Abstract
The utility model discloses a displacement measuring and limiting device for a testing machine. The displacement measuring and limiting device comprises a base disposed under a workbench and a fixing support, wherein the fixing support is fixed on one side of the base via a screw. The displacement measuring and limiting device further comprises a pull-type photoelectric encoder and a limiting device. The pull-type photoelectric encoder is fixed on the fixing support via a base of the encoder; the lower surface of the workbench is provided with a hook; and a top end of a protruding portion of the pull-type photoelectric encoder is connected to the hook. The limiting device comprises a limiting rod, a limiting plate and a limiting switch; the upper end of the limiting rod is fixed below the workbench; the limiting plate is fixed on the limiting rod via a nut; and the limit switch is disposed on the fixing support and on one side, opposite to the limiting plate, of the fixing support. The displacement measuring and limiting device for the testing machine can measure displacement during a test, helps to ensure accuracy of displacement measurement and accuracy of the test, has a function of limiting control, and allows costs and space to be saved.
Description
Technical field
The utility model relates to a kind of displacement measurement and stop means, relates in particular to a kind of shift measurement and stop means for the test seat in the plane.
Background technology
At present, along with the development of society, the advancing by leaps and bounds of technology, displacement of testing machine is measured to rise to from initial tape measure already and is adopted photoelectric encoder to measure, and various displacement measuring devices and spacing measurement mechanism are connected on the testing machine to be used.The most general displacement measuring device is to adopt to be comprised of a plurality of assemblies such as base, riser, movable frame, hook, spring, rotating shaft, gear wheel, wire clamp, hook, block, worktable, because part is many, cause link complicated, the precision that impact is measured, this directly causes the accuracy of test findings, also brings very large puzzlement for the measuring and calculating of test findings; Spacing measurement mechanism independent design commonly used, connected mode is varied especially, and processing and installation are all more loaded down with trivial details.
Summary of the invention
Technical problem to be solved in the utility model is a kind of new test seat in the plane shift measurement and stop means quick and easy for installation of design.
For solving this technical matters, the utility model provides a kind of displacement of testing machine to measure and stop means, comprise the base and the fixed support that are positioned at the worktable below, fixed support is fixed by screws in a side of base, also comprise stay-supported photoelectric scrambler and stop means, the stay-supported photoelectric scrambler is fixed on the fixed support by the scrambler seat, is provided with hook at the lower surface of worktable, and the top of stay-supported photoelectric scrambler extension links to each other with hook; Described stop means comprises gag lever post, limiting plate and limit switch, the upper end of gag lever post be fixed on worktable below, limiting plate is fixed on the gag lever post by nut, limit switch is arranged on the fixed support, a side relative with limiting plate.
The lower end of described gag lever post is helicitic texture, and limiting plate requires to use hexagonal nut to be fixed on the lower end of gag lever post according to stroke.
Between described stay-supported photoelectric scrambler and the scrambler seat, all use screw attachment between scrambler seat and the fixed support.
Beneficial effect: the utility model can realize in process of the test guaranteeing preferably the displacement measurement precision to the measurement of displacement, guarantees the accuracy tested, can finish again the function of spacing control, saved cost and space.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Among the figure: 1 base, 2 fixed supports, 3 limiting plates, 4 gag lever posts, 5 scrambler seats, 6 stay-supported photoelectric scramblers, 7 hooks, 8 worktable, 9 limit switches.
Embodiment
The utility model adopts the stay-supported photoelectric scrambler to carry out displacement measurement.
Below in conjunction with drawings and Examples the utility model is done specific descriptions.
Figure 1 shows that structural representation of the present utility model.
The utility model provides a kind of displacement of testing machine to measure and stop means, comprise the base 1 and the fixed support 2 that are positioned at worktable 8 belows, fixed support 2 is fixed by screws in a side of base 1, also comprise stay-supported photoelectric scrambler 6 and stop means, stay-supported photoelectric scrambler 6 is fixed on the fixed support 2 by scrambler seat 5, lower surface at worktable 8 is provided with hook 7, and the top of stay-supported photoelectric scrambler 6 extensions links to each other with hook 7; Described stop means comprises gag lever post 4, limiting plate 3 and limit switch 9, the upper end of gag lever post 4 be fixed on worktable 8 below, limiting plate 3 is fixed on the gag lever post 4 by nut, limit switch 9 is arranged on the fixed support 2, a side relative with limiting plate 3.
The lower end of described gag lever post 4 is helicitic texture, and limiting plate 3 requires to use hexagonal nut to be fixed on the lower end of gag lever post 4 according to stroke.
Between described stay-supported photoelectric scrambler 6 and the scrambler seat 5, all use screw attachment between scrambler seat 5 and the fixed support 2.
Principle of work of the present utility model: during test, worktable 8 rises, and drives hook 7 and gag lever post 4 and moves up, the steel wire that hook 7 drives stay-supported photoelectric scrambler 6 moves, and feed back to control system, on the function software interface, show in real time and displacement realize the measurement to shift motion; When rising to predetermined ultimate range, limiting plate 3 contacts with limit switch 9, makes worktable stop to rise, thereby realizes spacing effect.
The utility model can realize in process of the test guaranteeing preferably the displacement measurement precision to the measurement of displacement, guarantees the accuracy tested, can finish again the function of spacing control, saved cost and space.
The above-mentioned embodiment of the utility model just illustrates, and is not only, all in the utility model scope or the change that is equal in the scope of the present utility model all surrounded by the utility model.
