Description

Technical Field

[0001] This utility model belongs to the field of carving and fixing technology, and in particular relates to a carving and fixing device for handicrafts. Background Technology

[0002] A carving fixture is a specialized device used to securely hold a craft during the carving process. It uses a mechanical structure to fix the craft on the workbench, preventing it from shifting due to vibration or rotation during processing, thus ensuring carving accuracy and efficiency. This is especially important for techniques like nut carving, which requires carving and relief on tiny curved surfaces, where the margin for error is extremely low.

[0003] Based on the above, the inventors have discovered the following shortcomings in existing craft carving fixing devices:

[0004] 1. The hardness of the fruit pit clamping surface is relatively high, which can easily cause indentations on the fruit pit, or even crack the fruit pit to be carved. It is not convenient to add flexible contact measures to the device to avoid indentations on the fruit pit surface.

[0005] 2. As the carving progresses, the fruit pit needs to be disassembled and clamped multiple times, resulting in low carving efficiency. It is inconvenient to add rotation adjustment measures to the device to rotate the fruit pit for carving adjustment. Utility Model Content

[0006] To address the aforementioned technical problems, this utility model provides a craft carving fixing device. This addresses the issues of existing fruit pit clamping surfaces having high hardness, easily causing indentations or even cracking the fruit pits to be carved, making it inconvenient to add flexible contact measures to the device to prevent indentations; and the need for repeated disassembly and clamping of the fruit pit as carving progresses, resulting in low carving efficiency, and the inconvenience of adding rotational adjustment measures to the device to rotate the fruit pit for carving adjustments.

[0007] The purpose and function of this utility model's craft carving fixing device are achieved through the following specific technical means:

[0008] A craft carving fixing device includes a device body; the device body is provided with a bearing clamping column, the outer circumference of the bearing clamping column is provided with an anti-slip groove array, the front end face of the bearing clamping column is provided with a fixing column, the rear end face of the bearing clamping column is provided with a regular hexagonal groove, a rubber contact pad is inserted into the regular hexagonal groove of the bearing clamping column, the front end face of the rubber contact pad is provided with a regular hexagonal prism, and the rear end face of the rubber contact pad is provided with a frustum groove.

[0009] Furthermore, a rubber protective pad is inserted inside the regular hexagonal groove of the elastic clamping column, a regular hexagonal prism is provided on the rear end face of the rubber protective pad, and a conical groove is provided on the front end face of the rubber protective pad.

[0010] Furthermore, a tensioning clamping column is mounted on the fixed column of the clamping rotating rod via a bearing. The tensioning clamping column has an anti-slip groove arranged in annular array around its outer circumference. A bearing groove is opened on the rear end face of the tensioning clamping column, and a regular hexagonal groove is opened on the front end face of the tensioning clamping column.

[0011] Furthermore, a clamping rotating rod is installed inside the threaded hole of the clamping bearing block, the outer circumference of the clamping rotating rod is threaded, a fixing post is provided on the front end face of the clamping rotating rod, and a rotating circular plate with anti-slip groove is provided on the rear end of the clamping rotating rod.

[0012] Furthermore, an assembly bearing plate is bolted to the bottom of the bearing block. The bottom end face of the assembly bearing plate has stepped holes that extend vertically through both the front and rear ends and the left and right sides. A clamping bearing block is bolted to the middle of the rear end face of the top end face of the assembly bearing plate. The top of the clamping bearing block has a semi-circular head. The center of the clamping bearing block has a threaded hole that extends vertically through both the front and rear ends. Threaded blind holes are provided on the left and right sides of the bottom end face of the clamping bearing block.

[0013] Furthermore, an anti-rotation locking button is installed inside the threaded hole of the bearing force block, a threaded post is provided behind the anti-rotation locking button, and a rotating circular plate with anti-slip groove is provided at the front end of the threaded post of the anti-rotation locking button.

[0014] Furthermore, a bearing block is installed on the fixed column of the bearing clamping column via a bearing. The top of the bearing block is provided with a semi-circular head, the rear end face of the bearing block is provided with a bearing groove, the center of the bearing block is provided with a threaded hole that runs through the front and rear, and the bottom end face of the bearing block is provided with threaded blind holes on both the left and right sides.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] The rubber contact pad is convenient to insert into the bearing clamping column to prevent rotation, and the bearing clamping column can be used to clamp and fix the fruit pit through the contact of the rubber contact pad. This solves the problem that the hardness of the fruit pit clamping surface is high, which can easily cause indentation on the fruit pit, or even crack the fruit pit to be carved. It is also inconvenient to add flexible contact measures to the device to avoid indentation on the fruit pit surface.

[0017] The bearings facilitate the rotation of the bearing-supporting clamping column and the loose clamping column. The bearing-supporting clamping column and the loose clamping column can clamp the fruit pit through rubber contact pads and rubber protective pads to achieve rotation adjustment. At the same time, the rotation can be locked by tightening the bearing-supporting clamping column with the anti-rotation locking button. This solves the problem that the fruit pit needs to be disassembled and clamped multiple times as the carving progresses, resulting in low carving efficiency and the inconvenience of adding rotation adjustment measures to the device to rotate the fruit pit for carving adjustment.

The bearing clamping column 2 has an anti-slip groove arranged in a circular array on its outer circumference to facilitate the rotation and adjustment of the fruit pit. The front end face of the bearing clamping column 2 is provided with a fixing column to facilitate the installation of the bearing force block 4 through a bearing. The rear end face of the bearing clamping column 2 has a regular hexagonal groove to facilitate the insertion and synchronous rotation of the rubber contact pad 3. The rubber contact pad 3 is inserted into the regular hexagonal groove of the bearing clamping column 2 to facilitate contact and protection with the fruit pit and prevent the fruit pit from being indented. The front end face of the rubber contact pad 3 is provided with a regular hexagonal prism to facilitate insertion into the regular hexagonal groove of the bearing clamping column 2. The rear end face of the rubber contact pad 3 has a frustum groove to facilitate the larger end of the fruit pit to be inside. The fixing column of the bearing clamping column 2 is provided with... A bearing-loaded block 4 is installed via a bearing, facilitating the rotation of the bearing clamping column 2. The top of the bearing-loaded block 4 has a semi-circular head to prevent scratching of the engraving personnel. A bearing groove is provided on the rear end face of the bearing-loaded block 4 for easy installation of the bearing clamping column 2 via the bearing. A through-hole threaded hole is provided in the center of the bearing-loaded block 4 for easy installation of the anti-rotation locking button 5 via threads. Threaded blind holes are provided on both sides of the bottom end face of the bearing-loaded block 4 for easy assembly of the bearing plate 6 via bolts. An anti-rotation locking button 5 is installed inside the threaded hole of the bearing-loaded block 4, allowing it to press against the bearing clamping column 2 to prevent rotation. A threaded post is provided behind the anti-rotation locking button 5 for easy installation via threads. A rotating circular plate with anti-slip grooves is provided at the front end of the threaded post of the anti-rotation locking button 5 to facilitate rotation and prevent slippage.

[0028] The load-bearing block 4 has an assembly bearing plate 6 bolted to its bottom for supporting various components. The assembly bearing plate 6 has stepped holes running vertically through both ends and sides of its bottom end face for bolted installation of the load-bearing block 4 and the clamping bearing block 7. The clamping bearing block 7 is bolted to the center of the rear end of the top end face of the assembly bearing plate 6 for supporting the clamping rotating rod 8. The clamping bearing block 7 has a semi-circular head at its top to prevent scratching the engraving personnel. A threaded hole running through the center of the clamping bearing block 7 allows for threaded installation of the clamping rotating rod 8. Threaded blind holes are located on both sides of the bottom end face of the clamping bearing block 7 for bolted installation of the assembly bearing plate 6. The clamping rotating rod 8 is installed inside the threaded hole of the clamping bearing block 7, allowing it to move back and forth through threaded engagement. Threads are also present on the outer circumference of the clamping rotating rod 8 for threaded installation. A fixed post is provided on the front end to facilitate the installation of the clamping post 9 via bearings. A rotating circular plate with anti-slip grooves is provided at the rear end of the clamping rotating rod 8 to facilitate the rotation and anti-slip of the clamping rotating rod 8. The clamping post 9 is installed on the fixed post of the clamping rotating rod 8 via bearings to facilitate the rotation of the clamping post 9 via bearings. The outer circumference of the clamping post 9 is provided with anti-slip grooves in an array to facilitate the rotation and anti-slip of the clamping post 9. A bearing groove is opened on the rear end face of the clamping post 9 to facilitate the installation of the clamping rotating rod 8 via bearings. A regular hexagonal groove is opened on the front end face of the clamping post 9 to facilitate the insertion of the rubber protective pad 10 for synchronous rotation. The rubber protective pad 10 is inserted into the regular hexagonal groove of the clamping post 9 to facilitate contact and protection with the tip of the fruit pit. A regular hexagonal prism is provided on the rear end face of the rubber protective pad 10 to facilitate insertion into the regular hexagonal groove of the clamping post 9. A conical groove is opened on the front end face of the rubber protective pad 10 to facilitate the tip of the fruit pit being inside.

[0029] The specific usage and function of this embodiment are as follows:

[0030] In this utility model, such as Figure 1As shown, the device body 1 is in use. At this time, a fruit pit is clamped and fixed between the rubber contact pad 3 and the rubber protective pad 10. The frustum groove design of the rubber contact pad 3 can adapt to the larger ends of fruit pits of different sizes. Simultaneously, the elastic buffering properties of the rubber material prevent the clamping pressure from causing indentations or cracks in the fruit pit. Similarly, the rubber protective pad 10 fixes the tip of the fruit pit through a conical groove, thus forming a two-way flexible clamping structure. This solves the problem that the high hardness of the fruit pit clamping surface easily causes indentations or even cracks the fruit pit to be carved. During the carving process, the operator can manually rotate the bearing clamping column 2 or the loosening clamping column 9 through the anti-slip groove. This causes the bearing clamping column 2 or the loosening clamping column 9 to rotate and adjust the fruit pit through the rubber contact pad 3 or the rubber protective pad 10. This solves the problem that the fruit pit needs to be disassembled and clamped multiple times as the carving progresses, resulting in low carving efficiency. When the fruit pit needs to be fixed, tighten the anti-rotation locking button 5 so that its threaded column presses against the bearing clamping column 2, as shown in the figure. Figure 3 As shown, this achieves the anti-rotation of the bearing clamping column 2, and then the bearing clamping column 2 prevents the rubber contact pad 3 from rotating, and the rubber contact pad 3 prevents the kernel from rotating, thereby preventing the kernel from rotating during carving. At the same time, the clamping rotating rod 8 pushes the tightening clamping column 9 to move back and forth through the thread engagement, thereby realizing the clamping and loosening of the kernel.

[0031] Example 2: The difference from Example 1 is that the rear end face of the threaded post of the anti-rotation locking button 5 can also be set as a frosted surface, thereby increasing the friction between the rear end face of the threaded post of the anti-rotation locking button 5 and the bearing clamping post 2, and preventing the anti-rotation locking button 5 from rotating and loosening.

[0032] Example 3: The difference from Example 1 is that the outer circumferential surface of the rotating plate holding the rotating rod 8 can also be set as a frosted surface, thereby increasing the friction between the outer circumferential surface of the rotating plate holding the rotating rod 8 and the hand, and preventing the rotating rod 8 from slipping during rotation.
