DETAILED DESCRIPTION

[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] The utility model provides Figure 1-9 The high-precision double-exchange worktable machining center shown in the figure includes a machine tool 13, a rotating plate 1 is arranged on one side of the machine tool 13, and worktables 2 are symmetrically arranged on both sides of the rotating plate 1. A limiting component 3 for connecting the rotating plate 1 and the worktable 2 is arranged at the connection between the rotating plate 1 and the worktable 2. The limiting component 3 includes a limiting block 301 arranged on one side of the worktable 2, and a power component is arranged at the bottom of the rotating plate 1; a connecting block 4 is fixedly connected to the center of one side of the worktable 2 symmetrically, and a hole for the connecting block 4 to penetrate the limiting block 301 is symmetrically opened on one side of the limiting block 301. The connecting groove 5 of the control block 301, the inner wall of one side of the connecting groove 5 is interspersed with a clamping block 6 for limiting the movement of the connecting block 4, one side of the clamping block 6 is provided with a moving component 7 for driving the clamping block 6 to move, the limiting component 3 also includes a moving block 302 symmetrically fixedly connected to both sides of the rotating plate 1, one side of the moving block 302 is provided with a limiting groove 303 adapted to the limiting block 301, the limiting block 301 is interspersed and connected inside the limiting groove 303, the middle part of the connecting block 4 is provided with a clamping groove 8, the clamping block 6 is interspersed and connected inside the clamping groove 8.

[0028] It should be noted that the machine tool 13 is a horizontal machining center of model TH630S; the limiting block 301 is composed of a square block and blocks with trapezoidal cross-sections on both sides of the square block, and the limit groove 303 is composed of a square groove and a trapezoidal groove. When in use, the limiting block 301 is inserted into the inside of the limiting groove 303. When in use, the trapezoidal design makes it impossible for the limiting block 301 located in the limiting groove 303 to move out of the limiting groove 303 in the direction except the top of the limiting groove 303. Therefore, when the workbench 2 needs to be moved, the moving block 302 is driven to move upward by the moving assembly 7. The moving block 302 is moved so that it is sleeved on the bottom of the limiting block 301 and is moved by the limiting assembly 7. The groove 303 is used to limit the position of the limiting block 301, and the limiting block 301 and the workbench 2 are continued to be moved upward by the moving block 302, and the rotating plate 1 and the workbench 2 are driven to rotate by the moving component 7, so that the two workbenches 2 are exchanged; the opened connecting groove 5 is adapted to the provided connecting block 4, and is used to insert the connecting block 4 into the interior of the connecting groove 5 when in use, and when the connecting block 4 needs to be fixed inside the connecting groove 5, the moving component 7 is used to drive the clamping block 6 to move into the clamping groove 8 on the connecting block 4, and the connecting block 4 is restricted inside the connecting groove 5 by the clamping block 6, so that the connecting block 4 cannot be moved out of the connecting groove 5, thereby completing the fixation between the limiting block 301 and the workbench 2.

[0029] Specifically, the moving component 7 includes a driving block 701 arranged at one end of the card block 6, a spring 702 is arranged on the side of the driving block 701 away from the card block 6, a penetration block 703 is arranged on the top of the driving block 701, and a blocking block 704 is fixedly connected to the top of the penetration block 703, a cavity 9 is symmetrically opened in the middle center of the limiting block 301, the driving block 701 and the spring 702 are both inserted and connected inside the cavity 9, an insertion hole is opened on the inner wall at the top of the cavity 9, and the penetration block 703 is inserted and connected inside the insertion hole.

[0030] It should be noted that the driving block 701 is adapted to the cavity 9, and the horizontal longitudinal cross-sections of both are square. When the driving block 701 moves in the cavity 9, the driving block 701 is prevented from rotating in the cavity 9. One end of the spring 702 is fixedly connected to the inside of one side of the cavity 9, and the other end is fixedly connected to the driving block 701. When in use, it is used to push the driving block 701 to one side of the card block 6. A spring is provided on one side of the cavity 9 for the card block 6 to pass through the cavity 9. The hole in the cavity 9 has a horizontal longitudinal section that is smaller than the horizontal longitudinal section of the driving block 701, so as to prevent the driving block 701 from passing through the hole and out of the cavity 9. The through hole and the through block 703 are used to connect the driving block 701 in the cavity 9 and the blocking block 704 outside the cavity 9. When in use, the driving block 701 in the cavity 9 is moved by the blocking block 704. When in use, the through hole is blocked by the blocking block 704, so as to prevent debris from entering the cavity 9.

[0031] Specifically, the power assembly includes a rotating shaft 10 inserted and connected in the middle of the rotating plate 1, a cam exchange mechanism 11 is arranged at the bottom end of the rotating shaft 10, bases 12 are symmetrically arranged on both sides of the rotating plate 1, and the workbench 2 is arranged on the top of the base 12.

[0032] It should be noted that the cam exchange mechanism 11 is a work exchange table with model SPC40, and the rotating shaft 10 is fixed at the output end of the cam exchange mechanism 11. When in use, the rotating shaft 10 and the rotating plate 1 are driven to move up and down and rotate through the cam exchange mechanism 11; four grooves for limiting the movement of the workbench 2 are symmetrically provided at the bottom center of the workbench 2, and rods that are compatible with the grooves at the bottom of the workbench 2 are symmetrically provided at the top center of the base 12. When the position of the workbench 2 needs to be limited, the rod is inserted into the groove at the bottom of the workbench 2, and the position of the workbench 2 is fixed by the rod and the groove.

[0033] Finally, it should be noted that the above is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments or to make equivalent substitutions for some of the technical features therein.
