Examples

As shown in fig. 1 and 2, a carbon-carbon composite material clamp for a high temperature furnace comprises a rectangular installation frame 1, wherein a connecting assembly is arranged in the middle of each of four side walls of the installation frame 1, one end of the connecting assembly, which is close to the center of the installation frame 1, is connected with a carbon-carbon composite material clamping plate 8, the connecting assembly comprises a threaded rod 2, a sliding rod 3, a threaded sleeve 10, a spring 4, a push rod 5 and a push plate 7, the threaded rod 2 penetrates through the middle of the side wall of the installation frame 1 and is in threaded connection with the side wall of the installation frame 1, one end of the threaded rod 2, which is positioned inside the installation frame 1, is coaxially connected with an external threaded seat 9 with a diameter larger than that of the threaded rod 2, one end of the external threaded seat 9, which is far away from the threaded rod 2, is connected with the sliding rod 3, one end of the push rod 5 is provided with a sliding hole 6 matched with the sliding rod 3 and is in sliding connection with the sliding rod 3 through the sliding hole 6, and one end of the push plate 7, which is far away from the sliding rod 3, is connected with the push plate 5, one side that push rod 5 was kept away from to push pedal 7 is connected with carbon-carbon composite splint 8, thread bush 10 and external screw thread seat 9 threaded connection, push rod 5 outwards extends towards the one end outer fringe of slide bar 3 and forms and be annular first extension 11, thread bush 10 inwards extends towards the one end inner fringe of slide bar 3 and forms and be annular second extension 12, second extension 12 is located one side of first extension 11 towards push pedal 7, and the internal diameter of second extension 12 is between the external diameter of first extension 11 and the external diameter of push rod 5, spring 4 overlaps and locates on slide bar 3 and both ends connect external screw thread seat 9 and first extension 11 respectively.

This anchor clamps are when using, and the mould is arranged in the middle of installation frame 1 promptly between four coupling assembling, adjusts carbon-carbon composite material splint 8 through coupling assembling and carries out the centre gripping to the mould, and concrete operation is as follows:

in an initial state, the spring 4 is fully relaxed, when the die is used for the first time, whether the threaded rod 2 needs to be rotated to adjust the position of the carbon-carbon composite material clamping plate 8 is judged according to the size of the die and the shrinkage of the spring 4, and the judgment standard is based on the condition that the distance between the four carbon-carbon composite material clamping plates 8 is slightly smaller than the outer profile of the die; when the distance between the four carbon-carbon composite material clamping plates 8 is slightly smaller than the outer profile of the mold, the distance can be finally reduced through the springs 4 to enable the carbon-carbon composite material clamping plates 8 to clamp the mold and apply pressure to the mold to ensure stable clamping, and the threaded rod 2 does not need to be rotated to adjust the position of the carbon-carbon composite material; when the distance between the four carbon-carbon composite material clamping plates 8 is slightly smaller than the outer profile of the mold, the threaded rod 2 needs to be rotated to adjust the position of the carbon-carbon composite material. Even if the threaded rods 2 do not need to be adjusted for the position of the carbon-carbon composite clamping plate 8, it is still checked whether the four threaded rods 2 are in the same length in the mounting frame 1, if not, in the same length, or in the same length, if in the same length, no adjustment is needed, so as to ensure that the mold is in the centered position when finally clamped. After the operation or the inspection is finished, the threaded sleeve 10 is rotated on the external threaded seat 9, the first extending portion 11 is driven to move towards the direction of the threaded rod 2 through the second extending portion 12, the push rod 5 is driven to move towards the direction of the threaded rod 2 on the slide rod 3 through the slide hole 6, and finally the push plate 7 and the carbon-carbon composite material clamping plate 8 are driven to move towards the direction of the threaded rod 2, so that the distance between the four carbon-carbon composite material clamping plates 8 is slightly larger than the external profile of the mold, the mold is conveniently placed between the four carbon-carbon composite material clamping plates 8, after the mold is placed, the threaded sleeve 10 is rotated in the reverse direction to the initial position (in the position, the second extending portion 12 does not press the first extending portion 11, and the elastic force of the spring 4 is completely applied to the carbon-carbon composite material clamping plate 8 to clamp the mold), and the mold can be clamped. And, in the use after this, the mould size change is little or with the size mould change when changing the mould, then can needn't rotate threaded rod 2, only through rotate the operation of thread bush 10 can, through the operation of thread bush 10, can convenient and fast carry out the pre-compaction to spring 4, it is more convenient to operate, need not to be pressed spring 4 by operating personnel manual always when the installation mould, can liberate operating personnel's both hands, improves the simple operation nature. When the size change of the replacement die is large, the threaded rod 2 needs to be rotated for adjustment, and after the threaded rod 2 is rotated, whether the position of the threaded rod is proper or not is judged according to the above standard.

The push rod 5 is rotatably connected with the push plate 7 through a bearing, and an orientation component for limiting the direction of the push plate 7 is arranged between one side of the push plate 7 facing the push rod 5 and the side wall of the mounting frame 1.

Push rod 5 rotates with push pedal 7 to be connected, advances to inject push pedal 7 by directional subassembly simultaneously, can avoid push pedal 7 to rotate along with push rod 5 when push rod 5 rotates, makes push pedal 7 orientation fixed, and 7 misplaces of push pedal of being convenient for can not be fine accomplish the centre gripping to the mould.

The orientation component comprises a guide rod 13 and a guide hole 14 formed in the side wall of the installation frame 1, one end of the guide rod 13 is connected with the push plate 7, and the other end of the guide rod 13 penetrates through the guide hole 14 and is in sliding connection with the guide hole 14.

The push plate 7 is limited through the matching of the guide rod 13 and the guide hole 14, the push plate 7 is prevented from rotating along the normal plane of the push rod 5, and the directional assembly is simple in structure and practical in function.

One side of the push plate 7 facing the push rod 5 is connected with two guide rods 13, the two guide rods 13 are symmetrically arranged by taking the push rod 5 as a center, and the two guide rods 13 and the push rod 5 are positioned on the same horizontal plane.

The push plate 7 is limited by the orientation components at the two sides of the push rod 5, so that the push plate 7 is more stable.

A supporting seat 15 for supporting a mold is arranged at the center of the bottom of the mounting frame 1.

The support base 15 is used to support the bottom of the mold when the mold is installed.
