DETAILED DESCRIPTION

[0030] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0031] In addition, in the present invention, the descriptions of "first", "second", etc. are only used for descriptive purposes, and do not specifically refer to the order or sequence, nor are they used to limit the present invention. They are only used to distinguish components or operations described with the same technical terms, and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of technical features indicated. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In addition, the technical solutions and technical features between the various embodiments can be combined with each other, but they must be based on the ability of ordinary technicians in the field to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0032] The present invention provides the following embodiments:

[0033] Embodiment 1: The embodiment of the present invention provides a purple clay teapot engraving workbench with a convenient switching of engraving knives, such as Figure 1-Figure 4 As shown, it comprises a base plate 1, a leg 2 is respectively provided at the top corner of the lower end of the base plate 1, a rotating platform 4 is rotatably provided at the middle part of the upper end of the base plate 1, the rotating platform 4 and the base plate 1 are connected by a driving mechanism, a positioning mechanism is provided on the upper right side of the rotating platform 4, the positioning mechanism is used to fix the purple clay teapot on the rotating platform 4, a fixed shell 5 is provided on the upper left side of the base plate 1, the fixed shell 5 is connected to the connecting head 33 through a movable mechanism, and the connecting head 33 is connected to the carving knife through a quick release mechanism;

[0034] The driving mechanism includes a worm wheel and a worm that are rotatably arranged in the internal cavity of the substrate 1. The worm wheel is fixedly connected to a rotating table 4 that passes through the upper end of the internal cavity of the substrate 1. The left side of the worm wheel is engaged with the worm. The cylindrical section of the worm passes through the front end of the internal cavity of the substrate 1 and is fixedly connected to an external operating block 3.

[0035] The beneficial effects of the above technical solution are:

[0036] The fixed shell 5 can accommodate the movable mechanism, the connecting head and the chisel connected thereto, and different types of chisels can be placed in the fixed shell 5. The setting of the quick-release mechanism facilitates the quick connection of the connecting head 33 with different types of chisels, thereby achieving the purpose of quickly switching chisels. When switching chisels, the chisel to be used is taken out from the fixed shell 5, and the replaced chisel is put back into the fixed shell 5, thereby preventing the unused chisel from being exposed to the outside world and causing accidental injury to the engraver, and solving the technical problem that the unused engraving pen is exposed to the outside world and easily causes accidental injury to the engraver, and has low safety. The setting of the movable mechanism enables the chisel connected to the connecting head to move freely in three-dimensional space, thereby facilitating the engraver to drive the chisel to move to different positions of the purple clay teapot for engraving. The setting of the driving mechanism can drive the worm to rotate when the operating block 3 is rotated, and the worm drives the worm wheel to rotate, and the worm wheel The rotating table 4 is driven to rotate. After the positioning mechanism fixes the purple clay teapot to be engraved on the rotating table 4, the purple clay teapot can be driven to rotate, so that different positions of the purple clay teapot can be engraved when the position of the engraver remains unchanged. The positioning mechanism is used to fix the purple clay teapot on the rotating table 4. When the engraver is engraving the purple clay teapot, there is no need for the engraver to use one hand to fix the purple clay teapot, which saves manpower. If the engraver is accustomed to using one hand to fix the purple clay teapot, the positioning mechanism can also play an auxiliary fixing role. When the engraver fails to fix the purple clay teapot due to negligence, the purple clay teapot can still remain in a fixed state. This solves the technical problem that if the engraver manually positions the teapot, it is easy for the engraver to fail to fix the purple clay teapot due to negligence during engraving, causing the purple clay teapot to shake, affecting the engraving effect of the purple clay teapot, and even causing the engraving to fail.

[0038] A plurality of sliding holes 20 are arranged circumferentially on one side of the positioning arc block 15 away from the positioning arc block 1 8, and the plurality of sliding holes 20 are slidably connected with the plurality of sliding sleeves 16 in a one-to-one correspondence. A suction cup 9 is provided at one end of the sliding sleeve 16 close to the center of the rotating table 4, and a suction sleeve 17 is slidably provided in the internal through hole of the sliding sleeve 16, and the internal through hole of the sliding sleeve 16 is communicated with the suction cup 9, and the suction sleeve 17 is fixedly connected to the positioning arc block 15 through a fixing plate 18, and a suction hole is provided at one end of the suction sleeve 17 close to the suction cup 9, and the suction hole is communicated with the suction cup 9, and a sealing block 26 is slidably provided in the suction hole, and the sealing block 26 is fixed at one end away from the suction cup 9 A connecting block 24 is connected, and the connecting block 24 passes through the end of the suction hole away from the suction cup 9 and enters the groove 25 and is rotatably connected to the sliding shaft 36. The groove 25 is set at the end of the suction sleeve 17 away from the suction cup 9. A connecting shaft is rotatably arranged in the groove 25. The connecting shaft is fixedly connected to the elliptical block 21. A torsion spring is fixedly arranged between the elliptical block 21 and the groove 25. The torsion spring sleeve is arranged on the connecting shaft. The sliding shaft 36 is slidably connected to the arc groove 22 arranged in the middle part of the elliptical block 21. The left and right ends of the short part of the elliptical block 21 are respectively provided with limit blocks 23, and the limit blocks 23 are in contact with the internal through holes of the sliding sleeve 16 correspondingly.

[0039] A plurality of matching blocks 1 and a plurality of pushing blocks 59 are circumferentially arranged at the lower end of the side of the positioning arc plate 2 12 away from the positioning arc plate 10. The pushing block 59 is arranged on the side away from the suction cup 9, and the matching block 1 is arranged on the side close to the suction cup 9. The lower inclined ends of the matching blocks 1 are slidably connected with the upper inclined ends of the matching blocks 2 19 in a one-to-one correspondence. The matching blocks 2 19 are slidably connected with the sliding grooves 60 in a one-to-one correspondence, and a spring 2 is fixed between the matching blocks 2 19 and the sliding grooves 60. The sliding grooves 60 are arranged in a one-to-one correspondence with the sliding sleeves 16, and the sliding grooves 60 are arranged at the upper end of the sliding sleeves 16. The pushing blocks 59 are correspondingly arranged on the upper side of the arc grooves 22 in the middle of the elliptical blocks 21.

[0040] The beneficial effects of the above technical solution are:

[0041] When the positioning mechanism fixes the purple clay teapot to be engraved on the rotating table 4, the positioning arc plate 10 is first pulled upward by the operating rod 11, and the positioning arc plate 10 drives the positioning arc plates 2 12 on the front and rear sides to move upward, and a plurality of springs 13 are stretched. At this time, the state of the positioning mechanism is as follows: Figure 4As shown, in this process, the positioning arc plate 10 slides up and down along the positioning arc block 18, and the positioning arc plate 2 12 slides up and down along the positioning arc block 2 15, so that the sliding of the positioning arc plate 10 and the positioning arc plate 2 12 has a guiding effect, and then the purple clay teapot to be carved is placed in the central area of ​​the rotating table 4, and the operating rod 11 is released. Under the elastic action of the spring 13, the positioning arc plate 2 12 and the positioning arc plate 10 on the front and rear sides move downward to restore to their original positions. When the positioning arc plate 2 12 on the front and rear sides moves downward, it drives a plurality of matching blocks 1 and a plurality of pushing blocks 59 to move downward. When the matching block 1 moves downward, it slides along the inclined end of the matching block 2 19, thereby pushing the sliding sleeve 16 to move toward the center direction of the rotating table 4 through the matching block 2 19, and the sliding hole 20 guides the movement of the sliding sleeve 16, and the sliding sleeve 16 drives the suction cup 9 to move toward the center direction of the rotating table 4, and the front and rear sides are moved downward. The simultaneous downward movement of the positioning arc plates 12 on both sides can drive the plurality of suction cups 9 to move toward the center direction of the rotating platform 4 at the same time. The number of the plurality of suction cups 9 is greater than three, so that the purple clay teapot can be pushed to move after the suction cups 9 contact the purple clay teapot. After the plurality of suction cups 9 contact the purple clay teapot, the purple clay teapot will be pushed to the center of the rotating platform 4. Then the engraver assists in pressing the purple clay teapot to keep the purple clay teapot still. As the plurality of suction cups 9 continue to move and are adsorbed and connected to the purple clay teapot, a closed negative pressure space is formed between the suction cups 9 and the purple clay teapot until the suction cups 9 cannot move. At this time, the negative pressure between the suction cups 9 and the purple clay teapot is small, so that the engraver can easily pull the purple clay teapot away from the suction cups 9 without causing damage to the purple clay teapot. After the suction cups 9 cannot move, the sliding sleeve 16 cannot move. At this time, the matching block 1 will press the matching block 2 19 to slide toward the sliding groove 60, and the spring 2 is compressed to ensure the normal downward movement of the positioning arc plate 2 12.

[0042] After the sliding sleeve 16 moves toward the center of the rotating table 4, the through hole inside it is disconnected from the groove 25. At this time, the short part of the elliptical block 21 is distributed in the up-down direction. Figure 7As shown, the limit block 23 is out of contact with the internal through hole of the sliding sleeve 16. At this time, the elliptical block 21 can rotate freely in the groove 25, and the limit block 23 will not contact the end of the groove 25 connected to the connecting block 24 during the rotation of the elliptical block 21. When the limit block 23 contacts the internal through hole of the sliding sleeve 16, the elliptical block 21 cannot rotate, so that the elliptical block 21 can only rotate under the influence of the pushing block 59, thereby improving the ability of the elliptical block 21 and the sealing block 26 connected thereto to resist external influences. After the suction cup 9 cannot move, as the positioning arc plate 21 continues to move downward, the pushing block 59 begins to contact the arc groove 22, driving the elliptical block 21 to rotate downward. In this process, the elliptical block 21 drives the torsion spring to deform, and the long part of the elliptical block 21 is distributed in the up and down directions. At this time, the sliding shaft 36 slides along the arc groove 22 to drive the connecting block 24 to move in the direction away from the suction cup 9, and the connecting block 24 drives the sealing block 26 to move in the direction away from the suction cup 9, so that the suction cup 9 is 9 becomes larger, thereby increasing the volume of the enclosed negative pressure space formed between the suction cup 9 and the purple clay teapot, and increasing the negative pressure between the suction cup 9 and the purple clay teapot, thereby improving the connection stability between the suction cup 9 and the purple clay teapot. At this time, it is difficult for the engraver to pull the purple clay teapot away from the suction cup 9, and the suction cup 9 is made of elastically deformable material to avoid rigid contact between the suction cup 9 and the purple clay teapot, which causes wear to the purple clay teapot. During the downward movement of the positioning arc plate 2 12 on the front and rear sides, the sum of the elastic forces of the plurality of springs 13 is always greater than the sum of the elastic forces of the torsion springs connected to the plurality of elliptical blocks 21 and the plurality of springs 2 connected to the matching blocks 2 19, until the negative pressure between the suction cup 9 and the purple clay teapot is large enough, and the purple clay teapot will not be damaged under the negative pressure. At this time, the positioning arc plate 2 12 cannot push the elliptical block 21 to continue rotating through the pushing block 59, and the positioning arc plate 2 12 stops moving, completing the purpose of the positioning mechanism fixing the purple clay teapot on the rotating table 4. The positioning mechanism can be suitable for fixing purple clay teapots of different diameters.

[0043] When the positioning arc plate 2 12 moves upward along with the positioning arc plate 1 10, the matching block 2 19 and the matching block 1 move upward synchronously under the elastic action of the spring 2, and at the same time, the push block 59 is out of contact with the arc groove 22, and the elliptical block 21 gradually returns to its original position under the elastic action of the torsion spring. During this process, the sealing block 26 moves toward the direction close to the suction cup 9. At this time, the negative pressure between the suction cup 9 and the purple clay teapot gradually decreases until the inclined end of the matching block 1 starts to slide along the inclined end of the matching block 2 19. The engraver pulls the purple clay teapot away from the suction cup 9, and the matching block 1 moves upward along with the positioning arc plate 2 12, driving the matching block 2 19 to move away from the center of the rotating table 4, and the matching block 2 19 drives the sliding sleeve 16 and the suction cup 9 to move away from the center of the rotating table 4, and returns to the above-mentioned state. Figure 4As shown in the state of the positioning mechanism, the setting of the positioning mechanism partially blocks the purple clay teapot. Therefore, after the unblocked part of the purple clay teapot is carved, it is necessary to drive the positioning arc plate 2 12 upward again to make the positioning mechanism release the purple clay teapot and adjust the position of the purple clay teapot. Then the positioning mechanism is controlled to fix the purple clay teapot. The front and rear sides of the arc groove are respectively slidably provided with positioning arc blocks 2 15. By driving the positioning arc blocks 2 15 to slide along the arc groove, the position of the positioning arc blocks 2 15 and the suction cup 9 connected thereto can be adjusted according to the carving situation. At this time, the positioning arc plate 10 slides along the lower end of the positioning arc plate 2 12, which can reduce the blocking area of ​​the purple clay teapot by the positioning mechanism, and complete the carving of the purple clay teapot while reducing the number of times the positioning mechanism is operated to fix the purple clay teapot.

The guide arc blocks 51 are slidably connected one by one, and a plurality of guide arc blocks 51 are evenly arranged in the guide hole in the circumferential direction. The guide hole is set at one end of the guide sleeve 40 close to the center of the rotating table 4, and the end of the guide sleeve 40 away from the center of the rotating table 4 is fixedly connected to the bevel gear 2 48, and the bevel gear 2 48 is rotatably connected to the mounting head 35, and the bevel gear 2 48 is meshed with the bevel gear 1 47. A clamping block 54 is correspondingly provided between adjacent meshing teeth of the bevel gear 2 48, and the clamping block 54 is slidably provided in the clamping groove 58, and a spring 57 is fixedly provided between the clamping block 54 and the clamping groove 58, and the clamping groove 58 is provided outside the mounting head 35;

[0050] The bevel gear 1 47 is fixedly connected to the control sleeve 52, and the control sleeve 52 is rotatably connected to the rotating hole at the front end of the mounting head 35, and the control sleeve 52 is evenly provided with a plurality of clamping holes 1 in the circumferential direction, and the rotating hole is evenly provided with a plurality of clamping holes 2 in the circumferential direction, and the plurality of clamping holes 2 are slidably connected with the plurality of locking blocks in a one-to-one correspondence, and a spring 6 is fixedly provided between the locking block and the clamping hole 2, and the plurality of clamping holes 1 are matched with the plurality of locking blocks in a one-to-one correspondence, and the internal through hole of the control sleeve 52 is movably connected with the control shaft 53, and the control shaft 53 is evenly provided with a plurality of clamping holes 3 in the circumferential direction, and the plurality of clamping holes 3 are slidably connected with the plurality of push-off blocks 55 in a one-to-one correspondence, and a spring 7 is fixedly provided between the push-off block 55 and the clamping hole 3, and the plurality of push-off blocks 55 are matched with the plurality of clamping holes in a one-to-one correspondence, and the end of the control shaft 53 away from the control sleeve 52 is fixedly connected to the operating ring 39.

[0051] The beneficial effects of the above technical solution are:

[0052] The rotating shaft 41 can rotate along the front and rear horizontal planes of the groove 2 34, so the rotating shaft 41 can drive the mounting shell 27 to rotate along the front and rear horizontal planes, and the mounting shell 27 can drive the grinding head 38 and the mounting head 35 to rotate along the front and rear horizontal planes, so that the grinding head 38 and the mounting head 35 can move forward, backward, left and right, rotate up and down, and rotate forward and backward. The mounting head 35 can drive the carving knife to move. When switching different carving knives and removing the carving knife and the mounting head 35, first pull the clamping block 54 in the direction away from the bevel gear 2 48, and the clamping block 54 slides along the clamping groove 58, and the spring 57 is compressed until the clamping block 54 is out of contact with the bevel gear 2 48. At this time, the bevel gear 2 48 can rotate freely, and then press the operating ring 39, and the operating The operating ring 39 drives the control shaft 53 to move and rotate in the internal through hole of the control sleeve 52. The internal through hole of the control sleeve 52 is movably connected to the control shaft 53, that is, the control shaft 53 can both move and rotate in the internal through hole of the control sleeve 52. A limit ring is provided on the side of the internal through hole of the control sleeve 52 close to the operating ring 39 to prevent the control shaft 53 from being separated from the control sleeve 52 until the plurality of clamping holes three are correspondingly connected with the plurality of clamping holes one. At this time, under the elastic action of the spring seven, the push-off block 55 enters the clamping hole one, and the locking block in the clamping hole one is pushed into the clamping hole two, so that the locking block is separated from the clamping hole one, and the spring six is ​​compressed. In this process, the elastic force of the spring seven is greater than the elastic force of the spring six. At this time, the control shaft 53 and the control sleeve 52 are connected as a whole, and the control The control sleeve 52 can be rotated in the rotating hole, and then the operating ring 39 is rotated. The operating ring 39 can drive the control sleeve 52 to rotate through the control shaft 53. The control sleeve 52 drives the bevel gear 1 47 to rotate, and the bevel gear 1 47 drives the bevel gear 2 48 to rotate. The bevel gear 2 48 drives the guide sleeve 40 to rotate. When the guide sleeve 40 rotates, the guide arc block 51 drives the plurality of clamping blocks 49 to move in a direction away from each other, so that the plurality of clamping blocks 49 release the clamping fixation on the engraving knife rod, and then the engraving knife rod to be used is inserted into the mounting hole 56, and the operating ring 39 is rotated in the opposite direction. The guide sleeve 40 is rotated in the opposite direction through the control shaft 53, the control sleeve 52, the bevel gear 1 47 and the bevel gear 2 48, and the plurality of clamping blocks 49 are pushed to move in the opposite direction through the guide arc block 51. The plurality of clamping blocks 49 are moved in the direction of approaching each other, and the required engraving knife rod is clamped and fixed. The number of the plurality of clamping blocks 49 is greater than 3, and then the control shaft 53 is pulled in the front-to-back direction to disengage the push-off block 55 from the clamping hole 1. The push-off block 55 is a triangular block, and the inclined section is the front and rear sides of the push-off block 55, that is, it is inclined along the length direction of the control shaft 53. Therefore, when the control shaft 53 is pulled in the front-to-back direction, the push-off block 55 can be disengaged from the clamping hole 1. The spring 7 is compressed. At this time, the locking block re-enters the clamping hole 1 under the elastic action of the spring 6, so that the control sleeve 52 can no longer rotate in the rotating hole. Therefore, the bevel gear 1 47 and the bevel gear 2 48 cannot rotate, and the plurality of clamping blocks 49 will not move, thereby achieving the purpose of installing and fixing the engraving knife rod. Finally, the clamping block 54 is released.Under the elastic action of spring 57, the clamping block 54 moves back to between the adjacent meshing teeth of bevel gear 2 48. Even if the control shaft 53 drives the push-off block 55 to re-match with the clamping hole 1 due to the miscontrol of the operating ring 39, the bevel gear 2 48 cannot rotate, further improving the connection stability between the clamping blocks 49 and the carving knife rod;

[0053] When operating the carving knife, the carving worker holds the C-shaped handle 37 with his thumb and buckles the inner ring of the operating ring 39 with his index finger. Since the control shaft 53 is movably connected to the internal through hole of the control sleeve 52, the control shaft 53 and the operating ring 39 connected thereto can adjust the angle and the position in the front-back direction, which is convenient for the carving worker to buckle the index finger and improves the carving worker's comfort. When it is necessary to polish the purple clay teapot, the pull block 43 is pulled away from the guide sleeve 40. The pull block 43 drives the gear 1 45 to disengage from the gear 2 46 through the mounting block 44, and the spring 4 is compressed. At this time, the gear 2 46 can rotate, and then drive the C-shaped handle 37 to rotate downward with the gear 2 46 as the center, drive the mounting head 35 to rotate downward, so that the grinding head 38 correspondingly arranged between the mounting head 35 and the mounting shell 27 can contact the purple clay teapot, and then release the pull block 43. Under the elastic action of the spring 4, the pull block 43 drives the gear 1 45 and the gear 2 46 to mesh again, so that the gear 2 46 and the C-shaped handle 37 connected thereto cannot rotate. By operating the C-shaped handle 37, the mounting shell 27 is driven to move, and the mounting shell 27 drives the grinding head 38 to move. The quick-release mechanism of the present invention can quickly switch the carving knife, and the grinding head 38 is arranged between the mounting head 35 and the mounting shell 27, which not only saves space but also makes the grinding work and the carving work independent of each other. The carving personnel only need to operate the operating ring 39 and the clamping block 54 to disassemble and install the carving knife, and only need to control the pulling block 43 and the C-shaped handle 37 to switch between the grinding work and the carving work. The operation is simple and convenient. Compared with CN2022 10121456 - A workbench for engraving purple clay teapots discloses a grinding connector and a hand support rod which are symmetrically distributed on both sides of a base, so that the grinding connector and the engraving pen are relatively arranged, and the grinding connector and the engraving pen need to be operated at different positions. The arrangement of the grinding head 38 of the present invention is more convenient for the engraver to operate. If the grinding connector in the application document can automatically grind the purple clay teapot, compared with the engraver of the present invention manually controlling the grinding head 38 to grind the purple clay teapot, due to the complexity of engraving, the automatic grinding is inferior to the manual grinding.

[0054] Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include these modifications and variations.
