The inclined groove, square groove, and adjusting block that fit with it will move downward along the insertion slot, thereby driving the rack to move. The rack can drive the gear to rotate, causing the clamping plate to rotate away from the locking slot. During this process, the torsion spring accumulates elastic potential energy. Finally, the clamping plate is pushed out of the locking slot. At this time, the insertion rod and the tool can be pushed out of the mounting sleeve.

[0020] After inserting the new tool into the insertion slot, reverse-rotate the threaded rod, which drives the triangular plate to move towards the side close to the threaded sleeve. The elastic potential energy stored in the torsion spring pushes the adjusting block to move upwards. Finally, the clamping plate is inserted into the locking slot, and the relative positions of the insertion rod, the tool, and the mounting sleeve are fixed. Only the forming tool bit and the insertion rod in the tool need to be replaced, and there are fewer supporting components together with the forming tool bit, resulting in lower costs. At the same time, the insertion rod in the tool is inserted into the inner side of the insertion slot in the mounting sleeve, and then the two locking slots are clamped by the two clamping plates. Compared with the bolt fixation method, the fixation is more firm, and no equipment such as a pistol drill is required during loading and unloading, reducing the difficulty of loading and unloading.

[0021] Second, the angle adjustment driving component of the present utility model can pull the tool bit angle adjustment plate to rotate around the connecting shaft on the vertical plate, adjust the angle of the tool, adjust the angle and depth of the tool in the mold. The distance adjustment driving component cooperates with components such as the lead screw to adjust the left and right positions of the tool in the mold. Used in conjunction with the angle adjustment driving component, the parameters such as the angle, position, and depth of the tool can be flexibly adjusted, and the degree of freedom of adjustment is higher.

[0029] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0030] Referring to Figures 1-4 , a ceramic turning machine that facilitates tool replacement, including a machine body 1, a mold 2, a tool 3, and a mounting sleeve 4. When producing the embryo body of ceramics, most circular ceramics are formed by a turning machine. Generally, the process is as follows: the clay raw material is put into the mold 2, and the mold 2 itself is connected to a motor for driving its rotation. The tool 3 abuts against the clay raw material and extrudes the clay raw material into a suitable shape. Since different ceramic shapes are produced, different molds 2 and different tools 3 are required. Therefore, the tool 3 needs to be replaced as needed.

[0031] Furthermore, the insertion rod 302 cooperates with the insertion slot in the mounting sleeve 4. A blocking plate 402 is arranged in the insertion slot. Two connecting plates 403 are arranged on the blocking plate 402 and are symmetrically distributed with respect to the center line of the blocking plate 402. A connecting slot for cooperating with the connecting plate 403 is arranged at the head of the insertion rod 302. When the insertion rod 302 is inserted into the insertion slot, the connecting plate 403 in the blocking plate 402 is inserted into the inside of the insertion rod 302. The insertion rod 302 is connected to a circular plate, and the size of the circular plate is larger than that of the insertion rod 302. When the insertion rod 302 is inserted into the deepest part of the insertion slot, the circular plate abuts against the outer wall of the mounting sleeve 4;

[0032] Specifically, a clamping plate 401 is arranged in the mounting sleeve 4. One end of the clamping plate 401 is provided with a locking plate. A locking groove 303 is arranged at the position of the insertion rod 302 corresponding to the locking plate in the clamping plate 401. A rotating shaft penetrates through the end of the clamping plate 401 far from the locking plate, and the rotating shaft is inserted into the adjusting bracket 404. The rotating shaft is connected to a torsion spring. Refer to Figure 3 , the torsion spring gives the rotating shaft, the clamping plate 401, and the locking plate a force to rotate towards the side close to the insertion rod 302, so that the connection between the locking plate and the locking groove 303 is tighter. Moreover, when the rack 405 moves upward, the force given by the torsion spring can make the clamping plate 401 rotate towards the side close to the insertion rod 302. It should be noted that two clamping plates 401 are provided, and the two clamping plates 401 are symmetrically distributed with respect to the center line of the adjusting bracket 404. Two locking grooves 303 are arranged on the insertion rod 302 corresponding to the two clamping plates 401.

[0033] Further, the rotating shaft is connected to the gear 406. The gear 406 is connected to the rack 405 through gear meshing transmission. The rack 405 is connected to an adjusting mechanism for adjusting its depth in the insertion slot. It should be noted that there are two racks 405, and the two racks 405 are symmetrically distributed. The two racks 405 are connected by an intermediate plate. The adjusting mechanism drives the rack 405 to move along the inner wall of the insertion slot to adjust its depth, thereby driving the gear 406 and the rotating shaft to rotate. As Figure 3 shown, the adjusting mechanism drives the rack 405 to move downward, driving the gear 406 and the rotating shaft to rotate. The clamping plate 401 rotates together with the rotating shaft and is received into the groove in the mounting sleeve 4. At this time, the insertion rod 302 can be withdrawn from the mounting sleeve 4. A new insertion rod 302 and the forming cutter head 301 are inserted into the insertion slot. When the rack 405 moves upward, the rotating shaft and the clamping plate 401 can be rotated toward the insertion rod 302 side, and the locking plate in the insertion rod 302 is inserted into the locking slot 303;

[0034] Specifically, the adjusting mechanism includes an adjusting block 407. The outer wall of the adjusting block 407 fits against the inner wall of the insertion slot. A square groove is provided in the adjusting block 407. The square groove is connected to an inclined groove. The inclined surface of the inclined groove fits against the hypotenuse of the triangular plate 408. The triangular plate 408 fits against the inner wall of the guiding groove in the mounting sleeve 4. A threaded rod 409 is inserted into the triangular plate 408. The threaded rod 409 is threadedly connected to a threaded sleeve. The threaded sleeve is provided on the outer wall of the mounting sleeve 4. And one end of the threaded rod 409 passing through the outer wall of the mounting sleeve 4 is installed with a handle provided with anti-slip threads.

[0035] Furthermore, the mounting sleeve 4 is connected to a cutter head angle adjustment plate 5. The cutter head angle adjustment plate 5 is arranged in a Z shape, and the middle part of the cutter head angle adjustment plate 5 is connected to a vertical plate. The end of the cutter head angle adjustment plate 5 away from the mounting sleeve 4 is connected to an angle adjustment driving component 6. Refer to Figure 1 、 Figure 2 . The angle adjustment driving component 6 can pull the cutter head angle adjustment plate 5 to rotate around the connecting shaft on the vertical plate to adjust the angle of the cutter 3 and adjust the angle and depth of the cutter 3 in the mold 2;

[0036] It should be noted that the vertical plate is connected to a distance adjustment plate 7. The distance adjustment plate 7 is connected to two parallel tracks. The tracks are arranged on the machine body 1. The distance adjustment plate 7 is connected to an auxiliary plate 8 through two cross bars. The auxiliary plate 8 cooperates with the tracks. One end of the angle adjustment driving component 6 away from the cutter head angle adjustment plate 5 is arranged on the auxiliary plate 8. And the distance adjustment plate 7 is threadedly connected to a lead screw. The lead screw is connected to a distance adjustment driving component 9 for driving its forward and reverse rotation. The distance adjustment driving component 9 cooperates with the lead screw and other components to adjust the left and right position of the cutter 3 in the mold 2. Used in conjunction with the angle adjustment driving component 6, the cutter 3 can be sent into the mold 2 to process the clay and pushed away from the mold 2, so that the clay feeding and the blanking of the embryo are both more convenient.

[0037] Working principle:

[0038] The cutting tool 3 is detachably connected to the mounting sleeve 4. The relative position between the cutting tool 3 and the mold 2 can be adjusted through components such as the tool head angle adjustment plate 5 and the angle adjustment driving component 6. The cutting tool 3 can extrude the clay to make the clay have the same shape as the mold 2, forming a ceramic embryo;

[0039] When the cutting tool 3 needs to be replaced, first rotate the threaded rod 409, which can drive the triangular plate 408 to move away from the threaded sleeve. The hypotenuse of the triangular plate 408 fits with the inclined surface in the inclined groove. As the triangular plate 408 moves, the inclined groove, square groove, and adjusting block 407 that fit with it will move downward along the insertion groove, thereby driving the rack 405 to move. The rack 405 can drive the gear 406 to rotate, causing the clamping plate 401 to rotate away from the locking groove 303. During this process, the torsion spring accumulates elastic potential energy. Finally, the clamping plate 401 is pushed out of the locking groove 303, and at this time, the insertion rod 302 and the cutting tool 3 can be pushed out of the mounting sleeve 4;

[0040] After that, insert the new cutting tool 3 into the insertion groove. Then rotate the threaded rod 409 in the reverse direction, which drives the triangular plate 408 to move closer to the threaded sleeve. The elastic potential energy accumulated by the torsion spring pushes the adjusting block 407 to move upward. Finally, the clamping plate 401 is inserted into the locking groove 303, and the relative positions of the insertion rod 302, the cutting tool 3, and the mounting sleeve 4 are fixed.

[0041] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
