Abstract
The utility model discloses a spark -erosion wire cutting position measurement experiment special fixture that discharges, including the anchor clamps body, screw, trapezoidal cushion and steel ball. The anchor clamps bodies including top -down's a rectangle post hole, five rectangle post holes that the equidistance was arranged about horizontal, the threaded holes and long square groove that the equidistance was arranged about in the of five that the equidistance was arranged about in the of five, wherein long square groove is the clamping position of work piece, all post holes and screw hole intercrossing. The in -process of screw fastening in the system, steel ball produce horizontal drunkenness under the combined action of screw and trapezoidal cushion, the interior work piece of rectangle post pore pair recess that sees through top -down is exerted pressure, and then presss from both sides tight work piece. The utility model discloses satisfy the discharge special requirement of the used thin slice work piece clamping of position measurement experiment of spark -erosion wire cutting, realized in the experiment the simple and easy regulation of work piece altitude variation and rigidity to can a plurality of work pieces of while centre gripping when needs.
Description
Technical field
The utility model relates to electric spark linear cutting machine field, is specifically related to Wire EDM spark location detection experiment fixture.
Background technology
Current electric spark linear cutting machine is generally on universal fixturing, adopt pressing plate, screw clamping workpiece, but the clamping of the sheet parts that this installation way is special in detecting spark discharge position is also inapplicable, and can not accurately change the height of clamping workpiece, precision is difficult to ensure, complicated operation.
Utility model content
The utility model provides a kind of Wire EDM spark location detection experiment special fixture, meet the particular/special requirement that Wire EDM spark location detection tests slice work-piece clamping used, achieve the simple and easy adjustment that in experiment, workpiece height change and position are fixed, and multiple workpiece can be clamped when needed simultaneously.
The utility model is achieved through the following technical solutions: a kind of Wire EDM spark location detection experiment special fixture, comprises clamp body, screw, trapezoidal cushion block and steel ball.Described clamp body comprises a top-down rectangle post holes, transversely descends the screwed hole of five rectangle post holes of equidistant arrangement, about five equidistant arrangement and the rectangular recess of about five equidistant arrangement, wherein rectangular recess is the clamping position of workpiece, and all post holes and screwed hole intersect mutually.Described trapezoidal cushion block inserts five the rectangle post holes be arranged above and below, and contacts with the steel ball put into by screwed hole, and the screw that the two and screwed hole bolt enter forms clamping system jointly.In system screw fastening process in, steel ball produces horizontal looseness under the acting in conjunction of screw and trapezoidal cushion block, applies pressure through top-down rectangle post holes to the workpiece in groove, and then clamping work pieces.Charging-up lubricant oil is wanted, being that the horizontal looseness of steel ball is more prone in described screwed hole.Testing workpiece used is a series of rectangular sheet, with parallel jaw, this fixture is fixed on the table during experiment, clamping workpiece is carried out experiment measuring in the position of fixture bottom by first time experiment, and workpiece is adjusted to differing heights after terminating and measured by first time experiment successively.
Usefulness of the present utility model is: this fixture can locate the slice work-piece of clamp test given size, and workpiece can be adjusted to differing heights and carry out clamping, carry out clamping by the system of screw, trapezoidal cushion block and steel ball composition, easy and simple to handle, Stability Analysis of Structures is reliable.
Accompanying drawing explanation
Fig. 1 is Wire EDM spark location detection experiment special fixture schematic diagram.1 steel ball in figure, 2 is trapezoidal cushion blocks, and 3 is screws, 4 clamp bodies.
Detailed description of the invention: with reference to figure 1, the right-angle side of trapezoidal cushion block 2 is close to the square edge placement of the post holes on clamp body 4, steel ball 1 is put into by screwed hole, it is made to contact with the inclined-plane of trapezoidal cushion block, again screw 3 is screwed in screwed hole, along with the screw-in of screw 3, steel ball 1 is subject to the acting in conjunction of screw 3 and trapezoidal cushion block 2, produces horizontal looseness and makes it through the post holes workpiece pressing run through up and down on clamp body.
Claims (2)
1. a Wire EDM spark location detection experiment special fixture, in clamp body, several slice work-piece clamping grooves of equidistant arrangement in vertical direction, a top-down post holes, steel ball, trapezoidal cushion block and screw are installed successively, it is characterized in that: steel ball contacts with trapezoidal cushion block, screw contacts with steel ball, and rectangle post holes is left in clamp body and Workpiece clamping direction, and steel ball is under the extruding of screw, the downward play of steel ball can be made along post holes through groove upper plane, workpiece pressing.
2. Wire EDM spark location detection experiment special fixture according to claim 1, it is characterized in that: the groove that on clamp body, clamping workpiece is used is equidistant arrangement on clamp body height, workpiece can realize the clamping on differing heights.
