As shown in fig. 1 to 3, the present embodiment provides a jig for use in a denture processing apparatus to fix a denture processing blank 100. The fixture comprises a base 1, a pressing plate 2 and a shaft gear 3, wherein the base 1 is used for containing a blank 100, the pressing plate 2 is used for pressing the blank 100 on the base 1, and the shaft gear 3 is used for fixing the pressing plate 2 on the base 1. Specifically, the base 1 is provided with a stepped hole 11 for accommodating the blank 100, and is also provided with a threaded hole 12. The pressing plate 2 is rotatably disposed above the base 1, as shown in fig. 4, the pressing plate 2 includes a pressing portion 21 and a transmission portion 22, the pressing portion 21 can be pressed on the blank 100, a dismounting hole 211 and a chute 212 which are communicated with each other are formed in the pressing portion 21, and an inner gear ring 221 is disposed on the transmission portion 22. As shown in fig. 5, the shaft gear 3 includes a tooth portion 31 and a screw portion 32, the tooth portion 31 is engaged with the ring gear 221, the diameter of the circumscribed circle of the tooth portion 31 is smaller than the diameter of the attachment/detachment hole 211, and the screw portion 32 passes through the attachment/detachment hole 211 to be engaged with the screw hole 12.

The use process of the clamp provided by the embodiment is as follows: firstly, screwing a threaded part 32 into a part of a threaded hole 12 in advance, then placing a blank 100 into a stepped hole 11, then placing a pressing plate 2 above the blank 100, enabling a tooth part 31 of a shaft gear 3 to penetrate through a disassembly and assembly hole 211 to be meshed with an inner gear ring 221, ensuring that the lower end face of the tooth part 31 is higher than the top face of a material pressing part 21, then rotating the pressing plate 2, enabling the inner gear ring 221 to drive the tooth part 31 of the shaft gear 3 to rotate, enabling the threaded part 32 to relatively move into a sliding groove 212 through the disassembly and assembly hole 211, and simultaneously enabling the threaded part 32 to continuously screw downwards into the threaded hole 12 until the lower end face of the tooth part 31 is bonded with and pressed against the top face of the material pressing part 21, so that the pressing plate 2 presses the blank 100 into a base 1, and fixing the blank 100 is realized; when the material is required to be replaced, the pressing plate 2 is reversely rotated, the tooth part 31 is reversely rotated, the thread part 32 is relatively moved into the dismounting hole 211, but the matching relation between the thread part 32 and the threaded hole 12 which are screwed in advance is remained, then the pressing plate 2 is taken down, the processed blank 100 is taken down, a new blank 100 is replaced, and then the pressing plate 2 is directly pressed on the new blank 100, so that the dismounting of the shaft gear 3 is not required.

On one hand, the clamp provided by the embodiment is characterized in that the threaded hole 12 is formed in the base 1, the annular gear 221, the dismounting hole 211 and the sliding groove 212 are formed in the pressing plate 2, the tooth part 31 and the thread part 32 are formed in the shaft gear 3, the thread part 32 is screwed into one part of the threaded hole 12 of the base 1 in advance, and then the tooth part 31 is meshed with the annular gear 221 through rotating the pressing plate 2 and drives the thread part 32 to be continuously screwed into the threaded hole 12, so that the blank 100 can be fixed, the operation is simple, and the use is convenient; on the other hand, by setting the diameter of the circumscribed circle of the tooth portion 31 to be smaller than the diameter of the dismounting hole 211, the pressing plate 2 can be directly removed from the base 1 during material changing, and the shaft gear 3 does not need to be detached from the base 1, namely, the threaded portion 32 of the shaft gear 3 can always keep a pre-screwed matching relationship with the threaded hole 12 of the base 1 during material changing, and only the pressing plate 2 needs to be removed, so that the dismounting process is greatly simplified, and the production efficiency is improved.

Preferably, at least two shaft gears 3 are uniformly distributed along the circumferential direction of the nip portion 21. The shaft gear 3 is arranged in such a way to be beneficial to ensuring that the circumferential stress of the material pressing part 21 is uniform, thereby ensuring that the circumferential direction of the blank 100 can be stably fixed. In addition, when the plurality of shaft gears 3 are provided, the ring gear 221 can simultaneously drive the plurality of shaft gears 3 to rotate, thereby remarkably saving the disassembly and assembly time. As shown in fig. 2, in the present embodiment, three shaft gears 3 are uniformly distributed on the circumference of the nip portion 21. Further, in order to save the processing time of the tooth form, when a plurality of shaft gears 3 are provided, a plurality of ring gears 221 engaged with the tooth portions 31 are separately provided on the transmission portion 22. Of course, in other embodiments, the transmission portion 22 may be provided with a full ring gear 221. The tooth 31 has the same modulus as the ring gear 221.

As shown in fig. 2 and 3, the fixture provided in this embodiment further includes a retainer 4 having a shaft hole 41 formed therein, and the shaft gear 3 further includes an upper shaft portion 33, the upper shaft portion 33 being rotatably inserted into the shaft hole 41. The cage 4 is advantageous in ensuring the stability of the operation of the shaft gear 3, effectively preventing the screw portion 32 of the shaft gear 3 from being completely unscrewed from the screw hole 12. Further, the jig further includes a bearing 5, and the upper shaft portion 33 is rotatably inserted into the shaft hole 41 through the bearing 5, the bearing 5 being advantageous in ensuring smoothness of rotation. Preferably, the bearing 5 is a self-lubricating bearing.

In order to prevent dust generated during the processing of the blank 100 from affecting the engagement of the tooth portion 31 and the ring gear 221, as shown in fig. 1 and 3, the clamp provided in this embodiment further includes a dust cover 6, which is covered on the pressing plate 2. Optionally, the dust cover 6 is provided with a buckling edge 61, and the pressing plate 2 is provided with a buckling table 223 matched with the buckling edge 61. The sealing performance between the dust cover 6 and the pressing plate 2 can be ensured through the matching of the buckling edge 61 and the buckling table 223, so that a good dust-proof effect is achieved. In addition, it should be noted that the dust cover 6 is rotatably disposed on the platen 2, so as to ensure that the dust cover 6 can rotate relative to the platen 2 when the platen 2 rotates.

Further, as shown in fig. 1 and 3, the dust cap 6 is connected to the holder 4 by a fastener 7. When the platen 2 rotates, the dust cap 6 and the holder 4 do not rotate together with the platen 2.

Preferably, in this embodiment, the fixture further includes a wrench 8, as shown in fig. 4, a driving hole 222 is provided on an outer sidewall of the transmission part 22, and the wrench 8 can be inserted into the driving hole 222. The pressing plate 2 can be rotated conveniently through the matching of the wrench 8 and the driving hole 222, so that time and labor are saved. It should be noted that, in order to ensure the service life of the fixture, the rotation angle of the wrench 8 is less than or equal to the arc angle of the chute 212 on the platen 2. Further, the base 1 is provided with a cutter placing hole 13, so that the cutter can be replaced conveniently in the processing process.

The embodiment also provides denture processing equipment, which comprises the fixture. The false tooth processing equipment provided by the embodiment simplifies the disassembly and assembly process during material changing by adopting the clamp, is convenient to operate and has high working efficiency.
