Oil cylinder rod head machining clamp with bottom supported in suspended mode

Abstract

The invention relates to the technical field of oil cylinder rod head clamps, and particularly relates to an oil cylinder rod head machining clamp with the bottom supported in a suspended mode. The clamp comprises a supporting plate, a penetrating hole is formed in the center of the supporting plate, lug plates are arranged at two sides of the supporting plate, rotating shafts are arranged at two sides of a connecting plate, the rotating shafts are rotatably connected to the lug plates, first motors are arranged outside the lug plates, the first motors are coaxially connected with the rotating shafts, guiding grooves are formed in annular blocks and are of a U-shaped structure, a bottom plate is arranged below the supporting plate, the guide grooves are formed in the upper portion of the bottom plate, the annular blocks are fixed to the guide grooves, a plurality of sliding rods are symmetrically arranged on the side surface of the supporting plate, and the sliding rods are connected into the guide grooves in a sliding mode. According to the clamp, overturning is completed through movement of the supporting plate along the guide grooves, the front surface a workpiece faces downwards, the backside of the workpiece faces upwards, a drill bit can machine the workpiece through a penetrating hole, a round hole and a machining hole, and the number of the end surfaces which can be machined through one-time clamping is increased to four.

Description

Technical field [0001] The present invention relates to a cylinder head clamp Field, in particular, to a bottom of the cylinder head of truss-supported processing jig. Background technique [0002] Cylinder head drilling process scheme, NC four-jaw chuck holding a workpiece, using a center positioned end surface to be fixed by bonding four four faces of the cylinder head, in the course of processing a surface of each of need to re-setup time, extremely troublesome, the conventional cylinder head includes a rotatable jig fixture, a fixture can be processed by a plurality of end faces of the cylinder head is rotated toward the surface control, but this approach does not support rollover Generally only process three sides except the sides of the fixing surface, requires additional setup operation once, when the bottom surface of the borehole is troublesome in this case, in view of this, the present invention proposes a floating bottom the cylinder head machining type support jig.

Problems solved by technology

[0003] The object of the present invention is to provide a jig for processing a cylinder rod head supported by a suspended bottom, to solve the problem that the existing cylinder rod head clamp proposed in the above-mentioned background technology includes a rotatable clamp, and the surface of the cylinder rod head can be adjusted by rotation. In this way, multiple end faces can be processed in one clamping, but this method does not support flipping. Generally speaking, only three faces can be processed except the fixed faces on both sides. In this case, additional drilling is required when drilling the bottom face. One-time clamping operation, more troublesome problem
