Description

Combined type compartment bulb boring jig

Technical field

The utility model relates to mechanical, particularly a kind of combined type compartment bulb boring jig.

Background technology

As everyone knows, develop rapidly along with socioeconomic, auto industry is also advanced by leaps and bounds, and automobile miscellaneous is of a great variety, and is more and more favored by people as the van of automobile transportation; And add man-hour in the manufacturing in the combined type compartment of van, usually there is a following difficult problem, as shown in Figure 1, be the lamina tecti in combined type compartment, the schematic diagram that side carriage plate is connected with preceding railway carriage or compartment plate, A is that lamina tecti, B are that side carriage plate, C are that preceding railway carriage or compartment plate, D are bulb, when assembling, A, B, C parts all will meet on the bulb D with position degree accurately, specification requirement length tolerance ± 0.3mm, right angle diagonal error ± 0.3mm, top cover distortion unevenness error ± 0.5mm/m; For the combined type compartment that produces with pipeline system, for the assembling in the van-type compartment that will be fit to changeable light-duty and the heavy truck of various sizes, its length regular size reaches one, 2,000 kind; Especially the variation of car length causes difficulty very big, often adopt a plurality of large-scale location utensil correlated parts to be coupled to exactly on four jiaos the aluminium bulb D, once getting out five connecting hole E is also riveted, usually want the workman more than three to use manual type, bulb D at four jiaos, measure singly, operation such as contraposition, line, boring, gluing and riveted joint, become the bottleneck that streamline improves work efficiency, not only take a lot of work, time-consuming, but also cause a large amount of waste products, be badly in need of being improved.

The utility model content

The purpose of this utility model is to provide a kind of combined type compartment bulb boring jig, solved prior art take a lot of work, time-consuming and cause problem such as a large amount of waste products.

The technical solution of the utility model is: in order to guarantee a bulb and a left side, the bottom surface of right profile at grade, the boring mould must have these three part bottom surfaces of an energy standard at conplane base frame, respectively establish two boring jigs that can guide four spatial hole systems at two flanks of base frame, its external form is the swallow shape, adjust on the bulb, down, a left side, behind the right three-dimensional correct position, also need to design a hold-down mechanism efficiently, the fixed-site that mixes up is got off, by hold-down mechanism and with datum level is 3 balanced system of forces of the common composition of point of application three of another fulcrum and lever, just can guarantee unlikely upset of stressed member and dislocation, guarantee that the position of four pilot holes getting out is very accurate; Its structure is to be provided with part to be processed at conplane drill jig base frame, is provided with two boring locating templates at two flanks of base frame, and the boring locating template is swallow shape, respectively is provided with upper and lower two boring covers and four trip bolts on bore template; Below base frame, be provided with a benchmark panel, this benchmark panel with screw be fixed on base frame below, be provided with at the front end of benchmark panel and heighten bar, be provided with height-regulating device and lock-screw heightening the bar lower end; Be provided with hold-down mechanism in drill jig base frame rear end, this hold-down mechanism is made of lever, supporting base, fulcrum shaft, trip bolt, wherein supporting base is fixed on the base frame rear end with trip bolt, on supporting base, be provided with a fulcrum shaft, fulcrum shaft is run through in hole on the lever, be provided with lock-screw at lever rear end, lock-screw is provided with a spanner, and the support plane of lock-screw is the rear end face of benchmark panel; By the jig after the above-mentioned part assembling, with the lever is force application mechanism, by means of the fulcrum of heightening the accurate bulb of the pole pair back side, and to be that another fulcrum and the lever front end point of application are common with datum level form 3 balanced system of forces, guarantees that the position of four pilot holes getting out is very accurate.

Advantage of the present utility model is: simple in structure, move lightly, and the machining accuracy height, saves time at the saving of labor, improves the quality of products.
