[ detailed description ] embodiments

In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention will be further described in detail with reference to the accompanying drawings and the following embodiments. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the invention.

It should be noted that all directional indications (such as up, down, left, right, front, and back … …) in the embodiments of the present invention are limited to relative positions on a given view, not absolute positions.

In addition, descriptions in the present application as to "first", "second", and the like are for descriptive purposes only and are not to be construed as indicating or implying relative importance or implicit to the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one such feature. In the description of the present invention, "a plurality" means at least two, e.g., two, three, etc., unless specifically limited otherwise.

Please refer to fig. 1 to 3, the utility model discloses a pneumatic clamping jig, including bearing bottom plate 10, the one side of bearing bottom plate 10 is fixed with a plurality of centre gripping cylinders 20, bearing bottom plate 10 another side is provided with a plurality of grip blocks 30, a plurality of grip blocks 30 positions respectively with a plurality of centre gripping cylinders 20 position one-to-one, the grip block 30 and the centre gripping cylinder 20 of mutual correspondence pass through screw 40 fixed connection, the relative bearing bottom plate 10 elevating movement of grip block 30 is driven to centre gripping cylinder 20. The clamping block 30 is used for clamping and fixing the cover plate products 50 on the supporting base plate 10. After the cover plate products 50 are fixed, drilling and tapping can be carried out.

Bearing bottom plate 10 is the rectangular plate, has seted up a plurality of through-holes 11 on the bearing bottom plate 10, a plurality of through-holes 11 are the matrix and arrange on bearing bottom plate 10, and grip cylinder 30's telescopic link 21 passes through-hole 11 and grip block 30 fixed connection, and through-hole 11 concertina movement can be followed to telescopic link 21.
