The bottom plate 22 is mounted on the mobile platform 19 and is used to mount the mobile drive member 13 and the nail sand drive member 9.

[0031] Working method:

[0032] When the screw drive motor 21 drives the screw 18 to rotate, the threaded sleeve 191 is restricted from rotating by the movable platform 19, and the screw 18 pushes the threaded sleeve 191 to move along the length direction of the screw, and the slide guide sleeve 192 can slide along the length direction of the guide rod 15, so that the threaded sleeve 191 can push the movable platform 19 to move.

[0033] In some embodiments of the present disclosure, a motor substrate 20, a guide rod bearing seat 14 and a lead screw bearing seat 17 are additionally installed. The motor substrate 20 is installed on the support frame 16 for installing the lead screw drive motor; both ends of the guide rod 15 are installed on the support frame 16 through the guide rod bearing seat 14, and both ends of the lead screw 18 are installed on the support frame 16 through the lead screw bearing seat 17, wherein one end of the lead screw 18 is provided with the lead screw bearing seat 17 and is transmission-connected to the lead screw drive motor 21.

[0034] The lead screw 18 is rotatably mounted on the support frame 16 through a lead screw bearing seat 17 .

[0035] In some embodiments of the present disclosure, a vertical moving structure of a nail sand driving member is provided, and a guide rail 23 and a nail sand base plate 10 are additionally installed. The guide rail 23 is installed on the bottom plate 22, and the nail sand base plate 10 is slidably installed on the guide rail 23 for installing the nail sand driving member 9.

[0036] In some embodiments of the present disclosure, a connection structure between a piston rod and a sand-pinning substrate 10 is provided. A connection block 11 is additionally installed. The connection block 11 is installed on the sand-pinning substrate 10, and a movable driving member 13 is provided with a piston rod 12, and the piston rod 12 is connected to the connection block 11.

[0037] In some embodiments of the present disclosure, a structure of a clamp is provided. Figure 1-3As shown, the clamp 5 includes two clamping jaws, which are symmetrically mounted on the workbench 4. The clamping jaws include a clamping plate 51, a support column 52, a push-pull rod 54, a lock nut 55, a support seat 59 and a rotating cap 56. A slide groove 41 is provided on the top of the workbench 4, a through hole communicating with the slide groove 41 is provided on the side, a lock nut 55 is installed on the end surface of the through hole, the support seat 59 is placed in the slide groove 41, one end of the support column 52 is installed on the support seat 59, and the other end extends out of the slide groove 41 and is connected to the clamping plate 51, one end of the push-pull rod 54 is penetrated by a lock nut 55 and extends into the slide groove 41 to be rotatably connected to the support seat 59, and a rotating cap 56 is installed on the other end.

[0038] The two corresponding clamping plates 51 are used to clamp the gold ornaments, so that the gold ornaments to be processed can be installed on the workbench 4.

[0039] The slide groove 41 allows the support column 52 to move radially along the workbench. The support column 52 can drive the clamping plate 51 to move radially along the workbench. When the two clamping plates 51 move closer to each other, the two clamping plates clamp and fix the gold ornaments to be nailed; when the two clamping plates 51 move away from each other, the two clamping plates are separated from the gold ornaments and the clamping state is released.

[0040] In order to improve the force stability of the support column, Figure 3 As shown, reinforcing ribs 53 are added to improve the bearing capacity of the support column.

[0041] It should be noted that the push-pull rod 54 is provided with a threaded section for threaded connection with the anti-loosening nut. A rotation connection structure of the push-pull rod and the support seat: the push-pull rod and the support seat are connected through a bearing. The push-pull rod and the support seat can realize mutual rotation through the bearing.

[0042] In order to make it easier to turn the rotating cap 56, a force rod 58 is additionally installed. The rotating cap 56 is provided with a force through hole 57, and one end of the force rod 58 is inserted into the force through hole 57.

[0043] The through hole can be a through hole that passes through the rotating cap. Alternatively, it can be a blind through hole. When the force rod 58 is needed, the force rod is inserted into the through hole 57, and the force rod is used to drive the rotating cap to rotate, which can save effort compared to directly twisting the rotating cap. It can be understood that after the clamp clamps the gold ornaments to be nailed, the force rod can be pulled out.

[0044] How the fixture works:

[0045] The clamping jaw includes a clamping plate 51 , a support column 52 , a push-pull rod 54 , a locking nut 55 , a support seat 59 and a rotating cap 56 .

[0046] During the clamping operation, the rotating cap 56 is screwed respectively, so that the push-pull rod 54 is screwed into the anti-loosening nut 55, and the push-pull rod 54 pushes the support seat 59 to move axially toward the workbench, and the support seat 59 drives the support column 52 to move axially toward the workbench, and the support column 52 drives the clamping plate 51 to move toward the center of the workbench, so that the two symmetrically installed clamping plates 51 move toward each other, and the gold ornaments to be nailed on the workbench are clamped and fixed. After clamping, the rotating cap can be stopped.

[0047] To disengage, screw the rotating cap 56 respectively to make the push-pull rod 54 unscrew the anti-loosening nut 55, and the push-pull rod 54 pulls the support seat 59 to move axially away from the workbench, and the support seat 59 drives the support column 52 to move axially away from the workbench, and the support column 52 drives the clamping plate 51 away from the center of the workbench, so that the two symmetrically installed clamping plates 51 move away from each other, so that the two clamping plates are separated from the gold ornaments on the workbench, and the gold ornaments can be taken out from the workbench.

[0048] According to the above embodiments, the working mode of the utility model is as follows:

[0049] The gold ornaments to be nailed with sand are placed on the workbench 4, and the gold ornaments to be nailed with sand are fixed by the clamp 5. The screw drive motor 21 is controlled by the controller 2 to drive the screw 18 to rotate. The screw 18 pushes the threaded sleeve 191, and then the mobile platform 19 moves under the interaction of the threaded sleeve 191 and the sliding guide sleeve 192. The mobile platform 19 drives the mobile driving member 13 and the nailing driving member 9 to move together. When the nailing head 7 on the nailing driving member 9 moves to correspond to the surface of the gold ornaments to be nailed with sand, the screw drive motor 21 is controlled by the controller 2 to stop working.

[0050] Then, the controller 2 is used to control the mobile driver 13 to start, and the mobile driver 13 pushes the sand-pinning substrate 10 to move downward along the guide rail 23. When the sand-pinning head 7 and the surface of the gold jewelry to be sand-pinned are at a suitable distance, the controller 2 controls the mobile driver 13 to stop working and starts the sand-pinning driver 9. The sand-pinning driver 9 drives the sand-pinning piston rod 8 to drive the sand-pinning head 7 to sand-pin the surface of the gold jewelry to be sand-pinned. During the sand-pinning process, the controller 2 can also control the drive motor 3 to start, and the drive motor 3 drives the workbench 4 to rotate. The gold jewelry rotates in a circle with the workbench, and sand-pinning can be performed on different positions on the surface of the gold jewelry.

[0051] When the sand nailing is finished, the controller controls the driving motor 3 to stop working, the mobile driving member 13 is started, and drives the sand nailing substrate 10 to move upward along the guide rail 23, and the sand nailing head 7 moves upward away from the workbench 4. When the sand nailing head and the workbench 4 have a suitable distance, the mobile driving member 13 is controlled to stop working, and the sand nailing head 7 stops moving upward, so that the clamping effect of the clamp 5 can be released, and the gold jewelry obtained by sand nailing can be taken out from the workbench, and the sand nailing work is completed.

[0052] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived from these are still within the scope of protection of the invention of the utility model.
