On in the corresponding guide sleeve that is fixed with.
The relative wall of two locating pieces is molded fluted, and the both ends sleeve of axis to be processed in a groove and is pressed against recessed
On the end face of slot.
Elastic protection layer is fixed on the madial wall of the arc groove, elastic protection layer is pressed against the outside of axis to be processed
On wall.
The spring protective plate for being fixedly arranged in the middle of front and back extension for placing fixed plate, spring protective plate are in axis to be processed
Underface.
The beneficial effects of the utility model are:
It may be mounted on drilling machine, can automatically grip axis to be processed, drilling machine is facilitated to drill, and effect is good,
It is efficient.
Description of the drawings:
Fig. 1 is the partial top view of the utility model;
Fig. 2 is the partial structural diagram of the gripper cylinder and rack of the utility model.
Specific implementation mode:
Embodiment:See shown in Fig. 1 to Fig. 2, a kind of air-cylinder type automobile rocker axis processing clamping device, including rack 10, institute
The top surface for stating the top plate of rack 10 is fixedly arranged in the middle of placement fixed plate 11, and the front and rear for placing the both sides of fixed plate 11 is solid
Surely there is clamping cylinder 12, pushing block 13, the phase of corresponding two pushing blocks 13 in left and right are fixed on the push rod of clamping cylinder 12
To being fixed with grip block 14 on wall surface, the relative wall of two opposite grip blocks 14 has arc groove 141, axis to be processed
100 sleeves are in arc groove 141 and are clamped between corresponding four grip blocks 14;
The top surface front and rear of the top plate of the rack 10 is respectively and fixedly provided with vertical plate 16, two vertical plates 16 it is mutually separate
Wall surface on be respectively and fixedly provided with limit gripper cylinder 161, the push rod of limit gripper cylinder 161, which passes through, vertical plate 16 and is fixed with end
Limiting plate 163, is respectively and fixedly provided with locating piece 164 on the relative wall of two end limiting plates 163, and front and back the two of axis 100 to be processed
End face is pressed against on the end face of corresponding locating piece 164.
Further, the both sides of wall surface of the end limiting plate 163 against vertical plate 16 are respectively and fixedly provided with guide rod
165, in the corresponding guide sleeve 166 that 165 sleeve of guide rod is fixed on vertical plate 16.
Further, the relative wall of two locating pieces 164 is molded fluted, the both ends sleeve of axis 100 to be processed
In a groove and it is pressed against on the end face of groove.
Further, elastic protection layer 142, elastic protection layer 142 are fixed on the madial wall of the arc groove 141
It is pressed against on the lateral wall of axis 100 to be processed.
Further, the spring protective plate 1 for being fixedly arranged in the middle of front and back extension for placing fixed plate 11, spring protective
Plate 1 is in the underface of axis 100 to be processed.
The bottom surface of pushing block 13 is fixed with self-lubricating block, and self-lubricating block is pressed against on the top surface for placing fixed plate 11.
When in use, by the present embodiment be mounted on board on, by by axis 100 to be processed be clamped in four grip blocks 14 it
Between, then by two limit operations of gripper cylinders 161, the both ends sleeve of axis 100 to be processed in corresponding groove and is pressed against
On the end face of groove, realizes and fix, then can be processed, it is very convenient.
