Abstract

The invention relates to a test workpiece moving device for an electrical test table. The test workpiece moving device comprises a test working tabletop of the electrical test table. A sliding trolley device is fixedly connected to the tabletop and comprises two guide rails, sliding blocks, a flat trolley plate and an inclined block, wherein the two guide rails are fixedly connected to the working tabletop, two sliding blocks are arranged on each guide rail, the flat trolley plate is fixedly connected to the sliding blocks, the upper plane of the inclined block is of a V shape, the bottom face of the inclined block is a plane, and the inclined block is fixedly connected to the flat trolley plate. The test workpiece moving device has the advantages that due to the adoption of the sliding trolley device which is of a miniature linear guide rail structure, a workpiece can be made to freely move on the guide rails with less efforts; in addition, through the principle of tangency between the V-shaped groove face and the cylindrical surface and plates and blocks with different thicknesses, the height of the center of the workpiece can be quantitatively adjusted, manual calibration is not needed, and efficiency is relatively and greatly improved.

Description

Electrical test bench test piece mobile device

Technical field

The invention belongs to a kind of electrical test bench servicing unit, particularly relate to a kind of electrical test bench test piece mobile device.

Background technology

Current electrical test bench, workman often needs when travelling workpiece manually on work top, and restriction, particularly heavy workpiece (mutual inductor of for example 20kg) that workman's action is often subject to the various factorss such as the position size of miscellaneous part on height, width, length and the work top of work top often need to expend more manpower and time; Also have, for requiring strict fixture, (for example workpiece must be placed on ad-hoc location, and on this ad-hoc location, require the center line of workpiece to align with a certain particular line, and centerline is in a certain certain height), simple artificial placement often needs could realize several times, inefficiency.

Summary of the invention

The present invention provides one to increase work efficiency for solving the technical matters existing in known technology, reduces the electrical test bench test piece mobile device of workman's labour intensity.

The present invention for the technical scheme that solves the technical matters that exists in known technology and take is: it comprises and the test work top of described electrical test bench on described table top, is fixed with a sliding machine device; Described sliding machine device includes that two slide blocks on two guide rails and described every the guide rail thereof being fixed on described work top, one are fixed on the dolly flat board on described slide block, a upper plane is V font, and the skewback that bottom surface is plane, described skewback are fixed on described dolly flat board.

The present invention can also adopt following technical scheme: it also includes the identical coupling that is balanced against others of thickness and is placed in the plate in plane left and right sides on described skewback V font; The identical coupling that is balanced against others of described thickness is placed in the plate in plane left and right sides on described skewback V font can multiple different thickness.

Advantage and good effect that the present invention has are: owing to having adopted sliding machine device, use miniature linear guide rail structure, can make tested workpiece move freely on guide rail, freely park, greatly reduce workman's labour intensity as labor-saving tool; Utilize in addition the tangent principle of V font groove face and the periphery of skewback, specification the form of laying of tested workpiece, and the plate of different-thickness can regulate the height of tested workpiece centre quantitatively, need not manual calibration, before relatively improving, efficiency improves greatly.

And the advantage of miniature line slideway is: volume is little, lightweight, is particularly suitable for compact apparatus and uses; Positioning precision is high; Frictional resistance is little, loss is little, the life-span is long, can bear high-speed motion; Material stainless steel, rigidity is strong, can bear all directions load.

The advantage on the V font inclined-plane of skewback is: geometrically V-type inclined-plane just in time can be tangent with the periphery of various tested workpiece different-diameters, the stack that is simultaneously aided with several planks regulates, to ensure that the cylindrical axle center of each external diameter is on one of test board work top identical horizontal level.

Brief description of the drawings

Fig. 2 is that the general structure schematic diagram after tested workpiece is equipped with in the present invention on electrical test bench;

Fig. 3 is sliding machine device horizontal side structural representation on work top;

Fig. 4 is the tested axis of workpiece direction of annular when copper rod does not also stretch out in Fig. 2, structural representation of the present invention.

Embodiment

For further understanding content of the present invention, Characteristic, hereby exemplify following examples, and coordinate accompanying drawing to be described in detail as follows:

As shown in Figure 1,2,3, 4, be V font in the test of electrical test bench body 5 with having two slide blocks 9 on two miniature guide rails 2 and each miniature guide rail 2 thereof on work top 1, be fixed with plane on a dolly flat board 3, bottom surface is the skewback 4 of plane, and dolly flat board 3 is fixed on slide block 9.

The be balanced against others coupling that polylith different-thickness can be housed on skewback 4 is placed in the plate 10,11,12 in plane left and right sides on the V-arrangement of skewback 4.

The present invention, parameters for the V font inclined-plane of work top 1, guide rail 2, dolly flat board 3, skewback 4 can determine as the case may be, and on skewback 4, the quantity of the plank 10,11,12 of stack and thickness also will need to determine according to the parameter of skewback 4 with specifically.

Taking the tested workpiece of torus class as example, see Fig. 1, appearance when this is dolly unloaded workpiece, in figure, two miniature guide rail 2 tilings are fixed on the work top 1 of testing table, two miniature guide rail parallels are placed, form the track of dolly, determined the direction that dolly slides, its length has determined the stroke of dolly.

After dolly has loaded tested workpiece 8 and has been pushed into, as Fig. 2.For representing more intuitively the purposes of dolly, in figure, add the device example that detects workpiece, in figure, 6 and 7 is respectively two red copper bars, wherein copper rod 6 is upwards vertically to stretch out for 1 from work top after dolly pushes, the other end of the copper rod 7 parallel with work top 1 has the copper rod that is also perpendicular to work top 1 13 of a similar copper rod 6 to be attached thereto, all places in circuit of lower end of copper rod 13 and copper rod 6, and the two and the copper rod 7 formation path that communicates with each other, form the device that detects workpiece.

Operating personnel are placed on workpiece for measurement 8 on V-type skewback 4, then dolly are pushed to the work of can testing after station, meanwhile, operating personnel can be as required on guide rail random push-and-pull dolly.

In Fig. 4, be respectively three plank plates 10 that thickness is different, 11,12, its effect is: they are trapezoidal separately, be grouped together, on the basis of V font skewback 4, form several V font inclined-planes that rise for the time, padded tested workpiece 8 gradually, makes consistent alignment of axis of central axis with the copper rod 7 of tested workpiece 8; And for ensureing that the two central axis remains alignment, can be according to thickness and the quantity of the size adjustment plank of the restriction of actual conditions and workpiece 8 external diameters.
