Description

Technical Field

[0001] The present invention relates to the technical field of machining, and particularly to a numerically controlled intelligent workbench with a positioning function and multi-angle rotation. Background Technique

[0002] A numerically controlled intelligent workbench is a common workbench in industrial machining. It mainly consists of an external computer, a numerical control device, an internal servo system, and a workbench. It is an important part of modern machining. During the machining process, the workpiece is placed on the workbench, and then through established operation commands, the computer and the numerical control device control the servo system to operate. At this time, the servo system can drive the workbench to translate and turn, so as to complete the position and angle of the workpiece on the workbench and cooperate with the drill bit to perform fine machining operations on the workpiece. When the traditional numerically controlled intelligent workbench is in use, it mostly uses a lead screw drive method to complete the movement operation of the workbench. However, during the machining of the workpiece, a certain amount of metal chips will be generated. Since the lead screw is often exposed in the working environment, the metal chips generated by the workpiece machining are likely to adhere to the lead screw, which is likely to cause a certain impact on the transmission work of the lead screw. For this reason, we propose a numerically controlled intelligent workbench with a positioning function and multi-angle rotation. Summary of the Invention

[0003] The purpose of the present invention is to provide a numerically controlled intelligent workbench with a positioning function and multi-angle rotation to solve the problems raised in the above background technique. The numerically controlled intelligent workbench with a positioning function and multi-angle rotation of the present invention includes a base. Two mounting frames are fixedly connected to the top of the base. A lead screw is rotatably connected between the two mounting frames. A transmission seat is threadedly connected to the lead screw. A mounting seat is fixedly connected to the top of the transmission seat. A load-bearing frame is rotatably connected to the top of the mounting seat. A table body is rotatably connected to the load-bearing frame. A cover cylinder is fixedly connected between the two mounting frames. The cover cylinder is sleeved outside the lead screw. A limiting port A is opened at the bottom of the cover cylinder. Fixed frames are fixedly connected to both sides of the transmission seat. Shoveling plates are fixedly connected to the bottoms of the fixed frames. The bottoms of the shoveling plates are attached to the inner bottom wall of the base.

[0004] Preferably, sliding rails are fixedly connected to both sides of the base. The two sides of the bottom of the mounting seat are respectively slidably connected to the sliding rails on the same side of it. Dust collection ports are opened on one side of the base close to the mounting frames. The two dust collection ports are located between the two mounting frames.

[0005] Preferably, a limiting port B is opened on the transmission seat. The transmission seat is sleeved on the cover cylinder through the limiting port B and is slidably connected to the cover cylinder. The inner bottom wall of the transmission seat is slidably connected to the lead screw through the limiting port A. Guide arc surfaces are provided on both sides of the shoveling plate.

[0006] Preferably, a fixed motor is fixedly connected to one side of the load-bearing frame. The output end of the fixed motor is fixedly butted with the end of the rotating shaft of the table body on the same side of it.

[0007] Preferably, linear guide rails are fixedly connected to both sides of the top of the frustum. A limiting plate is slidably connected between the two linear guide rails, and the bottom of the limiting plate is slidably connected to the top of the frustum.

[0008] Preferably, a driving motor is fixedly connected to the mounting bracket on one side of the base, and the output end of the driving motor is fixedly connected to the end of the lead screw on the same side.

[0009] During the workpiece processing of the present invention, the lead screw can be shielded by the cover cylinder. When debris generated during the workpiece processing falls on the cover cylinder, through the arc structure at the top of the cover cylinder, the debris can slide into the base. Then, as the rotating lead screw drives the transmission seat to move, the shovel plate can collect and push the debris located on the inner bottom wall of the base and push it into the dust collection port, avoiding the problem that in the traditional device, the transmission effect is easily reduced due to metal debris adhering to the lead screw during processing. It effectively improves the protection of the lead screw by the device and the effect of collecting and cleaning the debris. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0012] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0013] As Figures 1-5, a multi-angle rotating CNC intelligent workbench with a positioning function, comprises a base 1, both sides of the base 1 are fixedly connected with slide rails 11, the top of the base 1 is fixedly connected with two mounting frames 2, a dust collecting port 12 is opened on one side of the base 1 close to the mounting frame 2, the two dust collecting ports 12 are located between the two mounting frames 2, a screw rod 21 is rotatably connected between the two mounting frames 2, a driving motor 22 is fixedly connected to the mounting frame 2 on one side of the base 1, the output end of the driving motor 22 is fixedly connected to the end of the screw rod 21 on the same side, the bottom sides of the mounting seat 4 are respectively slidably connected to the slide rails 11 on the same side, the screw rod 21 is threadedly connected with a transmission seat 3, the top of the transmission seat 3 is fixedly connected with the mounting seat 4, the bottom sides of the mounting seat 4 are respectively slidably connected to the slide rails 11 on the same side, the top of the mounting seat 4 is rotatably connected with a load-bearing frame 41, the load-bearing frame 41 is rotatably connected with a table body 42, one side of the load-bearing frame 41 is fixedly connected with a fixed motor 43, and the output end of the fixed motor 43 is fixedly docked with the end of the rotating shaft of the table body 42 on the same side.

[0014] Furthermore, the base 1 is the main load-bearing structure. The slide rail 11 can make the mounting seat 4 more stable during movement. The dust collecting ports 12 on both sides of the base 1 can be used to collect metal debris. When the parallel position of the platform 42 needs to be moved, the driving motor 22 is started to drive the screw rod 21 to rotate. When the screw rod 21 rotates, it cooperates with the limiting effect of the slide rail 11 to drive the mounting seat 4 to perform translational work. When the inclination of the platform 42 needs to be changed, the fixed motor 43 is started to directly drive the platform 42 to rotate, so that the angle of the platform 42 can be adjusted.

[0015] Combined with Figure 1 , Figure 3 , Figure 4 and Figure 5 As shown, a cover cylinder 23 is fixedly connected between the two mounting frames 2, and the cover cylinder 23 is sleeved outside the screw rod 21. A limiting opening A24 is provided at the bottom of the cover cylinder 23. Fixed frames 32 are fixedly connected to both sides of the transmission seat 3. A shovel plate 33 is fixedly connected to the bottom of the fixed frame 32. The bottom of the shovel plate 33 fits with the inner bottom wall of the base 1. A limiting opening B31 is provided on the transmission seat 3. The transmission seat 3 is sleeved on the cover cylinder 23 through the limiting opening B31 and is slidably connected to the cover cylinder 23. The inner bottom wall of the transmission seat 3 is slidably connected to the screw rod 21 through the limiting opening A24, and guide arc surfaces 34 are provided on both sides of the shovel plate 33. During the workpiece processing, the screw rod 21 can be shielded by the cover tube 23. When the debris generated during the workpiece processing falls on the cover tube 23, the arc structure on the top of the cover tube 23 can make the debris slide into the base 1. Then, as the rotating screw rod 21 drives the transmission seat 3 to move, the shovel plate 33 can collect and push the debris on the bottom wall of the base 1 and push it into the dust collecting port 12 to complete the debris collection work.

[0016] Combined with the attached Figure 1 As shown, both sides of the top of the frustum 42 are fixedly connected with linear guide rails 5. A limiting plate 51 is slidably connected between the two linear guide rails 5, and the bottom of the limiting plate 51 is slidably connected with the top of the frustum 42. After placing the workpiece on the frustum 42, the linear guide rails 5 are used to drive the limiting plate 51 to approach the workpiece. When the limiting plate 51 fits against one side of the workpiece, the thrust generated as the limiting plate 51 moves can straighten the workpiece and limit one side of the workpiece, so that when the inclination of the frustum 42 is adjusted, the workpiece will not slide off the frustum 42, improving the stability during workpiece processing.

[0017] Working principle: First, install the device at the specified working position. After placing the workpiece on the frustum 42, the linear guide rails 5 are used to drive the limiting plate 51 to approach the workpiece. When the limiting plate 51 fits against one side of the workpiece, the thrust generated as the limiting plate 51 moves can straighten the workpiece and limit one side of the workpiece; when it is necessary to move the parallel position of the frustum 42, start the drive motor 22 to drive the lead screw 21 to rotate. When the lead screw 21 rotates, with the limiting effect of the slide rail 11, the mounting seat 4 can be driven to perform a translation operation. When it is necessary to change the inclination of the frustum 42, start the fixed motor 43 to directly drive the frustum 42 to rotate, and the angle of the frustum 42 can be adjusted. After the adjustment is completed, the workpiece can be processed using an externally connected drill bit; during the workpiece processing, the lead screw 21 can be shielded by the cover cylinder 23. When debris generated during the workpiece processing falls on the cover cylinder 23, through the arc structure at the top of the cover cylinder 23, the debris can slide into the base 1. Then, as the rotating lead screw 21 drives the transmission seat 3 to move, the scraping plate 33 can collect and push the debris located on the inner bottom wall of the base 1 and push it into the dust collection port 12 to complete the collection of the debris.
