Detailed Implementation

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] See Figure 1-4 A columnar material clamping and fixing device for stone processing includes three grippers 1, which are distributed equidistantly in a ring. A driving unit 2 drives the three grippers 1 to move centripetally simultaneously. Each gripper 1 includes a guide rail 101 pointing towards the center. A fixing block 102 is fixedly installed at the end of the guide rail 101 away from the center. A clamping block 103 extending to the outside of the guide rail 101 is slidably connected above the guide rail 101. An adjustment unit 3 is provided between the clamping block 103 and the fixing block 102 to control the distance between them.

[0023] The drive unit 2 includes an upper fixed plate 202 and a lower fixed plate 203. A bevel gear 204 is disposed between the upper fixed plate 202 and the lower fixed plate 203. A gear disk 205 meshes above the bevel gear 204. A worm gear groove 206 is disposed above the gear disk 205. A connecting block 207 meshes above the worm gear groove 206. A chuck 1 is mounted above the connecting block 207. This part is a three-jaw chuck mechanism. By such an arrangement, driving one of the bevel gears 204 to rotate can simultaneously drive the connecting block 207 to perform the same movement.

[0024] The clamping block 103 has a weight-reducing hollow hole 104 in the middle. The end of the clamping block 103 away from the fixing block 102 is fixedly installed with a protruding snap-fit ​​tooth 105. This setting can reduce the weight of the clamping block 103 and at the same time stably clamp the stone.

[0025] The adjustment part 3 includes a guide shaft 302 that is rotatably connected to the clamping block 103. The guide shaft 302 is threadedly connected to the fixing block 102. By rotating the guide shaft 302, the position of the clamping block 103 can be finely adjusted, thereby enabling the clamping block 103 to engage with the stone.

[0026] The lead shaft 302 is provided with a plug-in positioning part 303 at the end away from the clamping block 103. The plug-in positioning part 303 is used to connect the electric mechanism.

[0027] In embodiment 2, the drive unit 2 includes three annularly distributed main telescopic cylinders 201. The free end of the main telescopic sleeve 301 is fixedly connected to the gripper 1, and the fixed ends of the main telescopic cylinders 201 are relatively fixed. The three main telescopic cylinders 201 are connected to the inlet and outlet. Under the action of the same drive source, the three main telescopic sleeves 301 work simultaneously, thereby extending or retracting the same length. This arrangement allows for coarse adjustment.

[0028] The adjustment unit 3 includes a telescopic sleeve 301. The fixed end of the telescopic sleeve 301 is fixedly connected to the fixed block 102, and the free end of the telescopic sleeve 301 is fixedly connected to the clamping block 103. The telescopic sleeve 301 can be used to finely adjust one of the clamping blocks 103 by working alone.

[0029] To determine whether the clamping block 103 is in contact with the stone, one approach is to visually inspect it. During the coarse adjustment process, the displacement of the stone proves that one of the clamping blocks 103 is in contact with the stone. Another approach is to improve the clamping block 103 by installing a pressure sensor on the end face of the clamping block 103. When the pressure sensor is pressed, it proves that the clamping block 103 is in contact with the stone.

[0030] In use, the three grippers 1 move centripetally simultaneously under the action of the drive unit 2. When one gripper 1 comes into contact with the object being gripped, the operation stops. Then, the remaining adjustment units 3 are driven in sequence so that the gripping block 103 can fit tightly against the gripped stone. With this setting, the position of the grippers 1 can be quickly adjusted under the action of the drive unit 2, and then the position of the gripping block 103 can be finely adjusted by the adjustment unit 3, so as to adapt to irregularly shaped cylindrical stones.

[0031] It should be noted that in this paper, relational terms such as first and second are used only to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations.

[0032] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
