Description

Technical Field

[0001] The present invention relates to the technical field of machine tool processing, and more particularly to an insulating conductive partition workbench. Background Art

[0002] With the continuous development and application of high-precision machine tools, tool wear has become increasingly significant in affecting precision machining. Tool wear not only leads to workpiece dimensional deviations and reduced surface quality, but can also cause risks such as chatter and chipping, severely restricting machining efficiency and the yield rate of finished products. Tool wear can occur in various types, including abrasive wear caused by friction between the tool and the workpiece; mechanical damage such as adhesive wear caused by softening the tool material due to excessive cutting temperatures; and micro-discharge and electro-corrosion damage caused by voltage differences. Micro-discharge damage is a key but often overlooked cause of tool damage.

[0003] During high-precision machining, a voltage difference can form between the spindle and worktable due to a variety of reasons: differences in electrode potential caused by the different materials of machine tool components (such as a steel spindle and a cast iron worktable); static electricity accumulation caused by friction during cutting; or stray currents caused by leakage in the machine tool's electrical system. When the tool contacts the workpiece (especially highly conductive materials like copper and aluminum), the cutting area alternates between contact and microgap states: contact forms a conductive circuit, while microgap states create an electric field due to the voltage difference, causing air or cutting fluid in the gap to break down, resulting in transient microdischarges.

[0004] These micro-discharges generate localized high temperatures (up to thousands of degrees Celsius in a split second), which ablate the tool surface, causing microscopic pitting and oxidation at the cutting edge. Over time, these conditions can dull the tool edge and cause chipping, shortening tool life and further exacerbating machining errors due to unstable cutting forces. Summary of the Invention

[0005] The present invention provides an insulated conductive partition workbench to solve the problem that when existing machine tools process a workpiece, a conductive circuit is formed when the workpiece contacts the tool. When there is a micro gap, an electric field is generated due to the voltage difference, causing the air or cutting fluid in the gap to be broken down, forming an instantaneous micro-discharge, thereby ablating the tool surface, causing microscopic pitting and oxidation on the cutting edge. Over a long period of time, the tool edge will gradually become blunt and notches will appear, which will not only shorten the tool life, but also further aggravate the processing error due to unstable cutting force.

[0006] To achieve the above object, the present invention provides the following technical solution: an insulating conductive partition workbench, comprising: The workbench body includes a bottom plate, an insulating plate and a top plate. The bottom plate, the insulating plate and the top plate are stacked in sequence from bottom to top. The contact surface between the bottom plate and the machine tool is sprayed with insulating paint. The insulating plate is made of insulating material. The bottom plate and the top plate are spaced apart.

[0008] In a preferred embodiment, a plurality of mounting holes are provided on the top of the top plate, and the plurality of mounting holes are divided into four groups. The four groups of mounting holes are used to connect and fix the insulating plate and the top plate.

[0009] In a preferred embodiment, an isolation mechanism is provided on the top plate, the isolation mechanism includes an isolation cover, the insulation plate is arranged in a trapezoidal shape, and the upper and lower ends of the insulation plate are connected, and the isolation cover is arranged around the outside of the top plate.

[0010] In a preferred embodiment, two groups of connecting plates are provided on the insulating cover. The two groups of connecting plates are respectively located on both sides of the top plate. The connecting plates are used to connect and fix the insulating cover and the top plate.

[0011] In a preferred embodiment, a sealing assembly is provided on the isolation cover, and the sealing assembly includes two groups of seals, each group of seals includes a sealing strip 1 and a sealing strip 2, and the two groups of seals are arranged around the circumference of the top plate to seal the gap between the top plate and the isolation cover.

[0012] In a preferred embodiment, a filling strip is provided on one side of the sealing strip 1 and the sealing strip 2 close to the top plate, and a slot is provided on the filling strip on the sealing strip 2, which is adapted to fit the sealing strip 1.

[0013] In a preferred embodiment, a sealing groove 1 is provided on the peripheral side of the top plate, and the filling strip is adapted to the sealing groove 1.

[0014] In a preferred embodiment, a second sealing groove is provided on the top of the isolation cover, and both the first sealing strip and the second sealing strip are adapted to the second sealing groove.

[0015] In a preferred embodiment, a groove is provided at the bottom of one side of the connecting plate close to the top plate, and the groove is adapted to fit the sealing member.

[0028] The present application is described in further detail below in conjunction with the accompanying drawings. It is necessary to point out that the following specific implementation methods are only used to further illustrate the present application and cannot be understood as limiting the scope of protection of the present application. Technicians in this field can make some non-essential improvements and adjustments to the present application based on the above application content.

[0029] Example 1 Refer to the instruction manual Figures 1 to 10The present invention proposes an insulated conductive partition workbench to solve the problem in the prior art that when a machine tool is machining a workpiece, a conductive circuit is formed when the workpiece and the tool come into contact. When there is a micro gap, an electric field is generated due to the voltage difference, which causes the air or cutting fluid in the gap to be broken down, forming an instantaneous micro-discharge, thereby ablating the tool surface, causing microscopic pitting and oxidation on the cutting edge. Over a long period of time, the tool edge will gradually become blunt and notches will appear, which will not only shorten the tool life but also further aggravate the processing error due to unstable cutting force, including: The workbench body 1 includes a bottom plate 11, an insulating plate 12 and a top plate 13. The bottom plate 11, the insulating plate 12 and the top plate 13 are stacked in sequence from bottom to top. The contact surface between the bottom plate 11 and the machine tool is sprayed with insulating paint. The insulating plate 12 is made of insulating material. The bottom plate 11 and the top plate 13 are spaced apart.

[0030] It should be noted that the insulating paint sprayed on the contact surface between the base plate 11 and the machine tool can be selected according to the actual use of the machine tool. For example, alkyd resin insulating paint, epoxy insulating paint and silicone insulating paint, etc. At the same time, the integrity of the insulating paint layer needs to be regularly inspected, and any gaps need to be repaired in a timely manner. This is a mature technology well known to those skilled in the art and will not be described in detail in this embodiment. The insulating plate 12 is a sandwich plate made of marble and is disposed between the bottom plate 11 and the top plate 13 to physically isolate the two.

[0031] In this embodiment, the implementation scenario is specifically as follows: by providing an insulating plate 12 made of marble and spraying insulating paint on the bottom of the base plate 11, double insulation measures are used to achieve physical isolation of the top plate 13 from the body of the machine tool, effectively avoiding the stray current caused by poor grounding and leakage of the electrical system of the machine tool to be transmitted to the top plate 13, thereby causing electrical corrosion to the tool when the machine tool processes the workpiece, and significantly improving the service life of the tool.

[0032] The top of the top plate 13 is provided with a plurality of T-slots 14 in an array, and the T-slots 14 are used to fix the workpiece.

[0033] It should be noted that the workpiece can be fixed on the top of the top plate 13 by bolts or a special fixture in conjunction with the T-slot 14, thereby facilitating processing.

[0034] A plurality of mounting holes 15 are provided on the top of the top plate 13 . The plurality of mounting holes 15 are divided into four groups. The four groups of mounting holes 15 are used to connect and fix the insulating plate 12 and the top plate 13 .

[0035] It should be noted that the insulating plate 12 and the top plate 13 can be connected and fixed by bolting, which is a mature technology well known to those skilled in the art and will not be described in detail in this embodiment.

[0036] Example 2 Based on Example 1, refer to the attached Figures 1 to 10 This embodiment proposes an isolation mechanism 2 to solve the problem in the prior art that, after the machine tool has been used for a long time, cutting fluid and workpiece waste chips are easily attached to the outer surface of the worktable body 1 to form a "thin film" connected to the machine tool, causing the top plate 13 and the body of the machine tool to be reconnected, resulting in the problem of tool damage.

[0037] The top plate 13 is provided with an isolation mechanism 2 , which includes an isolation cover 21 . The insulation plate 12 is arranged in a trapezoidal shape, with the upper and lower ends of the insulation plate 12 being connected. The isolation cover 21 is arranged around the outside of the top plate 13 .

[0038] It should be noted that the insulating cover 21 can be made of plastic material, and the opening area of ​​its bottom end is larger than the cross-sectional area of ​​the insulating plate 12 and the bottom plate 11, and sufficient gap is reserved between the bottom end of the insulating cover 21 and the bottom plate 11 and the insulating plate 12. This is a mature technology well known to people in this field and will not be repeated in this embodiment.

[0039] Two groups of connecting plates 22 are provided on the isolation cover 21 . The two groups of connecting plates 22 are respectively located on both sides of the top plate 13 . The connecting plates 22 are used to connect and fix the isolation cover 21 and the top plate 13 .

[0040] It should be noted that the insulating cover 21 can be fixedly mounted on the top plate 13 by using bolts.

[0041] A sealing assembly 3 is provided on the isolation cover 21. The sealing assembly 3 includes two sets of seals. Each set of seals includes a sealing strip 1 31 and a sealing strip 2 32. The two sets of seals are arranged around the circumference of the top plate 13 to seal the gap between the top plate 13 and the isolation cover 21.

[0042] It should be noted that the sealing strip 1 31 and the sealing strip 2 32 are both made of insulating materials, such as rubber or silicone, which is a mature technology well known to those skilled in the art and will not be described in detail in this embodiment.

[0043] A filling strip 33 is provided on one side of the sealing strip 1 31 and the sealing strip 2 32 close to the top plate 13 . A slot 34 is provided on the filling strip 33 on the sealing strip 2 32 . The slot 34 is adapted to fit the sealing strip 1 31 .

[0044] It should be noted that the two sets of sealing members will be connected end to end after assembly, thereby completely sealing any gap that may exist between the isolation cover 21 and the top plate 13 .

[0045] A sealing groove 16 is formed on the circumferential side of the top plate 13 , and the filling strip 33 is adapted to the sealing groove 16 .

[0046] It should be noted that the cooperation between the sealing groove 16 and the filling strip 33 can effectively improve the sealing effect and the installation stability of the seal.

[0047] A second sealing groove 23 is formed on the top of the isolation cover 21 , and the first sealing strip 31 and the second sealing strip 32 are both adapted to the second sealing groove 23 .

[0048] It should be noted that the sealing groove 23 is similar to the sealing groove 16 and can effectively improve the sealing effect and the installation stability of the seal. A groove is provided at the bottom of one side of the connecting plate 22 close to the top plate 13 , and the groove is adapted to fit the sealing member.

[0049] It should be noted that, by providing the groove, the seal can be replaced without disassembling the isolation cover 21 , so that the seal can be easily replaced when it ages due to long-term use.

[0050] In this embodiment, the implementation scenario is specifically as follows: by setting up an isolation mechanism 2, the cutting fluid can be diverted to the outside of the isolation cover 21 and then discharged when using the machine tool for processing, directly isolating the workpiece waste and cutting fluid from the insulating plate 12 and the base plate 11, avoiding the adhesion of a conductive film layer on the outer surface of the base plate 11 and the insulating plate 12, thereby effectively avoiding damage to the tool.

[0051] The above-described embodiments merely illustrate several implementations of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that a person skilled in the art would be able to make numerous variations and improvements without departing from the spirit of the present invention, and all such variations and improvements fall within the scope of protection of the present invention.
