Description

Technical Field

[0001] This utility model relates to the field of workpiece processing technology, and is used for rapid positioning, clamping and heat conduction of silicon carbide furnace electrodes, and particularly to a heat conduction bracket processing fixture. Background Technology

[0002] In the processing of silicon carbide furnace electrodes, precise positioning and stable clamping of the electrodes are crucial to ensuring processing quality, directly affecting the electrode's dimensional accuracy, surface quality, and final thermal conductivity. However, current processing tooling used in the industry has many unresolved issues, severely restricting the improvement of production efficiency and processing quality.

[0003] Firstly, regarding adaptability, existing machining fixtures are mostly integrated, fixed structures. The size, spacing, and shape of their clamping components are fixed, meaning they can only be designed for electrodes of specific specifications. When there are significant differences in their lengths, existing fixtures cannot effectively clamp them, necessitating replacement with the appropriate fixture. This single adaptability forces companies to stock multiple specifications of fixtures, occupying substantial storage space and significantly increasing equipment procurement costs. Moreover, changing fixtures requires readjusting the relative positions of the lathe and the fixture, typically taking over 30 minutes each time, which drastically slows down production pace for multi-variety, small-batch production needs.

[0004] Secondly, regarding positioning accuracy, existing tooling lacks reliable positioning benchmarks and auxiliary structures. The connection between the clamping plate and the base often uses a single bolt or simple snap-fit ​​method. During installation, the clamping plate is prone to horizontal offset or vertical tilting. This positioning deviation directly results in the machining surface of the electrode being processed not being parallel to the design reference surface, leading to problems such as excessive assembly gaps and obstructed heat conduction paths in the final heat-conducting bracket. Although some tooling has positioning holes, their distribution is unreasonable, only enabling positioning in a single direction and failing to cope with multi-directional displacement caused by vibration during processing, further exacerbating the insufficient positioning accuracy problem.

[0005] Furthermore, in terms of thermal conductivity, the existing tooling design neglects the need for heat conduction. Since silicon carbide furnace electrodes need to be processed in high-temperature environments, heat needs to be dissipated promptly. In summary, the shortcomings of existing processing tooling in terms of adaptability, positioning accuracy, thermal conductivity, connection stability, and ease of operation have become bottlenecks restricting the development of the heat-conducting support processing industry. Developing a processing tooling that can adapt to various specifications of electrodes, provides precise positioning, efficient thermal conductivity, a stable structure, and convenient operation has become an urgent need in the industry. This utility model can be used for rapid positioning, clamping, and heat conduction of silicon carbide furnace electrodes, solving the problems of unstable electrode fixation and low positioning accuracy in high-temperature environments, and is suitable for mass production in crystal growth equipment.

Detailed Implementation

[0035] The following is a detailed explanation with reference to the accompanying drawings.

[0036] Example 1

[0037] This utility model provides a tooling for processing a heat-conducting bracket, such as Figures 1 to 3As shown, the device includes a base 100 and a clamping plate 200 threadedly connected to the base 100. The base 100 has at least three positioning holes 101 on its side. The clamping plate 200 has fixing holes 201 corresponding to the positioning holes 101. At least two fixing holes 201 are bolted to two of the three positioning holes 101 on the base 100 to connect the base 100 and the clamping plate 200. A clamping member 102 for fixing a tooling is provided on the vertical bottom surface of the base 100. The clamping member 102 is connected to the base 100, and at least partially located outside the base 100. The clamping member 102 is used to fix the base 100 integrally to a lathe, and the clamping member 102 and the base 100 form a position for placing the clamping plate 200. The clamping member 102 is offset from the base 100 by being partially located outside the base 100, thereby facilitating the horizontal positioning of the clamping plate 200. The staggered design of the clamping member 102 and the base 100 provides a clear horizontal positioning reference during the installation of the clamping plate 200, reducing positioning errors and ensuring the accuracy of the clamping plate 200's installation position. Simultaneously, the tight connection between the base 100 and the clamping plate 200, and the abutment between the clamping plate 200 and the clamping member 102, ensure a secure fit. Furthermore, the base 100 in this invention is provided with several positioning holes 101, which are bolted to the fixing holes 201 of the clamping plate 200. Its replaceable modular design can adapt to different electrode specifications. When the electrode specifications change, simply replacing the clamping plate 200 at the corresponding fixing hole 201 position allows for quick adaptation, significantly improving the tooling's versatility. At the same time, the connection with the base 100 and the abutment with the clamping member 102 form a stable heat conduction path for the electrode held by the clamping plate 200, effectively dissipating the heat generated during processing and preventing localized overheating from affecting processing accuracy and workpiece quality.

[0038] According to a preferred embodiment, such as Figures 4 to 6 As shown, the offset portion of the clamping member 102 and the base 100 forms a platform 103 for positioning and placing the clamping plate 200. The clamping member 102 is cylindrical. The platform 103 provides a flat and stable placement surface for the clamping plate 200, enabling the clamping plate 200 to be quickly positioned during installation and preventing it from shaking after placement, significantly improving the stability and positioning accuracy of the clamping plate 200 installation. Making the clamping member 102 cylindrical not only makes it easier to form during processing and manufacturing, reducing processing costs, but also allows for more even force distribution when fixed to the lathe, reducing stress concentration at the connection point with the lathe and enhancing the overall stability of the tooling on the lathe.

[0039] According to a preferred embodiment, the base 100 extends in a direction perpendicular to the axis of the positioning hole 101. Scale lines for assisting in positioning are provided on the base 100. The base 100 extending in a direction perpendicular to the axis of the positioning hole 101 makes the arrangement of the positioning holes 101 more in line with the spatial requirements of the machining operation, facilitating the installation and removal of bolts, and at the same time optimizing the fitting space between the base 100 and the surrounding components; the scale lines on the base 100 can provide an accurate numerical reference for the installation position of the clamping plate 200, and the operator can quickly adjust the position of the clamping plate 200 according to the scale lines to achieve precise positioning of the electrode to be machined, further improving the machining accuracy.

[0040] According to a preferred embodiment, the base 100 includes a horizontal plate 104 provided with a positioning hole 101 and a vertical plate 105 located above the horizontal plate 104 in the vertical direction. The vertical plate 105 is provided at one end in the extending direction of the horizontal plate 104 to form an "L" - shaped structure or a "丄" - shaped structure with the horizontal plate 104. As Figures 7 to 9 shown, heat - conducting members are provided at one end of the horizontal plate 104 close to the vertical plate 105, which are perpendicular to the vertical plate 105 and arranged at intervals. The heat - conducting members 106 extend in the vertical direction. The "L" - shaped or "丄" - shaped structure formed by the horizontal plate 104 and the vertical plate 105 greatly enhances the overall rigidity of the base 100 compared with a single flat - plate structure, is not easily deformed during the machining process, and ensures the structural stability of the base 100; the heat - conducting members 106 provided at one end of the horizontal plate 104 close to the vertical plate 105 and extending in the vertical direction increase the contact area with the air, and at the same time further broaden the heat - conducting path, can conduct the heat on the base 100 more quickly, improve the overall heat - dissipation efficiency, ensure that the electrode to be machined maintains a stable temperature state during the machining process, and can improve the thermal stability of the workpiece to be machined, controlling the electrode temperature difference within ±5°C.

[0041] According to a preferred embodiment, as Figures 10 to 12 shown, the clamping plate 200 is set as a rectangular horizontal structure. At least two clamping holes 202 are provided on the clamping plate 200, which are horizontally arranged and symmetric about the axis of the clamping plate 200. The clamping plate 200 with a rectangular horizontal structure has regular edges, facilitating the operator to grasp the position during installation and adjustment, and the horizontal setting makes its contact with the electrode to be machined more sufficient; at least two clamping holes 202 symmetrically arranged about the axis of the clamping plate 200 can apply balanced clamping forces from both sides when clamping the electrode to be machined, avoiding the electrode to be machined from tilting or shifting due to uneven force, and ensuring the stability of the workpiece during the machining process.

[0042] According to a preferred embodiment, the clamping plate 200 is further provided with at least two elongated holes 207 located between at least two clamping holes 201 and used for adjusting the clamping size. The at least two elongated holes 207 are symmetrically arranged along the axis of the clamping plate 200. Because the elongated holes 207 are located between at least two clamping holes 201 and are symmetrically arranged along the axis of the clamping plate 200, when the size of the electrode to be processed changes slightly, the position of the bolts within the elongated holes 207 can be adjusted to accommodate electrodes of different sizes without replacing the clamping plate 200. This greatly enhances the flexibility of the tooling in adapting to electrodes of different specifications and expands the scope of application of the tooling.

[0043] According to a preferred embodiment, the vertically downward end of the rectangular horizontally structured clamping plate 200 is provided with at least three fixing holes 201 corresponding to the positioning holes 101. The at least three fixing holes 201 are symmetrically arranged along the axis of the clamping plate 200. This symmetrical arrangement of the at least three fixing holes 201 at the vertically downward end of the rectangular clamping plate 200 ensures that when the bolt passes through the fixing holes 201 and connects to the positioning holes 101, the connection force between the clamping plate 200 and the base 100 is evenly distributed on the clamping plate 200. This prevents the clamping plate 200 from warping or shifting due to uneven connection force, ensuring the stability of the clamping plate 200 during processing and providing a stable clamping environment for the electrode to be processed.

[0044] According to a preferred embodiment, the tooling further includes a clamping bolt 205 for clamping the workpiece to be processed and a washer 206 that cooperates with the clamping bolt 205 to fix the workpiece to be processed. The washer 206 is as follows: Figure 16 As shown. When the clamping bolt 205 passes through the clamping hole 202 and other positions, it works in conjunction with the washer 206. The washer 206 increases the contact area between the clamping bolt 205 and the workpiece to be processed. This not only avoids damage to the workpiece surface caused by the clamping bolt 205 directly pressing the workpiece, but also enhances the fixing force on the workpiece. It effectively prevents the workpiece from loosening or shifting due to vibration or other reasons during processing, ensuring processing accuracy and operational safety.

[0045] Example 2

[0046] This embodiment is a further supplement to the above embodiment, and repeated content will not be described again.

[0047] According to a preferred embodiment, such as Figures 13 to 15As shown, the clamping plate 200 is configured as an inclined structure combining trapezoidal and rectangular shapes. The clamping plate 200 has a first clamping hole 203 and a second clamping hole 204 arranged at staggered vertical heights. The vertical height of the first clamping hole 203 is lower than that of the second clamping hole 204. The inclined structure of the clamping plate 200, combining trapezoidal and rectangular shapes, can accommodate electrodes with inclined angles, making the electrode clamping more closely fit its shape. The staggered vertical heights of the first clamping hole 203 and the second clamping hole 204 correspond to different clamping positions on the electrode, meeting the clamping requirements at different heights. For electrodes with complex shapes, it provides more stable clamping, broadening the tooling's adaptability to complex workpieces.

[0048] According to a preferred embodiment, the clamping plate 200, which is an inclined structure combining trapezoidal and rectangular shapes, has at least two fixing holes 201 corresponding to the positioning holes 101 at its vertically downward end. The distances between the at least two fixing holes 201 and the boundaries of the clamping plate 200 are unequal. The horizontal distance between the first clamping hole 203 and the boundary of the clamping plate 200 is greater than the horizontal distance between the second clamping hole 204 and the boundary of the clamping plate 200. This differentiated design allows for precise matching of the shape and clamping requirements of electrodes of specific specifications, resulting in tighter contact between the clamping plate 200 and the electrode during clamping, further improving clamping accuracy and stability, and reducing workpiece wobbling during processing.
