Description
Technical field
The present invention relates to the machining equipment field, especially the clamping device of pipe cutter.
Background technology
Pipe cutter is the equipment of cutting or processing metal pipe material or bar, and the pipeline section after the cutting can be made parts such as bearing ring, has characteristics such as high efficiency, specificity.In the at present common pipe cutter processing; Be cut the pipe material and send into the folder hole of chuck usually from the outside; Chuck grasps pipe material outer rim front end and cuts, the clamping contact portion of this clamp structure seldom, grip is relatively poor; Influence cut quality, especially be difficult to processing for the less lasso of width; And after once cutting is accomplished, need stop the rotation of main shaft, thus artificially to carry out feeding from the outside and cut next time, this processing mode efficient is low, and labour intensity is big.In some pipe cutters, also adopt the structure of inner feeding, retained part is more like this, can obtain grip preferably, but measured length feed mechanism more complicated, and the feeding effect is relatively poor, influences the reliability and the automation control of equipment.
Summary of the invention
The applicant is to above-mentioned existing pipe cutter clamp structure and feed mechanism complex structure; Influence shortcomings such as crudy and equipment dependability; A kind of clamping device of pipe cutter rational in infrastructure is provided, thereby can realizes managing the feeding of material continuously and automatically, improve efficiency of equipment.
The technical scheme that the present invention adopted is following:
A kind of clamping device of pipe cutter is arranged on the hollow spindle front end of pipe cutter, and collet rear is fixed on the main shaft endoporus through the main shaft fixed head; Chuck head rear end is the conical surface, and with the cone match of pushing clamping sleeve front end, the rear end of pushing clamping sleeve is connected with the chuck pushing pipe, and chuck pushing pipe rear end connects the cylinder piston of pipe cutter afterbody; In the mesopore of the rear portion of chuck, be provided with the feeding chuck, feeding chuck rear end connects feeding chuck pushing pipe, and feeding chuck pushing pipe rear end is connected with the feeding cylinder piston.It is further characterized in that:
Be arranged with tubule in the said feeding chuck internal diameter and directly expect cover, tubule is directly expected to overlap front outer and is had certain tapering.
Said feeding chuck is a circle ring column, and the front portion is divided into some fan-shaped blocks by slot segmentation, and the open front diameter is less than rear portion inner ring surface diameter.
Said feeding chuck material is a spring steel.
The present invention adopts inner feeding style, can be large-area in process to the effective clamping of processed pipe material, improved the stability of processing, and tailing is short, saves material; And can realize synchronous feeding, automaticity is high, and working (machining) efficiency improves greatly.The present invention adopts independently feed mechanism of inside, adopts feeding cylinder to control, and can realize accurately sending to, guarantees dimensional uniformity; The feeding chuck adopts spring steel to carry out predeformation through Overheating Treatment, has elasticity preferably, and while grip simple for structure is excellent.The present invention directly expects parts such as cover through the tubule of changing different inner diameters, can adapt to the pipe material and the bar of various outer diameter, plurality of specifications flexibly, has improved the adaptability of equipment.
Description of drawings
Fig. 1 is a cutaway view of the present invention;
Fig. 2 is the stereogram of Fig. 1;
Fig. 3 is the stereogram of feeding chuck part of the present invention.
The specific embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described.
Like Fig. 1, shown in Figure 2; The clamping device of pipe cutter of the present invention is arranged on hollow spindle 1 front end of pipe cutter; Chuck 7 rear portions are through the main shaft fixed head 3 that is threaded; Main shaft fixed head 3 is fixed on main shaft 1 endoporus, the end through main shaft before and cap 6 push against sleeve 12 and position, chuck 7 and the fixing no relative displacement of main shaft.Chuck 7 head rear ends are the conical surface 11; Cone match with pushing clamping sleeve 5 front ends; The rear end of pushing clamping sleeve 5 and chuck pushing pipe 9 are through being threaded, and chuck pushing pipe 9 rear ends connect the cylinder of pipe cutter afterbody, under the moving of cylinder piston, move forward and backward; Promote or pulling pushing clamping sleeve 5, anterior chuck 7 is clamped perhaps loosen.In the mesopore of the rear portion of chuck 7, be provided with feeding chuck 4, the feeding chuck 4 rear end outer rims feeding chuck pushing pipe 10 that is threaded, the rear end of feeding chuck pushing pipe 10 is connected with feeding cylinder; The pipe that is cut for diameter is thinner expects or bar that can be arranged with tubule in feeding chuck 4 internal diameters and directly expect to overlap 2, tubule is directly expected to overlap 2 front outers and had certain tapering.
As shown in Figure 3, feeding chuck 4 adopts the spring steel material to make, and is shaped as circle ring column, and front end is provided with slot segmentation; Go out slot segmentation in its nose cut during actual processing and manufacturing, make it be divided into some fan-shaped blocks, adopt modes such as wire binding or clamp then; Make fan-shaped block warpage cross distortion; After crossing the feeding chuck 4 employing heat treatments coolings after being out of shape, loosen steel wire or anchor clamps again, secter pat is known from experience at this moment has the part resilience, but organizes variation after the heat treatment; Make it have certain predeformation amount that tightens up, open front 401 diameters are less than the diameter of rear portion inner ring surface 402.
Real work can be decomposed into following steps: (one) is cut or processed pipe material or bar sent to from the inside of main shaft 1; As shown in Figure 1 promptly is to send into from the left side; This moment, chuck pushing pipe 9 was retreated with pushing clamping sleeve 5; Chuck 7 is in relaxation state, and pipe material front end extend out to from the folder hole 8 at the middle part of chuck 7 needs Cutting Length.(2) cylinder piston of pipe cutter afterbody driving chuck pushing pipe 9 advances with pushing clamping sleeve 5, under the effect of the pushing clamping sleeve 5 front end conical surfaces, and chuck 7 pinch tube material, cutting tool is processed the pipe material.(3) cutting is accomplished back chuck pushing pipe 9 this moment and pushing clamping sleeve 5 and is retreated and reset, and chuck 7 loosens; Under the driving of feeding cylinder; Feeding chuck pushing pipe 10 is sent certain distance forward to feeding chuck 4; Owing to after feeding chuck 4 predeformation pipe material is had certain clamping force; Therefore can hold tightly to manage to expect to manage and expect to send distance to a declared goal to, when sending to, will accomplish the pipeline section release of cutting and accomplish discharging.(4) cylinder piston of pipe cutter afterbody is sent to once more; Driving chuck pushing pipe 9 advances with pushing clamping sleeve 5; Chuck 7 pinch tube material, this moment, the feeding cylinder rollback resetted, and feeding chuck pushing pipe 10 moves backward with feeding chuck 4 and resets; Because anterior chuck 7 pinch tube material, so feeding chuck 4 is by rollback by force; Cutting tool is processed the pipe material then.The present invention need not stop the rotation of main shaft in the process of feeding, can realize synchronous feeding, and automaticity is high, and working (machining) efficiency improves greatly.
The present invention through the tubule of changing different inner diameters directly expect to overlap 2 with feeding chuck 4 parts such as grade, can adapt to the pipe material and the bar of various outer diameter, plurality of specifications flexibly, improved the adaptability of equipment.
More than describing is to explanation of the present 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.
