Description

Technical Field

[0001] The utility model relates to the technical field of dentistry, in particular to a reverse clamping fixture for a cutting machine. Background Art

[0002] At present, almost all dental abutment four-axis cutting machines on the market are based on the abutment design data, and digitally process the cuttable abutment columns to produce personalized abutments. The overall production process is: 1. Personalized abutment design; 2. Upload the design data to the cutting machine layout software for layout, and calculate and generate the tool path file; 3. Install the cuttable abutment column in the corresponding clamping position of the cutting machine fixture according to the layout position; 4. Upload the layout tool path file, and the cutting machine will automatically process the abutment column according to the tool path file; 5. Remove the cut abutment column, manually cut off the connecting rod and manually grind and adjust the shape. After grinding, the personalized abutment product is obtained.

[0003] Since the clamping holes on the cutting machine fixture are designed based on the clamping abutment column, the shape of the clamping holes can only match the interface at the tail end of the abutment column, so it is impossible to clamp other types of consumables such as ground abutments and finished abutments. For these products, the factory can only let technicians perform manual grinding production. However, the number of finished abutments and ground abutment restoration cases may account for more than 50% of the abutment shipments of the processing plant, which will cause great production pressure on the denture processing plant. Therefore, it is necessary to invent a fixture to realize the digital processing of finished abutments and ground abutments. Utility Model Content

[0004] 1. Technical issues to be solved

[0005] In view of the deficiencies in the prior art, the utility model provides a cutting machine reverse clamp, which has the advantages of reducing the working pressure of the denture processing plant, shortening the shipping process and shipping cycle, etc., and solves the problem that the traditional cutting machine clamp has a single clamping method, which results in the factory only being able to use four-axis abutment cutting equipment to process the cuttable abutment columns and produce personalized abutments. When the doctor requires the use of a finished abutment or a ground abutment for restoration, the factory can only complete the abutment processing by manual grinding by technicians, which is time-consuming and labor-intensive.

[0008] Preferably, a clamping hole is provided on the top of the cutting machine clamp, the lower surface of the reverse clamp is movably connected to the inside of the clamping hole, and the lower part of the reverse clamp is designed with reference to the clamping hole of the cutting machine clamp.

[0009] Preferably, a mounting hole is provided at the bottom of the cutting machine fixture, the mounting hole is communicated with the interior of the clamping hole, the reverse clamp screw is movably connected with the interior of the mounting hole, and the reverse clamp screw mounts the reverse clamp on the cutting machine fixture.

[0010] Preferably, an interface is provided on the top of the reverse clamp, and the lower surface of the finished abutment is movably connected to the inside of the interface. The upper interface of the reverse clamp is designed with reference to the implant interface and is used to bridge the finished abutment or the ground abutment.

[0011] Preferably, a second threaded hole is opened inside the reverse clamp, and the top and bottom ends of the second threaded hole are respectively connected to the interface and the inside of the first threaded hole, and the bottom end of the central screw of the base is connected to the internal thread of the second threaded hole, and the finished base or the ground base is clamped on the upper interface of the reverse clamp through the central screw of the base.

[0012] Compared with the prior art, the utility model provides a cutting machine reverse clamp, which has the following beneficial effects:

[0013] 1. The cutting machine back-clamp fixture is provided with a back-clamp fixture, a back-clamp fixture screw, a finished abutment and a central screw of the abutment. The back-clamp fixture is first installed on the cutting machine fixture using the back-clamp fixture screw, and the finished abutment and the grinding abutment are clamped on the upper interface of the back-clamp fixture through the central screw of the abutment, so as to realize the digital cutting of the standard model abutment, realize the multi-purpose of one machine without increasing the equipment cost, and reduce the working pressure of the denture processing plant.

[0014] 2. The cutting machine's reverse clamping fixture can completely process the maxillofacial position and shoulder position of the abutment through reverse clamping. There is no need for manual grinding and adjustment after cutting. The abutment after cutting and the abutment design data remain highly consistent. In this case, the factory can complete the design of the abutment, crown, and model at one time. After the design is completed, digital processing can be carried out simultaneously. There is no need to design and process the abutment first, and then scan the abutment to make the crown. This reduces the shipment process and greatly shortens the overall shipment cycle of the factory. BRIEF DESCRIPTION OF THE DRAWINGS
