Description

The liquid storing barrel welding machine

Technical field

The utility model relates to a kind of small-sized use in refrigerator cold-producing medium liquid storing barrel welding machine.

Background technology

Diffusion absorption type refrigeration system is mainly used in small refrigerator, and this refrigeration system does not have compressor, does not also adopt freon as refrigeration machine, is cold-producing medium but adopt ammonia, and water is absorbent, and inert gas is as diffusant; Ammonia and water generally are sealed in the liquid storing barrel, and liquid storing barrel is cylindrical, mostly are two cylindrical halfbody opening parts butt joints and are welded, and then inject ammonia and water in the good liquid storing barrel of welding; Existing liquid storing barrel welding does not have specialized apparatus, the method that adopts be earlier with two halfbodies to connecting, along diameter spot welding is carried out in the slit between two halfbodies then, weld 2 points, a halfbody with the anchor clamps clamping then and rotating again and carry out butt welding along the complete cycle slit, firm until seal welding.The problem that said method exists is that operating efficiency is lower, the easy clamping shakiness of anchor clamps, and rotate underaction, and some does not have the slit in the place of discovery to can not get seal welding, has caused the reduction of welding quality, and product percent of pass is also lower.

Summary of the invention

The rotation that the utility model has existed when mainly having solved liquid storing barrel welding in the prior art is dumb, welding efficiency is low, the technical problem that product percent of pass is low, liquid storing barrel rotated flexibly when a kind of some postwelding butt welding was provided, and is convenient and reliable, can increase work efficiency and the liquid storing barrel welding machine of welding quality.

The technical solution of the utility model is achieved in that the liquid storing barrel welding machine, this welding machine comprises frame, main shaft, be used for fixing the liquid storing barrel sleeve that liquid storing barrel also can hold not a half liquid storing barrel, drive sprocket, driven sprocket, the drive unit that is connected with drive sprocket, and with initiatively, the chain that driven sprocket is meshed, described frame is made of base and vertical rod, and main shaft is arranged on the top of vertical rod, driven sprocket is fixedly mounted on the main shaft, liquid storing barrel sleeve along continuous straight runs is installed in the end of main shaft, and the vertical rod bottom is provided with axle sleeve, and drive sprocket is fixedlyed connected with the little axle in being inserted into axle sleeve.

As preferably, described drive unit includes crank, and an end of crank is provided with rocking handle, and the other end of crank is fixedlyed connected with the drive sprocket center.Thus, can adopt the mode of hand rocking handle or foot-operated rocking handle to drive the drive sprocket rotation.

As preferably, described driven sprocket is a single direction ratchet.Thereby having limited driven sprocket can only rotate by unidirectional drive main shaft.

As preferably, drive sprocket is connected with the resetting-mechanism that can return to original position after self being subjected to rotating in order to the power of ordering about the drive shaft rotation again.Thus, when power that rocking handle is applied drives the drive sprocket rotation, the main axis rotation certain angle, manually the slit of the liquid storing barrel joint on the liquid storing barrel sleeve is welded with convenient, drive sprocket rotates the back and resets under the effect of resetting-mechanism, because the effect of single direction ratchet, main shaft does not reset to opposite spin, at this moment, driving drive sprocket once more makes main shaft continue rotation, main shaft rotates to an angle again, in face of Han Jie slit is not emerging in again, can continue this part slit is welded, main shaft is done the batch (-type) rotation and is rotated to drive liquid storing barrel under the effect of resetting-mechanism, personnel weld it with convenient working, rotate more flexibly, and operating efficiency and welding quality also improve greatly.

As preferably, described resetting-mechanism includes a link position makes chain have the tensioner of the direction of motion opposite with the main axis rotation direction.

As preferably, an end of described tensioner connects base, and the other end of tensioner connects chain.

As preferably, described tensioner is extension spring.

As preferably, the vertical rod top is provided with a spindle carrier, and the two ends of spindle carrier are provided with two arc grooves, and respectively along being circumferentially with the stopper slot that is complementary with arc groove, main shaft is installed on two arc grooves by stopper slot on the lateral surface of main shaft two ends.Because the effect of stopper slot makes that main shaft can be along circumferentially rotating but can in axial direction not be moved.

As preferably, the end of main shaft is provided with external screw thread or internal thread, and the liquid storing barrel sleeve is connected with spindle thread.

As preferably, spindle carrier is provided with liquid storage sleeve fixed head, vertically is fixed with a liquid storing barrel sleeve on liquid storage sleeve fixed head.The purposes of above-mentioned liquid storing barrel sleeve is to be used to dock the liquid storing barrel halved body spot welding of going forward side by side.

Principle of the present utility model and advantage are: the utility model adopts chain gear transmission, the liquid storing barrel of a postwelding can be inserted in the liquid storing barrel sleeve, shaking rocking handle then makes the sprocket wheel rotation drive the main shaft rotation, make liquid storing barrel also rotate thereupon, thereby can weld the slit of liquid storing barrel joint easily comprehensively, rotate more flexibly, operating efficiency and welding quality also improve greatly.Further, driven sprocket adopts single direction ratchet; rocking handle can adopt foot-operated mode to drive; the resetting-mechanism that connects on the chain can make that drive sprocket resets after rotation; because the effect of single direction ratchet; main shaft does not reset to opposite spin; at this moment, drives drive sprocket once more and makes main shaft continue rotation, and main shaft rotates to an angle again; Han Jie slit is not emerging in face of the operating personnel again; thus can continue this part slit is welded, main shaft is done the batch (-type) rotation and is rotated to drive liquid storing barrel under the effect of resetting-mechanism, and personnel weld it with convenient working; hommization more, save operating personnel's muscle power greatly.
