The special chuck can clamp the nonstandard bolt sample conveniently.
Description
Technical field
The utility model relates to a kind of non-standard latch sample special carrier, is used for the clamping of implant test to sample.
Background technology
Implant test is the test method of assessment Metal Material Welding crackle tendency, test needs base plate and pole shape latch sample, boring (diameter equates with the latch specimen finish) on the base plate, latch sample one end is inserted in the hole of base plate, end face is concordant with backplate surface, the sample other end is clamped by chuck, one weld seam of built-up welding on base plate, weld seam is through the hole on the base plate and with the certain degree of depth of sample end face fusing, by load maintainer and chuck sample is loaded then, with the crackle tendency of this experimental material.
The latch sample of standard is a pole shape sample, and diameter is 8mm, and an end is processed into screw thread, and existing clamping mode is that screw thread is screwed in the screw socket in the chuck, is connected with chuck by screw thread, reaches the purpose of clamping.For the non-standard latch sample in " a kind of non-standard latch sample " patent of inventor herein's application, diameter is 3mm-6mm, because specimen size is little, be processed into the engage thread insufficient strength of sample afterwards own, break at the screw thread place during loading easily, therefore can not adopt the mode of screw thread to connect.
The utility model content
Technical problem to be solved in the utility model provides a kind of special carrier that can clamp non-standard latch sample.
The utility model solves its technical matters and adopts following technical scheme:
The utility model comprises the connection base, straight sleeve fixedly connected and the wedge shape sleeve of fixedlying connected with straight sleeve with being connected base, be set with the pull bar that can in straight sleeve, move up and down in the described straight sleeve, between pull bar and straight sleeve, be provided with spring, be set with handle on the pull bar, the described wedge shape sleeve lining guide-track groove that has been inclined to set, in the wedge shape sleeve, be provided with slide block, slide block is provided with fixture block, slide block is provided with limit guide rail, limit guide rail is embedded in the guide-track groove and can slides up and down along guide-track groove, described slide block lower end is connected with the pull bar upper end, pulls on handle down, and pull bar drives slide block and moves down along guide-track groove.
Be inclined to set three in the described wedge shape sleeve be mutually 120 ° be centrosymmetric guide-track groove with wedge shape sleeve center.
Handle is set with down handle on the correspondence of described connection base two ends.
The lower end of described slide block is provided with the boss that is embedded in the pull bar top ring connected in star.
Good effect of the present utility model is:
When using the utility model, hold handle and following handle, by under pull on handle control pull bar and move down, the downward compression spring of pull bar, driving simultaneously with wedge shape sleeve center is that centrosymmetric fixture block moves down together with limit guide rail in the wedge shape sleeve, non-standard latch sample is inserted in the gap of three fixture blocks, unclamps handle and following handle, in the spring action lower link fast moving that makes progress, realized clamping to nonstandard latch sample.
