The purpose of this utility model is to provide a kind of steel product stress relaxation testing machine that is easy to dismantle ground tackle, handled easily, to save overhead time, reduces labor intensity of operating personnel.
The purpose of this utility model realizes by following technical solution.
A kind of steel product stress relaxation testing machine, comprise frame, ground tackle, force cell, the load bar, intermediate support, end bearing and loading gear train, both ends bearing and the intermediate support coaxial cable that is parallel to each other is installed on the frame, the load bar is parallel to even layout of bearing axis and is bearing on the bearing, the outside of both ends bearing is separately installed with force cell and loads gear train, sample passes sensor, the end bearing, intermediate support and load sample mounting hole on the gear train leading screw, the ground tackle of being made up of the overcoat and the intermediate plate of wedge shape by its two ends is installed on the axial location of bearing.It also has by pull bar, top cover and ground tackle unloads the ground tackle body dumping mechanism that cover is formed, and ground tackle unloads cover and is fixed in the pull bar that loads on the gear train housing and ground tackle coaxial cable by even layout and is installed in outside the ground tackle, and the end face of ground tackle overcoat withstands on ground tackle and unloads and put; The top cover is sleeved on the sample between leading screw and the ground tackle for opening fraction, and an end contacts with leading screw, and the other end withstands on the little head end of anchor clipper.
It is that the hat ground tackle that an end offers the sample mounting hole unloads cover that ground tackle unloads cover.
Intermediate support top offers a groove that communicates with its sample mounting hole.
Below in conjunction with accompanying drawing embodiment of the present utility model is discussed in detail.
Fig. 1 is the structural representation of the utility model steel product stress relaxation testing machine.
Fig. 2 is the structural representation of ground tackle body dumping mechanism among Fig. 1.
Fig. 3 is the A-A cut-open view among Fig. 1.
The utility model steel product stress relaxation testing machine as shown in Figure 1, mainly is made up of frame 1, ground tackle 2, force cell 3, load bar 4, intermediate support 6, end bearing 7, loading gear train 8 and the white release mechanism of ground tackle.Both ends bearing 7 and intermediate support 6 coaxial cable that is parallel to each other is installed on the frame 1,4 load bars 4 are parallel to even layout of bearing 6,7 axis and are bearing on the bearing 6,7, the outside of both ends bearing 7 is separately installed with force cell 3 and loads gear train 8, sample 5 passes sensor 3, end bearing 7, intermediate support 6 and loads sample mounting hole on the leading screw 9 of gear train 8, be installed on the axial location of bearing 6,7 by the ground tackle of forming by wedge shape overcoat 2a and intermediate plate 2b 2 at its two ends, also the i.e. axial location of this testing machine.Intermediate support 6 tops offer a cannelure that communicates with its sample mounting hole, as shown in Figure 3, make sample 5 to be penetrated by the middle part of testing machine, save lab space to greatest extent.The ground tackle body dumping mechanism, see Fig. 2, mainly unload that cover 12 forms by pull bar 10, top cover 11 and ground tackle, it is that the hat that an end offers the sample mounting hole unloads cover that ground tackle unloads cover 12, be fixed in the pull bar 10 that loads on gear train 8 housings by even layout and be installed in ground tackle 2 outsides with ground tackle 2 coaxial cables, the end face of ground tackle 2 overcoat 2a withstands on ground tackle and unloads on the seam of cover 12; Top cover 11 is sleeved on the sample 5 between leading screw 9 and the ground tackle 2 for opening fraction, and an end contacts with leading screw 9, and the other end withstands on the little head end of ground tackle 2 intermediate plate 2b.
During work, start-up loading gear train 8, by motor-driven two-stage type cone envelope worm gear pair and lead screw transmission pair, the rectilinear motion by leading screw loads sample.After test is finished, ground tackle is unloaded cover 12 be installed to and be fixed on the pull bar 10 that loads on gear train 8 housings, oppositely start-up loading gear train 8 drives leading screws 9 and retreats, and makes to produce the top that is enough to pack between leading screw 9 and the ground tackle 2 and overlap 11 space.Then, start-up loading gear train 8 loads, and makes the end face of the overcoat 2a of ground tackle 2 withstand on ground tackle and unloads on the seam of cover 12, and top cover 11 1 ends contact with leading screw 9, and the other end withstands on the little head end of ground tackle 2 intermediate plate 2b.Continue to load, be connected as a single entity with loading gear train 8 because ground tackle unloads cover 12, so the overcoat 2a of ground tackle 2 is not removable, leading screw 9 moves with respect to its overcoat 2a through the intermediate plate 2b that top cover 11 promotes ground tackle 2, and ground tackle 2 is backed down, and finishes the dismounting of ground tackle 2.
The advantage that the utility model compared with prior art has is: be equipped with ground tackle certainly Release mechanism utilizes to load the dismounting of transmission mechanism realization ground tackle, is easy to dismounting, handled easily, Save overhead time, reduced operating personnel's labour intensity. Adopt the hat ground tackle Unload cover and make ground tackle add sheet can not go out in the moment of backing down, increased the security of producing. In addition Offer the groove that communicates with its sample installing hole on intermediate support top, so that the sample energy outward, Enough middle parts by testing machine penetrate, and save to greatest extent lab space, make simultaneously sample Installation more convenient.
