Abstract
The utility model relates to a device for assisting the welding of an axle accessory, which comprises an axle welding platform, an axle accessory fixing device and a supporting bridge, and also comprises a screw rod, two rolling linear track pairs and an axle accessory positioning benchmark platform which are installed on the axle welding platform. The axle accessory positioning benchmark platform is movably connected with the axle welding platform, so the flexibility is improved. The device unifies the positioning benchmark of all accessory tools, and adopts a balance crane to directly hoist workpieces into the tool so as to complete the assembling at one step, so the labor intensity is reduced, and the welding precision is improved.
Description
Technical field
The utility model relates to a kind of device of vehicle bridge welding, particularly a kind of device of auxiliary vehicle bridge annex welding.Belong to automotive field.
Background technology
The annex welding tooling that uses aborning is equipped with a special tooling for each parts at present, there is variety of issue in location benchmark between frock and the frock, the location benchmark difference between the annex frock for example, there are cumulative errors in connecting each other between frock and frock, and each annex frock upper and lower pieces needs manual operations to increase labour intensity etc.Waste time and energy, welding precision is also not high.
Summary of the invention
At the deficiencies in the prior art, technical problem to be solved in the utility model is to provide a kind of device of auxiliary vehicle bridge annex welding, and labour intensity is big when operating in order to solve, the not high problem of welding precision during welded attachment.
For solving the problems of the technologies described above, the technical scheme that the utility model is taked is, a kind of device of auxiliary vehicle bridge annex welding, comprise vehicle bridge jig, vehicle bridge annex fixture and supporting bridge, also include leading screw, two linear rolling guides and vehicle bridge annex location reference platform in this device, be installed on the vehicle bridge jig.
The device of above-mentioned auxiliary vehicle bridge annex welding, leading screw is connected with vehicle bridge annex location reference platform; Leading screw adopts the trapezoidal thread structure.
The device of above-mentioned auxiliary vehicle bridge annex welding, vehicle bridge annex location reference platform and vehicle bridge jig flexibly connect.
This device is with the location benchmark of each annex frock, unite by vehicle bridge annex location reference platform, and adopted two guide rails, the structure that vehicle bridge annex location reference platform and vehicle bridge jig flexibly connect has alleviated labour intensity and has improved flexibility ratio and welding precision.
Description of drawings
Fig. 1 is the apparatus structure schematic diagram of auxiliary vehicle bridge annex welding.
The specific embodiment
With linear rolling guide 1, be installed on the vehicle bridge jig during work; With vehicle bridge annex location reference platform 2, be connected with linear rolling guide 1 by slide block; The annex frock is installed on the reference platform 2 of vehicle bridge annex location; Leading screw 3 is installed on the vehicle bridge jig and with vehicle bridge annex location reference platform 2 and is connected.After using leading screw 3 to adjust the wheelspan that needs, supporting bridge 4 is hung annex positioner in the annex frock, putting into needs welded attachment, welds after using anchor clamps to fix annex.
This device has adopted two linear rolling guides that frock is carried out accurate axial location, because when using guideway in pairs, have " error homogenising effect " and reduced processing request, under the prerequisite that cuts down finished cost, satisfied required precision the guide rail installed surface.And the type guide rail can be controlled steering error≤0.35mm in the 4000mm length range, can reach the accurate location to weldment.
The lead screw transmission that adopts this device realizes the supporting bridge annex welding of free of discontinuities wheelspan, leading screw adopts trapezoidal thread, there is equal radial clearance at the big footpath and the path place of this screw thread pair, the intensity height, the good manufacturability of screw thread is interiorly fitted with the conical surface for screw thread, and is good to neutrality, be difficult for becoming flexible driving force that the application in frock can provide and transmission accuracy.Adapt to market more flexibly to identical product but the demand of the different vehicle bridge of wheelspan has reduced life cycle of the product, improved competitiveness of product.
This device adopts a plurality of annex frocks to locate the mode of different benchmark respectively.Because the complexity of frock and heavy quality in the former technology, be easy in long-time production, cause the frock precision to reduce, and the operation deviation that causes greatly owing to labour intensity, in the utility model, a plurality of appendicle frocks are adopted same location benchmark, not only reduced owing to the location benchmark cumulative errors that cause more, but also reduced the complexity of frock, originally complicated frock is resolved into simple little frock, not only made things convenient for frock making to reduce cost of manufacture but also reduced technical ability requirement the operative employee.
The utility model gets up the location unifying datum of each annex frock, and upper and lower pieces has adopted balance crane directly to hang to get workpiece to put into clamping of frock to finish, alleviated labour intensity and improved welding precision.
Above-mentioned explanation is not to be to restriction of the present utility model; the utility model also is not limited to above-mentioned giving an example, and those skilled in the art are in essential scope of the present utility model; the variation of making, remodeling, interpolation or replacement all should belong to protection domain of the present utility model.
