It should be noted that the following are only some specific embodiments of the concept of the present utility model, and only a part of the embodiments of the present utility model. The specific and direct descriptions of the relevant structures are only for the convenience of understanding the present utility model, and each specific feature does not of course and directly limit the scope of implementation of the present utility model. Conventional selections and substitutions made by those skilled in the art under the guidance of the concept of the present utility model should be regarded as within the scope of protection required by the present utility model.

[0041] Such as Figures 1-9As shown in the figure, the utility model discloses a rotary wood carving clamp, which comprises a base 1, a rotating seat 2, a first clamping assembly 3 and a second clamping assembly 4; the rotating seat 2 is in the shape of a flat circular ring, so that a through hole 21 is vertically penetrated along the inner circumference of the rotating seat 2. The rotating seat 2 is rotatably installed above the base 1 and rotates around the axis of the rotating seat 2. A support table 22 is arranged above the rotating seat 2; the number of the first clamping assemblies 3 is 4 groups, and they are arranged along the circumference of the support table 22. Each first clamping assembly 3 is used to clamp the outer circumference of the annular wood carving 6. Preferably, each first clamping assembly 3 is detachably arranged on the rotating seat 2; the second clamping assembly 4 includes a second screw 41, a second thrust bearing 42 and a second clamp 43. Among them, a second screw hole 11 is arranged on the base 1. The second screw 41 passes through the through hole 21 from top to bottom and is threadedly connected with the second screw hole 11 to perform lifting. The second thrust bearing 42 and the second clamp 43 are both sleeved on the outer circumference of the second screw 41, and the second thrust bearing 42 is located above the second clamp 43 and below the head of the second screw 41.

[0042] Therefore, 1. When carving the upper and lower surfaces of the columnar or annular wood carving 6, the second clamping assembly 4 can be removed, and the wood carving 6 is placed on the support table 22. Then, each first clamping assembly 3 clamps the outer circumference of the lower end of the wood carving 6 to fix the wood carving 6 relative to the rotating seat 2. Thus, the upper end of the wood carving 6 is completely presented for the engraver to perform carving operations. And the wood carving 6 can rotate with the rotating seat 2 to change its orientation, enabling the engraver to more conveniently carve the upper end of the wood carving 6. After the upper end of the wood carving 6 is carved, it can be turned up and down so that the previously uncarved lower surface of the wood carving 6 faces up for carving. 2. When carving the side surface of the annular wood carving 6, the first clamping assembly 3 can be removed, and the wood carving 6 is placed on the support table 22. Then, the second screw 41 passes through the inner circumference of the wood carving 6 and is threadedly engaged with the second screw hole 11 below to clamp the upper surface of the wood carving 6 through the second clamp 43 to fix the wood carving 6 and the rotating seat 2, so that the side surface of the wood carving 6 is completely presented for the engraver to perform carving operations. And due to the setting of the second thrust bearing 42, when the second screw 41 maintains a stable threaded rotation state, the second clamp 43 can rotate relative to the base 1 to ensure that the wood carving 6 rotates with the rotating seat 2 to change the orientation of the wood carving 6, enabling the engraver to more conveniently carve the side surface of the wood carving 6.

[0043] Among them, the axis of the second screw 41 is coaxially arranged with the axis of the rotating seat 2.

[0044] Preferably, an inclined clamping surface 431 that flares upward is provided on the outer periphery of the lower end of the second fixture 43 in this embodiment, such that the inclined clamping surface 431 can cooperate with the upper edge of the inner periphery of the annular wood carving 6 to play a role in automatic alignment. After alignment, the inner periphery of the wood carving 6, the second screw 41, and the rotating base 2 are coaxial, facilitating rotary carving, especially for carving circumferentially continuous patterns.

[0045] In addition, the second clamping assembly 4 includes a second gasket 44. The second gasket 44 is sleeved on the outer periphery of the second screw 41. The upper end of the second gasket 44 abuts against the lower end of the head of the second screw 41, and the lower end of the second gasket 44 abuts against the upper end of the second thrust bearing 42, such that the second gasket 44 connects between the head of the second screw 41 and the second thrust bearing 42 to ensure effective connection between the two.

[0046] Preferably, the second gasket 44 is provided with a second positioning ring portion 441 that extends into the inner periphery of the second thrust bearing 42 and abuts against the inner peripheral wall of the second thrust bearing 42, making the positioning of the second thrust bearing 42 more accurate.

[0047] In addition, an embedded groove 12 is provided in the base 1, and the vertical projection of the second clamping assembly 4 falls within the through hole 21. When the second clamping assembly 4 is not needed, the second screw 41 screws downward so that the second thrust bearing 42 and the second fixture 43 pass through the through hole 21 and enter the embedded groove 12, and the second clamping assembly 4 is parallel to or lower than the support table surface 22, thus preventing the second clamping assembly 4 from being disassembled from the base 1 and lost during disassembly and assembly, and ensuring that the second clamping assembly 4 does not interfere with the wood carving 6 placed on the rotating base 2 by an internal placement method.

[0048] Among them, the first clamping assembly 3 in this embodiment includes a first bolt 31 and a first fixture 32. Adjustment slide rails 23 are respectively provided on the support table surface 22 corresponding to each first clamping assembly 3, and the track direction of the adjustment slide rails 23 extends from the outer periphery to the inner periphery along the radial direction of the rotating base 2. In addition, second teeth 24 are provided at the bottom of the adjustment slide rails 23 along the track direction. The first fixture 32 includes a first slider 321 slidably disposed and a first clamping block 322 located above the support table surface 22. A first tooth 323 that cooperates with the second teeth 24 is provided at the bottom of the first slider 321. A first screw hole 25 is provided at the bottom of the adjustment slide rail 23, and a vertically penetrating mounting through hole 324 is provided on the first slider 321, and the mounting through hole 324 is elongated along the track direction of the adjustment slide rail 23. A first screw penetrates through the mounting through hole 324 and is threadedly engaged with the first screw hole 25 to push the first slider 321 downward to achieve the engagement of the first tooth 323 and the second teeth 24.

[0049] Preferably, there are two sets of second teeth 24 in each adjustment slide rail 23, and they are arranged along the direction perpendicular to the track of the adjustment slide rail 23, while the first screw hole 25 is arranged between the two sets of second teeth 24. Correspondingly, the first teeth 323 and the mounting through holes 324 are arranged in the same way.

[0050] Preferably, the number of the first screw holes 25 on the adjustment slide rail 23 in this embodiment is 4, and they are arranged along the track direction of the adjustment slide rail 23, so that the length of the mounting through holes 324 can be made smaller through the arrangement of multiple first screw holes 25, and the length of the first slider 321 can be made smaller.

[0051] Preferably, an elastic member 325 is fixedly arranged on the first clamping block 322 by means of pasting, clamping, etc. to clamp the wood carving 6 through the elastic member 325 in contact with the wood carving 6, so that the elastic deformation of the elastic member 325 can effectively clamp the wood carving 6 within the tooth pitch gap of the teeth, and the elastic clamping has a protective effect on the wood carving 6.

[0052] Specifically, a first mounting groove 13 and a second mounting groove 14 are arranged above the base 1. The second mounting groove 14 is located below the first mounting groove 13. A first thrust bearing 5 is arranged in the second mounting groove 14. Part or all of the rotating seat 2 is placed in the first mounting groove 13 and is supported above the first thrust bearing 5.

[0053] The first mounting groove 13 and the second mounting groove 14 have an internal function for the first thrust bearing 5 and the rotating seat 2, so that the overall volume is smaller, and the internal structure is not easily disturbed and works more stably.

[0054] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present invention. Various modifications to these embodiments will be apparent to those skilled in the art. The general principles defined herein can be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but will be accorded the widest scope consistent with the principles and novel features disclosed herein.
