Description

Technical Field

[0001] The utility model belongs to the technical field of graphite component processing, in particular to a special tool bar for processing graphite damping and anti-vibration. Background Art

[0002] Graphite is a carbon-containing inorganic material with unique physical and chemical properties. Its structure and properties make it widely used in many fields, including graphite parts produced using graphite as raw material.

[0003] When processing graphite parts, due to the brittleness of graphite, ordinary metal processing tools are not suitable, so special tools, such as diamond tools, can only be used; however, the existing tool heads need to be welded by the staff themselves, which is cumbersome and not only in contact with high temperatures, but also has a high risk factor. When installing the tool rod, it is also necessary to repeatedly align the center height, which takes a long time to prepare and cannot be standardized. For this reason, we proposed a special tool rod for machining graphite damping and anti-vibration to solve the above problems. Utility Model Content

[0004] The purpose of the utility model is to provide a special tool bar for machining graphite damping and anti-vibration, so as to solve the problems existing in the background technology.

[0005] In order to achieve the above technical purpose, the technical solution adopted by the utility model is as follows:

[0006] A special tool bar for machining graphite damping and anti-vibration includes a T-shaped tool seat, a cylindrical tool bar is installed on the front side of the T-shaped tool seat, a clamping groove is opened in the lower middle part of the front end of the cylindrical tool bar, a tool is clamped in the clamping groove, an expansion groove is opened in the middle of the rear wall of the clamping groove, a mounting plane is opened in the upper part of the front end of the cylindrical tool bar, and a fixing hole that passes through the expansion groove and the cylindrical tool bar is opened at the upper end of the mounting plane.

[0007] Furthermore, a positioning plane is provided on the upper end of the cylindrical tool rod.

[0008] Furthermore, an arc surface is provided between the installation plane and the positioning plane.

[0009] Furthermore, the tool comprises a white steel mounting seat and a diamond blade. A mounting groove is provided on the front side of the upper end of the white steel mounting seat, and the diamond blade is installed inside the mounting groove.

[0010] Furthermore, a circular groove is provided in the middle of the front end of the T-shaped tool holder, the cylindrical tool rod is arranged inside the circular groove, a through groove connected to the circular groove is provided in the middle of the left end of the T-shaped tool holder, and a plurality of evenly arranged threaded holes are provided on the left side of the upper end of the T-shaped tool holder, and each of the threaded holes passes through the through groove and extends into the interior of the T-shaped tool holder.

[0011] The beneficial effects of the utility model are:

[0012] 1) By inserting the bolt into the threaded hole, the T-shaped tool holder can clamp and fix the cylindrical tool arbor, thereby preventing vibration when using the cylindrical tool arbor and affecting the processing of graphite parts.

[0013] 2) By detecting and adjusting the positioning plane, the cylindrical tool arbor can be installed flatly, thereby indirectly making the cutting point of the installed tool and the center height on the CNC lathe on the same horizontal plane, thereby improving the installation efficiency of the installer.

[0014] 3) The combination of the stainless steel mounting seat and the diamond blade not only increases the thickness of the tool, strengthens the tool strength, and enables the tool to be used for a longer time, but also widens the tool cutting area and improves the scope of application of the tool.

[0023] In order to enable those skilled in the art to better understand the present invention, the technical solution of the present invention is further described below in conjunction with the accompanying drawings and embodiments.

[0024] Embodiment 1:

[0025] like Figure 1-Figure 2 As shown, a special tool bar for machining graphite damping and anti-vibration includes a T-shaped tool seat 100, a cylindrical tool bar 101 is installed on the front side of the T-shaped tool seat 100, a clamping groove 102 is opened in the lower middle part of the front end of the cylindrical tool bar 101, a tool 103 is clamped inside the clamping groove 102, an expansion groove 104 is opened in the middle of the rear wall of the clamping groove 102, a mounting plane 105 is opened on the upper part of the front end of the cylindrical tool bar 101, and a fixing hole 106 that passes through the expansion groove 104 and the cylindrical tool bar 101 is opened on the upper end of the mounting plane 105.

[0026] The T-shaped tool holder 100 can be installed with a cylindrical tool rod 101, and the expansion groove 104 can expand the clamping groove 102 to facilitate the opening or closing of the clamping groove 102. The clamping groove 102 can clamp the tool 103, and the tool 103 can process the graphite parts to be processed. The fixing hole 106 can be threaded with a bolt to tighten the clamping groove 102 and the expansion groove 104, thereby achieving the purpose of clamping and fixing the tool 103. The mounting plane 105 can accommodate the bolt head after the bolt is fixed to prevent the bolt head from contacting the graphite parts to be processed and affecting the processing of the graphite parts.

[0027] The standard center heights of existing CNC lathes are generally 20mm, 25mm and 32mm. In this embodiment, the center height of 20mm is taken as an example: the diameter of the cylindrical tool rod 101 is 32mm, the upper wall of the clamping groove 102 coincides with the center horizontal plane of the cylindrical tool rod 101, the opening of the clamping groove 102 is 5mm, and the distance between the lower wall of the protrusion at the right end of the T-shaped tool holder 100 and the center horizontal plane of the cylindrical tool rod 101 is 20mm. In this way, when the staff installs the tool 103, it will be more convenient to calibrate the center height, so that the cutting surface of the tool 103 coincides with the center plane of the graphite part to be processed, thereby facilitating the direct processing of the graphite part.

[0028] Before processing graphite parts: first install the T-shaped tool holder 100 on the CNC lathe, then install the cylindrical tool rod 101 on the T-shaped tool holder 100, and then insert the tool 103 into the clamping groove 102, insert it into the fixing hole 106 through the bolt thread connection, and rely on squeezing the expansion groove 104 and the clamping groove 102 to clamp and fix the tool 103, thereby facilitating the subsequent processing of graphite parts.

[0029] In this embodiment, the expansion groove 104 and the clamping groove 102 can be indirectly tightened through the threaded connection between the bolt and the fixing hole 106, so that the tool placed inside the clamping groove 102 can be clamped and fixed, making the installation and replacement of the tool 103 more convenient and quick.

[0030] Embodiment 2:

[0031] Based on the first embodiment, the components on the tool bar and other parts are further described. Figure 1, Figure 3 and Figure 4 As shown, a positioning plane 200 is formed at the upper end of the cylindrical tool rod 101 .

[0032] An arc surface 201 is provided between the installation plane 105 and the positioning plane 200 .

[0033] The tool 103 includes a white steel mounting seat 202 and a diamond blade 203. A mounting groove is provided on the front side of the upper end of the white steel mounting seat 202, and the diamond blade 203 is installed inside the mounting groove.

[0034] A circular groove is provided in the middle of the front end of the T-shaped tool holder 100, and the cylindrical tool rod 101 is arranged inside the circular groove. A through groove 204 connected to the circular groove is provided in the middle of the left end of the T-shaped tool holder 100, and a plurality of evenly arranged threaded holes 205 are provided on the left side of the upper end of the T-shaped tool holder 100, and each threaded hole 205 passes through the through groove 204 and extends into the interior of the T-shaped tool holder 100.

[0035] In this embodiment, when installing the cylindrical tool rod 101 on the T-shaped tool holder 100, the staff can detect whether the installed cylindrical tool rod 101 is horizontal through the positioning plane 200. This is conducive to the cutting surface of the subsequently installed tool 103 and the center height being on the same horizontal plane, reducing the time for the staff to locate the center height and improving the installation efficiency of the staff.

[0036] During processing, the arc surface 201 can well withstand the squeezing force of the graphite part on the cylindrical tool rod 101 during processing, preventing the junction between the installation plane 105 and the positioning plane 200 from being broken, thereby affecting the processing of the graphite part.

[0037] The white steel mounting seat 202 has certain hardness and toughness, and can be used with the diamond blade 203 to increase the thickness of the tool 103, which can not only increase the strength of the tool 103 and extend its service life, but also increase the cutting area and improve the scope of application.

[0038] The through groove 204 can make the circular groove contract and expand, so that the cylindrical tool rod 101 can be easily inserted into the circular groove, and then the cylindrical tool rod 101 can be clamped and fixed by inserting the bolt into the threaded hole 205, so as to prevent the cylindrical tool rod 101 from vibrating during the processing of graphite parts, thereby affecting the processing of graphite parts.

[0039] When the ratio of the length of one end of the cylindrical tool rod 101 extending out of the circular groove to the diameter of the cylindrical tool rod 101 is 3:1, the cylindrical tool rod 101 can reach the maximum seismic resistance limit, and can also prevent the cylindrical tool rod 101 from vibrating and affecting the processing of graphite parts.
