Abstract
The invention provides a jig for fine material tension test, which comprises a lower squeeze head arranged on a basal body, and an upper squeeze head joggled with the lower squeeze head. The upper squeeze head is connected with a transmission mechanism. The transmission mechanism of the upper squeeze head comprises a rotary drum arranged on the basal body. The rotary drum is connected with a small shaft arranged axially inside the basal body. Upper ratchets are permanently connected with the rotary drum. Lower ratchets are tightly supported by a spring on the upper ratchets. Keys of the lower ratchets are arranged in the axial sliding chutes of the small shaft; the small shaft is connected with a spigot shaft through thread. The spigot shaft is connected with the basal body in an axial gliding way. The upper squeeze head is permanently connected with the spigot shaft. The screw-in direction is the same with the driving direction of the friction of the ratchet transmission pair. The invention has the advantages of simple and sound structure, few parts, capability of adequately protecting fine materials from being pinched off in test, clamping samples easily and adjustable clamping force.
Description
(1) technical field
The present invention relates to employed anchor clamps in the measuring technique, relate in particular to a kind of anchor clamps that are used for the fine material tension test.
(2) technical background
Microelectronic chip has been widely used in fields such as national defence, medical treatment, Aero-Space, automobile, nowadays people no longer are satisfied with the realization of some systemic-function, but pay close attention to problems such as the stability of the optimal design of microelectronic chip and work thereof and reliability more.During the microelectronic chip encapsulation, the main method that realizes the electrical interconnection of chip is a wire bond, have every year to surpass 4,000,000,000,000 wire bond solder joint generation, this has just proposed new requirement to the mechanical property detection of silk thread materials such as the used Au of microelectronic chip electrical interconnection, Ag, Al, Cu with failure mechanism.At present when measuring the tensile mechanical properties of silk thread sample, the silk thread tensile test fixture that domestic and international testing machine factory provides adopts wound form usually, as shown in Figure 1, this anchor clamps are applicable to the silk thread of big (general diameter is greater than 1mm) of diameter, but (general diameter is 10～1002m), (Breaking load is generally 0.1～10N) in easy fracture because the specimen size of silk threads such as the used Au of microelectronic chip electrical interconnection, Ag, Al, Cu is little, traditional stretching clamp can not satisfy its requirement, therefore presses for and designs the silk thread tensile test fixture that can satisfy above-mentioned requirements.
(3) summary of the invention
In order to solve being unsuitable for of existing tensile test fixture, the invention provides a kind of being suitable for to minute diameter, the easy disrumpent feelings silk thread sample anchor clamps that carry out tension test to minute diameter, the easy deficiency tested of disrumpent feelings silk thread sample.
The present invention adopts following technical scheme:
A kind of anchor clamps that are used for the fine material tension test comprise the push-down head that is arranged on the matrix, seaming chuck and push-down head engagement, and described seaming chuck connects a gear train; Described seaming chuck gear train comprises: be installed in the tube that revolves on the matrix, the described tube that revolves connects an axial arranged little axle that is arranged on matrix inside, last ratchet with revolve the tube affixed, following ratchet is pushed against on last ratchet by spring, the key of following ratchet is arranged in the axial slide of little axle, described little axle and sleeve are by being threaded, described sleeve can be connected axially slidably with matrix, described seaming chuck and sleeve are affixed, and the precession direction of described screw thread is consistent with the friction force transmission direction of described ratchet transmission.
Further, described little axle is provided with the shaft shoulder, and the shaft shoulder cooperates with briquetting on the matrix.
Further, described push-down head region of engagement is a fluted column shape, and described seaming chuck region of engagement is the dome cylindricality, described seaming chuck region of engagement surface coverage one rubber layer.
Principle of work of the present invention is: when carrying out the tension test of fine material, the fine material sample is placed the fluted column shape region of engagement of push-down head, be rotated in the forward and revolve tube, revolving the last ratchet of tube drive just changes, last ratchet drives ratchet rotation down by friction force, and following ratchet rotates by the little axle of effect drive of key, and little sleeve that promotes to be threaded with it of rotation moves downward, make seaming chuck and push-down head mesh, thereby clamp the fine material sample.Revolve tube and continue to be rotated in the forward, when causing the fine material holding force to reach certain certain value, its resistance makes that going up ratchet skids with following ratchet, thereby the sample that has guaranteed fine material is unlikely destroyed.After experiment finishes, tube is revolved in reverse rotation, revolve tube and drive upward ratchet counter-rotating, the direct engagement of the claw by last ratchet and the claw of following ratchet, drive ratchet counter-rotating down, little axle is backward rotation thereupon also, and the sleeve that the little axle pulling of rotation is threaded with it moves upward, thereby seaming chuck and push-down head disengaging are come.
Beneficial effect of the present invention is: simple and reasonable, number of spare parts is few, the very thin test that can adequately protect not by pinch off, the sample clamping is easy, holding force is adjustable.

(5) embodiment
The present invention is described further below in conjunction with accompanying drawing.
With reference to accompanying drawing: a kind of anchor clamps that are used for the fine material tension test, comprise the push-down head 2 that is arranged on the matrix 1, seaming chuck 3 connects a gear train with push-down head 2 engagements, described seaming chuck 3; Described seaming chuck gear train comprises: be installed on the matrix 1 revolve the tube 4, the described tube 4 that revolves connects an axial arranged little axle 5 that is arranged on matrix 1 inside, last ratchet 6 is with to revolve tube 4 affixed, following ratchet 7 is pushed against on last ratchet 6 by spring 8, the key of following ratchet 7 is arranged in the axial slide of little axle 5, described little axle 5 and sleeve 9 are by being threaded, described sleeve 8 can be connected axially slidably with matrix 1, described seaming chuck 3 is affixed with sleeve 9, and the precession direction of described screw thread is consistent with the friction force transmission direction of described ratchet transmission.
Described little axle 5 is provided with the shaft shoulder 10, and the shaft shoulder 10 cooperates with briquetting 11 on the matrix 1.
Described push-down head 2 region of engagements are fluted column shape, and described seaming chuck 3 region of engagements are the dome cylindricality, described seaming chuck 3 region of engagement surface coverage one rubber layer.
