Description
Technical field
This utility model relates to clamp art, particularly to a kind of perforation shell case projection detection fixture.
Background technology
Perforating oil gas well is a key technology in petroleum exploration & development, and the effect of perforating bullet is shot through down-hole envelope exactly
Close the sleeve pipe of target zone, cement sheath and go deep into target zone, forming effective seepage channel of target zone and pit shaft, it is ensured that Oil/gas Well obtains
Obtain due production capacity.Perforation shell case needs to measure overall dimensions after machining.Measure the conventional of workpiece configurations size at present
Means are made by vision inspection apparatus.Specifically, first perforating bullet shell workpiece is placed on vee-block, then recycles projection
Overall dimensions quickly measured by instrument.This metering system is owing to being to be directly placed on vee-block by perforation shell case, during measuring
Usually there will be following defect: first, position degree when workpiece is put is difficult to hold so that had a strong impact on the standard of measurement result
Exactness；Second, the workpiece of various outer diameter size needs to be respectively configured corresponding vee-block, causes versatility poor；3rd, due to
Perforation shell case is hollow structure, and when perforating bullet shell workpiece is placed on above-mentioned vee-block, CCD camera cannot be relative to the end of workpiece
Center, face carries out fixed length focusing, causes can not accurately carrying out dimensional measurement because projection is more fuzzy.
Utility model content
The purpose of this utility model is the defect for prior art and deficiency, it is provided that a kind of perforation shell case projection detection
Fixture, it is simple and reasonable, easy to use, and versatility is relatively strong, and workpiece mounting position degree is higher, it is possible to measurement essence is effectively ensured
Degree.
For achieving the above object, this utility model is by the following technical solutions:
A kind of perforation shell case projection detection fixture described in the utility model, including fixture location-plate, described fixture positions
The front end face of plate is smooth flat, and the front end face of described fixture location-plate is provided with a pair for the support placing workpiece for measurement
Lever, the rear end face of described fixture location-plate is fixedly connected with magnetic support switching device.
Further, two described support levers are contour setting.
Further, described support lever is threadeded with described fixture location-plate.
Further, described support lever includes becoming with described large-diameter portion one for the large-diameter portion placing workpiece for measurement
The minor diameter part that type is arranged, described large-diameter portion is connected with described fixture location-plate by described minor diameter part.
The beneficial effects of the utility model are: the perforation shell case projection detection fixture that this utility model provides, by folder
A pair support lever is set on the front end face of tool location-plate, and in the rear end face installation magnetic support switching device of fixture location-plate, peace
During dress, this utility model is integrally placed on the glass of projector, during use, first unclamps magnetic support switching device, by workpiece for measurement
Positioned axially on two support levers, make the big planar ends of workpiece for measurement be adjacent to fixture location-plate, be then shut off magnetic support and open
Closing device, workpiece for measurement is adsorbed on fixture location-plate by the magnetic attraction produced by magnetic support switching device, the most just completes
Clamping to workpiece for measurement.After clamping completes, just can utilize projector that the overall dimensions of product to be measured is measured.
In sum, compared with prior art, this utility model due to be workpiece for measurement is placed on two support levers
On, and use the mode of magnetic attracting to fix workpiece for measurement, not only versatility is stronger, it is possible to be applied to the work of various outer diameter size
Part, and also advantageously improve the position degree of workpiece for measurement, additionally, due to the big planar ends of workpiece for measurement is and fixture location-plate
Being pulled together, when carrying out dimensional measurement, fixture location-plate can play the effect of reference plane very well so that projector energy
Enough accurately focusings, thus ensure that accuracy of measurement of the present utility model.This utility model structure arranges advantages of simple, user
Just.

Detailed description of the invention
Below in conjunction with the accompanying drawings this utility model is further described.
A kind of perforation shell case projection detection fixture as shown in Figure 1 to Figure 3, including fixture location-plate 1, fixture location-plate 1
Front end face is smooth flat, uses smooth flat can improve fixture location-plate 1 and workpiece for measurement 2 degree of laminating, thus is conducive to
Ensure certainty of measurement.The front end face of fixture location-plate 1 be provided with a pair for the support lever 3 placing workpiece for measurement 2, in order to fill
Formula just, supports lever 3 and threadeds with fixture location-plate 1, specifically, supports lever 3 and includes for placing workpiece for measurement 2
Large-diameter portion 31 and the minor diameter part 32 of the one-body molded setting of large-diameter portion 31, large-diameter portion 31 is by minor diameter part 32 and fixture location-plate 1
It is connected.In order to ensure that the support effect to workpiece for measurement 2 is more preferable, two support lever 3 in contour setting.Fixture location-plate
The rear end face of 1 is fixedly connected with magnetic support switching device 4.
During installation, this utility model is integrally placed on the glass of projector, during use, first unclamps magnetic support switching device
4, support positioned axially for workpiece for measurement 2 on lever 3 at two, make the big planar ends of workpiece for measurement 2 be adjacent to fixture location-plate
1, it is then shut off magnetic support switching device 4, it is fixed that workpiece for measurement 2 is adsorbed at fixture by the magnetic attraction produced by magnetic support switching device 4
On the plate 1 of position, the most just complete the clamping to workpiece for measurement 2.After clamping completes, projector just can be utilized product to be measured
Overall dimensions measures.
Compared with prior art, this utility model is owing to being workpiece for measurement 2 to be placed on two support on levers 3, and adopts
Fixing workpiece for measurement 2 by the mode of magnetic attracting, not only versatility is stronger, it is possible to be applied to the workpiece of various outer diameter size, and
And also advantageously improve the position degree of workpiece for measurement 2, additionally, due to the big planar ends of workpiece for measurement 2 is to inhale with fixture location-plate 1
Being combined, when carrying out dimensional measurement, fixture location-plate 1 can play the effect of reference plane very well so that projector energy
Enough accurately focusings, thus ensure that accuracy of measurement of the present utility model.
The above is only better embodiment of the present utility model, therefore all according to described in this utility model patent claim
