Abstract
The utility model discloses a milling tool for an engineering van longitudinal beam. The milling tool comprises a bottom plate, a supporting frame, an ejection bolt and a locating block are arranged on the bottom plate, a locating spindle is arranged on the supporting frame, and a U-shaped pressing plate is arranged on the ejection bolt. Compared with the prior art, the milling tool has the advantages of being simple in structure, convenient to machine, novel in design, safe and reliable, quick in installing, clamping and locating, capable of guaranteeing machining accuracy of the longitudinal beam and improving work efficiency, and the like.
Description
Technical field
The utility model relates to a kind of milling and uses frock, particularly a kind ofly for milling of engineering truck longeron, uses frock.
Background technology
At present, the engineering truck longeron is a strength member on engineering truck, it is connected with crossbeam, jointly carrying the weight of whole vehicle body, this longeron belongs to welding structural element, its profile is just as streamlined boat, total length has 3m many, structure is comparatively complicated, on it, there are sipes and two groups of 2-M24 screwhole position dimension precision requirement of two 80mm higher, need on large-sized numerical control equipment, to process and just can reach requirement after assembly welding, because business capital is limited, can't be equipped with the numerical control device that can process longeron, existing method is that part is placed in to directly processing on plain-milling machine, the workpeople can only be with a lot of cushion blocks before processing, wedge, jack, bolt, the common tools such as pressing plate are fixed on longeron on platen, so consumed a large amount of time with manpower on clamping is proofreaied and correct, and not fixing reliable clamping mould also can cause part that loosening possibility is arranged in process, crudy can not get reliable assurance, the element precision processed is poor, produce a lot of waste products, to factory, cause very large loss, so prior art is still perfect not.
Summary of the invention
The purpose of this utility model is: provide a kind of simple in structure, practical, draw materials conveniently, the clamping location is quick, can guarantee that a kind of of longeron machining accuracy uses frock for milling of engineering truck longeron, to overcome the deficiencies in the prior art.
The utility model is constructed as follows: a kind ofly for milling of engineering truck longeron, use frock, comprise base plate, on base plate, be provided with bracing frame, puller bolt and locating piece, on bracing frame, be provided with positioning core axle, on puller bolt, be provided with " U " shape pressing plate.
On the end face of two of the left and right of base plate, be respectively arranged with two bracing frames.
On base plate, be provided with four locating pieces, between every two locating pieces, form the shape groove that can lay part.
On base plate, be provided with four puller bolts and the bolt hole that can insert puller bolt.
On positioning core axle, be provided with the locating platform that can make location, part left and right.
On bracing frame, be provided with the locating core axis hole that can insert positioning core axle.
Owing to having adopted technique scheme, at first will mill by frock and be fixed on workbench, then longeron is hung and milling with on the shape groove of frock, positioning core axle is penetrated in the hole on locating core axis hole and longeron again, then tighten puller bolt, compress the U-shaped pressing plate at two ends again, thereby longeron is fixed on firmly and mills recruitment and load onto, processing gets final product; Compared with prior art, the utility model not only has advantage simple in structure, easy to process, and design that ingenious, safe and reliable, clamping location is quick, the longeron machining accuracy that can guarantee, the advantage such as increase work efficiency.

The specific embodiment
The utility model is described in further detail below in conjunction with drawings and Examples.
Enforcement of the present utility model: a kind ofly use frock for milling of engineering truck longeron, comprise base plate 1, on base plate 1, be provided with bracing frame 2, puller bolt 3 and locating piece 4, on bracing frame 2, be provided with positioning core axle 5, on puller bolt 3, be provided with " U " shape pressing plate 6.
On the end face of two of the left and right of base plate 1, be respectively arranged with two bracing frames 2.
On base plate 1, be provided with four locating pieces 4, between every two locating pieces 4, form the shape groove 7 that can lay part.
On base plate 1, be provided with four puller bolts 3 and the bolt hole 8 that can insert puller bolt 3.
On positioning core axle 5, be provided with the locating platform 9 that can make location, part left and right, the setting of locating platform 9 assumes diamond in shape locating shaft, during clamping, makes it to longeron, be mainly the location, left and right.
On bracing frame 2, be provided with the locating core axis hole 10 that can insert positioning core axle 5.
During work, at first will mill by frock and be fixed on workbench, then longeron 11 is hung and milling with on the shape groove 7 of frock, again positioning core axle 5 is penetrated in the hole on locating core axis hole 10 and longeron, then tighten puller bolt 3, compress " U " shape pressing plate 6 at two ends again, thereby longeron is fixed on firmly and mills recruitment and load onto, processing gets final product.
This cover longeron has now completed the processing of many batches of parts, through follow-up investigation after milling and coming into operation by frock, its quality is fully qualified after check, and accurate to dimension is good, steady quality, the operator uses also convenient and swift, comparatively satisfied, simultaneously, the coming into operation of this frock, not only greatly shortened the clamping time of part, and make part location, compress more reliably, on original basis, further shortened process time of part, greatly improved the working (machining) efficiency of part.
