Abstract
The utility model discloses a bar clamping device which comprises a clamp sleeve, a connecting base, an oil cylinder and a hollow piston rod, wherein the clamp sleeve and the oil cylinder are fixed at the two ends of the connecting base respectively, a clamping head is arranged inside the clamp sleeve and is fixed at one end of the hollow piston rod, a cone ring is arranged inside the front end of the clamp sleeve, a composite sleeve is arranged inside the rear end of the clamp sleeve, a rear support ejecting head is arranged inside the composite sleeve and is fixed on the connecting base, a piston rod retreating adjusting ring is arranged at one end, inside the connecting base, of the hollow piston rod, a locking nut is arranged at the front end of the piston rod retreating adjusting ring, and the connecting base is fixed on a connecting base baseboard. The bar clamping device is capable of clamping or loosening a bar automatically in a bar machining process and effectively relieving labor intensity, high in efficiency, and capable of being matched with other devices.
Description
Technical field
The utility model relates to the bar processing technique field, says so exactly to relate to a kind of bar clamping device.
Background technology
Bar processing is a kind of common machining.At present, the processing bar is by manually finishing charging, material folding, discharging.The intensity of hand labor is big, inefficiency, and in process bar crudy instability.
The utility model content
The technical problems to be solved in the utility model provides a kind of minimizing hand labor intensity, efficient height, the bar clamping device that energy and other matched with devices are used.
For solving the problems of the technologies described above, bar clamping device of the present utility model comprises anchor clamps cover, Connection Block, oil cylinder, the hollow piston bar, it is characterized in that: anchor clamps cover, oil cylinder are separately fixed at the Connection Block two ends, are provided with chuck in the anchor clamps cover, and chuck is fixed on an end of hollow piston bar, anchor clamps cover front end inside is provided with conical ring, anchor clamps cover inside, rear end is provided with compound cover, is provided with the back brace top in the compound cover, and the back brace top is fixed on the Connection Block.
As to further improvement of the utility model, bar clamping device of the present utility model, the hollow piston bar end in Connection Block is provided with piston rod and retreats adjustable ring, and piston rod retreats the adjustable ring front end and is provided with lock nut.
As to further improvement of the utility model, bar clamping device of the present utility model, Connection Block is fixed on the Connection Block base plate.
When bar clamping device workpiece of the present utility model is pushed in the chuck, cylinder action, the hollow piston bar moves to left, and the chuck that is fixed on hollow piston bar one end puts in conical ring, under the effect of conical ring, chuck awl end parts workpiece pressing.When the hollow piston bar moves to right, the drive chuck moves to right, when chuck is run into back brace top end, the bare terminal end expansion of chuck, workpiece is released, back brace top is placed in can effectively avoid chuck because of the elastic failure pine part that do not go into operation in the chuck, allows the bigger of chuck expansion, can hold slightly bigger caliber part and also can pass through chuck smoothly.Bar clamping device of the present utility model can be realized the clamping in the bar process automatically and unclamp, and can effectively reduce hand labor intensity, the efficient height, and can use with other matched with devices.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is cutaway view of the present utility model.
Description of reference numerals:
The 1-conical ring; 2-anchor clamps cover; The 3-chuck; 4-back brace top; The 6-piston rod retreats adjustable ring; The 7-Connection Block; The 8-oil cylinder; 9-hollow piston bar; 10-Connection Block base plate; The compound cover of 11-.
The specific embodiment
Engaging accompanying drawing below is described in further detail the utility model.In conjunction with Fig. 1, Fig. 2 as can be known, oil cylinder 8, anchor clamps cover 2 is separately fixed at Connection Block 7 two ends, chuck 3 is fixed on an end of the hollow piston bar 9 in the oil cylinder 8, hollow piston bar 9 is provided with piston rod and retreats adjustable ring 6; Conical ring 1, compound cover 11 close-fittings overlap 2 endoporus two ends at anchor clamps, and the back brace top 4 in the chuck 3 is fixed on Connection Block 7 one ends, and Connection Block 7 is fixed on the Connection Block base plate 10.
The clamping of bar workpiece: workpiece is pushed in the chuck 3, oil cylinder 8 actions, and hollow piston bar 9 moves to left, the chuck 3 that is fixed on hollow piston bar 9 one ends puts in conical ring 1, under the effect on conical ring 1 inclined-plane, chuck 3 is bored the end parts workpiece pressings, thereby can realize the clamping to the bar workpiece.
Unclamping of bar workpiece: when hollow piston bar 9 moves to right, driving chuck 3 moves to right, when skew wall in the chuck 3 is run into back brace and is come directly towards 4 beveled end, the bare terminal end expansion of chuck 3, workpiece is released, back brace top 4 the effects in the chuck 3 of being placed in are to avoid chuck 3 because of the elastic failure pine part that do not go into operation, and allow the bigger of chuck 3 expansions, can hold slightly bigger caliber part and also can pass through chuck 3 smoothly.
