[0012] 1. The structure of the utility model is reasonable and reliable, and the operation is simple. The workpiece is placed and fixed on the jigs on both sides of the T-shaped placement plate. Then, under the action of the triaxial vertical machining assembly and the moving column, the two spindles can be driven to move in three directions of the X-axis, Y-axis, and Z-axis, so as to machine the workpiece on the jig on one side of the T-shaped placement plate in multiple directions through the spindle. When the workpiece on the jig on one side is machined, under the action of the rotating assembly, the rotation of the T-shaped placement plate can be realized, driving the T-shaped placement plate to rotate 180 degrees.

The rotation of the servo motor two drives the rotation of the screw rod two. Then, under the action of the slide bar one, the sliding plate moves in the X-axis direction. The movement of the sliding plate drives the movement of the moving frame, driving the spindle to move in the X-axis direction. When it is necessary to make the spindle move in the Y-axis direction, the servo motor one is started to rotate. The rotation of the servo motor one drives the rotation of the screw rod one. Under the action of the screw rod one, the moving column is driven to move. Under the action of the moving column, the spindle is driven to move in the Y-axis direction. When it is necessary to drive the spindle to move in the Y-axis direction, the servo motor three is started to drive the rotation of the screw rod three. The rotation of the screw rod three drives the moving column to move in the Z-axis direction under the action of the slide bar two. Under the action of the moving column, the two spindles are driven to move in the Z-axis direction, so that the two spindles can machine the workpiece in three directions of the X-axis, Y-axis, and Z-axis, thereby improving the machining accuracy of the moving-column type double-spindle machining center and increasing the production efficiency.

They are mainly used to illustrate the embodiments and can cooperate with the relevant descriptions in the specification to explain the operating principle of the embodiments. With reference to these contents, those of ordinary skill in the art should be able to understand other possible implementation manners and the advantages of the present utility model. The components in the drawings are not drawn to scale, and similar component symbols are usually used to represent similar components.

[0025] According to an embodiment of the present utility model, a moving-column type double-spindle machining center is provided.

[0026] Now, the present utility model will be further described in conjunction with the attached drawings and specific implementation manners. As Figures 1-6 shown, the moving-column type double-spindle machining center according to an embodiment of the present utility model includes a base 1. A rotating assembly 2 is disposed through the bottom of the base 1. The top of the rotating assembly 2 is connected to a T-shaped placement plate 3. A plurality of fixtures 4 are symmetrically arranged on both sides of the T-shaped placement plate 3. A three-axis vertical machining assembly 5 that cooperates with the T-shaped placement plate 3 is disposed on the top of the base 1. A moving column 6 is disposed on one side of the three-axis vertical machining assembly 5. Spindles 7 are symmetrically arranged at the top of the moving column 6. In specific applications, in order to avoid interference due to too small a distance between the two spindles 7, the distance between the two spindles 7 is twice the distance between adjacent fixtures 4. A control panel 8 is disposed on one side of the base 1.

[0027] In addition, the working principles and structures of the hydraulic telescopic rod 202, the fixture 4, the first servo motor 503, the second servo motor 507, the twelfth servo motor 5012, and the spindle 7 are all prior arts, and will not be elaborated here.

[0028] In one embodiment, for the above-mentioned rotating assembly 2, the rotating assembly 2 includes a housing 201 disposed at the bottom of the base 1. A hydraulic telescopic rod 202 is disposed inside the housing 201. The telescopic end of the hydraulic telescopic rod 202 is connected to a rack 203. A gear 204 is meshed on one side of the rack 203. A rotating shaft 205 connected to the T-shaped placement plate 3 is disposed in the middle of the top of the gear 204. Thus, under the action of the rotating assembly 2, the rotation of the T-shaped placement plate 3 can be realized. Then, driven by the rotating shaft 205, the T-shaped placement plate 3 can be rotated by 180 degrees, enabling the staff to install the workpiece and process the installed workpiece at the same time, thereby improving the processing efficiency of the moving-column type double-spindle machining center and having a wider applicability.

[0029] The specific working principle of the rotating component 2 is as follows: When it is necessary to rotate the T-shaped placement plate 3, the telescopic end of the hydraulic telescopic rod 202 extends. Under the action of the extension of the telescopic end of the hydraulic telescopic rod 202, the rack 203 is driven to move. Under the action of the movement of the rack 203, the gear 204 is driven to rotate. The rotation of the gear 204 drives the rotation of the rotating shaft 205. Under the action of the rotation of the rotating shaft 205, the T-shaped placement plate 3 can be driven to rotate by 180 degrees. At this time, the two sides of the T-shaped placement plate 3 can be swapped, and thus the staff can install the workpiece and process the installed workpiece at the same time, improving the processing efficiency of the moving column type double-spindle machining center.

[0030] In one embodiment, for the above-mentioned three-axis vertical machining component 5, the three-axis vertical machining component 5 includes fixed seats 501 arranged on the side walls at both ends of the base 1. Chutes 502 are provided at the tops of the fixed seats 501. A first servo motor 503 is respectively arranged through one side wall of each fixed seat 501. The output ends of the first servo motors 503 are respectively connected with first threaded rods 504 located inside the chutes 502. Moving columns 505 are sleeved on the circumferences of the first threaded rods 504. A first sliding rod 506 is symmetrically arranged between the tops of the two moving columns 505. A second servo motor 507 is arranged through one side wall at one end of the top of one of the moving columns 505. The output end of the second servo motor 507 is connected with a second threaded rod 508 located between the two first sliding rods 506. A sliding plate 509 is sleeved on the circumferences of the second threaded rod 508 and the first sliding rod 506. A moving frame 5010 is arranged on one side of the sliding plate 509. Second sliding rods 5011 are symmetrically arranged inside the moving frame 5010. A third servo motor 5012 is arranged through the top of the moving frame 5010. The output end of the third servo motor 5012 is connected with a third threaded rod 5013 located between the two second sliding rods 5011. And the moving column 6 is sleeved on the circumferences of the second sliding rods 5011 and the third threaded rod 5013. So that under the action of the three-axis vertical machining component 5, the two main shafts 7 can be driven to move in three directions of the X-axis, Y-axis and Z-axis, and thus the workpiece on the fixture 4 can be processed in multiple directions through the main shafts 7, further improving the machining accuracy of the moving column type double-spindle machining center and improving the production efficiency.

[0031] It should be noted that a first threaded hole matching the first threaded rod 504 is provided on one side wall at the bottom of the moving column 505, a second threaded hole matching the second threaded rod 508 is provided on one end side wall of the sliding plate 509, and a third threaded hole matching the third threaded rod 5013 is provided on one side at the top of the moving column 6. The first threaded hole, the second threaded hole and the third threaded hole are all prior arts and are not shown in the figure.

[0032] The specific working principle of the three-axis vertical machining assembly 5 is as follows: When it is necessary to drive the main shaft 7 to perform multi-directional machining on the workpiece, when it is necessary to drive the main shaft 7 to move in the X-axis direction, start the second servo motor 507 to rotate. The rotation of the second servo motor 507 drives the second threaded rod 508 to rotate. Then, under the action of the first slide bar 506, the rotation of the second threaded rod 508 causes the sliding plate 509 to move in the X-axis direction. The movement of the sliding plate 509 drives the movement of the moving frame 5010, which in turn drives the main shaft 7 to move in the X-axis direction. When it is necessary to make the main shaft 7 move in the Y-axis direction, start the first servo motor 503 to rotate. The rotation of the first servo motor 503 drives the first threaded rod 504 to rotate. Under the action of the first threaded rod 504, the moving column 505 is driven to move. Under the action of the moving column 505, the main shaft 7 is driven to move in the Y-axis direction. When it is necessary to drive the main shaft 7 to move in the Y-axis direction, start the third servo motor 5012 to drive the third threaded rod 5013 to rotate. Under the action of the second slide bar 5011, the rotation of the third threaded rod 5013 drives the moving column 6 to move in the Z-axis direction. Under the action of the moving column 6, the two main shafts 7 are driven to move in the Z-axis direction. Thus, the two main shafts 7 can be driven to machine the workpiece in the three directions of the X-axis, Y-axis, and Z-axis, thereby improving the machining accuracy of the moving-column type double-spindle machining center and enhancing the production efficiency.

[0033] To facilitate the understanding of the above technical solution of the present invention, the working principle or operation method of the present invention in the actual process will be described in detail below.

[0034] In actual application, first, place the workpiece to be machined in the fixtures 4 on both sides of the T-shaped placement plate 3. Then, start the three-axis vertical machining assembly 5 through the control panel 8 to drive the two main shafts 7 to machine the workpiece on the fixture 4 on one side of the T-shaped placement plate 3 in the three directions of the X-axis, Y-axis, and Z-axis. After the machining is completed, start the rotating assembly 2 through the control panel 8 to drive the T-shaped placement plate 3 to rotate 180 degrees, so that the two main shafts 7 machine the workpiece on the fixture 4 on the other side of the T-shaped placement plate 3. Then, the operator can remove the machined workpiece and install a new workpiece while the two main shafts 7 machine the workpiece on the other side of the fixture 4. Repeat the above operations, thereby improving the machining efficiency of the moving-column type double-spindle machining center and having a wider applicability.
