When the supporting surface is the excircle of the cylinder, the situation of unstable support, insufficient clamping force and insufficient positioning can occur because the positioning surface is a small segment of straight line. In order to overcome the defect, an arc support is added on the upper part of the support mechanism, and the line contact is changed into surface contact. The arc supports more degrees of freedom for limiting the movement of parts, so that the positioning of the supporting mechanism is more accurate; the arc support increases the contact area so that the clamping is more reliable; the arc supports the self-centering function, guides gravity to pass through the axis of the supporting mechanism, and increases the bearing capacity of the support.
The method for adjusting the stroke of the adjusting rod by screwing by hand in the prior art is changed, the round cake shape is adjusted into a hexagon shape, holes are drilled and tapped in the middle, and a detachable auxiliary handle (the length of which can be adjusted) is added, so that the purpose of adjusting the supporting stroke in a small space is achieved; the stroke can also be adjusted with an open-end wrench when the operating space is sufficient.
A positioning hole is processed on the axis of the supporting rod and forms clearance fit with the central column body at the bottom of the arc support so as to achieve the purpose of limiting the horizontal movement and rotation of the arc support. When the support mechanism adjusting rod rotates and moves upwards, the arc support is driven to move upwards without limitation.
A plurality of heterogeneous supports are used in combination, and the flatness and the verticality of a specific surface of a part are adjusted by a small amount.
