Description

Technical Field

[0001] This utility model relates to the field of mechanical equipment technology, and more specifically, to a support device for protecting a machine tool worktable. Background Technology

[0002] A machine tool is a machine used to manufacture machines; it is also called a machine tool or mother machine. A machine tool typically consists of the following basic parts: support components, used to install and support other components and workpieces, bearing their weight and cutting forces, such as the bed and column; a speed change mechanism, used to change the speed of the main motion; a feed mechanism, used to change the feed rate; a spindle box for mounting the machine tool spindle; a tool post and tool magazine; a control and operating system; a lubrication system; and a cooling system. Machine tools are generally classified into metal cutting machine tools, forging and pressing machine tools, and woodworking machine tools. Among them, metal cutting machine tools are often used in power engineering, mainly for drilling, reaming, tapping, and other machining operations on workpieces.

[0003] During the production of new machine tools in the factory, machine tool manufacturers undergo assembly, debugging, and testing processes. In these three processes, there are risks of impacts from heavy objects, scratches from heavy objects, and corrosion and oxidation caused by the failure of cutting fluid or other solvents to dry in time. This results in scratches, rust, and oxidation marks on the surface of the new machine tool's worktable. In severe cases, the worktable needs to be repaired, leading to wasted production costs. How to invent a support device to protect the machine tool's worktable and improve these problems has become an urgent problem for those skilled in the art to solve. Utility Model Content

[0004] To overcome the above deficiencies, this utility model provides a support device for protecting machine tool worktables. It aims to improve the problem of rust and oxidation caused by heavy object impacts, heavy object scratches, or failure of cutting fluid or other solvents to dry in time, which can result in scratches, rust, and oxidation marks on the surface of new machine tool worktables. In severe cases, the worktable needs to be repaired, resulting in wasted production costs.

[0005] This utility model is implemented as follows: This utility model provides a support device for protecting a machine tool worktable, including a protective cover plate and a worktable. The worktable is connected to a base assembly, which includes a base nut. The base assembly is connected to a support assembly, which includes a cross block and a support block.

[0006] Preferably, the protective cover is located above the workbench, and the side wall of the protective cover has a plurality of positioning slots.

[0007] Preferably, the side wall of the workbench is provided with a plurality of sliding grooves that cooperate with the positioning slots, and the sliding grooves are arranged in a "T" shape.

[0008] Preferably, the base nut is T-shaped, the base nut is slidably connected to the slide groove, one end of the base nut has a second threaded hole, and both sides of the base nut have guide grooves.

[0009] Preferably, one side of the horizontal block is fixedly connected to the support block, and the side wall of the horizontal block has a through hole.

[0010] Preferably, the side wall of the support block is provided with a first threaded hole, the inner diameter of the first threaded hole is smaller than the width of the guide groove, and a guide screw is threadedly connected to the first threaded hole.

[0011] The beneficial effects of this utility model are: By using support and base components, the worktable surface is protected from direct impacts and scratches, maintaining its original flat and smooth surface. This eliminates physical damage to the worktable, reducing subsequent rework such as grinding and welding. This design cuts off the contact path between liquid and the worktable at the source, preventing metal corrosion and oxidation caused by prolonged liquid retention, ensuring the stability of the worktable material, and reducing the probability of rework due to chemical corrosion. By preventing damage such as impacts, scratches, and corrosion to the worktable, there is no need to rework the new machine tool worktable, saving labor, consumables, and equipment downtime costs during the rework process. At the same time, the protective cover is reusable, eliminating the need for frequent replacements and further reducing consumable investment. This device reduces rework steps through proactive protection, ensuring continuous machine tool production, indirectly shortening the new machine tool delivery cycle, and improving enterprise production efficiency.

[0015] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0016] Example, refer to Figures 1-6 A support device for protecting a machine tool worktable includes a protective cover plate 1 and a worktable 3. The worktable 3 is connected to a base assembly 7, which includes a base nut 71. The base assembly 7 is connected to a support assembly 5, which includes a cross block 51 and a support block 53.

[0017] Furthermore, the protective cover 1 is located above the workbench 3, and the side wall of the protective cover 1 is provided with several positioning slots 2.

[0018] It should be noted that during the operation of this support device, the support block 53, as the core support structure, provides stable height support for the horizontal block 51 through rigid fixation with the horizontal block 51, so that the horizontal block 51 is in a state higher than the upper end of the worktable 3. This structural design fundamentally constructs a "physical isolation layer between the protective cover plate 1 (or workpiece) and the worktable 3 surface". When the protective cover plate 1 is placed on the horizontal block 51 and fixed, a certain gap is always maintained between the bottom of the protective cover plate 1 and the worktable 3 surface, and no direct contact occurs, forming a reliable protective barrier. From the perspective of preventing physical damage, during the assembly, debugging, and testing phases of machine tools, accidental drops of heavy objects during handling and frictional collisions during tool placement are inevitable. In these situations, because the protective cover 1 is directly above the worktable 3 and bears the external force, heavy objects or tools will first contact the protective cover 1, rather than directly impacting or scratching the surface of the worktable 3. The protective cover 1 can absorb the impact force through its own structural strength, preventing physical damage such as dents and scratches on the surface of the worktable 3, and maintaining the original flat and smooth surface of the worktable 3, eliminating the need for rework such as grinding or welding due to surface damage. From the perspective of preventing chemical corrosion, liquids commonly used in machine tool operation, such as cutting fluids and cleaning solvents, can cause damage if they come into direct contact with the worktable. If the surface of workbench 3 is not cleaned in time, prolonged accumulation of liquid can easily lead to a chemical reaction with the metal material of the workbench, resulting in problems such as rust and oxidation. In this device, the gap between the protective cover plate 1 and the workbench 3 forms a "liquid guide channel": on the one hand, the protective cover plate 1 can directly block liquid from dripping onto the surface of workbench 3; on the other hand, even if a small amount of liquid seeps into the gap along the edge of the protective cover plate 1, it will quickly flow out of the workbench 3 and will not accumulate on the surface of workbench 3. This design cuts off the contact path between the liquid and workbench 3 from the source, completely avoiding rust and oxidation problems caused by liquid retention, significantly reducing the probability of rework due to chemical corrosion of workbench 3, and reducing unnecessary maintenance costs and production delays.

[0019] Reference Figures 4-6 Furthermore, the side wall of the workbench 3 is provided with several sliding grooves 4 that cooperate with the positioning slots 2, and the sliding grooves 4 are arranged in a "T" shape; the base nut 71 is arranged in a "T" shape, and the base nut 71 is slidably connected to the sliding grooves 4. One end of the base nut 71 is provided with a second threaded hole 73, and both sides of the base nut 71 are provided with guide grooves 72; one side of the horizontal block 51 is fixedly connected to the support block 53, and the side wall of the horizontal block 51 is provided with a through hole 52; the side wall of the support block 53 is provided with a first threaded hole 54, the inner diameter of the first threaded hole 54 is smaller than the width of the guide groove 72, and the first threaded hole 54 is threadedly connected with a guide screw 6.

[0020] It should be noted that the support fixture assembly consists of a base nut 71, a horizontal block 51, and a support block 53 forming a basic combination unit. The two are connected by guide screws 6. The screws pass through the first threaded holes 54 on both sides of the support block 53, restricting the base nut 71 within the range of motion of the guide groove 72 of the support block 53, forming a "non-separable assembly" (which can also be disassembled and used separately in actual use). This combination design facilitates the overall handling and placement of the fixture, and ensures the stability of the relative positions of the two during subsequent operations, avoiding the impact of misalignment on the protective effect. The assembled fixture is placed inside the "T"-shaped slide groove 4 of the machine tool worktable 3. At this time, due to the action of the support block 53, the horizontal block 51 is higher than the table surface of the worktable 3, reserving isolation space for the subsequent placement of the protective cover plate 1. After the protective cover plate 1 (or workpiece) is placed on the horizontal block 51, the screw passes through the positioning slot 2 and the through hole 52 and is threaded to the second threaded hole 73 on the base nut 71, thereby applying an upward pulling force. Under the action of the pulling force, the base nut 71 moves upward, and its side step fits tightly against the inner wall of the slide 4 on the worktable 3. At the same time, the horizontal block 51 is subjected to the pressure of the protective cover plate 1, which makes the support block 53 fit tightly against the bottom of the slide 4. Through the bidirectional force of "the base nut 71 being pulled and pressed against the wall of the slide 4, and the support block 53 being pressed and pressed against the bottom of the slide 4", the tooling assembly and the worktable 3 form a stable connection, thereby firmly fixing the protective cover plate 1 (or workpiece).

[0021] It should be noted that the specific model and specifications need to be selected and determined based on the actual specifications of the device. The specific selection and calculation method adopts the existing technology in this field, so it will not be described in detail here.

[0022] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
