[0002] Existing vertical machining centers have a worktable in the machining area for fixing workpiece trays and use a vertical machining mechanism to process the workpieces. The workpiece trays are used to clamp the workpieces. Currently, most vertical machining centers use manual labor for workpiece loading and unloading, while a few vertical machining centers use robotic arms for workpiece clamping and unloading.

[0003] However, since the workbench is located in the machining area of ​​the vertical machining center, the vertical machining center cannot process another workpiece simultaneously while one workpiece is being disassembled or assembled, which affects production efficiency.

[0004] In view of the above problems, it is necessary to study a vertical machining center with an exchange table, which can realize the simultaneous machining and disassembly of workpieces, thus helping to improve production efficiency. Utility Model Content

[0008] The workpiece tray is provided with a bent tray hook; the push-pull seat has a push-pull hook part for vertically engaging with the tray hook, and the push-pull hook part can be horizontally positioned and engaged with the workpiece tray.

[0009] The exchange station has two push-pull mechanisms, which are arranged symmetrically at the center.

[0010] The workpiece tray has a tray through groove with an opening on the lower side, and limiting through grooves are formed on both sides of the tray through groove; the pressure plate has two limiting edges for sliding engagement with the limiting through grooves on both sides of the tray through groove.

[0048] Vertical machining mechanism 4. Detailed Implementation

[0049] To further explain the technical solution of this utility model, the following detailed description is provided through specific embodiments.

[0050] like Figures 1 to 13 As shown, this utility model discloses a vertical machining center with an exchange table, which includes a workbench 1 and an exchange table 2 for exchanging workpiece trays 3, and a vertical machining mechanism 4 for machining workpieces. The workpiece trays 3 are used to clamp workpieces. The workbench 1 is located in the machining area of ​​the vertical machining mechanism 4, while the exchange table 2 is located adjacent to the workbench 1 but outside the machining area of ​​the vertical machining mechanism 4.

[0051] Because the cooperation of the worktable 1 and the exchange table 2 of this utility model enables the exchange of two workpiece trays 3 between the worktable 1 and the exchange table 2, and the worktable 1 is located in the processing area of ​​the vertical machining mechanism 4, while the exchange table 2 is located outside the processing area of ​​the vertical machining mechanism 4; thus, when the vertical machining center with the exchange table of this utility model is working, the vertical machining mechanism 4 processes the workpieces clamped on the workpiece trays 3 on the worktable 1, and simultaneously, the workpieces that have been processed are disassembled and the workpieces to be processed are clamped on the workpiece trays 3 on the exchange table 2 by manual labor or a robotic arm; subsequently, the workpieces on the worktable 1... After the workpiece clamped on the workpiece tray 3 is processed, the worktable 1 and the exchange table 2 exchange their respective workpiece trays 3, so that the workpiece tray 3 on the exchange table 2 is transferred to the worktable 1, and the workpiece tray 3 on the worktable 1 is transferred to the exchange table 2. This allows the processed workpiece to be transferred to the exchange table 2 and the workpiece to be processed to be transferred to the worktable 1. Next, the vertical machining mechanism 4 processes the workpiece clamped on the workpiece tray 3 on the worktable 1, while simultaneously, the processed workpiece is disassembled and the workpiece to be processed is clamped on the workpiece tray 3 on the exchange table 2 by manual labor or a robotic arm. As can be seen from the foregoing, this utility model, through the cooperation of the worktable 1 and the exchange table 2, enables a vertical machining center with an exchange table to simultaneously perform workpiece processing and disassembly / assembly, which helps to improve production efficiency.

[0052] In an embodiment of this utility model, the worktable 1 may include a rotatable rotary seat 11, a height-adjustable pressure plate 12 fitted on the upper side of the rotary seat 11, a lifting drive device 13 for driving the pressure plate 12 to rise and fall, and a rotation drive device 14 for driving the rotary seat 11, the pressure plate 12, and the lifting drive device 13 to rotate. The rotation drive device 14 drives the workpiece tray 3 and the workpiece to rotate through the rotary seat 11, enabling the machining center to perform multi-directional machining on the workpiece. The pressure plate 12 is used to slide horizontally with the workpiece tray 3 to restrict the relative movement of the workpiece tray 3. The pressure plate 12 moves up and down. The rotary seat 11 is provided with at least two positioning pins 111 for vertically engaging with the workpiece tray 3, thereby restricting the workpiece tray 3 from rotating and translating relative to the rotary seat 11. The exchange table 2 includes a rotatable rotary seat 21, at least two push-pull mechanisms 22 that engage with the rotary seat 21, and a rotary drive device 23 that drives the rotary seat 21 to rotate. The push-pull mechanism 22 includes a push-pull seat 221 and a push-pull drive device 222 that drives the push-pull seat 221 to translate. The push-pull seat 221 can engage vertically with the workpiece tray 3.

[0053] To facilitate understanding of this utility model, the working principle of the worktable 1 and the exchange table 2 for exchanging workpiece trays 3 is described in detail below:

[0054] First, the lifting drive device 13 of the worktable 1 drives the pressure plate 12 to move the workpiece tray 3 upward, so that the workpiece tray 3 is disengaged from the positioning pin 111 on the rotary seat 11, and the workpiece tray 3 is higher than the push-pull seat 221.

[0055] In the second step, the push-pull drive device 222 of an empty push-pull mechanism 22 (hereinafter referred to as the push-pull mechanism 22 for picking up workpieces) of the exchange table 2 drives the push-pull seat 221 of the push-pull mechanism 22 for picking up workpieces to move horizontally to below the workpiece tray 3.

[0056] Third step, the lifting drive device 13 of the workbench 1 drives the pressure plate 12 of the drive device to move the workpiece tray 3 down to the workpiece tray 3 and the push-pull seat 221 of the push-pull mechanism 22 for picking up the workpiece is inserted and engaged.

[0057] Fourth step, the push-pull drive device 222 of the push-pull mechanism 22 for picking up the workpiece drives the push-pull seat 221 of the push-pull mechanism 22 for picking up the workpiece to move the workpiece tray 3 to the rotating seat 21 of the exchange table 2.

[0058] Fifth step, the rotating seat 21 of the rotary drive device 23 of the exchange table 2 rotates to a push-pull mechanism 22 (hereinafter referred to as the push-pull mechanism 22 for placing workpieces) of the exchange table 2 that is equipped with a workpiece tray 3 and is opposite to the worktable 1.

[0059] The sixth step is that the push-pull drive device 222 of the push-pull mechanism 22 for placing the workpiece drives the push-pull seat 221 of the push-pull mechanism 22 for placing the workpiece to move the workpiece tray 3 to slide into contact with the pressure plate 12.

[0060] Step 7: The lifting drive device 13 of the worktable 1 drives the pressure plate 12 to move the workpiece tray 3 up until the workpiece tray 3 is separated from the push-pull seat 221.

[0061] Step 8: The push-pull drive device 222 of the push-pull mechanism 22 for placing the workpiece drives the push-pull base 221 of the push-pull mechanism 22 for placing the workpiece to translate and reset.

[0062] In the ninth step, the lifting drive device 13 of the worktable 1 drives the pressure plate 12 to move the workpiece tray 3 down to engage with the positioning pin 111 on the rotary seat 11.

Each set of guide rails 24 includes two guide rails 24 with guide edges 241. The guide edges 241 of the two guide rails 24 in each set of guide rails 24 are used to slide with the limiting through grooves 311 on both sides of the tray through groove 31 respectively. The top surface of the guide edge 241 of the guide rail 24 can be fitted with an upper guide wheel 242 for sliding with the inner top surface of the limiting through groove 311.
