Abstract
The utility model discloses an electron beam welding work fixture for a small traveling wave tube slow-wave component. The electron beam welding work fixture comprises a left semicircular pressing block, a right semicircular pressing block, a fixed circular ring and a locating cylinder. The left semicircular pressing block is matched with the right semicircular pressing block to form a cylindrical pressing block, and the inner side of the cylindrical pressing block corresponds to the outer diameter of the slow-wave component. The fixed circular ring is sleeved on the cylindrical pressing block through threads in a connecting mode and fastens the cylindrical pressing block on the slow-wave component. The inner diameter of one end of the locating cylinder is bigger than that of the other end of the locating cylinder to form cone-shaped transition. The outer diameter of one end of the cylindrical pressing block is bigger than that of the other end of the cylindrical pressing block to form cone-shaped transition. The locating cylinder is sleeved on the cylindrical pressing block in a connecting mode to form tight fit of tapered slidable matching. A notch which is capable of enabling a window in the slow-wave component to pass through is arranged in the locating cylinder. The electron beam welding work fixture can enable the welding process to be convenient and fast, is suitable for mass production, can ensure that a position to be welded on a weldment can not deform in the welding process, and can also prevent the window from being collided or pressed to cause gas leakage and losses.
Description
Technical field
The utility model relates to electron beam welding equipment, is a kind of electron beam welding frock clamp of miniature TWT slow-wave component specifically.
Background technology
Travelling-wave tubes is a kind of microwave electrovacuum power device, mainly plays the final stage amplification in the microwave signal system, is widely used in the military and civilian field.Slow-wave component is the important composition parts of travelling-wave tubes, its parts are long, component part is many, weld seam is many, when welding, should guarantee good concentricity, the high vacuum air tightness is arranged again, therefore, be that slow-wave component is divided into two sections of input, outputs to the welding conventional method of slow-wave component, and then two sections are welded together, its welding process requirement is tighter, and the frock clamp of welding is the important prerequisite condition that guarantees its welding quality.At present two sections welded together generally all be the concentrated welding of adopting, but its inconvenient operation, weld interval is long, runs into the window of fragility easily because parts are long simultaneously in welding process and causes its gas leakage, so efficient is not high.For solving the slow-wave component Welding Problems, small-sized TWT slow wave component is adopted electron beam welding.
Summary of the invention
Technical problem to be solved in the utility model is, the concentrated electron beam welding frock clamp that changes electron beam welding into and a kind of miniature TWT slow-wave component is provided that welds of original TWT slow wave component, reach and both can make welding process convenient fast, the window that can guarantee weldment slow-wave component in welding process again can not run into fragile window easily and causes its gas leakage because of slow-wave component is long in welding process.
The realization the technical solution of the utility model is: a kind of electron beam welding frock clamp of miniature TWT slow-wave component, and it comprises left semicircle briquetting, right semi-circle briquetting, clamping rings, location cylinder; Inboard formation with the slow-wave component external diameter agrees with the cylindrical briquetting that described left semicircle briquetting and right semi-circle briquetting cooperate the back to form; Described cylindrical briquetting one end is provided with the external screw thread that matches with the internal thread of clamping rings, and described clamping rings is connected on the cylindrical briquetting by thread bush and simultaneously cylindrical briquetting is fastened on the slow-wave component; One end internal diameter of location cylinder forms tapering transition greater than other end internal diameter, and an end external diameter of described cylindrical briquetting forms tapering transition greater than other end external diameter, and described setting circle jacket casing is connected on and forms the tight fit that the tapering cunning is joined on the described cylindrical briquetting; Described location cylinder is provided with breach, and the window that this breach can hold on the slow-wave component passes through.
Described cylindrical briquetting internal diameter and the slow-wave component external diameter tolerance between the two is better than ± 0.05mm.
Breach on the cylinder of described location is an elongate in shape, avoids the long window that touches the slow-wave component fragility in welding process of slow-wave component to make slow-wave component gas leakage.
The beneficial effects of the utility model are: miniaturization slow-wave component electron beam welding frock, use said structure owing to adopting electron beam welding, compare with original technology, both can make welding process fast convenient, be very suitable for mass production, can guarantee that again weldment place to be welded in welding process is heated evenly and can not be out of shape, simultaneously because the loss that the utility model design jaggy and having reduced to a certain extent on the cylinder of location causes because of misoperation.Improved the welding efficiency of miniaturization slow-wave component.

The specific embodiment
As Fig. 1～shown in Figure 5: a kind of electron beam welding frock of miniature TWT slow-wave component, comprise by left semicircle briquetting 1, right semi-circle briquetting 2, clamping rings 3, the frock clamp that location cylinder 4 is formed, need the miniaturization slow-wave component 5 of welding to be arranged in two semicircle briquettings, in order to make the intact assembling of this several positions energy, at left semicircle briquetting 1, all be equipped with suitable screw thread on right semi-circle briquetting 2 and the clamping rings 3, location cylinder 4 internal diameters are then made certain conelet degree 9, one end external diameter of described cylindrical briquetting forms tapering transition greater than other end external diameter, and described location cylinder 4 is socketed in and forms the tight fit that the tapering cunning is joined on the described cylindrical briquetting.
Leaving a strip breach 8 on the described location cylinder 4, is that the window 7 on the miniaturization slow-wave component 5 that needs for convenience to weld can stretch out, and avoids running into window 7 or oppress window 7 causing distortion to cause gas leakage.
Carrying out the pre-installed timing of electron beam welding, the miniaturization slow-wave component 5 that need weld should be assembled earlier and finish, be fixed with left semicircle briquetting 1 and right semi-circle briquetting 2 then, cylindrical briquetting internal diameter that left semicircle briquetting 1 and right semi-circle briquetting 2 forms and the slow-wave component external diameter tolerance between the two is better than ± 0.05mm.The position of pushing down can be the input section, it also can be deferent segment, again clamping rings 3 is screwed on fastening in fact, to locate cylinder 4 at last is enclosed within on the circular briquetting, because two are all made certain tapering, so should join for sliding between them, be noted that at the sliding window 7 of joining in the process and want alignment notch 8, do not cause to break and cause leaking gas thereby bump to window 7.After the frock assembling is finished, put it in the sabot in the electron beam welding machine vacuum chamber, regulating in focus, weld seam 6 welds.
