Background

In machining, the boring machine is a machine tool for boring and machining the existing prefabricated holes of workpieces by using a boring cutter, is widely applied and can be used for machining high-precision holes or finishing a plurality of holes at one time in a positioning mode. The rotary motion of the boring cutter is the main motion during processing, and the movement of the boring cutter is the feeding operation. The boring cutter is generally mounted on a boring bar, the boring cutter and the boring bar are mounted on a main shaft and rotate along with the main shaft, and the forward and backward movement of the main shaft drives the boring cutter to perform feeding movement.

The feeding motion of the boring machine during boring processing has a certain range, the general processing range is equal to the extension limit size of the spindle plus the length of the external boring bar, and the length of the external boring bar of the boring machine is generally not more than 400 mm. If the external boring bar is too long, the boring machine can bear the torque generated when the boring bar rotates and also bear the flexible torque generated when the boring bar bends downwards, and the boring bar can shake the boring machine and cannot move the boring bar when boring is carried out. However, when the boring machine is used for boring, a deep hole and a coaxial hole with a large span are often touched, the shaft hole often exceeds the processing limit of the boring machine, if the processing effect is not ideal, the vibration of the boring rod can cause unqualified roughness of the processed hole and easy breakage of a blade, the boring machine cannot process a workpiece with the boring rod and even can damage the boring machine, and if machine tool equipment is replaced, the processing cost is inevitably increased rapidly.

In order to solve the problem, the utility model provides a floating support for boring machine to the problem of unable processing when solving the great coaxial hole of boring machine processing deep hole and span.

In order to solve the technical problem existing in the prior art, the utility model provides a floating support for boring machine.

Therefore, the utility model discloses a floating support for boring machine comprises extension boring bar, fixed bolster, foundatin plate, last ball tile, lower ball tile, self-aligning bearing, bearing. Wherein: the self-aligning bearing is fixed between the upper ball tile and the lower ball tile; the lower ball tile is provided with a T-shaped boss, the supporting seat is provided with a T-shaped groove, the upper ball tile, the lower ball tile and the self-aligning bearing are matched and positioned, the upper ball tile, the lower ball tile and the self-aligning bearing are arranged on the supporting seat by a T-shaped bolt, and the lower ball tile and the supporting seat can move left and right relatively through the T-shaped groove; the supporting seat is fixed on a foundation plate through bolts, channel steel is welded on two sides of the foundation plate, a long circular hole is formed in the channel steel, the foundation plate is installed on a fixed support, the fixed support is welded on a machined workpiece and used for supporting the whole floating support, and the fixed support and the foundation plate can move up and down relatively through the long circular hole in the channel steel.

Fine adjustment mechanisms are arranged between the lower spherical tile and the supporting seat and between the fixed support and the foundation plate for adjusting the center of the floating support.

The floating support is basically suitable for all boring machines, not only solves the problem of serious downwarping of the boring rod when boring deep holes or processing a plurality of coaxial holes with larger span, but also expands the processing range of the boring and milling machine and saves the cost of purchasing machine tools again.
