Description

A kind of general clamping jig of vision-based detection

Technical field

It the utility model is related to vision-based detection tool field, more particularly to a kind of general clamping jig of vision-based detection.

Background technology

Product supplied materials vision-based detection generally comprises height detection, profile measurement etc..In existing technology, product supplied materials vision Detection is detected by manually carrying out blowing, and can only once put a material, and efficiency is low, and labor intensity is big.It is in addition, existing Some vision-based detection tools are when being overturn or being moved to product supplied materials after the completion of an appearance test, it is necessary to fill again Folder, causes secondary position error, causes measurement accuracy to reduce.

In summary, the existing vision-based detection clamping jig, in practice in the presence of it is inconvenient the problem of, it is therefore necessary to add To improve.

Utility model content

The purpose of this utility model is to provide a kind of general clamping jig of vision-based detection, can once measure justifying production simultaneously Product supplied materials, and various shapes detection can be carried out in the tool, avoid product supplied materials when needing to overturn or being mobile, again clamping Produce measurement error.

To achieve the above object, using following technical scheme：

A kind of general clamping jig of vision-based detection, including clamp base, limited post, fixture, fixture pass through limited post clamping Above clamp base；The fixture includes stacking fixture bottom sheet, fixture upper piece, the fixture cover of connection from the bottom up successively Plate.

It is preferred that the fixture cover plate bottom is surrounded by some spacer pins, the spacer pin is centered around fixture bottom sheet With fixture upper piece surrounding.

It is preferred that the clamp base includes clamp bottom board, some square magnets, circular magnet；The circular magnet is lived It is dynamic to be connected to clamp base center；The clamp bottom board length direction two edges are provided with straight-line groove, some square magnet fillings In the straight-line groove.

It is preferred that the square magnet is filled in the middle part of straight-line groove length direction, and both sides square magnet is symmetrical arranged.

Using such scheme, the beneficial effects of the utility model are：

1) a justifying product supplied materials, i.e. product supplied materials group, efficiency high can be once measured simultaneously；

2) when product supplied materials group needs to overturn or be mobile, it is not necessary to clamping repeatedly, improve measurement accuracy；

3) clamping jig can be run on automechanism, realized detection automation, reduced cost of labor.

Embodiment

Below in conjunction with the drawings and specific embodiments, the utility model is described in detail.

As shown in Figures 1 and 2, the general clamping jig of a kind of vision-based detection, including clamp base 2, limited post 3, fixture 1, Fixture 1 is connected to the top of clamp base 2 by limited post 3；Under fixture of the fixture 1 including stacking connection from the bottom up successively Piece 11, fixture upper piece 12, fixture cover plate 13.

Wherein, the bottom of fixture cover plate 13 is surrounded by some spacer pins 5, and the spacer pin 5 is centered around under fixture Piece 11 and the surrounding of fixture upper piece 12.The clamp base 2 includes clamp bottom board 23, some square magnets 21, circular magnet 22；Institute State circular magnet 22 and be movably connected on the center of clamp base 2；The length direction two edges of clamp bottom board 23 are provided with straight-line groove, Some square magnets 21 are filled in the straight-line groove.The square magnet 21 is filled in the middle part of straight-line groove length direction, and Both sides square magnet 21 is symmetrical arranged.The fixture cover plate 13 and clamp bottom board 23 pass through square magnet 21, circular magnet 22 Realize that magnetic connects.

As shown in Figure 1 to Figure 3, in the present embodiment, when being detected to product supplied materials group 4, product supplied materials group 4 is put into Between fixture bottom sheet 11 and fixture upper piece 12, with to the shaping of product supplied materials group 4；Fixture cover plate 13 is covered, to fix product Material group 4, and 4 position in fixture 1 of product supplied materials group is accurately positioned by spacer pin 5.Fixture 1 is erected at by limited post 3 The top of clamp base 2, limited post 3 realize fixture 1 in clamp base 2 without rock, off normal phenomenon.Fixture cover plate 13 uses magnetic Iron phase inhales device, realizes that product supplied materials group 4 clamps by square magnet 21, the device is also easy to dismount.Circular magnet 22 is located at The center of clamp base 2, balance dynamics is played, prevents the effect of fixture 1 and the unbalance stress of product supplied materials group 4.

The step of fixture 1 for fixing product supplied materials group 4 is put into automatic equipment detection is as follows：

1) fixture 1 for fixing product supplied materials group 4 is put into the clamp base 2 of detection height station, laser displacement passes Sensor module 9 starts detection height, and fixture 1 and product supplied materials group 4 are taken out after completing height detection；

2) fixture 1 for fixing product supplied materials group 4 is overturn 180 °, is then placed in the clamp base 2 of detection profile station In, camera module 8 starts to detect the profile of product supplied materials group 4；

3) stationary fixture 1 of taking-up product supplied materials group 4 after detecting is completed, then takes out product supplied materials group 4, action is completed.

This clamping jig 6 coordinates the nonstandard special camera module 8 of high-speed, high precision and laser displacement sensor module 9 to measure number According to reach the characteristics of fast precision high stability of speed is good.A justifying product supplied materials, efficiency high can be once measured simultaneously；And press from both sides Positioning datum is constant after 180 ° of the upset of tool 1, reduces double measurement clamping error, improves measurement accuracy；Mechanism automatic running, worker Only need a people to nurse multiple devices automatic production simultaneously, greatly reduce cost of labor, reduce labor strength.

Preferred embodiment of the present utility model is these are only, is not limited to the utility model, it is all in this practicality All any modification, equivalent and improvement made within new spirit and principle etc., should be included in guarantor of the present utility model Within the scope of shield.
