Description
Technical Field
[0001] This utility model relates to the field of cutting machine fixture technology, specifically a multi-nested cutting machine fixture. Background Technology
[0002] In the current field of cutting machines, especially in dental machining, the adaptability and compatibility of fixtures have become key issues restricting machining efficiency and cost.
[0003] Traditional cutting machine fixture systems have significant limitations: most machines are only equipped with basic fixed fixtures, which can only accommodate specific types or sizes of cutting materials; even if a few machines support fixture nesting, they can usually only nest 1-2 additional fixtures, which cannot meet diverse processing needs.
[0004] The cutting materials used in the dental field exhibit a high degree of diversity:
[0005] It includes common disc-shaped materials as well as a large number of non-disc shapes such as bar and block materials. Disc-shaped materials alone come in various specifications. Traditional original clamps are difficult to cover the mainstream sizes of 95mm, 98mm, and 106mm on the market. In addition, it involves a variety of special materials such as zirconium oxide, glass ceramics, and customized bases. Different materials have different requirements for clamping methods and limiting structures of clamps.
[0006] The diversity of these materials leads to obvious drawbacks in the existing processing mode: in order to adapt to different materials, multiple special equipment or frequent fixture changes are required, which not only increases the cost of equipment procurement and maintenance and occupies more production space, but also reduces processing efficiency due to the time-consuming replacement process, making it particularly difficult to meet the needs of small and medium-sized processing scenarios or multi-variety small-batch production.
[0007] Therefore, a multi-nested cutting machine fixture needs to be designed to solve the above problems. Utility Model Content
[0008] The purpose of this invention is to provide a multi-nested cutting machine fixture to solve the problems mentioned in the background art.
[0009] To achieve the above objectives, this utility model provides the following technical solution: a multi-nested cutting machine fixture, including a fixed base, wherein a fixing mechanism is provided inside the fixed base;
[0010] The fixing mechanism includes a fixing clamp, a first nested clamp, a second nested clamp, a third nested clamp, a fourth nested clamp, a fifth nested clamp, a sixth nested clamp, and a seventh nested clamp;
[0011] The fixing clamp is fixedly connected to the inner side of the fixing base. The top of the fixing clamp is threadedly connected to a first fixing shaft.

A support rod is fixedly connected to the middle of the inner side of the fixing clamp.
[0012] The first nested clamp is slidably connected to the inner side of the fixed clamp and the outer side of the support rod.

The outer side of the second fixed shaft is rotatably connected to the second limiting frame. The second limiting frame is rotatably connected to the inside of the bottom end of the first nested clamp.
[0013] The second nested clamp is slidably connected to the inner side of the fixed clamp and the outer side of the support rod. The top of the second nested clamp is located at the bottom of the first limiting frame. The bottom of the third nested clamp is threadedly connected to a third fixed shaft. The outer side of the third fixed shaft is rotatably connected to a third limiting frame. The third limiting frame is rotatably connected to the inside of the bottom end of the second nested clamp.
[0014] The third nested clamp is slidably connected to the inner side of the fixed clamp and the outer side of the support rod. The top of the third nested clamp is located at the bottom of the first limiting frame. The bottom of the third nested clamp is threadedly connected to a fourth fixed shaft. The fourth fixed shaft is rotatably connected to a fourth limiting frame. The fourth limiting frame is rotatably connected to the inside of the bottom end of the third nested clamp.
[0015] The fourth, fifth, sixth, and seventh nested clamps are slidably connected to the inner side of the fixed clamp and the outer side of the support rod, respectively, and the tops of the fourth, fifth, sixth, and seventh nested clamps are all located at the bottom of the first limiting frame.
[0016] Preferably, the tops of the first, second, third, fourth, fifth, sixth, and seventh nested clamps are all in contact with the bottom of the first limiting frame, and the outer diameters of the first, second, third, fourth, fifth, sixth, and seventh nested clamps are all the same, which facilitates fixing different cutting materials using different nested clamps.
[0017] Preferably, the fourth nested fixture has a circular fixing groove inside, and there are seven fixing grooves, which facilitates fixing the matching cutting material through the circular grooves.
[0018] Preferably, a second limiting shaft is fixedly connected to the inner side of the sixth nested fixture. The outer periphery of the second limiting shaft is hexagonal, and there are six second limiting shafts, which are symmetrically distributed on the inner side of the sixth nested fixture, so as to facilitate the fixing of the corresponding cutting material through the second limiting shaft.
[0019] Preferably, a fixing frame is fixedly connected to the bottom inner side of the seventh nested fixture, and the fixing frame is rectangular. Nine fixing frames are provided and symmetrically distributed on the inner side of the seventh nested fixture, which facilitates the fixing of the corresponding cutting material through the fixing frame.
[0020] Preferably, the first, second, and third nested clamps have the same outer diameter and shape, but different inner diameters that increase sequentially, so as to facilitate the fixing of cutting materials of different sizes through the three nested clamps.
[0021] Preferably, a first limiting shaft is fixedly connected to the inner side of the fifth nested fixture.

It is particularly suitable for small and medium-sized processing scenarios or multi-variety, small-batch production needs. Attached Figure Description

[0042] Example 1
[0043] Please see Figure 1-13 This utility model provides a technical solution: a multi-nested cutting machine fixture, including a fixed base 1, and a fixing mechanism 2 is provided inside the fixed base 1;

[0045] The fixing clamp 21 is fixedly connected to the inner side of the fixing base 1. The top of the fixing clamp 21 is threadedly connected to the first fixing shaft 212. The first fixing shaft 212 is rotatably connected to the outer periphery of the first fixing frame 211. The first limiting frame 211 is rotatably connected to the inside of the fixing clamp 21. The middle of the fixed inner side is fixedly connected to the support rod 213.
[0046] The first nested clamp 31 is slidably connected to the inner side of the fixed clamp 21 and the outer side of the support rod 213.

[0047] The second nested clamp 41 is slidably connected to the inner side of the fixed clamp 21 and the outer side of the support rod 213. The top of the second nested clamp 41 is set at the bottom of the first limiting frame 211. The bottom of the third nested clamp 51 is threadedly connected to the third fixed shaft 412. The outer side of the third fixed shaft 412 is rotatably connected to the third limiting frame 411. The third limiting frame 411 is rotatably connected to the inside of the bottom end of the second nested clamp 41.
[0048] The third nested clamp 51 is slidably connected to the inner side of the fixed clamp 21 and the outer side of the support rod 213. The top of the third nested clamp 51 is set at the bottom of the first limiting frame 211. The bottom of the third nested clamp 51 is threadedly connected to the fourth fixed shaft 512. The fourth limiting frame 511 is rotatably connected to the outer side of the fourth fixed shaft. The fourth limiting frame 511 is rotatably connected to the inside of the bottom end of the third nested clamp 51.
[0049] The fourth nested clamp 61, the fifth nested clamp 71, the sixth nested clamp 81 and the seventh nested clamp 91 are slidably connected to the inner side of the fixed clamp 21 and the outer side of the support rod 213, respectively. The tops of the fourth nested clamp 61, the fifth nested clamp 71, the sixth nested clamp 81 and the seventh nested clamp 91 are all located at the bottom of the first limiting frame 211.
[0050] The tops of the first nested clamp 31, the second nested clamp 41, the third nested clamp 51, the fourth nested clamp 61, the fifth nested clamp 71, the sixth nested clamp 81, and the seventh nested clamp 91 are all in contact with the bottom of the first limiting frame 211. The outer diameters of the first nested clamp 31, the second nested clamp 41, the third nested clamp 51, the fourth nested clamp 61, the fifth nested clamp 71, the sixth nested clamp 81, and the seventh nested clamp 91 are all the same, which makes it easy to fix different cutting materials through different nested clamps.
[0051] The fourth nested fixture 61 has a circular fixing groove inside, and there are seven fixing grooves, which facilitates the fixing of matching cutting materials through the circular grooves.
[0052] The sixth nested fixture 81 is fixedly connected to the inner side of a second limiting shaft 811.

[0054] The first nested clamp 31, the second nested clamp 41, and the third nested clamp 51 have the same outer diameter and shape, but different inner diameters that increase sequentially, making it easy to fix cutting materials of different sizes through the three nested clamps.
[0055] The fifth nested fixture 71 is fixedly connected to the inner side of a first limiting shaft 711. The first limiting shaft 711 has six pins, which are symmetrically distributed on the inner side of the fifth nested fixture 71, so as to facilitate the fixing of the corresponding cutting material through the first limiting shaft 711.
[0056] In actual operation, when this device is used, firstly, the first fixing shaft 212 is loosened by external fixing equipment, so that the first limiting frame 211 is in a horizontal state inside the fixing frame 911. At this time, the first nesting clamp 31 can be slidably connected to the inner side of the fixing frame 911 and slidably connected to the outer side of the support rod 213, so that the fixing frame 911 and the first nesting clamp 31 can be combined. At this time, the first limiting frame 211 can be rotated to a vertical state around the first fixing shaft 212, and the bottom of the first limiting frame 211 is in contact with the top of the fixing clamp 21. The first fixing shaft 212 is fixed by external fixing equipment, so as to ensure the stability of the limiting frame and the stability of the first nesting clamp 31. The material to be cut can be fixed by the first nesting clamp 31.
[0057] The first nested clamp 31, the second nested clamp 41, the third nested clamp 51, the fourth nested clamp 61, the fifth nested clamp 71, the sixth nested clamp 81 and the seventh nested clamp 91 can meet the cutting needs of various special materials such as zirconia, glass ceramics and personalized abutments in the dental field. There is no need to configure separate equipment for specific materials, which reduces equipment investment costs. A single clamping system can achieve compatibility with discs, bars, blocks and various special materials, avoiding the need to purchase multiple equipment due to differences in material type or size, reducing equipment procurement and maintenance costs, and saving production space. It is especially suitable for small and medium-sized processing scenarios or production needs of multiple varieties and small batches.
[0058] Furthermore, the installation methods of the second nested clamp 41, the third nested clamp 51, the fourth nested clamp 61, the fifth nested clamp 71, the sixth nested clamp 81, and the seventh nested clamp 91 are all the same as the installation method of the first nested clamp 31.
[0059] It consists of a fixed clamp 21 and seven nested clamps, namely the first to the seventh nested clamps 91, which are designed to adapt to different materials.
[0060] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitations, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element.
