At present, most of the materials (zirconia ceramic blocks) used for processing false teeth on the market are disc-like in shape, and the steps on the edge are used for positioning in the processing process. In addition, according to the shape characteristics of the denture materials, all denture engraving and milling machine fixtures on the market at present are disc fixtures, and when the denture material is used, the denture material is firstly placed into the fixtures, then the denture material is placed into the gland, and the denture material is fixed by screwing the compression screws on the gland. However, with this jig, since the gland is annular, the portion of the gland that contacts the denture material cannot be machined, and the denture material cannot be applied to the denture.

Therefore, in order to solve the above problems, in the prior art, a jig is provided in a disc shape having a notch, the notch occupies one third to two thirds of the entire jig, and the edge of a part of the denture material is exposed. However, since a part of the edge of the denture material is open, the denture material is easily cracked when the edge of the denture material is pressed, and the denture material is scrapped. Moreover, with this jig, a part of the denture material cannot be processed, and this leads to a waste of the denture material to some extent. Therefore, a new clamping device is urgently needed.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Unless otherwise indicated, the technical means used in the examples are conventional means well known to those skilled in the art.

Referring to fig. 1-5, the utility model discloses a clamping device for engraving and milling machine, comprising a clamp 1 and a gland 2 detachably fixed on the clamp 1, wherein the clamp 1 is arc-shaped, the bottom surface of the clamp is provided with a step 4 for supporting a porcelain block 3, the edge part of the gland 2 extends out of the clamp 1, and the extending part corresponds to the step 4; the gland 2 and the clamp 1 are fixed by screws 5. The method specifically comprises the following steps: the top surface of the clamp 1 is provided with a plurality of limiting holes, the gland 2 is provided with a plurality of through holes 7 symmetrical to the limiting holes, and the screws 5 penetrate through the through holes 7 and are fixed in the limiting holes.

It should be understood that: the edge of the inner ring of the gland 2 has a part extending out of the clamp 1, and the width of the extending part is the same as that of the step 4 and is symmetrical up and down. The edge of the top surface and the bottom surface of the porcelain block 3 is provided with an annular step 12, and the part of the step 4 and the gland 2 extending out of the clamp 1 is just clamped on the annular step 12 of the bottom surface and the top surface of the porcelain block 3 respectively, so that the porcelain block 3 is fixed.

Further, in order to avoid the ceramic block 3 from loosening or falling or directly clamping and breaking in the process of processing the ceramic block 3, an elastic piece 6 is arranged between the gland 2 and the clamp 1. It should be noted that: the elastic member 6 is a part having elasticity, such as a spring, a rubber block, etc., and the spring can be selected from a rubber spring or a metal spring, which is selected according to actual requirements.

Further, in order to increase the stability of gland 2 after fixing with anchor clamps 1, be provided with arc wall 8 at the top surface of anchor clamps 1, spacing hole setting is in the bottom surface of arc wall 8, and gland 2 is fixed in arc wall 8, and the marginal portion stretches out the bottom surface of arc wall 8 to avoid gland 2 to slide or misplace on anchor clamps 1.

Furthermore, the elastic element 6 is sleeved on the screw 5, specifically: the limiting hole is arranged in a step shape and is divided into a smooth hole section 9 and a threaded hole section 10 from top to bottom, and the internal thread of the threaded hole section 10 is matched with the screw 5, so that the clamp 1 and the gland 2 are fixed by screwing the screw 5. And the elastic member 6 is arranged in the unthreaded hole section 9, and the screw 5 is fixed in the threaded hole section 10 through the elastic member 6. It should be noted that: outside elastic component 6 part stretched out light hole section 9, when gland 2 was fixed with anchor clamps 1, can compress elastic component 6, when loosening screw 5 back, elastic component 6 can be automatic with gland 2 jack-up to accomplish the change to porcelain block 3 in the shortest time.

Further, another setting mode of the elastic element 6 is to set the elastic element 6 between the gland 2 and the bottom surface of the arc-shaped groove 8 and far away from the limiting hole, and at this time, the limiting hole is directly an internal thread hole and is not set to be step-shaped. Likewise, after the screw 5 is loosened, the elastic member 6 automatically pushes up the gland 2, thereby rapidly completing the replacement of the porcelain block 3. In order to provide sufficient space for the elastic member 6, a plurality of grooves for receiving the elastic member 6 may be provided on the bottom surface of the arc-shaped groove 8, so that the elastic member 6 is pressed into the grooves.

Furthermore, in order to enable the clamping effect of the arc-shaped clamp 1 and the gland 2 to be better, the ceramic block is prevented from being scrapped due to displacement or crack generated in the process of clamping the ceramic block 3. Therefore, the bottom surface of the gland 2 and the edge of the outer ring of the gland are provided with the arc-shaped boss 11, that is, when the gland 2 and the clamp 1 are fixed, the outer side wall of the arc-shaped boss 11 is attached to the side wall of the arc-shaped groove 8. The arc boss 11, the arc groove 8, the clamp 1 and the gland 2 are the same in shape and are all arc-shaped; and the central angle of anchor clamps 1 is less than or equal to 120 to along with the reduction of central angle number of degrees, stability between anchor clamps and the porcelain piece is just also worse, to the utility model discloses, when the central angle of anchor clamps 1 is 120, stability between anchor clamps 1 and the porcelain piece 3 is best. In order to increase the area for processing the ceramic block 3 and increase the number of teeth to be processed, the clamping amount of the ceramic block 3 clamped by the clamp 1 can be adaptively modified. And the elastic member 6 is in contact with the bottom surface of the gland 2 at a position away from the arc-shaped boss 11. The utility model discloses set up arc boss 11 in gland 2's bottom surface, use it with the cooperation of elastic component 6, make the effect that forms C shape pincers between gland 2 and the anchor clamps 1, though only the third of porcelain piece 3 has been held, also reached fine tight effect of clamp equally. As is clear from fig. 6 and 7, the number of the teeth processed after the porcelain block 3 is clamped by the clamping device disclosed by the invention is obviously equal to the number of the teeth processed after the porcelain block is clamped by the annular fixture.

Further, in order to avoid the edge angle of the inner ring of the gland 2 from covering the surface of the porcelain block 3, thereby influencing the processing of the porcelain block 3, the edge of the top surface of the gland 2, which is close to the inner ring, is an inclined surface inclined towards the center of the gland 2, and the lowest part of the inclined surface is abutted against the side wall of the annular step 12 on the edge of the top surface of the porcelain block 3.
