The utility model has the beneficial effects that: the upper clamping plate and the lower clamping plate are matched for use, the upper clamping plate and the lower clamping plate are tightly attached to a machining part of a part, and an inner hole is turned in the area through the clearance hole, so that the area near the inner hole is limited by a tool, the deformation degree is reduced, the error is reduced, and the finished product percent of pass of the part is improved.

Drawings

FIG. 1 is a side cross-sectional structural schematic view of the present invention;

fig. 2 is a schematic top view of the present invention.

In the figure: the device comprises a base 1, a first air cylinder 2, a rotating rod 3, a first lug plate 4, an upper clamping plate 5, a clearance hole 6, a cylinder body 7, a hose 8, a second air cylinder 9, a positioning pin 10, a lower clamping plate 11 and a second lug plate 12.

Detailed Description

In order to make the technical means, the original characteristics, the achieved purpose and the efficacy of the utility model easy to understand, the utility model is further described with reference to the specific drawings.

As shown in fig. 1-2, an automobile engine part tool comprises a base 1, a lower clamp plate 11 is fixedly connected to the base 1, an upper clamp plate 5 is arranged above the lower clamp plate 11, the upper clamping plate 5 and the lower clamping plate 11 are respectively provided with corresponding clearance holes 6, the two sides of the lower clamping plate 11 are respectively provided with a first cylinder 2 and a second cylinder 9, the first cylinder 2 and the second cylinder 9 are both fixedly connected with the base 1, the piston of the first cylinder 2 is fixedly connected with a rotating rod 3, the rotating rod 3 is hinged with the upper clamping plate 5, the piston of the second cylinder 9 is fixedly connected with a cylinder body 7, the two ends of the cylinder body 7 are both provided with bolts, and the bolts slide along the inner track of the cylinder body 7, the cylinder body 7 is sealed, the hose 8 is fixedly communicated with the cylinder body 7, the other end of the hose 8 is communicated with an air source, the hose 8 can move along with the lifting of the cylinder body 7, and provide pressure in the cylinder body 7, the cylinder body 7 realizes the removable connection with lower splint 11 through the receipts and releases of bolt.

The equal first otic placode 4 of fixedly connected with in one side both ends of punch holder 5, two first otic placodes 4 all rotate with bull stick 3 and cup joint, just so make the stress point dispersion of punch holder 5 on both sides, guarantee that the atress when punch holder 5 pushes down is balanced.

Two second otic placodes 12 of one side fixedly connected with that first cylinder 2 was kept away from to punch holder 5, and cylinder body 7 is located between two second otic placodes 12, and the connection setting of double bolts makes second cylinder 9 bigger with punch holder 5's joint strength, and the centre gripping is more fastened.

The locating pin 10 is fixedly connected to the four corners of the top of the lower clamp plate 11, and the locating holes are formed in the four corners of the upper clamp plate 5, so that the lower clamp plate 11 and the upper clamp plate 5 are more stable when being clamped, and cannot deviate due to stress.

One side that lower plate 11 and upper plate 5 are close to each other sets up to the binding face with part assorted, further improves the centre gripping stability to the part.
