Description

Technical Field

[0001] This utility model relates to the technical field of graphite product processing equipment, and specifically discloses a chamfering device for processing graphite crucibles. Background Technology

[0002] Graphite crucibles are widely used in metallurgy, chemical industry, building materials and other industrial fields due to their excellent properties such as high temperature resistance, good thermal conductivity and strong chemical stability. During the production and processing of graphite crucibles, to prevent sharp edges from scratching operators or affecting the precision of their fit with other equipment, the edges are usually chamfered.

[0003] Currently, traditional graphite crucible chamfering is mostly done manually using hand tools or general-purpose machine tools. Manual chamfering is not only labor-intensive and inefficient, but also makes it difficult to guarantee chamfering accuracy, easily leading to crucible edge breakage due to uneven force. While general-purpose machine tools can improve accuracy to some extent, the curved shape of graphite crucibles makes clamping and fixing difficult, and adjusting the chamfering angle and position is inconvenient, making it difficult to adapt to the processing of graphite crucibles of different specifications and chamfering requirements. Furthermore, graphite is a brittle material, and improper force control during clamping can easily cause crucible breakage, affecting product yield. Therefore, there is an urgent need for a chamfering device specifically designed for the characteristics of graphite crucibles, featuring precise clamping, multi-angle adjustment, and high efficiency and stability, to overcome the shortcomings of existing processing methods.

[0023] The present invention will be further described below with reference to the accompanying drawings and specific embodiments to aid in understanding its content. Unless otherwise specified, the methods used in this invention are conventional methods; the raw materials and apparatus used, unless otherwise specified, are conventional commercially available products.

[0024] Please see Figure 1-4 A chamfering device for processing graphite crucibles includes a base 1, a clamping mechanism 2 disposed on the base 1, and a chamfering mechanism 3, with the chamfering mechanism 3 located behind the clamping mechanism 2. The clamping mechanism 2 includes a rotating seat 4 rotatably disposed on the top of the base 1, two clamping arms 5 symmetrically disposed above the rotating seat 4, and a horizontal adjustment component that drives the two clamping arms 5 to move synchronously towards or away from each other along the radial direction of the rotating seat 4. An arc-shaped clamping block 6 adapted to the outer wall of the graphite crucible is detachably connected to the inner side of the clamping arm 5, and an elastic buffer layer 7 is embedded on the inner surface of the arc-shaped clamping block 6. A circular groove 8 for accommodating the rotating seat 4 is provided on the top of the base 1, and a bidirectional thrust ball bearing 9 is provided between the bottom of the rotating seat 4 and the circular groove 8. A rotary drive mechanism for driving the rotating seat 4 to rotate is provided at the bottom of the base 1.

[0025] The chamfering mechanism 3 includes a column 10 fixedly mounted on the base 1, a lifting slide 11 slidably mounted along the height direction of the column 10, a transverse slide 12 slidably mounted at the bottom of the lifting slide 11, and a tool assembly 14 mounted on the transverse slide 12 via an angle adjustment mechanism 13. The angle adjustment mechanism 13 includes an angle seat 15 fixedly mounted at the bottom of the transverse slide 12, and a rotating shaft 16 passing through and rotatably connected to the angle seat 15. The upper end of the rotating shaft 16 is located inside the angle seat 15 and a worm gear 17 is coaxially fixed thereon. The angle seat 15 is provided with a worm 18 meshing with the worm gear 17. One end of the worm 18 extends to the outside of the angle seat 15 and is fixedly connected to a rotating handle 19. An angle scale 20 is provided on the outer periphery of the angle seat 15, and a positioning pointer 21 pointing to the angle scale 20 is fixedly mounted on the rotating shaft 16. The tool assembly 14 includes a tool holder 22 fixedly connected to the lower end of the rotating shaft 16, a chamfering tool 23 mounted on the tool holder 22, and a tool motor 24 that drives the chamfering tool 23 to rotate.

[0026] In this embodiment: the graphite crucible to be processed is placed on the rotating base 4. The linear actuator 27 in the horizontal adjustment assembly slides along the radial guide rail 25 via the drive slider 26, driving the two clamping arms 5 to move synchronously towards each other, so that the arc-shaped clamping block 6 fits against the outer wall of the crucible. The elastic buffer layer 7 on the inner surface of the clamping block compensates for the slight unevenness of the outer wall of the crucible through deformation, which increases the friction to prevent slippage and avoids damage to the graphite material caused by rigid contact, thus achieving a stable coaxial clamping of the crucible. The rotary drive mechanism at the bottom of the base 1 (after the drive motor 29 is reduced by the reducer 30) transmits power to the rotating base 4. With the support of the bidirectional thrust ball bearing 9, the rotating base 4 drives the crucible to rotate smoothly in the circular groove 8, providing the basic motion for uniform chamfering in the circumferential direction. At the same time, the chamfering mechanism 3 realizes the multi-dimensional adjustment and cutting action of the tool: the column 10 serves as the supporting base, and the vertical drive assembly pushes the lifting slide 11 through the lifting actuator 33. The tool assembly 14 is raised and lowered along the vertical guide rail 31 (with guide block 32), adjusting its height to suit the processing position of crucibles of different heights. The horizontal slide 12 moves along the horizontal guide rail 34 of the lifting slide 11 under the drive of the horizontal drive assembly, controlling the horizontal distance between the chamfering tool 23 and the crucible, and precisely adjusting the chamfering depth. In the angle adjustment mechanism 13, the operator rotates the rotary handle 19 to drive the worm gear 18 to rotate. Through the meshing transmission between the worm gear 18 and the worm wheel 17, the rotating shaft 16 is driven to rotate, causing the tool holder 22 and the chamfering tool 23 to achieve angle deflection. The angle scale 20 on the outer periphery of the angle seat 15 cooperates with the positioning pointer 21 on the rotating shaft 16 to ensure precise control of the chamfering angle. The self-locking characteristics of the worm wheel 17 and the worm gear 18 can maintain angle stability. When the tool position and angle are adjusted to the correct position, the tool motor 24 drives the chamfering tool 23 to rotate at high speed, forming a relative cutting motion with the rotating crucible to complete the chamfering processing at the specified angle and depth.

[0027] It should be noted that the linear actuator 27, the lifting actuator 33, and the horizontal actuator 35 are electric telescopic rods, pneumatic telescopic rods, or hydraulic telescopic rods; the transverse slide 12, the slider 26, and the guide block 32 are all dovetail-shaped.

[0028] As a technical optimization of this utility model, the horizontal adjustment component includes two radial guide rails 25 symmetrically opened on the upper surface of the rotating seat 4, a slider 26 fixed to the bottom of each clamping arm 5 and slidingly engaged with the corresponding guide rail 25, and a linear driver 27 that drives the two sliders 26 to move synchronously in opposite directions; the linear driver 27 is fixed above the rotating seat 4 through a connecting seat 28, and its telescopic end is connected to the clamping arm 5.

[0029] In this embodiment: by using the guide rail 25, slider 26, and linear driver 27, the linear driver 27 is activated to ensure that the clamping arm 5 moves stably in the radial direction, thereby achieving rapid clamping and center positioning of crucibles of different specifications, and improving clamping accuracy and operating efficiency.

[0030] As a technical optimization of this utility model, the rotary drive mechanism includes a drive motor 29 and a reducer 30 fixed to the bottom of the base 1. The output shaft of the drive motor 29 is connected to the input shaft of the reducer 30. The output shaft of the reducer 30 passes through the center of the base 1 and the bidirectional thrust ball bearing 9 and is fixedly connected to the bottom of the rotary seat 4.

[0031] In this embodiment, the drive motor 29 and reducer 30 provide stable and controllable rotational power to the rotating base 4, ensuring that the crucible rotates at a uniform speed and avoiding uneven chamfering caused by speed fluctuations.

[0032] As a technical optimization of this utility model, the lifting slide 11 slides along the column 10 through a vertical drive assembly; the vertical drive assembly includes a vertical guide rail 31 fixed on the column 10, a guide block 32 that slides with the vertical guide rail 31, and a lifting driver 33 that drives the lifting slide 11 to rise and fall; the lifting slide 11 is fixedly connected to the guide block 32, the fixed end of the lifting driver 33 is connected to the column 10, and the telescopic end is connected to the lifting slide 11.

[0033] In this embodiment: by using the vertical guide rail 31, guide block 32, and lifting driver 33, the lifting driver 33 is activated to achieve precise adjustment of the tool height, adapting to the processing requirements of crucibles of different heights and improving the versatility of the device.

[0034] As a technical optimization of this utility model, the transverse slide 12 slides along the lifting slide 11 via a horizontal drive assembly; the horizontal drive assembly includes a horizontal guide rail 34 fixed on the lifting slide 11 and adapted to the transverse slide 12, and a horizontal driver 35 that drives the transverse slide 12 to move within the horizontal guide rail 34; the horizontal driver 35 is located outside the horizontal guide rail 34, and its telescopic end is connected to the transverse slide 12.

[0035] In this embodiment: by using the horizontal guide rail 34 and the horizontal driver 35, the horizontal driver 35 is activated to achieve precise control of the horizontal feed of the tool, ensuring consistent chamfer depth and improving machining accuracy.

[0036] As a technical optimization of this utility model, the elastic buffer layer 7 is made of rubber or silicone.

[0037] In this embodiment: the elastic buffer layer 7 is made of rubber or silicone. Such materials have good elasticity and wear resistance, which can effectively buffer the clamping force, protect the graphite crucible from damage, and ensure the reliability of clamping.

[0038] Working principle and usage process of this utility model:

[0039] Place the graphite crucible to be processed in the center of the rotating seat 4. Operate the horizontal adjustment component to move the two clamping arms 5 towards each other until the elastic buffer layer 7 of the arc-shaped clamping block 6 fits against the outer wall of the crucible, thus completing the clamping and fixing. According to the chamfering position requirements, adjust the lifting slide 11 to a suitable height through the vertical drive component, and adjust the transverse slide 12 through the horizontal drive component to bring the tool closer to the workpiece. Turn the rotating handle 19 to drive the rotating shaft 16 to rotate through the worm gear 17 and worm 18. Adjust the tool to the preset chamfering angle according to the angle scale 20 and the pointer. Simultaneously start the rotating drive mechanism (driving the crucible to rotate) and the tool motor 24 (driving the chamfering tool 23 to rotate). Control the transverse slide 12 to feed slowly through the horizontal drive component to complete the chamfering cut. After processing, turn off the motor, reverse the horizontal drive component to move the tool away from the workpiece, operate the horizontal adjustment component to release the clamping arm 5, and remove the processed crucible.
