[0002] Granite has a high yield rate, can be processed in various ways, and its slabs can be easily assembled. Furthermore, granite is not easily weathered, making it suitable for outdoor decorative stone. After rough shaping, the quarried granite blocks are called raw blocks, which are then manually drilled and wedge-shaped or machine-sawed to obtain blocks and slabs of the required dimensions. These are then processed using milling machines or lathes into cylindrical or curved shapes. Finally, coarse and fine rock-like textures are chiseled by hand, or machine grinding and polishing are used to achieve a bright, crystalline surface. When positioning cylindrical granite, simple V-blocks are mainly used for support and positioning, which is inconvenient for adjusting cylindrical granite of different lengths, causing inconvenience in use. Summary of the Invention

[0003] The purpose of this invention is to provide a cylindrical granite V-shaped block positioning device to solve the above-mentioned problems.

[0016] The present invention will be further described below with reference to the accompanying drawings: like Figures 1-5 As shown, a cylindrical granite V-shaped block positioning device includes a base frame 1, an adjustment mechanism for relative movement adjustment is provided on the base frame 1, and a positioning mechanism is fixed relative to the adjustment mechanism. In this embodiment: the adjustment mechanism includes a support shaft 21 vertically rotatably mounted on the base frame 1. A gear 24 is fixedly mounted on the support shaft 21 on the upper side of the base frame 1. A power assembly is connected to the lower side of the support shaft 21. A horizontally parallel sliding groove 11 is arranged on the upper end of the base frame 1, located on the front and rear sides of the support shaft 21. A slide rail 26 is slidably arranged in the sliding groove 11. A rack 25 is fixedly mounted on the upper end of the slide rail 26. The teeth of the rack 25 are arranged opposite each other and mesh with the gear 24. The power assembly includes a support shaft 21 fixed to the base frame 1. The worm gear 22 is located at the lower end of the shaft 21. A worm 23 is meshed on one side of the worm gear 22. A handwheel is installed at the front end of the worm 23 through the bottom frame 1. The worm 23 is rotatably connected to the bottom frame 1. By rotating the worm 23 to mesh with the worm gear 22, the gear 24 on the support shaft 21 is driven to rotate. The gear 24 meshes with the racks 25 on the front and rear sides, causing the racks 25 and the slide rail 26 to move relative to each other under the limit of the slide groove 11. This causes the spacing between the positioning mechanisms at the ends of the front and rear racks 25 to change, so as to meet the positioning needs of cylindrical granite stones of different lengths.

[0017] In this embodiment: the positioning mechanism includes a mounting plate 31 fixed to the upper end of the rack 25, a V-shaped support 32 fixed to the upper end of the mounting plate 31, connecting seats 33 provided on the front and rear sides of the V-shaped support 32, a crossbeam 34 mounted on the connecting seats 33, and a clamping assembly provided on the crossbeam 34; the clamping assembly includes a screw 35 vertically mounted on the crossbeam 34, an upper V-shaped seat 36 provided at the lower end of the screw 35, a vertical groove 341 provided on the inner opposite surface of the crossbeam 34, and the upper V-shaped seat 36 slidably connected to the vertical groove 341; the screw 35 is threadedly connected to the crossbeam 34, and the screw 35 is rotatably connected to the upper V-shaped seat 36; by rotating the screw 35, the screw 35 pushes... The upper V-shaped seat 36 moves downward under the limit of the vertical groove 341, pressing and positioning the cylindrical granite placed on the V-shaped support 32. The V-shaped support 32 has a relief groove in the middle to allow the upper V-shaped seat 36 to move downward, so that the upper V-shaped seat 36 can move into the V-shaped support 32 when it moves downward, improving the fixing of the cylindrical granite. The cross frame 34 is rotatably connected to the rear connecting seat 33 by a pin, and the cross frame 34 is detachably connected to the front connecting seat 33 by a movable shaft, which makes it easy to rotate the cross frame 34 relative to the V-shaped support 32, so that the V-shaped support 32 is in a fully open state, improving the convenience of picking up and putting down the cylindrical granite.

[0018] The working principle and usage process of this utility model are as follows: When positioning and supporting a cylindrical granite, the spacing between the positioning mechanisms on both sides is adjusted according to the length of the cylindrical granite. By rotating the worm gear 23 and meshing with the worm wheel 22, the gear 24 on the support shaft 21 is driven to rotate. The gear 24 meshes with the racks 25 on the front and rear sides, causing the racks 25 and the slide rail 26 to move relative to each other under the limit of the slide groove 11, so that the spacing between the positioning mechanisms at the ends of the front and rear racks 25 changes, and the cylindrical granite is placed on the V-shaped support 32. The crossbeam 34 rotates forward, and the front connecting seat 33 is connected and limited to the crossbeam 34 through the movable shaft. Then, the screw 35 is rotated, so that the screw 35 pushes the upper V-shaped seat 36 to move downward under the limit of the vertical groove 341, pressing the cylindrical granite on the V-shaped support 32, thus completing the positioning of the cylindrical granite.

[0019] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
