The specific meaning of the above terms in the creation of the present invention can be understood by those of ordinary skill in the art through specific situations.

The invention will be described in detail with reference to the following embodiments with reference to the attached drawings.

A machining supporting tool comprises a base 1, a supporting column 2 installed on the base and a top block 3 installed on the supporting column, wherein the supporting column 2 is shown in figures 1 and 2; the upper end surface of the top block is provided with a groove 4; a plurality of support rods 5 are uniformly distributed on the base by taking the support column as the center, an annular cushion block 6 is arranged between the support rods and the top block, the cushion block is sleeved on the support column, and the cushion block is simultaneously pressed tightly by the support rods; the support rod is provided with a screwing crown 7. Generally, the groove is a V-shaped groove. And the threaded hole on the top block corresponds to the sharp corner of the V-shaped groove.

When a V-shaped groove design is used, in an alternative embodiment, the groove may be in the form of a two-stage bearing surface configuration, as shown in fig. 3. Specifically, the lateral wall of V type recess includes first holding surface 8, be equipped with second holding surface 9 between the top surface of this first holding surface and kicking block, rounding off between first holding surface and second holding surface, the contained angle that the both sides second holding surface formed is greater than the contained angle that the first holding surface in both sides formed, such groove structure design, it has better adaptability to have guaranteed the recess, can support and supplementary fixed to the disc or cylindrical work piece of different diameters, excellent in use effect.

Generally, the diameter of the via hole in the middle of the cushion block is 0.5-1.5mm larger than the outer diameter of the support column, so that the position of the cushion block can be conveniently adjusted in the height direction of the support column. Generally, the supporting rods are uniformly distributed with 2-3 supporting rods.

The cushion up end cooperatees with the terminal surface under the kicking block, forms stable structure cooperation relation, utilizes the bracing piece to strengthen the stability of kicking block, has greatly reduced the vice burden that bears of kicking block and support column threaded connection, especially is getting and puts the in-process, and the impact that the work piece caused to supporting auxiliary fixtures can be effectively solved through the bracing piece that the equipartition set up, and furthest has reduced the kicking block and has taken place the damage that slope or corresponding unbalanced atress lead to.

In an alternative embodiment, the upper end and the lower end of the supporting column are respectively in threaded connection with the top block and the base. The upper end of the supporting column is provided with an upper thread section, the lower end of the supporting column is provided with a lower thread section, the upper thread section is matched with a thread hole formed in the top block, and the lower thread section is matched with a thread hole formed in the base.

Screw hole on the kicking block is seted up at the kicking block lower surface, and the screw hole adopts the blind hole structure, promptly, the screw hole is no matter wear kicking block (last recess), and structural stability is better, and simultaneously, iron fillings, rust or dust particle etc. that drop on the work piece can not get into threaded hole, avoids producing adverse effect to screw-thread fit, has improved the life of frock, and the frock has can long-term stable use and repeatedly usable's advantage.

Generally, the support rod is a full-thread screw, and the screwing crown is arranged at the upper end of the support rod and can be fixed by welding. Of course, it is also possible to use a screw directly as the support rod, the nut portion of the screw being used as the above-mentioned screwing crown. The upper end of the screwing handle head is provided with a working surface matched with the lower surface of the cushion block, the screwing handle head is used for reliably propping against the cushion block, and when the screwing handle head is adjusted in a screwing mode, the cushion block can be adaptively adjusted in height.

The above description is only for the purpose of illustrating the preferred embodiments of the present invention and should not be taken as limiting the invention, so that any modifications, equivalents, improvements and the like, which are within the spirit and principle of the present invention, should be included in the scope of the present invention.
