Description

Technical Field

[0001] This invention relates to the field of isostatic graphite material technology, and in particular to an isostatic graphite material surface treatment device and method. Background Technology

[0002] The apparatus for surface treatment of isostatically pressed graphite materials is chemical vapor deposition (CVD). CVD is a method that uses gaseous precursors to undergo chemical reactions on the graphite surface, thereby forming new materials or improving surface properties.

[0003] During the preparation of isostatic graphite, various impurities will be mixed on the surface, and burrs or protrusions will appear on the outer layer of the finished product. Therefore, it is necessary to remove the burrs on the surface. Existing processing methods are inconvenient for fixing isostatic graphite materials, and the degree of scraping by the scraper is also inconvenient to adjust. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing technologies, such as the inconvenience of fixing isostatic graphite materials and the difficulty in adjusting the degree of scraping by the scraper. Therefore, this invention proposes a surface treatment device and method for isostatic graphite materials.

[0005] To address the problems existing in the prior art, the present invention adopts the following technical solution:

[0006] An isostatic pressing graphite material surface treatment device includes a base plate, four evenly distributed support legs fixed on the bottom surface of the base plate, a circular through hole on the right side of the top surface of the base plate, a rotating fixed plate engaged inside the circular through hole, and a loading plate placed on the top surface of the fixed plate.

[0007] Three circular driven shafts are inserted into the top surface of the fixed disk. Each driven shaft has a driven swing arm fixed at its top end. Each driven swing arm has a rotatably connected axle inserted into its outer end. Each axle has a concentrically fixed limiting wheel fitted at its top end. The three limiting wheels are circular and abut against the outer surface of the loading disk.

[0008] A pair of T-shaped seats arranged side by side are fixed on the left side of the top surface of the base plate. An L-shaped swing arm is arranged laterally and movably hinged between the tops of the pair of T-shaped seats. A scraper is installed at the right end of the L-shaped swing arm, and the scraper extends to the upper left of the top surface of the tray.

[0009] Preferably, a first through hole is provided on the left side of the bottom surface of the base plate, and a first motor with the output end facing downward is fixed inside the first through hole. A small-diameter pulley is fitted on the end of the motor shaft of the first motor.

[0010] Preferably, a large-diameter pulley is concentrically fixed to the bottom of the outer ring surface of the fixed disk, and the small-diameter pulley is synchronously connected to the large-diameter pulley through a drive belt.

[0011] Preferably, the top surface of the fixed plate has three positioning grooves, which are staggered with the three driven shafts. The bottom surface of the loading plate has three positioning rods, and the bottom end of each positioning rod is inserted into the corresponding positioning groove.

[0012] Preferably, a second through hole is provided in the middle of the fixed disk, and a second motor with the output end facing upward is fixed inside the second through hole, and a drive gear is sleeved on the end of the motor shaft of the second motor.

[0013] Preferably, each driven shaft is fitted with a concentrically fixed driven gear, and the drive gear meshes with the three driven gears.

[0014] Preferably, each of the T-shaped seats is provided with a rotatably connected linkage shaft at its top end, and a linkage swing arm is fixed at the front end of each linkage shaft. A pair of linkage swing arms are respectively hinged to the left end and the middle of the back of the L-shaped swing arm.

[0015] Preferably, each of the linkage shafts is fitted with a concentrically fixed linkage pulley in the middle, and a linkage belt for synchronous transmission is fitted between a pair of linkage pulleys. A third motor is fixed on the top of the back of one of the T-shaped seats, and the end of the motor shaft of the third motor is coaxially connected to the linkage shaft on the corresponding side.

[0016] Preferably, a U-shaped bracket is fixed to the right end of the L-shaped swing arm, and a flat protrusion is fixed to the center of the top surface of the scraper. The top of the flat protrusion is engaged in the U-shaped bracket, and the U-shaped bracket is locked to the flat protrusion by a pair of bolts and nuts.

[0017] This invention also proposes a surface treatment method for isostatically pressed graphite materials, comprising the following steps:

[0018] Step 1: Place the solidified isostatic graphite material in the loading tray and place the loading tray on the fixed plate so that the positioning rods are all inserted into the positioning slots. Start the second motor, which drives the drive gear to rotate synchronously. The drive gear meshes and drives the driven gear, driven shaft and driven swing arm to rotate, so that the three limit wheels abut against the outer surface of the loading tray.

[0019] Step 2: Start the first motor. The motor shaft of the first motor drives the small-diameter pulley to rotate synchronously. The small-diameter pulley drives the large-diameter pulley, the fixed plate and the loading plate to rotate synchronously through the drive belt.

[0020] Step 3: Start the third motor. The motor shaft of the third motor drives the linkage shaft to rotate synchronously. Through the transmission action of the linkage belt and a pair of linkage pulleys, it drives the other linkage shaft to rotate synchronously.

[0021] This causes a pair of linked swing arms to swing synchronously, which in turn causes the L-shaped swing arm, U-shaped bracket, and scraper to slowly fall downwards. When the scraper contacts the surface of the isostatic graphite material, it performs a scraping treatment on the surface.

[0022] Compared with the prior art, the beneficial effects of the present invention are:

[0023] 1. In this invention, the three driven swing arms are driven by the second motor, so that the three limit wheels abut against the outer surface of the loading plate, forming a fixing effect on the isostatic graphite material and ensuring its stability during the wall scraping process.

[0024] 2. In this invention, a pair of linked swing arms and an L-shaped swing arm are driven by a third motor to drive the scraper to fall slowly downward and scrape the surface of the isostatic graphite material, resulting in better scraping effect and more uniform treatment.

[0025] In summary, this invention is simple and quick to use, highly automated, efficient in processing, safe and reliable in use, and produces consistent processing results. Attached Figure Description

[0033] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0034] Example 1: This example provides a surface treatment device for isostatically pressed graphite materials. See [link to example]. Figure 1-5 Specifically, it includes a base plate 1, with four evenly distributed support legs fixed on the bottom surface of the base plate 1. A circular through hole is opened on the right side of the top surface of the base plate 1, and a rotating fixed plate 11 is engaged inside the circular through hole. A loading plate 12 is placed on the top surface of the fixed plate 11.

[0035] Three circularly arranged driven shafts 22 are inserted on the top surface of the fixed plate 11. Each driven shaft 22 is fixed with a driven swing arm 24 at its top end. Each driven swing arm 24 is inserted with a rotatably connected axle 25 at its outer end. Each axle 25 is fitted with a concentrically fixed limiting wheel 26 at its top end. The three limiting wheels 26 are circular and abut against the outer surface of the loading plate 12.

[0036] Three positioning slots are provided on the top surface of the fixed plate 11. The three positioning slots are staggered with the three driven shafts 22. Three positioning rods are fixed on the bottom surface of the loading plate 12. The bottom end of each positioning rod is inserted into the corresponding positioning slot.

[0037] A pair of T-shaped seats 3 arranged side by side are fixed on the top left side of the base plate 1. An L-shaped swing arm 33 is arranged horizontally and movably hinged between the tops of the pair of T-shaped seats 3. A scraper 35 is installed at the right end of the L-shaped swing arm 33, and the scraper 35 extends to the upper left of the top surface of the tray 12.

[0038] In the specific implementation process, such as Figure 2 and Figure 3As shown, a first through hole is provided on the left side of the bottom surface of the base plate 1. A first motor 13 with the output end facing downward is fixed inside the first through hole. A small-diameter pulley is concentrically fixed to the end of the motor shaft of the first motor 13. A large-diameter pulley is concentrically fixed to the bottom of the outer ring surface of the fixed disk 11. The small-diameter pulley is synchronously connected to the large-diameter pulley through the drive belt 14. The motor shaft of the first motor 13 drives the small-diameter pulley to rotate synchronously. The small-diameter pulley drives the large-diameter pulley, the fixed disk 11 and the loading disk 12 to rotate synchronously through the drive belt 14.

[0039] It should be noted that: In this embodiment, a second through hole is provided in the middle of the fixed disk 11, and a second motor 2 with the output end facing upward is fixed inside the second through hole. A drive gear 21 is concentrically fixed at the end of the motor shaft of the second motor 2; a driven gear 23 is concentrically fixed on each driven shaft 22, and the drive gear 21 meshes with the three driven gears 23; the second motor 2 drives the drive gear 21 to rotate synchronously, and the drive gear 21 meshes with and drives the driven gear 23, the driven shaft 22 and the driven swing arm 24 to rotate, so that the three limit wheels 26 abut against the outer surface of the loading disk 12.

[0040] Example 2: Based on Example 1, this example also includes:

[0041] In the specific implementation process, such as Figure 3 and Figure 5 As shown, each T-shaped seat 3 has a rotatably connected linkage shaft 31 inserted at its top end. Each linkage shaft 31 has a linkage swing arm 32 fixed at its front end. A pair of linkage swing arms 32 are respectively hinged to the left end and the middle of the back of the L-shaped swing arm 33. This causes the pair of linkage swing arms 32 to swing synchronously, and then causes the L-shaped swing arm 33, U-shaped seat 34 and scraper 35 to fall slowly downwards. The scraper 35 scrapes the surface of the isostatic graphite material.

[0042] Each linkage shaft 31 is fitted with a concentrically fixed linkage pulley in the middle, and a linkage belt 36 is fitted between a pair of linkage pulleys for synchronous transmission. A third motor 37 is fixed on the top of the back of one of the T-shaped seats 3. The end of the motor shaft of the third motor 37 is coaxially connected to the linkage shaft 31 on the corresponding side. The motor shaft of the third motor 37 drives the linkage shaft 31 to rotate synchronously. Through the transmission action of the linkage belt 36 and a pair of linkage pulleys, it drives the other linkage shaft 31 to rotate synchronously.

[0043] The right end of the L-shaped swing arm 33 is fixed with a U-shaped bracket 34, and the top surface of the scraper 35 is fixed with a flat protrusion. The top of the flat protrusion is engaged in the U-shaped bracket 34. The U-shaped bracket 34 is locked to the flat protrusion by a pair of bolts and nuts. The scraper 35 can be disassembled and replaced through the U-shaped bracket 34.

[0044] Specifically, the working principle and operation method of this invention are as follows:

[0045] Step 1: Place solidified isostatic graphite material in the loading tray 12 and place the loading tray 12 on the fixed tray 11 so that the positioning rods are all inserted into the positioning slots. Start the second motor 2. The second motor 2 drives the drive gear 21 to rotate synchronously. The drive gear 21 meshes and drives the driven gear 23, driven shaft 22 and driven swing arm 24 to rotate so that the three limit wheels 26 abut against the outer surface of the loading tray 12.

[0046] Step 2: Start the first motor 13. The motor shaft of the first motor 13 drives the small diameter pulley to rotate synchronously. The small diameter pulley drives the large diameter pulley, the fixed disk 11 and the loading disk 12 to rotate synchronously through the drive belt 14.

[0047] Step 3: Start the third motor 37. The motor shaft of the third motor 37 drives the linkage shaft 31 to rotate synchronously. Through the transmission action of the linkage belt 36 and a pair of linkage pulleys, it drives the other linkage shaft 31 to rotate synchronously.

[0048] This causes a pair of linked swing arms 32 to swing synchronously, which in turn causes the L-shaped swing arm 33, U-shaped bracket 34, and scraper 35 to slowly fall downwards. When the scraper 35 contacts the surface of the isostatic graphite material, it performs a scraping treatment on the surface.

[0049] This invention is simple and quick to use, highly automated, efficient, safe and reliable, and produces consistent processing results.
