The specific embodiment
Motor and cycloidal planetary gear speed reducer are selected the YLB1.5-59 type for use, and part material is that 700mm is long with #45 steel or 40 chromium, hollow screw mandrel, and two ends have spline, and middle is the T60X8 screw mandrel partly; Motor direct connection shaft diameter is 45mm, and length is 500mm; Driving gear pair: modulus is 2, and the number of teeth all is 150 teeth; Differential gear is paid pair: modulus 2, driving wheel are 149 teeth, and driven pulley is 151 teeth.Earlier make shell by the shape of Fig. 1 (9) the utility model shell with steel plate, motor and cycloidal planetary gear speed reducer are fixed on the shell end face, its direct connection axle is installed in the housing with rolling bearing, and travelling gear is connected with the direct connection axle with spline respectively with differential gear; Fork mechanism adopts the fork mechanism on the lathe, is connected with differential gear, and its handle passes the side of shell.Another gear of driving gear pair and differential gear pair is installed in the housing with rolling bearing equally, and endoporus is connected with hollow screw mandrel with screw with spline respectively.Hollow screw mandrel places and the corresponding position of direct connection axle, its end immovable support.The knife rest cover is the steel bushing that makes Hough shape half by two, and sleeve lining has sinusoidal wave groove, and it is held on the hollow screw mandrel with the Hough clevis, on the corresponding position of knife rest.Knife rest is a Cylinder that matches with the knife rest cover, and its end is cutter head fixedly, and other end both sides are fixed with pin, and endoporus has spline.Umbrella shape fastener structure such as umbrella structure, do not adorn umbrella cover, draw at ordinary times, during use, pack into the tapping of container, open umbrella, the umbrella muscle is terminal to be contacted with domatic inwall to be processed, and umbrella handle is pressed in the perforate of vessel shell with gland and hand wheel nut after passing knife rest, knife rest cover, hollow screw mandrel.
Illustrate: motor arrives transmission of power on the motor direct connection axle (2) by cycloidal planetary gear speed reducer (1), then by driving gear pair (3), drives hollow screw mandrel rotation.Because motor direct connection axle (2) also is with differential gear pair (4) in going up also, the transmission speed ratio of differential gear pair (4) is little than the transmission speed ratio of driving gear pair (3), and hollow like this screw mandrel can only be by designing requirement feed at a slow speed.When withdrawing, the motor counter-rotating.With the fork that is installed on the groove processing machine shell (9) differential gear on the motor direct connection axle (2) is broken away from, at this moment hollow screw mandrel (5) rotates in the screw that does not rotate (differential gear pair), reaches the purpose of rapid return.The front end of hollow screw mandrel (5) is equipped with knife rest (7) and is wrapped in Hough shape knife rest cover (6) on knife rest (7) outer rim.Because knife rest cover (6) is to be connected with the Hough cover with hollow screw mandrel, it does not only rotate with retreating with hollow screw mandrel (5) advanced in unison.The cover inwall is processed with the sinusoidal wave groove different according to the saddle face degree of depth, so knife rest (7) with hollow screw mandrel (5) when rotating synchronously, the pin of its knife rest afterbody drives knife rest (7) in knife rest cover (6) inboard wall groove reciprocating, finishes the groove of milling shape of a saddle perforate.
At different-diameter vessel shell and different opening diameters, as long as several custom-designed knife rest covers of conversion (6) just can be processed various difform saddle face grooves respectively.The groove processing machine has been finished container diameter from Φ 600-Φ 3000 at present, and opening diameter is from the processing of whole saddle face grooves of DN50-DN600.Perforate roughing on the shell of tank all is to finish with the method for gas cutting.After finishing perforate, draw the fastening umbrella in the quick fastener of custom-designed umbrella shape (8) in insertion perforated container place.Open umbrella, and umbrella handle is penetrated in the hollow screw mandrel (5) of groove processing machine, pass processing machine shell (9), beveling machine is fastened in the container casing perforate, the groove processing machine is fixed on container casing tapping to be processed firmly to reach fast with hand wheel nut, gland.Locate fast and quick centering.If shape of a saddle groove processing machine shell (9) is fixed on the rocking arm workbench of combined rack.The Front-end Design of the main shaft screw mandrel of hollow screw mandrel (5) is a Mohs 3# tapering.Shape of a saddle groove processing machine can be finished milling, drilling and the turning processing in each orientation like this.It will be a multipurpose combination machining tool.
