arms

70a and 70b are separated to release the clamping state;

when the electronic cigarette case 10 needs to be clamped, the electronic cigarette case 10 is firstly placed into the clamping groove 73 between the pair of clamping

arms

70a and 70b (when the pair of clamping

arms

70a and 70b are in a separated state, only a gap exists between the clamping arms, and the placement of the electronic cigarette case 10 is not affected); then, the cylinder 30 is activated to make the pneumatic shaft 31 push the moving arm 50 forward, so that the moving arm 50 pushes the first end 61 of the first connecting rod 61 to move forward, at this time, an included angle between the second connecting rod 62 and the third connecting rod 63 needs to be increased, the second end 622 of the second connecting rod 62 is fixed, the second end 632 of the third connecting rod 63 drives the sleeved arm 71 to move towards the side away from the second end 622 of the second connecting rod 62, and finally, the pair of clamping

arms

70a,70b are attached to each other to clamp the electronic cigarette housing 10.

The application discloses add clamping apparatus, but wide application in technologies such as CNC processing, welding, laser, highlight chamfer, burnishing and polishing. And is not limited to the machining of the e-cigarette housing.

The utility model provides a add clamping apparatus uses the central line in a pair of

centre gripping arm

70a,70 b's centre gripping groove 73 all the time as the processing benchmark, when the centre gripping, is through a pair of centre gripping arm 70a, the even relative motion centre gripping of 70b, and two the assembly central line position in centre gripping groove 73 is unchangeable, add man-hour direct with centre gripping groove 73 central line as the processing benchmark can, need not to divide again and look for the processing benchmark, practiced thrift process time greatly, promoted efficiency.

This application electron cigarette casing is with add clamping apparatus through set up the centre gripping groove 73 of mutually supporting on the opposite face of a pair of

centre gripping arm

70a,70b, and the relative concerted movement of rethread a pair of

centre gripping arm

70a,70b comes the centre gripping product, and central point between a pair of centre gripping groove 73 puts invariable all the time, can directly regard as processing reference axis, need not to divide again and seeks, has promoted efficiency greatly.
