Description

Technical Field

[0001] The present invention relates to the technical field of workbenches, and particularly to an angle-adjustable workbench for sculpture carving. Background Art

[0002] Sculpture is a plastic art, a visual art of three-dimensional images made of material materials and means. Sculpture was originally mainly created by carving on materials such as stone, metal, wood, and ceramics. However, modernist sculptures have a high degree of freedom in materials and creation techniques, and can be created on various different materials by using carving, welding, or casting methods;

[0003] In the existing workbenches for manual sculpture carving, during use, when performing some complex carving operations on its top, it is necessary to tilt it. However, when the carving object is tilted in the existing device, after being clamped, it is not easy to well adapt to the position where the staff carves, affecting the operation accuracy of the user, reducing the quality of the carving object, and thus increasing the scrap rate of the carving object. For this reason, we propose an angle-adjustable workbench for sculpture carving.

[0004] Combining the above problems, we will find that the existing workbenches on the market are very difficult to avoid the above-mentioned problems simultaneously during use, and even if they can be solved, they need to be solved with the cooperation of external tools, thus unable to achieve the desired effect.

A sixth spring 23115 is fixedly connected to one side of the limit block 2313. One end of the sixth spring 23115 is fixedly connected to the inner cavity of the limit box 2311; By designing the tension spring 23114, when the restraint plate 23112 tilts to the right, it pulls the pull plate 23110 upward.

[0043] A groove 23210 is formed in the inner cavity of the arc groove 2325. The bottom of the retaining piece 2326 is slidably connected to the groove 23210. A seventh spring 23211 is fixedly connected to the inner cavity of the groove 23210. The other end of the seventh spring 23211 is fixedly connected to one side of the retaining piece 2326. A dial 23212 is fixedly connected to one side of the retaining piece 2326. The shape of the clamping block 2329 is a right trapezoid. The top of the support column 2324 is designed to be spherical. By setting the seventh spring 23211, when the retaining piece 2326 is not affected by external forces, the retaining piece 2326 resets under the action of the seventh spring 23211. By setting the dial 23212, it is convenient for the user to manually drive the retaining piece 2326. By setting the shape of the clamping block 2329 to be a right trapezoid, during the engagement process of the clamping block 2329 and the through hole 23213, the inclined surface facilitates the movement of the retaining piece 2326 to the left, and the clamping block 2329 can disengage from the through hole 23213, facilitating the release of the limit. By setting the top of the support column 2324 to be spherical, it can better support the placement table 4 while not affecting the inclination of the placement table 4;

[0044] By setting the combined use of the offset unit 21, the inclination unit 22 and the self-locking limit unit 23, when the user inclines the carving object, the inclination rotation point at the bottom of the carving object can move to the place opposite to the inclination direction, so that the distance between the top of the carving object and the user remains constant, avoiding the problem that the distance between the top of the carving object and the user is too close due to the inclination angle, thus not affecting the user's operation on the carving object, ensuring the quality of the carving object and reducing the scrap rate of the carving object.

[0045] The specific implementation manner of this embodiment is as follows: When the staff needs to perform engraving work, the first disc bearing 12 can drive the fixed box 211 to rotate. The user rotates the fixed box 211 to the required angle according to the need, and then manually tilts the placement table 4. The second disc bearing 3 can drive the placement table 4 to rotate, which can change the orientation of the engraving object in all directions. The connecting frame 229 at the bottom of the placement table 4 drives the rotating shaft 227 to rotate. The rotating shaft 227 drives the tooth plate 225 to move downward through the gear 228. The tooth plate 225 drives the support pulley 224 to move downward through the slide plate 223. The support pulley 224 drives the driving plate 213 to move downward. The driving pulley 214 on the right side of the driving plate 213 drives the moving block 215 to move to the right through the driving block 216. The moving block 215 drives the support box 221 to move to the right. The support box 221 drives the mounting frame 226 to move to the right. The moving distance of the mounting frame 226 is changed according to the tilt angle. The movement of the mounting frame 226 can change the rotation point at the bottom of the engraving object, so that the distance between the top of the engraving object and the user is always within a constant range. At the same time, the rotation of the rotating shaft 227 drives the limit tooth piece 2312 to rotate. At this time, the right limit block 2313 can resist the limit tooth piece 2312, so that the engraving object can hover at any angle. When the engraving object needs to be reset, just tilt the engraving object to a certain angle, and the placement table 4 drives the baffle 2323 to move through the support column 2324. When the baffle 2323 moves to the same horizontal line as the through hole 23213, under the action of the fifth spring 2328 on the block 2329, the block 2329 extends outward and engages with the through hole 23213, and the tilt angle reaches the maximum safety value. At this time, the slide plate 223 in the inner cavity of the support box 221 contacts the inclined rod 22113, but the inclined rod 22113 is not stressed. Then the user manually drives the retaining piece 2326 to rotate through the paddle 23212, so that the through hole 23213 is disengaged from the block 2329. At this time, tilt the placement table 4 again, and the slide plate 223 in the inner cavity of the support box 221 moves downward again. The slide plate 223 drives the constraint plate 23112 to tilt through the inclined rod 22113. Under the action of the tension spring 23114, the pull plate 23110 resets upward. The pull plate 23110 drives the sliding frame 2318 to move upward through the pull rod 2319. The sliding frame 2318 drives the turntable 2315 to rotate through the guide post 2317. The turntable 2315 drives the axe-shaped block 2316 to rotate through the fixed shaft 2314, changing the limiting direction of the limit tooth piece 2312. Under the action of the third spring 2210, the moving block 215 resets. At the same time, under the action of the first spring 217 and the second spring 218, the slide plate 223 moves upward. The slide plate 223 drives the gear 228 to rotate in the reverse direction through the tooth plate 225. The gear 228 drives the placement table 4 to reset through the rotating shaft 227 and the connecting frame 229. Under the action of the fourth spring 2322 on the baffle 2323, the baffle 2323 drives the support column 2324 to move upward to assist in supporting the placement table 4. Under the action of the seventh spring 23211,The retaining piece 2326 is reset. During the reuse process, simply press the sliding frame 2318. The sliding frame 2318 drives the turntable 2315 to rotate through the guide post 2317. The turntable 2315 drives the ax-shaped block 2316 to rotate through the fixed shaft 2314, and the limiting direction of the limiting tooth piece 2312 is changed again. At this time, due to the function of the guide groove 23111, according to the reason of pressing self-locking, the limiting direction of the fixed limiting tooth piece 2312 is set. By using the offset unit 21, the inclination unit 22 and the self-locking limiting unit 23 in cooperation, when the user inclines the carving object, the tilting rotation point at the bottom of the carving object can be moved to the place opposite to the tilting direction, so that the distance between the top of the carving object and the user remains constant, avoiding the problem that the distance between the top of the carving object and the user is too close due to the tilting angle, thus not affecting the user's operation of the carving object, ensuring the quality of the carving object and reducing the rejection rate of the carving object.

[0046] Embodiment 2: Please refer to Figures 1-9 , the present invention provides a technical solution: an angle-adjustable workbench for sculpture carving, and the present invention makes corresponding improvements to the technical problems mentioned in the background art.

[0047] As a further limitation of the present invention, an auxiliary protection mechanism 5 is provided on the left side of the inclination offset mechanism 2, and the auxiliary protection mechanism 5 is located on one side of the offset unit 21.

[0048] The auxiliary protection mechanism 5 includes an electric push rod 51. The electric push rod 51 is fixedly connected to one side of the fixed box 211 through a mounting block. The output end of the electric push rod 51 is movably connected to a protective ring 52 through a damping shaft, and a knob 53 is provided between the protective ring 52 and the electric push rod 51.

[0049] The specific implementation manner of this embodiment is: when the carving object is inclined, since the electric push rod 51 is fixedly connected to the fixed box 211, the electric push rod 51 can always be located below the inclined carving object. The output end of the electric push rod 51 can drive the protective ring 52 to move up and down, and the support height is determined according to needs to avoid the protective ring 52 affecting the user. The inclination angle of the protective ring 52 is manually adjusted through the knob 53; ensure that the protective ring 52 is parallel to the carving object to improve the protection effect. By providing the auxiliary protection mechanism 5, additional protection can be provided to the carving object during the inclination process of the carving object, and the carving object can be blocked when the bottom of the carving object is separated from the placement table 4 to prevent the carving object from being damaged, further ensuring the quality of the carving object and reducing the economic cost.
