Description

Technical Field

[0001] This utility model belongs to the field of machine tool technology, and in particular relates to a structurally reinforced vertical machining center. Background Technology

[0002] In the field of machining, machining centers are key equipment for achieving high-precision and high-efficiency machining. Among them, vertical machining centers, due to their structural characteristics, are widely used in milling, drilling, boring, and other machining processes for various parts.

[0003] In traditional machining centers, the gantry, as a key component supporting and bearing the transmission mechanism and machining spindle, often adopts a single-frame structure. This single-frame structure, supported only by a single frame, has several shortcomings in actual machining processes. When the machining spindle processes the workpiece, it generates significant cutting forces, impact forces, and vibrations. Due to the insufficient support strength and stability of the single-frame structure, it is difficult to effectively resist these forces, easily leading to frame deformation and swaying.

[0004] The instability of the gantry frame directly affects the transmission accuracy of its transmission structure. When the transmission structure operates on an unstable support foundation, problems such as increased transmission error and decreased positioning accuracy will occur. Utility Model Content

Those skilled in the art can understand the specific meaning of the above terms in this embodiment of the invention according to the specific circumstances.

[0030] In one embodiment of this utility model, reference is made to Figures 1-7As shown, a structurally reinforced vertical machining center is provided, including a machine base 100, a gantry 600, a three-axis transmission mechanism 200, a machining spindle 300, and a work platform 400. The work platform 400 is disposed on the upper end of the machine base 100, the gantry 600 is fixed to the top side of the machine base 100, and the three-axis transmission mechanism 200 is disposed on the top side of the gantry 600. The gantry 600 is I-shaped. The three-axis transmission mechanism 200 is disposed on the top side of the gantry 600 and located on one side of the work platform 400. The machining spindle 300 is disposed at the drive end of the three-axis transmission mechanism 200. The work platform 400 includes a work base 410, a drive mechanism 420, and a worktable 430. The worktable 430 is slidably disposed on the upper end of the work base 410, and the drive mechanism 420 is disposed on the work base 410. The drive mechanism 420 is used to drive the worktable 430 to slide horizontally on the work base 410. The worktable 430 is provided with two processing positions 431. In this embodiment, during use, the workpieces are placed on each processing position 431 of the worktable 430. Then, the drive mechanism 420 drives the worktable 430 to slide on the work base 410, so that each processing position 431 passes the lower end of the machining spindle 300 in sequence. The machining spindle 300 processes the workpieces on the worktable 430 in sequence. After processing, the workpieces gradually move away from the machining spindle 300 as the worktable 430 moves. At this time, the operator can unload the processed workpieces. After unloading, the blank is reloaded. The drive mechanism 420 drives the worktable 430 to move in the opposite direction, so that the structurally reinforced vertical machining center equipment provided by this utility model maintains the processing state. The processing state is not affected when loading and unloading workpieces, thus improving the processing speed.

[0031] Specifically, refer to Figures 1-7 As shown, a clearance groove 411 is provided on the working base 410, and the drive mechanism 420 is disposed in the clearance groove 411. The drive mechanism 420 is located below the worktable 430.

[0032] Specifically, refer to Figures 1-7As shown, it also includes a protective mechanism 500, and the worktable 430 is provided with two processing positions 431. The protective mechanism 500 is set on the work base 410, and includes two loading boxes 510 and a transparent protective door 520. The two loading boxes 510 are located on both sides of the transparent protective door 520. In this embodiment, the worktable 430 is provided with two processing positions 431. When one processing position 431 is located inside the transparent protective door 520, the other workpiece is located in the loading box 510. While loading and unloading the workpieces in the loading box 510 are being performed, the workpieces located inside the transparent protective door 520 are being processed by the processing spindle 300. Loading and unloading the workpieces does not affect the processing status, thus improving the processing speed. At the same time, the transparent protective door 520 allows the operator to easily observe the processing status of the workpieces located below the processing spindle 300.

[0033] Specifically, refer to Figures 1-7 As shown, a lifting door 511 is provided on the side of the loading box 510 near the transparent protective door 520. The lifting door 511 is used to prevent the workpieces on the processing position 431 from being obstructed. A hinged door 512 is connected to the other side of the loading box 510. In this embodiment, when the worktable 430 is moving, the lifting door 511 opens, and when the worktable 430 stops moving, the lifting door 511 closes. The workpieces located inside the transparent protective door 520 are processed by the processing spindle 300, which can prevent iron filings or waste from splashing outside the transparent protective door 520 during processing, and prevent iron filings or waste from injuring the operator during loading and unloading.

[0034] Specifically, refer to Figures 1-7 As shown, the drive mechanism 420 includes a drive unit 421, a ball screw 422, a nut seat 423, and a tailstock 424.

The other end of the ball screw 422 is connected to the tailstock 424. The nut seat 423 is sleeved on the ball screw 422, and one end of the nut seat 423 is connected to the worktable 430. In this embodiment, using a screw drive as the drive mechanism 420 has advantages such as high transmission accuracy, smooth movement, no crawling phenomenon, and no idle stroke during reverse, thus improving machining accuracy.
