Abstract
The invention relates to a rotary main shaft structure of a pipe fitting numeric control drilling machine. A motor is arranged in a main shaft box and connected with a main shaft through a transmission part and a speed reducer; two ends of the main shaft are arranged on a box wall of the main shaft box; a chuck is arranged at the front end of the main shaft; and the transmission part is a synchronous belt transmission series, which comprises a small synchronous belt wheel, a synchronous belt and a large synchronous belt wheel; and the large synchronous belt wheel is arranged in the middle of the main shaft. By adopting a servo motor, the rotation speed can be freely regulated and the positioning precision is improved. The rotary main shaft structure of the pipe fitting numeric control drilling machine is driven by the synchronous belt, the synchronous belt can completely meet the requirements for rotating and accurately positioning a pipe fitting because the pipe fitting rotates without larger rotation force, and the invention has the advantages of stable and reliable transmission, better flexibility and lower cost.
Description
Technical field
The present invention relates to field of machine tool equipment, in particular for the numerical control drilling machine of processing pipe part areole.
Background technology
Pipe parts such as boiler header need be processed a lot of through holes or blind hole on the tube wall of pipe, the pipe fitting numerical control drilling machine of the applicant's research and development is clamped in the two ends of pipe fitting on the workbench by rotating chuck, the drilling platform movably is arranged on the workbench, the drilling platform is provided with the clamp assemblies and the drill unit assembly of processing pipe fitting, after clamp assemblies is fixing pipe fitting is carried out outer wall boring processing.Present rotary main shaft structure utilizes gears engaged to carry out transmission, and rotating chuck adopts mechanical chuck, and rigidity is stronger, and cost is higher, easily the pipe fitting that is held is caused damage.
Summary of the invention
The applicant adopts rigidity clamping and transmission easily to cause shortcomings such as pipe fitting damage at above-mentioned existing pipe fitting numerical control drilling machine, and a kind of rotary main shaft structure of pipe fitting numerical control drilling machine is provided, and clamping pipe fitting that can be steadily flexible is also realized stable rotation.
The technical solution adopted in the present invention is as follows:
A kind of rotary main shaft structure of pipe fitting numerical control drilling machine, motor is set in main spindle box, be connected with main shaft with drive disk assembly by reductor, the main shaft two ends are erected on the tank wall of main spindle box, front-end of spindle is equipped with chuck, described drive disk assembly is to be with power train synchronously, comprises small synchronous pulley, synchronous band, big synchronous pulley, and described big synchronous pulley is arranged on the main shaft middle part.It is further characterized in that:
Described chuck is an oild chuck;
Described motor is a servomotor.
The present invention adopts servomotor, can freely adjust the revolution rotating speed, improves positioning accuracy; The present invention adopts synchronous band transmission, because the pipe fitting rotation does not need bigger turning power, therefore band can satisfy rotary tube piece and pinpoint requirement fully synchronously, and stable drive is reliable, and better flexible, cost is lower; The present invention adopts oild chuck replacement mechanical chuck that pipe fitting end is carried out clamping, because hydraulic pressure is steadily reliable, speed is slowly even, therefore can avoid rigid mechanical clamping impulsive force big, the drawback of fragile pipe fitting end.
Description of drawings
Fig. 1 is a front view of the present invention, broken section;
Fig. 2 is a vertical view of the present invention, broken section.
The specific embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described.
As shown in Figure 1 and Figure 2, on main spindle box 9 internal backplane servomotor 8 is installed, its output by reductor 7, small synchronous pulley 6, be with 4 synchronously, big synchronous pulley 5 is connected with main shaft 2, big synchronous pulley 5 is arranged on the middle part of main shaft 2, can adopt keyway to cooperate, also can adopt the mode of axis hole interference fit to connect.Main shaft 2 is installed in by the two terminal circle taper roller bearing on the tank wall of main spindle box 9, and preceding end bearing installation place main shaft protecgulum 3 cooperates with felt collar installs and uses dust seal; Locking nut is installed to eliminate end play in tail end bearing installation place, main shaft bonnet 10 and felt collar is installed again, dust seal.At main shaft 2 oild chuck 1 is installed foremost.Oild chuck 1 and hydraulic control technology are prior art, are common in the oild chuck that the numerically controlled lathe clamping part uses; Servomotor 8 also adopts the commercial goods; Electric and the hydraulic control of concentrating by the numerical control platform of numerical control drilling machine.
During real work, earlier carry out clamping by the end of 1 pair of processed pipe fitting of oild chuck, driving reductor 7 by servomotor 8 rotates, the synchronous pulley 6 of reductor 7 axle heads rotates together by being with the big synchronous pulley 5 of 4 drives synchronously, rotate thereby drive main shaft 2, the oild chuck 1 on the main shaft 2 is done gyration with main shaft 2.
More than describing is explanation of the invention, is not that institute of the present invention restricted portion is referring to claim to the qualification of invention, and under the situation of spirit of the present invention, the present invention can do any type of modification.
Claims (3)
1. the rotary main shaft structure of a pipe fitting numerical control drilling machine, motor is set in main spindle box, be connected with main shaft with drive disk assembly by reductor, the main shaft two ends are erected on the tank wall of main spindle box, front-end of spindle is equipped with chuck, it is characterized in that: described drive disk assembly comprises small synchronous pulley, synchronous band, big synchronous pulley for being with power train synchronously, and described big synchronous pulley is arranged on the main shaft middle part.
