[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] like Figures 1-4 As shown, a machine tool balancing adjustment device includes a support 1. A guide rod 2 is fixedly installed on the lower side of the inner surface of the support 1. A lead screw 3 is rotatably installed on the inner surface of the support 1 below the guide rod 2. A limit plate 4 is fixedly installed in the middle of the surface of the guide rod 2. A handwheel 5 is fixedly installed through the support 1 at the right end of the lead screw 3. The same push seat 6 is sleeved on the surface of both the lead screw 3 and the guide rod 2. The push seat 6 is slidably connected to the guide rod 2 and threadedly connected to the lead screw 3. A movable rod 7 is rotatably provided at the upper end of the push seat 6. An adjusting block 8 is rotatably provided at the upper end of the movable rod 7. The surface of the adjusting block 8 is slidably fitted into the interior of the support 1.

[0025] By adopting the above technical solution, the guide rod 2 limits the push seat 6 to prevent the push seat 6 from rotating with the lead screw 3, and ensures that the push seat 6 can move stably when the lead screw 3 rotates.

[0026] Four supports are provided at the corners to support the entire machine tool, serving as fixed support components for the machine tool;

[0027] The upper side of the inner surface of the support 1 limits the adjustment block 8. As the push seat 6 moves, the bottom position of the movable rod 7 changes while the upper position remains unchanged. The overall length of the movable rod 7 does not change. When the lower end of the movable rod 7 gradually approaches the upper end of the movable rod 7 along with the push seat 6, the movable rod 7 will push upward, causing the adjustment block 8 to move up and lift, thereby adjusting the height of different support positions of the machine tool and performing balance adjustment.

[0028] Furthermore, a groove 9 is provided at the bottom of the inner surface of the support 1, and a sliding block 10 is slidably disposed on the inner surface of the groove 9; the upper end of the sliding block 10 is fixedly connected to the push seat 6, and the bottom of the push seat 6 is slidably attached to the lower part of the inner surface of the support 1.

[0029] By adopting the above technical scheme, when the advancing seat 6 moves, the sliding block 10 also moves with the advancing seat 6, and the movement of the sliding block 10 is limited by the sliding groove 9, thereby ensuring stable left-right horizontal movement, and the advancing seat 6 can be adjusted more stably.

[0030] The downward pressure of the adjusting block 8 on the machine tool can be transmitted to the support 1 through the sliding block 10 and the advancing seat 6 itself, so as to avoid the situation that the downward pressure of the adjusting block 8 on the machine tool causes the screw rod 3 and the guide rod 2 to break and bend.

[0031] Further, the upper portion of the support 1 is provided with a mounting base plate 11, and the surface of the mounting base plate 11 is fixedly provided with a level 12 around.

[0032] By adopting the above technical scheme, the mounting base plate 11 is used as the bottom plate of the machine tool for assembly;

[0033] The level 12 can more intuitively observe whether the machine tool is leveled.

[0034] Further, a positioning hole 13 is formed in the outer surface of the support 1 on the right side, and the positioning hole 13 is uniformly distributed around the penetration position of the screw rod 3; a latch 14 is slidingly and penetratingly arranged on the surface of the hand wheel 5, and the left end of the latch 14 is inserted into a certain positioning hole 13.

[0035] By adopting the above technical scheme, the positioning hole 13 limits the rotating direction of the latch 14, and the latch 14 penetrates the hand wheel 5, that is, the rotating of the hand wheel 5 can be limited, and the rotating angle of the screw rod 3 is fixed, thereby avoiding the situation that the hand wheel 5 is affected by external force or the advancing seat 6 is pressed by weight to rotate the screw rod 3 again after leveling.

[0036] Further, a ring plate 15 is fixedly installed on the left side of the surface of the latch 14, and a spring 16 is fixedly installed on the right side of the surface of the ring plate 15; the spring 16 is sleeved outside the latch 14, and the right end of the spring 16 is fixedly connected with the hand wheel 5.

[0037] By adopting the above technical scheme, the spring 16 can push the latch 14 to be stably inserted into the positioning hole 13 through the ring plate 15, so as to prevent the latch 14 from being separated from the positioning hole 13.

[0038] Working principle: when using the machine tool balance adjusting device, first, the machine tool is assembled with the installation base plate 11, the installation base plate 11 carries the machine tool supported by the support 1 at four corners, when the machine tool is inclined, pull out the plug 14 from the positioning hole 13, at this time the hand wheel 5 can be rotated and adjusted, through the hand wheel 5 rotating the lead screw 3, under the limiting of the guide rod 2, make the advancing seat 6 move to the middle, when the advancing seat 6 moves, the sliding block 10 will also move with the advancing seat 6, the movement of the sliding block 10 will be limited by the sliding groove 9, so as to ensure stable left and right horizontal movement, so as to make the movable rod 7 gradually lift, the push top adjusting block 8 is lifted upward, the machine tool is lifted on one side, according to the inclination of the machine tool, the height of the support 1 of each support point of the machine tool can be adjusted uniformly, and the up and down displacement generated is relatively small, so the balance of the machine tool base can be adjusted accurately, after adjustment, the level meter 12 can be used to observe whether the machine tool is leveled more intuitively, the downward pressure of the machine tool is transmitted to the support 1 through the sliding block 10 and the advancing seat 6 itself, which is still supported by the support 1, avoiding the case that the downward pressure of the adjusting block 8 leads to the fracture and bending of the lead screw 3 and the guide rod 2, after determining that the machine tool is leveled, the plug 14 is inserted into the nearest corresponding positioning hole 13, the positioning hole 13 limits the rotating direction of the plug 14, and the plug 14 penetrates the hand wheel 5, that is, the rotating limit of the hand wheel 5 can be realized, which can avoid the secondary rotation of the lead screw 3 caused by the external force of the hand wheel 5 or the extrusion of the advancing seat 6 after leveling, which can ensure the stability of the whole machine tool after leveling, which is the working principle of the machine tool balance adjusting device.
