[0002] In mold processing, the mold needs to be processed through processes such as cutting, grinding, and polishing to form the required shape, and then the mold can be used for the production and processing of products.

[0003] Among them, the mold needs to be repeatedly debugged before leaving the factory, that is, the mold after preliminary processing is subjected to trial molding, and after the trial molding, the position that needs to be adjusted is found according to the situation of the product, and then the mold is placed on the carving and grinding machine for grinding and polishing to correct the position that needs to be adjusted.

[0004] Among them, the existing molds are directly placed on the working plane of the carving and grinding machine, and the working plane is non-adjustable, so that there is a certain height deviation when the mold is placed on the working plane during the repeated debugging process, that is, the mold is inclined so that one side is high and the other side is low. This height deviation is usually small, between a few silk and a few millimeters, and cannot be distinguished by the naked eye. This height deviation causes the overall shape of the mold to change during the numerical control grinding and polishing process, affecting the accuracy of the produced products. For products with high-precision requirements, the mold will be directly scrapped. Summary of the Utility Model

It should be noted that the following are only some specific embodiments of the concept of the present utility model and only a part of the embodiments of the present utility model. The specific and direct descriptions of the relevant structures are only for the convenience of understanding the present utility model, and the specific features do not of course and directly limit the scope of implementation of the present utility model. Routine selections and substitutions made by those skilled in the art under the guidance of the concept of the present utility model shall be regarded as within the scope of protection required by the present utility model.

[0038] Embodiment 1:

[0039] As Figures 1 - 5 shown, the present utility model discloses an adjustable leveling workbench, comprising:

[0040] Workbench 1, on the upper side of the workbench 1, a support plane 11 and a plurality of leveling positions 12 surrounding the outer periphery of the support plane 11 are provided, and threaded holes 13 are vertically penetrated on the leveling positions 12;

[0041] Multiple groups of leveling assemblies 2, the leveling assembly 2 includes a support member 21 and a leveling screw 22, the support member 21 is located below the leveling position 12, the leveling screw 22 is in threaded fit with the threaded hole 13 of the leveling position 12, and the lower end of the leveling screw 22 is rotationally fitted with the support member 21.

[0042] Therefore, 1. Place the mold 6 to be corrected on the support plane 11, and use a vernier caliper to detect each position in the circumferential direction of the mold 6 to determine which side of the mold 6 is higher and which side is lower at the current position. Then, operate the leveling component 2 on the leveling position 12 to lower the higher side of the mold 6 and raise the lower side, so as to ensure that the mold 6 undergoing reciprocating debugging maintains the same state when placed on the engraving machine multiple times to ensure processing accuracy. 2. The leveling screw 22 rotates to lift and lower the leveling position 12 with which it is in threaded engagement. During the lifting and lowering process, the leveling screw 22 will deflect to adapt through the rotational cooperation of the leveling screw 22 and the support member 21, and the support member 21 stably supports the workbench 1.

[0043] Preferably, the workbench 1 is in the shape of a cuboid, and the number of both the leveling positions 12 and the leveling components 2 is four, which are respectively located at the four corner ends of the workbench 1.

[0044] Therefore, the cuboid-shaped workbench 1 better adapts to the conventional mold 6 with a square bottom, and the setting of the leveling components 2 at the four corner ends enables more stable force support and more convenient adjustment.

[0045] Specifically, in this embodiment, the upper end of the support member 21 is provided with a spherical arc-shaped abutting groove 211, and the lower end of the leveling screw 22 is provided with a spherical arc-shaped abutting head 221. The abutting head 221 is placed in the abutting groove 211, and the outer peripheral wall of the abutting head 221 is in contact with the inner peripheral wall of the abutting groove 211 to achieve rotational cooperation.

[0046] Preferably, by setting the upper end of the abutting groove 211 to be lower than the center of the spherical arc-shaped abutting groove 211 so that the radius of the upper end of the abutting groove 211 is smaller than the radius of the spherical arc-shaped abutting groove 211, and forming a disassembly and assembly opening at the upper end of the abutting groove 211, the abutting head 221 can enter and exit the abutting groove 211 through the disassembly and assembly opening to realize the disassembly of the support member 21 and the leveling screw 22.

[0047] In addition, the leveling component 2 in this embodiment includes a locking member 23. The outer periphery of the locking member 23 is cylindrical, and the inner periphery of the locking member 23 is in threaded engagement with the leveling screw 22. Thus, after the leveling screw 22 is rotated and adjusted, by keeping the leveling screw 22 stationary and rotating the locking member 23 until it abuts against the upper surface of the leveling position 12, the downward spiral rotation of the leveling screw 22 is restricted to maintain stability.

[0048] In addition, a placement surface 14 is provided below the workbench 1 in this embodiment, so that the workbench 1 can be directly placed through the placement surface 14 when the leveling component 2 is not needed.

[0049] Preferably, the bottom of the workbench 1 is hollowed out so that the placement surface 14 is annular, making the overall weight of the workbench 1 smaller. Additionally, the cylindrical portion 15 and multiple ribs 16 are arranged within the hollowed-out area, with each rib 16 surrounding the outer periphery of the cylindrical portion 15. The upper side of the rib 16 is integrally formed with the top wall of the hollowed-out area, one end of the rib 16 is integrally formed with the outer peripheral wall of the cylindrical portion 15, and the other end of the rib 16 is integrally formed with the inner peripheral wall of the hollowed-out area, thereby achieving the support of the support plane 11 by the cylindrical portion 15 and the ribs 16 to improve the support capacity.

[0050] In addition, an inner area 17 is provided below the leveling position 12 of the workbench 1 in this embodiment. The inner area 17 is used to place the support member 21 within the inner area 17 when the leveling component 2 is not needed, so that the lower surface of the support member 21 is parallel to or higher than the placement surface 14.

[0051] Therefore, when the leveling component 2 is not needed, the leveling component 2 does not need to be disassembled from the leveling position 12. It can be directly placed into the inner area 17 to achieve support only through the placement surface 14, preventing the leveling screw 22 from being continuously stressed and affecting the durability of the threaded connection. Additionally, for the processing of the mold 6 with relatively low precision requirements, it can be directly placed through the placement surface.

[0052] Preferably, a driving head 222 is provided above the leveling position 12 of the leveling screw 22 in this embodiment, enabling the operator to directly rotate the driving head 222 above the leveling position 12 to drive the rotation of the leveling screw 22.

[0053] In addition, a U-shaped positioning portion 18 is convexly provided on the support plane 11 in this embodiment. The positioning portion 18 includes a first body portion 181, a second body portion 182, and a third body portion 183 that are sequentially connected and are in a strip shape. The length directions of the first body portion 181 and the third body portion 183 are along the front-rear direction, and the first body portion 181 and the third body portion 183 are arranged opposite to each other left and right. The length direction of the second body portion 182 is along the left-right direction, and both ends of the second body portion 182 are respectively connected to the rear ends of the first body portion 181 and the second body portion 182. An access opening 184 is provided between the front ends of the first body portion 181 and the third body portion 183.

[0054] Therefore, the mold 6 to be placed on the support plane 11 can be initially placed in front of the access opening 184 and then pushed backward between the positioning portions 18. After that, it can be positioned in the left-right direction through the first body portion 181 and / or the third body portion 183, and positioned in the front-rear direction through the second body portion 182, making the positioning more accurate.

[0055] Embodiment 2:

[0056] As Figure 6 shown, a carving and grinding machine includes:

[0057] A frame 3 is provided with a workbench surface 31 thereon.

[0058] A grinding head 4;

[0059] A driving assembly 5. Among them, the driving assembly 5 is used to drive the grinding head 4 to rotate at a high speed and control the displacement and deflection of the grinding head 4. Among them, the driving assembly 5 is a mature design in a numerical control machine tool and is not the main inventive point of this patent, so no detailed description will be made here;

[0060] The adjustable leveling workbench described in the first embodiment is arranged on the workbench surface 31.

[0061] Place the mold 6 to be corrected on the support plane 11, and then adjust it through the leveling assembly 2 and then process it under the work of the grinding head 4 and the driving assembly 5.

[0062] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present utility model. Various modifications to these embodiments will be obvious to those skilled in the art, and the general principles defined herein can be implemented in other embodiments without departing from the spirit or scope of the present utility model.
