Abstract
The invention relates to a centering clamping mechanism of a CNC (Computerized Numerical Control) drilling machine for pipe fittings, arranged on a drilling platform of the CNC drilling machine. The centering clamping mechanism of the CNC drilling machines for pipe fittings comprises two clamping blocks which are arranged at both sides of the circumference of a pipe fitting and can move along the horizontal diameter direction of the pipe fitting, nuts are arranged at the lower parts of the two clamping blocks and engaged with a positive and negative screw mandrel which has two sections of opposite threads and is supported by the middle of a supporting seat, the supporting seat is fixedly connected with the drilling platform, and a rotating motion driving mechanism is arranged at one end of the positive negative screw mandrel. According to the invention, the positive negative screw mandrel is driven to rotate by adopting a hydraulic motor, the clamping blocks at both sides are driven to simultaneously homodromously or oppositely move and rapidly finish the centering and clamping action to the symmetrical outer walls of a cylinder, a hydraulic motor controls and drives the centering and clamping action through a hydraulic station, the action and the speed can be accurately controlled through a CNC console and the automation requirement with high efficiency is accurately satisfied, and the pipe fitting can be slowly and effectively clamped hydraulically to prevent mechanical clamping from causing impact and damage to the pipe fitting.
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, clamp assemblies comprises first grip block and second grip block that is arranged on the pipe fitting both sides, can make clamp along the relative motion of pipe fitting horizontal diameter direction by the manual screw mandrel feed wheel that shakes both sides respectively, hold tightly or loosen pipe fitting; The drill unit assembly comprises drill bit, by drilling main shaft and motor and transmission mechanism drives and feeding, adopts for example unit head assembly of general NC drilling machine or CNC milling machine of prior art, after clamp assemblies is fixing pipe fitting is carried out outer wall boring and processes.At present the method time of manual adjustment grip block long, efficient is low, poor stability can not satisfy the needs of automated production.
Summary of the invention
The applicant adopts the manual adjustment grip block time long at above-mentioned existing pipe fitting numerical control drilling machine, efficient is low, shortcomings such as poor stability provide a kind of centering clamp mechanism of the pipe fitting numerical control drilling machine by hydraulic control, can fast and safely clamp the pipe fitting outer wall.
The technical solution adopted in the present invention is as follows:
A kind of centering clamp mechanism of pipe fitting numerical control drilling machine, be arranged on the drilling platform of described numerical control drilling machine, comprise two clamps that can move along pipe fitting horizontal diameter direction that are positioned at pipe fitting circumference both sides, described two clamp bottoms are provided with screw, be meshed with the forward lead screw of two sections that support by the supporting seat middle part anti-phase silk teeth, described supporting seat is fixedlyed connected with described drilling platform; The described forward lead screw one end setting driving mechanism that rotatablely moves.It is further characterized in that:
The described driving mechanism that rotatablely moves adopts hydraulic motor, controls driving by Hydraulic Station.
The present invention adopts the rotation of fluid motor-driven forward lead screw, drives the relative simultaneously or reverse motions of clamp of both sides, finishes the centering clamping action for the circular tube external wall of symmetry fast; Hydraulic motor is controlled and is driven by Hydraulic Station, by numerical control console accurately control action and speed, efficiently and accurately satisfy the automation requirement; Hydraulic clamp can slowly effectively clamp pipe fitting, prevents impact and damage that mechanical grip causes pipe fitting.
Description of drawings
Fig. 1 is a front view of the present invention.
The specific embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described.
As shown in Figure 1, first grip block 402 of drilling platform and second grip block, 403 bottoms are provided with screw 404, are meshed with screw mandrel 405.Screw mandrel 405 middle parts are supported by taper roll bearing 407 by screw mandrel supporting seat 406, and supporting seat 406 is fixed on the mobile drilling platform 4, are positive and negative silk teeth at screw mandrel supporting seat 406 both sides screw mandrels 405; Screw mandrel 405 drives by the hydraulic motor 401 of end, and hydraulic motor 401 is controlled and driven by Hydraulic Station, is prior art; When screw mandrel 405 rotations; the screw 404 that drives both sides makes first grip block 402 draw close or open outside the phase reversing tube simultaneously to pipe central authorities along pipe fitting horizontal diameter direction is simultaneously relative with second grip block 403, thereby can adapt to the pipe fitting that clamps different tube diameters by fast and flexible.
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, for example hydraulic motor is changed into servomotor.
