Description

A kind of quick-clamping for creep test is extended device

Technical field

A kind of the utility model belongs to testing equipment field more particularly to quick-clamping for creep test is extended dress It sets.

Background technology

As novel metal, nonmetallic materials continually develop application, when high-volume is tested, the clamping speed for device of extending It is relatively slow, waste user's plenty of time.Tradition extend device by compared with multi-section dress form, it is complicated for operation so as to cause clamping, generally deposit It is cumbersome in clamping, operate clumsy problem, even if clamping it is fastest extend its time used of device cannot reach always User requires.Therefore, exploitation one kind can quick-clamping, the device of extending accurately measured is very necessary.

Invention content

The utility model provides a kind of quick-clamping for creep test and extends device, is filled with solving current generally existing It presss from both sides cumbersome, operates clumsy problem.

The technical scheme adopted by the utility model is that：Extended from above device, under device of extending form, above extend device under Apparatus structure of extending is identical, above extends device on the outside, under extend device in inside, wherein under the extend structure of device be：Under The lower snap ring of device of extending is connected with bar one end of extending under two with pin, is locked using tapered sleeve, under extend the bar other end under Bracket is connected, and grating sensor is installed on bottom bracket, small axis penetrates in bottom bracket while penetrating bearing washer, both ends are used with axis Baffle ring clamping bearing, four bearing outer rings are withstood on guide pipe positioning spigot, and left clamp arm, right clamp arm are noted using nylon material It is moulded into type, there are two pin holes thereon, are relatively large in diameter pin hole for connecting together two clamp arms, clamping will during pin wears pin Torsionspring penetrates, and in end shaft block ring by its clamping, and two clamp arms respectively penetrate two bottom bracket side rectangles In slot, left clamp arm, right clamp arm are hinged together with bracket by the smaller pin hole of diameter respectively by axis pin, and end is used with axis Baffle ring is by its clamping.

The utility model has the advantages that structure novel, above extends device on the outside, under extend device in inside, and same On axis, pass through simple operations, you can meet experiment matching requirements, the clamping speed greatly improved, efficiency is high, this is fast The exploitation that quick-mounting presss from both sides device of extending solves the problems, such as that clamping is slow-footed when high-volume is tested, and is that creep test area research is quick Development provides solid foundation.

Specific implementation mode

As shown in Figure 1, device 2 of being extended from above, under device 3 of extending form, device of above extending is extended apparatus structure phase under Together, above extend device 2 on the outside, under extend device 3 in inside, wherein under the extend structure of device 3 be：Under extend device 3 Lower snap ring 6 is connected with 8 one end pin 7 of bar of extending under two, is locked using tapered sleeve 5, in Fig. 1 under extend 8 other end of bar under Bracket 11 is connected, and grating sensor 4 is installed on bottom bracket 11, and small axis 18 penetrates in bottom bracket 11 while penetrating bearing gasket in Fig. 3 Circle 17, both ends 19 clamping bearing 16 of shaft block ring, four 16 outer rings of bearing are withstood on 9 positioning spigot of guide pipe, and guide pipe 9 is used It is fixed on jig main body 1 by screw 10 when clamping, left clamp arm 20, right clamp arm 22 are molded into using nylon material Type designs two pin holes thereon, is relatively large in diameter pin hole for connecting together two clamp arms；Clamping will during pin 21 wears pin Torsionspring 12 penetrates, and in end with shaft block ring 13 by its clamping, shown in Fig. 1, two clamp arms respectively penetrate two subiculums In 11 side rectangle slot of frame, left and right clamp arm 20,22 is hinged with bracket 11 by the smaller pin hole of diameter respectively by axis pin 14 To together, end is with shaft block ring 15 by its clamping；

For clamping process as shown in figure 3, extend device due under under, when clamping, should install down device of extending first, use hand Left clamp arm 20, right clamp arm 22 are pressed, bottom bracket 11 is flared out centered on 12 center line of torsionspring, and bottom bracket 11 is then The power opened is generated, extend under drive bar 8 and lower snap ring 6 open, and registration coupon is come up left clamp arm 20, right clamp arm 22, be locked tapered sleeve 5, at the same time four 16 freedom centerings of bearing, similarly, then device or so clamp arm end of extending in hand pressing, Can quick-clamping on jig main body 1, which, which primarily serves, connects together sample with testing machine loading system Effect, referring to Fig. 4.
