Description

Technical Field

[0001] The present application relates to the technical field of denture processing, and in particular to a denture loading and unloading fixture. Background Art

[0002] Dentures are what people commonly call "false teeth", just like "false legs" and "false limbs" are called "artificial limbs". "Dentures" mean teeth that fulfill their "duties" for humans. In medicine, it is a general term for restorations made after partial or complete loss of upper and lower teeth.

[0003] During the processing and production of denture blocks, the automatic loading and unloading mechanism of the denture blocks also needs to use a clamp to hold the denture blocks, load the denture blocks into the processing machine, and after the clamp of the processing machine clamps the denture blocks to be processed, the automatic loading and unloading mechanism releases the clamp and leaves the processing machine, and the processing machine starts processing. After the processing machine completes the processing task, the automatic loading and unloading mechanism enters the processing bin of the processing machine, clamps the denture blocks, and then the clamp of the processing machine releases the clamp, and the automatic loading and unloading mechanism removes the processed workpiece. Therefore, there is an urgent need for a clamp that can realize automatic loading and unloading of denture blocks to cooperate with the automatic loading and unloading mechanism and the processing machine.

[0004] At present, the loading and unloading fixtures of the denture blocks in the related art are easy to slip, which affects the processing accuracy, has poor stability, and is not convenient for clamping by the automatic loading and unloading mechanism, thereby affecting the processing efficiency of the denture blocks. Utility Model Content

[0005] The purpose of this application is to provide a denture loading and unloading fixture to solve the problems existing in the above-mentioned prior art.

[0006] To achieve the above purpose, the technical solution adopted in this application is:

[0007] A denture loading and unloading fixture, comprising:

[0008] A first polygonal clamping portion, used to be clamped by a clamp of a processing machine; and

[0009] The second polygonal clamping portion is used to be clamped by a manipulator of the automatic loading and unloading mechanism;

[0010] Wherein, the side surface of the second polygonal clamping part has at least a pair of mutually parallel clamping grooves; one end of the second polygonal clamping part is fixedly connected to the first polygonal clamping part, and the other end is connected to the denture material block.

[0011] In a possible implementation, the first polygonal clamping portion is one of a regular triangle column, a regular quadrilateral column, a regular pentagonal column, a regular hexagonal column, a regular heptagonal column, and a regular octagonal column, and the first polygonal clamping portion has a chamfered transition portion at one end away from the second polygonal clamping portion.

[0012] In a possible implementation, the second polygonal clamping portion is a quadrilateral block, and both sides or four sides of the second polygonal clamping portion have clamping grooves.

[0013] In a possible implementation, one end of the second polygonal clamping portion away from the first polygonal clamping portion is connected to the denture block by bonding.

[0014] In a possible implementation, the card slot is a V-shaped card slot.

[0015] The beneficial effects of the technical solution provided by this application include at least:

[0016] The denture loading and unloading fixture of the present application has two clamping positions, namely a first polygonal clamping part and a second polygonal clamping part. The first polygonal clamping part is used to be clamped by the clamp of the processing mother machine, and the second polygonal clamping part is used to be clamped by the manipulator of the automatic loading and unloading mechanism. The double clamping position design can reduce the requirements for the placement accuracy of the denture material block and the requirements for the feeding position accuracy of the automatic loading and unloading mechanism, and has stronger adaptability; and, the two clamping positions adopt a polygonal structure to ensure that the denture material block will not fall off or slide during the loading and unloading and processing process, with high processing accuracy, strong stability, and easy clamping by the automatic loading and unloading mechanism, thereby improving the processing efficiency of the denture material block; in addition, the second polygonal clamping part is connected to the denture material block by bonding, so that the denture loading and unloading fixture can be reused to reduce costs.

[0020] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

It should be noted that the words "front", "rear", "left", "right", "up" and "down" used in the following description refer to the directions in the drawings of the present application specification, and the words "bottom surface" and "top surface", "inside" and "outside" refer to the direction towards or away from a specific component, respectively. In addition, the terms "first" and "second" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present application specification, the meaning of "multiple" is two or more.

[0022] The present application is further described below in conjunction with the accompanying drawings and embodiments.

[0023] Figure 1 A structural schematic diagram of a denture loading and unloading fixture provided by an exemplary embodiment of the present application is shown, wherein the denture loading and unloading fixture comprises a first polygonal clamping portion 1 and a second polygonal clamping portion 2, wherein the side surface of the second polygonal clamping portion 2 has at least a pair of mutually parallel grooves 21; one end of the second polygonal clamping portion 2 is fixedly connected to the first polygonal clamping portion 1, and the other end is connected to the denture material block 3.

[0024] In detail, the first polygonal clamping portion 1 is one of a regular triangular column, a regular quadrilateral column, a regular pentagonal column, a regular hexagonal column, a regular heptagonal column, and a regular octagonal column (the figure schematically shows the case of a regular hexagonal column), and the end of the first polygonal clamping portion 1 away from the second polygonal clamping portion 2 has a chamfered transition portion 11 for easy clamping.

[0025] Further, the second polygonal clamping portion 2 is a quadrilateral block, and both sides or four sides of the second polygonal clamping portion 2 are provided with a clamping groove 21. Preferably, the clamping groove 21 is a V-shaped clamping groove, which can improve the clamping stability.

[0026] Furthermore, the end of the second polygonal clamping part 2 away from the first polygonal clamping part 1 is connected to the denture block 3 by bonding. As a supplementary explanation, the second polygonal clamping part 2 and the denture block 3 can be separated by heating after processing.

[0027] Next, the working principle of the denture loading and unloading fixture involved in the embodiment of the present application is explained.

[0028] Figure 2 A schematic diagram of the clamping state of the denture loading and unloading fixture provided by an exemplary embodiment of the present application is shown, wherein the first polygonal clamping portion 1 is used to be clamped by the spindle clamp 4 of the machining machine, and the shape of the clamping portion of the spindle clamp 4 of the machining machine is adapted to the first polygonal clamping portion 1; the second polygonal clamping portion 2 is used to be clamped by the manipulator 5 of the automatic loading and unloading mechanism, and the clamping end of the manipulator 5 of the automatic loading and unloading mechanism is adapted to the slot 21.

[0029] When in working state, the manipulator 5 of the automatic loading and unloading mechanism clamps the slot 21 of the second polygonal clamping part 2 and transfers it to the processing chamber of the processing machine, so that the spindle clamp 4 of the processing machine clamps the first polygonal clamp 1, and the manipulator 5 of the automatic loading and unloading mechanism is released and moved out of the processing chamber of the processing machine. After the processing of the denture block 3 is completed, the manipulator 5 of the automatic loading and unloading mechanism enters the processing chamber of the processing machine to clamp the slot 21 of the second polygonal clamp 2, and the spindle clamp 4 of the processing machine releases the first polygonal clamp 1, and the manipulator 5 of the automatic loading and unloading mechanism moves the processed denture block 3 out of the processing chamber of the processing machine, and places the processed denture block 3 in the completed processing material area.

[0030] It is worth mentioning that the processing mother machine is a CNC machine tool.

[0031] To summarize, the denture loading and unloading fixture of the present application has two clamping positions, namely a first polygonal clamping part and a second polygonal clamping part. The first polygonal clamping part is used to be clamped by the clamp of the processing mother machine, and the second polygonal clamping part is used to be clamped by the manipulator of the automatic loading and unloading mechanism. The double clamping position design can reduce the requirements for the placement accuracy of the denture material block and the requirements for the feeding position accuracy of the automatic loading and unloading mechanism, and has stronger adaptability; and, the two clamping positions adopt a polygonal structure to ensure that the denture material block will not fall off or slide during the loading and unloading and processing process, with high processing accuracy, strong stability, and easy clamping by the automatic loading and unloading mechanism, thereby improving the processing efficiency of the denture material block; in addition, the second polygonal clamping part is connected to the denture material block by bonding, so that the denture loading and unloading fixture can be reused to reduce costs.
