Abstract
The utility model discloses a fixing platform for material indentation tests. The fixing platform is mounted on a bidirectional screw rod inside a pool-type base, wherein the bidirectional screw rod rotates by passing through an overrunning clutch to be connected with a driving stem; due to rotation of the bidirectional screw rod, combination and dissociation of a left sliding end and a right sliding end can be achieved, and thus ensuring that a clamped tested material is always in the middle of the base and is right aligned to the part below a detection head of a testing machine; the left sliding end and the right sliding end are surrounded by the pool-type base and are provided with opposite tread tooth openings, thus ensuring that a test piece can obtain upward support force of the tread when being clamped and does not displace downwards when being stressed.
Description
Technical field
The utility model relates to stationary platform field, relates in particular to a kind of stationary platform for material indentation test.
Background technology
Existing material indentation test machine, need to be to stable being clamped in stationary platform of test material, and because testing machine belongs to highly sophisticated device, the detecting head of instrument is fixed position, when work, be the track that moves up and down, test material carried out to the tests such as the impression of different pressures.Therefore need the center of test material to be just in time positioned at the below of detecting head, aptitude test obtains objective material characteristic parameter like this.In addition, the stability requirement of test material on fixed station is higher, particularly to avoid because of the downforce of detecting head cause measured piece on fixed station to bottom offset.In addition the shape of material is various when current material impression test, is generally rod member, plate, column and excellent part are therefore higher to the fixing requirement of test block.
And it is existing for fixing platform, adopt the stationary platform setting of X-Y axle, although can solve like this ensure the core of test material be positioned at detecting head under problem, operate cumbersomely, most situations need adjustment fixed station after naked eyes judgement.In addition the end face of bare terminal end becomes plane counterpart clamping measured piece, and the problem to bottom offset that downforce is produced not can solve., easily there is certain displacement in particularly irregular testing part, affects test accuracy.
Utility model content
The utility model, in order to solve prior art problem, designs a kind of stationary platform for material indentation test.This platform solves test material and under detecting head downforce, produces the problem of displacement, and stable is fixed on below detecting head, and operates easy to use.
The technical solution of the utility model is: a kind of stationary platform for material indentation test, comprise pond type base, be arranged on the two-way leading screw in the type base of pond, on left-hand thread (LHT) on two-way leading screw and right-hand thread, there are respectively left sliding end and right sliding end, two-way leading screw is connected and is driven turning handle to rotate by overrunning clutch, left sliding end and right sliding end are surrounded by pond type base, and have relative tread tooth mouth, bottom to have the anti-plush copper that transfinites.
Preferred as one, two-way leading screw both sides have guide pole to pass described left sliding end and right sliding end.
Preferred as one, the central side of the front and rear wall of pond type base has tapped through hole, and described tapped through hole has thimble in succession by screw thread.
Preferred as one, drive turning handle can manually or connect motor and drive.
In sum, the beneficial effects of the utility model are:
1, the rotational of two-way leading screw is realized drawing close and separating of left sliding end and right sliding end, and ensures the test material middle part in base forever of clamping, is right against the detecting head below of test machine.Overrunning clutch can prevent from reversing, and plays the effect of pinning left sliding end and right sliding end, after stepping up, just can not get loose.
2, type base in pond surrounds left sliding end and right sliding end, does not need gathering sill or the guide pole also can Stable sliding can make left sliding end and right sliding end slide time.Particularly tooth mouth is tread, ensures that test block can obtain the upwards anchorage force of tread in the time of clamping, does not produce downward displacement when pressurized.
3, the central side of the front and rear wall of pond type base has tapped through hole, and described tapped through hole has thimble in succession by screw thread, can effectively assist clamping part to clamp some irregular test blocks.
Brief description of the drawings
Fig. 1 is the schematic diagram of a kind of embodiment of the utility model;
Fig. 2 is the A-A diagrammatic cross-section of Fig. 1.
Embodiment
As shown in Figure 1: a kind of stationary platform for material indentation test, comprise pond type base 1, be arranged on the two-way leading screw 2 in pond type base 1, one end of two-way leading screw 2 is fixing by fixture 21 through base outer wall, on left-hand thread (LHT) 24 on two-way leading screw 2 and right-hand thread 22, there are respectively left sliding end 32 and right sliding end 31, the other end of two-way leading screw 2 is connected to driving turning handle 8 after being arranged on the overrunning clutch 7 in type base 1 sidewall of pond, drives turning handle 8 can manually or connect motor and drives two-way leading screw 2 to rotate.When two-way leading screw 2 rotates, can realize drawing close and separating of left sliding end 32 and right sliding end 31, and ensure the test material middle part in pond type base 1 forever of clamping, be right against the detecting head below of test machine.When stepping up after measured piece, overrunning clutch 7 can prevent from reversing, and plays the effect of pinning left sliding end 32 and right sliding end 31, after stepping up, just can not get loose.Left sliding end 32 and right sliding end 31 are surrounded by pond type base 1, do not need gathering sill or the guide pole also can Stable sliding can make left sliding end 32 and right sliding end 31 slide time.And left sliding end 32 has relative tread tooth mouth with right sliding end 31, ensure that test block can obtain the upwards anchorage force of tread in the time of clamping, does not produce downward displacement when pressurized.The anti-plush copper 34 and 33 that transfinites is arranged respectively at left sliding end 32 and right sliding end 31 bottoms, add the polished rod portion 23 at two-way leading screw 2 middle parts, lean on mutually with 33 when the anti-plush copper 34 that transfinites, the slip that ensures left sliding end 32 and right sliding end 31 can not exceed corresponding thread segment and cause stuck.In embodiment, there is guide pole 61 and 62 two-way leading screw 2 both sides through left sliding end and right sliding end, for further stablizing the slip of left sliding end and right sliding end.
As shown in Figure 2: the central side of the front and rear wall of pond type base 1 has tapped through hole 40, described tapped through hole 40 has thimble 41 and 42 in succession by screw thread, thimble 41 and 42 has respectively tapered top 51 and 52, can effectively assist clamping part to clamp some irregular test blocks by rotating thimble 41 and 42.Make irregular test block can not produce the skew of front and back.
