Description

Technical Field

[0001] The utility model relates to the technical field of numerical control machining, and specifically, to a double-spindle vertical machining center with adjustable spindle spacing. Background Technique

[0002] A double-spindle vertical machining center is a special numerical control machine tool with two vertically arranged spindles, which can perform two independent machining operations simultaneously. This kind of machine tool is mainly used to improve production efficiency by machining two different workpieces simultaneously or performing multi-sided machining on a single large workpiece. Double-spindle vertical machining centers are widely used in fields that require mass production and high-precision machining, such as mold manufacturing and the production of complex components. The design of this kind of machine tool aims to optimize the production process, reduce machining time, and improve the overall working efficiency.

[0003] For example, Chinese Patent CN213858374U discloses a double-spindle vertical machining center, which includes a first spindle, a second spindle, a spindle mounting box body, a base, feet, a base cavity, and a driver. When this double-spindle vertical machining center works, the cutting tool is driven by the high-speed rotation of the first spindle and the second spindle to machine the workpiece. However, both the first spindle and the second spindle are of fixed design, so the spacing between the spindles cannot be adjusted according to workpieces of different sizes or shapes, which not only limits the machining range of this vertical machining center but also reduces the machining production efficiency.

[0021] To further illustrate each embodiment, the present utility model provides accompanying drawings. These drawings are a part of the disclosure of the present utility model, mainly used to illustrate the embodiments, and can be combined 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.

[0022] According to an embodiment of the present utility model, a double-spindle vertical machining center with adjustable spindle spacing is provided.

[0023] Now, the present utility model will be further described in conjunction with the accompanying drawings and specific implementation manners. As Figures 1 - 5 shown, the double-spindle vertical machining center with adjustable spindle spacing according to an embodiment of the present utility model includes a processing support base one 1. A longitudinal adjustment mechanism 2 is provided at the inner top of the processing support base one 1. A processing support base two 3 is provided at the top of the longitudinal adjustment mechanism 2. A transverse adjustment mechanism 4 is provided at the inner top of the processing support base two 3. A workpiece processing table 5 is provided at the top of the transverse adjustment mechanism 4. One end of the top of the processing support base one 1 is provided with a vertical processing support base 6. A vertical adjustment mechanism 7 is provided on the outer side wall of the vertical processing support base 6. Spindles 8 are symmetrically provided outside the vertical adjustment mechanism 7. A workpiece processing head 10 is provided at the bottom end of the spindle 8. The vertical adjustment mechanism 7 and the spindle 8 are connected through a spindle adjustment mechanism 9. One end of the outside of the processing support base one 1 is provided with a controller 11.

[0024] With the above solution, the utility model can perform multi-directional machining on large workpieces by using two independent spindles 8 in cooperation with the workpiece machining head 10. Thus, the parallel machining ability of the double-spindle vertical machining center is improved through the design of the double spindles 8, significantly enhancing the production efficiency and machining speed. At the same time, in cooperation with the use of the spindle adjustment mechanism 9, the distance between the two spindles can be adjusted according to the size, shape of the workpiece and machining requirements, enabling the machining center to handle a wider range of machining tasks, and further enhancing the machining flexibility.

[0025] Specifically, the double-spindle vertical machining center is equipped with two vertically arranged spindles 8. The vertical layout of the spindles 8 helps to utilize gravity to promote the discharge of chips, reduce the accumulation in the cutting area, and maintain a clean machining environment. This enables it to perform multiple operations at the same time, greatly improving the production efficiency. Moreover, the vertical design makes the floor area of the machine tool relatively small, suitable for environments with limited working space.

[0026] In one embodiment, for the above longitudinal adjustment mechanism 2, the longitudinal adjustment mechanism 2 includes a driving motor one 201 arranged on the outer side of one side of the machining support base 1. The output end of the driving motor one 201 penetrates through the machining support base 1 and is connected to a lead screw one 202. A slider one 203 is sleeved on the outer circumference of the lead screw one 202, and a machining support base two 3 is arranged at the top end of the slider one 203. The transverse adjustment mechanism 4 includes a driving motor two 401 arranged on the outer side of one side of the machining support base two 3. The output end of the driving motor two 401 penetrates through the machining support base two 3 and is connected to a lead screw two 402. A slider two 403 is sleeved on the outer circumference of the lead screw two 402, and a workpiece machining table 5 is arranged at the top end of the slider two 403. The vertical adjustment mechanism 7 includes a driving motor three 701 arranged at the top of the vertical machining support base 6. The output end of the driving motor three 701 penetrates through the vertical machining support base 6 and is connected to a lead screw three 702. A slider three 703 is sleeved on the outer circumference of the lead screw three 702, and a connecting moving plate 704 is arranged outside the slider three 703. Thus, through the three-dimensional adjustment ability, the double-spindle vertical machining center can process a wide range of workpieces from small precision parts to large structural parts, and at the same time, accurately adjust the position of the workpiece, enabling the double-spindle vertical machining center to adapt to workpieces of various sizes and shapes.

[0027] It should be noted that the working principle of the cooperation between the longitudinal adjustment mechanism 2 and the transverse adjustment mechanism 4 is as follows:

[0028] The drive motor 201 is started by the controller 11. The output shaft of the drive motor 201 drives the lead screw 202 to rotate. While the lead screw 202 rotates, it drives the slider 203 to move longitudinally. At the same time, the slider 203 drives the machining support base 3 to move longitudinally, thereby realizing the longitudinal movement of the workpiece processing table 5. The drive motor 401 is started by the controller 11. The output shaft of the drive motor 401 drives the lead screw 402 to rotate. While the lead screw 402 rotates, it drives the slider 403 to move transversely, thereby realizing the longitudinal movement of the workpiece processing table. Under the combined action of the longitudinal adjustment mechanism 2 and the transverse adjustment mechanism 4, the workpiece processing table 5 can be accurately positioned.

[0029] The working principle of the vertical adjustment mechanism 7 is as follows: The drive motor 701 is started by the controller 11. The output shaft of the drive motor 701 drives the lead screw 702 to rotate. While the lead screw 702 rotates, it drives the slider 703 to move longitudinally. At the same time, the slider 703 drives the connecting moving plate 704 to move longitudinally, thereby realizing the height adjustment of the workpiece processing head 10.

[0030] In one embodiment, for the above-mentioned spindle adjustment mechanism 9, the spindle adjustment mechanism 9 includes a machining support base 901 provided on one side of the connecting moving plate 704. A fixed connecting plate 902 is provided at the top of the machining support base 901. A spindle spacing adjustment mechanism 903 is provided at the bottom end of the fixed connecting plate 902. A spindle drive mechanism 904 is provided at the bottom end of the spindle spacing adjustment mechanism 903. A spindle 8 is provided at the bottom of the spindle drive mechanism 904. A connecting bracket 905 that cooperates with the machining support base 901 is sleeved outside the spindle drive mechanism 904. The spindle spacing adjustment mechanism 903 includes a cylinder 9031 provided on one side of the bottom of the fixed connecting plate 902. A rack 9032 is provided at the output end of the cylinder 9031. A gear 9033 is provided on one side of the rack 9032. Rack 9034s are provided at both outer ends of the gear 9033. Adjusting plates 9036 are provided at one end of each of the rack 9034s. Bases 9037 are provided around the fixed connecting plate 902. Sliding grooves 9038 that cooperate with the sliding plates 9035 are provided inside the bases 9037, so that the distance between the two spindles can be adjusted according to the size and shape of the workpiece and the processing requirements, enabling the machining center to handle a wider range of machining tasks, thereby improving the flexibility of machining.

[0031] Specifically, the working principle of the main shaft adjusting mechanism 9 is as follows: When the connecting moving plate 704 moves, it drives the third machining support base 901 to adjust its height, so that the workpiece machining head can be adjusted. At the same time, the air cylinder 9031 is started by the controller 11, and the output end of the air cylinder 9031 drives the first rack 9032 to move. When the first rack 9032 moves, it drives the gear 9033 to rotate. The gear 9033 drives two meshing second racks 9034 to move relatively, and at the same time drives the slide plate 9035 to move in the chute 9038, so as to realize the relative movement of the two adjusting plates 9036, and further realize the adjustment of the distance between the main shafts 8. Furthermore, the distance between the two main shafts 8 can be adjusted according to the size and shape of the workpiece and the processing requirements, so that the machining center can handle a wider range of machining tasks.

[0032] To facilitate the understanding of the above technical solutions of the present invention, the working principle or operation method of the present invention in the actual process will be described in detail below.

[0033] In actual application, when machining a workpiece, first start the longitudinal adjusting mechanism 2, the transverse adjusting mechanism 4 and the vertical adjusting mechanism 7. Under the combined action of the longitudinal adjusting mechanism 2, the transverse adjusting mechanism 4 and the vertical adjusting mechanism 7 (the working principles of the longitudinal adjusting mechanism 2, the transverse adjusting mechanism 4 and the vertical adjusting mechanism 7 are as shown above), the precise alignment of the two workpiece machining heads and the workpiece machining table can be achieved. At the same time, combined with the use of the main shaft adjusting mechanism 9 (the working principle of the main shaft adjusting mechanism 9 is as shown above), the distance between the two main shafts 8 is adjusted according to the size and shape of the workpiece and the processing requirements, so that the machining center can handle a wider range of machining tasks, and further improve the flexibility of machining.

[0034] In summary, with the above technical solutions of the present invention, the double-spindle vertical machining center provided by the present invention can perform multi-directional machining on large workpieces through two independent main shafts 8 in cooperation with the workpiece machining head 10. Thus, the parallel machining ability of the double-spindle vertical machining center is improved through the design of the double main shafts 8, significantly improving the production efficiency and machining speed. At the same time, combined with the use of the main shaft adjusting mechanism 9, the distance between the two main shafts 8 can be adjusted according to the size and shape of the workpiece and the processing requirements, so that the machining center can handle a wider range of machining tasks, and further improve the flexibility of machining; under the combined action of the longitudinal adjusting mechanism 2, the transverse adjusting mechanism 4 and the vertical adjusting mechanism 7 of the present invention, the double-spindle vertical machining center can process a wide range of workpieces from small precision parts to large structural parts through three-dimensional adjustment ability, and at the same time realize precise adjustment of the workpiece position, so that the double-spindle vertical machining center can adapt to workpieces of various sizes and shapes, providing a high degree of machining flexibility.
