Description

Technical Field

[0001] This utility model relates to the field of grinding equipment technology, and more specifically to a carbon crucible grinding device. Background Technology

[0002] In the production of carbon-carbon composite products, the carbon-carbon crucible side is a key component, and its surface finish directly affects the product's performance and lifespan. Traditional polishing processes mainly rely on the following two methods:

[0003] One method involves manual sanding with hand-held sandpaper: the operator must manually hold the sides of the crucible and repeatedly rub to complete the surface treatment. This method has significant drawbacks:

[0004] Inefficient: Manual operation is time-consuming and labor-intensive, making it difficult to meet the needs of mass production;

[0005] Unstable quality: Uneven manual force application can easily lead to differences in surface roughness, resulting in product inconsistency;

[0006] Another method involves attaching sandpaper to the lathe tool arm for polishing: This involves fixing sandpaper to the lathe tool arm and using the lathe's rotation to move the sandpaper. However, this method also has its drawbacks:

[0007] Equipment occupancy issue: The lathe needs to be used for grinding operations throughout the entire process, and cannot perform other processing tasks at the same time, resulting in low equipment utilization.

[0008] Poor adaptability: The rigid structure of the lathe tool arm is difficult to adapt to crucibles of different sizes, and the adjustment is time-consuming and lacks precision.

[0009] Therefore, how to provide a grinding device that can be adapted to crucibles of different sizes and improve grinding efficiency is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0010] In view of this, the present invention provides a carbon crucible side grinding device, which aims to solve the above-mentioned technical problems.

[0011] To achieve the above objectives, the present invention adopts the following technical solution:

[0012] A carbon crucible side polishing device, comprising:

[0013] The frame body; a bearing plate is installed on the bottom plate surface of the frame body;

[0014] Adjustable clamping mechanism; the adjustable clamping mechanism includes a first transmission part and four clamping members. The first transmission part is mounted on the frame body. The four clamping members are arranged symmetrically in pairs on the first transmission part and are located around the bearing plate. The four clamping members move relative to each other under the drive of the first transmission part to achieve clamping.

[0015] The grinding assembly includes a second transmission part installed on the top of the frame body and a rotating disk connected to the second transmission part. Two symmetrically arranged inner wall grinding strips are slidably connected to the top surface of the rotating disk. The second transmission part can drive the rotating disk to move up and down and can drive the rotating disk to drive the inner wall grinding strips to move in a circular motion to achieve grinding of the inner wall of the crucible side to be ground.

[0016] Through the above technical solution, the carbon crucible side grinding device provided by this utility model, through the cooperation of the frame body, the bearing plate, the adjustable clamping mechanism and the grinding components, realizes the automated grinding of the inner wall of the carbon crucible side, solves the technical problems of low efficiency and instability of manual grinding, and significantly improves grinding efficiency and consistency; the four rectangular clamping parts can stably clamp the carbon crucible side, and under the drive of the first transmission part, they can also be adjusted according to the carbon crucible side of different sizes and achieve stable clamping, so that the device can be adapted to carbon crucible side of different sizes and improve the versatility of the equipment; the two symmetrically arranged inner wall grinding strips can be slidably connected to the top surface of the rotating plate, and their length extending to the outside of the rotating plate can be adjusted according to the workpiece with different inner diameters so that the inner wall grinding strips fit the inner wall of the workpiece.

[0017] Preferably, in the above-mentioned carbon crucible side grinding device, the first transmission part includes a first transmission rod, which is rotatably connected to the frame body. The first transmission rod has opposite threads on its arm, and first sliders are threaded to both sides of its arm. A second transmission rod and a third transmission rod, arranged perpendicular to the first transmission rod, are rotatably connected to the two first sliders respectively. The arms of the second and third transmission rods both have opposite threads, and second sliders are threaded to both sides of their arms. The clamping member is installed on the second slider. The opposite thread design on both sides of the first transmission rod, combined with the symmetrical drive of the second and third transmission rods, enables precise, synchronous, and multi-directional relative movement control of the four clamping members. This allows for flexible clamping operations adapted to carbon crucible sides of different sizes and shapes, effectively ensuring the stability and accuracy of clamping and meeting diverse grinding needs.

[0018] Preferably, in the above-mentioned carbon crucible grinding device, grooves are provided on the two bottom edges of the frame body parallel to the first transmission rod. A first sliding seat and a second sliding seat are slidably connected in the two grooves, respectively. The top of the first sliding seat is fixedly connected to the bottom wall of the first slider, and a support block is fixedly attached to the top of the second sliding seat. The two ends of the second transmission rod and the third transmission rod are rotatably connected to the first slider and the support block, respectively. The grooves and sliding seats ensure a stable connection and support between the first slider and related transmission rods and the sliding seats, ensuring the smooth movement of each transmission rod and clamping component during clamping. This avoids positional shift or shaking of the clamping components due to structural instability, thereby ensuring the accurate implementation of the grinding process and improving the reliability and durability of the entire device.

[0019] Preferably, in the above-mentioned carbon crucible side grinding device, the first transmission rod, the second transmission rod, and the third transmission rod are each driven by a first motor. The first transmission part also includes an auxiliary rod. The second slider has a through hole, through which the auxiliary rod passes, and its two ends are fixed between the support block and the first slider. By using the first motor to drive the first transmission rod, the second transmission rod, and the third transmission rod respectively, the transmission process is automated and precisely controlled, improving the efficiency and stability of the clamping operation. The auxiliary rod constrains the movement direction of the second slider, ensuring linear movement of the clamping component and improving positioning accuracy.

[0020] Preferably, in the above-mentioned carbon crucible side grinding device, a plurality of spaced friction bushings are fixed on the outer wall of the clamping member along its axial direction. The friction bushings increase the contact friction between the clamping member and the crucible side, preventing the workpiece from sliding during grinding; the spaced friction bushings disperse the pressure, avoiding local stress concentration that could lead to workpiece deformation.

[0021] Preferably, in the above-mentioned carbon crucible grinding device, the second transmission unit includes a second motor fixed to the side wall of the frame body, and a pulley assembly driven by the second motor. The pulley assembly is mounted on the top of the frame body via a bracket and is located above the rotating disk. A telescopic cylinder is fixed to the bottom surface of the driven wheel of the pulley assembly, and the telescopic end of the telescopic cylinder is fixedly connected to the top surface of the rotating disk. The pulley assembly transmits power more smoothly, reducing the impact of vibration on grinding accuracy; the telescopic cylinder enables precise lifting and lowering of the rotating disk, and combined with the rotational drive of the pulley, forms a composite motion mode, covering a more comprehensive grinding range.

[0022] Preferably, in the above-mentioned carbon crucible side grinding device, two slide rails extending towards the edge of the rotating disk are symmetrically fixed on the top surface of the rotating disk and on both sides of the telescopic cylinder. A third slider is slidably connected to each slide rail, and a connecting rod parallel to the slide rail is fixed to the third slider. Two inner wall grinding strips are respectively fixed to the two connecting rods, with the grinding end of the inner wall grinding strip located below the rotating disk. The slide rails and third sliders allow for radial adjustment of the inner wall grinding strips to adapt to crucible sides of different inner diameters; the connecting rods fix the grinding strips, ensuring angle stability during grinding and improving the consistency of the inner wall surface processing; the symmetrical structural design also helps to ensure the stability and uniformity of the grinding process, further improving the quality and efficiency of inner wall grinding.

[0023] Preferably, in the above-mentioned carbon crucible side grinding device, the middle sections of the second and third transmission rods are both smooth rod sections, and mounting blocks are sleeved on the outer sides of the smooth rod sections. An outer wall grinding strip is fixed on the mounting block. Two diagonally arranged clamping members are rotatably connected to the second slider and, driven by the rotating assembly, drive the workpiece to be ground to rotate, cooperating with the outer wall grinding strip to achieve outer wall grinding of the workpiece. The outer wall grinding strip cooperates with the rotating clamping members to achieve outer wall grinding. The bearing-fixed mounting block reduces the interference of transmission rod vibration on the outer wall grinding, ensuring the quality of outer wall grinding.

[0024] Preferably, in the above-mentioned carbon crucible side grinding device, the rotating component includes a third motor, a first gear, and a second gear; the third motor is fixed on the second slider, the axle of the first gear is fixedly connected to the power output shaft of the third motor, and the second gear is sleeved on the outside of the clamping member and meshes with the first gear. The gear transmission structure is compact and the power transmission is efficient, ensuring smooth rotation of the clamping member; through precise control of the motor, the stability and accuracy of the rotation speed can be guaranteed, thereby making the relative movement between the outer wall grinding strip and the outer wall of the crucible more stable, effectively improving the quality and effect of outer wall grinding, and ensuring the uniformity and consistency of grinding.

[0025] Preferably, in the above-mentioned carbon crucible side grinding device, the support plate is rotatably connected to the base plate. This rotatable connection of the support plate reduces the resistance to rotation of the workpiece being ground, decreases energy loss and equipment wear, improves the driving efficiency of the rotating components, and ensures a stable and uniform grinding process on the outer wall.

[0026] As can be seen from the above technical solution, compared with the prior art, the present invention discloses a carbon crucible side grinding device, which has the following beneficial effects:

[0027] 1. The adjustable clamping mechanism of this utility model can flexibly adjust the position of the clamping parts to adapt to carbon crucible sides of different sizes and shapes.

[0028] 2. The rotating disc of this utility model drives the inner wall grinding strip through the lifting and circumferential motion of the second transmission part. Combined with the setting of the slide rail and the third slider, it can make the inner wall grinding strip fit with the inner wall of carbon crucibles of different inner diameters, thereby improving the grinding quality. It can be applied to carbon crucibles of different heights.

[0029] 3. The diagonally arranged clamping components of this utility model drive the workpiece to be polished to rotate under the drive of the rotating assembly, and contact the fixed outer wall polishing strip to achieve outer wall polishing.

[0030] 4. This utility model achieves grinding of the inner and outer walls by independently / time-sharing control of the rotating disk and rotating components, avoiding structural interference and improving efficiency. By combining the circumferential motion of the rotating disk, the lifting and lowering adjustment of the telescopic cylinder, and the rotation of the workpiece being ground under the drive of the rotating components, the grinding action is evenly and comprehensively applied to the inner and outer walls of the crucible, avoiding grinding omissions or uneven grinding, thereby significantly improving the grinding quality and making the surface of the ground crucible have higher flatness and smoothness, meeting the production requirements of high-quality crucible.
