Lifting base bracket

Abstract

The invention discloses a lifting base bracket, and relates to the field of mechanical part machining. The lifting base bracket is provided with a workbench. The workbench is provided with a plurality of pedestals. Calibration structures are arranged between the pedestals and the workbench. The side surface of each pedestal is provided with a first water drop horizontal calibration piece. Each pedestal is provided with an extensible supporting rod. The upper end of each extensible supporting rod is provided with a second water drop horizontal calibration piece. A hold-down nut is arranged on each extensible supporting rod and located below the corresponding second water drop horizontal calibration piece. A detachable pressing plate is arranged on each extensible supporting rod and located below the corresponding hold-down nut. The extensible supporting rods are adjusted so that the detachable pressing plates can tightly press machined parts. The lifting base bracket aims to solve the calibration problem by adding the calibration structure, the first water drop horizontal calibration pieces and the second water drop horizontal calibration pieces.

Description

technical field

[0001] The invention relates to the field of machining of mechanical parts, in particular to a lifting seat bracket. Background technique

[0002] At present, the drill bit of the hole drilling machine is slender, and the two ends of the drill bit are respectively subjected to torque in opposite directions. When the guide rail of the deep hole drilling machine slides to process deep holes, the relative position of the main shaft and the guide rail is prone to deviation under the action of torsional force, which makes the main shaft and the drill bit vibrate, resulting in drilling deviation and drill bit damage. Therefore, During processing, the stability of the spindle is poor, the processing precision is low, and it takes a lot of debugging time, which reduces the production efficiency.

[0003] Now the publication number is CN203292932U, which discloses a support frame for positioning the main shaft of a deep hole drilling machine, including a bracket and ...

Embodiment 1

[0031] Embodiment one, such as figure 1 , figure 2 , image 3 and Figure 4 The lifting seat bracket has a workbench 1, and several bases 2 are arranged on the workbench 1, and the base 2 is riveted on the workbench 1 through rivets. This application considers the cost and the time consumed for replacing the processing parts, and now we can set up six A base of 2 is the optimal setting. Fixing pieces 13 are arranged on the workbench 1 around the base 2 to fix the processing parts.

[0032] A calibration structure 3 is provided between the base 2 and the workbench 1. The calibration structure 3 includes lower and upper channels 11 and 22 respectively set on the workbench 1 and the base 2, and between the lower and upper channels 11 and 22. A calibration block 6 is provided, and is riveted with the workbench 1 by penetrating the base 2 and the calibration block 6 with two rivets. The calibration block 6 is partly outside the base 2 and exposed on the workbench 1 .
