A hollowing and polishing mechanism and method for a wood carving ornament

Abstract

The present invention relates to a hollow grinding mechanism for wood carving ornaments, which belongs to the technical field of grinding of wood carving ornaments. It includes a device support, a grinding slide rail, a driving seat provided with a driving wheel, and a grinding seat provided with a grinding disc. A support mechanism is pushed out by a driving push rod and a grinding push rod, so that the column of the support mechanism pushes the driving seat and the grinding seat installed at its end to extend into the ghost ball through the through hole on the ghost ball. The driving wheel on the driving seat contacts the inner ball of the ghost ball with the grinding disc on the grinding seat, and the inner ball is driven to rotate by the driving wheel. The friction generated between the inner ball and the grinding disc grinds the inner ball. By pushing out the driving push rod and the grinding push rod, the support leg rod deflects, and the support spring piece at the end of the support leg rod extends into the gap between the inner ball and the outer ball of the ghost ball. As the support leg rod deflects, the end of the support spring piece contacts the inner side wall of the outer ball and forms a support for the outer side wall, so that the outer ball is separated from the inner ball, facilitating the grinding operation of the inner ball.

Description

Technical Field

[0001] The present invention relates to the technical field of carving ornament polishing, and particularly relates to a hollow carving and polishing mechanism and method for carving ornaments. Background Art

[0002] As a treasure of traditional Chinese handicrafts, wood carving is a "fine woodworking" technique separated from woodworking. It is mainly divided into three categories: three-dimensional round carving, root carving, and relief carving. The carving ornaments of wood carving, which combine artistry and practicality, can not only be used as home decorations to enhance cultural taste but also be used as investment collections. Their value increases significantly with the complexity of the process, historical background, and the attributes of famous artists' works.

[0003] In the hollow carving process of wood carving, there is a carving method called the ghost ball, which is to carve a freely rotating inner ball in a solid outer ball. This carving method involves uniformly opening a plurality of through holes on the solid outer ball in advance, then using a T-shaped cutter to cut and separate the connection between the inner ball and the outer ball, and finally obtaining a wood carving with a ball-in-ball structure through grinding and polishing operations.

[0004] When grinding and polishing this hollow-structured ball-in-ball, since the inner ball is inside the outer ball, it is not convenient to separate and position the inner ball and the outer ball when grinding and polishing the inner ball. The rotation of the inner ball easily drives the outer ball to rotate under the action of friction, which is not conducive to grinding and polishing the inner ball. Summary of the Invention

[0005] What the present invention aims to overcome is the problem that when grinding and polishing this hollow-structured ball-in-ball, since the inner ball is inside the outer ball, it is not convenient to separate and position the inner ball and the outer ball when grinding and polishing the inner ball. The rotation of the inner ball easily drives the outer ball to rotate under the action of friction, which is not conducive to grinding and polishing the inner ball. The purpose is to provide a hollow carving and polishing mechanism and method for carving ornaments.

[0018] A method for hollowing and polishing a wood carving ornament is as follows:

[0019] S1. Take the magic ball to be polished. Use the driving push rod and the polishing push rod to extend, and insert the supporting mechanisms on both of them into the through holes on the magic ball to position the magic ball, so that the driving wheel on the driving seat and the polishing disc on the polishing seat contact the inner ball of the magic ball;

[0020] S2. Use the driving wheel on the driving seat to rotate and drive the inner ball of the magic ball to rotate. When the inner ball rotates, the polishing disc contacts the surface of the inner ball to polish the inner ball.

[0021] The beneficial effects of the present invention are:

[0022] The driving push rod and the grinding push rod are used to push out the support mechanism, so that the upright post of the support mechanism pushes the driving seat and the grinding seat installed at its end to extend into the ghost ball through the through hole on the ghost ball. The driving wheel on the driving seat contacts the inner ball of the ghost ball with the grinding disc on the grinding seat. The inner ball is driven to rotate by the driving wheel, and the friction generated between the inner ball and the grinding disc grinds the inner ball.

[0023] By pushing out the driving push rod and the grinding push rod, the supporting foot rod deflects, and the supporting spring piece at the end of the supporting foot rod extends into the gap between the inner ball and the outer ball of the ghost ball. As the supporting foot rod deflects, the end of the supporting spring piece contacts the inner side wall of the outer ball and forms a support on the outer side wall, so that the outer ball is separated from the inner ball, facilitating the grinding operation of the inner ball.

[0024] Through the transmission between the eccentric wheel, the deflection rod, the first chute, the second chute, the limiting rod and the dial rod, the mounting seat is pushed to rotate intermittently. When the driving wheel on the mounting seat rotates to drive the inner ball to rotate, the rotation of the mounting seat is used to change the direction of the driving wheel to drive the inner ball to rotate, so as to facilitate the grinding disc to grind each position of the spherical surface.

Detailed implementation mode

[0036] In order to make the technical means, creative features, achieved purposes and effects of the present invention easy to understand, the present invention will be further described below with reference to specific drawings.

[0037] Embodiment 1:

[0038] As Figure 1-4 shown, a hollowing and grinding mechanism for a wood carving ornament includes a device bracket 1, a grinding slide rail 2, a driving seat 3 provided with a driving wheel 12, and a grinding seat 4 provided with a grinding disc 13;

[0039] A lower tray 21 and an upper tray 22 are provided on the device bracket 1. Support slideways 23 are respectively provided on the side parts of the upper tray 22 and the lower tray 21. The grinding slide rail 2 is slidably installed in the support slideways 23 on the side parts of the upper tray 22 and the lower tray 21. The grinding slide rail 2 is in a semi-circular structure. A moving seat 24 is slidably installed on the grinding slide rail 2. A grinding push rod 25 is fixedly installed on the moving seat 24. The grinding push rod 25 is arranged along the radius direction of the grinding slide rail 2. A driving push rod 26 is installed on the lower tray 21. The axis of the driving push rod 26 passes through the center of the grinding slide rail 2;

[0040] Support mechanisms 27 are respectively installed on the output ends of the driving push rod 26 and the grinding push rod 25. The support mechanism 27 includes a column 31, a fixed ring 32, a floating ring 33, a support foot rod 34, a connecting rod 35, a support spring plate 36, and a side support rod 39. The fixed ring 32 is fixedly installed on the column 31, and the floating ring 33 is slidably installed on the column 31. A support spring 37 is provided between the fixed ring 32 and the floating ring 33. One end of the support foot rod 34 is fixed to the fixed ring 32, and the other end is hinged to the side support rod 39. One end of the connecting rod 35 is hinged to the floating ring 33, and the other end is hinged to the side support rod 39. The upper end of the support spring plate 36 is hinged to the side support rod 39, and a buffer spring 38 is provided between the lower end and the side support rod 39. One end of the support foot rod 34 is hingedly installed on the fixed ring 32, and the other end is hinged to the support spring plate 36. One end of the connecting rod 35 is hinged to the floating ring 33, and the other end is hinged to the support foot rod 34. A buffer spring 38 is installed between the support spring plate 36 and the support foot rod 34. The driving seat 3 is installed at the end of the column 31 in the support mechanism 27 connected to the driving push rod 26, and the grinding seat 4 is installed at the end of the column 31 in the support mechanism 27 connected to the grinding push rod 25;

[0041] When grinding the inner ball of the ghost ball, the driving push rod 26 and the grinding push rod 25 are used to push out the support mechanism 27, so that the column 31 of the support mechanism 27 pushes the driving seat 3 and the grinding seat 4 installed at its end to extend into the ghost ball through the through hole on the ghost ball. The driving wheel 12 on the driving seat 3 contacts the inner ball of the ghost ball with the grinding disc 13 on the grinding seat 4. As the driving wheel 12 rotates, it drives the inner ball of the ghost ball to rotate. When the inner ball rotates, it is ground due to the friction generated with the grinding disc 13;

[0042] When the column 31 extends into the through hole, the floating ring 33 contacts the inner ball of the ghost ball in advance. As the driving push rod 26 and the grinding push rod 25 are pushed out, under the extrusion of the inner ball, the floating ring 33 squeezes the connecting rod 35, thereby pushing the side support rod 39 to deflect towards the inner side wall of the through hole on the outer ball. The support spring plate 36 on the side support rod 39 contacts the side wall of the through hole. Under the action of the buffer spring 38, a force is applied from the inside to the outside on the through hole to support and position the through hole, so that the outer ball and the inner ball are separated. When the inner ball rotates for grinding, the inner ball does not contact the outer side wall;

[0043] After the polishing is completed, as the driving push rod 26 and the polishing push rod 25 contract, the column 31 is withdrawn from the through hole on the ghost ball. At this time, under the action of the support spring 37 between the fixed ring 32 and the floating ring 33, the floating ring 33 moves away from the fixed ring 32, thereby pulling the connecting rod 35 to deflect. The angle between the connecting rod 35 and the support foot rod 34 increases. Thus, the support foot rod 34 deflects toward the column 31 side. As the support foot rod 34 deflects toward the column 31, the support spring piece 36 extending between the inner ball and the outer ball is withdrawn. Thus, the unloading operation of the ghost ball can be performed after the polishing is completed.

[0044] Embodiment 2:

[0045] On the basis of Embodiment 1, as Figure 1-6 shown, an auxiliary push rod 41 is fixedly installed on the upper tray 22, and a support mechanism 27 is installed at the output end of the auxiliary push rod 41; the auxiliary push rod 41 is coaxially arranged with the driving push rod 26. When clamping the ghost ball, the ghost ball is positioned by the prior cooperation of the auxiliary push rod 41 and the driving push rod 26. The inner ghost ball is clamped by the support foot rod 34 in the support mechanism 27 on the auxiliary push rod 41 and the support foot rod 34 in the support mechanism 27 on the driving push rod 26, which is convenient for subsequent adjustment of the position where the polishing disc 13 extends into the ghost ball and the contact position between the polishing disc 13 and the inner ball of the ghost ball. By adjusting the position of the polishing slide rail 2 in the support slideway 23 and the position of the moving seat 24 on the polishing slide rail 2, the position where the polishing push rod 25 is inserted into the ghost ball is adjusted;

[0046] A universal wheel 42 is installed on the floating ring 33. When the floating ring 33 contacts the inner ball spherical surface, the friction between the floating ring 33 and the inner ball is reduced by setting the universal wheel 42;

[0047] A driving rod 44 is coaxially arranged inside the column 31. The driving rod 44 is driven by a driving motor 51. A transmission mechanism 52 and a first connecting shaft 53 are provided on the driving seat 3. The first connecting shaft 53 drives the driving wheel 12 to rotate through the transmission mechanism 52. The first connecting shaft 53 is connected to the driving rod 44 in the column 31 installed on the driving seat 3. A second connecting shaft 54 is provided on the polishing seat 4. The second connecting shaft 54 connects the polishing disc 13. The second connecting shaft 54 is connected to the driving rod 44 in the column 31 installed on the polishing seat 4; the driving motor 51 is used to drive the driving rod 44 to rotate;

[0048] When the driving seat 3 is arranged at the end of the column 31, the driving rod 44 rotates to drive the driving wheel 12 on the driving seat 3 to rotate. When the driving wheel 12 contacts the inner ball, the inner ball is pushed to rotate by the frictional force on the inner ball surface;

[0049] When the end of the column 31 contacts the grinding seat 4, the driving rod 44 rotates to drive the second connecting shaft 54 to rotate, and then drives the grinding disc 13 on the grinding seat 4 to rotate, thereby performing a grinding operation on the inner ball surface;

[0050] The transmission mechanism 52 includes an intermediate shaft 71 and a transmission gear disc 72. One end of the intermediate shaft 71 is connected to the shaft end of the driving wheel 12 through a gear, and the other end is connected to the transmission gear disc 72 through a gear. The transmission gear disc 72 is fixedly installed on the first connecting shaft 53. When the driving rod 44 drives the first connecting shaft 53 to rotate, the first connecting shaft 53 drives the transmission gear disc 72 to rotate, the transmission gear disc 72 drives the intermediate shaft 71 to rotate, and the intermediate shaft 71 drives the driving wheel 12 to rotate;

[0051] The column 31 is hollow inside, and there is a ventilation port 61 at the end. There is an air guide port 62 on the side of the column 31. The air guide port 62 on the column 31 connected to the driving seat 3 is connected to the air outlet of the air pump 5 through a pipeline. The air inlet of the air pump 5 is connected to the air outlet of the dust collector 6. The air inlet of the dust collector 6 is connected to the air guide port 62 on the column 31 connected to the grinding seat 4 through a pipeline. The air pump 5 is used to drive the air flow to flow, and the air flow is ejected from the ventilation port 61 on the column 31 connected to the driving seat 3 to the spherical surface of the inner ball to clean the grinding dust on the spherical surface. The air guide port 62 on the column 31 connected to the grinding seat 4 is connected to the air inlet of the air pump 5 through the dust collector 6. The grinding dust is sucked into the dust collector 6 through the ventilation port 61 on the column 31, and the air flow filtered by the dust collector 6 can be pushed by the air pump 5 and ejected from the air guide port 62 on the column 31 connected to the driving seat 3 again. Thus, the dust generated by grinding can be collected, and the dust pollution during grinding can be reduced.

[0052] Embodiment 3:

[0053] On the basis of Embodiment 1, as Figure 1-10As shown, a mounting seat 81 is rotatably provided on the driving seat 3. The driving wheel 12, the intermediate shaft 71 and the transmission gear disc 72 are all mounted on the mounting seat 81. A worm gear 111 is mounted at the bottom of the mounting seat 81. A worm 112 is mounted on the driving seat 3. The worm gear 111 meshes with the worm 112. A secondary shaft 110 is rotatably mounted on the driving seat 3. The end of the secondary shaft 110 is connected to the worm 112 through a gear. A transmission disc 82 is rotatably mounted on the driving seat 3. An upper toothed ring 113 is provided on the upper part of the transmission disc 82. The upper toothed ring 113 drives the worm 112 to rotate through a gear connection. A lower toothed ring 114 is provided on the lower part of the transmission disc 82. A first bevel gear 83 is mounted on the first connecting shaft. A second bevel gear 84 is rotatably mounted on the driving seat 3. A synchronous rotating cylinder 85 is rotatably mounted on the driving seat 3. A third bevel gear 86 is mounted at the lower end of the synchronous rotating cylinder 85. The second bevel gear 84 is between the first bevel gear 83 and the third bevel gear 86 and meshes with both the first bevel gear 83 and the third bevel gear 86 at the same time. The first connecting shaft passes through the synchronous rotating cylinder 85. An eccentric wheel 87 is fixed on the synchronous rotating cylinder 85. A first sliding groove 88 is provided on the driving seat 3. A limiting rod 89 is slidably mounted in the first sliding groove 88. A deflecting rod 90 is hingedly connected to the limiting rod 89. An eccentric groove 91 is provided in the middle of the deflecting rod 90. The eccentric wheel 87 is located in the eccentric groove 91. A cooperating seat 92 is rotatably provided at the bottom of the transmission disc 82. A second sliding groove 93 is provided on the cooperating seat 92. A shifting rod 94 is slidably mounted in the second sliding groove 93. The other end of the deflecting rod 90 is hingedly connected to the shifting rod 94. Both the limiting rod 89 and the shifting rod 94 can extend outwards and be inserted into the tooth grooves of the lower toothed ring 114;

[0054] The shifting rod 94 and the limiting rod 89 are coaxially arranged. The distance between the end of the limiting rod 89 far from the eccentric groove 91 and the end of the shifting rod 94 far from the eccentric groove 91 is equal to the inner diameter length of the lower toothed ring 114. The eccentric groove 91 is a square groove. A buffer wheel 95 is provided at one end of the eccentric wheel 87 in contact with the side wall of the eccentric groove 91;

[0055] When the first connecting shaft 53 rotates, it drives the first bevel gear 83 to rotate. The first bevel gear 83 drives the third bevel gear 86 to rotate through the second bevel gear 84, and then drives the synchronous rotating cylinder 85 to rotate in the opposite direction relative to the first connecting shaft 53;

[0056] When the synchronous rotating cylinder 85 rotates, it drives the eccentric wheel 87 to rotate. The eccentric wheel 87 pushes the deflection rod 90 to move in the eccentric groove 91. When the buffer wheel 95 on the eccentric wheel 87 contacts the side of the eccentric groove 91 close to the limit rod 89, as the eccentric wheel 87 rotates and pushes the deflection rod 90 to move towards the limit rod 89, the end of the limit rod 89 penetrates out of the first chute 88 and inserts into the tooth groove on the lower tooth ring 114 under the thrust of the deflection rod 90. At the same time, under the pull of the deflection rod 90, the shift lever 94 also moves along the second chute 93 towards the first chute 88, and the end of the shift lever 94 separates from the tooth groove on the lower tooth ring 114. At this time, the insertion of the limit rod 89 into the lower tooth ring 114 can limit the lower tooth ring 114 and prevent it from rotating, thereby restricting the rotation of the transmission disc 82;

[0057] As the buffer wheel 95 on the eccentric wheel 87 moves from close to the limit rod 89 to close to the shift lever 94, under the push of the eccentric wheel 87, the deflection rod 90 deflects around the hinge point with the limit rod 89. The deflection of the deflection rod 90 drives the cooperative seat 92 to rotate relative to the mounting seat 81, thereby driving the overall swing of the second chute 93 and the shift lever 94. When the buffer wheel 95 moves to the side wall of the eccentric groove 91 close to the shift lever 94, under the push of the buffer wheel 95, the whole deflection rod 90 is driven to move towards the shift lever 94. At this time, the shift lever 94 is pushed to insert into the tooth groove on the lower tooth ring 114. At the same time, the deflection rod 90 pulls the limit rod 89 out of the tooth groove of the lower tooth ring 114. As the eccentric wheel 87 continues to rotate, the eccentric wheel 87 again pushes the deflection rod 90 to deflect around the hinge point with the limit rod 89. At this time, since the shift lever 94 has not completely disengaged from the tooth groove on the transmission disc 82, when the deflection rod 90 deflects, it drives the overall deflection of the shift lever 94, the second chute 93 and the cooperative seat 92. With the displacement of the shift lever 94 and the second chute 93, the lower tooth ring 114 is driven to rotate, and the lower tooth ring 114 drives the transmission disc 82 and the upper tooth ring 113 to rotate synchronously. The upper tooth ring 113 drives the mounting seat 81 to rotate through the auxiliary shaft 110, the worm wheel 111 and the worm 112, thereby driving the overall rotation of the mounting seat 81 and the driving wheel 12;

[0058] Through the transmission between the eccentric wheel 87, the deflection rod 90, the first chute 88, the second chute 93, the limit rod 89, the shift lever 94, the lower tooth ring 114, the transmission disc 82, the upper tooth ring 113, the auxiliary shaft 110, the worm wheel 111 and the worm 112, the intermittent rotation of the mounting seat 81 is promoted. When the driving wheel 12 on the mounting seat 81 rotates to drive the inner ball to rotate, the rotation of the mounting seat 81 is utilized to change the direction of the driving wheel 12 driving the inner ball to rotate;

[0059] A first locking rod 101 is threadedly connected to the moving seat 24. A friction wheel 102 is rotatably installed at the end of the first locking rod 101. The cross-section of the friction wheel 102 contacts and polishes the sliding rail 2. A first knob 103 is installed at the other end of the first locking rod 101. A support seat 104 is slidably installed in the support slideway 23. A second locking rod 105 is threadedly connected and installed on the support seat 104. One end of the second locking rod 105 contacts the support slideway 23, and a second knob 106 is installed at the other end. By pushing the support seat 104 to move in the support slideway 23, the polishing slide rail 2 is driven to rotate around the driving push rod 26, and the position of the moving seat 24 on the polishing slide rail 2 is adjusted to change the position where the polishing push rod 25 is inserted into the through hole on the magic ball.
