Thin wall cover locating clamping device of the present invention, the structure of wherein said pressure arm pushing mechanism is: be fixed with the oil cylinder 25 that joins with fluid pressure drive device on support 28, be connected for axle between the termination of the piston rod that matches with oil cylinder 25 and the left end head of described pressure arm 15.

Thin wall cover locating clamping device of the present invention, the structure of wherein said movable block pushing mechanism is: be provided with the inclined-plane and move block 6 between inclined-plane movable block 7 and support 28, passing the pilot hole 5 that moves on the block 6 on the inclined-plane with guide post 9 that inclined-plane movable block 7 matches fixedlys connected with support 28, the inclined-plane moves block 6 and is threaded with adjusting bolt 29, adjusts support member 30 axial location of bolt 29 by fixedlying connected with support 28.

Thin wall cover locating clamping device of the present invention, the structure of the axial push-pull mechanism of the wherein said axis of cone is: axle is connected with swing arm 24 on support 28, the bottom of swing arm 24 is connected with an end hinge of impeller-hub 1 on being supported on support 28, impeller-hub 1 is threaded with push-and-pull nut 3 on being fixed on support 28, the other end of push-pull shaft 1 is provided with twisting termination 4, the upper end of swing arm 24 is connected with bolt shaft 20 hinges, and bolt shaft 20 is joined with the axis of cone 12.

Thin wall cover locating clamping device of the present invention, because the outside at part clamps, simultaneously expansion mechanism is arranged in the inboard of part, the clamping force in the outside is cancelled out each other with inboard expansive force during clamping, makes part not be subjected to bigger chucking power, and is not yielding, and guaranteed the steadiness that part clamps, improved machining accuracy, time saving and energy saving, overcome the high shortcoming of thin-walled parts processing cost.

Description of drawings

Fig. 1 is the structural representation of the specific embodiment of the invention.

The specific embodiment

As shown in the figure: 28 is support, can adopt casting.The oil cylinder 25 that joins with fluid pressure drive device is bolted on the support 28, the external end head of the piston rod 23 that matches with oil cylinder 25 is connected with the left end head hinge of pressure arm 15 by axle 21, middle part at pressure arm 15 is supported on pressure arm 15 on the support plate 16 by axle 18, support plate 16 is fixedlyed connected with support 28, and support plate 16 can be structure as a whole with support 28 or welding or bolting are connected.Right-hand member head at pressure arm 15 is fixedly connected with upper grip 10, is connected for screw between upper grip 10 and the pressure arm 15 or is processed into integrative-structure.

The inclined-plane that support 28 is provided with tape guide hole 5 moves block 6, has been located inclined-plane movable block 7 on the inclined-plane above the inclined-plane moves block 6, and the right end of inclined-plane movable block 7 is fixedly connected with lower chuck 8.Fixedly connected with support 28 with the pilot hole 5 that the inclined-plane moves on the block 6 in the hole that guide post 9 passes on the inclined-plane movable block 7.The inclined-plane moves block 6 and is threaded with adjusting bolt 29, and support member 30 is fixedlyed connected with support 28, adjusts to be processed with pillow block on the bolt 29 and to pass through support member 30 with respect to support 28 axial location.

Be supported with push-pull shaft 1 by axle sleeve 2 on support 28, bolting is connected between push-and-pull nut 3 and the support 28, is processed with external screw thread on the push-pull shaft 1 and is threaded with push-and-pull nut 3, and the right-hand member head of push-pull shaft 1 is processed with the four directions as twisting termination 4.The left end head of push-pull shaft 1 is connected with a bottom hinge of swing arm 24, and the middle part of swing arm 24 is connected with 27 of pedestals by axle 26, and pedestal 27 is fixedlyed connected with support 28.The upper end of swing arm 24 is connected with bolt shaft 20 hinges, and bolt shaft 20 is threaded with the axis of cone 12.The axis of cone 12 is supported on the support 28 by axis of cone cover 19, cover 17, is set with expansion sleeve 11 in the outside of the axis of cone 12, and by trim ring 13 expansion sleeve 11 is bolted on the support 28, axially is processed with opening on the expansion sleeve 11.The height and position of expansion sleeve 11 is between upper grip 10 and the lower chuck 8.
