Description

Technical Field

[0002] At present, CNC lathes are mainly horizontal machines, which have the disadvantage of occupying a large area. Workers need to walk a long distance when they need to operate multiple machines, which increases the labor intensity of workers and affects work efficiency. In addition, with the tightening of land resources, the cost of processing sites is getting higher and higher, so it is hoped that the equipment can be more compact and miniaturized, so as to increase the volume ratio of the workshop.

[0003] In the prior art, there is a vertical multi-spindle CNC lathe with narrow-spacing axes, such as the announcement number CN209918898U. However, in actual use, this technical solution still has the following shortcomings:

[0024] The method for using the narrow-pitch axis vertical multi-spindle CNC lathe comprises the following steps:

[0025] S1. Workpiece positioning and clamping: Place the workpiece at the bottom center of the fixed plate, use the hexagonal wrench to rotate the drive screw, and drive the L-shaped clamping plate to move horizontally through the threaded plate to achieve workpiece positioning and clamping to ensure stable processing;

[0026] S2, support and limit: longitudinally move the support frame, use the L-shaped clamp to clamp the workpiece, and then support the cover; release the clamp rod, and the compression spring drives the clamp rod to insert into the slot, and limit the support frame and the cover;

[0032] It is to be understood that the foregoing general description and the following detailed description are exemplary only and are not restrictive of the invention.

[0033] Compared with the prior art, the present invention has the following beneficial effects:

[0034] In the present invention, the protective mechanism can effectively protect the waste chips generated during the processing after the workpiece is placed in the protective box and the two door panels are closed, preventing them from splashing around and protecting the workers. At the same time, the waste chips can fall into the collection box through the first discharge hole and the second discharge hole for easy collection.

[0035] Through the drive mechanism, the present invention can sequentially operate multiple clamping components to stably clamp the workpiece after the workpiece is placed in the center area of ​​the bottom of the fixed plate. After the drive motor is started, the fixed plate and the workpiece rotate accordingly, thereby realizing turning processing.

[0036] The limiting mechanism of the present invention allows the support frame to be moved longitudinally, and after the workpiece is clamped by multiple L-shaped clamps, the workpiece is supported by the support cover. After the two clamping rods are released, the two compression springs in a stressed state will drive the clamping rods to move and insert into the corresponding clamping slots to limit the support frame and the support cover, ensuring that the workpiece is stably supported.

[0037] In terms of the processing mechanism, when the driving motor of the present invention is working, the transmission shaft is driven to rotate through the transmission cooperation of two synchronous wheels and a synchronous belt. Under the transmission cooperation of two slideways and the corresponding second slide plate, the rotating ring and the bevel gear ring rotate accordingly. After meshing with the bevel gear, the driving shaft rotates, and then the cutter head clamped on the cutter cover is driven to rotate through the moving tube and the cutter cover. In this way, while driving the workpiece to rotate, the cutter head also rotates synchronously to process the workpiece. In particular, when milling grooves on the workpiece, the pressure on the workpiece can be reduced to avoid bending of the workpiece.

[0038] In addition, the present invention also provides a moving mechanism, which drives the two adjusting screws to rotate by starting the power assembly. Under the threaded transmission action of the corresponding threaded holes, the moving plate moves longitudinally, thereby adjusting the height of the cutter head, so as to perform turning processing on different positions of the workpiece, making the processing process more convenient.

[0039] In summary, after the workpiece is clamped and positioned, the present invention can ensure that the workpiece is turned in a relatively closed space to prevent waste chips from flying around, and drive the cutter head to rotate during the processing to reduce the pressure on the workpiece and avoid deformation of the workpiece.

The moving mechanism is installed on the protective mechanism and connected to the processing mechanism to adjust the position of the processing mechanism to meet the processing requirements of different workpieces. The specific installation and connection methods of these mechanisms need to be determined according to the specific design and processing requirements of the lathe, but it should be ensured that they can work together to achieve accurate processing of the workpiece.

[0062] The processing mechanism is designed in detail and installed in the protective box 3. The transmission shaft 17 is rotatably connected to the bottom of the protective box 3 through bearings, and slide grooves 20 are symmetrically provided on both sides thereof.

[0065] Example 2

[0066] Reference Fig.11 , based on the improvement of the first embodiment: a vertical multi-spindle CNC lathe with narrow pitch axes, further proposes a moving mechanism, which is designed as follows: the inner wall at the bottom of the protection box 3 is symmetrically rotated to connect two adjusting screws 35, whose thread directions are opposite.

[0070] S1. After placing the workpiece in the bottom center area of ​​the fixed plate 16, insert the hexagonal wrench matching the hexagonal nut 44 into the hexagonal nut 44 in turn, and then rotate the drive screw 43. At this time, under the threaded transmission action of the threaded plate 45, the L-shaped clamping plate 46 can be driven to move horizontally, and the workpiece can be positioned and clamped. When processing the workpiece, multiple L-shaped clamping plates 46 can be used to clamp the workpiece, and the workpiece can be stably transmitted;

[0071] S2, the longitudinally movable support frame 10 can use the support cover 11 to support the workpiece after the workpiece is clamped by multiple L-shaped clamps 46, and then the two clamping rods 13 can be released in sequence.

[0072] S3, after fixing the workpiece in the protection box 3, and then closing the two door panels 4, the waste chips generated during the processing of the workpiece can be protected, so as to prevent the waste chips from splashing around and protect the workers. When the workpiece is processed, the waste chips generated can fall into the collection box 2 through the first discharge hole 40 and the second discharge hole 41, so that the waste chips can be conveniently collected;

[0073] S4, when the driving motor 15 is started to drive the fixed plate 16 to rotate, the workpiece can be driven to rotate;

[0074] S5. When the driving motor 15 is working, the transmission shaft 17 can be driven to rotate through the transmission cooperation of the two synchronous wheels 18 and the synchronous belt 19. At this time, the rotating ring 22 can be driven to rotate under the transmission cooperation of the two slide grooves 20 and the corresponding second slide plate 23, which can drive the bevel gear ring 24 to rotate. At this time, under the meshing transmission action with the bevel gear 27, the driving shaft 26 can be driven to rotate, and the tool head clamped on the tool cover 29 can be driven to rotate through the moving tube 28 and the tool cover 29. At this time, the tool head can be driven to rotate synchronously with the workpiece being driven to rotate, so that the tool head can be rotated when the workpiece is processed, and the pressure on the workpiece can be reduced when the groove is milled on the workpiece to avoid the problem of bending of the workpiece;

[0075] S6. The mounting plate 32 is driven to move horizontally by starting the electric push rod 34. At this time, the two transmission rods 31 can be driven to move. That is, the moving tube 28 can be driven to move under the drive of the connecting plate 30, and the cutter head can be driven to approach the workpiece, so that the workpiece can be conveniently machined;

[0076] S7. Start the stepper motor 37 to drive the driving gear 38 to rotate. At this time, under the meshing transmission action with the two driven gears 39, it can drive the two adjusting screws 35 to rotate. At this time, under the threaded transmission action with the corresponding threaded holes, it can drive the movable plate 21 to move longitudinally, so that the height of the tool head can be adjusted, so that turning processing can be performed on different positions of the workpiece, making it more convenient to process the workpiece.

[0077] However, as is well known to those skilled in the art, the working principles and wiring methods of the drive motor 15, the electric push rod 34 and the stepper motor 37 are commonplace, and are conventional means or common knowledge, and will not be elaborated here. Those skilled in the art can make any selections according to their needs or convenience.

Any person skilled in the art can easily think of changes or substitutions within the technical scope disclosed by the present invention, which should be included in the protection scope of the present invention; the embodiments of the present invention and the features in the embodiments can be combined with each other without conflict.
