Description

Knee end face and fusion treating device

The utility model relates to a kind of device of processing elbow end face and groove, is applicable to the elbow bend of the various calibers of processing.

The device of existing processing elbow.Boring machine processing: the elbow two ends will just can be finished through twice clamping and twice processing, are that the process-cycle is long outside its deficiency, lathe work time cost height.Machined into: add bent plate and process on cutterhead, the elbow two ends will just can be finished through twice clamping and twice processing equally, and its weak point is that the process-cycle is longer, and the lathe work time cost is higher.A kind of pipeline square groove turning machine was disclosed on March 22nd, 1989, application number is 89210164.1, its objective is the end face and the groove of processing straight pipeline, form by cutterhead tumbler, cutterhead mobile device and anchor clamps, each one of plane lathe tool and groove lathe tool is housed on the cutterhead, and its weak point is to process elbow; Feeding is to finish by the hand control handle, thereby labour intensity is bigger, and efficient is lower.

The purpose of this utility model is to avoid above-mentioned weak point of the prior art and a kind of device that can process elbow and carry out machining automatically is provided.

The purpose of this utility model can reach by following measure: be made up of two groups of unit heads, two groups of float cutter, two groups of feeding cylinders and one group of Workpiece clamping device, be installed on the shared support.Unit head is a standarized component, form by motor, speed change gear and main shaft, the cutter that floats is made up of the cutter hub of band dovetail groove and the knife bar of band dovetails, flat knife, groove cutter and alignment device are housed on the knife bar, alignment device is made up of roller, spring and bolt, and Workpiece clamping device is made up of clamping cylinder, geometrical clamp and mobile folder.Knife bar slides in the dovetail groove of cutter hub together with flat knife, groove cutter and roller, in order to centering before just adding.Preparation before the processing comprises clamping, tool setting, centering and adjustment.Workpiece to be processed (elbow) is placed between geometrical clamp and the mobile folder, start clamping cylinder elbow is clamped; Start the feeding cylinder, pushing away unit head and moving forward and backward, flat knife and groove cutter are moved to correct position, to finish the tool setting operation along the direction of axis line of unit head; Start another group feeding cylinder then, finish the tool setting operation of another group flat knife and groove cutter; The bolt of tightening alignment device makes the roller that stretches in the elbow mouth of pipe under the elastic force effect to add the elastic force of big spring, is close to the medial surface of bend pipe, and the groove size that processes with assurance is equal distribution on circumference, thereby finishes the centering operation; In like manner, adjust another group alignment device, to finish the centering operation of another group; Adjust the position of two groups of travel switches.Begin processing: start two groups of unit heads, it is moving that the main shaft band unsteady swivel; Start two groups of feeding cylinders, flat knife and groove cutter are processed simultaneously to two end faces of elbow, treat that the feeding cylinder bumps to travel switch, feeding cylinder feed-disabling is also return fast, unit head stops together with flat knife and groove cutter simultaneously, like this, satisfied the requirement that the working angles of elbow end face and groove carries out automatically; Start clamping cylinder, mobile folder is return the elbow that processes to unclamp elbow, to unload, and all process finishes.If the elbow of continuation processing same specification, with regard to the button-up operations before must not processing again, if process the elbow of another kind of caliber specification, in case of necessity, the geometrical clamp of changing Workpiece clamping device gets final product with mobile folder and unsteady cutter.Owing to the geometrical clamp and the mobile folder of every group of float cutter and Workpiece clamping device, can adapt to the elbow of close caliber, so the unsteady cutter of different tube diameters elbow and the geometrical clamp of Workpiece clamping device can lack than the caliber specification number with the group number that moves folder.

The utility model contrast prior art has following advantage: come compared with boring machine and machined into, must clamping, twice of centering and processing, two end faces and the groove that can time processing become elbow, thereby, the efficient height, expense is low during the lathe platform, and cutting process has been realized automation, crudy is good, and labour intensity is low.Compared with application number is that 88210164.1 disclosed pipeline square groove turning machines come, and has overcome the deficiency that this machine can not be processed elbow, the efficient height, and cutting process has been realized automation, and crudy is good, and labour intensity is low.

The drawing explanation of accompanying drawing:

Fig. 1 is the utility model floor plan.

Fig. 2 is the systematic schematic diagram of hydraulic means, and electric control system shows in the drawings to be expressed.

The utility model is described in further detail below in conjunction with embodiment.See Fig. 2 by float cutter 2, two groups of feeding cylinder 3(of two groups of unit heads 1, two groups), one group of workpiece clamps and adorns 4 and form, be installed on the shared support 5.The cutter 2 that floats is made up of cutter hub 6 and knife bar 7, and flat knife 13, groove cutter 12 and alignment device are housed on the knife bar 7, and alignment device is made up of roller 8, spring 9, bolt 10 and rolling bearing 11; Workpiece clamping device 4 is made up of clamping cylinder 14, geometrical clamp 15 and mobile folder 16.Knife bar 7 slides in the dovetail groove of cutter hub 6 together with flat knife 13, groove cutter 12 and roller 8, in order to centering before the processing.Elbow to be processed 17 is placed between geometrical clamp 15 and the mobile folder 16, start clamping cylinder 14 elbow 17 is clamped; Start feeding cylinder 3, pushing away unit head 1 and moving, flat knife 13 and groove cutter 12 are moved to correct position, finish the tool setting operation along the unit head direction of axis line; Start another group feeding cylinder then, finish the tool setting operation of another group flat knife and groove cutter; Tighten the bolt 10 of alignment device, make the roller 8 that stretches in elbow 17 mouths of pipe under the effect of spring force, be close to the medial surface of bend pipe, the groove size that processes with assurance is equal distribution on circumference, thereby finishes the centering operation; Simultaneously, adjust another group alignment device, to finish the centering operation of another group; Adjust two groups of travel switch 18(and see Fig. 2) the position.Begin processing: start two groups of unit heads 1, the main shaft band unsteady cutter 2 and is rotated; Start two groups of feeding cylinders 3,17 two end faces of 12 pairs of elbows of flat knife 13 and groove cutter are processed simultaneously, treat that feeding cylinder 3 bumps to travel switch 18, feeding cylinder 3 feed-disablings are also return fast, unit head 1 stops together with flat knife 13 and groove cutter 12 simultaneously, like this, realized the automation of elbow 17 end faces and groove working angles; Start clamping cylinder 14, move folder 16 and return the elbow that processes to unclamp elbow 17, to unload, all process finishes.Because feed, parking and withdrawing are to carry out automatically by the position of adjusting, so the elbow end face width dimensions and the groove dimensional accuracy that process are higher, can meet international standards, and can satisfy the requirement of outlet.
