Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature.

[0045] It is worth noting that, unless otherwise specified, the methods used in this utility model are all conventional methods; and the raw materials and equipment used are all conventional commercially available products, and their sources are not specifically limited.

[0046] like Figure 1 As shown, this embodiment provides a boron nitride cold-pressed ceramic blank handling device, which includes a fixing part and a gripping part.

[0047] In this embodiment, the fixing part has a cross-shaped structure, that is, four support arms 1 are evenly distributed on the periphery. A guide ring is welded and fixed at the center of the four support arms 1. Furthermore, the support arm 1 has a cylindrical structure, and external threads are machined from the middle to the end.

[0048] Each arm of the fixed part is equipped with a corresponding gripping part, so it can be understood that there are four gripping parts evenly distributed along the circumference of the fixed part.

[0049] The gripping part and the fixing part are hinged. Furthermore, the fixing part is provided with multiple horizontally adjustable structures, thereby allowing the fixing part to be hinged to the corresponding gripping part via these horizontally adjustable structures. Figures 2-4 As shown, the main body of the horizontally adjustable structure 2 includes a first adjusting sleeve 202 and a lower connecting rod 203. The first adjusting sleeve 202 has a smooth interior and can be slidably fitted onto the threaded section of the support arm 1, and is welded and fixed to the lower connecting rod 203, forming a T-shaped structure. First positioning nuts 201 are installed at both ends of the first adjusting sleeve 202. Therefore, when it is necessary to fix the horizontal position of the first adjusting sleeve 202, tightening the first positioning nuts 201 at both ends will clamp the first adjusting sleeve 202. Furthermore, considering the stability of the clamping, this embodiment also designs a circumferential limiting structure between the first adjusting sleeve 202 and the corresponding threaded part. A simpler design is to machine an axial groove through the end on the support arm 1 and to provide a radially inwardly protruding edge on the inner side of the first adjusting sleeve 202. Thus, during the assembly process, firstly, a first positioning nut 201 is screwed in, and the thread can be properly engaged by controlling the groove width; then, the first adjusting sleeve 202 is fitted and the protruding edge is slid into the groove, thereby achieving circumferential limiting without affecting axial sliding; finally, another first positioning nut 201 is screwed in.

[0050] The end of the lower connecting rod 203 is hinged to the gripping part via a shaft support. The end of the lower connecting rod 203 has a shaft hole structure, and a double-ear support is provided on the gripping part. The two structures are connected by a rotating shaft, thus forming a planar hinged structure.

[0051] The gripping part includes a pull rod 5 and a hook structure, with the pull rod 5 connected to the hook structure 3. The pull rod 5 has a structure similar to the support arm 1, with a pull ring 501 at its end, connected to an external hanging point via a pull rope or chain, and having an external thread machined from the middle to the end. A second adjusting sleeve 302 is fitted onto the pull rod 5. The second adjusting sleeve 302 is welded and fixed to the hook structure, and second positioning nuts 301 are also installed at both ends of the second adjusting sleeve 302. The positioning principle is the same as that of the first adjusting sleeve 202, and will not be described further here. The hook structure is an inverted L-shaped hook structure, with the aforementioned double-ear support at the upper part, and is hinged to the lower connecting rod 203 to achieve hinged connection with the fixed part.

[0052] The hook structure 3 includes a vertical section and a horizontal section. Specifically, in this embodiment, the two sections consist of three components: a first square tube 303, an L-shaped connecting rod 8, and a second square tube 9.

[0053] The vertical section consists of the first square tube 303 and the vertical section of the L-shaped connecting rod 8, forming a coaxial nested telescopic rod structure. Among them, the first square tube 303 serves as a fixed section, and its upper part is fixed to the second adjusting sleeve 302 and the double-ear support in sequence; the vertical section of the L-shaped connecting rod 8 serves as a movable section, which is welded and fixed to the transverse end as a whole to form an L-shaped structure.

[0054] The horizontal section of the L-shaped connecting rod 8 and the second square tube 9 also form a coaxial nested telescopic rod structure. The second square tube 9 is used to support or clamp the ceramic blank.

[0055] In this embodiment, the L-shaped connecting rod 8 is specifically used as an embedded structure in the two telescopic rod structures, meaning that the cross-sectional dimensions of the two sections are smaller than the corresponding first and second square tubes, respectively, to achieve an embedded sliding fit. Furthermore, to enable rapid dimensional adjustment, multiple positioning through holes 304 are machined on the first and second square tubes and the L-shaped connecting rod 8 for positioning adjustment. Specifically, a ball-head plunger positioning pin 10 with a pull ring is used for positioning the first square tube 3; for the second square tube 9, the positioning hole on the upper side is machined as a countersunk hole structure and positioned using a countersunk bolt 11. The purpose of this design is that the positioning adjustment of the first square tube 303 can be quickly achieved by inserting and removing the positioning pin; while for the second square tube 9, since it is the main load-bearing component, a more stable connection method is required, hence the bolt connection. To prevent the bolt protrusion from damaging the surface of the ceramic blank during gripping, the positioning hole on the upper outer side needs to be machined as a countersunk hole and fitted with a countersunk bolt 11. It should be noted that in other embodiments, if the cross-sectional dimension of the second square tube is smaller than that of the L-shaped connecting rod, i.e., the exposed working end is an L-shaped connecting rod, then the positioning hole on the upper side of the L-shaped connecting rod needs to be machined into a countersunk hole structure.

[0056] An elastic reset mechanism is also provided between the fixing part and the gripping part; optionally, the main body of the elastic reset structure in this embodiment is a tension spring 4, with hooks fixed at the ends of the support arm 1 and the pull rod 5, and the tension spring 4 is hung on the two hooks, so that the gripping part is kept in a slightly taut state during non-transportation processes. The advantage of this design is that by designing the tension spring 4 to have a suitable pre-tension force, during the gripping process, the operator only needs to lightly lift the hook to fully unfold the gripping part and place the ceramic blank in it; then, during the lifting process, the gripping part rotates along the hinge axis to contact the blank, and under the influence of the blank's own weight, the gripping part will provide sufficient gripping force for transport.

[0057] Optionally, in this embodiment, each pull ring 501 is connected to a pull rope 6, which is a metal cable. The four pull ropes 6 pass through the guide ring and are connected to a pull ring 7 at the end. The pull ring 7 is connected to an external hanging point.

[0058] Working principle:

[0059] The lifting device is first connected to the pull ring of the device in this embodiment, and then moves to the lifting position as a whole, approaching the ceramic blank during the lowering process. When it is about to touch the blank, the operator gently lifts the four hooks or fixing parts to unfold the device. As it continues to descend, the operator makes fine adjustments to bring the device to the designed gripping position. Then the lifting device stops lowering and starts lifting. The pull ring pulls the rope to rise, which causes the hook structure to tend to flip inward. As it contacts the blank, the friction or the reaction force generated by the contact position increases, thus successfully gripping the blank and lifting it to the designated height to start the transfer process.

[0060] After the lifting device reaches the transfer destination, it is lowered at a uniform or slow speed. When it contacts the designated release position, the weight of the billet is supported by the transfer position, which causes the tension of the rope to decrease. As a result, it tends to return to its original position under the action of the tension spring. The operator only needs to gently lift the four hooks or the fixing part to unfold the device and complete the release process.

[0061] It should also be noted that in the above embodiments, the two-stage horizontal adjustment structure formed by the fixing part and the gripping part is not a redundant or ineffective design. Its function is to adjust the tension angle of the pull rope 6 by changing the relative position of the support arm 1 and the pull rod 5, so as to better adapt to different scenarios. Because the different tension angles of the pull rope 6 on the pull ring 501 result in different force magnitudes and angles applied by the second square tube 9 to the blank, the gripping force and angle can be controlled within a suitable range by adjusting the lateral position of the pull rod 5, and the preload of the tension spring 4 can be changed to better adapt to the scenario requirements.

[0062] Finally, it should be noted that the above content is only used to illustrate the technical solution of this utility model, and is not intended to limit the scope of protection of this utility model. Simple modifications or equivalent substitutions made by those skilled in the art to the technical solution of this utility model do not depart from the essence and scope of the technical solution of this utility model.
