Abstract
The invention provides a lathing clamp for machining prismatic parts. The lathing clamp comprises a clamp body, wherein the clamp body is of an annular cylinder, a blind hole is formed in the upper end surface of the cylinder, the shape of the blind hole is matched with that of a diamond-shaped filling pressure plate, and the center of the blind hole is coincided with the center of the cylinder; an opening is formed in the side wall of the cylinder along the radial direction, and a groove is formed in the inner wall, symmetric with the opening, of the cylinder. According to the lathing clamp for machining the prismatic parts, by virtue of a principle that the self-centering is realized when the cylinder is clamped by virtue of three claws, an opening of a tool clamp deforms to clamp workpieces by virtue of clamping forces of the three claws, so that the clamping is convenient, the center of the filling pressure plate can be accurately and rapidly aligned, and the machining precision and efficiency are guaranteed.
Description
Technical field
The present invention relates to clamping tool for machine work technical field, particularly relate to a kind of car of processing prism shape partFixture.
Background technology
At valve industry, hold-down grid almost every valve products all will use, and large in batches, specification has tensMore than kind, each specification profile is all inconsistent, so being widely used of hold-down grid becomes a kind of standardPart, its standard No. is JB/T5207-1991, it is 12.5 that hold-down grid requires endoporus roughness in standard, endFace has an annulus sphere, and it is 3.2 that annulus sphere requires surface roughness. In process of production, because of hold-down gridFor diamond-shaped component, part blank is foundry goods, and endoporus and end face need processing, and the second operation is processing antiplaneWith annulus sphere, this operation will be used the center of chuck centering diamond-shaped component on lathe, due to work endThe facial plane depth of parallelism and endoporus center axiality have requirement, so chuck centering center is very difficult, and endThe facial plane depth of parallelism and endoporus center axiality are also difficult to ensure.
Summary of the invention
Technical problem to be solved by this invention is: in order to overcome available technology adopting chuck centering water chestnutThe center difficulty of shape part and end face plane parallelism and endoporus center axiality are also difficult to the deficiency ensureing,The invention provides a kind of vehicle clamper of processing prism shape part.
The present invention solves the technical scheme that its technical problem will adopt: a kind of car of processing prism shape partFixture, comprises chuck body, and described chuck body is annular cylinder, the upper surface of described chuck bodyBe provided with blind hole, the form fit of the shape of described blind hole and rhombus hold-down grid, and the center of blind hole and fixtureThe center superposition of body, radially has a gap on the sidewall of described chuck body, and with described gap pairThe cylinder inwall claiming is provided with a groove.
Adopt the self-centering principle of three-jaw folder cylinder, realize and clamping by diminishing gradually of gap, at gapDwindle rear inwall is produced to compression, and with the position deflection maximum of gap radial symmetric, produce oppositelyPower, impact clamp, therefore, on inwall, be provided with groove with the position of gap symmetry, ensure inwall do not produceRaw stress, thus clamping ensured.
Preferably, described gap and described groove are located at the two ends, slotted hole footpath of described blind hole. This position gapWith the distance maximum of groove, the power minimum needing when clamping, clamps better effects if under identical stress condition.
Further, due to the jagged situation in the edge of rhombus workpiece to be processed, between burr and blind hole edgeProduce gap, affect stepping up of workpiece, therefore, described blind hole bottom circumference is provided with the slot to make way of outside depression.By being provided with the slot to make way of outside depression, can effectively hold burr, burr is entered in slot to make way, therebyRealize the clamping of workpiece.
Further, described chuck body is provided with on the excircle of end face of blind hole one side and is equipped with locating flange.Axial location when being realized three-jaw and stepped up by flange, ensures the uniformity of clamped position.
When concrete use, press from both sides cylindrical lateral surface with three-jaw, and near the end face of the locating flange on cylindrical,Load onto hold-down grid, tighten three-jaw, thereby utilize the clamping force of three-jaw that the gap distortion on fixture is clampedHold-down grid.
The invention has the beneficial effects as follows: a kind of vehicle clamper of processing prism shape part provided by the invention, this folderTool utilizes the self-centering principle of three-jaw folder cylinder, and the accurately center of fast aligning hold-down grid, ensuresThe efficiency of machining accuracy and processing; Thereby the clamping force of utilizing three-jaw causes the distortion of frock clamp gap to clampWorkpiece, convenient mounting and clamping; Utilize slot to make way to avoid burr on the impact clamping, further improved processing essenceDegree.

Detailed description of the invention
The present invention is described in detail by reference to the accompanying drawings now. This figure is the schematic diagram of simplifying, only with the side of signalFormula illustrates basic structure of the present invention, and therefore it only shows the formation relevant with the present invention.
As Figure 1-3, a kind of vehicle clamper of processing prism shape part of the present invention, comprises chuck body 1,Chuck body 1 is annular cylinder, and the upper surface of chuck body 1 is provided with blind hole 2, the shape of blind hole 2 withThe form fit of rhombus hold-down grid, and the center superposition of the center of blind hole 2 and chuck body 1, fixture originallyOn the sidewall of body 1, radially have a gap 3, and be provided with one with chuck body 1 inwall of gap 3 symmetriesGroove 4. Preferably, gap 3 and groove 4 are located at the two ends, slotted hole footpath of blind hole 2.
As shown in Figure 3, due to the jagged situation in the edge of rhombus workpiece to be processed, burr and 2 ends of blind holePortion produces gap between edge, affects stepping up of workpiece, and therefore, blind hole 2 bottom circumference are provided with outside depressionSlot to make way 5. By being provided with the slot to make way 5 of outside depression, can effectively hold burr, burr is entered and allowIn the groove of position 5, thereby realize the clamping of workpiece. Chuck body 1 is provided with on the excircle of end face of blind hole 2 one sidesBe equipped with locating flange 6. Axial location when being realized three-jaw and stepped up by locating flange 6, ensures clamped positionUniformity.
When concrete use, use the lateral surface of three-jaw clamping device body 1, and near the locating flange 6 on cylindricalEnd face, load onto hold-down grid, tighten three-jaw, utilize the clamping force of three-jaw that the gap 3 on fixture is becomeThereby shape clamps hold-down grid.
Taking above-mentioned foundation desirable embodiment of the present invention as enlightenment, by above-mentioned description, relevant workDo personnel and can, not departing from scope of the present invention, carry out various change and amendment completely. Send out for thisBright technical scope is not limited to the content on description, must determine it according to claim scopeTechnical scope.
