Detailed Description

The invention is further illustrated by the following examples.

A novel jack with a rotatable V-shaped dislocation supporting rod comprises a supporting square rod, a supporting seat, an adjusting screw rod, a base, a steel ball cover plate and a steel ball as shown in figures 1-5; the two supporting square rods are inserted on the supporting seat in a staggered manner and are in surface contact with each other in a staggered manner, so that the two supporting square rods do not support stress on one working plane; the supporting square rod can rotate on the supporting seat; adjusting screw lower extreme spiro union is at base upper surface center, the lower surface mounting steel ball of base, adjusting screw's upper end is connected supporting seat and supporting seat adjusting screw relatively rotate, and adjusting screw can be along with the steel ball free movement and rotate on the base, and then during the support part, can realize automatic change axial direction when rotating adjusting screw adjustment jack height. The novel jack of the invention has the following characteristics:

1. the included angle of the two supporting square rods is preferably 90 degrees, each supporting square rod can rotate freely, parts which are freely and tightly attached to the supported parts can be achieved, and the cylinder and the cone can be firmly supported.

2. 2 support square poles of pegging graft on the supporting seat, 2 grafting mounting holes on the supporting seat are not on a plane, and 2 support square poles do not also support the atress on a working plane like this to avoided 2 to support square poles when supporting the cone, interference that the V-arrangement root probably appears, can freely closely laminate moreover and support cone and cylinder from little to big, arbitrary diameter size.

3. The supporting square rods and the supporting square rods adopt a splicing mode, a plurality of supporting square rods can be spliced, arbitrary lengthening is realized, and the positions of the long and short supporting square rods (figures 6 and 7) can be interchanged, so that cones and cylinders with arbitrary diameter sizes can be supported.

4. Because the supporting square rods are connected in an inserting mode, the supporting square rods can adopt various materials with different hardness for the supported piece, and the appearance of the supported piece is guaranteed not to be scratched and damaged during supporting work.

5. Three steel balls are arranged under the large base, so that the jack can freely and smoothly move and rotate on the working platform. Because the support square rod can rotate on the support seat, the support seat can rotate in the adjusting screw rod, and the adjusting screw rod freely moves and rotates along with the steel ball on the large base, when supporting a part, the four handles on the adjusting screw rod are rotated, and the axial center of the automatic part-changing piece can be realized when the height of the jack is adjusted.

FIG. 8 shows a preferred embodiment of a support base comprising a support square bar mounting block and a cylinder; the bottom surface of the supporting square rod mounting block is provided with a cylinder which is used for being connected with the adjusting screw rod, the top surface is provided with two inclined planes which are staggered and form an angle with each other, and the two inclined planes are provided with unthreaded holes for mounting the supporting square rod.

Fig. 9 shows a preferred example of the adjusting screw, which is composed of a lower threaded rod and an upper cylinder, wherein the handles (4 in this example) are circumferentially distributed on the upper cylinder, and the upper end of the adjusting screw is provided with a light hole for matching with the supporting seat cylinder, and the light hole is a non-through hole.

Examples

1. 3 steel balls with diameter of 15 mm are loaded into 3 hemispherical pits under a large base (figure 10), and a steel ball cover plate (figure 11) is covered and fastened by 9M 3 screws. The machining tolerance of the hemispherical pits is 0.05mm larger than that of a single surface of the steel ball, and 3 steel balls can smoothly and freely roll after the screw is tightened.

2. The screw of M20 x 1.5 of the adjusting screw is screwed into the large base from the side without the steel ball.

3. A cylinder with a diameter of 12 mm below the support seat is inserted into a hole with a diameter of 12 mm in the center of the upper surface of the adjusting screw. The machining tolerance of a cylinder with the diameter of 12 mm is 0.03mm smaller than that of a single surface of the hole.

4. Finally, 2 cylinders with the diameter of 10 mm for supporting the rectangular rod are inserted into the 2 holes on the supporting seat. The processing tolerance of a cylinder with the diameter of 10 mm on the supporting rectangular rod is 0.03mm smaller than that of the single surface of the hole.

5. By now the installation is complete, it can be used. The jack can support the cylinder and the cone with the diameter of less than 100 mm and any diameter size. When a part with a larger diameter size needs to be supported, the effect can be quickly realized as long as the lengthened supporting square rods are continuously inserted.
