Description

Technical Field

[0001] This utility model relates to the field of CNC machine tool technology, specifically to a CNC machine tool machining rotary device. Background Technology

[0002] In the field of mechanical manufacturing, CNC machine tools are the core equipment for achieving high-precision and high-efficiency automated processing. With the development of intelligent manufacturing, increasingly higher requirements are being placed on the processing capabilities, processing range, and processing accuracy of CNC machine tools. Many workpieces, especially those with complex curved surfaces, asymmetrical structures, or those that need to be processed in multiple directions, often require changes in their posture or position during processing. This necessitates the use of rotary devices to adjust the angle of the clamped workpiece. Currently, rotary devices mainly use drivers to rotate the fixture within the bearing housing. The surface of the bearing housing is equipped with a lubrication structure to continuously lubricate the connection points of the bearing housing. However, most of the connection points of the lubrication structure within the rotary device lack auxiliary structures, requiring manual support during installation. When the hand slips, the lubrication structure is prone to tilting during installation, resulting in gaps. Utility Model Content

[0003] The purpose of this invention is to provide a rotary machining device for CNC machine tools to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a CNC machine tool machining rotary device, comprising a base, a bearing seat fixedly connected to the top of the base, a rotating shaft rotatably connected inside the bearing seat, a connecting plate fixedly connected to one end of the rotating shaft, a motor one provided on the left side of the base, a clamp provided above the connecting plate, a motor two provided below the connecting plate, a sleeve fixedly connected inside the bearing seat, a lubricating cylinder clamped inside the sleeve, a limit rod connected outside the lubricating cylinder, an L-shaped groove provided inside the sleeve, a sliding ring slidably connected outside the sleeve, an arc-shaped clamping plate fixedly connected above the sliding ring, and a bolt threaded inside the limit rod.

[0005] As a further preferred embodiment of this technical solution, the output shaft of motor one is connected to the connecting plate, the output shaft of motor two is connected to the clamp, and one end of the lubrication cylinder is connected to a conveying pipe.

[0006] As a further preferred embodiment of this technical solution, the limiting rod overlaps within the L-shaped groove, the arc-shaped clamping plate is clamped into the limiting rod, and the arc-shaped clamping plate is connected to the limiting rod by bolts.

[0007] As a further preferred embodiment of this technical solution, a fixing ring is fixedly connected to the outside of the sleeve, the arc-shaped clamping plate is slidably connected inside the fixing ring, and a column is fixedly connected above the moving ring.

[0008] As a further preferred embodiment of this technical solution, a fixing ring is fixedly connected to the outside of the sleeve, the arc-shaped clamping plate is slidably connected inside the fixing ring, and a fixing disc is fixedly connected to the top of the column.

[0009] As a further preferred embodiment of this technical solution, the column is fitted with a spring, the arc-shaped card plate has an installation hole, and the fixing plate is connected to the fixing ring by the spring.

[0010] This utility model provides a rotary device for CNC machine tool processing, which has the following beneficial effects:

[0011] (1) This utility model sets up an L-shaped groove, a limiting rod, a moving ring, an arc-shaped clamping plate, a limiting rod and bolts. After applying a thrust to the moving ring, the lubricating cylinder is clamped into the sleeve. The limiting rod on the surface of the lubricating cylinder will slide in the L-shaped groove. When the limiting rod overlaps the end of the L-shaped groove, the moving ring is released and the arc-shaped clamping plate will clamp into the limiting rod. Then the limiting rod is connected to the arc-shaped clamping plate by bolts. The rotating device can position the lubricating cylinder during installation by cooperating with the L-shaped groove, the limiting rod and the arc-shaped clamping plate, so as to avoid the phenomenon of the lubricating cylinder shifting during installation. There is no need to manually support the lubricating cylinder afterwards, which prevents the phenomenon of gaps after the lubricating cylinder is fixed to the sleeve, and ensures the flexibility of the rotating device.

[0012] (2) By setting a fixed plate and a spring, the present invention applies a pushing force to the moving ring, and the moving ring slides on the surface of the sleeve. The column above the moving ring slides inside the fixed ring. Then the fixed plate will drive the spring to deform, so that the fixed plate and the spring play a certain supporting role for the movement of the moving ring, and avoid the phenomenon of misalignment of the moving ring when it moves.

[0017] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0018] This utility model provides a technical solution: such as Figure 1 and Figure 3 As shown in this embodiment, a CNC machine tool machining rotary device includes a base 1, a bearing seat 2 fixedly connected above the base 1, a rotating shaft 8 rotatably connected inside the bearing seat 2, a connecting plate 3 fixedly connected to one end of the rotating shaft 8, a motor 4 on the left side of the base 1, a clamp 6 above the connecting plate 3, a motor 7 below the connecting plate 3, a sleeve 5 fixedly connected inside the bearing seat 2, a lubricating cylinder 9 clamped inside the sleeve 5, a limit rod 12 connected to the outside of the lubricating cylinder 9, an L-shaped groove 11 opened inside the sleeve 5, a moving ring 15 slidably connected to the outside of the sleeve 5, an arc-shaped clamping plate 16 fixedly connected above the moving ring 15, and a bolt 13 threadedly connected inside the limit rod 12.

[0019] like Figure 1 and Figure 2 As shown, the output shaft of motor 4 is connected to the connecting plate 3, the output shaft of motor 7 is connected to the clamp 6, one end of the lubrication cylinder 9 is connected to the conveying pipe 10, the limiting rod 12 overlaps in the L-shaped groove 11, the arc-shaped clamping plate 16 is clamped in the limiting rod 12, the arc-shaped clamping plate 16 is connected to the limiting rod 12 by bolts 13, the sleeve 5 is fixedly connected to the outside of the fixing ring 14, the arc-shaped clamping plate 16 is slidably connected in the fixing ring 14, and the moving ring 15 is fixedly connected to the top of the column 18;

[0020] By setting the L-shaped groove 11 and the limiting rod 12, when the lubricating cylinder 9 is inserted into the sleeve 5, the limiting rod 12 will slide in the L-shaped groove 11. When the lubricating cylinder 9 rotates, the limiting rod 12 will overlap the end of the L-shaped groove 11, which can play a certain limiting role in fixing the lubricating cylinder 9 and the sleeve 5, and avoid the phenomenon of collision when the lubricating cylinder 9 and the sleeve 5 are assembled.

[0021] like Figure 3As shown, a fixing ring 14 is fixedly connected to the outside of the sleeve 5, and an arc-shaped clamping plate 16 is slidably connected inside the fixing ring 14. A fixing plate 19 is fixedly connected to the top of the column 18, and a spring 20 is fitted onto the outside of the column 18. An installation hole 17 is opened inside the arc-shaped clamping plate 16, and the fixing plate 19 is connected to the fixing ring 14 through the spring 20.

[0022] By setting a fixed ring 14, when a pushing or pulling force is applied to the moving ring 15, both the column 18 and the arc-shaped clamping plate 16 slide within the fixed ring 14, so that the fixed ring 14 plays a certain guiding role in the movement of the moving ring 15, and prevents the moving ring 15 from rotating when it moves.

[0023] This utility model provides a rotary machining device for CNC machine tools, the specific working principle of which is as follows:

[0024] When the rotating device is in use, a thrust can be applied to the moving ring 15, which will slide on the surface of the sleeve 5. The column 18 above the moving ring 15 will slide within the fixed ring 14. Then, the fixed plate 19 will cause the spring 20 to deform, and then the lubrication cylinder 9 will be snapped into the sleeve 5. The limiting rod 12 on the surface of the lubrication cylinder 9 will slide within the L-shaped groove 11. When the limiting rod 12 overlaps the end of the L-shaped groove 11, the moving ring 15 will be released. When the moving ring 15 loses resistance, it will be reset by the spring 20. The arc-shaped clamping plate 16 will be snapped into the limiting rod 12. Then, the limiting rod 12 will be connected to the arc-shaped clamping plate 16 by the bolt 13.

[0025] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
