Referring to fig. 1 to 9, in one embodiment of the present utility model, a ceramic blank holding device corresponding to an intelligent machining center includes:

the main body cylinder 100 is provided with at least eight channels 110 with the length direction consistent with the length direction of the main body cylinder 100 uniformly and circumferentially on the inner wall, and the channels 110 extend to one end of the main body cylinder 100 in the length direction;

The fixed fork assembly 200 is movably mounted in the channel 110, the fixed fork assembly 200 comprises two rod members 210 hinged with each other at the middle part in the length direction, one end of the rod member 210 in the length direction is clamped in the channel 110 in the radial direction of the main body barrel 100, and the other end of the rod member 210 in the length direction is provided with a clamping piece 220 for matching the ceramic blank;

A fixing ring 300 detachably connected to one end of the main body cylinder 100 in the length direction to form a butt joint, wherein one end of the fixing ring 300 away from the main body cylinder 100 is used for forming a connection with a machining center;

And an elastic member 500 disposed in the channel 110, wherein the elastic member 500 is clamped between the two rod members 210 on the fixed fork assembly 200, or the elastic member 500 is clamped between the fixed fork assembly 200 and the other end of the main body barrel 100.

In the prior art, due to the appearance and the strength specificity of the ceramic blank, the clamping at a proper strength and a proper position is difficult to realize in a mechanical clamping mode.

In the present utility model, corresponding to the ceramic blank clamping device of the intelligent machining center, at least eight channels 110 with the length direction consistent with the length direction of the main body cylinder 100 are uniformly and circumferentially arranged on the inner wall of the main body cylinder 100, and the channels 110 extend to one end of the main body cylinder 100 in the length direction. The cross-section of the channel 110 may be designed to limit the subsequent dropout of the fixed fork assembly 200 in the radial direction of the body cartridge 100.

The fixed fork assembly 200 is movably installed in the passage 110, and the ceramic blank is clamped by the end of the fixed fork assembly 200 away from the inner wall of the main body barrel 100. By providing the fixing fork assembly 200 at the passage 110 at the corresponding position in accordance with the shape of the ceramic blank, the ceramic blank can be suitably fixed by leaving the passage 110 free at a specific position. The fixed fork assembly 200 includes two rods 210 hinged to each other at the middle part in the length direction, and the extension of the fixed fork assembly 200 toward the center of the main body barrel 100 is achieved by the change of the angle between the rods 210. In particular, the extent of protrusion of the different fixed fork assemblies 200 varies for a particular shape of ceramic blank. One end of the rod 210 in the length direction is fastened in the channel 110 in the radial direction of the main body barrel 100; the radial clamping effect can be achieved by designing the cross section of the channel 110 and the shape of the end of the rod 210.

The fixing ring 300 is detachably connected to one end of the main body cylinder 100 in the length direction to form a butt joint. The main body cartridge 100 is fixed by one end of the fixing ring 300 and the other end is used for connection with a machining center. By the transition of the fixing ring 300, different body barrels 100 or different machining centers can be accommodated by changing the fixing ring 300. The purpose of the retaining ring 300 is not only to limit the removal of the retaining fork assembly 200 from the body barrel 100, but it is also important to complete the transition securement of the entire ceramic blank holder device. For example, after the entire mounting and fixing is completed, the ceramic blank holding device holding the ceramic ligands is fixed in the machining center.

A guide bar assembly 400 is coupled to one of the body cartridge 100 and the stationary ring 300 to form a guide engagement with the other. The presence of the guide bar assembly 400 allows for an optimized alignment of the mounting process of the retainer ring 300.

The elastic member 500 is disposed in the channel 110, and the elastic member 500 is clamped between the two rods 210 on the fixed fork assembly 200, or the elastic member 500 is clamped between the fixed fork assembly 200 and the other end of the main body cylinder 100. The elastic member 500 is used to form an angle change trend between the two rods 210 of the fixed fork assembly 200, so as to form a clamping force. In use, the clamping action of the fixed fork assembly 200 is not limited to compression clamping from the outer wall of the ceramic blank, and in other embodiments, with reference to fig. 9, support clamping from the inner wall may be performed by penetrating into the ceramic blank opening. Specifically, when the clamping is compression clamping, the elastic member 500 is clamped between the fixed fork assembly 200 and the other end of the main body barrel 100; in the case of support clamping, the elastic member 500 is clamped between the two rods 210 on the fixed fork assembly 200.

In use, the channel 110 is left idle at a specific position by arranging the fixed fork assembly 200 in the channel 110 at the corresponding position, matching the shape of the ceramic blank; depending on the manner of clamping, the elastic member 500 is selected to be installed between the two rod members 210 on the fixed fork assembly 200 or between the fixed fork assembly 200 and the other end of the main body cartridge 100; placing the ceramic blank into the main body cartridge 100 and then adjusting each of the fixed fork assemblies 200; attaching a fixing ring 300 to the main body cartridge 100; finally the whole is connected to the machining center by means of the fixing ring 300.

In summary, the ceramic blanks with various shapes can be adapted by selectively installing the fixed fork assembly 200, and the adjustment process of the fixed fork assembly 200 is manual, so that the possibility of damage is reduced; the above whole is connected to the machining center by the fixing ring 300.

In one embodiment, the other end of the main body cylinder 100 in the length direction is provided with a bolt corresponding to the position of the channel 110, and the tail of the bolt penetrates into the channel 110 to be matched with the fixed fork assembly 200.

In one embodiment, the elastic member 500 includes a hard rod and an elastic piece disposed at one end of the hard rod in a length direction.

In the present embodiment, in consideration of the fact that the entire elastic member 500 is provided so as to be deformable, the elastic member 500 has a problem of excessive deformation or excessive rigidity. The structure of the elastic member 500 is thus defined to include a hard rod through which rigidity and length dimension are achieved and an elastic sheet through which elasticity is achieved, and thus the entire elastic member 500 can provide a proper elastic force with less deformation. For example, the elastic member 500 may be a rod member having a belleville spring embedded in one end surface.

Referring to fig. 2, in one embodiment, two clamps 220 on the fixed fork assembly 200 are connected to each other.

In this embodiment, the two clamping members 220 are connected to each other, and the shape of the fixing fork assembly 200 is naturally fixed. While the entirety of the two clamping members 220 better adapts to the shape of the ceramic blank. The above characteristics are convenient in the case where the external shape of the ceramic blank is standard.

In one embodiment, the two clamping members 220 on the fixed fork assembly 200 are provided separately.

In the present embodiment, since the two clamps 220 are not connected, the angle between the two bars 210 can be properly adjusted during the installation of the fixed fork assembly 200. The above characteristics are convenient under the condition that the shape of the ceramic blank is specific, and particularly, the two rod pieces 210 on the fixed fork assembly 200 can be adapted to the ceramic blank to be set to different lengths, so that the matching flexibility is further improved.

Referring to fig. 3, in one embodiment, the guide bar assembly 400 includes a plurality of guide bars circumferentially connected to the stationary ring 300.

In the present embodiment, the fixing position of the guide bar assembly 400 is set on the fixing ring 300, and at this time, the operations of the main body cylinder 100, the fixing fork assembly 200, and the like are not interfered by the shielding of the guide bar.

In one embodiment, the fixing ring 300 is fixed to the main body cartridge 100 by a screw or by a clip.

Particularly in the case of fixing using a clip, a corresponding protruding ring is provided at a corresponding position of the fixing ring 300 and the main body cartridge 100; the fixing and stabilizing mode through the screw fixing mode has the advantage of fixing and stabilizing, and is beneficial to fixing of some large-size blanks.

In one embodiment, the fixing ring 300 clamps and fixes one end of the rod 210 in the channel 110 in the fixing fork assembly 200 with the main body cartridge 100.

In the present embodiment, the fixing of the fixed fork assembly 200 is achieved by the combination of the fixing ring 300 and the main body cartridge 100, and the introduction of some position limiters can be omitted. Specifically, a protruding shaft is provided on the rod 210, and a limiting groove is provided on the body cylinder 100 at a position corresponding to the rod 210, so that the rod 210 is fixed after the fixing ring 300 is coupled to the body cylinder 100.

In one embodiment, the free end of the clip 220 near the center of the retaining ring 300 is provided with a buffer layer.

In this embodiment, by adding the buffer layer on the free end surface of the clamping member 220, the possibility of damage to the ceramic blank in the process of pressing and clamping the clamping member 220 is reduced, and meanwhile, the material of the buffer layer is not too soft, otherwise, the position of the ceramic blank is not accurate. Therefore, the material of the buffer layer is preferably hard rubber or hard plastic.

In one embodiment, the free end of the clip 220 remote from the center of the retaining ring 300 is provided with a cushioning layer.

In this embodiment, by adding the buffer layer on the free end surface of the clamping member 220, the possibility of damage to the ceramic blank in the process of supporting and clamping the clamping member 220 is reduced, and meanwhile, the material of the buffer layer is not too soft, otherwise, the position accuracy of the ceramic blank is not good. Therefore, the material of the buffer layer is preferably hard rubber or hard plastic.
