Abstract
The utility model discloses a rocker-arm hole turning tool fixture. The rocker-arm hole turning tool fixture comprises a bottom board support, a supporting frame, a compression bolt, a locating spline bolt and a spline locating shaft, wherein the supporting frame abuts against the bottom board support, the spline locating shaft is fixed on the bottom board support through the locating spline bolt, and the compression bolt enables a rocker arm to be machined to be fixed on the bottom board support. The rocker-arm hole turning tool fixture has the advantages of being high in working efficiency and stable in machining quality.
Description
Technical field
The utility model belongs to technical field of tooling clamps, specifically, and particularly a kind of rocking arm hole turning machining tool fixture.
Background technology
Along with the fast development of modern project machinery, rocking arm has obtained extensive use in engineering machinery.Along with the rapid increase of market to the rocking arm demand, more and more higher requirement has been proposed for crudy and the working (machining) efficiency of rocking arm.
In the prior art, mainly be to use by boring machine existing pre-manufactured hole on the rocking arm is carried out boring processing.The boring machine machining accuracy is higher, the rocking arm steady quality of processing, but exist work efficiency lower, can't satisfy requirement of mass production.Simultaneously, need centering to aim at pre-manufactured hole in the boring machine processing, may introduce human error, and the boring machine price is bigger, for processing producer, the investment amount height that needs.Lathe is mainly with lathe tool the workpiece that rotates to be carried out the lathe that turning is processed, and have the good advantage of working (machining) efficiency, but lathe carries out the man-hour that adds of hole part, is not suitable for the location to irregular workpiece.
Therefore, providing a kind of rocking arm hole turning machining tool fixture that can carry out rocking arm hole processing at lathe is the technical problem that those skilled in the art need solution badly.
?
The utility model content
The purpose of this utility model provides a kind of stable processing quality and the high rocking arm hole turning machining tool fixture of working (machining) efficiency.
To achieve these goals, the utility model provides a kind of rocking arm hole turning machining tool fixture, comprise mount holder, supporting bracket, hold-down bolt, location spline bolt, spline locating shaft, described supporting bracket is resisted against on the described mount holder, on described mount holder, described hold-down bolt is fixed in rocking arm to be processed on the described mount holder described spline locating shaft by described location spline bolting.
Preferably, also comprise casting die plate group, described hold-down bolt is pressed on the casting die plate in the described casting die plate group on the plane of rocking arm to be processed.
Preferably, described casting die plate group comprises the first casting die plate and the second casting die plate.
Compared with prior art, rocking arm provided by the utility model hole turning machining tool fixture, rocking arm to be processed is positioned on the mount holder, support by supporting bracket, and by the spline locating shaft splined hole of rocking arm to be processed is processed the location, behind the location, undertaken fastening by location spline bolt; Can rocking arm to be processed be carried out the plane by the casting die plate and step up, and be undertaken fastening by hold-down bolt; Use two blocks of casting die plates can obtain the good effect that compresses.
In sum, by using rocking arm provided by the utility model hole turning machining tool fixture, can replace the mode of bore hole that the rocking arm hole is processed by the processing mode of turning, and have advantages such as working (machining) efficiency height and stable processing quality.
Description of drawings
Fig. 1 is the structural representation of a kind of embodiment of a kind of rocking arm hole turning machining tool fixture that the utility model proposes.
The specific embodiment
The purpose of this utility model provides the rocking arm hole turning machining tool fixture of a kind of working (machining) efficiency height and stable processing quality.
In order to make those skilled in the art understand the technical solution of the utility model better; below in conjunction with accompanying drawing the utility model is described in detail; the description of this part only is exemplary and explanatory, should any restriction not arranged to protection domain of the present utility model.
Please refer to Fig. 1, in one embodiment, a kind of rocking arm hole turning machining tool fixture provided by the utility model, comprise mount holder 1, supporting bracket 2, hold-down bolt 3, location spline bolt 4, spline locating shaft 5, with casting die plate group, described casting die plate group comprises the first casting die plate 6 and the second casting die plate 7, described supporting bracket 2 is resisted against on the described mount holder 1, described spline locating shaft 5 is fixed on the described mount holder 1 by described location spline bolt 4, and described hold-down bolt 3 is pressed on the first casting die plate 6 in the described casting die plate group and the second casting die plate 7 on the plane of rocking arm to be processed and with rocking arm to be processed and is fixed on the described mount holder 1.
Use the flow process of above-mentioned rocking arm hole turning machining tool fixture as follows:
At first mount holder 1 is contained on the chuck of lathe; Rocking arm to be processed is positioned on the mount holder 1, supports by supporting bracket 2, and process the location by the splined hole of 5 pairs of rocking arms to be processed of spline locating shaft, behind the location, undertaken fastening by location spline bolt 4; Can rocking arm to be processed be carried out the plane by the first casting die plate 6 and the second casting die plate 7 and step up, and be undertaken fastening by hold-down bolt 3.
Use above-mentioned rocking arm hole turning machining tool fixture to adopt turning processing, replace boring machine bore hole processing of the prior art, each common laborer every day can be by 5 in processing rocking arm hole, increase to 18 in processing rocking arm hole, improve nearly 4 times of work efficiency, simultaneously owing to avoided processing the human error that centering causes, crudy temperature, significantly reduced processing cost, improved output, economic benefit is obvious.
Need to prove; the utility model does not limit the quantity of the installation site of first cradle member that arranges on the floor piece; can be two; also can be more than two; therefore; in order to adapt to the rocking arm to be processed hole processing of different length, in floor piece the installation site of a plurality of first cradle members is set, all should be within the utility model protection domain.
Need to prove, in this article, relational terms such as first and second grades only is used for an entity or operation and another entity or operation are made a distinction, and not necessarily require or hint these entities or the operation between exist any this reality relation or the order, and, term " comprises ", " comprise " or its any other variant is intended to contain comprising of nonexcludability, thereby make the process that comprises a series of key elements, method, which key element article or equipment not only comprise, but also comprise other key elements of clearly not listing, or also be included as this process, method, the key element that article or equipment are intrinsic.Do not having under the situation of more restrictions, the key element that is limited by statement " comprising ...
