[0002] In the field of mechanical processing, many casting blanks have uneven surfaces. When rough machining is performed, in addition to positioning and clamping, auxiliary support is also required to meet the clamping requirements of rough machining. The traditional auxiliary support method is a combination of bolts and nuts, which are supported at the lower end of the blank to achieve auxiliary support. Traditional auxiliary supports often become loose during rough machining due to large cutting volume, resulting in abnormal rough machining quality, a slightly longer clamping time and certain complexity, and certain requirements for workers' operation. In order to reduce the complexity of clamping operations and improve product quality, it is necessary to develop a new auxiliary support component. Summary of the invention

[0005] The vertical adjustment assembly includes a lifting screw, a lifting nut, and a locking nut. The lifting nut is placed in a waist-shaped through hole, and the locking nut is placed on the upper surface of the upper boss and aligned with the bolt hole. The lifting screw is screwed into the locking nut, the bolt hole, and the lifting nut in sequence from top to bottom to form a threaded secondary structure.

[0006] The self-balancing auxiliary support assembly includes an auxiliary support block, a positioning pin and two groups of angular pins; the auxiliary support block is a bow-shaped structure with a middle part protruding upward, installed in the installation groove of the lifting screw and positioned by the positioning pin; a pin hole is respectively provided at the bottom of both ends of the auxiliary support block, the upper part of the angular pin is clearance-matched with the pin hole to form a rotatable installation, and the lower part is clearance-matched and installed in the positioning groove.

[0007] The four corners of the lower boss are provided with four screw holes, which are connected to the bottom plate of the existing tooling through screws.

[0008] There are multiple fixed support blocks installed on one side of the self-balancing auxiliary support assembly.

[0009] The working method includes the following steps: Step 1: Rotate the lifting nut to drive the lifting screw to rotate, so as to realize the up and down movement of the thread pair, so that the auxiliary support block abuts against the bottom surface of the casting blank; Step 2: The angular pin follows the auxiliary support block to move up and down in the positioning groove in the vertical direction to ensure the angular positioning of the auxiliary support block; Step 3: Since the positioning pin does not limit the rotational freedom of the auxiliary support block, self-balancing adjustment is achieved in the process of contacting the casting blank; the casting blank is supported together with other fixed support blocks; Step 4: Finally, tighten the locking nut and lock the lifting screw, thereby realizing the locking function of the self-balancing auxiliary support assembly to prevent the casting blank from loosening during the processing; Step 5: Process the casting blank normally.

[0010] Compared with the prior art, the present invention has the following beneficial technical effects: 1. The present invention is an auxiliary support assembly for casting blanks during mechanical rough machining, which ensures that the casting blanks are positioned and clamped in a certain manner, and realizes stable auxiliary support. The auxiliary support block can be moved up and down by rotating the lifting nut, and at the same time, the two points of the auxiliary support block are automatically balanced to achieve auxiliary support. The locking nut is then used to prevent the auxiliary support block from loosening due to vibration during mechanical rough machining such as cutting, thereby reducing the complexity of operation.

[0011] 2. The present invention can be used for auxiliary support of clamping of other processing equipment such as turning and milling, with simple structure and convenient operation. It cooperates with the fixed support block to support the casting blank, replacing the traditional single fulcrum auxiliary support principle and improving the clamping efficiency of the casting blank during processing.
