Description

Technical Field

[0001] This utility model relates to the field of machine tool leveling technology, specifically a leveling device for machine tools. Background Technology

[0002] Machine tools are equipment used to manufacture machines and machinery. They mainly use drills, reamers, taps, dies, and knurling tools to perform corresponding processing. When a machine tool is installed, the bed assembly is made up of multiple bed sections. After the assembly is completed, the machine tool itself needs to be level in order to carry out subsequent processing.

[0003] The applicant found through a search that a Chinese patent discloses "A machine tool leveling device" with publication number "CN219901050U". This patent mainly involves moving a support platform to the bottom of the machine tool, at which point two electric telescopic rods are driven to extend, thereby driving two pressing blocks to move upward. When the pressing blocks move to contact the bottom of the machine tool, the contacts are pressed. If the machine tool is tilted, one contact will contact the bottom of the machine tool. At this time, the hydraulic rod on the same side is driven to drive the push plate to push the machine tool upward until the tops of both pressing blocks contact the bottom of the machine tool. At this time, the machine tool is kept in a horizontal state, avoiding the phenomenon of deviation caused by using shims to level the machine tool.

[0004] The aforementioned device, through a series of structural designs, can adjust the height of both sides of the machine tool, thereby achieving a level position. However, this device has significant limitations in practical applications: because it can only control the lifting of the sides of the machine tool and cannot independently adjust the height of the four corners, it cannot ensure that all support points are on the same horizontal plane when there are differences in the ground support at the four corners. This leads to uneven local stress on the machine tool, affecting the leveling accuracy and ultimately weakening the actual effectiveness of the device. Utility Model Content

[0005] The purpose of this utility model is to provide a leveling device for machine tools, so as to solve the problem that the above-mentioned devices mentioned in the background art cannot independently adjust the four corners of the machine tool during use, thereby affecting the leveling accuracy of the machine tool.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a leveling device for machine tools, comprising four base plates and three levels. A support cylinder is fixedly connected to the top surface of each of the four base plates. Each support cylinder has a leveling assembly inside. The leveling assembly includes a worm gear and a lifting rod. One end of the worm gear is connected to one side of the inner wall of the support cylinder via a bearing, and the other end of the worm gear extends to the surface of the corresponding support cylinder. The outer wall of the lifting rod is slidably connected to the inner wall of the support cylinder. Each of the three levels is equipped with a telescopic assembly.

[0007] Furthermore, the leveling assembly also includes a handle, one side of which is welded to one side of the worm extending to the surface of the corresponding support cylinder.

[0008] Furthermore, the leveling assembly also includes a support block, the bottom surface of which is fixedly connected to the top end of the corresponding lifting rod.

[0009] Furthermore, the leveling assembly also includes a worm gear, the bottom surface of which is rotatably connected to the bottom surface of the inner wall of the support cylinder, one side of which is meshed with one side of the worm, and a lead screw is fixedly connected to the top surface of the worm gear, with the rod wall of the lead screw threadedly connected to the inner wall of the lifting rod.

[0010] Furthermore, the leveling assembly also includes a reinforcing rod and two limiting grooves formed on opposite sides of the inner wall of the support cylinder. The opposite sides of the reinforcing rod are rotatably connected to the opposite sides of the inner wall of the corresponding support cylinder. The inner walls of the two limiting grooves are slidably connected to limiting blocks, and the opposite sides of the two limiting blocks are fixedly connected to the opposite sides of the lifting rod.

[0011] Furthermore, the telescopic assembly includes two telescopic rods, each of which is rotatably connected to one side of a corresponding support block.

[0012] Furthermore, the telescopic assembly also includes two limiting sleeves, with the opposite sides of the two limiting sleeves fixedly connected to the opposite end of the corresponding level, and the inner walls of the two limiting sleeves slidably connected to the outer wall of the corresponding telescopic rod.

[0013] Furthermore, the telescopic assembly also includes two fastening screws, the walls of which are threadedly connected to the inner wall of the corresponding limiting sleeve.

[0014] Compared with the prior art, the beneficial effects of this utility model are: by setting an independently controllable leveling component inside each support cylinder and cooperating with three levels, this utility model can adjust the four corners of the machine tool individually, so that the four corners of the machine tool can be on the same horizontal plane, ensuring the levelness of the machine tool. At the same time, by setting the telescopic component, the position of the four leveling components can be adjusted, making the device applicable to machine tools of various sizes, effectively improving the applicability of the device.

[0022] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0023] Example 1

[0024] like Figures 1 to 4 As shown, a leveling device for a machine tool according to the first aspect of this utility model includes four base plates 1 and three levels 5. The top surfaces of the four base plates 1 are all fixedly connected to support cylinders 4. Each support cylinder 4 is provided with a leveling component 2 inside. The leveling component 2 includes a worm gear 202 and a lifting rod 203. One end of the worm gear 202 is connected to one side of the inner wall of the support cylinder 4 through a bearing, and the other end of the worm gear 202 extends to the surface of the corresponding support cylinder 4. The outer wall of the lifting rod 203 is slidably connected to the inner wall of the support cylinder 4. Each of the three levels 5 is provided with a telescopic component 3.

[0025] The technical effects achieved by the above embodiments are as follows: by setting an independently controllable leveling component 2 inside each support cylinder 4 and cooperating with three levels 5, the four corners of the machine tool can be adjusted individually, so that the four corners of the machine tool can be on the same horizontal plane, ensuring the levelness of the machine tool. At the same time, by setting the telescopic component 3, the position of the four leveling components 2 can be adjusted, so that the device can be applied to machine tools of various sizes, effectively improving the applicability of the device.

[0026] Example 2

[0027] like Figure 1 and Figure 3 As shown, a leveling device for a machine tool includes all the contents of Embodiment 1. In addition, the leveling assembly 2 further includes a handle 201, one side of which is welded to one side of the worm gear 202 extending to the surface of the corresponding support cylinder 4. The leveling assembly 2 also includes a support block 204, the bottom surface of which is fixedly connected to the top end of the corresponding lifting rod 203. The leveling assembly 2 also includes a worm wheel 209, the bottom surface of which is rotatably connected to the bottom surface of the inner wall of the support cylinder 4, and one side of which meshes with one side of the worm gear 202. Next, a lead screw 205 is fixedly connected to the top surface of the worm gear 209. The wall of the lead screw 205 is threadedly connected to the inner wall of the lifting rod 203. The leveling assembly 2 also includes a reinforcing rod 208 and two limiting grooves 206 opened on opposite sides of the inner wall of the support cylinder 4. The opposite side of the reinforcing rod 208 is rotatably connected to the opposite side of the inner wall of the corresponding support cylinder 4. The inner walls of the two limiting grooves 206 are slidably connected to limiting blocks 207. The opposite sides of the two limiting blocks 207 are fixedly connected to the opposite side of the lifting rod 203.

[0028] The technical effects achieved by the above embodiments are as follows: When the worm gear 202 is driven to rotate by the handle 201, the meshing transmission between the worm gear 202 and the worm wheel 209 drives the lead screw 205 to rotate synchronously. Due to the threaded engagement between the lead screw 205 and the lifting rod 203, the lifting rod 203 achieves vertical lifting motion under the sliding constraint of the limiting block 207 and the limiting groove 206. On the one hand, this structure prevents the lifting rod 203 from retracting under load through the self-locking characteristic of the worm wheel 209 and worm gear 202 transmission, ensuring the height stability after leveling. On the other hand, the engagement between the limiting block 207 and the limiting groove 206 effectively eliminates the circumferential rotational freedom of the lifting rod 203, ensuring the linear accuracy of the lifting process, and enabling the support points at each corner of the machine tool to accurately reach the same horizontal plane.

[0029] Example 3

[0030] like Figure 2 and Figure 4As shown, a leveling device for a machine tool includes all the contents of Embodiment 2. In addition, the telescopic assembly 3 includes two telescopic rods 302, both of which are rotatably connected to one side of the corresponding support block 204. The telescopic assembly 3 also includes two limiting sleeves 301, the opposite sides of which are fixedly connected to the opposite end of the corresponding level 5. The inner walls of the two limiting sleeves 301 are slidably connected to the outer walls of the corresponding telescopic rods 302. The telescopic assembly 3 also includes two fastening screws 303, the rod walls of which are threadedly connected to the inner walls of the corresponding limiting sleeves 301.

[0031] The technical effects achieved by the above embodiments are as follows: When adjusting the leveling device to adapt to machine tools of different sizes, the telescopic rod 302 slides within the limiting sleeve 301, and the extension length of the telescopic rod 302 is locked by the fastening screw 303, making the distance between the level 5 and the support block 204 adjustable. This maintains the geometric relationship between the detection benchmark of the level 5 and the support point of the machine tool, and the sliding limit of the telescopic rod 302 by the limiting sleeve 301 prevents deviation during the adjustment process. At the same time, the rotational connection between the telescopic rod 302 and the support block 204 allows the level 5 to adaptively adjust its angle as the leveling assembly 2 rises and falls, ensuring that the measuring plane of the level 5 is always parallel to the leveling plane of the support block 204. The threaded locking mechanism of the fastening screw 303 ensures that the position of the telescopic rod 302 is fixed while preventing loosening caused by machine tool vibration, thereby maintaining leveling accuracy and structural stability when adapting to machine tools of different sizes.

[0032] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
