Description

A kind of air-actuated jaw

Technical field

The utility model relates to a kind of anchor clamps, specifically is the air-actuated jaw that can automatic capturing in a kind of workpiece pressing process compresses a little.

Background technology

In actual production in enormous quantities, when on upright drill, workpiece being carried out the aperture chamfering, for than small workpiece, generally be directly to hold steadily directly to move to after holding level with both hands to carry out the aperture chamfering under the drill bit with hand, but for workpiece heavier, in irregular shape, do following two kinds of drawbacks like this: 1, operative employee's labour intensity is big; 2, because of wayward than heavy industry spare, the aperture chamfering is easily inclined to one side, dark, the more shallow situation of one side chamfering of chamfering on one side promptly occurs, and the chamfering deflection can influence the uniformity and the aesthetics of workpiece.The chamfering clamp that the thinking that compresses according to the plane and two pits of routine location, pressing plate is designed, clamping that workpiece is auxiliary and take-down time are greater than effective process time of chamfering, though guaranteed the uniformity of workpiece, but operative employee's labour intensity does not reduce, and for producing in enormous quantities, production efficiency is low excessively.

Summary of the invention

The purpose of this utility model be to overcome the deficiency that prior art exists and provide a kind of to each aperture on the heavier and irregular workpiece planarization carry out chamfering, simple and efficient to handle, can guarantee workpiece chamfer quality and the high air-actuated jaw of efficient.

The technical solution of the utility model is: riser is fixed on base one side, and top positioning plate is fixed in the riser top, and cylinder and base are fastenedly connected, and the lifting push rod that is oppositely arranged with top positioning plate is housed on the cylinder; Hole is arranged on the top positioning plate, and described hole is corresponding with the hole on the product that need carry out chamfer machining.

Described lifting push rod top is the jacking block that is provided with according to workpiece profile and selected clamped position, and the bottom is the screw rod that links to each other with cylinder.

Described jacking block is an elongated cylinder, and jacking block and screw rod are T-shape.

Described jacking block is spherical.

Described riser medial surface is fixed with the side limiting plate.

Described cylinder is connected with manual Push-and-pull valve through sebific duct, and manually Push-and-pull valve is fixed in the riser back side through fixture.

The utility model can carry out chamfering to each aperture on the heavier and irregular workpiece planarization, compressed air with cleaning is the power resources of clamping force, can automatic capturing in the workpiece pressing process compress point, simple and efficient to handle, can guarantee workpiece chamfer quality and efficient height.The utility model is simple in structure, and is easy and simple to handle, be applied to actual production after, reduced operative employee's labour intensity, improved production efficiency, promoted the automatization level of production line.

Description of drawings

Fig. 1 is a structural representation of the present utility model.

Fig. 2 is the vertical view of Fig. 1.

Fig. 3 is the structural representation of lifting push rod among Fig. 1.

Among the figure, 1, base, 2, riser, 3, the manual fixture of Push-and-pull valve, 4, manual Push-and-pull valve, 5, the side limiting plate, 6, the boss on the workpiece, 7, the lifting push rod, 8, cylinder, 9, φ 8 sebific ducts, 10, need the plane of aperture chamfering on the workpiece, 11, top positioning plate, 12, the pressurized air lines on the production line, 13, jacking block, 14, screw rod.

The specific embodiment

Among Fig. 1, Fig. 2, clamp body is made up of the fixture 3 of base 1, riser 2, top positioning plate 11, side limiting plate 5, lifting push rod 7, cylinder 8, manual Push-and-pull valve 4, φ 8 sebific ducts 9, manual Push-and-pull valve, wherein riser 2 is fixed on base 1 one sides, top positioning plate 11, side limiting plate 5 are separately fixed at riser 2 tops and riser 2 medial surfaces, cylinder 8 is by being bolted to the appropriate location of base 1, and lifting push rod 7 links to each other by the piston rod of screw thread with cylinder 8.Manually Push-and-pull valve 4 is fixed on the appropriate location at riser 2 back sides by fixture, and manually Push-and-pull valve 4 is connected with pressurized air lines 12 on the production line with cylinder 8 respectively through φ 8 sebific ducts 9.Be milled with hole everywhere in the middle of the top positioning plate 11, in order to expose each aperture on the plane that to carry out chamfer machining.6 is the boss on the workpiece, and 10 is the plane that needs the aperture chamfering on the workpiece.Cylinder 8 is the slim cylinder of standard, and its axial dimension is little, and compact conformation is easy to install, can realize the automatic control of cylinder.The piston rod surface chromium plating of cylinder 8, corrosion-resistant, wear-resistant.The piston rod of cylinder 8 can stretch and rotate along axis vertically.

Among Fig. 3, the jacking block 13 on lifting push rod top is an elongated cylinder, and the bottom is the screw rod 14 that links to each other with cylinder piston rod, and jacking block 13 and screw rod 14 form T-shape by welding.Different workpiece profiles and selected clamped position have determined the difformity of push rod, as

Type etc.The lifting push rod links to each other with cylinder piston rod by screw thread, aligns previously selected compressing a little on the workpiece automatically by the flexible of lifting push rod, until workpiece is clamped between lifting push rod and the top positioning plate.

The utility model since make full use of cylinder 8 piston rods to Telescopic and along the spinfunction of axis, and effectively utilize the boss bottom conduct on the workpiece profile to compress a little, need carry out the plane of aperture chamfering as locating surface, when so the lifting push rod 7 that links to each other with cylinder 8 moves upward, because the spinfunction of cylinder piston rod, jacking block 13 (elongated cylinder) on the lifting push rod 7 with process that the workpiece profile contacts in can rotate automatically to avoid workpiece with the workpiece profile, just horizontal in the boss bottom, and the jack-up whole work-piece continues to move upward, top positioning plate 11 on plane 10 that needs the aperture chamfering on the workpiece and clamp body develops and clamps, and this moment, workpiece was clamped between the lifting push rod 7 and top positioning plate 11 that is connected with cylinder 8.Because need carry out the plane of aperture chamfering always develops with the top positioning plate that is in level, so improved the crudy of chamfering, simultaneously because the utility model does not adopt conventional plane and two pits location, the thinking design that pressing plate compresses, so greatly reduce the making precision of anchor clamps.

Concrete operations step: 1. will need a side on the plane 10 of aperture chamfering to align on the workpiece with side limiting plate 5; 2. the manual Push-and-pull valve 4 of push-and-pull, lifting push rod 7 moves upward, and aligns and withstand on the bottom of the boss 6 on the workpiece automatically, needs the plane 10 of aperture chamfering to develop and clamp with top positioning plate 11 on workpiece; 3. the aperture chamfering is carried out in each aperture on the plane 10 that needs the aperture chamfering on the workpiece; 4. the manual Push-and-pull valve 4 of push-and-pull round about, lifting push rod 7 unclamps workpiece when moving downward.
