Abstract
The invention relates to a gate valve rod screw processing single purpose machine, which is characterized in that the machine mainly comprises a rack, a transmission mechanism, a main shaft case body fixedly connected with the rack, the main shaft provided with a blade plate, a spring clip and a pitch contour hollow shaft, wherein the main shaft provided with the blade plate supports the bearing of the main shaft case body, and the main shaft is connected with a motor via the belt transmission; the taper of the front end of the spring clip is matched with the taper of the front end mouth of the pitch contour hollow shaft, and the spring clip passes through the pitch contour hollow shaft the back end of which is connected with a locking nut. The invention has the advantages that the machine meets the processing requirement of small-size civil gate valve rod screw, the semi-automatic production is realized, and the production efficiency is very high. The operation workers only put the valve rod into the spring clip to tightly clamp the valve rod, and then the acme thread of the valve rod can be molded at one time.
Description
Technical field
The invention belongs to valve and produce special equipment, relate in particular to a kind of gate valve rod screw processing single purpose machine.
Background technology
The trapezoidal thread processing of gate valve rod generally is to adopt lathe turning.Production efficiency is low.Valve rod for big specification adopts the whirlwind milling machine to carry out the milling moulding, though improved production efficiency, processing cost is also along with improve.Especially for the civilian gate valve of small dimension, the huge market demand must satisfy the production efficiency height, becomes to produce the low requirement of cost, could adapt to the competition situation in market.
Summary of the invention
The objective of the invention is to overcome the deficiency of above-mentioned technology, and a kind of gate valve rod screw processing single purpose machine is provided, realize semi-automatic production, production efficiency is very high, especially adapts to the processing request of the civilian gate valve rod screw thread of small dimension.
The present invention for achieving the above object, by the following technical solutions: a kind of gate valve rod screw processing single purpose machine, it is characterized in that: mainly by frame, transmission mechanism, the main shaft casing affixed with frame, the main shaft of cutterhead is installed, spring chuck and pitch pattern hollow shaft constitute, the described main shaft supporting of cutterhead that is equipped with is on the bearing of main shaft casing, main shaft is connected with motor by belt transmission is secondary, the tapering coupling of the tapering of described spring chuck front end and pitch pattern hollow shaft front port, spring chuck passes pitch pattern hollow shaft, and its rear end is bolted with locking nut.
Described pitch pattern hollow shaft cylindrical is provided with the screw thread with valve rod pitch coupling, described screw thread and the pattern screw engagement that is fixed on the frame, described pitch pattern hollow shaft two ends are slidingly connected with the carriage center axle sleeve that is fixed on the frame upper slide rest, and described pitch pattern hollow shaft tail end is linked with the feeding handle.
Fixedly 2-4 is cutter simultaneously for described cutterhead, and the cutter constant depth is on the position of same center circle.
Beneficial effect of the present invention: the processing request that especially adapts to the civilian gate valve rod screw thread of small dimension.Realize semi-automatic production, production efficiency is very high.The operator only needs valve rod is packed in the spring chuck, clamps valve rod, trapezoidal thread that can the one-shot forming valve rod.
Description of drawings

The specific embodiment
Describe the specific embodiment of the present invention in detail below in conjunction with accompanying drawing and preferred embodiment.
See accompanying drawing for details, a kind of gate valve rod screw processing single purpose machine, mainly by frame 1, transmission mechanism 2, constitute with affixed main shaft casing 3, the main shaft 5 that cutterhead 4 is installed, spring chuck 6 and the pitch pattern hollow shaft 7 of frame, the described main shaft supporting of cutterhead that is equipped with is on the bearing of main shaft casing, main shaft is connected with motor 9 by belt transmission secondary 8, the tapering coupling of the tapering of described spring chuck front end and pitch pattern hollow shaft front port, spring chuck passes pitch pattern hollow shaft, and its rear end is bolted with locking nut 10.Described pitch pattern hollow shaft cylindrical is provided with the screw thread with valve rod pitch coupling, described screw thread and pattern screw 11 engagements that are fixed on the frame, described pitch pattern hollow shaft two ends are slidingly connected with support 13 central axle sleeves 14 that are fixed on the frame upper slide rest 12, and described pitch pattern hollow shaft tail end is linked with feeding handle 15.Fixedly 2-4 is cutter 16 simultaneously for described cutterhead, and preferred four cutter, and four are fixed on cutter on the same degree of depth, and promptly the cutter constant depth is on the position of same center circle.
During operation, the workman is with the valve rod spring chuck of packing into, and the barre of trip lock jack panel with workpiece locking, shakes the feeding handle, pitch pattern hollow shaft along with the pattern screw screw advancement of its engagement, valve rod enters in the cutter of rotation and mills out screw thread.If the machining screw degree of depth of check is not enough, can radially adjust upper slide rest, make the milling depth of valve rod increase to the qualified degree of depth.
The above only is preferred embodiment of the present invention, is not structure of the present invention is done any pro forma restriction.Every foundation technical spirit of the present invention all still belongs in the scope of technical scheme of the present invention any simple modification, equivalent variations and modification that above embodiment did.
