component can position the heavy parts. By adjusting the structure of the flipping positioning mechanism, heavy parts are clamped and positioned, and the flipping angle of the heavy parts is adjusted to facilitate adjustment by the staff. Through the operation of the part positioning component, the clamping component 26 matching the heavy parts is installed on the mounting plate 25. The heavy-duty dual-axis cylinders 24 on both sides of the support arm 21 operate, which can provide sufficient clamping force to the clamping component 26. The anti-slip texture on the pad 27 can increase the friction between the clamping component 26 and the heavy parts, further improving the clamping effect of the heavy parts. At this time, the auxiliary hydraulic lifting platform 28 is reset and the second motor 22 is operated, so that the two flipping shafts 20 rotate synchronously and flip the heavy parts at an angle. By adjusting the angle of the mechanism, the heavy workpiece can be adjusted in the horizontal direction, so that it can be processed from multiple angles. Through controlled operation, the drive gear 8 engages with the driven shaft gear 9. At this time, the upper turntable 10 of the support 6 rotates, and the multiple auxiliary sliding columns 18 below the turntable 10 slide in the annular groove 17 of the support 6, which improves the load-bearing capacity of the turntable 10 and the stability of the turntable 10 rotation. Through the structural setup of the parts processing mechanism, the milling cutter 16 can be controlled to move horizontally and vertically, and the milling cutter 16 can be rotated to process heavy parts. The electric slide 5 can be controlled to run on the electric slide table 4, and the heavy workpiece on the turntable 10 can be moved below the milling cutter 16 to process the workpiece.
