Abstract
The utility model discloses a lead screw brake shoe feed automatic threading machine for steel tubes, which belongs to thread processing equipment and particularly relates to a threading machine using a lead screw brake shoe to drive a threading machine head to feed. The lead screw brake shoe feed automatic threading machine for steel tubes comprises a main spindle box assembly capable of moving on a lathe bed horizontal sliding rail and provided with a power device, and a die holder and a die movable ring are mounted at the front end of a main spindle box. The lead screw brake shoe feed automatic threading machine for steel tubes is characterized in that a lead screw assembly formed by a lead screw shaft, a bearing and a support is fixed on the outer side of the main spindle box, a driving chain wheel is mounted at the tail end of a spindle and connected with a driven chain wheel mounted at the tail end of the lead screw shaft through a chain, a brake shoe and a brake shoe control device for controlling the brake shoe to be separated from the lead screw shaft in a meshed mode are mounted below the lead screw shaft, and the brake shoe control device is mounted on the lathe bed. Due to the fact that a lead screw brake shoe mechanism is adopted to push the main spindle box to feed, the feed speed is led to coordinate with the rotation speed of the spindle, the problem of discordance of the feed speed and the rotation speed of the spindle caused by the fact that hydraulic push feed is affected by pressure and temperature of hydraulic oil is avoided, and product quality is improved.
Description
Technical field
The utility model belongs to thread processing equipment, particularly uses the leading screw brake shoe to drive the die head threading machine that the mantle fiber head advances.
Background technology
Some short steel pipes two ends of playing the connection effect all need process the screw thread that connects usefulness; And require the two ends screw thread to have concentricity preferably, the method for processing the two ends screw thread usually is that two ends process respectively, promptly process an end after; With the steel pipe clamping again reprocessing other end that overturns; This method working (machining) efficiency is low, labour intensity is big, and the axis angle of two head threads is not easy substandard requirement, and the quality product rate is low.Applicant's the ZL of patent formerly 201020193817.2 discloses the automatic die head threading machine of a kind of steel pipe double end; It is characterized in that: feed mechanism and raw material clamping device are housed on the center line on T shape chassis and the bracing frame; The center line bilateral symmetry is equipped with the main spindle box that the mantle fiber screw die is installed, and is fixing the line slideway slide block that can on line slideway, slide on the main spindle box backing plate of main spindle box bottom, is fixed on the main spindle box oil cylinder of advancing is housed on the oil cylinder installing rack on the bracing frame; Owing to adopted automatic charging and once clamped two ends machining screw simultaneously; Realized process automation, promptly guaranteed product two ends screw threads axis angle reach standard-required, can raise the efficiency again; Realize a people's two-shipper or a multimachine, reduce working strength of workers.But because this equipment is when the machining screw feeding, by hydraulic feed: the cutter F.F. becomes the worker near workpiece and advances (slow-motion) machining screw.Must adjust the hydraulic pressure deceleration valve when speed of mainshaft changes, and slight the variation take place in the Hydraulic Elements precision of hydraulic system, hydraulic fluid temperature etc., all can influence the thread quality of processing.
The utility model content
Use the stable inadequately deficiency of hydraulic cylinder feed in order to overcome existing die head threading machine; The utility model provides a kind of leading screw brake shoe feeding steel pipe automatic die head threading machine; The automatic die head threading machine of this leading screw brake shoe feeding steel pipe uses leading screw brake shoe feed mechanism; Substitute the hydraulic feed mode, realized that main axis rotation and axial feed keep synchronously, further improve the automatic die head threading machine machining screw of steel pipe quality, reduce waste product.
The utility model solves the technical scheme that its technical problem adopted: the automatic die head threading machine of a kind of leading screw brake shoe feeding steel pipe; Comprise the main spindle box assembly that has power set that can on the lathe bed horizontal slide rail, move; The main spindle box front end is equipped with die-head and screw die folding ring; It is characterized in that: the leading screw assembly of being made up of lead screw shaft, bearing, support is being fixed in the main spindle box outside; The main shaft tail end is equipped with drive sprocket and is connected with the driven sprocket that is installed in the lead screw shaft tail end through chain, and the brake shoe control device of brake shoe and control brake shoe and lead screw shaft engagement disengaging is equipped with in the lead screw shaft below, and the brake shoe control device is installed on the lathe bed.
Described brake shoe control device comprises the fixing brake shoe axis of guide in bed, and the tail end of the horizontal segment of L type brake shoe seat is equipped with the fairlead that can slide up and down along the axis of guide, and the brake shoe cylinder that is fixed on the lathe bed is equipped with in the below of L type brake shoe seat horizontal segment.
The control appliance of described brake shoe cylinder is a magnetic valve.
The gear ratio of described drive sprocket and driven sprocket is 1: 2.
The operation principle of the utility model: utilize main axis rotation to drive the leading screw rotation; Main axis rotation 1 is changeed, and leading screw rotation 1/2 is changeed, and hydraulic pressure is assisted when promoting cutter fast near workpiece; Hydraulic pressure stops; Brake shoe and lead screw shaft engagement under the promotion of brake shoe cylinder is carried out machining screw by leading screw, brake shoe cooperation, guarantees that the tool feeding amount is consistent with the thread pitch of processing.
The utility model increases leading screw, shoe plate assembly on original die head threading machine, and is controlled automatically by PLC, must manually-operated.
Improve back processing action order: the feeding of main spindle box drives by the fast feed of hydraulic oil cylinder driving main spindle box; When the F.F. release; Magnetic valve is opened the air cylinder driven brake shoe and is risen; Make the engagement of brake shoe and lead screw shaft, the main spindle box feeding changes the worker into advances, and begins to get into the mantle fiber duty after idle running 2～3 button pitch; Mantle fiber is accomplished, and when the folding ring was opened die-head, the brake shoe cylinder fell; Brake shoe and lead screw shaft are broken away from; Be installed under the extension spring effect between the lathe bed of main spindle box and main spindle box rear end, die-head and workpiece hightail, and the jig slide plate is retreated; The switching-over of main spindle box oil cylinder, the driving main shaft case is retreated to original position.
The beneficial effect of the utility model is owing to adopt the feeding of leading screw brake shoe mechanism urges main spindle box; Make feed speed consistent, avoided original hydraulic drive feeding to receive hydraulic fluid pressure temperature effect to cause feeding rate and the inharmonic problem of the speed of mainshaft, reduced the adjustment difficulty of equipment with the main axis rotation speed coordination; Need not to worry that oil pressure changes to cause to the pipe fitting screw thread reins in a phenomenon; And a waste product of reining in that does not match and cause because of the speed of mainshaft and pitch, and hydraulic pressure changes to what the pipe fitting screw thread caused and reins in a phenomenon, stablizes and improves the quality of products; Per tour reduces adjustment test-run a machine spare 2-3 spare, and qualification rate improves 0.5-1%.
