Abstract
The invention discloses a tester displacement measuring and limit device. The device comprises a pedestal, a fixing bracket, a guyed photoelectric encoder and a limit device, wherein the pedestal and the fixing bracket are positioned below a workbench; the fixing bracket is fixedly arranged on one side of the pedestal through a screw; the guyed photoelectric encoder is fixedly arranged on the fixing bracket through an encoder base; a hook is arranged on the lower surface of the workbench; the top end of an extending part of the guyed photoelectric encoder is connected with the hook; the limit device comprises a limit rod, a limit plate and a limit switch; the upper end of the limit rod is fixedly arranged on the lower surface of the workbench; the limit plate is fixedly arranged on the limit rod through a nut; and the limit switch is arranged on the side, opposite to the limit plate, of the fixing bracket. By the device, displacement can be measured in a testing process, the displacement measuring precision can be better ensured, the accuracy of test is ensured, a limit control function can also be finished, and the cost and the space are saved.
Description
Technical field
The present invention relates to a kind of displacement measurement and stop means, relate 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, the testing machine displacement measurement rises to from initial tape measure already and adopts 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 made up of a plurality of assemblies such as base, riser, mobile framework, hook, spring, rotating shaft, gear wheel, wire clamp, hook, block, worktable, because part is many, cause the link complexity, the precision that influence is measured, this directly causes accuracy of experimental results, also brings very big 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 matters to be solved by this invention is a kind of novel testing machine displacement measurement and stop means quick and easy for installation of design.
For solving this technical matters, the invention provides a kind of testing machine displacement measurement and stop means, comprise the base and the fixed support that are positioned at the worktable below, fixed support is fixed on a side of base by screw, 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: present invention can be implemented in the process of the test the measurement of displacement, can guarantee the displacement measurement precision preferably, guarantee the accuracy tested, can finish the function of spacing control again, saved cost and space.
Description of drawings
Fig. 1 is structural representation of the present invention.
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 present invention adopts the stay-supported photoelectric scrambler to carry out displacement measurement.
Below in conjunction with drawings and Examples the present invention is done specific descriptions.
Figure 1 shows that structural representation of the present invention.
The invention provides a kind of testing machine displacement measurement and stop means, comprise the base 1 and the fixed support 2 that are positioned at worktable 8 belows, fixed support 2 is fixed on a side of base 1 by screw, 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 invention: 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.
Present invention can be implemented in the process of the test the measurement of displacement, can guarantee the displacement measurement precision preferably, guarantee the accuracy tested, can finish the function of spacing control again, saved cost and space.
The above-mentioned embodiment of the present invention just illustrates, and is not only, all within the scope of the present invention or the change that is equal in the scope of the present invention all surrounded by the present invention.
